  • biomedical package — (language, library, statistics)   (BMDP) A statistical language and library of over forty statistical routines developed in 1961 at UCLA, Health Sciences Computing Facility under Dr. Wilford Dixon. BMDP was first implemented in Fortran for the IBM 7090. Tapes of the original source were distributed for free all over the world. BMDP is the second iteration of the original BIMED programs. It was developed at UCLA Health Sciences Computing facility, with NIH funding. The "P" in BMDP originally stood for "parameter" but was later changed to "package". BMDP used keyword parameters to defined what was to be done rather than the fixed card format used by original BIMED programs. BMDP supports many statistical funtions: simple data description, survival analysis, ANOVA, multivariate analyses, regression analysis, and time series analysis. BMDP Professional combines the full suite of BMDP Classic (Dynamic) release 7.0 with the BMDP New System 2.0 Windows front-end.
  • bipolar transistor — (electronics)   A transistor made from a sandwich of n- and p-type semiconductor material: either npn or pnp. The middle section is known as the "base" and the other two as the "collector" and "emitter". When used as an amplifying element, the base to emitter junction is in a "forward-biased" (conducting) condition, and the base to collector junction is "reverse-biased" or non-conducting. Small changes in the base to emitter current (the input signal) cause either holes (for pnp devices) or free electrons (for npn) to enter the base from the emitter. The attracting voltage of the collector causes the majority of these charges to cross into and be collected by the collector, resulting in amplification. Contrast field effect transistor.
