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, in collaborazione col centro ADAMSS e il CIMAB, il giorno lunedì 25 Maggio 2015, alle ore 14.30, nell'Aula C del Dipartimento di Matematica dell'Universita' degli Studi di Milano, Via C. Saldini, 50, Milano, "Information coding in vestibular hair cells" Paola PERIN University of Pavia Abstract: Hair cells are the mechanoreceptors in our auditory and vestibular systems. Vestibular afferent neurons are classified on the basis of their motion selectivity (direction, response to linear vs. angular motion), discharge regularity, gain and dynamics (tonic vs. phasic). The properties of vestibular hair cells and afferent fibers are optimized for the transduction for low frequency stimuli (head motion, mostly below 50 Hz). Moreover, vestibular hair cells display a resting transmitter release rate which is used to set a baseline: increases above resting discharge signal movements in one direction, decreases signal movements in the opposite direction. Whereas discharge regularity appears to be a postsynaptic property, afferent dynamics is determined presynaptically, but the mechanisms involved are still unclear. In our work we have recorded currents, voltages and release from vestibular hair cells from the frog utricle and built a model of a hair cell connected to an afferent fiber upon mechanical stimulation. Our results suggest that dynamics is affected by ion currents (especially BK and IA) whereas presynaptic release properties affect resting discharge but not postsynaptic dynamics. ================ Per chi volesse seguire il seminario in remoto ricordo inoltre che sarà possibile dopo aver segnalato il proprio interessamento entro le 12 del giorno del seminario. ================= 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. The RGS take place at the Math. Department in Milan (via Saldini). Initiatives and updates are published on the website: http:// rgs.mat.unimi.it/.

**************************************************************** STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO **************************************************************** Venerdi 22 Maggio 2015 alle ore 12:00, presso l’Aula Rossa del Collegio Carlo Alberto, Moncalieri (TO), si terra' il seguente seminario: Luca TARDELLA (Università di Roma "La Sapienza”) FLEXIBLE BEHAVIORAL CAPTURE-RECAPTURE MODELLING Abstract: We develop some new strategies for building and fitting new flexible classes of para- metric capture-recapture models for closed populations which can be used to address a better understanding of behavioural patterns. We first rely on previous approaches based on a conditional probability parameterization and review how to regard a large subset of standard capture-recapture models as a suitable partitioning in equivalence classes of the full set of conditional probability parameters. We then propose a regression approach combined with the use of new suitable quan- tifications of the conditioning binary partial capture histories as a device for enlarging the scope of flexible behavioural models and also exploring the range of all possible partitions. We show how one can easily find unconditional MLE of such models within a generalized linear model framework. We illustrate the potential of our approach with the analysis of some known datasets and a simulation study. 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.

de Finetti Risk Seminar - May 2015
by Emanuela Rosazza 14 May '15

14 May '15

On behalf of the Scientific Committee of the de Finetti Risk Seminars, we are glad to invite you to participate at the following Lecture Financial Models with Defaultable Numeraires Johannes Ruf University College London ABSTRACT Financial models are studied where each asset may potentially lose value relative to any other. To this end, the paradigm of a pre-determined nume raire is abandoned in favour of a symmet- rical point of view where all assets have equal priority. This approach yields novel versions of the Fundamental Theorems of Asset Pricing, which clarify and extend non-classical pricing formulas used in the financial community. Furthermore, conditioning on non-devaluation, each asset can serve as nume raire and a classical no-arbitrage condition be formulated. It is shown when and how these local conditions can be aggregated to a global no-arbitrage condition. Joint work with Travis Fisher and Sergio Pulido LOCATION: The seminar will be held on Wednesday, May 20, at 18.00, Aula di Rappresentanza, Dipartimento di Matematica, Università di Milano, Via 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 Probabilita' - Universita' di Padova
by alessandra bianchi 12 May '15

12 May '15

Ho il piacere di invitarvi al seguente seminario, che si terrà lunedì 18 maggio alle ore 14:30 nell'aula 2BC30 del Dipartimento di Matematica dell'Universita' degli Studi di Padova. SPEAKER: Stefan Grosskinsky (Mathematics Institute, University of Warwick) TITLE: Metastability in condensing zero-range processes ABSTRACT: We consider a zero-range process with jump rates decreasing with the occupation number, which is known to exhibit a condensation phenomenon where a finite fraction of all particles concentrates on a single lattice site. We derive a scaling limit for the asymptotic stationary dynamics of the condensate location in the thermodynamic limit on a one-dimensional torus. Our proof follows previously developed methods using potential theory and a martingale approach, which have been applied to zero-range processes on finite lattices. The main challenge and novelty of our paper arises from the absence of attractor states which complicates the proof of equilibration within metastable wells and requires a coupling argument to get uniform bounds on exit rates from wells. This is joint work with Ines Armendariz and Michalis Loulakis. -- Alessandra Bianchi Dip. di Matematica 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/

Seminario Dott.Torrisi (presso Dip. Scienze Statistiche, Roma)
by Alessandro Degregorio 11 May '15

11 May '15

----------------------------------------------------------------------------- A v v i s o d i S e m i n a r i o ----------------------------------------------------------------------------- Venerdì 15 Maggio, ore 10,30 ----------------------------------------------------------------------------- Stanza 34 Dipartimento di Scienze Statistiche Sapienza Università di Roma Dott. Giovanni Luca Torrisi (CNR-Istituto per le Applicazioni del Calcolo) Title Probability approximation of spatial point processes Abstract: We give a quantitative Gaussian and Poisson approximation for the first chaos (or innovation) of spatial point processes with conditional intensity. To this aim we use a Malliavin-Stein-Chen approach. This method is essentially based on the following two steps. First, we provide an integration by parts (IBP) formula which relates the first chaos with the discrete Malliavin operator. Second, we derive the probability approximations by combining the IBP formula with the Stein and Chen methods. Our findings extend the corresponding results on the Poisson space due to Peccati, Solè, Taqqu and Utzet (2010) and Peccati (2011). The general bounds presented in this talk are applied to stationary, inhibitory and finite range Gibbs point processes with pair potential, providing explicit error bounds and quantitative limit theorems. Tutti gli interessati sono invitati a partecipare. Saluti Alessandro De Gregorio
