Spectral Modeling of the Dark Signal for UV and VIS‐NIR AvaSpec‐2048 CCD‐Array Spectrometers

Earth and Space Science, Volume 13, Issue 1, January 2026.
Abstract The use of CCD‐array spectrometers has substantially increased in recent years in many different fields. Although they have numerous advantages over conventional scanning spectrometers, they need to be thoroughly characterized to correct for various sources of error. This study focuses on the experimental characterization of the dark signal of

Integrated Assessment of Indoor Air Pollution and Associated Health Risks in a Hemodialysis Unit

Indoor Air, Volume 2026, Issue 1, 2026.
Indoor air quality (IAQ) is critical for protecting occupant health, particularly in healthcare settings such as hemodialysis (HD) units, where patients spend prolonged periods indoors. This study assessed IAQ in an HD treatment room over 1 year, identified pollutant sources using indoor/outdoor (I/O) ratios, and evaluated associated health risks for ...

Analysis of the Unprecedented Reduction in Antarctic Sea Ice During the Years 2022–2023

International Journal of Climatology, Volume 45, Issue 16, 30 December 2025.
This study examines the unprecedented Antarctic SIE decline in 2022–2023. Results show record‐low SIE with inhomogeneous spatial patterns, potentially driven by complex air‐sea interactions. Findings suggest internal climate variability influences Antarctic sea ice, mainly through wind pattern shifts linked to changes in the Amundsen Sea Low.

Confronting Episodic vs. Continuous Heat Sources in Long‐Lived Hot Orogens: Insights From Petrochronological Studies in the Nova Venecia Complex, Araçuaí Orogen (SE Brazil)

Journal of Metamorphic Geology, Volume 43, Issue 9, Page 863-890, December 2025.
ABSTRACT Orogenic belts that sustain elevated temperatures at intermediate crustal depths for tens of millions of years are known as hot orogens. The evolution of these hot orogens is largely influenced by thermal maturation, primarily driven by the distribution of heat‐producing elements (HPEs), such as K, Th and U in the overthickened crust.
