BACKGROUND An unknown input function can be determined by deconvolution using the systemic bolus input function (r) determined using an experimental input of duration ranging from a few seconds to many minutes. The quantitative relation between the duration of the input and the accuracy of r is unknown. Although a large number of deconvolution procedures have been described, these routines are ...

Colour deconvolution is a method used in diagnostic brightfield microscopy to transform colour images of multiple stained biological samples into images representing the stain concentrations. It is applied by decomposing the absorbance values of stain mixtures into absorbance values of single stains. The method assumes a linear relation between stain concentration and absorbance, which is only ...

The deconvolution kernel density estimator is a popular technique for solving the deconvolution problem, where the goal is to estimate a density from a sample of contaminated observations. Although this estimator is optimal, it suffers from two major drawbacks: it converges at very slow rates (inherent to the deconvolution problem) and can only be calculated when the density of the errors is co...

The first, self-consistent calculations are presented of the cosmological, H2-dissociating UV background produced during the epoch of reionization by the sources of reionization. Large-scale radiative transfer simulations of reionization trace the impact of all the ionizing starlight on the IGM from all the sources in our simulation volume down to dwarf galaxies of mass ∼ 10 M⊙, identified by v...

rofessor Werner Felix Dutz (Figure 1), an Austrian pathologist, joined the faculty of the School of Medicine of Shiraz University in southern Iran in 1959. He and his wife, Dr. Elfriede Kohout, also a pathologist, had come to Iran for only a two-year appointment at an academic institution in a Third World Country, to meet the existing requirements for eligibility of immigrant status in the U.S....

We consider bipartite mixed states ρ in a d ⊗ d quantum system. We say that ρ is PPT if its partial transpose 1⊗ T(ρ) is positive semidefinite, and otherwise ρ is NPT. The well-known Werner states are divided into three types: (a) the separable states (the same as the PPT states); (b) the one-distillable states (necessarily NPT); and (c) the NPT states which are not one-distillable. We give sev...

The basic idea of decision emergence is to generate the prefered decision alternative instead of assuming it as exogeneously given like in neo-classical economics and game theory. The particular problem of ultimatum proposals has been selected in order to rely on experimental observations when speculating how choices emerge. Our approach distinguishes primary and secondary concerns of ultimatum...

In this paper we present a general framework of the state space approach for blind deconvolution. First, we review the current state of the art of blind deconvolution using statespace models, then give a new insight into blind deconvolution in the state-space framework. The cost functions for blind deconvolution are discussed and adaptive learning algorithms for updating external parameters are...
