The valence band discontinuity (ΔE(v)) of Y2O3/InGaZnO4 (IGZO) heterojunctions was measured by a core-level photoemission method. The Y2O3 exhibited a band gap of -6.27 eV from absorption measurements. A value of ΔE(v) = 0.44 ± 0.21 eV was obtained by using the Ga 2p3/2, Zn 2p3/2 and in 3d5/2 energy levels as references. Given the experimental bandgap of 3.2 eV for the IGZO, this would indicate a conduction band offset ΔE(c) of - 2.63 eV in the Y2O3/IGZO heterostructures and a nested interface band alignment.

Influence of hip morphology on gluteal muscle biomechanics: a computational modeling study.

Background: Hip morphology variations, particularly in femoral neck shaft angle (NSA) and iliac wing width (IWW), have been associated with gluteal tendinopathy. However, the biomechanical implications of these morphological differences on gluteal muscle function are not well understood. This study investigates how NSA and IWW influence gluteal muscle forces, moment arms, and estimated tendon loads during walking, aiming to provide insights into the potential biomechanical pathways that may contribute to altered lateral hip loading patterns.

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder with an unclear pathogenesis to date. Neurofeedback (NFB) had shown therapeutic effects in patients with ASD. In this study,we analyzed the brain functional networks of children with ASD and investigated the impact of NFB targeting the beta rhythm training on these networks.

Electromagnetic radiation energy at millimeter wave frequencies, typically 30 GHz to 300 GHz, is ubiquitously used in society in devices for telecommunications; radar and imaging systems for vehicle collision avoidance, security screening, and medical equipment; scientific research tools for spectroscopy; industrial applications for non-destructive testing and precise measurement; and military and defense applications. Understanding the biological effects of this technology is essential. We have been investigating ocular responses and damage thresholds comparing various frequencies using rabbit eyes and dedicated experimental apparatus.
