TEXTNET: a network-based approach to text handling

Textnet is a new system for structuring text. The Textnet approach uses one uniform data structure to capture graphlike pools of text, as well as embedded hierarchical structures. By using a semantic network formalism of nodes connected by typed links, the relationships between neighboring pieces of text are made explicit. Also described is our partial implementation of the Textnet approach, which makes use of an object-oriented window/menu-driven user interface. Users peruse the network by moving among object menus or by reading text along a path through the network. In addition, critiquing, reader linking, searching, and jumping are easily accessible operations. Finally, the results of a short trial with users are presented.
The Current State of Graph Databases

Graph Database Models is increasingly a topic of interest the database realm. The representation of data in the form of a graph lends itself well to structured data with a dynamic schema. This paper goes over current applications and implementations of graph databases, giving an overview of the different types available and their application. Due wide spread of graph algorithms and models, no standard system or query language has been defined for graph databases. Research and industry adoption will determine the future direction of graph databases.
Playing in the woods: youth, leisure and the performance of gender relations in rural Newfoundland

Based on qualitative interviews and focus groups with youth (12–24 years) living in rural, coastal Newfoundland, Canada, we examine how leisure practices within this context served to reproduce and naturalize localized gender relations. More specifically, we argue that the participants drew upon dominant discursive constructions of rural leisure to reiteratively enact a binary distinction between the ‘town’ as a space of constraint, youth-adult tensions, and consumerism in contrast to the freedom and privacy of the ‘woods’. This dichotomy was mapped onto gender binaries, where the town was coded as feminine and the woods, masculine. We argue that these constructions served to mark the boundaries of normative gender leisure practices in the production of embodied gender subjectivities.
Chronic interleukin‐6 alters the level of synaptic proteins in hippocampus in culture and in vivo

There is now considerable evidence that the level of expression of the proinflammatory cytokine, interleukin‐6 (IL‐6), is increased in the central nervous system (CNS) during neuroinflammatory conditions such as occurs in neurological disorders and in disease and injury. However, our understanding of the consequences of increased expression of IL‐6 on the CNS is still limited, especially with respect to the developing nervous system, which is known to be particularly vulnerable to environmental factors. To address this issue, we investigated the properties of cultured hippocampal neurons exposed chronically to IL‐6 during the main period of morphological and physiological development, which occurs during the first 2 weeks of culture. IL‐6 was tested at 500 U/mL, considered to reflect a pathophysiologic concentration. The morphological features of neuronal development in the control and IL‐6‐treated cultures appeared similar. However, Western blot analysis showed a significant reduction in the level of Group‐II metabotropic receptors (mGluR2/3) and L‐type Ca2+ channels in the IL‐6‐treated cultures. A similar reduction in mGluR2/3 and L‐type Ca2+ channel protein was observed in transgenic mice that over‐express IL‐6 in the CNS through astrocyte production starting early in development. Analysis of Ca2+ signals produced by spontaneous synaptic network activity in the hippocampal cultures and effects of a mGluR2/3 agonist and antagonist showed that the reduced levels of mGluR2/3 impact on the functional properties of hippocampal synaptic network activity. These results have important implications relative to the mechanisms responsible for altered CNS function during conditions associated with increased levels of IL‐6 in the CNS.
An experimental study on substrate coupling in bipolar/BiCMOS technologies

The parasitic influence of the substrate can lead to a significant performance degradation of advanced high-speed and RF circuits. Hence, a careful circuit layout is necessary, and shielding measures such as guard rings must usually be applied. However, this might not be sufficient for high-performance circuits. Moreover, such measures often lead to an increased chip size. Therefore, not only the layout but also the technology itself should be optimized to suppress substrate coupling as much as possible. In this work, different technology-related options such as high-resistivity and SOI substrates, transistor isolation techniques, and shielding methods are investigated. Their influence on substrate coupling is determined up to 50 GHz by measurements of special test structures. The observed behavior is thoroughly explained so that guidelines for technology development and circuit design can be derived. This paper focuses primarily on RF and high-speed ICs fabricated in advanced bipolar or BiCMOS technologies using p/sup -/ substrates, although the results apply also to (RF-)CMOS circuits with such substrate materials.
Flexible Data-Driven Security for Android

Android allows users to cancel the installation of apps whenever requested permissions to resources seem inappropriate from their point of view. Since permissions can neither be granted individually nor changed after installation, this results in rather coarse, and often too liberal, access rules. We propose a more fine-grained security system beyond the standard permission system. With our system, it is possible to enforce complex policies that are built on temporal, cardinality, and spatial conditions ("notify if data is used after thirty days'', "blur data outside company's premises'', etc.). Enforcement can be done by means of modification or inhibition of certain events and the execution of additional actions. Leveraging recent advances in information flow tracking technology, our policies can also pertain to data rather than single representations of that data. For instance, we can prohibit a movie from being played more than twice even if several copies have been created. We present design and implementation of the system and provide a security and performance analysis.
Predicting Query Duplication with Box-Jenkins Models and Its Applications

Many previous works of Peer-to-Peer traffic characterization and modeling focused their attention on the distribution of query contents. However, few has been done towards a better understanding of the time series distribution of these queries, which is vital for system performance. To remedy this situation, this paper characterizes query traffic by using automatic time series analysis to evaluate different linear models(Box-Jenkins models and some simple windowed-mean models) for predicting the number of duplicated queries from 10 minutes to 2 hours into the future. Both the predictive power and the computational costs of these models are evaluated over 318,942,450 real world Gnutella queries collected over 3 months. We find the number of duplicated queries is consistently predictable. Simple, practical models like AR perform well on prediction. To show that these characteristics have a wide range of potential applications, we propose two enhancement to existing search results caching and load balancing algorithms. Our simulation study shows that our methodology works quite well in both scenarios in terms of efficiency and effectiveness. The main contribution of this paper lies in: (1) proposing new measurement techniques on Gnutella, (2) characterizing and modeling peer-to-peer query traffic with Box-Jenkins Models, (3) presenting a general enhancement to existing performance optimization algorithm in P2P systems.
Consanguineous marriage and human evolution.

Mate choice among early human groups and in many historical populations was subject to both demographic and social constraints, ensuring that most unions were between couples who had coinherited substantial proportions of their genomes from common ancestors. Even in populations in which close consanguineous marriage was proscribed, community endogamy would have been sufficient to ensure high levels of homozygosity. Consanguineous marriage remains the choice of an estimated 10.4% of the global population, although there has been an overall decline in its popularity, especially in developed countries. Recent studies have indicated that the shift from consanguineous marriage to panmixia has been accompanied by a reduction in homozygosity. The concomitant predicted decrease in incidence of both recessive single-gene disorders and more common adult-onset diseases will have a significant impact on the health of future generations.
An ACT-R Process Model of the Signal Duration Phenomenon of Vigilance

Performance on tasks that require sustained attention can be impacted by various factors that include: signal duration, the use of declarative memory in the task, the frequency of critical stimuli that require a response, and the event-rate of the stimuli. A viable model of the ability to maintain vigilance ought to account for these phenomena. In this paper, we focus on one of these critical factors: signal duration. For this we use results from Baker (1963), who manipulated signal duration in a clock task where the second hand moved in a continuous swipe motion. The critical stimuli were stoppages of the hand that lasted for 200, 300, 400, 600, or 800 ms. The results provided evidence for an interaction between condition and time-on-task, where performance declined at a faster rate as the signal duration decreased. In this paper, we describe an ACT-R model that uses fatigue mechanisms from Gunzelmann et al. (2009) that were proposed to account for the impact of sleep loss on sustained attention performance. The research demonstrates how those same mechanisms can be used to understand vigilance task performance. This illustrates an important foundation for predicting and tracking vigilance decrements in applied settings, and validates a mechanism that creates a theoretical link between the vigilance decrement and sleep loss.
Radioreceptor Assay for Prolactin and Other Lactogenic Hormones

A radioreceptor assay with a sensitivity of 5 nanograms per milliliter has been developed for mammalian and avian pituitary prolactin, placental lactogenic hormones, and humnan growth hormone, using a membrane receptor preparation isolated from rabbit mammary glands. Prolactin preparations inhibited the binding of [125I]prolactin to receptors in direct proportion to the biological potency of these preparations. Thus, the radioreceptor assay provides a convenient and simnple assay for hormones which have lactogenic activity.
Changes in the male voice during puberty: Speaking and singing voice parameters

This prospective, longitudinal study investigates the relationship between different parameters of the male speaking and singing voice during pubertal development. The data obtained consisted of 122 acoustic, laryngographic and clinical recordings of 26 musically untrained boys at different stages of puberty as defined by Tanner. The data show that: 1. The maximum changes in voice parameters occur between Tanner “G” stages 3 and 4. 2. The semitone range for the modal singing voice does not alter significantly throughout Tanner “G” stages 1 to 5. 3. There is an excellent correlation between the quantitatively measured singing range of modal voice (as shown on the laryngograph) and the keyboard derived perceptive singing range. 4. There is a constant relationship between the speaking fundamental frequency and the lowest singing frequency. The relevance of these parameters to clinical and musical practice is discussed.
Gendered Narratives in Spain

Women have traditionally been under-represented in the global sports media in terms of the amount of coverage dedicated to women's sport compared to men's. There have also been qualitative differences in the manner of reporting of women's and men's sports, reflecting the patriarchal attitudes dominant in society. This article explores the extent to which these traditional differences exist today in the Spanish print media. Drawing on data analysed from a sample of Spanish newspapers during the summer Olympic Games of 2004 in Athens, we carried out an empirical analysis of the amount of coverage dedicated to women's sports and research of a more qualitative nature which focuses on a detailed evaluation of the narratives employed, the images published and the political commentary surrounding women's events and female athletes. While the gender gap in the coverage of the Olympic Games in Spain is narrowing and ideologies regarding masculinity and femininity are gradually changing, gendered discursive strategies and subtexts prevent this process from evolving further.
Neuropsychological Rehabilitation: Theory, models, therapy and outcome

The intensive centre-based programme at the Oliver Zangwill Centre for Neuropsychological Rehabilitation based in Ely, Cambridgeshire, United Kingdom was modelled on other well-established holistic programmes (namely, those developed by Yehuda Ben-Yishay and George Prigatano). Its services commenced in 1996 for adults with non-progressive brain injury. Following referral, a preliminary assessment is conducted to determine suitability for the programme, which leads to a discussion between staff, the client and family regarding whether the individual is likely to benefit from the holistic approach. Clients who enter the next phase participate in a two-week detailed multidisciplinary assessment and are assigned an individual programme coordinator and supported to set goals through a collaborative process. Clients then commence the intensive rehabilitation phase which entails a combination of tailored individual therapy sessions and group therapy interventions that are structured over four to five days each week for several weeks (typically 12 weeks). The integration phase involves ongoing therapy within the Centre over two to three days each week for several weeks (typically 12 weeks) with increasing emphasis placed on the application of strategies and activity participation in the client’s home and community settings. This long-awaited book represents a comprehensive account of the classic and contemporary theories and models that underpin holistic rehabilitation approaches and provides an in-depth description of the therapeutic milieu, processes and outcomes of the Oliver Zangwill Centre (OZC). Considerable thought has gone into the overall structure, sections and chapters of the book, which encompass background and theory (Section 1), group interventions (Section 2), case illustrations (Section 3), and outcomes (Section 4). The first chapter of Section 1 provides an enjoyable overview of major changes and historical developments in rehabilitation. A balanced critique of influential theories and models is presented as the foundation for the NEUROPSYCHOLOGICAL REHABILITATION 2011, 21 (1), 141–144
Compact algorithm for strictly ML ellipse fitting

A very compact algorithm is presented for fitting an ellipse to points in images by maximum likelihood (ML) in the strict sense. Although our algorithm produces the same solution as existing ML-based methods, it is probably the simplest and the smallest of all. By numerical experiments, we show that the strict ML solution practically coincides with the Sampson solution.
SWSE: Answers Before Links!

We present a system that improves on current document-centric Web search engine technology; adopting an entity-centric perspective, we are able to integrate data from both static and live sources into a coherent, interlinked information space. Users can then search and navigate the integrated information space through relationships, both existing and newly materialised, for improved knowledge discovery and understanding.
Interactions between form and motion cues in the visual perception of biological motion

The seminal work by Cutting, Moore, and Morrison (1988) ascertained that a treadmill point light walker is most effectively masked by visual noise constructed of scrambled elements of the same walker. That finding demonstrates that the perception of coherent global form from point-light elements depends on the integration of local motion trajectories. Most biological motion displays incorporate not just biological motion cues, but also cues to translation. That is, displays often depict a figure walking across the field of view. The perception of global motion defined by direction of translation has been well established in studies utilizing random dot kinematograms (e.g. Edwards & Badcock, 1995). Thus the possibility exists that the perception of biological motion can reflect the integration of global form derived from local motion trajectories and global motion derived from direction of translation. The results presented here illustrate that the direction of translation of masks constructed of both biological motion trajectories and non-biological linear trajectories, like those used by Edwards and Badcock (1995), influence the ability to detect translating biological form-from-motion.
Achalasia cardia associated with esophageal varices: a therapeutic dilemma

A 63-year-old male, chronic alcohol consumer, presented with progressively increasing dysphagia of 6 months duration. Upper gastrointestinal endoscopy revealed dilated esophagus with residue along with esophageal varices. Esophageal manometry revealed findings suggestive of classic achalasia cardia. Endoscopic ultrasound (EUS) examination revealed peri-esophageal collaterals as well as prominent perforators at lower end of esophagus. The co-existence of varices with achalasia is very rare and this case posed a difficult therapeutic dilemma as risk of bleeding from the varices limited the treatment options available. This case was successfully treated with EUS-guided botulinum toxin injection.
Power-Efficient Virtual Machine Placement and Migration in Data Centers

In this paper, we propose a power-efficient solution for virtual machine placement and migration in a fat tree data center network. This solution reduces power consumption as well as job delay by aggregating virtual machines to a few hyper visors and migrating communicating parties to close locations. In this work, we consider OpenFlow as the implementation protocol. In an OpenFlow environment, a centralized controller oversees job loads, virtual machine requirements and hardware availability. Given observation of such global knowledge, the OpenFlow controller can schedule jobs and distribute virtual machines accordingly. As jobs change and flows shift, the OpenFlow controller dynamically adjusts virtual machine assignments by aggregating virtual machines to close locations in order to save energy. With this placement and migration proposal, more jobs can operate concurrently with close sources and destinations of flows, thus both job and flow delay can be reduced.
Prevascularized bone tissue engineering

Tissue engineering has been an active field of research for several decades now. However, the number of successful clinical applications in the field of tissue engineering are limited and can mainly be found in thin or avascular tissues like skin and cartilage. One of the current limitations of tissue engineering is the inability to provide sufficient blood supply in the initial phase after implantation. Insufficient vascularization after implantation can result in nutrient limitations, which can result in suboptimal integration of, and cell death in tissue engineered constructs. Several strategies to improve vascularization after implantation have been studied in the past. These include angiogenic growth factor delivery, scaffold design to facilitate angiogenesis, and in vivo prevascularization. This thesis explores a relatively new method to improve vascularization; in vitro prevascularization. The rationale of this method is that endothelial cells can form a prevascular network in another tissue during in vitro culture. After implantation of the resulting construct, the prevascular network can anastomose to the vasculature of the host and thus become a functional, perfused vascular network that provides the construct with nutrients. This will result in a faster vascularization and thus a better survival of the implant.
Surgical Outcomes after Traumatic Vertebral Fractures in Patients with Ankylosing Spondylitis

Objective Ankylosing spondylitis is an inflammatory rheumatic disease mainly affecting the axial skeleton. The rigid spine may secondarily develop osteoporosis, further increasing the risk of spinal fracture. In this study, we reviewed fractures in patients with ankylosing spondylitis that had been clinically diagnosed to better define the mechanism of injury, associated neurological deficit, predisposing factors, and management strategies. Methods Between January 2003 and December 2013, 12 patients with 13 fractures with neurological complications were treated. Neuroimaging evaluation was obtained in all patients by using plain radiography, CT scan, and MR imaging. The ASIA Impairment Scale was used in order to evaluate the neurologic status of the patients. Management was based on the presence or absence of spinal instability. Results A total of 9 cervical and 4 thoracolumbar fractures were identified in a review of patients in whom ankylosing spondylitis had been diagnosed. Of these, 7 fractures were associated with a hyperextension mechanism. 10 cases resulted in a fracture by minor trauma. Posttraumatic neurological deficits were demonstrated in 11 cases and neurological improvement after surgery was observed in 5 of these cases. Conclusions Patients with ankylosing spondylitis are highly susceptible to spinal fracture and spinal cord injury even after only mild trauma. Initial CT or MR imaging of the whole spine is recommended even if the patient's symptoms are mild. The patient should also have early surgical stabilization to correct spinal deformity and avoid worsening of the patient's neurological status.
