From Disruption to Stabilization: A Functional Governance Perspective on the Renewable Energy Transition in Montenegro

Environmental Policy and Governance, EarlyView.
ABSTRACT As global climate ambitions intensify, the key challenge lies not in setting renewable energy targets but in designing governance systems that can translate them into lasting transformation. The transition management literature has advanced a valuable research agenda for initiating change through niche innovations and participatory arenas in ...

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 ...

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.
