Whole-brain structural connectivity in temporal lobe epilepsy: a Diffusion Spectrum Imaging study

Jean-Philippe Thiran, Alessandra Griffa, Alessandro Daducci, Alia Lemkaddem, François Lazeyras

Introduction: Medial Temporal Lobe Epilepsy (mTLE) with hippocampal sclerosis is the most frequent cause of drug-resistant focal epilepsy in adults. These patients suffer from widespread subtle white matter abnormalities and abnormal functional connectivit ...

A Game Theoretic Approach to Expander-based Compressive Sensing

Volkan Cevher, Sina Jafarpour

We consider the following expander-based compressive sensing (e-CS) problem: Given Φ ∈ ℝM×N (M

A lower bound for algebraic connectivity based on the connection-graph-stability method

Martin Hasler, Ali Ajdari Rad, Mahdi Jalili

This paper introduces the connection-graph-stability method and uses it to establish a new lower bound on the algebraic connectivity of graphs (the second smallest eigenvalue of the Laplacian matrix of the graph) that is sharper than the previously publish ...

Wavelets on graphs via spectral graph theory

Pierre Vandergheynst, Rémi Gribonval

We propose a novel method for constructing wavelet transforms of functions defined on the vertices of an arbitrary finite weighted graph. Our approach is based on defining scaling using the the graph analogue of the Fourier domain, namely the spectral deco ...

An Improved LP-based Approximation for Steiner Tree

Thomas Rothvoss, Laura Sanità

The Steiner tree problem is one of the most fundamental

\mathbf{NP}

-hard problems: given a weighted undirected graph and a subset of terminal nodes, find a minimum-cost tree spanning the terminals. In a sequence of papers, the approximation ratio for thi ...

Multicomponent wavefield characterization with a novel scanning laser interferometer

Thomas Emmanuel Blum

The in-plane component of the wavefield provides valuable information about media properties from seismology to nondestructive testing. A new compact scanning laser ultrasonic interferometer collects light scattered away from the angle of incidence to prov ...

When will the zebra mussel reach Florence? A model for the spread of Dreissena polymorpha in the Arno water system (Italy)

Lorenzo Mari, Marino Gatto

The zebra mussel (Dreissena polymorpha) is a freshwater bivalve that has caused dramatic ecological and economic impacts worldwide in the last decades. Its success as ecosystem invader is mainly due to the species ability of spreading along rivers, togethe ...

Early consensus in complex networks under variable graph topology

Martin Hasler, Leonidas Georgopoulos

Analysis of the linear algorithm for consensus on complex networks shows the existence of two distinct phases, the asymptotic and the transient. The network reaches the asymptotic when the components corresponding to the spectral gap eigenvalue of the weig ...

Synchronizability of dynamical networks: different measures and coincidence

Ali Ajdari Rad, Mahdi Jalili

In this paper, we list four different interpretations of synchronizability, study their profile in different network structures and give evidence that they do not coincide, in general. By changing the network topological properties, their behavior is track ...
