Background: Periprosthetic hip infections (PHIs) are troublesome complications of hip arthroplasties. The gold standard procedure for treating chronic PHI is a 2-stage approach. Recently, however, more conservative approaches have been developed to spare the osseointegrated components and avoid sequestra, bone loss, devascularization, and difficult reconstructions. The partial ...

This paper shows the application of a functional version of principal component analysis to build a parametrization of vocal tract area functions for vowel production. Sets of measured area values for ten vowels are expressed as smooth functional data and next decomposed into a mean area function and a basis of orthogonal eigenfunctions. Interpretations of the first four eigenfunctions are prov...

In this paper twelve different empirical resistance coefficients expressed in terms of Manning's roughness are used apiece in seventeen known compositing methods. The data obtained from ten different cross-sections of the Sefidrood River, Iran, are used for the evaluation of the empiricalformulas. The present case-study is selected from a reach with gravel bed topology. Then no remarkable bed f...

background and objectives: evaluating the performance of clinical units is critical for effective managementof health settings. certain assessment of clinical variables for performance analysis is not always possible,calling for use of uncertainty theory. this study aimed to develop and evaluate an integrated independentcomponent analysis-fuzzy-data envelopment analysis approach to accurate the...

This paper outlines and analyses the behaviours of small and medium enterprises with respect to the evaluation of electronic commerce investments, and the subsequent realisation of the anticipated benefits from those investments. The responses of executives who participated in the study suggested that on-going involvement in electronic commerce did not come cheaply. Nonetheless, our study sugge...

In recent times, games-based learning has been attracting the attention of educators around the world. One of the challenges in deploying games-based learning to cover a larger proportion of the curriculum is the high costs associated with development of the games. Games development often requires specialized skills sets. Inputs from academic specialists for the learning content and pedagogy is...

Peter Reddien attended graduate school at MIT in the lab of Bob Horvitz, studying programmed cell death in Caenorhabditis elegans. He carried out postdoctoral work with Alejandro Sánchez Alvarado at the University of Utah, where he performed the fi rst planarian RNA interference screen. He started his lab at the Whitehead Institute and the Department of Biology at MIT in 2005 and is an HHMI Inv...
