Prehistoric medicine consisted of a combination of very basic drugs (extracted from plants and herbs) and treatments consisting of ceremonies carried out by shamans using supernatural powers and objects (charms, spells, amulets, etc).

A simple characterization of the solvability of power flow equations is of great importance in the monitoring, control, and protection of power systems. In this paper, we introduce a sufficient condition for power flow Jacobian nonsingularity. We show that this condition is second-order conic representable when load powers are fixed. Through the incorporation of the sufficient condition, we pro...
