Effective counting of simple closed geodesics on hyperbolic surfaces [PDF]

open access: yesJournal of the European Mathematical Society (Print), 2019
We prove a quantitative estimate, with a power saving error term, for the number of simple closed geodesics of length at most $L$ on a closed hyperbolic surface of genus $g$.

Liouville quantum gravity and the Brownian map II: Geodesics and continuity of the embedding [PDF]

open access: yesAnnals 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.

Massively parallel computation of globally optimal shortest paths with curvature penalization

open access: yesConcurrency and Computation: Practice and Experience, Volume 35, Issue 2, 25 January 2023., 2023
Abstract We address the computation of paths globally minimizing an energy involving their curvature, with given endpoints and tangents at these endpoints, according to models known as the Reeds‐Shepp car (reversible and forward variants), the Euler‐Mumford elasticae, and the Dubins car. For that purpose, we numerically solve degenerate variants of the

Quasinormal modes of black holes with multiple photon spheres

open access: yesJournal of High Energy Physics, 2022
For a static and spherically symmetric black hole, a photon sphere is composed of circular null geodesics of fixed radius, and plays an important role in observing the black hole.

Blowups and blowdowns of geodesics in Carnot groups [PDF]

open access: yesJournal 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.

Slow-Frequency Pulsed Transcranial Electrical Stimulation for Modulation of Cortical Plasticity based on Reciprocity Targeting with Precision Electrical Head Modeling

open access: yesFrontiers in Human Neuroscience, 2016
In pain management as well as other clinical applications of neuromodulation, it is important to consider the timing parameters influencing activity-dependent plasticity, including pulsed versus sustained currents, as well as the spatial action of ...

The existence of null circular geodesics outside extremal spherically symmetric asymptotically flat hairy black holes

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
The existence of null circular geodesics in the background of non-extremal spherically symmetric asymptotically flat black holes has been proved in previous works.

Virtual reality hypnosis in the management of pain: Self‐reported and neurophysiological measures in healthy subjects

open access: yesEuropean Journal of Pain, Volume 27, Issue 1, Page 148-162, January 2023., 2023
Abstract Background Virtual reality hypnosis (VRH) has emerged as a new and promising option for pain management. Nonetheless, neural dynamics of pain modulation during VRH have not been investigated yet. The aim of this study was to measure the effects of VRH on pain, combining neurophysiological and self‐reported measurements.

Methods for Examining Electrophysiological Coherence in Epileptic Networks

open access: yesFrontiers in Neurology, 2013
Epilepsy may reflect a focal abnormality of cerebral tissue, but the generation of seizures typically involves propagation of abnormal activity through cerebral networks.
