A gold mining work force was followed prospectively over 1 yr for sputum nontuberculous mycobacterial (NTM) isolates. NTM were isolated from 118 men, of whom 32 (27%) met the American Thoracic Society (ATS) case-definitions for pulmonary NTM disease (23 M. kansasii, seven M. scrofulaceum, one M. avium, and one M. abscessus). Determining isolate significance(More)
UNLABELLED DESIGN AND OBJECTIVES: Potential risk factors for recurrence of tuberculosis (TB) were investigated in a retrospective cohort study of 305 human immunodeficiency virus (HIV) positive and 984 HIV-negative South African gold miners treated for TB with directly-observed, rifampicin-based regimens. Standard treatment changed from rifampicin,(More)
In this paper, we describe the development of an experimental testbed capable of producing controllable ocean-like flows in a laboratory setting. The objective is to develop a testbed to evaluate multi-robot strategies for tracking manifolds and La-grangian coherent structures (LCS) in the ocean. Recent theoretical results have shown that LCS coincide with(More)
— We address the synthesis of distributed control policies to enable a homogeneous team of mobile sensing agents to maintain a desired spatial distribution in a geophysical flow environment. Geophysical flows are natural large-scale fluidic environments such as oceans, eddies, jets, and rivers. In this work, we assume the agents have a " map " of the(More)
The main contribution of this paper is the experimental validation of a decentralized Receding Horizon Mixed Integer Nonlinear Programming (RH-MINLP) framework that can be used to solve the Multi-Vehicle Path Coordination (MVPC) problem. The MVPC problem features path-constrained vehicles that begin their transit from a fixed starting point and move towards(More)
