Nedo never sleeps and comes back in the new year with a sooper-special event: Manlio De Domenico (Universitat Rovira i Virgili, Tarragona, Spain) is going to present his seminar “Multilayer Network Maps of Functional Human Brain” (sorry for previous wrong titles). Here is the abstract:
Understanding how the human brain is structured, and how its architecture is related to the function, is of paramount importance for a variety of applications, including, but not limited to, new ways to prevent, deal with and cure brain diseases, such as Alzheimer’s or Parkinson’s, and psychiatric disorders, such as Schizophrenia. The recent advances in structural and functional neuroimaging, together with the increasing attitude to interdisciplinary approaches involving computer science, mathematics and physics, are fostering interesting results from computational neuroscience, that are quite often based on the analysis of complex network representation of human brain. In the last years, this representation experienced a theoretical and computational revolution that are breaching neuroscience, allowing to cope with the increasing complexity of human brain across multiple scales and in multiple dimensions, and to model structural and functional connectivity from new perspectives, often combined with each other.
In this talk we will discuss about one recently proposed approach, based on frequency decomposition, to represent the functional human brain as a multilayer network. We will briefly introduce the theoretical and computational tools required to analyze multilayer functional networks and we will show how this novel framework allows to distinguish between healthy and schizophrenic populations, achieving higher accuracy than conventional network approaches in clinical applications.
The seminar is going to be held in classroom 1 at 14 on the 31st of January, stay tuNEDO!
next Monday 19th of December at 16 in classroom 2, Michele Campisi (Scuola Normale Superiore, Pisa) is going to held the seminar “Fluctuation relations: exact results in nonequilibrium thermodynamics”.
Participate and stay tuNed(o)!
Imre Kondor will give a talk @IMT, entitled “On top and beyond networks“. Spatial and temporal coordinates of the event? December the 7th, classroom 1 of the San Francesco complex, at 16.00.

NETWORK VALUATION IN FINANCIAL SYSTEMS
PAOLO BARUCCA – UNIVERSITY OF ZURICH, LONDON INSTITUTE FOR MATHEMATICAL SCIENCES
With Marco Bardoscia, Fabio Caccioli, Marco D’Errico, Gabriele Visentin, Stefano Battiston, and Guido Caldarelli
Abstract: We introduce a network valuation model (hereafter NEVA) for the ex-ante valuation of claims among financial institutions connected in a network of liabilities. Similar to previous work, the new framework allows to endogenously determine the recovery rate on all claims upon the default of some institutions. In addition, it also allows to account for ex-ante uncertainty on the asset values, in particular the one arising when the valuation is carried out at some time before the maturity of the claims. The framework encompasses as special cases both the ex-post approaches of Eisenberg and Noe and its previous extensions, as well as the ex-ante approaches, in the sense that each of these models can be recovered exactly for special values of the parameters. We characterize the existence and uniqueness of the solutions of the valuation problem under general conditions on how the value of each claim depends on the equity of the counterparty. Further, we define an algorithm to carry out the network valuation and we provide sufficient conditions for convergence to the maximal solution.
Ok, guys, NEDO’s back in town for the 2nd season with a brand new website!
In order to begin the new season on the good foot, a special speaker is coming:
Paolo Barucca, LIMS, London on 12th October. Stay tuned!
Just to remember: the subject of the seminar is completely free of constraints, but the speaker have to use just blackboard and chalks.
Stay hungry, stay NEDO
