Spin echo. In magnetic resonance, a spin echo or Hahn echo is the refocusing of spin magnetisation by a pulse of resonant electromagnetic radiation. [1] Modern nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI) make use of this effect. The NMR signal observed following an initial excitation pulse decays with time due to both ...
Chronic solvent-induced encephalopathy ( CSE) is a condition induced by long-term exposure to organic solvents, often—but not always—in the workplace, that lead to a wide variety of persisting sensorimotor polyneuropathies and neurobehavioral deficits even after solvent exposure has been removed. [1] [2] [3] This syndrome can also be ...
For example, δ H up to 40% was demonstrated for organic layers at 11 K. Graphene spin valves of various designs exhibited δ H of about 12% at 7 K and 10% at 300 K, far below the theoretical limit of 109%. The GMR effect can be enhanced by spin filters that select electrons with a certain spin orientation; they are made of metals such as cobalt.
Comprehensive sex education. Comprehensive Sexuality Education ( CSE) is a sex education instruction method based on a curriculum that aims to give students the holistic knowledge, attitudes, skills, and values to make healthy and informed choices in their sexual lives.

Site-directed spin labeling for EPR or paramagnetic relaxation-enhanced NMR also uses cysteine extensively. Reducing toxic effects of alcohol. Cysteine has been proposed as a preventive or antidote for some of the negative effects of alcohol, including liver damage and hangover. It counteracts the poisonous effects of acetaldehyde.
Common subexpression elimination. In compiler theory, common subexpression elimination ( CSE) is a compiler optimization that searches for instances of identical expressions (i.e., they all evaluate to the same value), and analyzes whether it is worthwhile replacing them with a single variable holding the computed value.
