We analyze charge-e/4 quasiparticle tunneling between the edges of a point contact in a non-Abelian model of the nu = 5/2 quantum Hall state in the presence of a finite voltage difference using the time-dependent density-matrix renormalization group method. We confirm that, as the voltage decreases, the system is broken into two pieces. In the limits of small and large voltage, we recover the results expected from perturbation theory about the infrared and ultraviolet fixed points. We test our methods by finding the analogous nonequilibrium current through a point contact at nu = 1/3.

Clinical outcomes and biomechanics in bicruciate-retaining total knee arthroplasty.
J Exp Orthop
January 2025
Department of Orthopaedic Surgery, Faculty of Medicine The University of Tokyo Tokyo Japan.
Purpose: To clarify the influence of biomechanics on post-operative clinical outcomes in bicruciate-retaining total knee arthroplasty (BCR-TKA).
Methods: Severe medial osteoarthritis who underwent BCR-TKA were examined. Each patient was asked to perform a squat (weight-bearing [WB]) and active assisted knee flexion (non-WB [NWB]) under single fluoroscopy surveillance.
Performance of a Toric, Monthly, Soft Contact Lens in Digital Device Users.

Research Department, Southern College of Optometry, Memphis, TN, USA.
Purpose: To determine the performance of TOTAL30 for Astigmatism (T30fA; Alcon; Fort Worth, TX, USA) contact lenses (CLs) in existing CL wearers who are also frequent digital device users.
Methods: This 1-month, 3-visit study recruited adult, 18- to 40-year-old subjects who were required to use daily digital devices for at least 8 hours per day. All subjects were refit into T30fA CLs.
Empowering Communication in Medicine: A Workshop Approach to Improve Presentation Skills for Ear, Nose, and Throat Specialists.

Department of Otolaryngology - Head and Neck Surgery, University of Fukui, Yoshida, JPN.
Introduction Effective communication is crucial for healthcare professionals, impacting patient care and interdisciplinary collaboration. However, medical education often lacks structured training in communication and presentation techniques. Herein, we evaluate the efficacy of structured workshops aimed at enhancing presentation skills among ear, nose, and throat (ENT) doctors through training in visual material design and concise verbal communication, including elevator pitches.

Reduced weight-bearing during spaceflight has been associated with musculoskeletal degradation that risks astronaut health and performance in transit and upon reaching deep space destinations. Previous rodent experiments aboard the international space station (ISS) have identified that the spaceflight-induced molecular arthritic phenotype was characterized with an increase in oxidative stress. This study evaluated if treatment with a superoxide dismutase (SOD) mimetic on orbit could prevent spaceflight-induced damage to the knee and hip articular cartilage, and the menisci in rodents.

Background: The presence of mandibular third molars has been associated with the risk of mandibular fractures, highlighting the need for comprehensive studies considering the interaction with other mandibular structures. This study investigates how mandibular third molars and neighboring tissues can influence the structural fragility of the mandible using finite element analysis.
Material And Methods: A finite element analysis study following the guidelines proposed by RIFEM 1.
