Spatial Dependence of High‐Frequency Ground Motion Along the Chilean Subduction Zone From Aftershock Sequences of the Mw 8.8 Maule and Mw 8.2 Iquique Earthquakes

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract The Chilean subduction zone is a highly active seismic region, producing megathrust earthquakes approximately every decade. We apply a stochastic approach to assess spatial variations in seismic wave characteristics along the Chilean trench using weak motion data.

An Investigation of Pump-Induced Conditioning in NCWI of Concrete

e-Journal of Nondestructive Testing
Coda Wave Interferometry (CWI) is a highly sensitive ultrasonic method for damage detection, but it often fails to see elastic nonlinearities such as closed cracks.

A Physics‐Based Frequency‐Temperature Seismic Anelastic Attenuation Model for Planetary Ice Shells

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Intrinsic attenuation in planetary ices remains poorly constrained at seismic frequencies and low temperatures, limiting quantitative predictions of wave propagation in icy moons. Existing models typically rely on constant‐Q, or power‐law formulations that lack microphysical grounding and fail to capture the strong temperature sensitivity of ...

Low Frequency Extensions of Cyclotron Maser Instability‐Generated Radio Emission: A Statistical View From Cassini at Saturn

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract The Cassini spacecraft spent 13 years orbiting Saturn, quasi‐continuously measuring Saturn's radio emissions. One of the key elements of the radio spectrum at Saturn is the Saturn Kilometric Radiation (SKR), and several studies have been written on events called Low Frequency Extensions (LFEs) which represent strong, continuous extensions of ...

Temporal Changes in the Earth's Outer Core From Nuclear‐Test PKP Waves

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract We investigate temporal changes in P‐wave velocity in the outer core using short‐period PKP waves generated by underground nuclear tests conducted in French Polynesia and recorded at seismic station BRVK in Kazakhstan. The observed first arriving PKP phase cannot be explained by ray theory.

The Red‐Blue Heuristics: How Citizens Manage Institutionalized Coalition Politics

Scandinavian Political Studies, Volume 49, Issue 3, August 2026.
ABSTRACT Coalition politics represents a challenge to democratic citizens: they need to consider which governing coalitions a party is willing to enter or support in order to make informed vote choices. Following a minimalist perspective, several scholars have suggested that citizens rely on universal heuristics, such as left‐right placement, when ...

Characteristics of Coda Waves and Inhomogeneity of the Earth.

Journal of Physics of the Earth, 1995
During the last twenty years, the characteristics of seismic waves scattered by inhomogeneous structure in the earth have been gradually clarified by many studies. The composition of P- and S-coda waves has been investigated using seismograms observed by seismic arrays.

Textured Piezoelectric Ceramics Printed With Baffled Nozzles

Journal of the American Ceramic Society, Volume 109, Issue 8, August 2026.
To better align platelet particles in additively manufactured textured ceramics, baffled nozzles were simulated and tested. The simulation included a novel CFD heuristic that considers the entire print path. Printed parts were characterized via microscopy, X‐ray diffraction, and electromechanically and results were compared to the simulation, finding ...

The passion of butterflies: Notes on “translating” a Navajo poem by Rex Lee Jim

Journal of Linguistic Anthropology, Volume 36, Issue 2, August 2026.
Abstract This essay honors three kinds of tradition. The first tradition is the poetry of Rex Lee Jim. The second tradition is the translation work of Blackhorse Mitchell. The third tradition is the discourse‐centered and ethnopoetic tradition of linguistic anthropology. I do this by focusing on a brief poem in Navajo by Rex Lee Jim.
