COLLEGE PARK, Md. - To get more participants in online auctions and drive up the winning bid prices, two things matter: how long an auction is active and the day of the week it closes, finds researchers from the University Maryland, Stanford University, University of Pennsylvania and Indiana University.
Forthcoming as "Managing Market Thickness in Online B2B Markets" in Management Science, the study focuses on online business-to-business (B2B) auction platforms used by retailers to sell their unsold or returned inventory to discount stores and wholesale liquidators.
Most people are familiar with turbulence in aviation: certain wind conditions cause a bumpy passenger flight. But even within human blood vessels, blood flow can be turbulent. Turbulence can appear when blood flows along vessel bends or edges, causing an abrupt change in flow velocity. Turbulent blood flow generates extra forces which increase the odds of blood clots to form. These clots grow slowly until they may be carried along by the bloodstream and cause stroke by blocking an artery in the brain.
Mechanical heart valves produce turbulent blood flows
Binge drinking by teenagers in their senior year of high school is a strong predictor of dangerous behaviors later in life, including driving while impaired (DWI) and riding with an impaired driver (RWI), according to a new Yale-led study.
But researchers also found that what teens believe their parents know about their leisure activities and who their friends are -- and whether the parents approve or disapprove of alcohol use -- can have life-saving effects.
DES PLAINES, IL -- Prolonged cardiac rhythm monitoring will improve arrhythmia diagnostic yield among non-low-risk emergency department patients with syncope. That is the finding of a study published in the January 2020 issue of Academic Emergency Medicine (AEM), a journal of the Society for Academic Emergency Medicine (SAEM).
The lead author of the study is Monica Solbiati MD, PhD, Department of Clinical and Community Sciences, University of Milan, Milan, Italy.
In a circular economy, the city waste being turned into resources, is of great importance considering more than 70% of the inhabitants in Europe live in urban areas and produce a great amount of biowaste coming from the treatment of their waste waters. The European project RES URBIS (Resources from Urban Bio-waste), showed that different biowaste produced in an urban environment can be treated within the same chain of valorisation and can obtain products with biological origins, such as bioplastic, with a higher economic value to the classic compost and biogas.
If not identified before surgery, a rare genetic mutation could result in your dog being exposed to dangerously high levels of anesthetic agents.
Scientists at Washington State University's College of Veterinary Medicine initially discovered the mutation in greyhounds and more recently in other common dog breeds.
The research group, a member of the Program in Individualized Medicine (PrIMe), published its findings last week in Scientific Reports.
NEW YORK (January 13, 2020) - A new study says that the planet's wildlife is increasingly under the boot of humanity.
Using the most comprehensive dataset on the "human footprint," which maps the accumulated impact of human activities on the land's surface, researchers from WCS, University of Queensland, and other groups found intense human pressures across the range of a staggering 20,529 terrestrial vertebrate species.
Extreme heat kills more people in the United States than any other type of hazardous weather and will likely become even deadlier due to climate change. However, extreme heat does not affect all people equally. Surface temperatures in different neighborhoods within a single city can vary by a whopping 20 degrees (F), making some people more at risk of experiencing dangerous temperatures.
Climate is an important factor in determining a plant species' growing zone. Some studies suggest that by the turn of the next century, climate change will have caused some species to spread several dozen kilometres north of their current distribution areas.
Such changes could have major consequences on how land-based ecosystems function.
New research from the University of California San Diego finds that solar geoengineering--the intentional reflection of sunlight away from the Earth's surface--may reduce income inequality between countries.
Researchers at San Diego State University have found a new way to harness food as medicine, which has far reaching implications to control harmful microbes in our gut while balancing microbial diversity by fostering the growth of beneficial bacteria.
Foods we eat commonly affect our gut microbiota. New research shows they do so by triggering the production of bacteriophage - viruses that infect and replicate inside bacteria. Compounds in these foods have an antimicrobial effect which causes the phage to replicate.
Whether it be a brisk walk around the park or high intensity training at the gym, exercise does a body good. But what if you could harness the benefits of a good workout without ever moving a muscle?
Michigan Medicine researchers studying a class of naturally occurring protein called Sestrin have found that it can mimic many of exercise's effects in flies and mice. The findings could eventually help scientists combat muscle wasting due to aging and other causes.
Every language has cases in which two or more concepts are expressed by the same word, such as the English word fly, which refers to both the act of flying and to the insect. By comparing patterns in these cases, which linguists call colexifications, across languages, researchers can gain insights into a wide range of issues, including human perception, language evolution, and language contact.
Researchers at the University of South Florida (USF) have discovered a novel feedback pathway from the brain to the eye that modulates eye pressure – a significant advancement in the effort to diagnose and treat glaucoma. Glaucoma is associated with increased pressure in the eye due to a reduce ability of the eye to maintain proper fluid drainage. The heightened pressure applies mechanical strain to the optic nerve as the nerve exits the eye, resulting in vision loss and potential blindness.
Members of collective leadership groups can maintain cohesion and act decisively when faced with a crisis, in spite of lacking the formal authority to do so, according to new research from Cass Business School.
