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

The WAAM (Wire Arc Additive Manufacturing) process is well-respected because of its low cost and high deposition efficiency; nevertheless, the has limitations heat input forming accuracy. Hybrid manufacturing processes employing both additive subtractive can effectively reduce shape error. predictive modeling surface roughness in thermally assisted machining described this paper on basis three ...

In this study, we apply a non-negative matrix factorization approach for the extraction and detection of concepts or topics from electronic mail messages. For the publicly released Enron electronic mail collection, we encode sparse term-by-message matrices and use a low rank non-negative matrix factorization algorithm to preserve natural data non-negativity and avoid subtractive basis vector an...

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...
