Objective: This study was designed to test defibrillation threshold (DFT) with the least number of fibrillation inductions using upper limit of vulnerability (ULV) and to describe the most practical ...

Black holes are regions of space where the density of matter becomes so high that space becomes sufficiently distorted that not even massless photons can escape the gravitational forces present.

Superconductors are game-changing materials that can transform everything, ranging from healthcare to energy transmission and quantum computing. But there’s a catch—they work at extremely low ...
