Group Activity Recognition (GAR), which aims to identify activities performed collectively in videos, has gained significant attention recently. Existing GAR datasets typically annotate only a single Group Activity (GA) instance per sample, carefully selected from original videos. This approach, while precise, diverges significantly from real-world contexts, which often involve multiple GA instances. Moreover, single word-level annotations are insufficient to encapsulate the complex semantic information in GA, thereby constraining the expansion and ...

MIAMI, FLORIDA (EMBARGOED UNTIL JAN. 9, 2025 AT 6:30 P.M. EST) – Even though lung and related cancer deaths decreased in the world’s 10 most populous countries from 1990 to 2019, these positive statistics do not address trends in mortality linked to tobacco use, air pollution and asbestos exposure. Those areas need ongoing policy measures and research to further reduce deaths, according to a new study from researchers at Sylvester Comprehensive Cancer Center, part of the University of Miami Miller School of Medicine, and collaborating organizations. Their study, published in eClinicalMedicine, ...

A series of more than 100 small earthquakes in Surrey in 2018 and 2019 might have been triggered by oil extraction from a nearby well, suggests a new study by UCL researchers. The earthquakes, which occurred in Newdigate and surrounding areas from April 2018 until early 2019, were recorded as being between 1.34 and 3.18 magnitude, and were linked to cracks in walls and ceilings and other damage to people’s homes, with reports of houses and beds shaking. Geologists have been divided over whether these earthquakes could have been triggered by extraction at the Horse Hill well in Horley about 5km ...

Key takeaways Both intuition and past research suggest that whether people deem someone trustworthy depends on that person’s past behavior and reputation for betrayal. In a series of experiments, psychologists found that subjects regarded those who previously exhibited that behavior as less trustworthy. However, when the betrayal benefited them or had no effect on them, participants regarded the betrayer as trustworthy.  This pattern was largely consistent across the types of relationships studied: friendships, romantic relationships and professional relationships. Imagine this scenario: Two people cheat on their partners with each other ...

UNIVERSITY PARK, Pa. — Antibiotic-resistant Salmonella is a serious public health concern that has increased in recent years as the bacteria have developed ways to survive drugs. According to the U.S. Centers for Disease Control and Prevention, people can get Salmonella from eating contaminated food products or from infected people or animals — typically via unintentional contact with feces via touching hands or stroking a pet. However, a team of Penn State researchers have found that household dogs are an overlooked transmission point for zoonotic pathogens such as nontyphoidal Salmonella, which can cause diarrhea, fever and abdominal cramps, with some ...

For decades, catalysts have been unsung heroes in daily life. These workhorses transform a starting material into a product or fuel with lower energy, like the yeast in bread making and human-made catalysts for converting raw materials into fuels more efficiently and sustainably. A promising class of these helpful substances, called single atom catalysts, has emerged, and researchers need new methods to better understand them. More specifically, they want to know how the structure of the sites where chemical reactions occur, called active sites, affects the catalyst’s ability to speed up the chemical reaction rate, known as the activity.  In an important step forward, researchers ...

CHAMPAIGN, Ill. — While physical neglect is understudied compared to physical, sexual or emotional abuse, neglect is just as damaging to children’s social development, a new study indicates. More than 9,150 individuals, nearly 41% of whom retrospectively reported some form of maltreatment before age 12 or reaching the sixth grade, were included in the study, published in the journal Child Abuse and Neglect. The project explored the impact of abuse or neglect on three dimensions of children’s structural peer relationships — whether maltreated youth were less social/more withdrawn, less popular with or avoided by their peers and how ...
