Gecko toe pads show strong adhesion on various surfaces yet remain remarkably clean around everyday contaminants. An understanding of how geckos clean their toe pads while being in motion is essential for the elucidation of animal behaviours as well as the design of biomimetic devices with optimal performance. Here, we test the self-cleaning of geckos(More)
Gecko adhesion is expected to be temperature insensitive over the range of temperatures typically experienced by geckos. Previous work is limited and equivocal on whether this expectation holds. We tested the temperature dependence of adhesion in Tokay and Day geckos and found that clinging ability at 12 degrees C was nearly double the clinging ability at(More)
UNLABELLED Surfactant therapy has become an effective standard therapy for infants with respiratory distress syndrome (RDS). The first dose may be given either as prophylaxis immediately after delivery, or as rescue after an infant has developed RDS. Second and subsequent doses are currently recommended by the manufacturers to be administered at minimal(More)
With the maturity of machine learning methods to provide satisfying Content-Based Image Retrieval systems (CBIR), research focus has recently turned back towards visual saliency analysis. The goal in these works is to extract even more efficient visual features than the existing ones. However, analyzing visual saliency is critically dependent on the task to(More)
A semiconductor wafer fab requires a significant amount of energy to maintain its daily operations. Solar photovoltaics (PV) is a clean and renewable technology that can be potentially used to power large wafer fabs. There exist some critical factors slowing the proliferation of facilities powered by PVs, including high capital costs and power output(More)
Retrieving specific categories of images among billions of images usually requires an annotation step. Unfortunately, keywords-based techniques suffer from the semantic gap existing between a semantic concept and its digital representation. Content Based Image Retrieval (CBIR) systems tackle this issue simply considering semantic proximities can be mapped(More)
This study examined the effect of overt head movement on attitudes toward a product. In a headphones test, participants were required to listen to music and to either nod or shake their heads. Some participants listened to a CD of music; other participants listened to a CD of the same music and a persuasive message about the headphones. Overt head movement(More)
PURPOSE/OBJECTIVES The aim of this study is to analyze the results of exclusive interstitial brachytherapy (IBT) as a conservative approach in the treatment of penile cancer confined to the glans or the shaft with long-term follow-up in a single institution. MATERIALS/METHODS Between July 1992 and November 2013, 73 consecutive patients with non-metastatic(More)
