R: R: Annuncio seminario Marta Sanz-Sole (fwd)
by Tiziano Vargiolu 13 Oct '20

13 Oct '20

---------- Forwarded message ---------- Date: Tue, 13 Oct 2020 09:57:12 +0000 From: michele giordano <g.michele(a)outlook.com> ------------------------- Dear all, This is an announcement of the: STAR Online Seminars. The seminar will be held on Friday 16. October from 11:00-12:00. You will recieve the link for the zoom room by registering for the seminar at the following link (https://nettskjema.no/a/159180) The lecture will last for 45 minutes + questions. This week's speaker is Marta Sanz-Sole from University of Barcelona, with the seminar: Stochastic wave equations with super-linear coefficients. Abstract: We consider a stochastic wave equation on $R^d , d \in {1, 2, 3}$, driven by a Gaussian noise in $(t, x)$, white in time. We assume that the free terms $b$ and $\sigma$ are such that, for $|x| \rightarrow \infty$, $|\sigma(x)| < \sigma_1 + \sigma_2|x| (\ln_+(|x|))^a , |b(x)| < \theta_1 + \theta_2|x| (\ln_+(|x|))^{\delta}$ , (1) where $\theta_2, \sigma_2 > 0, \delta , a > 0$, with $b$ dominating over $\sigma$. For any fixed time horizon $T > 0$ and with a suitable constraints on the parameters $a, \delta, \sigma_2$ and $\theta_2$, we prove existence of a random field solution to the equation and that this solution is unique, and bounded in time and in space a.s. The research is motivated by the article [R. Dalang, D. Khoshnevisan, T. Zhang, AoP, 2019] on a $1-d$ reaction-diffusion equation with coefficients satisfying conditions similar to (1). We see that the $L^\infty$- method used by these authors can be successfully implemented in the case of wave equations. This is joint work with A. Millet (U. Paris 1, Pantheon-Sorbonne). After the end of the seminar, you are invited to bring a cup of coffee or tea and have a chat in our ''Coffee in the Stars'' here you will have the chance to talk and interact with the other persons that attended the seminar, and have a digital "coffee break". We are looking forward to see you, online!

by Laura Maria Sangalli 12 Oct '20

12 Oct '20

Please see the following announcement of a junior researcher (RTDa) position opening in the group of Applied Statistics at the Department of Mathematics, Politecnico di Milano. ————————————————————————————————————————— Dear colleagues, I would like to announce a *junior researcher* (RTDa) position opening in the group of Applied Statistics at the Department of Mathematics, Politecnico di Milano. Please kindly forward the following announcement to potential candidates. Best regards, Francesca Ieva ————————————————————————————————————————— *Junior Researcher position in Statistics * *Project title*: "Integration between study design and data analytics for generating credible evidence in the field of healthcare from heterogeneous sources of structured and unstructured data” ====================================================================== We are looking for a junior researcher (3 year contract, starting date is between Feb 2021 - March 2021) to join the research group of Applied Statistics working within the research plan between Politecnico and AstraZeneca. One key criticism of evidence-based medicine is that only a minority of patients benefits of even efficacious therapies, but all treated patients are exposed to the costs and potential harms of those therapies. As a result, the effect of any treatment is often uncertain in a specific patient. Personalized care and precision medicine are becoming the main perspectives for obtaining better health outcomes at sustainable costs. The activities will develop along these perspectives with particular focus towards integrating observational designs and big data analytics to obtain solid, reproducible evidence whose results are verifiable in terms of health and expenditure. To this end, the researcher will develop multiple lines of research on Health Analytics for monitoring the effect of innovative oncological drugs through Real World Data, in collaboration with highly qualified clinical research centers. The ideal candidate should have a background and skills in at least some of the following: - Data Science, Statistics, Health Economics, Applied Mathematics, Software/Mathematical Engineering. - Solid experience in the data management and data analysis with R, Python, Matlab or C++. - Working knowledge in at least one of the following topics: biostatistics, pharmacoepidemiology, applied statistics, health economics. The effort is of a collaborative nature so strong interpersonal and communication skills are required. Teaching for both statistics and medical programs will be required. Working language is Italian and English. **Deadline for applications** is *November 11th, 2020*. Information and details about procedure can be found at https://www.polimi.it/it/docenti-e-staff/bandi-e-concorsi/bandi-e-concorsi-… For any further information please send an e-mail to francesca.ieva(a)polimi.it<mailto:francesca.ieva@polimi.it>. ----------------------------------------------------------------------------------------------------------------------------------------------- —— Laura Maria Sangalli MOX - Dipartimento di Matematica Politecnico di Milano Piazza Leonardo da Vinci 32 20133 Milano - Italy tel: +39 02 2399 4554 fax: +39 02 2399 4568 email: laura.sangalli(a)polimi.it<mailto:laura.sangalli@polimi.it> url: http://mox.polimi.it/~sangalli

Pisa Online Seminars - Mauro Mariani and Marielle Simon (Tuesday, Oct. 13 at 14:00 and 15:00)
by Giacomo Filippo Di Gesu 09 Oct '20

09 Oct '20

Dear colleagues, I would like to announce the following online seminar organized by the Probability group of the University of Pisa. The talks will be accessible under the link Join Microsoft Teams Meeting<https://teams.microsoft.com/l/meetup-join/19%3a17115d7f6ef44c5e91974362906c…> <https://aka.ms/JoinTeamsMeeting> Best regards, Giacomo <https://aka.ms/JoinTeamsMeeting> Tuesday, Oct. 13, 14:00 Speaker: Mauro Mariani Title: Quasi-invariant measures for a model of evolutionary biology Abstract: I will discuss a class of random models for the genetic evolution of a population of individuals with asexual reproduction. Formally, this is a diffusion process on an infinite-dimensional simplex. subject to absorption. It has been largely investigated in the past, both numerically and analytically as a model for the Muller's ratchet. We prove the existence and uniqueness of quasi-invariant measures describing the long-time behavior of the genetic distribution of the population, conditioned to non-extinction. The seminar is mostly based on https://arxiv.org/abs/2007.14715 Tuesday, Oct. 13, 15:00 Speaker: Marielle Simon Title: Hydrodynamic limit for a facilitated exclusion process Abstract: In this talk we will be interested in a one-dimensional exclusion process subject to strong kinetic constraints, which belongs to the class of cooperative kinetically constrained lattice gases. More precisely, its stochastic short range interaction exhibits a continuous phase transition to an absorbing state at a critical value of the particle density. We will see that the macroscopic behavior of this microscopic dynamics, under periodic boundary conditions and diffusive time scaling, is ruled by a non-linear PDE belonging to free boundary problems (or Stefan problems). One of the ingredients is to show that the system typically reaches an ergodic component in subdiffusive time. Based on joint works with O. Blondel, C. Erignoux and M. Sasada

Aggiornamento: il Seminario di Probabilita' di Roma Tre del 12-10-2020 (Thomas Finn) si terra' in modalita' Mista
by Alexandre Stauffer 09 Oct '20

SEMINARIO Probabilita' Thomas Finn (University of Bath) Titolo: Non-equilibrium multi-scale analysis and coexistence in competing first passage percolation Lunedi' 12 Ottobre 2020 ORE 14:00 Dipartimento di Matematica e Fisica Universita' degli Studi Roma Tre Largo San Leonardo Murialdo,1 - Pal.C - Aula 211 Abstract We consider a natural random growth process with competition on Z^d called first passage percolation in a hostile environment (FPPHE), in which two processes compete for the occupancy of sites. The first starts at the origin and spreads through the edges of Z^d at rate 1, while the second is initially dormant in seeds, which are distributed as a product of Bernoulli random variables of parameter p on Z^d, and grows from a seed at rate lambda>0 once either process attempts to occupy that seed. Depending on the value of p and lamba, the model observes a rich behaviour with multiple phase transitions. We prove that there is a coexistence phase in which both processes occupy a positive density of sites, which is a stark contrast to the behaviour of other competition models on Z^d. In studying FPPHE, we introduce a novel approach to multi-scale analysis that can be used to analyse processes with non-equilibrium dynamics. Indeed, FPPHE lacks both equilibrium dynamics and monotonicity (adding a seed could benefit the first process), preventing the use of a more standard multi-scale approach. In this talk, we outline our main results for FPPHE and provide an overview for how this new multi-scale approach can be applied. Il seminario si svolgera' in modalita' MISTA: IN PRESENZA: presso l'aula 211, palazzina C di Largo San Leonardo Murialdo 1. La capienza massima dell'aula e' di circa 10 persone; preghiamo chi intenda partecipare in presenza di scrivere un messaggio a astauffer(a)mat.uniroma3.it DA REMOTO: Per partecipare al seminario cliccare sul seguente link https://teams.microsoft.com/l/meetup-join/19%3ameeting_OTk4MzI5MzktY2EzNS00…
