Introduction to TREx‐ATM V2.0: A Versatile Model of Auroral Transport and Its Effects in the Ionosphere

open access: yesEarth and Space Science, Volume 13, Issue 7, July 2026.
Abstract Auroral transport models (ATMs) play an important role in quantitative studies of optical auroras, their driving mechanisms, and their effects on the ionosphere and thermosphere. TREx‐ATM was initially developed as the support model for the Transition Region Explorer (TREx) mission, and has gained increasing applications in the community in ...

Picone's identity for the p-biharmonic operator with applications

open access: yesElectronic Journal of Differential Equations, 2011
In this article, a Picone-type identity for the weighted p-biharmonic operator is established and comparison results for a class of half-linear partial differential equations of fourth order based on this identity are derived.

How the 29 July 2025 M8.8 Kamchatka Earthquake Shook the Ionosphere Over Japan

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.
Abstract This study investigates the mid‐field (∼1,100–3,800 km) ionospheric response to the 29 July 2025 Kamchatka earthquake over Japan using multi‐instrument observations, raytracing, and numerical simulations. Total electron content (TEC) observations from GPS satellite G04 and Galileo satellite E10 show a maximum TEC perturbation of ∼0.5–0.85 TECU

Picone's identity and the moving plane procedure

open access: yesElectronic Journal of Differential Equations, 1995
Summary: Positive solutions of a class of nonlinear elliptic partial differential equations are shown to be symmetric by means of the moving plane argument coupled with spectral theory results and Picone's identity. The method adapts easily to situations where the moving plane procedure gives rise to variational problems with positive eigenfunctions.

High Latitude Thermosphere and Ionosphere Density Response to the May 2024 Geomagnetic Storm Observed by the LLITED CubeSat Mission

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.
Abstract The May 2024 G5 geomagnetic storm produced significant disturbances in the ionosphere and thermosphere, particularly at high latitudes. Using high‐resolution in situ ion and neutral density measurements from the NASA Low‐Latitude Ionosphere/Thermosphere Enhancements in Density (LLITED) CubeSat at 430 km altitude, this study documents notable ...

Oscillation for quasilinear elliptic equations with p(x)-Laplacians in general domains

open access: yesElectronic Journal of Differential Equations, 2013
Oscillation of quasilinear elliptic equations with p(x)-Laplacians in general domains are derived by the variational approach as applications of Picone identity. Three examples are given, and generalizations to quasilinear elliptic equations with $p(x)

New‐Onset Vitiligo During Dupilumab Treatment: A Clinical Observation and Literature Review

open access: yesThe Clinical Respiratory Journal, Volume 20, Issue 7, July 2026.
Dupilumab rarely induces new‐onset vitiligo, even after discontinuation of the drug, potentially through the activation of the Th1/IFN‐γ pathway following IL‐4R blockade. Female sex and the use of topical corticosteroids are associated with improved outcomes, whereas discontinuing dupilumab alone does not ensure repigmentation.

Generalized Picone and Riccati inequalities for half-linear differential operators with arbitrary elliptic matrices

open access: yesElectronic Journal of Differential Equations, 2010
In the article, we extend the well-known Picone identity for half-linear partial differential equations to equations with anisotropic p-Laplacian.

The roles of multinational enterprises in governing the sustainability of global supply chains

open access: yesInternational Journal of Management Reviews, Volume 28, Issue 3, July 2026.
Abstract An extensive but fragmented body of research shows that multinational enterprises (MNEs) engage with multiple sustainability rules in global supply chains (GSCs) spanning the private, social and public governance sectors. MNEs perform diverse roles by either shaping or complying with these rules.

Multi‐Step Gravity Wave Propagation From a Tropospheric Vortex to the Ionosphere Near the Tibetan Plateau

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The atmosphere and ionosphere form a vertically coupled system in which disturbances in the lower atmosphere can modulate ionospheric variability. Using reanalysis data, ground‐based GNSS observations, and COSMIC‐2 profiles, we investigate gravity waves (GWs) generation and upward coupling during a southwest vortex (SWV) event over the Tibetan
