Systematic evolution of ligands by exponential enrichment ( SELEX ), also referred to as in vitro selection or in vitro evolution, is a combinatorial chemistry technique in molecular biology for producing oligonucleotides of either single-stranded DNA or RNA that specifically bind to a target ligand or ligands.
Exponential may refer to any of several mathematical topics related to exponentiation, including: Exponential function, also: Matrix exponential, the matrix analogue to the above. Exponential decay, decrease at a rate proportional to value. Exponential discounting, a specific form of the discount function, used in the analysis of choice over time.
Exponential decay is the process itself. Also, one can have exponential decay to a non-zero value --dependent on the physical system modeled. One doesn't usually talk about half-life in the context of exponential decay to a non-zero steady state value. Nephron 00:21, 19 March 2006 (UTC) Oppose.
e. In materials science and continuum mechanics, viscoelasticity is the property of materials that exhibit both viscous and elastic characteristics when undergoing deformation. Viscous materials, like water, resist shear flow and strain linearly with time when a stress is applied.
The Leslie matrix is a discrete, age-structured model of population growth that is very popular in population ecology named after Patrick H. Leslie. The Leslie matrix (also called the Leslie model) is one of the most well-known ways to describe the growth of populations (and their projected age distribution), in which a population is closed to migration, growing in an unlimited environment ...
Reverberation (commonly shortened to reverb ), in acoustics, is a persistence of sound after it is produced. [1] Reverberation is created when a sound or signal is reflected. This causes numerous reflections to build up and then decay as the sound is absorbed by the surfaces of objects in the space – which could include furniture, people, and ...
Mother. Ana Bantaș. Dimitrie or Demetrius [1] Cantemir ( Romanian pronunciation: [diˈmitri.e kanteˈmir] ⓘ, Russian: Дмитрий Кантемир; 26 October 1673 – 21 August 1723), also known by other spellings, was a Moldavian prince, statesman, and man of letters. [2] [3] He twice served as voivode of Moldavia (March–April 1693 ...
D16.9 .A2 1897. The Law of Civilization and Decay: An Essay on History is a book written by Brooks Adams in 1895. His intention was to prove that the rise and fall of civilizations follows a definite cycle of centralization and decay. Adams outlined this theory by sketching the patterns of major periods in western history, concentrating on ...
