Luminosity functions are used to study the properties of large groups or classes of objects, such as the stars in clusters or the galaxies in the Local Group. Note that the term "function" is slightly misleading, and the luminosity function might better be described as a luminosity distribution. Given a luminosity as input, the luminosity ...
The Press–Schechter formalism predicts that the number of objects with mass between and + is: = (+) ¯ (+) / (() (+) /). where is the index of the power spectrum of the fluctuations in the early universe (), ¯ is the mean (baryonic and dark) matter density of the universe at the time the fluctuation from which the object was formed had gravitationally collapsed, and is a cut-off mass ...
Third, that if a person is put in a situation that in the past could have made them feel an emotion, they will react emotionally or experience emotions only if they are in a state of physiological arousal. [1] Participants were told they were being injected with a new drug called "Suproxin" to test their eyesight.

The definition of the situation is a fundamental concept in symbolic interactionism. [ 4 ] [ 5 ] It involves a proposal upon the characteristics of a social situation (e.g. norms, values, authority, participants' roles), and seeks agreement from others in a way that can facilitate social cohesion and social action.
An angry, drunken grandma has been busted in Tennessee for allegedly stabbing her daughter and grandson with a kitchen knife during a Thanksgiving Day argument.
Stock indexes drifted to a mixed finish on Wall Street as some heavyweight technology and communications sector stocks offset gains elsewhere in the market. The S&P 500 slipped less than 0.1% ...
For example, the position of an object x in the situation s is represented by the value of (,), where location is a function. Statements about such functions can be given using equality: l o c a t i o n ( x , s ) = l o c a t i o n ( x , s ′ ) {\displaystyle location(x,s)=location(x,s')} means that the location of the object x is the same in ...
