A Retinomorphic Graphene Transistor Implementing Direction‐ and Velocity‐Selective Computation for In‐Sensor Image Stabilization

Small, EarlyView.
A multi‐gated ion‐gel graphene transistor architecture emulates spatiotemporal dendritic filtering inspired by biological direction‐selective retinal circuits. Leveraging distributed resistance‐capacitive ionic relaxation delays under combined excitation‐inhibition pulse routines, the solid‐state device exhibits programmable direction‐selective index ...

Experimental and design‐oriented research on fiber reinforced concrete segmental tunnel linings: A systematic review

Structural Concrete, EarlyView.
Abstract The use of fiber reinforced concrete (FRC) in precast tunnel segments is among the most established and representative applications of this material. Over the past two decades, numerous tunnel linings were constructed with partial or total substitution of conventional steel reinforcement by fibers, this yielding to quantifiable benefits in ...

When Time Stands Still: The Destructive Experience of Ambiguous Loss among Mothers of Combat Soldiers

Symbolic Interaction, EarlyView.
What happens when stories refuse coherence? This article examines ambiguous loss among mothers of combat soldiers, focusing on how prolonged waiting and uncertainty infiltrate everyday life, eroding sensemaking. Drawing on ethnographic interviews, it explores how mothers experience the contraction of time and space—manifested in suspended routines ...

Hemodynamic Effects of Prolonged Apneic Oxygenation in Laryngologic Surgery: A Randomized Controlled Pilot Trial

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Background Limited data exist on cardiocirculatory responses associated with extended periods of apnea during administration of high‐flow nasal oxygen for laryngologic surgery (apneic oxygenation with HFNO, AO‐HFNO). The possibility of hemodynamic compromise in the settings of acute hypercapnia, respiratory acidosis, hyperoxia, and IV ...
