Broadband complex permittivity spectroscopy for particulate media: Soil characterization in high water content

Soil Science Society of America Journal, Volume 90, Issue 4, July/August 2026.
Abstract Broadband complex permittivity spectroscopy enables characterization of the frequency‐dependent electrical behavior of wet particulate media. Conventional field methods, including microwave‐based techniques and time‐domain reflectometry (TDR), rely on apparent permittivity over limited or implicit frequency ranges, restricting their ability to

Response characteristics of ground-penetrating radar for subgrade void based on random reconstruction of soil-rock mixture

Yantu gongcheng xuebao
In order to study the response characteristics of geological radar waves to soil-rock mixed subgrade void, a microscopic model of soil-rock mixture with pores is built with considering the randomness and non-uniformity of soil-rock mixtures.

Reinterpreting the Recurrence Time–Moment Relation of Global Repeating Earthquakes: A Scattered Data Cloud Bounded by Crack‐Model Physics

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Repeating earthquakes are recurrent ruptures of the same asperity along creeping faults, and their recurrence time–moment (Tr ${T}_{r}$–M0 ${M}_{0}$) scaling provides key constraints on earthquake physics and fault creep. However, previous studies have reported Tr∝M01/6 ${T}_{r}\,\propto \,{M}_{0}^{1/6}$, seemingly inconsistent with the ...

Seismo‐Acoustic Characterization and Array Processing of Dry‐ and Wet‐Snow Avalanches

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 7, July 2026.
Abstract Snow avalanches generate complex seismic and infrasound signals influenced by terrain, snow properties, flow regime, and avalanche size. In this controlled field study, we analyzed the seismo‐acoustic characteristics of three avalanches that released along the same path in the Dischma valley above Davos, Switzerland.

Effects of Wintertime Snow Depth Assimilation on Summertime Sea Ice Prediction Experiments Utilizing a Fully Coupled Regional Arctic Model With Perfect Boundary Conditions

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.
Abstract During the past decades, the rapid decline of sea ice in the Arctic Ocean has substantially favored commercial navigation activities in the summertime. Numerical sea ice prediction on a seasonal scale plays a crucial role in guiding the programme of such activities, yet the role of snow depth data assimilation in numerical sea ice prediction ...

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

Journal 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

Assimilation of Satellite‐Based Forest Biomass, Productivity and Leaf Area Index in a Global Land Model Incorporating Parameter Spatial Variations and Age Effects

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.
Abstract Disturbances profoundly impact forest capacity for sequestering and storing carbon, and the recovery rates after disturbances vary geographically. Many terrestrial carbon models inadequately simulate the effects of forest disturbances on biomass due to their reliance on equilibrium assumptions, the absence of historical disturbance data, as ...

Adolescents and Adults Use Different Facial Movements and Vocal Cues to Express Emotions

Developmental Science, Volume 29, Issue 4, July 2026.
ABSTRACT Current understanding of how facial and vocal cues can communicate emotional intent is based on patterns observed in adults, with surprisingly little known about age‐related differences in nonverbal expression. Do adolescents and adults use different nonverbal cues to express emotions? This cross‐sectional laboratory study revealed age‐related
