Ice Bucket Challenge Leads to Significant Discovery, but Dont Call It a Breakthrough

The ALS Association is crediting the money raised through the Ice Bucket Challenge in aiding the discovery of a gene that contributes to the disease. The viral internet sensation that began in 2014 raised more than $100 million dollars for the Association, which helped fund a global effort to discover genetic drivers of the condition.Important, maybe, but not a breakthroughLot of media outlets have been calling this a breakthrough.

But not everyone. A watchdog newsletter, Health News Review, quotes Vinay Prasad, Assistant Professor of Medicine at the Oregon Health and Sciences University, who says this is no breakthrough and even if it was, the gene only affects 3% of all ALS cases. In fact, the gene was already discovered and being studied.

More on that in a minute, but first some background. The ice bucket challengeThe ice bucket challenge was the brainstorm of Pete Frates and Pat Quinn, both diagnosed with ALS. Pete was diagnosed with ALS at the age of 27.

Being a baseball family, we knew of Lou Gehrigs Disease, but thats all we knew. Nancy Frates, Petes MomBefore getting the diagnosis, Pete was living a fairly normal wife. He was married.

In fact, his wife was pregnant. Six months later, Pete had already lost the ability to eat on his own and was unable to walk. He could no longer speak.

But Pete felt the need to move forward and do what he could. He and his friend Pat launched the ice bucket challenge. The rest is history.

Public Figures and Celebs get involvedBarack Obama was challenged by Ethel Kennedy. He declined, but donated to the cause. Mark Zuckerberg, Tom Cruise, Charlie Sheen, Robert Downey, Jr.

, Oprah Winfrey, Bill Gates, Jeff Bezos, Lady Gaga, Justin Beiber, LeBron James, and Taylor Swift took the challenge. So did Former President George W. Bush, who nominated Former President Bill Clinton.

Now, with donations in hand, researchers have made what they call a significant discovery a new ALS gene. Its called NEK1. The research emerged from the largest-ever study of familial (inherited) ALS, involved contributions from over 80 researchers in 11 countries, according to the ALS Association.

Thanks to you, researchers now have an exciting new target for drug development! ALS AssociationALS typically leads to death within 25 yearsALS is a progressive neuro-degenerative disease that affects nerve cells in the brain and the spinal cord. Eventually, people with ALS lose the ability to initiate and control muscle movement, which leads to total paralysis and death, usually within two to five years of diagnosis.

While 10 percent of ALS is genetic, the other 90 percent of ALS cases are considered sporadic, or without a family history.The discovery of NEK1 highlights the value of big data in ALS research. The sophisticated gene analysis that led to this finding was only possible because of the large number of ALS samples available.

Lucie Bruijn, ResearcherGlobal collaboration among scientists, which was really made possible by ALS Ice Bucket Challenge donations, led to this important discovery. It is a prime example of the success that can come from the combined efforts of so many people, all dedicated to finding the causes of ALS. This kind of collaborative study is, more and more, where the field is headed.

Dr. John LandersUnderstanding NEK1s role in disease will provide an important new target for therapy development. The ALS Association is currently funding Dr.

John Landers and Dr. Catherine Lutz to develop models to better understand the consequences of the loss of the proteins function for the ALS disease process. These tools are important for ALS drug development.

But not everyone calls it a breakthroughIn fact, the ALS Association never called it a breakthrough in either its study or its official news release. They called it a significant discovery.Health News Review, a newsletter thats been called the watchdog of the health industry reports that the discovery of NEK1 is not new.

By all accounts, this is important basic research that may one day form the underpinnings of an effective therapy. But then again it might not and if past experience is any guide it probably wont.It took us mere moments to find two experts who after taking a closer look at the actual study results emphatically denounced the use of breakthrough to describe the findings and suggested that readers were likely to be misled.

Health News ReviewThe newsletter quotes Vinay Prasad, Assistant Professor of Medicine at the Oregon Health and Sciences University, who says this is no breakthrough and even if it was, the gene only affects 3% of all ALS cases.This is no breakthrough, and another sad and embarrassing example of academics and the media trumpeting very preliminary basic science work far beyond what they ought tothe authors do not identify a NEW gene of interest it was ALREADY implicated and even their work suggests it is a rare occurrence 3% in ALS cases. Vinay Prasad, Assistant Professor of Medicine at the Oregon Health and Sciences University Association does not mean they are a cause, former researcher at the National Institute of Health Susan Molchan told Health News Review.

That is one leap, and even if the gene did cause the disease, developing a drug, as has been attempted for Alzheimers and Duchennes for decades, is another.Still, any progress is a good thing. The disease has a 100% death rate.

Its very exciting because it shows everyone who contributed to the ice bucket challenge that their donation had an impact on the research.

After all, a physical rotation disk can't perform as well as solid state drive when it comes accessing data as fast as it canif i have an iphone and use the internet at my home connected to my wifi will it use my data gb? of data bucketWill it use your cellular data, no. However if your home Internet access data plan has caps, then the things that you do on the Internet will come out of your home Internet access data bucketHow Smart City Solutions Help Government in a Battle with Covid-19 of data bucketInitially identified in China, the new coronavirus disease outbreak is continuing to grow more than 3 months after it was first detected in December last year. Given the official name of Covid-19, coronavirus has infected more than 2 million people in more than 200 countries and regions across the globe, with more than 126.000 deaths have occurred as per mid of April 2020.Meanwhile, the number of coronavirus cases in Indonesia continues to rise. All the government efforts to flatten the curve hasn't shown significant result. In some cases, some people under surveillance (ODP), or even patient under treatment (PDP), tried to get out from hospital quarantine and it would bring more Covid-19 cases to the communities. They run because of lack information about Covid-19 from the government. The pandemic has also hit the economy of Indonesia, while the International Monetary Fund (IMF) expected worst economic fallout since The Great Depression.With the destructive power of Covid-19, every element of the society, both citizens and volunteers, must work together to help others. The government has set a budget of Rp110 trillion for a social safety net for citizens who are vulnerable to the economic impact of Covid-19. On the other hand, this large amount of fund requires accurate data on the grassroot level to ensure the fund disbursement accuracy and to avoid corruption.This is where the role of smart city technologies play an important role. The technologies that combine citizen reporting and AI-based sensors will help the government in formulating data-based decisions to cope with the pandemic based on the real situation on the field. The transparent, quick and accurate decisions will also make the communities calm down and help them get through this pandemic situation.Neighborhood leader (Ketua RT) as the lowest community organization in the country, is the person who understands the most of its communities' condition. They can report various data, such as small and medium enterprises (SMEs) players, informal sector workers, or even workers who have been laid off by their companies. They can report it directly to the government in real-time and accurate manner. Then, the report can be integrated with existing reporting citizen applications to cut-off the government bureaucracy which has been an obstacle for the distribution of the aid. Both local and central governments can access the same data bucket as it is an integrated data.Reports from the neighborhood leaders are important data for the government as it can help them to map the areas impacted by Covid-19. By mapping the problems, government can distribute the aid properly and accurately, based on each areas' needs. The data will be visualized in an integrated dashboard that can help the efficiency and effectiveness of non-medical volunteers (workforce) on the field to conduct verification and distribute the aid right on the target. Volunteers on the field are also equipped with an application that is also connected directly to the same dashboard.In addition, the smart city platforms will enable the government to use CCTV as an automatic sensor to provide reports. For example, the computer vision engine developed by Qlue enables CCTV to be a sensor by enabling them to recognize face and analyze crowds. This capability can be integrated with various data, like Covid-19 patients data, population data, and civil records owned by the government. By integrating Covid-19 patient data with computer vision, the government can act quickly if there is a Covid-19 patient who escapes the quarantine. It will also send notification to the security guard's smartphone, so they can respond to the problem in a timely manner.Enhancing CCTV capabilities with AI computer vision will also enable CCTV to detect crowds automatically. With the vision-to-speech system that is also integrated with the Internet of Things (IoT)-based speakers, it will have the ability to give warning to the crowd automatically. Other than that, the CCTV will also send notification to the nearest security officer, who will disperse the crowd directly.On the other hand, a smart city platform will also allow people who undergo a self-quarantine to give periodic updates that can be monitored by the government. By providing citizens a GIS-based application, citizens can provide daily reports about their conditions, and can immediately provide alerts to the government if their conditions are getting worse.At the end of the day, smart city platforms and solutions will help the government to effectively reduce the spread of Covid-19 by leveraging data and AI-based sensors. Both regional and central governments should be able to implement the technologies quickly to prevent the spread of Covid-19. The transparent and reliable data will recover or gain the public trust, which has been decreasing since the first Covid-19 case was occurred in Indonesia. Covid-19, inevitably, will encourage city transformation and smart city technologies implementation faster, which will lead to Indonesia smart nation

Frequently Asked Questions (FAQ) for Data Bucket
What are online cloud buckets? How is it revealing personal data?Cloud Buckets are just a modern names of Online Cloud Storage Drive Mechanisms.For Example Google Cloud and AWS both name their newly created Drives as Cloud Buckets and can contain objects inside them.The objects are our data which we keep inside a bucket. No two buckets have same name globally.------What percentage of gun homicides in the US are committed using legally-owned firearms?This article seems to give a reasonable answer to your question...MSNBC's Joe Scarborough: Tiny fraction of crimes committed with legal guns I did search the Dept. of Justice records for an answer, and though they have many interesting statistics on the periphery of your subject I didn't find anything directly related.------When will I be able to use 5 GB of additional free data on Jio Prime since there is a 1 GB daily limit?The additional free data pack of Jio when redeemed has validity only upto the expiry of current data plan.Since you are a Jio prime subscriber with a 1GB daily limit plan, the usage of 5GB additional data depends on your data usage above 1GB limit. That means if your 1GB daily limit gets exhausted, the data speed will not get reduced to 64kbps rather you will still maintain high speed data from the additional free data pack.------How is S3 implemented by AWS?S3 is an object storage protocol. Object storage, unlike Block or file storage defines files as objects. Object include data and metadata. This is a highly scalable architecture going beyond PB's scale and there are advantages over Block and File. This helps Amazon in delivering S3 for storing data. They also provide traditional storage EBS for Block and EFS for File------What should every programmer know about hash tables and hash functions?This video explains what programmers need to know about hash tables.

Does the Recent Breakthrough in ALS Suggest We Should Be Looking for More Opportunities for Ice Buck
The ALS Ice Bucket Challenge was groundbreaking, in that it turned the traditional fundraising model on its ear. It was truly grassroots in nature, allowed for flexibility in participation and donation, and was timed perfectly with the super-hot summer of 2014. It raised $100 million in donations with very little overhead or downside, complaints about water waste notwithstanding. According to Wikipedia, the success of the Ice Bucket Challenge prompted the Muscular Dystrophy Association to discontinue its Labor Day telethon to focus on new, creative and organic ways to raise money for the organization. For those who grew up with the Telethon, this was a watershed moment (no pun intended).The fact that its $100 million in donations helped lead to a research breakthrough is the icing on the cake (or ice in the bucket, again. no pun intended). In its final year, the Muscular Dystrophy television benefit (by then, not a strict telethon anymore) raised a little under $60 million.Though ALS charities tried to revive the Ice Bucket Challenge in 2015, they didnt get quite the response: only a million was raised.More Ice Bucket Challenges arent the answer. But there seems to be a great deal of potential in grassroots-style fundraising campaigns incorporating similar elements.The Ice Bucket Challenge was easy to enter, did not require a donation, and visually appealing in a Jackass sort of way. The rules were loose: which opened the door to a variety of creative and funny interpretations. You didnt even need ice, or a bucket. And you could show, or see, some skin, which made it even more media-genic.Grownups could do it, little kids could do it, it was hot enough outside to take the edge off the shivering sensation. The challenge didnt focus on the disease, although it was easy enough to Google to see the devastating effects and decide ALS research was worth supporting. Charities wishing to raise money could take cues from the Ice Bucket Challenge by following these guidelines:Make it free and low-risk to participate, and make it inclusive to people of all ages, genders, and abilities. Pretty much anyone could do an Ice Bucket Challenge, even without ice or a bucket.Dont set too many rules. Allowing participants to make up their own variants keeps it interesting, and increases engagement by upping the ante. Give participants a chance to show off. The action should be visual in nature, and something that people are going to want to share on social media, and inspire others to try it as well. If you can get celebrities into it, all the better.Make the donation plea clear and the mechanism for giving easy. The Ice Bucket Challenge was a little weak in these areas, because it was completely grassroots. If you want to try something like this for your charity, establish social channels, a hashtag, and a landing page where people can make their donation.Establish a seasonal tie-on or, better yet, an ending point. Viral phenomena have a short shelf life. The Ice Bucket Challenge didnt have this, either, but the fact that it tied in with hot weather and summer vacation helped it spread. The Ice Bucket Challenge wouldnt have worked in the winter.None of this is rocket science, so its not surprising that several charities have had success with Ice Bucket Challenge-style fundraisers. The American Diabetes Association (ADA) asked participants to add a blue streak to their hair (via hair dye or temporary extension) in honor of Diabetes Awareness Month. Streakers were encouraged to post their pic to the ADA website or social sites using the #bluestreakchallenge hashtag. You cant tell a person is diabetic by looking at them, but a blue streak of hair is pretty obvious, they said. Another extremely popular challenge, which predated the Ice Bucket by several years, is Movember, which challenges men to grow a moustache during the month of November to raise funds for diseases which affect men. (This spawned the parody challenge Mufftober, which asked women to grow hair in an area theyd typically shave, but this didnt exactly catch on.)So while charity galas, golf tournaments, and TV telethons might still have their place, the Ice Bucket Challenge showed its possible to raise millions, and promote scientific breakthroughs, through leveraging social media and the potential of the human ego. We wont be needing another Ice Bucket Challenge, but the principles behind it could be helpful indeed · Other Questions How were software engineers in the previous generation able to write complex pieces of software like Operating systems whereas I am not? I am looking into the MINIX source as a reference but still not able to piece together different components. Maybe it is because you donu2019t know enough, yet.Looking at the source of an Operating System will not teach you how it works.Designing an operating system involves researching all the requirements, studying the instruction set, interrupt mechanism, memory structure, capabilities, I/O facilities, and idiosyncrasies of the targeted hardware. Designing an organized file structure for your devices, determining what security methods to use, and more.You canu2019t learn enough to write an operating system by studying the source code. Operating systems are designed from system requirements leading to system specifications. Today there are college courses and books about operating systems that the early software engineers didnu2019t have.The u201csoftware engineers in the previous generationu201d originally had a basic need to load a single program (from cards, tape, etc.) into memory and start the program running. The programs need a way to get data (cards, tape, etc.) and to output data (cards, tape, print, etc.). The system program did this and also supplied a generic way for a program to access the input and output devices so they didnu2019t have to be programmed for each device separately. The original digital business computers were incredibly expensive, had large word sizes (often 36 bit or more) with instructions that were able to access all of word (not byte) addressable memory without requiring additional registers to be loaded first to access memory. Of course there wasnu2019t that much memory, but neither was there a lot of memory in the 8 bit PCs. The machine design allowed system developers to concentrate on system functionality without having to deal with the primitive addressing methods needed for the PC. So what was involved in programming a Operating System:With the inclusion of memory protection architecture and other advances, the systems design added methods to split/partition memory into fixed sections allowing more than one program loaded in memory at a time. Also necessary was a way to decide which partition is active, for how long, what to do when a running program had to wait for a request (i/O or otherwise) to complete, how and when to make another partition active and have the current running program u201csleepu201d, how and where to save information from a u201csleepingu201d partitionu201d and how to wake it up. Also needed was the ability to only allow designated programs from accessing certain devices and not allow other programs to do so. With disk drives used as random access devices, a method was needed to identify the part of the disk being used. The concept of a file structure was invented. An entry in a file structure pointed to the beginning of a file and a way was also needed to get to any desired part of a file. Programming needed to be added to an operating system to support all this. Eventually, files were assigned ownership to users and programming was added to implement security protocols to do this as well as assign read/write protections to files.Instead of splitting memory into fixed sections, system designers learned to allocate memory as necessary to individual programs. A program needing more memory would acquire it from the system from a pool of unused available memory and release memory to the system to make it available to other programs. For this to happen, there had to be a way for memory hardware to be accessible by the assigned program but still be protected from other programs.For this, memory was u201csplitu201d into allocatable blocks called pages (or segments). A table was used as part of a users environment to point to assigned memory areas and memory translation hardware used the table to automatically translated a program memory reference to an actual memory address. Some hardware even implemented two address mapping tables, one for instruction execution addresses and one for data access addressing. Among the benefits was the prevention of a runway program from modifying itself. If a program modified address xxxxx, it would not succeed if xxxxx was the address of an instruction. A programming error would not be able to flow or branch to an address used for data. Unfortunately, some good assembly or machine language programs were intentionally written that way and they no longer worked. Address mapping tables were expanded to allow for having much more memory than an instruction address or register could reach.As disk drives became faster it became practical for an inactive program (waiting for something) to moved out of memory to the disk drive. System developers invented a swap area or pagefile area and programmed how it associated user program memory areas with locations on the disk drive so that it could be reloaded into memory. The memory mapping tables made it possible to restore swapped out programs to different memory addresses. It also became possible to put just part of a program in memory and when a program wanted to accessory instructions or data not in memory, an exception (or interrupt) would occur, the system would detect the situation, find the desired part of the program in the swap area, loaded it in, and let the program continue running. Considering the speed of everything in a computer, an interactive user usually does not realize any of this happened. All this is just part of what an operating system does and unless the source code is very heavily documented (it never is), and the documentation is up to date (it never is), it is unlikely that you would be able to learn much from reading the code
Design Scheme of Multi-channel Voltage Measurement Based on Stm32
Design Scheme of Multi-channel Voltage Measurement Based on Stm32
This design proposes a design scheme of multi-channel voltage measurement based on STM32 chip, and the measurement range is between 0-10V. The built-in A / D of STM32 samples the multi-channel voltage values to obtain the corresponding digital quantity. Then the corresponding analog voltage value is obtained according to the proportional relationship between digital quantity and analog quantity, which is displayed by TFTLCD display equipment, and the multi-channel collected data is stored in SD card.1. IntroductionIn recent years, data acquisition and its application have attracted more and more attention, and data acquisition system has developed rapidly. It can be widely used in various fields.Data acquisition technology is one of the important branches of information science. Data acquisition is also a process of obtaining object information from one or more signals. Data acquisition is an important link in industrial control systems. It is usually realized by some single chip microcomputer systems with relatively independent functions. As an indispensable part of the measurement and control system, the performance characteristics of data acquisition directly affect the whole system.Voltage measurement is the most universal. It is of great significance to study and design methods and instruments to improve voltage measurement accuracy. In the design of voltage measurement, single chip microcomputer as controller is the core of the whole design. In addition, there must be an analog-to-digital converter (ADC) in the design. ADC is used to directly collect analog voltage and convert analog signal into digital signal. It directly affects the accuracy and speed of data acquisition.2. System overviewThe microcontroller of this design adopts STM32 single chip microcomputer.STM32 Series MCU is designed based on the Cortex-M3 core of arm company. Its clock frequency reaches 72mhz. It is a high-performance product among similar products. It has the advantages of high performance, low cost and low power consumption. It is a good choice in embedded application design. The A / D converter in the design adopts STM32 built-in ADC. STM32 ADC is a 12 bit successive approximation analog-to-digital converter.It has up to 18 channels and can measure 16 external and 2 internal signal sources. The A / D conversion of each channel can be performed in single, continuous, scanning or intermittent mode. The conversion results can be stored in the 16 bit data register in left or right alignment. The maximum input clock can reach 14mhzThis design can measure the voltage value of 8 channels, the measurement range is 0-10V, and the display error is ± 0.001V. LCD displays the voltage value and waveform in real time, and microSD card synchronously stores the data. The system principle block diagram is shown in Figure 1.Design scheme of multi-channel voltage measurement based on stm323.3 LCD control circuitThe LCD used in this design is 2.4 inches, 320 & times; 240 resolution. The LCD module is controlled by the FSMC interface of STM32.FSMC (flexible static memory controller) can be changed into static storage controller. It is a unique storage control mechanism of STM32 series high storage density microcontroller with internal integration of flash of more than 256Kb and suffixes Xc, XD and Xe. By setting the special function register, FSMC can send corresponding data / address / control signal types according to different external memory types to match the speed of the signal, so that STM32 series microcontrollers can not only apply various external static memories of different types and speeds, Moreover, it can expand a variety of different types of static memory without adding external devices, so as to meet the comprehensive requirements of system design for storage capacity, product volume and cost.In STM32, one end of FSMC is connected to core Cortex-M3 through internal high-speed bus AHB, and the other end is an external bus for extended memory. After the access signal of the kernel to the external memory is sent to the AHB bus, it is converted into a signal conforming to the communication protocol of the external memory through the FSMC and sent to the corresponding pin of the external memory to realize the data interaction between the kernel and the external memory. FSMC acts as a bridge, which can not only convert the signal type, but also adjust the signal width and timing, so as to shield the differences of different storage types and make them no difference to the kernel.FSMC can connect devices such as nor / PSRAM / NAND / PC card, and has FSMC_ A [25:0] has 26 address buses and FSMC [15:0] has 16 data buses. In addition, the extended storage space of FSMC is divided into 8 blocks. Select the block of the operation through the address line. In this way, the LCD will operate as a memory with one address space.3.4 SD card drive circuitThe SD card used in this design is microSD, also known as TF card. MicroSD card is a very small flash memory card, which is mainly used in mobile phones. However, due to its small volume and the continuous improvement of storage capacity, it has been used in GPS devices, portable music players, digital cameras and some flash memory disks. The pin diagram of microSD card is shown in Figure 9.MicroSD card, like SD card, has SPI and SDIO operation buses. Compared with SDIO bus, SPI bus has simple interface, but its speed is slow. We use SDIO mode.MicroSD card has 4 data lines in SDIO mode.In fact, microSD has 1-wire mode and 4-wire mode in SDIO mode, that is, 1 or 4 data lines are used respectively. Of course, the speed of 4-wire mode is faster than that of 1-wire mode, but the operation is more complex. The 4-wire mode of SDIO is used in this design. The hardware connection diagram of microSD card is shown in Figure 3.STM32 MCU Chinese official websiteSTMicroelectronics / St / STM
How Does Temperature Affect the Speed of Sound?
How Does Temperature Affect the Speed of Sound?
As other answers show, the speed of sound is slightly influenced by temperature.Much more interesting is the influence of gradients in temperature! The usual distribution of temperature at different heights is: high at ground level, decreasing upwards. This profile, with slightly higher sound velocity at ground level causes wave fronts to curve upwards. Sometimes the temperature profile is inverse, from ground level to a certain height, in the order of hundreds of meters. This inversion layer acts as a reflector, causing sound to propagate over much larger distances.It is not the speed as such, but the differences in speed that have important influence on sound propagation.1. How to increase my running speed?No, leaping prime does now not make you a quicker runner. Speed is muscular so you will do whole frame paintings along side plyometrics, which can be exceptional varieties of bounding and leaping to construct explosive force. To get greater at going for walks you ought to run. If you are employed on lifting and doing the plyometrics you are going to have the groundwork to upgrade your going for walks. What form of going for walks are you running for? If it's soccer then you definitely will have to coach for brief bursts of velocity. If it's one other game you have got to appear on the distances required on your game. A huge aspect of velocity it response. That manner the begin. Whether it's out of the blocks in a race, or attending to a fly ball within the outfield. Speed is vigor so that you ought to be ready to loosen up rise up tall, maintain your elbows at ninety levels, swing them directly entrance to again, and now not throughout your frame. Land at the balls of your ft.2. Water flows through a 1.5 cm diameter pipe into a 275 liter bathtub, which it fills in 5 minutes. What is the speed of the water in the pipe?Mass of 275 litres of Water divided by 5 minutes x 60 seconds = Time of 300 secondsMass Flow Rate of 0.9166 litres per secondThis is excessive amount of water in Speed or Velocity to fill a bathtub in 300 seconds. See IPHE & CIBSE CoP & Technical Guidance on maximum flow rate for 15 mm smooth wall copper pipework. The water pressure is another factor is consider.Water flows through a 1.5 cm diameter pipe into a 275 liter bathtub, which it fills in 5 minutes. What is the speed of the water in the pipe?.3. Not getting the download speed I should be getting?you download a file to what ? a phone or a computer? ethernet or wirelessly ? you need to be more clear on how to ask a question, even with my godlike powers i cant read your mind4. Need help gaining speed/trimming fat?challenging task. browse in google. that will may help!5. Why are people so insistent that speed of light is constant for all observers and is the maximum traveling speed?In special relativity, when the speed of light is constant for everyone, time can be different. When different travellers or observers have light remain constant, their time can change to allow for this. So try to wrap your head around the fact that different observers can have differences in time, and this allows the speed of light to remain constant for all observers.6. fur nice fan motor Polly have to be smaller to make the fan go faster?Motor pulley larger or driven pulley smaller will increase speed7. What are the technical factors in a processor that determine its speed?Clock Speed of the Processor and its primary cache size determines its speed in terms of throughput8. Is faster than the speed of light possible?well ist just a theory so it could be or couldnt be true.....einstien said if we could go the speed of light then we cold time travel...other people say it is still expanding....what i want to know is how can all of that crap fit into somthing the size of a pin head lol.9. How to train for faster picking speed on guitar?Assuming we are talking about alternate picking, there are basically two exercise methods for building speed.The first and the better known one is to start slow. Set your metronome to a comfortable tempo and play the exercise a few times. Then go up 2 bpms or so and repeat. Continue alternating between plus two and minus one. Back down some 10 bpm when you hit your limit and work your way up from there again. You can go up 10 bpm or so from time to time just to see how it feels. The second one is to practice in bursts. Start with two notes and play as fast as you can. Then add the third and continue from there. This method is not as well known as the first one but is every bit as useful. You can also start from the most difficult spot on the exercise and add notes on both sides.Practicing scales only is probably not the best way to go. There are specially crafted exercise sets to build speed that isolate common patterns. Troy Stetina's book Speed Mechanics contains one such set.In terms of technique, on your left hand, only apply enough pressure to avoid buzz. You will get tired very quickly if you exert more force than necessary. The lighter your left hand touch is, the easier it is to play fast. It's easier said than done but that's the whole idea of practicing.On your right hand, I would not worry that much about wrist vs. elbow unless you are aiming for Guiness speed record. Wrist movement is probably a bit better but there's nothing wrong with a combination of wrist and elbow. Guitarists argue about it all the time but there are superb guitarists in both camps which proves that both techniques are equally viable. Just avoid finger movement, it does not work for fast playing

And what is a BLU RAY DVD?Bluetooth is a wireless technology for connecting electronic devices to each other. For instance there are Bluetooth Headphones, Bluetooth Cell Phone Ear Pieces, etc... If you want to be able to use the Bluetooth Ear Pieces with your cellphone, your cellphone must be Bluetooth compatible. WiFi is a method of connecting to the internet wirelessly. For instance many big cities may have "WiFi Hotspots". If you are in these WiFi Hotspots and you have your laptop or any other device that can connect to the internet wirelessly, you can surf the web wirelessly as long as you are in that particular area. And Blu-Ray is Sony's High Definition format disc. The difference between Blu-Ray and Regular DVD is that Blu-Ray can produce 1080p HD quality picture and Blu-Ray can hold more data. A Single Layer Blu-Ray disc can hold 25GB and a Dual Layer DVD can hold 50GB. A standard DVD can only hold around 8.5GB total. Basically if you have a HDTV, Blu-Ray would be the best choice for getting the best picture quality with clear, crisp viewing quality.
Which Is Better, WiFi Or ZigBee Wireless Technology
Which Is Better, WiFi Or ZigBee Wireless Technology
Wireless replacing wired has become an irreversible trend, which can also be said to be a new industry. At present, there are two technical camps of ZigBee and WiFi in the field of smart home, and WiFi and ZigBee have their own advantages in wireless technology. Among the most popular wireless technologies in the industry, WiFi technology and ZigBee technology are the most worthy of competition. So which is more advantageous, WiFi or ZigBee? Who will become the mainstream in the future? This is worth discussing.WiFi: WiFi technology is the fastest transmission technology at present. The product cost is low and it is more popular in current life. However, the devices that can be connected with WiFi are limited. The actual scale of adding WiFi network to devices generally will not exceed 16. In the development of, the number of switches, lighting and home appliances will certainly be far more than 16, so WiFi has its advantages, but it has great limitations, Limited development.ZigBee is a two-way wireless communication technology with low complexity, high security and short-range transmission. It has the characteristics of strong scalability and can be embedded in various household devices. ZigBee also has advantages in security.1. The future smart home network will be a smart network, which can sensitively perceive the changes of data and traffic of each node; Be able to intelligently allocate, repair and deal with network resources; It has the attribute of "self-learning and self-organization".. However, in the practical application of families, switches, lighting, curtains, anti-theft devices, etc. will not move after installation.2. ZigBee supports up to 65000 nodes, but can WiFi connect more than 100 devices? The answer is No. So large capacity is good.For example, LVMI smart home, that is, Xiaomi's smart home brand, basically supports ZigBee protocol.When it comes to LVMI, I recommend their smart gateway. The smart home market is very messy. Sometimes we are excited to buy it and find that it does not support it. Therefore, when we buy it, we should see what the device supports or does not support. Of course, the best thing is to buy a gateway with high compatibility. LVMI's gateway product not only supports ZigBee protocol, but also is compatible with homekit. This product supports 32 aqara devices of green rice, which can be connected with Apple's "home" app. After that, it can control the associated devices on IOS devices and Siri directly. I think most young people now use fruit machines to compare prices. In this way, it is still very friendly to most IOS users. For fruit powder users, the biggest advantage of this product is price. At present, the smart home products supporting homekit on Apple's official website are very expensive. Even a simple smart socket costs 295 yuan. Through the aqara gateway of LVMI, the cost of access equipment can be reduced.Well, comprehensive comparison, WiFi is relatively more convenient, but ZigBee will be more stable and support more devices. If you only want to use one or two smart devices, WiFi can be used. If you want to create a complete set of smart home ecological chain, it is obvious that ZigBee is more in line with your requirements. Xiaobian is more optimistic about ZigBee. After all, home is developing towards the trend of comprehensive intelligence, Technology with multiple devices can ensure this. No matter what kind of technology, we hope to constantly update and improve, and making our products convenient is the king.

Smart Home Promotes Building Intercom into Thousands of Households, with Large Stock and Incremental
In the large densely populated cities of Beijing, Shanghai, Guangzhou and Shenzhen and the rising second and third tier cities, the housing demand is increasing year by year. The huge floating population not only promotes the rapid development of low-end real estate resources in the first tier cities, but also extends the complex industrial chain around the buildings. In particular, the development slogan of "smart city" put forward by the state in recent two years gives hope to the market that lives on security products around buildings in addition to real estate developers.Smart home promotes building intercom into thousands of householdsAt present, more and more building intercom manufacturers begin to go deep into the field of smart home and combine building intercom system with smart home system. This is reflected in the construction of "digital building" and "smart home industry ecosystem":Combined with the smart home system, in addition to the traditional intercom unlocking function, the building intercom also integrates many convenient functions such as SMS notification, mobile app remote control, security alarm, indoor monitoring and viewing, elevator call, home control, information home and so on.Building intercom and smart home complement each other, further improving the value-added space and cost performance of both, thus bringing huge space for function expansion.In the future, it is expected to take advantage of the upsurge of smart home to develop rapidly in the wave of home intelligence, and will carry more home control functions.Smart community derived demand brings new business opportunities for building intercomIn addition to the smart home, the building intercom system, as the entrance of the smart community, realizes the extension of multiple functions such as identity confirmation, access control, security monitoring, human-computer interaction and so on by combining AI technology.The consumer demand derived from the smart community can be said to bring new business opportunities to the building intercom industry. In the process of continuous promotion of the smart community, many building intercom enterprises see the future business opportunities and begin to make corresponding layout and planning on products and solutions. Using information means, Internet and Internet of things technology, develop community oriented Internet of things system and information platform, and provide real-time, fast, efficient and low-cost Internet of things, interconnection and intelligence for the community on this basis. For example, it launched smart community management, smart life services, smart travel and other related solutions, and continued to pay attention to the field of community and personal security.High, middle and low-end take all stock and incremental market space is largeAs an upstream industry of real estate, building intercom has significantly increased the demand for medium and low-end building intercom products under the condition that the state vigorously promotes the construction of affordable housing and indemnificatory housing.With the implementation of smart city construction, the demand for high-end building intercom products is also increasing day by day. The application of high-definition visualization and face recognition in the field of building intercom is accelerating.At the same time, after more than 20 years of development, many communities equipped with building intercom in the early stage are facing problems such as disrepair and backward configuration. Therefore, the equipment renewal demand of old communities has also become a new round of market growth point of building intercom system.Overall, China's housing market will continue to develop. According to the relevant development strategies of the State Council, China will build 10 billion square meters of housing by 2020. For building intercom enterprises, there is a large development space for building intercom related products in both stock market and incremental market.Conclusion: in a word, opening up the integration and docking with comprehensive life service platforms and community operation platforms such as third-party payment, smart city, video surveillance, community o2o e-commerce, smart home and community elderly care, that is to provide overall solutions for communities and families, which has become the future development trend of deepening reform, transformation and upgrading of building intercom enterprises. Moreover, with the gradual improvement of community infrastructure, building intercom enterprises also need to change from the role of product provider to the role of supporting service provider.
