--- AVVISO di SEMINARIO Dr. Gianni Pagnini BCAM & Ikerbasque, Bilbao, Spain Title: Fractional diffusion as an intermediate asymptotic regime. Abstract: A continuous-time random walk driven by two different Markovian hopping-trap mechanisms is investigated and it is shown that the paradigmatic features of anomalous diffusion are met. More precisely, anomalous diffusion results from a process that goes through the action of two co-existing Markovian mechanisms acting with different statistical frequency, and the probability of occurrence of this switch between the two Markovian settings originates and fully characterises the anomalous diffusion. In fact, ensemble and single-particle observables of this model have been studied and they match the main characteristics of anomalous diffusion as they are typically measured in living systems. In particular, the celebrated transition of the walker?s distribution from exponential to stretched-exponential and finally to Gaussian distribution is displayed by including also the Brownian yet non-Gaussian interval. Moreover, the model dynamically provides the power-law exponent of the mean-square displacement as a function of the probability of switching between the two Markovian states, namely the fractional order. Hence, fractional diffusion emerges as an intermediate asymptotic regime. Finally, within the present approach, fractional diffusion can be interpreted as a mathematical method for bridging two co-existing equilibrium states in a disordered medium.

Seminar Van Bever at UPO
by Enea Bongiorno 28 Oct '22

28 Oct '22

Dear colleagues, We are glad to invite you to the seminar that will take place on the 8th of November, at 16.00: - in presence: room 201 of the campus Perrone, via Perrone, 18, Novara Università del Piemonte Orientale, Dipartimento di Studi per l’Economia e l’Impresa. - on-line at the link: meet.google.com/yvq-ccbt-pzt Prof. Germain Van Bever Université de Namur, Belgio Title: Flexible Hilbertian Additive Regression with Small Errors-in-Variables Abstract: In this talk, we present a new framework of additive regression modelling for data in very generic settings. More precisely, we tackle the problem of estimating component functions of additive models where the regressors and/or response variable belong to general Hilbert spaces and can be imperfectly observed. By this,we mean that some variables can be either measured incompletely or with errors. Smooth backﬁtting methods are used to estimate consistently the component functions and we provide explicit rates of convergence. We amply illustrate our methodology in various settings, including the functional, Riemannian and Hilbertian settings.

Seminar Dombry @Bocconi - Thursday 3/11 at 12:00
by Giacomo Zanella 28 Oct '22

28 Oct '22

We are glad to announce the following seminar: Thursday, 3rd of November 2022 12:00, Room AS02 (only in presence, no online) Bocconi University, Via Roentgen 1, floor -1 Speaker: Clément Dombry (Université de Franche-Comté) Title: Stone's theorem and minimax rate of convergence for distributional regression Abstract: Distributional regression aims at estimating the full conditional distribution of the response variable given the covariates and is a fundamental tool in probabilistic forecast. In this talk, we prove Stone's theorem for distributional regression. It establishes universal consistency in Wasserstein distance of a large class of models based on local weights. Next we consider minimax rates of convergence on suitable classes of distributions and prove that nearest neighbor and kernel algorithms are rate optimal. Best regards, Giacomo Zanella

Thank you very much. Sincerely, Gianni Ps: further open positions at BCAM can be found at http://www.bcamath.org/en/research/job <http://www.bcamath.org/en/research/job> ============== Effective treatment strategies for rare diseases based on gene therapy Project summary Gene therapy medicinal products (GTMPs) are one of the most promising biopharmaceuticals, which are beginning to show encouraging results. Gene therapy based on the administration of DNA, messenger RNA (mRNA) or short-hairpin RNA (shRNA) are intended for gene augmentation or gene suppression, whereas the use of small interfering RNA (siRNA), microRNA, antisense oligonucleotides (ASOs) or aptamers provides posttranslational gene silencing. The efforts and advances made in this area have led to the development of new therapeutic strategies to treat several disorders, many of them without currently available treatments, as rare diseases. A key challenge for the clinical application of nucleic acid medicinal products entails the availability of delivery systems specifically adapted to their features and purpose. For a successful gene therapy, the delivery systems have to protect the genetic material from degradation, facilitating its internalization in target cells and releasing them intracellularly. The first step for an efficient internalization of the nucleic acid is the interaction between the delivery system and the cell membrane. Therefore, the understanding of the intracellular behaviour of the nanodelivery systems, the nucleic acid they carry (mRNA, DNA, siRNA, shRNA or ASO) and the endosomes after the internalization process will allow to advance in the design of nucleic acid based-nanomedicines aiming to improve the effectiveness of gene therapy treatments, by developing strategies for an improved intracellular delivery and endosomal escape. The issue of physical understanding and mathematical modelling of nanodelivering is still an open problem. As a matter of fact, anomalous diffusion emerged in living systems, namely, diffusing particles do not follow rules and properties of Brownian motion, and delivering by nanoparticles also goes according to anomalous diffusion such that modelling and understanding of anomalous diffusion is fundamental for gene therapy improvement. Therefore, new and advanced techniques are required for modelling such random motions and further studies needed for the understanding of the underlying statistical physics. It is well-known that anomalous diffusion is strongly related with fractional diffusion equations that are differential equations involving integral operators defined within the branch of mathematical analysis named Fractional Calculus. Under the point of view of statistical physics, these systems show not classical features as, for example, long-range correlations, power-law distributions, weak ergodicity breaking and aging. This framework calls for stochastic processes in inhomogeneous media and/or for heterogeneous ensembles of particles and then within the families, for example, of scaled Brownian motion and diffusing-diffusivity as well as those of the generalized gray Brownian motion and the superstatistical fractional Brownian motion, in general, and their under-damped extension. In general, the project aims to assess in deep the intracellular behavior of lipid nanoparticles for nucleic acid delivery for establishing models of anomalous diffusion useful to optimize the nanomedicines since the first steps of development. An important step towards further progress in the clinical application of gene therapy is expected and the results be applied in a number of delivery systems and diseases. The project will be mainly focused on the following rare diseases: Rare metabolic diseases; Rare retinal degenerative diseases; CAR therapy in pediatric acute leukemia, that are currently investigated by the PharmaNanoGene group at the Faculty of Pharmacy (UPV/EHU) and Bioaraba Health Research Institute. The development of the proper stochastic processes for nanodelivering and the interpretation of the corresponding statistical physics will be conducted by the Statistical Physics group at BCAM led by the proponent Ikerbasque Research Associate Gianni Pagnini has decades of experience in the field of fractional diffusion equations and the development of the related models, while the molecular simulations and advanced data analysis will be provided by the Mathematical, Computational and Experimental Neuroscience group at BCAM led by Ikerbasque Professor Serafim Rodrigues. — Gianni Pagnini Ikerbasque Research Associate BCAM - Basque Center for Applied Mathematics Alameda de Mazarredo, 14 E-48009 Bilbao, Basque Country - Spain Tel. +34 946 567 842 gpagnini(a)bcamath.org | www.bcamath.org/gpagnini ( matematika mugaz bestalde )

UNIBO Statistics Seminars: Davide Ferrari, Free University of Bolzano/Bozen
by Simone Giannerini 24 Oct '22

24 Oct '22

We are glad to announce the following Statistics Seminar: Friday, October 28, 11.30 a.m. Davide Ferrari (Free University of Bozen-Bolzano) Fast Construction of Optimal Composite Likelihoods Abstract A composite likelihood is a combination of low-dimensional likelihood objects useful in applications where the data have complex structure. Although composite likelihood construction is a crucial aspect influencing both computing and statistical properties of the resulting estimator, currently there does not seem to exist a universal rule to combine low-dimensional likelihood objects that is statistically justified and fast in execution. This paper develops a methodology to select and combine the most informative low-dimensional likelihoods from a large set of candidates while carrying out parameter estimation. The new procedure minimizes the distance between composite likelihood and full likelihood scores subject to a constraint representing the afforded computing cost. The selected composite likelihood is sparse in the sense that it contains a relatively small number of informative sub-likelihoods while the noisy terms are dropped. The resulting estimator is found to have asymptotic variance close to that of the minimum-variance estimator constructed using all the low-dimensional likelihoods.
