Submission + - Nvidia and AMD to pay 15% of China chip sale revenues to US government (archive.is)

Submitted by Anonymous Coward
An anonymous reader writes: The Financial Times reported on Friday that the commerce department started issuing H20 export licences on Friday, two days after Nvidia chief executive Jensen Huang met President Donald Trump. The US official said the administration had also started issuing licences for AMD’s China chip.

The quid pro quo arrangement is unprecedented. According to export control experts, no US company has ever agreed to pay a portion of their revenues to obtain export licences. But the deal fits a pattern in the Trump administration where the president urges companies to take measures, such as domestic investments, for example, to prevent the imposition of tariffs in an effort to bring in jobs and revenue to America.

Submission + - Cannibal AIs Could Risk Digital 'Mad Cow Disease' Without Fresh Data (sciencealert.com) 1

schwit1 writes: A new study by researchers from Rice University and Stanford University in the US offers evidence that when AI engines are trained on synthetic, machine-made input rather than text and images made by actual people, the quality of their output starts to suffer.

The researchers are calling this effect Model Autophagy Disorder (MAD). The AI effectively consumes itself, which means there are parallels for mad cow disease – a neurological disorder in cows that are fed the infected remains of other cattle.

Without fresh, real-world data, content produced by AI declines in its level of quality, in its level of diversity, or both, the study shows. It’s a warning about a future of AI slop from these models.

“Our theoretical and empirical analyses have enabled us to extrapolate what might happen as generative models become ubiquitous and train future models in self-consuming loops,” says computer engineer Richard Baraniuk, from Rice University.

“Some ramifications are clear: without enough fresh real data, future generative models are doomed to MADness.”

Submission + - New charger could double the service-life of Li-Ion batteries 1

NewtonsLaw writes: Lithium-Ion (LI) batteries are the backbone of much of our modern technology. They're in our phones, our laptops, our smartwatches and even the EVs that are increasingly appearing on our roads. One of the problems with LI technolgy however, is the very finite life of those batteries.

In the case of an EV, the battery pack represents a very significant portion of the total price you pay when buying one. Right now, the life of EV batteries is generally considered to be at least eight years, under normal use. But what if that could be doubled — simply by changing the way those batteries are charged?

This announcement by researchers in Europe indicates that the service life (ie: the number of charg/discharge cycles) of LI batteries could be as much as doubled, through the use of a pulsed current charging technology.

The standard charge method for LI cells is to deliver a constant direct current (DC) until the voltage of the cell rises to around 4.2 volts, at which time the voltage is maintained at a constant level and the charge current allowed to fall off. Once the charge current reaches a predefined minimum level, the cell is considered charged.

The new pulsed current method does not use DC but instead opts to recharge by way of intermittent pulses of current. This is not a new charging technology although it's not the norm for LI cells. Pulsed current chargers have been used on older chemistries such as nickel-cadmium in order to reduce/eliminate the formation of dendrites that would otherwise create short-circuits or significantly increase the self-discharge rate. Applying this tech to recharging LI cells seems to be a significant game-changer, if the lab results are duplicated in "the real world (TM)"

Doubling the life of your EV's battery or even your smartphone's battery is no small thing.

Submission + - Akira Toriyama, creator of Dragon Ball manga series, dies aged 68 (theguardian.com)

AmiMoJo writes: Akira Toriyama, the influential Japanese manga artist who created the Dragon Ball series, has died at the age of 68. He died on 1 March from an acute subdural haematoma. The news was confirmed by Bird Studio, the manga company that Toriyama founded in 1983. “It’s our deep regret that he still had several works in the middle of creation with great enthusiasm,” the studio wrote in a statement. “Also, he would have many more things to achieve.” The studio remembered his “unique world of creation”. “He has left many manga titles and works of art to this world,” the statement read. “Thanks to the support of so many people around the world, he has been able to continue his creative activities for over 45 years.”
