Resolving Boundary Layers with Harmonic Extension Finite Elements

open access: yesMathematical and Computational Applications, 2022
In recent years, the standard numerical methods for partial differential equations have been extended with variants that address the issue of domain discretisation in complicated domains.

A single heterochromatin boundary element imposes position-independent antisilencing activity in Saccharomyces cerevisiae minichromosomes. [PDF]

open access: yesPLoS ONE, 2011
Chromatin boundary elements serve as cis-acting regulatory DNA signals required to protect genes from the effects of the neighboring heterochromatin. In the yeast genome, boundary elements act by establishing barriers for heterochromatin spreading and ...

Three-Dimensional Elastodynamic Analysis Employing Partially Discontinuous Boundary Elements

open access: yesAlgorithms, 2021
Compared with continuous elements, discontinuous elements advance in processing the discontinuity of physical variables at corner points and discretized models with complex boundaries.

The scs′ Boundary Element: Characterization of Boundary Element-Associated Factors

open access: yesMolecular and Cellular Biology, 1997
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 ...

Defect Detection in Plate Structures using Wavelet Transformation

open access: yesEngineering Transactions, 2016
This paper is concerned with defect detection in plate structures while considering the influence of external loads. The examined structures are based on Kirchhoff plate structures. Rectangular plate structures are considered.

Non-linear analysis of reinforced concrete plates by the boundary element method and continuum damage mechanics - DOI: 10.4025/actascitechnol.v31i1.348

open access: yesActa Scientiarum: Technology, 2009
In this work, non-linear analyses of reinforced concrete plates are performed by using a BEM formulation, based on Kirchhoff’s theory, which has already proved to be a robust technique to deal with plate problems.

Crouzeix–Raviart boundary elements

open access: yesNumerische Mathematik, 2009
The authors analyze a non-conforming boundary element method with discontinuous elements. More precisely, the use of piecewise linear Crouzeix-Raviart elements where jumps of basis functions across element boundaries have integral mean zero is studied. The meshes are triangular and regular, but the basis functions are not continuous.
