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.

Alteration of Feldspar‐Rich Rocks on Ancient Mars and Its Possible Link to Ca/Fe‐Rich Carbonates

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Feldspar‐rich rocks have increasingly been discovered on the martian surface. They may have been an important part of the ancient martian crust and may be related to Ca/Fe‐rich carbonates (one of two types of carbonates on Mars and the other being Mg‐rich carbonates), but compared to mafic rocks, their interaction with water on ancient Mars is

Thermodynamic Constraints on H2 Production and Habitability From Mg‐Rich Serpentinites as Mars Analogs

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Serpentinization produces hydrogen and methane through abiotic water‐rock interactions, potentially supporting chemotrophic life in planetary subsurface environments. Serpentine deposits in the Martian Noachian landscapes of Nili Fossae and the Southern Highlands have been considered as potential paleo‐habitable zones. However, the geochemical

Long-term Monitoring of Scintillation in the Pulsar J0332+5434

The Astrophysical Journal
Changes 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 ...

Evolutionarily Optimal Risk Aversion

Risk Analysis, Volume 46, Issue 5, May 2026.
ABSTRACT In an experimental choice situation, we identify risk‐acceptability thresholds and show how such thresholds are updated in response to benchmark information, a recurrent feature of health, safety, and environmental (HS&E) risk governance. We present a theoretical framework linking the observed behavior to an underlying evolutionary parameter ...
