The Effect of the Gem‐Dimethyl Unit in the Gold‐Catalyzed Cycloisomerization of Aliphatic 1‐Bromoalkynes

European Journal of Organic Chemistry, EarlyView.
The conformational effect of the gem‐dimethyl motif and its isostere cyclopropane unit in the gold‐catalyzed cycloisomerization of aliphatic 1‐bromoalkynes has been studied. An unexpected inhibitory effect of the cyclopropane ring has been observed.

Absence seizures: Update on signaling mechanisms and networks

Epilepsia Open, EarlyView.
Abstract Absence seizures (AS) are a hallmark of genetic generalized epilepsies (GGE), characterized by brief episodes of impaired consciousness accompanied by electroencephalographic spike‐and‐wave discharges (SWDs). Traditionally attributed to cortico‐thalamo‐cortical (CTC) dysrhythmia, emerging evidence suggests a more intricate pathophysiological ...

Interpretable Tree‐Based Models for Predicting Short‐Term Rockburst Risk Considering Multiple Factors

Energy Science &Engineering, EarlyView.
Interpretable tree‐based models integrate microseismic, geological, and mining indicators to predict short‐term rockburst risk. SHAP analysis reveals the dominant role of energy‐related features and clarifies nonlinear factor interactions, enabling transparent and reliable early‐warning in deep coal mines.

Collaborative Optimization of Electromagnetic Interference Shielding, Adaptive Multi‐Color, and Thermal Camouflage of Basalt Fibers by Temperature‐Induced Gradient Structure Control

Exploration, EarlyView.
Polychromatic BFs with exceptional EMI and thermal shielding were fabricated based on a “plasma activation‐ALD bridging‐chemical plating‐post annealing treatments” gradient functionalization strategy. As prepared, basalt fiber/fabric demonstrates outstanding EMI SE of 53.47 dB and thermal infrared camouflage effect.

Rumen Mycobiome Thiamine Metabolism Contributes to Subacute Rumen Acidosis Tolerance in Goats Through Enhancing Epithelial Cell Proliferation via IGFBP2/IGF1 Axis Activation

Exploration, EarlyView.
Schematic illustration of the mechanism underlying the differences between SARA‐susceptible and SARA‐tolerant dairy goats fed a high‐concentrate diet. SARA‐susceptible goats (HCS) exhibit low rumen pH and metabolic decline, characterized by epithelial inflammation.
