Abstract: Even for ultra deep sea applications, pressure housings using ceramics can obtain positive buoyancy because ceramics typically have an outstanding compressive strength-to-weight ratio and ...

Superconductors promise loss-free electricity, but most only work at extreme cold. Hydrogen-rich materials changed that—yet their inner workings remained hidden because they only exist under enormous ...

Blood pressure during a heart attack can be normal, low, or high. Low blood pressure during a heart attack is a medical emergency. A heart attack can cause high blood pressure due to adrenaline and ...

A consistent bedtime may play a meaningful role in lowering blood pressure, according to new research examining how sleep timing affects cardiovascular health. While most people think primarily about ...

Abstract: This article presents a high-sensitivity fiber optic gas pressure sensor based on the first-order harmonic Vernier effect (FHVE). The sensor comprises two parallel Fabry-Perot interferometer ...
