Subtraction consists in shortening the shape of the word. It operates on morphological bases such as roots, stems, and words in word-formation and inflection. Cognitively, subtraction is the opposite of affixation, since the latter adds meaning and form (an overt affix) to roots, stems, or words, while the former adds meaning through subtraction of ...

Science, 1993
A general problem in genetics is the identification of specific DNA sequence differences underlying phenotypic variation. These differences can be foreign DNA segments from an infecting pathogen that integrate into a host genome, spontaneously arising DNA rearrangements or point mutations that cause cancer in somatic tissues, or a wide variety of ...

Applied Optics, 1971
A holographic technique by which two dissimilar optical fields can be subtracted to yield only their difference is presented. The principle underlying this technique is that of optical interference between a holographically reconstructed field and a direct real-time one. Experimental verification is presented for the three cases of image-plane, fourier-

Subtraction digital holography
Applied Optics, 2003Overlapping of the desired (first-order) and undesired (zero-order) terms originating from the recorded primary-fringe patterns in digital holography is a problem without a real-time solution. We propose a procedure for suppressing the zero-order disturbance that is realizable in real time.

SUBTRACT: a computer program for modeling the process of subtractive hybridization
Bioinformatics, 1995We report on a new software tool, SUBTRACT, which allows the analysis of the possible strategies for an experiment based on a mathematical model of subtractive hybridization. The program helps the experimenter choose the optimal strategy and conditions for performing the reaction.

Optimization of subtractive hybridization in construction of subtractive cDNA libraries
Genetic Analysis: Biomolecular Engineering, 1994The efficiency of subtraction, integrity of residual single-stranded cDNA, and efficient recovery of nanogram quantities of double-stranded cDNA are the three most important factors affecting quality of subtractive hybridization reactions prior to subtractive cDNA library construction.

Suppression Subtractive Hybridization
2011Comparing two RNA populations that differ from the effects of a single independent variable, such as a drug treatment or a specific genetic defect, can establish differences in the abundance of specific transcripts that vary in a population dependent manner. There are different methods for identifying differentially expressed genes.
