A new US law requires TikTok to sever all ties with its Chinese parent ByteDance or face a ban in the United States. Chinese tech giant ByteDance has said it has no plans to sell TikTok after a new US law put it on a deadline to divest from the hugely popular video platform or […]
The overnight success of OpenAI’s ChatGPT thrust generative AI as Silicon Valley’s latest tech revolution, lifting Microsoft, OpenAI’s main backer, to become the world’s most valuable company. Microsoft, the tech titan most closely associated with AI, has announced nearly $10 billion in investments in artificial intelligence abroad in recent months, the price it is willing […]
Google and Alphabet Inc. CEO Sundar Pichai says the company is well positioned for the artificial intelligence era with the technology woven into its platform and services. Google’s parent Alphabet on Thursday trounced revenue and profit expectations for the first quarter of this year, causing shares to leap more than 12 percent. Alphabet reported profit […]
It achieves resolution better than 40cm from 2.1km altitude using around two photons per pixel, in the face of 10,000 daylight noise photons per pixel. Created by the University of Science and Technology of China, the lidar combines three 150mA 1.55μm lasers shining 1ns pulses onto the ground through their own telescopes. Reflections are directed […]
Image source: Ambiq Key Takeaways about Battery Powered AI devices: Battery-powered devices are adopting artificial intelligence (AI) for improved performance. AI devices operating at the edge must be power-stingy. Devices that exploit this trend will come with varied subsystems and capabilities, but all must include comprehensive security features. As technology progresses, the imperative to integrate AI into battery-powered […]
Josephson junctions incorporating domain walls in minimally twisted bilayers. Credit: Julien Barrier et al In a significant development in the field of superconductivity, researchers at The University of Manchester have successfully achieved robust superconductivity in high magnetic fields using a newly created one-dimensional (1D) system. This breakthrough offers a promising pathway to achieving superconductivity in […]
Transform-limited photon emission and high temperature operation make PbV centers suitable building blocks for scalable quantum networks. Credit: Tokyo Tech Much like how electric circuits use components to control electronic signals, quantum networks rely on special components and nodes to transfer quantum information between different points, forming the foundation for building quantum systems. In the […]
Hyperspectral imaging is the most comprehensive of the three common image processing technologies. The other two technologies are red-green-blue (RGB) imaging and multispectral imaging. All three are noninvasive and nondestructive and give engineers and scientists different ways to analyze objects. RGB imaging can be quick and inexpensive to implement and provides basic information about an […]
