Combinatorics of tight geodesics and stable lengths [PDF]
, 2013 We give an algorithm to compute the stable lengths of pseudo-Anosovs on the curve graph, answering a question of Bowditch. We also give a procedure to compute all invariant tight geodesic axes of pseudo-Anosovs.

Behavior of Evaporation Ducts in Stable and Unstable Surface Layers
Radio Science, Volume 61, Issue 2, February 2026.Abstract The atmospheric surface layer over the ocean has a strong impact on electromagnetic (EM) wave propagation in the lowest 100 m of the atmosphere. Due to surface evaporation, a strong vertical gradient in water vapor forms in this layer, resulting in an evaporation duct which may greatly increase detection ranges for sensors and targets within ...

Integrating GPS with GLONASS for high‐rate seismogeodesy
Geophysical Research Letters, 2017 High‐rate GPS is a precious seismogeodetic tool to capture coseismic displacements unambiguously and usually improved by sidereal filtering to mitigate multipath effects dominating the periods of tens of seconds to minutes. We further introduced GLONASS (

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.Abstract Alaska's tectonic complexity makes it ideal for probing upper mantle deformation. We present a 3D shear‐wave anisotropy model obtained by inverting 7,985 SKS splitting intensity measurements from 261 broadband stations using 941 events from 2000 to 2023.
