The accurate estimation of the temperature distribution of the GaN based power devices and optimization of the device structure is of great significance to possibly solve the self-heating problem, which hinders the further enhancement of the device performances. We present here the operando temperature measurement with high spatial resolution using Raman spectroscopy of AlGaN/GaN high electron mobility transistors (HEMTs) with different device structures and explore the optimization of the device thermal design accordingly. The lateral and depth temperature distributions of the single-finger HEMT were characterized.

Purpose: Adherence to home rehabilitation following total knee arthroplasty (TKA) is essential to reach optimal functional outcomes, especially in fast-track procedures. The aim of this study is to identify which sociodemographic and health factors significantly affect adherence in this context.
Methods: This is a secondary analysis of a randomized controlled trial with 52 patients.
Hand-Assisted Laparoscopic Surgery (HALS) as an Alternative to Unplanned Laparoscopic Conversion to Open Surgery (LCOS) in Colectomies for Acute Diverticulitis.

Morristown Medical Center, Department of Surgery, Morristown, NJ, USA.
Background: In difficult colorectal cases, surgeons may opt for a hand-assisted laparoscopic (HALS) colectomy or attempt a laparoscopic surgery that may require an unplanned conversion to open (LCOS). We aimed to compare the clinical outcomes of these 2 types of surgeries.
Methods: Colectomies for acute diverticulitis with a HALS or LCOS surgery were selected from the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) 2022 Targeted Colectomy Database.
Background: Wearable activity-measurement devices are increasingly popular among the public, but there is little information regarding their use among patients undergoing sports medicine procedures. The purpose of this study was to compare accelerometer-measured data with traditional patient-reported measures and to determine the trajectory of physical activity from before surgery to 1 year after anterior cruciate ligament reconstruction.
Materials And Methods: Adult patients undergoing primary anterior cruciate ligament reconstruction were enrolled in this prospective cohort pilot study.
Analysis of the Top Articles and Authors of the Journal of Orthopaedic Trauma and Bibliometric Comparison of Impact Factors of Orthopaedic Surgery Journals.
J Orthop Trauma
January 2025
Department of Orthopaedic Surgery, Medical City Denton, 3535 S Interstate 35, Denton, TX 76210, United States.
Objectives: To determine the top 100 cited authors and the top 20 articles in the Journal of Orthopaedic Trauma (JOT) and compare its impact factor to orthopaedic and non-orthopaedic surgery literature.
Design: Review.
Methods: The Web of Science database was used to determine the top 100 cited authors and top 20 cited articles that originated in JOT from 1995 to the present.
