From Inequality to Extremes and Back: A Lorenz Representation of the Pickands Dependence Function

Mathematics
We establish a correspondence between Lorenz curves and Pickands dependence functions, thereby reframing the construction of any bivariate extreme-value copula as an inequality problem.

Graphical Measures Summarizing the Inequality of Income of Two Groups

Statistics and Public Policy, 2022
Recently, Gastwirth proposed two transformations and of the Lorenz curve, which calculates the proportion of a population, cumulated from the poorest or middle, respectively, needed to have the same amount of income as top .

Delocalized Charge Transport in Thermoelectric Composites of Semiconducting Carbon Nanotubes Wrapped with a P‐Type Polymer

Advanced Electronic Materials, EarlyView.
Composites made of semiconducting carbon nanotubes and p‐type polymers, when adequately doped with molecular dopants, can exhibit highly delocalized charge carrier transport, showing high thermoelectric performances. The efficient charge delocalization is enabled by the reduced coulombic binding energy at high carrier concentration and the small ...

Assessing Economic Inequality Through the Lorenz Curve in Central and Eastern European Countries [PDF]

Ovidius University Annals: Economic Sciences Series
This study analyses economic inequality in Central and Eastern Europe (CEE) using tools such as the Lorenz Curve and the Gini coefficient. Originating in 1905, the Lorenz Curve, conceptualized by Max O.

Neural Information Processing and Time‐Series Prediction with Only Two Dynamical Memristors

Advanced Electronic Materials, EarlyView.
The present study demonstrates how simple circuits with only two memristive devices are utilized to perform high complexity temporal information processing tasks, like neural spike detection in noisy environment, or time‐series prediction. This circuit simplicity is enabled by the dynamical complexity of the memristive devices, i.e.

Trust‐region filter algorithms utilizing Hessian information for gray‐box optimization

AIChE Journal, EarlyView.
Abstract Optimizing industrial processes often involves gray‐box models that couple algebraic glass‐box equations with black‐box components lacking analytic derivatives. Such systems challenge derivative‐based solvers. The classical trust‐region filter (TRF) algorithm provides a robust framework but requires extensive parameter tuning and numerous ...
