Long‐Wavelength Ionospheric Compensation of InSAR Time‐Series Based on Global Ionosphere Maps

open access: yesGeophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract Uncorrected long‐wavelength contributions remain a major limitation for interpreting InSAR time‐series over large areas (>100 km). Among them, the ionosphere can impact InSAR measurements across various timescales, potentially biasing secular velocity estimates.

QCD topological susceptibility from the nonlocal chiral quark model

open access: yes, 2016
We investigate the QCD topological susceptibility $\chi_t$ by using the nonlocal chiral quark model (NL$\chi$QM). This model is based on the liquid instanton QCD-vacuum configuration in which $\mathrm{SU}(3)$ flavor symmetry is explicitly broken by the ...

A Multi‐Component Writing Intervention With and Without Peer‐Tutoring on Text Production of Diverse Struggling L1 and L2 Writers

open access: yesPsychology in the Schools, Volume 62, Issue 12, Page 4917-4934, December 2025.
ABSTRACT Writing proficiency is a global educational challenge, particularly in diverse student populations. This study examined the effectiveness of a multi‐component intervention based on the Self‐Regulated Strategy Development (SRSD) framework, incorporating graphic organizers, storytelling, and positive reinforcement.

Strain Rates Along the Alpine‐Himalayan Belt From a Comprehensive GNSS Velocity Field

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract The Alpine‐Himalayan belt is one of Earth's most dynamic and complex regions, characterized by intense tectonic deformation and seismicity. Comprehensive analyses of continental‐scale crustal deformation and seismic hazards along this extensive orogenic belt require the compilation of large geodetic data sets.

Dependence of IGS Products on the ITRF Datum [PDF]

open access: yes, 2012
Throughout its nearly two decades, the International GNSS (Global Navigation Satellite Systems) Service (IGS) has sought to align its products closely to successive realizations of the International Terrestrial Reference Frame (ITRF). This has been disruptive for IGS users at times, especially during the 1990s when some radical ITRF datum choices were ...
