50% body weight loading reduces stature increases and lumbar disc expansion from 4 h hyper‐buoyancy floatation versus 15 min sitting upright

Experimental Physiology, EarlyView.
Abstract Microgravity is associated with stature increases, back pain and post‐flight intervertebral disc (IVD) herniation. This study aims to determine whether 30 s seated 50% body weight (BW) axial loading is comparable to 15 min sitting upright in 1 g upon changes in stature, anterior lumbar IVD height (via ultrasound), passive vertebral stiffness ...

Computational Tools for Thermodynamic Teaching in Chemical and Metallurgical Engineering Courses

Computer Applications in Engineering Education, Volume 33, Issue 4, July 2025.
ABSTRACT Thermodynamics is considered, among many engineering students, a very difficult branch of physics, especially regarding phase equilibria modeling, which usually often requires the use of commercial software and/or complex algorithms, rarely available for the general public. The present article provides new and simple Python numerical codes for

Improving Damping Performance of Thermoplastic Composite Materials Through SMC‐TPU Hybridization

Journal of Applied Polymer Science, Volume 142, Issue 22, June 10, 2025.
ABSTRACT This study investigates the mechanical and dynamic thermomechanical properties of thermoplastic sheet molding compounds (TP‐SMC) combined with thermoplastic polyurethane (TPU) to enhance damping while maintaining structural integrity. The methodology uses SMC, a residual material from UD tape processing, to further enhance sustainability.

Specific fibre areas in the femoral footprint of the posterior cruciate ligament act as a major contributor in resisting posterior tibial displacement: A biomechanical robotic investigation

Knee Surgery, Sports Traumatology, Arthroscopy, Volume 33, Issue 6, Page 2010-2018, June 2025.
Abstract Purpose Similar to the anterior cruciate ligament, the femoral footprint of the posterior cruciate ligament (PCL) is composed of different fibre areas, possibly having distinct biomechanical functions. The aim of this study was to determine the role of different fibre areas of the femoral footprint of the PCL in restraining posterior tibial ...

Synthetic antibodies targeting EphA2 induce diverse signaling‐competent clusters with differential activation

Protein Science, Volume 34, Issue 6, June 2025.
Abstract The receptor tyrosine kinase EphA2 interacts with ephrin (Efn) ligands to mediate bi‐directional signals that drive cellular sorting processes during tissue development. In the context of various cancers, EphA2 can also drive invasive metastatic disease and represents an important target for cancer therapeutics.
