Elliptic homogenization problems in a domain Ω R d with n + 1 separate scales are reduced to elliptic problems in dimension (n + 1)d. These one-scale problems are discretized by a sparse tensor product finite element method (FEM). We prove that this sparse FEM has accuracy, work, and memory requirements comparable to those in a standard FEM for singlescale problems in Ω, while it gives numerica...

LA-related protein 1 (LARP-1) belongs to an RNA-binding protein family containing a LA motif. Here, we identify LARP-1 as a regulator of sex determination. In C. elegans hermaphrodites, a complex regulatory network regulates the switch from sperm to oocyte production. We find that simultaneous depletion of larp-1 and the Nanos homologue nos-3 results in germline masculinization. This phenotype ...

An algorithm for non-intrusively coupling a commercial finite element software with a research code implementing a hierarchical enrichment of finite element spaces is presented. Examples of hierarchical methods supported by the algorithm are the Generalized or eXtended FEM (GFEM), the scale-bridging GFEM with numerically defined enrichment functions (GFEMgl), and the p-version of the FEM. The p...

We extend the well-known form closure framework for rigid parts to holding a class of deformable parts. We consider 2D deformable parts modeled as polygons with a triangular FEM mesh and given stiffness matrix that models linear elasticity and the potential energy associated with deformations of the mesh. We define the D-space (deformation-space) of a part E as the C-space of all nodes in the F...

Caenorhabditis elegans and Caenorhabditis briggsae are both self-fertile hermaphroditic nematodes that evolved independently from male/female ancestors. In C. elegans, FEM-1, FEM-2, and FEM-3 specify male fates by promoting proteolysis of the male-repressing transcription factor, TRA-1. Phenotypes of tra-1 and fem mutants are consistent with this simple linear model in the soma, but not in the ...

Detailed Finite Element Method (FEM) based simulations for 2G HTS tapes return high quality results, but the computation takes a long time due to non-linearity of superconducting properties and they needed mesh density. This work describes method prediction quench behavior in tape on series 2D FEM model short length many different conditions. The random forest is trained by set results from sho...

Pipelines used in the petrochemical industries are an essential means of transporting materials economically, efficiently and safely. However, ferromagnetism can lead to cracking, corrosion and other defects due to operation, wear, stress and accidental damage. Moreover, because the pipelines work under the condition of high pressure and for long periods of time, if these defects cannot be disc...

Hybrid FEM/MoM methods combine the finite element method (FEM) and the method of moments (MoM) to model inhomogeneous unbounded problems. These two methods are coupled by enforcing the continuity of tangential fields on the boundary that separates the FEM and MoM regions. When modeling complex geometries with many elements on the boundary, the MoM part of the problem is the bottleneck of the hy...
