Genetic autopsies to unravel the mystery of sudden deaths

genetic-autopsies-to-unravel-the-mystery-of-sudden-deaths

There are deaths without apparent explanation. They are not violent, nor have they been accompanied by previous symptoms that explain them, and not even the traditional anatomical post-mortem examination can find clues to the cause. They are simply sudden deaths that, in the majority of cases (about 70%), are due to a more or less […]

Sorry Appin, We’re Not Taking Down Our Article About Your Attempts to Silence

from the we-stand-by-our-reporting dept Back in December, we wrote about Appin. We were not writing about the reports (of which there have been many) that the organization that started as a sort of cybersecurity training school, but morphed into a kind of “hack-for-hire” scheme was involved in all sorts of nefarious activity. Rather we wrote […]

A startup allegedly ‘hacked the world’, then came censorship, and now backlash

Hacker-for-hire firms like NSO Group and Hacking Team have become notorious for enabling their customers to spy on vulnerable members of civil society. But as far back as a decade ago in India, a startup called Appin Technology and its subsidiaries allegedly played a similar cyber-mercenary role while attracting far less attention. Over the past […]

7 min read Behold, the electronic sackbut. DON KENNEDY/NATIONAL MUSIC CENTRE If you, like me, think of musical synthesizers as an artifact of 1970s rock and disco, then you, like me, will be surprised to learn that the first electronic synthesizer predates those genres by several decades In 1945, Hugh Le Caine, a physicist at […]

240-Gbit/s sub-THz wireless communications using ultra-low phase noise receiver

Abstract We present a sub-terahertz (THz) wireless link using photonics-based ultra-low phase noise transmitter and receiver. The maximum data rate achieved below hard-decision forward error correction (HD-FEC) threshold by using on-line signal processing was 240 Gbit/s with 64 quadrature amplitude modulation (64QAM) at a single carrier frequency of 275 GHz. We also demonstrate successful 20-m […]

SI Units for Request Rate

Request rate is the number of requests that arrive, or are serviced, or leave, during some period. It’s surprisingly common for people to speak of a request rate without specifying what the length of the period is. I have even seen dashboards that don’t have a fixed period for the metrics query – the request […]
