Subtractive Categories and Extended Subtractions
Applied Categorical Structures, 2009A pointed, finitely complete category \({\mathcal C}\) is subtractive if for every binary relation \(R\to X\times Y\) the corresponding relation \(\Hom_{{\mathcal C}}(C,R)\to\Hom_{{\mathcal C}} (C,X)\times\Hom_{{\mathcal C}}(C,Y)\) satisfies \((x,0_{C,Y})\in R\) whenever \((x,y)\in R\) and \((0_{C,X}, y)\in R\).

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-

How is Brexit likely to affect efforts to complete the European single market for capital and financial services? Brexit will shrink European capital markets by roughly 25 percent, with even larger declines in equity markets and pension funds. Approximately half of all euro transactions into foreign exchange take place in London, as do more than 75 ...

The purpose of subtraction of angiographic images is to demonstrate the vessels free of superimposed, disturbing image noise. With the aid of physical film parameters the theoretic basis for an optimum subtraction technique is presented.
