A Year in the Bones: Investigating Bone Resorption Across a Reproductive Year in Wild Female Assamese Macaques

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Reproduction places considerable metabolic demands on females, particularly during pregnancy and lactation, when calcium homeostasis and bone metabolism are challenged. Urinary C‐terminal telopeptide of type I collagen (CTX‐I) offers a useful non‐invasive marker to assess bone resorption.

Block-sparse enhancement and detection of envelope modulation on noise for ship radiated noise

JASA Express Letters
Underwater target recognition is essential for ocean monitoring, with ship radiated noise analysis being a fundamental technique. This paper proposes a detection method based on block sparse enhancement. A harmonic dictionary is constructed and block sparse reconstruction is applied to enhance line spectrum components in the Detection of Envelope ...

Using Small Unoccupied Aerial System (sUAS) Multispectral Imagery to Compare Hydrodynamics Around Different Aged Patches of Marsh Vegetation

Ecohydrology, Volume 19, Issue 7, November/December 2026.
ABSTRACT Wetland vegetation influences water and sediment transport by altering flow resistance. Vegetation presence, stem density, leaf and stem morphology, and flexibility, among other characteristics, control the degree to which vegetation impacts transport patterns.

Evaluation of Radiation Tolerance of 6LiInP2Se6 for Neutron Science

physica status solidi (a), Volume 223, Issue 21, 11 November 2026.
6LiInP2Se6 is a room‐temperature semiconductor with favorable properties for neutron imaging applications. To evaluate real‐world suitability, samples were exposed to fluences up to 1015 n/cm2 s. Results from characterization of the bare crystals and measured alpha spectra recorded after fabricating the irradiated samples into detectors indicate ...

Runtime Bias Correction of Parameterized Lakes in Climate Models

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 11, November 2026.
Abstract A novel approach is presented for improving atmosphere‐lake heat and evaporative fluxes in global and regional climate models. The method involves deriving and applying runtime corrections to lake surface water temperature (LSWT) and lake ice, to reduce biases in the climatological annual cycle of these quantities.

Shipborne Measurements of Mineral Dust and Black Carbon Aerosols Over the Southern Ocean in the Austral Summer

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Atmospheric mineral dust and black carbon (BC) aerosols play important roles in the Earth's climate system, yet direct observations over the Southern Ocean (SO) are scarce. In this study, we present the characteristics of airborne water‐insoluble particles (WIPs) collected during a cruise of the R/V Shirase in the Australian and Indian sectors
