Hello, and welcome to this presentation of the STM32 Display Serial Interface, or DSI, host. It covers the features of this interface, which is used for connecting graphical displays to the microprocessors. The DSI host, integrated inside STM32MP1 microprocessors, provides a high-speed communication interface, enabling communication with a display with a reduced pin count. This interface is fully configurable, making it easy to connect DSI displays available today on the market. Applications benefit from the easy connection and reduced pin count. The DSI host, integrated inside STM32MP1 microprocessors, offers three operating modes, and is optimized for communication with graphical displays with a reduced pin count up to 2 gigabits per second. The number of data lanes is configurable to fit exactly with the application's needs. The DSI host is deeply integrated with the LCD TFT display controller, or LTDC, to ease application development and porting. Three operating modes are available to convey the graphical data to the display. Video mode streams over the high-speed link the RGB data and the associated synchronization signals directly generated by the LTDC. The streaming starts as soon as the DSI host and the LTDC are enabled. This continuous refresh is the best way to interface with a display without graphics RAM, or GRAM. APB command mode sends commands over the high-speed link for configuration as it is done using a legacy serial interface, SPI or FMC. The commands are launched using the DSI host APB interface. Adapted command mode is the best way to interface with a display having its own internal graphics RAM. The DSI host captures only one full frame coming from the LTDC and transforms it into a series of write commands to update the display graphics RAM. This one-shot refresh automatically sets a control bit in the DSI host. The DSI host's video mode supports the three operating modes defined by the Mobile Industry Processor Interface or MIPI DSI specification. Non-burst with sync pulse, where the synchronization signal and the data are sent accurately, enabling the target display to reconstruct the original video timings, including synchronization pulse widths without any buffering. Non-burst with sync event mode is similar to the previous mode, but for displays not requiring synchronization pulse width information. Burst mode is the most energy efficient mode. RGB pixel packets are time compressed, leaving time during a line transmission to go into low power mode or to transmit other commands. The DSI host must support all three modes. A display is only required to support at least one of these three modes. APB command mode is used to send commands through the DSI host APB register interface. Generic or display command set or DCS commands can be sent for display configuration at startup or for maintenance operations when the application is running. All the commands can be sent either in high speed mode or in low power modes, as some displays only accept low power communication at startup. Commands can also be sent during video streaming. The DSI host scheduler automatically evaluates if it has the sufficient time to insert a command during a video transmission, according to the program timings. All the commands are fully programmable by software, which means the DSI host supports all the standard DCS commands and all the display-specific custom commands. Adapted command mode is a highly optimized operating mode to interface with displays having their own graphics RAM. It automatically refreshes the display's graphic RAMs or G-RAM with the LTDC without any load on the CPU or DMA controller. The graphics RAM refresh operation works in conjunction with the LTDC. The DSI host controls the LTDC and enables it for one frame. The RGB data coming from the LTDC are captured and are sent into a series of DSA long write command packets to the display. Once the graphics RAM is completely refreshed, the DSI host automatically stops the LTDC and the DSI link goes into low power stop mode. The user controls the refresh operation of the display by just setting one bit when the frame buffer is ready to be sent. The display can be refreshed at the maximum speed of the link, so special attention must be given to the bandwidth requirement on the LTDC side. In other words, memory bandwidth to read the frame buffer. The tearing effect allows a perfect synchronization between the display and the DSI host for refresh operations on displays having their own graphics RAM. The tearing effect can be signaled in two ways. Over the link without an additional pin or using an additional pin. When the tearing effect is signaled over the link, the DSI host sends a set tear on command and gives the control of the bus to the display. Once the program scan line is reached by the display, it sends a trigger to the DSI host and gives control of the bus back to the DSI host. An interrupt can be raised to launch the graphics RAM refresh. When the tearing effect is signaled over a pin, the display toggles a dedicated GPIO to trigger the DSI host when the program scan line is reached. Although an additional pin is required, this mechanism avoids having multiple exchanges over the link between the DSI host and the display. An interrupt can be raised on the pin, toggling the launch of the graphics RAM refresh. The choice between video or adapted command mode has a big impact on the solution's architecture and cost. From the MCU standpoint, adapted command mode is preferred for cost-optimized solutions. As video mode does not require graphics RAM on the display side, this solution is often used for large displays which reduces cost. The constraints in terms of bandwidth and memory usage on the MCU side remains the same as for today's LTDC-based solutions. Most of the time, an external RAM is required for double buffering of the frame buffer. Adapted command mode requires a display with a graphics RAM. The display may have a slightly higher cost, but most of the displays smaller than 480 by 480 pixels embed a graphics RAM. As a consequence, adapted command mode with a small display will not always require an external RAM as the frame buffer may fit in the internal MCU RAM. This highly reduces the bandwidth issues on the MCU and reduces the overall bomb cost and solution integration as no external RAM is required. The DSI host supports video mode operation with timing accurate streaming, burst mode to reduce consumption during blanking periods, and several RGB color encoding formats to optimize bandwidth usage. The DSI host supports commands through its APB interface. DCS or generic commands can be issued to the display even when video mode is working and commands are used for display configuration at startup and also for maintenance operations when the application is running. The DSI host can also use adapted command mode to update a display's graphics RAM without having to use the CPU or DMA controller. This mode works using the LTDC to transmit write commands to the display. In terms of performance, there is a relationship between the equivalent pixel clock and the DSI host configuration. Depending on the color coding, the number of data lanes used and the speed of the data lanes, we can evaluate the equivalent pixel clock. As an example, a 720p 60 display with a 16-bit per pixel coding is supported with a single 900 MHz data lane and a 1080p 30 HD display with 24 bits per pixel coding is fully supported with both data lanes at 1 GB per second each. The DSI host has many interrupts to monitor all timings and events of the communication. Please refer to the reference manual for a detailed description of all the interrupt sources. In addition to protocol-related interrupts, the DSI host also provides interrupts to manage regulator events, PLL events, and tearing effect events. As the DSI host uses the LTDC for data fetching, no DMA controller is necessary. The LTDC has its own DMA master. The DSI host peripheral is controlled by the Cortex A7 core only and so is linked to its power modes. The DSI host peripheral is active in C-run and C-sleep modes. A DSI host interrupt can cause the device to exit C-sleep mode. In stop modes, the DSI host is not functional and its register content is kept. In standby mode, the DSI host is powered down and it must be re-initialized afterwards. Wearable applications require low power management functions together with a high quality user interface. This can be achieved using the DSI host to interface with a display through only four or six pins. The low pin count needed to drive such devices allows for a highly optimized system integration. You can refer to the training slides related to RCC, interrupts, LTDC and GPIOs for additional information.

Hello, my name is Peter Briggs and I'm a software developer and Galaxy administrator in the bioinformatics core facility at the University of Manchester in the UK. Today I'd like to talk to you about some recent updates to our Nebulizer utility. Nebulizer is an interactive command line utility for remote Galaxy administration. It helps with basic everyday admin operations, including query management of users, tools, quotas and data libraries. It was first developed in 2015 to help manage multiple local galaxies that we were running from the core facility, and it complements the Galaxy Web admin interface. Among its features, it's a Python package, it uses Python 3.6 or greater, and it's built on top of BioBlend, which it uses to access the Galaxy API. It's available from both the Python package index and also from Bioconda. It's interactive and it has a simple mechanism that allows you to associate aliases for different Galaxy instances so it's easy to work with multiple servers. Its text output can be used directly with other command line tools such as grep, and it works with any Galaxy version that is supported by BioBlend. Nebulizer is one of a number of BioBlend-based utilities for managing Galaxy instances. Others include Ephemeris, which provides utilities and scripts for bootstrapping and provisioning Galaxy instances, and Parsec, which is a tool kit for pipelining together low-level BioBlend functions into custom scripts. Nebulizer has some overlap with both of these packages, but it differs in that it provides a simple interactive high-level set of commands that are primarily aimed more for day-to-day admin and maintenance of Galaxy instances. I'd now like to show some examples of Nebulizer in use. For example, you can find out if a Galaxy instance is alive by using Nebulizer's ping command to see if a server returns a response. You can find out what version of Galaxy is running on a particular instance by using Nebulizer's config command and then grappling out the version information. You can find out which users on a particular instance are using the most disk space by using Nebulizer's list users command and then sorting on the disk usage. You can install tools, for example, multi-QC from the toolshed quite easily by using the install tool command and then target a particular tool panel section to put that tool into. You can find out which tools on a particular instance have updates available in the toolshed by using the updatable option of the list tools command. And you can easily update one or more tools from the toolshed using the update tool command, which will pull in the latest versions of any that need updates. The most recent release of Nebulizer includes several significant updates. For example, there are new quota management commands. There has been a substantial simplification and refactoring of the tool management commands to improve ease of use. Please note that if you have used Nebulizer in the past and this is a breaking change, the update tool command can now use wildcards so you can specify multiple tools to be updated in a single invocation. And the list users command now allows filtering on things like user status and you can also sort on disk or quota usage. Finally, we've also dropped support for Python 2.7. Looking to the future, I have a wish list of functions that I would like to implement, including management of groups, extension of the existing user management functionality to allow things like password reset. It would be great to be able to do this running jobs and I'd also like to improve the test framework. However, this is very dependent on time as I'm the sole developer on this project at the moment. If you wish to try Nebulizer for yourself, then you can install it directly from the Python package index or from Bioconda. There is extensive documentation available at Read the Docs, which includes an in-depth tutorial. There's also source code available on GitHub. Finally, I have a poster and a software demo, so if you wish to learn more, then please come and see me later in the conference. And thanks for listening. Hope you enjoy the rest of GCC 2021.


After the event, she said, she gave me a big hug. I said, thank you so much, David.  You have no idea how much this means to me. I would have never thought it would be back out meeting people, talking to people, and doing business again. So that was just very heartwarming. She also uses it with her one-year-old child. And she's been using it for two years now. He's three years old. And now he sleeps easily whenever the coil is on. So we figured that out. We figured out the sleep thing with the kids. And also, interestingly, he can communicate much more articulately with much more articulation than all the other kids his age.


If a complex number z equals a plus bi, the complex conjugate, written as bar z, is a minus bi. The same terms just the imaginary part is subtracted instead of added. For example, let's find the conjugate of 8 plus 2i. The conjugate will have the same terms, but instead of adding, we'll subtract them. Now, in pre-calculus and lower-level courses, the conjugate is often introduced because the product of a complex number and its conjugate is real. This is true, but it's not that big a deal because it's also true for non-conjugates as well. For example, let's find a non-zero complex number a plus bi, where the product a plus bi times 8 plus 2i is real, but a plus bi is not the conjugate of 8 plus 2i. So, let's set that up. We want to consider the product, and let's go ahead and expand it, and collect our real and imaginary terms. Now, in order for the product to be real, it's sufficient that the imaginary part be equal to zero. And notice that there's an infinite number of possible solutions to this equation. For example, a equals 4, b equals negative 1, and that gives us a factor 4 minus i, where if we multiply it by 8 plus 2i, we get a real number. So, what's the big deal about the conjugate? Well, there's actually two key properties of the conjugate. The conjugate of a complex number z is a unique non-zero complex number that satisfies z plus its conjugate is a real number, and z times its conjugate is a real number. We can prove this, but you should do this. So, here's a hint. A general strategy to prove that something is unique is to assume that there's another one. So, if our complex number is a plus bi, the conjugate will be a minus bi, and suppose we have another complex number, a prime plus b prime i, that also satisfies the property that the product and sum are real numbers. What does that tell you about a prime and b prime? Now, in addition, the conjugate satisfies a number of other properties, let u and v be complex numbers, then the conjugate of a sum is the sum of the conjugates, the conjugate of a product is the product of the conjugates, the conjugate of the conjugate is the original number, and the conjugate of a power is the same as the power of a conjugate, at least for whole numbers n. That restriction is there so that this is something that we can prove at this point. Although I can't even begin to imagine how you'd prove something like that. Induction. Did you hear something? Well, please prove one of them. So, let's prove that the conjugate of a sum is the sum of the conjugates. So, remember, definitions are the whole of mathematics. All else is commentary. So, suppose we have two complex numbers. This statement is talking about their conjugates. So, let's start with the conjugate of their sum. And, since we know what the two complex numbers are, we can do the complex arithmetic to find an expression for the conjugate of the sum. Now, it's useful to think about a proof as building a bridge from one point to another, and sometimes it's convenient to work from the end. The important thing is that if you are starting at the end, you can't go past the end. You have to go backwards. So, we want to end with the sum of the conjugates of u and v. Definitions are the whole of mathematics. All else is commentary. We can always go backwards on a definition. So, we know what the conjugate of u and v are, and let's see if we can bridge the gap between our two lines. And we see that it is only a matter of rearranging our terms, and so that joins beginning to end, and we have our proof.


friends today we are going to discuss one of the important topics of political science that is sovereignty as we all know that there are four essential elements of state and these are population territory government and sovereignty and among them sovereignty is the most important element of the state which makes the state politically free and independent both internally as well as externally sovereignty exclusively belongs to the state. So dear learner, I am going to share with you some of the important elements of the government. I am going to share with you some of the important elements of the government. So I am going to share with you some of the important elements of the government which make the state politically free and independent both internally and externally. Before we proceed further, first we should know the meaning of sovereignty. So here is the first thing I am going to share with you. Sobrenty is the most essential element of the state as there can be no state without it. The word sobrenty is derived from the Latin word superenas which means supreme. The word sobrenty is absolute, supreme, unlimited, inalienable, indivisible and permanent power of a state. The word sobrenty is the supreme power over citizens and citizens. Various scholars have defined the concept of sobrenty in various ways, among them summer as follows. The word sobrenty is the supreme power over citizens and subjects unrestrained by laws. The word sobrenty is the supreme power over citizens and subjects unrestrained by laws. According to W.F. Willoughby, sobrenty is the supreme will of the state. The word sobrenty is the absolute, unlimited power over the individual subjects and all associations of subjects. The word sobrenty is the supreme power over citizens and subjects unrestrained by laws. Regarding sobrenty, Jonathan's theory is another important opinion who said that if a determinate human superior, not in the habit of obedience to a like superior, receives habitual obedience from the bulk of a given society, the determinate human superior is sobren in that society and that society including the superior is a society political and independent. Sobrenty was defined in various ways by various scholars. From these definitions, we may find the following features. Sobrenty is regarded as absolute, which means that the state is superior inside the country. It is not subordinate to any individual or association within or outside the state. The state exercises supreme power but inside and outside the state. If there is a date of a king or the ruler, then it does not mean that the power or the concept of sobrenty or sobren power is permanent. Or the concept of sobrenty or sobren power abolishes because it is permanent. Or may the changing of the ruling authority may not be the changing situation of the sobrenty. It is ever been that without sobrenty, the state cannot exist. Sobrenty is a universal phenomenon which extends to all individuals, groups, areas and things within the state. As we all know that sobrenty covers all aspects within the states which may include the organizations, associations, individuals and others. The state exercises supreme power over its entire territory. No one can claim exception from it as a matter of right. It means that the state cannot par with its sobrenty or it cannot transfer its sobrenty to any other state. If sobrenty is separated or alienated from the state, then there will be no state. So the sobrenty is separated from the state, then there will be no state. This is the indivisibility of the abhijyota. The sobrenty means it destroys. Because if someone tries to divide sobrenty from a particular state, then it will destroy the very meaning of sobrenty. This is the indivisibility of abhijyota. This implies that sobrenty can neither be destroyed nor lost if it has not been exercised for a long period. Sobrenty may not have exercised sobrenty for some time due to control by foreign rulers, foreign power, but non-existence or non-exercise of sobren power does not put an end to sobrenty itself. It is shifted to a new era. Sobrenty can neither be destroyed nor lost if it has not been exercised for a long time due to control by foreign rulers, foreign power, but non-existence or non-existence of sobrenty does not put an end to sobrenty itself. Sobrenty can neither be destroyed nor lost if it has not been exercised for a long time due to control by foreign rulers, foreign power, but non-existence of sobrenty does not put an end to sobrenty itself. Sobrenty is the most important characteristic of sobrenty. Sobrenty is the most important characteristic of sobrenty. So, it is spontaneous. Sobrenty is in-will and grows automatically from within. So, dear learners, we have known that these are the features, important features of sobrenty which makes this concept of sobrenty very clear so that what sobrenty means in the state is all these elements. Without these elements, a state cannot be turned as a sobrenty state. In other words, sobrenty is the main important element of a state. So, thank you. Thank you all.


Hey everyone, Drew with GeoArm and I am back and I'm going to talk to you about temporarily disabling a sensor in the Geo Alarm panel. Very easy to do. Go ahead and hit the hamburger icon in the top into your passcode minus 1, 2, 3, 4.  Find the device that you're looking to temporarily disable minus here, it's the front door. So what I'll do, there's a button up here that says active, it's just a toggle. Just go ahead and hit that, it'll ask you if you're sure you want to disable it, I do want to disable it. Alright, once you've done that, if you want to re-enable it, you just press that button it'll re-enable it, I'm going to leave it disabled here and then I'm going to go ahead and back out of programming.

The pride and vanity of this world with our social media and our ability to get instant feedback on everything We say and do and everyone is now with you know, their smartphones And have constant communication with people. I think it feeds Yeah, that vanity and so a campus is a great role model for humility and he was really Recognized that he found his greatest peace and joy in this life in silence and in solitude I think this is a powerful lesson which we could learn from a lot today because as you say we're assailed by by constant Information by distractions by streams of entertainment and to step back from this You know to think while I'm going to take take a day or even to take a morning or an afternoon of quietness and solitude


presenting a patient. We have a third presentation, Charles Calvo. He's a fourth-year medical student from the University of Nevada, Reno, what we'll be presenting. And finally, if there's any time for Candon, he can present diagnostic confusion. If not, we have a whole year next year that he can present diagnostic confusion. So today I'm going to be discussing cornioscar etiology management with a patient who's actually upstairs in the triage area right now.  There's no pain associated with it. His history is only significant for cataract surgery 10 years ago in both eyes. Doesn't take any medications currently. On physical exam, initially two weeks ago, here his visual acuity was 2200 in the right eye, 2025 in the left eye. Interarchal pressure was 16, his pupils were normal. There was no fluorescence, staining scene, and he had a normal fundus. Pictures were taken when he was seen initially here two weeks ago. And as you can see here, there's some corneal haze with scar in the epithelium and anterior stroma. There's also, you can kind of see, it's a little difficult, but there's some neovascularization in the cornea. So working differential was started. He was actually referred here from St. George by an ophthalmologist down there for treatment for suspected conjugal intrepithelial neoplasia. That was part of the differential along with chemical burn and limbal stem cell deficiency. Right here on the left, we have a picture I found on the internet of characteristic CIN with corneal involvement, and then our patients in the middle here, and then I found a paper that had discussed treatment of limbal stem cell deficiency secondary to mustard gas exposure in the Iran-Iraq war. And so this patient had a partial limbal stem cell deficiency with corneal scar. Impression cytology was done on this patient because there was questions as to whether he really had CIN. And there was an H&E stain done and he was looked at under a light microscopy. And as you can see here, there's fairly normal epithelium, I mean squamous, non-charitonized in appearance with normal nucleosocytoplasm ratio. There's no mitotic figures and no chromatin clumping. The official final diagnosis on this impression cytology was corneal impression cytology showing no signs of dysplasia. So with that in mind, I want to discuss these three differentials in their pathophysiology diagnosis and management. So chemical burns, you want to look for a history of exposure. After he had been worked up, the patient mentioned that he spent his life as a cattle rancher and he'd been exposed to lots of chemicals, although he's been retired for a long time and he hasn't had any, he didn't think he got anything in his eyes recently. Limbal stem cell deficiency can actually be secondary to chemical burns. Essentially you have defect in the limbal stem cells and so there's difficulty repopulating normal corneal epithelium. And characteristically you'll get inflammation and you'll get conjugal cells growing into the epithelium. CIN is dysplasia with abnormal maturation of a corneal conjugal epithelium and generally patients have a history of excessive UV exposure, smoking, HIV also. So how do you diagnose chemical burns? You need to know if there's a history or not. Limbal stem cell deficiency, a lot of times the diagnosis can be made clinically. Through the past medical history, do they have some kind of autoimmune disease like Stephen Johnson syndrome or aniridia? And if there's a diagnosis in question, you can go to a histological exam with the impression cytology. And generally you'll see conductival goblet cells in the cornea, which was not present on our patient's impression cytology. CIN initially you can use rose bangle staining, which you can see punctate lesions. And histopathology can also be done with impression cytology. And you normally see dysplasia, unusual thickened epithelial cells. If you do see it, you can grade it with a biopsy. And CIN1 is dysplasia located in the lower third of the conjugal epithelial thickness. CIN2 is in the middle third of the conjugal epithelial thickness. And the CIN3 is in the upper third of the conjugal epithelial thickness. Crossenome of CITU is a full thickness lesion and then invasive squamous cell and it's the basement membrane. So what's the management? Chemical burn management. You want to promptly irrigate the wound. Also too, if there's history of an alkaline agent exposure, you want to monitor intraocular pressure because alkaline agents can cause an inflammatory action and precipitate acute glaucoma. Surgically, I found some research that suggested that amniotic membrane transplantation can decrease inflammation and promote epithelial healing. And like I mentioned earlier, you can also get limbo stem cell deficiency. And so limbo stem cell transplant has also been used to help promote healing of the cornea. And this patient right here was from a study that took actually, this patient actually had limbo stem cell transplant and an amniotic membrane transplant. He had a burn, sulfuric acid burn and this picture was taken a month and a half after his surgery and shows a stable ocular surface. Medical management of limbo stem cell deficiency can be double scleral lenses. I found a study where a patient had a limbo stem cell deficiency secondary to contact lens wear and they use scleral lenses for nine months in his cornea epithelial eyes and he had no pain or discomfort after that. Also conservative management with artificial tears and topical steroids. For more severe disease like in autoimmune cases where you have bilateral limbo stem cell deficiencies, you can use a credo-limbo allograft from a donor. And also you can, if the patient just has a unilateral defect from something like an alkyber and you can do a conjunctival, conjunctival limbo autograph from the patient's good eye. And then CIN management, I found a few papers that discussed the anti-cancer agents, mydomycin C5 flora uracil and interferon alpha 2b. And this patient up here actually was treated for several months with interferon alpha 2b for CIN in the cornea. And after about 18 months of treatment, you can see on the right side that the patient's wound is completely healed and the patient did not have any recurrence during the study's time, which was about three years. Surgically, neoplasm confined to the cornea can simply be peeled off the basement membrane as long as it's confined to the epithelium. Whereas, if there is neoplasm in the conging tiva, surgical resection can be done with cryotherapy. And I found a study that used that and it prevented the recurrence after about three years of follow up of CIN in the conging tiva. So our patient, he was sent home two weeks ago with really conservative management, erythromycin ointment artificial tears, steroids four times a day. And so as I finish this, I'd like to open it up to everyone who's seen the patient to discuss management options or ideas on the differential of this patient. He just started noticing it two months ago. He's had some vision problems, muscle weakness. And so he had prisms. And he started knowing that noticing that his double vision was getting better. And so he realized that his right eye was just blurry. He has his follow up care today. And I think I Dr. and body was discussing doing a graph from his other eye.


Hi, I'm Jen Henderson, Platform Support Team Manager, and I'm thrilled to be presenting this award to Erika. Erika is a force in the PSP team. She is constantly coming up with new ways of communicating policies to authors and educating them on what they can do with their preprints. Recently, she took a simple project of updating some macros for the PSP team and changed it into a whole new process on how we communicate with authors that are requesting their preprints be removed. She put thought into every way that customers were being addressed, and she even tested some of the language that she was creating while she was handling her daily tickets. This change has resulted in less preprints being removed from the platform and more authors understanding the value of preprints.


Good afternoon everyone and it is a great pleasure and honor to be here and I have to thank the organizers for inviting me To speak at this really distinguished meeting which we all enjoy and it's very interactive and I loved All of the presentation so far and I'm looking forward to many more anyway so the topic that I've been commissioned with is regarding how we achieve area under the curve that is satisfactory and we maintain this fine balance between Keeping the dose fairly reasonable as well as Managing to maintain optimal efficacy with balancing the toxicities in between so the Official definition of area under the curve is the integral of the plasma concentration of the agent versus an interval of definite time so here is the definition but bottom line what it means to all of us as When we are clinically facing a patient is that it allows us the measurement of the bioavailability of an agent that you're using And allows us to balance it with the efficacy and eventually toxicity So I have here in my estimate what the factors are that impact area under the curve compliance is a huge one the dose of course schedule Absorption and there are different ways of You know that there are different things that can interfere food and other drugs and Multiple other things that we've seen that have interacted with each of these agents and then of course the pharmacogenetics Pharmacokinetics of the agent can affect and have a significant amount of impact on the efficacy and the toxicity is noted and Toxasities of course which will have a huge impact on your area under the curve because if you have a significant toxicity that makes you Completely either discontinue the agent or hold it temporarily for quite a while That is again going to have an impact on your AUC so the impact of compliance which is not Frequently discussed but is huge and one of the report shows this is the actual Population data survey of the impact of compliance on medications treatment prescribed to treatment filled There is an actual prescription drop-off right there and then Eventually if you're looking at the treatment continued, which as you can see in kidney cancer We are not doing sporadic treatments anymore We are more vested in the continuous part of the treatment and treatment continued at least is seen in this 47% range so about half of the patients will be compliant with the medication now This is generally across different medications The good news is that compliance is fairly much much better in cancer patients So studies that have been specifically done in cancer patients show us That compliance with oral agents is actually very good So and these are very small very limited studies but this was a study of synitinib where patients 36 patients were surveyed and watched very carefully for their compliance and Only two patients were non-compliant and the reason for the non-compliance of course was Toxicity that they had grade three or four toxicities of some shape or form Interestingly though the other 13 patients who had these kind of severe Toxicity's or adverse events related to synitinib actually continued on the same dose So it's not absolute given and what we find is that patients who are being treated for their cancer with therapy actually stay Remarkably compliant despite in the face of significant Toxicity's so the other things of course are the who who what where when of medications in kidney cancer and One of the studies has been looking at exposure and dose response what we do know about synitinib is that the increase the increasing dose can result in better exposure and There are studies that show us improvement in efficacy with increasing dose Obviously the toxicities also go high up and it's not a direct relationship as you can see there are some people who at 50 milligrams are or even less doses have equal values of PKs or AUC as Somebody with a much higher dose of 75 milligrams of synitinib So here is the study that showed you that the time to progression as well as overall survival Was improved with increasing doses and this was a study again of synitinib done in both kidney cancer as well as GI stromal tumors basically showing you that the higher the dose the better the efficacy to a certain extent Interestingly though clinical studies are showing us that that didn't quite result in actual improvement in efficacy And as you're probably familiar with the Mozart study which compared patients with 50 milligram for four weeks on two weeks off schedule with the 37.5 milligrams Continuous schedule and if you look at the median progression free survival or overall survival for that matter It actually was no different with and maybe slightly inferior with the continuous dosing as Compared to the four weeks on two weeks off schedule Interestingly if you just look at dose intensity, it's actually somewhat higher with the 37.5 milligrams daily compared to the 50 milligram over Six weeks because if you calculate it out per daily dose it ends up being about 33 point three three so Interestingly it may not be the dose intensity But there might be a threshold that you have to hit to actually get to that efficacy end point is one of the Thinking behind why these studies are not showing you a major difference in efficacy and these the other two studies I have listed there are phase two trials that again looked at the continuous dosing and Came up with similar results that no different and definitely not better than the 50 milligram four weeks on two weeks off dose Again some more clinical data that tells us that dose escalation didn't quite get us where we wanted to be in Terms of improvement in efficacy is that sit in a dose titration study And this was a study of starting off with five milligram twice daily 213 patients were treated anybody with progression severe Toxicity's of course was taken off the study and then after that the patients who were tolerating it Okay, we're randomized to either get a skill dose escalated up to 10 milligrams twice daily versus placebo and the response rates and progression free survival as you can see here was no different and Definitely no better with the dose escalation as compared to placebo So again, there might be that threshold effect that you see have to see in terms of efficacy and then beyond that the incremental Advantage tends to be fairly small with a major increase in toxicity There are some patient populations that were found to be susceptible to Increased toxicity rates and for instance the there were PK studies that were done with synitin if that showed about 8% of the patients had had a dose PK levels that were at the same level at 50 milligrams that were seen at for instance 75 milligram doses so so there is that variation Obviously and female gender and low body weight people with a lot of weight loss tend to be the more likely people who have this kind of significant dose level increases and You know right now we don't have any good predictive markers to say upfront Who is likely to get increased risk of toxicity? So going back to the PK PD profile of targeted therapy, you know, I think it's pretty similar for any therapy Obviously in this kind of treatment because you have vested for patients who are benefiting in the longer term of therapy you're looking at the metabolism of the drug and The chances of absorption and eventual bioavailability to maintain the efficacy Effect and pharmacogenomics really there are some snips that have been reported usually in the metabolism enzymes the cytochrome P450 system That have been associated with increased risk of toxicity with synitinibis apanib and some for mTOR inhibitors as well That have been reported again. No exact correlation has been noted as yet So there are more studies should would have to be ongoing in this regard Same thing for genome-wide association studies have identified different loci that result in differences in the Accumulation rate of metabolites and the range is really very fairly wide from 10 to 60 percent Which obviously could have an impact on the toxicity rates And there is always that 8 to 10 percent of the patients that we when we start treatment Completely unpredictably have a significant amount of toxicity it within the first few weeks of therapy even So my conclusions of all of this come up with that pharmacogenetics at present There are none no real test that we can recommend that are ready for prime time in Predicting this incidence of severe toxicities in these patients the additionally the dose schedule and dose intensity and Probably hitting that threshold dose for the patient does make a difference in terms of efficacy But clinically when you look at populations or groups in randomized setting the dose escalation beyond the standard dose has not been proven to be of any improvement in efficacy and Currently we are stuck back with our optimizing targeted therapies based on our clinical factors such as response and Toxicities and that still remains the current standard. Thank you for your attention


Today, we will deal with basic introduction to the production and operations management. The session is mainly aimed at making you understand the concept and objectives of the production and operations management. The total content will be divided into introduction, definition, the concepts of the production and operation management, what are the objectives of it. We will start with the introduction, what is production? Production is a creation of utility. The production function creates utility by providing form, time and place utilities for the produced goods. Manufacturing provides form utility while physical distribution provides the time and place utility. Let us take a simple example. Any material in any form has definitely no doubt some utility, some value. If I change that features of the particular material item or a service into another better option then probably I have done some process on it and that process may be either a service operation or a production operation. Today has defined production as a step by step conversion of one form of material into another form of material so as to create or enhance the utility. Already the product, the material has some sort of utility. We want to enhance the utility or we want to create the utility with a particular transformation process. For example, iron ore is there. When I convert iron ore into pig iron, I am making a conversion process, it is a production process converting the iron ore into pig iron. Now pig iron has utility. When I produce casting from pig iron, I am making another manufacturing process called as foundry process where I am trying to convert the pig iron into various castings. Casting has utility. Now when I take casting, I make it machining. Then machining adds again another value that have further improvement in the value. Machine components if I assemble, assembly is an operation. It is not a production process, it is a operational process where it again adds to the value and then it has further enhancement of it. So when I transport from one place to another place, it has a place utility. Now I am moving into a service provision where I have provided some service function to the particular product or the process and as a result of that, it enhances the production. So therefore, production or operation is a basically value addition process by conversion. The conversion may be in terms of physical conversion, may be chemical conversion, may be a yearly service confirmation like moving it from one place to another place or keeping it under some controlled conditions. These are some of the service functions as such. Any manufacturing or service or production process definitely will add to the value of the particular product. Then the production management is a process of planning, organizing, directing, controlling the activities of the production function. Once we understand the production function and we understand what is management, management is basically planning, organizing, directing and controlling the activity so as to achieve the desired result. It is the art of getting the things done. So when I apply management definition to the production, then we call it as a production management process. There are number of definitions available in the variety of textbooks. So basically it is the application of the management principles to the production activity or service activity. When I apply the concepts to a service operation, then instead of calling it as production management, I call it as a operations management. So nowadays you will find that production and operation management are merged together and combined. We generally call it as a operation management as the total picture of the entire operations activity. It may include some of the manufacturing activity and some of the service activities as such. It is also dealing with decision making related to production processes so that the resulting goods or services are produced according to the specifications in the amount by the scheduled demand and at minimum cost. It is in short dealing with the production process so as to get the desired output in terms of quality, quantity and time and cost. It also can be defined as a process which combines the transformations of various resources into production or operation subsystems of the organization into value added product or service in a controlled manner as per the policies of the organization, the definition which you have just now discussed. A set of various activities which are involved in manufacturing, certain products is named as production management. We are looking into the various definitions of the production management. If the same concept is extended to the service sector, then the various management activities are called as operation management instead of a production management. In the pictorial form, the transformation process is there is a input and there is output and there are various processes which converts input into output. The various conversion processes are either production processes or the service processes. Now just think for a moment what can be the various forms of the transformation processes. You can have manufacturing processes, you can have the service processes where here is the answer. The various transformation processes can be, it can be a physical manufacturing activity, it can be a locational just like transportation from one place to another, it can be exchange in the real operations, it can be physiological as healthcare, it can be psychological as an entertainment and it can be informational as in the communication. So there are tremendous amount of transformation processes which are possible which convert input into output. The various modes and methods of transformation are the details of the various operations which we are going to study in the further part of the content. As already we are looking into it, the objective of the production management. What is the objective of the production management? It is to produce goods or services of right quality, quantity at the pre-determined time and pre-established cost. In short, the objective of the production management can be right quality, right quantity at right time. Right time is pre-determined time and at the right cost. So we can define it in another way that four hours, the first is right quality, the second is right quantity, the third is right time and the fourth is right cost. What is right quality and right quantity? Quality and quantity are as described by the customers and specifications are generally given by the customers in terms of quality. Quantity is their amount in what particular batch quantity they wanted. What is the time? The delivery schedule of the customer and the cost is of course a pre-determined cost which is generally arrived at by lateral discussions between supplier and the manufacturer or service provider. The details of the what is right quality is given over here. What is right quantity? The right quantity is, it should produce the products at the right number in terms of required this and then excess of the demand in the capital will block up in the form and it is produced in the quantity short of the demand, these will have shortages. So excess will have its own negative impact on the inventory and shortage will have its own negative impact on the customer satisfaction. So excess is also not permitted and shortage is also not permitted. The balance between excess and shortage is the right quantity in short. Right manufacturing cost so that it should be minimum possible cost as decided by the organization therefore we can be comfortable with the applicable profits. Manufacturing schedule, the delivery schedule as decided by customer and supplier. So in short when we look at the various types of production systems we are mainly aiming at what is right quality, what is right quantity, what is right time and what is right cost. We have seen that now there are very less flexibilities in terms of supply of the production or services when it comes to the actual business operations. The fact remains is that you cannot have scope for the quality deviations. You cannot have scope for quantity deviations. The cost is already determined by the bilateral agreement. The only option which we are having is the delivery schedules. I have seen number of companies which are having their competitive age. It is only in terms of delivery of the right time. Even we have come across number of cases where probably the customer is ready to pay an upfront incentive if you give the delivery on time. So in the competitive era quality cost and delivery are the major important. Of course quality, quantity and cost are the three important parameters which are generally almost rigid. We do not have lot of scope to vary for this. The only advantage we can have in the competitive market is the delivery schedules. So we must have the production planning facility, we must have the entire schedules so that we definitely will meet with the customer demand as per their time requirements. So the best competitive advantage for any manufacturing or service provision company is to provide goods and services on time. Of course quality, quantity and cost remains as a pre-requirement for the business operations.


Hey everybody, this is Brian and welcome to the 70 second Qt tutorial with C++ and GUI programming This is going to be another user feedback. I get to ask the question, Brian How do you compile and use a third-party DLL? So we're going to do this and maybe Split it into two parts depending on how big this gets. This is a fairly advanced topic So well, we'll see. All right first thing you need to do is go to the Qt website and go to downloads And you're going to want to download The Qt creator source That's right the actual source code for Qt creator this IDE that we've been working with all this time And the reason why you're going to do that is because it uses a library called botan or botan I think it's called botan. Anyways very very powerful library and what this library does is it allows for Another user feedback, which I wanted to cover encryption Brian. How do you encrypt a file? Well, we're going to cover that too So rather than have you go out and look for these arcane libraries We're going to use something that you already have the source code and the project file and everything set up matter of fact After you've downloaded these and let's say you've downloaded the Qt creator source code You can just go into the source slash lib slash third-party slash botan and open botan dot pro And you have the actual source code for botan set up and ready to go All you have to do is compile it Now after you've compiled it you are going to have a few libraries and You notice how it's, you know, Libs third-party botan build desktop lib slash Qt creator You're gonna have botan DLL bot and D dot DLL bot and a bot and a what are these? well These a files right here are just basically files that the linker can attach to So that it knows you have this specific DLL you want to bind to and the DLL on files are dynamic link libraries That's how you distribute code so someone else can use it Now botan comes with DLLs, but they're compiled with Microsoft Visual Studio And if you remember from any of our previous videos anything you compile in Qt creator uses the main W compiler So you have to recompile this library for these tutorials to work Otherwise you're going to get all sorts of unresolved reference errors So go ahead download the source Open up botan dot pro and just hit build once you're done You'll be able to find these DLLs under Third-party and then whatever your build directory was mine is botan build desktop source slash lib slash Qt creator and then actually go out and download the botan source and Then you should actually Hmm I'm not used to IE 8 here. I'm going to actually walk you through installing the botan Botan DLLs you just hit next you're gonna want to put these somewhere where you're going to be able to find them Because you're gonna have to link to these So I just do C drive button. You can put them wherever you want Make sure you include the import library include files and development documentation Next next install fairly straightforward fairly easy process And then go back to these DLLs that you made And then we're just going to go Into the botan directory where we just installed I put it C drive button You know so it's our there's already a DLL and there's a lib file those are generated by visual studio, which we're not using We're just going to right-click and paste and then we're going to copy and replace those files That way we now have our working files that are compiled with the main W compiler Like I said if you skip that step you're going to have nothing but problems You're going to get unresolved reference errors and just all sorts of little gremlins in your code You're not going to be able to figure out what in the world is going on here Now I'm not going to lie to you botan is in Extremely complex library. It has a very good reference manual And you should actually go through this and read this and it'll talk very in-depth Hopefully on how to do certain things with this library So that is a little bit of homework you're going to have to do before we step into the next tutorial That being said This is an extremely easy library to work with and we're going to show that in our next tutorial I'm going to chunk these up into two parts simply because there is a bit of Preliminary overhead you're going to have to understand in order to work with encryption encryption is a science in itself And you have to know the difference between like a block cipher and a stream cipher We're going to cover those things in a very briefly very simply All right. Well, that's Pretty much all for this tutorial. I'm going to call this one part one of two how to compile the botan library And the next one we are going to actually use the botan library So thank you for watching. This is Brian. I hope you found this educational and entertaining


So today guys we cover an epic shield which many many people, including myself, overlooked going into this DLC, Two of Guns, Love and Tentacles. Today we take a closer look at the shield and what it's actually capable of. Has it gone guys? My name's DPJ and today I bring you another BR3 video, if you do enjoy leaving a like really helps out and subscribe if you do want to see more. So guys for all things gaming, no matter the platform you play on, check out G2A linked within that video description, with amazing deals and all you need, do check them out. So the shield, the adrenaline initiative is a shield you actually get near the start of the Guns, Love and Tentacles DLC, which most like me actually overlooked. I mean, it's early on into the DLC, what would this thing be anything special? Well guys, it is. The shield is absolutely amazing and that's because it allows you to fire well, any weapon like this. Notice that, split second reload to a point of you not really noticing it and guys you can make it even faster and I'll explain exactly how you do this in a second but before we get into that guys, more about the shield. This is a one time drop and it drops from Vincent near the start of the DLC. I believe it's the first boss fight we have to get through. So though, one time drop per campaign completion, so if you have had this in the past and just got rid of it like I did, you'll have to rerun it. I did discard mine so I simply rerun it back on True Vault Hunter mode, but it is a one time guaranteed drop and it does drop on the floor. So looking at the shield itself, on paper in my opinion it's average, no shield capacity at all, a lot like the Rafferider, but increases weapon damage and reduces incoming damage by 13% and grants 50 plus percent max health. So yeah, it takes away all shields so it's a little risky using this without the correct building place which has some part of it dedicated to health regen and it's main benefit is a plus 23% reload speed while shield is depleted, right because your shield is always depleted that's always in place. But guys, this reload effect stacks and it's simple to stack it, all you need to do is have another shield, any shield along with your adrenaline initiative and to do this to have a seeming less reload speed it's as simple as just going inside your inventory and keep switching and back and forth. So keep switching this shield for any other shield you have and just keep switching and back and forth, if you have a Rafferider and it does have added benefits like melee damage I believe that will also stack at the same time, that though I haven't tested myself so I can't confirm but I have been told by a pal. Now if you do have two of these adrenaline initiative shields, if you switch between the two inside your inventory the reload stacks stacks obviously twice as quick and like I said it results in your reload speeds being more or less nonexistent which results in some crazy results in terms of possible DPS, as for the most part many weapons in this game are stupid powerful but most due to having a slow reload speed that DPS drops like crazy this takes away that fact and what's also amazing about this is people you can fast travel and it keeps the stacks, what you can't do is though quit out and load back in or go into your inventory and switch out the shield for something else, also I will state stacking only works within one instance you're inside your inventory, so if you're inside your inventory stacking for 5 minutes, get an amazing stack, go back into your inventory and try and stack again it removes the first lot of stacks you created so keep that in mind people. So yeah guys I thought I'd just bring you this short video for the people out there interested in experimenting with this like I am and I will continue to do into the night and if I do figure out anything interesting you guys will be sure to find it right here on my channel tomorrow so stay tuned for that guys. Now share it to simply heartless for the heads up on the shield and what it's capable of so credit to him.

This is Vishwanath Chauhan, Assistant Professor, Department of Computer Science and Engineering, Valtran Institute of Technology, Solapur. Now I am here to explain the integer arithmetic. At the end of this session, the students will be able to understand the arithmetic operations on integers. So let us have a glance on how ALU works, then integer representation, then we will see the arithmetic operations on integer. Integer arithmetic. The ALU plays a very important role to perform the arithmetic operations on integer. This arithmetic and logic unit has two inputs, mainly the operand registers through which the operands are fed as a input to perform the operations. And the operations are controlled by the respective control signals. So after performing the operations such as arithmetic and logical operations on given operands, it will generate the result and result may be stored in registers or memory. So after performing arithmetic operations, the respective flags are going to set or reset. Now let us see how to represent the integer. The first method which is sine magnitude representation. So in general, for a given n bit sequence of binary number, we can find its magnitude as follows. Let us consider the given number, binary number is having the positions a0, a1, a2, so on up to a minus n minus 2 and last bit is a n minus 1. For this range, the magnitude of this binary digit is equal to, according to this formula, is equal to summation of 2 raised to i, a i, where i is varying from 0 to n minus 1. So let us consider the example 1, 1, 1, 1, 1, 1, 1, 1. So this example leaves its decimal value which is equal to 255 according to this formula. So magnitude is 255. This is what sine magnitude representation. So let us expand further. There are several convenience used to represent negative as well as positive integers. So these numbers may be positive or negative. So those can be represented like this. If the sine bit is 0, then it represents positive. If it is 1, it represents negative number. So plus 18 is equal to 0, 0, 0, 1, 0, 0, 1, 0. So this leftmost 0 indicates positive. Similarly, the negative number minus 18 can be represented as leftmost bit as 1 and other bit remains as it is. So this is the general case. Through this formula, the magnitude can be formed. For positive number, a n minus 1 is equal to 0 and this is the magnitude to find the number. Similarly, if number is negative, then a of n minus 1 bit should be 1 and the rightmost bit magnitude can be formed with the help of this formula, which is summation of 2 raise to i, a i, where i is varying from 0 to n minus 2 in both case positive and negative. Let us consider the second method which is two's complement representation. The two's method, two's complement method of a given n bit number is defined as its complement plus 1 for the range 2 raise to n. Let us consider a 3-bit number, say 0, 1, 0. So whose two's complement can be formed like this. First complement, which is 1, 0, 1, plus 1, which leads 1, 1, 0. So that's like this, represent minus 6 in two's complement. So this is an example. So first represent plus 6 as 0, 1, 1, 0. Take the two's complement, which is 1, 0, 0, 1. Then add 1 to complement of this number. Then we'll get minus 6, which is equal to 1, 0, 1, 0. So let us see the characteristics of two's complement representation. So the number range varies from minus 2 raise to n minus 1 to 2 raise to n minus 1 minus 1 for a given n-bit number. So expansion of bit length. Add additional bit position to the left and fill in which the value of the original integer. Having overflow rule, if two numbers with the same sign, either it may be positive or negative are added, then overflow occurs if and only if the result is having opposite sign. Substraction rule, which is required to find the subtraction of a given two numbers. To subtract b from a, so we need to find the two's complement of b, then add it to a. So we'll get the subtraction. So these are the three characteristics of two's complement. Pause this video, think and write the answer for this question. The question is how to represent single magnitude representation of integer and two's complement representation of integer. I hope your answer for this question. The answer is like this. Sign magnitude number can be represented. If the sign bit is 0, then it indicates the number is positive. If it is 1, it indicates negative. And two's complement can be found like this, take the two, one's complement of given number, then add one, we'll get it, two's complement. So coming to integer arithmetic, first operation, negation. Negation can be found by sign magnitude representation. The rule for forming the negation of given integer is very simple. Just have a invert of sign bit, we'll get it. Two's sign binary number, which is equal to say plus 53. So this is plus 53. So sign indicates plus negative minus 53, here sign is one. So two's complement method in which as we saw in previous slide, take the complement of given number, then add one. Negation of integer can be formed by taking Boolean complement of each bit of integer, treating the result as unsigned binary integer. Plus 18, bitwise complement, add one, we'll get minus 18, which is negation of a given number. Addition and subtraction. So register A is giving the input to add a subtractor, B is second operand. So this is switch, if switch is equal to zero, content of B register is copied forwarded to adder, if it is one, it takes complement of B and it will forward to adder. So if switch is equal to one, then one's complement plus the switch content one will be added, which forms negation of a given number, then it leads subtraction. So which uses the basic operation XOR, if two inputs are same, result is zero, else one. So if you XOR a given number with zero, you will get same number, if you XOR the given number with one, we'll get the one's complement. So this concept is used here to take the complement of a given number. So which helps for subtraction. So this same circuit is going to perform addition as well as subtraction. So next multiplication, both algorithm. So take multiplicand m, multiplier q, initialize register A is equal to zero, then insert zero to q minus one position, initially initialize the count, which is equal to n. So if q zero and q one are zero, zero and perform a plus m, if q zero and q minus one are either one, one or zero, zero, then directly go for arithmetic shift right of A, q and minus one, increase the count, decrement the count. So this will keep on repeating. If q zero and q minus one is equal to one zero, go for subtraction. At the end, we'll get, if count is equal to zero, get the result. For division, go for restoring method and non restoring method. These are the references, thank you.


Hi everyone, Joe for jaspyscasebreaks.com. Happy Wednesday, certified football coming at you. Brand new release. This is a four box, random team break number two.  So let's uh, double up, uh, uh. Thanks everyone here for getting in on it. All 32 teams are in. Let's roll it, let's randomize it. Five and a one, six times for names and teams. One, two, three, four, five, and a one. Five and a one, six and final time. Darren on the top and bottom. He's a top and a bottom. After six, and for the team six times two, three, four, five, and six. And we got the Cincinnati Bengals down to the Saints. All right, Darren with the Bengals, Brian with the Vikings, Adam with my Raiders, Nicholas with the Texans, Darren with the Steelers, Karen with her Patriots. Jonathan, you got the Cardinals, Brandon with the Ravens, Oliver with the Boys, Austin with the Falcons, Lucas with the Washington football team, Derek with the Chargers, Brandon with the Dolphins, Adam with his Jets. Look at that. Austin with the Buccaneers, Jonathan with the Fly Eagles, Fly, Karen with the G, man, Adam with the Jags. Nice. Adam B with the Jags, two different Adams in here. Ben with the Broncos, Brandon with the Bears, Lucas with the Colts, Brandon with the Rams, Ben with the Lions, Michael with the Chiefs, and the Browns, Brian with the Panthers, Adam B with the Niners. Adam B got the Niners and the Jags. It's pretty nice. Oliver Smith with the Titans, Darren with the Bills, Derek with the Packers, Seahawks for Nick, and Darren with the Saints. That's right, yeah, you got my team and your team. Adam, Adam K. So let's get all this on one screen. Let's sort alphabetically by team and feel free to trade if you'd like. Hollywood has the Cardinals up for trade. All right, remember I marked all of these, kind of hard to see right there, but we marked them with Xs so you know that these are from the same case that we're doing for random teams. So we've got three stacks of four. Let's select a die. I like that one. And we'll go one, two, three, four, five, six on the dice roll. And it's six, one, two, three, four, five, six. So these we'll save for next time. And next time we'll just go one, two, three, and four, five, six for whatever stacks we got there. All right, so there you go. There are the four boxes here. I'm gonna pause the video. When we come back, we're gonna see if there's any trades and then we'll have the four box break. Stick around, BRB. All right, welcome back everybody. A lot of trade chatter, but in the end, no deals were done here on Wednesday the 25th. Four box Ram Team Break number two. Thanks everyone for getting in. Appreciate it. Adam with that double last spot mojo. Good luck to him. Good luck to everyone. Thanks everyone for getting in. That's a local team, California. The Torrents team were just maybe just a few minutes away from us here at Jaspeas and Hermosa Beach playing South Dakota down just a single run. South Dakota's up one nothing. In the top of the six. And this Gavin Weir kid has a no-hitter with 11 strikeouts through five innings. But a couple swings in the bat, California could win this one. It's a 12 strikeout, man. A double illumination. I don't think California has lost the game in the early stages of this Little League World Series. All right, behind DJ Moore is Jalen Waddle. Ooh, what a patch. Nice patch, nice auto for the dynamic receiver. 21 out of 25, that goes to Brandon. Tried to trade, couldn't trade mojo. Ramandre Stevenson, 113 out of 125. Piece of the jersey for Karen and her Patriots. Oh, Mike Towers got some additional information for me. According to a web search, the number of innings in a Little League game is usually six. It can still be considered an official game if only four are played. Traditionally, the Little League World Series finals played on a Sunday, last Sunday in August. All games are six innings unless they go to extra. It's got it. And wow, this kid has 13 strikeouts. He's a strikeout away from a no-hitter. David Johnson, 10 out of 10. I don't know why that was flipped around, but there it is. That'll be for Texans, Nicholas. Marquez Stevenson, because the numbered cards are turned around in this box, to 399 for Buffalo. 83 out of 199, Stefan Diggs for Buffalo. And there's a Chase Young that is to 249. Chase Young going to Lucas and the Washington football team. And that will be Darren Hasbuffalo. And we got a Kenny, 88 out of 99. Cannae in Wangbu, Minnesota. That's gonna be for Brian Crouch. TJ Vacher, four out of five. TJ Vacher, rookie autograph going to the boys. Oliver Smith with Dallas. Out of fives and under, of course, get the train whistle. That's a strikeout. Strikeout, throw him out. South Dakota, Gavin Weir, no hitter. Although California only three hit South Dakota, it's a pitching duel. All right, hey, Oliver Smith, all aboard the Big Hit Express. Woo-hoo! There's Brady, stars insert. And we got a JC Horn. That is to 249. TJ Watt to 99. Stars insert, Tom Brady to 50. That's gonna go to Austin. All right, next box. Oh, you know what? This might be some fun trivia to think about. And I don't have the answer for it, but Chris Drury, Mike Towersang, won a Little League World Series as a kid in Stanley Cup as an adult. I think there's only like, you can probably count on one hand how many major leaguers have won the Little League World Series, a college World Series, and a major league baseball World Series. Does anyone know offhand? Maybe not active players anymore, but I think in the last like 20 years, there hasn't been very many, 20, 30 years or whatever, 40 years maybe. Anyone know any players off the top of your head or someone look it up if you have a second? All right, there's Elijah Molden to 249. Derek Henry to 249. I honestly, I don't have the answers by the way, so someone's gonna have to look it up and actually let me know, but there's not a lot, but it's a fun bit of trivia. I don't think Bellinger, it's a Mari Rogers to 99, Chris McCaffrey to 149, and Elijah Moore, three-color patch in autograph 98 out of 99. Yeah, Brandon, you actually, I was surprised you were gonna move, wanted to move the Dolphins because you ended up with that nice Jalen Waddle, first hit of the break. Nice, who are they, Mike? Mike Tower found an article from 2019 listing three players. Yeah, I was gonna say, there aren't very many. There's Rashad Bateman, Ravens, tried to trade, couldn't trade Mojo, 60 out of 99, new generation. Nice colors in there. There's Drew Sample, autograph, mirror signatures, 98 out of 129, Bengals, Darren Porter. There it is, one of them's Michael Conforto won the Little League World Series, wherever he's from, then won the College World Series of Oregon State and then won the 2015 MLB World Series with Mets. Wait, he won with the Mets in 2015? So 199 out of 199, Jalen Waddle. Jason Veratek's another one. In the mid-80s, won the Little League Baseball World Series wherever he's from, and then won one with Georgia Tech, College World Series, Georgia Tech, and then won the 04 World Series with the Red Sox. The other guy is, yeah, I don't think the Mets won, that's just more of a World Series appearance, right? I'm talking about, I want winners. I want players that want to win. Conforto's from Redmond, Washington State. Jason Veratek's from Monty Springs, Al Monty Springs, Florida, and Ed Vosberg, Cactusly, Tucson, Arizona, right? So I think that article might be wrong on Conforto, and there's whoop, fill your, it's a 50. All right, two boxes to go. So maybe there's only two players, maybe Veratek and this Ed Vosberg guy. I think if it's World Series appearance, you may get, I think you may get a few more players. So the article was who played. All right, I want winners. I want players that want to win. All right, next box. We've got James Robinson Duelrelleck to 149. That'll be for Adam B. and the Jags. Carson Wentz, Colts Edition to 199. Carson Wentz doesn't look too bad in a Colts uniform. Demetric Felton to 399 for the Browns. Are the Dolphins really the Patriots arch nemesis, Brandon? I feel like you're giving the Dolphins too much credit. There's LaMichele, that's kind of a cool font right there. LaMichele Piran, piece of the game, Jets to 249. I don't know, I guess, I guess AFC, that would be the big rivalry. It's like when Padres fans thinks there's a rivalry with the Dodgers and there really isn't. The rivalry is really with the San Francisco Giants. Same with the Charters too. I feel like Chargers fans think they have a rivalry with the Raiders, but I hate the Broncos far more than I do any of the other teams in the division. There's Dax Milne, Rookie Otto, 18 out of 20. Lucas Snow with the Washington football team. I guess the Dolphins do beat you guys every year in Miami. There's Trey McKinney to 299, but I think it's tough for the AFC East because the Pages have been good for so long and the other teams have been so bad for so long that there, how many meaningful rivalries has, ooh, there's an out of five, Russell Wilson. How many meaningful rivalries have come out of the AFC East? Freshman Fabric, two-color Pact Auto, Davis Mills to 299, Houston. That'll be for Nicholas. Yeah, I agree with Darren. I think Baseball has some of the better rivalries just because of the history really. Longer, more decades to establish deep, deep rivalries. Hey, here's a dark, I think this dark horse's insert is new for this year. There's four out of five, dangerous, Russell Wilson. Wilson! Nicholas L with Seattle, all aboard the Big Hit Express. Woo-hoo! And the last box, ladies and gentlemen, good luck. Final box, random team two. And another four box, random team break in the store. And we got half case picker teams in the store. Random teams are four boxes and picker team are half cases. Next picker team, picker team three, is gonna be a half case from a fresh case. Oh, that's a good coach quote, yeah. Some classic NFL coach quotes, yeah. I want winners, I want players that wanna win, Singletary, it's one of my favorites. And then of course, Danny Green, RIP. They are who we thought they were. And we let them off the hook. There's Tiffan Diggs to 199. So 199, James Robinson. You play to win the game. New Generation Relic, Jacob Harris. Playoffs, playoffs, we're just trying to win a game. That's for the Rams, that'll be for Brandon. Jared Goff to 299. Zach Wilson to 399, Josh Allen, seal of approval. And DJ Moore, this DJ be DJ Moore to 149. And there is scoring machines. Derek Henry for the Titans, that's a super short print. New for this year. Along with the certified air and certified ground. Derek Henry for Tennessee, Oliver Smith with the Titans. Mac Jones, Jersey and autograph, 87 out of 99. Karen with the Patriot, her Patriots. She usually picks the Pats. But got lucky here in this random team break I randomized the Patriots and gets the Mac Jones. So are we giving it two colors, Karen? Little bit of gray peaking there. Two color patch and autograph. There's Dez Fitzpatrick, New Generation Relic to 199. Oliver Smith, Penae Sewell, Rookie Otto, 33 out of 50. Could anchor that offensive line for the decade plus Penae Sewell. That's for Detroit, that's gonna go to Ben. We got John Bates to 299. Tom Brady and Clyde Edwards-y Lair. There you go, ladies and gentlemen. That was random team break number two from jaskyscasebreaks.com. Thanks for watching, thanks for breaking with us. I'm Joe, I'll see you next time for the next break. Bye-bye.
