Mechanisms of Roadway Instability and Coupled Control Technology for Working Face Passing Through Fault Zones

Energy Science &Engineering, EarlyView.
This study mainly explores the instability characteristics of roadways near faults in the working face. Taking the 51104 transportation roadway of the 51104 working face in Shengxin Coal Mine as the main research object, through theoretical analysis, borehole inspection, numerical simulation and on‐site mine pressure observation, the instability ...

Optimization of Blasting‑Induced Roof Cutting Parameters in Key Stratum and Its Application in Gob‑Side Entry Retention Technology

Energy Science &Engineering, EarlyView.
This study addresses hard roof coal seam conditions by optimizing key stratum blasting‐cutting parameters through theoretical analysis, numerical simulation, and field tests. It proposes calculation methods for blast hole spacing and delay timing based on stress wave theory, controlling roadway deformation within 35 mm, thereby enhancing resource ...

Wide‐range and high‐resolution Young's modulus sensing enabled by a complementary indentation‐protrusion architecture

FlexMat, EarlyView.
A tactile sensor integrating indentation and protrusion sensing within a single platform enables accurate perception of object Young's modulus. This complementary architecture expands the detectable Young's modulus range to 25.8–2639.2 kPa and achieves an object recognition accuracy of 94.27%, outperforming indentation‐only (84.59%) and protrusion‐only

“Thinking Out Loud” and “Pivoting on the Fly”—An Empirical Review and Critical Incident Study of How Physicians Engage in Incidental Learning Amidst Complexity

Human Resource Development Quarterly, EarlyView.
ABSTRACT This study explores incidental learning among physicians navigating uncertainty during the COVID‐19 pandemic. Using a constructivist research design, we conducted a literature review of 13 empirical studies on incidental learning in complexity and analyzed critical incident interviews with 12 emergency medicine and intensive care physicians ...

A rare case of perineal neuralgia treated with ultrasound‐guided nerve block combined with water separation

Ibrain, Volume 11, Issue 1, Page 106-111, Spring 2025.
A middle‐aged man presented with a right indirect inguinal hernia in November 2020 and underwent laparoscopic high ligation of the right hernial sac. Intermittent acupuncture‐like pain in the skin of the right scrotum and medial thigh occurred 1 month after surgery and lasted for 6 months. Under ultrasound guidance, ilioinguinal nerve and genitofemoral
