Small understory trees increase growth following sustained drought in the Amazon

New Phytologist, EarlyView.
Summary Droughts pose a major threat to the Amazon rainforest, yet the mechanisms enabling trees to maintain growth under prolonged drought remain poorly understood, particularly in the understory layer. We leveraged a 22‐yr Throughfall Exclusion (TFE) in a 1‐ha plot in eastern Amazonia, paired with a Control plot, to test whether small understory ...

Multi-Cell MIMO Downlink with Cell Cooperation and Fair Scheduling: a Large-System Limit Analysis

, 2010
We consider the downlink of a cellular network with multiple cells and multi-antenna base stations, including a realistic distance-dependent pathloss model, clusters of cooperating cells, and general "fairness" requirements. Beyond Monte Carlo simulation,

Improving the Protection of Aquatic Ecosystems by Dynamically Constraining Reservoir Operation Via Direct Policy Conditioning [PDF]

, 2014
Water management problems generally involve conflicting and non-commensurable objectives. Assuming a centralized perspective at the system-level, the set of Pareto-optimal alternatives represents the ideal solution of most of the problems.

Optimal timing to assess exercise‐induced oxidative stress: A systematic review and meta‐analysis

Experimental Physiology, EarlyView.
Abstract There is a lack of consensus on optimal timing to assess redox biomarkers post‐exercise, limiting methodological standardisation and linking oxidative stress to physiology. We determined optimal post‐exercise oxidative stress assessment times using three redox biomarkers: glutathione, F2‐isoprostanes and protein carbonyls.

Incidence and Risk Factors of Limb Ischaemia in Adult Patients Receiving Veno‐Arterial Extracorporeal Membrane Oxygenation: A Systematic Review and Meta‐Analysis

Nursing in Critical Care, Volume 31, Issue 2, March 2026.
ABSTRACT Background Limb ischaemia is a serious and potentially limb‐threatening vascular complication associated with veno‐arterial extracorporeal membrane oxygenation (V‐A ECMO). However, substantial heterogeneity has been observed in the reported incidence rates and identified risk factors among published studies.

In Situ Liquid‐Cell Transmission Electron Microscopy Insights Into Lithium‐Ion Battery Materials Degradation: Challenges and Emerging Solutions

Advanced Science, Volume 13, Issue 8, 9 February 2026.
Lithium‐ion battery degradation arises from complex, localized processes during operation, limiting long‐term performance. In situ electrochemical liquid cell TEM provides unique access to these mechanisms. This review summarizes degradation phenomena revealed by liquid cell TEM, traces the evolution of the three main cell designs, compares their ...

Push–Pull Bridged Stilbenes as Small Solvatochromic Aggregation‐Induced Emission Luminogen: Design and Excited‐state Deactivation Dynamics

Aggregate, Volume 7, Issue 2, February 2026.
A push–pull bridged stilbene (DpCBS[7]) demonstrates both solvatochromism and aggregation‐induced emission (AIE) within a compact molecular framework. Despite polarity‐dependent emission shifts, its fluorescence quantum yield remains low in solution due to ultrafast internal conversion.

Prediction of neutrophil nadir and recovery following paediatric haematopoietic cell transplantation with busulfan conditioning

British Journal of Clinical Pharmacology, Volume 92, Issue 2, Page 568-578, February 2026.
Aims In haematopoietic cell transplantation (HCT), neutropenia resulting from myelosuppression is an expected endpoint following busulfan‐based conditioning. However, if prolonged, neutropenia can lead to complications like serious infection and death.
