Archiv der Pharmazie, Volume 356, Issue 1, January 2023., 2023 Nine Ag(I) complexes of Schiff bases containing thiophene, furan, and pyridine moieties were synthesized and tested for their in vitro antibacterial, antioxidant, and anticancer activities and DNA/bovine serum albumin binding. The nine Ag(I) complexes bound to calf thymus‐DNA by an intercalative binding mode, with the complex bearing a benzothiazole ...

Boundary Aware U-Net for Glacier Segmentation [PDF]
, 2023 Large-scale study of glaciers improves our understanding of global glacier change and is imperative for monitoring the ecological environment, preventing disasters, and studying the effects of global climate change. Glaciers in the Hindu Kush Himalaya (HKH) are particularly interesting as the HKH is one of the world's most sensitive regions for climate

Changes in Imja Tsho in the Mount Everest Region of Nepal [PDF]
, 2014 Imja Tsho, located in the Sagarmatha ( Everest) National Park of Nepal, is one of the most studied and rapidly growing lakes in the Himalayan range. Compared with previous studies, the results of our sonar bathymetric survey conducted in September of ...

Melt regimes, internal stratigraphy, and flow dynamics of three glaciers in the Alaska Range [PDF]
, 2012 We used ground-penetrating radar (GPR), GPS and glaciochemistry to evaluate melt regimes and ice depths, important variables for mass-balance and ice-volume studies, of Upper Yentna Glacier, Upper Kahiltna Glacier and the Mount Hunter ice divide, Alaska.

A New Method for Automatic Glacier Extraction by Building Decision Trees Based on Pixel Statistics
Remote SensingAutomatic glacier extraction from remote sensing images is the most important approach for large scale glacier monitoring. Commonly used band calculation indices to enhance glacier information are not effective in identifying shadowed glaciers and debris-

J.Phys.Conf.Ser.309:012012,2011, 2011 Liquid argon detectors, with mass up to 100 kton, are being actively studied in the context of proton decay searches, neutrino astrophysics and for the next generation of long baseline neutrino oscillation experiments to study the neutrino mass hierarchy and CP violation in the leptonic sector. The proposed Giant Liquid Argon Charge Imaging ExpeRiment (

A comparison of glacier melt on debris-covered glaciers in the northern and southern Caucasus [PDF]
, 2011 The glacier coverage in the Caucasus Mountains underwent considerable changes during the last decades. In some regions, the observed reduction in glacier area is comparable to those in the European Alps and the extent of supra-glacial debris increased on

Glacier shrinkage driving global changes in downstream systems
Proceedings of the National Academy of Sciences of the United States of America, 2017 Glaciers cover ∼10% of the Earth’s land surface, but they are shrinking rapidly across most parts of the world, leading to cascading impacts on downstream systems. Glaciers impart unique footprints on river flow at times when other water sources are low.

Spatiotemporal dynamic characteristics of typical temperate glaciers in China
Scientific Reports, 2021 China’s temperate glaciers have a relatively warm and humid climate and hydrothermal conditions at low latitudes. Temperate glaciers, however, have larger ablation, higher ice temperatures, relatively fast movement speeds, and a significant sliding ...
