Differentiable SAR Renderer and SAR Target Reconstruction

CoRR, 2022
Forward modeling of wave scattering and radar imaging mechanisms is the key to information extraction from synthetic aperture radar (SAR) images. Like inverse graphics in optical domain, an inherently-integrated forward-inverse approach would be promising for SAR advanced information retrieval and target reconstruction.

Spaceborne Bi- and Multistatic SAR: Potential and Challenges [PDF]

, 2006
Bi- and multistatic synthetic aperture radar (SAR) operates with distinct transmit and receive antennas that are mounted on separate platforms. Such a spatial separation has several operational advantages, which will increase the capability, reliability ...

Severe acute respiratory syndrome: ‘SARS’ or ‘not SARS’ [PDF]

Journal of Paediatrics and Child Health, 2004
Abstract:  Accurate clinical diagnosis of severe acute respiratory syndrome (SARS) based on the current World Health Organization definition is difficult and at times impossible at the early stage of the disease. Both false positive and false negative cases are commonly encountered and this could have far‐reaching detrimental effects on the patients ...

SARS in Pregnancy

AWHONN Lifelines, 2004
While severe acute respiratory syndrome (SARS) is increasing in prevalence throughout the world, there had not been a documented case of SARS in pregnancy until early 2003, when a pregnant woman infected with SARS sought care at this New Jersey Hospital in March 2003.

Prediction of implant failure risk due to periprosthetic femoral fracture after primary elective total hip arthroplasty: a simplified and validated model based on 154,519 total hip arthroplasties from the Swedish Arthroplasty Register

Bone & Joint Research
Aims: While cementless fixation offers potential advantages over cemented fixation, such as a shorter operating time, concerns linger over its higher cost and increased risk of periprosthetic fractures.

Detection of SARS Coronavirus in Patients with Suspected SARS [PDF]

Emerging Infectious Diseases, 2004
Cases of severe acute respiratory syndrome (SARS) were investigated for SARS coronavirus (SARS-CoV) through RNA tests, serologic response, and viral culture. Of 537 specimens from patients in whom SARS was clinically diagnosed, 332 (60%) had SARS-CoV RNA in one or more clinical specimens, compared with 1 (0.3%) of 332 samples from controls.

Flood Detection with SAR: A Review of Techniques and Datasets

Remote Sensing
Floods are among the most severe and impacting natural disasters. Their occurrence rate and intensity have been significantly increasing worldwide in the last years due to climate change and urbanization, bringing unprecedented effects on human lives and

Fractal Models for SAR images [PDF]

, 2011
In this thesis the modeling of SAR (Synthetic Aperture Radar) images of natural surfaces described via fractal models is dealt with. A complete theoretical forward model linking the parameters describing the scene observed by the sensor to the stochastic

Prediction of quality-of-life improvement after total hip arthroplasty: a simplified and internally validated model based on 82,526 total hip arthroplasties from the Swedish Arthroplasty Register

Bone & Joint Open
Aims: Pain and poor health-related quality of life measures serve as the primary indication for primary elective total hip arthroplasty (THA). It remains challenging to predict whether THA delivers the patient-anticipated improvements. Our study aimed to

A procedure to use GNSS data to calibrate satellite PSI data for the study of subsidence:an example from the north-western Adriatic coast (Italy)

European Journal of Remote Sensing, 2019
Multi-temporal interferometric Persistent Scatterers Interferometry (PSI) techniques derive from the elaboration of satellite Synthetic Aperture Radar (SAR) images and represent a useful tool to detect ground millimetric movements over wide areas; thanks
