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...

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....

OBJECTIVE Covert visual spatial attention is a relatively new task used in brain computer interfaces (BCIs) and little is known about the characteristics which may affect performance in BCI tasks. We investigated whether eccentricity and task difficulty affect alpha lateralization and BCI performance. APPROACH We conducted a magnetoencephalography study with 14 participants who performed a co...

Let G be a simple connected graph and {v_1,v_2,..., v_k} be the set of pendent (vertices of degree one) vertices of G. The reduced distance matrix of G is a square matrix whose (i,j)-entry is the topological distance between v_i and v_j of G. In this paper, we compute the spectrum of the reduced distance matrix of the generalized Bethe trees.

Due to the use of deicing salt, marine and offshore environments may cause rebar corrosion in RC flat-slab floor systems. This increases possibility punching shear failure slab–column connections. However, few research results are available for connections with corroded under eccentric load, which is very common realistic loading conditions. To fill this gap, 15 full-scale flat were fabricated ...

We study the Steiner k-eccentricity on trees, which generalizes previous one in paper [On average 3-eccentricity of arXiv:2005.10319]. achieve much stronger properties for k-ecc tree than that paper. Based this, a linear time algorithm is devised to calculate vertex tree. On other hand, lower and upper bounds index order n are established based novel technique quite different also easier follow...
