Behavioral Sciences &the Law, EarlyView.ABSTRACT This is a retrospective case study of an antisemitic lone actor terrorist who completed the deadliest attack against the Jewish community in American history. The analysis through the lens of the Terrorist Radicalization Assessment Protocol (TRAP‐18) finds that 72% of the warning indicators were present, including four proximal warning ...

Battery Energy, Volume 4, Issue 2, March 2025.Three biobased membranes are synthesized by crosslinking oxidized Kraft lignin with poly(ethylene glycol) diglycidyl ether of increasing molecular weights. After incorporation of solvated potassium salts, potassium batteries including these biobased gel polymer electrolytes are able to deliver a maximum specific capacity at 0.05 A g−1 as high as 130 ...

Acoustic‐driven surface cleaning with millimeter‐sized bubbles at translational resonance
Droplet, EarlyView.Time‐lapse visualization comparing bubble trajectories. The top panel (0 Hz) shows a bubble's linear path under no acoustic forcing, while the bottom panel (50 Hz) demonstrates the oscillatory motion induced by acoustic waves at a resonance mode. This mechanism holds promising potential for applications such as surface cleaning.

Deep Underground Science and Engineering, EarlyView.In this work, we propose an improved particle swarm optimization (PSO) algorithm and develop an improved PSO‐relevance vector machine (RVM) model as a substitute for traditional true‐triaxial testing. The model's high prediction accuracy was validated through comparisons with two other machine learning methods and five three‐dimensional Hoek–Brown type

Dynamic Characteristics of Fault Structure and Its Controlling Impact on Rock Burst in Mines
, 2021 As one of the most serious shock dynamic disasters in coal mining, rock burst only occurs under the certain geodynamic environment. Geodynamic is the necessary requirement for the occurrence of rock burst, and the disturbance of mining engineering is the
