Tunnel Magnetoresistance Properties of Double MgO-Barrier Magnetic Tunnel Junctions With Different Free-Layer Alloy Compositions and Structures

We investigated tunnel magnetoresistance (TMR) properties in double MgO-barrier magnetic tunnel junctions (DMTJs) with (Co<sub>25</sub>Fe<sub>75</sub>)<sub>100-x</sub>B<sub>x</sub> free-layers with <i>x</i> = 15, 20, and 25 (in at.%) sputtered at different power. The TMR ratio of DMTJs increased with sputtering power, which is ascribed to the B composition reduction in the CoFeB free-layer with increasing sputtering power. The x-ray diffraction measurement showed that crystallization into (001)-oriented texture of CoFeB film sandwiched between the two MgO-layers as well as an improvement of (001) orientation of top MgO-barrier are realized. The TMR ratio over 200% was obtained in DMTJs with a (Co<sub>25</sub>Fe<sub>75</sub>)<sub>85</sub>B<sub>15</sub> free-layer sputtered at 0.88 and 1.77 W/cm<sup>2</sup>.
Dialect and point of view: The ideology of translation in

This article is an analysis of translations into French of non-standard literary dialect, in particular the speech of African Americans, in William Faulkner’s The sound and the fury. It shows that the contingency of dialect variation upon narrative point of view (focalization) is not taken into account in translation, an omission that alters the ideological framework of the novel. In addition, it argues that the maintenance of this variation, when systematic, should be at least as important a concern as, for instance, the most accurate translation of single dialectal or non-standard words and utterances.
Pathological Lying, Accusation, and Swindling: A Study in Forensic Psychology

ions. There were evidences of degeneracy on the mother's side. Remedies in education for such children are: Suppress food for imagination, such as came from the stories of father and brother. Direct perceptions to accurate work. Systematize education of attention, exercise the senses, use manual work, such as modeling and gardening. Give lessons in observation in the class room and on promenades. Meunier[23] tells of three girls in a well known Parisian school who indulged in wonderful tales. The first, in the intermediate grade, told stories of the illness of her father to account for her not having her lessons. The second, 11 years old, said that her mother was dying; she came bringing this news to the teachers at two different periods of her school life. She was a calm, thoughtful, analytical child with no reason for lying. Family history negative. The third, 13 years old, told of an imaginary uncle who was going to collect funds for needy children; she kept up the deceit for two months. She was an anemic, nervous, hysterical child with a nervous mother. Meunier calls these cases of systematized deliriums. The development of such delirium annihilates, so to speak, the entire personality of the subject, and his entire mental life is invaded by abnormal extra and introspection--the delirium commands and systematizes all acquired impressions. There is a veritable splitting of the personality in which the new ``ego'' is developed at the expense of the normal ``ego'' that now only appears at intervals.

This paper reports on an exploratory study to assess the present status of the Requirements Engineering course offered in major public universities in Malaysia. The main instrument used to gather data was the questionnaire. 47 responses were received and analyzed. The results from the questionnaire were discussed and compared with the problems presented in Requirements Engineering Education Literature.
On the Shores of Politics

It is frequently said that we are living through the end of politics, the end of social upheavals, the end of utopian folly. Consensual realism is the order of the day. But political realists, remarks Jacques Ranciere, are always several steps behind reality, and the only thing which may come to an end with their dominance is democracy. 'We could', he suggests, 'merely smile at the duplicity of the conclusion/suppression of politics which is simultaneously a suppression/conclusion of philosophy. ' This is precisely the task which Ranciere undertakes in these subtle and perceptive essays. He argues persuasively that since Plato and Aristotle politics has always constructed itself as the art of ending politics, that realism is itself utopian, and that what has succeeded the polemical forms of class struggle is not the wisdom of a new millennium but the return of old fears, criminality and chaos. Whether he is discussing the confrontation between Mitterrand and Chirac, French working-class discourse after the 1830 revolution, or the ideology of recent student mobilizations, his aim is to restore philosophy to politics and give politics back its original and necessary meaning: the organization of dissent.
Tooth sensitivity experience among residential university students.

OBJECTIVES The aim of this study was to assess the experience of residential University students about 'sensitive teeth'. SUBJECT AND METHODS Self-administered questionnaires were given randomly to students in all the residential hostels located in the University campus. Data on presence of sensitive teeth, initiating stimulus and duration of each episode of discomfort were elicited. History of common aetiological factors of tooth sensitivity was also taken. RESULTS One thousand and nineteen responses (650 males; 369 females) were analysed in this study. Approximately 697 (68.4%) volunteers claimed to have sensitive teeth. Majority described their discomfort as sharp pain, cold as the initiating stimulus and drinking was mostly interfered with. Tooth sensitivity was found to be common among hard toothbrush users. Multiple regression analysis showed that hard toothbrush had a significant association with tooth sensitivity. Other common aetiological factors, such as history of gastric acid reflux, vomiting, soft drinks and the use of vitamin C were found to have a weak association with tooth sensitivity. CONCLUSION Prevalence of tooth sensitivity was 68.4%. Presence of tooth sensitivity among these students was associated more with history of hard toothbrush use contrary to widely held belief that erosive agents were mostly responsible. Future studies are needed to provide more epidemiological data on tooth brushing and tooth sensitivity.
The personal and professional characteristics and patterns of work of itinerant teachers of the deaf and hard of hearing in Australia.

A survey of itinerant teachers of the deaf and hard of hearing in four Australian states raw conducts to describe the personal and professional characteristics of these teachers and their rank with students. Of particular interest raw whether itinerant teachers use consultative or pull-out models of service delivery. Other elements surveyed included professional training and backgrounds of the teachers, their experience in regular and special education, the basis of their workload determination, the roles they adopt to meet the perceived needs of their students, and factors which influenced their perceptions of the effectiveness of service delivery. The implications of these findings for policy development and service delivery are discussed.
A Comparison of SVM Versus Naive-Bayes Techniques for Sentiment Analysis in Tweets: A Case Study with the 2013 FIFA Confederations Cup

The widespread of social communication media on the Web has made available a large volume of opinionated textual data stored in digital format. These media constitute a rich source for sentiment analysis and understanding of the opinions spontaneously expressed. Traditional techniques for sentiment analysis are based on POS Tagger. Considering the Portuguese language, the use of POS Tagging ends up being too costly, due to the complex grammatical structure of this language. Faced with this problem, a case study is carried out in order to compare two techniques for sentiment analysis: a SVM versus Naive-Bayes classifiers. Our study focused on tweets written in Portuguese during the 2013 FIFA Confederations Cup, although our technique could be applied to any other language. The achieved results indicated that the SVM technique surpassed the Naive-Bayes one, concerning performance issues.
Optimal Yaw Regulation and Trajectory Control of Biorobotic AUV Using Mechanical Fins Based on CFD Parameterization

This paper treats the question of control of a biorobotic autonomous undersea vehicle (BAUV) in the yaw plane using a biomimetic mechanism resembling the pectoral fins of fish. These fins are assumed to undergo a combined sway-yaw motion and the bias angle is treated as a control input, which is varied in time to accomplish the maneuver in the yaw-plane. The forces and moments produced by the flapping foil are parametrized using computational fluid dynamics. A finite-difference-based, Cartesian grid immersed boundary solver is used to simulate flow past the flapping foils. The periodic forces and moments are expanded as a Fourier series and a discrete-time model of the BAUV is developed for the purpose of control. An optimal control system for the set point control of the yaw angle and an inverse control law for the tracking of time-varying yaw angle trajectories are designed. Simulation results show that in the closed-loop system, the yaw angle follows commanded sinusoidal trajectories and the segments of the intersample yaw trajectory remain close to the discrete-time reference trajectory. It is also found that the fins suitably located near the center of mass of the vehicle provide better maneuverability.
Employee participation in organizational change : Investigating the effects of proactive vs. reactive implementation of downsizing in Swedish hospitals

Whereas employee participation is generally conceived to facilitate implementation of organizational change, only limited research has investigated whether it may reduce the negative effects of downsizing. The present study compares two Swedish hospitals that implemented downsizing in different ways. While there were no major differences in stressors between hospitals, proactive implementation was associated with more employee participation. Moreover, employee participation variables were positively associated with employee work attitudes and well-being at both hospitals. These findings provide insights concerning the importance of a long-term strategic implementation of organizational change.
A* Algebra for an Extended Object/Relational Model

The object relational data model presents both the advantage of Codd's relational calculus power and the characteristics of the object orientation . T wo major approaches have been adopted to satisfy the requirements of new databases applications. A first approach integrates the object characteristics into the new data models with the specification of data constraints and the definition of interrogation language. The second one, called evolutionary approach, keeps Codd's data model enriching with adequate concepts for the coverage of current database applications. In this approach and comparatively with studies presented by Melton, Date and Darwen have proposed the foundations of the object relational model. So, A-algebra consisting of first order logic operators has been defined to express various classes of queries in object relational database. To contribute to the improvement of relational/ob ject models and agebra this paper presents an extension of object relational model to new types generated by operators and the related A*algebra. These operators, called Op, offer a means to specify domains as functions and permit consequently to increase the data model expressiveness. To support this extension, we propose a new data query language, or more precisely a logical data calculation A* as an adapatation of the A-algebra. Our A*-algebra contains algebraic operators which are able to support this new extension.
The combing optimizer

This paper introduces a novel heuristic search and optimization algorithm in order to find the maximum/minimum values of mathematical functions, by mimicking a certain community behavior seen in human beings. The intense search procedure in selected search areas followed by soldiers/policemen while capturing convicts/terrorists is followed here. Initial results obtained for some benchmark functions are reported. This algorithm has been seen to achieve significant improvement in efficiency, over several popular optimization algorithms in terms of the number of function evaluations.
ABO-INCOMPATIBLE HEART TRANSPLANTATION IN INFANTS: THE FREEMAN HOSPITAL EXPERIENCE

Background. Incompatibility of the major blood groups A, B, and O has been an absolute contraindication for heart transplantation. However, because of immunologic immaturity, infants may have relative protection from hyperacute rejection and thus could undergo transplantation with ABO-mismatched organs. Methods. Since January 2000, the authors have adopted a policy of considering infants for ABO-incompatible heart transplantation. Serum isohemagglutinin titers were measured before, during, and after transplantation. Two infants (3 and 2 months old) and a 21-month-old child underwent ABO-incompatible heart transplantation. During cardiopulmonary bypass, plasma exchange was performed. No other antibody-removal procedures were performed. A routine immunosuppressive regimen was used, and rejection was monitored by endomyocardial biopsies. An additional two patients (31 and 18 months old) were worked up but were unsuitable for ABO-incompatible transplantation because of high isohemagglutinin titers. They were successfully bridged to transplantation and received heart transplants from ABO-compatible donors. Results. All three infants with ABO-incompatible heart transplants are fit and well, 40 months, 30 months, and 12 months postoperatively. All three had serum antibodies to antigens of the donor’s blood group before transplantation. No hyperacute rejection occurred. No morbidity attributable to the ABO incompatibility has been observed. Conclusions. ABO-mismatched heart transplantation may be undertaken safely and without any short-term adverse consequences in infants and young children in whom isohemagglutinin production is not yet established.
Semen quality of male partners of infertile couples in Ile-Ife, Nigeria.

OBJECTIVES The objective was to evaluate seminal fluid indices of male partners of infertile couples so as to identify the current status of the contributions of male factor to infertility in our environment. MATERIALS AND METHODS This is a prospective study of the seminal fluid indices of consecutively consenting male partners of infertile couples seen at the Fertility and Endocrinology Research unit of the Department of Obstetrics Gynaecology and Perinatology, Obafemi Awolowo University Teaching Hospital Ile-Ife between May 2004 and June 2008. RESULTS The results of the semen analysis of 661 male partners of the infertile couples were retrieved and analyzed. The patterns of semen parameters noted in infertile males were oligozoospermia, teratozoospermia, asthenozoospermia, azoospermia, oligoteratozoospermia, oligoasthenozoospermia, and oligoasthenoteratozoospermia, asthenoteratozoospermia found in 25.6%, 18.5%, 11.5%, 6.2%, 3.2%, 2.3%, 2.1%, and 0.9%, respectively. Among the age groups, age group 31-40 had a higher prevalence of oligozoospermia (13.3%) while among the occupational groups, the civil servants had the highest prevalence of oligozoospermia (12%). There was a high of level of leucocytospermia and bacterial infections in both normospermic and oligospermic semen. CONCLUSION This study showed a high rate of abnormal semen quality of male partners of infertile couple in our environment and is an indication for the need to focus on the management of this condition and the institution of preventive program for male infertility. There is urgent need for advocacy for men to accept responsibility for their contribution to infertility and to reduce stigmatization and ostracizing of women for infertility.
MULE: Multi-layer virtual network embedding

Network Virtualization (NV), considered as a key enabler for overcoming the ossification of the Internet allows multiple heterogeneous virtual networks to co-exist over the same substrate network. Resource allocation problems in NV have been extensively studied for single layer substrates such as IP or Optical networks. However, little effort has been put to address the same problem for multi-layer IP-over-Optical networks. The increasing popularity of multi-layer networks for deploying backbones combined with their unique characteristics (e.g., topological flexibility of the IP layer) calls for the need to carefully investigate the resource provisioning problems arising from their virtualization. In this paper, we address the problem of MUlti-Layer virtual network Embedding (MULE) on IP-overOptical networks. We propose two solutions to MULE: an Integer Linear Program (ILP) formulation for the optimal solution and a heuristic to address the computational complexity of the optimal solution. We demonstrate through extensive simulations that on average our heuristic performs within ≈1.47 × of optimal solution and incurs ≈66% less cost than the state-of-the-art heuristic.
Pericyte-Derived MFG-E8 Regulates Pathologic Angiogenesis

Objective— MFG-E8 (also called lactadherin and SED1) is a secreted glycoprotein that has been previously implicated in enhancement of vascular endothelial growth factor–dependent angiogenesis. Major sources of MFG-E8 in vivo and precise mechanisms of MFG-E8 action remain undetermined. The objective of this study was to identify important sources of MFG-E8 in vivo and further elucidate the role(s) of MFG-E8 in the regulation of angiogenesis. Methods and Results— We used knockout mice and anti-MFG-E8 antibodies to study MFG-E8 function in vivo. In melanomas and in retinas of mice with oxygen-induced retinopathy, MFG-E8 colocalized with pericytes rather than endothelial cells, and platelet-derived growth factor receptor &bgr;+ pericytes/pericyte precursors purified from tumors contained large amounts of MFG-E8 mRNA. Tumor- and retinopathy-associated angiogenesis was diminished in MFG-E8 knockout mice, and pericyte coverage of neovessels was reduced. Inhibition of MFG-E8 production by 10T1/2 cells (surrogate pericyte/pericyte precursors) using small interfering RNAs and short hairpin RNAs, or inhibition of MFG-E8 action with some anti-MFG-E8 antibodies, selectively attenuated migration in vitro. Significantly, the anti-MFG-E8 antibodies that inhibited 10T1/2 cell migration in vitro also inhibited pathological angiogenesis in vivo. Conclusion— These studies strongly implicate MFG-E8 in pericyte/pericyte precursor function and indicate that MFG-E8-directed therapeutics may merit further development.
Adaptive Differential Visual Feedback for Uncalibrated Hand-Eye Coordination and Motor Control

We propose and implement a novel method for visual space trajectory planning, and adaptive high degree-of-freedom (DOF) visual feedback control. The method requires no prior information either about the kinematics of the manipulator, or the placement or calibration of the cameras, and imposes no limitations on the number of degrees of freedom controlled or the number of kind of visual features utilized. The approach provides not only a means of low-level servoing but a means to integrate it with higher level visual space trajectory and task planning. We are thus able to specify and perform complex tasks composed of several primitive behaviors, using both visual servoing and open loop control, where the number of sensed and controlled signals varies during the task. We report experimental results demonstrating a factor of 5 improvement in the repeatability of manipulations using a PUMA arm when comparing visual closed-loop to traditional joint level servoing. We also present experiment statistics showing the advantages of adaptive over non-adaptive control systems, and of using redundant visual information when performing manipulation tasks. Finally, we demonstrate usefulness of the approach by using it to specify and execute complex tasks involving real-world robot manipulation of rigid and non-rigid objects in up to 12 degrees of freedom. The manipulation is performed in the context of a semi-autonomous robot manipulation system.
In defence of deliberative democracy : challenging less democratic school governing body practices

One of the major features of the democratisation of education in South Africa revolves around the decentralisation of school governance. In this regard important decision-making responsibilities have devolved from central government to "self-governing" school communities, incorporated into School Governing Bodies (SGBs). The study explores current practices of SGBs in se lected schools in the Grassy Park area of the Western Cape. It seeks to demonstrate that a dichotomy appears to exist between the ideals of democratic policies as espoused in the South African Schools Act of 1996 and the manner in which these democratic ideals / policies are interpreted / implemented. The promulgation of the South African Schools Act of 1996 heralded the beginning of a new phase in the governance of schools. However, the mere promulgation of policy does not necessarily imply its effective implementation. It is argued that despite the existence of the South African Schools Act (SASA), school governing practices do not seem to be conclusively democratic. Unless school governing practices are reconceptualised and restructured in accordance with a notion of deliberative democracy, such practices will continue to remain less democratic.
Dietary fat alters the response of hypothalamic neuropeptide Y to subsequent energy intake in broiler chickens

ABSTRACT Dietary fat affects appetite and appetite-related peptides in birds and mammals; however, the effect of dietary fat on appetite is still unclear in chickens faced with different energy statuses. Two experiments were conducted to investigate the effects of dietary fat on food intake and hypothalamic neuropeptides in chickens subjected to two feeding states or two diets. In Experiment 1, chickens were fed a high-fat (HF) or low-fat (LF) diet for 35 days, and then subjected to fed (HF-fed, LF-fed) or fasted (HF-fasted, LF-fasted) conditions for 24 h. In Experiment 2, chickens that were fed a HF or LF diet for 35 days were fasted for 24 h and then re-fed with HF (HF-RHF, LF-RHF) or LF (HF-RLF, LF-RLF) diet for 3 h. The results showed that chickens fed a HF diet for 35 days had increased body fat deposition despite decreasing food intake even when the diet was altered during the re-feeding period (P<0.05). LF diet (35 days) promoted agouti-related peptide (AgRP) expression compared with HF diet (P<0.05) under both fed and fasted conditions. LF-RHF chickens had lower neuropeptide Y (NPY) expression compared with LF-RLF chickens; conversely, HF-RHF chickens had higher NPY expression than HF-RLF chickens (P<0.05). These results demonstrate: (1) that HF diet decreases food intake even when the subsequent diet is altered; (2) the orexigenic effect of hypothalamic AgRP; and (3) that dietary fat alters the response of hypothalamic NPY to subsequent energy intake. These findings provide a novel view of the metabolic perturbations associated with long-term dietary fat over-ingestion in chickens. Summary: Hypothalamus-based self-adjustment in response to dietary fat can vary among lean and fat individuals, and depends upon whole-body energy reserves and feeding experience.
