AI Article Synopsis
- - The study evaluated how the transverse components of tendon core sutures impact the strength of 6-strand tendon repairs, specifically comparing Tang and Yoshizu #1 methods with 4-strand repairs.
- - A total of 40 pig flexor tendons were tested under cyclic loading to measure gap formation, stiffness, and ultimate repair strength after 20 cycles.
- - Results showed that Yoshizu #1 repairs had a higher tendency to develop gaps and were significantly weaker compared to Tang repairs, highlighting the influence of transverse components on repair integrity.
Article Abstract
We assessed the effects of tendon core sutures' transverse components on the tensile resistance of two commonly used 6-strand tendon repairs. Tang and Yoshizu #1 repairs (6-strand) were tested and compared with 4-strand rectangular and double Kessler sutures (4-strand). A total of 40 pig flexor tendons were tested under cyclic loading. We recorded the number of tendons that formed a 2-mm gap between two tendon ends during 20 cycles of cyclic loading test, stiffness at the 1st and 20th loading cycle, and gap distance at the repair site and the ultimate repair strength at the 20th cycles. We found that the Yoshizu #1 repairs were more prone to form gaps and their ultimate strength was significantly lower than that of the Tang repair. The transverse components in a 6-strand repair affect gap formation and failure strength.

Accurate characterisation of seismic source mechanisms in mining environments is crucial for effective hazard mitigation, but it is complicated by the presence of anisotropic geological conditions. Neglecting anisotropic effects during moment tensor (MT) inversion introduces significant distortions in the retrieved source characteristics. In this study, we investigated the impact of ignoring anisotropy during MT inversion on the reliability of hazard assessment.

As a critical component of aero-engines, the processing quality of the blade has a significant impact on the engine's overall performance and service life. First, from the perspective of double abrasive grains, two finite element models-simultaneous and sequential scratches-are established. The interaction between the two abrasive grains affects not only the polishing force and chip formation but also the surface morphology of the processed workpiece.

Background: Most studies on pelvic floor muscle morphology (dimensions, shape) and its relationship with patient characteristic risk factors of pelvic floor dysfunction (demographics, medical history) have largely pertained to White individuals with vaginas. There is a need to establish normative data on pelvic floor muscle anatomy and identify morphological differences in racially diverse cohorts that may play a role in racial differences in the prevalence and pathophysiology of pelvic floor dysfunction.
Objective: (s): This study aimed to compare levator ani muscle thickness and levator hiatal morphology and their association with patient characteristics, between asymptomatic Black and White women-identifying individuals with a vagina of reproductive age.
In-Plane Anomalous Hall Effect Associated with Orbital Magnetization: Measurements of Low-Carrier Density Films of a Magnetic Weyl Semimetal.

Department of Physics, Tokyo Institute of Technology, Tokyo 152-8551, Japan.
For over a century, the Hall effect, a transverse effect under an out-of-plane magnetic field or magnetization, has been a cornerstone for magnetotransport studies and applications. Modern theoretical formulation based on the Berry curvature has revealed the potential that even an in-plane magnetic field can induce an anomalous Hall effect, but its experimental demonstration has remained difficult due to its potentially small magnitude and strict symmetry requirements. Here, we report observation of the in-plane anomalous Hall effect by measuring low-carrier density films of magnetic Weyl semimetal EuCd_{2}Sb_{2}.

Background: There is inconsistent evidence suggesting that people with chronic low back pain may differ in variability of repeated trunk movements compared to people without chronic low back pain. These inconsistencies may be due to low reliability and task dependence of movement variability measures, which can be addressed using multiple movement tasks and summary measures.
Methods: Participants with and without chronic low back pain were recruited.
