Evidence that transverse variability of critical current density can greatly mitigate screening current stress in high field REBCO magnets.

Plastic damage of REBCO (REBaCuO, where RE=rare earth) coated conductors by screening current stress (SCS) is a significant concern for ultra-high-field superconducting magnets. Indeed, the third Little Big Coil (LBC3), a REBCO magnet that generated a record, high field of 45.5 T, showed wavy plastic damage produced by excess SCS in all pancakes except two made with single-slit conductors having their slit edges pointing inward towards the magnet center.

Pilot Study on the Relationship Between Different Lower Limb Raising Velocities and Trunk Muscle Contraction in Active Straight Leg Raise.

Background/objectives: The active straight leg raise requires intricate coordination between the hip, knee, pelvis, and spine. Despite its complexity, limited research has explored the relationship between lower limb raising velocity and trunk muscle motor control during an active straight leg raise in healthy individuals. This study aimed to explore the potential effects of increased lower limb raising velocity on core muscle contractions during active straight leg raises.

Tumor infiltration of inactive CD8 + T cells was associated with poor prognosis in Gastric Cancer.

Background: Gastric cancer (GC) shows limited response to immune checkpoint inhibitors due to its complex tumor immune microenvironment (TIME). This study explores the functions of various immune cells in the complex TIME in GC.

Methods: We assessed CD8 + T-cell infiltration of GC tissues by immunohistochemistry, and performed single-cell RNA sequencing (scRNA-seq) of tumor and normal tissues from 34 patients with GC.

Hypermagnesemia caused by fecal-mass obstruction in stenotic rectal cancer following preoperative administration of magnesium citrate.

Background: Hypermagnesemia is a rare complication, leading to fatal cardiovascular and respiratory conditions. We present severe hypermagnesemia developed in a patient with a rectal stenosis after pretreatment with oral magnesium citrate for rectosigmoid surgery.

Case Presentation: A 78-year-old woman demonstrated consciousness disturbance, muscle weakness, and respiratory depression requiring tracheal intubation after preparation with oral magnesium for rectosigmoid surgery.

Optically Pumped and Electrically Switchable Microlaser Array Based on Elliptic Deformation and Q-Attenuation of Organic Droplet Oscillators.

Conventional laser panel displays are developed through the mass integration of electrically pumped lasers or through the incorporation of a beam steering system with an array of optically pumped lasers. Here a novel configuration of a laser panel display consisting of a non-steered pumping beam and an array of electrically Q-switchable lasers is reported. The laser oscillator consists of a robust, self-standing, and deformable minute droplet that emits laser through Whispering-Gallery Mode resonance when optically pumped.
