OBS Data Mining Reveals Seismic Structure and Dynamics of the Oceanic Blanco Transform Fault, Northeast Pacific

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Deformation along oceanic transform faults is partitioned between seismic and aseismic slip, controlled by lithology, thermal structure, and fluid circulation. We analyze one year of data from a 54‐station ocean bottom seismometer network deployed across the Blanco Transform Fault (BTF), Northeast Pacific.

Regge behavior saves string theory from causality violations [PDF]

open access: yes, 2015
Higher-derivative corrections to the Einstein-Hilbert action are present in bosonic string theory leading to the potential causality violations recently pointed out by Camanho et al.

Establishment and validation of a hair fall atlas for Chinese men based on trichoscopy

open access: yesInternational Journal of Cosmetic Science, Volume 48, Issue 3, Page 657-666, June 2026.
A new hair fall atlas with 7 scales is established and validated and ready to publish as a new methodology. We observed good consistency between the dermatologists' grading (PCC >0.8), and a strong correlation shown between clinical scores and hair fall attributes based on image analysis (|p| > 0.8).

Hunga‐Tonga Volcano Plumbing System Inferred From Virtual Seismometer Approach

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract We present a surface wave tomography application based on event‐pair interferometry to investigate local (∼100 km) mid‐ocean crustal structures, with a particular focus on imaging a potential crustal solidified intrusive complex in a region lacking seismic stations.

Eikonal theory of electron-atom collisions

open access: yes, 1973
The application of eikonal methods to electron-atom scattering is reviewed. After recalling the basic features of the eikonal approximation, we discuss the Glauber theory, the eikonal-Born series method, the eikonal optical model theory and the eikonal ...

Eikonal perturbation theory in photoionization

open access: yes, 2016
The eikonal perturbation theory is formulated and applied to photoionization by strong laser pulses. A special emphasis is put on the first order approximation with respect to the binding potential, which is known as the generalized eikonal approximation

Representation Formula for Solutions of Eikonal Type Equations

open access: yesNonlinear Analysis, 2001
Equations of an eikonal type ones arise in many areas of applications, including optics, fluid mechanics, material sciences, and control theory. This article investigates the representation formula for semiconcave solutions of the boundary problem for ...

EIKONAL* R. Jackiw, D. Kabat

open access: yes, 2007
Electromagnetic fields of a massless charged particle are described by a gauge potential that is almost everywhere a pure gauge. Solution of quantum mechanical wave equations in the presence of such fields is therefore immediate and leads to a new ...

Second-order eikonal corrections for A(e, e ' p)

open access: yes, 2007
The first-order eikonal approximation is frequently adopted in interpreting the results of A(e,e′p) measurements. Glauber calculations, for example, typically adopt the first-order eikonal approximation.
