The Magnetized Electron Gas in terms of Hurwitz Zeta Functions

, 2001
We obtain explicit expressions for thermodynamic quantities of a relativistic degenerate free electron gas in a magnetic field in terms of Hurwitz Zeta functions. The formulation allows for systematic expansion in all regimes.

Cyber‐Resilient MMC‐MTDC Stability via Robust Observer Design for Wind‐Integrated Grids

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper proposes a stochastic stabilising control method, based on a Markov jump model (MJM), to comprehensively address stability challenges in modular multilevel converter‐based multi‐terminal direct current (MMC‐MTDC) systems due to communication network disturbances.

How Does Reverse‐Conformity Ambivalent Psychology Influence Rumor Spreading?

Discrete Dynamics in Nature and Society, Volume 2026, Issue 1, 2026.
In the age of social media, rumor dissemination brings serious negative impacts to society. It is important to explore the dissemination mechanism and management strategies to control rumor dissemination and reduce negative impacts. Considering the effect of reverse‐conformity ambivalent psychology on the rumor dissemination process, a novel dynamic ...

A perturbative approach to the spectral zeta functions of strings, drums and quantum billiards

, 2012
We have obtained an explicit expression for the spectral zeta functions and for the heat kernel of strings, drums and quantum billiards working to third order in perturbation theory, using a generalization of the binomial theorem to operators.

The Effects of Fluctuating Carrying Capacity on the Dynamics of a Holling‐Type III Predator–Prey Model

Journal of Mathematics, Volume 2026, Issue 1, 2026.
This study investigates the complex dynamics of a predator–prey system governed by the classical Lotka–Volterra model incorporating a Holling‐type III. To capture environmental variability, the prey’s carrying capacity is modeled as a periodic function, introducing a time‐dependent forcing into the system.

Modeling Prey–Predator Populations With Noise Following the Extended Gaussian Distribution

Journal of Probability and Statistics, Volume 2026, Issue 1, 2026.
This study examines how tourism influences the ecological balance of a protected natural park where two interacting wildlife species follow Lotka–Volterra‐type prey–predator dynamics. Tourists’ decisions to visit the park depend on environmental fluctuations, species visibility, and time‐varying preferences toward prey and predator populations.

Numerical Stability of Soil‐Water Coupled Analysis With Implicit Time Integration Using Spectral Radius of Recursive Equation Comprising Discretized Governing Equation of u‐p Formulation

International Journal for Numerical Methods in Engineering, Volume 126, Issue 21, 15 November 2025.
ABSTRACT The numerical stability of the u‐p formulation‐based dynamic soil‐water coupled analysis was evaluated using the spectral radius of a simultaneous recursive equation derived from the spatiotemporally discretized governing equations and time‐integration formulas.

Self‐Potential Signal Associated With Hydrothermal System Disrupted by Extreme Raining Events; The Case Study of Formica Leo, Piton de la Fournaise, La Réunion Island

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 11, November 2025.
Abstract The scoria cones called Formica Leo located at the base of the Piton de la Fournaise terminal cone have been chosen for its significant positive Self‐Potential (SP) anomalies associated with hydrothermal uprising fluids to monitor SP signal and study its dynamics in relation with huge and extreme rainfall events.

Joint approximation of analytic functions by shifts of the Riemann and periodic Hurwitz zeta-functions

Applicable Analysis and Discrete Mathematics, 2018
We present some new results on the simultaneous approximation with given accuracy, uniformly on compact subsets of the critical strip, of a collection of analytic functions by discrete shifts of the Riemann and periodic Hurwitz zeta-functions. We prove that the set of such shifts has a positive lower density.
