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...

In this paper, we present a time integration scheme applied to the Discontinuous Galerkin finite element method (DG-FEM, [1]) for the computation of electromagnetic fields in the interior of three-dimensional structures. This approach is also known as Arbitrary High-Order Derivative Discontinuous Galerkin (ADER-DG, [2, 3]). By this method, we reach arbitrary high accuracy not only in space but ...

Many applications in biomedical engineering and surgical simulators require effective modeling methods for dynamic interactive simulations. Due to its high computation time, the standard Finite Element Method (FEM) cannot be used in such cases. A FEM-based method is first presented, which rely on the decomposition of the deformation of each element into a rigid motion and a pure deformation, an...

The goal of this study was to determine the effect of acute transdermal 17β-oestradiol (E2 ) on the adipogenic potential of subcutaneous adipose-derived stem cells (ASC) in post-menopausal women. Post-menopausal women (n = 11; mean age 57 ± 4.5 years) were treated for 2 weeks, in a randomized, cross-over design, with transdermal E2 (0.15 mg) or placebo patches. Biopsies of abdominal (AB) and fe...

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...

intraperitoneal (ip) injection of bupropion (3,6, amine (4,16 mg kg•&apos;) induced dose-dependent climbing in mice. the climbing response induced by both drugs were decreased in animals pretreated either with the 0-1 antagonist sch 233<)0 or the 0-2 antagonist sulpiride. the α-adrenoceptor blocker phenoxybenzamine decreased the climbing induced by both bupropion and amphetamine, but the β-adre...

SIS100: For SIS100 modified versions of the fast-ramped superferric magnets of the Nuclotron synchrotron at JINR Dubna will be used. The original Nuclotron dipole magnets produce an overall AC loss at 4 K of about 38 W/m (standard cycle: Bmax=2 T, dB/dt = 4 T/s, repetition rate of 1 Hz). It is necessary to reduce the loss at cryogenic temperatures at least by a factor of 2, the corresponding R&...

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...
