The scs′ Boundary Element: Characterization of Boundary Element-Associated Factors
Boundary elements are thought to define the peripheries of chromatin domains and to restrict enhancer-promoter interactions to their target genes within their domains. We previously characterized a cDNA encoding the BEAF-32A protein (32A), which binds with high affinity to the scs' boundary element from the Drosophila melanogaster 87A7 hsp70 locus ...

Subregion Boundary Element Method
The system of equations for each subregion, which is derived from the boundary integral equation, is transformed to an equation similar to the stiffness equation of the finite element method. The global equation is made by the superposition of these matrix equations.

A FEM-Green Approach for Magnetic Field Problems with Open Boundaries
A new finite element method/boundary element method (FEM/BEM) scheme is proposed for the solution of the 2D magnetic static and quasi-static problems with unbounded domains. The novelty is an original approach in the treatment of the outer region.
