Research on the direction estimation algorithm of vector hydrophones under near-field and Far-field Reflecting Boundary

International Journal of Metrology and Quality Engineering
To address the impact of reflection boundaries and port and starboard ambiguity on passive sonar positioning, a method of vector hydrophone hybrid source positioning under different reflection boundaries is proposed. When the reflection boundary is close

Real Options under Choquet-Brownian Ambiguity [PDF]

Real options models characterized by the presence of ambiguity have been recently proposed. But based on recursive multiple-priors approaches to solve ambiguity, these seminal models reduce individual preferences to extreme pessimism by considering only ...

Pervasively Thin Anatolian Lithosphere With Elevated Upper Mantle Temperatures in the East: Insights From Bayesian Thermo‐Compositional Inversion

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract Uplift and widespread Late Miocene‐present magmatism in Anatolia are commonly attributed to lithospheric thinning, possibly facilitated by the arrival of hot mantle plume material. There are various lines of evidence for thin present‐day lithosphere, but the spatial extent and degree of lithospheric thinning and the underlying mantle ...

Combining Borehole Seismic Data and Deep‐Learning Methods to Monitor Seismic Sequences in the Istanbul‐Marmara Region, NW Türkiye

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract The North Anatolian Fault Zone beneath the Sea of Marmara in NW Türkiye displays a 50% probability of an M≥7 $\mathrm{M}\ge 7$ earthquake within the next decades. The proximity of the fault to the Istanbul megalopolis highlights the need for high‐resolution microseismicity monitoring to identify seismicity transients including pre‐mainshock ...

Ambiguity and Social Interaction [PDF]

We present a non-technical account of ambiguity in strategic games and show how it may be applied to economics and social sciences. Optimistic and pessimistic responses to ambiguity are formally modelled.

Tracking Slow‐Moving Landslide Responses to the 2023 Kahramanmaraş Earthquake With InSAR

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 10, October 2026.
Abstract Strong earthquakes can have a dual impact on the slow‐moving landslide budget of a landscape by either triggering new actively deforming hillslopes or stabilizing existing ones. However, their regional‐scale influence on hillslope processes remains poorly understood because of limited observational coverage and the masking effects of long ...

ScintPi 4.0: A New GNSS‐Based Low‐Cost, Multi‐Constellation, Multi‐Frequency Ionospheric Scintillation and TEC Monitor for Education, Citizen Science, and Research Initiatives

Space Weather, Volume 24, Issue 10, October 2026.
Abstract ScintPi is a series of alternative ionospheric scintillation and total electron content (TEC) monitors. ScintPi monitors have been built by combining single‐board computers (Raspberry Pi) and commercial off‐the‐shelf (COTS) Global Navigation Satellite System (GNSS) receivers.

A Gaussian Process Regression Framework for Slant Ionospheric Delay Interpolation and Uncertainty Quantification With Applications to PPP‐RTK

Space Weather, Volume 24, Issue 10, October 2026.
Abstract Reliable slant ionospheric information is crucial for Precise Point Positioning Real‐time Kinematic (PPP‐RTK), yet its correction in low‐latitude regions remains difficult because of ionospheric variability, observable anomalies, and insufficiently reliable uncertainty characterization.

Overlapping Azimuth Channels for SAR Imaging --- Revisited [PDF]

Digital beamforming in combination with multiple azimuth channels (MACs) enable high azimuth resolution Synthetic Aperture Radar (SAR). In terms of the SAR trade space this comes at the expense of restricting the instrument Pulse Repetition Frequency ...

Active Normal Fault Segmentation and Linkage in the Umbria‐Marche Apennines (Italy): Insights From 3D Structural Modeling

Tectonics, Volume 45, Issue 10, October 2026.
Abstract Normal‐fault growth, segmentation, and their relationships with crustal inheritance and rheological layering are investigated in a post‐thrusting setting of the southern sector of the Northern Apennines. We integrate 3D modeling with gravity, thermal, and seismological constraints to reconstruct the geometry and evolution of the main normal ...
