PhD position at Milano Bicocca
by Francesca Greselin 10 Oct '22

10 Oct '22

Partially rectifying a previous message: Good morning, Hope my email finds you well. We are hiring a *PhD position in Statistics at the University of Milano-Bicocca from December 2022* (session III, published on October 3,2022, with *deadline for application on October 17 *at noon). More information about the content of the research can be found below, and at the link https://en.unimib.it/education/postgraduates/doctoral-research-phd-programm… Best, Francesca Greselin <https://www.scopus.com/authid/detail.uri?authorId=25936155400> Department of Statistics and Quantitative Methods University of Milano-Bicocca *Title of the research* Statistical methodologies for the development of green and eco-sustainable cosmetic products from marine environmental DNA *Abstract * Sustainable Fashion, Luxury, and Design are currently key sectors of Milan's economy. There is an increasing interest in an ecological and digital transition within all economic sectors, and Milan Universities, together with many innovative firms, are heading such an effort, also in the cosmetics field. This research project aims to contribute to transforming the production and distribution processes within the area of cosmetics to reduce environmental impacts and foster the market transition. The research will have a first phase to perform market research on cosmetics and luxury, firstly on bibliographic sources, and successively integrating different sources of information obtained from public repositories and from specific analyses that can be conducted on web scraped data. The first part of the study aims to understand and assess customers' interest in green cosmetics for topical use and identify the specific features that could make a difference in market share. As a result, particular skills related to data collection through different sources, data cleaning, and data integration should be developed along with the research. It also involves the processing of a vast amount of data, therefore, a good familiarity with and/or predisposition to the use of big data is welcome and desirable. Research should be carried on to devise the key factors required by the market or beneficial to it, and to scrutinize appropriate models for economic forecasting. The second phase of the research will be carried out on experimental data originated by studying new products. Within a wise ecological transition, microplastics will be replaced with natural materials for cosmetic products. This transition will be performed in collaboration with the Bicocca Marhe center (located on Maldives island), where particular plant species are found, and great biodiversity is available for the purpose. The activities will be conducted under a surveillance protocol to monitor these marine species' conservation status and assess the impact of human activities, to protect important offshore marine sites. Experiments with new cosmetics will also originate from studies of the microbiota of the skin, and how it is altered and modified with newly developed products. New chemical formulas will be experimented to find alternatives to analog formulas used in valid but not green cosmetics, perfecting and optimizing existing molecules, and formulating them as better alternative products. Finally, the third part of the research will be devoted to providing indications for production and distribution processes that will agree with the project's overall purpose of sustainability. Possible research exchange visits are envisaged with other foreign universities currently involved in ongoing collaborations.

SPASS seminar: Wolfgang König (WIAS and TU Berlin), 11 October, 11:30
by Gianmarco Bet 06 Oct '22

06 Oct '22

Dear Colleagues, We would like to invite you to the following SPASS seminar, jointly organized by UniPi, SNS, UniFi and UniSi: The free energy of (a box version of) the interacting Bose gas Prof. Wolfgang König, WIAS and TU Berlin (abstract below) The seminar will take place on 11 October at 11:30 in Aula Tricerri, Dipartimento di Matematica e Informatica “Ulisse Dini”, Firenze, and streamed online here <https://www.google.com/url?q=https://meet.google.com/gji-phwo-vbg&source=gm…>. The organizers, A. Agazzi, G. Bet, A. Caraceni, F. Grotto, G. Zanco https://sites.google.com/unipi.it/spass <https://www.google.com/url?q=https://sites.google.com/unipi.it/spass&source…> -------------------------------------------- Abstract: The interacting quantum Bose gas is a random ensemble of many Brownian bridges (cycles) of various lengths with interactions between any pair of legs of the cycles. It is one of the standard mathematical models in which a proof for the famous Bose–Einstein condensation phase transition is sought for. We introduce a simplified version of the model in $Z^d$ instead of $R^d$ and with an organisation of the particles in deterministic boxes in- stead of Brownian cycles as the marks of a reference Poisson point process. We derive an explicit and interpretable variational formula in the thermody- namic limit for the canonical ensemble for any value of the particle density. In this formula, each of the microscopic particles and the macroscopic part of the configuration are seen explicitly (if they exist); the latter receives the interpretation of the condensate. The methods comprises a two step large- deviation approach for marked Poisson point processes and an explicit dis- tinction into microscopic and macroscopic marks. We discuss the conden- sate phase transition in terms of existence of minimizer. (based on joint works with Adams/Collevecchio (2011) and Collin/Jahnel (preprint 2022).) ---------------------------------------------------------------------- Gianmarco Bet (he/him) Senior researcher https://gianmarco.bet Phone: (+39) 055 2751491 Department of Mathematics and Informatics "U.

03 Oct '22

Buongiorno ricevo ed inoltro. Saluti Alessandra ---------- Forwarded message --------- From: Inhomegenous Random <inter(a)math.cnrs.fr> Date: Sat, 1 Oct 2022 at 22:44 Subject: January 24-25 IRS 2023 Conference Announcement To: <faggiona(a)mat.uniroma1.it> Dear Colleagues, This is the first announcement for the two-day conference on: INHOMOGENEOUS RANDOM SYSTEMS which will be held on Tuesday 24 and Wednesday 25 January 2023 at Institut Curie and Institut Henri Poincaré, Paris, and also on-line. You will find in attachment a PDF file of the announcement with the same informations as below which you may print and post up. Looking forward to meeting you in Paris, Giambattista Giacomin, Christian Maes, Ellen Saada. --------------------------------------------------------------------- INHOMOGENEOUS RANDOM SYSTEMS Systemes Aleatoires Inhomogenes January 24-25, 2023 Institut Curie & IHP (also online) 11-13, rue Pierre et Marie Curie, Paris The aim of this annual workshop is to bring together mathematicians and physicists working on disordered or random systems, and to discuss recent developments on themes of common interest. Each of the two days is devoted to a specific topic; the 2021 session is planned as follows. Tuesday 24 January: POINT PROCESSES AND STATISTICAL MECHANICS. Moderator: Alessandra Faggionato (Roma). Nontrivial geometrical patterns emerge in many areas of science and technology and a fundamental tool for their modeling is provided by point processes. Their zoology is very rich and a central role is played by the Poisson point process. The workshop aims at presenting recent results on point processes both of theoretical nature (analysis, geometry and probability) and more applied ones, notably in the direction of statistical mechanics and material science. There will also be a moment in memory of our friend and colleague Francis Comets. Speakers: Alessandra Faggionato (Roma), Antoine Gloria (Paris & Bruxelles), Frank den Hollander (Leiden), Martin Huesmann (Muenster), Sabine Jansen (Muenchen), Raphael Lachieze-Rey (Paris), Giovanni Peccati (Luxembourg). Wednesday 25 January: FREE PROBABILITY, BETWEEN MATHS AND PHYSICS. Moderator: Jorge Kurchan (Paris) Free probability is a flourishing field in probability theory. It deals with non-commutative random variables where one introduces the concept of "freeness" in analogy to "independence" of commuting random variables. On the mathematical side, it has given new tools and a deeper insight into, amongst others, the field of random matrices. On the physics side, it has recently appeared naturally in the context of quantum chaos, where all its implications have not yet been fully worked out. Speakers: Denis Bernard (Paris), Jean-Philippe Bouchaud (Paris), Laura Foini (Saclay), Alice Guionnet (Lyon), Frederic Patras (Nice), Marc Potters (Paris), Roland Speicher (Saarbrucken). --------------------- The conference and online participation are free and open to all.

LTI@UniTO Seminar F. De Jong (Tilburg University): October 3, 12.00
by Luca Regis 29 Sep '22

29 Sep '22

Dear colleagues, I am happy to forward you the information regarding the following seminar organized by LTI@UniTO. The seminar can also be attended via zoom at the following link: https://us02web.zoom.us/j/86733344211?pwd=UGNoUi9CNFM5bE5SNmNaeFR6bTJsQT09 Best regards, Luca Regis LTI@UniTO and Fondazione Collegio Carlo Alberto are pleased to invite you to the following seminar: October 3, 2022 | 12:00-13:00 “How do Funds Deviate from Benchmarks? Evidence from MSCI’s Inclusion of Chinese A-shares” (joint with Lennart Dekker and Jasmin Gider) Frank de Jong (Tilburg University) Abstract. An increasing amount of assets is managed by benchmark-tracking investment funds. This study investigates how benchmarking changes affect portfolio compositions in the cross-section of different investor types and stock characteristics. To that end, we exploit the phased introduction of Chinese A-shares to the MSCI Emerging Markets index, which was announced in June 2017 and implemented over the period from May 2018 to November 2019. This change presents a rare opportunity to estimate the impact of index changes and to shed light on cross-sectional implications. We document that particularly passive funds systematically deviate from the benchmark. Market capitalization, stock liquidity and stock volatility affect how benchmark changes translate to portfolio adjustments of mutual funds and ETFs. We then study how the changes in benchmark weights affect financial market outcomes, more specifically the comovement of returns. We find that these characteristics moderate the impact of benchmarking changes on financial market outcomes, suggesting that deviations from benchmarks matter.
