The data below tabulates standard electrode potentials (E°), in volts relative to the standard hydrogen electrode (SHE), at: . Temperature 298.15 K (25.00 °C; 77.00 °F); ...
Due to the minus sign, higher values of pIC 50 indicate exponentially more potent inhibitors. pIC 50 is usually given in terms of molar concentration (mol/L, or M), thus requiring IC 50 in units of M. [2] The IC 50 terminology is also used for some behavioral measures in vivo, such as the two bottle fluid consumption test.
The chart was designed by Ian Bailey [5] and Jan E. Lovie-Kitchin at the National Vision Research Institute of Australia. [1] [3] They described their motivation for designing the LogMAR chart as follows: "We have designed a series of near vision charts in which the typeface, size progression, size range, number of words per row and spacings were chosen in an endeavour to achieve a ...
The apparent dimension of this K value is concentration 1−p−q; this may be written as M (1−p−q) or mM (1−p−q), where the symbol M signifies a molar concentration (1M = 1 mol dm −3). The apparent dimension of a dissociation constant is the reciprocal of the apparent dimension of the corresponding association constant, and vice versa.
Apparent magnitude (m) is a measure of the brightness of a star, astronomical object or other celestial objects like artificial satellites. Its value depends on its intrinsic luminosity , its distance, and any extinction of the object's light caused by interstellar dust along the line of sight to the observer.
The atomic mass constant, denoted m u, is defined identically, giving m u = 1 / 12 m(12 C) = 1 Da. [ 4 ] This unit is commonly used in physics and chemistry to express the mass of atomic-scale objects, such as atoms , molecules , and elementary particles , both for discrete instances and multiple types of ensemble averages.
In statistics, the phi coefficient (or mean square contingency coefficient and denoted by φ or r φ) is a measure of association for two binary variables.. In machine learning, it is known as the Matthews correlation coefficient (MCC) and used as a measure of the quality of binary (two-class) classifications, introduced by biochemist Brian W. Matthews in 1975.
White Americans (sometimes also called Caucasian Americans) are Americans who identify as white people.In a more official sense, the United States Census Bureau, which collects demographic data on Americans, defines "white" as "[a] person having origins in any of the original peoples of Europe, the Middle East, or North Africa".
