Efficient traveltime solutions of the acoustic TI eikonal equation
, 2013 Numerical solutions of the eikonal (Hamilton-Jacobi) equation for transversely isotropic (TI) media are essential for imaging and traveltime tomography applications.

Automated Centerline Extraction From Meshed Vascular Models
International Journal for Numerical Methods in Biomedical Engineering, Volume 42, Issue 6, June 2026.A method to extract centerlines from image‐based vascular meshes is presented, which automatically identifies vascular endpoints and traces centerlines by solving Eikonal equations. Compared to a widely used method, the proposed approach requires less user interaction and demonstrates better robustness on models that contain segmentation artifacts from

Seismic imaging of the critical zone of dolerite dykes at Cap Fréhel in Brittany (France)
Near Surface Geophysics, Volume 24, Issue 3, Page 262-288, June 2026.Abstract In June 2023, we measured ten near‐surface seismic profiles to image the critical zone of dolerite (diabase) dykes that cut the sandstone at Cap Fréhel in Brittany (France). Seismic ray tracing and inversion are used to determine the thickness of the regolith layer from first‐arrival P‐wave traveltimes.

Ringdown Modulation of Acceleration Radiation in the Schwarzschild Background
Fortschritte der Physik, Volume 74, Issue 6, June 2026.ABSTRACT We derive an analytic first‐order description of how Schwarzschild ringdown affects a detector‐based detailed‐balance diagnostic in a near‐horizon, single‐mode setting. A freely falling two‐level system couples to a cavity‐filtered outgoing mode of fixed asymptotic frequency, whose static Schwarzschild response gives geometric photon ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.Abstract In situ CO2 mineral storage is gaining increasing attention as a carbon capture and storage (CCS) technology to reduce anthropogenic CO2 emissions. So far, in situ CO2 mineral storage projects have been monitored predominantly using fluid‐ and isotope geochemical methods.

KNOTS, BRAIDS AND HEDGEHOGS FROM THE EIKONAL EQUATION [PDF]
Modern Physics Letters A, 2005 The complex eikonal equation in the three space dimensions is considered. We show that apart from the recently found torus knots, this equation can also generate other topological configurations with a nontrivial value of the π2(S2) index: braided open strings as well as hedgehogs. In particular, cylindric strings, i.e.

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.Abstract Deformation along oceanic transform faults is partitioned between seismic and aseismic slip, controlled by lithology, thermal structure, and fluid circulation. We analyze one year of data from a 54‐station ocean bottom seismometer network deployed across the Blanco Transform Fault (BTF), Northeast Pacific.
