Finite‐Time Protocols Stabilize Charging in Noisy Ising Quantum Batteries

Advanced Quantum Technologies, Volume 9, Issue 9, September 2026.
A transverse‐field quantum Ising chain is charged as a quantum battery using finite‐time ramps, which suppress energy oscillations and stabilize charging compared to sudden quenches. When time‐correlated noise is introduced, the outcome depends entirely on the protocol: noise can either boost stored energy or improve efficiency, never both ...

An application of Ornstein-Uhlenbeck process to commodity pricing in Thailand

Advances in Difference Equations, 2017
In this paper, we examine an application of Ornstein-Uhlenbeck process to commodity pricing in Thailand. Prices of Tapioca Starch, Ribbed Smoke Sheet no. 3, and Thai Hom Mali Rice are investigated. We use three parameter estimation methods: least squares

An efficient Bayesian phylogenetic approach for joint inference of continuous and discrete trait evolution under a state‐dependent Ornstein–Uhlenbeck model

Methods in Ecology and Evolution, Volume 17, Issue 9, Page 2629-2644, September 2026.
Abstract Macroevolutionary adaptation of a continuous trait to different discrete states across species can be modelled using a phylogenetic state‐dependent Ornstein–Uhlenbeck (OU) process. Existing inference methods face two challenges. First, although efficient likelihood algorithms for continuous trait evolution models exist, none have been ...

Successful phased‐release reintegration of captive‐origin cheetah for metapopulation supplementation

Conservation Science and Practice, Volume 8, Issue 9, September 2026.
Conservation programs increasingly require consideration of rehabilitated individuals for translocations to reduce pressure on highly threatened wild populations. This case‐study evaluates the short‐term translocation success of captive‐origin cheetah (Acinonyx jubatus) after phased‐release reintegration into the wild in South Africa.

Random attractors for stochastic lattice reversible Gray-Scott systems with additive noise

Electronic Journal of Differential Equations, 2015
In this article, we prove the existence of a random attractor of the stochastic three-component reversible Gray-Scott system on infinite lattice with additive noise.

Time Scale Transformation in Bivariate Pearson Diffusions: A Shift from Light to Heavy Tails

Axioms
Heavy-tailed Pearson diffusions provide a natural alternative to well-known Ornstein–Uhlenbeck and Cox–Ingersoll–Ross processes in applications that require addressing heavy-tailed behavior.

Asymptotic Exponential Arbitrage in the Schwartz Commodity Futures Model

International Journal of Mathematics and Mathematical Sciences, 2019
In this paper, we consider the Schwartz’s one-factor model for a storable commodity and a futures contract on that commodity. We introduce the analysis of asymptotic arbitrage in storable commodity models by proving that the futures prices process allows

The Role of the Southeastern European Mountains as Cradles and Corridors of European Biodiversity: Insights From Agelenid Spiders

Journal of Biogeography, Volume 53, Issue 9, September 2026.
ABSTRACT Aim The Southeastern European Mountain System (SEEMS) is a well‐known glacial refugium for European fauna. Bridging the Mediterranean and Caucasus biodiversity hotspots, it is a melting point for diverse faunal elements, but also a center of origin and subsequent dispersal of a unique component of European biodiversity.

Likelihood Estimation for Stochastic Differential Equations with Mixed Effects

Scandinavian Journal of Statistics, Volume 53, Issue 3, Page 1061-1080, September 2026.
ABSTRACT Stochastic differential equations provide a powerful tool for modelling dynamic phenomena affected by random noise. When time series are observed for several experimental units, it is often the case that some of the parameters vary between the individual experimental units.

Stochastic Modeling of Adaptive Trait Evolution in Phylogenetics: A Polynomial Regression and Approximate Bayesian Computation Approach

Mathematics
In nature, closely related species often exhibit diverse characteristics, challenging simplistic line interpretations of trait evolution. For these species, the evolutionary dynamics of one trait may differ markedly from another, with some traits ...
