Design and Implementation of an Automated Wheelchair With Voice and Gesture Control, Obstacle Avoidance, and Real‐Time Location Sharing

open access: yesEngineering Reports, Volume 8, Issue 11, November 2026.
This work presents a standalone smart wheelchair featuring dual voice‐ and gesture‐based control, obstacle avoidance, and real‐time location sharing. The system achieves 100% gesture accuracy and 94% voice accuracy, enabling safe, independent mobility for users with severe physical impairments and providing emergency support without smartphone ...

Dynamic Cell Division for Interference Management in Satellite Direct‐to‐Cell Systems

open access: yesInternational Journal of Satellite Communications and Networking, Volume 44, Issue 6, Page 757-765, November/December 2026.
ABSTRACT Direct‐to‐cell (D2C) connectivity enables future non‐terrestrial networks to provide service directly to standard terrestrial user equipment (UE) when terrestrial networks (TN) are unavailable. In this work, the satellite system is considered as a secondary network that supplements existing TN coverage while minimizing interference to the ...

Do Shallow Slip Deficits Reflect Fault Structural Maturity or Modeling Choices? A Comparative Analysis of Tibetan Strike‐Slip Earthquakes

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract InSAR‐constrained finite fault slip models are often used to characterize fault geometries and slip distributions of large continental earthquakes. A common feature of these models is a decrease in slip near the surface, commonly expressed as a percentage shallow slip deficit (SSD).

Widespread On‐Fault Geologic Evidence for Variable Mode Coseismic Slip to the Trench in Cascadia

open access: yesAGU Advances, Volume 7, Issue 8, November 2026.
Abstract Investigating the geologic record of near‐trench coseismic strain release is critical for estimating the slip distribution and tsunamigenic potential of future large subduction zone earthquakes. However, the style and extent of upper plate coseismic deformation offshore in subduction zones is poorly constrained.

Assessment of NAPGD2022's Performance in Oregon's Willamette Valley Using Astronomical Leveling and GNSS/Leveling

open access: yesEarth and Space Science, Volume 13, Issue 11, November 2026.
Abstract The North American‐Pacific Geopotential Datum of 2022 (NAPGD2022) is anticipated to become the official height system of the United States in 2027. This new datum is realized through a suite of models, including GEOID2022 (geoid) and DEFLEC2022 (deflection of the vertical).

From Fault Ruptures to Atmospheric Perturbations: Examining the 2016 Norcia Seismic Sequence

open access: yesEarth and Space Science, Volume 13, Issue 11, November 2026.
Abstract This study investigates lithosphere–atmosphere interactions during the 2016 Central Italy seismic sequence, providing the first systematic analysis of atmospheric impacts across the entire series within a complex tectonic setting. The static displacement fields of the main events were modeled using the Okada formulation and validated against ...

Hydrothermal Sealing at Turrialba, Poás, and Rincón de la Vieja Volcanoes (Costa Rica) Promotes Phreatic and Phreatomagmatic Eruptions

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract Hydrothermal sealing is a mechanism thought to be responsible for challenging‐to‐forecast phreatic and phreatomagmatic eruptions. To better understand this process, we present a study in which we assessed the textural, mineralogical, and physical properties (porosity, permeability, and tensile strength) of blocks of hydrothermal seal that were
