Cross‐Prudence and Optimal Prevention
International Economic Review, EarlyView.ABSTRACT In this paper, we study optimal prevention in the presence of a correlated nonfinancial background risk. Under positive correlation, cross‐prudence in the nonfinancial attribute reduces optimal prevention. We establish this result in the most direct extension of the standard prevention problem with binary marginal distributions and show that ...

Earth and Space Science, Volume 13, Issue 10, October 2026.Abstract Atmospheric refractivity model accuracy is important for refraction correction, starlight refraction navigation, and related optoelectronic applications. To address the insufficient understanding of refractivity temporal evolution and the lack of clear criteria for selecting model temporal resolution, this study constructs a global four ...

Chorus Wave‐Induced Ionospheric Variability
Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Electron microbursts are short‐lived but intense electron precipitation and constitute a significant source of electron losses into the ionosphere and lower atmosphere. They are primarily produced by wave‐particle interaction with chorus waves in the magnetosphere.

Beyond Tobacco Prevention: The Effects of Tobacco 21 Laws on Young Adults' Body Weight
Health Economics, Volume 35, Issue 9, Page 1406-1423, September 2026.ABSTRACT Tobacco 21 (T21) laws effectively reduce youth tobacco use by preventing initiation. This study examines their impact on body weight among young adults aged 18–20. Using 2009–2019 Behavioral Risk Factor Surveillance System data and a two‐way fixed‐effects difference‐in‐differences (DID) design, we find limited evidence of broad weight changes ...

Predicting net N mineralized from soil organic matter under fluctuating environmental conditions
Soil Science Society of America Journal, Volume 90, Issue 5, September/October 2026.Abstract Nitrogen mineralization from soil organic matter can provide substantial amounts of N for growing crops. However, it is often overlooked or poorly estimated due to the limited availability of rapid soil tests. We conducted a study to (1) fit first‐ and zero‐order N kinetics models to long‐term N mineralization data from 29 US soils, (2 ...

Generalized Picone identity for Finsler -Laplacian and its applications
Ukrains’kyi Matematychnyi Zhurnal, 2021 UDC 517.9 We prove a generalized Picone-type identity for Finsler -Laplacian and use it to establish some qualitative results for some boundary-value problems involving Finsler -Laplacian.

The Daily Atmospheric Ionospheric Limb Imager (DAILI) CubeSat Experiment
Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.Abstract The Daily Atmospheric Ionospheric Limb Imager (DAILI) (Daily Atmospheric and Ionospheric Limb Imager) mission utilized a 6U CubeSat, deployed at about 410 km altitude in a 51‐degree orbit, to make simultaneous daytime limb measurements in two colors; at 630 nm to measure the OI (630 nm) redline and at 765 nm to measure the O2 ${\mathrm{O}}_{2}$

Acoustic Wave Signatures of Earthquake Rupture Dynamics in the Upper Atmosphere
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.Abstract We perform three‐dimensional coupled earthquake‐atmosphere numerical simulations that integrate dynamic rupture, seismic wave propagation, and a compressible nonlinear atmospheric model to investigate how earthquake source parameters influence acoustic wave (AW) characteristics at 100–300 km altitude in the thermosphere.

Picone's Identity and the Moving Plan Procedure [PDF]
, 1995 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.
