Hydrogen‐Enhanced Stress Corrosion Cracking of Wire Arc Additive Manufactured Inconel 625 Superalloy in NaCl Solution: Mechanism of Synergistic Degradation

open access: yesMaterials and Corrosion, EarlyView.
Hydrogen‐enhanced SCC of WAAM Inconel 625 in 3.5 wt.% NaCl solution. Hydrogen charging reduces passive film stability (lower corrosion potential) and promotes pitting at Laves phase/matrix interfaces. Stress corrosion cracks propagate along Laves‐rich regions, leading to quasi‐cleavage brittle fracture.

Energy Transfer and Saving in a Nonlinear Coupled Vibrating System Based on the Method of Composite Synchronization Transmission

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The vibrating screening equipment in industry usually requires power supply to each driving motor to keep up with its normal operation. The self‐synchronization transmission motion of two motors can achieve the screening requirement and save electrical energy by driving one single inductor motor. Nevertheless, this technology is currently only

Multiple factors regulate resource use efficiency of Bothriochloa ischaemum‐dominated community in arid and semi‐arid regions

open access: yesNordic Journal of Botany, EarlyView.
Classical resource use efficiency (RUE) primarily quantifies productivity relative to resource uptake fluxes, while the capacity of long‐term soil resource pools to sustain ecosystem productivity remains understudied. We evaluated three ecosystem‐scale RUE indices (RUEC, RUEN, and RUEP) representing net primary productivity per unit soil organic carbon,

Glucocorticoids Impair the Airway Epithelial Barrier via Autophagy‐Associated Apoptosis in Asthma: A Preliminary Study Both In Vitro and In Vivo

open access: yesPediatric Discovery, EarlyView.
Mechanism underlying the negative effects of glucocorticoids on the airway epithelial barrier. Glucocorticoids upregulate autophagy factors and downregulate anti‐autophagy factors. Enhanced autophagy promotes excessive apoptosis and epithelial detachment, impairing airway barrier function.

Real‐World Distribution and Mortality Assessment of MDF and MELD Scores in Hospitalized Patients With Alcohol‐Associated Cirrhosis and Clinically Diagnosed Alcohol‐Associated Hepatitis

open access: yesPortal Hypertension &Cirrhosis, EarlyView.
This single‐center, retrospective study evaluated MDF, MELD, and etiology‐adjusted MELD (MELD[A]) scores in 92 hospitalized patients with alcohol‐associated cirrhosis and clinically diagnosed alcohol‐associated hepatitis. Six patients were lost to follow‐up and excluded from survival analyses (final n = 86).
