This paper introduces into seven real-world road driving stereo sequences (provided by Daimler AG, Germany; now freely available for academic research); it also informs about their use for performance evaluation in some experiments using common stereo and motion analysis algorithms. Often, such algorithms are tested on a few frames only, or on synthetic(More)
BACKGROUND Heat stress can be acutely cytotoxic, and heat stress-induced apoptosis is a prominent pathological feature of heat-related illnesses, although the precise mechanisms by which heat stress triggers apoptosis are poorly defined. METHODS The percentages of viability and cell death were assessed by WST-1 and LDH release assays. Apoptosis was(More)
Urbanization has transformed the world’s landscapes, resulting in a series of ecological and environmental problems. To assess urbanization impacts and improve sustainability, one of the first questions that we must address is: how much of the world’s land has been urbanized? Unfortunately, the estimates of the global urban land reported in the literature(More)
Around the globe, manufacturers are increasingly trying to design products that are as ecological as possible, which is leading to the establishment of new design methods focused on environmentally conscious design (ECD). Materials selection, as a key element in ECD, differs from traditional design by introducing three additional requirements: life cycle(More)
Diabetes Mellitus (DM)-induced bladder dysfunction is predominantly due to the long-term oxidative stress caused by hyperglycemia. Grape seed proanthocyanidin extract (GSPE) has been reported to possess a broad spectrum of pharmacological and therapeutic properties against oxidative stress. However, its protective effects against diabetic bladder(More)
