Adiabatic decompression of paraquadrupolar materials has significant potential as a cryogenic cooling technology. We focus on TmVO[Formula: see text], an archetypal material that undergoes a continuous phase transition to a ferroquadrupole-ordered state at 2.15 K.

Previously, this technique was practically limited to regularly shaped samples such as rectangular parallelepipeds, spheres, and cylinders [W. M.

Existing assessment instruments for minimally invasive inguinal hernia repair (IHR) have limitations with regards to reliability, validity, and usability. A cross-sectional study of six surgeons using a novel objective, procedure-specific, 8-item competency assessment for minimally invasive inguinal hernia repair (IHR-OPSA) was performed to assess inter-rater reliability using a "safe" vs.

- - The study developed the LC-CVS OPSA, an assessment tool that focuses on safety in laparoscopic cholecystectomy surgery, to improve surgical training and align with the American Board of Surgery's initiatives.
- - Expert surgeons rated ten surgical videos on a "safe" vs. "unsafe" scale, identifying 238 unsafe instances across various tasks and noting significant variations in ratings among the surgeons.
- - Analysis of feedback revealed key reasons for unsafe ratings, such as failure to achieve the critical view of safety, suboptimal techniques, and potential future complications, leading to modifications in assessment instructions to enhance reliability.
Laparoscopic cholecystectomy critical view of safety (LC-CVS): a multi-national validation study of an objective, procedure-specific assessment using video-based assessment (VBA).

Article Synopsis
- A new 6-item objective assessment tool for laparoscopic cholecystectomy (LC-CVS OPSA) was created to evaluate trainees’ skills, focusing on critical safe practices during surgery.
- The tool evaluates various aspects such as fundus retraction and visualization of important anatomical structures, with scoring categories ranging from "poor-unsafe" to "excellent-safe."
- Testing with expert surgeons showed high inter-rater reliability for assessing performance, indicating the tool's effectiveness in evaluating surgical trainees and its potential for integration into training programs alongside AI developments.
