A number of studies investigated the impact of matrix metalloproteinase 2 (MMP2) expression on the survival of patients with osteosarcoma, but no consistent results were reported. To derive a more precise estimate of the prognostic role of MMP2 expression in patients with osteosarcoma, we systematically reviewed the published studies and carried out a(More)
Location data is one of the most widely used context data types in context-aware and ubiquitous computing applications. To support locating applications in indoor environments, numerous systems with different deployment costs and positioning accuracies have been developed over the past decade. One useful method, based on received signal strength (RSS),(More)
—In this paper, a novel forward-looking imaging method based on the compressed sensing is proposed for scanning phased array radar (PAR) in order to improve the azimuth resolution. Firstly, the echo of targets is modeled according to the principle of PAR. Then, it is analyzed why some of the former methods as multi-channel deconvolution are ineffective(More)
