We describe an analogy between psychophysically measured effects in contrast masking, and the behavior of a simple integrate-andfire neuron that receives time-modulated inhibition. In the psychophysical experiments, we tested observers ability to discriminate contrasts of peripheral Gabor patches in the presence of collinear Gabor flankers. The data reveal a complex interaction pattern that we ...

hepatitis b virus (hbv) dna polymerase transactivated protein 1 (hbvdnaptp1) is a novel protein transactivated by hbv dna polymerase, screened by suppression subtractive hybridization technique (genbank accession no: ay450389). the biological function of hbvdnaptp1 was investigated in this study.we constructed a vector pcdna3.1 (-)/myc-his a-hbvdnaptp1 and used it to transfect acute monocytic l...

This paper describes an iterative hybrid (additive + subtractive) manufacturing approach for a titanium alloy (Ti6Al4V) part using laser hotwire directed energy deposition system (LHWDED) and traditional four-axis milling machine tool. The term is used to described where the additive subtractive operations occur in multiple stages rather than sequentially. It currently common produce entire by ...

Suppression subtractive hybridization (SSH) is frequently used to unearth differentially expressed genes on a whole-genome scale. Its versatility is based on combining cDNA library subtraction and normalization, which allows the isolation of sequences of varying degrees of abundance and differential expression. SSH is a complex process with many adjustable parameters that affect the outcome of ...

Nucleic acid sequences that differ in abundance between two populations (target sequences) can be cloned by multiple rounds of subtractive hybridization and amplification by PCR. These sequences can be cDNAs representing up-regulated mRNAs, or genomic DNAs from deletion mutants. We have derived an equation that describes the recovery of such sequences, and have used this to simulate the outcome...

This paper summarizes work undertaken in the area of modeling Shape Memory Alloy (SMA) and airfoil hysteresis using a Sugeno-type fuzzy modeling approach based on subtractive clustering. Two alternative approaches to develop a fuzzy model for hysteresis are proposed and evaluated. The first consists in building a mirror image of the lower curve in order to model both curves concurrently and the...

A parameterized deenition of subtractive oating point division algorithms is presented and veriied using PVS. The general algorithm is proven to satisfy a formal deenition of an IEEE standard for oating point arithmetic. The utility of the general speciication is illustrated using a number of diierent instances of the general algorithm.
