Cross-polarization coupling in polarization maintaining fiber induced by periodic mechanical stress

Научно-технический вестник информационных технологий, механики и оптики, 2023
One of the applications of polarization maintaining (PM) fibers is the creation of various sensors including level and hydrostatic pressure sensors. An external mechanical stress on a PM fiber causes cross-polarization coupling.

Glucocorticoid‐sensitive period of corticotroph development—Implications for mechanisms of early life stress

Journal of Neuroendocrinology, 2023
Abstract Corticotrophs are intermediaries in the hypothalamic–pituitary–adrenal (HPA) axis, which plays a crucial role in stress response in vertebrates. The HPA axis displays an intricate mode of negative feedback regulation, whereby the peripheral effector, cortisol inhibits the secretion of its upstream regulator ...

Influence of Uniaxial Tensile Stress on the Mechanical and Piezoelectric Properties of Short-period Ferroelectric Superlattice [PDF]

Nanoscale Research Letters, 2009
Tetragonal ferroelectric/ferroelectric BaTiO3/PbTiO3 superlattice under uniaxial tensile stress along the c axis is investigated from first principles. We show that the calculated ideal tensile strength is 6.85 GPa and that the superlattice under the loading of uniaxial tensile stress becomes soft along the nonpolar axes.

Effect of Curing Stress and Period on the Mechanical Properties of Cement-Mixed Sand

Soils and Foundations, 2011
ABSTRACT Cement mixing is one of the popular ground improvement technologies in geotechnical engineering practice. In order to effectively and confidently design cement-mixed soil structures for specific purposes, its stress-strain behavior needs to be well understood. Though there have been many studies on cement-mixed soils using different types of

Assur graphs, marginally jammed packings, and reconfigurable metamaterials

Physical Review Research, 2023
Isostatic frames are mechanical networks that are simultaneously rigid and stress-free. Isostaticity itself is a powerful concept in understanding phase transitions in soft matter and designing mechanical metamaterials.

Periodic Mechanical Stress Induces Extracellular Matrix Expression and Migration of Rat Nucleus Pulposus Cells Through Src-GIT1-ERK1/2 Signaling Pathway

Cellular Physiology and Biochemistry, 2018
Background/Aims: Periodic mechanical stress has been shown to promote extracellular matrix (ECM) synthesis and cell migration of nucleus pulposus (NP) cells, however, the mechanisms need to be fully elucidated.
