    Type-dependent stochastic Ising model describing the dynamics of a non-symmetric feedback module by Manuel González-Navarrete

    Published 2016-06-01
    “…We study an alternative approach to model the dynamical behaviors of biological feedback loop, that is, a type-dependent spin system, this class of stochastic models was introduced by Fernández et. al [13], and are useful since take account to inherent variability of gene expression.We analyze a non-symmetric feedback module being an extension for the repressilator, the first synthetic biological oscillator, invented by Elowitz and Leibler [7]. …”

    Published 2018-01-01
    “…Assuming that the averaged dynamical system is the classic Holling type II population model with asymptotically stable limit cycle, we prove that the dynamics of stochastic model may be approximated with a two-dimensional Gaussian Markov process with unboundedly increasing variances.…”

    Threshold dynamics of stochastic SIRSW infectious disease model with multiparameter perturbation by Zhengwen Yin, Yuanshun Tan

    Published 2024-11-01
    “…Subsequently, we obtained the asymptotic stability of both the disease-free equilibrium and the endemic equilibrium of the deterministic model corresponding to the stochastic model through stochastic stability theory. The results indicated that high-intensity noise perturbation can inhibit the spread of the disease, and the dynamic behavior of the disease transitioned from persistence to extinction as noise intensity increased. …”

    On a Stochastic Approach to Extensions of the Susceptible-Infected-Susceptible (SIS) Model Applied to Malaria by Abdoul Karim Drabo, Frédéric Bere, S. P. Clovis Nitiema

    Published 2024-01-01
    “…This work presents a stochastic model of malaria spread. We first calculated the basic reproduction number R0 of the models ShIhRhSh‐SvIv and ShLhIhRhSh‐SvLvIv in order to show that the malaria-free equilibrium is asymptotically stable; then, we used a finite Markov chain model to describe the interactions between the different compartments of the model SeLeIeReSe‐SaLaIaRaSa‐SvIv. …”

    Comparison between stochastic and deterministic selection-mutation models by Azmy S. Ackleh, Shuhua Hu

    Published 2007-01-01
    “…We show numerically that the mean behavior ofthe stochastic model in general agrees with the deterministic one.However, unlike the deterministic one, if the differences in thegrowth-to-mortality ratios are small in the pure selection case,it cannot be determined a priori which subpopulation will have thehighest probability of surviving and winning the competition.…”

    Gauss-diffusion processes for modeling the dynamics of a couple of interacting neurons by Aniello Buonocore, Luigia Caputo, Enrica Pirozzi, Maria Francesca Carfora

    Published 2013-09-01
    “…With the aim to describe the interaction between a couple of neurons a stochastic model is proposed and formalized. In such a model, maintaining statements of the Leaky Integrate-and-Fire framework, we include a random component in the synaptic current, whose role is to modify the equilibrium point of the membrane potential of one of the two neurons and when a spike of the other one occurs it is turned on. …”

    Published 2017-01-01
    “…To reduce this complexity, for a conceptual stochastic model we have explored how to take advantage of the system intrinsic multiscale structure: one might describe the stochastic dynamics of the cells at the vessel tip at their natural microscale, whereas the dynamics of the underlying fields is given by a deterministic mean field approximation obtained by an averaging at a suitable mesoscale. …”

    A Semiempirical MIMO Channel Model in Obstructed Viaduct Scenarios on High-Speed Railway by Tao Zhou, Cheng Tao, Liu Liu, Zhenhui Tan

    Published 2014-01-01
    “…The proposed MIMO model is based on the combination of realistic single-input single-output (SISO) channel measurement results and a theoretical geometry-based stochastic model (GBSM). Temporal fading characteristics involving K-factor and Doppler power spectral density (PSD) are derived from the wideband measurement under an obstructed viaduct on Zhengzhou-Xi’an HSR in China. …”

    Anti-correlation of LacI association and dissociation rates observed in living cells by Vinodh Kandavalli, Spartak Zikrin, Johan Elf, Daniel Jones

    Published 2025-01-01
    “…Here, we systematically test this assumption using cell-to-cell variability in gene expression as a window into the in vivo association and dissociation kinetics of the model transcription factor LacI. Using a stochastic model of the relationship between gene expression variability and binding kinetics, we performed single-cell gene expression measurements to infer association and dissociation rates for a set of 35 different LacI binding sites. …”
