STUDY OBJECTIVES There have been no health-care cost evaluations comparing the use of low-molecular-weight heparin (LMWH) to unfractionated heparin (UH) as "bridge therapy" in the perioperative period in patients receiving long-term oral anticoagulant (OAC) therapy who need interruption of therapy to undergo an elective surgical procedure. We performed a retrospective analysis of the medical an...

We study the gradient superconvergence of bilinear finite volume element (FVE) solving the elliptic problems. First, a superclose weak estimate is established for the bilinear form of the FVE method. Then, we prove that the gradient approximation of the FVE solution has the superconvergence property: max P∈S |(∇u−∇uh)(P)| = O(h2)| lnh|, where ∇uh(P) denotes the average gradient on elements cont...

Let Ph be a self-adjoint semiclassical pseudodifferential operator on a manifold M such that the bicharacteristic flow of the principal symbol on T ∗M is completely integrable and the subprincipal symbol of Ph vanishes. Consider a semiclassical family of eigenfunctions, or, more generally, quasimodes uh of Ph. We show that on a nondegenerate rational invariant torus, Lagrangian regularity of uh...

Spontaneous speech differs in several ways from the sentences often studied in psycholinguistics experiments. One important difference is that naturally produced utterances often contain disfluencies. In this study, we examined how the presence of ‘‘uh’’ in a spoken sentence might affect processes that assign syntactic structure (i.e., parsing). Four experiments are reported. In the first, part...

In this study, we investigate the use of filler particles (FPs) uh, um, hm, as well glottal FPs and tongue clicks 100 male native German speakers in a corpus spontaneous speech. For purpose, frequency distribution, FP duration, duration pauses surrounding FPs, voice quality their vowel are investigated two conditions, namely, normal speech Lombard Speaker-specific patterns on basis twelve sampl...

This paper is concerned with a priori error estimates for the piecewise linear nite element approximation of the classical obstacle problem. We demonstrate by means of two onedimensional counterexamples that the L2-error between the exact solution u and the nite element approximation uh is typically not of order two even if the exact solution is in H 2(Ω) and an estimate of the form ‖u − uh‖H1 ...

This paper provides an error analysis for the Crank–Nicolson extrapolation scheme of time discretization applied to the spatially discrete stabilized finite element approximation of the two-dimensional time-dependent Navier–Stokes problem, where the finite element space pair (Xh,Mh) for the approximation (uh, p n h) of the velocity u and the pressure p is constructed by the low-order finite ele...

Little research has been done to explore differences in the use of the fillers ‘um’ and ‘uh’ between children with Autistic Spectrum Disorder (ASD) and those with typical development (TD). Quantifying any differences could aid in diagnosing ASD, understanding its nature, and better understanding the mechanisms involved in dialogue processing. In this paper, we report on a study of dialogues bet...

A bottom tangle is a tangle in a cube consisting of arc components whose boundary points are on a line in the bottom square of the cube. A ribbon bottom tangle is a bottom tangle whose closure is a ribbon link. For every n-component ribbon bottom tangle T , we prove that the universal invariant JT of T associated to the quantized enveloping algebra Uh(sl2) of the Lie algebra sl2 is contained in...

One of the most important tools for accelerating comprehensive computations in multi dimensions (in particular in 3-D) is the local adaption of the grid. In order to minimize the computing time the local grid size should be chosen such that the error ||u − uh|| between the exact solution u and the numerical solution uh is less than a given tolerance and such that the total number of cells is as...
