Increases in skin perfusion and blood oxygen in the non‐exercising human limbs during exercise in the heat: Implications for control of circulation

Experimental Physiology, EarlyView.
Abstract Blood flow in the inactive limb tissues and skin is widely thought to decline during incremental exercise to exhaustion due to augmented sympathoadrenal vasoconstrictor activity, but direct evidence to support this view is lacking. Here, we investigated the inactive‐forearm haemodynamic (Q̇forearm${\dot{Q}}_{\mathrm{forearm}}$) and oxygenation

Effects of “Living High‐Training Low and High” on Sleep, Heart Rate Variability, and Psychological Responses in Elite Female Cyclists

European Journal of Sport Science, Volume 25, Issue 8, August 2025.
ABSTRACT “Living High‐Training Low and High” (LHTLH) is an altitude/hypoxic training method used to improve physical performance at sea level. The aim of this exploratory study was to investigate the effects of LHTLH on sleep, heart rate variability (HRV), and psychological stress in 10 elite/international level female cyclists (mean age: 17.3 ± 1.2 ...

Advances in Radiative Heat Transfer: Bridging Far‐Field Fundamentals and Emerging Near‐Field Innovations

Advanced Functional Materials, Volume 35, Issue 27, July 3, 2025.
This review synthesizes the evolution of radiative heat transfer, emphasizing the transition from far‐field to near‐field regimes. Traditional frameworks, such as Planck's law, are revisited alongside modern innovations like fluctuational electrodynamics. Applications span nanoscale thermal management, energy harvesting, and thermophotovoltaic systems.

In Situ Converting Conformal Sacrificial Layer Into Robust Interphase Stabilizes Fluorinated Polyanionic Cathodes for Aqueous Sodium‐Ion Storage

Advanced Science, Volume 12, Issue 25, July 3, 2025.
A unique interfacial conversion concept is proposed to establish robust cathode electrolyte interphase for stabilizing fluorinated polyanionic cathodes in aqueous electrolytes. In a typical case, the conformal Al2O3 sacrificial layer is predeposited on high‐voltage sodium vanadium oxy‐fluorophosphates cathode, which can progressively react with trace ...
