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 ...

Background Dual-energy CT iodine maps are used to detect pulmonary embolism (PE) with CT angiography but require dedicated hardware. Subtraction CT, a software-only solution, results in iodine maps with high contrast-to-noise ratios.

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.

Universal Background Subtraction Using Word Consensus Models
IEEE Transactions on Image Processing, 2016Background subtraction is often used as the first step in video analysis and smart surveillance applications. However, the issue of inconsistent performance across different scenarios due to a lack of flexibility remains a serious concern.

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.

Algebra Universalis, 1994
A variety \({\mathcal V}\) (or an algebra \({\mathbf A})\) is said to be subtractive if it satisfies the identities \(s(x,x) \approx 0\) and \(s(x,0) \approx x\) for some binary term \(s\) and some nullary term 0. Such an \(s\) is called a subtraction term. Let \({\mathcal K}\) be a class of similar algebras, then a term \(p({\mathbf x}, {\mathbf y}) =

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.
