Both of them off and away Derby out front in the pickup truck right hand side And Derby goes 1098 at 123 Roush goes 1304 at 107 We're up here at the rock Got Zorro going down the track First time for that car we got David Christie's Ram up here a project storm over here About to have a big change We got frostbite as always I Got you on the tree fam. I hope everybody's having a blessed day out there We are in North Carolina at the rock We are drag racing and we have all the toys up here today We have the new challenger Zorro up here my son I'm letting my son drive Zorro and we are getting it down the track for the very first time Obviously There she there it is and then we got frostbite as well We got frostbite up here, and we are completely full weight. I didn't take anything out of the truck this weekend We have literally everything in you can see floor mats carpet center console Both seats door panels rear section Even the toolbox case in the back no nitrous the dash Reel doors mirrors Everything so and my rear tires are just about shot by the way. We need new tires I did just put new tires on the front the weather is not as good as I was hoping we're having we're fighting in the mid to low 2000 da's So we're not running. We're not running 10s right now. We're running. We're close. We're right there on the 11 So We're doing pretty good, but we're running the himmy shootout class now Zorro I will say has completely impressed us The new Challenger. I just bought this is a stock 5-7 car. It's a 14 Nag 1 car. We still have the 20 inch street tires and wheels on this car front and back It still has a stock air box set up And this is the plus package car. So we have leather. We have a sunroof. We have heated seats We have everything in this car the back seats still in it like we didn't we drove this car all the way up here six hours My son drove it to come and race it We even have the spare tire in the trunk because on these tires It's helping it hook up and it's actually doing very well This car has custom carnage exhaust all the way back X-pipe with their performance racing mufflers I Did change the tune a little bit myself as you guys know we did the little ghost cam tune in it Which doesn't do anything for performance. It's for sound only, but I did add a little bit of timing on the top end of The tune so it picks up pretty good on the backside He ran 11 or excuse me He ran a 13-1 in this car just a second ago again about a 2,000 da at about 105 miles an hour That's honestly, I have never seen these older challengers Run that well Ever like most of times most of the ones I usually race they seem to be you know fighting the low 14s or high 13s Especially on stock tires and everything not really messed with so I've had a lot of people come up to this car and They're really shocked how well it's running and as we are we're completely floored how well the truck How well the car is doing Zorro is definitely putting up a fight so That car is gonna be pretty interesting when we get a drag pack and you know real custom tuning on it storm is up here On the new tire package smaller tires and wheels the circle D converter Again, we don't have the air That we wish you know the negative da's are gonna be gone for the rest of year So it's gonna be a while before we really get to see what this truck can put down in and good weather But we did break its personal best today in this hot weather and the truck ran a 13-5 So it's a tenth quicker in the heat than it was last year So that's definitely definitely a plus Considering last year it was a tenth slower in a fight in a negative 500 da so I'm assuming when we get the negative air back The truck should be capable of probably running 13.0 is maybe a high 12. I don't know we'll see but it's definitely running pretty good and It's also full weight as well He is running this thing Full interior He's got the door locked right now the back seat is still in the truck.  So only thing going on tailgates off And it drove all the way up here six hours to come race as well. So pretty cool We got David Christie's truck over here the old Pickle truck we call it long bed regular cab and This is an NA truck and he's pretty much all full weight except for the same seats that I have in frostbite And this truck runs good for NA with a converter and a 545 He's running 1320s in today's heat so pretty good and I Think this truck right here and this guy right there and that black car over there Zorro is gonna have a good battle for 13s today. I Am yeah for sure So yeah guys there it is this is our little camp area for today stay tuned hopefully between All of us somebody does good and we do something or win something or You think you're gonna win the 13 class Well, if you win the 13 class in my car that kind of counts actually means that I won it, right? Because it's my car Yeah You're just winner by dinner. You're just a driver. So technically my car guys David said he's gonna sandbag so he can buy dinner if he wins He needs a win right now Right now he's doing pretty damn good. So I gotta say the car and him's doing something right So wish us luck stay tuned.

So nothing wrong with that I tell you the one thing the one thing you have down here, though You've got you got the best view of you know the starting lot Yeah, absolutely Somebody like doing me that is taking care of Doing certain things when it comes to not only race relations being a part of it working behind the scenes It does give you how much great stuff comes out of one event in the next in like three to four days The amount of stuff that comes out of it is amazing a couple of good passes there 1112 for Dylan Derby Joe Edmonton going 951 at 146 in the Halcat Challenger out of another one out of Georgia Seems like there's a lot of cars out of Georgia But I see a lot of people coming out of Rockingham, North Carolina the surrounding area so heavy favorites here Obviously everybody likes to show up and support their home racetrack speaking of supporting They're giving away a set of pistons today, and they were like maybe maybe you'll you'll call the person who wins They're gonna give us a list of names.  We'll give them a set of pistons. Oh, I'm in maybe I mean I mean like you know when he said he was giving away a set of pistons earlier I was trying to hand the mic to somebody else so I could go sign up for him, and he didn't look enthused He was like wait a second. No, that's my job. I need to leave you need to stay here So They're the winners, but yeah Right, yeah after the second session now tell me how you think this would work Let's see if the person has a sense of humor.

Hello everybody! From this video, you will learn how to safely keep, save, backup or recover lost files created in Adobe Photoshop, Adobe Illustrator and CoralDraw. Adobe Photoshop, Adobe Illustrator and CoralDraw are very reliable software, but as well as other programs, they may encounter errors and failures that are not necessarily caused by their own internal reasons. It often results in loss of the file that the user has been working on. So in this video, we will give you some advice on how to prevent such losses or recover an already lost Adobe Photoshop, Adobe Illustrator or CoralDraw file. Hello friends! If you need to recover deleted data, view or restore removed browsing history. Hetman Software products will help you. Follow the link in the description. Download the necessary program for free. Install it and analyze the disk. The utility will show you the data you can recover, so you will be able to view it or get it back. In our channel and blog, you will find solutions to any problem, from installing an operating system or configuring it, to fixing possible bugs and errors or optimizing mobile gadgets. Our specialists will answer any questions you ask in your comments under the videos or articles. Let's begin with the leading commercial software for editing bitmap images and the most popular product by Adobe – Photoshop. When starting your work with Photoshop, remember that you can't prevent a software error or a failure, but you can prepare for possible problems. You can save a file regularly by using the menu File – Save, or pressing the key shortcut Ctrl-S. Yet there is a better option. To set up Photoshop Autosave function, in order to enable and set up this function, open Adobe Photoshop and go to this menu – Edit – Preferences – File Handling. In the menu that opens, check the boxes next to Saving Background and Automatically Save Recovery Information and set a period of time. This Saving Background function lets the program save files automatically without distracting you from work. If you enable this function, the default Autosave time will be 10 minutes. However, a lot can be done for 10 minutes, so it's better to set the minimal time period – 5 minutes. If you set up the Autosave function properly, you start Adobe Photoshop after a software failure or freeze, and it suggests you to restore the latest Autosave file or just opens an Autosave file in a window next to the one you are trying to open. But it doesn't happen with that way quite often. In this case, go to the folder in Drive C where Photoshop keeps Autosave files in the PSB format, which is basically the same PSD file supporting large file size, which can be opened with Photoshop. You can find this folder by following the path C, users, username, app data, roaming, Adobe, Adobe Photoshop, auto-recover. Go there and you'll find a PSB file for automatic recovery of the last Autosaved copy of an Adobe Photoshop file. If you select the details view, you can see the time when every Autosaved file was created. Now let's talk about Adobe Illustrator. Working with vector graphics in Adobe Illustrator is a long and tedious process. That's why for cases when quite a lot of time was spent working on an illustration, and the final result is not exactly what the designer wanted to have, there is a function of returning to the last saved version of a file. In order to use it, just go to the menu File -> Revert. As a result, the picture will be returned to its condition at the time of the last save. Changes made after that will be canceled. Similarly to Photoshop, Adobe Illustrator has built-in tools to restore an unsaved illustration after a software or computer failure. You should set up this function to be able to use it effectively. To do it, go to Edit -> Preferences -> File -> Handling and Clipboard. In the Data Recovery section of this menu, set the intervals for Autosave Recovery data, ranging from 30 seconds to 60 minutes. And the folder where to save it. By default, this folder is C, Users, Username, AppData, Roaming, Adobe, Adobe Illustrator, Settings, X64, Data Recovery. Now if there is a software failure or if Adobe Illustrator suddenly crashes, the program will restore all Autosave data after you started the game. The Autosave file has an extension AID and looks like this. If for some reason the program doesn't restore any illustration from an Autosave data file when you started Adobe Illustrator, you open such file manually with Adobe Illustrator. In this case, the Autosave illustration will be restored in Normal mode. When working in CoralDraw, you can also encounter problems with software failures. How can we prevent data loss? It is just for these such situations that CoralDraw has an Autosave function. To make it more effective, you should set it up. That is, decide on the time interval and location where saved copies will be stored. These settings are available in the menu Tools, Options, Workspace, Save. Of course, the shorter is the time period between autosaves, the less data will be lost in case of failure. However, all should be in good measure. Your instance of saving a document takes some time, and the larger the document, the more time it takes to save it. The best Autosave time is 10-15 minutes. You should also specify the folder for autosave files. At the set periods of time, automatic copies of your files will be saved into such folder with the extension CDR. If anything happens or the program crashes unexpectedly, you can also always go back to the last autosave file. Just open the autosaved copy of your file. Besides, in this section you can allow saving backups. The backup on save option allows saving the latest version of a file before saving the actual file. Backups also come in handy when recovering documents. If the autosave function was not set up at the time of an unexpected crash or software failure which resulted in losing an Adobe Photoshop, Adobe Illustrator or CoralDraw file, such file can be restored with special data recovery software supporting file formats such as PSD for Photoshop, AI, EPS, AIT, SVG for Adobe Illustrator and CDR for CoralDraw. There are only a few products that can help you restore these particular file types. If your illustrations were lost after a software failure or for other reasons, you can always have them back with Hetman Partition Recovery. To do it. Run the utility and scan the media where illustrations were saved. To recover the illustrations you need, drag them to the recovery list or right-click on them and click Recovery. Specify the location where to save files and click Recovery. The files have been recovered. In the same way, you can also recover autosaved copies of files with extensions like PSP, AID or CDR. That is all for now. If you found this video interesting, click the Like button below and subscribe to our channel to see more. Ask questions in your comments. Thank you for watching. Good luck.

What's up everybody, Jason here for jazby's case breaks.com. This is our last little filler here for the six six spots in the dual case impeccable Football break. We're giving away in 2020 mosaic cell a football pack break Number 63. So again guys first we'll randomize the customer names and teams Distribute the hits out of the pack break and then at the end of the break We'll randomize only the customer names from Ryan down to Brandon and Customers in the top six will win a spot in the dual case break to become our next in a separate video So good luck. Let's roll and we got ourselves a two and a five seven times. Good luck one two three four five six seven Oliver done a Robert Five minutes two two and a five seven times one two three four five six seven seven times Falcons down at the Minnesota Vikings Alrighty seven times seven times So you got stick to what you got guys.  Let's give away the last six spots Good luck roll Three into two five times guys five times right here Good luck top six get in one two three four five boom Two and a three five times from our top six Robert Victor Adam Brandon Jake and Nick Stover Five times and it was a lot top six right Yeah, six of them Well, congratulations guys last six in next breaks coming up next


So in the equation, there's somebody that makes music and there's somebody that puts up money and takes a risk, right? Well, the person taking the risk is seen as more valuable than the art than the music itself And I have a problem with that because a rapper signing to a label is taking just as much risk That these people will know what to do for their career and get them to the next level as the money is taking on The artist and hoping the artist won't self-destruct along the way or will make Music that fans will want to hear


Over to you, Joe. Let me stop sharing. Okay. Thanks very much, Marana. Really, really a wonderful overview. And I think you're making a great, great impact there. If anybody has a question, you can, I see Susanna. So, Susanna's right and Melcho. Okay, so I'm just going to go the order I saw them. So, go ahead, Susanna. Are you okay? Are people's hands going down now? No. Yeah. I was just, I just wanted to give compliments to Marana. Thank you, Susanna. Thanks a lot. Okay. Melcho, did you have a question? Okay, there is another person, Henry. Okay. There is a yes, Henry. Okay, Henry, you can unmute and you can ask, please. Thank you. Just want to comment that was a very motivating presentation. In fact, when I joined the course, I didn't have in mind this other role that we should have as a professor to continue. I'm not a radio frequency person, but as I said, I, for my former education, I thought also optics, and I knew that the optics, he also has a lot of support and also perhaps as part of, in one part of the course, I would like to request that maybe you can share some of these opticals back that were offered, I think, in time when I was studying in which they contain many types of experiments or what type of materials you were using. So anybody in other parts of the world can replicate these efforts to promote optics and of course to promote that young students get involved in science. Thank you for motivating and congratulations for this good label in Rana. I really was motivated for your presentation. Thank you so much. You know that for LIDAR, it is your, as you mentioned during the introduction that you are working on LIDAR. So we decided to do a hands on activity on LIDAR, but you know all the equipment is very expensive. We made some models and today we did an activity based on those models. We explained on a board, the working principle of LIDAR, RIDAR, SONAR, everything, but I made a toy kind of models. You can give, and I can share everything with you online. If you use, I will take your email address from Professor Nevela and we can do that. Thanks for your nice comments. Thanks a lot. Okay. Well, thanks. I'm going to take, we can take one more comment from Hannah and then we need to move on. Now, as usual, I want to reiterate in Rana for this wonderful work that she's doing. The question is, do you have the sensation that all this activity has already produced some more feeling of the students for optics and science. Do you see a result? Yes, Rana. Let me comment because there are, we visited Fatma Janal University couple of times. So we repeated and we have the feedback we were doing the follow up of those activities. Similarly, with some government colleges, we did kind of follow up. So now, as I mentioned that in, this was my first activity in last April when we went to a primary school. It is not a right age to enjoy the right kind of optics activities, but that was really, really, we, it was me and Abdul Rehman on me. Those girls, we have, girls were 70 and we have 10 reflect views to draw an image. They wanted to grab one reflect view, the force and everything to learn and hold off those things to do it by themselves. It was really, and we will go to them again by the end of this year to see how they react to us because in the beginning of that activity, those girls were very shy, very close. And after two, three hours, it was fun to be with them. And similarly, with the different girls, it makes a difference. But there are so many schools, so many colleges, so many to do. And we are not able to visit all these institutes every year. Because last two years with pandemic, even I tried hard to reach out to many universities and this thing but it is still not enough. We need to do and move on from lower level to higher level and then see the result. That sounds like a very general theme for all of us. It's so much to do and so little time and resources to do it. Absolutely. So thanks very much and Rana for wonderful presentation and keep up to good work. I can't wait to get back to Pakistan. I'll bring my camera. So, okay, so John Freddie is here and let me let me just introduce it really quickly. So John Freddie Barreira Ramirez. So he's a professor of physics Institute of Antioquia University probably killed that in Columbia. He was I see ICP Galliano Donato awardee. He's a regular associate of the ICP one of the 30 scientists out of under 40 years old that are doing promising research, which was revealed by Latina Latin America science. He's the most optic senior member SPI senior member. And he's part of the young affiliates network of the World Academy of Sciences. He's won many awards in Columbia, National Research Awards. And he's got two patents as well. So he's been very active and he's also coming here to ICP. So I'm looking very much forward to seeing him again in a couple of weeks. So John Freddie. He's going to talk about optical encryption and optics in Columbia. And so anyway, I'm looking very much forward to your talk and I'll hand it over to you. So you can go I think you can share your screen. Yep, I can hear you. Okay, you can see my presentation. Yep. You need to go into presentation mode but. Okay. Me. Okay, sorry. Okay. We're in the afternoon or, or morning, depending on where you are. My name is John Freddie. Professor of the physics Institute at University of Antiochia in Medellin, Columbia. I am also regular associate of ICTP. The purpose of this talk is present the work that we have done in optical encryption, and also I would to present the state of optical research in Columbia. Okay. Okay, I live in Columbia here in the city of Medellin. Here you can see a view of my part of my city. The main campus of my university is here. Near to the Medellin River. And this is part of the metro system of my city. I'm the coordinator and the opposite of the group is taking this this photo was taken recently in the main campus of my university. It was a cloudy day.  Here we have the most members of my group. We are six teachers with his own undergraduate and graduate students on here. You can see the members of the research line on optical information process. About a system, as you know, including system allowed to, to protect information, but over the years, many of the criticism that we're originally talked to be secure, but by finally rock. Why we talk about optical inclusion because optical inclusion offers some advantages. For example, the processing is performed at the speed of light. An optical system provides several degree of freedom like polarization, whether in our face, and the most important thing we use a physical key, instead of a digital key, like a digital protection systems. The basic definition of a crystal is why it's quite simple. In the process to convert one data in an encrypted image is encrypted image is a nonsense pattern. And this work is done with a decryption system. This encryption system contains a key element called security key. This element allows to convert the information in the encrypted image and also recovered when you have the security key. And the decryption is the process of converting recovering the information from the encrypted data. In that way, you have encrypted information and the security key. Using both data, you can recover the information, the security of the process. And based on the following idea, if one user intercepts the encrypted information but doesn't have the security key, the information cannot be recovered. It still remains hidden. In this way, this is the system protects the information. The fifth proposal of an optical encrypted system was the double random tracing coding technique. It was proposed in 1985. The system was implemented in a 4F architecture. You can see this encryption system contains two lengths of a current F1 and 2, a two random face mask, one random face mask in the input plate and the second random face mask in the first Fourier plane. If we insert the object in the input plate, I illuminate the system with a plane wave. In the output plane, we update the encrypted data. You can notice that the encrypted data is a noisy pattern due to the use of the two random face mask. The encrypted image is then the information, the convolution between the information in the input plate with the Fourier transfer of the security key. Then the decryption system is also a 4F system. It's a 4F system because it contains, because the distance between the input plane at the output plate is 4F, where F is the focal length of the lens. For the encrypted information, as I said, we use the encrypted object, in this case, the complex conjugate, and in the first Fourier plane, we place the security key. With both data in the output plane, we can recover information. In this way, we can use a 4F system with two random face masks to encrypt and then decrypt the information. Once we can encrypt and decrypt one data, the next step is encrypting and decrypting multiple data. How we can do using multiplexing? Suppose that we have n objects for O1 to On, we encrypt each object in the system individually, and then we obtain each encrypted data, E1, E2, Em. And then we add all the encrypted data in only one package. This package is called multiplexing. What is this? They say you have all the encrypted data in only one that's called multiplexing. Now, how we can recover the data? It's simple. If you obtain the multiplexing, when you use key 1, you recover object 1, and the other information remains hidden. And the same if you have the multiplexing and the key 2, you can recover object 2. In this way, you can send this multiplexing to any users, and each user with one only key can recover only one data. This is the purpose. Send all the encrypted information in one package, and each user only recovers one data. But we have a very big problem when you manage multiple encrypted data. For example, in Figure E, you can see one object that was decrypted and encrypted using the 4F system. But in Figure B, you can see one object recovered when we have the multiplexing of 30 objects. If you have the multiplexing data, 30 objects in the multiplexing, and I'm trying to recover one of the objects. First, we obtain the recovery of the audio, so I can see here in the background, but the 29 non-recovered objects introduce noise on the recorded plane. In this case, you can notice, you can distinguish the object because the noise do it to the other objects. This was a very hard problem for optical increases because set a limit on the number of objects that you can encrypt and decrypt successfully. Now, we found that we can solve the problem modulating the encrypted objects. What is modulating? It's quite simple. We have the encrypted data. We multiply this encrypted data by a sinusoidal rating and we obtain an encrypted and modulated data. If we apply a Fourier transfer over this data, we obtain the diffraction orders where the diffraction orders contain the information of the encrypted data. We are going to use this concept of modulation to encrypt and decrypt successfully multiple data. In this case, suppose we apply this process to encrypt a movie. As you know, a movie is a sequence of frames, projectically set a frequency. We have here the frames from F1 or FN and we encrypt all frames using the Fourier system. We obtain U1 is the encrypted frame F1. GN is a rating and we will multiply the encrypted object U1 by the rating GN, G1, we obtain an encrypted and modulated frame. In this case, we can do the same for all the frames and then we add together all these modulated encrypted objects. Then the encrypted movie is only one data. It's the adding of all modulated and encrypted frames. In this case, we have only one data, the package with all the information encrypted and modulated of the video. For recovering the video from this multiplexing, we applied a Fourier transfer operation here and in the Fourier plane, we obtain the diffraction orders. Each diffraction order contains the information of one specific encrypted frame. In this case, we filter each of the diffraction orders here and after a Fourier transfer, we can select each encrypted frame. In this case, we obtain the complex conjugate of each encrypted frame. We can extract from this multiplexing each encrypted frame without the superposition with the other frames. Now, simply, we use the Fourier decryption system and recover all the frames that were encrypted and modulated. In this way, we can encrypt a lot of frames, a lot of data and recover it independently. In that way, you can recognize every object in the movie. Now, in 2011, we published the first video encrypted optically, probably optical means, here you can see the reconstruction of the video. Look at using the right decryption process, but if we use a wrong key, look at this, we cannot recover the object. The movie is still encrypt. This paper was covered for the spoilers on the section of optical society. Then, we extend this procedure for encrypt color movies. You can do it for each channel and encrypt movies in the same way that you can do it for one movie, like that. Look at this. There are several systems. We saw it for a system, but one of the most used encrypt architectures are the JTC. If you look at the system, this is a two F system system is the because 12 is the distance between the input object input plane to the recording plane. We use a single lens F and in the input plane, we have the object multiplied by a random face mask and a random face mask that consists of the encryption key. If you apply if you illuminate a plane wave. In the Fourier plane of the lens, we obtain the jump power spectrum, we can record that spectrum, for example, with a CMOS or CCD camera. And processing this unit jump power spectrum we can obtain the encrypted data. Here the crypto that is the product between the Fourier transfer of the object by a random face mask. And the Fourier the conjugate of the Fourier transfer of the security key. Here we have the encryption information, but when we need the information of the security key for doing so, we block the information of the object, and we use a reference arm to obtain here the hologram of the Fourier transfer of the key. Then we use a single arm to obtain the encrypted data, but we need an interferonical arrangement to obtain the hologram of the Fourier transfer key. The decryption system is also simple is a 12 system in the input plate will put the encrypted image on the Fourier transfer of the key and in the plane key, we obtain the decrypted data. This is another way to encrypt and recovered information. Then we extend the first proposal of one movie to encrypt multiple movies, for example, we have three movies, we encrypt the first and the last movie, we know one key. And then we encrypt a term movie, the second one here with other key. We add all all these encrypted movies together and look at here here in a the recovered with the key one. We can record the first movie. While the second is still hidden. And the last one can be recovered. On the reverse on the contrary. We use the second key. The first movie is still encrypted. The second is recovered. And the third one is still encrypt. We, we, we publish a lot of a practical applications, one of the most interesting is this application where we are protecting messages or of any length. We use one optical key, what we do is is encrypt every character of a keyboard. Then we multiplex all characters and then using the optical key, the security key, we recover the keyboard in this case is the keyboard and using a select selection position key, we can recover any look at here and suggest information security to light. The security is of the system is covered by the optical key by the random key, but this selection position key allows to recover any message of any length. This work was selected like highlights of 2013 for the number of optics, and also was included in IOP select in IOP platform. We demonstrate that this is possible to include from a single character, structured objects, one movie, several movies, color movies, the messages of any length. But you can see here, you can notice that all recovered data has noise. This noise is a very big problem because users, one user requires safety, this is the optical system provides safety, but high fidelity recovering. We need recovered for example, this photo, but without noise. The optical system uses random face mask and does random face mask produce this noise. Some researchers try to reduce this noise, between them also, using optical and digital techniques, but no of the proposed methods allowed to removing this noise. We were working at least 10 years trying to remove this noise, we can reduce this noise, but we can, we couldn't remove it. But the answer was knowing the optical of digital techniques, using for optical, optical digital processing. The answer was in the quick, in the quick response calls, the QR codes. Now they are very popular, but in 2020, they are very popular, but in the past, we're not so popular. Now, they are, they are two dimensional barcodes employed to store information. These QR codes were invented in 1994 to trap vehicles during manufacture and has a lot of advantages. They are fast reading, they are tolerant to noise. Be careful with this, tolerant to noise, loss and misalignment. And the most important thing for us is the use of QR codes is free of any license. You can use it and there are no license. Look at this idea. We have an object, optical encrypts. If you use our system, you can recover, you encrypt and decrypt the data, but the recovered data has noise due to the processing with random face mask. Or the idea is combining optical encryption and QR code. Look at this. Optical encryption was proposed in 1995 and QR code in 1994, but for different purposes. Here, what we will do is the data is converted in a QR code and we encrypt the QR code instead of the information here. In the emergency, we have the encrypted QR code. If we apply the crypto process, you recover the noisy, the cryptid QR code. But as I told you, the reading of these QR codes is tolerant to noise, you can recover from this noisy QR code, the original information without noise. If you apply the conventional procedure, you recover the information that we did this noise. In conclusion, if we use optical encryption and QR codes, you can protect information and also recovered free of any kind of noise. This, this work was published in a business press and was covered by nature photonics in the station research highlights with the, with the article, quick response codes. We also prepared a patent of these of the system called of the physical apparatus and procedures for encrypting information and it's covering, recovering free of noise. In this point, everything was done from the point of view of basic research. Here, you can see a movie of the optical setup in my laboratory in Medellin. Look at the typical elements mirror polarizer, and it's possible to project the information CC most CC most camera on mirror polarizers. And after this work, we decide to make a prototype of this increase the system here is up to view of the prototype will all the elements involved here. And in this video, I'm going to show you the prototype look at here. The optical system is here in this black box. And the idea is that you can control all the system without one software we develop. This is again, at the view of the system. Here you can see the components is the system is a complete version of the setup that we use for basic research with almost the same elements. Here we can see some difference, but in general, it's almost the same setup. The polarizer here, polarizer here, mirror, as a most camera. And there's a change here, the previous system is a digital micro mirror device is the special line modulator is a less costly elements. We construct a generator of an office mask. To register the optical key. As I said, we prepare a software that control the the optical system, we can insert the information for example here for the computer you can insert alternative GTC. This is the message you can protect and the system generates the corresponding QR code. Then, we encrypt the data using the optical system and obtain the security key. Then, with both information, we can record the original data. This works in several domains for your fractional. Here are some parameters you can change, but in general, we decrypted that of the security key. Due to the script, the QR code, after reading the QR code, you can recover the information free of any kind of noise. This has a lot of steps. It wasn't easy from the basic research to a prototype for me was extremely difficult because we never have the experience to things like that and it's very difficult. It was very difficult for us. Okay. On summary, we start to encrypt single data like a character, for example, the letter e to more structure objects like QR codes. Also, we create we create new codes, new codes for recovering information free of noise. Also, great scale information. We pass to color information. And in these days, we were able to encrypt and decrypt color and structure information here. To the right, you can see the record the decryption of a movie or a real movie of a 3D and color object. Look at this. It's a three dimensional object in color. Here, here you can see the evolution from a single letter to a real to a real movie. Our last, our last contribution is a compact increase in system. Take, take attention, look at for the JTC system, we use one setup to obtain the data is only and only one, but if you want to record the security key, you have to use an interferometric arrangement. You have to add this arm, this reference arm to the system. Okay. What is our idea. We want to record encrypted data and the encryption key using a single arm setup for in both cases, look for recording encrypted data and then a recording encrypted key. We propose a published one contribution, then the way we show that it's possible to encrypt and to record the encrypted information at the security key with a need for a reference arm. What we do. What's simple. When we are projecting the information of the security key. One window that acts like, like a reference arm in this way we can record, record encrypted image and security key using the same system. One arm system results in a significant decrease in the size. The quantity of elements, look at this, look at the setup, the size and the, this is all the quantity of elements do it to this reference arm and the setup that has a reference arm. The results that in a decreasing of size, the quantity of elements and the complexity of the system. And I want to say you that you can do basic research with low cost setups. What does mean. It depends of the pocket, but the local setup, for example, you can implement this setup with buying the components in an appropriate place, maybe by 3000 to $4,000 and you can do basic research with this money. But the biggest thing that you need big, big labs with a lot of elements, not always, not always, sometimes it's possible to do good research with local setups is a message that you are going to receive in the next talk with my friend on birth. At this point also I want to, to say that we have a scientific collaboration over group with the ICTP of the laboratory in the frame of the program field is a program for training and research in Italian laboratories under under this this program, one of our students was in the ECTP of the laboratory with Umberto and Joe, they, they, he was there two months, trying to, to combine optical encryption that is work or topic here in Medellin with the topic of Umberto and Joe in ICTP lab, that is, in 2008. And after two months of working there, my students, we were able to publish the GR, this paper in Journal of Optics, Optical Increase Using Modulation, Generated by Thermalness Effect. This is opportunity for you if you want to, to work in research maybe apply to this time of programs that are very, very useful for home for young researchers. I'm going to, to use the last part of it, my talk to, to talk about the state of optical history in Colombia as an asymmetric analysis. This is very important, because you never know how is is working your country along the along the years, and this study was published the year, and it's very interesting. This study were determined using the research articles published by authors with Colombian affiliation in journal index in the scope of database, or was taken from the scope of database belonging to atomic and molecular physics and optics to this category. These are important facts, even for me, the first work in Colombia in this topic was in was published in 1973. We have two periods, 1944, 1979 and 1981 to 1988 with, without publications. For 1999, the publications climb rapidly until 2000, 2002, when we have 135 publications. Here, we can see the optical research groups. The first group was created in 1972, it was our group. From 1973 to 1979, no group was created in this period. Most groups were created until 2005, where the number of the new groups start to decrease. And these same frames coincide with the return to the country of many Colombians with PhD in optics or related areas. For example, in this, in this time, in the same frame, a lot of researchers that were to do the PSD. Alongside, they return to Colombia and start to publish. Here is the distribution of the groups in Colombia, we have 61 groups in optics on related areas. Look at here in red, we have the group from 2003 to 2010. You have most of the group here, look at where created a lot of group in that time from 2003, 2010, and from 2011 to 2020 start to decrease the number of new groups. You can see the groups are concentrated in the most concentrated administrative departments with more gross domestic product, the biggest departments were populated. For the general productivity between 2016 to 2020, we can see that in 2016 were published 114 while in 2020 we published 202. It was an increment of 77.2%. The productivity increased beer year per year with an average 169 per year from 2016 to 2020. Another important fact, look at here, the percentage of international collaboration in 2016 was 64.9 and in 2020, 61.9. This international collaboration was above 60% except for one year. And the percentage of output in Q1 for 2016 were 20.2 and for 2020, 30.2. It was a huge increment here from 2016 to 2002. These institutions contribute with more than 50 papers. This is institutions have their green campus in the three administrative departments with most of these are for the research groups. Look, look at this, the first University of National Columbia and University of National Antioch are public universities. The University of National Columbia is the biggest university in Columbia and it's a national university and University of Antioch is a departmental university. Look at the number of documents. Also, the University of National Columbia publish 2.6 times more documents than University of Antioch. The University of National, the Columbia. Look, look at here the value 6.513.13 has half as many citations per document than University of Antioch. You do say that the impact of the documents for University of Antioch is superior. Look at this, this is that top seated documents in patents between 2011 2020. You can find here. Come on from the society, optical express of the letters and applied optics. But it's interesting to note that there are three contribution in proceeding of SPI showing that this proceedings has a high impact in technological aspects. Now, here, look at this interesting slide. But 30 journal with most policies articles between 2016, I'm sorry, between 2016 to 2020. You can see here, the classical journals from optical society apply optics of the layers of this spread. Look at here of this communication of simulation engineering of this technology and some. The triple e-journals in the world. It's very important because we have all journals are q1 or q2 except for three q3. Look at that here. In blue q3 optical engineering, European Journal of Physics, Journal D, internal journal only to q4. Those are optica for the applicable and you know of nonlinear optics, physics and materials. Regarding the productivity between 2003 and 2020, we can see here 2003 35 papers and in 2020. 2002, an increment factor of 5.8 is a big increment from 2003 2002. The international collaboration in 2003 was 668.6 to 61.9 is almost the same above 60 and the output in q1 remains almost constant. 31.2 to 30.2. You can, you have to notice that this is the variation in this in this data, depending on the new professor that returned from other countries to Colombia to the research and the changes of the funding policies. And also, we can conclude the opti research in Colombia and established area area of research with active groups groups around the world with high impact in his products. Finally, finally, finally, we can see here, look at the general productivity for Colombia in all areas of knowledge. According to Simago Journal and Contra Rank, Colombia is in the place 48 of the countries. And we can see here, to the right, upload with the contribution to Colombia to the world, Latin America or Iber America. Pay pay attention on this line, the oldest line. This is the contribution to Colombia to the total production of Latin America of Latin America in 2003. The contribution of Colombia was 2.6% of all the contribution of Latin America. While in 2020, in 2020, the contribution was 8.75%. An increment factor of 3.4. This is talking about all the areas of research in Colombia. Then we can say the productivity increased from 2003 to 2020 with this increment factor and look at this. The increment factor of all areas was 3.4. While the increment factor for optics was 5.8. Well, we can say the increment of the optics area was superior, I'm sorry, I'm sorry, was superior to the increment in all areas. The performance of the optics research was superior to that, if we saw all areas. Finally, this work is done with a lot of collaborations. My colleagues from the University, we work in the, since the beginning in this world, I have, I have active collaboration with Centro Investigaciones Opticas in Argentina. And now I started a collaboration with one of my past students. Carlos Regoso Campo, a nice professor in the University of Maryland. Some institutions help me a lot, my university, the Ministry of Science of Colombia, the Ministry of Science in Argentina, and also the International Center for Theoretical Physics. And finally, the program of associates, I started as a junior associate and now I'm a regular associate, and I am also associated for us, the World Academy of Sciences. And obviously, are you, are you welcome to my university. Thank you very much for your attention, you have questions. I'm here. Thank you very much. Wonderful talk and presentation of looks like things are picking up in Colombia. And thanks for the advertisement. I think we do have a we have a question from Henry right, Abdul. Yes, Henry, Henry, you can unmute and ask a question directly from the speaker. Yeah. Yes, thank you. I didn't quite understood the, the, when you mentioned that the key is physical. So in that sense, I was wonder how the description process is sensitive to the natural degradation of the materials about the time. So, what are the plans for the, what are the, how, how are you thinking to solve this possible situation. The grid or any physical device optical device could suffer some degradation with the time so I don't know at this point, this is a matter of concern. Yeah, that's my, my question. Okay, Henry, thank you very much for the question is a very interesting question. The key for this optical system is the, the security key, of course, the security key in this case is a grown glass diffuser is a glass with different brownies around the areas. And usually these, these keys are generated for certain time, for example, you create a thing, 10 security keys and use that key for example for one month. Also, there is a very interesting topic you can generate biological for example, biological keys. This case has several advantages. For example, you generate the kids, the kids without biological matter. And you can use this case for one month. If you want to capture this key, I want to, to, to register this case that the biological system change and the kids are different. Maybe it can be a problem, but can be an advantage you can use the system that helps a key that changes to protect the information along the time. But usually, usually we use glass diffusers, they're not changing time. Thank you. Thank you very much. Just take a moment. Welcome. From seconds just to, to help you that maybe I will contact later. How to help me to start some optical group here in my university, as I say. So, later. You're welcome. Write me an email. I am happy to help you with every talk. Don't worry, don't worry. Thank you. I can help you. It's not easy, but you can do it. Well, that's great because that, that's part of the networking that I remember so fondly from when we were doing these optical colleges over the years. Here in person at ICP. Any other questions or. I don't see. Okay. Well, thanks, thanks very much John Freddie that was a really great overview and what an interesting topic. So we're going to go on to our last, last talk today. I just want to remind everybody again, because many.


The Agriculture Ministry in collaboration with the FAO Mexico Caricum Initiative, Cooperation on Climate Change Adaptation and Resilience in the Caribbean, has carried out a health assessment of students currently enrolled in the National School Feeding Program, with the goal of generating an insightful description of school meals provided in the program and students' health needs in order to assess the level of congruence between them. The nutrition consultant, attached to the project, Euphalia Filgens, explains that with global trends indicating that an increasing number of young people are developing many non-communicable diseases as a result of the food they consume. This initiative aims to ensure that the food offered to students through the program is healthy and nourishing. So we wanted to ensure that our students that whatever we are creating, the menu that we are creating is suitable and meeting the needs of our students. It's not just a menu that we just put from our head, but a menu that meets the needs of whether our students have any communicable diseases such as high blood pressure, diabetes, the menu can still meet their needs. And I think we achieved that goal. So when we went to the different schools, we took the students' blood pressure, they hide their weight, we also took their pulse and also their blood sugar level, their glucose level. Highlighting the importance of children to St Lucia's future, Chief Agri-Enterprise Development Officer of the Ministry of Agriculture Thaddeus Constantine says the food and nutrition issues faced in St Lucia require a multidisciplinary approach and measures that are a composite of policy, legislative and institutional action. We wanted to ensure that within the school feeding program, the work that we do would be able to address some of these challenges and also to ensure that the students would be provided with the best opportunities to learn. So to ensure that the menus were properly formulated, we conducted this health assessment and this health assessment now will inform what are the ingredients to be put into the menus as we go ahead with the school feeding program. This assessment should be continued, it should be repeated annually and it should be extended to also the secondary schools so that we get a good clarification of the health of our students because if a student is not fed properly, he will not be able to learn for that day. Everyday loss cannot be regained. Approximately 7,000 students are currently being served by the national school feeding program. As the agriculture ministry continues to unpack its plans for improving food and nutrition security in the coming months, the focus will remain on the students ensuring their proper nutrition through access to healthy meals. From the communications unit of the Ministry of Agriculture, I am Manisha Antoine reporting.


Hi this is Christian again this time we're going to do another in-place algorithm using strings. Now the examples we've been doing so far are just given numbers. Now if you deal with strings it's a little bit different because in Java strings are immutable that means you can't really just replace a character. So no matter what you still have to recreate a new string anyway but I'm going to show you how you can do that using just in-place algorithm. Okay so a string will work just like how we did earlier using this in-place with a temp variable like this that will be fine no problem. So for example if I go back and change all these here and let's create a new a string variable here we'll call it ststr has some origin here and I'm going to go back and collapse these so I have some more space more room and we can use things like eight at chip string and then eat okay five we enough if it pass that over to the print function let's print them out before and after and we'll be use that in-place temp just to show that it does work okay so if I can see that now going to run you should print out those words in reverse order as you can see over there okay so this time I'm going to do something similar to these two operations using just pure in-place okay so let's go back and create another function here and we collapse these so it's not too distracting let the static oops and place str we're passing a string array and then let's see how we do this so what do we do this time the idea or the approach I'm going to take is really I'm going to combine or join two strings together and put it into the first lab so will be something like this let me if I can annotate this quickly here again my tablet is not really nice I'm not really good at it so I apologize but let's say I want to you know swap this position which is the zero position with the last position of the fourth index okay so first n of one n of zero n of the zero position will be I basically joined the word eight together with the word eat right so I get the position add them up you get that string okay so now n of the last position how do I get the word you know eight out of here and put it over here okay so what you can do is you get the substring of this the position here is as you can see at the I want to I want to get this whole string substring out of it and so it is like a zero one and two I'll stop at three okay how do you know what you stop well you stop it you if you know the size of the original string eat here right you get that there and then that would be the ending the stopping position and you will go from zero up to the size of this and we stop there right so we do that you're going to get the word you know at the at the end position of n of zero I put s here for substring starting from the zero position all the way to the size of the word because it would be a three right just like that so really you have to get the whole string here the size of the entire string subtract the size of this word eat so you get in this case you're going to get three anyway but you know it's the whole string would be six minus the size of this three and you get a three so that is just the stopping point okay that's how you get this number right here okay this number of comes from this entire string and then if I go back and then go and update the end of zero you still deal with the entire string here now it's going to be the end of zero the substring of again if you do a subtraction you're going to get starting from the third position and then all the way to the end all right so create the loop so for every i zero and that's then the length of the string power two okay the first position the string of the i position is equal to the string of the i plus the string of the last one which is the position of the last so that'll be the string the length minus one minus i okay that would be the last one in this case is the word the words um eight and then eight that is in that position uh not equal sorry minus minus and then we got that in there now last we placed the last position with the word eight so that would be str of the last position is the um string that length minus one minus i equal to the string first position which is i is substring starting from zero all the way to the size of the last string right which is the word eight so it would be the string that of the string that length minus one minus i and then get the size of that okay a lot of pretty long here um no that's not right right we want to subtract from here so what of this word was if it's like eating if it's eating right you want to subtract that many okay the whole thing here subtract this many to get the correct position okay so that means i have to subtract this whole thing i mean this whole thing here from the size of this whole thing which is in of zero s of zero so here really to do one more thing string of the i that length minus that yeah i think that's it okay let's see that works and then finally the string of the i position is going to be the string of the i okay that substring of the size of this last position because at this point we already swapped and we got the word eight okay so here on we're going to ignore the eight and we'll start from eating only right so how do you start from here is the size of this you can start at the end of the size of this so in this case it'll be the substring of the string at the i position maybe the last position minus i minus one minus i and then that length and then we go all the way to the end of that and we just leave it blank like that and that will give us the word eating okay let's see if this is true let's give it a shot and here we go you can see that it's working beautifully okay eating and that's work so that is you know a lot of typing a lot of word here but um at least you see that we did not create any additional variable to store another variable so thank you


Good morning, Hank, it's Tuesday. So when I think about advances in the field of medicine, I usually think about, you know, like, medicines, antibiotics, anesthesia, chemotherapy. And if I think harder, maybe I'll consider medical devices like dialysis machines or artificial joints or refrigeration systems for vaccines, but I should be thinking about something else, too. So this is vibriocholary, the bacterium that causes cholera, a diarrheal disease that usually only lasts for a few days but can kill you very quickly via dehydration. It used to be one of the world's biggest health problems. About 160 years ago, a pandemic killed tens of millions of people, including over 150,000 Americans, one of whom was the U.S.'s 11th President, James K. Polk. Such was the fear of cholera, that Polk was initially buried not with a fancy ceremony befitting a president but in a public cemetery, as dictated by infectious disease regulations. Cholera was terrifying. You could lose 20 pounds of body weight via diarrhea in under a day, and depending on the strain, it killed up to half of the people it infected. And today, for most of the world, it's gone. Not because of antibiotics, although they can shorten the course of the disease, or because of vaccines, although there is a vaccine that provides up to six months of protection, but because of sewers and water purification systems. Cholera is caused by vibriocholary, but it's also caused by lack of access to clean water, which means that it's not just a health problem, it's also a social and political one, and we're seeing that now in Yemen. So around the world every year, more people have access to clean water and safe sanitation facilities, but even before the Yemeni Civil War that began in 2015, Yemen was one of the few countries on Earth where access to safe drinking water had actually declined since 1990. But since the war began, the situation has become truly dire. The war has displaced millions of people and killed more than 10,000, and thousands more have died from what is the worst outbreak of cholera since at least 1949, when good records started being kept. The outbreak began after the bombing of Yemen's capital, Sana'a, led to the failure of the city's sewer system, and cholera has now spread through most of the country. The World Health Organization estimates that over 500,000 people have been infected, about half of them children. Now cholera is treatable. The first line treatment is oral rehydration solution, which is super cheap. In fact, versions can be made at home with just a few ingredients, but it requires clean water, which is in short supply in some parts of Yemen. And the outbreak is complicated by the fact that most health workers in the hardest hit regions haven't been paid in over a year. Also, malnutrition is now common among Yemeni children, which lowers their resistance to infection. Despite these challenges, the cholera outbreak in Yemen has so far been less deadly than many previous outbreaks, partly due to the strains of cholera involved, but also because non-governmental organizations like Save the Children are working in extremely difficult conditions to provide oral rehydration solution. And many Yemeni health workers continue to provide care even as they go unpaid. But one of the hard truths about this epidemic is that fewer people would be dying if the world were paying more attention. I think there are a lot of reasons why we find this story difficult to pay attention to. The civil war in Yemen is complex, and there's no clear or simple path to peace. The political drama in the United States feels so astonishing and unprecedented that it's difficult to look at anything else. And also, most of us don't feel like we can do anything about cholera in Yemen, but that is simply not true. By donating to organizations working in Yemen, we can help pay for healthcare workers and the hydration solution that saves so many lives. And I'd also argue that we make a difference just by paying attention. For one thing, it encourages more news coverage about the crisis, but it also helps shrink the huge empathy gap between the rich and poor worlds. When there's a political or health crisis in Europe or Australia, I pay more attention than I do to crises elsewhere, even though Europe and Australia are distant from me because the people who live in those countries feel close to me. I watch them on YouTube. I read their posts on Reddit. I really believe that all human lives are equally valuable, but I can't live that belief if I can't empathize with the challenges faced by those who live in poverty or in fear of cholera. So I'm trying to pay attention because the cholera outbreak in Yemen is a health problem and a political problem, and also an empathy problem. Hank, I'll see you on Friday.


Welcome to my latest review of the Forbidden 2020 Manifesto. Now I'm going to be making my way through the Manifesto at a rate of about two a week. So share these, share these videos. I'll be producing a video, blog and audio of every aspect of the Manifesto. Forbidden.uk slash Manifesto. So please do share these. Today I'm going to be looking at the NHS. And as anyone who lives in the UK and preferably not under Iraq will know that the NHS is one of the primary political subjects in this country and is always at the forefront of campaigning on every single general election. Now I am supportive of the NHS. I worked in the NHS for some years. And I know there's something of a disagreement among people generally actually but particularly on our side of politics about the state provision of healthcare. A lot of people not over the moon about it. For myself I think it's very smart. I think if there's any tax I don't mind paying. It's one that will ensure I have healthcare free when I need it and that I don't have that extra burden on me which the poorest people in society had prior to the creation of the National Health Service. I think it's quite smart to pay into a public fund and have all your healthcare available when you need it. It's a good idea. And I don't really see it as, you know, I'm pro-free market of course I am but I think on this for some things we already make exceptions. For example the police are funded by the state. The social services funded by the state, ambulance services, fire services and I guess I see healthcare in the same way. I think it's, as I say, I'm happy to pay tax for my healthcare to be covered and I'm sure many people are. There's also a moral aspect to this. Do I think we should leave the poorest people to be ill and die? No I don't. So I've supported the health service all my adult life but do I support it in its current form and the trajectory and the journey it's going on? No. I think it needs major, major reform and you'll probably hear this as well coming from politicians, come election time, we must reform the NHS. Actually they haven't given any concrete ideas about how to reform it and the only thing that you generally see is a promise to throw more money at it. So as you'd expect for Britain has a rather different approach. We keep the NHS definitely and if you're worried about that for the political aspect of it, I think the majority in this country were asked, I think the majority would want to keep the NHS and as a side note I actually think that the NHS or lack of support for the NHS was one of the reasons that UKIP was never going to succeed in labour areas. That's just an opinion. Anyway, let's get on with reading the manifesto on the NHS. So for Britain supports the National Health Service and the principles on which it was built. We believe that healthcare should be available to all British citizens and those legitimately entitled. Now those legitimately entitled as you might be able to guess does not mean someone from the other side of the world who's never before visited Britain and paid opinion tax. So I'll get on to that in more detail in a second. For Britain is aware that prior to the introduction of the National Health Service the poorest in society could expect ill health, lower employment prospects and crippling worry about the prospect of illness and we will prevent an attempt at return to this society. I don't want us to be a heartless society. I think that people who are disabled or ill not only should be cared for but should be cared for better than they are today. For Britain acknowledges the vast numbers of NHS staff who work tirelessly to provide this service and we acknowledge the high standard of care delivered by the NHS and the numerous lives it saves and enhances each and every year. Now I have to say I've used the NHS several times and I have had great service. At GP I went to a couple of years back I was a little bit shocked at how busy it was and I was a little bit shocked at the doctors and the lack of personal care. It was almost like a conveyor belt. So they've become really, really busy. I went to A&E when I hoped my foot wants fantastic service. One can't complain all the time about the NHS but it's certainly the standard is certainly going down because there are too many people using it and not enough people staffing it and it has got staffing problems with nurses and doctors. However, government spending on the NHS continues to rise with Prime Minister Boris Johnson promising an extra 1.8 billion in 2019. Waste is a common area of criticism in the NHS and one report in 2017 revealed that the NHS wastes around 7.6 billion per year on quote-unquote management consultants and the procurement of overpriced goods. Now the politicians who will throw extra money at the NHS are not talking about where that money is going and there doesn't seem to be any conditions placed upon the money or any accountability for the money and we know why is the health service spending almost £8 billion a year on management consultants? Why is the management paying to consult people to tell them how to manage? That's what's happening at a cost of almost £8 billion. This is not small change. The procurement of overpriced goods would shock you. When we have examples of hospitals paying £1 or over £1 for something that's actually available for 15, 16p that's not a definite example but that's the kind of margins we're looking at in what hospitals are overpaying. There's going to be a look also at drugs themselves. So spending in the NHS both on external consultancy services and goods has got to be looked at and I don't mean talked about and let's have a meeting to talk about it and then go on and carry on as usual. Something must be done. We need to send people in there who will sort this out. The NHS also spends an estimated £2 billion. Again, we're not talking small change here on so-called health tourism and that is people coming to the UK solely to utilise the healthcare system. As I said, I worked in the NHS and this happens. This happens quite a bit and also what you'll find are people who are diagnosed with a specific illness, quite a serious illness. In my case HIV, that's the area that I worked in. People will be diagnosed, people in South America, for example, diagnosed on Tuesday and moved to the UK on Wednesday. We know what this is and it's not about being heartless. It's about reality. It's about knowing that we cannot ask the already over-bordened British taxpayer to pay for the whole world. It's simply not doable. For Britain is aware that privatisation has soared in the NHS in recent years. In 2017, one report claimed that as many as 70% of clinical contracts in England had been won by private companies with major firms like Virgin winning contracts worth £1 billion. Now, here's where the free market versus state provision argument and element comes in and I don't actually like the idea of massive private companies coming into the NHS because the fact of the matter is that the service hasn't gotten any better. In fact, in my mind, it's still deteriorating. So what we're doing is paying out money to major companies, very, very wealthy companies to provide services in the NHS costing an absolute fortune and the services are not getting any better and yet there is public money going into already very, very wealthy private pockets. I'm not 100% happy about that and I can bet that a lot of the tax-paying public are not happy about that either. In addition, serious questions have been raised about links between members of parliament and major drug companies and whether politicians may be profiting from the private sale of NHS assets. In 2014, a report revealed links and connections between politicians and healthcare giants. Unite the Union claimed that 24 MPs and peers who backed health reforms that allowed further privatisation of the NHS were linked to private healthcare companies. Now, what does that all that mean? That means that politicians who will personally profit on the sale of an NHS asset to a private company or the outsourcing of an NHS service contracted to a major company is voted on by people who will financially profit from that very transaction. I don't like that, that stinks. I don't think members of parliament should be making money out of the decisions they make about our public services. You may think differently, I doubt many of you will. Finally, it is widely believed that the NHS is too top-heavy with regard to non-medical management and admin, while nurses and doctors are underpaid and overworked. In 2018, it was reported that 33,000 nurses leave the health service every year, while nursing levels are still putting lives at risk in 2019. Now, I've made a video about this before and I will link to it below about policy on the staffing of the NHS. The Tory answer is easier immigration for NHS staff. My response to that would be why don't we try training the thousands upon thousands of young Britons every year who can't get either nurse or doctor training places in the health service? Why don't we start training them instead of opening the borders? It's wrong and crazy to be allowing mass migration to staff the NHS while British people are trying to work in it and not able to, not being given the training. If we are going to pour all this money into the health service, I suggest we put it into training instead of opening the borders. Here's the list. For Britain, we'll audit the NHS. The British public deserves to know where NHS money is being spent and who is profiting from it. Now, if auditing the NHS sounds expensive, I bet quite a few queered that we'd actually end up saving significant billions if we actually found out where the money is going and, well, shall we say prioritised it rather better. End the privatisation of the NHS and introduce reversals where possible. And I think I've, you know, even for the free market versus state provision argument, I think the answer to that I've already given. I'm not, I don't think public money should be going into private pockets to provide a service that could actually be even better provided by the state. There's no difference that we can see. Subject hospital chief executives to public scrutiny via a Public Sector Accountability Act. Now, give it that, get onto that in more detail when I cover government, which I'll do early next week. Incentivise NHS senior management to target waste and health tourism and that's pretty easy to do. All visitors and migrants entering Britain will have valid health insurance. You have to have it when you go to other countries. You have to have it here too. Ensure that only those who have lived and worked in the UK for a minimum of five years are entitled to NHS care and that's who I referred to at the beginning when I said legitimately entitled. Bar members of Parliament from profiting from NHS contracts. Just that sentence alone, I think. Most of you will agree with. Ensure that a sufficient proportion of NHS funding is directed at the provision of those suffering from mental health conditions. Now, we have a mental health crisis in this country and we can talk endlessly about the causes for it, which are important, of course. I think there are many causes for it. I think lack of empowerment in society. I think a lack of trust in leadership. I think confusion. I think lack of security in the family and economic security. I think our society has lost a lot of its community and I don't think that. I think that's pretty clear to most people. I don't think that the spirit has vanished. And also I actually think we're very stressed these days from this sudden explosion in my lifetime we've gone from having a phone in the hallway with a dial on it to being able to broadcast from our pockets to the whole world and having information on hand, a lot of false information. I think we're crowded by information and it happened very, very quickly and I think it's very stressful. Scrap parking charges. It's shocking to think, isn't it? When you think of all the money that's wasted in the NHS someone wants to visit their old gran in hospital and has to pay. Again, we're not talking about a couple of quid. This is appalling. Absolutely appalling. Penalised patients who fail to attend outpatient appointments without valid excuse. Anyone who has worked in the NHS who saw this a lot people just don't bother. And this is one of the downsides in offering something that is free at the point of use. And I understand that people will take advantage and they will abuse it. And we have highly paid consultants who should be highly paid. That's not an issue. Highly paid medical consultants whose appointments are valuable and people just take them for granted and make appointments and just don't bother turning up repeatedly. And this is a great waste of time and resource and of course a waste of an appointment for someone else who might really need it. There's got to be a penalty and it's got to be a financial penalty. And yes, I know that's taking money from someone who's probably already on benefits but look what do we do? What do you do? You've got to penalise in some way. You've got to draw people's attention to this. They cannot abuse the health service in this way and sometimes you need to take as well as a carrot. So that's it. I mean these are common sense again. I say it all the time. Before I say it all the time for a reason. Common sense policy that will sort things out will change things in the health service. At the moment the two major parties all they're promising is to throw more money at it. But when money is going down the drain they're just pouring more of your money down the drain. The NHS stays, yes but it must be run better. We can't just talk about that we have to do it or we lose the NHS altogether. Common sense for Britain has it we'll apply it to the NHS and we'll save it.


The solar cell is the fundamental component of a photovoltaic PV system. Its precise modeling and estimation of its parameters are of paramount importance for the simulation, design and control of PV system to achieve optimal performances. It is difficult to estimate the unknown parameters of solar cell due to the non-linearity and multimodality of the search space. Conventional optimization methods tend to suffer from numerous drawbacks such as a tendency to be trapped in some local optima when solving this challenging problem. This paper investigates the performance of eight state-of-the-art metaheuristic algorithms, Mars, to solve the solar cell parameter estimation problem on four case studies constituting of four different types of PV systems, RTC France solar cell, LSM 20 PV module, Solarx MSX 60 PV module and SS 2018 PV module. These four cell are modules are built using different technologies. The simulation results clearly indicate that the Kube-Bird optimization technique obtains the minimum root mean square error, RMS-E, values of 1.0264E05 and.

Since we have brothers here who are artists and they write about the Prophet Muhammad, Insha'Allah I'm going to also share my poetry that I wrote about the Prophet Muhammad. This is my experience when I went to Medina and during the quarantine I was inspired to just learn the piano and just you know learn basic stuff and I wrote this song about the Medina Insha'Allah. So I'm going to recite that for you guys and maybe do some other Nashid insha'Allah later. Alright Bismillah. This is this song it's called let's go back to Medina. I wish I could go back to Medina. Oh Medina and smell the air walking right through there on the white marble floor. Oh this place oh so pure patiently waiting to enter the door of peace. Being here my heart feels so at ease with the ummah sending our salutations to the best of all creation. I can't believe my eyes feels like paradise.
