Buongiorno, Martedi' 4 marzo Claudio Landim terra' un seminario al Dipartimento di Matematica (Sapienza, Roma). sotto trovate i dettagli. cordiali saluti alessandra faggionato Martedi' 4 Marzo, Aula C (Dip. Matematica, Univ. Sapienza), ore 14:30 Speaker: C. Landim (IMPA Rio De Janeiro, CNRS Rouen) Title: Zero-temperature limit of the Kawasaki dynamics for the Ising lattice gas in a large two-dimensional torus Abstract: We consider the Kawasaki dynamics at inverse temperature $\beta$ for the Ising lattice gas on a two-dimensional square of length $2L+1$ with periodic boundary conditions. We assume that initially the particles form a square of length $n$, which may increase, as well as $L$, with $\beta$. We show that in a proper time scale $L^2\, \theta_\beta$ particles form almost always a square and that this square evolves as a Brownian motion when the temperature vanishes. -- Prof. Alessandra Faggionato Department of Mathematics University La Sapienza Piazzale A.

Colloquium Fabio Lucio Toninelli a Roma Tre

Mercoledi' 26 febbraio 2014 Ore 16:00, Aula F Dip. Matematica e Fisica Roma Tre EDIFICIO AULE LARGO SAN L. MURIALDO,1 Colloquium di Matematica Fabio Toninelli (Universita' di Lione) Random tilings, Glauber dynamics and macroscopic shapes I "piastrellamenti" (tiling) del piano sono un oggetto classico in meccanica statistica e combinatoria. Se le "piastrelle" sono a forma di losanga, si ha una corrispondenza esatta con le interfacce del modello di Ising 3-dimensionale a temperatura nulla. A ogni piastrellamento e' possibile associare una funzione di altezza (superficie discreta). E' ben noto [Cohn-Kenyon-Propp] che, se la taglia della regione U da piastrellare tende all'infinito, la funzione altezza associata a un piastrellamento scelto uniformemente tende verso una certa forma limite macroscopica che risolve una PDE ellittica non-lineare. Sull'insieme dei piastrellamenti si puo' definire una dinamica stocastica che corrisponde alla dinamica di Glauber a temperatura zero per il modello di Ising. Un problema classico e' quello di stimare il tempo (mixing time) che la dinamica richiede per raggiungere l'equilibrio (la misura uniforme). La congettura, basata sull'idea euristica che l'interfaccia evolve seguendo un'equazione di tipo "movimento per curvatura media", e' che il mixing time cresca essenzialmente come il quadrato del diametro della regione U. Il nostro risultato principale e' una prova di questa congettura, sotto l'ipotesi che la forma macroscopica non presenti singolarita'. Basato su lavori in collaborazione con P. Caputo, B. Laslier e F. Martinelli.

21 Feb '14

Buongiorno, volevamo informarti che anche quest'anno si ripeter? il workshop "Mercati Energetici e Metodi Quantitativi: un Ponte tra Universit? e Aziende". Trovi tutte le informazioni sul sito web http://www.unponte2014.stat.unipd.it/ Sono aperte le submission per gli speaker (accademici e professionisti provenienti da aziende) che desiderino presentare un talk. Inoltre, quest'anno abbiamo deciso di estendere l'iniziativa organizzando, nei due giorni precedenti la conferenza, quattro tutorial sui seguenti argomenti: - Introduzione ai mercati dell'energia e del gas - Rischio di credito e di controparte nei mercati energetici - Strumenti di analisi e di previsione per i mercati energetici. - Tecniche di gestione di portafoglio e di ottimizzazione: i contratti strutturati nei mercati dell'energia. Tutte le informazioni sui tutorial si trovano alla pagina http://events.math.unipd.it/memq2014/ In attesa di rincontrarci a Padova, porgiamo i nostri pi? Cordiali Saluti, gli Organizzatori Giorgia Callegaro Enrico Edoli Francesco Lisi Tiziano Vargiolu

University of Kent-PhD Scholarship

Con preghiera di diffusione. Aggiungo che la borsa partirebbe da Settembre 2014. Cordiali Saluti, Fabrizio Leisen Postgraduate Scholarship Non-parametric priors for Bayesian inference *University* *of* *Kent* School of Mathematics, Statistics and Actuarial Science *Project:** Non-parametric priors for Bayesian Inference* *Supervisor:** Fabrizio Leisen* The use of Bayesian non-parametric (BNP) priors in applied statistical modelling has become increasingly popular in the last few years. From the seminal paper of Ferguson (1973, Annals of Statistics), the Dirichlet Process and its extensions have been increasingly used to address inferential problems in many fields. Examples range from variable selection in genetics to linguistics, psychology, human learning, image segmentation and applications to the neurosciences. The project aims to introduce and/or investigate new Bayesian non-parametric priors that can be used to describe a wide spectrum of phenomena. Keywords include: - Dirichlet and Pitman Yor Processes - Vectors of Dependent random probability measures - Non-exchangeable species sampling sequences *The* *School* *of* *Mathematics,* *Statistics* *and* *Actuarial* *Science* The School offers a lively research culture with a thriving group of around 250 taught postgraduates students and almost 100 postgraduate students, postdoctoral researchers and academic staff. Kent is among the best research-intensive universities in the UK. In the 2008 Research Assessment Exercise (RAE), the university was ranked 24th out of 159 institutions for its world-leading research, with six of our subject areas (including statistics) in the top tennationwide. Details of the research undertaken by the School can be found at: http://www.kent.ac.uk/smsas/postgraduate/phd-applications.html *The* *funding* This scholarship is partially funded by the FP7 Marie Curie Career Integration Grant "Flexible Bayesian non-parametric priors" held by Fabrizio Leisen. The scholarship is offered at the standard UK Research Councils' rate (currently£13,863) and will cover the tuition fees for a period of 3.5 years subject to satisfactory progress at each review period. *Entry* *Requirements* All candidates must have an excellent academic track record in Mathematics or Statistics or related disciplines and hold a good Honours degree in a relevant subject or equivalent. A Masters qualification such as an MSc or MMath orresearch experience would be advantageous. *To* *apply* To apply complete the online application form available by clicking the *'Apply'* button below or by visiting: http://www.kent.ac.uk/studying/postgrad/apply/index.html and select School research Scholarship under `How are you intendingto fund your studies?' and mention this research project in the research proposal.

Avviso di seminario :: Mortera@DSS (Scienze Statistiche, Sapienza)

----------------------------------------------------------------------------- A v v i s o d i S e m i n a r i o ----------------------------------------------------------------------------- Venerdì 21 Febbraio, ore 11am ----------------------------------------------------------------------------- Stanza 34 Dipartimento di Scienze Statistiche Sapienza Università di Roma JULIA MORTERA (Fac. di Economia, Università degli Studi di Roma3) terrà un seminario dal titolo ANALYSIS OF FORENSIC DNA MIXTURES tutti gli interessati sono invitati a partecipare. ----------------------------------------------------------------------------- Maggiori informazioni sui seminari presso il DSS sono consultabili a quest'indirizzo: http://goo.gl/Y6OQYm Saluti Pierpaolo Brutti - Fulvio De Santis --- Summary DNA is now routinely used in criminal investigations and court cases, although DNA samples taken at crime scenes are of varying quality and therefore present challenging problems for their interpretation. We present a statistical model for the quantitative peak information obtained from an electropherogram (EPG) of a forensic DNA sample and illustrate its potential use for the analysis of criminal cases. In contrast to most previously used methods, we directly model the peak height information and incorporates important artefacts associated with the production of the EPG. Our model has a number of unknown parameters, and we show that these can be estimated by the method of maximum likelihood in the presence of multiple unknown contributors, and their approximate standard errors calculated; the computations exploit a Bayesian network representation of the model. A case example from a UK trial, as reported in the literature, is used to illustrate the efficacy and use of the model, both in finding likelihood ratios to quantify the strength of evidence, and in the deconvolution of mixtures for the purpose of finding likely profiles of one or more unknown contributors to a DNA sample. Our model is readily extended to simultaneous analysis of more than one mixture as illustrated in a case example. We show that combination of evidence from several samples may give an evidential strength close to that of a single source trace and thus modelling of peak height information provides for a potentially very efficient mixture analysis. Joint work with Robert Cowell, Therese Graversen and Steffen Lauritzen
