A bootstrapping method for extracting attribute names with keys from the web

A large number of semi-structured documents (HTML documents) exist on the Web. To improve the accessibility of information related to an object, such as a product, human, or place, its attribute names and attribute values need to be extracted. Recently, many studies have aimed to extract attribute values automatically, whereas only a small number of studies have attempted to extract attribute names. Thus, we propose a method for extracting attribute names automatically. For the first time, we apply a bootstrapping algorithm to attribute name extraction in the area of information extraction. To solve a problem that is caused by applying a pure bootstrapping algorithm to attribute name extraction, we use keys, which are also extracted by a bootstrapping algorithm. We found that using extracted keys improve the accuracy of attribute name extraction.
proTF: a comprehensive data and phylogenomics resource for prokaryotic transcription factors

UNLABELLED Investigation of transcription factors (TFs) is of extreme significance for gleaning more information about the mechanisms underlying the dynamic transcriptional regulatory network. Herein, proTF is constructed to serve as a comprehensive data resource and phylogenomics analysis platform for prokaryotic TFs. It has many prominent characteristics: (i) detailed annotation information, including basic sequence features, domain organization, sequence homolog and sequence composition, was extensively collected, and then visually displayed for each TF entry in all prokaryotic genomes; (ii) workset was employed as the basic frame to provide an efficient way to organize the retrieved data and save intermediate records; and (iii) a number of elaborated tools for phylogenomics analysis were implemented to investigate the evolutionary roles of specific TFs. In conclusion, proTF dedicates to the prokaryotic TFs with integrated multi-function, which will become a valuable resource for prokaryotic transcriptional regulatory network in the post-genomic era.

A Comparison of Electronic Infrastructures in the Air Cargo Industry in the Netherlands and Hong Kong SAR

Reasons behind the failure and success of large-scale information systems projects continue to intrigue researchers. In particular in the airline industry very successful (passenger reservation) systems have been built which have totally changed the competitive arena of the industry. On the cargo side however attempts to implement large-scale community systems have largely failed across the globe. Air cargo parties are becoming increasingly aware of the importance of IT and, increasingly, they understand the value that IOS could provide for the total value chain performance. However, whereas in other sectors IOSs have been very successful, there are only fragmented examples of successful global systems in the air cargo community and the penetration of IOS in the air cargo industry is by no means pervasive. This paper describes the genesis and evolution of two IOSs in the air cargo community and identifies plausible explanations that lead one to be a success and one to be a failure. It draws on extensive fieldwork in Europe and in Hong Kong SAR that is complemented by secondary data analysis of relevant trade and company literature. We argue that in these two cases the complex, institutional and technical choices by the initiators of the system in terms of their competitive implications that were the main causes for the systems failure. The paper thus concludes that it was the institutional factors involved in the relationships of the stakeholders that led to the opposite manifestations of the two initiatives, and that such factors should be taken into account when designing and implementing large-scale information systems.
The Probability of Nontrivial Common Knowledge

We study the probability that two or more agents can attain common knowledge of nontrivial events when the size of the state space grows large. We adopt the standard epistemic model where the knowledge of an agent is represented by a partition of the state space. Each agent is endowed with a partition generated by a random scheme consistent with his cognitive capacity. Assuming that agentsʼ partitions are independently distributed, we prove that the asymptotic probability of nontrivial common knowledge undergoes a phase transition. Regardless of the number of agents, when their cognitive capacity is sufficiently large, the probability goes to one; and when it is small, it goes to zero. Our proofs rely on a graph-theoretic characterization of common knowledge that has independent interest.
A Gaussian mixture model based classification scheme for myoelectric control of powered upper limb prostheses

This paper introduces and evaluates the use of Gaussian mixture models (GMMs) for multiple limb motion classification using continuous myoelectric signals. The focus of this work is to optimize the configuration of this classification scheme. To that end, a complete experimental evaluation of this system is conducted on a 12 subject database. The experiments examine the GMMs algorithmic issues including the model order selection and variance limiting, the segmentation of the data, and various feature sets including time-domain features and autoregressive features. The benefits of postprocessing the results using a majority vote rule are demonstrated. The performance of the GMM is compared to three commonly used classifiers: a linear discriminant analysis, a linear perceptron network, and a multilayer perceptron neural network. The GMM-based limb motion classification system demonstrates exceptional classification accuracy and results in a robust method of motion classification with low computational load.
Biofluid Activated Microbattery for Disposable Microsystems

A flexible aluminum-silver oxide microbattery activated by a liquid electrolyte for on-demand operation is presented. Four different electrolytes are tested: 1) aqueous sodium hydroxide; 2) blood; 3) urine; and 4) saliva. To start the operation of the microbattery 8 μL of the target electrolyte is pipetted onto the surface of the microbattery. The microbattery is fabricated on a polyimide substrate using conventional microfabrication techniques. The proposed microbatteries have an interdigitated electrode geometry and a minimum footprint area of 12 mm2. Seven different batteries designs having different electrode width and spacing have been fabricated and characterized. The experimental results show energy densities up to 26.6 μW h cm-2μm-1, maximum voltage output of 1.75 V, maximum current output of 0.55 mA, maximum capacity of 7.17 μAh, and maximum operating time of 75 min.
Family Man or Conqueror? - Contested Meanings in an Engineering Company

This paper explores significant symbols within a multi-national company called Engco . First, the metaphor of Engco as a family was prevalent among middle and junior managers. Second, there was a corporate image conveyed by top management through glossy publications, a masculine image of conquering competitors and the physical environment. These contradictory symbols appeared to co-exist at different levels of the organisation. Third, a symbol that appeared common to the entire organisation, although increasingly contested, was that of engineering, an image generally associated with male actors. Fourth, more equivocal, were references to a 'golden age' for the company in the post war period, when manufacturing was in its heyday. The paper discusses how these symbols worked with and against each other. All the symbols were found to differing degrees to shape particular constructions of masculinity and femininity within the organisation, which limited the expression of identity of both men and women. The paper suggests that Engco's organisational culture was in flux, and discusses both the role of management at different levels of the organisation as creators and consumers of image and identity, and the organisational construction of gender. The paper takes a symbolic interpretative approach and discusses both the theoretical background and methodology employed.
Phylogenetic Ubiquity and Shuffling of the Bacterial RecBCD and AddAB Recombination Complexes

ABSTRACT RecBCD and AddAB are bacterial enzymes that share similar helicase and nuclease activities and initiate repair of DNA double-strand breaks by homologous recombination. Examination of the phylogenetic distribution of AddAB and RecBCD revealed that one or the other complex is present in most sequenced bacteria. In addition, horizontal gene transfer (HGT) events involving addAB and recBCD appear to be common, with the genes encoding one complex frequently replacing those encoding the other. HGT may also explain the unexpected identification of archaeal addAB genes. More than 85% of addAB and recBCD genes are clustered on the genome, suggesting operon structures. A few organisms, including the Mycobacteria, encode multiple copies of these complexes of either the same or mixed classes. The possibility that the enzymatic activities of the AddAB and RecBCD enzymes promote their horizontal transfer is discussed, and the distribution of AddAB/RecBCD is compared to that of the RecU/RuvC resolvases. Finally, it appears that two sequence motifs, the Walker A box involved in ATP binding and an iron-sulfur-cysteine cluster, are present only in subsets of AddB proteins, suggesting the existence of mechanistically distinct classes of AddB.
Automatic Block-Length Selection for the Dependent Bootstrap

Abstract We review the different block bootstrap methods for time series, and present them in a unified framework. We then revisit a recent result of Lahiri [Lahiri, S. N. (1999b). Theoretical comparisons of block bootstrap methods, Ann. Statist. 27:386–404] comparing the different methods and give a corrected bound on their asymptotic relative efficiency; we also introduce a new notion of finite-sample “attainable” relative efficiency. Finally, based on the notion of spectral estimation via the flat-top lag-windows of Politis and Romano [Politis, D. N. , Romano, J. P. (1995). Bias-corrected nonparametric spectral estimation. J. Time Series Anal. 16:67–103], we propose practically useful estimators of the optimal block size for the aforementioned block bootstrap methods. Our estimators are characterized by the fastest possible rate of convergence which is adaptive on the strength of the correlation of the time series as measured by the correlogram.
Analytical Placement of Hypergraphs | I

G lobal placement of hypergraphs is critical to modern physical implementation methodology for large timingdriven designs. Placement results are typically evaluated in terms of the half-perimeter wirelengths of hyperedges in the original circuit hypergraph. However, existing analytical placers rely on a heuristic transformation into a graph to enable classical linear and quadratic edgelength minimizations. As a result, optimizing a wrong objective leads to grossly suboptimal solutions, as con rmed by our experiments. We present a novel approach to minimization of the half-perimeter hyperedge wirelength without graph models using provably good approximations of multivariate piece-wise linear functions. Our algorithm is tested on industrial instances, particularly, in a top-down placement context.
RecOR complex including RecR N-N dimer and RecO monomer displays a high affinity for ssDNA

RecR is an important recombination mediator protein in the RecFOR pathway. RecR together with RecO and RecF facilitates RecA nucleoprotein filament formation and homologous pairing. Structural and biochemical studies of Thermoanaerobacter tengcongensis RecR (TTERecR) and its series mutants revealed that TTERecR uses the N-N dimer as a basic functional unit to interact with TTERecO monomer. Two TTERecR N-N dimers form a ring-shaped tetramer via an interaction between their C-terminal regions. The tetramer is a result of crystallization only. Hydrophobic interactions between the entire helix-hairpin-helix domains within the N-terminal regions of two TTERecR monomers are necessary for formation of a RecR functional N-N dimer. The TTERecR N-N dimer conformation also affects formation of a hydrophobic patch, which creates a binding site for TTERecO in the TTERecR Toprim domain. In addition, we demonstrate that TTERecR does not bind single-stranded DNA (ssDNA) and binds double-stranded DNA very weakly, whereas TTERecOR complex can stably bind DNA, with a higher affinity for ssDNA than double-stranded DNA. Based on these results, we propose an interaction model for the RecOR:ssDNA complex.
Ability Versus Trait Emotional Intelligence Dual Influences on Adolescent Psychological Adaptation

Emotional intelligence (EI) is reliably associated with better mental health. A growing body of evidence suggests that EI acts as a protective buffer against some psychosocial stressors to promote adaptation. However, little is known about how the two principle forms of EI (trait and ability) work together to impact underlying stressor-health processes in adolescence. One thousand one hundred and seventy British adolescents (mean age = 13.03 years; SD = 1.26) completed a variety of standardized instruments assessing EI; coping styles; family dysfunction; negative life events; socioeconomic adversity; depression and disruptive behavior. Path analyses found that trait and ability EI work in tandem to modify the selection and efficacy of avoidant coping to influence the indirect effect of stressors on depression but not disruptive behavior. Nevertheless, actual emotional skill (ability EI) appears dependent on perceived competency (trait EI) to realize advantageous outcomes. Findings are evaluated and discussed with reference to theoretical and practical implications.
A combined CWT-DWT method using model-based design simulator for partial discharges online detection

The suppression of noises is fundamental in onsite Partial Discharge (PD) measurements. For this purpose, the wavelet transform analysis method has been developed and it is a powerful tool for processing the transient and suddenly changing signals. As the wavelet transform possesses the properties of multi-scale analysis and time-frequency domain localization, it is also particularly suitable to process the suddenly changing signals of the partial discharge pulse (PD). In this paper, an improved Wavelet denoising method developed by a model-based design software is presented. Simulations are provided as well as some results obtained during laboratory experiment and on-line PD measurements. The new method efficiency of reducing noises is evaluated by comparing the frequency spectrum before and after filtering processes with other software and hardware methods.
AYUSH: A Technique for Extending Lifetime of SRAM-NVM Hybrid Caches

Recently, researchers have explored way-based hybrid SRAM-NVM (non-volatile memory) last level caches (LLCs) to bring the best of SRAM and NVM together. However, the limited write endurance of NVMs restricts the lifetime of these hybrid caches. We present AYUSH, a technique to enhance the lifetime of hybrid caches, which works by using data-migration to preferentially use SRAM for storing frequently-reused data. Microarchitectural simulations confirm that AYUSH achieves larger improvement in lifetime than a previous technique and also maintains performance and energy efficiency. For single, dual and quad-core workloads, the average increase in cache lifetime with AYUSH is 6.90, 24.06 and 47.62×, respectively.
Precoding for Distributed Space-Time Codes in Cooperative Diversity-Based Downlink

In this paper, we investigate the cooperative diversity concept for use in MIMO multi-cell networks. We show that, in such networks, cooperative diversity processing must be optimized to account for the variability of channel conditions across the cooperative devices. This can be done via distributed precoding and, in mobile networks, it is based realistically on channel statistics. The cooperative MIMO correlation matrix admits a special structure which is used to optimize the precoder. We investigate algorithms for exact error-rate and low-complexity approximated optimization. Gains are evaluated in multi-cell scenarios with collaborating base stations.
Field Dependence and Conformity of Rural Mexican and Urban Anglo-American Children

KAGAN, SPENCER. Field Dependence and Conformity of Rural Mexican and Urban AngloAmerican Children. CHILD DEVELOPMENT, 1974, 45, 765-771. A number of theoretical works support the hypothesis that rural Mexican children are more passive and compliant than urban Anglo-American children. Based on that hypothesis it was predicted that rural Mexican children would be more field dependent and conforming in situations traditionally used to measure those variables. Experiment 1 found rural Mexican children erred from the true upright by almost twice as many degrees as urban Anglo-American children in a portable rod-and-frame-type task. Experiment 2 found rural Mexican children were more conforming and more often expressed belief in their misleading peers than did urban Anglo-American children. Results were related to cultural differences in press sensitivity, need for achievement, and child-rearing practices.
Haemolysis in experimental cholestasis: Possible role of erythrocyte sialic acid

Because previous studies have suggested that red cell membrane sialic acid might be a determinant of survival in vivo, we examined the relationship between haemolysis, erythrocyte membrane sialic acid, and hepatic neuraminidase (sialidase) levels in experimental cholestatic jaundice in rats. Treatment of normal rat erythrocytes with neuraminidase in vitro resulted in a significant reduction in their survival in vivo and removal by the spleen. The degree of haemolysis was comparable to that previously found 12 days after bile duct ligation in rats. Bile duct ligation resulted in a significant increase in hepatic neuraminidase and a decrease in erythrocyte sialic acid. The findings are consistent with the hypothesis that one or more neuraminidases present in inreased amounts in the bile duct-ligated livers are responsible for the removal of sialic acid from circulating erythrocytes and subsequent removal of these cells in the spleen.
Better Understanding Students’ Self-Authorship via Self-Portraits

Understanding the complexity of students’ meaning making is essential for educators to foster students’ growth toward collegiate learning outcomes. An internally generated view of self, relationships, and knowledge, or the ability to “self-author,” enables students to think critically, develop intercultural maturity, and become good citizens and leaders (Baxter Magolda, 2004; Kegan & Lahey, 2009; King & Baxter Magolda, 2005; Torres, 2009). Because meaning making is shaped by both personal and environmental contexts that are difficult to draw out in interviews alone, our study explored a new avenue for garnering evidence related to self-authorship—employing selfportraiture as a data-gathering tool. The notion of thought and experience being inextricably interwoven with the esthetic dates back to the work of Dewey (1934). He claimed “the [esthetic] experience itself has a satisfying emotional quality because it possesses internal integration and fulfillment reached through ordered and organized movement” and “no intellectual activity is an integral [enduring] event . unless it is rounded out with this quality” (p. 38). The act of creating a selfportrait requires individuals to tap into an often underutilized and yet powerful interface between the mind, emotions, and imagination to present ideas in representational signs and symbols. As evidenced in Vivian’s quote at the start of this article, the power of such an experience may be unmatched by communications limited to words. In this article, we will situate this new approach in the self-authorship literature, share details of the method, and highlight an example portrait and the developmental insights that can be gained from it.
Visualization methods for outdoor see-through vision

Visualizing occluded objects is a useful applications of Mixed Reality (MR), which we call "see-through vision. " For this application, it is important to display occluded objects in such a manner that they can be recognized intuitively by the user.Here, we evaluated five visualization methods for see-through vision that help the user to intuitively recognize occluded objects in outdoor scenes: "elimination of occluding object," "ground grid," "overlaying model of occluding object," "top-down view," and "on-off switching of MR display. " As we applied a new handheld MR device for outdoor see-through vision, we conducted subjective experiments to determine the best combination of methods. The experimental results indicated the combination of showing the ground grid, overlaying the wire-frame models of occluding objects, and top-down view to be optimal, while it is not necessary to display occluding objects for outdoor see-through vision with a handheld device, because users can see them with the naked eye.
The Quamoco product quality modelling and assessment approach

Published software quality models either provide abstract quality attributes or concrete quality assessments. There are no models that seamlessly integrate both aspects. In the project Quamoco, we built a comprehensive approach with the aim to close this gap. For this, we developed in several iterations a meta quality model specifying general concepts, a quality base model covering the most important quality factors and a quality assessment approach. The meta model introduces the new concept of a product factor, which bridges the gap between concrete measurements and abstract quality aspects. Product factors have measures and instruments to operationalise quality by measurements from manual inspection and tool analysis. The base model uses the ISO 25010 quality attributes, which we refine by 200 factors and 600 measures for Java and C# systems. We found in several empirical validations that the assessment results fit to the expectations of experts for the corresponding systems. The empirical analyses also showed that several of the correlations are statistically significant and that the maintainability part of the base model has the highest correlation, which fits to the fact that this part is the most comprehensive. Although we still see room for extending and improving the base model, it shows a high correspondence with expert opinions and hence is able to form the basis for repeatable and understandable quality assessments in practice.
Sensor and Display Human Factors Based Design Constraints for Head Mounted and Tele-Operation Systems

For mobile imaging systems in head mounted displays and tele-operation systems it is important to maximize the amount of visual information transmitted to the human visual system without exceeding its input capacity. This paper aims to describe the design constraints on the imager and display systems of head mounted devices and tele-operated systems based upon the capabilities of the human visual system. We also present the experimental results of methods to improve the amount of visual information conveyed to a user when trying to display a high dynamic range image on a low dynamic range display.
