BACKGROUND Whether bipolar hemiarthroplasty (BH) for displaced femoral neck fractures has benefit over unipolar hemiarthroplasty (UH) remains controversial. We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to evaluate the relative effects between BH and UH. METHODS A systematic literature search (up to April, 2014) was conducted to include RCTs compari...

Spoken language is full of disfluencies. A frequent sound expressing hesitation is uh (or any variant thereof), but its linguistic status is debated. This article offers a new perspective on hesitation particles. First, the position is defended that they are linguistic signals, hence words, and it is shown that they belong to the larger class of interjections on the basis of a number of qualita...

Tensor products of irreducible representations of the Jordanian quantum algebras Uh(sl(2)) and Uh(su(1, 1)) are considered. For both the highest weight finite dimensional representations of Uh(sl(2)) and lowest weight infinite dimensional ones of Uh(su(1, 1)) , it is shown that tensor product representations are reducible and that the decomposition rules to irreducible representations are exact...

Representation theory for the Jordanian quantum algebra Uh(sl(2)) is developed using a nonlinear relation between its generators and those of sl(2). Closed form expressions are given for the action of the generators of Uh(sl(2)) on the basis vectors of finite dimensional irreducible representations. In the tensor product of two such representations, a new basis is constructed on which the gener...

OBJECTIVES Our aim was to improve the prediction of unfavorable histopathology (UH) in neuroblastic tumors through combined imaging and biochemical parameters. METHODS 123I-MIBG SPECT and MRI was performed before surgical resection or biopsy in 47 consecutive pediatric patients with neuroblastic tumor. Semi-quantitative tumor-to-liver count-rate ratio (TLCRR), MRI tumor size and margins, urin...

BACKGROUND AND OBJECTIVE Either low molecular weight heparin (LMWH) or unfractionated heparin (UH) may be used for the prophylaxis of post-operative venous thromboembolic disease (VTD) in elective hip replacement. This study was aimed at assessing the cost-effectiveness of LMWH over UH from the society perspective, which considers all the outcomes occurring in the life-long time horizon. DESI...

Given a sequence of Galerkin spaces Xh of curl conforming vector fields, we state necessary and sufficient conditions under which it is true that the scalar product uh ·uh of two sequences of vector fields uh, uh ∈ Xh converging weakly in L, converges in the sense of distributions to the right limit, whenever uh is discrete divergence free and curluh is precompact in H−1. The conditions on Xh a...

By solving a set of recursion relations for the matrix elements of the Uh(sl(2)) generators, the finite dimensional highest weight representations of the algebra were obtained as factor representations. Taking a nonlinear combination of the generators of the two copies of the Uh(sl(2)) algebra, we obtained Uh(so(4)) algebra. The latter, on contraction, yields Uh(e(3)) algebra. A nonlinear map o...

While the so-called “fillers” um and uh share a great deal in the way of interpretation, association, and usage, they are far from perfect substitutes. Previous corpus research, focusing primarily on British English, has identified a number of social and discursive factors with which filler usage can vary, including pause length and position in an utterance and speaker age, gender, and social c...
