APOLOGIES FOR CROSS-POSTING Dear Colleagues, The Journal Fractal and Fractional (ISSN 2504-3110) will publish the special issue "Stochastic Modeling in Biological System" https://www.mdpi.com/journal/fractalfract/special_issues/biological_system of which I am guest editor. The deadline for manuscript submissions is 15 November 2022. The aim of this Special Issue is to publish original research articles covering advances in the theory of stochastic modeling in biology. In this framework, continuous and discrete time stochastic processes will be discussed, as well as stochastic differential equations, fractional differential equations, correlated first-passage-time problems, stochastic optimal controls, parameter estimation, and simulation techniques. All the above topics are intended to be treated in the spirit of modeling the evolution of stochastic systems of interest in biology. Potential topics include but are not limited to the following: -Stochastic processes for neuronal activity; -Jump-diffusion processes; -First-passage-time problems; -Markov and semi-Markov processes; -Time-changed processes; -Markov chains; -Fractional processes; -Fractional Brownian motion. I hope that you will consider this special issue as an interesting and useful forum for publishing your latest research work in stochastic modeling in Biology. I would be glad if you will submit a paper to this special issue.

********************************************************************* SEMINARI DI PROBABILITA' E STATISTICA MATEMATICA DIPARTIMENTO DI MATEMATICA "G. PEANO" UNIVERSITA' DEGLI STUDI DI TORINO *con il supporto della fondazione CRT* ********************************************************************* https://sites.google.com/view/torinostochastics/seminar-series-on-data-scie… Nell'ambito delle attività seminariali del Dottorato in Modeling and Data Science, *Giovedì 24 Marzo 2022 alle ore 17:00* in Aula Magna presso il Dipartimento di Matematica "G. Peano" dell'Università degli Studi di Torino, Via Carlo Alberto 10, il Prof. *Giacomo Aletti* (Dipartimento di Scienze e Politiche Ambientali, Università degli studi di Milano) terrà un seminario dal titolo *Mathematical, numerical and statistical problems in the analysis of probabilistic counting of distinct elements* Abstract: Data streams are sequences of objects that cannot be available for random access but must be analyzed sequentially when they arrive and immediately discharged. One of the main applications in streaming algorithms concerns the problem of counting the number F0 of distinct elements in a stream, when the information that can be stored is of the order of the logarithm of the quantity of interest F0. In this seminar, the Flajolet-Martin class of probabilistic algorithms is analyzed from a probabilistic point of view, thus opening several computational, statistical, and mathematical problems. Connections with some consolidated theories will be shown. The results presented may be found in Aletti G. Analytical Confidence Intervals for the Number of Different Objects in Data Streams. Big Data Research, Volume 25, 2021 . Tutti gli interessati sono invitati a partecipare. E' possibile seguire il seminario on line su piattaforma WebEx. *Chi fosse interessato, può mandarmi una email e provvederò a inviare l'invito (con il link)* Cordiali saluti -- %------------------------------------------------------- Elvira Di Nardo Dept.

Seminar in Pisa: Langxuan Su
by Francesco Grotto 16 Mar '22

16 Mar '22

Dear Colleagues, we would like to invite you to the following seminar by Langxuan Su (Duke University) to be held next Wednesday in Pisa and online via Google Meets. The organizers, A. Agazzi and F. Grotto ------------------------------------------------------- Location: Sala Seminari, Dipartimento di Matematica, Pisa Google Meet Link: https://meet.google.com/gji-phwo-vbg Time: March 23, 2022, 15:00 CET Speaker: Langxuan Su (Duke University) Title: A Large Deviation Approach to Posterior Consistency in Dynamical Systems Abstract: We provide asymptotic results concerning (generalized) Bayesian inference for certain dynamical systems based on a large deviation approach. Given a sequence of observations, a class of parametrized model processes and a loss function, we specify the generalized posterior distribution. We state conditions on the model family and the loss function such that the posterior distribution converges. The two conditions we require are: (1) a conditional large deviation behavior for a single model process, and (2) an exponential continuity condition over the model family for the map from the parameter to the loss incurred between a model process and the observations. The proposed framework is quite general, we apply it to two very different classes of dynamical systems: continuous time hypermixing processes and Gibbs processes on shifts of finite type. We also show that the generalized posterior distribution concentrates asymptotically on those parameters that minimize the expected loss and a divergence term, hence proving posterior consistency.
