Real‐Time Fractional Control of an Electrohydraulic System Using Low‐Cost Technology

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Advances in control methods for electrohydraulic systems (EHS) improve performance by addressing nonlinearities and unknown parameters, although most studies are limited to numerical simulations. Furthermore, research with experimental validation often relies on high‐performance computing equipment, specialized data acquisition cards, and ...

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

Experimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Xenotime‐Type Rare‐Earth Orthophosphates REPO4 for Use as High‐Temperature Environmental Barrier Coatings

Journal of the American Ceramic Society, Volume 109, Issue 9, September 2026.
Can we make a more inexpensive and greener coating using naturally forming minerals? Xenotime mineral composition was determined to be (Y0.80Gd0.04Dy0.07Er0.05Yb0.04)PO4. Preliminary studies into REPO4 species showed compatable CTE match with SiC, formation of a multilayer reaction product that improves CMAS resistance, and parabolic growth rates ...
