Increasing Respiration Weakens the Carbon Sink Over Two Decades in a Temperate Deciduous Forest

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
Using a 20‐year eddy covariance record from a temperate deciduous forest, we show that net carbon uptake declined over two decades. Both the trend and interannual variability in net carbon exchange were respiration driven, with warming winters and increasing late‐summer diffuse light driving the trend in respiration.

Assessing the Estimands and Estimates of Hospitalization Rates in Health Economics and Clinical Medicine

Health Economics, Volume 35, Issue 9, Page 1397-1405, September 2026.
ABSTRACT Even though data on hospital admissions are widely used in health research, hospitalization‐related estimands measured using these data are not always clearly conceptualized. Consequently, estimators of these quantities can have unclear rationales and undesirable properties.

SelExNet: A Self‐Supervised Physics‐Informed Framework for Multi‐Channel Joint RF and Gradient Waveform Optimization in 2D Spatially Selective Excitation

Magnetic Resonance in Medicine, Volume 96, Issue 3, Page 1219-1234, September 2026.
ABSTRACT Purpose To introduce SelExNet: a self‐supervised framework for two‐dimensional spatially selective excitation that jointly optimizes radiofrequency (RF) pulses and gradient waveforms, and extends to multi‐channel transmission MRI. Methods Building on prior RF‐only and joint RF‐gradient optimization approaches, SelExNet couples neural RF and ...

A Hands‐On Guide to Open‐Shell Calculations in Organic Chemistry: Radical Chemistry, Single Electron Transfer, and Energy Transfer

European Journal of Organic Chemistry, Volume 29, Issue 29, 7 August 2026.
Molecules with unpaired electrons, also known as open‐shell systems, are key intermediates in several light‐mediated or metal‐catalyzed transformations in organic chemistry. However, modeling this chemistry by density functional theory calculations is challenging.

Probabilistic quality assurance of biopsy DVH thresholds in HDR prostate brachytherapy under localization uncertainty

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background MR‐US guided biopsies support biologic correlation in HDR prostate brachytherapy, but steep dose gradients and millimeter‐scale localization uncertainty limit the validity of nominal biopsy doses. Purpose To assess how localization uncertainty affects the robustness of biopsy DVH dose thresholds in HDR prostate brachytherapy and to ...

AI‐assisted VMAT planning incorporating deep learning‐based dose prediction for head and neck cancer: feasibility of quality standardization and human intervention for irregular cases

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Volumetric‐modulated arc therapy (VMAT) represents a standard of care for head and neck cancer (HNC). However, treatment plan quality depends heavily on the planner's expertise, thereby challenging the standardization of treatment quality.

A preference‐integrated optimization system for medical physics shift scheduling

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Clinical shift scheduling for medical physicists is challenging given multidisciplinary roles and competing clinical, research, and service demands. Manual workflows often lack the flexibility and transparency needed for this complex field.
