Sentinel-1 data exploitation for terrain deformation monitoring

open access: yes, 2023
Persistent Scatterer interferometry (PSI) is a group of advanced differential interferometric Synthetic Aperture Radar (SAR) techniques used to measure and monitor terrain deformation. Sentinel-1 has improved the data acquisition throughout and, compared to previous sensors, increased considerably the Differential Interferometric SAR (DInSAR) and PSI ...

Snow Depth Variability in the Northern Hemisphere Mountains Observed from Space [PDF]

open access: yes, 2019
Accurate snow depth observations are critical to assess water resources. More than a billion people rely on water from snow, most of which originates in the Northern Hemisphere mountain ranges.

Portraying the Need for Temporal Data in Flood Detection via Sentinel-1 [PDF]

open access: yesarXiv
Identifying flood affected areas in remote sensing data is a critical problem in earth observation to analyze flood impact and drive responses. While a number of methods have been proposed in the literature, there are two main limitations in available flood detection datasets: (1) a lack of region variability is commonly observed and/or (2) they ...

Longitudinal Change in Bone Density, Geometry, and Estimated Bone Strength in Older Men and Women From The Gambia: Findings From the Gambian Bone and Muscle Aging Study (GamBAS)

open access: yesJournal of Bone and Mineral Research, Volume 38, Issue 1, Page 48-58, January 2023., 2023
ABSTRACT Musculoskeletal aging in the most resource‐limited countries has not been quantified, and longitudinal data are urgently needed to inform policy. The aim of this prospective study was to describe musculoskeletal aging in Gambian adults. A total of 488 participants were recruited stratified by sex and 5‐year age band (aged 40 years and older ...

A light-weight model to generate NDWI from Sentinel-1 [PDF]

open access: yesarXiv
The use of Sentinel-2 images to compute Normalized Difference Water Index (NDWI) has many applications, including water body area detection. However, cloud cover poses significant challenges in this regard, which hampers the effectiveness of Sentinel-2 images in this context.

Emergent Cardiac Surgery After Transcatheter Structural Heart Procedures: Narrative Review

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Transcatheter structural heart procedures have become standard therapy for elderly patients with high surgical risk. Over time, these procedures have significantly increased worldwide, accompanied by a concomitant reduction of major complications, including those requiring emergent cardiac surgery (ECS).

The appearance of phagocytic microglia in the postnatal brain of Niemann Pick type C mice is developmentally regulated and underscores shortfalls in fine odor discrimination

open access: yesJournal of Cellular Physiology, Volume 237, Issue 12, Page 4563-4579, December 2022., 2022
Abstract The loss of NPC1 or NPC2 function results in cholesterol and sphingolipid dyshomeostasis that impairs developmental trajectories, predisposing the postnatal brain to the appearance of pathological signs, including progressive and stereotyped Purkinje cell loss and microgliosis.
