The spectral lines of antiprotonic helium atoms are shown to retain their sub-gigahertz linewidth upon submersion in a bath of superfluid helium, enabling the hyperfine structure to be resolved.
Advances in the fields of robotics, autonomous driving and computer vision have increased the need for highly performing sensors that can reliably collect data in different environmental conditions. This includes imagers that can operate at near-infrared wavelengths (i.e., 0.7â1.4 ”m), thus potentially collecting high resolution images in complex or unfavorable atmospheric conditions, such as in the presence of rain, fog and smoke.
Researchers at Huazhong University of Science and Technology (HUST), HiSilicon Optoelectronics Co. Limited, and Optical Valley Laboratory have recently developed a near-infrared colloidal quantum dot (CQD) imager. This highly efficient imager was presented in a paper published in Nature Electronics.
âOur group was founded at Wuhan National Laboratory for Optoelectronics, HUST in 2012 and continuously conducts research on CQD materials and devices with Associate Prof. Jianbing Zhang,â Liang Gao, one of the researchers involved in the study, told TechXplore.
Computer-based animators who are tasked with bringing to life imaginary worlds and characters are aided by simulators that can model the many possible ways an object or fluid might move through a physical space. Known as âsolvers,â these simulators provide a significant head start on the work of animation. But thereâs a catch. As computers have gotten faster, these solvers often create too many options for the animator to effectively sort through looking for just the right one.
âA simulator can return thousands of options. Itâs so time consuming to sort through them that these helpful solvers canât be used to their full potential,â said Purvi Goel, a doctoral candidate in computer science at Stanford, who with her mentor, professor Doug James, has created a new approach to refine the search and narrow results to the most promising options.
They call it âUnified Many-Worlds Browsing,â and they will debut their approach at the upcoming SIGGRAPH 2022 conference in Vancouver, British Columbia, the premier annual gathering for computer graphics and interactive techniques. The approach could both speed the search process for animators and, by limiting the options the simulators must cycle through, reduce compute time and expense. Ultimately, the researchers hope, it will allow artists and scientists to interface with solvers with unparalleled ease and efficiency.
It took researchers about 62 minutes to crack a late-stage Post-Quantum Encryption candidate algorithm using a single-core CPU.
Threat actors are increasingly mimicking legitimate applications like Skype, Adobe Reader, and VLC Player as a means to abuse trust relationships and increase the likelihood of a successful social engineering attack.
Other most impersonated legitimate apps by icon include 7-Zip, TeamViewer, CCleaner, Microsoft Edge, Steam, Zoom, and WhatsApp, an analysis from VirusTotal has revealed.
âOne of the simplest social engineering tricks weâve seen involves making a malware sample seem a legitimate program,â VirusTotal said in a Tuesday report. âThe icon of these programs is a critical feature used to convince victims that these programs are legitimate.â
Artemis I is set to launch August 29 for an uncrewed mission to the Moon. NASA hopes its Artemis program will return humans to the lunar surface.
All commercial and public buildings have been banned from lowering their AC below 81 degrees, despite record shattering heatwaves across Europe.
As most of you know I have cancer called multiple myeloma and have had it for almost a decade now. Unfortunately medical bills are staggering, especially in the US. I am asking to reach a goal of $10,000 to help wipe out if not most of my medical debt and expenses. I have over 1,000 friends on Facebook. If each friend donated $8.00 this would help me not only reach but exceed my goal. Please consider helping:
If anyone needs proof of my diagnosis or medical debt please message me.
I have outlined my journey with cancer several years ago on Lifeboat Foundationâs blog: https://lifeboat.com/blog/2018/09/83169
Hi, my name is Nicholas and I was diagnosed with multiple myeloma several years ago. Medical bills are exceedingly expensive even with insurance. I am creating content on tiktok in hopes to create an income to help me cover such costs.
How expensive is it to make a panel that uses e-ink technology? That might depend on how flexible you are. [RBarron] read about reverse engineering point-of-sale shelf labels and found them on eBay for just over a buck apiece. Next thing you know, 20 of them were working together in a single panel.
The panels use RF or NFC programming, normally, but have the capability to use BLE. Naturally you could just address each one in turn, but that isnât very efficient. The approach here is to use one label as a BLE controller and it then drives the other displays in a serial daisy chain, where each labelâs receive pin is set to the previous labelâs transmit pin.
