The paper is devoted to the eigenvalue problem for a second order strongly elliptic operator. The problem is considered on curved domains, which require interpolated boundary conditions in approximating finite element formulation. The necessary triangulations for solving the eigenvalue problem consists of isoparametric elements of degree n, where n is any integer greater than two. An approximat...

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....

The extreme eigenvalues of adjacency matrices are important indicators on the influence of topological structures to the collective dynamical behavior of complex networks. Recent findings on the ensemble averageability of the extreme eigenvalue have further authenticated its applicability to the study of network dynamics. However, the ensemble average of extreme eigenvalue has only been solved ...

According to metapopulation theory, the capacity of a habitat patch network to support the persistence of a species is measured by the metapopulation capacity of the patch network. Mathematically, metapopulation capacity is given by the leading eigenvalue kM of an appropriately constructed non-negative n n matrix M, where n is the number of habitat patches. Both habitat destruction (in the sens...

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...

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 ...
