Improvement of Arctic Sea Ice Type Concentration Retrieval From Microwave Remote Sensing Data
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingSea ice types, such as first-year ice and multiyear ice, can be discriminated based on radiometric and scattering signatures. However, changes in ice surface properties caused by processes like ice surface deformation and melt-refreeze events can lead to

Spectral characterization of three wearable electronic ultraviolet radiation dosimeters
Photochemistry and Photobiology, EarlyView.Excessive exposure to ultraviolet radiation poses significant public health risks, including DNA damage and skin‐related pathologies. Wearable electronic UV dosimeters enable accurate studies and quantification of solar UV‐radiation exposure on an individual level. Due to variations in the spectral distribution of solar radiation, the spectral mismatch

Photoprotective potential of gadusol against ultraviolet B radiation in melanocytes
Photochemistry and Photobiology, EarlyView.Gadusol protects melanocytes from ultraviolet B (UVB)‐induced damage without cytotoxicity. Abstract The increasing incidence of skin cancer, including melanoma, combined with the need for ultraviolet (UV) filters that are safe for human health and marine ecosystems, is driving the search for new photoprotective agents.

Radiometer-deployment subsystem
, 1972 A radiometer-deployment subsystem for the Nimbus E spacecraft was designed, developed, and qualified for space use. The dimensions of the radiometer are 0.9 meter square by 0.1 meter, and its weighs 32 kilograms.

Photochemistry and Photobiology, EarlyView.Three methods for substituting on‐site ambient ultraviolet radiation measurements for personal exposure measurements were investigated. Assuming spatial persistency of measurements from high‐grade instruments delivers lowest uncertainties up to distances of 82 km.

Photochemistry and Photobiology, EarlyView.Scaffold hopping strategy used to develop chalcones structure‐related to the avobenzone tautomer. Positive aspects of 2‐hydroxychalcones are highlighted. Abstract Chalcones are α,β‐unsaturated ketones with extended π‐conjugation, making them promising scaffolds for the development of organic UV filters.

Transfusion, EarlyView.Abstract Background Extremely preterm neonates often require red blood cell (RBC) transfusions derived from adult donors. These transfusions introduce adult hemoglobin into a neonatal hematopoietic system dominated by fetal hemoglobin (HbF), shifting the oxygen‐dissociation curve and increasing oxygen delivery to immature tissues.
