— This paper presents a novel wideband sweep non-linearity software correction method for a frequency modulated continuous wave (FMCW) transceiver based on the high-order ambiguity function (HAF) and time resampling. By emphasizing the polynomial-phase nature of the FMCW signal, it is shown that the HAF processing algorithm is well suited for estimating the(More)

— Infrastructure monitoring applications can require the tracking of slowly moving points of a certain structure. Given a certain point from a structure to be monitored, in the context of available SAR products where the image is already focused in a slant range-azimuth grid, it is not obvious if this point is the scattering center, if it is in layover or(More)
A frequency modulated continuous wave (FMCW) X-band radar platform for millimetric displacements measurement of short-range targets is presented in this paper. The platform's transceiver is based on a heterodyne architecture because the beat frequency is relatively small for short-range targets and it can be placed in the frequency range influenced by the(More)
UNLABELLED The present clinical trial analyzed the safety of gene therapy using plasmidial constructs expressing vascular endothelial and hepatocyte growth factors in patients with critical limb ischemia. The study included 43 patients: 29 in the treatment group and 14 allocated to the placebo group. The primary end points were the rate of major amputations(More)

PURPOSE In aged humans, stroke is a major cause of disability for which no neuroprotective measures are available. In animal studies of focal ischemia, short-term hypothermia often reduces infarct size. Nevertheless, efficient neuroprotection requires long-term, regulated lowering of whole body temperature. Previously, we reported that post-stroke exposure(More)
