A Range Condition for Polyconvex Variational Regularization [PDF]
Numerical Functional Analysis and Optimization, 2018 In the context of convex variational regularization it is a known result that, under suitable differentiability assumptions, source conditions in the form of variational inequalities imply range conditions, while the converse implication only holds under an additional restriction on the operator.

Regular Dependence of Total Variation on Parameters [PDF]
Real Analysis Exchange, 2004 If \(X\) is an interval, \(Y\) -- a metric space, \(T\) -- a set of parameters, and \(f: T\times X\to Y\) a function, then it can happen that \(f\) is measurable with respect to some \(\sigma\)-algebra while the function \(v:T\to X\), defined by \(v(t)\) equals to the total variation of \(f(t,\cdot)\), is not measurable.

The weak Pareto law and regular variation in the tails
Statistica, 2007 We show that the weak Pareto law, as used to characterize the tail behaviour of income distributions, implies regularly varying tail probabilities, but that the reverse implication does not hold. We also establish implications among other versions of the

Total variation regularization of shape signals [PDF]
2015 IEEE Conference on Computer Vision and Pattern Recognition (CVPR), 2015 This paper introduces the concept of shape signals, i.e., series of shapes which have a natural temporal or spatial ordering, as well as a variational formulation for the regularization of these signals. The proposed formulation can be seen as the shape-valued generalization of the Rudin-Osher-Fatemi (ROF) functional for intensity images.

Existence and boundary behavior of positive solutions for a Sturm-Liouville problem [PDF]
Opuscula Mathematica, 2016 In this paper, we discuss existence, uniqueness and boundary behavior of a positive solution to the following nonlinear Sturm-Liouville problem \[\begin{aligned}&\frac{1}{A}(Au^{\prime })^{\prime }+a(t)u^{\sigma}=0\;\;\text{in}\;(0,1),\\ &\lim\limits_{t ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Embryonal tumors comprise the majority of malignant central nervous system (CNS) neoplasms diagnosed in children under 3 years of age. Compared with their counterparts in older children, these tumors exhibit distinct molecular biology and a more aggressive clinical phenotype, while their management is complicated by the heightened ...

Neuro Sliding Mode Control for Exoskeletons with 7 DoF
Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2020 In this work, a novel neuro-sliding mode controller (NSMC) is developed for a 7 degree of freedom (DoF) upper limb exoskeleton. Even though the regular sliding mode controller (SMC) is very sufficient tool when the unknown dynamics of the system is time ...
