In atomic, molecular, and optical physics, above-threshold ionization (ATI) is a multi-photon effect where an atom is ionized with more than the energetically required number of photons. [1] It was first observed in 1979 by Pierre Agostini and colleagues in xenon gas.
Different labs use different formulas and procedures to calculate the anion gap, so the reference range (or "normal" range) from one lab isn't directly interchangeable with the range from another. The reference range provided by the particular lab that performed the testing should always be used to interpret the results. [ 3 ]

The Chudnovsky algorithm is a fast method for calculating the digits of π, based on Ramanujan's π formulae.Published by the Chudnovsky brothers in 1988, [1] it was used to calculate π to a billion decimal places.
where J is the 3 J coupling constant, is the dihedral angle, and A, B, and C are empirically derived parameters whose values depend on the atoms and substituents involved. [3] The relationship may be expressed in a variety of equivalent ways e.g. involving cos 2φ rather than cos 2 φ —these lead to different numerical values of A , B , and C ...

The joule (/ dʒ uː l / JOOL, or / dʒ aʊ l / JOWL; symbol: J) is the unit of energy in the International System of Units (SI). [1] It is equal to the amount of work done when a force of one newton displaces a mass through a distance of one metre in the direction of that force.
Wide receiver A.J. Brown was caught on the bench reading the book at the end of the game. Stock down. Jake Elliott is having a tough time making all his kicks. Elliott did hit field goals of 32 ...
