Identifying interacting pairs of sites in Ising models on a countable set

Antonio Galves, Enza Orlandi and Daniel Yasumasa Takahashi

This paper addresses the problem of identifying pairs of interacting sites from a finite sample of independent realizations of the Ising model. We consider Ising models in a infinite countable set of sites under Dobrushin uniqueness condition. The observed sample contains only the values assigned by the Ising model to a finite set of sites. Our main result is an upper bound for the probability of misidentification of the pairs of interacting sites in this finite set.

A NeuroMat software, NES makes the headlines

The recent release of the initial version of Neuroscience Experiments System (NES), an open-source tool to manage clinical data gathered in hospitals and research institutions, has attracted wide media interest.

MEPHunter, a free software for signal visualization and analysis

NeuroMat, FAPESP's Research, Innovation and Dissemination Center for Neuromathematics, has become a reference for open-science tools, particularly free software, and has attracted potential partners.

Free software helps data management in Neuroscience experiments

Research, Innovation and Dissemination Center for Neuromathematics (NeuroMat) – one of the research centers supported by FAPESP – has launched the first module of the free software Neuroscience Experiments System (NES), that helps organization, control and management of neurophysiological data from patients and experiments.

Powers of Hamilton cycles in pseudorandom graphs

We study the appearance of powers of Hamilton cycles in pseudorandom graphs, using the following comparatively weak pseudorandomness notion. A graph G is (ε,p,k,ℓ)-pseudorandom if for all disjoint X and Y⊂V(G) with |X|≥ε(pˆk)n and |Y|≥ε(pˆℓ)n we have e(X,Y)=(1±ε)p|X||Y|.




The Research, Innovation and Dissemination Center for Neuromathematics is hosted by the University of São Paulo and funded by FAPESP (São Paulo Research Foundation).
