EUVE Investigation of Three Short-Period Binary Stars

EUVE satellite spectroscopic observations (SW, MW and LW bands covering 80 - 160, 170 - 350 and 450 A with resolutions 0.5, 1 and 2 A) and photometric observations (Deep Sky Survey, broad-band 70 - 140 A) have been obtained for two contact, 44i Boo B and VW Cep, and one detached, ER Vul, close binary stars. All three systems have orbital periods shorter than one day and thus are expected to show "saturated" levels of chromospheric, transition-region and lower-corona emissions. The spectroscopic data were of sufficient quality for an attempt at an emission-measure determination only for 44i Boo B. This determination, based entirely on iron lines, and utilizing Singular Value Decomposition formalism developed by Schmitt et al. (1996) indicates lack of any dominating temperature regime with the emission measure rising from log T about 6 to log T about 7.2. However, strong dependence of the resulting emission-measure curve on the inclusion of individual lines formed at high temperatures casts some doubts about the quality of the solution. A comparison of the line strengths have been made for selected strongest chromospheric, transition-region and lower-coronal emission lines; it included the data for the single, rapidly-rotating star AB Dor which is the only such star with the rotation period shorter than one day which has been observed with the EUVE. If the single-epoch observations are representative, the results indicate that AB Dor is under-active relative to the three binary stars which show similar levels of activity.
Overexpression of HER-2/neu oncogene and transitional cell carcinoma of bladder.

INTRODUCTION The aim of this study was to evaluate the relationship between HER-2/neu oncogene expression and grade of transitional cell carcinoma (TCC) of the bladder. MATERIALS AND METHODS In this cross-sectional study, 75 formalin-fixed paraffin-embedded specimens of primary TCC of the bladder were stained with a monoclonal antibody against HER-2/neu oncoprotein. Another section was stained by hematoxylin-eosin and the tumor grade was determined according to the World Health Organization/International Society of Urological Pathologists criteria. RESULTS Tumor specimens belonged to 49 men (65.3%) and 26 women (34.7%) with a mean age of 56.3 +/- 9.1 years (range, 39 to 80 years). The tumor grades were 1, 2, and 3 in 14 (18.7%), 35 (46.7%), and 26 (34.7%) specimens, respectively. A total of 28 (37.3%) patients were positive for overexpression of HER-2/neu. There were 1 case of HER-2/neu-positive (7.1%) with a grade 1 tumor, 10 (28.6%) with grade 2, and 17 (65.4%) with grade 3; a significant relationship between HER-2/neu overexpression and grade of the bladder TCC tumors was found (P = .002). CONCLUSION Expression of HER-2/neu oncogene has a direct relationship with the grade of the bladder TCC. Further studies with longer follow-up period and a larger sample size can determine the probable role of HER-2/neu expression as a prognostic factor in the TCC of bladder.
Learning to reproduce a sound field

The problem of sound field reproduction (SFR) in the case where the location and parameters of the primary source are known in advance has been well studied. In this paper, we tackle the problem of SFR when there is uncertainty about the location and radiation pattern of the primary source. To account for various possibilities, we sample from the collection of the likely locations and source parameters, and learn a dictionary that is able to provide a good representation of this class of sound fields. We then design loudspeaker radiation patterns to approximate the learned dictionary. Simulations show that the proposed approach offers better performance to the previously known SFR methods in cases where the location and radiation pattern of the primary source is unknown. The formulation is 2D in free space, with directional loudspeakers and pressure sampling points that correspond to omni microphones.
Case studies on the selection of useful relations in metamorphic testing

An oracle is a mechanism against which the tester can decide whether the outputs of the program for the executed test cases are correct. A fundamental problem of software testing is that, in many situations, the oracle is not availab le or too difficult to apply. A metamorphic testing(MT) method has been proposed to alleviate the oracle problem. MT is an automated testing method that employs expected properties of the target functions to test programs without human involvement. These properties are called metamorphic relations(MR). For a given problem, usually more than one MR can be identified. It is therefore intere sting and very useful for practitioners to know how to select effective MRs that are good at detecting program defects. This article proposes a guideline for the select- ion of good MRs for automated testing. The effectiveness of our strategy has been investigated through case studies.
Setting the neo-liberal agenda: How metaphors help shape socio-economic "realities"

Based on a corpus of British financial news reports, this article discusses the influence of political and socioeconomic factors on the use of metaphor in financial news discourse, seeking to establish whether neo-liberalism as a predominant economic ideology structures metaphor and whether this, in turn, is affected by events such as September 11, which changed the socio-economic setting. The approach is largely cognitive linguistic, at the same time emphasising the interactive and persuasive aspects of metaphor. Thus, metaphor is seen as a way of structuring our understanding of concepts as well as a way of interacting with the reader. In the corpus, three main metaphorical clusters are analysed. The first one presents the September-11 attacks as entities with strong impact on the economy, creating powerful allusions to war and thus setting the framework for understanding the full entailments of the other two clusters, which depict the economy as an organism and an entity/substance respectively. The latter two, it is argued, may be used to promote and support a neo-liberal agenda. Together, the three clusters provide a basis for demonstrating how metaphors may interact to create a coherent image of the economy and thus function both conceptually and interactively. Der vorliegende Beitrag untersucht anhand eines Korpus aus der britischen Wirtschaftsberichterstattung, inwiefern politische und sozio-okonomische Faktoren – wie die derzeit vorherrschende neoliberale Ideologie – Einfluss auf den Gebrauch von Metaphern in der Wirtschaftsberichterstattung haben, und ob sich diese soziookonomische Ausgangssituation durch die Geschehnisse des 11. September grundlegend veranderte. Ausgehend von einem kognitiven Metaphernbegriff werden die interaktiven, persuasiven und konzeptuellen Aspekte der Verstandnissicherung von Metaphern hervorgehoben, die anhand von drei grundlegenden metaphorischen Modellen dargestellt werden. Das erste Modell konzeptualisiert die Angriffe des 11. September als Entitaten, die einen starken Einfluss auf die Wirtschaft hatten. Wichtig sind hier die Anspielungen auf das Konzept des Krieges, mit dem zugleich die Rahmenbedingungen fur die Schaffung der beiden anderen metaphorischen Modelle DIE OKONOMIE IST EIN ORGANISMUS und DIE OKONOMIE IST EINE ENTITAT/EINE SUBSTANZ geschaffen wurden – gerade die beiden letztgenannten, so die Argumentation, begunstigten und sicherten das neoliberale Programm der folgenden Monate ab. Zusammen betrachtet liefern die drei metaphorischen Konzepte eine Basis, anhand derer dargestellt werden kann, wie durch den konzeptuellen und interaktiven Status von Metaphern ein stimmiges Bild der Wirtschaft in einem neuen Kontext entstehen kann.
A structural overview of GH61 proteins – fungal cellulose degrading polysaccharide monooxygenases

Recent years have witnessed a spurt of activities in the elucidation of the molecular function of a class of proteins with great potential in biomass degradation. GH61 proteins are of fungal origin and were originally classified in family 61 of the glycoside hydrolases. From the beginning they were strongly suspected to be involved in cellulose degradation because of their expression profiles, despite very low detectable endoglucanase activities. A major breakthrough came from structure determination of the first members, establishing the presence of a divalent metal binding site and a similarity to bacterial proteins involved in chitin degradation. A second breakthrough came from the identification of cellulase boosting activity dependent on the integrity of the metal binding site. Finally very recently GH61 proteins were demonstrated to oxidatively cleave crystalline cellulose in a Cu and reductant dependant manner. This mini-review in particular focuses on the contribution that structure elucidation has made in the understanding of GH61 molecular function and reviews the currently known structures and the challenges remaining ahead for exploiting this new class of enzymes to the full.
Thermality in de Sitter and Holography

Assuming the existence of a dS/CFT correspondence we study the holograms of sources moving along geodesics in the bulk by calculating the one point functions they induce in the boundary theory. In analogy with a similar study of uniformly accelerated sources in AdS spacetime, we argue that comoving geodesic observers correspond to a coordinate system on the boundary in which the one point function is constant. For dS3 we show that the conformal transformations on the boundary which achieve this when continued suitably to Lorentzian signature induce nontrivial Bogoliubov transformations between modes, leading to a thermal spectrum. This may be regarded as a holographic signature of thermality detected by bulk geodesic observers.
Role of Noncoding RNAs in the Regulation of P-TEFb Availability and Enzymatic Activity

P-TEFb is a transcriptional factor that specifically regulates the elongation step of RNA polymerase II-dependent transcription and its activity strictly required for Human Immunodeficiency Virus (HIV) infection and during cardiac differentiation. P-TEFb role has emerged as a crucial regulator of transcription elongation and its activity found finely tuned in vivo at transcriptional level as well as posttranscriptionally by dynamic association with different multisubunit molecular particles. Both physiological and pathological cellular signals rapidly converge on P-TEFb regulation by modifying expression and activity of the complex to allow cells to properly respond to different stimuli. In this review we will give a panoramic view on P-TEFb regulation by noncoding RNAs in both physiological and pathological conditions.
Classification of Research Citations (CRC)

Research is a continuous phenomenon. It is recursive in nature. Every research is based on some earlier research outcome. A general approach in reviewing the literature for a problem is to categorize earlier work for the same problem as positive and negative citations. In this paper, we propose a novel automated technique, which classifies whether an earlier work is cited as sentiment positive or sentiment negative. Our approach first extracted the portion of the cited text from citing paper. Using a sentiment lexicon we classify the citation as positive or negative by picking a window of at most five (5) sentences around the cited place (corpus). We have used Na\"ive-Bayes Classifier for sentiment analysis. The algorithm is evaluated on a manually annotated and class labelled collection of 150 research papers from the domain of computer science. Our preliminary results show an accuracy of 80%. We assert that our approach can be generalized to classification of scientific research papers in different disciplines.
The design, modeling and control of a tethered aerial robot for serach and rescue missions

In this paper, a new tethered aerial robot for maneuvering around the buildings for an urban search and rescue (USAR) mission is introduced. The robot can enter from a hatch in order to search the indoor area of a collapsed house or maneuver around a building for search and rescue. This new mechanism is composed of an airship as a flying and hovering platform, and a Small Aerial Vehicle (SAV) as a high maneuverable robot. A light weight tether, which is strong enough, is used to connect the airship and the SAV. The airship transports the tethered SAV (T-SAV) to the desired location, lowers it and then supports it to gather information, using his high maneuverability. In contrast to other proposed platforms, this robot operates with very low noise, making it suitable for search and rescue missions to avoid drown out victims' low voice. Moreover, the robot's actuator's vibrations are weak enough to avoid the occurrence of another collapse. This paper explains the design, modeling and controlling of the T-SAV. Finally, the first prototype of the T-SAV is explained.
Distributed visual servoing of a mobile robot for surveillance applications

A mobile robot intercepts a target identified in the image plane of a fixed camera without prior knowledge of camera viewpoint or geometry. The target may be identified manually or autonomously. When the robot moves within the camera image plane, the system develops a table of mappings between the image plane and the ground plane in which the robot moves. The robot is identified in the image plane via background subtraction and localized in the ground plane using a particle filter. This adds the potential for robotic intervention to surveillance using fixed camera systems.
Kinect sensor based physiotherapy management

In this paper, Microsoft Kinect sensor-based exercise control system for patients undergoing physiotherapy has been proposed. Exercise control system consists of two main phases including analysis of the joint orientations of patient and determination of the distribution of forces on muscle groups. Experimental results clearly show that exercise control system has been successfully managed. Besides, the proposed method can be utilized for not only exercise control system but also monitoring system.
Light-in-flight: transient imaging using photonic mixer devices

Transient imaging is a recent imaging modality in which short pulses of light are observed "in flight" as they propagate through a scene. Transient images are useful to help understand light propagation in complex environments and to analyze light transport for research and many practical applications. Two such examples are the reconstruction of occluded geometry, i.e. "looking around a corner", [Velten et al. 2012] or measuring surface reflectance [Naik et al. 2011].
Knowledge-Based Navigation of Complex Information Spaces

While the explosion of on-line information has brought new opportunities for finding and using electronic data, it has also brought to the forefront the problem of isolating useful information and making sense of large multidimension information spaces. We have built several developed an approach to building data "tour guides," called FINDME systems. These programs know enough about an information space to be able to help a user navigate through it. The user not only comes away with items of useful information but also insights into the structure of the information space itself. In these systems, we have combined ideas of instance-based browsing, structuring retrieval around the critiquing of previously-retrieved examples, and retrieval strategies, knowledge-based heuristics for finding relevant information. We illustrate these techniques with several examples, concentrating especially on the RENTME system, a FINDME system for helping users find suitable rental apartments in the Chicago metropolitan area.
Caracterização das lesões desportivas em atletas de Tênis de Mesa

Introduction: The table tennis is characterized by requiring of the athletes intense body movement. The gestures performed by athletes require continuous postural changes, in cases of any sway in body structures may produce pos- tural changes or initiate processes of injuries. Objective: The aim of this study was to characterize the table tennis le- sions. Method: Were evaluated 31 athletes (26 males and fi ve females) with mean age 22.35±6.67 years. The sub- jects were interviewed with the Reported Morbidity Inquires retroactive to the 2009 season. It was used techniques of descriptive and analytical statistics. Results: The largest number of injuries was muscular (74.35%), on the shoulder (43.58%) during the movement of top spin (33.33%) in the specifi c training phase (64.1%) with symptomatic return to the activities (69.23%). Conclusion: The weekly training workload infl uences the number of lesions.
Cross-lingual Word Sense Disambiguation for Predicate Labelling of French

We address the problem of transferring semantic annotations, more specifically predicate labellings, from one language to another using parallel corpora. Previous work has transferred these annotations directly at the token level, leading to low recall. We present a global approach to annotation transfer that aggregates information across the whole parallel corpus. We show that this global method outperforms previous results in terms of recall without sacrificing precision too much. Mots-cles : transfert inter-langue, annotation semantique automatique, predicats, desambiguisation lexicale, cor- pus paralleles.
Joint source-channel mappings for the relay channel

The three-node relay channel with a Gaussian source is studied for transmission subject to a low-delay constraint. A joint source-channel coding design algorithm is proposed and numerically evaluated. The designed system is compared to a reference system, based on modular source and channel coding, and the distortion-rate function for the Gaussian source, using known achievable rates on the relay channel. The structure of the source encoder and the relay mapping is visualized and discussed in order to gain understanding of how the system works. The relay mapping gets a structure that resembles a Wyner-Ziv code.
Binary Tomography Reconstruction Algorithm Based on the Spectral Projected Gradient Optimization

In this paper we propose an optimization approach based on the Spectral Projected Gradient (SPG) method for solving the binary tomography reconstruction problem. Using a convex-concave regularization we treat the reconstruction problem as a convex and box constrained optimization problem which is suitable to solve by SPG method. Experimental results on the limited set of test problems show that the new method has competitive reconstruction performance in comparison with a well known non-deterministic simulated annealing approach. In addition, its capability to apply other regularization terms gives to this deterministic method a desirable
A control flow obfuscation method for Android applications

With the rapid development of mobile Internet, the number of mobile applications has increased rapidly. How to protect the copyright of mobile applications is one of the most critical issues in nowadays. Software control flow obfuscation is a wildly used technique to protect the copyright of the software. In this paper, we proposed a control flow obfuscation method for Android applications. The proposed method combines and improves inserting redundant control flow and flattening control flow obfuscation, and further strengthen the strength of obfuscation by building control access policy. Experimental results indicate that the algorithm performs well against automated attacks.
The Cog-4 Subset of the National Institutes of Health Stroke Scale as a Measure of Cognition: Relationship with Baseline Factors and Functional Outcome after Stroke Using Data from the Virtual International Stroke Trials Archive

Background. Assessing poststroke cognitive impairment is complex. A subscale of the NIHSS, the Cog-4, has been proposed as a quick test of “cognitive impairment. ” but a study of its properties in a larger dataset is lacking. Methods. Data from 9,147 patients with acute stroke from the VISTA archive was used to generate Cog-4 scores. The statistical properties of Cog-4, its relationship with baseline clinical characteristics, and other functional outcome measures at day 90 were assessed. Results. Mean age of patients was 69.2 years and 45.8%, were females. Day-90 Cog-4 was highly positively skewed (skewness 0.926). Patients with left hemispheric stroke had higher day-90 Cog-4 score (P < 0.001). Age, stroke severity, and previous stroke were significant predictors of Cog-4. Cog-4 was significantly correlated with dependency (modified Rankin Scale, r s = 0.512), and disability (Barthel Index, r s = −0.493). Conclusions. The Cog-4 scale at day 90 cannot be considered a useful test of cognition since it only superficially measures cognition. It is heavily dependent on the side of stroke, is inevitably associated with functional outcome (being a subset of the NIHSS), and suffers from a profound “floor” effect. Specific and validated measures are more appropriate for the assessment of poststroke cognition than Cog-4.
Reduction of lesion in injured rat spinal cord and partial functional recovery of motility after bone marrow derived mesenchymal stem cell transplantation.

AIM This study aimed to analyze the effect of rat bone marrow-mesenchymal stem cells (rBM-MSCs) delivery on lesion site after spinal cord injury, and to observe the functional recovery after transplantation. MATERIAL AND METHODS MSCs were isolated from rat femurs and tibias. The experimental rat population was divided into four groups: only laminectomy (1); laminectomy+trauma (2); laminectomy+trauma+PBS (3); laminectomy+trauma+MSCs (4). Their motility were scored regularly. After 4-weeks, rats were sacrificed, and their spinal cords were examined for GFP labeled rBM-MSCs by immunostainings. RESULTS In the early posttraumatic period, the ultrastructures of spinal cord tissue were preserved in Group 4. The majority of cells forming the ependymal region around the central canal were found to be MSCs. The gray-and-white-matter around the ependymal region were composed of Nestin+/GFAP+ cells, with astrocytic-like appearance. The scores showed significant motor recovery in Group 4, especially in hind limb functions. However, no obvious change was observed in other groups. CONCLUSION The increase Nestin+/GFAP+ cells in the gray-and-white-matter around the ependymal region could indicate the potential to self-renew and plasticity. Thus, transplantation of rBM-MSCs might be an effective strategy to improve functional recovery following spinal cord trauma. In conclusion, molecular factors in cell fate decisions could be manipulated to enhance reparative potential of cell-based therapy.
