background: inclusion of inhomogeneity corrections in intensity modulated small fields always makes conformal irradiation of lung tumor very complicated in accurate dose delivery. objective: in the present study, the performance of five algorithms via monte carlo, pencil beam, convolution, fast superposition and superposition were evaluated in lung cancer intensity modulated radiotherapy planni...

For a piecewise linear intermittent map, the evolution of statistical averages of a class of observables with respect to piecewise constant initial densities is investigated and generalized eigenfunctions of the Frobenius-Perron operator P̂ are explicitly derived. The evolution of the averages are shown to be a superposition of the contributions from two simple eigenvalues 1 and λd ∈ (−1, 0), an...

We construct a geometry of interaction (GoI; dynamic modeling of Gentzen-style cut elimination) for multiplicativeadditive linear logic (MALL) by employing the Bucciarelli–Ehrhard MALL(I) of indexed linear logic to handle the additives. Our construction is an extension to the additives of the Haghverdi–Scott categorical formulation (a multiplicative GoI situation in a traced monoidal category) ...

We consider the demixing problem of two (or more) high-dimensional vectors from nonlinear observations when the number of such observations is far less than the ambient dimension of the underlying vectors. Specifically, we demonstrate an algorithm that stably estimate the underlying components under general structured sparsity assumptions on these components. Specifically, we show that for cert...

Various methods of linear system characterization are presented. Each method requires cataloging the system response to a set of input stimuli. The continuum orthonormal basis set response method, in principle applicable to all linear systems, has as special cases point-spread function and frequency response superposition integral characterizations. The piecewise isoplanatic approximation, samp...

A simplified model of arterial blood pressure intended for use in model-based signal processing applications is presented. The main idea is to decompose the pressure into two components: a travelling wave which describes the fast propagation phenomena predominating during the systolic phase and a windkessel flow that represents the slow phenomena during the diastolic phase. Instead of decomposi...
