Random Chemostats with Competition and Different Kinetics to Investigate the Growth of the Gut Microbiome

open access: yesMathematical Methods in the Applied Sciences, Volume 49, Issue 11, Page 12102-12115, 30 July 2026.
ABSTRACT We investigate some chemostat models incorporating wall growth, competition, random fluctuations on the dilution rate, and different consumption functions (Monod and Haldane). We analyze the asymptotic behavior of the solutions of the corresponding random differential systems to establish conditions on the model parameters under which the ...

Inference on a Stochastic Bass Model for New Product Adoption

open access: yesApplied Stochastic Models in Business and Industry, Volume 42, Issue 4, July/August 2026.
ABSTRACT This paper investigates stochastic versions of the classical Bass diffusion model, with a focus on the development and comparison of parameter estimation procedures. Two stochastic processes that generalize the classical Bass model, which is commonly used to describe sales dynamics in emerging markets, are considered.

Multimode Phonon Lasing via Self‐Induced Optical Coherent Pumping

open access: yesLaser &Photonics Reviews, Volume 20, Issue 13, 8 July 2026.
A silicon optomechanical nanobeam generates self‐sustained phonon lasing in multiple competing mechanical modes via self‐pulsing, an intrinsic optical modulation arising from cavity nonlinearity. This self‐organized mechanism enables robust multi‐frequency operation spanning periodic, quasi‐periodic, and chaotic regimes without external modulation. The

Numerical Approach of a Porous Thermoelastic Problem With Microtemperatures and Fading Memory

open access: yesZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 7, July 2026.
ABSTRACT In this work, we study, from the numerical point of view, a porous thermoelastic problem with microtemperatures, where the thermal evolution is influenced by the history of both the temperature and microtemperatures. This leads to a coupled system of partial integro‐differential equations.

Assessing the quality of random number generators through neural networks

open access: yesMachine Learning: Science and Technology
In this paper we address the use of Neural Networks (NNs) for the assessment of the quality and hence safety of several Random Number Generators (RNGs), focusing both on the vulnerability of classical Pseudo Random Number Generators (PRNGs), such as ...

Soil Microbial Diversity and Network Organization Respond to Land Use and Agricultural Inputs Worldwide

open access: yesGlobal Change Biology, Volume 32, Issue 7, July 2026.
Based on a global analysis of 1921 soil samples, we show that agricultural management acts as a powerful ecological filter reshaping microbial communities. Land use and inputs—pesticides and fertilizers—drive a functional shift toward opportunistic pathogens and fragmented, less connected microbial networks, potentially compromising soil ecosystem ...

Inverse problems of polynomial and rational matrices involving the eigenstructure and data of the column and row spaces

open access: yesJournal of the London Mathematical Society, Volume 114, Issue 1, July 2026.
Abstract The eigenstructure of a rational matrix is comprised by its invariant rational functions, both finite and at infinity, and by the minimal indices of its left and right null spaces. These quantities arise in many applications and have been thoroughly studied in numerous references.
