Ship and Oil-Spill Detection Using the Degree of Polarization in Linear and Hybrid/Compact Dual-Pol SAR [PDF]

open access: yes, 2012
Monitoring and detection of ships and oil spills using synthetic aperture radar (SAR) have received a considerable attention over the past few years, notably due to the wide area coverage and day and night all-weather capabilities of SAR systems.

Assessment of L-Band and C-Band SAR on Burned Area Mapping of Multiseverity Forest Fires Using Deep Learning

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Earth observation-based burned area mapping is critical for evaluating the impact of wildfires on ecosystems. Optical satellite data from Landsat and Sentinel-2 are often used to map burned areas.

Liver organoids: modelling complexity in homeostasis and disease

open access: yesFEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

Forest above-ground biomass estimation using X, C, L, and P band SAR polarimetric observations and different inversion models

open access: yesInternational Journal of Digital Earth
Since each frequency senses distinct features of forest structure, it is attractive to understand whether complementarity of multi-frequency can improve the retrieval of forest above ground biomass (AGB).

Imaging of targets beneath foliage with SAR tomography [PDF]

open access: yes, 2008
SAR tomography (SARTom) is an imaging technique that allows multiple phase centre separation in the vertical (height) direction, leading to a 3-dimensional (3D) reconstruction of the imaged scene. It is usually performed after standard 2D SAR repeat-pass

Multi-temporal high-resolution polarimetric L-band SAR observation of a wine-producing landscape [PDF]

open access: yes, 2006
In continuation of the BACCHUS project, aimed at establishing a reference high quality geographic information system for vineyards, an airborne SAR survey has been carried out in fall 2005 in the Frascati area, near Rome (Italy) to demonstrate the ...

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

open access: yesFEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

L-band Airborne Repeat-pass Interferometric SAR System and Its Experimental Study

open access: yesLeida xuebao, 2019
This paper describes the L-band airborne Synthetic Aperture Radar (SAR) system and an experimental study of repeat-pass SAR interferometry. The discussions mainly focus on the internal calibration method, the imaging method based on Differential Global ...

Comparison of Three Methods for Distinguishing Glacier Zones Using Satellite SAR Data

open access: yesRemote Sensing, 2023
Changes in glacier zones (e.g., firn, superimposed ice, ice) are good indicators of glacier response to climate change. There are few studies of glacier zone detection by SAR that are focused on more than one ice body and validated by terrestrial data ...
