Sparql 1.1 and Rdf Faceted Browsing Sparql 1.1 and Rdf Faceted Browsing

On the Semantic Web, faceted browsing is a popular choice to support user navigation over RDF data. While existing tools provide powerful navigation and rich user experience, they require transforming the RDF data into a specific format or pre-processing the data to build particular indices and models. We show how the faceted navigation of RDF data can be directly supported by utilising the upcoming version of the standard RDF query language, SPARQL 1.1. By directly mapping faceted navigation to SPARQL queries, we enable navigating the large number of datasets currently available behind SPARQL endpoints. Secondly, we present algorithms necessary to support browsing data distributed across several SPARQL endpoints over the web. An empirical study that provides insights into the queries involved in faceted browsing and compares the different algorithms is also presented. 1Digital Enterprise Research Institute Galway, National University of Ireland Galway University Road, Galway, Ireland E-mail: fadi.maali@deri.org nikos.loutas@deri.org Copyright c © 2012 by the authors
Dynamical suppression of sea level rise along the Pacific coast of North America: Indications for imminent acceleration

[1] Long-term changes in global mean sea level (MSL) rise have important practical implications for shoreline and beach erosion, coastal wetlands inundation, storm surge flooding, and coastal development. Altimetry since 1993 indicates that global MSL rise has increased about 50% above the 20th century rise rate, from 2 to 3 mm yr−1. At the same time, both tide gauge measurements and altimetry indicate virtually no increase along the Pacific coast of North America during the satellite epoch. Here we show that the dynamical steric response of North Pacific eastern boundary ocean circulation to a dramatic change in wind stress curl, τxy, which occurred after the mid-1970s regime shift, can account for the suppression of regional sea level rise along this coast since 1980. Alarmingly, mean τxy over the North Pacific recently reached levels not observed since before the mid-1970s regime shift. This change in wind stress patterns may be foreshadowing a Pacific Decadal Oscillation regime shift, causing an associated persistent change in basin-scale τxy that may result in a concomitant resumption of sea level rise along the U.S. West Coast to global or even higher rates.
Compact quad-band power divider based on quad-mode stub loaded resonator

A compact quad-band equal power divider (PD) based on quad-mode stub loaded resonators (SLRs) and conventional Wilkinson power divider is proposed in this paper. The proposed SLR, analyzed by even/odd mode analysis method, can introduce four narrow passbands and provide more degrees of freedom to tune the resonant frequencies. A prototype of a quad-band equal PD centred at 1.5, 2.5, 3.5 and 5.2 GHz is fabricated. The predicted results on S parameters are compared with the measured ones and good agreement is found.
HARMONET: A Neural Net for Harmonizing Chorales in the Style of J. S. Bach

HARMONET, a system employing connectionist networks for music processing, is presented. After being trained on some dozen Bach chorales using error backpropagation, the system is capable of producing four-part chorales in the style of J.S. Bach, given a one-part melody. Our system solves a musical real-world problem on a performance level appropriate for musical practice. HARMONET's power is based on (a) a new coding scheme capturing musically relevant information and (b) the integration of backpropagation and symbolic algorithms in a hierarchical system, combining the advantages of both.
Golden Fish: An Intelligent Stream Cipher Fuse Memory Modules

In this paper, we use a high-order iterated function generated by block cipher as the nonlinear filter to improve the security of stream cipher. Moreover, by combining the published rounds function in block cipher and OFB as the nonlinear functional mode with an extra memory module, we enable to control the nonlinear complexity of the design. This new approach fuses the block cipher operation mode with two memory modules in one stream cipher. The security of this design is proven by the both periodic and nonlinear evaluation. The periods of this structure is guaranteed by the traditional Linear Feedback Shift Register design and the security of nonlinear characteristic is demonstrated by block cipher algorithm design itself, which is remarkably safer than the previous designs of stream cipher. We also can find such design style at SHA3.
Mining Labeled Data from Web-Scale Collections for Vocal Activity Detection in Music

This work demonstrates an approach to generating strongly labeled data for vocal activity detection by pairing instrumental versions of songs with their original mixes. Though such pairs are rare, we find ample instances in a massive music collection for training deep convolutional networks at this task, achieving state of the art performance with a fraction of the human effort required previously. Our error analysis reveals two notable insights: imperfect systems may exhibit better temporal precision than human annotators, and should be used to accelerate annotation; and, machine learning from mined data can reveal subtle biases in the data source, leading to a better understanding of the problem itself. We also discuss future directions for the design and evolution of benchmarking datasets to rigorously evaluate AI systems.
The Triggering of Orographic Rainbands by Small-Scale Topography

Abstract The triggering of convective orographic rainbands by small-scale topographic features is investigated through observations of a banded precipitation event over the Oregon Coastal Range and simulations using a cloud-resolving numerical model. A quasi-idealized simulation of the observed event reproduces the bands in the radar observations, indicating the model’s ability to capture the physics of the band-formation process. Additional idealized simulations reinforce that the bands are triggered by lee waves past small-scale topographic obstacles just upstream of the nominal leading edge of the orographic cloud. Whether a topographic obstacle in this region is able to trigger a strong rainband depends on the phase of its lee wave at cloud entry. Convective growth only occurs downstream of obstacles that give rise to lee-wave-induced displacements that create positive vertical velocity anomalies wc and nearly zero buoyancy anomalies bc as air parcels undergo saturation. This relationship is quantifie.
Providing a positive learning experience for international students studying at UK universities: A literature review

Much of the current literature relating to international students at university level tends to highlight their experiences from a deficit perspective and in some cases even problematises the experience for the student and university. Other studies tend to focus on recruitment and motivation rather than the lived experiences of the student, thereby providing little assistance to guide the student, academic and host university in their preparation for, and working with, the international student. International students choose to study in the United Kingdom for a variety of positive reasons. However, these factors have the potential to become stressors as the student makes the transition to studying in a foreign country. Rather than viewing these stressors from a negative perspective, this literature review identifies how, with planning, support and understanding, universities can provide and develop a positive experience for all concerned.
1-Methyl-4-phenylpyridinium induces synaptic dysfunction through a pathway involving caspase and PKCδ enzymatic activities

1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine administration has been used, in various mammalian species, as an experimental model of Parkinson's disease. The pathogenesis for such pharmacologically induced Parkinson's disease involves 1-methyl-4-phenylpyridinium (MPP+), the active metabolite of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine. This metabolite produces rapid degeneration of nigrostriatal dopaminergic neurons, which causes the parkinsonian syndrome. In this work, we show that injection of MPP+ into the presynaptic terminal of the squid giant synapse blocks synaptic transmission without affecting the presynaptic action potential or the presynaptic calcium currents. These effects of MPP+ were mimicked by the injection of an active form of caspase-3 and prevented by inhibitors of caspase-3 and protein kinase C δ. Ultrastructurally, MPP+-injected synapses showed a dramatic reduction in the number of neurotransmitter vesicles at the presynaptic active zone, as compared with control synapses. Otherwise, normal docking and clathrin-coated vesicles were observed, albeit at much reduced numbers. These results indicate that MPP+ acutely reduces presynaptic vesicular availability, not release, and that MPP+-induced pathogenesis results from presynaptic dysfunction that leads, secondarily, to dying-back neuropathy in affected neurons.
The Whole Set of Constitutive Promoters Recognized by RNA Polymerase RpoD Holoenzyme of Escherichia coli

The promoter selectivity of Escherichia coli RNA polymerase is determined by the sigma subunit with promoter recognition activity. The model prokaryote Escherichia coli contains seven species of the sigma subunit, each recognizing a specific set of promoters. The major sigma subunit, sigma-70 encoded by rpoD, plays a major role in transcription of growth-related genes. Concomitant with the increase in detection of promoters functioning in vivo under various stressful conditions, the variation is expanding in the consensus sequence of RpoD promoters. In order to identify the canonical sequence of “constitutive promoters” that are recognized by the RNA polymerase holoenzyme containing RpoD sigma in the absence of supporting transcription factors, an in vitro mixed transcription assay was carried out using a whole set of variant promoters, each harboring one base replacement, within the model promoter with the conserved -35 and -10 sequences of RpoD promoters. The consensus sequences, TTGACA(-35) and TATAAT(-10), were identified to be ideal for the maximum level of open complex formation and the highest rate of promoter opening, respectively. For identification of the full range of constitutive promoters on the E. coli genome, a total of 2,701 RpoD holoenzyme-binding sites were identified by Genomic SELEX screening, and using the reconfirmed consensus promoter sequence, a total of maximum 669 constitutive promoters were identified, implying that the majority of hitherto identified promoters represents the TF-dependent “inducible promoters”. One unique feature of the constitutive promoters is the high level of promoter sequence conservation, about 85% carrying five-out-of-six agreements with -35 or -10 consensus sequence. The list of constitutive promoters provides the community resource toward estimation of the inducible promoters that operate under various stressful conditions in nature.
Searches for Young Pulsars

I review the results of radio and X-ray searches for pulsations from young neutron stars, emphasizing work accomplished in the last five years. I cover undirected searches, as well as directed searches of pulsar wind nebulae, EGRET gamma-ray sources, and also the search for pulsations from "isolated neutron stars" (INSs) and "central compact objects".
Visualizing the Positional and Geometrical Variability of Isosurfaces in Uncertain Scalar Fields

We present a novel approach for visualizing the positional and geometrical variability of isosurfaces in uncertain 3D scalar fields. Our approach extends recent work by Pöthkow and Hege [ PH10 ] in that it accounts for correlations in the data to determine more reliable isosurface crossing probabilities. We introduce an incremental update‐scheme that allows integrating the probability computation into front‐to‐back volume ray‐casting efficiently. Our method accounts for homogeneous and anisotropic correlations, and it determines for each sampling interval along a ray the probability of crossing an isosurface for the first time. To visualize the positional and geometrical uncertainty even under viewing directions parallel to the surface normal, we propose a new color mapping scheme based on the approximate spatial deviation of possible surface points from the mean surface. The additional use of saturation enables to distinguish between areas of high and low statistical dependence. Experimental results confirm the effectiveness of our approach for the visualization of uncertainty related to position and shape of convex and concave isosurface structures.
Confocal scanning laser microscopy in the study of biofilm formation in tissues of the upper airway in otolaryngologic diseases

The full significance of bacterial biofilms in human chronic rhinosinusitis has yet to be determined. However, the corroboration of biofilms in vivo and the demonstration of the high capacity to form biofilms in vitro for all isolated bacteria, suggest a nexus between chronic rhinosinusitis and chronic inflammation or infection. Confocal scanning laser microscopy has proved a useful tool to analyze the structure of both the extracellular matrix exopolysaccharide and the cells that form the biofilms immersed in the tissue of the upper airway. Nevertheless, the possibility of viewing biofilms by an optical technique may also be helpful in ordinary practice in a global approach to these patients.
La influencia de las condiciones de escucha en las pruebas de lengua extranjera The Influence of Listening Conditions on Foreign Language Testing

This article focuses on listening conditions and their influence on the fairness of the foreign language oral comprehension tests that will begin to be administered for undergraduate admission in the 2011-12 academic year. A review of the literature on speech perception shows that foreign language intelligibility is affected by listening conditions, especially a) room acoustics due to reverberation and b) the presence of ambient noise, particularly voices inside and outside the classroom. These parameters affect hearing-impaired persons even more severely. The authors recommend using closed circumaural headphones for listening tests. Circumaural headphones are very common in universities, are commercially affordable and make it possible to test under standardised conditions by cancelling surrounding noise and reverberation. It is highly important to use a headphone reproduction system to conform to the laws on accessibility for the hearing impaired, which are frequently violated through ignorance of the factors that may affect many students, some of whom have very mild hearing impairment. If sound files can be played by the students, using computers or other systems that allow interactive playback, the organisation and administration of the test is facilitated and students can concentrate better and adapt the task to their memory capabilities, focussing on oral language understanding instead of auditory memory and retention capabilities. Audio-only material should be used, without video. In the creation of all material, language level, speech rate, recording quality and recording conditions should be controlled in order to avoid intelligibility differences.
Dose Finding – A Challenge in Statistics

A good understanding and characterization of the dose response relationship of any new compound is an important and ubiquitous problem in many areas of scientific investigation. This is especially true in the context of pharmaceutical drug development, where it is mandatory to launch safe drugs which demonstrate a clinically relevant effect. Selecting a dose too high may result in unacceptable safety problems, while selecting a dose too low may lead to ineffective drugs. Dose finding studies thus play a key role in any drug development program and are often the gate‐keeper for large confirmatory studies.
Sense of entitlement as a link between the influence of indulgent and inconsistent parenting on the perpetration of sexual coercion

AND INCONSISTENT PARENTING ON THE PERPETRATION OF SEXUAL COERCION by EVIN WINKELMAN RICHARDSON (Under the Direction of Leslie Gordon Simons) ABSTRACT The current study examines the impact of family of origin factors such as warmth and hostility between parents, inconsistent parenting, and overparenting during childhood on the perpetration of sexual coercion during emerging adulthood while examining feelings of entitlement as a possible mediator. Data from 711 undergraduate students were analyzed separately by gender using structural equation modeling. Results show that warmth and hostility between parents is significantly related to parenting behaviors (i.e., overparenting and inconsistent parenting) and that hostility between parents is associated with the perpetration of sexual coercion by the offspring in emerging adulthood for males. Also, findings suggest that while overparenting and inconsistent parenting during childhood is not directly associated with the perpetration of sexual coercion during emerging adulthood, they are strongly related to feelings of entitlement, which in turn was found to be associated with the perpetration of sexual coercion for males.
A software architecture for distributed workflow enactment with agents and web services

This dissertation details the development of a software architecture for an open, distributed, agent-based workflow enactment mechanism. This architecture is instantiated through the development of a demonstration system, which in turn is used as a source of validation. An important contribution of this work is that it reveals the existence of a synergistic relationship between service-oriented and agent-based computing. This relationship is that passive Web services can be liberated by the proactive and social nature of agents, which use the Web services as externally defined behaviors. In effect agent-based technologies provide the mechanism for services to seek work, enter into cooperative agreements and thus otherwise address the requirements of dynamic, heterogeneous environments. Furthermore, this dissertation advances the idea that conventional process description languages, for example the Business Process Execution Language for Web Services (BPEL4WS), can be used as a specification language for multiagent systems. The impact of this work is broad as it serves as a bridge from existing static views of workflow enactment to future agent-based workflow engines that can adapt the workflow based upon environmental dynamics.
Anxiety, hunger, and eating behavior.

In this study we examined the effects of anxiety and food deprivation on the amount of food consumed ad lib by dieters and nondieters. Eighty female college students served as subjects in an ostensible market research study in which an anxiety manipulation was embedded. Reassignment of the subjects to anxiety condition on the basis of self-reported anxiety produced a significant (p < .02) three-way interaction among level of anxiety, food deprivation, and dieting status. The results suggest that (a) for nondieters, anxiety suppresses hunger but has no effect when subjects are not initially hungry, and (b) for dieters, anxiety increases eating only when the subject is initially hungry. These results are interpreted in terms of Herman and Polivy's (1984) boundary model of eating. Researchers have long viewed the effects of anxiety on eating as depending primarily on the type of person involved. Normal (nonobese, nondieting) people, who are presumably responsive to their physiological state, are expected to react to anxiety or stress by eating less. The physiological effects of stress include the inhibition of gastric contractions and the elevation of blood sugar, both of which ought to suppress hunger. Thus the normal individual, who uses such internal cues (or their correlates) as the basis for the regulation of eating, ought to eat less when stressed. Expectations regarding the effect of stress on overweight people are more variable. Early psychodynamic views (summarized by Kaplan & Kaplan, 1957) held that eating may reduce anxiety for some people; these people, owing to their reliance on eating to assuage distress, will in all likelihood become overweight. By the same token, we may expect obese people to respond to distress by overeating. Bruch (1961) developed an interesting variation on this theme. She argued that early mislabeling may lead some people to confuse emotional distress with hunger and to respond to such distress with eating; naturally, responding to an inappropriately wide range of internal cues might well promote obesity. In contrast, Schachter, Goldman, and Gordon (1968) posited that obese people ignore internal (physiological) cues and regulate their eating on the basis of external (environmental) cues. Exclusive dependence on such cues can promote long-term weight gain, but the manipulation of internal cues (including those induced by anxiety) alone ought to have no effect on the obese person's eating. This theory, then, suggests that obese people neither undereat (as would normal weight people) nor
A Low Overhead Dynamic Path Scheme for Ad Hoc Networks

AODV is a famous routing protocol for mobile ad hoc networks. The routing path will not change during data transmission unless a link failure occurs. For the mobile nodes in an ad hoc network may move arbitrarily, some nodes in the routing path may turn to be redundant. On the other hand, when a link between nodes is tending to be broken, the nodes in the middle way of the link are turn to be valuable ones. In this paper, we propose a simple dynamic path scheme for ad hoc networks just by keeping little information in mobile nodes and turning on the overhearing function of mobile nodes. The simulation results show that the proposed scheme does improve the performance of the AODV protocol
The Secret Is To Follow Your Nose

This article presents an experiment in which route choice decisions made at road junctions are recorded. Such routes can be expressed as the sum of individual decisions made or potential decisions available throughout a journey. Relationships between these aggregate values are assessed statistically, indicating that participants’ decisions correlate more strongly with maximum angles of incidence of road center lines (leading from a junction) than to mean or minimum angles. One interpretation is that participants appear to be attempting to conserve linearity throughout their journey. However, informal observations of participants traversing urban grids cast doubt on the proposed theories of the conservation of angular linearity, requiring the theory’s modification. The resultant hypothesis combines principles of a conservation of linearity while also minimizing the angular difference between pairs of bearings; the key bearings are the directions of potential route choices and a perceived bearing of the wayfinding goal as judged from sequential instances of the observer’s location.
Natural language processing and information extraction: qualitative analysis of financial news articles

Quantitative financial data are today largely analyzed by automatic computer programs based on traditional or artificial intelligence techniques. Differently, qualitative data and, in particular, articles from on-line news agencies or from financial newspapers are not yet successfully processed. As a result, financial operators suffer from qualitative data-overload. The paper addresses the issue of the use of natural language processing and, in particular, information extraction, for processing qualitative financial data. The financial information extraction system under development at the University of Durham can identify specific kinds of information within a source article, producing a set of relevant templates which represent the most important information in the article and therefore reducing the operators' qualitative data-overload. The application has been designed in close contact with experts of the financial sector and can be fully customized by the user who can add new templates to the existing ones.
