Author Correction: Harmonic phase in polar liquids and spin ice

Nature Communications, 2018
The original version of this Article contained an error in the third sentence of the penultimate paragraph of the ‘Definition of the harmonic phase’ section of the Results, which incorrectly read ‘In the Coulomb phase the tensor S αβ (q) has one zero and

Magnetic properties of geraisites, the first tektite strewn field identified in Brazil

Meteoritics &Planetary Science, Volume 61, Issue 7, Page 1163-1178, July 2026.
Abstract Geraisites are a newly recognized class of tektite from Brazil. They occur as centimeter‐sized, elongated to subspherical bodies scattered across surface gravel and shallow subsurface layers within a ~90‐km‐long strewn field extending between the municipalities of São João do Paraíso and Curral de Dentro, near the border between the states of ...

An Analysis of Hurricane Eyewall Ice Using a Novel Lagrangian Trajectory and Growth Model

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract Ice crystals in tropical cyclones (TCs) remain infrequently observed and difficult to model using Eulerian microphysics parameterizations. To better understand TC eyewall ice crystal processes, the Ice Crystal Trajectory Growth (ICTG) model, previously applied to an idealized squall line, was used to simulate Lagrangian ice crystal ...

Rock Physics of the Critical Zone: Models, Inversion, and Interpretation

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Rock physics models link geophysical measurements with subsurface petrophysical properties, such as porosity, mineral composition, and fluid saturation. While originally developed for hydrocarbon exploration, these models are increasingly applied in the near surface for quantitative interpretation of geophysical data.

A Theoretical Study of Indentation with an Oblate Spheroid Shape

, 2016
In this study, firstly we introduced general mathematical concepts related to the geometrical form of ellipse and ellipsoid. Secondly, the hardness was calculated when we used an indenter having a geometrical shape of an oblate spheroid; the ...

Existence of Resonance Stability of Triangular Equilibrium Points in Circular Case of the Planar Elliptical Restricted Three-Body Problem under the Oblate and Radiating Primaries around the Binary System

Advances in Astronomy, 2014
This paper analyzes the existence of resonance stability of the triangular equilibrium points of the planar elliptical restricted three-body problem when both the primaries are oblate spheroid as well as the source of radiation under the particular case,
