A boat with a furled sail at rest in a harbor. In truth it pictures not my destination But my life. For love was offered me and I shrank from its disillusionment; Sorrow knocked at my door, but I was afraid; Ambition called to me, but I dreaded the chances. Yet all the while I hungered for meaning in my life. And now I know that we must lift the sail And catch the winds of destiny Wherever they drive the boat. To put meaning in one?s life may end in madness, But life without meaning is the torture Of restlessness and vague desire ? It is a boat longing for the sea and yet afraid."

Call for abstracts: "Statistical mechanics approaches to earth system dynamics'' EGU Session
by Giulia Carigi 13 Dec '21

13 Dec '21

Dear Colleagues, with apologies for cross-posting, we would like to draw your attention to the session NP1.1 ``Statistical mechanics approaches to earth system dynamics: invariant measures, response, and large deviations'' to be held as part of the upcoming General Assembly of the European Geosciences Union (Vienna, Austria, 3rd to 8th of April 2022). A short description of the session can be found here https://meetingorganizer.copernicus.org/EGU22/session/42646 or at the end of this email. We would be very happy if you could consider submitting an abstract to this session. IMPORTANT: deadline for abstract submission is 12 January 2022, 13:00 CET For further info on abstract submission see here: https://egu22.eu/abstracts_and_programme/how_to_submit_an_abstract.html EGU2022 will be a hybrid conference – more information at https://egu22.eu/about/provisional_meeting_format.html Best wishes, Jochen Broecker (Convener), Vera Melinda Galfi, Giulia Carigi, Georgios Margazoglou, Jeroen Wouters (Co-Conveners) SESSION DESCRIPTION: The equations governing the dynamics of the atmosphere and the ocean provide us with an enormously powerful tool to understand and predict the future evolution of these dynamics. By integrating these equations forward in time from a given initial condition, we are able to produce highly realistic trajectories of the earth system's temporal evolution. A number of scientific questions however consider the statistical behaviour of solution ensembles, with the heterogeneity coming from different (yet ``typical'') initial conditions or random external forces. Examples are questions related to the global mean temperature or rainfall, the frequency of extreme events, but also questions regarding the average predictability of the system or its susceptibility to external perturbations. Statistical mechanics provides a framework in which such questions can be addressed. Rather than considering individual solutions, randomness and uncertainty are introduced to describe the ensemble of solutions in a probabilistic manner. This statistical mechanics approach to earth system dynamics will be the theme of this session. Contributions will cover a broad range of aspects from theory to applications and from mathematics to climate science. Topics include: * Novel mathematical techniques from the theory of stochastic processes and PDE's * Examples of ideas and methods from statistical mechanics being applied to the earth system (including, but not limited to, linear response, model reduction, large deviations and related algorithms) * Potential future applications, for instance in downscaling, data assimilation and parametrisations ----------------------------------------------------------------- Giulia Carigi, Postdoctoral Research Fellow Department of Mathematics and Statistics University of Reading, UK

Seminar by A. Picarelli in Padova (this Friday)!
by Giorgia Callegaro 13 Dec '21

13 Dec '21

Dear all, it is a pleasure to announce the forthcoming seminar by *Athena Picarelli* (Università di Verona), which will be held *in person* room 2BC30 of the Mathematics Department (Torre Archimede) of the University of Padova and online, via Zoom, this Friday. Here are the details: * Date and time: 17 December, 14.30 pm * Title: *Optimal management of pumped hydroelectric production with state constrained optimal control* * Abstract: We present a novel technique to solve the problem of managing optimally a pumped hydroelectric storage system. This technique relies on representing the system as a stochastic optimal control problem with state constraints, these latter corresponding to the finite volume of the reservoirs. Following the recent level-set approach presented in O. Bokanowski, A. Picarelli, H. Zidani, State-constrained stochastic optimal control problems via reachability approach, SIAM J. Control and Optim. 54 (5) (2016), we transform the original constrained problem in an auxiliary unconstrained one in augmented state and control spaces, obtained by introducing an exact penalization of the original state constraints. The latter problem is fully treatable by classical dynamic programming arguments. * Zoom link: please visit the webpage https://www.math.unipd.it/~bianchi/seminari/ Thanks for your attention and see you soon in Padova, Giorgia Callegaro -- Giorgia Callegaro Associate Professor Department of Mathematics - University of Padova Via Trieste 63 , I-35121 Padova - ITALY Tel: +39-0498271481 Fax: +39-0498271499 E-Mail: gcallega(a)math.unipd.it <https://webmail.math.unipd.it/horde3/imp/message.php?mailbox=Sent&index=598#> Personal web-page: https://sites.google.com/site/giogiocallegaro/Home

Seminar in Statistics LORENZO MASOERO
by Pierpaolo De Blasi 10 Dec '21

10 Dec '21

SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.carloalberto.org/events/category/seminars/seminars-in-statistic…> Venerdi 17 Dicembre 2021, alle ore 12.00, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Speaker: *Lorenzo Masoero *(Amazon) Title: *Improved prediction and optimal sequencing strategies for genomic variant discovery via Bayesian nonparametrics* Abstract:Despite the advent of Big Data, data-gathering in many domains can still be an expensive process that necessitates careful planning when operating under a fixed, limited budget. For instance, sequencing new genomic data is a complex procedure that requires careful tuning: researchers can spend resources to sequence a greater number of genomes (quantity), or spend resources to sequence genomes with increased accuracy (quality). In this talk, I consider the common setting in which scientists have already conducted a pilot study to reveal variants in a genome and are contemplating a follow-up study. Spending additional resources has the potential to reveal new variations in the genome, and thereby new genetic insights. Therefore, practitioners are interested in (i) predicting how many new discoveries they will make under different experimental design choices. In turn, they can leverage these predictions to optimally allocate available resources in the design of a future experiment, e.g. (ii) to maximize the number of future discoveries or (iii) to optimize the usefulness of a future experiment for the task at hand, e.g. the power of an associated statistical test. I discuss novel methodologies to solve the problems mentioned above. Our approach relies on a Bayesian nonparametric formulation that facilitates (i) prediction for the number of new variants in the follow-up study based on the pilot study. We show empirically that, when experimental conditions are kept constant between the pilot and follow-up, our method's prediction is competitive with the best existing methods. Unlike current methods, though, our new method allows practitioners to change experimental conditions between the pilot and the follow-up. We demonstrate how this distinction allows our method to be used for more realistic predictions and for optimal allocation of a fixed budget between quality and quantity. In particular, we first show how, under a fixed budget, my predictions can be used to maximize (ii) the number of new genomic variants discovered in a follow-up study. Last, we show how our framework can guide practitioners in other experimental design problems, and specifically how to achieve (iii) the highest possible power in statistical tests in the context of rare variants association studies. ------------------------------------------------ In ottemperanza alle norme anti Covid, per partecipare in presenza è necessario prenotarsi tramite il seguente form online: https://forms.gle/jVPLoDCQ1ANSB5dg8 Sarà possibile seguire il seminario anche in streaming: Join Zoom Meeting <https://us02web.zoom.us/j/88971670320?pwd=VXFseHNlYm5EKzFmZ25oTGdlRWw4QT09> Meeting ID: 889 7167 0320 Passcode: 362208 Il seminario è organizzato dalla "de Castro" Statistics Initiative www.carloalberto.org/stats Cordiali saluti, Pierpaolo De Blasi --- University of Torino & Collegio Carlo Alberto carloalberto.org/pdeblasi <https://sites.google.com/a/carloalberto.org/pdeblasi/>

(PMS)^2 online talk: Martin Huesmann (Dec 13, 5:30pm)
by Mario Maurelli 08 Dec '21

08 Dec '21

Dear colleagues, We are happy to announce the following online talk: Speaker: *Martin Huesmann* (Universität Münster) *Title*: A fluctuation result for the optimal matching problem *Abstract*: The optimal matching problem is one of the classical random optimization problems. While the asymptotic behavior of the expected cost is well understood only little is known for the asymptotic behavior of the optimal couplings - the solutions to the optimal matching problem. In this talk we show that at all mesoscopic scales the displacement under the optimal coupling converges in suitable Sobolev spaces to a Gaussian field which can be identified as the curl-free part of a vector Gaussian free field. Based on joint work with Michael Goldman. Date and time: *Monday December 13, 17:30-18:30* (Rome time zone) *Zoom link*: https://us02web.zoom.us/j/8342220461 This is a talk of the *(PMS)^2: Pavia-Milano Seminar series on Probability and Mathematical Statistics* organized jointly by the universities Milano-Bicocca, Pavia, Milano-Politecnico and Milano-Statale. For more information see the dedicated webpage: https://paviamilanoseminars.wordpress.com/ Participation is free and welcome! Best regards The organizers (Mario Maurelli, Carlo Orrieri, Maurizia Rossi, Margherita Zanella)

Reminder -- Online Quantitative Finance Seminars @SNS, December 10, 2021
by Giulia Livieri 07 Dec '21

07 Dec '21

Dear all, We would like to announce the following two Online Seminars @SNS: *December 10, 2021 at 3PM (CEST)* *Speaker: *Prof. Agostino Capponi (Columbia University) *Title: * The Adoption of Blockchain-based Decentralized Exchanges (joint work with Dr. Ruizhe Jia) *Abstract: *We show that the blockchain order execution mechanism and liquidity pooling create arbitrage rents in decentralized exchanges. The arbitrage rent raises the cost of liquidity provision and imposes negative externalities on users of the underlying blockchain. In equilibrium, automated market makers (AMMs) are adopted by liquidity providers only if exchange rates of token pairs are sufficiently stable. A pricing curve with higher curvature reduces arbitrage rents, but also decreases trading activities. We provide statistical support for our main model implications using transaction-level data of AMMs. *Link: * https://teams.microsoft.com/l/meetup-join/19%3ameeting_NjAyODk0YzQtNmVmYS00… We are looking forward to seeing you at the seminars! Best regards, Giulia
