Advancing the well-being of animals, people and the planet — aaron schacht — executive vice president, innovation, regulatory & business development, elanco.
Aaron Schacht is Executive Vice President: Innovation, Regulatory + Business Development at Elanco (https://www.elanco.com/), an American pharmaceutical company which produces medicines and vaccinations for pets and livestock, and which until 2,019 was a subsidiary of Eli Lilly and Company.
Researchers from the National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki, Ph.D.), Network Research Institute, succeeded the first S, C and L-bands transmission over long-haul distances in a 4-core optical fiber with standard outer diameter (0.125 mm). The researchers, lead by Benjamin J. Puttnam, constructed a transmission system that makes full use of wavelength division multiplexing technology by combining different amplifier technologies, to achieve a transmission demonstration with date-rate of 319 terabits per second, over a distance of 3,001 km. Using a common comparison metric of optical fiber transmission the data-rate and distance produce of 957 petabits per second x km, is a world record for optical fibers with standard outer diameter.
In this demonstration, in addition to the C and L-bands, typically used for high-data-rate, long-haul transmission, we utilize the transmission bandwidth of the S-band, which has not yet been used for further than single span transmission. The combined 120nm transmission bandwidth allowed 552 wavelength-division multiplexed channels by adopting 2 kinds of doped-fiber amplifier together with distributed Raman amplification, to enable recirculating transmission of the wideband signal. The standard cladding diameter, 4-core optical fiber can be cabled with existing equipment, and it is hoped that such fibers can enable practical high data-rate transmission in the near-term, contributing to the realization of the backbone communications system, necessary for the spread of new communication services Beyond 5G.
The universe is (nearly) 14 billion years old, astronomers confirm.
With looming discrepancies about the true age of the universe, scientists have taken a fresh look at the observable (expanding) universe and have estimated that it is 13.77 billion years old (plus or minus 40 million years).
Between August2020and July 2,021 the rainforest lost 10.476 square kilometers – an area nearly seven times bigger than greater London and 13 times the size of New York City, according to data released by Imazon, a Brazilian research institute that has been tracking the Amazon deforestation since 2008. The figure is 57% higher than in the previous year and is the worst since 2012.
Sharp wave-ripples from the hippocampus are shown to modulate peripheral glucose homeostasis in rats, offering insights into the mechanism that links sleep disruption and blood glucose regulation in type 2 diabetes.
Program aims to provide physical systems with ability to adapt to unexpected events in real-time and effectively communicate system changes to human and AI operators.
Many complex, cyber-physical military systems are designed to last for decades but their expected functionality and capabilities will likely evolve over time, prompting a need for modifications and adaptation. High Mobility Multipurpose Wheeled Vehicles (HMMWV), for example, had a design life of 15 years, but are now undergoing modernization to extend the average age of the fleet to 37+ years. At design time, these systems are built to handle a range of expected operating environments and parameters. Adapting them is currently done in an improvisational manner – often involving custom-tailored aftermarket remedies, which are not always commonly available, require a skilled technician to install, and can take months or even years to procure. Further, as they evolve and are placed outside of their original design envelop these systems can fail unexpectedly or become unintentionally dangerous.
“Today, we start with exquisitely built control systems but then someone needs to add something or make a modification – all of which results in changes to the safe operating limits,” said DARPA program manager John-Francis Mergen. “These changes are done in a way that wasn’t anticipated – or more likely couldn’t have been anticipated – by the original designers. Knowing that military systems will undoubtedly need to be altered, we need greater adaptability.”
FENCE program selects researchers to develop low-power, low-latency neuromorphic camera technologies to enable future military applications.
DARPA today announced that three teams of researchers led by Raytheon, BAE Systems, and Northrop Grumman have been selected to develop event-based infrared (IR) camera technologies under the Fast Event-based Neuromorphic Camera and Electronics (FENCE) program. Event-based – or neuromorphic – cameras are an emerging class of sensors with demonstrated advantages relative to traditional imagers. These advanced models operate asynchronously and only transmit information about pixels that have changed. This means they produce significantly less data and operate with much lower latency and power.
“Neuromorphic refers to silicon circuits that mimic brain operation; they offer sparse output, low latency, and high energy efficiency,” said Dr. Whitney Mason, the program manager leading the FENCE program. “Event-based cameras operate under these same principles when dealing with sparse scenes, but currently lack advanced ‘intelligence’ to perform more difficult perception and control tasks.”
Deploying two unrelated CRISPR nucleases in tandem, with multiplexed CRISPR RNAs and a chemically stabilized activator, creates a simple, one-step assay that can rapidly detect attomolar concentrations of RNA without needing target amplification.
