Optimizing Hybrid Wind–Solar Systems in Barren Land Under Constraints Imposed by Atmospheric Aerosols

Earth's Future, Volume 14, Issue 10, October 2026.
Abstract By using a solar photovoltaic (PV) performance model and applying it to global data from 2000 to 2022, we demonstrated that although the net impact of aerosols on power generation was negative, this loss was almost entirely driven by soiling of panel surfaces and could be mitigated by developing an appropriate cleaning regime.

All Is Relative—A Call for Considering “Physiologically Informed” Control Conditions to Improve the Mechanistic Understanding of the Effects of Physical Exercise on Cognition

Scandinavian Journal of Psychology, Volume 67, Issue 5, Page 1246-1266, October 2026.
ABSTRACT There is a growing interest in elucidating the mechanisms that drive the benefits of physical exercise on cognitive performance. A key element for a better understanding of a particular phenomenon (e.g., the mediators of the exercise‐cognition interaction) is the selection of an appropriate control condition/group as the basis for causal ...

Lactate Thresholds and Performance in Young Cross-Country Skiers Before and After the Competitive Season: Insights from Laboratory Roller-Ski Tests in Normoxic and Hypoxic Conditions

Sports
Cross-country (XC) skiing imposes high physiological demands under hypoxic conditions at altitude. Lactate thresholds such as Onset Blood Lactate Accumulation at 4 mmol/L (OBLA4) and lactate plus 1 mmol/L above baseline (Bsln+1.0) are crucial for ...
