Published Smoke covered 70% of California during biggest wildfire years
(via sciencedaily.com) Original source As much as 70 percent of California was covered by wildfire smoke during parts of 2020 and 2021, according to a new study.
Published Building a better sarcasm detector
(via sciencedaily.com) Original source Sarcasm is notoriously tricky to convey through text, and the subtle changes in tone that convey sarcasm often confuse computer algorithms as well, limiting virtual assistants and content analysis tools. So researchers have now developed a multimodal algorithm for improved sarcasm detection that examines multiple aspects of audio recordings for increased accuracy. They used two complementary approaches -- sentiment analysis using text and emotion recognition using audio -- for a more complete picture.
Published Virtual reality becomes more engaging when designers use cinematic tools
(via sciencedaily.com) Original source Cinematography techniques can significantly increase user engagement with virtual environments and, in particular, the aesthetic appeal of what users see in virtual reality.
Published How wildfires change soil chemistry
(via sciencedaily.com) Original source Severe wildfires can drive chemical changes in soil that affect ecosystem recovery and risks to human health. A new study finds broader surveillance and modeling of these changes could inform strategies for protecting lives, property and natural resources, and managing wildlife.
Published Improved wildfire smoke model identifies areas for public health intervention
(via sciencedaily.com) Original source The Canadian wildfires of June 2023 exposed a large portion of the Northeastern United States to unprecedented levels of smoke. A new model that combines wildfire smoke forecasts and data from ground-based sensors may help public health officials plan targeted interventions in areas most at risk for the negative health effects of unexpected smoke events and air pollution, according to scientists.
Published VR may pose privacy risks for kids: A new study finds parents aren't as worried as they should be
(via sciencedaily.com) Original source New research finds that, while an increasing number of minors are using virtual reality (VR) apps, not many parents recognize the extent of the security and privacy risks that are specific to VR technologies. The study also found that few parents are taking active steps to address those security and privacy issues, such as using parental controls built into the apps.
Published Biomechanical dataset for badminton performance analysis
(via sciencedaily.com) Original source In the sports industry, player data collection aids in personalized training feedback. Researchers have now gathered a detailed dataset and laid the foundation for delivering coaching assistance and feedback through the same. Utilizing wearable sensors and machine learning, their dataset offers real-time feedback and optimized movement suggestions. With over 7,763 badminton swings analyzed, stroke quality assessment offers valuable insights, making badminton training more accessible and affordable.
Published Wildfires in wet African forests have doubled in recent decades
(via sciencedaily.com) Original source Climate change and human activities like deforestation are causing more fires in central and west Africa's wet, tropical forests, according to the first-ever comprehensive survey there. The fires have long been overlooked.
Published Unveiling a polarized world -- in a single shot
(via sciencedaily.com) Original source Researchers have developed a compact, single-shot polarization imaging system that can provide a complete picture of polarization. By using just two thin metasurfaces, the imaging system could unlock the vast potential of polarization imaging for a range of existing and new applications, including biomedical imaging, augmented and virtual reality systems and smart phones.
Published Virtual reality environment for teens may offer an accessible, affordable way to reduce stress
(via sciencedaily.com) Original source Working with teens, researchers designed RESeT: a snowy virtual world with six activities intended to improve mood. In a 3-week study of 44 teens, researchers found that most of the teens used the technology about twice a week without being prompted and reported lower stress levels after using the environment.
Published Researchers develop a new way to instruct dance in Virtual Reality
(via sciencedaily.com) Original source Virtual reality dance made easier with crowd wave technique. Open source code can be downloaded for Quest 2 and 3.
Published Anthropologist documents how women and shepherds historically reduced wildfire risk in Central Italy
(via sciencedaily.com) Original source Fire management lessons from the past could help to improve resilience as the Mediterranean faces increased fire risk from climate change. How traditional land management practices once greatly reduced fuel for wildfires, and how these practices were forgotten, in part due to historical politics of classism and sexism.
Published Holographic displays offer a glimpse into an immersive future
(via sciencedaily.com) Original source Researchers have invented a new optical element that brings us one step closer to mixing the real and virtual worlds in an ordinary pair of eyeglasses using high-definition 3D holographic images.
Published Modeling broader effects of wildfires in Siberia
(via sciencedaily.com) Original source As wildfires in Siberia become more common, global climate modeling estimates significant impacts on climate, air quality, health, and economies in East Asia and across the northern hemisphere.
Published Child pedestrians, self-driving vehicles: What's the safest scenario for crossing the road?
(via sciencedaily.com) Original source Crossing roads for children can be a risky calculation, especially when the vehicles are self-driven. In a new study, researchers determined pre-teenage children are safest when self-driving vehicles signaled their intent to yield with a green light when they arrived at the intersection, then stopped.
Published Teaching a computer to type like a human
(via sciencedaily.com) Original source A new typing model simulates the typing process instead of just predicting words.
Published Unique field study shows how climate change affects fire-impacted forests
(via sciencedaily.com) Original source During the unusually dry year of 2018, Sweden was hit by numerous forest fires. A research team has investigated how climate change affects recently burnt boreal forests and their ability to absorb carbon dioxide.
Published Researchers shine light on rapid changes in Arctic and boreal ecosystems
(via sciencedaily.com) Original source Arctic and boreal latitudes are warming faster than any other region on Earth.
Published CO2 worsens wildfires by helping plants grow
(via sciencedaily.com) Original source By fueling the growth of plants that become kindling, carbon dioxide is driving an increase in the severity and frequency of wildfires, according to a new study.
Published Fires pose growing worldwide threat to wildland-urban interface
(via sciencedaily.com) Original source Fires that devastate wildland-urban interface areas are becoming more common around the globe, a trend that is likely to continue for at least the next two decades, new research finds. Such fires are especially dangerous, both because they imperil large numbers of people and because they emit far more toxins than forest and grassland fires.
