SilberPrime/infrasound-signal-arrival-azimuth: v2.7.1

open access: yes, 2021
This release includes the Matlab functions that calculate the infrasound signal arrival parameters: distance in km and degrees, back azimuth, and arrival times for three main propagation channels (tropospheric, stratospheric, thermospheric ...

Topology‐based Visual Analysis of Hydrothermal Plumes

open access: yesComputer Graphics Forum, EarlyView.
Abstract Hydrothermal plumes are turbulent structures of intense heat and mineral smoke that rise and disperse into the deep ocean. Existing models generally characterize these systems as a single axisymmetric plume originating from a point source. However, this assumption breaks down in weakly venting, spatially distributed systems, where low‐flux ...

The Truth, the Whole Truth, and Nothing but the Truth: Automatic Visualization Evaluation from Reconstruction Quality

open access: yesComputer Graphics Forum, EarlyView.
Abstract Recent advances in AI enable the automatic generation of visualizations directly from textual prompts using agentic workflows. However, visualizations produced via one‐shot generative methods often suffer from insufficient quality, typically requiring a human in the loop to refine the outputs.

Azimuth

open access: yes, 2007
The exhibition,"Azimuth", looks at earth and space in a series of visually spectaculor works by the two artists. Daniel Armstrong’s series of digital photographs are heavily manipulated grids of astronomical images sampled from the night sky with time ...

US Influence in Post‐Assad Syria and the Limits of Turkey's Leverage

open access: yesMiddle East Policy, Volume 33, Issue 4, Winter 2026.
Abstract In early 2026, the post‐Assad government in Damascus weakened the Kurdish‐led Syrian Democratic Forces (SDF) and began integrating the group through phased incorporation and gradual reassertion of state authority. While this advanced some Turkish objectives, it demonstrated the limits of Ankara's influence: Kurdish fighters were incorporated ...

Outcrop and subsurface characterisation of a mixed tidal and wave‐influenced coastline (Triassic Red Beds, SE Spain)

open access: yesSedimentology, Volume 73, Issue 6, Page 2381-2416, October 2026.
ABSTRACT Paralic depositional systems are complex and heterogeneous sedimentary environments, presenting challenges for predicting reservoir architecture and connectivity. Their stratigraphic and facies variability arises from the dynamic interplay between fluvial, tidal and wave processes, and their sensitivity to sea‐level fluctuations, sediment ...

Crustal Shear‐Wave Velocity and Azimuthal Anisotropy Imaging Reveals the Merapi‐Merbabu‐Telomoyo Volcanic Chain, Central Java

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract We present new results from ambient noise tomography and azimuthal anisotropy analysis of the DOMERAPI data set to investigate crustal structure beneath the Merapi‐Merbabu‐Telomoyo region in central Java. The 3D shear‐wave velocity (Vs) model reveals a prominent high‐Vs anomaly extending from south of Merapi through Merbabu to Telomoyo ...

Special MISO-SAR and MIMO-SAR Modes for Bidirectional Imaging

open access: yesInternational Journal of Antennas and Propagation, 2014
The paper proposes special multiple-input single-output synthetic aperture radar (MISO-SAR) and multiple-input multiple-output SAR (MIMO-SAR) for bidirectional imaging, which can simultaneously illuminate two areas from different directions in azimuth ...

A Novel Azimuth Doppler Signal Reconstruction Approach for the GEO-LEO Bi-Static Multi-Channel HRWS SAR System

open access: yesIEEE Access, 2019
For the geosynchronous-low earth orbit (GEO-LEO) bi-static multi-channel high-resolution and wide-swath synthetic aperture radar (HRWS SAR) system, a novel azimuth Doppler signal reconstruction algorithm is developed based on an equivalent baseline ...

Association of Picket‐Fence With Auroral Continuum Emissions

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract We present observations of aurora‐like “picket‐fence” emissions occurring simultaneously with broad‐band auroral continuum emission structures. The continuum structures exhibit spectral properties similar to the Strong Thermal Emission Velocity Enhancement (STEVE), but appear at higher latitudes, alongside the aurora.
