Possibilities of the biosimilar principle of learning are shown for a memristor-based neural network
Lobachevsky University scientists together with their colleagues from the National Research Center "Kurchatov Institute" (Moscow) and the National Research Center "Demokritos" (Athens) are working on the hardware implementation of a spiking neural network based on memristors. The key elements of such a network, along with pulsed neurons, are artificial synaptic connections that can change the strength (weight) of connection between neurons during the learning.
Infrared imagery from NASA's Aqua satellite shows that Tropical Storm Barry doesn't look like a typical strong tropical cyclone. Imagery revealed that Barry is elongated and the strongest storms were south of it's stretched out center of circulation.
Warnings and Watches
HOUSTON - (July 12, 2019) - The ever-more-humble carbon nanotube may be just the device to make solar panels - and anything else that loses energy through heat - far more efficient.
Rice University scientists are designing arrays of aligned single-wall carbon nanotubes to channel mid-infrared radiation (aka heat) and greatly raise the efficiency of solar energy systems.
Gururaj Naik and Junichiro Kono of Rice's Brown School of Engineering introduced their technology in ACS Photonics.
Rush University Medical Center researchers have proposed a rating system that standardizes and combines data from five leading hospital rating systems into an easy-to-understand composite score of one to 10 that will help guide consumer's hospitals choice.
Vast rings of electrically charged particles encircle the Earth and other planets. Now, a team of scientists has completed research into waves that travel through this magnetic, electrically charged environment, known as the magnetosphere, deepening understanding of the region and its interaction with our own planet, and opening up new ways to study other planets across the galaxy.
MEDFORD/SOMERVILLE, Mass. (July 12, 2019) --A research collaboration between Tufts University and the Chinese Academy of Sciences has led to the development of a significantly improved delivery mechanism for the CRISPR/Cas9 gene editing method in the liver, according to a study published recently in the journal Advanced Materials. The delivery uses biodegradable synthetic lipid nanoparticles that carry the molecular editing tools into the cell to precisely alter the cells' genetic code with as much as 90 percent efficiency.
PHILADELPHIA (July 12, 2019) - Nurses play a pivotal role in caring for hospitalized patients with social risk factors and preparing them for discharge. Now, a new study from the University of Pennsylvania School of Nursing (Penn Nursing) illustrates how certain health system constraints present barriers to effective care and impact outcomes for patients with high social risks.
Being able to see green spaces from your home is associated with reduced cravings for alcohol, cigarettes and harmful foods, new research has shown.
The study, led by the University of Plymouth, is the first to demonstrate that passive exposure to nearby greenspace is linked to both lower frequencies and strengths of craving.
It builds on previous research suggesting exercising in nature can reduce cravings, by demonstrating the same may be true irrespective of physical activity.
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA)
have made the first-ever observations of a circumplanetary disk, the planet-girding belt of dust and gas that astronomers strongly theorize controls the formation of planets and gives rise to an entire system of moons, like those found around Jupiter.
CLEMSON, South Carolina - Researchers from Clemson University's Environmental Toxicology Program have published research connecting an enzyme associated with detoxification to obesity and fatty liver disease, especially in males.
