Abstract. Logic preservation theorems often have the form of a syntax/semantics correspondence. For example, the Los-Tarski theorem asserts that a rst-order sentence is preserved b...
We prove that the equational theory of the process algebra BCCSP modulo completed simulation equivalence does not have a finite basis. Furthermore, we prove that with a finite alph...
Previous compressive sensing papers have considered the example of recovering an image with sparse gradient from a surprisingly small number of samples of its Fourier transform. T...
