seminario di Maurizia Rossi a Pavia

18 Nov '14

Cari colleghi, vi annuncio che giovedì 27 novembre, alle ore 14:30 precise, nell'aula Beltrami del Dipartimento di Matematica dell'Universita' di Pavia, la Dott. Maurizia ROSSI (Università di Roma Tor Vergata) terra' un seminario dal titolo *"Quantitative Central Limit Theorems for Nonlinear Functionals of RandomEigenfunctions on $\mathbb S^d$, $d\ge 2$".* Distinti saluti, Raffaella Carbone ----------------- *ABSTRACT* *We investigate Stein-Malliavin approximations for nonlinear functionals of geometric interest for random eigenfunctions on the unit d-dimensional sphere Sd, d ≥ 2. All our results are established in the high energy limit, i.e. as the corresponding eigenvalues diverge. In particular, we prove a quantitative Central Limit Theorem for the ex- cursion volume of Gaussian eigenfunctions; this goal is achieved by means of several results of independent interest, concerning the asymptotic analysis for the variance of moments of Gaussian eigenfunctions, the rates of convergence in various probability metrics for Hermite subordinated processes, and quantitative Central Limit Theo- rems for arbitrary polynomials of finite order or general, square-integrable, nonlinear transforms. Some related issues were already considered in the literature for the 2- dimensional case S2; our results are new or improve the existing bounds even in this special circumstances. Proofs are based on the asymptotic analysis of moments of all order for Gegenbauer polynomials, and make extensive use of the recent literature on so-called fourth-moment theorems by Nourdin and Peccati. This talk is based on the paper Stein-Malliavin Approximations for Nonlinear Func- tionals of Random Eigenfunctions on Sd, joint work with Domenico Marinucci.----------------* Raffaella Carbone, PhD Ricercatore di Probabilità e Statistica Matematica Dipartimento di Matematica dell'Università degli Studi di Pavia

Con preghiera di diffusione tra tutti i possibili interessati, scusandomi per invii multipli. Cordialmente, Giacomo Aletti -------------- Nell'ambito dei Reading Group Seminars e del Seminario di Matematica Applicata, il giorno lunedì 24 Novembre 2014, alle ore 14.30, nell'Aula C del Dipartimento di Matematica dell'Universita' degli Studi di Milano, Via C. Saldini, 50, Milano, "Multispecies models for large neural network description" Anna CATTANI, Center for Neuroscience and Cognitive Systems (CNCS), IIT, Rovereto Joint work with Claudio Canuto Abstract: Today modeling large neural network is a topic more relevant than ever. In particular, the set up of computer simulations describing complex networks with a huge number of nodes is a formidable challenge. The intrinsic difficulties concerning the prohibitive computational costs may be handled to some extent by exploiting what we call "multispecies" models. From a mathematical perspective this issue consists in formalizing the PDE-based continuum models which describe the high-density populations inside the network and studying interactions between them and the ODE-based discrete models for each neuron belonging to the low-density populations. In particular, we exploit such an approach to describe the Golgi-Granular cell loop network in the Cerebellum. Each single cell is described by means of the FitzHugh-Nagumo model and both electrical and chemical (excitatory and inhibitory) synapses are taken into account. Several simulations describing interesting phenomena as synchronization and travelling waves have been done. Biological aspects have also been examined in order to provide our work with scientific completeness.

Bicocca Winter School on SINGULAR STOCHASTIC PDEs
by Francesco Caravenna 14 Nov '14

14 Nov '14

RECENT BREAKTHROUGHS IN SINGULAR STOCHASTIC PDEs Bicocca Winter School (2-6 February 2015) The aim of this school is to present some recent breakthroughs in the theory of non-linear stochastic PDEs, that allow to give a rigorous meaning to some important singular equations for which classical methods fail, due to the irregularity of the noise. Examples include the Kardar-Parisi-Zhang (KPZ) equation in 1d, the equation of stochastic quantization in 3d, the parabolic Anderson model in 2d. The school is mainly targeted at PhD students and young researchers. There will be two mini-courses by Massimiliano Gubinelli (Université Paris Dauphine) and Lorenzo Zambotti (Université Pierre et Marie Curie), presenting different approaches but discussing analogous examples. The venue of the school is the Department of Mathematics and Applications of the University of Milano-Bicocca.

de Finetti risk seminar - november 2014
by Emanuela Rosazza 12 Nov '14

12 Nov '14

On behalf of the Scientific Committee of the de Finetti Risk Seminars, we are glad to invite you to participate at the following Lectures at 16:30: Conditional systemic risk measures Thilo Meyer-Brandis (LMU Munich) ABSTRACT The financial crisis has demonstrated that systemic risk due to the interconnectedness of financial-market participants - such as financial institutions, insurers, governments and, even, regulators themselves - can dramatically amplify the consequences of isolated shocks to financial systems and pose a serious threat to prosperity and social stability.The traditional approach to risk control in financial mathematics is to apply risk measures to single institutions. However, this strategy fails to capture systemic risk because it treats institutions as if they were in isolation, and recent literature in financial mathematics has started to develop various approaches to rectify this deficiency. In this presentation we will axiomatically introduce and characterize risk-consistent conditional systemic risk measures. This class of conditional systemic risk measures is defined on multidimensional risks and consists of those conditional systemic risk measures which can be decomposed into a state-wise conditional aggregation and a univariate conditional risk measure. Our studies are based on the axiomatic characterization in [Chen et al., 2013] of a similar class of systemic risk measures in a finite state and unconditional framework. We argue in favor of a conditional framework on general probability spaces for assessing systemic risk. Moreover, we allow for very general aggregation rules, a less restrictive axiomatic setting, and thus a more flexible structure which covers many prominent examples of systemic risk measures from the literature and used in practice. Further, we will see how this type of systemic risk measures naturally arises when considering families of consistent conditional systemic risk measures and discuss some examples. at 18:00: Mathematical models for the formation of financial bubbles Francesca Biagini (LMU Munich) ABSTRACT The notion of an asset price bubble has two ingredients. One is the observed market price of a given financial asset, the other is the asset's intrinsic value, and the bubble is defined as the difference between the two. The intrinsic value, also called the fundamental value of the asset, is usually defined as the expected sum of future discounted dividends. In the first part of the talk we study a flow in the space of equivalent martingale measures and focus on the corresponding shifting perception of the fundamental value of a given asset in an incomplete financial marketmodel. This allows us to capture the birth of a perceived bubble and to describe it as an initial submartingale which then turns into a supermartingale before it falls back to its initial value zero. In the second part of the talk we examine the impact of overconfidence on bubbles formation in the framework of reduced-form models for credit risk. We assume that the wealth associated to a defaultable asset may be strongly affected by the trading activity of overconfident investors, who believe the asset to be safe and provoke an alteration of its estimated value. Since the value process changes under this influence, the underlying pricing measure has also to readapt determining a switch in the space of the equivalent martingale measures. In this way we provide a constructive approach to explain bubbles formation as well as motivate a dynamics in the space of equivalent martingale measures at micro-economic level. LOCATION: The seminar will be held on Wednesday, November 19, starting from 16.30, Aula di rappresentanza, Dept. of Mathematics, Milano University, Via C. Saldini 50, Milano. A refreshment will be offered at 17.30. Scientific Committee: Prof. Marco Frittelli (Univ. degli Studi di Milano) Prof. Fabio Maccheroni (Univ. Bocconi) Prof. Massimo Marinacci (Univ.

seminario di Alessandro Gnoatto presso Prometeia - Bologna
by Giacomo Scandolo 12 Nov '14

12 Nov '14

Il giorno Martedì 18 Novembre 2014, alle ore 14:30 presso la sede di Prometeia (sala grande, primo piano) via G.Marconi 43, Bologna Alessandro Gnoatto (Ludwig-Maximilians Universität München) terrà un seminario dal titolo "Interest rate modelling after the financial crisis" Abstract In the first part of the talk we proceed to review the main changes in the interbank interest rate market after the financial crisis. We present the most relevant empirical evidences: divergence between different interbank rates, failure of the standard FRA replication argument, emergence of basis swap spreads. Secondly, we quickly review the valuation of contingent claims under collateralization, which constitutes the market practice for interest rate products in the post-crisis world and forms the basis for multiple curve valuation. In the second part of the talk we propose a general framework for modelling multiple yield curves. In a general semimartingale setting, we provide an HJM approach to model the term structure of multiplicative spreads between FRA rates and simply compounded OIS risk-free forward rates. We derive an HJM drift and consistency condition ensuring absence of arbitrage and, in addition, we show how to construct models such that multiplicative spreads are greater than one and ordered with respect to the tenor's length. When the driving semimartingale is an affine process, we obtain a flexible and tractable Markovian structure. Finally, we show that the proposed framework allows to unify and extend several recent approaches to multiple yield curve modelling. The talk is based on joint works with C. Cuchiero, and C. Fontana.

Benoit Laslier (Cambridge) Titolo: Stochastic dynamics of discrete interfaces and dimer models. Mercoledi' 05 Novembre 2014 ORE 15:30 Dipartimento di Matematica e Fisica Universita' degli Studi Roma Tre AULA 311 (SEMINARI) Largo San L. Murialdo,1 Abstract We will study some effective models, called dimer models, for the interface between two coexisting thermodynamical phases in three dimension. We will show in a relatively general context that the time needed for the system to reach equilibrium is of order L^(2+o(1)), where L is the typical length scale of the system. The exponent 2 is optimal. More precisely, for surfaces attached to a curve drawn in some plane, we will control the mixing time for lozenge tilings and domino tilings (and a few other related models). For surfaces attached to a general curve, we will only work with lozenges and use a weaker notion of "macroscopic" convergence.

Seminario BESKOS

******************************************************************* STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO ******************************************************************* Venerdi' 7 Novembre 2014 alle ore 12:00, presso la sala rossa del Collegio Carlo Alberto, Moncalieri (TO), si terra' il seguente seminario: Alexandros BESKOS (University College London) SMC SAMPLERS FOR APPLICATIONS IN HIGH DIMENSIONS Abstract: Sequential Monte Carlo (SMC) methods are nowadays routinely applied in a variety of complex applications: hidden Markov models, dynamical systems, target tracking, control problems, just to name a few. Whereas SMC methods have been greatly refined in the last decades and are now much better understood, they are still known to suffer from the curse of dimensionality: algorithms can sometimes break down exponentially fast with the dimension of the state space. As a consequence, practitioners in high-dimensional Data Assimilation applications in atmospheric sciences, oceanography and elsewhere will typically use 3D-Var or Kalman-filter-type approximations that will provide biased estimates in the presence of non-linear model dynamics. The talk will concentrate on a class of SMC algorithms and will look at ways to reduce the cost of the algorithms as a function of the dimension of the state space. Explicit asymptotic results will clarify the effect of the dimension at the properties of the algorithm and could provide a platform for algorithmic optimisation in high dimensions. Applications will be shown in the context of Data Assimilation, in a problem where the objective is to target the posterior distribution of the initial condition of the Navier-Stokes equation given a Gaussian prior and noisy observations at different instances and locations of the spatial field. The dimension of the signal is in theory infinite-dimensional - in practice 64x64 or more depending on the resolution – thus posing great challenges for the development and efficiency of SMC methods. Tutti gli interessati sono invitati a partecipare. Il seminario e' organizzato dalla "de Castro" Statistics Initiative (http://www.carloalberto.org/stats) in collaborazione con il Collegio Carlo Alberto.

seminario Carlo Acerbi in Bicocca
by fabio.bellini 31 Oct '14

31 Oct '14

Il giorno lunedì 3 novembre alle ore 17, presso la Sala del Consiglio della Scuola di Economia e Statistica della Università di Milano Bicocca, al IV piano dell'edificio U7, il dott. Carlo Acerbi, Executive Director a MSCI, presenterà un seminario su: Supply-Demand Symmetry Abstract How does the order book look like in a market where there's perfect balance between supply and demand? The question is less obvious than it sounds, and still awaits formalization. The problem admits a clear formalization based on analogies with change of numeraire techniques. We characterize and classify symmetrical models. Supply-Demand symmetry turns out to be something different from just bid-ask parity of the market cost functions, and the two concepts are shown to coincide only in very liquid regimes. Tutti gli interessati sono invitati a partecipare. Fabio Bellini

We welcome both theoretical and applied original contributions. In this edition, we especially welcome papers connecting imprecise probabilities with related research in fields such as economics, philosophy, sociology, and engineering. There will be no parallel sessions. Each paper that is accepted is presented both (i) in a plenary session, meant for a short introduction and a sketch of the context and relevance; and (ii) in a poster session, where ample time is given for in-depth explanation and discussion. The poster-only track provides a second, free format presentation option. It is also open for preliminary results, challenges, etc. *New: non-proceedings papers* To adapt to different publication cultures in different fields, we introduce a new option: the non-proceeding papers. Authors may request that their contribution is not published in the proceedings in case this precludes later publication of an expanded journal version. The PC will decide on a case-by-case basis. If accepted, a one-page abstract will be published in the proceedings, and the paper must be freely available on-line (e.g., as a working paper). *Already Confirmed Invited Speakers* Massimo Marinacci, AXA-Bocconi Chair in Risk Department of Decision Sciences, Bocconi University, Milan, Italy Itzhak Gilboa, Professor of Economics and Decision Sciences Eitan Berglas School of Economics, Tel-Aviv University, Israel & HEC, Paris, France *Special Issue* After the conference, a special issue with a selection of the accepted papers will be published in an expanded version in the International Journal of Approximate Reasoning. *Steering Committee* T.

Martedì 4 novembre 2014 ore 13.00 *Scuola Normale Superiore* Pisa Aula Bianchi (Scienze) *Fabio Caccioli* *University College London* Terrà un seminario dal titolo: *“**Instabilities in portfolio optimization and regularization**”* *Abstract:* *We consider the problem of portfolio selection in presence of market impact, and we show that including a term which accounts for finite liquidity in portfolio optimization naturally mitigates the instabilities that arise in the estimation of coherent risk measures. This is because taking into account the impact of trading in the market is mathematically equivalent to introducing a regularization on the risk measure. We show that the impact function determines which regularizer is to be used, and we characterize the typical behavior of the optimal portfolio in the limit of large portfolio sizes for the case of Expected Shortfall*.

SUMMER SCHOOL ON COPULAS: Pau, France, July 13-17, 2015
by Gianfausto Salvadori 28 Oct '14

28 Oct '14

Dear Colleagues, all interested people (especially PhD and Post-doc students) are invited to attend the following Summer School on Copulas. *** SCOPE *** The statistical modeling of natural events frequently involves the modeling of the joint distribution of several random phenomena. Copulas are mathematical objects that are particularly suitable for modeling the multivariate dependence between several continuous random variables, independently of their marginal distributions. This explains why they are more and more often used in hydrology and environmental sciences. With the development of powerful statistical software (such as the R statistical system), a multivariate analysis based on copulas appears increasingly feasible. This one-week short course will focus on the theory and statistical practice of copulas with applications to hydrological problems and related environmental issues. It will also contain an introduction to multivariate extreme-value theory from a copula perspective. Theoretical concepts will be illustrated through the analysis of real-world datasets using the R statistical system. *** VENUE *** Université de Pau et des Pays de l'Adour. Pau, France, July 13-17, 2015 *** WEB SITE *** http://lma-umr5142.univ-pau.fr/copula/ PLEASE CIRCULATE THIS MAIL TO ALL INTERESTED PEOPLE.

METRON: Special Issue on "Latent Variable Models for the analysis of socio-economic data”
by Pierpaolo Brutti 27 Oct '14

27 Oct '14

================================================== METRON – Call for Papers for the Special Issue “Latent Variable Models for the analysis of socio-economic data” Guest Editors: Marco Alfó and Francesco Bartolucci ================================================== Latent variable (LV) models represent an important stream of the statistical literature with application in many fields, such as economics, medicine, psychology, and sociology, and are related to other important classes, such as that of finite mixture models. LV models are naturally applied whenever unobserved heterogeneity between sample units has to be taken into account, typically in a multilevel or longitudinal study, or the characteristic of interest (e.g. quality-of-life of patients suffering from a certain disease) is not directly observable. The special issue is intended to cover approaches based either on continuous or discrete latent variable models, with also particular interest in approaches that combine the use of continuous and discrete latent variables within the same model. The focus is on: - novel statistical approaches in terms of modelling formulations and/or estimation methods; - up-to-date case studies which address the application of such models to socio-economic data; - critical review papers with substantive insights on definition, estimation, and inference for the models of interest. We are enthusiastic of the opportunity offered by the special issue to disseminate LV models in the scientific community, not only among statisticians. Authors who are not sure whether their problems and ideas fall under the call for paper may preliminarily contact the Editors with an initial draft of the paper. All submitted papers under this call will undergo the standard review process of the journal. The deadline for the present call is November 30th, 2014. The special issue is handled through the website of the Journal; the editing and the review process will be handled by the Special Issue Editors Marco Alfó (Sapienza, University of Rome, email:marco.alfo@uniroma1.it) and Francesco Bartolucci (University of Perugia, IT, email: bart(a)stat.unipg.it). Please submit your manuscript at http://www.editorialmanager.com/tron/ ==================================================

Apologies for cross posting --------------------------------- SEMINARIO DI MATEMATICA APPLICATA Giovedi 23 Ottobre 2014, ore 11.30 Aula Rappresentanza, Dipartimento di Matematica (Via Saldini 50, Milano) Heterogeneities and the spatial spread of infectious diseases Dr. Vittoria Colizza INSERM & Universite Pierre et Marie Curie (Paris, France) ISI Foundation (Turin, Italy) ABSTRACT The spatial spread of infectious diseases depends on the interplay between local interactions among hosts (and possibly with vectors), along which transmission can occur, and dissemination opportunities presented by the movements of hosts (and vectors) among different communities or locations in space. Many degrees of heterogeneity may characterize this process, induced by large fluctuations in hosts' features (e.g. mixing behavior, frequency and duration of movements, topology and magnitude of movement fluxes) or by variations in pathogen's specific features (e.g. multiple circulation of different viruses, multiple types of transmission). To address these aspects, I'll present a general theoretical modeling framework taking into account the various heterogeneities at play and explore how these may affect the pandemic potential of an emerging infectious disease. Results are discussed in the realm of specific case studies.

Seminario KNAPIK

17 Oct '14

**************************************************************** STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO **************************************************************** Venerdi' 24 Ottobre 2014 alle ore 12:00, presso la sala rossa del Collegio Carlo Alberto, Moncalieri (TO), si terra' il seguente seminario: Bartek KNAPIK (Vrije Universiteit Amsterdam) CONVERGENCE RATES OF POSTERIOR DISTRIBUTIONS IN NONPARAMETRIC INVERSE PROBLEMS Abstract: Since the seminal works of Ghosal, Ghosh and van der Vaart (2000) and Shen and Wasserman (2001), posterior contraction has attracted much attention, resulting in the rich literature on this subject. However, these results are not suitable to deal with trully ill-posed inverse problems, where one is interested in the parameter of interest f, given noisy observations of its transformed version Kf. General theorems yield contraction results in some metric measuring the distance between Kf and Kf_0, whereas the interest lies in the distance betweend f and f_0, and these two metrics are not equivalent. In this talk we review (a part of) the existing literature on Bayesian approach to nonparametric inverse problems, and present a general contraction theorem. We show that in mildly ill-posed problems with conjugate priors, both empirical and hierarchical Bayes approaches lead to (nearly) optimal recovery of an infinite-dimensional parameter of interest. Moreover, using our general result, we obtain minimax adaptive concentration rates in two examples in the fixed-design regression setting. Tutti gli interessati sono invitati a partecipare. Il seminario e' organizzato dalla "de Castro" Statistics Initiative (http://www.carloalberto.org/stats) in collaborazione con il Collegio Carlo Alberto.

Seminario Kirone Mallick a Roma

17 Oct '14

The Asymmetric Simple Exclusion Process, a Review by Kirone Mallick (CEA, Saclay, Francia) Monday, 20 October 2014 from 16:00 to 18:00 (Europe/Rome) at Dip. di Fisica - Edificio G. Marconi ( Aula Conversi ) Abstract The asymmetric simple exclusion process plays the role of a paradigm to study various aspects of non-equilibrium statistical physics. It is a minimal model of interacting particles with transport, that displays interesting collective behaviour and breaks time-reversal symmetry. This system appears as a building block in more realistic descriptions of low-dimensional transport with constraints. During the last twenty years, a large number of exact results have been derived for the exclusion process. The aim of this talk is to review the main techniques used to study this system and some of the important results that have been obtained.

MOSTRA e CONFERENZA sul matematico René Gateaux
by Nappo, Giovanna 16 Oct '14

16 Oct '14

Vi segnalo la Mostra (21.24 ottobre) e la conferenza (21 ottobre) su René Gateaux presso il Dipartimento di Matematica Università di Roma "La Sapienza" MOSTRA René Gateaux (1889-1914) Itinerario di una gioventù perduta: Dipartimento di Matematica "Guido Castelnuovo" Università di Roma "La Sapienza" 21 -24 ottobre 2014 René Gateaux era un giovane matematico francese. Circa un milione e mezzo di francesi sono morti durante la Prima Guerra Mondiale, e René Gateaux è stato uno di loro. Qualche tempo prima della sua prematura scomparsa, avvenuta nella notte tra il 2 e il 3 ottobre 1914, ebbe diversi contatti scientifici con la comunità matematica romana e in particolare con Vito Volterra. In occasione del centenario dalla morte di René Gateaux, nei locali del Dipartimento di Matematica Guido Castelnuovo (piano terra), si terrà una mostra sui suoi contributi scientifici e sulla sua breve vita: il caso di René Gateaux apporta qualche interessante contributo alla conoscenza del suo periodo storico. La mostra si può visitare durante l'orario di apertura del Dipartimento di Matematica: dalle 8 alle 20. L'ingresso è gratuito Consulenti scientifici: Laurent Mazliak (Université Pierre et Marie Curie, Paris) e Rossana Tazzioli (Université de Lille 1) Concezione grafica: Raphaël Petit Organizzazione locale: Giovanna Nappo e Fabio Spizzichino (Dipartimento di Matematica) CONFERENZA Martedì 21 ottobre, ore 15:30, in Aula Picone del Dipartimento di Matematica "Guido Castelnuovo", il Professor Laurent Mazliak terrà una conferenza introduttiva. René Gateaux (1889-1914) abstract: Nell'ottobre 1914, il giovane matematico René Gateaux fu ucciso nei primi combattimenti della prima guerra mondiale. Aveva 25 anni. La sua fortuna postuma fu di essere stato, durante la sua breve vita, in relazione con importanti matematici, in particolare con Vito Volterra, e di avere lasciato prima di andare in guerra delle carte che diventarono, nelle mani esperte di Paul Lévy, la fonte di sviluppi capitali per la matematica del '900. Nella conferenza, considerata come un'introduzione e un complemento alla mostra omonima presso il Dipartimento di Matematica "Guido Castelnuovo", verranno presentati diversi aspetti di questo sorprendente destino. La conferenza sarà preceduta da una breve introduzione alla derivata di Gateaux, tenuta dal Prof. Antonio Siconolfi (Università di Roma "La Sapienza").

Fractional Calculus, Probability and Non-Local Operators: Second (and final) call for papers.
by Enrico Scalas 15 Oct '14

15 Oct '14

Second Call for papers Second Workshop on Fractional Calculus, Probability and Non-Local Operators: Applications and Recent Developments BCAM, Bilbao, Basque Country - Spain 10-14 November 2014 Research on non-local operators and related stochastic processes has witnessed a rapid expansion over the past years. These problems pose new challenges to both pure and applied mathematicians, at the interface of at least three wide fields: functional analysis, stochastic processes and partial differential equations, while providing a new paradigm in scientific modelling. Applications range from relativistic models of quantum physics and quantum field theory, to sub-diffusion experimentally observed in molecular physics, from anomalous transport in cells to leptokurtic price distributions in financial markets, or to long-range dynamics ranging from the nano-scale to the geophysical scale. This interaction between mathematics and applications is giving rise to new concepts and methods, and it will produce new challenging mathematical problems for many years to come. Programme Monday 10th - Wednesday 12th Mon 11:30-13:30 / 15:00-19:00 Tue 9:00-12:00 / 15:00-16:00 / 17:00-19:00 Wed 9:00-12:00 / 15:00–18:00 PhD/PostDoc level course on "Fractional Kinetics: Analytic and Probabilistic Approaches" Vassili Kolokoltsov (University of Warwick, UK) Jozsef Lorinczi (Loughborough University, UK) Enrico Scalas (University of Sussex, UK) Tue 16:00-17:00 BCAM Scientific Seminar J. M. Sanz-Serna (University “Carlos III” Madrid, Spain) “Nonsymplectic uses of symplectic integrators” Thursday 13th - Friday 14th Thu, Fri 9:30-12:00 / 15:00-17:30 Workshop with specialist talks presented by Invited Speakers and by young researchers. A permanent poster session will be organised as well.

Seminario Giuliana Cortese (Università di Padova) - 28/10/2014
by Giacomo Aletti 14 Oct '14

14 Oct '14

Con preghiera di diffusione tra tutti i possibili interessati, scusandomi per invii multipli. Cordialmente, Giacomo Aletti -------------- Si comunica che in data 28 Ottobre 2014, ore 11, presso la Sala di Rappresentanza del Dipartimento di Matematica dell'Università degli Studi di Milano La dott.ssa Giuliana Cortese, del dipartimento di Statistica dell'Università di Padova, terrà un seminario dal titolo "Dynamic predictions via competing risks regression models with application to chemotherapy in breast cancer" Abstract In breast cancer, the risk for cardiotoxicity due to chemotherapy typically increases with the cumulative dose of treatment over time. Therefore, it is of interest to predict the cumulative risk for cardiotoxicity in a dynamic way, while controlling the competing risk for mortality. For this purpose, we consider a competing risks regression model with two events, cardiotoxicity and death. A second aim is to predict optimal cumulative doses along a given treatment time that keep the cumulative risk for cardiotoxicity below a certain threshold (e.g. <5%). We face these prediction problems with different regression models for competing risks, accounting for all the time-dependent information in the data. For example, some covariates are assumed to have time-varying effects, and the cumulative dose was included as (internal) time-dependent covariate into the models. A landmark analysis was used to obtain dynamic predictions. In this applied context, we compare the competing risks approach based on cause-specific hazards and the direct regression models that allow finding a one-to-one relationship between cumulative risks and covariates. These models were then employed to predict optimal cumulative doses at a sequence of landmark time points. To control and correct also for the increased risk of dying, we finally predict optimal cumulative doses when a illness-death model is considered. Implementation in R is also discussed. -- ------------------------------- Giacomo Aletti, Associate Professor ADAMSS Centre (ex MIRIAM) Advanced Applied Mathematical and Statistical Sciences Department of Mathematics (www.matematica.unimi.it) Via Saldini, 50 20133 Milano, Italy Tel: +39-02-503.16158 Fax:+39-02-503.16090 Cell: +39-340-9739142

Seminario Sathyaa SUBRAMANIYAM (RGS & Matematica Applicata)
by Giacomo Aletti 13 Oct '14

13 Oct '14

Con preghiera di diffusione tra tutti i possibili interessati, scusandomi per invii multipli. Cordialmente, Giacomo Aletti -------------- Nell'ambito dei Reading Group Seminars e del Seminario di Matematica Applicata, il giorno lunedì 20 Ottobre 2014, alle ore 14.30, nell'Aula C del Dipartimento di Matematica dell'Universita' degli Studi di Milano, Via C. Saldini, 50, Milano, Sathyaa SUBRAMANIYAM - Department of Brain and Behavioral Science, University of Pavia, Italy - Consorzio Interuniversitario per le Scienze Fisiche della Materia (CNISM), Pavia, Italy terra' una conferenza dal titolo Detailed computation model for a cerebellar excitatory interneuron Abstract: Unipolar Brush Cells (UBCs) have been suggested to play a critical role in cerebellar functioning, yet the corresponding cellular mechanisms remain poorly understood. UBCs have recently been reported to generate, in addition to early-onset glutamate receptor-dependent synaptic responses, a late-onset response (LOR) composed of a slow depolarizing ramp followed by a spike burst (Locatelli et al., 2013). The LOR activates as a consequence of synaptic activity and involves an intracellular cascade modulating H- and TRP-current gating. In order to assess the LOR mechanisms, we have developed a UBC multi-compartmental model (including soma, dendrite, initial segment and axon) incorporating biologically realistic representations of ionic currents and a cytoplasmic coupling mechanism regulating TRP and H channel gating. The model finely reproduced UBC responses to current injection, including a burst triggered by a low-threshold spike sustained by CaLVA currents, a persistent discharge sustained by CaHVA currents, and a rebound burst following hyperpolarization sustained by H- and CaLVA-currents. Moreover, the model predicted that H- and TRP-current regulation was necessary and sufficient to generate the LOR and its dependence on the intensity and duration of mossy fiber activity. Therefore, the model showed that, using a basic set of ionic channels, UBCs generate a rich repertoire of bursts, which could effectively implement tunable delay-lines in the local microcircuit. ================= Reading Group Seminars: The Reading Group Seminars (RGS) are organized within an open community of researchers interested in applying up to date mathematical modeling and data analysis approaches to the study of biological systems.

Seminario di Probabilita'-Universita' di Padova

Ho il piacere di invitarvi al seguente seminario che si terrà Mercoledì 15 ottobre, alle ore 16.00, nell'aula 2BC30. del Dipartimento di Matematica dell'Università degli Studi di Padova. Speaker: Prof. Jan Swart Affiliation: Institute of Information Theory and Automation, Academy of Sciences of the Czech Republic Title: Particle systems with cooperative branching Abstract: In a cooperative branching system, pairs of particles, rather than individuals, produce offspring. Interacting particle systems with this sort of interaction have been used to model the effect of sexual reproduction and in particular the effect that in many species, a low population density reduces the reproductive success of individuals due to the difficulty of finding a partner. In this talk, I will review some older work on this sort of models and also discuss recent joint work with Anja Sturm on a model with cooperative branching and coalesence. For such a model in one dimension, we show that for low cooperative branching rates, the process dies out at the same geometric rate as a pure coalescent. The proof uses ideas related to a general duality for monotone systems due to Lawrence Gray. -- Alessandra Bianchi Dip. di Matematica Pura e Applicata Università di Padova Via Trieste, 63 - 35121 Padova, Italy phone: +39 049 827 14 06 fax: +39 049 827 14 28 e-mail: bianchi(a)math.unipd.it http://www.math.unipd.it/~bianchi/
