this workshop. What I will be discussing today is based on these two recent papers that I did in collaboration with Jose Calderón, Matilda Delgado, who are also PhD student at IFT Madrid, and our advisor Angel Leurang. So let me start with some introduction about the things that I will be telling you about and why it is interesting to look at them. So suppose you have a theory that is not sitting at a minimum of the potential but rather it is moving on the slope. This is something very general that can happen, for example, if you break supersymmetry and then you generate a potential of an awakened. We refer to such situations as dynamical tadpoles since these are tadpoles for dynamical fields, and so they are a different thing than topological tadpoles such as Ramón-Ramón tadpoles, which are for non-dynamical fields and in post-consistency conditions on your theory. As opposed to that, dynamical tadpoles are not inconsistencies by themselves, but you really have to take them into account. And in fact, it was recently shown that ignoring these kind of tadpoles can lead to some violation of swampland conjectures, and this was in fact one of the original motivations for this work. The typical situation we will be dealing with is when you have a theory that has no tadpole and you have a nice and smooth solution for your equations of motion. Then you add some ingredients in the construction in such a way that a dynamical tadpole appear. The presence of this term in the potential has the effect of destabilizing your solution. And since obviously the equation of motions are modified, and then in order to solve the tadpole you allow your solution to run in such a way that it acquires some dependence on spacetime coordinates. And this is the general case, but in fact we will always be considering space dependence for this talk. So we have these running solutions that are sourced by dynamical tadpoles, and they have some interesting features. In particular, they often contain metric singularities, or they involve strong coupling regimes, and this obviously makes their interpretation difficult. What we can do, and what is also the plan for this talk, is to investigate these solutions further by looking at many examples that we have from string theory, and see if we can identify some general properties or some universal pattern that is based on this example that we studied. Another question that I will address during the talk is how swampland conjectures manifest in these kind of setups, and in particular I will focus on the co-bornness conjecture since it seems to play a key role in the discussion. Then in the second part of the talk I will also try to connect with the distance conjecture. So let me now introduce a bit this co-bornness conjecture and what it is about. This can be seen as a particularization of this statement that in quantum gravity you cannot have global symmetries, and this is in a sense the oldest among the swampland conjectures, and we really have a lot of evidence for it. We know it is true in any string theory compactification, and more recently we also have an argument for it that comes from holography and ADS-CFT correspondence. So we expect that there are no global symmetries in quantum gravity, and what McNamara and Vafa proposed was to look at a particular kind of symmetries that we can construct in interiors of gravity, and the idea is that in gravity we are allowed to have topology changing transitions, and since topology changing transitions can be interpreted as co-bornisms, any topological charge that is associated to a topological symmetry must also be a co-bornism variant. So if you have a topological charge that is associated to your original manifold m, and there is a topology changing transition that takes you to a different manifold n, this means there is a co-bornness between these two manifolds, we require that this topological charge is a co-bornism variant so that it doesn't change in the transition, and this means that that a natural global charge to look at is the co-bornness group, which I call omega. So for manifolds of dimension k, you say that there is a co-bornness between any two of them, if there this joint union is the boundary of another manifold with one dimension more, and this is the usual geometric notion that you have in mind when you talk about co-bornness, but in fact there is also another way to look at it, which is equivalent. Suppose you have a theory of quantum gravity that has these space-time dimensions, and then you are willing to define its co-bornness group as the set of in equivalent configurations of the theory, where any two configurations that can be connected by a domain wall are identified, and this makes sense because if your theory in the dimensions is arising as the compactification of a higher dimensional theory on a compactification space of dimension k, which is by the way what is always happening in the context of string theory compactifications, then these two definitions are just the same because any non-trivial co-bornness between two compactification spaces will correspond to a domain wall if you look at it from the perspective of the lower dimensional theory. So to recap, in a semi-classical theory of gravity, you can have topology change in transitions, and there is a natural global charge which is given by the co-bornness group, but since we expect there are no global symmetries in quantum gravity, what the co-bornness conjecture is telling us is that at the fundamental level this co-bornness group actually has to vanish, so all co-bornness classes must be trivial. What does it mean? If your manifold m is carrying some global charge, then you really want this charge to disappear, and there must be a transition in the theory that allows you to shrink this manifold to a point, or in other words this manifold is co-born to the empty manifold, so it's the boundary of something else. And equivalently from the perspective of the lower dimensional theory, this means that there must exist a boundary on which your theory cannot own, and we call this a wall of nothing since it is an end of the world wall with nothing behind. So, suppose you cannot do this in your low energy description with some smooth cuborgism, but maybe you can do it with some singular configuration that is not part of your low energy effective theory, but is a valid configuration in the full quantum theory of gravity. And the idea is that on top of what you have in the IR, there must exist certain defects that really must be there in the theory. And in other words, an interesting implication of this conjecture is that you can use it to predict the existence of defects. And the idea is that whenever you find that the co-bornness group of your theory is non-trivial, then something you can do is to include some additional ingredients to produce new co-bornness in such a way that otherwise non-trivial co-bornness classes are killed. As a very simple example, just take a two-sphere, which is the boundary of a three-sphere, so this is trivial in co-bornness. However, if you put some U1 magnetic flux, this is non-trivial because the flux cannot just disappear, so the sphere cannot shrink. And the way to solve this is to include the magnetic monopole as a localized source that is able to absorb this flux in such a way that the sphere can shrink. Now, obviously, there are many co-bornness groups you can think of, and which one you have to look at depends on the theory that you are considering. For instance, if your theory contains gauge fields, then you would like your gauge field to extend to the co-bornness in a smooth way. And you can use this to predict the existence of D-brains in type 2 string theories just because there are Raman-Raman gauge fields that can be turned on. Formally, given a P4μ1 gauge field, the Bianchi identity for the field strength implies that the total magnetic flux over any orientable manifold is a co-bornness invariant, and this is what is labeled in the co-bornness classes. This also corresponds to the existence of d-minus p-minus 2 for symmetry, which is given by shifting the magnetic dual potential. And the way to kill it is to introduce d-minus p-minus 3-deffences, which are magnetic monopoles, again. Now, suppose that you turn off the gauge fields and you want to use only the fact that string theory contains spinors, then you have to look at spin co-bornness, so the co-bornness group for manifolds for which you have a definite choice of a spin structure. Let me just mention some of the examples. For zero-dimensional manifolds, the spin co-bornness means set, and this is generated by a positively oriented point. To kill this class, for example, in M-theory, you have a boundary, and such an object is, in fact, very familiar since it is given by the Aurawe-Wittham wall. Similarly, for type 2a, you have an o8 as a boundary, which is the Aurawe-Wittham wall wrapped on the M-theory circle. Another example is for dimension 1 manifolds. In this case, the spin co-bornness is z2, and the way to kill it in, for example, circle compactification of type 2b is to introduce to the orientation of seven planes. Another yet possibility is when your theory makes sense on non-orientable manifolds, and it also has fermions. In this case, the co-bornness group you must consider is even more general. Now, in all these examples, all these objects were very explicit and very familiar, but there can also be other setups where you find a non-trivial co-bornness group, and there is no known object that kills it for you. And then you have to rely on the conjecture to claim that such an object indeed exists. This, for example, was used recently to argue for the existence of bifolds, which are a generalization of orbifolds and orientifolds, and to put constraints on the rank of gauge groups in dimension greater than six. The fact that these co-bornness defects are not always known is also true in our setup. Sometimes we will be able to identify them, and they are very familiar objects, such as orientifold planes or d-brains, but there were also some cases in which it was not obvious how to characterize them, and we had to rely on the conjecture to claim that such objects indeed existed. Let us now go back to our case with dynamical tadpoles. There are basically two tadpole lessons that we learned by looking at examples. The first lesson is what we call finite distance. We observe that in the presence of a dynamical tadpole, which is controlled by an order parameter t, the space-time-dependent solution of the equation of motion can only extend up to a finite space-time distance, which I call delta, and this delta scales inversely with the strength of the tadpole. The larger the tadpole, the smaller the distance. This scaling obeys power law, where the exponent, we determined it case by case, and it was always true in Minkowski-like examples and one in ADS-like ones. The second lesson is what we call dynamical cobaltism. The proposal is that there must exist a physical mechanism that is able to cut off for use space-time dimensions at this distance scale delta of the finite distance lesson, and this corresponds to the cobaltism effect of the original theory with the tadpole. The reason why I call it a cobaltism effect is precisely because this is the effect that would be predicted by the cobaltism conjecture. These are the two lessons that I wanted to show you, and we are ready to see them at work in some examples. The examples that I would like to discuss include the conifold theory, then some toroidal compactifications with three-form flux, also magnetized models. We have non-super symmetric TND strings, in particular the USP32 theory. Finally, we will see a model building application where we are able to use these ideas to get a semi-realistic MSSM-like particle physics model. The first example I want to discuss, and which is a prototype for also the other ones, is based on the near-horizon limit of n regular D3 brains at a conifold singularity, which is famously ADS-5 times T11, with 10 units of Ramon-Ramon 5-form flux on the T11. This is the Klebano-Wittham solution, which is the first picture on the left. We can consider adding m units of Ramon-Ramon 3-form flux on the S3 that is inside the T11, but this modification is dramatic, and the resulting solution is the Klebano-Zitlin solution, which is the picture in the middle. The reason I say dramatic is because of the nate singularity that this solution develops at some finite value of the radial coordinate. What is happening is that in the back-reactive metric, the T11 shrinks to zero at some finite value of the radial coordinate, but this will not be a problem because the 5-form flux also disappears by then. However, the S3 is supporting the 3-form flux. This is also shrinking, but the flux is constant. The flux density to infinity, the back-reaction is also infinite, and this is why you get a singularity. The smoothing out of this singularity was studied by Klebano and Strassler, and it corresponds to the third picture on the right. The idea is that you can give this S3 a finite size in such a way that the solution terminates in a smooth way. Space time is capped off at this point in the sense that after that you have no meaning for the radial direction. Until now, this was just a review, so let me now to reinterpret the whole thing in our language based on TATPOL and running solutions. That there is a TATPOL for the dilaton can be seen very explicitly from the 5D effective filtering point of view if you look at the 5D action. Introducing M units of flux generates a potential for the dilaton, which is this blue term, and which, as you see, is of a runaway kind and has no meaning. In the dilaton, a question of motion, there is a source term, and the only way to balance it and keeping the dilaton constant is to introduce some space-time dependence for some other scalar, which is the NSNS section that comes from integrating the NSNS2 form over the two spheres inside the T11. In this way, the TATPOL is sold and the specific space-time dependence that you get is this logarithmic running in the radial direction. This is also equivalent to introduce NSNS3 form flux, which has two legs along the S2 and one other leg in the radial direction in space-time, so that the combination of the three form fluxes is imaginary self-dual. Then we can compute the distance to the singularity and compare it with the TATPOL, and what we get is in agreement with the finite distance lesson with a scaling coefficient equal to 1. In this language, the Klebanos-Trasler solution is providing you with the coborgis effect you need for our dynamical coborgis lesson. The next example is also based on three form fluxes, but now in the context of toroidal compactifications. So consider that to be on a five torus with Ramon-Ramon three form flux along the direction x1, x2, and x3 inside the T5. This introduces a TATPOL for the dilaton, and in fact the equation of motion that you get is very similar to the one that we had before. The way to solve it is also very similar, since you can introduce some NSNS3 form, which has two legs along the compact direction y1 and y2, and another leg in one of the space-time directions, which I call y. Since the combination of these fluxes is an imaginary self-dual, it is easy to study the back reaction on the metric. It is convenient that we put this y-coordinate together with the coordinate of the torus, so to get complex coordinates z1, z2, and z3. The word factor obeys a Laplace equation that is sourced by the f3 flux, and in particular it develops two singularities at some finite values of the y-coordinate. Also if you compute the distance between these two singularities, you can check that this distance is finite, and it obeys the scaling law of our finite distance lesson with scaling coefficient equal to 2. The last step is that we have to identify the co-bordance defect that is able to remove these singularities and make this direction compact. This co-bordance defect of 2B on T5 is provided by orienting for 3 planes, which will appear as sourced in the Laplace equation, and in the end what we get is a compactification on T6. This is of course familiar, and what is new is that the 4D model is obtained in two steps. You start from a 5D model, and then you end up in 4D. We like to call this a spontaneous compactification because it is triggered by the tadpole that was present in the original 5D theory. The way to solve the tadpole, as we saw, is to introduce dependence on a special coordinate, and what we discover is that this coordinate along which you run is forced to be compact. Let me move to the next example. We consider type 2B, compactified on T4, where the orienting for action is flipping the coordinate of the first T2. There are four orienting for 07s that are localized at the fixed points of the first T2, and also 16 D7 brains, and of course they are orienting for images. Something we can do is to introduce M units of D7 world volume magnetic 3-fold flux along the second torus, and this breaks supersymmetry and generates a tadpole for the dilaton and the color modulus of the T2. One way to see this is that the charge of these objects cancel, but there is some unbalanced extra tension. Now the interesting part comes that is we have to solve the tadpole. One possibility that we have is to introduce magnetization along two of the six non-compact coordinates, which equal Z3, in such a way that the combination of fluxes you get is supersymmetric. Then the discussion of the black reaction can be carried out in a way similar to our previous example, if you consider the lift to F theory. In the F theory picture, our volume magnetic flux corresponds to G4 flux. Then you can look at the warp metric, and again you find that the warp factor is singular, and that the singularities are separated by a finite distance, that is by the way inversely related to the tadpole, and the way in which these singularities can be removed is again by making these two directions compact, and the cobalt means the effect that you get are some extra orientival 07 planes and D7 brains. The next example that I want to show you is quite interesting, since it has to do with non supersymmetric 10D strings, and in fact as soon as you try to formulate these non supersymmetric string theories, tadpole will appear because you have no protection by supersymmetry. Let's focus on the 10D non supersymmetric USP32 theory that was constructed by Sugimoto. This can be obtained as an orientival of type 2B, which is very similar to type 1, and the difference is that you have positively charged orientival 09 instead of negatively charged 1, so this is why you have the SP projection. Cancellation of Ramon-Ramon tadpoles requires that you also introduce 32 antidenides, and the resulting theory is anomaly free. There is no space-time supersymmetry, and there is a dilaton tadpole, which is this blue term here that appears as a cosmological constant there in the 10D action. This implies that the theory does not admit a maximally symmetric vacuum, and solutions with lower supersymmetry must be looked for. Actually there is a solution with 9D Poincaré invariance, which was originally found by Dudas and Murat, and this is a running solution where both the metric and the dilaton depend on one of the special coordinates, which I called y. There are two singularities, one is at zero and one at infinity, but despite appearances these are separated by a finite distance, something that was already noted in the original paper by Dudas and Murat, and it is also easy to check that this distance obeys our scaling law with exponent n equal to 2. Now a legitimate question to ask is which is the cowardice, the effect that is able to remove these singularities? The answer is that we do not know, so in a sense we stop at the same point where Dudas and Murat did in their paper. What we can say is that such an object should exist by the co-boarding's conjecture, and in fact it was recently proposed that such an object is given by AD8. However, there is also another way to solve the tackle, which is to introduce magnetization, and I will be sketchy about it because this is not new, we already saw it in the other examples. I just want to mention it because it is quite nice that you start with a non-super symmetric theory and you are able to get a supersymmetric compactification of it. The idea is that you introduce some word-volume magnetic fields along three different complex planes, and this triggers a compactification of an orientation of T6. The last example is now to have maybe a bit of fun and see if the standard model is the outcome of one of these spontaneous compactifications that I have been telling you about. The idea is that you start from a 6D theory with a dynamical tackle and you solve it by a running solution, which makes some dimensions compact so that in the end you have a 4D model and the spectrum is an MSSM-like. So you can start from type 1, compactified on an orienting fold of T4, with 32 magnetized D9 brains and some D5 brains that are obtained as induced charges. You also have some orienting fold O9 planes and O5 planes. You can find the details in the table. There are different stacks of brains and these numbers N and M correspond to the rapid number and the magnetic flux units for each of the two T2. Just for completeness, let me just mention that this system can be tidalized to a system of intersecting D7 brains. Okay, in this setup, Ramon-Ramon tuples, you can check that they are cancelled, but they are uncanceled NSNS tuples. One way by now familiar to solve them is that you can introduce magnetization along two of the 6D space-time dimensions. This triggers a spontaneous compactification to 4D, where the co-ordinate defects correspond to some extra orienting fold O5s and also D5s that are needed to absorb the orienting fold charge. And in this way, Ramon-Ramon tuples are still cancelled. So in the final model, you have some extra stacks of brains, which are label B and C. And this 4D model can be made supersymmetric if you choose appropriately the areas of the T2s. And this guarantees that in the end, you have no tuples that you have cancelled the tuples. Now, if you look at the spectrum of this theory, this is a three-family MSSM-like spectrum, which in fact was already built by Marchesano and Schu. What is new is our interpretation of a 6D model that spontaneously compactifies to 4D. An interesting observation is maybe that in the original 6D theory, you knew nothing about the standard model. And all the MSSM-matter, the X-chiral multiplex, and the electro-wicked gauge sectors all arise from the co-ordinates' brains. So in this sense, the spontaneous compactification from 6 to 4D that was triggered by dynamical co-ordinates implies not only that some dimensions are removed, they are made compact, but also that there are some new degrees of freedom that appear. Okay, this is not yet the end of the story since in all the cases that we considered so far, the relevant co-ordinates was a wall of nothing. But in principle, domain walls that interpolate between different theories are also possible. So one may ask what is the difference and how to discriminate between these two different kinds of co-ordinates. Suppose you have a dynamical tuple in your theory, and then you find a running solution that solves this tuple. Then you can look at the scalars in your theory, and some of them we run, and you can compute the distance that they traverse in field space. Now our proposal is that if the scalars run into a wall that is at infinite distance in field space, then this must be a wall of nothing. But if the wall is at finite distance in field space, then this must be a domain wall that takes you to a different theory. What is interesting about this proposal is that in some sense it allows you to relate the co-board this conjecture and in particular walls of nothing with the distance conjecture. So the idea of the distance conjecture is that as you go along geodesic paths of infinite distance in field space, you will get an infinite tower of states that becomes exponentially light. If walls of nothing appear at infinite field space distances, we would expect from the distance conjecture that there are some light states coming down, and then we can also play a bit with the scalings that we have to relate, for example the mass of the sdc tower with geodesic quantities as the spacetime distance to the wall or the curvature scalar, as we will see in the examples. These are again examples from string theory, which include a massive type 2a, m-theory compactified on a Calabi-Yau threefold with g4 flux, and as a final example a circle compactification of 4d n equal 1 effective field theories with some axiom flux. So let us start with a massive type 2a, so type 2a with an additional Ramon-Ramon 0 form flux, which is the Romance mass parameter m. This theory is supersymmetric, but it has a dilaton tuple that is controlled by m, and it admits a one of BTS solution with 90 Poincare invariance, where both the metric and the dilaton depend on one special coordinate, which is x9. This metric becomes singular at some finite value of the x9 coordinate, which corresponds to the vanishing of the wall factor. And it is easy to check that the distance in spacetime to the singularity is finite, and it also base our scaling relation with coefficient n equal to 2. The singularity is smoothed out by the non-cogordin's defect of type 2a, so this is an orienting for 08 plane with possibly some additional d8 grains that are needed to absorb the flux, and this corresponds to a wall of nothing. In fact, this matches the type 1 prime setup and singularities that were discussed, for example, many years ago by Polchinsky and Wittner. There is a single scalar in the theory, which is the dilaton, and this runs off to infinity at the singularity, which is exactly what we would expect to happen at a wall of nothing. We can also compute the distance in spacetime and the curvature scalar in terms of the distance in field space, and then relate them to the mass of the light states, and in both cases we get some power loss scaling. However, this is not the most general solution that you can have, since you can also put d8 grains along x9, and if each of them will serve as a domain wall that is interpolating between different type 2a theories corresponding to different values of the romance mass parameter. The form of the solution is the same we had before, except that now this function z is piecewise linear with different slopes between each pair of d8. This means in particular that the dilaton stays finite across the domain walls, and this is in agreement with our general picture. The next example is interesting because it allows us to address the question of what would happen if you are at finite distance in field space, but you hit a singularity. So what do you get in this case?  So let's see. The setup that we consider is M theory compactified on a Calabi out threefold in the presence of G4 flux that is closely related to Witten's strongly coupled atherotic. The 5D effective action contains some scalars which are V, which is the hypermultiplex scalar and corresponds to the breathing mode of the of the Calabi out. And then you also have the color moduli which are vector multiplex scalars and these are the BI's. There are also axioms that come from integrating the 4 4 over a basis of four cycles which are these A's and also they are dual 4 4 potentials lambda. This G4 flux acts as a source and generates a tuple for the overall volume and color module which is this blue term. And this action also contains also contains a boundary term to include four dimensional localized sources and this correspond to M5 brains that are wrapped onto cycles and this serve as domain wall in the solution. This is a running solution that sold the tuple and both the metric and the color moduli are allowed to vary along one of the 5D coordinates that is the coordinate transfers to the M5 brain walls. Everything is controlled by these one dimensional harmonic functions H which are linear in the in the direction Y. So the picture is very similar to the one that we had before and the only difference is that now we have a bunch of piecewise linear functions which are this H which control the devolution of the Calabi Yaw along the 5th dimension. Okay, in particular if the world Calabi Yaw goes to zero size what happens is that you eat our other weekend wall. On the other hand if you have an M5 wrapped on a two cycle then you have an interpolating domain wall between different values of the G4 flux which jumps as you as you cross the domain wall. Now something we can ask is what happens if the evolution of the Calabi Yaw is such that it suffers a flop that is a topology change in transition which in this case can occur dynamically. A typical flop is for example when you have a positive two cycle that goes to zero and then it becomes negative. This was already studied by Green, Schalm and Schiu and they checked that the solution is continuous across the flop which for simplicity can be located at Y equals zero. One can choose a more convenient basis for the color module in which the flop curve corresponds to W minus U. Then what you have to do is to match the solution on both sides of the flop in such a way that all these harmonic function H are continuous and in particular this is true for the harmonic function that corresponds to the to the flop curve. What is interesting for us is that these functions are finite at the flop point and since the color moduli depends on them also the color moduli are finite so despite the singularity in modular space the solution remains at finite distance and this answers our original question about what happens if you have a singularity which is at finite distance so you do not get a wall of nothing you will get interpolating walls and in fact you can also check that the G4 flux is discontinuous across the flop and so the flop works as it was an M5 brain interpolating cobaltism. What this points to is that walls of nothing really have to do with infinite distances in field space. The last example that I want to discuss is based on a circle compactification of four-dimensional N equal one theories with axiom flux. For simplicity we take a single axiom-saxiom pair so A is your axiom with unit periodicity, S is its it's its axiomic partner which we canonically normalize and call it phi. Then we take we take an ansatz and compactify to 3D. Regarding the axiom as a zero form gauge field we can introduce two units of flux for its field strength on the on the circle and we also allow for a general section profile to account for the back reaction. By looking at the 3D action we see that there is a dynamical tackle for a linear combination of the radion and this axiom which is precisely induced by the presence of the axiom flux. This tackle can be solved by a running solution where you can keep the axiom constant but you allow the other scalars to acquire a non-trivial profile with dependence on one of the 3D coordinates which I call R to suggest it is a radial coordinate and there is for this I will explain it in a second. Observe that as R goes to zero the radion blows to infinity and this means that your compactification circle is shrinking to zero and then the metric becomes singular. The axiom also goes to infinity in this limit so according to our general picture the singularity should correspond to a wall of nothing that is capping off your spacetime so that you have no region with negative so it is in fact a radial coordinate. Keeping the leading order as R goes to zero you can compute how the spacetime distance and the scalar curvature scale with the field space distance and then you can get the relationship between the mass of the light states and these geometric quantities and as we expect we get some power law scalings. Something interesting that I want to point out is that this setup matches precisely with the EFT string solutions that were recently studied by these authors. They were looking at BPS axionic strings with co-units of axiom charge and which back react on a complex scalar and there is in fact a clear dictionary between our running solution in the S1 compactification and their EFT strings namely the angle around the string maps to our compactification circle then the string monodromy for the axiom map to the axiom flux around the maps to the axiom flux on the on the S1. The radial coordinate in the complex plane around the string sorry was lost so the radial coordinate in the complex plane around the string maps to the direction of the running so the running along the coordinate are and this is semi infinite because you have a wall of nothing at the singularity. Then the the string back reaction on the section which is realized as the string argiflow maps to the running of the section that for us is sourced by the dynamical tadpole induced by the axiom flux and then the the scalars that run off to infinity as one reaches the string core map to the scalars that are running off to infinity as you eat the the wall of nothing in particular the fact that this wall of nothing cannot be described within the effective theory exactly correspond to the fact that in the in the EFT string setup the EFT string is regarded as as an UV given the effect the the upshot of of the analysis in this landslide paper was the distance the distance of axionic string conjecture which states that infinite every infinite field distance limit of 4d and equal one EFT consistent with quantum gravity can be realized as an argiflow UV endpoint of an EFT string using the dictionary that I showed you before this can be translated in our language to the statement that every infinite field distance limit in this setup can be realized as they're running into a wall of nothing abortness in a circle compactification of the theory with some with some axiom flux then we can make a wild jump and suggest that this may even be more more general so that every infinite field distance limit of an EFT consistent with quantum gravity can be realized as they're running into a wall of nothing co-ordinates in the in the theory or in a compactification of the theory so I was maybe faster than I thought but I I I can conclude this point so let me recap what what we did what to study the the properties of space dependent solutions in theories with dynamical tadpoles what we learned was that this solution must have a finite extent which is inversely related to the tadpole and on top of that there is a physical mechanism by which spacetime is cut off and this is provided by the co-ordinates the effect of the co-ordinates this of the co-ordinates conjecture and one natural question that one can still ask is is about time dependence and this would imply a singularity in time so it will certainly be interesting to look at that also from a phenomenological or cosmological perspective and then we we try to connect with the the distance the distance conjecture and what we saw is that that infinity in field space is is really connected with with walls of nothing and then one one question that that will be interesting to explore is whether there are other one-plan conjectures that enter this this tadpole game so we we hope to address this this question in the in the future and with this I I think I can conclude and I I thank you for for your attention okay so a bit earlier I don't know if there are people who who make this group photo present now maybe okay maybe not okay let's let's just proceed with the discussions and so are there any questions yes I have a question so very nice talk general bro so I have a question about the couple questions one is the collavia three-fold case you were talking about the flows in the extra dimension extra face direction in the context of flop did you also study the four cycles shrinking there well we we look at it and we considered as a variety modulus just the volume of the world calabi out and if one does this naively then and then if you study the so if you study the situation in which the world calabi out shrinks if one does the computation naively you will get you will get that the the distance in space time is finite and and it obeys our finite distance lesson then one one may may not be so happy with that because if the world calabi out shrinks you are losing control of of the theory so this is something I guess I could be a criticism and just want to make sure maybe I maybe just I'm not sure I completely understood what you said so let me ask my question again so suppose you have a collavia three-fold with a let's say just for the concrete that's considered a p2 inside the collavia so it's a four cycle and you can change the moduli of the collavia the compact collavia such that this p2 shrinks to a point that's a finite distance in the collavia so this can happen a finite distance so according to your conjecture if I understand correctly if you vary this collavia over a line interval where this four cycle shrinks then you expect that there should be another side because otherwise you're getting a somewhere with finite distance and you're not getting it so you saw it shouldn't have been a infinite distance I'm just asking you if that's the case and if so I'm not sure what the other side is I'm just trying to understand whether you're making such a prediction and if so can you check it because it should be relatively straightforward to check if it's true or false okay I got it I got it now well then yes our proposal is that that should correspond to an interpolating wall since you are at finite distance and then I do not know how to answer right now but I since the the only case we considered where you have a singularity at finite distance was the flop case and in that case it was clear that you had two different theories at the flop with the flop serving as a domain word but in the case that you that you are mentioning well I do not have a a definite answer now right these are going to be challenge challenges for the conjecture because there are these things like terminal singularities or other ones which stops and you don't know the other side in the collavia jar so it suggests that there's no other side but they are finite distance so I think it'd be interesting to study them and if indeed your conjecture is true then at least in the category of supersymmetric compactification there must be an easy proof of it so in other words you should be able to say why if for example if you take a collavia and you fiber it over some geometry and let's say get a g2 out of it then it must be an interplay between condition of having a supersymmetric g2 let's say and and what is the other side or not or it stops and so on so from the viewpoint of a fiber geometry so there should be a I would say at least in the supersymmetric category there could be a proof for counter example to the conjecture would be interesting to study so that was one question the other one is so you were trying to connect the distance conjecture also to these to these cobaltism walls so the distance conjecture would be is usually formulated in a situation where things are static so when things are varying dramatically then that's going to be not correct for example when in the string example you mentioned where you have for example in an axiom or so forth or similar to what happens in f theory where you have elliptic vibration then at infinite distance in in in tau space the circular strength and well of course if you use as a circle compactification you would think that it's it stops because because on how you look at it but it's the end of a cigar or what but there's no masses there's no tower of masses modes there so that even the naïve the distance conjecture says there's a tower of states in the actual colabia metric where you write the elliptic vibration with the correct metric there's nothing singular happening there it's just a coordinate singularity so there is no evidence of the tower of states so how are you how are you mentioning how are you connecting the distance conjecture with these because in the generic cases i'm familiar with things were very too dramatically to be adiabatic so you don't have a you don't have a situation where things are static enough to apply the distance conjecture so perhaps i don't know how you think about it in those cases okay well in the last example that i showed the the one with the s1 compactification that that one seems seems fine to me since it is it is equivalent to the formulation by lans et al where they study strings these eft strings as a way to attain infinity when you approach the string core so in in that case i think at least to me it seems the connection is clear so so what do you mean by clear that that's not clear to me so do you have a tower there you're claiming there's a tower of states there for example let me just make sure i understand take the take let's take an eight-dimensional version of it so you have like fd area elliptic three elliptic k3 so you have a p1 and there are some points where elliptic vibration strings at some point so elliptic vibration string means tower was to infinity and therefore it's a bit of a distance in tau space but there is no tower of states near the d7 ring so the fd area description there's a d7 ring and there's no apiary tower so what do you mean by that tower i'm not i'm missing it i'm not quite understanding okay well it is true that we are we are not able to identify i would say any concrete tower in the in the in the in the examples we looked at what we the the reason why we i mean the the way in which we were trying to connect with the distance conjecture was just to say okay whenever we we we observe that whenever we run into a wall of nothing there are scalars that are running off to infinity if you look at the distance travels traveled in in field space so we are not claiming that we are able to identify any any any tower indeed so thank you other other questions or comments well i have myself a kind of general question so i guess in for this kind of full-fledged quantum gravity cobaltism theory it's not mathematically well defined but i wonder if there's some sort of intermediate version which is between geometry usual geometric cobaltism and this quantum gravity cobaltism which can be mathematically well defined and well indeed in the kind of examples that we that we studied which we propose as some sort of dynamical realization of this cobaltism conjecture where you really identify some mechanism that is able to cut off space time so you find these walls of nothing well i i don't know if i can formulate it in some more mathematical rigorous way but it is also true that if if you look at it from the perspective of compactification spaces then you can you can look at the at the cobaltism groups in the in the usual geometric sense so in that case that is mathematically well defined but for this kind of this type of kind of solution so you say you would you would consider kind of geometric manifolds with particular kind of solutions of some fields with some singularities that that how would you propose it to define mathematically i as i as i told you at the beginning you you you can look at these cobaltism from a more physically motivated perspective which is you look at the effective theory and you see if the theory can be connected to another one via a domain world or if it ends to nothing and this is the perspective that we took in these examples or you can look at compactification spaces and look at the more geometric mathematical thing so i guess from a mathematical point of view these walls you kind of include them by hand just possibly that there are some defects yeah the reason in which we identify them is uh in most cases these objects are already known so we we already know what they are and in that case it is easy when they are for example d-branes of or or antifold planes and and that is easy there was for that there was the the usp32 case which was more subtle because in that case it was not obvious which the defect was and in fact in that case we we were not able to identify it okay maybe i have a question related to what you just were discussing so in some cases as you said we don't know how to identify these domain walls and uh in the paper we wrote with Jake uh when we had the examples that we didn't know how to construct and uh simple example of this type to be in 10 dimensions and we expect that to have a boundary but naively that sounds like a very difficult thing to do given the chirality of the theory and all that there's no no-go theorem so it's in principle possible but there will be have to be very strange boundary conditions mixing up the the the the the self-duality of some of the form around one field which has some kind of a chirality in it mixing up with the gravity and all that in some form so there will be some very bizarre boundary conditions on these domain walls now coming to your conjecture in that context if you imagine i do not know if your conjecture also has the inverse that is if if you assume that what we said that there is no the cobaltism is trivial that means there is a domain wall and therefore according to your conjecture you would think that okay there must be some field that infinite distance which gives you that domain wall in type to be but the only field that you have in that context i think i can think of is just a coupling constant type to be and in that case how going to infinity the theory becomes weakly coupled in the weakly cobalt theory there is no such domain while we are aware of because i think we already know the domain wall so somehow this would be against the fact that we we thought we understood the perturbative objects rather well in this theory so i would expect that there should be something non perturbative maybe a tie goes to high or something which we are not familiar with that would do the job but how would your conjecture fit with the with the triviality of the cobaltism for type to be i i would say let me let me let me think for a second because this is something we we discussed that at some point what we are saying is that uh yes when whenever you have a wall of nothing there are if you interpret this as whenever you have a wall of nothing then you have a scalar standing off to infinity then i i i agree with with with this criticism so i'm not sure i have a definite answer right now okay thank you other questions comments if not let us thank general reggae for talk for the talk and uh discussion so i don't know if the cts people are present here who who would want to take a picture yeah we are supposed to take a look now okay so yeah if you if you don't mind you can turn turn on your cameras and we'll okay someone is missing


Hello everybody! In today's video, we will discuss ZFS file system, its structure, peculiarities and downsides. ZFS or Zetabyte file system is a special file system initially created by Sun Microsystems for the operating system called Solaris. It supports huge amounts of data, combines the concepts of a file system, physical disk and volume manager, and offers simple management methods for storage volumes. It is a next-generation file system initially designed for NAS solutions with improved security, reliability and performance. Unlike many other systems, ZFS is a 128-bit file system offering a virtually unlimited capacity. ZFS is an open-source project licensed under CDDL, which is Common Development and Distribution License. If you want to use ZFS out of the box, you'll have to install either a free BSD or an operating system using the Illumus kernel. Illumus is a fork of the open Solaris kernel. If you want to use ZFS on Ubuntu, you need to add the support features manually. But that's a pretty easy thing to do and it involves running a few commands. We will explore it in detail a bit later. But now let's talk about pros and cons of this file system. Talking of ZFS advantages, the full bin can be distinguished. It has a simplified pattern of administration that combines management of volumes, radar arrays and the file system. All you need to manage volumes, redundancy levels, file systems, compression ratios and mount points is just a few commands. This approach also simplifies monitoring as there are less levels to be considered. Another advantage is related to ensuring data integrity. While some data is written, this checksum is calculated and written as well. Later, when the data is read, the checksum is verified again. If the checksum doesn't match the read data, ZFS identifies an error. After that, the file system tries to repair such an error automatically. Also, ZFS is perfectly scalable with the possibility of adding new storage devices, cache management options and so on. The copy and write feature. In most file systems, data is lost forever when overwritten. On the other hand, in ZFS the new information is written to a different block. When the write operation is complete, the file system's metadata is updated to point to the new information. This helps to preserve the old data if the system crashes, or if another unfortunate event happens. This file system features integrated storage options such as replication, the process of creating copies of data on multiple devices, deduplication, a technique for eliminating duplicate copies of repeating data and reducing the storage load. And compression is the option that saves disk space and adds more speed, as the number of bits required to represent data is reduced. Snapshots are consistent reflections of the entire data representing the form it existed in at a single point in time. And cloning is used to create copies of snapshots. However, as any other file system, ZFS does have a few drawbacks. When its storage capacity is used by 80% or more, the ZFS performance tends to degrade heavily, and this is a commonplace problem for many file systems. When the current pool eats up 80% of the available storage, you should either expand the pool or migrate it to a storage system with a logic capacity. There is no way to reduce the storage pool. You cannot remove devices of VDEVs, which censor virtual devices, from the pool after they have been added. Also, there are limitations in changing the redundancy type. Except for switching a single disk-based pool to a mirroring pool, you cannot change the redundancy type. Having chosen the type of redundancy, the only solution is to destroy it and create a new one, while restoring data from backups or another location. Hello friends! If you need to recover deleted data, view or restore removed browser history. Hetman Software products will help you. Follow the link in the description. Download the necessary program for free. Install it and analyze the disk. The utility will show you the data you can recover, so you will be able to view it or get it back. In our channel and blog, you will find solutions to any problem, from installing an operating system or configuring it to fixing possible bugs and errors or optimizing mobile gadgets. Our specialists will answer any questions you ask in your comments under the videos or articles. Now, let's explore how to install ZFS on a Linux operating system with the example of Ubuntu version 2004. You will need the terminal for installation, so press the key shortcut Ctrl-LT to open it. Then run this command to check application updates. When the command is entered, the system will ask you for the root password. Type it and press Enter. For installation, use another command. Type Y to confirm the installation command and press Enter. It starts the software installation process. To check ZFS installation, use this command. As a result, the program's version will be displayed. Now you can create a storage pool with a VDEV, a virtual device. A storage pool is a set including one or several virtual devices where data can be stored. A ZFS pool, also known as ZPool, is a top-level data container in this file system. It is used to create one or several file systems or data sets or block devices or volumes. These file systems and block devices are then capable of using the remaining pool space. All operations in partitioning and formatting will be performed by ZFS. A virtual device, VDEV for short, may consist of one or more physical devices. It can be a pool or a part of it and it can have various redundancy levels, mirror, three-way mirror, RAID-Z, RAID-Z2 or RAID-Z3. RAID-Z is an implementation of a modified RAID-5. In ZFS, it is designed to overcome the right whole error, which often affects conventional RAID-5 systems. RAID-Z1 requires at least three disks, two for data storage and one for parity. RAID-Z2 should have at least four disks, two for storage and two for parity. Finally, for RAID-Z3, you need at least two disks for storage and three disks for parity. Now, let's find out how to build a RAID-Z system with a bunch of drives. First of all, let's decide which drives should be included. Use the FDisk utility to see what drives are connected and which of them are suitable for your purpose. Run this command to list the drives. As a result, you'll see a list of drives with detailed information on each one. For illustration purposes, I'll show you how to build a RAID-Z1. It's an equivalent of RAID-5 with one parity drive. Its design lets you use the array and have your data intact, even if one of the drives fails. I have three hard disks listed as div-sdd, div-sde, and div-sdf. I'll create a pool with the name Zdata, and here is the command to use. If there is an error, you can run this command adding F after Z pool create. It forces the command. To find the mounting point, run the command dfh after the pool is created. Now, you can see that the pool is mounting in Zdata. To modify the mounting point for your pool, use the following syntax. In this example, I used var slash p-double-o-l as a new mount point. Let's check the new point. You can create directories in the storage pool. For example, let's create a directory with the name myData. To view all ZFS storage pools in this system, run the following command. To see the configuration and status of every device within the ZFS pool, use the status command. To view events and eliminate issues, there is one more command. If you need to add one more hard disk to ZFS storage pool, you should run this command with the name of the disk that has to be added. After the disk is added, let's view the pool status. Finally, the last command that can be used to remove a ZFS storage pool. This file system lets you create snapshots of your pool. A snapshot is a read-only pointing-time copy of the file system created in a certain moment. You can create snapshots of whole datasets or pools. A snapshot includes an original version of the file system, together with all changes made after creating this snapshot. In other words, it's a read-only copy of differences. For creating snapshots, use the command ZFS snapshot, followed by the snapshot name. In this example, I used Zdata slash myData to create a snapshot. Use the following command to check the snapshot. The snapshot can be renamed if necessary. You can cancel the changes by rolling back the snapshot. However, it means you are going to lose all changes that took place after the snapshot was created. To go back to a certain snapshot, run the command ZFSrollback with the name of a certain snapshot. This will cancel all actions in this directory that were taken after the snapshot was created. This command will roll the system back to a certain date. When the rollback operation is complete, you can check that directory for availability of files that were deleted after the snapshot was created. Snapshots can be saved to a file and then recovered. Which is perfect for creating backups or for sending copies over the network. For example, with SSH to copy the file system. The send command sends a file system snapshot that can be redirected to a file or to another machine in a stream. The receive command receives such stream and writes a snapshot copy back to ZFS file system. For example, let's create one more snapshot and save it to a file using this command. And then let's restore it with another command. Using additional scripts, you can configure the file system to create snapshots automatically and send them to a server with SSH protocol. As I mentioned before, ZFS lets you compress data automatically. Taking into account the computing power of present-day CPUs, this option is very useful because the reduced volume of data means there is less data to be read and written physically, which results in faster input-output operations. ZFS offers a wide range of compression methods. The default option is LZ4, a high-performance substitute for LZJB that provides faster compression and extraction in comparison with LZJB. While using a somewhat higher compression ratio, to change the compression ratio, use this command. Or even change the compression type with another command. You can check the currently used compression ratio with this command. The safest choice is LZ4, as it is much faster than the other options, while it retains a very good level of performance. All things considered, ZFS is obviously the file system to offer you a wide range of opportunities. Not only does it let you manage your data in a very effective and innovative way, but it can also recover data without interrupting your work, should an emergency situation arise. What is more, if there is a system error or failure, the whole system can be restored easily with a snapshot feature, so you'll just roll back to the condition it was in at a certain moment of time. If you have any problems with loss of data from ZFS and RAID-Z, try Hetman RAID Recovery. It will certainly help you recover accidentally deleted files from ZFS file system or access the data stored in a damaged RAID-Z array. This program will come in handy if your information is gone after errors, formatting, overwriting or other popular scenarios of data loss.

Miller I'm a military police criminal investigator assigned to the provost marshal's office occupation headquarters Tokyo this is case number 3516 it was 1600 hours on the afternoon of May 17th an American named James Clark was calling on a tractive woman named Sonya Borovsky he was a Japanese citizen of white Russian ancestry who lived in the fashionable Shinkuku section of Tokyo Clark was a civilian but not an ordinary one he was attached to a special salvage unit of the Army of Occupation in Japan yes who is it oh just a moment he works so hard let me fix you something to drink well look I didn't come here to drink what do you mean by that I want some questions answered right now why Jimmy darling you're upset what is that I you know what's the matter I've owned you three times today you didn't add so once I want to know why now Jimmy you know how busy you're not explaining that thing now stop talking Jimmy how are you hurting me I'm sorry I'm so much about your son yet when you don't answer my calls when I'm losing I go off my rocket oh I'm sorry too darling now sit down and tell you all about it all about what oh whatever is worrying come on sit down there isn't that better now I will fix you a drink well there is there is something that's been worrying me here is your drink darling just the way you like it is about money isn't it what makes you say that I'm not blind you I've been spending a lot of money on me too much for that all those presents this party don't you worry about me baby all I need is a good break and we're all set those are just words Jimmy you are a civilian technician your salary is not bad but you know and I know that you will never be a rich man and since I happen to be fond of nice thing expensive thing what do you mean there is no reason why you should not be rich Jimmy I know a way for you for that to make all the money we want I look at it's dishonest I don't want to see me don't be silly I would never do anything like that all right what is it I I cannot give you all the details now why not I have to see somebody about it but don't worry it will be all right I would be awfully grateful to your Jimmy darling oh 1710 Clark left the Barofsky woman's apartment and went to his hotel 1730 Sonya Barofsky left her apartment took a rickshaw to the Ginza section in downtown Tokyo on the Ginza she got out headed west down one of the side streets she stopped in front of a small shop that stood between a rundown restaurant a noble Japanese movie theater the shop specialized in fancy oriental teas and other delicacies it was run by a new russian Japanese named Oshimura the Barofsky woman headed the shop went straight to Oshimura's office in the rear of the store oh the beautiful Sonya is here you are late sit down please I am just sampling some tea from the new shipment it is a young high son from Kimon the little tender leaves from the tip with just a trace of Jasmine would you care for some no thank you you know I do not like that stuff you should try to acquire a taste for fine tea in Nippon it is an art have you never seen each annoy you ceremony no matter have you seen our American friend Clark he was with me until a few moments ago good will he cooperate cooperate I'm sure he will comrade good the party will be grateful May 24th or 900 a week later I received orders to report to major Williams the CEO of our military police criminal investigation detachment I met with my partner master sergeant Murray Harris major Williams office and I each he building occupation headquarters here both of you take a look at this matter these markers show special arrest points you'll notice that they're all clustered around the Ginza area Japanese civilians that's right same charge every time illegal possession of US military payment certificates we've run into this before sir true but never like this we had three times as many arrests last week on this charge as we ever had in a week's time before bartenders club operators basket beggars street merchants gashes rickshaw boys all kinds of people all of them with big wads of NPCs Japanese police are helping in every way possible but we know there are plenty more that we don't catch what are those civilians want with military payment certificates only armed forces members and few of our civilians are permitted to use them what about the color changes sir we've been changing the color of that GI money regularly and calling it in for exchange anyone is afraid to turn it in is stuck with well you're right both of us as occupation currency NPCs are good only at certain military establishments we make it tough for anyone caught illegally possessing well then what's the deal sir well as a group in Japan out to round up all the NPCs they can checkups and no checkups sounds communist inspired that method of operation is something like this as best we can figure it the contact members of the group will offer a GI say $125 in Japanese yen for $100 worth of NPCs now there are enough of our boys who don't think twice who sell their NPCs then the contact man takes his cut then the NPCs are passed up the line how can they make any profit sir the whole thing doesn't make sense I will as soon as this outfit gets his hands on NPCs they convert them into a face value amount of US dollars no more checkups then they buy scarce supplies outside of the country with dollars and smuggle them into Japan then they sell them at fancy prices discredit the whole occupation they could clean up as well as make us look ridiculous sir how do they convert the NPCs to dollars well we think they have a front man of some kind an American someone who's entitled to handle NPCs or who draws his pay and so that means all the armed forces stationed around Tokyo not to mention the civilians attached to GI outfits that's right Miller intelligence has prepared a list of all possible suspects and broken it down into sections go to it I looked at the list because as big as a telephone directory we get busy we check out the names in the list asking questions looking into any unusual business deals by Americans no positive results reports came in that the black market was starting to boom by anything you wanted rice to penicillin if you had the money meanwhile the rest of Japanese civilians and GI piled up as routine investigation continued a nightclub operator in the Akuska section was pulled in with three thousand dollars worth of NPCs in his possession two GI's were caught selling NPCs to a Japanese woman the search showed the woman had fifteen hundred dollars worth of NPCs in her possession we rechecked our list including all the American civilians on it we checked fingerprints with the FBI in Washington we questioned all the Japanese we'd arrested then on June 21st it happened we got our first break I got your message Dan what's up we had a call before civilian named James L. Clark engineer technician attached to a salvage unit he was seen making a deposit of nearly five hundred dollars worth of NPCs in his bank account here Clark Clark yeah I remember him we checked him he gets his pay and military payment certificates and deposits nearly all of it but the bank told me his average balance was never more than around fifteen hundred I think you got a bump tip I'm not so sure oh spot anything we've been working the wrong angle Clark's average balance is only fifteen hundred but you should take a look at the transactions through his account as fast as he puts MPCs in he takes them out yeah right checks payable to a bank in San Francisco where he's gotten the count the bank in San Francisco gives him full face value credits in U.S. dollars but why two bank accounts so we can write checks payable in dollars in San Francisco big checks how big he's transferred more than a hundred and fifty thousand dollars from his account here during the past month wow that's pretty good for a civilian technician you're right it's too good you're listening to the proudly we hail production black market money we'll return in just a moment for the second act for you young man with your eyes on the sky and your feet on the ground here's the chance you've been waiting for the army is rapidly expanding its aviation program you can now enlist directly for top jobs in the field of aircraft maintenance now this is an exclusive offer it's open only to graduate aviation repairman and mechanics as an aviation specialist you'll have special advantages take advantage of this unparalleled opportunity in aviation maintenance your army service will make you a better repairman or mechanic and it will prepare you for a brighter future in aviation visit your local recruiting station today find out from the friendly recruiting sergeant how you can better yourself by enlisting in the army directly for the aviation program you're listening to proudly we hail and now we present the second act of black market money 21st 1100 we started to check further on James Clark the civilian technician we took a radio Jeep went into downtown Tokyo we passed the emperor's palace in the imperial hotel pulled up outside the big white building where one of the largest American banks maintains the far east branch went into the manager's office he was a middle-aged man from Los Angeles named Regan he'd been in Tokyo before the war now he'd come back again to his old job we questioned him about Clark more I can tell you gentlemen you have all the information we have about his deposits and withdrawals are you sure there's nothing else anything at all no well yes yes now that you mentioned it there was something it didn't sound very important really I'll tell us anyway sir it's the paper they came in paper yes every deposit made by Clark has been neatly wrapped up in a piece of green paper regular little package do you have any of this paper sir yes a matter of fact I do stiff green paper with little silk threads second here yeah here it is Clark made a deposit this morning 500 mpc's I believe yes sir may I see that green paper yes sure but I don't know what you're going to find out from a blank piece of paper I never can tell sir we might even find out how an ordinary technician gets hold of a hundred and fifty thousand dollars 1130 we checked in with headquarters orders went out to place the suspect James Clark under surveillance 1140 we turned the piece of paper we had gotten from the bank manager over to the laboratory and grabbed a quick lunch at our desks while we waited for the lab report we checked Clark's security file Sonja Borowsky's name was mentioned in it I started to check on her record with the Tokyo police and Sergeant Harris went out and came back at 1300 with the lab report what's the story well paper's not Japanese Dan it's Chinese expensive stuff probably came in from Hong Kong where did Stevens get hold of it and they told me this paper is used to wrap packages of a fancy brand of tea tea yeah Chinese tea special blend there's only one shop in Tokyo that handles small place run by a guy named uh Oshimora near the Ginza funny setup isn't it sure is every morning for a month Clark deposits a bundle of NPCs every morning the bundle is wrapped in that green paper and the paper comes around packages of Chinese tea hmm you suppose Clark has acquired a taste for fancy tea I don't know maybe he's acquired a taste for a lot of fancy things like lean he seems to have the money for it suspect James Clark was picked up for interrogation he refused to answer questions about his financial affairs 1430 he was released an investigator was assigned to follow him Clark doubled back and forth for a few blocks then he headed for the Borowsky woman's apartment you can hear me now turn it off all right now look what you've done you're scratched who cares it was driving what is the matter with you coming in here like

place you think the Borovsky day will hit here can't tell if she does will spot her yeah Oshimora seems to be doing a big tea business in there lots of people going in and out yeah but Oshimora's business isn't necessarily tea hold it a minute what gives let me have the binoculars yeah yeah it's her all right Sonja Borovsky coming down the street toward Oshimora's place yeah I see her now who

over a hundred thousand dollars worth of military payment certificates we checked in with headquarters again Major Williams ordered Harris to tell Clark I was to stick with Sonja Borovsky went to the airline office where she made reservations on the 2015 flight that night to Hong Kong then returned to the tea shop picked up Oshimora and went to her apartment it was now nearly 1600 I contacted

1640 he went inside I waited downstairs for Harris I tried to get here as quick as I could got tied up in that bridge traffic oh where's Clark upstairs came in about five minutes ago eh shall we make the arrest not yet I want to check again with headquarters before we take them something doing right the Borovsky woman stopped into the airline office to make reservations on the flight tonight to

Clark you have made the final deposit and uh transfer the funds yes the money's on its way to join the rest and sentences no that is wonderful Jimmy darling we're rich yes uh now we can conclude our business agreement and you will write me a check for the full amount three hundred thousand dollars I believe and with the dollars we can buy more of the materials for our business enterprise here when do I get my share Arshamura have you forgotten our agreement you will be paid in Hong Kong as soon as we sell the goods bought with these dollars oh this is no time to worry about such things Jimmy let me fix you something to drink why can't I have my share right now that is impossible mr. Clark that money represents an investment well maybe so but don't forget that it's in my name in the states I'm the only one who can touch it that is true mr. Clark but if you try to keep that money for yourself the military police will be informed of all the details concerning your part in this matter you wouldn't you'd only lose the money that is very true but uh when you gamble for a high stick it is uh as you say all or nothing yes let us think of pleasant thoughts mr. Clark there will be plenty for everyone your share of the money it is only one hundred thousand dollars now and when we buy goods with those dollars and sell them to those who will meet our price your money will increase many times perhaps to half a million think of it Jimmy half a million dollars give you the check Jimmy half a million there is one desk drawer I will get here it is use this table mr.

This study found that a video acceptance facilitating intervention, AFI, was not effective at increasing acceptance of smart sensing among adults. The study also found that performance expectancy, trust, and social influence were key determinants of acceptance.

Hey there friends, how's it going? My name is Kevin and today we're going to be playing a little bit of Half-Life Alyx. I've already played it. I just finished recording the gameplay. I absolutely love it. It's insane. I just love how- You know what? Nevermind. I'm not gonna ramble for once. Let's get into the game. All right.  I really have to fix my VR so that I'm not faced the wrong way every time I start though. This game is awesome. I'm calling it now. I should probably be looking at the world they've set up for a cool intro instead of just playing with a radio But that's just me as a person. Oh, pigeon! Come here.  I'm playing this game wrong and it's like two seconds in. Oh, there's pedestrians. Die, die. All right, you know what?   Sorry, I have anger issues. Who's on the other end? I hope it's my therapist because I need one. This is amazing. There we go. If anyone breaks in, they get a nice message now. You like that? Can I draw on this? My green screen's in the way. Drawing on the monitors. Gonna give him a little mustache. Oh my god, this is spooky. I've got a pen I will draw on you. Is anyone there? Oh good. Light outside. I'm the danger when I'm brave. Remember when I get hit star for that pigeon? Run away. That's not a pigeon. I'll write on you if you don't go away The hand and everything. Get back. Who are you little fella? I can't write on you. I just want to write on things. Oh, yes All right, so far screens are about 50-50. Windows the same Whiteboards are a hundred percent. That's my review so far. Oh wait, am I a pervert in this game? This game's cool. Where's the zoom on this thing? I gotta Like look right in their window. I'm only like two minutes in. I've mainly just harassed the pigeon and wrote on stuff And I'm already like this is the most immersive VR game I've ever played. You know It's good when you keep getting lost in your room and you have to take it off the check where you've gone People on the other side of a window. I want to write a message to them I know it's backwards for them, but I'm not smart or fast enough to write this the right way for them That's what I think of you saying stay safe which from their angle would say koof. Yeah Pigeon wait, hold on. I got to have something here to troll at you.   I love how you pick stuff up in this game. It's the most realistic thing I've tried it's even more realistic than bone works. I think which is an achievement Plus you can write on more stuff in this game and harass more pigeons get back. That's right. I'm dangerous I have to make a choice don't want to progress the story or keep my chair. Whoa. I just did both I have no idea how where the hell am I going? Uh-oh get back. Who would win three armed men or one with a chair He keeps just pushing me back I'm ruining the story. Wait, isn't that my dad dad take a seat. Wait. No, he's got lumbago I'll even sit down. That's it Okay, well I did draw a gun to be fair. It may have been a finger gun, but still I should have never drawn those finger guns. All right. It's time to end it all I'll draw the finger gun on myself. I'll do it. I tell you if you don't let me out of this No screw the man. I'll do whatever I want Oh Jesus Christ.  Yeah, this definitely isn't a pigeon. They don't have accents like this. They have new york accents. Can I go out of here? Okay, good. All right. Let's get out of here. I need some weapons Oh, I don't know my own strength sometimes. Oh, I want to go Oh, I broke it. I go on the slide at least. No, this is sad. Oh, I can play with this though against myself That's no fun. I'd probably still lose Oh, sweet. Jesus. I don't have my markers anymore. Get out of here. What is this? Oh Okay, let's hi. Oh, this looks expensive Anyway, hello. Yes. What do you need me for my plan to get them back? Great. This is what I think of your plan He's just refusing to acknowledge it. He knows that's just feeding into me. Do not eat. Oh, I want to eat it Oh, it's gonna be a good Christmas after all. It's dinner time. Okay, that's you This represents me to be fair.  Oh god. What did I just do? I keep opening the menu by accident Okay, these are gravity gloves apparently. I'm ready to gravity those pigeons don't stand a chance now to bring it in Oh, oh Excellent. No, it wasn't quite excellent now. You're gonna need a gun. Don't worry. It's unloaded Jesus dude, what's the matter with you returning fire? Oh wait now. It's actually empty. Give me ammo Oh, I hope there's no one in there All right pigeons come at me now. I'm armed and dangerous. Do you think that can stop me? Not a chance Yeah, I hope you didn't have the key Wait, who closed the head? Let me out. Did the train stop? Yes. Wait, what is going on?  It doesn't do anything. All right. Let me get back to the objective Where am I going? Oh, that doesn't look good. The pigeons have been here already. I want them to come at me Look, I've got this hard hat and everything so they don't have a chance. What were you doing, buddy? You're probably up to no good. It might be good that you died All right. I might be being a bit disrespectful How hard is this thing on come off? Oh look at those nails though. I think he's going for a world record All right. Let's see if bullets go through things. Nope. All right. It was a good experiment Anyway, I do have a hard hat on so I'm feeling like I should be doing experiments All right, it doesn't look like I should be here But in my experience if I have a hard hat on I can get in anywhere.  A multi-tool? All right. Where are we going with this?  This is awesome This hard hat is really soothing me. It makes me feel smart. This doesn't look safe Are we sure this is going to help me? All right. I'm just not going to look I've had enough needles in me to be called a pincushion, but I still don't like looking when they actually do it The hell was that? Nah, probably just the wind God damn it. Sorry. It wasn't the brush that scared me. It was the idea of cleaning Got a lot of locks around here, isn't there? I've never felt so American. Just shooting everything My hat! You bastard! Just immediately open fire. No one takes my hat. Hats have a really good purpose though Like if they can defend you from them. Here take this Idiot. Yeah, that's not going to be very tasty dude. Yeah, I didn't think so. Oh dear.  Does that work? Oh, no, no. You get stuck. My hat! No, no, no! My hat! It's not my hat.  I'm so sad.  No change from the norm at least though. Come on out No need for you to self-isolate. You're already infected. Come on. What do you got there, huh?  Oh and I'll run these doors. Well, I'll take care of this with my screwdriver What do I do? Should I just climb in the window? Maybe this box? Oh come on If that weird thing on the ceiling could do what I can do it. He lifted it like it was nothing See, it looks fine Okay, it doesn't look so fine. I have no idea what I'm doing I'm in way over my head. Can we need that? Whatever that is.  I don't understand Oh, I didn't know anyone was watching Well now I look like a psychopath that guy was watching me that rat was bothering no one Okay, I got to figure out what this thing does. It's got to be something to do with this Okay, there we go. And we need to link it up with these I'm not sure what I did. I apologize if I broke that I don't know if he just didn't explain this or I wasn't listening Okay, so avoid the red and then go for the blue. I assume Did I do it? I think I did a thing Yes, I did it. The hell is that thing? Oh my god, there's a rat in there.  Okay, did I link up your weird rat machine? Got to be honest with you weird technology to open the door Like at some point you're gonna run out of rats I don't feel like I should be going in here without a heart hat.  I've kind of want to shoot it red means good Oh god, since when is red stuff flammable?  You keep doing that without a heart hat trust me Okay, that's dangerous. There's nothing in it. Like if something were to I don't know explode and we might need a fire extinguisher Can I just feed this thing? Aha, there we go. Now. Can I just get around this? Probably should have killed them first. What oh well. Yep, probably should have killed them first I really like the gravity grabber thingy. It's it's really cool. It works really well I don't like these things. They steal my hat hat. I knew there'd be a hat in here. Did I get it? No, that didn't land on my head at all. That's not a hat. Where's my hat? Where is it? Okay, there we go Yes, hat. Okay, this looks dangerous. Hold on Oh, yeah, take that off. Hold on. Uh, wait, I'm gonna do an action. Oh, I was gonna shoot it But I guess that works too. I'm just not as involved Just walk straight through the reigning body parts doesn't matter have a hat on Oh, yes the reign of success sweet jesus. There's a lot more enemies than there used to be now come out Oh, okay Not so effective. Just stay still for me, please. Thank you. You see he died nicely Is that one crying? No, don't go hide. That one's just waiting on a train or something slapped them out of the way There you go. Just a gentle slap ought to do it.  I don't understand Do I need to somehow get this through them all or do I try and get that blue thing lined up with this? There we go. I got all of them. Is that gonna do it? Okay. I think that accomplished whatever I'm trying to accomplish I should really learn to listen more. All right. It's telling me to give up my gun I'm willing to set violence aside. We are at peace now. Oh, yes stand still perfect. Yeah fire. Oh, no I've alerted him.  Okay. I think this is going a bit beyond hard hat. This looks really dangerous I don't think even a hard hat can protect me now.   I think I might go upstairs and do a little outro I don't even know where you are here. So this isn't the best place for me to do an outro I'm here. I'm upstairs. I'm upstairs now I'm out of vr and it feels less real for some reason that game was just so immersive But yeah, I hope you guys enjoyed the video I know I enjoy playing it if you want to see more do let me know I feel like it would be a perfect game to like live stream if I could set that up I don't know. I feel like I want to live stream a ton of games, but I never get around to it But yeah, I hope you enjoyed I appreciate you watching as always folks and I hope to see you next time. Bye for now
