Combination of CDF and D0 measurements of the W boson helicity in top quark decays

We report the combination of recent measurements of the helicity of the W boson from top quark decay by the CDF and D0 collaborations, based on data samples corresponding to integrated luminosities of 2.7 - 5.4 fb^-1 of ppbar collisions collected during Run II of the Fermilab Tevatron Collider. Combining measurements that simultaneously determine the fractions of W bosons with longitudinal (f0) and right-handed (f+) helicities, we find f0 = 0.722 \pm 0.081 [\pm 0.062 (stat.) \pm 0.052 (syst.)] and f+ = -0.033 \pm 0.046 [\pm 0.034 (stat.) \pm 0.031 (syst.)]. Combining measurements where one of the helicity fractions is fixed to the value expected in the standard model, we find f0 = 0.682 \pm 0.057 [\pm 0.035 (stat.) \pm 0.046 (syst.)] and f+ = -0.015\pm0.035 [\pm 0.018 (stat.) \pm 0.030 (syst.)]. The results are consistent with standard model expectations.
Toward a Smart Sustainable Development of Port Cities/Areas: The Role of the “Historic Urban Landscape” Approach

After the 2008 crisis, smart sustainable development of port areas/cities should be developed on the basis of specific principles: the synergy principle (between different actors/systems, in particular the socio-cultural and economic system), the creativity principle and the circularization principle. The Historic Urban landscape (HUL) approach becomes the guarantee that the transition toward the smart city development model is based on specific local cultural resources, and not only on technological innovations. In other words, the eco-town/eco-city strategy becomes culture-led. It stimulates places as spatial “loci” for implementing synergies and circularization processes. Without new evaluation tools and a widespread “evaluation culture” the risks in implementing HUL are very high.
The Interleukin-8 Pathway in Cancer

Interleukin-8 (IL-8) is a proinflammatory CXC chemokine associated with the promotion of neutrophil chemotaxis and degranulation. This chemokine activates multiple intracellular signaling pathways downstream of two cell-surface, G protein–coupled receptors (CXCR1 and CXCR2). Increased expression of IL-8 and/or its receptors has been characterized in cancer cells, endothelial cells, infiltrating neutrophils, and tumor-associated macrophages, suggesting that IL-8 may function as a significant regulatory factor within the tumor microenvironment. The induction of IL-8 signaling activates multiple upstream signaling pathways that (a) impinge on gene expression via regulation of numerous transcription factor activities, (b) modulate the cellular proteome at the level of translation, and/or (c) effect the organization of the cell cytoskeleton through posttranslational regulation of regulatory proteins. As a consequence of the diversity of effectors and downstream targets, IL-8 signaling promotes angiogenic responses in endothelial cells, increases proliferation and survival of endothelial and cancer cells, and potentiates the migration of cancer cells, endothelial cells, and infiltrating neutrophils at the tumor site. Accordingly, IL-8 expression correlates with the angiogenesis, tumorigenicity, and metastasis of tumors in numerous xenograft and orthotopic in vivo models. Recently, IL-8 signaling has been implicated in regulating the transcriptional activity of the androgen receptor, underpinning the transition to an androgen-independent proliferation of prostate cancer cells. In addition, stress and drug-induced IL-8 signaling has been shown to confer chemotherapeutic resistance in cancer cells. Therefore, inhibiting the effects of IL-8 signaling may be a significant therapeutic intervention in targeting the tumor microenvironment.
Graphical modelling for multivariate time series

Graphical models for multivariate time series is a concept extended by Dahlhaus (2000) from a random vector to a time series. We propose a test statistic to identify a graphical model for multivariate time series with the Kullback-Leibler distance between two spectral density matrices characterized by graphical models. Asymptotic null distribution is derived to be normal with the mean and variance which depend just on the dimensions of the graphs, which makes the modelling procedure easy and practical.
Predicting Aboveground Biomass in Second Growth Coast Redwood: Comparing Localized with Generic Allometric Models

Biomass amounts predicted by generalized models are often not applicable for small regions. Localized allometric models were developed relating tree/biomass components to diameter at breast height (dbh) for coast redwood (Sequoia sempervirens (D. Don) Endl. ) from an industrial timberland in northwestern California, USA. dbh for the candidate trees ranged from 2.54 cm to 84.07 cm. Biomass of tree components, such as bole, foliage, bark, live and dead branches, along with the total aboveground biomass (TAGB) were estimated. Other tree dimensions such as tree height, height to live crown, weight and volume of bole wood were also modeled. Localized allometric models were able to explain more than 93% of the variability for most of the tree components (p < 0.001). Biomass amounts predicted from the widely used generalized models were different from that estimated by the localized allometric model developed from this study. However, the results presented in this study should be used carefully to predict the biomass components, if applied outside the stated dbh range or stand conditions on which this study was based.
SKIN ULCER IMAGE SEGMENTATION BASED ON GROW CUT METHOD

In this specific paper, we have suggested an algorithm for synergistic segmentation of skin ulcer images of the diseased. If a small number of user pixels are provided, then by using Grow Cut method, we can automatically segment the rest of the images. User can sharply observe the segmentation procedure and guide the algorithm whenever the segmentation becomes difficult. In particular areas, where the segmentation is done automatically, no extra effort by the user is necessitated. The segmented skin ulcer images are presented.
Process and Formulation Variables Affecting the Performance of a Rupturable Capsule‐Based Drug Delivery System with Pulsatile Drug Release

The objective of this study was to optimize several process and formulation parameters, which influence the performance of a rupturable, pulsatile drug delivery system. The system consisted of a drug‐containing hard gelatin capsule, a swelling layer of croscarmellose (Ac‐Di‐Sol®) and a binder, and an outer ethylcellulose coating. Polyvinyl pyrrolidone (Kollidon 90F) was superior to HPMC and HPC as a binder for the swelling layer with regard to binding (adherence to capsule) and disintegration properties of the swelling layer. The capsule‐to‐capsule uniformity in the amount of swelling layer and outer ethylcellulose coating, which significantly affected the lag time prior to rupture of the capsule, was optimized by decreasing the batch size, and by increasing the rotational pan speed and the distance between the spray nozzle and the product bed. The type of baffles used in the coating pan also affected the layering uniformity. Fully‐filled hard gelatin capsules had a shorter lag time with a higher reproducibility compared to only half‐filled capsules, because the swelling pressure was directed primarily to the outer ethylcellulose coating and not to the inner capsule core. Stability studies revealed that the lag time of the capsules was stable over a 240‐day period when the moisture content was kept unchanged.
A Memory-Based Theory of Verbal Cognition

The syntagmatic paradigmatic model is a distributed, memory-based account of verbal processing. Built on a Bayesian interpretation of string edit theory, it characterizes the control of verbal cognition as the retrieval of sets of syntagmatic and paradigmatic constraints from sequential and relational long-term memory and the resolution of these constraints in working memory. Lexical information is extracted directly from text using a version of the expectation maximization algorithm. In this article, the model is described and then illustrated on a number of phenomena, including sentence processing, semantic categorization and rating, short-term serial recall, and analogical and logical inference. Subsequently, the model is used to answer questions about a corpus of tennis news articles taken from the Internet. The model's success demonstrates that it is possible to extract propositional information from naturally occurring text without employing a grammar, defining a set of heuristics, or specifying a priori a set of semantic roles.
A Prediction Model for Software Performance in Symmetric Multiprocessing Environments

The broad introduction of multi-core processors made symmetric multiprocessing (SMP) environments mainstream. The additional cores can significantly increase software performance. However, their actual benefit depends on the operating system scheduler's capabilities, the system's workload, and the software's degree of concurrency. The load distribution on the available processors (or cores) strongly influences response times and throughput of software applications. Hence, understanding the operating system scheduler's influence on performance and scalability is essential for the accurate prediction of software performance (response time, throughput, and resource utilisation). Existing prediction approaches tend to approximate the influence of operating system schedulers by abstract policies such as processor sharing and its more sophisticated extensions. However, these abstractions often fail to accurately capture software performance in SMP environments. In this paper, we present a performance Model for general-purpose Operating System Schedulers (MOSS). It allows analyses of software performance taking the influences of schedulers in SMP environments into account. The model is defined in terms of timed Coloured Petri Nets and predicts the effect of different operating system schedulers (e.g., Windows 7, Vista, Server 2003, and Linux 2.6) on software performance. We validated the prediction accuracy of MOSS in a case study using a business information system. In our experiments, the deviation of predictions and measurements was below 10% in most cases and did not exceed 30%.
Phytotoxic activity of foliar volatiles and essential oils of Calamintha nepeta (L.) Savi

Foliar volatiles and essential oils of Calamintha nepeta (L.) Savi, a Mediterranean plant species belonging to the Labiatae family, were investigated for their phytotoxic activities on seed germination and root growth of crops (Lactuca sativa L. and Raphanus sativus L.) and weed species (Lolium perenne L. and Amaranthus retroflexus L.). Foliar volatiles of C. nepeta (L.) Savi strongly inhibited both germination and root growth of lettuce, and its essential oils, especially at 125, 250 and 500 μL/L, inhibited both processes in lettuce, radish and A. retroflexus L. species, while displaying a little effect on L. perenne L. By GC–MS, 28 chemicals were identified: 17 monoterpenes, 8 sesquiterpenes, 1 diterpene and 2 miscellaneous. Pulegone was the main constituent of the C. nepeta (L.) Savi essential oils. The terpenic components of essentials oils were probably responsible for the phytotoxic activities.
[Parakinesia brachialis oscitans].

INTRODUCTION In some cases of hemiplegia the onset of yawning is associated with an involuntary raising of the paralyzed arm. PATIENTS AND METHOD Four observations of this movement, which is seldom described probably because it is mostly neglected, were made in the neurology unit of the University Hospital of Poitiers. The descriptions were compared with other cases that have been published in the medical literature of the last 150 years. Cerebral imagery shows a lesion that is most often localized on the internal capsule. After comparison with experimental models in cats, it is proposed that the section of the cortico-neocerebellum tract of the extra-pyramidal system disinhibits the spino-archeocerebellum tract, enabling a motor stimulation of the arm by the lateral reticular nucleus, which harmonises central respiratory and locomotor rhythms. RESULTS AND CONCLUSION Some subcortical structures, that are phylogenetically more ancient, thus disinhibit regained autonomy in the homeostasis process associating the massive inspiration of yawning--a form of reflex behavior that stimulates vigilance--with a motor control that is active during locomotion. For this phenomenon we coined the term "parakinesia brachialis oscitans".
The relational selves of female graduate students during academic mentoring: from dialogue to transformation

This study, framed by social constructionism, retrospectively examines how faculty mentoring influenced the transformations of 10 female graduate students’ relational selves and their professional identities as qualitative researchers and scholars. Participants reported that effective mentorships often resulted in collaboration on research projects, as well as shared decision‐ and meaning‐making. Effective mentoring also led to the development of the students’ research skills while simultaneously constructing their professional and academic selves. These situated mentorships were shaped by the diverse values, expectations, and hopes that the participants associated with mentoring. Additionally, the local practices, power structures, and relationships at the department or university level influenced, and possibly discouraged, active communication and ongoing dialogue regarding the individuals’ experience of mentoring. Ultimately, participants described how their experiences of mentoring welcomed them into the scholarly community and ensured their professional competence as researchers and academics, which, in turn, transformed the students’ broader sense of self.
Software-based resolver-to-digital conversion and online fault compensation

A simple and cost-effective software-based resolver to digital converter together with a permanent magnet synchronous motor control system were presented. The proposed method incorporates software generation of the resolver carrier and using anti-tangent calculation for synchronous demodulation of the resolver outputs signal in such a way that there is a substantial savings on hardware like the costly carrier oscillator and associated digital and analog circuits for amplitude demodulators. And the faults of amplitude imbalance and imperfect quadrature of resolver signal can also be detected and compensated by software online. Computer simulation results demonstrate the effectiveness and applicability of the proposed scheme.
I 4-D 8 Declarative Semantics and Query Core for the Xcerpt Query Language

is article introduces a preliminary declarative semantics for a subset of the language Xcerpt (so-called grouping-strati able programs) in form of a classical (Tarski style) model theory, adapted to the speci c requirements of Xcerpt’s constructs (e.g. the various aspects of incompleteness in query terms, grouping constructs in rule heads, etc.). Most importantly, the model theory uses term simulation as a replacement for term equality to handle incomplete term speci cations, and an extended notion of substitutions in order to properly convey the semantics of grouping constructs. Based upon this model theory, a xpoint semantics is also described, leading to a rst notion of forward chaining evaluation of Xcerpt programs. In a second part of this deliverable, syntax, semantics, complexity, and evaluation for the query core of Xcerpt (and many other Web query languages such as XQuery and SPARQL) is introduced and discussed.

Communication, Community Attachment, and Involvement

A long tradition of social theory has emphasized the importance of communication to individuals' ties to their communities. Two major types of such ties are treated here: affective attachment and cognitive and active involvement. Data from a sample survey of 400 adult residents of Iowa are used to examine a structural equation model linking community attachment and involvement to newspaper use, local television news use, age, education, number of children in the home, localism, and population density. Among the results, we show that newspaper reading makes important contributions to both attachment and involvement, independently of the other variables in the model, while television news viewing does not. Error paths and correlations between the errors of the equations are estimated to aid future modeling work.
Modeling and wafer defect analysis in semiconductor automated material handling systems

Modeling and analysis of automated material handling systems in semiconductor manufacturing is difficult because of its complexity, the large amount of data originating from different sources as well as the often incomplete monitoring of transport processes. This article proposes an automated method and tool for building high level models of such systems based on transport logs, routing information and static system data. On the basis of this model, a method for tracing and correlating lot movements is presented and used to support system experts in locating fab areas that most likely caused defects measured on wafers, e.g. due to temporarily contaminated clean room air. In addition, several methods to analyze the transport systems performance, such as the determination of lot detours or causes for a potentially critical load of certain system parts are discussed.
”It's so cold and impossible to make friends”: challenges of multicultural relationships in Finland

This study focused on long-lasting multicultural relationships from Finnish spouses’ perspectives. What are those special features that challenges multicultural relationships in Finland? The narrative method was used as the methodological approach. The research data were obtained through the use of narrative interviews with 11 Finnish people (8 women, 3 men). Every participant had been married to a foreign spouse for over 7 years (15 years on average). The results found describe everyday challenges as expressed by the Finnish spouses. Life in Finland, married to an immigrant, brought special challenges to the relationship, such as lack of knowledge of the Finnish language, religion, cultural traditions and roles, employment difficulties, and economic worries. Various life situations and threats from the environment were, however, handled so that the relationships lasted. In conclusion, models for the survival of multicultural marriages were introduced in this research. These include the stable relationship model, empowering relationship model, and relationship tinged with insecurity model.
CoFence: A collaborative DDoS defence using network function virtualization

With the exponential growth of the Internet use, the impact of cyber attacks are growing rapidly. Distributed Denial of Service (DDoS) attacks are the most common but damaging type of cyber attacks. Among them SYN Flood attack is the most common type. Existing DDoS defense strategies are encountering obstacles due to their high cost and low flexibility. The emerging of Network Function Virtualization (NFV) technology introduces new opportunities for low-cost and flexible DDoS defense solutions. In this work, we propose CoFence — a DDoS defense mechanism which facilitates a collaboration framework among NFV-based peer domain networks. CoFence allows domain networks help each others handle large volumes of DDoS attacks through resource sharing. Specifically, we focus on the resource allocation problem in the collaboration framework. Through CoFence a domain network decides the amount of resource to share with other peers based on a reciprocal-based utility function. Our simulation results demonstrate the designed resource allocation system is effective, incentive compatible, fair, and reciprocal.
Height Reduction of the Axial-Mode Open-Ended Quadrifilar Helical Antenna

This letter addresses the miniaturization of the open-ended quadrifilar helical antenna for satellite VHF frequency band telemetry links systems. The miniaturization is achieved using combinations of sinusoidal profiles, and several designs are obtained using an optimization process based on intensive electromagnetic simulations. The design and experimental validation are reported in this letter, and a significant height reduction from 48% to 72% is obtained using various combinations of sinusoidal profiles (i.e., wires mathematically described by sinusoidal functions) without a significant degradation of the radiation pattern, directivity, and polarization purity. Moreover, the input matching is slightly improved for the compact antennas. It was observed that the efficiency and gain do not decrease linearly with the reduction of the antenna height.
Ionic basis for excitability of normal rat kidney (NRK) fibroblasts

Ionic membrane conductances of normal rat kidney (NRK) fibroblasts were characterized by whole‐cell voltage‐clamp experiments on single cells and small cell clusters and their role in action potential firing in these cells and in monolayers was studied in current‐clamp experiments. Activation of an L‐type calcium conductance (GCaL) is responsible for the initiation of an action potential, a calcium‐activated chloride conductance (GCl(Ca)) determines the plateau phase of the action potential, and an inwardly rectifying potassium conductance (GKir) is important for the generation of a resting potential of approximately −70 mV and contributes to action potential depolarization and repolarization. The unique property of the excitability mechanism is that it not only includes voltage‐activated conductances (GCaL, GKir) but that the intracellular calcium dynamics is also an essential part of it (via GCl(Ca)). Excitability was found to be an intrinsic property of a fraction (∼25%) of the individual cells, and not necessarily dependent on gap junctional coupling of the cells in a monolayer. Electrical coupling of a patched cell to neighbor cells in a small cluster improved the excitability because all small clusters were excitable. Furthermore, cells coupled in a confluent monolayer produced broader action potentials. Thus, electrical coupling in NRK cells does not merely serve passive conduction of stereotyped action potentials, but also seems to play a role in shaping the action potential. J. Cell.

Differential and common correlates of non-suicidal self-injury and alcohol use among community-based adolescents

Abstract Non-suicidal self-injury (NSSI) and under-age alcohol use are dysfunctional coping behaviors used to alleviate negative feelings. However, little is known regarding what mechanisms lead to engagement in NSSI as opposed to alcohol use, or what might infl uence co-occurrence of these behaviors. A total of 2,590 secondary school students (aged 12–17) from fi ve Australian states completed self-report questionnaires measuring NSSI, alcohol use and a range of sociodemographic and psychosocial factors. The fi ndings suggest that adolescent engagement in NSSI is associated with more internal factors, such as psychological distress, poor coping and problem-solving skills, whereas alcohol use is associated with age and gender, as well as more external factors, such as social support and coping by turning to others. Co-morbidity between alcohol use and NSSI is associated with a combination of these factors. Implications of these fi ndings will be discussed with regard to prevention and early intervention initiatives.
