We report on the magnetoresistance of a two-dimensional electron gas subjected to an abrupt magnetic field gradient arising from a ferromagnetic stripe fabricated at its surface. A sharp resistance resonance effect is observed at B(p) due to the formation of two types of magnetic edge states that drift in opposite directions perpendicular to the magnetic field gradient for B

Aims: Polycystic ovary syndrome (PCOS) is closely associated with metabolic disorders such as insulin resistance and obesity, but the role of adipogenesis in its pathophysiology remains unclear. This study investigates the role of adipogenesis in PCOS development and evaluates whether hyperoside (HPS), an anti-adipogenic herbal compound, can improve PCOS by inhibiting adipogenesis.
Main Methods: A combination of in vivo and in vitro models was used to assess the impact of HPS on ovarian function, insulin resistance, and adipogenesis.
Quantification of training-induced alterations in body composition via automated machine learning analysis of MRI images in the thigh region: A pilot study in young females.

The maintenance of an appropriate ratio of body fat to muscle mass is essential for the preservation of health and performance, as excessive body fat is associated with an increased risk of various diseases. Accurate body composition assessment requires precise segmentation of structures. In this study we developed a novel automatic machine learning approach for volumetric segmentation and quantitative assessment of MRI volumes and investigated the efficacy of using a machine learning algorithm to assess muscle, subcutaneous adipose tissue (SAT), and bone volume of the thigh before and after a strength training.

Background And Aims: Steatotic liver disease (SLD) is the most common chronic liver disease strongly associated with metabolic dysfunction, but its pathogenesis remains incompletely understood. Exploring plasma circulating metabolites may help in elucidating underlying mechanisms and identifying new biomarkers for SLD.
Methods: We examined cross-sectionally the association between plasma metabolites and SLD as well as liver enzymes using data from 4 population-based cohort studies (Rotterdam study, Avon Longitudinal Study of Parents and Children, The Insulin Resistance Atherosclerosis Family Study, and Study of Latinos).
Fiber-optic vibration sensors have been studied widely owing to their anti-electromagnetic interference, corrosion resistance, and ease of integration and distribution. Previous reports primarily focused on the frequency detection of vibration signals. However, the amplitude sensitivity, noise-equivalent amplitude (NEA), and stability determine the sensing precision and accuracy of the device.

However, due to the inadequate temperature resistance of the optical dielectric film, maintaining a high level of precision in the rigid F-P cavity at elevated temperatures proves to be challenging. Volume Bragg grating (VBG) is a three-dimensional optical element modified by a femtosecond laser within a transparent glass medium to create a periodic refractive index distribution.
