Published: July 2024

AI Article Synopsis

  • The proposed model is a unified stochastic SIR (Susceptible, Infected, Recovered) framework influenced by Lévy noise, incorporating various factors like time dependence, nonlinearity, and environmental changes.
  • It offers clear findings on the existence and uniqueness of solutions, focusing on the conditions for disease extinction versus persistence in the population.
  • The study includes practical examples and simulations to demonstrate and reinforce the key findings of the model.

Article Abstract

We propose a unified stochastic SIR model driven by Lévy noise. The model is structural enough to allow for time-dependency, nonlinearity, discontinuity, demography, and environmental disturbances. We present concise results on the existence and uniqueness of positive global solutions and investigate the extinction and persistence of the novel model. Examples and simulations are provided to illustrate the main results.

Article Synopsis
  • - Transcription occurs in bursts, with gene promoters toggling between active and inactive states, and enhancers play a crucial role by affecting how often, how long, and how intensely these bursts happen in animal development.
  • - Research shows that various enhancers can produce different levels of transcription using similar burst-control techniques, including increasing burst frequency and amplitude while keeping duration steady.
  • - A study comparing transcription patterns in natural and artificial contexts revealed that enhancers maintain consistent bursting strategies, suggesting a shared molecular mechanism influencing these patterns across different regulatory environments.

Many integrable stochastic particle systems in one space dimension (such as TASEP-Totally Asymmetric Simple Exclusion Process-and its -deformation, the -TASEP) remain integrable if we equip each particle with its own speed parameter. In this work, we present intertwining relations between Markov transition operators of particle systems which differ by a permutation of the speed parameters. These relations generalize our previous works (Petrov and Saenz in Probab Theory Relat Fields 182:481-530, 2022), (Petrov in SIGMA 17(021):34, 2021), but here we employ a novel approach based on the Yang-Baxter equation for the higher spin stochastic six vertex model.

Long-living transients in ecological models: Recent progress, new challenges, and open questions.

Traditionally, mathematical models in ecology placed an emphasis on asymptotic, long-term dynamics. However, a large number of recent studies highlighted the importance of transient dynamics in ecological and eco-evolutionary systems, in particular 'long transients' that can last for hundreds of generations or even longer. Many models as well as empirical studies indicated that a system can function for a long time in a certain state or regime (a 'metastable regime') but later exhibits an abrupt transition to another regime not preceded by any parameter change (or following the change that occurred long before the transition).

Processes under reset, where realizations are interrupted according to some stochastic rule and restarted from the initial state, find broad application in modeling physical, chemical, and biological phenomena and in designing search strategies. While a wealth of theoretical results has been recently obtained, current derivations tend to focus on specific processes, obscuring the general principles and preventing broad applicability. We present a unified approach to those observables of stochastic processes under reset that take the form of averages of functionals depending on the most recent renewal period.

Molecular modeling of odd viscoelastic fluids.

Phys Rev E

October 2024

Institute of Theoretical Physics, Wrocław University of Science and Technology, 50-370 Wrocław, Poland.

Article Synopsis
  • - This study explores a microscopic model of active particles in a fluid, focusing on "odd viscoelasticity," which is a unique behavior of these particles.
  • - The particles are designed as "odd dumbbells," featuring robotic devices that respond to torque in a specific way.
  • - The research provides a theoretical framework for understanding these odd effects, confirming findings through both analytical calculations and molecular dynamics simulations.
