Sensors, Vol. 19, Pages 4820: A Single-Shot Non-Line-of-Sight Range-Finder Sensors doi: 10.3390/s19214820 Authors: James Brooks Daniele Faccio The ability to locate a target around a corner is crucial in situations where it is impractical or unsafe to physically move around the obstruction. However, current techniques are limited to long acquisition times as they rely on single-photon counting for precise arrival time measurements. Here, we demonstrate a single-shot non-line-of-sight range-finding method operating at 10 Hz and capable of detecting a moving human target up to distances of 3 m around a corner. Due to the potential data acquisition speeds, this technique will find applications in search and rescue and autonomous vehicles.

Publication date: Available online 11 December 2019Source: Journal of Alloys and CompoundsAuthor(s): Yanxia Zhang, Man Yang, Xin Jiang, Wei Lu, Yan XingAbstractDesign and synthesis of three-dimension (3D) nanowire arrays (NWAs) electrocatalyst with a core-shell structure have been considered as an efficient way to enhance the performances for the oxygen evolution reaction (OER). In this work, novel hierarchical CoFe-LDH/NiCo2O4/Ni foam (CoFe-LDH/NCO/NF) core-shell nanowire arrays have been fabricated via a facile two-step strategy. The as-obtained nanocomposites were characterized by multiple methods, and their electrocata...

Diego ZuluagaYesterday, Joe Nocera penned an extraordinarycolumn expressing his bafflement at the Trump administration ’sdrive to release Fannie Mae and Freddie Mac, two firms that purchase and guarantee around half of single-family mortgages in the United States, from government conservatorship. Nocera argues against such a move, writing that “if it ain’t broke, don’t fix it . . . Fannie Mae and Freddie Mac ain’t broke.”The piece is disconcerting from start to finish. Nocera writes that Fannie and Freddie make the 30-year fixed-rate mortgage, a product common only in the U.S., possible ...

By SAURABH JHA, MD Slumdog TB No one knows who gave Rahul Roy tuberculosis. Roy’s charmed life as a successful trader involved traveling in his Mercedes C class between his apartment on the plush Nepean Sea Road in South Mumbai and offices in Bombay Stock Exchange. He cared little for Mumbai’s weather. He seldom rolled down his car windows – his ambient atmosphere, optimized for his comfort, rarely changed. Historically TB, or “consumption” as it was known, was a Bohemian malady; the chronic suffering produced a rhapsody which produced fine art. TB was fashionable in Victorian Britain...

(University of Maryland) New research reveals how a week in the dark rewires brain cell networks and changes hearing sensitivity in adult mice long after the optimal window for auditory learning has passed. With further study, cross-modal learning -- the manipulation of one sense to induce change in another sense -- could be used to help people with disabilities. For example, temporary sight deprivation might be used to help deaf and hearing-impaired people adapt to cochlear implants and hearing aids.

Eyes are a worry aren’t they? I use mine a lot…but I have all these little floater things bobbing about, I see them when I use my PC, when I’m on the phone, when I’m outside on a sunny day, sitting reading, watching TV, playing guitar, taking photos, singing. All the time, actually. They’re always there. I was getting worried. Couple that to the need to find my glasses to read anything at all or look at an object any smaller than an inch across, and it’s all a bit worrying. So, nice to have an eye test where nothing truly untoward is revealed, just a slight and inevitably sliding into ...

By Pape Amadou Gaye, President and Chief Executive OfficerNovember 27, 2019Just 20 years ago, we could hardly imagine an AIDS-free generation. And the idea that poor countries would no longer rely on foreign aid to care for their people was inconceivable.But today, I believe both are in sight.The entire field of global health and development is shifting. Major funders, such as the U.S. government, are pushing ahead with an approach called localization, wherein countries manage their own foreign aid, mobilize their own public and private revenues, and eventually become self-reliant.This is what so many of us in nongo...

The sun is streaming through the curtains of a room that you have never seen before. You squint and rub your bloodshot eyes, as your hand reaches out to feel the prone body of the snoring person who a few hours earlier was a stranger. You notice your own naked body and wonder how the two of you spent the interceding time. You look at the floor next to the bed and see your clothes, strewn across the carpet, wine bottles and glasses, a few joints, and a line of cocaine on the dresser across the room. You slide out of bed, gather your belongings, hightail it to the bathroom and quickly get yourself street ready. Wondering ho...

I tried to kill my father for years. To be fair, I was following his wishes. He’d made it clear that when he no longer recognized me, when he could no longer talk, when the nurses started treating him like a toddler, he didn’t want to live any longer. My father was 58 years old when he was diagnosed with Alzheimer’s disease. He took the diagnosis with the self-deprecating humor he’d spent a lifetime cultivating, constantly cracking jokes about how he would one day turn into a zombie, a walking corpse. We had a good 10 years with him after the diagnosis. Eventually, his jokes came true. Seven years ...
