The Functional Outcome of Hip Resurfacing and Large-head THA Is the Same A Randomized, Double-blind Study

Better functional outcome is believed by some to occur after hip resurfacing (HR) than conventional 28- mm total hip arthroplasty (THA) in young and active patients with hip osteoarthritis. However, the postulated superior outcome of HR over THA may simply be the result of a bias in patient selection or the use of a larger femoral head. We therefore asked whether HR would demonstrate superior functional outcome when compared with a THA with a large-diameter femoral head in a ran- domized, double-blind study. Gait speed and postural balance evaluations, functional tests, and clinical data were analyzed preoperatively and at 3, 6, and 12 months after surgery. Gait speed was used as the primary outcome measure. Forty-eight patients were randomized in the study and a third group of 14 healthy subjects served as controls. The gait speed and postural balance evaluations, the per- formance at most functional tests, and clinical scores were similar in HR and large-head THA groups at each followup period. The operated patients reached most control group values at 3 months postoperatively. By these measures, HR did not provide better clinical function over large-head THA.
The Study of Metalanguage in Foreign Language Teaching

Metalanguage is the specialized language used to describing and interpreting language, which is a "tool language". This paper discusses from the aspects of metalanguage application in foreign language teaching and the training of students' metalanguage consciousness and ability. It is pointed out that metalanguage is an effective tool in foreign language teaching. For foreign language learners, the use of metalanguage in foreign language teaching can not only cultivate and improve the ability to use language, but also can improve the ability to describe and explain the language with metalanguage.
kNNSumm: um sumarizador automático de documentos utilizando aprendizado baseado em instâncias

In this work is presented the architecture of kNNSumm (k-NN Summarizer), an automatic document summarizer based on a instance based machine learning approach. The results achieved by its use on a document collection of english documents extracted from the TIPSTER base which is widely used in the literature are presented also. Additionally, we present a simple and didactic example of the procedures used by the summarizer, and in a more general way the text summarization task with machine learning.

The line of argument in Chopin's E minor Prelude

SCHOLARS in recent years have increasingly turned to musical recordings as a resource for studying performance practices. This article adds to the momentum by undertaking a comparative survey of 14 recordings of Chopin's Prelude in E minor, op.28 no.4. Its primary purpose, however, is not to gauge fidelity to an ostensibly original performance aesthetic' or to trace an evolution in the performance styles of the individual performers-the goals of many comparative investigations-but to identify the ways in which these pianists meet the expressive and technical challenges inherent in the score and overcome the various conceptual problems that surround the performance of any work by Chopin. In particular, I shall try to discover the unique logic, or line of argument, that lies at the heart of each interpretation. I shall also assess the role of historical evidence (among other things) in shaping a given performance, all the while claiming that what generally determines the latter's success is not its scholarly probity but the extent to which it coheres and is coherent, and the extent to which it convinces, or moves, the listener. That contention is the basis on which the 14 recordings are evaluated in the second part of the article.
Palliative Orthopaedic Surgery

Metastases to bone are the most common cause of destructive lesions to the skeleton in adults. Primary goals in the palliative management of metastatic bone lesions include controlling pain, preserving function, and helping to maintain or improve quality of life. These goals may be accomplished through various non operative and operative means. While some patients may not need surgical fixation of pathologic fractures or impending fractures, many will require durable bone fixation or replacement. Thoughtful evaluation of these patients by orthopaedic surgeons in collaboration with other members of the oncology team will help optimize treatment. *Corresponding author: Todd E Bertrand, Department of Orthopaedic Surgery,Duke University School of Medicine, DUMC Box 3000, Durham, NC 27710, USA, Tel: 919684-3170; Fax: 919-681-7672; E-mail: todd.bertrand@dm.duke. edu Received January 10, 2013; Accepted February 11, 2013; Published February 14, 2013 Citation: Bertrand TE, Brigman BE (2013) Palliative Orthopaedic Surgery.

Parsing the parser: A case study in programming style

The value of the computational approach in the cognitive sciences lays both in the need to formalize theories such that they can be implemented as computer programs and in the subsequent ease of experimenting with these programs. In this paper I hope to show that, the cleaner a programming style is used, the more these benefits will be present. As an example, the musical parser designed and described by Longuet-Higgins is re-implemented in a clean functional programming style in LISP. This yields a, so called, micro version that makes the theoretical issues that the original program was supposed to illustrate, stand out much more clearly.
HeyMoe: Leveraging virtual robot and game mechanics in mobile prototype application design for Chinese language learning

With the growth of internet technology, individuals currently have a better experience in using interactive systems like desktop computer software or mobile device applications than ever before. Moreover, using mobile phones in learning activities is becoming increasingly popular. However, the learning applications today do not fully meet the learner’s needs, especially for young adults who have some interest but lack fundamental knowledge in their study subjects. Combining mobile phone technology and game elements could make it possible to solve this problem. In this way, the limitations of location and the sometimes boring nature of the learning activities could be efficiently reduced. This study presents an idea of applying virtual robot and game elements to language learning activities and creating a mobile device application prototype to enhance the learner’s Chinese study experience.
"I See England, I See France…": Robert Kroetsch's Alibi

For Robert Kroetsch the play of language and consummation, word and world, is an intricate one, a Derridean replication of substitutions that always ensnares man in alibis. There is a perpetual deferring of what a character wants by its alibi; everything is exposed as a sign of something else. This is symbolised principally by the recurring motif of panties, which provide, at best, a false succor for unrealized desire. The problem in the larger sense is that of identity as well as of identifying. A similar theme is present in Kroetsch's Gone Indian. Characters wish to unlock the secrets of language but are stymied by transposed signifiers.
STUDY OF SOCIAL IMAGE RE-RANKING ACCORDING INTER AND INTRA USER IMPACT

Social media provides most of the websites for example Facebook that allows users to describe their images with special tag. That helps in the web image retrival system tag based image search is very important method to find out images uploaded by the social users in most of social websites that helps to make the result releated and improve the variety of the images. we considered the visual information and click count of the images in this system first we sort the images by inter-user ranking the user who upload the maximum image will rank higher. After this we implement intra-user ranking on the ranked user image set and only the most related image from each user image database is selected. These selected images combine the final retrived results. We build an inverted index for social image databases to improve the speed of searching of an images.
LMS-02: A phase II single-arm multicenter study of doxorubicin in combination with trabectedin as a first-line treatment of advanced uterine leiomyosarcoma (u-LMS) and soft tissue LMS (ST-LMS): First results in patients with u-LMS.

10505 Background: U-LMS and ST-LMS are rare tumours with poor prognosis when metastatic or locally advanced, presenting moderate chemosensitivity mainly to doxorubicine (doxo), ifosfamide (ifo), cisplatin, gemcitabine (gem) and trabectidine (trab). Response rates (RR) in combination therapies (1stline) does not exceed 50% for U-LMS and 35% for ST-LMS. The most active ones are doxo combinations (most of the time with ifo or dacarbazine) and gem + docetaxel (in particular in U-LMS) with a mean response durations of 3 to 6 months. Trab was demonstrated a definite activity on pre-treated LMS (RR of approximately 20% in LMS overall [U-LMS in particular]). In view of these encouraging results on LMS, a study combining trab with doxo as first line therapy for LMS is of interest. Methods: Patients (pts) received every 3 weeks, 6 cycles of doxo 60 mg/m2 followed by trab 1.1 mg/m23-h at day 1, and pegfilgrastim 6 mg on Day 2. Study primary objective: to determine the disease control rate (DCR) (ORR+SD). Secondary o.
TECHNOLOGY ENHANCED FEEDBACK ON ASSESSMENT

The two most common forms of providing assessment feedback to students have been written comments on the assignment or face to face discussions. However research reveals that written comments are often limited in depth and marred by ambiguity while face to face discussions are often impractical and dependent on student memory. In contrast over recent years we have witnessed an increase in technology enhanced modes of feedback delivery. At its simplest this involves annotating documents with written comments. However, there are a variety of other options. This paper will outline the limited but growing empirical research on the design and impact of video, audio, screencast and other annotation feedback mechanisms. Drawing on this literature and the presenters' own research we propose a series of design principles for the creation of effective technology enhanced feedback.
OVERCOMING BARRIERS TO NEW LEARNING TECHNOLOGIES IN A UNIVERSITY SETTING: THE CASE OF COVENANT UNIVERSITY

Covenant University aspires to be one of the ten leading university in the world by 2022. To achieve this noble goal, the university has set in motion various strategies, some of which are to improve the learning process of students, empowerment of faculty and staff in gaining skills in teaching methodologies and the use of e-learning/new technologies. The university has currently invested a lot of funds in the acquisition of relevant and contemporary e-learning technologies, such as teleconferencing centres (five in all), e-learning lecture and delivery and assessment platforms (e.g. Moodle, TurnitinTM, et cetera), Smart interactive digital boards, fully digitized podiums etc. In a bid to maximize these investments, the need for identifying and addressing teachers’ phobia and demonstrated barriers to the new technologies and aids becomes imperative. The barriers to the use of appropriate teaching methodologies and the use of new technologies relevant to teaching were identified. The paper focused mainly on barriers related to lack of awareness of effective teaching methodologies, non-availability of appropriate e-learning/new technologies and psychological barriers to effective use of new technologies currently in use. The paper also highlights efforts made by the institution in acquiring new technologies applied to education, sensitisation of faculty and staff to the effects of teaching pedagogies in the educative process and the personality factors in the utilisation of new technologies.
Maximizing the GPU resource usage by reordering concurrent kernels submission

The increasing amount of resources available on current GPUs sparked new interest in the problem of sharing its resources by different kernels. While new generations of GPUs support concurrent kernel execution, their scheduling decisions are taken by the hardware at runtime. The hardware decisions, however, heavily depend on the order at which the kernels are submitted to execution. In this work, we propose a novel optimization approach to reorder the kernels invocation focusing on maximizing the resources utilization, improving the average turnaround time. We model the kernel assignments to the hardware resources as a series of knapsack problems and use a dynamic programming approach to solve them. We evaluate our method using kernels with different sizes and resource requirements. Our results show significant gains in the average turnaround time and system throughput compared to the kernels submission implemented in modern GPUs.
The application of artificial neural networks to the analysis of remotely sensed data

Artificial neural networks (ANNs) have become a popular tool in the analysis of remotely sensed data. Although significant progress has been made in image classification based upon neural networks, a number of issues remain to be resolved. This paper reviews remotely sensed data analysis with neural networks. First, we present an overview of the main concepts underlying ANNs, including the main architectures and learning algorithms. Then, the main tasks that involve ANNs in remote sensing are described. The limitations and crucial issues relating to the application of the neural network approach are discussed. A brief review of the implementation of ANNs in some of the most popular image processing software packages is presented. Finally, we discuss the application perspectives of neural networks in remote sensing image analysis.
Maximizing downlink bandwidth allocation method based on SVC in Mobile WiMAX networks for generic broadband services

This paper proposes an adaptive downlink bandwidth allocation method (DBAM) for six traffic types--UGS, RT-VR, ERT-VR, NRT-VR, BE, and multicast--to maximize the throughput of broadband WiMAX networks for generic broadband services. Based on traffic throughput and the amount of traffic in different scalable video coding (SVC) layers, two adaptive resource adjustment schemes with SVC technology in the DBAM are proposed and compared. Moreover, a hierarchical priority queuing for different traffic profiles with weighted round robin (HPWRR) scheduling algorithm is proposed to achieve higher resource utilization and to meet the required quality of service (QoS) for each traffic type. Simulation results show that the proposed DBAM with HPWRR can achieve efficient throughput and bandwidth utilization and improve the delay time for RT-VR and multicast traffic.
Eğitim ve Fen Edebiyat Fakültesi Öğrencilerinin Öz-Yeterlik İnançları ve Öğretmenlik Mesleğine Karşı Tutumlarının İncelenmesi

The purpose of this study was to examine education and arts and science faculty preservice students' self-efficacy beliefs and their attitudes toward teaching profession and also to explore whether the self efficacy belief is a significant predictor of attitude toward teaching or not. The research was based on the relational survey model. The sample of the study consists of 411 pre-service students attending education and arts and science faculty of Ankara, Gazi, Hacettepe and Aksaray University. Data was collected by “Self-Eficacy Scale” and “Attitude Toward Teaching Profession Scale”. Data were analyzed through ttest, Pearson Correlation Coefficient and multiple regression analyses. The research findings show that the perceptions of the faculty of education pre-service students’ selfefficacy beliefs are higher than that of the faculty of arts and science students. However, arts and sciences faculty pre-service students’ perception of attitude toward teaching was found higher than that of education faculty students. Additionally, research revealed that attitude toward teaching profession was not a significant predictor of self efficacy
Bevacizumab for the Treatment of Macular Edema

Background: anti-vascular endothelial growth factor (anti-VEGF) has been suggested for the treatment of macular edema. In this study we are assessing the efficacy of one type of anti-vascular endothelial growth factor which is Bevacizumab (Avastin) in the reduction of macular thickness. Patients and Methods: from the period of February 2012 to February 2015, we have gathered the data of 54 patients (39=males, 15 =females) suffering from macular edema who received variable number of intraocular injections of Bevacizumab to be included in a retrospective study. One eye from each patient was chosen randomly and then we observe their follow-up Optical Coherence Tomography (OCT) for any changes in the thickness of the macula. Results: after receiving a single Bevacizumab injection, 16 patients (29.6%) did not show any improvement while 22 (40.7%) patients show an improvement that was less than 50 microns of reduction in magnitude, 5 patients (9.2%) showed an improvement that was greater than 50 microns in reduction of macular thickness and the remaining 11 patients (20.3%) had a reduction of macular thickness that was greater than 100 microns. Conclusion: despite being used originally for metastatic colon cancer, Bevacizumab (Avastin) can be used in the treatment of diabetic macular edema.
Three-dimensional face imaging and recognition: a sensor design and comparative study

Many commercially available 3D sensors suitable for face image capture employ passive or texture-assisted stereo imaging or structured illumination with a moving light stripe. These techniques require a stationary subject. We describe a design and evaluation of a fixed-stripe, moving object 3D scanner designed for human faces, called the Static Light Screen (SLS) Scanner (Patent Pending). Our method of acquisition requires the subject to walk through a light screen generated by two laser line projectors. Triangulation and tracking applied to the video sequences captured during subject motion yield a 3D image of the subject's face from multiple images. To demonstrate the accuracy of our initial design, a small-scale facial recognition experiment was executed. In an experiment with 476 images of 161 unique subjects, we achieved 46.3% rank-one recognition using an Iterative Closest Point (ICP) based matching method, demonstrating the feasibility of the technique. This is the subset of our full SLS dataset with 2270 images of 379 unique subjects, which has a subject velocity less than 0.33 m/s. We also developed techniques to improve face recognition based on ICP using fusion techniques and score normalization techniques. We improved rank-one recognition on a data set (FRGC v2) of 4007 faces of 466 unique subjects from 96.4% rank-one recognition to 98.6%.
How to dissect surgical journals: VI – Data

John Arbuthnot observed that there were more males than females christened in London between 1629 and 1710. He concluded that this was more than coincidence, and stated that ‘it is art, not chance, that governs’. This application of probability to social statistics, in the eyes of some numerists, makes Arbuthnot the father of nonparametric statistics (nonparametric statistics do not assume that the measurements have an underlying distribution i.e., they are ‘distribution-free’ statistics). There followed an era that sought to use numbers to describe natural events. Carl Fredrick Gauss (1777–1855) described a ‘bellshaped’ distribution based on a study of observational errors in astronomy (Figure 1). It is centred on the belief that there is symmetry in the universe with a tendency towards the average accompanied by progressively diminishing tails on each side. This mathematical model was thought to represent the usual variation found in nature. It is often referred to as the ‘normal distribution’. This concept was grasped by the Belgian polymath Adolphe Quetelet (1796–1874) who promoted the concept of ‘the average man’ (l’homme moyen). He analysed the heights of 100,000 conscripts in the French army and estimated that a number of men were avoiding active service by being inappropriately classified below the minimum height requirement. Progress saw the focus of research shifted away from the purely demographic to embrace the concept of scientific investigation. As Claude Bernard put it in 1865 ‘scientific medicine, like the other sciences, can be established only by experimental means i.e., by direct and rigorous applications of reasoning to the facts furnished us by observation and experiment’. Bernard had concerns about statistics and averaging, which he disparaged by the tale of ‘a physiologist who took urine from a railway station urinal where people of all nations passed, and who believed he could thus present an analysis of average European urine! ’.
Structure et identité des styles céramiques du Néolithique ancien entre Rhône et Èbre

L'avancee des recherches n 'a de cesse de demontrer l'important polymorphisme caracterisant les premieres societes agropastorales du sud de la France et, a une echelle plus large, de la Mediterranee occidentale. La constitution d'un corpus de reference d'assemblages ceramiques homogenes et le traitement de leurs caracteristiques stylistiques par le biais de l'analyse quantitative ont permis de proposer un nouveau cadre chronoculturel du Neolithique ancien entre Rhone et Ebre. Le schema developpe comporte trois grandes phases chronologiques. La premiere phase voit l'implantation des facies a ceramiques imprimees sur les cotes languedociennes et catalanes. Ils s 'expriment au travers de caracteristiques stylistiques variees qui suggerent la multiplicite de leur origine. La deuxieme phase identifiee voit l'evolution en parallele de deux styles ceramiques, Cardial recent et epicardial ancien, dont l'origine et la nature sont discutees. La troisieme et derniere phase chronologique voit, au contraire de la precedente, une homogeneisation stylistique de la decoration ceramique. La repartition geographique de l'epicardial recent montre l'exploitation de territoires de plus en plus eloignes du littoral. On observe enfin une consolidation du systeme economique et les premices de certains reseaux d'echanges qui connaitront leur apogee au quatrieme millenaire avant notre ere.
Compiling to the gate level for a reconfigurable co-processor

This paper describes a programmable coprocessor. A C-compiler has been written which compiles C code to the gate level relieving the programmer of the onerous task of programming the coprocessor. As not all of the code in most C programs will fit into the coprocessors FPGA, programs are first compiled using a standard C compiler. These programs are then profiled to determine which parts of the code make the most intense use of the processor. These parts are then compiled to the gate level and implemented in the coprocessor. Speedups in program execution time of about 20 are obtained by this method by comparison with an IPC Sparcstation. <<ETX>>
