The increasing frequency and intensity of natural disasters call for rapid accurate damage assessment. In response, disaster benchmark datasets from high-resolution satellite imagery have been constructed to develop methods detecting damaged areas. However, these face significant challenges when applied previously unseen regions due the limited geographical disaster-type diversity in existing datasets. We introduce DAVI (Disaster Assessment with VIsion foundation model), a novel approach...
A total of 400, one day-old commercial broiler chicks were divided into five diet groups (negative control, positive control group with 55 ppm Zn-bacitracin, 15 β-glucan, 30 and 60 β-glucan) fed for six weeks. Ten broilers allotted to each 40 floor pens. Eight pens randomly assigned the 5 diets. Each was 6 weeks free access water diet. The survival rate, growth feed efficiency, conversion rate calculated. At end feeding trial, birds slaughtered, breast muscles deboned, quality parameters...
Biological concentrations of methylmercury (MeHg) are elevated throughout the Arctic Ocean; however, to date, major sources and spatial variability MeHg not well quantified. To identify inputs outputs shelf water column, we measured in seawater sediment samples from East Siberian Sea collected August September 2018. We found that pore were higher on slope than shelf, while slope. created a mass budget for benthic diffusion resuspension largely exceed other sources, such as atmospheric...

The sources of ultra-high-energy cosmic rays are still unknown, but assuming standard physics, they expected to lie within a few hundred megaparsecs from us. Indeed, over cosmological distances lose energy interactions with background photons, at rate depending on their mass number and properties photonuclear photon backgrounds. universe is not homogeneous such scales, hence the distribution arrival directions reflect inhomogeneities in galaxies; shorter loss lengths, stronger anisotropies....
OBJECTIVES: We aimed to study the effects of coronavirus disease 2019 (COVID-19) pandemic on adolescents’ mental health in Korea.METHODS: used data from Korea Youth Risk Behavior Survey 2018-2021 with 227,139 students aged 12-18 years. estimated differences depressive symptoms, suicidal ideation, and stress perception before (2018-2019) during (2020-2021) pandemic, as well (2019), first year (2020) of, second (2021) pandemic. also examined whether COVID-19 is statistically associated...
The increasing frequency and intensity of natural disasters demand more sophisticated approaches for rapid precise damage assessment. To tackle this issue, researchers have developed various methods on disaster benchmark datasets from satellite imagery to aid in detecting damage. However, the diverse nature geographical landscapes makes it challenging apply existing regions unseen during training. We present DAVI (Disaster Assessment with VIsion foundation model), which overcomes domain...
Telescope Array (TA) is the largest ultrahigh energy cosmic-ray (UHECR) observatory in Northern Hemisphere. A surface detector (SD) array covers approximately 700 km$^2$, and SD surrounded by three fluorescence (FD) stations.
