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 […]
Gallium nitride (GaN) semiconductors have come a long way since first becoming commercially viable as highly bright, blue light-emitting diodes (LEDs) in the early 1990s and, subsequently, a core technology for Blu-ray optical disk players. It would be almost two decades before the technology was commercially viable for field effect transistors (FETs) with high power […]
“Research progress on p-type amorphous semiconductors has been notably sluggish,” according to the Pohang University of Science and Technology (PosTech). “Despite the widespread adoption of n-type amorphous oxide semiconductors, particularly those based on IGZO [indium gallium zinc oxide] in OLED displays and memory devices, the advancement of p-type oxide materials has been impeded by numerous […]
Resolution is as fine as individual telegraph poles. “This technology allows for accurate disaster prediction by building a model that learns disaster patterns from facility data that the NTT Group has inspected and repaired [after] past disasters,” according to the company. “In addition, it can be predicted from publicly available data throughout Japan, making it […]
Zhongzhi Chip is said to be collaborating with the AI chip startup Tenstorrent and other “stellar global RISC-V chip companies” and to be looking for other alliances. It is said to have considerable financial backing. When Wu was sacked, a number of Arm China staff left including the head of R&D, a regional head […]
