Large-scale kinetic simulations of colliding plasmas within a hohlraum of indirect-drive inertial confinement fusion

The National Ignition Facility has recently achieved successful burning plasma and ignition using the inertial confinement fusion (ICF) approach. However, there are still many fundamental physics phenomena that are not well understood, including the kinetic processes in the hohlraum. Shan et al. [Phys. Rev. Lett. 120, 195001 (2018)] utilized the energy spectra of neutrons to investigate the kinetic colliding plasma in a hohlraum of indirect drive ICF. However, due to the typical large spatial-temporal scales, this experiment could not be well simulated by using available codes at that time. Utilizing our advanced high-order implicit PIC code, LAPINS, we were able to successfully reproduce the experiment on a large scale of both spatial and temporal dimensions, in which the original computational scale was increased by approximately seven to eight orders of magnitude.

This soft brain implant unfurls its arms under the skull

Posted by in categories: biotech/medical, computing, neuroscience

A soft brain implant that unfurls under the skull could give doctors a less invasive way to monitor patients’ brain activity — and maybe allow people to directly control technology with their minds.

The challenge: Placing an electrode array on the surface of the brain allows scientists to see neural activity in far more detail than is possible with electrodes outside of the skull.

MIT’s Electron Spin Magic Sparks Computing Evolution

Posted by in categories: computing, particle physics

An MIT team precisely controlled an ultrathin magnet at room temperature, which could enable faster, more efficient processors and computer memories.

Experimental computer memories and processors built from magnetic materials use far less energy than traditional silicon-based devices. Two-dimensional magnetic materials, composed of layers that are only a few atoms thick, have incredible properties that could allow magnetic-based devices to achieve unprecedented speed, efficiency, and scalability.

While many hurdles must be overcome until these so-called van der Waals magnetic materials can be integrated into functioning computers, MIT researchers took an important step in this direction by demonstrating precise control of a van der Waals magnet at room temperature.

Intel’s new 6.2GHz CPU is the world’s fastest out-of-the-box

Posted by in category: computing

Intel wants to stay ahead of the performance game in the PC chip market, a throne that it often used to sit on before AMD and Apple’s new chips blew it out of the competition. But now it has again solidified its hold on the desktop performance crown with the release of its new Core i9-14900KS processor.

Launching it as a “special edition” release, the new chip represents a massive jump from last year’s top performer, Intel’s Core i9-13900KS. What is its top clock speed? Well out-of-the-box, it hits a maximum clock speed of 6.2GHz. This makes it the undisputed fastest consumer-grade desktop processor currently available.

Scientists demonstrate how individual differences in ‘whole-brain’ activity are generated in roundworms

Posted by in categories: biological, computing, neuroscience

Joint research led by Yu Toyoshima and Yuichi Iino of the University of Tokyo has demonstrated individual differences in, and successfully extracted commonalities from, the whole-brain activity of roundworms. The researchers also found that computer simulations based on the whole-brain activity of roundworms more accurately reflect real-brain activity when they include so-called “noise,” or probabilistic elements. The findings were published in the journal PLOS Computational Biology.

The Caenorhabditis elegans is a favorite among neuroscientists because its 302 neurons are completely mapped. This gives a fantastic opportunity to reveal their neural mechanism at a systems level. Thus far, scientists have been making progress in revealing the different states and patterns of each neuron and the assemblies they form. However, how these states and patterns are generated has been a less explored frontier.

Pi calculated to 105 trillion digits, smashing world record

Posted by in categories: computing, electronics

The calculation, which took around 75 days to complete, was carried out with 36 of the company’s proprietary solid-state drives (SSDs) — a storage medium fitted into many of the newest laptops — that stored altogether around 1 petabyte (1 million gigabytes) of data.

Processors are also needed to perform the number-crunching — with more powerful components reducing the time it takes to perform the necessary calculations. However, reliable and large-capacity storage is arguably more important because you need to store a massive amount of data in such a process.

The achievement “was no small feat,” Solidigm owner Brian Beeler said in the statement. “It involved meticulous planning, optimization, and execution.”

Can a classical computer tell if a quantum computer is telling the truth?

Posted by in categories: computing, quantum physics

Yes, say researchers who experimentally executed a protocol designed to do just that.
