A teenaged Muslim boy from Lucknow who was allegedly beaten up by policemen while he was trying to buy food has succumbed.
The slain has been identified as Mohammad Rizwan, he has become the first fatality from purported police high-handedness in enforcing the lockdown in Uttar Pradesh.
Rizwan’s father, Mohammed Israil, said his son had felt very hungry on Thursday night.
Scientists found that a class of particles known as bosons can behave as an opposite class of particles called fermions, when forced into a line.
The research, conducted at Penn State University and funded in part by the Army Research Office, an element of U.S. Army Combat Capabilities Development Command’s Army Research Laboratory, found that when the internal interactions among bosons in a one-dimensional gas are very strong, their velocity distribution transforms into that of a gas of non-interacting fermions when they expand in one dimension. The research is published in the journal Science.
“The performance of atomic clocks, quantum computers and quantum systems rely upon the proper curation of the properties of the chosen system,” said Dr. Paul Baker, program manager, atomic and molecular physics at ARO. “This research effort demonstrates that the system statistics can be altered by properly constraining the dimensions of the system. In addition to furthering our understanding of foundational principles, this discovery could provide a method for dynamically switching a system from bosonic to fermionic to best meet the military need.”
Here’s another neat thing drones can do—beam power across the sky to recharge sensors in hard-to-reach places.
Remote sensors play a valuable role in collecting data—but recharging these devices while they are scattered over vast and isolated areas can be tedious. A new system is designed to make the charging process easier by using unmanned aerial vehicles (UAVs) to deliver power using radio waves during a flyby. A specialized antenna on the sensor harvests the signals and converts them into electricity. The design is described in a study published 23 March in IEEE Sensors Letters.
Joseph Costantine and his colleagues at the American University of Beirut, in partnership with researchers at the Institute of Electronics, Computer, and Telecommunications Engineering in Italy, were exploring ways to remotely charge sensors using radio frequency waves (the same form of energy used to transmit Wi-Fi). However, a major challenge was that the source of the radio waves must be fairly close to the sensor in order to sufficiently charge it.
New numbers from the digital asset management giant Grayscale show investors are collectively throwing big money into Ethereum for the first time, on top of record investment numbers for Bitcoin.
According to Grayscale’s Q1 2020 report, institutions are taking a serious interest in ETH, enough to print a record quarterly inflow into the Grayscale Ethereum Trust.
Spencer Noon, the head of crypto investments at DTC Capital, says the numbers show Ethereum has reached a turning point with high-net worth investors.
In this video, we’ll be discussing 5G – more specifically, what it is and its ability to change our world! 5G is a core technology in establishing the digital infrastructure of the future and will be essential in how all of the over 50 billion mobile and connected devices by 2020 will communicate together!
[0:25–2:55] First we’ll take a quick look at the history of mobile networks, and how they have evolved over the years to present day.
[2:55–14:20] Following that, we’ll focus on the technologies a 5G network is composed of and the improvements in speed, latency, bandwidth and energy consumption they will bring.
[14:20–23:40] Finally, we’ll discuss the transition process from 4G LTE networks to 5G as well as the timeframe for the release of 5G to the public.
More and more, people don’t care about expert views. That’s according to Tom Nichols, author of “The Death of Expertise,” who says Americans have become insufferable know-it-alls, locked in constant conflict and debate with others over topics they actually know almost nothing about. Nichols shares his humble opinion on how we got here.
The airspace above future battlefields is expected to be increasingly congested with large numbers of unmanned aerial systems, manned aircraft, munitions and missiles filling the skies. To de-conflict airspace activities of friendly forces and rapidly counter an enemy’s actions on the battlefield requires new technologies to effectively integrate effects from all domains.
Video Friday is your weekly selection of awesome robotics videos, collected by your Automaton bloggers. We’ll also be posting a weekly calendar of upcoming robotics events for the next few months; here’s what we have so far (send us your events!):
Let us know if you have suggestions for next week, and enjoy today’s videos.
In 2017, a team of USC Viterbi researchers created ADAMMS (Agile Dexterous Autonomous Mobile Manipulation System), a robot designed to support repetitive human tasks, like transporting equipment or tending a 3D printer at 3 a.m. ADAMMS can perform specific actions like opening doors or picking up objects autonomously. These researchers, including postdoctoral researcher in the USC Viterbi Department of Aerospace and Mechanical Engineering Pradeep Rajendran, AME Ph.D student Shantanu Thakar, Department of Computer Science master’s student Hyojeong Kim and M.S. AME’18 Vivek Annem, envisioned a tool that could support humans remotely.
