A Static Kropki Puzzle Pattern‐Based Shade Dispersion Technique for a Partially Shaded Photovoltaic Array

Energy Science & Engineering
Partial shading is crucial in reducing the performance of the photovoltaic (PV) array. The static reconfiguration is a viable option for alleviating the partial shading. The scattering of shade relies on its puzzle pattern.

UNC45B Reduction With Aging: A Myofiber-Intrinsic Promoting Factor for Sarcopenia. [PDF]

Aging Cell
Aging reduces Unc45b expression in fast‐twitch muscle, concomitant with reduction in muscle contractile capacity and muscle mass in mice. Unc45b deficiency initially reduces depolarization‐induced force, followed by a decline in fast‐twitch muscle mass in adult mice.

Epigenetic Modulation of the ACE System Underlies the Slow Aerobic Muscle Phenotype and Metabolic Exercise Response. [PDF]

FASEB J
Weekly moderate‐to‐vigorous activity (≈6 h) induced a marked increase in ACE promoter methylation in exercised knee‐extensor muscle. In combination with the ACE I/D genotype, ACE methylation contributed to ACE gene activity regulation in ways aligning with the slow‐twitch, aerobic muscle phenotype and its metabolic response to endurance exercise ...
