Semi-Implicit Finite Element Method and its Convergence of Single-Particle Reconstruction Using L2-Gradient Flow
Semi-Implicit Finite Element Method Convergence Single-Particle Reconstruction
2012/8/10
In an earlier paper, we presented an iterative algorithm for reconstructing a three dimensional
density function from a set of two dimensional electron microscopy images. By
minimizing an energy fun...

In this paper, we present a novel L2-gradient flow based semi-implicit finite element
method for solving a variational model of image reconstruction under various data scenarios,
especially for the ...
Hyperbolic Gradient Flow: Evolution of Graphs in R^{n+1}
Hyperbolic gradient flow geometry of manifold global existence smooth solution shock wave.

We describe a gradient flow structure for the inviscid Langmuir layer Stokesian subfluid model introduced recently by Alexander et al [1].
In this paper we introduce a new geometric ow | the hyperbolic gradient ow for graphs in the (n + 1)-dimensional Euclidean space Rn+1.
