Huawei plans to advise Nvidia in China. It has a new GPU for theory that in theory is extremely powerful

by

Huawei is putting all the meat on the grill to absorb so much share in the Chinese GPU market for artificial intelligence (AI) as I can. And it is that the entry into force of the last US sanctions package is compromising with all probability Nvidia leadership in China. The US Department of Commerce It has imposed restrictions to the export to the country led by Xi Jinping of The H20 GPUand this in practice means that this chip presumably will not reach the Chinese clients of Nvidia. This last company has announced that this ban will cause a hole in its accounts of 5,500 million dollars Due to the commitments linked to the H20 GPU that had already acquired the reserves of this chip that it will not finally satisfy. Some of the Chinese companies that have bought large amounts from the H20 chip to NVIDIA and who presumably planned to continue doing them are Tencent, Alibaba or Bytedance, but at the current situation they will have to resort to an alternative. And Huawei has put it on a tray. The GPU Ascend 910D aspires to snatch the leadership in performance from Nvidia Huawei reacted immediately to US sanctions. And is that just a few hours after the entry into force of the new regulation of the Department of Commerce He presented his chip for the ascend 920a solution that is clearly destined to occupy in the Chinese market the gaps that the NVIDIA H20 GPU is going to leave. This proposal will enter large -scale production during the second half of 2025 using 6 NM integration technology that have presumably developed elbow with Huawei elbow and SMIC. Until now Huawei wanted to get his hardware to dominate the inference processes in AI However, this is not the only asset that Huawei has to increase its market share both in China and beyond its country of origin. And is that, According to Reutersthis company is preparing to start the testing and validation phase of a new GPU for AI: The Ascend 910D chip. Unlike the GPU Ascend 920 that, as we have seen, presumably aspires to compete with the NVIDIA H20 chip, the GPU Ascend 910D seeks to overcome the performance of the chip NVIDIA H100. If this movement is confirmed, already priori this information is reliable, it will be evident that Huawei will have chosen to fight in all hardware market segments for the nvidia. Until now this Chinese company wanted to get its hardware dominate the inference processes in AIand not the training of the models, as Georgios Zacharopoulos, a senior researcher of AI who works on the acceleration of inference in the Huawei laboratory in Zurich (Switzerland) points out in this statement. “The training is important, but it only happens a few times. Huawei focuses mainly on inference, which will ultimately give us access to more customers,” says Zacharopoulos. Inference is broadly the computational process carried out by language models with the purpose of Generate the answers which correspond to the requests they receive. In any case, the information we have reflects that the GPU Ascend 910D will allow Huawei to compete with the chips for the most advanced NVIDIA both in inference and in training.

We have been waiting for years at airports for years. Tiktok’s “airport theory” believes that it has been a mistake

by

If you fly you will frequently be listening to it. The airport must be reached in advance. How much it depends largely on the city from which you take off and what your destination is, but usually the travelers are recommended that they be in the terminal with a margin of 90 minutes either two hours. And that at least. If fate is a distant country, like the US, that margin is quite superior. But … what if that wait could be reduced to 15 minutes? Just listening to it up the pulsations, but in Tiktok there are people (quite) determined to demonstrate the validity of a “Airport Theory” that holds that: that if you have done the Chek-in Online, you don’t have to bill suitcases and the trip is national, 15 minutes is more than enough not to lose flight. Not suitable for cardiac. “Traveling is a pleasure,” as I said Gloria Fuertes. But also a source of stress, nerves and hurry. Especially if you travel by plane. Hence operators Like Aena and the own airlines They advise to present themselves well in advance at airports. The exact time can vary from one case to another, but it usually moves between 90 minutestwo and a half or even the four For some destinations. In Tiktok there are enough people convinced that, at least in certain cases, they arrive with the terminal about 15 minutes before shipping or Even from takeoff. And is so sure of it that has begun to prove it During your own trips. @Michael.dicanzo Can Airport Theory Survive The World’s Busiest Airport ?? 👀✈️🤔 #Airportheory #Atlantaairport #Challenge ♬ Original Sound – Michael Dicostanzo The “Airport Theory”. The trend has been baptized as Airport Theory (“Airport Theory”) and has gained strength especially among Anglo -Saxon passengers. He arrives with searching The hashtag In Tiktok to verify that there is a good handful of videos of people (including Tiktokers with millions of followers) committed to demonstratein their own meats that can occur at the airport with much less in advance of what operators and airlines advise and yet to climb their airplanes without problem. Moreover, the phenomenon has won enough draft to jump from the networks to the generalist media, with reports in US chains and magazines such as The CNN, Fox News either Wired. Some of the videos of Influencers who speak of the theory, like the one who Michael Dicostanzo dedicated him A few days ago, hundreds of thousands of visualizations accumulate. But … What do you propose? Very simple. Roughly, the “airport theory” holds that until now you have been malicanting hours of your life at airports without any need. At least in certain cases. His hypothesis is that if the passenger has already performed the Check-in Online and only loads with hand luggage (so you don’t have to bill suitcases) you can reach the airport 15 minutes before embarking. According to the viral trend that is enough margin to pass the security controls, travel the distance to the boarding row and access the plane. All this, of course, without losing the flight. “Is it really necessary Betsy Grunch wonderswith 2.4 million followers on Tiktok. @itslexismith Testing Airport Theory At Lax ♬ Original Sound – Lexi Smith “I don’t think it’s necessary”. In An interview Recent with the CNN Grunch remembers that she had to check “the airport theory” one day that traffic and luggage problems led him to perform at the HartSfiel-Jackson International Airport, in Atlanta, only 26 minutes before his boarding time. As good TiktokerHe took the phone and recorded what came later: a race not suitable for cardiacs that allowed him to take his flight on time. Other influencer who wanted to verify it was James Shaw, although he opted for An experiment Sater: he went with his wife to a Florida airport with 90 minutes in advance of rigor and then used a stopwatch to calculate how long they took to reach his boarding door. He paused him after 13 minutes. “I think traveling can be very stressful and that’s why we say ‘I need to be there three or four hours earlier, or whatever it is.’ I don’t think it is necessary to do it,” Add Shaw. Of course, he only wore hand luggage and used a service that speeds up the procedures in the terminal. Like Grunch, he also recognizes that they would never test the theory on an international, more expensive trip and in which security controls can be more complicated … and long. The debate, served. Does “airport theory” work? In Tiktok you can find comments and videos both for and against. Also of course pieces of Tiktokers They have ended up seeing how They remain on land. Beyond recordings such as Dicostanzo and the debate that has emerged in networks, there are a few data that help to understand the scope of the trend … and some of its repercussions. A few days ago Wired needed That the “airport theory” accumulates more than 400 million visits in Tiktok, a sudden interest that seems to have coincided with a considerable rebound by Google Trends in the searches of “I have lost my flight, what do I do?” The truth is that airlines usually advise to present themselves at airports with a couple of hours In advance, enough to prevent an unforeseen event, such as a routine luggage control, bottling or tail in access to the terminal, can wait for the trip. “I think it’s nonsense”. Those who seem to be clear are the professionals who work at airports, a priori little supporters that travelers appear 15 minutes before their shipment. The reason: the risks. “The waiting times of security controls can vary from one airport to another, and even from one day to another, within the same terminal,” Explain to the CNN A spokesman for the Dalls/Fort Whorth aerodrome. With a couple of ‘mattress’ hours a traveler can prevent “unforeseen” of the last minute for her … Read more

We have a new “theory of all” to understand Alzheimer’s. Your key is in small granules

by

Creating “theories of all”, unified models that explain various phenomena associated with a scientific field, is not exclusive heritage of physicists. The fight against some diseases can also benefit from models that help us understand their causes and consequences and the processes that mediate. New model. Now a group of researchers has devised a new modela theory that tries to explain Alzheimer’s disease through a “unified explanation of molecular chaos” that derives in this neurodegenerative disorder. According to this new theory, the disease and its symptoms would derive from a collapse of the transport system in charge of moving molecules between the nucleus and cell cytoplasm. This new theory can help simplify a topic as complex as Alzheimer’s. However, its authors remember that this disruption is still extremely complex, with more than a thousand genes involved in it. “Our proposal, focused on the rupture of communication between the nucleus and the cytoplasm leading to massive disruptions in gene expression, offers a plausible framework to understand the mechanisms that lead to this complex disease,” Explain in a press release Paul Coleman, co -author of the new model. A granular problem The model places the formation of chronic stress granules at the beginning of this process. These are clusters of proteins and RNA chains responsible for generating stress in the cell. Stress granules are usually generated temporarily. Its original function is to respond to cell stress by leaving some processes until the cell can recover. Once its duty has fulfilled and the stress disappeared, they dissolve. The problem unleashes when these granules become chronic, which leads them to catch other molecules, making it difficult for them to move between the nucleus and the rest of the cell. From inside out. The model starts from this trigger to explain with it the disease and its consequences outside the cellular unit. And it is that the changes that occur at the cellular level end up affecting cerebral synapses, metabolism, protein processing and cell survival, as explained by the model responsible for the model. The details of the new model were published In an article In the magazine Alzheimer’s and Dementia: The Journal of the Alzheimer’s Association. A disease with many faces. Alzheimer is one of the most intriguing diseases, Explain the responsible team of the new model. In part, they point out, this is because it takes the appearance of various diseases made one, with symptoms that include memory loss and cognitive deterioration, but also changes in personality and in our same internal biology. This complexity, continues to expose the team, is partly responsible for how extremely difficult it is to study this disease. Models like this that schematize their processes, can serve future researchers to find new routes of action that become more effective therapies when facing the symptoms of Alzheimer’s or, even, the same disease.

wants to overthrow Einstein’s special theory of relativity

by

Quarks, the elementary particles that make up the protons and neutrons of the atomic nucleus, are fermions. And electrons, too. There are several types, although physicists like to talk more about ‘flavors’: above (up), below (down), charm (charm), strange (strange), top (top) and background (bottom). The most frequent in ordinary matter are the up and down quarksalthough the one that interests us the most in this article is the top quark for a very interesting reason: it is the heaviest elementary particle that we can find in nature. An interesting note given that we are moving in the field of fermions: supersymmetry is a theoretical model of particle physics that proposes the existence of a hypothetical particle that is paired with each of the fundamental particles that we know. It seeks to explain the existing relationship between the bosonswhich have a spin with an integer value, and fermions, which have a half-integer spin. However, it is important that we do not overlook that it is a hypothetical theoretical framework that, therefore, has not yet been observed in nature. Not even experimentally. CERN has investigated whether the top quark respects the special theory of relativity The quantum mechanics and the special theory of relativity formulated by Albert Einstein constitute the heart of Standard Model of particle physics. Until now, this theory by the popular German physicist has stood the test of time undaunted, but scientists do not miss the slightest opportunity when it comes to putting it in trouble. And it is ideal because it is one of the most effective strategies when what is sought is to go beyond the solid walls of the Standard Model in the hope of develop new physics. Some specific models of string theory propose that at very high energies special relativity will no longer be valid. Lorentz symmetry lies at the very core of this model. Broadly speaking, this property justifies that the experimental results are independent of orientation and speed with which the experiment is carried out in the space-time continuum. It seems like a complicated concept, but if we think about it a little carefully, it is not so complicated. Be that as it may, what is really important is that so far all the experiments that physicists have carried out have supported Lorentz symmetry. However, and here comes the most interesting part, some theories, such as specific models of string theory, propose that at very high energies special relativity will no longer be valid and experimental observations will depend on the orientation of the experiment in space. -time. If so, the Lorentz symmetry would be broken. On paper, it should be possible to identify this break in the energy level that physicists work with in the CMS particle detector from CERN (European Organization for Nuclear Research). For months, CMS experiment researchers have meticulously analyzed the properties of the top quark pairs produced in the collisions at the LHC (Large Hadron Collider). And their result is very interesting: the production rate of top quark pairs remains constant even though the direction of the LHC’s proton beams and the average direction of the top quarks produced in the experiment change depending on the time of day due to the Earth’s spin on its axis. This means that there is no preferred direction in the space-time continuum capable of conditioning the production of top quarks. And, therefore, the Lorentz symmetry is still intact. And the special theory of relativity is still valid.
