| DRES | dynamic random element stimuli |
|---|---|
| E(X) | expected value of the random variable X |
| MRF | Markov random field; medical record file; melanocyte-[stimulating hormone]-releasing factor; mesence... |
| RBS | random blood sugar; Roberts syndrome; Rutherford backscattering |
| RDB | random double-blind [trial] |
| continuous random variable | Continuous variable that may randomly assume any value in its domain but any particular value has no probability of occurring, only a probability density. (05 Mar 2000) |
|---|---|
| sample, random | A group selected randomly, solely by chance. (12 Dec 1998) |
| screen memory | In psychoanalysis, a consciously tolerable memory that unwittingly serves as a cover for another associated memory which would be emotionally painful if recalled. (05 Mar 2000) |
| selective memory | <psychology> Reception or retrieval of only some of the events in an experience. (05 Mar 2000) |
| pure random drift | That which has random components only with an average value of zero and no systematic effects. Brownian movement in a still container shows pure random drift but in the Mississippi shows a steady downstream tendency. (05 Mar 2000) |
| senile memory | Memory that is good for remote events, often in contrast to current events; characteristically seen in aged or demented persons. (05 Mar 2000) |
| short-term memory | <psychology> Temporary storage of information for a few seconds to hours, as opposed to long-term memory which refers to material stored for days, years, or a lifetime. (12 Dec 1998) |
| subconscious memory | Information not immediately available for recall. (05 Mar 2000) |
| discrete random variable | A random variable that may assume a countable number of values, each with a probability strictly greater than zero. (05 Mar 2000) |
| immunological memory | <immunology> The systems responsible for the situation where reactions to a second or subsequent exposure to an antigen are more extensive than those seen on first exposure (but See immunological tolerance. The memory is best explained by clonal expansion and persistence of such clones following the first exposure to antigen. (18 Nov 1997) |
| immunologic memory | <immunology> The ability to rapidly produce large quantities of specific immune cells after subsequent exposure to a previously encountered antigen. (09 Oct 1997) |
| ordered on-random off mechanism | A scheme for substrate binding and product release for multisubstrate enzymes; for a two-substrate two-product enzyme with this mechanism, the individuals have to bind to the enzyme in a distinct order; however, once the products are formed they may dissociate from the enzyme in either order. It has been suggested that pyruvate kinase has such a mechanism. The random on-ordered off mechanism is simply the reverse of this mechanism. (05 Mar 2000) |
| temporary memory | <psychology> Temporary storage of information for a few seconds to hours, as opposed to long-term memory which refers to material stored for days, years, or a lifetime. (12 Dec 1998) |
| long-term memory | That phase of the memory process considered the permanent storehouse of information which has been registered, encoded, passed into the short-term memory, coded, rehearsed, and finally transferred and stored for future retrieval; material and information retained in LTM underlies cognitive abilities.
