Test Case Selection for Data Flow Based Regression Testing of BPEL Composite Services

BPEL(Business Process Execution Language) composite service evolves a lot in its lifetime. Regression testing must be performed to ensure the correctness of each evolved version. In this article, an approach is proposed to select test cases for regression testing based on data flow testing criterion. With XCFG(eXtended Control Flow Graph) modeling BPEL composite service, the approach improves the traditional data flow analysis to compute the def-use pairs in BPEL process, and then identifies the affected def-use pairs by comparing the def-use pairs and XCFG model in the evolved version with those in the baseline version, where related WSDL(Web Service Description Language) documents are incorporated for comparison. The data flow paths covering the affected def-use pairs are calculated for regression testing, and some of them can reuse the test cases in the baseline version, which are determined by analyzing the path condition of data flow paths between two versions. The proposed approach can detect three kinds of changes, including process change, binding change and interface change. Experimental study shows the effectiveness.
THE POPULAR IN THE POLITICAL SYSTEM

This paper suggests a systems theoretical re-reading of popular communication and the Popular in the political system. Luhmann' anti-humanist notion of communication helps to reframe the discussion of the Popular: it is not defined by an en- or decoding instance, but by a particular mode of ‘connectivity'. Drawing from heterogeneous material (Mars Attacks! , crowd psychology, theory of democracy), it is argued that the problem of the Popular arises when a functional system has to represent something that transgresses the system' universality. That which the system has to exclude to become a system re-emerges as ‘grotesque hybrid’, thus pointing at a universality that is, on the one hand, an opportunity for a further universalization and, on the other, a threat to the very universality of the system. The ‘Popular’ thus acquires a hybrid position by articulating these two dimensions.
Online Reference Limitation Method of Shunt-Connected Converters to the Grid to Avoid Exceeding Voltage and Current Limits Under Unbalanced Operation—Part I: Theory

This paper focuses the analysis around a grid-connected converter that operates under unbalanced voltage and current conditions. Two different scenarios have been selected to validate the proposed algorithms. In the first scenario, the converter operates as a reactive power compensator, exchanging reactive power with the grid, and minimizing the dc bus voltage oscillations. The second scenario is more challenging, since it operates as a load balancer. In this application, the unbalanced current consumption of the load is compensated by the converter, exchanging positive and negative sequence currents with the grid. Another objective in this second scenario is to compensate the reactive power of the unbalanced load. It is important to highlight that in both scenarios, any maximum limit of the converter can be exceeded due to the specific unbalanced voltage and current conditions. Three variables are considered critical for the converter: 1) output ac current limit; 2) output ac voltage limit; and 3) dc bus voltage oscillation limit. Thus, this paper proposes a control method, which limits online the reactive power reference in the first scenario and the exchanged current references in the second scenario in order not to exceed any of the mentioned critical variables. The corresponding experimental results are shown in Part II of this paper so as to validate the limitation algorithm obtained by means of the mathematical analysis carried out in Part I.
Drama, Desire and Schooling. Drives to learning in creative and expressive school subjects

Desire is an unfamiliar and neglected concept in education and schooling. This paper makes an argument for the need to consider desire as a drive to learning in schools. In parallel with both Freud and Piaget, Vygotsky draws connections between play in children, fantasy and imagination in adolescence and, in adulthood, the making and enjoyment of the arts. In each case, the force, or drive towards creativity is seen as an expression of desire. With the emergence of arts-oriented subjects in the curricula of mass schooling, adolescents are encouraged to draw resources from the internalised worlds of fantasy and imagination and to materialise these in the social production of various cultural forms, where the resources of production are held as much between the group of students as within their individual and internal worlds of fantasy and imagination. This paper focuses particularly on the secondary school curriculum, taking a piece of improvised drama as evidence and analysing it from a Vygotskian perspective. Firstly, how, in these kinds of activity, might educationalists gain insights into the individual and social drives towards learning and development and, secondly, what resources from the socio-cultural environment are utilised and transformed? Major themes to emerge will be the productive and dynamic set of tensions which are exposed between the desire of the individual and the processes of social production, between the drive of desire and structuring principles of particular cultural forms and, finally, between the force of desire and the institutional constraints of schooling.
Mitochondrial Reactive Oxygen Species Mediate Lysophosphatidylcholine-Induced Endothelial Cell Activation

Objective— Hyperlipidemia-induced endothelial cell (EC) activation is considered as an initial event responsible for monocyte recruitment in atherogenesis. However, it remains poorly defined what is the mechanism underlying hyperlipidemia-induced EC activation. Here, we tested a novel hypothesis that mitochondrial reactive oxygen species (mtROS) serve as signaling mediators for EC activation in early atherosclerosis. Approach and Results— Metabolomics and transcriptomics analyses revealed that several lysophosphatidylcholine (LPC) species, such as 16:0, 18:0, and 18:1, and their processing enzymes, including Pla2g7 and Pla2g4c, were significantly induced in the aortas of apolipoprotein E knockout mice during early atherosclerosis. Using electron spin resonance and flow cytometry, we found that LPC 16:0, 18:0, and 18:1 induced mtROS in primary human aortic ECs, independently of the activities of nicotinamide adenine dinucleotide phosphate oxidase. Mechanistically, using confocal microscopy and Seahorse XF mitochondrial analyzer, we showed that LPC induced mtROS via unique calcium entry–mediated increase of proton leak and mitochondrial O2 reduction. In addition, we found that mtROS contributed to LPC-induced EC activation by regulating nuclear binding of activator protein-1 and inducing intercellular adhesion molecule-1 gene expression in vitro. Furthermore, we showed that mtROS inhibitor MitoTEMPO suppressed EC activation and aortic monocyte recruitment in apolipoprotein E knockout mice using intravital microscopy and flow cytometry methods. Conclusions— ATP synthesis–uncoupled, but proton leak-coupled, mtROS increase mediates LPC-induced EC activation during early atherosclerosis. These results indicate that mitochondrial antioxidants are promising therapies for vascular inflammation and cardiovascular diseases.
Automatic relational scene representation for safe robotic manipulation tasks

In this paper, we propose a new approach for automatically building symbolic relational descriptions of static configurations of objects to be manipulated by a robotic system. The main goal of our work is to provide advanced cognitive abilities for such robotic systems to make them more aware of the outcome of their actions. We describe how such symbolic relations are automatically extracted for configurations of box-shaped objects using notions from geometry and static equilibrium in classical mechanics. We also present extensive simulation results as well as some real-world experiments aimed at verifying the output of the proposed approach.
Hand gesture interaction using color-based method for tabletop interfaces

In this paper, a hand gesture recognition method based on color marker detection is presented, In this case, we have used four types of colored markers (red, blue, yellow and green) mounted on the two hands. With this posture the user can perform different gestures as zoom, move, draw, and write on a virtual keyboard. This implemented system provides more flexible, natural and intuitive interaction possibilities, and also offers an economic and practical way of interaction.
WEBCON: a toolkit for an automatic, data dictionary based connection of databases to the WWW

Despite the availability of various tools for creating dynaniic HTML pages, the development of database applications in the World Wide Web is still relatively costly. Many dynamic HTML pages are needed for making a database comprehensively accessible via the web. This paper presents a toolkit for connecting existing relational databases to the web without having to write code in HTML or any other language. It makes extensive use of the database's dictionary and of additional meta information, which can easily be defined with a web based maintenance tool. The meta schema used will be discussed in detail. It allows to control layout and content of the pages for querying and populating the database and to define arbitrary joins within the database. The corresponding queries are created automatically.
Extension, subversion, containment: eco‐nationalism and (post)colonial nature in Aotearoa New Zealand

National identity in many post-colonial states is predicated on nature being outside and antecedent to culture and the colonial project. This paper questions the historical and essentialist assumptions underpinning this vision using New Zealand as a case study, and in particular the Christchurch Botanic Gardens in the nineteenth century. I argue that the Gardens were a site in the multi-species extension of colonial space, but that far from being docile entities, non-humans kicked back to change the very nature of the project. New Zealand's eco-nationalist project is described as not only an attempt to order the past, present and future lives of non-humans (invasive, native and migrant alike), but also to sanitise the colonial expropriation of the indigenous and to preclude any mode of relating to ‘nature’ that might subvert the essentialisms inherent in a preservationist ethic. Situated between three modes of critique: nature-as-ideology; nature as complex but real; and an ontological exposure of hidden hybridity, I make a modest move beyond (re)description of naturecultures to normative critique of their constitutive relations.
Loss of independence in early Parkinson disease

Objective: To determine the risk, predictors, and prognosis of independence loss and institutionalization in patients with early Parkinson disease (PD). Methods: We conducted a prospective population-based 5-year longitudinal study following 189 patients with incident PD and 174 controls matched for age, sex, and comorbidity. Health care status was assessed repeatedly with standardized interviews. Results: More newly diagnosed patients with PD (15.9%) than controls (5.7%) were dependent in activities of daily living at baseline (relative risk [RR] 2.8, p = 0.004). During follow-up, 40.9% of the initially independent patients lost their independence vs 9.1% of controls (RR 4.5, p < 0.001). Higher age, shorter symptom duration, increasing motor severity, and presence of mild cognitive impairment at PD diagnosis independently predicted independence loss during follow-up. Dependency was irreversible in most (>95%) patients. Long-term care facility placement was needed in 8.8% of patients vs 0.6% of controls (RR 15.4, p = 0.001). More patients with PD admitted to long-term care facilities were fallers (RR 4.8, p < 0.001), had hallucinations (RR 4.4, p = 0.001), or had dementia (RR 4.2, p < 0.001) than home-dwelling patients. Once admitted to a long-term care facility, the age-adjusted RR for death during the study period was 5.5 (p = 0.002) vs patients never admitted and 25.1 (p < 0.001) vs controls. Conclusions: Patients with early PD face a substantially greater risk of independence loss and institutionalization than well-matched controls. Independence loss is irreversible in most patients and represents a sinister prognostic factor in early PD. These findings have implications for patient management and health care planning.
Improving Accuracy and Interpretability of Clinical Decision Support Systems through Possibilistic Constrained Evolutionary Optimization

In this paper we propose a computable approach to represent medical rules by means of Fuzzy Clinical Decision Support Systems by preserving both accuracy and interpretability. Usually, prediction accuracy of these systems goes to overlook their linguistic interpretability and, in order to simultaneously optimize those conflicting properties, multi-objective evolutionary algorithms are adopted. Differently, our proposal relies on the alternative assumption that the interpretability-accuracy tradeoff problem can be approached as a single-objective constrained optimization problem. In this spirit, a Differential Evolution algorithm, with a selection operator suitably adapted to the aim, is used for membership function tuning by maximizing accuracy and fulfilling several constraints for linguistic distinguish ability degrees - a semantic property of fuzzy sets with notable relevance for interpretability of fuzzy models - evaluated through Possibility measure. The proposed approach has been tested on the Vertebral Column Data set, a recent medical database publicly available, with results that confirm the effectiveness of our method.
Second-order statistics based prefilter-blind equalization for MIMO-OFDM

In this paper, a SOS-based prefilter-blind equalizer for MIMO-OFDM system which can equalize FIR-MIMO channel at the receiver is proposed. The proposed scheme uses a set of orthogonal prefilters at the transmitter such that the transmitted signal can be colored temporally thereby satisfying the identifiability condition previously proposed by Hua and Tugnait. The scheme is shown to outperform previously proposed schemes in terms of BER and computational complexity. Simulation results have shown that the BER performance is close to that of a least-squares zero-forcing equalizer with perfect channel knowledge.
Novel Dominant Rhodopsin Mutation Triggers Two Mechanisms of Retinal Degeneration and Photoreceptor Desensitization

A variety of rod opsin mutations result in autosomal dominant retinitis pigmentosa and congenital night blindness in humans. One subset of these mutations encodes constitutively active forms of the rod opsin protein. Some of these dominant rod opsin mutant proteins, which desensitize transgenic Xenopus rods, provide an animal model for congenital night blindness. In a genetic screen to identify retinal degeneration mutants in Drosophila, we identified a dominant mutation in the ninaE gene (NinaEpp100) that encodes the rhodopsin that is expressed in photoreceptors R1-R6. Deep pseudopupil analysis and histology showed that the degeneration was attributable to a light-independent apoptosis. Whole-cell recordings revealed that the NinaEpp100 mutant photoreceptor cells were strongly desensitized, which partially masked their constitutive activity. This desensitization primarily resulted from both the persistent binding of arrestin (ARR2) to the NINAEpp100 mutant opsin and the constitutive activity of the phototransduction cascade. Whereas mutations in several Drosophila genes other than ninaE were shown to induce photoreceptor cell apoptosis by stabilizing a rhodopsin-arrestin complex, NinaEpp100 represented the first rhodopsin mutation that stabilized this protein complex. Additionally, the NinaEpp100 mutation led to elevated levels of Gqα in the cytosol, which mediated a novel retinal degeneration pathway. Eliminating both Gqα and arrestin completely rescued the NinaEpp100-dependent photoreceptor cell death, which indicated that the degeneration is entirely dependent on both Gqα and arrestin. Such a combination of multiple pathological pathways resulting from a single mutation may underlie several dominant retinal diseases in humans.
3D Liver Tumor Segmentation in CT Images Using Improved Fuzzy C-Means and Graph Cuts

Three-dimensional (3D) liver tumor segmentation from Computed Tomography (CT) images is a prerequisite for computer-aided diagnosis, treatment planning, and monitoring of liver cancer. Despite many years of research, 3D liver tumor segmentation remains a challenging task. In this paper, an efficient semiautomatic method was proposed for liver tumor segmentation in CT volumes based on improved fuzzy C-means (FCM) and graph cuts. With a single seed point, the tumor volume of interest (VOI) was extracted using confidence connected region growing algorithm to reduce computational cost. Then, initial foreground/background regions were labeled automatically, and a kernelized FCM with spatial information was incorporated in graph cuts segmentation to increase segmentation accuracy. The proposed method was evaluated on the public clinical dataset (3Dircadb), which included 15 CT volumes consisting of various sizes of liver tumors. We achieved an average volumetric overlap error (VOE) of 29.04% and Dice similarity coefficient (DICE) of 0.83, with an average processing time of 45 s per tumor. The experimental results showed that the proposed method was accurate for 3D liver tumor segmentation with a reduction of processing time.
How Culture Constructs Our Sense of Neighborhood: Mental Maps and Children's Perceptions of Place

Abstract This research examines the effects of culture on a child's perceptions of his or her neighborhood by comparing the neighborhood sketch maps of a group of Amish and non-Amish children from the same rural Pennsylvania neighborhood. The results of this study lend credence to the belief that early and intensive acculturation helps define our sense of “neighborhood” very early in life. There are possible applications to multicultural education in this study. As we discover what is important to students from other subcultures and backgrounds, we can customize our instruction to make it more meaningful and effective.
The Evolution of Business Networks along Innovation Lifetime cycle: a Longitudinal Study

In the last years many studies evidenced the contribution of networks in innovation, especially in terms of knowledge creation. Moreover recent studies analyzed deeper the features assumed by the innovation network, trying to understand which are the features of the network contributing to create innovation. Even if the literature about innovation network seems to focus in particular on the role of the network in generating a new idea, no many studies analyze the evolution of the network in the following steps of the innovation lifetime cycle. In particular, there are no many studies explaining how the companies strategies within the network can influence the evolution of innovation along its lifetime cycle. So, the aim of this paper is to analyze – using a longitudinal case study – how the strategies adopted by the actors involved in the network, in particular their goals, influence the evolution of innovation during the different steps of its lifetime cycle. The longitudinal case study reported in this paper refers to a mechanical company operating in the knitting machineries industry. This company, about ten years ago, launched on the market a new technology, which enabled to create the so-defined “seamless” clothes. The creation of this new technology was thanks to a network. The evolution of the innovations launched by the company along the time reveals that innovation is strictly related to the features of the actors belonging the network and in particular to their strategies, that changed over the time.
Separation of Reflection Components by Kernel Independent Component Analysis

Summary When we view a scene through transparent glass, the image is a linear superposition of two images, a real image observed through a glass and a virtual image reflected on it. We can separate the reflections by a polarization and Independent Component Analysis (ICA). Since the image observed through digital camera is non-linearly transformed by gamma correction etc, it may cause error in image processing for image analysis and measurement. The kernel-based methods are effective for such non-linearity. In this paper, we remove the reflections by using Kernel Independent Component Analysis (KICA) and show that KICA is more effective than ICA even if the observed image is non-linearly transformed by camera.
RhoA is down-regulated at cell–cell contacts via p190RhoGAP-B in response to tensional homeostasis

p190RhoGAP-B mediates Rho activity and ductal morphogenesis in response to 3D collagen stiffness. p190B associates with p120-catenin at cell–cell contacts, where RhoA activity is decreased compared to cell–ECM adhesions. This suggests that Rho is in an inactive pool at cell–cell contacts and is recruited to cell–ECM contacts in stiff matrices.
Syndromes of Insulin Resistance in the Rat: Inducement by Diet and Amelioration with Benfluorex

Insulin resistance, mainly in skeletal muscle, is linked to a cluster of prevalent diseases including NIDDM, dyslipidemias, hypertension, and cardiovascular disease. To determine if an oversupply of lipid is associated with the development of skeletal muscle insulin resistance, we examined the effect of the hypolipidemic agent benfluorex in dietary models of insulin resistance. Adult, male Wistar rats were divided into six groups and maintained for 4 wk on diets high in complex carbohydrate, fructose or fat, with or without 50 mg · kg−1 · day−1 of benfluorex, given orally. Insulin action was assessed using a hyperinsulinemic (∼ 100 mU/L) euglycemic clamp, with 2-deoxyglucose tracer for individual tissue evaluation, in chronically cannulated conscious animals. Compared with starch feeding, fructose and fat feeding significantly impaired insulin action at the whole-body level (–46% and –41%, respectively, both P < 0.001), as well as in individual skeletal muscles. Fructose feeding increased circulating TGs (by 80%, P < 0.01) but not skeletal muscle TGs; whereas, fat feeding increased skeletal muscle TGs (by 59%, P < 0.01) but not circulating TGs. With benfluorex, however, diet had no effect on circulating and storage TGs; and development of skeletal muscle insulin resistance in the two diet groups was prevented. Feeding fructose but not fat significantly increased mean arterial BP (by 13%, P < 0.05), an effect prevented by benfluorex. These effects support the hypothesis that the development of muscle insulin resistance in these models is linked to local or systemic oversupply of lipid. These diet models—and the parallel effect of benfluorex on insulin resistance, lipids, and hypertension—may prove useful in the search for the mechanisms that underlie the human disorders associated with insulin resistance.
