Exploring people's perception of geometric features, personalities and emotions in videos with virtual humans

Researchers at Pontifical Catholic University of Rio Grande do Sul have recently carried out a study aimed at evaluating people's perceptions of geometric features, personalities and emotions presented in video sequences with virtual humans. Their study, outlined in a paper pre-published on arXiv, merges computer science tools with psychology research practices.

Can sound protect eagles from wind turbine collisions?

Every year, bald and golden eagles are killed when they inadvertently fly into wind turbine blades. One possible way to prevent these deaths is to chase the birds away with acoustic signals—sound. To determine what types of sounds are most effective in deterring the birds, researchers at the University of Minnesota and their colleagues tested the behavioral responses of bald eagles to a battery of both natural and synthetic acoustic stimuli.

Excitonic radiative decay faster than thermal dephasing in ZnO thin films

A team of researchers from Osaka University, Osaka Prefecture University, Osaka City University, and The University of Shiga Prefecture have found excitonic radiative decay faster than thermal dephasing at room temperature in zinc oxide (ZnO) thin films. These results, published recently in Physical Review Letters, will greatly reduce the thermal energy loss in optical operations.

Coherent? Voice disorders significantly affect listeners, too

"Fly heading two three zero, runway two seven left, cleared for takeoff." Air traffic controllers are among the 25 to 45 percent of the workforce in the United States who use their voices professionally. It is imperative for their listeners to understand what they are communicating. Air traffic controllers, teachers and university professors have a high prevalence of voice disorders referred to as "dysphonia." Other professions also are at risk including clergy, attorneys, counselors and performers.

Researchers map symbiotic relationships between trees and microbes worldwide

In and around the tangled roots of the forest floor, fungi and bacteria grow with trees, exchanging nutrients for carbon in a vast, global marketplace. A new effort to map the most abundant of these symbiotic relationships—involving more than 1.1 million forest sites and 28,000 tree species—has revealed factors that determine where different types of symbionts will flourish. The work could help scientists understand how symbiotic partnerships structure the world's forests and how they could be affected by a warming climate.

Machine learning reduces language barriers in global trade, research shows

Machine learning and artificial intelligence have exploded onto the scene in recent years, offering the hope of greater business efficiency. At the same time, researchers have found virtually no empirical evidence supporting the promised strides in labor productivity and economic activity.

Framework improves 'continual learning' for artificial intelligence

Researchers have developed a new framework for deep neural networks that allows artificial intelligence (AI) systems to better learn new tasks while "forgetting" less of what it has learned regarding previous tasks. The researchers have also demonstrated that using the framework to learn a new task can make the AI better at performing previous tasks, a phenomenon called backward transfer.

Stop gambling with black box and explainable models on high-stakes decisions

As the buzzwords "machine learning" continue to grow in popularity, more industries are turning to computer algorithms to answer important questions, including high-stakes fields such as healthcare, finance and criminal justice. While this trend can lead to major improvements in these realms, it can also lead to major problems when the machine learning algorithm is a so-called "black box."

Researchers pinpoint why lymphoma patients may become resistant to specific therapy

With more targeted therapies being approved each year for cancer, the development of drug resistance to these agents is a growing concern. It has often been assumed that drug resistance is due to the presence or development of additional genetic alterations; however, it is now clear that resistance mechanisms are more complicated. Researchers from Moffitt Cancer Center and Dana-Farber Cancer Institute have discovered a mechanism of drug resistance to Venetoclax, also known as ABT-199, a BCL-2 targeting drug commonly used to treat chronic lymphocytic leukemia and acute myeloid leukemia. Their findings, published in the journal Cancer Cell, also suggest a possible co-treatment strategy to overcome this resistance.

The conspicuous absence of women in India's labour force

India's rapid economic growth has been accompanied by falling fertility rates and higher educational attainment among women. These advances often lead to an increase in women entering the labour force, but there has been a surprising decline on this front in India. Less than 30% of working-age women are currently in work compared to nearly 80% of men in India.

Just like toothpaste: Fluoride radically improves the stability of perovskite solar cells

Solar cells made of perovskite hold much promise for the future of solar energy. The material is cheap, easy to produce and almost as efficient as silicon, the material traditionally used in solar cells. However, perovskite degrades quickly, severely limiting its efficiency and stability over time. Researchers from Eindhoven University of Technology, energy research institute DIFFER, Peking University and University of Twente have discovered that adding a small amount of fluoride to the perovskite leaves a protective layer, increasing stability of the materials and the solar cells significantly. The solar cells retain 90 percent of their efficiency after 1000 hours operation at various extreme testing conditions. The findings are published today in the leading scientific journal Nature Energy.
