Predictability of Air Pollutants Based on Detrended Fluctuation Analysis: Ekibastuz Сoal-Mining Center in Northeastern Kazakhstan

Urban Science
Environmental comfort and air pollution are among the most important indicators for assessing the population’s quality of life in urban agglomerations. This study aims to explore long-term memory in air pollution time series by analyzing the dynamics of ...

A Novel Method for Control Performance Assessment with Fractional Order Signal Processing and Its Application to Semiconductor Manufacturing

Algorithms, 2018
The significant task for control performance assessment (CPA) is to review and evaluate the performance of the control system. The control system in the semiconductor industry exhibits a complex dynamic behavior, which is hard to analyze.

The interplay between landscape change and plasticity in habitat selection determines dispersal movements and settlement in small non‐flying vertebrates

Oikos, Volume 2026, Issue 5, May 2026.
The response of dispersers to landscape changes depends on both external environmental conditions and individual internal conditions, as well as movement and orientation abilities. Plasticity in habitat selection may also affect how individuals respond to landscape changes.

Retarding Sub- and Accelerating Super-Diffusion Governed by Distributed Order Fractional Diffusion Equations

, 2002
We propose diffusion-like equations with time and space fractional derivatives of the distributed order for the kinetic description of anomalous diffusion and relaxation phenomena, whose diffusion exponent varies with time and which, correspondingly, can

Riemann–Liouville fractional Brownian motion with random Hurst exponent

Chaos: An Interdisciplinary Journal of Nonlinear Science
We examine two stochastic processes with random parameters, which in their basic versions (i.e., when the parameters are fixed) are Gaussian and display long-range dependence and anomalous diffusion behavior, characterized by the Hurst exponent. Our motivation comes from biological experiments, which show that the basic models are inadequate for ...

Dual Use Research of Concern—The Necessity of Global Bioethics Engagement

Bioethics, Volume 40, Issue 4, Page 373-379, May 2026.
ABSTRACT Dual use research of concern (DURC) refers to research conducted for legitimate scientific purposes that could also be misused to pose a significant threat to public health and safety, agricultural crops and other plants, animals, the environment, or national security.
