BioInference 2023 - Oxford - 8-9 June 2023
by Massimiliano Tamborrino 17 Feb '23

17 Feb '23

Dear all, We are delighted to announce the 2nd BioInference conference (https://bioinference.github.io/2023<https://emea01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fbioinfer…>), taking place at the Doctoral Training Centre at the University of Oxford on the 8th-9th June 2023. Launched in 2022, BioInference aims to bring together researchers from across statistics and mathematical modelling who work with biological systems, and from all career stages, to foster discussions between the two communities and to prompt collaborations. The talks from the 1st BioInference conference are available via our public YouTube channel (shorturl.at/ekmqT<https://emea01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fshorturl.…>). The conference will combine contributed talks and poster sessions. We invite abstracts for oral / poster presentations on work either relating to statistical methods development (so long as those methods are applicable to biological systems) or on the application of statistical methods to solve biological problems. We are especially interested in presentations on biological problems where an inference solution has yet to be found (i.e. unsolved inference problems). Abstracts can be submitted via a Google form (shorturl.at/dfo68<https://emea01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fshorturl.…>) and the deadline is midday on the 16th March 2023. The conference organising committee is committed to ensuring fair participation of individuals across all career stages, genders, races and ethnicities, ages, geographic locations, and universities. Kind regards, The BioInference Organisers Ioana Bouros (Oxford); Fergus Cooper (Oxford); Richard Creswell (Oxford); Aden Forrow (Maine); Ben Lambert (Exeter); Chon Lok Lei (Macau); Massimiliano Tamborrino (Warwick); Tom Thorne (Surrey) ------ Dr. Massimiliano Tamborrino Associate Professor Department of Statistics University of Warwick https://warwick.ac.uk/tamborrino<https://emea01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwarwick.…>

PostDoc position on Physics-Informed Machine Learning at IDSIA USI-SUPSI
by Azzimonti Laura 15 Feb '23

15 Feb '23

The "Dalle Molle" Institute for Artificial Intelligence (IDSIA) in Lugano, Switzerland is looking for a PosDoc Researcher in physics-informed machine learning. The position is framed within the EU-funded project PRAESIIDIUM, in collaboration with an outstanding team of academic, medical and industrial partners from all over Europe. We will develop a prototype tool for real-time prediction of the pre-diabetic risk based on the integration of patient-specific mathematical models and a rich dataset of real-life data. The approach will rely on novel physics-informed machine learning (ML) techniques in order to overcome the limits of standard “black-box” ML practice, while reducing the computational time for simulating heavy numerical models and improving their prediction performances. *** About the position *** We look for candidates with a Ph.D. in mathematics, physics, engineering, computer science, or related areas. The ideal candidate should have a solid background in mathematical modelling, ordinary and partial differential equations, dynamical systems, machine learning and/or related fields, good programming skills in R and/or Python and a strong commitment to fulfill research objectives. We offer a fixed-term position (initially for two years, with intent of prolongation) with an attractive salary, in line with Swiss standards and the candidate’s experience. *** About the application *** The instructions for the application, and other details of the call, can be found at the following link: https://www.supsi.ch/home_en/supsi/lavora-con-noi/2023-04-02-bando1850 Deadline: 2nd April 2023 *** About IDSIA *** IDSIA is a world-class research institute on AI founded in 1988, affiliated with both Università della Svizzera Italiana (USI) and Scuola Universitaria Professionale della Svizzera Italiana (SUPSI). It counts more than 100 staff researchers and more than 40 Ph.D. students, active in the research areas of machine learning, optimisation and control, autonomous robotics, intelligent networked systems, geometric computing and vision, natural language processing and information retrieval. IDSIA is based in the beautiful city of Lugano (Canton Ticino, Switzerland), located at the new USI-SUPSI Campus Est of Viganello-Lugano, a few hundred meters from the city center and the lake of Lugano. ––––––––––––––––––––––––––––––– http://people.idsia.ch/~laura.azzimonti/

OWPS Tomorrow: Frank den Hollander and Elena Pulvirenti
by Alberto Chiarini 14 Feb '23

14 Feb '23

Dear all, A reminder that tomorrow (Wednesday), from 15:00 to 17:00 UTC, Frank den Hollander and Elena Pulvirenti will be speaking at the One World Probability Seminar. Titles, abstracts and the zoom link are below the signature and will also be posted on the website https://www.owprobability.org/one-world-probability-seminar. We kindly ask for your help to share this message within your community. Best wishes, Alberto Chiarini and Adrián González Casanova ---------------------- Speakers: Frank den Hollander (Leiden) and Elena Pulvirenti (Delft) Talk 1 : Metastability for the Widom-Rowlinson model: I. Planar discs. Abstract We define the static Widom-Rowlinson model on a two-dimensional finite torus. The energy of a particle configuration is determined by its halo, defined as the union of unit discs centred at the positions of the particles. We discuss the metastable behaviour of a dynamic version of the model, in which particles are randomly created and annihilated as if the outside of the torus were an infinite reservoir with a given chemical potential. We start with the empty torus and are interested in the first time when the torus is fully covered by unit discs. This can be viewed as the crossover time from a ‘gas phase’ to a ‘liquid phase’. We consider the metastable regime where the temperature is low and the chemical potential is supercritical. In order to achieve the transition from empty to full, the system needs to create a sufficiently large droplet, called critical droplet, which triggers the crossover. It turns out that the critical droplet is close to a disc of a certain deterministic radius, with a boundary that is random and consists of a large number of unit discs that stick out by a small distance. We show how an analysis of the surface fluctuations allows us to derive both a volume term and a surface term in the asymptotics of the average crossover time. Based on joint work with Sabine Jansen (Munich) and Roman Kotecký (Prague). Talk 2 : Metastability for the Widom-Rowlinson model: II. Grains of general shape. Abstract We investigate what happens when the planar discs are replaced by convex grains in arbitrary dimensions whose shape may be random. We identify the size and the shape of the critical droplet as a function of the shape distribution for the grains. We also identify the volume term in the asymptotics of the average crossover time. In addition, we speculate about the surface term, formulating a conjecture about what it should look like. There are various interesting subcases, showing that the shape of the grains has a rather delicate influence on the critical droplet and the average crossover time. Based on joint work with Yogesh Dhandapani (Bangalore) and Roman Kotecký (Prague).

Seminario di Luisa Andreis
by Lorenzo Taggi 14 Feb '23

14 Feb '23

Buongiorno, si trasmette il link per seguire il seminario di Luisa Andreis (Politecnico di Milano) tramite Zoom: https://uniroma1.zoom.us/j/84073069369 Martedì 14 Febbraio, ore 14:00 Sala di Consiglio, Dipartimento di Matematica, Sapienza Università di Roma *Title: *Rare events in sparse random graphs *Abstract:* Rare events for dense random graphs are well described using the theory of large deviations and graphons. When graphs are sparse the picture is less clear, objects that describe globally the graphs and their limits, as graphons do for dense graphs, have not been defined yet. Nevertheless we do have information on how these graphs look like when explored locally from a vertex and this, under some assumptions, gives also information on global properties. In this talk we will give an overview on what is known on rare events in this regime, focusing in particular on large deviation statements on connected components in inhomogeneous random graphs and on links with coagulation processes. This talk is based on joint works with Wolfgang König (WIAS and TU Berlin), Tejas Iyer, Heide Langhammer, Elena Magnanini and Robert Patterson (WIAS).
