The sentinel node evaluation has revolutionized the modern surgical management of cutaneous melanoma and breast cancer. In gynecologic oncology, sentinel node mapping has been mainly studied in vulvar and cervical cancer. In vulvar cancer, data from 12 studies including 353 cases indicate that the sentinel node detection rate is 92% and the negative-predictive value is 99%. Three groin recurren...

In this paper we explore the performances and the opportunities provided by the European satellite Sentinel-1 for water resource management applications in low-income countries. The analysis is supported by a synthetic aperture radar (SAR) simulator, which allowed the quantification of the expected characteristics of Sentinel-1 products in three applications: interferometric digital elevation m...

The European Space Agency is currently developing Sentinel-1, a constellation of two polar-orbiting C-band radar satellites for operational Synthetic Aperture Radar (SAR) applications. The Sentinel-1 mission is designed for continuous and operational monitoring. The goal is to map the European land mass once every four days in Interferometric Wide Swath (IWS) mode, and the global land surface a...

The rich, complementary data provided by Sentinel-1 and Sentinel-2 satellite constellations host considerable potential to transform Earth observation (EO) applications. However, a substantial amount of effort infrastructure is still required for the generation analysis-ready (ARD) from low-level products European Space Agency (ESA). Here, flexible Python framework able generate range consisten...

Asia dominates the world’s aquaculture sector, generating almost 90 percent of its total annual global production. Fish, shrimp, and mollusks are mainly farmed in land-based pond systems serve as a primary protein source for millions people. The production area occupied has expanded rapidly coastal regions since early 1990s. growth was boosted by an increasing demand fish seafood from growing w...

In this study, we present an operational methodology for mapping irrigated areas at plot scale, which overcomes the limitation of terrain data availability, using Sentinel-1 (S1) C-band SAR (synthetic-aperture radar) and Sentinel-2 (S2) optical time series. The method was performed over a study site located near Orléans city north-central France four years (2017 until 2020). First, training non...
