Improving ARTs: Microfluidics as a Tool for Sperm Selection
Andrology, EarlyView.ABSTRACT Sperm selection is a critical step in assisted reproductive technology (ART), as sperm quality directly influences embryo quality. In vivo, the female reproductive tract imposes several physical and physiological barriers that favors only the most optimal spermatozoa reaching the fertilization site.

ActuatorsA small-scale electro-hydrostatic actuator, termed miniHydrA, was developed based on biomechanical requirements for gait and integrated into an ankle exoskeleton. The key advantage of this actuator concept lies in its compact size and the low mass of its

Acute hot‐water immersion augments the diastolic blood pressure nocturnal dip in healthy adults
Experimental Physiology, EarlyView.Abstract Hot‐water immersion (HWI) has been shown to reduce 24 h ambulatory systolic blood pressure in hypertensive adults and might represent a preventative strategy for maintaining cardiovascular health in normotensive adults. The purpose of this study was to determine the time course of post‐HWI hypotension and test the hypothesis that a single HWI ...

Gear Pump Versus Variable Axial Piston Pump in Electro-Hydrostatic Servoactuators
ActuatorsThis paper presents a comparison of some different configurations of electro-hydrostatic actuators (EHA). The gear pump EHA has a simpler mechanical configuration, but the electronic power command circuits and the electric motor are in high demand due to

Experimental Physiology, EarlyView.Abstract Recent studies suggest that heat exposure may benefit cardiovascular health, but in overweight and obese older adults, the chronic effects of heat therapy on artery function are still uncertain. We aimed to compare the effects of 12 weeks (3×/week, 40 min) of aerobic exercise (EXE) to hot water immersion (HWI) and an inactive control group ...

Fisheries Management and Ecology, Volume 33, Issue 5, Page 1031-1043, October 2026.ABSTRACT To study variables that may trigger the dispersion of the currently expanding European catfish in its native distribution limits, 42 individuals were captured from Upper Lake Constance (lentic) and 42 from two streaming tributaries (lotic), fitted with pressure and temperature loggers, and released at the site of capture (control: lotic or ...

ActuatorsIn order to control an electro-hydrostatic actuator (EHS), as is well known in the literature, it is possible either to modify the speed and direction of rotation of the electric motor or to vary the displacement of the hydraulic pump.
