Carbon, Nitrogen, and Corresponding Stable Isotope Signatures Reveal Channel Banks as Major Sediment Sources in a Tropical Agricultural Watershed

Land Degradation &Development, Volume 37, Issue 13, Page 9008-9020, 15 August 2026.
ABSTRACT Uncertainties about the applicability of δ13C and δ15N as tracers of sediment sources in tropical river basins highlight the need for more in‐depth investigations of these isotopes. This study therefore assessed the effectiveness of δ13C and δ15N signatures in discriminating sediment sources in an agricultural catchment in Northeast Brazil ...

Biochar‐Induced Shifts in Fungal Community Structure and Their Association With Soil Physical Properties in Degraded Soil From the Brazilian Semiarid

Land Degradation &Development, Volume 37, Issue 13, Page 9067-9083, 15 August 2026.
ABSTRACT Soil degradation compromises ecosystem functioning. Biochar, a carbon‐rich amendment, has gained attention as a promising strategy to enhance soil structure and restore microbial balance. This study investigated the effects of two biochars, cashew bagasse biochar (CBB) and a co‐pyrolyzed biochar produced from sewage sludge and cashew pruning ...

Shannon Entropy and Lévy Statistics for Machine Learning‐Assisted Spectral Sensing in Random Fiber Lasers With Magnetic Core–Shell Nanoscatterers

Nanophotonics, Volume 15, Issue 15, 13 August 2026.
Random laser emission was observed in a polymer optical fiber structure doped with magnetic Fe3O4@SiO2 core–shell nanoparticles. A direct relationship was demonstrated between Shannon entropy and Lévy statistics regarding intensity fluctuations in the emission modes. The analysis indicated a potential application in a proposed magnetic field and energy

Scanner‐agnostic artificial intelligence approach for fast bone scintigraphy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Purpose Current bone scintigraphy protocols often demand full‐count, 10–15 min scans to preserve image quality, and existing deep‐learning (DL) denoisers typically need to be retrained or retuned for each camera manufacturer. We introduce a scanner‐agnostic adaptive‐diffusion U‐Net designed to reconstruct diagnostic‐grade images from half‐time

Improvement in Outcomes of Childhood Acute Myeloid Leukemia Treatment: A Survival Analysis at a Reference University Hospital in Rio de Janeiro, Brazil

Cancer Reports, Volume 9, Issue 8, August 2026.
ABSTRACT Background Acute myeloid leukemia (AML) represents 15% to 20% of all pediatric acute leukemias and is responsible for nearly 30% of deaths in this population. While high‐income countries report overall survival (OS) rates near 75%, survival in Brazil remains significantly lower, ranging between 30% and 40%.
