Transcranial electrical neuromodulation based on the reciprocity principle
Frontiers in Psychiatry, 2016 A key challenge in multi-electrode transcranial electrical stimulation (TES) or transcranial direct current stimulation (tDCS) is to find a current injection pattern that delivers the necessary current density at a target and minimizes it in the rest of ...

Focusing of geodesic congruences in an accelerated expanding Universe [PDF]
, 2012 We study the accelerated expansion of the Universe through its consequences on a congruence of geodesics. We make use of the Raychaudhuri equation which describes the evolution of the expansion rate for a congruence of timelike or null geodesics.

Blowups and blowdowns of geodesics in Carnot groups [PDF]
Journal of differential geometry, 2018 This paper provides some partial regularity results for geodesics (i.e., isometric images of intervals) in arbitrary sub-Riemannian and sub-Finsler manifolds.

Dense array EEG (dEEG) source estimation in neocortical epilepsy
Frontiers in Neurology, 2013 Rationale : Dense array EEG (dEEG) evenly covers the whole head surface with over 100 channels contributing to more accurate electrical source imaging due to the higher spatial and temporal resolution.

Geodesics of minimal length in the set of probability measures on graphs [PDF]
E S A I M: Control, Optimisation and Calculus of Variations, 2017 We endow the set of probability measures on a weighted graph with a Monge–Kantorovich metric induced by a function defined on the set of edges. The graph is assumed to have n vertices and so the boundary of the probability simplex is an affine (n − 2 ...

Liouville quantum gravity and the Brownian map II: Geodesics and continuity of the embedding [PDF]
Annals of Probability, 2016 We endow the √ 8/3-Liouville quantum gravity sphere with a metric space structure and show that the resulting metric measure space agrees in law with the Brownian map.

Evolutionary dynamics on a regular networked structured and unstructured multi‐population
International Journal of Robust and Nonlinear Control, EarlyView., 2023 Abstract In this paper, we study collective decision‐making in a multi‐population framework, where groups of individuals represent whole populations that interact by means of a regular network. Each group consists of a number of players and every player can choose between two options.

A note on geodesics in the Hayward metric [PDF]
, 2017 We study timelike and null geodesics in a non-singular black hole metric proposed by Hayward. The metric contains an additional length-scale parameter $\ell$ and approaches the Schwarzschild metric at large radii while approaches a constant at small ...

How can we determine if a spacetime is flat?
Frontiers in Physics, 2013 A spacetime is locally flat if and only if no geodesical deviation exists for congruences of all kinds of geodesics. However, while for causal geodesics the deviation can be measured observing the motion of (infinitesimal) falling bodies, it does not
