An element of the periodic table, helium is what chemists call an inert gas. It's nontoxic, nonflammable, and is used in several industries because it is the element with the lowest boiling point, ...

This article addresses the periodic event-triggered adaptive output feedback control problem for networked system with unknown nonlinear dynamics. Based on the output-dependent periodic ...

The precursors of heavy elements might arise in the plasma underbellies of swollen stars or in smoldering stellar corpses.

An atom consists of a heavy center, called the nucleus, made of particles called protons and neutrons. An atom has lighter ...

Now, most of the atoms in the universe are the two simplest kinds: hydrogen, which has one proton, zero neutrons and one electron; and helium, which has two protons, two neutrons and two electrons. Of ...
