Probability Seminar by Eviatar Procaccia, 12/03/26, at Milano-Bicocca
by Tal Orenshtein 10 Mar '26

10 Mar '26

Dear all, I am pleased to announce a seminar talk by *Eviatar Procaccia* at the Department of Mathematics and Applications of the University of *Milano-Bicocca *on Thursday, March 12 at 15:30. Below you can find the details. Best regards, Tal Orenshtein ---------------------------- *Time and place: *Thursday, March 12, 2026 at 15:30, Room U9/08 (Edificio U9, viale dell'Innovazione 10) *Speaker:* *Eviatar Procaccia* (Technion – Israel Institute of Technology) *Title:* The Pool Model: a rotationally symmetric, mass-preserving MDLA variant *Abstract:* Multi-particle diffusion-limited aggregation (MDLA) describes the growth of an aggregate driven by a cloud of diffusing particles. Classic works of Kesten, Rath, Sidoravicius, Stauffer, and Sly show that in the high-intensity regime the MDLA aggregate grows linearly in time, while the low-intensity regime remains largely open. We introduce the pool model, a rotationally symmetric analogue in which particles (“droplets”) perform continuous-time random walks and are absorbed upon entering a circular pool initially centered at the origin. Each absorbed particle increases the pool’s mass, and the pool expands so that its area grows accordingly—yielding a natural mass-preserving dynamics. The imposed rotational symmetry makes the model more tractable for rigorous analysis, while retaining key features of MDLA. In this talk we focus on the critical density separating finite growth from explosive behavior, and we present rigorous bounds on the pool’s growth rate at and near criticality.

Seminario del Prof. Georgiou a Roma, Sapienza
by Enrico Scalas 10 Mar '26

10 Mar '26

Buongiorno, se avete perduto il seminario di Napoli di Nicos Georgiou, c'è la possibilità di seguirlo a Roma dopodomani. Infatti, il 12 marzo 2026, in aula 34 del Dipartimento di Scienze Statistiche, Sapienza Università di Roma, a partire dalle ore 14, il Prof. Nicos Georgiou, University of Sussex, UK, terrà un seminario dal titolo: Mean-field limit and parameter estimation for contagion dynamics on higher-order structures Classical models of contagion epidemics have graph based representations where the nodes represent the population and infections occur from an infected individual to a susceptible individual via a network link between them. At the same time, healing mechanisms try to fight the epidemic at node level. The simple descriptions of these representations also underscore their limitations, since the propagation of contagions in complex systems often involves repeated or simultaneous stimuli that individuals receive from their social contacts (such as their work or household). One may mechanistically encode these non-linear effects into contagion models by considering interactions that go beyond simple pairwise connections, by using hypergraphs rather than graphs. In this talk we will see the role higher-order interactions can play in the behaviour of the model when a rigorous mean-field can be obtained. Furthermore, we will discuss some inference techniques for the parameters of the epidemic (rates of infection) when only partial information on the type of infection is available and with only a single realisation of the epidemic curve as a datum. Tutte le persone interessate sono invitate a partecipare. Enrico Scalas

special session at SIEDS 2026, Catania
by Luca Martino 10 Mar '26

10 Mar '26

Dear all, I am sending below the call for the special session “Automatic Machine Judgment - Rethinking Evaluation in Academic Careers” (SIEDS 2026, Catania) and would appreciate it if you could share it with potentially interested colleagues. BR, Luca Martino (luca.martino(a)unict.it) -------------------------------------------------------------- TITLE of the special session: Automatic Machine Judgment - Rethinking Evaluation in Academic Careers Conference: LXII Riunione scientifica Società Italiana di Economia Demografia e Statistica (SIEDS 2026) https://www.sieds.it/index.php/page-presentazione/ PLACE AND DATES: Catania, 27-29 maggio 2026 Paper abstracts until 10 April 2026: https://www.sieds.it/index.php/page-call-for-papers/ https://www.sieds.it/wp-content/uploads/2026/02/Istruzioni-per-sottomettere… Special session The increasing reliance on quantitative indicators - such as citation counts, h-index, journal impact factors, and composite researcher scores - has transformed how academic merit is defined, measured, and rewarded. At the same time, universities and funding agencies are progressively incorporating algorithmic tools and automated decision-support systems into processes governing hiring, promotion, tenure, and grant allocation. These developments raise fundamental questions about meritocracy, transparency, and fairness in research evaluation. High-profile ranking exercises - such as the widely circulated “2% scientists” list produced by researchers at Stanford University - illustrate how composite bibliometric indicators can shape reputations, institutional strategies, and individual career trajectories on a global scale, often without clear public understanding of their methodological assumptions or limitations We invite contributions that critically examine those points. The session is organized by Prof. Luca Martino (luca.martino(a)unict.it) in collaboration with the Association “Trasparenza e Merito” (*https://www.trasparenzaemerito.org/ <https://www.trasparenzaemerito.org/>*). By bringing together scholars in scientometrics, research policy, sociology of science, and higher-education governance, this session aims to foster interdisciplinary dialogue on how evaluation systems shape academic behavior and institutional priorities. Interested participants are invited to submit an abstract by 10 April 2026 and to send (possibly) it via email to luca.martino(a)unict.it

Seminar of Maria Elvira Mancino @Tor Vergata
by Davide Pirino 09 Mar '26

09 Mar '26

Dear Colleagues, We are pleased to announce the seminar by *Maria Elvira Mancino (University of Florence)* at the University of Rome Tor Vergata. *When: *Wednesday, 11 March at 1:00 pm *Where:* University of Rome Tor Vergata, Department of Economics and Finance *Room:* Building B, 2nd Floor, Sala del Consiglio *Title: * *Honey BEE VOLatility: An environmental index for assessing climatic risk impact on ecosystems service provision* *Abstract: *This study investigates the impact of high-frequency climate risk, specifically temperature volatility, on honey bee production. Recognizing the crucial role of honey bees as environmental sentinels and their sensitivity to climatic variables, the research extends beyond conventional analyses of long-term average temperatures to explore the effects of short-term temperature "surprises." Using high-frequency, irregularly spaced data from thousands of Italian beehives (2019-2024), combined with external temperature data, a non-parametric estimation of weekly integrated volatility is provided. The results highlight that beehives in areas with lower biodiversity and higher pollution are more susceptible to high-frequency temperature volatility, whereas those in richer, cleaner environments show greater resilience. This underscores the critical importance of local environmental quality in mediating the impacts of climate risk on honey bee health and production. Everyone is welcome to attend.

We are pleased to announce two seminars by Daniel Ahlberg (Stockholm University) in Como and Milano. Wednesday, 18 March at 14:30 – Università dell'Insubria Title: Random perturbations of Euclidean geometry Room VS8.A (Torre di Via Valleggio 11, Como) Streaming (TEAMS): link <https://teams.microsoft.com/meet/32336493339992?p=OGABFTFErevQVUAOiT> Thursday, 19 March at 14:30 – Università di Milano-Bicocca Title: Noise sensitivity in spatial growth Room U9-08 (Building U9, Viale dell'Innovazione 10, Milano) Streaming (WEBEX): link <https://unimib.webex.com/unimib-it/j.php?MTID=mc1585e72e7593a9d9f0a3145116c…> The abstracts follow below. All interested participants are welcome. Best regards, Francesco Caravenna (with Giovanni Bazzoni and Davide Bignamini) %%%%%%%%%%%%%%%%%%%%%%%%%% Abstract (Como). Various probabilistic models for spatial growth can be thought of as random perturbations of Euclidean geometry. These models exhibit complex phenomena which are usually associated to critical behaviour, which is of central interest in contemporary probability theory. We will in this talk describe some of these phenomena, and relate their occurrence to the nature of Euclidean geometry. Abstract (Milano). The study of noise sensitivity of Boolean functions and percolation was initiated in a seminal paper of Benjamini, Kalai and Schramm in 1999. While subsequent studies have revealed fascinating phenomena in the context of percolation, few results have so far been obtained regarding other random spatial processes. We will in this talk present the first results of noise sensitivity for a growth process associated to the KPZ universality class. %%%%%%%%%%%%%%%%%%%%%%%%%% -- __________________________________ Francesco Caravenna Dipartimento di Matematica e Applicazioni Università degli Studi di Milano-Bicocca https://fcaraven.github.io/ __________________________________
