Small‐Scale Spatial Variability in Carbon Fluxes Driven by Soil and Vegetation Characteristics in Wetlands of Trail Valley Creek, Canada

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract The microtopography of the Arctic tundra and the associated soil moisture (SM) gradient influence the net ecosystem‐atmosphere exchange of methane (CH4) and carbon dioxide (CO2). To quantify fine‐scale variability in a permafrost ecosystem, we measured growing‐season carbon fluxes with closed chambers at Trail Valley Creek, Canada from 2022 to

A Distinct Tryptophan Metabolic Phenotype Marks Severe Fatigue in Quiescent Crohn's Disease

JCC Plus, Volume 1, Issue 3, May 2026.
ABSTRACT Background Fatigue is a common and debilitating symptom in inflammatory bowel disease (IBD), but its underlying mechanisms remain unclear. Altered tryptophan metabolism may contribute to fatigue. Tryptophan is metabolized through the kynurenine, serotonin, and indole pathway, involving host and microbial processes. We aimed to explore the link

Comparison of time‐of‐flight and MIEZE neutron spectroscopy of H2O

Journal of Applied Crystallography, Volume 58, Issue 4, Page 1122-1137, August 2025.
We report a comparison of modulation of intensity with zero effort (MIEZE), a neutron spin–echo technique, and neutron time‐of‐flight spectroscopy, a conventional neutron scattering method. The basis of this comparison is provided by measurements performed on pure water under the same measurement conditions.We report a comparison of modulation of ...
