We present RelationFactory, a highly effective open source relation extraction system based on shallow modeling techniques. RelationFactory emphasizes modularity, is easily configurable and uses a transparent pipelined approach. The interactive demo allows the user to pose queries for whichRelationFactory retrieves and analyses contexts that contain relational information about the query entity. Additionally, a recall error analysis component categorizes and illustrates cases in which the system missed a correct answer.
Exploring memory hierarchy with ArchC

We present the cache configuration exploration of a programmable system, in order to find the best matching between the architecture and a given application. Here, programmable systems composed by processor and memories may be rapidly simulated making use of ArchC, an architecture description language (ADL) based on SystemC. Initially designed to model processor architectures, ArchC was extended to support a more detailed description of the memory subsystem, allowing the design space exploration of the whole programmable system. As an example, it is shown an image processing application, running on a SPARC-V8 processor-based architecture, which had its memory organization adjusted to minimize cache misses.
Employing Personal/Impersonal Views in Supervised and Semi-Supervised Sentiment Classification

In this paper, we adopt two views, personal and impersonal views, and systematically employ them in both supervised and semi-supervised sentiment classification. Here, personal views consist of those sentences which directly express speaker's feeling and preference towards a target object while impersonal views focus on statements towards a target object for evaluation. To obtain them, an unsupervised mining approach is proposed. On this basis, an ensemble method and a co-training algorithm are explored to employ the two views in supervised and semi-supervised sentiment classification respectively. Experimental results across eight domains demonstrate the effectiveness of our proposed approach.
Migration Review Tribunal Decisions in Student Visa Cancellation Appeals: Sympathy, Hardship and Exceptional Circumstances

Abstract This article examines the decisions of the Migration Review Tribunal (now the Administrative Appeals Tribunal) in relation to appeals of student visa cancellations. It draws on a 2010–11 study of appealed cases, and discusses both quantitatively and qualitatively the appeals and the decisions. The study builds on literature surrounding the regulation of migration and non-citizens within national borders by analysing the regulation of international students who occupy a hybrid space or status: as desired economic migrants and as non-citizens subject to strict migration enforcement if they breach visa conditions. The findings point to inconsistencies in decision-making, concerns regarding the internal processes of some education institutions and a broader concern with regard to how, or if, students are supported to appeal visa cancellations.
Training Family Medicine Residents in Effective Communication Skills While Utilizing Promotoras as Standardized Patients in OSCEs: A Health Literacy Curriculum

Introduction. Future health care providers need to be trained in the knowledge and skills to effectively communicate with their patients with limited health literacy. The purpose of this study is to develop and evaluate a curriculum designed to increase residents' health literacy knowledge, improve communication skills, and work with an interpreter. Materials and Methods. Family Medicine residents (N = 25) participated in a health literacy training which included didactic lectures and an objective structured clinical examination (OSCE). Community promotoras acted as standardized patients and evaluated the residents' ability to measure their patients' health literacy, communicate effectively using the teach-back and Ask Me 3 methods, and appropriately use an interpreter. Pre- and postknowledge, attitudes, and postdidactic feedback were obtained. We compared OSCE scores from the group that received training (didactic group) and previous graduates. Residents reported the skills they used in practice three months later. Results. Family Medicine residents showed an increase in health literacy knowledge (p = 0.001) and scored in the adequately to expertly performed range in the OSCE. Residents reported using the teach-back method (77.8%) and a translator more effectively (77.8%) three months later. Conclusions. Our innovative health literacy OSCE can be replicated for medical learners at all levels of training.
Childhood experiences of violence in perpetrators as a risk factor of intimate partner violence: a systematic review.

BACKGROUND Perpetrators' experiences of violence during childhood are considered a risk factor for intimate partner violence (IPV). The objective of this study is to systematically review the characteristics and quality of papers which analyse the association between being battered during childhood, witnessing marital violence as a child within the family of origin and having an absent or rejecting father and the occurrence of IPV. METHODS Nine scientific databases were consulted (1960-2004). After applying the exclusion criteria, 10 studies were analysed. Variables are sample characteristics, directionality/study design, IPV and perpetrators' childhood measurements, findings, limitations and interventions. RESULTS All the studies found an association. Conflict Tactics Scale was the main tool used to measure the IPV. Different instruments were used to measure violent childhood experiences in men as an exposure. Recall bias (seven papers) and retrospective data (four papers) were reported as the main methodological limitations. Despite these, 50% of the studies proposed treatments/preventive measures. CONCLUSION Our findings support the results of previous studies, implying that action recommendations within IPV prevention are still not evidence based. Methodological problems of the papers reviewed should be solved to obtain more useful data. Scientific evidence about the aetiology of IPV should be increased to guide effective prevention programmes.
A Control Theoretic Framework for Performance Optimization of IEEE 802.11 Networks

In this paper we propose to model the behavior of a WLAN from a control theoretic perspective to achieve optimal performance in terms of e.g. throughput or delay. Control theory has been commonly used in industrial applications to provide the analytical tools for the design of closed-loop systems, in order to guarantee stable operation without lessening the ability to react to changes. We therefore propose to model a WLAN as a closed loop, where the controlled system is the wireless network and the controller is a module which adjusts the parameters of the WLAN based on the observed state of the network.
Einstein Metrics and Smooth Structures on Non-Simply Connected 4-Manifolds

We analyze the existence or non-existence of Einstein metrics on 4-manifolds with non-trivial fundamental group and the relation with the differential structure considered. We conclude that for admissible pairs (n, m) in a large region of the integer lattice, the manifold nCP 2 #mCP2 admits infinitely many non-equivalent free actions of finite cyclic groups and there are no Einstein metrics which are group invariant. The main tools are Seiberg-Witten Theory, cyclic branched coverings of complex surfaces and symplectic surgeries.
Differential diagnostic CYFRA 21-1 level for benign and malignant pleural effusions: a meta-analysis in the Chinese population

Introduction Many studies have investigated the usefulness of cytokeratin 19 fragments (CYFRA 21-1) in pleural fluid for the differential diagnosis of benign (BPE) and malignant pleural (MPE) effusions. In the present meta-analysis, the reported studies on the diagnosis between CYFRA 21-1 and pleural effusion were assessed to summarize the diagnostic characteristics of CYFRA 21-1 in Chinese patients. Material and methods The data sources from the creation of each database up to January 2011 included Medline, Chinese National Knowledge Infrastructure, EMBASE, Cochrane Library, and bibliographies of review and original articles. Through a systematic literature search for publications, the data from 22 studies were summarized based on their discussions on the result of the CYFRA 21-1 assay in pleural effusion and differential diagnosis evaluation in the Chinese population. Results A total of 22 studies were available for analysis, and the high CYFRA 21-1 level in MPE was significantly associated with risk for lung cancer (standardized mean difference [SMD] = 1.65, 95% confidence interval [CI] = 1.48–1.82, Z = 18.97, p < 0.00001) compared with BPE. The CYFRA 21-1 level in pleural effusion (13 studies) was significantly higher than that in serum (SMD = 1.10, 95% CI = 0.71–1.48, Z = 5.59, p < 0.00001). The risk for squamous cell carcinoma (SCC) for CYFRA 21-1 was 1.03 (95% CI = 0.64–1.42, Z = 5.15, p < 0.00001) compared with that of adenocarcinoma (8 studies). The sensitivity of CYFRA 21-1 reported in the articles ranged from 46% to 94%, and the specificity ranged from 57% to 100%. The summary measure of the test characteristics derived from the summary receiver operating characteristic curve was 81% for both sensitivity and specificity (17 studies). Conclusions The measurement of pleural CYFRA 21-1 is likely to be a useful diagnostic tool for the confirmation of MPE.
The Method of Design Sine Grating based on Suboptimal PWM

In the structured light 3 d optical measurement field, the sinusoidal grating design is one of the research focuses. The traditional focus methods of generating sine pattern is not widely accepted because of many well known defects. While another traditional binary pattern generated from Ronchi grating needs defocusing processing, its application has also been a certain limit because of its projected pattern contrast ratio is not high.In this paper, we have proposed a designing sine grating method with the spatial modulation theory based on Suboptimal PWM in electronic engineering. Compared with Ronchi grating, this method of generating pattern has a better fringe contrast, and more simple defocusing requirements, so this method has a good practical economic value.
Automated variability analysis and testing of an E-commerce site.: an experience report

In this paper, we report on our experience on the development of La Hilandera, an e-commerce site selling haberdashery products and craft supplies in Europe. The store has a huge input space where customers can place almost three millions of different orders which made testing an extremely difficult task. To address the challenge, we explored the applicability of some of the practices for variability management in software product lines. First, we used a feature model to represent the store input space which provided us with a variability view easy to understand, share and discuss with all the stakeholders. Second, we used techniques for the automated analysis of feature models for the detection and repair of inconsistent and missing configuration settings. Finally, we used test selection and prioritization techniques for the generation of a manageable and effective set of test cases. Our findings, summarized in a set of lessons learnt, suggest that variability techniques could successfully address many of the challenges found when developing e-commerce sites.
Towards semantic city models

3D city modeling is a very demanding task. It suffers from the same problems as general bottom-up 3D acquisition processes. Whatever the 3D acquisition system, there are always objects and surfaces that yield meager performance. Often the problems are fundamental and cannot be resolved through more sophisticated bottom-up processing. If however, one knows what kind of objects are to be modeled – e.g. buildings – strong prior knowledge can be invoked. Inverse procedural modeling is a case in point. It yields more compact and more realistic models, yet requires a grammar to be created and then activated for the style at hand. The paper discusses style classification and the (initial) use of more generic architectural guidelines as ways to mitigate the problems with procedural grammars.
Integral Solution for the Microwave Background Anisotropies in Nonflat Universes

We present an efficient method of computing cosmic microwave background (CMB) anisotropies in nonflat universes. First, we derive the Boltzmann equation for CMB temperature and polarization fluctuations produced by scalar perturbations in a general Robertson-Walker universe. We then apply the integral method in order to solve this equation, writing temperature and polarization anisotropies as a time integral over a geometrical term and a source term. The geometrical terms can be written using ultraspherical Bessel functions, which depend on curvature. These cannot be precomputed, as for flat space. Instead, we solve their differential equation directly for selected values of the multipoles. The resulting computational time is comparable to the flat-space case, improving over previous methods by 2-3 orders of magnitude. This allows one to compute highly accurate CMB temperature and polarization spectra, matter transfer functions, and their CMB normalizations for any cosmological model, thereby avoiding the need to use the various inexact fitting formulae that exist in the literature.
A distributed recovery mechanism for actor-actor connectivity in wireless sensor actor networks

Wireless sensor actor networks (WSANs) consist of a number of sensor nodes and actor nodes in a distributed network. Sensor nodes collect data from environment and report them to actor nodes or to a sink node. Actor nodes coordinate to take decisions and accordingly take suitable actions. To coordinate, actor nodes must communicate with each other through their network connections. Therefore, actor-actor connectivity is vital to coordination. A node failure may lead to network partitioning. This paper proposes a distributed mechanism for recovering the connectivity failures among actors in their partitioned network. Sensor nodes are used to temporarily and rapidly re-establish actor-actor connectivity long before this connectivity is permanently re-established through movements of some actors. It is shown that the proposed mechanism increases the availability of connectivity while the actorspsila connectivity undergoes repair by actor movement. Simulation results also show a comparatively lower time to repair for our approach.
A New Hybrid Delivery Scheme for Efficient Video-on-Demand Services

In video-on-demand (VOD) system, a periodic broadcast technique like fast broadcasting scheme has been shown to be very effective for serving a popular video in reducing the demand on server bandwidth. A reactive server transmission approach like patching scheme is more suitable for the video that is not popular enough. However, these approaches are not suited for the instance that the level of demand on a video changing greatly with time. In this paper, we propose a novel adaptive hybrid delivery scheme which allocates adaptively transmission resources according to the varying client request rate. The scheme tries to dynamically search the optimal number of channel assigned to the video by the newly updated request rate so as to minimize the bandwidth requirement. Simulation results show that the scheme improves the performance of VOD service significantly in terms of total server bandwidth requirement
Sexual Violence Is #NotOkay: Social Reactions to Disclosures of Sexual Victimization on Twitter

Objective: The present study sought to characterize social reactions to disclosures of sexual violence that occurred online through the Twitter hashtag #NotOkay. Method: A sample of 306 original content, English-language tweets containing the hashtag #NotOkay were collected via the NVivo software addition NCapture over a period of 5 nonconsecutive weekdays. Qualitative content analysis was conducted by a 3-person team. Results: Ullman’s (2000) Social Reactions Questionnaire served as a preliminary coding guide. Resulting themes included egocentric and distracting social reactions (which are commonly classified as negative responses), as well as a range of positive social reactions (providing emotional support, providing tangible or informational aid, and expressing validation and belief). Advocacy and taking responsibility for social change also emerged as positive responses within the online forum. It unclear whether tweets that distracted from survivors’ experience by commenting broadly on the prevalence of violence, or by placing responsibility on perpetrators, would be considered as helpful or hurtful by survivors. Conclusion: The resulting classification of online social reactions to disclosure of sexual victimization differs from existing classification systems of in-person social reactions to disclosure, suggesting that online forums may offer a unique context for disclosing violence and receiving support. Online forums may also provide an opportunity for support providers to engage in advocacy and voice a desire for social change, forms of social support that may not be provided in the context of an in-person disclosure. Future research may examine whether survivors who disclose on social media receive the support they desire.
Methods for evaluating queries to Horn knowledge bases in first-order logic

Query languages and query processing are important topics in computer science and information technology, as they are widely used in practical applications. Query languages are usually designed so that intensional predicates can be defined by logic rules and query evaluation can be done in polynomial time in the size of the extensional relations. Studying query processing for a query language involves developing an evaluation method with a good data complexity for the language (e.g., with polynomial time data complexity if the language allows) and then developing various optimizations for the method. Datalog is a well-known rule language for deductive databases. It expresses a Horn fragment without function symbols of first-order logic. Programs in Datalog are required to be range-restricted in the sense that every variable occurring in the head of a program clause also occurs in the body of the clause. Datalog uses the traditional monotonic semantics. The extension Datalog¬ of Datalog allows negation in the bodies of program clauses and uses a non-monotonic semantics like the standard semantics for stratified Datalog¬ programs and the well-founded semantics for the general case. Interest in deductive databases and methods for evaluating Datalog or Datalog¬ queries intensified in the eighties and early nineties, but “a perceived lack of compelling applications at the time ultimately forced Datalog research into a long dormancy” [19]. As also observed by Huang et al. in their SIGMOD’2011 paper [19]:
GREM: Dynamic SSD Resource Allocation In Virtualized Storage Systems With Heterogeneous VMs

In a shared virtualized storage system that runs heterogeneous VMs with diverse IO demands, it becomes a problem for the hypervisor to cost-effectively partition and allocate SSD resources among multiple VMs. There are two straightforward approaches to solve this problem: either equally assigning SSDs to each VM or managing SSD resources in a fair competition mode. Unfortunately, they cannot fully utilize the benefits of SSD resources, particularly when the workloads frequently change and bursts or spikes of IOs occur from time to time. In this paper, we design a Global SSD Resource Management solution GREM, which aims to fully utilize SSD resources as “smart” cache under the consideration of performance isolation. In particular, GREM takes dynamic IO demands of all VMs into consideration to split the entire SSD space into a long-term zone and a short-term zone and cost-effectively updates the content of SSDs in these two zones. GREM is able to adaptively adjust the reservation for each VM inside the long-term zone based on their IO changes. GREM can further dynamically partition SSDs between longand shortterm zones during runtime by leveraging the feedbacks from both cache performance and bursty workloads. Experimental results show that GREM can capture the cross-VM IO changes to make correct decisions on resource allocation and thus obtain high IO hit ratio and low IO costs, compared with both traditional and recent caching algorithms. Keywords—Solid State Drives, resource allocation, virtualized storage systems, caching algorithms, bursty workloads
Continuous administration of bevacizumab plus capecitabine, even after acquired resistance to bevacizumab, restored anti-angiogenic and antitumor effect in a human colorectal cancer xenograft model

Vascular endothelial growth factor (VEGF)-neutralizing therapy with bevacizumab has become increasingly important for treating colorectal cancer. It was demonstrated that second-line chemotherapy together with bevacizumab after disease progression (PD) on first-line therapy including bevacizumab showed clinical benefits in metastatic colorectal and breast cancers (ML18147 trial, TANIA trial). One of the rationales for these trials was that the refractoriness to first-line therapy is caused by resistance to not so much bevacizumab as to the chemotherapeutic agents. Nevertheless, resistance to bevacizumab cannot be ruled out because VEGF-independent angiogenesis has been reported to be a mechanism of resistance to anti-VEGF therapy. In this study, we used a xenograft model with the human colon cancer HT-29 cells to investigate the mechanisms underlying the effect of continued administration of bevacizumab plus capecitabine even after resistance to bevacizumab was acquired. The combination of capecitabine plus bevacizumab exhibited significantly stronger antitumor and anti-angiogenic activities than did monotherapy with either agent. Capecitabine treatment significantly increased the intratumoral VEGF level compared with the control group; however, the combination with bevacizumab neutralized the VEGF. Among angiogenic factors other than VEGF, intratumoral galectin-3, which reportedly promotes angiogenesis both dependent on, and independently of VEGF, was significantly decreased in the capecitabine group and the combination group compared with the control group. In an in vitro experiment, 5-fluorouracil (5-FU), an active metabolite of capecitabine, inhibited galectin-3 production by HT-29 cells. These results suggested that capecitabine has a dual mode of action: namely, inhibition of tumor cell growth and inhibition of galectin-3 production by tumor cells. Thus, capecitabine and bevacizumab may work in a mutually complementary manner in tumor angiogenesis inhibition to overcome the resistance caused by angiogenic factors other than VEGF. These results suggest the clinical relevance and the mechanism of action of treatment with bevacizumab in combination therapy beyond PD.
