The Unexploited Treasures of Hydrological Observations Beyond Streamflow for Catchment Modeling

WIREs Water, Volume 12, Issue 2, March/April 2025.
Caption: In situ and satellite‐based observations of hydrological variables beyond streamflow are valuable to improve modeling catchment hydrology (modified from Fisher 2005; CC BY‐SA 4.0). ABSTRACT While measured streamflow is commonly used for hydrological model evaluation and calibration, an increasing amount of data on additional hydrological ...

Enhancement of SAR Image Resolution with Implementation of Circular GB-SAR System

, 2013
Radars were used for surveillance and remote sensing but nowadays they handle a vast range of applications, radar imagery being one of them. The need for high resolution images was inevitable which lead to Synthetic Aperture Radar (SAR) systems.

Modern machine‐learning for binding affinity estimation of protein–ligand complexes: Progress, opportunities, and challenges

WIREs Computational Molecular Science, Volume 14, Issue 3, May/June 2024.
Machine‐learning scoring functions have to be discussed in the context of their featurization strategy, their machine‐learning approach, and their predictive task and are influenced by explainability and dataset choices. Abstract Structure‐based drug design is a widely applied approach in the discovery of new lead compounds for known therapeutic ...

Molecular Investigation of SARS‐CoV‐2 Circulating in Iranian Bats Using Real‐Time RT‐PCR for Detection of Envelop (E) Gene of the Virus

Transboundary and Emerging Diseases, Volume 2024, Issue 1, 2024.
Background. The COVID‐19 was first reported in 2019 to cause pneumonia in people of Wuhan, Hubei province, China, is now associated with high mortality worldwide. Phylogenetic analysis revealed that SARS‐CoV‐2 (2019‐nCoV) is closely (88%–89% similarity) related to the coronavirus circulating in Rhinolophus (horseshoe bats).

Exploiting Projection Trajectories Discrepancy for Multipath Suppression and Detailed Feature Extraction of Buildings in SAR Adjacent Sub-Aperture Images

Remote Sensing
In synthetic aperture radar (SAR) imagery of built-up areas, multipath effects generate false targets that closely resemble genuine structural features, severely hindering refined interpretation of building structures.

Fast circular aperture synthesis in sar all-aspect target imaging

, 2008
The objective of this research is a fast circular synthetic aperture radar (F-CSAR) algorithm. Slow-time imaging distinguishes synthetic aperture radar (SAR) from its predecessor imaging radars. SAR slow-time imaging is strongly rooted in Huygens-Fresnel

3D Point Cloud Reconstruction Using Inversely Mapping and Voting from Single Pass CSAR Images

, 2021
3D reconstruction has raised much interest in the field of CSAR. However, three dimensional imaging results with single pass CSAR data reveals that the 3D resolution of the system is poor for anisotropic scatterers.
