Video anomaly detection is a research hotspot in the field of computer vision, attracting many researchers.Video anomaly detection differs from traditional video analysis. Usually, abnormal events occur only in a small percentage of the video pixels and therefore, it is unnecessary to focus on all the video pixels as most of them are harmless—called “the background”. Therefore, in the video feature extraction process, attention should be focused on a few detectable partial objects. Object detection is very complicated and consumes a significant amount of time during video processing. Therefore, ...

As the executor of life activities, proteins exert their specific biological functions through interactions such as forming protein complexes. The localization effects, crowding effects, and organelle microenvironments within cells are crucial for maintaining the structure and function of protein complexes. Recently, a research team led by Prof. ZHANG Lihua from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) has developed a glycosidic-bond-based mass-spectrometry-cleavable cross-linker, which improves the data ...

The COVID-19 pandemic has boosted the unnecessary use of antimicrobial chemicals linked to health problems, antimicrobial resistance, and environmental harm, warn more than two dozen scientists in the peer-reviewed journal Environmental Science & Technology. Their critical review details how quaternary ammonium compounds (QACs) are increasingly marketed and used in home, healthcare, education, and workplace settings despite the availability of safer alternatives and in some cases limited evidence of reduced disease transmission. “Disinfectant wipes containing ...

The race is on to provide high speed satellite internet to the Earth’s most remote areas. New tech companies such as Starlink, One Web, and Amazon’s Kuiper are competing with traditional, established “satcomm” companies such as Thuraya and Inmarsat to provide global high speed, low latency satellite internet across the globe. These new mega-constellations rely on tens of thousands of small low earth orbit satellites flying at a few hundred miles altitude. Network interconnectivity is a basic building block for providing the fastest, more reliable coverage to end users. While all these mega-constellations are driven to provide high ...

Considering the millions of research papers and reports from open domains such as biomedicine, agriculture, and manufacturing, it is humanly impossible to keep up with all the findings. Constantly emerging world events present a similar challenge because they are difficult to track and even harder to analyze without looking into thousands of articles.  To address the problem of relying on human effort in situations such as these, Lifu Huang, an assistant professor in the Department of Computer Science and core faculty at the Sanghani Center for Artificial Intelligence ...

Woods Hole, Mass. (Monday, May 8, 2023) -- New research provides clear evidence of a human “fingerprint” on climate change and shows that specific signals from human activities have altered the temperature structure of Earth’s atmosphere. Differences between tropospheric and lower stratospheric temperature trends have long been recognized as a fingerprint of human effects on climate. This fingerprint, however, neglected information from the mid to upper stratosphere, 25 to 50 kilometers above the Earth’s surface. “Including this information improves the detectability of a human fingerprint by a factor of five. Enhanced detectability occurs because the mid ...

Irvine, Calif., May 8, 2023 – While conducting a study of Petermann Glacier in northwest Greenland, researchers at the University of California, Irvine and NASA’s Jet Propulsion Laboratory uncovered a previously unseen way in which the ice and ocean interact. The glaciologists said their findings could mean that the climate community has been vastly underestimating the magnitude of future sea level rise caused by polar ice deterioration. Using satellite radar data from three European missions, the UCI/NASA team learned that Petermann Glacier’s grounding line – where ice detaches from the land bed and begins floating in the ocean – shifts substantially ...

It is often desirable to restrict flows—whether of sound, electricity, or heat—to one direction, but naturally occurring systems almost never allow this. However, unidirectional flow can indeed be engineered under certain conditions, and the resulting systems are said to exhibit chiral behavior. The concept of chirality is traditionally limited to single direction flows in one dimension. In 2021, however, researchers working with Taylor Hughes, a professor of physics at the University of Illinois Urbana-Champaign, ...

ITHACA, NY – A decline in New York’s childbirth rate is showing no sign of reversing and many women are waiting longer to have children, according to newly compiled data from the Program in Applied Demographics (PAD) in the Cornell Jeb E. Brooks School of Public Policy. In 2011, about 241,312 were born in New York. In 2021, that number was 210,742 – a 13% decline. New York state’s total fertility rate (TFR) – the average number of births a woman would have in her lifetime if current patterns continue – dropped from ...

Computer models are increasingly used to make decisions that affect nearly every aspect of modern life. This may include how to plan for the sustainable management of environmental resources to responding to pandemics. And while these models are often based on scientific data and research, they also incorporate subjective values, political interests, and human bias. With a prestigious national grant, a Virginia Tech researcher will dive into the ways that modeling processes can become more transparent while also incorporating diverse sources of information. Theodore Lim, an assistant professor ...

Wetlands, coastal areas and offshore waters near Alabama, Louisiana and Texas have more inactive oil and gas wells than producing ones, and the cost to permanently plug and abandon them could be $30 billion, University of California, Davis, researchers suggest. A paper published today in the journal Nature Energy examines the cost to plug 14,000 wells that are inactive, have not produced for five years and are unlikely to be reactivated in the Gulf of Mexico region, which is the epicenter of U.S. offshore oil and gas operations. The wells could pose future environmental and financial risks ...
