Properties of the Complete Phonon Spectrum of Anisotropic One- and Three-layer Wurtzite Nanostructures [PDF]
Журнал нано- та електронної фізики, 2017 Within the Loudon dielectric continuum model, the theory of phonon spectrum is developed for the anisotropic wurtzite nanostructures: plane one-layer with binary and ternary components and three-layer with the same components.

Journal of Agrarian Change, Volume 26, Issue 2, April 2026.ABSTRACT This paper advances scholarship on agri‐alternatives by probing the gap between romanticised narratives of how alternative farming transitions ought to be and the actual practices farmers enact in their fields. Focusing on moments when such alternatives encounter on‐the‐ground realities, we propose ambiguous ecologies as a lens to explore the ...

Mutual Detectability: A Targeted SETI Strategy That Avoids the SETI Paradox
The Astronomical Journal, 2020 Abstract As our ability to undertake searches for extraterrestrial intelligence (SETI) grows, so does interest in the controversial endeavor of messaging extraterrestrial intelligence (METI). METI proponents point to the SETI Paradox—if all civilizations refrain from METI then SETI is futile.

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.Abstract The JPL rover Perseverance's investigations of Jezero crater's floor reveal that the ultramafic Séítah formation and the overlying mafic Máaz formation are deformed into a broad, low‐amplitude structural dome. Mastcam‐Z stereo images processed into digital outcrop models, together with RIMFAX ground‐penetrating radar profiles, were used to ...

Al‐Khadhaf: The first camera‐observed (H5–6) meteorite fall from Oman
Meteoritics &Planetary Science, Volume 61, Issue 3, Page 522-547, March 2026.Abstract A fireball camera system installed in 2022 by the Oman Meteorite Monitoring Project (OMMP) as part of the Global Fireball Observatory (GFO) recorded a 3.2 s fireball on March 8, 2022 at 8:15 p.m. UTC. A meteoroid of 4 ± 2 kg entered the atmosphere at 14.0 km/s.

Strong Proton‐Phonon Coupling Drives Fast Ion Transport in Perovskites
Advanced Science, Volume 13, Issue 9, 13 February 2026.Experimental and computational phonon analysis of ABO3‐type proton conductor BaSnO3 shows that substitution on the B‐site with yttrium forms an imaginary phonon mode which is instrumental for the function as proton conductor. This overcompensates the adverse proton trapping effect of the yttrium.

Long-term Monitoring of Scintillation in the Pulsar J0332+5434
The Astrophysical JournalChanges in a pulsar’s scintillation characteristics over time can be a useful way to probe the properties of the interstellar medium. Monitoring the scintillation bandwidth can be useful for correcting for scattering delay in pulse arrival time, which ...

Morphology of Antarctic Polygons and Implications for Polygon Evolution and Subsurface Ice Dynamics
Permafrost and Periglacial Processes, Volume 37, Issue 1, Page 143-153, January/March 2026.ABSTRACT Polygonal terrain results from thermal contraction, is commonly found in periglacial environments, and serves as a valuable proxy for interpreting subsurface ice distribution and climate history on Earth and Mars. In this study, we investigate the morphology of polygons in Beacon Valley, Antarctica, to assess the relationship between polygon ...
