A first-principles model accounts for the wide range of critical temperatures (T_c’s) for four materials and suggests a parameter that determines T_c in any high-temperature superconductor.

Since the first high-temperature superconducting materials, known as the cuprates, were discovered in 1986, researchers have struggled to explain their properties and to find materials with even higher superconducting transition temperatures (T_c’s). One puzzle has been the cuprates’ wide variation in T_c, ranging from below 10 K to above 130 K. Now Masatoshi Imada of Waseda University in Japan and his colleagues have used first-principles calculations to determine the order parameters—which measure the density of superconducting electrons—for four cuprate materials and have predicted the T_c’s based on those order parameters [1]. The researchers have also found what they believe is the fundamental parameter that determines T_c in a given material, which they hope will lead to the development of higher-temperature superconductors.

For each material, Imada and his colleagues applied the basic principles of quantum mechanics, focusing on the planes of copper and oxygen atoms that are known to host the superconducting electrons. They used a combination of numerical techniques, including one supplemented by machine learning, and did not require any adjustable parameters.

The goal is to improve the speed, accuracy, and accessibility of weather forecasting and other climate applications.

Tesla has been pushing the boundaries of what’s possible in the automotive industry. A recent demonstration of this is the bulletproof testing of the Cybertruck, conducted using Tesla Bots. This article delves into the details of these tests, the implications for Tesla’s technological advancements, and the potential future of these innovations.

In an ironic twist, the Chinese government is turning to Huawei to spearhead the nation’s quest for semiconductor self-reliance.

The sanctions made it so that only those with special permission could produce the chips designed by Huawei. As a result, Huawei faced difficulties in obtaining new chips for the development of more advanced smartphones.

During power outages, microgrids leverage local renewable sources like rooftop solar panels and small wind turbines for efficient power restoration.

Addressing this common challenge, a research team from the University of California — Santa Cruz led by assistant professor Yu Zhang is employing innovative methods to enhance power systems’ efficiency, dependability, and robustness. For this, they have devised an artificial intelligence (AI) centered strategy to intelligently manage microgrids intelligently, ensuring effective power restoration in the event of outages.

America calls and raises the AI bet with the B-21 Raider stealth bomber.

AI with image recognition opens up new possibilities for designers and developers to quickly turn an idea into a prototype. There are several approaches based on OpenAI technology.

The introduction of multimodal capabilities in GPT-4 has laid an important foundation for future software development. Thanks to GPT-4V, the AI model accepts both text and images as input. This allows it to generate working code from screenshots or rudimentary drawings.

Recently, several products have been developed around this idea. The collaborative whiteboard tool tldraw has set up a playground on the website makereal.tldraw.com, where mockups of website elements can be created in the browser. GPT-4V converts these into code using the OpenAI API. A separate API key is required.

Will artificial intelligence serve humanity — or will it spawn a new species of conscious digital beings with their own agenda?

It’s a question that has sparked scores of science-fiction plots, from “Colossus: The Forbin Project” in 1970, to “The Matrix” in 1999, to this year’s big-budget tale about AI vs. humans, “The Creator.”

The same question has also been lurking behind the OpenAI leadership struggle — in which CEO Sam Altman won out over the nonprofit board members who fired him a week earlier.
