Harnessing functional segregation across brain rhythms as a means to detect EEG oscillatory multiplexing during music listening
2018
Journal of Neural Engineering
Our methodology includes an efficient graph-partitioning algorithm, which is further utilized for mining prototypical modular patterns, and a novel algorithmic procedure for identifying switching nodes ...
Our results suggest the multiplex character of the music-induced functional reorganization and particularly indicate the dependence between the networks reconstructed from the δ and βH rhythms. ...

Identifying supersingular elliptic curves
2012
LMS Journal of Computation and Mathematics
We analyze the complexity of several existing algorithms and then present a new approach that exploits structural differences between ordinary and supersingular isogeny graphs. ...
Both these complexity bounds are significant improvements over existing methods, as we demonstrate with some practical computations. ...
I am grateful to David Kohel for his feedback on an early draft of this paper, and for showing how to tighten the bound in Proposition 1. ...

Phase synchrony analysis of EEG during music perception reveals changes in functional connectivity due to musical expertise
2005
Signal Processing
Comparing the music listening task to rest or control condition, musicians showed increase in phase synchrony over distributed cortical areas, both near and distant, in delta, and most conspicuously in ...
Differences in functional and topographical connectivity patterns between two groups, musicians and non-musicians, during attentively listening to three different pieces of music and to a text of neutral ...

Detecting projectivity in sheaves associated to representations of infinitesimal groups
2015
Journal of Pure and Applied Algebra
We consider sheaves over the projectivization P(G) of V(G) constructed from a G-module M. We show that if P(G) is regular then the sheaf H^[1](M) is zero if and only if M is projective. ...
Along the way we will provide new proofs of some known results and correct some errors in the literature. ...
