Analysis and Optimisation of Pulse Dynamics for Magnetic Stimulation
Magnetic stimulation, TMS, inductive stimulation, waveform optimization,neuron model, loss power.
2011/9/2
Magnetic stimulation is a standard tool in brain research and many elds of neurology, as well as psychiatry. From a physical perspective, one key aspect of this method is the ineciency of available ...
Abstract—We show a simple method for constructing an infinite family of graph formation games with link bias so that the resulting games admits, as a pairwise
stable solution, a graph with an arbitra...
Recurrent host mobility in spatial epidemics: beyond reaction-diffusion
beyond reaction-diffusion spatial epidemics
2011/9/2
Human mobility is a key factor in spatial disease dynamics and related phenomena. In computational models host mobility is typically modeled by diffusion in space or onmetapolulation networks. Alterna...
The interpretation of quantum mechanics and of probability: Identical role of the 'observer'
quantum mechanics probability
2011/9/14
The aim of the article is to argue that the interpretations of quantum mechanics and of probability are much closer than usually thought. Indeed, a detailed analysis of the concept of probability (wit...
Expository notes on Clifford algebras and spinors with a detailed discussion of Majorana, Weyl, and Dirac spinors. The paper is meant as a review of background material, needed, in particular, in now ...
Surrogate Parenthood: Protected and Informative Graphs
Surrogate Parenthood Protected Informative Graphs
2011/9/14
Many applications, including provenance and some analyses of social networks, require path-based queries over graphstructured data. When these graphs contain sensitive information, paths may be broken...
