Top Incomes, Heavy Tails, and Rank-Size Regressions
In economics, rank-size regressions provide popular estimators of tail exponents of heavy-tailed distributions. We discuss the properties of this approach when the tail of the distribution is regularly varying rather than strictly Pareto.

A Range Condition for Polyconvex Variational Regularization [PDF]
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.

A possible effect of atmospheric circulation in the daily variation of the earth's magnetic field. II. [PDF]
Seasonal features that are not related in a simple way to solar declination occur in the daily variation of the horizontal intensity of the earth's magnetic field at Tucson, as at Honolulu studied previously.

In this paper, functional convergence is derived for the partial maxima stochastic processes of multivariate linear processes with weakly dependent heavy-tailed innovations and random coefficients. The convergence takes place in the space of ${\mathbb{R}^

The weak Pareto law and regular variation in the tails
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

Regularly Varying Measures on Metric Spaces: Hidden Regular Variation and Hidden Jumps
We develop a framework for regularly varying measures on complete separable metric spaces $\mathbb{S}$ with a closed cone $\mathbb{C}$ removed, extending material in Hult & Lindskog (2006), Das, Mitra & Resnick (2013).

Existence and boundary behavior of positive solutions for a Sturm-Liouville problem [PDF]
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 ...

Regular Dependence of Total Variation on Parameters [PDF]
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.

Neuro Sliding Mode Control for Exoskeletons with 7 DoF
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 ...

Clinical Insights Into Hypercalcemia of Malignancy in Childhood
ABSTRACT Hypercalcemia of malignancy (HCM) is a rare but life‐threatening metabolic emergency in children that occurs in less than 1% of pediatric cancer cases, with a reported incidence ranging from 0.4% to 1.0% across different studies. While it is observed in 10%–20% of adult malignancies, pediatric HCM remains relatively uncommon.
