Generating graphs packed with paths is joined between Philip, Verna, and Matthias, Ho, Anderson, and Matthias, we'll give the talk. Thank you. Thank you for the introduction. So the talk is divided into five sections. So first, we're going to have some motivation about what we're trying to do, and some of the civil folklore about linear cryptanalysis. Then we are going to rephrase linear cryptanalysis as a set of graph problems, and then we're going to look at some heuristics for finding good sub-graphs and why this is of interest for SPNs. And then we're going to look at some plots and results, and then lastly, some future work. So first some motivation. So since the 90s, we have been knowing about linear and differential distinguishes. And generally, when you suggest a new design, one of the things that you have to argue about is provide some sort of argument against your resilience to linear and differential cryptanalysis. And of course, what is of interest is to determine the optimal parameters of these distinguishes, as well as the expected power of our distinguishes over the key space. So in this presentation, we'll primarily focus on linear cryptanalysis, both because of the session, and also because the differential case is largely analogous for the work presented here. So for an hour-round cipher, iterated cipher, we have this notion of a trail, which defines approximations over every round function. And the idea is that we can calculate the correlation of the approximation over every round function efficiently because it decomposes into relatively small and simple non-linear components for which we can enumerate the full domain. And then we have this notion of a correlation contribution for a trail, which is simply the product of the correlations over the approximations over all the rounds. And then we can describe the correlation for an approximation between alpha and beta over the entire cipher, simply as the sum of correlation contributions over all the trails under suitable assumptions. And then for key alternating ciphers, we generally assume that the analysis becomes, if you consider the square correlation, then it becomes independent of the key. It essentially becomes a sign. And then we have this notion of an ELP, which will be the expected correlation amplitude over for our extinguisher, and we can estimate, again, suitable assumptions. This is the sum of the square correlations of trails. And then what happens at practice is that we sum over some smallest subset, calligraphic U. Often this calligraphic U is merely a singleton, in which case you're assuming that there is a single dominant trail. So the idea is that we will sum over the dominant terms. We will consider the dominant terms of the summation, and they will give us a good estimate for the entire sum. But of course, the performance of a single trail, and particularly even any small set of trails, is not necessarily a good indication about your design susceptibility to linear and differential cryptanalysis. And this is the problem that we're trying to mitigate. And generally current methods for considering multiple trails of a whole are linear in the number of trails. And then for the signs, which have a very large number of good trails, this is suboptimal. So we would like to get some sublinearity, which is the goal of this work. And to get into this frame of mind, we are going to rephrase linear cryptanalysis as a graph problem. So the graph is going to be what we call a multistage graph. So in this case, we have a cipher of three rounds. And it's a directed graph here going from left to right, but I omit the arrows. And the vertices are parodies for linear cryptanalysis, and they're similar for differential. And the edges then naturally become the approximations of the round functions. And the length of the edge is the squared correlation of the approximation of the round function between the source and the destination of the edge. Then if we consider with this notation, then if we consider the length multiplicatively, then paths through the graph becomes trails. And the length of a path becomes the squared correlation contribution of the particular trail. And with this, we define the notion of a weight of the graph between an alpha and a beta as the input and output nodes. And this corresponds to the whole, which is the sum over the lengths of every path between alpha and beta. One very simple observation here is that you can calculate this in linear time over the number of edges, basically using bottom-up memorization. So you start by calculating the hole between any alpha and any u-node, which is trivial in this case. And then we can calculate the hole between any alpha and any v-node by, at any v-node, calculating a weighted sum of the holes between the alpha and the u-nodes. And then we progress similarly for the beta nodes, again calculating a weighted sum over the holes between the alpha nodes and the v-nodes. Also note that we can calculate, we get for free the weight between alpha and any beta node. So we don't need to consider any pair. But of course, this is all nice and fine, but the problem here is that the graph is part too large, right? So if we did naively define the graph as this, sure, the algorithm runs in linear time, but the graph is exponential size, so let's use. So the question is, can we find some suitable soft graphs that contain, in a sense, most of the good trails? And of course, the observation here is that we are not looking for good trails necessarily. We're looking at the more general problem of finding these good graphs, i.e. we want the maximization of the weight between any alpha-beta pair to be large. And for this, we have devised some heuristics. And in this case, we're going to be focusing primarily on SPNs, for which we have the best heuristics. So the overall method will be that we'll pick some sort of disjoint families of edges, which we'll describe. Then we'll prune the families using an approximation of the graph defined by these edges. And then finally, we'll expand these families to a full graph. And then at the end, we'll do some cleanup work on the graph. So one immediate and easy observation is that if we have any edge of length zero, we can just remove it. This corresponds to a trail with length zero, and it doesn't contribute to the whole. And then once we've removed it, we can remove any vertex that doesn't have a predecessor or successor, because no path can traverse it. But this still doesn't get us far enough. So now describing these families of edges, so this is probably best described by giving an example. So consider a 16-bit SPN, a small toy cipher, with four identical S-boxes. Then if we have the following two approximations over the S-box, with the following square correlations. So three goes to D with correlation two to the minus two, and seven goes to four with the square correlation two to the minus two. Then if we have the S-box pattern, which we call it, this will be a family. You want to have one of the families S1 to 1.2 to the minus two, 1.2 to the minus two. This corresponds to every approximation over the S-boxes, which have this particular pattern of square correlations. So in particular, the first and the third S-box must be inactive. And the second and the last S-box is basically any combination of the approximations above. And then we also naturally have the projection onto the first and the second coordinate, which corresponds to the set of all input parities and set of all output parities for the family. Then if we have some set of families, so we have some set of S-box patterns, then we can consider the graph defined by this set in a natural way, by simply just expanding every member of the set, these forms are edges, and then our vertices is just the union of the projections. So suppose we have some set of S-box patterns defining this soft graph that is of our interest, then we can immediately serve that for any intermediate stage in the graph, so any node that is not an input and an output node. If V does not lie in the set of both, if V does not lie both in the set of input and output parities of the expansion of all families, then it's immediately pruned because it can't have a predecessor or successor. Our problem now is that, so we've defined these families, we can keep the description of the families in memory, but the expansion we cannot possibly keep in memory. So the idea will be that can we somehow prune on these families before expanding them, so that we have less families to expand and we can manage the graph. And the overall approach and the more details in the paper is that we generate an approximation of the graph by applying a compression function very, very like differential, truncated to differentials in such a way that if there is an edge in the original graph and it's a path between two nodes in the original graph, then there is also an edge in the truncated graph but not necessarily the converse. And then our algorithm is basically iteratively refining the compression until you reach the trivial case. So we start by generating some set of patterns using a heuristic. We have a generic heuristic but if you have some cypher specific knowledge you could apply this. And then we pick a compression factor. Then we generate this truncated graph by applying the compression on every vertex when we expand the members of the set and then prune on the truncated graph. Then we remove any family, any S-box set, any S-box pattern for which all members of the expanded S-box pattern are not in the truncated graph because if a member is not in the truncated graph it cannot be in the full graph either. The truncated graph is sort of strictly more connected. And then we refine the compression until we get to the trivial case. And then we expand the graph. Notice here that in a sense this procedure is lossless. So you're not removing something that could otherwise have created additional paths. Once you've fixed your set of patterns the graph that you will get out in the end will have the same set of paths through the cypher. So suppose we have this following graph at the end. Then we observe the problem and this is basically that if we apply now pruning to the intermediate rounds at the end after expansion then we will lose a large part of a search space. And the way that we heuristically avoid this for SPNs is that we add some vertices that are not in the set of the expanded families that are optimal for the vertices that would otherwise be pruned. So they input and output vertices. See if we can do this here and here. Here and here that would otherwise be pruned. Then we add optimal input and output vertices to ensure that they're not. Okay. Then we can take a look at some plots and results. So we've implemented this heuristic in a publicly available tool that we call cryptograph. And for SPNs it's very simple to use. It's essentially file and forget. You give it a linear layer, give it a non-linear layer and it can start giving you analysis. So of course one thing you can do once you've found this cryptograph is that you can plot it at least for small parameters so that you can actually look at it with your eyes. And we hope that this will be of use to the cypher designers so that you can then visualize how the whole looks. So here's a plot for present. So you immediately see basically the Okuma observation that you have this huge amount of trails because you have this level of freedom in your choice of approximations over the round functions. In contrast, here's a plot for gift which is essentially a present-like cypher with this specially crafted bogey permutation that is designed to avoid exactly this observation that is found in Okuma. That you have this very large number of Hemingway 1 trails that are all roughly equally good. So in particular for a person, you cannot simply upper bound the square correlation of any particular trail and take that as indicative of your cypher's susceptibility to linear cryptanalysis because there is this very strong hold effect. So we have applied the technique to 17 different cypher's for both linear and differential cryptanalysis. And I want to highlight the following results. So we have four present-like designs. And for the present-like designs, we generally find a very, very large number of trails. So just as an extreme example for Puffman, we find actually the hold that we end up considering between our approximations contains 2 to the 112 trails. And for present-like designs, we generally see about 2 to the 60. So for present, we also see 2 to the 60 which is also not feasible to do if you would have to enumerate them with linear time. So we improved the analysis of present by essentially considering a vast number of trails at really no additional time. And then for rectangle, we also improved the hull analysis that is found in the original design work by considering a few hundred thousand trails. And lastly, some points of future work. So we would like to add support for ARX cypher's. We need some good heuristics for ARX cypher's. The current heuristics obviously don't port. And it's not immediately obvious how to do this. And we would also like to have some better heuristics for fast network. We do have support for fast network, but we would like to have some less generic heuristics. Yes, that's the end of my talk. Question from Matthias. Thanks for the talk. You said that for the tool, you intended to be helpful for designers. So if I am now designing a new SPN, what do I have to do to apply this tool to my new design? So for SPNs, it's really, really simple. You simply supply the S-boxes, so you can have different S-boxes in the same line, but we currently only for technical reasons don't support different S-boxes in different runs. But you give it the S-boxes. You give it the linear layer. You implement this in a Rust function. And then even if you also give us the key schedule, we can also generate an approximation of the correlation distribution over the key space. Because this method also gives easily rise to a way to quickly enumerate the correlation over the key space. You basically just re-weight the graph according to the particular expanded key that you get from running the key schedule. So for SPNs, it's really simple to apply. Okay, nice. Thanks. So does your tools also support the partial S-box layers like low MC? I think we do. I'm not particularly... I'm not super sure about that, actually. Okay. Let me see. I don't... The question is whether we've added that subsequently to this because we've kept working on the tool. I also have a question. Maybe I missed that part, but do you have a bound of the results and the actual situation? Could you rephrase that? Yeah. So do you have a bound between the result you find and the actual situation? Or is that error? So the results that we find, right? So if you give me these S-box families, then I will consider every trail that lies in this expansion. So if you give me, say, all the Hemingway 1 approximations over the Hemingway 1 parodies over the S-box, say, for present, then I can give you the result for the whole over every trail that lies in this, right? So in a sense, it's more robust. I see. So the heuristic step is choosing this calligraphic piece set of patterns. I don't know if this is... Did I answer your question? Yep. Okay. Any more questions? If no, let's thank Matthias and all other speakers in the session.


Let's just do a sit rep of where we are what I want to do This is probably when I'm gonna start my YouTube. Hi YouTube We are here Let's put a marker here. Oh, that's that'll make it easy stream markers YouTube starts Oh, that's gonna make it real easy, okay, I just found the useful markers chat Hi YouTube So here's where we are. I finally got the ability to grow blast nuts last night so That's good. That's very good. I finally got I get my login reward Also, I am going to be eventually probably today. I'm gonna first farm nerda gante For the hammer I'm gonna be using when I switch to hammer. I want to try hammer And that requires me to get a nerda gante plate Sure when I'm talking about Nerda gante plate as well as Some other stuff just down here. I need a regrowth plate. I need one more of those 92 tails Which may be more challenging than the sounds and then I can get the nerda gante hammer Which looks kind of awesome by the way. I don't think I don't think you saw it It looks pretty awesome That's what it looks like if I preview it see I wish you could is there a way to There we go Look at that man. There's just spikes all over. It looks like a great hammer. Yeah, it's very spiky It's a good hammer, so I'm gonna be working on getting that today But I want to take care of some of these Some of these optional quests and side quests that I have to do that unlock various things and the first one I'm gonna work on is the I want a harvest box upgrade and I was working on this yesterday in a day day before that too It's taking a long time. I need a torrent sack From jigger murder jigger jigger jigger burger Whatever's name is and it's called your story solution. I need a torrent sack, which will give me a harvest box upgrade. I want that Hey Colin welcome man How you doing? You can really poke an eye out is true. It's true So I don't have any high-level investigations For this guy. I've been working my way up. I've gotten to like level five. I think So, but it's a slow process Yeah juror juror juror to those this is the guy I got a hunt So I've gotten them up to five star I think if I get them up to six and think he'll stop drop he'll start dropping the torrent sack But right now he doesn't Okay, so I'm going to Start with that so let's go and change our loadout here to cluster guy We're also going to change our weapon I don't think I'm yeah, I am rocking. Okay the Magda Jermidus You manage loadouts here cool. Oh, I got the ghillie mantle. Let's take this off I was doing some I was doing some egg deliveries So how do you use the ghillie? Okay, and so I'm going to do this five star which is two monster kills which is kind of annoying and Let me double-check see if there's some new investigations that I can add for juror juror His name is the hardest to remember No If I see a hard mission Obviously a heart mission with high-level mission for him. I'm gonna jump that if anybody else has a high-level one Please let me know and join me and let me let me bum off your mission your investigation because I don't have one Slowly working up though. That's the three-star Also, I was hoping to get one in from this guy Just like randomly, but I haven't got one yet. So like there's just got high quality pelts Yeah, I Kind of I had it. I requested two trading items and material items because I needed money Because I was converting points to money, but now I don't need that See, he's giving me toxin sacks poison sacks. So it's not like really really high-level stuff And I'm kind of low on points. So I'm kind of holding off on that Also, I got my my cat expeditions. I have a six star and a two bronze that's in one go, dude Can you join? I Would love to do that. I'm not you. Oh I switched to the ladybug set for a paralyze on Frank But I don't have the weapon yet. That's something else. I'm on the farm They're still going if you could join we could do that. That'd be great the session ID is this Let's hope we don't have any people trouble joining. Okay. You're you're in here. I will join your quest Let's do this. I should have used a ticket I am ready. Oh, I am ready. I'm ready Why does she keep saying that food with me Yeah, everything looks to be in order. Yeah, I think my crafts I need to take out that poison and change it to sticky No blivered On my load out. Okay. Let's get out of here. It's fine Let's find some dudes can find a way out. Oh, hi Careful black Diablos is right at the door. I should be getting points. What is this? That's black Diablos. I want points for the other guy She says that because you haven't been to that spot before and don't have a camp there But I was able to pick that camp. Oh because somebody else And my group had it I was able to go there. Okay. I didn't know that does that okay I'll check that that liveries when I get back. I will check that. Maybe that's why it was highlighted like that, huh? I don't have any sticky. Why not? gosh, I Only had a mask to make it. I don't know why I don't have sticky chat Stickies love stickies like all I got is Pierce So I think my loadout got messed up It doesn't make sense because I was just using it last night. I get some spamming Pierce and my sticky three in my Clusters are gone too. Okay. I can do a cluster now. I Can't do sticky anymore. I don't know why it's weird Reload this first Of course he moves as soon as I do it. Oh first fight of the day I'm finding out all kinds of stuff wrong with my my loadout So whoops We're getting wrecked chat. He doesn't like you.  You best watch this Sorry guys. I just brought crap ammo Could go back and To the base and Probably just use normal three probably better Sad faces were had that day Chad as he missed another another cluster bomb This is a difficult fight for a gumbo user Not real not to me. It's actually pretty freaking easy Even easier if you have the right ammo Is he right? Am I right? I was blocking that. That's okay.  Are you growing them? because I'm trying to Get a good stash of flash flies and I was farming them. I was like this is slow I mean I was going out and capturing them. I was like, this is pretty slow. This is pretty slow. Yeah, this is pretty slow and I was like it's gotta be a better way But I haven't gotten the the thing in my garden yet to grow them I've gone through almost all my pierce and out them a range Let's burn this normal three About what I can do So where is this weak spot? Is it the head? I gotta look at the the research findings Looks like it's the head Did I build a gathering set? What does that mean? I have I have I think a single decoration For possibly getting an extra gathering Thing on my gumbo. I didn't know. Can you do that with armor too? Can you do that with armor? I didn't know you could do that with armor Maybe that should be a priority Yeah, maybe that should be a priority. I should get into building the armor set for gathering The only thing I have is a decoration.  Yes More please Okay, do you know of any off-hand ultima?  Oh I didn't know that So how do you coordinate that? I didn't even know that. Hey, what about stickies do stickies knock you over? Oh, what is 40 there? I don't have any stickies right now, but that's like my major thing with this Maybe I should use my my bow gun. I mean my bone one I'm in groups I don't use cluster that much in that one.  I'm just like the anti melee guy All these years. I've been like making you guys live miserable. I don't know why ever No, I wrote right into it. That was dumb. I'm sorry guys. This should have been over by now Father brought the right ammo There's the face Is that my palico paralyzing is that you guys? So I think my palico could paralyze yet till I get the weapon I maybe you guys this palico have paralyzed All right, can we I don't have any capture stuff. Do I? No, I can't capture him He's got a skull. So he's about dead Geez, what are you doing? What I'm sorry I feel bad man because that that was I even looked at my loadout and I thought I had everything No, we don't have to capture. We don't have to capture it. Just just kill him If somebody already had it then we can capture him and get extra loot, but That's another thing I want to do. I want to have capture stuff in my inventory The loot's Just kill him.  I have one That's like the only thing I don't like about heavy bone gun, man It's just that the ammo up ammo upkeep is kind of Obnoxious It is obnoxious. It's like the amount of ammo and ammo materials you have to have all the time That's probably why these people say is not good for beginners because That stuff is like a maintenance nightmare. You spend half your time farming Nuts Pretty much And I mean how many other classes have to deal with I guess the melee classes you guys have to farm like um You probably have to farm a lot of uh No flash stuff and trap stuff Okay, I don't have any more uh, look at the square. I put a barrel in here Let's go man You post a link. Okay. Thanks, man Oh by a telemanual can be used. It's a good timing because I need it. I think he likes me Nobody's here Yeah Cluster to the rescue chat Yeah, this is high maintenance, man That's why I'm looking forward to uh To try and out hammer And then I mean once I get my garden going and everything and get those those nuts growing um I think the heavy bow going to be a lot easier. Come on. Give me the freaking torrent sack I need a torrent sack. I hope it drops it Yeah, uh, do you remember what quest you did dbr in to get that unlocked? Because I don't have the bugs yet. I just got the bullets yesterday. I just got the nuts yesterday But I haven't gotten the um Thank you. There we got it. Okay We got a chat That took a long time because I I just didn't have the right level investigation for him New optional quests are available And that coffee's good. I can slurp that whole thing now All right, let's let's pull for the giveaway We got seven people entered And the winner is uh Uh scotty boy scotty boy Scotty boy, congratulations. Sorry. Is he subbed? That boy of scotties. Are you subbed in my stream already? Let's find out I was gonna do twitter.com such one. Where's that tv slash buona? Get the sub scotty boy Yep, he's not subbed He is now Uh Congratulations, man. Thanks for that. Uh Thanks for that Thanks for being here You're now sub sir. Okay Do I have the harvest box? I do But I don't have the flies yet This is what I have available Like I just got the blast nuts from doing a optional quest the other day, but I don't have the flash bugs You see I got the dragon straight nuts of blast nuts Um, which I both need latch berries for slight uh slice ammo. I'm sorry pierce ammo slash berries But I need to get more of these boxes too But I don't have I don't have the the the flash bugs yet Yeah, I'll do that. I apparently I didn't know any better Let me get this build from you this gathering build That's gonna take some work. That's going to take some work See I didn't do them as they showed up.  What's going on? Am I the gunpowder? Is that it? Cluster buster Oh, am I the nuts I'm either blast nuts. I think Yeah, the ones I'm growing. I think I'm out of those I think the extra stuff was four star. I finished that though


My name is Dr. Rohit Bharni, Junior Resident 3 from Bharati Vidyapit, Sangli, presenting author, Dr. Rohit Bharni, corresponding author, Dr. Vijay Kumar Esmane, affiliation of presenting author, Junior Resident 3, affiliations of corresponding author, Professor, Department of Related Diagnosis, Institution, Bharati Vidyapit, D.M.2B University, Medical College and Hospital, Sangli. The topic of my presentation is ultrasonographic findings in patients with ocular complaints. Aim of the presentation is to study the ultrasonographic findings in patients referred with ocular complaints. Objective to describe the USG features in various types of ocular diseases, to evaluate the role of ocular sonography and color Doppler in various ocular conditions. And comparison of USG findings in post-ocular to patients in selected cases. Introduction. Patients presenting with ocular complaints must undergo detailed ocular evaluation conventional methods which have been used for many years for evaluating the eye. Have included slit lamp and fundoscopy examination. These procedures can be conducted in the outpatient clinic without much discomfort of to the patients. Also the diagnostic accuracy of these investigations is fairly high. However these investigations require that the media should be non-opic. It is for this reason that these traditional investigations lose their importance if the clinicians wants to want to diagnose patients with an opaque cornea and cataract and the other pathologies which involve the retina and corad membrane. Image modalities such as CT and MRI have been used with high accuracy. So as to investigate the various pathologies of the orbit and group the CT scan has a very high exposure to radiation while MRI scan is associated with prohibitive costs. As a result, previously published literature has demonstrated the increasing use of ultrasound in diagnosing ocular diseases. Ultrasonography is not only cheap but also does not expose the patient to high doses of radiation. The investigation can be conducted with the help of portable machine which increases the accessibility of this modality and it can be conducted non-invasive layer as well. Materials and method, study design, it is a descriptive observation study, study setting, department of radiative diagnosis Bharti Vidyapit Medical College and Hospital Sangli, study population patient referred from the department of radiative diagnosis Bharti Hospital. Sangli for B scan with ocular complaints and fulfilling all these criteria of inclusion criteria. All cases with clinical suspicion of ocular diseases were eligible for the study admitting to Bharti Hospital Sangli where USG scan was used as modality aiding in evaluating the case exclusion criteria. Patient with active ocular surface infection, patient with either high risk or presents with extrusion of ocular contents, patients with orbital trauma results. In this presentation, 100 patients were included of which 10 patients had both eye affected so total of 110 eyes were studied. Average age was 57.37 plus minus 15.9 years ranging from two years to 86 years. It is observed that the 58% of the patients were in the age group of 51 to 70 years. Then there were 22% patients in the age group of 31 to 50 years. Based on USG the most common diagnosis formed was cataract which was presented in 30.3% of the involved eye. The next common diagnosis was that of retinal detachment which was presented in 17.3% of the involved eyes. Vitreous immerage was diagnosed in 11.8% of these involved eyes. Cataract with posterior vitreous detachment was diagnosed in 7% cases. Less common diagnosis were made that of a fechia in 6.4% dislocated slash subluxated lens in 5.5% retinal detachment with vitreous immerage in 3.6% only posterior vitreous detachment in 3.6% coroidal detachment in 2.7% and retinosis in 1.8%. There was one case each with old retinal detachment with cyst, optic glioma, posterior cephaloma, ID plus subretinal hemorrhage, thysis bulbide, uvitis with vitreous immerage with nemascularization glaucoma. There were 4 patients 3.6% who had no abnormalities detected on USGs. Discussion. The present observational study was carried out among patients who were referred with a clinical suspicion of ocular pathology to the department of red diagnosis for undergoing ocular B scan ultrasonography. The present study was conducted for December 2018 till May 2020 during which they underwent B scan USG based on the ocular USG findings of lens, vitreous membrane, coroid, retina and optic nerve were noted for all cases and a diagnosis was done. We included 100 patients in the present study of which 10 patients had both eye affected. So a total of 110 eyes were studied. In our study, mean age of the patients was 56.37 plus minus 15.9 years and 58% of the patients were in the age group of 51 to 70 years. Also males and females were equally distributed. The most common presenting complaint was diminished vision 99%. There were 9 cases with pain and 5 cases with each with redness of eye and eye discharge. There was no history of surgery trauma or trauma in 78% of the cases of the result of the rest 11% as had a history of trauma and 10% were previously operated for cataract and one case for retinal detachment. In our study, 28% were diabetics, 18% hypertensive and 2% were both diabetic and hypertensive. The discussion points include actual length of the affected eye, USG findings of the lens in affected eye, USG finding of the posterior segment of the affected eye, USG finding of retina, USG finding of the coroid, USG finding of the optic nerve, USG diagnosis in the affected eye, accuracy of USG diagnosis based on comparison of USG findings in postoperative patients in selected cases. These are the following references. We took 50 references out of 50 references. These are the top 8 references in our study.


It's Tuesday, I'm on my way to lectures, I've got lectures 9 till 5 and I think it's evidence-based practice all day so I'm hoping it's going to be a really fun day and it's not going to be a little bit long, like the research one, so let's see what today brings. I've got a new student at the university, hey Mr. Doc, enjoying the course so far, great. Today is Thursday, I'm a little bit late of vlogging, I have another chance to do any vlogs this week, I'm really sorry so I'm going to just give you the low down of what's happened so far, just briefly, I'm not going to go into too much detail because it's probably a little bit boring just watching someone talk so let's get to it. So as you know I was back at uni on Tuesday and we had a day of research, again I just, I can't get on with it, I just, I'm really sorry and I feel guilty for saying this but sitting and listening to someone talk about research bores me to tears and I just want to sleep and I feel bad because it's not the lecturers fault, it's not the university's fault, we have to be taught this, we have to do this as nurses, it's just not something that stimulates my brain I'm a hands-on person, I don't like to just sit and listen, I'd rather be doing it than nothing but saying that, pushing that aside, the lectures, the lectures we had, we had four hours of research and they were really informative so we went through the step-by-step tools and how to research effectively and work out whether evidence-based practice article is actually a genuine really good article or if it's a bit meh choose something else, that was really good to actually go through that so it's been really good for our poster presentation, we know what we're going to do now but Tuesday was just a really sleepy day for me, I wanted to go home and I wanted to sleep, I just, yeah that's all I can say about Tuesday, I'm really sorry, well actually in the morning we had nursing in care so we were talking all about the way that we care for patients, holistically, spiritually, all of that so that was a really interesting lecture, I love doing that sort of thing, it's just a shame that I don't enjoy research but we can't love everything about nursing, there are going to be things that you come across that you don't enjoy so it's not for everybody, there's no harm in that and we shouldn't feel guilty but yeah I do feel guilty because I think I should love everything but I don't so yeah you'll find out if you haven't done your research part whether you enjoy it or not because everyone's unique, everyone's individual and some students absolutely love the research, they really found them interesting and then Wednesday I had the day off so I chilled for the morning, my partner was off so we spent the day together, I had to go back to the hairdressers and have my hair corrected and toned again which I've had done so it does sit nicer now, it blends in a lot better than it did before so I'm really happy with it now, getting used to the colour, I'm happy with the colour overall, it blends in nicely now so I'm chuffed with that and then today, so today we had a day of lectures, so our first lecture of the day was we had two newly qualified nurses come in and speak to us all about general practice nursing which you all know I love general practice nursing, I was so chuffed that they were coming in to promote general practice nursing, it was lovely to see and I was just chuffed, I just sat there in amazement because I just love it and I knew, I understood where they were coming from and the things they were saying about patients and the interaction that you get and it's just amazing, it just reminded me how much I love general practicing so and then we had a break and then we come back and we had public health with Lee who's fantastic, he's so good, he's so knowledgeable, he's interactive with us all, he keeps us all awake, he puts on a quiz to get us more interactive, get our brains working a little bit, keep us awake, he's just fabulous, he's a really good lecture but that was our last session with him for the rest of my career as a nurse, well not ever because we'll see him around in the university which is quite nice, so then after Lee's session, Lee did all about public health, determinants to health, all of that, it was fantastic, after that we had our two other lecturers who are also fantastic and they're brilliant, they get us really involved, they do this acting scenario so they act things out for us and she's a fantastic actress, she's so good, she's missed her calling in life, she should have gone into acting but that was all about health promotion so as nurses we should be doing health promotion every single day, all day every day as a nurse and it's part of the NMC code that we should be involved in health promotion in our career and our profession, something that really good come from this session, so we were given a scenario, so the lecturer was a patient, the first scenario was based around sexual health, it was a patient that's just had a chlamydia diagnosis, a male patient, he goes off and he sleeps with a lot of women and he doesn't know who he's got it from so someone had to sort of volunteer to talk him through and give him health promotion surrounding this topic so I sat there and I was like this is my topic, I love sexual health, I can do this and I thought no no I can't do this, me and public speaking do not get on, I get very anxious and it genuinely I have fears and I start shaking, I have heart palpitations, I go bright red, I start sweating, I really have a tough time with public speaking, even just putting my hand up and speaking out in class, I just it really it gets to me so it's something I've always built on and I always push myself with, I always think do you know what I need to do this so I'm very aware of it, something I'm overcoming, something aim and goal by the time I qualify is to successfully stand up without any of those anxieties and issues, okay nerves is fine, good nerves is fine but the amount of anxiety needs to be gone and I need to stand up comfortably speak as a good public speaker by the end of my nurse and that's one of my goals so today put my hand up, I was the first person to volunteer and I was and then I sort of doubted it so I put my hand down really quickly and then the lecturer sort of caught me I was like oh yeah come on then so you can speak blah blah blah and I was like oh oh I've done it now I'm gonna have to go through with it so I was there like come on then and then just went through the whole health promotion spiel but I did it despite shaking afterwards I didn't realise I was shaking but I was there like afterwards like whatever I just did this was horrendous I went bright red I was sweating I could feel my heartbeat it was scary but I did it I got through it nothing bad happened to me from it and I think I did okay I could have done better but I did okay and I actually did it so that's a really good start so I'm really proud of that I'm proud that I've achieved something today that's been really good and let's just hope it continues tomorrow we're back on the research we're back on our poster topic I'm not too sure what we're going to speak about tomorrow I'm going to guess they're going to move on to the assignment part of the research because we haven't done that part of it so I think it's going to be the assignment part so hopefully that'll be a good lesson tomorrow I'm only in nine till one I think tomorrow so it's a short day so I've got a long weekend I've got Saturday to Monday off so that's it that's it for now I'll be back tomorrow I'll tell you all about my day tomorrow and just one last thing to end on if you've watched my previous vlogs I spoke about gardening so I've started gardening and I tend to kill plants and lately they've all been growing they've all been growing they've all been blooming something else that's happened is I've revived a plant from death how does that even happen so I had this aloe vera plant I don't know if it got over watered or whatever whatever I did to it I killed it it was green when I got it it was brown within days but it suddenly it started going green I've managed to revived it I've left it to itself I haven't watered it I haven't touched it I've put it on the window ledge in the sunshine and it's revived it's going green again look I hope you can see that but look here's where the um the little brown bits were you can see at the ends they're brown still but look how green it's going these were all dark brown plants like to come back from the dead also I've got a sunflower outside I put a sunflower seed in a pot just for the lolls I'll show you because you're gonna have to see this now that I've started speaking about it and it's growing it's growing look at him I hope you can see that here he is I've put him in with this plant because I thought he can grow up it and then he'll be tall he'll be a tall plant like the tree so he's just miraculously miraculously I need something to speak so he's just miraculously grown it's fantastic so now I'm gonna go and have some dinner I'm gonna eat chill out watch some Nashville anyone that washes Nashville I'm on season five why why Nashville why have you done this to me why have you created me into a an emotional wreck why have you done this anyone I'm not gonna spoil it for people that doesn't watch Nashville that's going to wash Nashville but a character is dead I'm not happy about this it's emotional it's terrible I'm traumatized but I'm hoping I've got a whole season left to go and then I'm done hoping it's gonna get nicer wishing praying for some positivity to end the season with so that's it that's from now that's it from me for now I shall see you all tomorrow can anyone guess what this is amazing and the weather has just turned beautiful after a couple of days of storms the weather's absolutely beautiful so I'm sat in my garden I'm just going through some books that I found at uni from a breastfeeding leaflet so today I've had a great day the lectures that we had today were all about dementia so it was all relating back to our assignment that we've got to write around Jeremy and he's got dementia and I think it's coming from a health promotion point of view so we've got to think of Jeremy holistically as well not just focusing on his dementia as such but the issues around that I think they haven't really said much about the assignment yet but we've had our dementia case study today and it's just lovely it was really nice really informative session and I've learned I've actually learned quite a bit even though I've worked in care homes for the elderly and that involved dementia patients I've actually learned quite a bit about dementia and more to the reasons why certain behaviors might be displayed with dementia patients and how to manage that and how to work that out so that's really interesting it's given me a really good insight and something that I can use next time when I'm out on placement so that's fabulous but for now I'm going to go and read my books that I have got from the library I'm so glad I found some books there's a couple of journals there's three journals and there's two evidence-based practice books that I found on breastfeeding so I've done well today so I'm back on it and back on the rationale I'm going to finish the rationale definitely by this weekend 100% I've only got 500 words left 500 or 400 words left and then I'm done and that's one module complete out the way I'm so excited but yeah that's my little spot my little sun spot next to Vera and I'll see you all next week 14 words I've done my rationale I've got it I've had a break bro


Hey everybody, welcome back to another magic review for hocus-pocus.com. My name's David and this is Got Change from Jason Yu and Sans Minds Magic. All right, so what is Got Change? Got Change at its core is a bill to coin transposition. You can actually do this with one coin and they say you can do it all the way up to four coins. So basically what you do is you come out with the dollar bill and you can hand it to your spectator, they can simply fold the dollar bill up into quarters, get it, quarters, and then they hand it back to you and then just dropping that dollar bill down to the table, it literally transforms in midair from a single paper dollar bill into four shiny coins. When you see it, it looks exactly like a camera trick. When you see it, you're thinking that's camera trick, that's editing, that's witchcraft, but it's not and you can do this yourself. All right, let's say you order this, you order it yourself, you get it, it comes in the mail, what are you gonna get?  Sans Minds always gives you actual physical DVDs, which is awesome, which is nice. The DVDs about 40 minutes long and then you're gonna get the materials that you need to create this effect. Yes, you will have to build this effect like other Sans Minds effects. This is a build your own DIY. Is it what I thought? You know what, I really didn't know what to think with this. I really didn't know what to think because like I said, watching it, it really looks like a camera trick. So a lot of your ideas about how this might be done almost get thrown out the window and you're like, I don't know because it just looks way too clean. So when I saw how it was done, of course it does use familiar methods that you and I have seen before in other tricks, but they're just packaged together really beautifully for this little miracle. All right, so if you get a chance to watch the trailer, they do talk about just the angle sensitivity and just kind of knackiness of this effect. And I would repeat that. This does have angle sensitive corners and issues. And I would say it's probably best with a 180 degree viewing area. Herman from Sans Minds does do the teaching on this and he does talk about how you could do it surrounded and he does talk about how you could do it in a performance venue that has more lighting or more lighting that you would like. However, they recommend that it has a 180 degree viewing area that you perform this in shadow or you perform this in dimmer light, the dimmer light the better. And it just pretend that this is a trick that involves IT. It doesn't involve IT, but pretend it does and use the same lighting that you would use for a trick that involved IT. And then as far as inspectability goes after the trick is over with, I'm sure people, their hands will dart out towards the coins. They'll wanna grab the money and then that's fine. But you will need to hide your wallet or put your wallet away because that will not be inspected. And if you couldn't tell from watching the trailer, that is his wallet that the coins, the dollar bills, they're bouncing off of it.  And that of course does not come with the trick. You don't get a Sans Minds wallet with this effect. Like I said earlier, the DVD is 40 minutes long and it's well shot, well miced, everything looks good. Sans Minds always makes really good DVDs. Like I said, Herman teaches the effect. Please watch it all the way through to the end before you even start working on this. This is a labor intensive effect. And so before you even start, you should know all the mechanics for how the trick works and you should know every single piece of time that needs to go into this. So I would recommend watching the entire 40 minutes from beginning to end before you even get out, scissors or glue or paste or anything, okay? Before you start any work, watch this all the way to the end. It's gonna be as well made as you make it, okay? And so if you're like me, you don't get excited about DIY projects, it's gonna be as well made as you make it. So if you wanna make this as best as you can, I would recommend you watch it all the way through. Then after you have it built, of course, you're gonna wanna practice. Herman recommends that you practice with one coin first until you get to be really good with just one coin and kind of move your way on up to four coins. He says in the video that four coins is ambitious, okay? It's an ambitious move, it's ballsy, it's like I said earlier, it's a knacky trick. So practice with one until you get to be super, super good and work your way up. Like go from a dollar to a silver dollar, okay? That might be a good idea. If you're thinking about walking around with it on your person, you know, table hopping or doing street magic and then asking, well, you know, what's involved as far as on my person? Like what do I carry with me? Like how much of my body space is it gonna take up? Obviously in the video, you see that there's a wallet involved, dollar bill involved and coins involved. All of those things have to be loaded around your person for this effect and you will need to get them all into a get ready before you start. So like any trick, you know, I think there's positives and negatives to this. I think positives are, I think once again, Sam's Minds has built a very bold and very daring trick that when you perform it, it looks just like a camera trick. Negatives, again, I say this is not for the faint of heart. This is intermediate to advanced level magic. A seasoned performer who has experience with audience control, who has experience working in the right venue, who has experience building gimmicks. Plus, I think you need to build in your own routine. You don't just walk up to a group of people and say, hey, watch this and you drop a dollar and it turns into four quarters. Then it's just like, what? You need a routine. Okay, you need a trick. You're gonna need pattern. You're gonna need to frame this in a story. Okay, and I don't know that Sam's Minds really gives you that. They give you the effect. So you're gonna have to add presentation to this, definitely. Right now it retails for about $35, okay? $35, like I said, 40 minutes of instruction and you get the materials to build your own effect.   You're gonna have to provide all of that yourself. So just throwing that out there, expense as far as what you're getting. Read as many reviews as you can. Ask some people's advice before you make your purchase to make sure this is the trick for you. As far as which kind of magicians I think would gravitate towards this the most, I think table magic and restaurant magic works great for this because of the fact that you need dim lighting and because the table is nice to catch the quarters. So definitely table hopping, restaurant magic, I think this works the best. All right, so that's everything I can say about Got Change from Jason Yu and Sam's Minds Magic. Of course, I wanna thank Hocus-Datch-Pocus for allowing me to have this trick so that I could do the review for you. And if you would like to purchase it for yourself, please check out Hocus-Datch-Pocus.com. Thanks, bye.


Hey everyone, Drew with GeoArm and I am back to talk to you about the Honeywell Home Pro Series, either the Pro A7 or the Pro A7 Plus. This is how you're going to get it wired for power. Now before you get started, make sure that you have a strip of between 18 and 22 gauge 2 conductor wire, like I have here, and you will also need a Phillips head screwdriver, like this. Alright, so the first thing that we're going to want to do here is you want to go ahead and make sure that your system is out of the box and ready to rock here. What we're going to be doing is we are going to be removing the back plate. As you can see, there's a screw on the underside of this device. Just going to back that out using the Phillips head, alright, like so, alright. Get that out of the way, put it off to the side here. Now we're just going to pop it off the back plate, like so, alright. Now you'll see inside of here that there's a lot of space for things. This cellular communicator will go inside of here, that'll be in another video. But we're going to be handling the wiring right now. Actually, the cell communicator goes in here, I'm sorry, the battery goes in here. So what we'll do first is we'll go ahead and we'll get the battery in place. So all you would do to do that is you just slide this piece off, like so, okay. We're going to take our battery. Our battery is going to go in this slot here, just like so, slide it in, okay. Then in order to get it plugged in, all you do is just snap it in place right here, just like so. Now this battery is plugged in. Now we'll go ahead and we'll get it wired for power, okay. Now for power. So what you're going to be doing is you're going to be taking your two leads, the black and the red lead. Red I usually use for positive power, black I usually use for negative. As you can see, our power supply is a DC power supply, meaning it does have polarity. So this side is the positive side. So DC positive is over here, DC negative is over here. So we're going to go ahead and get the red wire wired to DC positive here, like so. These things loose here. Slide that red wire underneath there, like so, okay, now it's got its connection.  Take the copper that's exposed, get that tightened down in place here. Okay, now that power supply is wired. It's ready. What you're probably going to want to do is you're probably going to want to feed this in through the back here like this, so that way it doesn't get stuck or however you want to feed it in, maybe through a side or however you want to do it. I'm just going to feed it in through the back just for the sake of the speed of the video. Now if you look closely at this device, you can see that it is labeled. There is a V positive and a V negative. So the V positive is going to be this terminal over here and V negative is going to be this terminal over here. So we'll go ahead and we'll get these tightened in and put in place. So we'll go red wire to V positive, which is here, get it tightened down using our Phillips head screwdriver. You've got that wire in place. Now the black wire is going to go to V negative. Go ahead and get that tightened down in place, okay. Now this device is ready for its connection. So we can go ahead and get this put back. So you want to make sure that you go ahead and slide the top end in first because it's got two little clips as you can see here, two little spots that this slides in with these clips here. So we just get that slid in there first and then we just push it down, okay. Now it's closed. Now we need to just get the screw put in back in place here. Once you get that tightened back down, this thing, we can go ahead and plug it back in. So we're ready to go here, okay. Let's see if our power comes up. That ladies and gentlemen is how you power your new Honeywell Home Pro Series Pro A7 or Pro A7 plus security system. You guys have any questions or any comments, please leave them below. Take care.

What is true love? How do we harness that love to reach Allah? Why I am here in this land, in this country, in this city? What brought me here? What does it mean really to have the Muwaddat of Al-Qandil? What can we do as a Muslim society to combat Islamophobia? What are those symbols of Hussain that are needed to be taken to Nidia and not to be kept in Imam Bahra and in the hospital? Alayhi salam. What can we do essentially to prepare ourselves?


The study aimed to explore factors determining the intention of healthcare personnel, HCP, from Greece and Cyprus to get vaccinated against COVID-19, finding that physicians, nursing staff, paramedical staff, working in Greece, age, mandatory influenza vaccination for HCP and overall management of COVID-19 pandemic were significant predictors. This article was authored by Vassilius Raftopoulos, Stelios Iordina, Angeliki Katsipi, and others.


I thought that we've been getting stops the whole time, but I think they had something like 15 offensive rebounds first half I thought that we got that we scared the rebound then we started playing with the pace and the poise We're supposed to play with the first half putting love and picking roles getting downhill And then it's obviously a make or miss league and we started hitting three's I think confidence grew and I think that the game slowed down and we started, you know picking picking the matches We wanted how about the drives and kicks in the ball movement overall and obviously finding you in the corner Knocking down those shots. Well, that's what happens, you know turn the ball over 20 some times You know you get extra possessions to get what else involved I thought that Jared Allen made some credible passes out there out the double team that we've we've been harping on when they pull Over I think the game with the Angelo and Kieris just kind of slows down for them where sometimes it takes them struggle to ball shooting I thought Kieris struggles first half told them to stay aggressive But also the look for others when you you know when you when you are you when you are down a little bit But overall those you know to hold this team 86 points this team might not be a good defensive team But they're pretty good offensive team. So it shows you how well we play tonight and How much how much pride do you take in just giving love the battle that you did try to try to limit on try to Fun him. I mean, we know he's our number one option For him only get eight or nine a tenth and if you look at it I mean most of them the game without a hand when that and so that's my thing when you go against Blake and those guys to You know, I've been on other teams where they wouldn't they wouldn't let me front So I have to say behind and now they get 20 attempts at the glass and maybe you know They double me because this league now It's you know, stay home and choose and let you know No, no stay home for no issues threes and let them just take the twos But they're letting me front and not let them catch the ball and makes it a lot easier for me And anytime you've got like Jared Allen behind you to believe pressure I think you only messed up one time on the law pass But if you can help me nine times out of ten, I'll be fine


The term highly sensitive has a deeper definition than what it's become known as in today's society. It was coined in the mid 1990s by psychologists, Elaine and Arthur Aaron, to describe individuals who process events or situations more than others. Unfortunately, the term came with a negative stigma. For many years, society perceived highly sensitive people as over thinkers, or people who took things too personally. They were perceived as sensitive, touchy, high maintenance. Many were diagnosed as autistic when they may not have actually been on the autism spectrum. Although individuals with autism and high sensitivity experience sensitivity to their environments, they aren't interchangeable. Here are a few traits many HSP people exhibit or experience. Notice changes easily. Not everyone's central nervous systems are the same. Highly sensitive people tend to have a greater capacity for feeling and processing more information in their environment. Consequently, HSP's react with more stress and quickly notice subtle changes in their environment. According to Andre Solow from Psychology Today, both though being autistic and having high sensitivity are two different things. Autistic children and HSP's may react in a similar way when they get overwhelmed by a noisy or busy environment. Those with autism shutting down or having tantrums in the HSP child may act the same way if they haven't been taught strategies by their parents, like having time alone and learning to say no to avoid becoming too overwhelmed. Sound sensitivity. Did you ever wonder how on earth Superman kept his sanity? The guy had super hearing and if you are an HSP, you might share his pain. As a result, a highly sensitive person is more reactive to sounds in their environment, so loud noises can be uncomfortable or unbearable. According to researcher Bianca Acevedo and her colleagues, being an HSP is a trait, not a disorder, that 20% of people and many other species have. Studies have shown that highly sensitive people are also affected by other people's moods. This sensitivity is also common for autistic people, but they have a different brain structure compared to highly sensitive people. The overlaps in those with autism or HSP occur with sounds and noises. But even though both conditions involve a sensitivity toward sound, the reasons are different. An autistic person's brain structure may be the cause of the noise sensitivity. Researchers White House and Bishop say it may be due to processes in the brain interfering with encoding and early processing of sound. Either way, being super sensitive to sound means that normally noisy environments, like being in a small or busy downtown center, may make you feel uncomfortable or overwhelmed. There was a theory that processing sounds was at the heart of speech and language learning problems and sound sensitivity in some autistic people. But in the early 2000s, Nicole Russo and her team at the Auditory Neuroscience Laboratory disproved this theory and established measurable differences in auditory pathways, which can explain why speech or complex sound causes sensitivity. For HSPs, their brains activate in areas associated with empathy, social processing and reflection. According to Rachel Samson, psychologist, HSP is a marker of an expansive central nervous system. So it's not simply down to genes. Your environment also plays a role and can help determine how it's handled as an adult. Samson writes that studies suggest that an unsupportive and stressful childhood environment may contribute to the development of high sensitivity. They may feel intense emotions or pain more than other children and may not learn how to constructively deal with their issues and end up in a negative cycle of being ostracized or more hurt. On the plus side, if they can learn how to handle their sensitivities, like when to graciously decline an invitation or how to exit a situation when it becomes too much, that can be supportive. Our genes and environment contribute to our mental and health development, but they don't define us.


Welcome to ITU Telecom 2017 here in Busan in the Republic of Korea. I'm very pleased to be joined in the studio today with Satoshi Amagai, who is President and CEO of the Moffiria Corporation. Mr. Amagai, thank you very much indeed for being with us today. Good morning. I'm very honored. Good morning. I wanted to ask you about the buzzword here at Telecom is smart digital transformation. What does smart digital transformation mean to you? Of course, getting smarter is good and beneficial to many people. But the other side of the same coin, getting smarter may have some potential risks because getting smarter means some very important, precious processes done invisibly or remotely so that you cannot confirm the process by yourself. At that point, I would say our biometrics technology should work to confirm that people, especially the people, who are correctly the right persons. The technology that you're developing, it recognizes your veins, is that right? And basically then identifies you to financial institution or to be able to travel or that kind of thing? Yeah, yeah. Luckily in Japan, we have a good example. I don't know if you know that, but in Japan, in major banks, I would say over 80%, 80% of ATMs incorporate vein authentication technology.  And again, in case of Japan, until recently, only vein authentication technology on ATMs, not the facial recognition or no fingerprints. That may mean that the vein authentication technology is competitive and safe. And in case of Japan, can I... Yes, please, absolutely, yes. This is the first moving prototype where our vein authentication technology is included. So this is, okay, maybe about eight years ago, this kind of mobile phones are very popular. But on the backside, all the key components are in here. So all you have to do is just grab this way, then it identifies you or you, almost by 100% accuracy, nobody else. So you don't need any pin codes or passwords. So just grab this way, then almost 100% guarantee of you are the user. That's fantastic. Yes, that's great, unless somebody is taking your hand and holding it that way. But no, that's amazing. That's great. And are you going to be obviously looking to put that technology into more modern phones as well? Exactly. Of course, in financial areas, not just the ATMs, but the regular process at the bank stores or offices, or even the current trend of mobile banking, guaranteeing that you are you is very important. So no other people, no hacking, no forgery, no copying, no faking, that should help. Because apparently it's quite easy to replicate, well not easy, but it can be replicated, a fingerprint can be replicated. Exactly. So that technology is in full proof by any stretch of the imagination. I wanted to ask you, in terms of technical standards, what technical standards are needed to build a safer and secure digital financial service? I would expect the ITU, the global standard organization like ITU or ISO, will help us a lot to be well spread into the worldwide. And maybe with standard or basic standard and some of the flexibility to fit the local areas' situations. And what about the barriers and challenges in terms of financial cryptography and data security? How do you think we can overcome them? Obviously this is one of them. Right, like I said, maybe standardization is easier said than done, because unfortunately even now our main technology algorithm or system is not compatible with another company B or company C. So that from the users, the customer's point of view, you have to worry about what to select. Once you select a company B's technology, that's not compatible with ours. So that's why, as I said, maybe the global standardized non-profit third party organization like ITU should play a role as a coordinator to what the best solution for users or customers. So we can certainly try, obviously, and I'm sure there's a technology such as this is of course to the benefit of everybody. So it would benefit everybody, of course, to have standards that mean that this could be put into any telephone or any ATM, absolutely mobile products, exactly such as the one I'm holding right now. And we've talked about essentially what makes this different to everything else. Is it unique, is it a unique technology, this finger vein technology? I should say so. Compared with most known fingerprints, this technology is much, much younger. To the best of my knowledge, fingerprints has more than 100-year experiences for usage over 120 or something. But in case of ours, our original technology was born in sunny just only 20 years ago and other competitors are somewhat in the same case. So very young, but being the youngest means more advanced technology, I would say. So that's how we would like to complement the area where the current biometrics alternatives don't cover 100%. And we think we have our own room to fit into. Right. And in terms of testing, obviously it's a young technology. I mean, obviously the initial fingerprints were ink and onto paper there. But have you tested it in very cold environments? Do veins react differently in different temperatures, et cetera? Yes, thank you for the question. To be short, vein authentication technology has two big differentiating advantages. One is vein structure or blood vessels cannot be seen from outside in normal cases. That's why very hard to make a copy. Face, you can do it. Fingerprint, you can do it. Even nervous, you can make a copy from outside by shooting. So that's how making a copy or fake ones is most difficult. And also, because the vein is located inside the body, very little influences from the outside conditions compared with the fingerprints.  You said it. Once you are dead, no more blood current. So vein authentication can be possible. But in other words, as long as you are alive, even though you are faint or unconscious, but this can tell you are you. That's great. And finally, I just, obviously you're here attending ITU Telecom World 2017. We're here in Busan in the Republic of Korea. You haven't traveled too far from, obviously, Japan being relatively close by, but however it is, I'm sure an investment in time and everything else. I just wanted to find out from you, what's the value of attending events such as this? And have you got a key message to participants here? This is a very good opportunity, a first time for me and maybe a couple of things. One is good to know the global situation, what kind of concerns or worries they have in where. And the second thing is, it's a good surprise that not a few people refer biometrics in their smart ABC presentations or comment making. So that's good to know. But again, almost very few people know about vein authentication. So it's a good chance for me to introduce what vein authentication technology is and how our technology helps other people concerned. Well, that's wonderful. Thank you very much for sharing this with us. It's been fascinating. And we look forward to catching up with you again, perhaps sometime in the future. Thank you, my pleasure. Thank you.


Archaeologists in Japan have just uncovered a lost piece of history that they are hailing as the greatest discovery of the century in Japan. The discovery of the ruins of a castle built by a feared Japanese warrior leader, can you say warlord? Anyway, this discovery has sparked widespread jubilation because this guy is regarded as one of the most powerful individuals to ever influence the Japanese people ever and widely regarded as the second great unifier of the Japanese people. A samurai by family lineage who began a state of empire by controlling parts of Korea with only the combined might of China and Korea to keep the explosion of Japanese interest at bay. The second great unifier of Japan never reached the sworn title of Shogun. Shogun is the title of the military ruler of Japan as appointed by the emperor and therefore the de facto ruler, as it were, instead. He would adopt a series of high ranking roles and in doing so he probably bettered his interests with both the people and the elite and, this is reflected when for example, he hosted the emperor in his palace in the year 1587 as the imperial regent to the empire. This was a direct adversary role and the ability to influence is very apparent within this position at various levels of order from the highest level, through military ranks and even banishing the Christian missions in 1587. References do exist to prove the existence of a great castle structure, most notably from court nobles, but until now it seems no solid physical proof of its existence has ever been recovered. On May 12, the Kyoto City Archaeological Research Institute announced the discovery of remnants of a castle wall and moat within the grounds of what now constitutes the Kyoto Imperial Palace. The castle is believed to have been completed a year before Hideyoshi's death and diaries of court nobles of the time only refer to the structure as Hideyoshi's palace without giving it a formal name. The site is located in the southeastern section of the Kyoto Imperial Palace and covers about 32 hectares. Hideyoshi resided at the palace when his son and successor received his court rank. Remnants of the walls and moat were found under the foundation of the Kyoto Shinto Imperial Palace which is where emperors resided after abdication. One section of the castle wall, constructed in a north-south direction, measures about eight meters in length and the wall measures 1.6 meters high in places and was comprised of three to four stone layers. Although the upper portion had collapsed, the wall in its prime was likely around three meters high. The techniques used to construct the castle wall likely date to 1568 based on the careful manner in which blocks of stone were placed and researchers have theorized that the moat was originally at least three meters wide and three meters deep. References that had fallen from the castle wall as well as gold-plated roof tiles that bore the family crest of the family were also discovered in the filled-in moat. A professor specializing in the history of castle building at the University of Shiga Prefecture said, historical references to a place had led most experts to believe the structure was only a residence surrounded by a wall. Note that the discovery of remnants of a castle wall as well as gold-plated roof tiles indicated a magnificent building stood here and that this is the greatest discovery this century related to an excavation of a Japanese castle. Hideo-shi died here in 1598 and in the 1600s the castle walls, gates and other parts were destroyed before the construction of Kyoto Shinto Imperial Palace in 1627, which completely covered the remnants of the castle only to be rediscovered in 2020, much to the delight of researchers in Japan who have rightly hailed this a great discovery that confirms a past narrative. But what do you guys think about this anyway? Comments below and as always, thank you for watching. Hey guys, this is Buzz Weaver, the voice of the Lost History Channel.

Hello and welcome to the session. In this session we discuss the following question which says the name of two samples of sizes 50 and 40 were respectively 63 and 54. The corresponding standard deviations were respectively 9 and 6, obtained the standard deviation of the combined sample. Before we move on to the solution, let's discuss the formula for the combined name and combined standard deviation. First we have the combined name given by x bar is equal to m1 x1 bar plus m2 x2 bar and this will be upon m1 plus m2. Then next formula is for the combined standard deviation given by sigma or sigma12 that is we have sigma is equal to square root of into sigma1 square plus d1 square this whole plus m2 into sigma2 square plus d2 square and this whole upon m1 plus m2. Now here we have considered two series like this be series1 is the as the series sigma1 is the under deviation as the series1 is equal to x1 bar minus x bar and we know that this x bar is the combined name for the series2 we have m2 of the series the static name of the series sigma2 is the under deviation of the series d2 is equal to x2 bar minus x bar this is the key idea that we would use for the solution of this question. Now consider the question in this we have given two samples their respective sizes their means and their corresponding standard deviations and we are supposed to find the standard deviation of the combined sample. So let's see the solution now. So here we have m1 which is the size of the first series which is given as 2 is the size of the second series which is 40. So we have m1 equal to 52 equal to when next x1 bar which is the arithmetic mean of the first series and it is given as 63 and the arithmetic mean of the second series is 54. So we have x1 bar equal to 63 and x2 bar equal to 54. So let us find out the combined mean which is denoted by x bar and this is equal to m1 x1 bar that is 50 into 63 plus m2 x2 bar which is 40 into 54 and this will upon m1 plus m2 that is 50 plus this is equal to 3150 plus 6 0 and this will upon 90 further this is equal to 5310 upon 90 this 0 cancels with 0 and 9. 50 9 times is 531 so we have x bar which is the combined mean is 50 without b1 which is equal to x1 bar minus x bar and so this is equal to now x1 bar is 63 so 63 minus 59 which is equal to that is d1 is equal to 4. Now next d2 is equal to x2 bar minus x bar now x2 bar is 59 which is equal to minus 5 that is d2 is equal to minus 5. Then we have the deviation given by sigma or sigma12 is equal to square root of m into sigma1 square plus d1 square the whole plus m2 into sigma2 square plus d2 square the whole and this will upon m1 plus m2. So now the combined standard deviation sigma12 is equal to square root of now we can substitute the values for n1 n2 sigma1 sigma2 and d1 d2 so here we have the standard deviation of first series which is 9 minus 9 sigma1 square would be 81 plus d1 square d1 is 4 4 square is 16 whole plus n2 which is 14 into 2 which is the standard deviation of the second series which is 6 so here 6 square would be 36 plus d2 square and d2 is minus 5 minus 5 square is 25 and this whole upon n1 plus n2 which is 50 plus 40. So here we have used sigma1 as 9 and sigma2 as so further this is equal to that is sigma12 is equal to square root of 50 into 97 plus 40 into 90 and this is further equal to 50 plus 40 this upon 90 this gives us sigma12 is equal to square root of 7290 upon 90 81 times is 729 so we have sigma12 is equal to square root of 81 which is equal to 9 therefore sigma12 is equal to 9 that is the combined standard deviation denoted by sigma12 or you can say sigma also is equal to 9 so this is our answer this completes the session hope you have understood the solution of this question.
