Deep learning applied for image/video processing opened the door for the practical deployment for object detection and identification with acceptable accuracy. Crowd counting is another application of image/video processing. The scientists at Japan Advanced Institute of Science and Technology (JAIST) designed a new DNN with backward connection, which achieved more accurate estimation of the density of objects. It can be applied for estimating human density in the public or vehicle density on a road in order for improving public safety/security and traffic efficiency.
Researchers at Linköping University's Department of Thematic Studies, Environmental Change, have developed a simple logger for greenhouse gas flows. It is built using inexpensive and easily available parts, and provides data on levels of methane, carbon dioxide, temperature and humidity.
Infertility affects between 10 and 15% of all couples of reproductive ages and can be caused by a wide variety of factors: genetic, physiological, environmental and nutritional.Although there is increasing scientific evidence about the role of nutrition in sperm quality, there is still controversy about the role of overweight, obesity and low weight in sperm parameters.
Cicadas infected with the parasitic fungus Massospora unknowingly engage in trickery with their fellow insects, resulting in effective disease transmission, according to West Virginia University-led research.
Massospora manipulates male cicadas into flicking their wings like females – a mating invitation – which tempts unsuspecting male cicadas and infects them.
Naturally occurring lithium in public drinking water may have an anti-suicidal effect - according to a new study from Brighton and Sussex Medical School (BSMS) and the Institute of Psychiatry, Psychology & Neuroscience at King's College London.
Published in the British Journal of Psychiatry, the study collated research from around the world and found that geographical areas with relatively high levels or concentration of lithium in public drinking water had correspondingly lower suicide rates.
The simplicity and elegance of origami, an ancient Japanese art form, has motivated researchers to explore its application in the world of materials.
RESEARCH TRIANGLE PARK, N.C. -- An Army-funded project developed a self-healing material patterned after squid ring teeth protein. The biodegradable biosynthetic polymer could be used to repair materials that are under continual repetitive movement such as robotic machines, prosthetic legs, ventilators and personal protective equipment like hazmat suits.
AUSTIN, Texas -- Scientists have long been concerned that the common practice of medical journals accepting commercial payments from pharmaceutical companies may lead to pro-industry bias in published articles. According to new research at The University of Texas at Austin, scientists were right to be concerned, but they were focusing on the wrong type of payments.
When NASA’s Perseverance rover lands on Mars next year, it will be equipped with some of the most precise maps of Mars ever created, courtesy of the USGS Astrogeology Science Center. Not only are the new maps essential for a safe landing on Mars, but they also serve as the foundation upon which the science activities planned for the Mars mission will be built.
New York, NY--July 27, 2020--Additive manufacturing--or 3D printing--uses digital manufacturing processes to fabricate components that are light, strong, and require no special tooling to produce. Over the past decade, the field has experienced staggering growth, at a rate of more than 20% per year, printing pieces that range from aircraft components and car parts to medical and dental implants out of metals and engineering polymers.
X-ray experiments at Lawrence Berkeley National Laboratory (Berkeley Lab) played a key role in resolving the origin of rare, odd meteorites that have puzzled scientists since their discovery a half-century ago. Known as type IIE iron meteorites, they appear to have originated from a parent body that had a composition featuring both fully melted and unmelted parts - other meteorite types display only one composition.
Listeria contaminations can send food processing facilities into full crisis mode with mass product recalls, federal warnings and even hospitalization or death for people who consume the contaminated products. Destroying the bacterium and stopping its spread can be challenging because of the formation of biofilms, or communities of resistant bacteria that adhere to drains or other surfaces.
NASA's Aqua satellite provided infrared data on Tropical Depression Hanna while imagery from NASA-NOAA's Suomi NPP satellite was used to create an animation showing its movement from Texas to Mexico. Infrared data can reveal the location of powerful storms that generate heavy rainfall and Hanna drenched Texas upon landfall over the weekend of July 25-26.
Tracking Hanna's Path to Mexico
Got milk? Most people have seen the famous ads featuring celebrities that highlight the importance of drinking milk for building strong bones. Research shows that milk has other benefits, especially for babies, such as helping them grow and strengthening their immune systems. But scientists still don't understand exactly how milk does these things.
A research group led by Prof. CHEN Tao and Prof. ZHU Changfei, and their collaborator Prof. HAO Xiaojing at UNSW, developed a hydrothermal deposition method for the synthesis of antimony selenosulfide for solar cell applications. With this absorber material, the solar cell break the 10% benchmark efficiency barrier. This result has been published in Nature Energy entitled "Hydrothermal deposition of antimony selenosulfide thin films enables solar cells with 10% efficiency".
