Subtractive photonics is presented as a method for implementing photonic waveguides into any bulk CMOS or electronics process. Metal and glass are patterned in the backend layers by foundry to reveal suspended dielectric when metal etched away. This requires simple wet etch provides waveguiding of light up visible regime using broad transparency windows silicon oxides. Mechanical, chemical, con...

Improving Imbalanced Data Classification Accuracy by using Fuzzy Similarity Measure and Subtractive Clustering

Comparison of DNA from virulent strains of bacterial pathogens with DNA from less virulent or avirulent close relatives allows the identification of those genomic regions that are present only in virulent strains. Such regions are often associated with pathogenicity islands (PIs) and their characterisation can lead to a greater understanding of the pathogenesis of infectious diseases. There is ...

Here we describe a reliable method for isolating genes that are differentially expressed in two cell populations. The method is a combination of subtractive hybridization and PCR. Among many improvements to previously described methods is the incorporation of a new technology into the procedure which sterilizes(inactivates) PCR amplicons, and thereby overcomes the limitation of similar procedur...

Suppression subtractive hybridization (SSH) is a widely used method for separating DNA molecules that distinguish two closely related DNA samples. Two of the main SSH applications are cDNA subtraction and genomic DNA subtraction. In fact, SSH is one of the most powerful and popular methods for generating subtracted cDNA or genomic DNA libraries. The SSH method is based on a suppression PCR effe...

I present an algorithm for computationally mixing screen colors (RGB colors) subtractively, written for a general audience. The question it addresses is, “Given two colors specified by their RGB triplets, what RGB triplet should be used to represent the color that would arise if the two colors were mixed like paint colors, i.e., mixed subtractively?” The only way I can think of doing this in a ...

Cutting forces prediction is very important for cutting tool’s design and process planning. This paper presents a fuzzy cutting force modelling method using subtractive clustering for learning evaluation. In this method, subtractive clustering, combined with the least-square algorithm, identifies the fuzzy prediction model directly from the information obtained from the sensors. In the micro-mi...

A novel theory of subtractive hybridization including (or based on) the kinetic model of this process was proposed. A computer program modeling the process of subtraction was developed. Basing on the theory, a novel method of subtractive hybridization was proposed allowing routine comparison of genomes and products of genome expression. The method was applied to studies of the genetic mechanism...
