A QSO survey via optical variability and zero proper motion in the M 92 field. I. QSO candidates and selection effects

The combination of variability and proper motion constraints (VPM search) is believed to provide an unconventional yet ecient search strategy for QSOs with selection eects quite dierent from conventional optical QSO surveys. Previous studies in a eld of high galactic latitude have shown that the VPM method is indeed an ecient search strategy. In the present paper, we describe a further variability-proper motion (VPM) QSO survey on Tautenburg Schmidt plates. The survey is based on an exceptionally large number of 162 B plates centred on M 92 with a time-baseline of more than three decades. Further U and V plates are used to measure time-averaged colour indices, and morphology is evaluated on a deep R plate. Proper motions with Hipparcos -like accuracies as well as variability indices are derived for about 35 000 star-like objects down to B =2 0:5. With regard to both the number of plates and the number of objects to be investigated, this is the largest VPM survey performed so far. The present paper is focused on the description of the observational material, the data reduction, the denition of the selection parameters, and the construction of the QSO candidate sample. Furthermore, the selection eects of the VPM-method are discussed a priori. For the present survey, the selection eects are shown to be dominated by the magnitude-dependence of the photometric accuracy. Down to the limiting magnitude of the survey Blim =1 9:7, we identify 62 high-priority QSO candidates and a further 57 candidates of medium priority. Spectroscopic follow-up observations have been performed for all these candidates as well as for additional selected candidates of lower priority; the conrmed QSOs will be presented and discussed in a forthcoming paper.
RDF Resources of Saudi Open Data

Different organizations and governments are working toward publishing their data on the web to achieve a variety of goals. Published data facilitate transparency and cooperation. Currently, most of the data available on the web are not easily accessible, which limits their application. The Semantic Web technology standards are used to access data with a specific representation: Resource Description Framework (RDF). Some published data require transformation to the Semantic Web standard formats to ensure that they are accessible. This work investigates Saudi open data and provides an algorithm to generate RDF resources. Additionally, some recommendations and analyses are discussed.

On the stationary Navier-Stokes flow with isotropic streamlines in all latitudes on a sphere or a 2D hyperbolic space

In this paper, we show the existence of real-analytic stationary Navier-Stokes flows with isotropic streamlines in all latitudes in some simply-connected flow region on a rotating round sphere. We also exclude the possibility of having a Poiseuille's flow profile to be one of these stationary Navier-Stokes flows with isotropic streamlines. When the sphere is replaced by a 2-dimensional hyperbolic space, we also give the analog existence result for stationary parallel laminar Navier-Stokes flows along a circular-arc boundary portion of some compact obstacle in the 2-D hyperbolic space. The existence of stationary parallel laminar Navier-Stokes flows along a straight boundary of some obstacle in the 2-D hyperbolic space is also studied. In any one of these cases, we show that a parallel laminar flow with a Poiseuille's flow profile ceases to be a stationary Navier-Stokes flow, due to the curvature of the background manifold.
AUTOMATIC CLASSIFICATION USING GROWING SELF-ORGANISING NEURAL NETWORKS IN ASTROPHYSICAL EXPERIMENTS

Self-Organising Map (SOM), an unsupervised neural network, has proved to be very efficient in classification problems. In recent years Dynamic Growing Neural Networks , based on SOM , have been developed. Automatic Classification (also called as clustering) is an important and a difficult problem in many Astro-Physical experiments, for instance, Gamma Ray Bursts Classification, Separation of Gamma from the Hadron. After a brief introduction to classification problem, we discuss Self-Organising Maps in section 2. Section 3 discusses with various models of growing neural networks and finally in section 4 we discuss the research perspectives in growing neural networks for efficient classification.
A PRELIMINARY STUDY ON ADOPTING SIX-SIGMA QUALITY MEASUREMENT FOR APTS TECHNOLOGY OUTPUTS

Six-sigma quality means a failure rate of 3.4 defects per million process opportunities; however, the term in practice is used to denote more than simply counting defects. Six-sigma can now imply a whole culture of strategies, tools, and statistical methodologies to improve the bottom line of any operations. Achieving the six-sigma level means cutting down huge costs and thereby the wasted dollars. Studies associated with public transportation service performances always focus on the passenger’s perspectives, i.e. comfort and time saving of passengers. However, the evaluation would be somehow from an operator’s/provider’s view, means that the evaluation focus could be like that of manufacturing, i.e. the providing/production reliability. To evaluate those reliability qualities, six-sigma approach could be an alternative. Therefore, this study proposes some Advanced Public Transportation System (APTS) technologies possibly for the pilot six-sigma quality measurement.
In Vitro Evolution of RNA Binding Peptides for Increased Specificity

The Hepatitis C Virus internal ribosme entry site (HCV IRES) is an attractive target for inhibition of HCV translation. Using peptides that we selected to bind P6.1, a domain of human telomerase RNA, we perform mutagenic PCR and additional cycles of selection to isolate sequences that bind to P6.1 and to domain IIId of the HCV IRES. The P6.1-binding sequences are highly specific for their target but the HCV IIId-binding sequences bind to both P6.1 and domain IIId. Our data show that although only a few positions are necessary for RNA binding specificity, these mutations are relatively rare.
Searching for Gravitational Waves from Sub-Solar Mass Black Holes

We are searching for gravitational-wave signals from sub-solar mass black hole binary systems in initial Laser Interferometer Gravitational-wave Observatory (LIGO) data. The most likely candidates for such systems are primordial black holes that have formed from the collapse of quantum fluctuations in the early universe. Primordial black holes have not yet been ruled out by microlensing experiments, but the allowable masses have been restricted. The gravitational- wave strain from such an inspiralling binary system is well modeled with the post- Newtonian formalism. Therefore, a modeled search for gravitational-wave signals is employed. The search technique is known as matched filtering and is implemented using a codebase that is well-suited for fast searches with long signals. One of the biggest challenges in performing this search is dealing with the heavy computational burden. The gravitational-wave signals from such low-mass binary systems are long (about 10 minutes) and require a large number of models, or templates, spread across the parameter space. A large effort has been focused on speeding up the search while using a reasonable amount of computational resources.
Cultural Heritage: An example of graphical documentation with automated photogrammetric systems

In the field of Cultural Heritage, the use of automated photogrammetric systems, based on Structure from Motion techniques (SfM), is widely used, in particular for the study and for the documentation of the ancient ruins. This work has been carried out during the PhD cycle that was produced the "Carta Archeologica del territorio intorno al monte Massico". The study suggests the archeological documentation of the mausoleum "Torre del Ballerino" placed in the south-west area of Falciano del Massico, along the Via Appia. The graphic documentation has been achieved by using photogrammetric system (Image Based Modeling) and by the classical survey with total station, Nikon Nivo C. The data acquisition was carried out through digital camera Canon EOS 5D Mark II with Canon EF 17–40 mm f/4L USM @ 20 mm with images snapped in RAW and corrected in Adobe Lightroom . During the data processing, the camera calibration and orientation was carried out by the software Agisoft Photoscans and the final result has allowed to achieve a scaled 3D model of the monument, imported in software MeshLab for the different view. Three orthophotos in jpg format were extracted by the model, and then were imported in AutoCAD obtaining facade’s surveys.
Service Encounters as a Sequence of Events

A service encounter can be considered as a sequence of events. In the early service literature, it was assumed that firms should deliver a consistent performance during a service encounter. However, research in psychology states that this is not necessarily true. In addition to the average performance, the peaks in the performance are important. Likewise, some service researchers have stressed the importance of a happy ending. The authors test a model on how events contribute to the overall evaluation of a sequence of events. They show that the average performance during the encounter is important. However, their results also stress the importance of peak experiences for satisfaction formation. Thus, managers of service encounters should not only manage the overall performance of a service encounter. To further elevate satisfaction, they could also provide some positive peak experiences.
Use of bioagents and synthetic chemicals for induction of systemic resistance in tomato against diseases.

Plants and pathogens have developed an intricate relationship based on mutual information. Pathogens develop various strategies to attack successfully plants and in return, plants develop strategies to protect themselves from pathogens. Over the last two decades, a number of approaches have been applied by pathologists to enhance disease resistance in plants. Among these, induction of systemic resistance as an integrated control strategy offers exciting opportunities. Induced resistance (IR) could be developed by two main mechanisms: Systemic acquired resistance (SAR) and induced systemic resistance (ISR). Systemic acquired resistance (SAR) is a phenomenon by which a plant activates its own defense under the influence of a bio-agent or a chemical. This resistance develops with changes in the biochemistry and physiology of the cell that is further accompanied by structural modifications in the plants that act as physical barriers to restrict pathogen penetration. It is effective under field conditions and is a natural mechanism for bio-control of plant diseases. Scientists have used several agents to induce systemic resistance in tomato including bacteria, fungi and chemicals. Major areas discussed in this paper are historical background, mechanism of IR and its induction in tomato by various bio-agents and chemicals.
Development of Dual-memory Motor Drives for Electric Vehicles

AbstractThis paper proposes a dual-memory motor drive for electric vehicles (EVs). The dual-memory motor adopts a dual-magnet arrangement which incorporates two permanent magnet materials for hybrid excitation, namely neodymium-iron-boron (NdFeB) and aluminum-nickel-cobalt (AlNiCo). The NdFeB PMs provides the main air-gap flux, while the AlNiCo PMs can be regulated online for main flux strengthening or weakening. Therefore, the dual-memory motor drives can achieve a high starting torque by flux strengthening and extend its constant power operation range by flux weakening. Firstly, the proposed motor structure is presented. Secondly, its operation principle is discussed. Thirdly, the drive system and control scheme are developed for EVs. Finally, by using the circuit-field-torque time-stepping finite element method (CFT-TS-FEM), the performance of flux strengthening is verified, and experiments are also carried out to assess its flux weakening capability.

A lo que ellas juegan: la experiencia de jugar videojuegos y su relación con la producción de significado, el caso de las videojugadoras mexicanas

Este proyecto explora diferentes tipos de experiencias significativas detonadas por el hecho de jugar videojuegos. Se eligio estudiar a videojugadoras mexicanas no por una perspectiva de genero, sino por el hecho de que son una minoria dentro de casi todos los ambitos del videojuego. Interesa saber a que campos de la vida de estas mujeres llega la influencia del hecho de jugar. La investigacion se construye sobre la interpretacion de los discursos que las videojugadoras reportan sobre sus experiencias de juego. A partir de la hipotesis general de que estas experiencias tienen significaciones que impactan en la vida de las jugadoras, se realizo un seguimiento sin categorias definidas a priori para poder observar cuales son los elementos que los propios sujetos reportan como importantes en su experiencia. Como es su negociacion con lo experimentado en el juego y lo que viven fuera de este y viceversa? El trabajo se apoya en investigaciones teoricas y practicas sobre las experiencias de juego y en la teoria fenomenologica de Alfred Schutz. Las herramientas metodologicas son: entrevistas semi estructuradas de trayectoria con jugadoras y analisis de los productos que generan a partir de sus experiencias de juego.
Evaluation of changes in pro-inflammatory cytokines in malnourished children: A Ghanaian case study

Protein-energy malnutrition (PEM) is a public health problem and is associated with high morbidity and mortality. PEM is linked with changes in biochemical and immunological parameters. This study aimed at determining the level of pro-inflammatory cytokines among healthy (control) children and those with PEM as diagnostic indicators for PEM. The study was conducted between December 2009 and June 2010 comprising a total of 115 children (35 controls and 80 malnourished children) aged between 8 – 36 months attending the Maternal and Child Health Hospital (MCHH), Kumasi. Anthropometric parameters including weight, height and mean-upper arm circumference as well as immunological and biochemical parameters (interleukin-6 (IL-6), tumour necrosis factor-alpha (TNF-α), albumin, total protein) were assessed among the studied population and the control group. After the analysis, 67.5% had marasmus, 18.8% had marasmic kwashiorkor and 13.8% had kwashiorkor. There were no statistically significant differences (p>0.05) in the mean total protein concentration of the subjects before (66.3± 1.6 g L-1) and after (69.6± 1.7 g L-1) nutritional supplement when compared to that of the controls (68.37± 1.4 g L-1) . Serum albumin concentration in the control group (43.2 ± 0.9 g L-1) was significantly higher than the concentration in the subject group before treatment (38.7 ± 0.9 g L-1, p=0.0027). The mean concentration of IL-6 in the subjects at baseline (46.1 ± 7.5 pg mL-1, p=0.0008) and after treatment (26.3 ± 5.2 pg mL-1, p=0.0148) were significantly higher than that in the control group. A 43.8% decrease in the mean concentration of IL-6 was observed after treatment. TNF-α concentration before treatment (82.1 ± 6.0 pg mL-1) was significantly higher when compared to the mean concentration in the control group (55.8 ± 2.2 pg mL-1). The study observed increases in pro-inflammatory response in malnourished children with IL-6 concentration being a significant indicator of PEM in the subjects compared to TNF- α.

DIRECTORS, AUDITORS AND SECRETARIES ROLES AND CORPORATE GOVERNANCE SYSTEM: IDENTITY THEORY PERSPECTIVES

The interest in researching corporate governance in the broader context continues unabated. The research in this area continues to be dominated by test of agency theory in advanced capitalist economies. Few researches are seen in developing countries like Nigeria. Though there have been calls for new theories to be tested in the field of corporate governance, only few have been tested, predominantly stakeholder and resource dependence theories (Barkema and Gomez-Mejia, 1998). This paper departs from previous literature in two ways. First, it tests the identity theory. Second, it uses the case study drawing empirical data from Nigeria, an emerging economy from a developing capital market to provide insights into the corporate governance mechanisms. This study explores appropriate framework and principles governing the duties and obligations of directors, auditors and secretaries. This is crucial because there is increased reliance by the stakeholders on the three actors (directors, auditors and secretaries) as it concern corporate governance both regionally and internationally. Therefore, an exploratory case study was carried out to explore the level of development of corporate governance mechanism in developing economies like Nigeria. Despite the huge challenges, issues and bottlenecks hampering good corporate governance, the study finds growth in the number of directorships, auditors and secretaries of listed companies. Also, the study reveals the code governing the responsibilities of directors; auditors and secretaries have not produced the desired result pertaining to accountability, transparency and good corporate financial reporting. Thus this adds to the body of knowledge by contributing to the corporate governance system in developing countries.
“The Reality from the Myth”: The poor as main agents of forest degradation: Lessons from Ashanti Region, Ghana

Abstract The prevailing literature on poverty-environment links mostly presents a rather deterministic view of the nexus between poverty and the environment, revolving around the negative impact of the poor on the environment. Specifically, in Ghana, empirical evidence on the prevalence of forest degradation is sparse because the requisite data are often difficult to obtain. Using a qualitative approach, data collected through in-depth interviews with 45 randomly selected participants and 5 purposively selected key informants (Traditional Authorities) and using a thematic analysis, the poverty-environment, specifically the forest degradation nexus was verified. This cross-sectional study leads the authors to posit that poverty has a minimal negative effect on major forest degradation in Ghana. The study found that the poor were rather conscious, and future-oriented with regard to the environment, specifically forests owing to how their livelihoods and survival are directly linked to their immediate environment. The results suggest that the poverty-environment nexus could be country, or context-specific and varies between geographical and historical contexts. By implication, the seemingly universal assertion that the poor are those who cause major deforestation in communities could be problematic. Henceforth, the study maintains that it would be a fallacy to make generalisations that poverty is the main cause of major forest degradation, since the link between poverty and the environment is very context-specific. We argued on the premise that reduction of poverty in Ghana may not lead to the reduction of forest degradation. Joint implementation of holistic poverty-environment strategies that incorporate both the poor and the rich should be adopted to curb the wanton forest degradation in Ghana.
Diagnosing Post Traumatic Stress Disorder: Using a Physiological Computing Method and Apparatus

Background: Post traumatic stress disorder (PTSD) is typically diagnosed using self-reports and physician interviews and observations. For example, the US military has used the Warrior Administered Retrospective Causality Assessment Tool (WARCAT), which is a self-report method for diagnostics. Methods: To help correct for associated deficiencies in self-reports, we utilized a computerized dual-task method and central nervous system (CNS) monitoring of reactions by participants who viewed troubling scenes. Results: We found evidence to support unreported PTSD reactions to these incidents. Furthermore, we used a computerized technique to induce cognitive load to distract participants from the purpose of the assessment to gain more accurate assessments. Conclusion: We conclude that using a computer apparatus is more effective in diagnosing PTSD than psychological instrumentation.
Controlling chaos in the quantum regime using adaptive measurements

The continuous monitoring of a quantum system strongly influences the emergence of chaotic dynamics near the transition from the quantum regime to the classical regime. Here we present a feedback control scheme that uses adaptive measurement techniques to control the degree of chaos in the driven-damped quantum Duffing oscillator. This control relies purely on the measurement backaction on the system, making it a uniquely quantum control, and is only possible due to the sensitivity of chaos to measurement. We quantify the effectiveness of our control by numerically computing the quantum Lyapunov exponent over a wide range of parameters. We demonstrate that adaptive measurement techniques can control the onset of chaos in the system, pushing the quantum-classical boundary further into the quantum regime.
