BACKGROUND Patency of failed axillofemoral (ax-fem) grafts following thrombectomy is so poor, aortofemoral grafts are recommended as treatment for ax-fem graft thrombosis. In patients who are not candidates for aortic grafting, repeat ax-fem grafting is an alternative to thrombectomy. This report compares our experience treating ax-fem graft thrombosis with replacement or revision vs thrombecto...

Title of Dissertation CHARACTERIZATION OF THE ROLE OF THE FEM GENES IN THE SEX DETERMINATION PATHWAY OF CAENORHABDITIS BRIGGSAE Robin Cook Hill, Doctor of Philosophy, 2008 Directed by: Professor Eric Haag Department of Biology In the genus Caenorhabditis, self-fertile hermaphrodites in C.elegans and C.briggsae evolved from females by developing the ability to generate a limited number of self s...

Somatic sex determination in Caenorhabditis elegans involves a signal transduction pathway linking a membrane receptor to a transcription factor. The fem-2 gene is central to this pathway, producing a protein phosphatase (FEM-2) of the type 2C (PP2C). FEM-2 contains a long amino terminus that is absent in canonical PP2C enzymes. The function of this domain is difficult to predict, since it show...

This paper investigates recent progress on a-posteriori error analysis for the high-order finite element method(FEM). The paper will discuss the differences between a-posteriori error estimations for lower-order FEM and those for high-order FEM, and analyzes the technical and methodological differences on a-posteriori error estimations for high-order FEM in one dimension and in high dimensions....

The most remarkable outcome of a gene duplication event is the evolution of a novel function. Little information exists on how the rise of a novel function affects the evolution of its paralogous sister gene copy, however. We studied the evolution of the feminizer (fem) gene from which the gene complementary sex determiner (csd) recently derived by tandem duplication within the honey bee (Apis)...

In this study, a cellular automaton (CA) is developed o combine the advantages of finite element method (FEM) and meshless method to analyze two-dimensional elastic problems. By the CA, a two-dimensional domain is discretized into a grid of nodes which are distributed randomly in the domain. For convenience, the nodes are classified into the FEM group and the meshless group. In the FEM zone tha...

This paper compares the hybrid FEM-BEM and FEM-DBCI methods for the solution of openboundary electrostatic field problems. Both methods couple a differential equation for the interior problem with an integral equation for the exterior one. The comparison shows that FEM-BEM is more accurate than FEM-DBCI but requires more computing time. PACS. 41.20.Cv Electrostatics; Poisson and Laplace equatio...

The fem-3 gene is required for specification of the male fate in the nematode Caenorhabditis elegans: XO males need fem-3 for male differentiation in both soma and germ line; XX hermaphrodites need it for the production of sperm. We have cloned fem-3 by transposon tagging. Among eight spontaneous fem-3 mutations generated in a strain in which the transposable element Tc1 is mobile, six contain ...

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 field continuity on the boundary that separates the FEM and MoM regions. Hierarchical higher-order tangential vector finite elements (TVFE’s) are of practical interest because they can be easily combined with low-ord...
