Hi, my name is Shu, and this is a work with Rafael Del Pino. So what we do is that we propose a more efficient lattice space around optimal blind signature in this work. And our work can be extended to satisfy partially blindness, and it's also the first scheme to be proven securing the quantum random oracle model. We follow a generic blind signature recipe by Fishlin05, where the user commits to a message and creates its comm. And the signer will sign on this commitment. And user, when given this signature, will provide a zero-knowledge proof that this signature is a valid signature on this commitment, which is a valid commitment on the original message here. And the whole issue here is that this signature and this commitment must be kept hidden for blindness to home. And our work is basically providing a new approach to this component. So prior to our work, there were three main lines of work for blind signatures. One is a short type blind signature. And this has been the most active area of research, but HONK et al. recently showed that provable secure parameters require a signature of several megabytes. There's also a very recent work by Lubaszewski et al. that constructs a new type of blind signature from one-time signature with an OR proof. This is an interesting deviation from prior techniques, but it requires an upper band on the number of signatures at setup. Finally, the third one is instantiating fish in the generic construction. And agrar al. et al. creates, well, provides two generic constructions. And the first one is based on random oracles and evaluating that random oracle using FHE. So this is rather heuristic. However, the second one is very efficient, but it requires a one more SIS assumption, which is non-standard and needs a bit more cryptanalysis to have to base confidence on. So our work in more detail is that we provide the first round optimal and a scheme that supports unbounded signature. So the verification keys can support any unbounded polynomially mini-signature. It's also based on standard lattice-based assumptions. And it's the first to be secure in the quantum random oracle model. And it is more efficient than prior works, so it provides around 100 kilobyte for the signature. And since it's a generic construction, we could be able to plug in recent NIZKs to further lower the signature size. And agrar al. et al. recently updated their paper. And what they did was that they used the recent NIZK by Lewoszewski et al. in crypto this year to achieve a shorter signature size than what we did. So at the heart of our construction, we provide a new commit, then sign, and zero-knowledge proof protocol. So here the client will create a commitment to this message. It will send it to the signer. The signer will sign this and then provide a signature back. And what the client wants to do now is that it wants to prove in zero-knowledge that it has a commitment and signature pair such that this commitment opens to this public message and that this commitment is also signed by this signer. And here we want to keep the commitment and signature private because this is how we get blindness for the resulting blind signature. And we know how to do this efficiently in the classical setting using discrete log or DDH type of arguments. But it's surprisingly non-privile to do this in the lattice setting.  So at the core of our idea is that we use an ABB style signature for this signature and to proceed with this commit and prove protocol. So for ABB signatures, the message is embedded into this lattice and the short vector E will be the signature. And this is a transformation inspired by Del Pino et al. But here we'll just replace this message times G by a commitment C. And this commitment will be using a very traditional lattice-based commitment and it will be in the form of BR plus message times G. And here, if we combine these equations together, the client can recompute this equation and transform it into this kind of public matrix time private short vector equation. And at this point, this is a simple SIS relation with an accompanying efficient NIZ team. So for more details, please refer to our full presentation or our paper. And although I didn't explain it in detail, the most technical part of the work was not at the core idea, but it's a more subtle part where this commitment C has to be proven well-formed via NIZK. But here, due to security-proof issues, we need this to be multi-proof online extractable, which is a very strong property. And to achieve this in a relatively efficient manner, we rely on the recent techniques to get this strong NIZ game. And this will give us also as a bonus, security in the Q-ROM. Thank you for listening.

Hello, everyone. I'm Sarah, a cloud orchestration software engineer in Intel. The container runtime and language runtime are my focus now. I have made some performance optimization contributions to the PHP language open source community. And my teammate is Yong Li He, a senior cloud software engineer at Intel with 15 years. And many effects on the network security and Linux system. This cloud journey began with OpenStack in 2011, where he eventually became a commuter on mobile. In 2021, he embarked on cloud native and Kubernetes, enhancing Istio service mesh security. Today, it's my honor to be here to show our topic, a Washington runtime for fast protected by T. We will show you the background of confidential computing and T environment. And the current solution and why we choose a Washington runtime for fast protected by T. So we have four parts. Firstly, what is traditional confidential computing and now data security is a critical issue. Confidential computing focused on securing the data in use, which is a strong demand in many cloud computation cases. The data being processed and the techniques that are used to process it are accessible only to authorized programming code. These are invisible and unknowable to anyone else, including the cloud provider. Confidential computing is important in many commercial scenarios. For example, financial firm space and endless problem of digital safe and fraud. Recently, confidential computing can be employed in an AI based money laundering detection approach. Utilizing federated learning. In this strategy, team often work in different companies, collaboratively to build a shared prediction model. Unlike standard machine learning approaches that require data centralization. Federated learning allows for training data to be kept in the local environment, such as banks internal system with no need to store data in the cloud. They can use confidential computing to make sure that the right programs are operating on the right data rather than being shared across all companies. Besides, there are all sorts of scenarios in the financial services where confidential computing could help. As many companies rely more and more on public and hybrid cloud services, data privacy in the cloud is so comparative. Confidential computing provides more data security assurance and encourage companies to move more of their sensitive data and computing workloads into the public cloud. Specifically, a hardware based trusted execution environment in CPU is built for confidential computing. How TEE secured it in use? The embedded encryption case machine is ensured that the keys are accessible to the authorized application code only. If the authorized code is hacked, the TEE denies access and can solve the computation. In this way, sensitive data is protected in the memory. Now, three hardware platforms already support the TEE. Internet SGX, ARM Trustroom and AMD SCV. They have different implementations. For example, Intel has been a pioneer in confidential computing by introducing software guard extensions that are known as Internet SGX. It continues this string with upcoming trust domain extensions, TDX. AMD also introduced secure encrypted virtualization to isolate GAS and the hypervisor. ARM Trustroom isolates the critical security, firmware, assets, and private information for the rest of the application. As we can see that different TEE environments have different programming models based on their own hardware platform, which brings overhead for programmers. For example, software developers need to create in-play and debug applications enabled by Intel SGX. The trusted function is called and the code running inside in play consumes important data directly. And Intel SGX is introducing a new architecture to help deploy hardware isolate virtual machine. And AMD SCV is an extension to the AMD V architecture, which supports running encrypt virtual machine under control of KVM. Encrypted VM has their pages secured such that only the guest itself has access to the unencrypted version. Now ARM already gave a client solution in mobile. Applications in the conventional OS and TEE refer to untrusted and trusted world. A TEE-based kernel is used for scheduling memory management, crypto methods, and other basic OS functions. TEE Functional API here defines the interfaces for communicating with the trusted world from untrusted world applications. The trusted applications have access to the OS functions exposed by the TEE internal API. Furthermore, the hypervisor and virtualization makes it possible for many TEEs in a single device. There are two separate hypervisors in one device. For the secure world in the right, the monitor mode just manages the actual switch of state in the course from the normal world to the secure world. The boot code sets up the initial state of the secure world. However, all about with just a client solution, many developers are trying to bring TEE to cloud at computing and more scenarios. So how TEE exists in cloud native? Let's say the confidential container project. Confidential containers project which is to standardize confidential computing at the container level. This will enable the Kubernetes users to deploy confidential container workloads by using the familiar workflows and tools without extensive knowledge of underlying confidential computing technologies. Now, a zoomed-in Kubernetes service supports adding confidential computing VM nodes as agent roles in a cluster. These nodes just help you to run system workloads while keeping a special block of memory encrypted per container. The Kubernetes scheduler will dispatch these TEE containers in a cluster which is convenient to run for cloud native in a cloud native scene. So let's dive into the working model for TEE containers briefly. The TEE images needs twice building. Normal building is the same as the process of normal images. Then the TEE devil tool will rebuild it and encrypt some layers. Finally, we push these container images into the image registry. This registry is responsible for storing and delivering encrypted container images. The secret storage is responsible for storing secrets that the workload needs in order to run, such as disk decryption keys, and it delivers these keys to the TEE application. Finally, in summary, the confidential containers projects have several advantages. It keeps TEE's confidential data secure. It removes the SP from trusted computing base, and it constructs the general destination infrastructure, and it's compliant with outside runtime specification. And it could be deployed in any public cloud Kubernetes platform. And it really standardizes confidential computing at a container level. Then just let's take a look at a specific example of CoCo, confidential containers. Inclava provides industry with an open source container runtime architecture for confidential computing. It's led by the Anababa cloud operating system security team. Let's see the workflow of Inclava containers. The Kubernetes is initialized container runtime interface request to container D, such as request to create a pod. A CR container D project is provided for container D. After container D receives a request, it forwards that request to shame-rime. Shame-rime can create both run-c and run-e containers. Here, for example, create a run container, use libOS to convert a comma image to a Tee image. Run-e will create an enclave in the container and run the application in the enclave. Run-e just loads the inter-sgx driver into a container. Create a plus first in the container s, init-run-net, and then use init-run-net to create the enclave. The enclave is Tee protected by inter-sgx. Here, it includes libOS, language runtime, and applications. Now we can see that a trusted application is running. Well, this project really reduces the high threats of confidential computing and provides developers with real practice. However, the current confidential container technology still has some shortcomings. The use and development costs are relatively high due to the different hardware. Since the Tee encrypted container image for different platforms can be reused easily, which brings a big storage and network overhead simultaneously. Encryption induces a bigger image size, big footprint, and the isolation is still too coarse due to the whole workload estimation. So, we want to try some solutions. And the wasn't runtime, then let my teammates only introduce the wasn't runtime in the detail. Thank you. Hey, everyone, this is Yongli He. I'm very glad to present this to you. Thanks for watching. We're going to go through two sections. In section three, we talked about how wasm could be used in serverless platform by two users cases. In second section, we talked about how put wasm runtime into hardware Tee. In this section three, we're going to talk about what could be done by combine wasm and the hardware Tee. And to follow two user cases, the open source serverless platform, Canadian, and the wasm native platform, Formum Spin. WebAssembly is a binary instruction format for a stack-based virtual machine. Wasm is designed as a portable compilation target for many programming languages. Enable us, deployments our apps on the web. It's also enable us to deploy our wasm applications in server by using some specific wasm runtime. For server-side application, especially in the edge cloud, the safety and the trusted run environments is where we demand. We combined wasm with hardware trusted execute environments. Then provided a safety and the trusted cloud. This means we need to put wasm runtime into hardware trusted execute environments. We will soon to know we gained more than a safety solution. We will talk more about it soon. We have several different hardware trusted execute environments models. For example, the compact solution like Intel SGX requires specific SDK and tools to build your applications. But the TDX instead, in the VM level, provided more familiar tools for developers, required less effort and could transit the legacy application smoothly into trusted domain. WebAssembly running in the trusted execution environments have more benefit than we expected initially. For example, in the function as a service platform, more specifically in the Knetu, function boot time is a key factor for user. Wasm function have a unique benefit to provide help on the fast boot, even running in the trusted environments. Wasm runtime is small and identical to every wasm application. In traditional applications, each application has their unique and different runtime requirements. We already tried to improve the image boot up speed by letting it boot from a snapshot. That's very helpful. Now combined with WebAssembly makes Snapshot solution become more attractive. This means less disk space taken and quick boot. And a pre-booted function run time queen is then became possible. We choose two example platform to introduce more about combination of the wasm and trusted execute environment. Knetu is an open source function as a service platform. And this bin is a wasm-netu cloud. Knetu has two main components, the soaring and the eventing. These two components work together to automate and management the applications. Knetu takes care of the details of networking, auto scaling. That developing team can focus on more about the serving logic itself instead of the everything details in the platform. In the Knetu function is a key component. Knetu provides a simple programming model to not require in-depth knowledge of Kubernetes and the container. Knetu functions is easily created and easily deployed into Knetu platform. When you build or run a function, the container image is generated automatically for you. Each time you invoke your code, Knetu will boot several posts for you as required. Then run your function. That is your code. Combine the function as a service platform with trusted domain-based wasm application. Means we need to put the whole wasm runtime and the wasm binary into the trusted domain. This is going to get a safe and trusted function as a service platform. This will address some concerns from users. For example, a company may run a fast platform. They need to secure the interaction with their function and protect their critical data. Put their function and their data in trusted domain could prevent machine attack and prevent malfunction operators. A talented company may want to protect their function code and algorithm data. Want their data in the trusted domain. And won't leak their data to cloud service provider or other functions in same provider. To address this concern, we build the function as a wasm binary. And then incorporate the binary. Then use WebAssembly here is mandatory. Because the files usually build your function from your source code. But for security, we're going to incorporate our wasm binary. That totally breaks the function as a service cloud's workflow. We even could not provide a correct container image to run customers binary application. But with wasm, we could address this problem. Because WebAssembly's runtime is the same for all wasm binary. Now let's discuss another example. Build a trusted execute environment with wasm native cloud. For instance, spin is a wasm cloud. Every application in the cloud is wasm binary. Spin is kind of wasm runtime build on some wasm engine, of course. And spin also interface wasm binary to host in a standard way. This is a very simplified chart to elaborate how spin works. Spin is open source framework for building and running fast microservice with WebAssembly. It aims to be the easiest way to get started with WebAssembly microservice. And take advantage of the last developments in the WebAssembly component mode and the wasm time runtime. Spin offers the simple COI that helps you to create, distribute, and execute applications. Spin also offers a standard library to help your wasm applications interact with cloud and with the host side service. The wasm engine links your application with host components. That host components provide your wasm application services like HTTP, Redis, and other APIs to make wasm runtime secure and trusted in the wasm native cloud. We conclude that put all the spin in trusted domain is a smooth solution. For VM like TEE, for example, the Intel trusted domain extension, this is easy to do so. In section 4, we are going to talk about how we put the wasm runtime in trusted domain. We partition this topic in several small sections. Talk about three things. First one is how this works for trusted domain extension. Second one, we talk about how it could work for SGX in cloud. And the last part, we talk about what wasm runtime available to begin with. For VM level trusted domain, we have all to support wasm runtime. But need we treat that VM a little bit differently? For example, in Intel TDX, there is a TDX tools provided to help developer build their individual components, package, or install pre-build binary. Even create guest image. This is a very nice start point to build wasm runtime in the Intel TDX. As another example, the SGX in-clay needs different support. We evaluate the open source ego project. That's very helping. Developing confidential applications require the knowledge and the significant code changes normally. But with ego, you can skip that and write your code as you usually do. Like SGX does not exist at all. With ego, we don't need to refactor the wasm runtime. We could use three simple commands to build, send, and run your wasm runtime in the in-clay. As shown here, ego given the wasm runtime example, which is also mean we immediately go to a working start point. That's exciting things for starting exploring new projects like this one. We can put our energy to put it together with fast platform, instead worry about how to put the wasm into in-clay. We also have another good choice for awesome runtime, the WebAssembly Mikro runtime to work with. This is a lightweight standalone WebAssembly runtime with small footprint, high performance, and highly configurable features for applications. They then target for embedded edge cloud, support trusted execution environment, natively. Wammer is a good choice for edge cloud to further reduce footprint and size. Wammer is a safe base to implementation, but not a problem while help of ego. Wammer itself could be a simple library to be a part of Go version Wammer. Thanks everyone. That's all I present today. Thanks for watching.


Everybody forced here ripping a couple boxes of 2022 luminaries baseball hobby for Scott you here. We go Scott. Good luck Let's see one of those books one of three Jose Altuve Hit King's Auto My slow numbered Altuve there Got a ton of hits right. Well, let's see a really big one here. Come on.  Thank you again. We're gonna get put these cards out to you shortly


Think about this in the context of trickle-down economics Isaac Newton was born December 25th. I can't remember the year but a long time ago and What he has done his discoveries Have changed the world They have trickled down or more accurately flooded down to all the rest of us who are not geniuses who are not anywhere near as creative and as productive and As smart as Isaac Newton was but Isaac Newton has made all of our lives better They could not have been an industrial revolution without Isaac Newton They could not have been a technological revolution today without Isaac Newton Very few of the bridges that you see out They could have been built without Isaac Newton We certainly wouldn't have gone to the moon without Isaac Newton We wouldn't have any any any any of the material goods that we have today without having an Isaac Newton Talk about trickle-down Isaac Newton made all of our lives hundreds of years later Much much better off than they would have been Because of his discoveries because of what he did That is the essence of trickle-down. I don't like the term trickle-down. I Like the idea that we all stand on the shoulders of giants We all stand on the shoulders of atlases to refer you back to Atlas shrugged There are people out there who are incredibly productive There are people out there who are incredibly smart There are people out there who are incredibly knowledgeable and They make life better for us by odors of magnitude They make life better for the poor for the middle class for everybody Much better and without them They would be no jobs for the poor No jobs for the middle class without entrepreneurs without inventors without engineers Without the so-called rich without those people in the top. I don't know 1% 10% What do you think jobs are gonna come from Who's gonna who's gonna invent the next great thing? Oh? Bill Gates and and all these rich entrepreneurs out there. They've got all this money And we don't see any of it What about there's no trickle-down? Of course there's trickle-down. You've got an iPhone. You've got an iPad You've got all the ticker. Oh, you've got an internet Internet is a huge trickle-down to you to you who didn't invent the internet I didn't invent the internet a Bunch of entrepreneurs did most of the work to commercialize it to make it possible for me to use it They made a lot of money at it and who benefits from that me. I get to use the internet What did I pay for it zero nothing nada? Of course economics is about trickle-down Again not trickle-down flood down What a fall down it is the great entrepreneurs the great producers Who make our economy run? Not the workers. Sorry. I mean workers are important. There's nothing against work. Work is good work as moral workers virtuous But you don't change the world The people who change the world the people who make your work possible the people who create the jobs the people who have thoughts about how to Take money and invent something completely new and invest in something completely outrageous that nobody would have thought possible And thereby creating jobs in some Field that we can't even imagine today.  He is Going to change the world and impact everybody else Talk about call it trickle-down call it flood-down. He's gonna make the lives of everybody who didn't invent this cure for cancer Everybody's lives better and hopefully he becomes super rich as a consequence And then the left and some people on the right will say oh, he's got so much money That's not right. We're not benefiting from all the money. He has We need more trickle-down. You already got the trickle-down. You got the drugs.  We've got massive quantities of employment and on top of that He's taken all his money that he's made and he's investing it That's providing capital for other businessmen to create more jobs and more products and more benefits for your life and for my life I Mean every way you slice this every way you slice it It is the successful rich businessmen Who create the goods and the jobs?  He's created Amazon Changed all of our lives Changed the entire landscape Created hundreds of thousands of jobs Some of them at Amazon some of them at UPS and FedEx. Yeah, some jobs went away at retailers who are less efficient We are benefit because we get convenience and price And yet Jeff Bezos then he takes all that money and he invests it's one of his investment is in a space Exploration company. He wants to go to Mars the highest people people work for him one day We might go to Mars and who knows what that will open up in terms of Benefits to mankind other parts of his money. I'm sure invested in all kinds of other companies Basically their money is going to do what? To create jobs and to create goods and products that we consume It's not that businessmen exploit us It's not that businessmen do nothing We do all the hard work and they benefit from our hard work and they they take it away from us. No No, it's the opposite they do the really hard work and The really hard work is not physical labor turns out never has been The really hard work is the thinking necessary to invent Amazon the thinking necessary to discover the laws of physics the thinking necessary To improve the light bulb as Thomas Edison did or to create a whole electricity industry As Thomas Edison did never made it, you know That's the real work and that's the work that benefits Humanity that's the work that we all benefit from that's the work that trickles down But even in the more mundane view perspective the purely money materialistic sense It's not trickled down. It's a flood Think about Think about You know cutting taxes for the rich They have more money What are they gonna do with that money? What are they gonna do with that money? Now if you had money if I had money we're likely to go out and spend it indeed I just read a report. Where is it? Yeah, that yours consumer spending Rose in November, it's it's I think it's rising in December again. It's it's really really high and That our saving rate the amount of money we save is That a 10-year low now think about that How do what is the money to build new factories come from where does the money to build new warehouses the stores that are buying new trucks? Come from where does the money to invest in new technologies come from? It comes from our saving It comes from you can't the money to invest is money that somebody saved And we're not saving Saving rate is at a 10-year low and Indeed if you dig into the numbers you discover that most Americans don't save at all a Lot of us ain't debt We have negative saving We consume money. We don't even have Who does safe? Who does most of the saving in the American economy? most of the saving in the American economy was done is done by wealthy people Because after you reach a certain level, there's only so much you can consume.  That's okay I have nothing against that and I'm all for cutting everybody's taxes But the fact is from a purely economic perspective Saving is much more important than consumption Investment is far more important than consumption because it creates future jobs future consumption future Goods and products to be consumed What do rich people do with the money they don't pay in taxes they save it they invest it they create jobs So yeah, it's trickle down Yeah, it's flood down That's where we get our jobs So if you want the US economy to do well if you want to have more job opportunities more job prospects you want Wealthy individuals you want businesses to make more money not less To be able to keep more of their own money not less because they're the ones who create the jobs


I am working on health related data sites and so I am using D3 for plotting or developing charts. D3 is a very powerful tool that today Sameer showed us and there are lots of options available in that. Lots of different kinds of interactive charts and plots are there so any kind of data you have you can easily get lots of beautiful insights like you have maybe just a two dimensional plot can show you multiple dimensions by varying the structure, the shape, the size. So it's pretty powerful tool and it can be used for any kind of visualization. So I just plan to use that for my health related data set and see if something interesting comes out of that. Thank you.


Hi guys, it's Monica. Thank you so much for joining me. I'm going to share with you a couple of favorites. So I have some stuff that I know I've talked about in the past, but I have some stuff that is newer to me and I'm just going to share my favorites with you guys. So if you are curious, please stay tuned. Thank you. Thank you. Hey, if you are new to my channel, you just happened upon my channel. I would really love it if you would subscribe and if you've been watching my videos and haven't yet hit that subscribe button, please do so. It'll help my channel a lot. You know, having people watch the videos, even if it's not a ton of people watching the videos, every view counts and of course every subscriber as well. So thank you all so much for helping to support the channel. I appreciate it so very, very much. So favorites. This is not going to be a surprise because this is one of the favorites that I've had for what, since 2016 and that is my collagen. So I buy it in the very big, I think it probably was my last favorites as well. I buy it in the eight pound bag. Yes. So Jay and I use this. We take two tablespoons every morning each and two tablespoons at night as well. So buying it in the big eight pound bag helps a lot. Now, I'm a creature of habit, right? I mean, there are many other collagen supplements out there. You can use whatever you want, but obviously I really like this. This is Great Lakes. It does not have a taste to me. It has some collagen in it, a lot of collagen in it, peptides. It's not full of all sorts of other additives or fillers or anything of that nature. I really like it. It's unflavored. And to me, that is the most important part that it is unflavored because I don't taste it. I can put it in a smoothie. I can put it in my yogurt. I can put it in my coffee. Usually it's in my morning coffee and then in the afternoon or in the evening. If I'm going to have a yogurt or whatever I have for dinner, sometimes I put it in there as well. I can also drink it with just water, but I don't. So collagen, I think if you are on an aging Grace Volley or anti-aging bandwagon at all, then collagen has to be in your routine. And it has to be something you do consistently. Like I say, I am so consistent with my collagen. I've been doing it since 2016. I'm 69 years old. I didn't start to take care of my skin until I was in my 60s. So to me, it was like, man, I got a lot of catching up to do. So I'm very, very consistent with that. The other thing that's my favorite, this may or may not be a surprise to you, but I've talked about this is Candy Way. This is their external glow MD face mask. Now, I know you've seen a ton of different face masks out there. I just turned it on that people talk about. I'll tell you, I've used this now. It's been a month and a half, almost two months. I'd have to really look it up, but I have this by my bedside. So when I get up in the morning, I put this on and I just, I don't even have to strap it on. I lay it on my face, plug, you know, turn it on for 10 minutes. Then I move it down to my neck because I'm trying to do my neck and I try to do my hands. I wish they would come out with something for the neck. I know other other face masks do, but I just really love this company. They are a small company. I love everything about this company. So I'm waiting for them to come out with it. I've used this four to five times a week since I received it and I've charged it one time. So it holds a charge depending on how often you use it. Of course, on my second month, when I started to add in my neck and my decolletage and my hands, I've been watching it. I'm going to have to charge it. All right.  So, you know, it stands to reason, but the charging goes pretty quick.  It plugs in. It's easy to keep clean and a super easy carrying case, which I really, really like. I went camping. I brought it camping and Jay was like cracking up because he was saying, well, people are going to see this red light through the camper window. I wasn't worried about it. Nobody saw anything through the camper window, but I brought it camping because I really like it. I think that it compliments everything I've been doing for my skin. And I think even in the short period of time that I have been using it, that I have seen a difference. I've seen a difference. I put my makeup on with a magnifying, you know, 10 by whatever magnifying mirror. I check my skin with that mirror as well. And I see a difference in my skin. Now, I believe that the I've always believed in red light therapy, but I believe the red light therapy compliments my collagen, compliments everything else I'm doing for my skin. It compliments it. It makes it work better. And when I'm done, when I get up in the morning after I've done it, because like I keep this in my bedside, so you should get up, go to the restroom.  And when I do that, I just pick it up and I put it on. And I sometimes I fall asleep. Sometimes not and I move it. But then when I get up for the day and I do, you know, a light wash, I don't usually have to really wash my skin in the morning. I might rinse it off. I might do a toner or whatever. But that's about it. I really monitor my skin. And I believe that even my scar, because I'm going on one year anniversary from my most surgery on my face. So I have to do an update on that. But my one year anniversary for my most surgeries coming up. And I really think that I'm still using certain products for that. But I really think that the red light therapy is facilitating the healing process or making that scar look better than it has in, you know, in a long time. So without a doubt, my red light therapy mask from Candyway. Thank you so much Candyway is in my favorites. It is it is something that I will continue to use that I love to use. And I will get them neck if they come out with that, I'll get something for the hand. It would just be a little bit more convenient less timely if you can do all three of your body parts at the same time, or whatever. I would also like to use it more on my hair. I've put it on my hair a couple of times just pull it up on my hair a couple of times. So that's going to bring me to my next favorite. My next favorite is a prescription. And it is Finasteride. It's F-I-N-A-S-T-E-R-R-I-D-E. I have five milligrams. This is what I've been using for my hair. I've talked about this a couple of times. It is my favorites. It is in my favorites because they believe it makes a huge difference for my hair. I have not I'm not gone without wearing a topper as as much as I've gone this last two months. I started using this on my birthday February 14th and it works for me. So that is definitely in my group of favorites. The other the other thing and I don't always talk about oh and I didn't bring it in. I was going to I was going to talk about this product that I buy. It's called Awesome. And Awesome is a spray cleanser. Right now I sprayed Awesome. I have a face, a mask, an eye mask that I wear a heated electric eye mask that I put on and and it needed to be washed. So I took it apart and I sprayed it with the Awesome and I just let it sit there and almost immediately I could see a how clean it was coming. So Awesome that product. I get it at like a Dollar Tree store. It's like it's like 99 cents. Right. And I buy it. I probably when I go to a Dollar Store or a Dollar Tree or wherever it is, I always look for Awesome. It's yellow. You can get with the spray or without the spray. I buy the refill size now. And it is an awesome, awesome cleanser. It really is. I should go get it. I'm going to go get it.  But this is what it is. It is LA's totally awesome. This is what it looks like. 99 cents in my Dollar Tree here in New Hampshire. We have no tax. So it is 99 cents in my Dollar Tree. I've seen it as high as like a buck 50 and other stores. But I usually go to the Dollar Store and I get it. This stuff is awesome. I spray. That's why it's called Awesome. LA Awesome. I spray it on a stain.  It was really pretty and it was new. And I somehow spilled. I don't know what it was. Something to do with my fish. It was oily on my top. And I said, oh my God, this is a brand new top. It's going to be gone. I'm not going to, whatever. And I came home. I took the top off. I sprayed Awesome on it. I let it sit. That stinking stain came out. I couldn't believe it. I was so, so happy. So awesome. Definitely. Other thing that has been my favorite this month. This video is going to be super long is I mentioned in one of my previous videos that I'd gone to Trader Joe's and I go to Trader Joe's because I look for the sunblock for my face. They have a super goop dupe and it's super cheap if you can get it out Trader Joe's. But they, I don't have a Trader Joe's near me. So I only go visit Trader Joe's when I'm working in our bed foot office or if I'm up in Portsmouth, which is not that often. But when I went to Trader Joe's, they didn't have this super goop dupe sunblock that I wanted for my face. But I got the body butter. I think I talked about the body butter and I talked about getting this spray on a sunblock. I really like this is Trader Joe's spray sunscreen is what it's called broad spectrum SPF 50. It's water resistance up to what is it 80 minutes. Really good, good stuff. And very, very affordable. I can't remember if this was seven bucks or something like that. Very, very affordable. I really like it. I took it with me camping. It's usually in my motor home. I like that you can spray sunblock when when you use the spray, you can get the back side of you that unless you have someone with you, you're not going to get covered. But this, I really, really like it. And Trader Joe's, yeah, they have some really awesome products. As does Aldi's, by the way, if you go to Aldi's, check out what they have. But anyways, this made my favorites. I really like it. If you have a Trader Joe's, check it out. Also my favorites, not going to be a surprise. My petite and pretty. This is my mascara. I love this stuff. Now, yes, it's a kid's mascara, but it works really nice. Let me show you this. I just got a mascara sent to me not too long ago and I'm filming this. You're going to see this probably a week or two after I film it. But from City Beauty, I have not tried it. I want to see how it compares to my petite and pretty in my essence because my petite and pretty in my essence are my two favorite mascaras. So petite and pretty made my favorites. Here's my replacement for it. I love it.  I also mentioned that I had bought some more of the glass nail files. And I used to always use Emory boards. I love the glass nail files. I love them. Now, they are, they probably do get dull after a while, but I ended up buying myself another set. And it usually comes in two. You've got a bigger one. Of course, I like the purple in a smaller one. And then you have one that you can push your cuticles back with a little round. I can get it out a little round glass that you can kind of push the cuticles back with it. I love these glass files. They, they, I think they are probably, even though my nails are pretty bad right now, because of all the heavy duty cleaning that I've been doing and all the stuff down at my mom's house, they really, I think, treat your nails nicely and make, make them so that when you're filing them, you're not causing further damage. And that to me, I think is super important. I had received complimentary, whoops, from dossier. I know many of you know about dossier. They, they have, they have all sorts of different perfumes. And some of them are dupes for very well known perfumes. Anyways, they had sent me a few to try. And I don't often, I should always remember to mention it because it, it's super affordable. And the sense, if you can find the scent that you like to wear, if you can find it in their line, which most likely you will, you will be surprised at how good it smells. So, so I took this camping with me. And I ended up getting so many compliments, camping, right? Oh, what's that smell? What, what, what perfume are you wearing, et cetera? So I love it. It's affordable and easy to travel with. Put it right in my RV. And the, the scent stays. It doesn't, you know, you put it on hours later, you can still smell some of it. You know how sometimes you put a perfume on an hour later, you don't smell anything. It's all gone. Now this has staying power. And it's not overpowering, at least not the sense that I've used there. There, it's like the right combination. It's absolutely perfect. Absolutely perfect. And that brings me to the built bars. I don't know if I have a coupon for built bars anymore. They used to send me stuff. I haven't gotten anything from built bars in a long time. I love built bars. They're, they're expensive. But they, they don't, they don't mess with me. You know, when I, when I eat a built bar, I actually do feel full. I love a lot of the different flavors and they don't cause me to have any kind of a stomach upset or anything of that nature. They came up with built bar puffs, which is, if you like marshmallow, you'll like a puff. And I fell in love with the built bar puffs. I've tried many different flavors. So I was absolutely ecstatic when in my Sam's Club in New Hampshire, I found built bars puffs. And this is a 12 pack gluten-free, for anyone that's on a gluten-free diet, right? And this is brownie batter puffs in the Curio Buffs. It's a multi-pack. And, and I found it, it's cheaper for me to buy it there than it would be to order it even with my discount and pay shipping. So, um, yeah, built bars, puff bars. I found them in my Sam's Club. I don't know that they're going to be in every Sam's Club because when Jay and I went camping and we were up in Maine, we went to Sam's Club up there and they did not have any. I was looking to see if they had some, they did not have any. And I was, I was like, okay, so it's not going to be in every Sam's Club. But, um, the other favorites that I have is I love, and it's not my Apple ear buds and not my favorites.  But I absolutely love listening to audiobooks. So I have an audiobook account. I don't have any kind of affiliation code or any discount code or anything like that. I'm just mentioning audiobooks. I love listening to audiobooks and podcasts and I will do, I will listen when I'm driving, I will listen when I'm walking, I'll listen a lot. And I use my earbuds to listen wireless. And right now I'm listening in audiobooks. I've got a, a book that I'm listening to, which is probably not going to be anything super exciting for anyone. I do listen to a lot of true crime, but the one that I'm listening to now is a, it's a historical book. It's called The Brothers York. It's a history about the York brothers. They were, one was King, King, well, two of them actually were Kings of England way back in the day. So the York and the Lancasters, the Royal Family disputes that they had with each other. And this talks about Edward when, you know, when he became the King and he married Elizabeth and then his brothers, the Duke of Clarence and, you know, his two brothers and Richard of course, ultimately his brother Richard also became King. So it's the history from of that era. And I am really enjoying it. It's written by someone named Thomas Penn. I've never heard of this person, but I'm sure he's done tons of different books. It's an audiobook. I just really love listening to this stuff. And now I still have 14 hours and 54 minutes of listening left. Can you believe it? And I've listened to 25 hours of it. Yeah. So you can see I listen and multitask and do other things. So my audiobook subscription has been an ultimate favorite of mine. I'm so glad I have it. If I didn't have it, I would be listening to a whole lot more podcasts probably, but I do listen to a lot of podcasts. I'm back in the groove, you know, as much as possible. So trying to record and trying to listen to audio books and trying to, you know, listen and catch up on my YouTube videos and all that stuff. So monthly favorite for sure. I had purchased this mirror. This will be my last thing I'm going to talk about. I had purchased this mirror. I don't know when it was now. I really like this mirror. It's a compact. One side is 10 times magnified. The other one is normal, right? So if I look in the 10 times magnified, I can see, you know, pretty well every line, every nook and cranny.  But I really love it. It lights up and everything. I bought it. It's got a couple of different modes for the light. So you can have a brighter light or duller light. You know, it's really nice. I bought this for traveling because I find sometimes, you know, during the day, I want to take a look and fix something. And I need that magnifying glass, you know, with me, that mirror. So I found this compact to be awesome. I've used it more and more and more, especially this last month because I've been gone a lot, been down my mother's, been doing this, been doing that. So this, the one I have is Noia N U-O-Y-A. And I got it off of Amazon. I love it. So this definitely is hit favorite. So after this, I think I'm going to probably try to do a video update on my most surgery because it's going to be one year. And just talk about that. I've had a couple of requests to do another look at my skincare. But, you know, I really haven't changed a whole lot. I mean, I've added some stuff, but I really haven't changed a whole lot. So we'll see. But thank you so much for watching my favorites. If you're new here again, or welcome to my channel, please make sure you subscribe. And for all of you, my friends that watch all my videos, I appreciate every single one of you. Thank you all so much. You guys have a wonderful day or weekend. I don't even know when this is going to go live, but you have a wonderful rest of your day and rest of your week. And I'll see you in my next video. Bye-bye.


Dear students, in this topic we shall discuss the arterial chemoreceptors in detail. The arterial chemoreceptors are located in the carotid and aortic bodies. They are primarily important in regulating ventilation, i.e. breathing rate, but they are also important in cardiovascular system due to its close relationship with the respiratory system. The arterial chemoreceptors monitor chemical characteristics of the blood. They respond to an increase in the concentration of carbon dioxide or decrease in the oxygen level and pH level of the blood. They help to regulate the functions of both cardiovascular and respiratory systems. Now we shall discuss the effects of stimulation of arterial chemoreceptors. The stimulation of arterial chemoreceptors due to increased carbon dioxide concentration has direct effect on heart rate and breathing rate. Heart rate and breathing rate increase when arterial chemoreceptors sense that the level of carbon dioxide is high in the blood. As a result, carbon dioxide is eliminated rapidly from the blood. Arterial chemoreceptors slow down the heart rate when the animal is breathing. This effect causes peripheral vasoconstriction while the cardiac output is reduced. Peripheral vasoconstriction results in increased arterial blood pressure which maintains blood pressure in the arteries leading to the brain so that a blood flow to the brain is ensured.


Thomas has a major question. So prepare yourselves. Is it possible to add an Outlook public calendar to a team? Yes. All right. Thank you for watching. How do you do it? There's the button on a tab. You can just add a web page, get the link from a browser because ultimately, it sits in a through a browser as well with that with Outlook and drop it in that way. But I think what they're trying to do is on calendar, be able to show it in calendar, but the calendar is your personal calendar. So yeah. Yeah, that's the happy widget. The little one-size-fits-all tool in the toolbox is that web one because everything has a URL and you can just paste a URL and put it on a tab. That's all. I love that. I love having that web one there. There's so many things that's so cool to plug in. Yeah. GCC didn't have that. I don't know if they have it now, but they didn't have it. They couldn't add anything to a tab using the web. So the government might not be able to do that. Well, right. Well, because they don't have access to most sites that are public. I lock it out. Yeah. It does. It comes down to what's been turned on or off too. Yeah. Absolutely. Yeah.
