We have examined target detection performance in two monkey subjects during visual search with eye movements as a function of stimulus density and the eccentricity of the target from fixation. As expected, search time and the number of fixations per trial were related to the number of array objects in conjunction style arrays. High probability detection of targets occurs only within a restricte...
we report the growth and characterization of cu nanoparticles thin film of on glass substrate by pulse laser deposition method. the cu thin film prepared with different energy 50, 60, 70, and 80 mj. the energy effect on the morphological, structural and optical properties were studied by afm, xrd and uv-visible spectrophotometer. surface topography studied by atomic force microscopy revealed na...
The degree to which debris-covered glaciers record past environmental conditions is debated. Here we describe a novel palaeoclimate archive derived from the surface morphology and internal debris within cold-based debris-covered glaciers in Antarctica. Results show that subtle changes in mass balance impart major changes in the concentration of englacial debris and corresponding surface topogra...
OBJECTIVES This study sought to evaluate the structural integrity of balloon-expandable stents used in transcatheter aortic valve replacement. BACKGROUND Underexpansion, deformation, or fracture of stent frames may affect transcatheter heart valve (THV) function and durability. METHODS Patients >1 year after transcatheter aortic valve replacement underwent multidetector computed tomography....
