Approximate Synthesis of Н_∞ – Controllers in Nonlinear Dynamic Systems over a Semi-Infinite Time Period

Advanced Engineering Research
Introduction. Problems and methods of finding Н∞ – control are the basis of modern control theory. They are actively used to develop robust controllers, especially in aircraft control systems under limited external actions.

Social Exchange and Reciprocal Integration Between Migrants and Locals at Work

Human Resource Management Journal, EarlyView.
ABSTRACT Workplaces are pivotal “contact zones” where migrants and locals negotiate access to jobs, resources, and recognition, yet HRM research has rarely examined how everyday encounters generate integrated relationships at work. This conceptual paper introduces reciprocal integration as a workplace‐anchored social exchange process: the emergent ...

Computing Skinning Weights via Convex Duality

Computer Graphics Forum, EarlyView.
We present an alternate optimization method to compute bounded biharmonic skinning weights. Our method relies on a dual formulation, which can be optimized with a nonnegative linear least squares setup. Abstract We study the problem of optimising for skinning weights through the lens of convex duality.

A Non‐Parametric Framework for Correlation Functions on Product Metric Spaces

International Statistical Review, EarlyView.
Summary We propose a non‐parametric framework for analysing data defined over products of metric spaces, a versatile class encountered in various fields. This framework accommodates non‐stationarity and seasonality and is applicable to both local and global domains, such as the Earth's surface, as well as domains evolving over linear time or time ...

A minimax principle, index of the critical point, and existence of sign-changing solutions to elliptic boundary value problems

Electronic Journal of Differential Equations, 1998
Summary: We apply the minmax principle we developed in [\textit{A. Castro, J. Cossio} and \textit{J. M. Neuberger}, Rocky Mt. J. Math. 27, No. 4, 1041-1053 (1997)]\ to obtain sign-changing solutions for superlinear and asymptotically linear Dirichlet problems. We prove that, when isolated, the local degree of any solution given by this minmax principle

A Note on Local Polynomial Regression for Time Series in Banach Spaces

Journal of Time Series Analysis, EarlyView.
ABSTRACT This work extends local polynomial regression to Banach space‐valued time series for estimating smoothly varying means and their derivatives in non‐stationary data. The asymptotic properties of both the standard and bias‐reduced Jackknife estimators are analyzed under mild moment conditions, establishing their convergence rates.

Some properties of Palais-Smale sequences with applications to elliptic boundary-value problems

Electronic Journal of Differential Equations, 1999
When using calculus of variations to study nonlinear elliptic boundary-value problems on unbounded domains, the Palais-Smale condition is not always satisfied.

Testing Distributional Granger Causality With Entropic Optimal Transport

Journal of Time Series Analysis, EarlyView.
ABSTRACT We develop a novel nonparametric test for Granger causality in distribution based on entropic optimal transport. Unlike classical mean‐based approaches, the proposed method directly compares the full conditional distributions of a response variable with and without the history of a candidate predictor.

When Greenwashing Exploits Consumer Heuristics: Information Overload, Bounded Rationality, and Implications for Consumer Protection

Journal of Consumer Affairs, Volume 60, Issue 3, Fall 2026.
ABSTRACT Greenwashing persists not only because firms are motivated to inflate their sustainability claims but also because consumers, limited by bounded rationality, depend on heuristics when overwhelmed with information. This conceptual article uses behavioral economics to connect specific types of greenwashing and greenhushing to affect ...

Adaptive Estimation for Weakly Dependent Functional Times Series

Journal of Time Series Analysis, Volume 47, Issue 5, Page 1013-1027, September 2026.
ABSTRACT We propose adaptive mean and autocovariance function estimators for stationary functional time series under 𝕃p−m‐approximability assumptions. These estimators are designed to adapt to the regularity of the curves and to accommodate both sparse and dense data designs.
