Dendritic spines are the postsynaptic sites that receive most of the excitatory synaptic inputs, and thus provide the structural basis for synaptic function. Here, we describe an accurate method for measurement and analysis of spine morphology based on structured illumination microscopy (SIM) and comp...
The weak formulation in (2) and (3) imposes the Dirichlet conditions by the penalty method, which bypasses the computation of local stabilization parameters. The analysis of the conditioning of immersed finite elements in [35] conveys that cut-element-specific conditioning problems are not essentiall...

powerful collection of high-performance software libraries. These libraries provide many operating system-type services, such as memory andthread managementand interthread communication andsynchronization, as well as development utilities, such as geometry, container, scene-graph, and persistent I/O ...
this can change the model and introduce error to the original solution.It is well known from numerical analysis that ill-conditioned matrices cannot be accurately inverted.In this paper, we develop a multilevel computational method that scales well with the number of observations and dimensions. A...
The authors propose a two-level ILU preconditioner for the preconditioned GMRES method. The computation and application of the preconditioner is based on graph partitioning techniques. An important part of this special issue is devoted to analyze problems related to random differential equations and ...
The DT method delineates the pore space into a space-filling set of tetrahedral-shaped cells, where the vertices of the tetrahedra are the particle centroids. An example is shown in Fig. 1a. Each tetrahedron represents a single pore in the network model, and faces of tetrahedra are the ...
adoptions have to be done to cope with numerical variables as well as probabilistic patterns. This problem also exists in structured representations such as semantic networks. Besides, logic based representations are considered less comprehensible and harder to visualize than other graph based representatio...
