Simulating Bouncing Packets Driven by Ducted Lightning‐Generated Whistlers: Comparison With SAMPEX Observations

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Bouncing packets are quasi‐periodic microbursts separated by the electron bounce period. Solar Anomalous and Magnetospheric Particle Explorer observations revealed relativistic (>1 MeV) inner‐belt bouncing packets with “crown,” “decaying,” and “flat” envelopes.

Early Eocene Compressional Deformation in the Northeastern Tibetan Plateau Recorded by Magnetic Fabrics of the Longzhong Basin

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Intracontinental deformation records how early Eocene India–Asia collisional stress propagated into continental interiors. How rapidly compression reached the far field, and whether coeval Paleo‐Pacific slab dynamics contributed, remain debated. The Longzhong Basin, ∼1,900 km north of the collisional zone, provides a key test.

A theoretical analysis of the logging-while-drilling dipole acoustic reflection measurement

open access: yesFrontiers in Earth Science
Post-drilling wireline acoustic single-well imaging technology can now detect geological structures tens of meters away from boreholes. Further development of this single-well imaging technology in the logging-while-drilling (LWD) environment will have ...

Listening to Tsunami Waves Induced by Glacier Calving

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Processes at the ice–ocean interface play a central role in regulating the stability of marine‐terminating glaciers and ice sheets and drive ocean freshening and mixing. Iceberg calving—a mechanical loss of ice—generates ocean waves and promotes water‐mass exchange in glacierized bays.

Oxygen‐Vacancy‐Regulated Crystallization and Ferroelectric Phase Stabilization in Hf0.5Zr0.5O2 Thin Films

open access: yesAdvanced Functional Materials, Volume 36, Issue 77, 24 September 2026.
Temperature‐resolved in situ grazing‐incidence wide‐angle X‐ray scattering reveals that oxygen vacancies actively regulate crystallization in Hf0.5Zr0.5O2 thin films. By decoupling macroscopic strain from intrinsic phase evolution, a vacancy‐lean environment significantly lowers the activation energy barrier for crystallization.

Confidence and ambiguity [PDF]

open access: yes
This paper proposes a model of the decision-maker’s confidence in his probability judgements, in terms of an implausibility measure – a real-valued function on the set of probability functions.

1‐D Collocated Dual‐Gradient Sensory Fibers for Comprehensive Sensing and Decoding of Complex Human Motion and Physiology

open access: yesAdvanced Materials, Volume 38, Issue 53, 21 September 2026.
Coupled materials design enables a monolithic fiber that integrates complementary sensing regimes into a single wearable strand. By preserving informative signal features across subtle physiological deformation, large body motion, and mixed mechanical inputs, the dual‐gradient architecture generates synchronized, less redundant outputs that improve ...

AVOA technique for fracture characterization: resolving ambiguity [PDF]

open access: yesGeofísica Internacional, 2008
A new computational technique of AVOA analysis (Amplitude Versus Offset and Azimuth) is developed which resolves an ambiguity in fracture-direction estimation.

Rational Preferences under Ambiguity [PDF]

open access: yes
This paper analyzes preferences in the presence of ambiguity that are rational in the sense of satisfying the classical ordering condition as well as monotonicity.
