Agua de Dios was a leprosarium for leprosy patients' obligatory isolation (1872-1961). Its leprosy incidence is the highest in Colombia (1.5-7/10000). Relapses are common. Government grant of US$ 200 per month subsidy is available to patients with disabilities. Spontaneous consultation with neural symptoms is frequent and simulation to get the subsidy has(More)
In advance of an updated monographic revision of Swartzia (Leguminosae), we discuss the taxonomy of the genus in extra-Amazonian Brazil and present descriptions of five new species. All of the new species are narrowly distributed in eastern Brazil in threatened Atlantic wet forest and coastal scrub habitats. Four of them—S. alagoensis, S. arenophila, S.(More)
OBJECTIVE Actively searching for leprosy, other skin diseases and BCG vaccination scars amongst school children from Agua de Dios, the municipality having the highest prevalence of leprosy in Colombia. METHODS A clinical examination of the children was carried out by nurses, interns, general practitioners and experts on leprosy. Skin smear tests and skin(More)
Compressed sensing has proved key in resolving commonly sparse scenarios where MIMO Radar schemes are envisioned. This is normally addressed via cross-range imaging, equipped with a matched filter for each desired range. This paper takes a more general approach by formulating a full 3D convolution sensing matrix for joint range/cross-range imaging, while(More)
Leprosy relapses are mainly due to bacillary persistence and diamino-diphenyl-sulphone (DDS) monotherapy. Case histories were examined for 33 patients with lepromatous leprosy (LL), diagnosed 7-48 years before the relapse and treated only with DDS during 4 to 38 years. Twenty-eight patients received irregular non-supervised polychemotherapy (PCT) since(More)

In MIMO Radar schemes, sparse scenarios have been successfully exploited by compressed sensing (CS) techniques. We address the ill-conditioning inherent to the linear model of a 3D Radar imaging system, by proposing a two-step decoupling procedure which induces structure, and allows for fast matrix products to efficiently recover the target image. This is(More)
