In cosmology, intensity mapping is an observational technique for surveying the large-scale structure of the universe by using the integrated radio emission from unresolved gas clouds. In its most common variant, 21 cm intensity mapping, the 21cm emission line of neutral hydrogen is used to trace the gas. The hydrogen follows fluctuations in ...

Pronunciation follows convention outside the medical field, in which acronyms are generally pronounced as if they were a word (JAMA, SIDS), initialisms are generally pronounced as individual letters (DNA, SSRI), and abbreviations generally use the expansion (soln. = "solution", sup. = "superior").

An atom of neutral hydrogen consists of an electron bound to a proton.The lowest stationary energy state of the bound electron is called its ground state.Both the electron and the proton have intrinsic magnetic dipole moments ascribed to their spin, whose interaction results in a slight increase in energy when the spins are parallel, and a decrease when antiparallel.
The oldest known medical prescription text was found at Ebla, in modern Syria, and dates back to around 2500 BCE. [43] [44] [45] Modern prescriptions are actually extemporaneous prescriptions (from the Latin ex tempore, 'at/from the time'), [46] meaning that the prescription is written on the spot for a specific patient with a specific ailment ...
In astrophysics, the term "cosmography" is beginning to be used to describe attempts to determine the large-scale matter distribution and kinematics of the observable universe, dependent on the Friedmann–Lemaître–Robertson–Walker metric but independent of the temporal dependence of the scale factor on the matter/energy composition of the Universe.
