Ontology Based Approach for Event Detection in Twitter Datastreams

In this paper, we present a system that attempts to interpret relations in social media data based on automatically constructed dataset-specific ontology. Twitter data pertaining to the real world events such as the launch of products and the buzz generated by it, among the users of Twitter for developing a prototype of the system. Twitter data is filtered using certain tag-words which are used to build an ontology, based on extracted entities. Wikipedia data on the entities are collected and processed semantically to retrieve inherent relations and properties. The system uses these results to discover related entities and the relationships between them. We present the results of experiments to show how the system was able to effectively construct the ontology and discover inherent relationships between the entities belonging to two different datasets.
Evaluation of Dried Blood Spots Collected on Filter Papers from Three Manufacturers Stored at Ambient Temperature for Application in HIV-1 Drug Resistance Monitoring

As more HIV-infected people gain access to antiretroviral therapy (ART), monitoring HIV drug resistance (HIVDR) becomes essential to combat both acquired and transmitted HIVDR. Studies have demonstrated dried blood spots (DBS) are a suitable alternative in HIVDR monitoring using DBS collected on Whatman 903 (W-903). In this study, we sought to evaluate two other commercially available filter papers, Ahlstrom 226 (A-226) and Munktell TFN (M-TFN), for HIVDR genotyping following ambient temperature storage. DBS were prepared from remnant blood specimens collected from 334 ART patients and stored at ambient temperature for a median time of 30 days. HIV-1 viral load was determined using NucliSENS EasyQ® HIV-1 v2.0 RUO test kits prior to genotyping of the protease and reverse transcriptase regions of the HIV-1 pol gene using an in-house assay. Among the DBS tested, 26 specimens had a viral load ≥1000 copies/mL in all three types of filter paper and were included in the genotyping analysis. Genotyping efficiencies were similar between DBS collected on W-903 (92.3%), A-226 (88.5%), and M-TFN (92.3%) filter papers (P = 1.00). We identified 50 DR-associated mutations in DBS collected on W-903, 33 in DBS collected on A-226, and 48 in DBS collected on M-TFN, resulting in mutation detection sensitivities of 66.0% for A-226 and 88.0% for M-TFN when compared to W-903. Our data indicate that differences among filter papers may exist at this storage condition and warrant further studies evaluating filter paper type for HIVDR monitoring.
Supporting the transition of disabled students from university to practice placement

A modified action research project was undertaken to evaluate the effectiveness of a pre-placement procedure in facilitating eight disabled physiotherapy students’ transitions from university to practice. Feedback was gathered from the students, practice educators, visiting and academic tutors via questionnaire. Thematic analysis identified four main themes: ‘Procedure’; ‘Student in Control’; ‘Communication’; and ‘Disclosure’. The procedure was generally effective in supporting these students. Recommendations were made for: the need for ownership of the procedure from all stakeholders; the development of more effective communication systems; and the need for appropriate disability awareness training for all academic and practice-based staff.
Report on Social Desirability, Midpoint and Extreme Responding in TALIS 2013

This paper investigated the effects of response styles in cross-cultural contexts. The authors used data on social desirability, extreme and midpoint responding, and the scale scores of 17 constructs related to the teaching profession, which were collected from 76,887 teachers in 18 countries in the Teaching and Learning International Survey (TALIS). Main findings are: (1) a 10-item social desirability scale demonstrated partial invariance of a positive and a negative impression management factor; (2) a general response style, representing a continuum ranging from response amplification to moderation, was extracted with social desirability and extreme responding as positive indicators and midpoint responding as a negative indicator; (3) social desirability and the general response style at the country level were negatively correlated with country affluence and educational achievement; (4) social desirability and the general response style were more strongly correlated with constructs of teacher efficacy and job satisfaction than other constructs at both the individual and country level; and (5) correction of response styles had negligible effects on cross-cultural differences in these constructs. Ce document de travail etudie les effets des styles de reponses au sein des contextes interculturels. Les auteurs se sont servis des donnees en matiere de « desirabilite sociale », des reponses extremes et medianes, et des scores des echelles de mesures de 17 constructions relatives a la profession d’enseignant. Ces donnees ont ete recueillies aupres de 76,887 enseignants dans 18 pays de l’enquete internationale sur l’enseignement et l’apprentissage (TALIS). Les principales conclusions sont : (1) l’echelle de mesure de 10 items en matiere de desirabilite sociale a demontre une invariance partielle du facteur de gestion du processus d’influence des perceptions positives ou negatives. (2) une reponse d’ordre general, representant un continuum s’etendant d’une amplification de la reponse a la moderation, a ete extraite avec la desirabilite sociale et une reponse extreme comme indicateurs positifs et reponse mediane comme indicateur negatif ; (3) la desirabilite sociale et la reponse d’ordre general au niveau des pays etaient liees de maniere negative avec la richesse des pays et le niveau d’education ; (4) la desirabilite sociale et la reponse d’ordre general etaient plus fortement liees avec les constructions relatives a l’efficacite des enseignants et la satisfaction dans l’exercice de leur profession que les autres constructions au niveau individuel et au niveau des pays ; et (5) la correction des styles de reponses avaient des effets negligeables sur les differences interculturelles de ces constructions.
Distributed simulation model for computer integrated manufacturing

We discuss the necessity of a simulation tool which can handle a large and complex manufacturing system under CIM environment, and then consider problems incurred by developing such a large system model. A distributed simulation model developed on a distributed computer system is then shown to be a promising method to cope with the problems. Lastly, a time bucket method with time warp mechanism is proposed for the synchronization of the distributed simulation and its computational features are investigated by modeling a virtual factory on six workstations connected by the ethernet.
The Enduring Effects of Early Literacy Experiences: A Retrospective Interview Study

This qualitative interview study was designed to understand how early literacy experiences continue to influence individuals as they become adult readers. The study utilized a case study methodology that allowed detailed descriptions of participants‟ recollections of early literacy experiences and descriptions of the participants‟ current reading habits. The researcher, working from a constructivist paradigm, worked to find evidence to explore what features of early reading experiences might compel an individual to turn to reading again and again, or to choose to abstain from reading. The following research questions guided this study: “What specific memories do adult readers recall about early reading experiences? ” “What is the nature of the influence of early reading experiences on lifelong reading habits as reported by adults? ” and “What is the nature of the influence of lifelong reading habits on social and professional life as reported by
Glycoprotein D homologs in herpes simplex virus type 1, pseudorabies virus, and bovine herpes virus type 1 bind directly to human HveC(nectin-1) with different affinities.

Distinct subsets of human receptors for alphaherpesviruses mediate the entry of herpes simplex virus (HSV), pseudorabies virus (PrV), or bovine herpes virus type 1 (BHV-1) into cells. Glycoprotein D (gD) is essential for receptor-mediated entry of all three viruses into cells. However, the gD homologs of these viruses share only 22-33% amino acid identity. Several entry receptors for HSV have been identified. Two of these, HveA (HVEM) and HveC (nectin-1), mediate entry of most HSV-1 and HSV-2 strains and are bound directly by HSV gD. A third receptor, HveB (nectin-2), mediates entry of HSV-2 and only a limited number of HSV-1 strains. HveB and HveC can also serve as entry receptors for PrV, whereas only HveC can serve this function for BHV-1. We show here that gD from PrV and BHV-1 binds directly to the human receptors that mediate PrV and BHV-1 entry. We expressed soluble forms of PrV gD and BHV-1 gD using recombinant baculoviruses and purified each protein. Using ELISA, we detected direct binding of PrV gD to HveB and HveC and direct binding of BHV-1 gD to HveC. Biosensor analysis revealed that PrV gD had a 10-fold higher affinity than HSV-1 gD for human HveC. In contrast, the binding of BHV-1 gD to HveC was weak. PrV gD and HSV-1 gD competed for binding to the V domain of HveC and both inhibited entry of the homologous and heterologous viruses. These data suggest that the two forms of gD bind to a common region on human HveC despite their low amino acid similarity. Based on affinities for human HveC, we predict a porcine HveC homolog may be important for PrV infection in its natural host, whereas a BHV-1 infection in its natural host may be mediated by a receptor other than a bovine HveC homolog.
Conformational analysis of stiff chiral polymers with end-constraints

We present a Lie-group-theoretic method for the kinematic and dynamic analysis of stiff chiral polymers with end constraints. The first is to determine the minimum energy conformations of stiff polymers with end constraints and the second is to perform normal mode analysis based on the determined minimum energy conformations. In this paper, we use concepts from the theory of Lie groups and principles of variational calculus to model such polymers as inextensible or extensible chiral elastic rods with coupling between stiffnesses. This method is general enough to include any stiffness and chirality parameters in the context of elastic filament models with the quadratic elastic potential energy function. As an application of this formulation, the analysis of DNA conformations is discussed. We demonstrate our method with examples of DNA conformations in which topological properties such as writhe, twist and linking number are calculated from the results of the proposed method. Given these minimum energy conformations, we describe how to perform the normal mode analysis. The results presented here build both on recent experimental work in which DNA mechanical properties have been measured and theoretical work in which the mechanics of non-chiral elastic rods has been studied.
Random Graph Model Simulations of Semantic Networks for Associative Concept Dictionaries

Word association data in dictionary form can be simulated through the combination of three components: a bipartite graph with an imbalance in set sizes; a scale-free graph of the Barabasi-Albert model; and a normal distribution connecting the two graphs. Such a model makes it possible to simulate the complex features in degree distributions and the interesting graph clustering results that are typically observed for real data.
A Transition-based System for Universal Dependency Parsing

This paper describes the system for our participation in the CoNLL 2017 Shared Task: Multilingual Parsing from Raw Text to Universal Dependencies. In this work, we design a system based on UDPipe1 for universal dependency parsing, where multilingual transition-based models are trained for different treebanks. Our system directly takes raw texts as input, performing several intermediate steps like tokenizing and tagging, and finally generates the corresponding dependency trees. For the special surprise languages for this task, we adopt a delexicalized strategy and predict basing on transfer learning from other related languages. In the final evaluation of the shared task, our system achieves a result of 66.53% in macro-averaged LAS F1-score.
Thickness Measurement of Metallic Plates With an Electromagnetic Sensor Using Phase Signature Analysis

This paper presents a simple model that can predict the phase signature of eddy current sensors over nonmagnetic metallic plates. In contrast to the magnitude of the eddy current signal, which generally significantly decreases with an increase in liftoff, the phase signature appears to be virtually immune to liftoff variations and, therefore, can be more reliably used in field eddy current testing. A parameter that encapsulates the coil geometry factors can be obtained through calibration with samples of known properties. This geometry parameter can then be used in the simple model to predict the phase signature of this sensor over any plate with any thickness. The use of this new model provides a fast and accurate method to measure plate thickness. Measurements and finite-element (FE) simulations made for two sample coils next to copper and aluminum plates of various thicknesses verified the theory and the proposed method.
3D modeling with three-view drawings

When modeling new geometries, artists and modelers tend to habitually document their creative imaginations through illustrating a set of three-view 2D images. These images are also easy to obtain for any geometry that already exists either in reality or in the cyberspace. However, due to the ambiguity of these three-view images in defining 3D models, automatic reconstruction of a geometry from them still carries serious technical limitations. This paper introduces a new system for rapid modeling of 3D free-form meshes from three-view images with the interactive user aid indicated via sketching. Distinct from the existing rapid sketching based 3D modeling methods, such as [Igarashi et al. 1999; Nelean et al. 2007], all of which require users to interactively illustrate the shape lines of the target object, the new system only expects users to select unwanted corners' shape lines from a set of 3D shape lines automatically extracted according to the input three-view images. For the model created through the Boolean operation, a particular UV mapping can be established that maps, via a one-to-one relationship, the input three-view images as texture onto the corresponding three sides of the constructed geometry.
Performance Enhancement Scheme for Wireless LAN under Bursty Channel

As wireless channel is bursty in nature, a two-state Markov channel model that considers the impact of bursty characteristics of channel errors is introduced into the analysis of operation and performance of saturated IEEE 802.11 DCF in this paper. A new scheme IDCF to exploit the information on the channel burstiness is further proposed to enhance the performance of DCF. The main idea of IDCF is to differentiate the handling of collision and data packet corruption at the sender. By adopting a persistent re-transmission approach according to the instantaneousness of the channel error, the performance of IEEE 802.11 DCF can be improved. Simulations are conducted and simulation results show that our analysis is accurate, and our proposed IDCF scheme does improve the performance in terms of throughput soundly.
Digestion in the pig between 7 and 35 d of age 6. The digestion of hydrolyzed milk and soya-bean proteins

1. Four pelleted diets were prepared containing milk or isolated soya-bean protein (ISP) as the major protein source. The milk and ISP were given either as intact proteins or partially (0·65) hydrolyzed with papain before feeding. 2. The diets were given ad lib. to thirty-two pigs from 7–28 d of age. The pigs were slaughtered at 28 d of age. 3. Weight gains, food conversion ratios and nitrogen balances of pigs given diets containing milk protein were better than those of diets containing ISP (231 g/d, 0·80 and 11·5 g/d compared to 209 g/d, 0·88 and 9·00 g/d respectively) 4. Partial hydrolysis of proteins before feeding did not affect the performance of the pigs. 5. Apparent digestibilities of N before the ileum and in the whole tract were 0·78 and 0.94 for the pigs given the ISP diets and 0·86 and 0·97 for the pigs given the milk-protein diets. 6. Retention time of ISP diets in the whole digestive tract was 1475 min and that of the milk-protein diets was 1089min. 7. pH of digesta in the stomach was 5·0–5·3 for all diets and increased to 6·9–7.1 in the ileum. 8. There were no differences in flows of total N and protein N to the ileum and lower digestive tract between the pigs given the intact- and hydrolyzed-protein diets. 9. Apparent absorptions of N in the stomach, duodenum and jejenum were greater in the pigs given diets containing hydrolyzed proteins than in those given diets containing the intact proteins. 10. Flows of total N and protein N to the ileum tract were greater when the pigs were given the ISP diets than when they were given the milk-protein diets. 11. Hydrolysis of proteins before feeding resulted in a reduced trypsin and chymotrypsin activity in the duodenum and pancreas. 12. Retention of dietary N in the carcass was greater in pigs given the milk-protein diets (0·79) than in those given the ISP diets (0·68).
Two-dimensional proton nuclear magnetic resonance investigation of the synthetic deoxyribonucleic acid decamer d(ATATCGATAT)2.

In this study two-dimensional NMR techniques (COSY and NOESY) have been used in conjunction with one-dimensional NMR results to complete the assignment of the proton NMR spectrum of the double-stranded DNA decamer, d(ATATCGATAT)2, and to obtain qualitative information about numerous interproton distances in this molecule and some limited information about conformational dynamics. COSY and NOESY measurements have been combined to systematically assign many of the resonances from the H1' and H2',2" sugar protons to specific nucleotides in the double helix. This method relies on the fact that sugar protons within a specific nucleotide are scalar coupled and that base protons (AH8, GH8, TH6, and CH6) in right-handed helices can interact simultaneously with their own H2',2" sugar protons and those of the adjacent (5'-3') nucleotide attached to its 5' side (i.e., XpA not ApX). A COSY experiment is used to identify sugar resonances within a residue whereas the NOESY experiment allows the neighboring sugar to be connected (linked). The CH5 and CH6 resonances in the spectrum can immediately be identified by the COSY experiment. The methyl protons of thymine residues exhibit strong through-space interbase interactions both with their own TH6 proton and with AH8 proton on the adjacent (5'-3') adenine residue. These interactions are used both to make assignments of the spectra and to establish that the thymine methyl groups are in close proximity to the AH8 protons of adjacent adenine residues [Feigon, J., Wright, J. M. , Leupin, W. , Denny, W. A. , & Kearns, D. R. (1982) J. Am. Chem. Soc. 104, 5540]. (ABSTRACT TRUNCATED AT 250 WORDS)

HMM triangle relative entropy concepts in sequential change detection applied to vision-based dim target manoeuvre detection

The quick detection of abrupt (unknown) parameter changes in an observed hidden Markov model (HMM) is important in several applications. Motivated by the recent application of relative entropy concepts in the robust sequential change detection problem (and the related model selection problem), this paper proposes a sequential unknown change detection algorithm based on a relative entropy based HMM parameter estimator. Our proposed approach is able to overcome the lack of knowledge of post-change parameters, and is illustrated to have similar performance to the popular cumulative sum (CUSUM) algorithm (which requires knowledge of the post-change parameter values) when examined, on both simulated and real data, in a vision-based aircraft manoeuvre detection problem.
Clustering Spam Campaigns with Fuzzy Hashing

Identifying spamming botnets is essential to defeat spammers and reduce the harm caused by spam emails. The first step to uncover these botnets is the identification of spam campaigns. Simple methods looking for common identifiers in emails, such as URL or email addresses, are inefficient due to the emergence of obfuscation techniques like URL shortening. In this paper we propose a new method based on fuzzy hashing to cluster spam with common goals into the same spam campaign. Fuzzy hashing allows us to identify emails with similar contents even though usual identifiers are obfuscated. Using the proposed method we process a three year long dataset that consists of 540 thousand spam emails. The efficiency of the proposed method is assessed by inspecting the characteristics of the top 100 campaigns found. Finally, we present typical behaviors of the uncovered spam campaigns and the corresponding botnets.
Integrins Regulate Microtubule Nucleating Activity of Centrosome through Mitogen-activated Protein Kinase/Extracellular Signal-regulated Kinase Kinase/Extracellular Signal-regulated Kinase (MEK/ERK) Signaling*

Background: Centrosomal microtubule nucleation is important in the formation of the microtubule cytoskeleton. Results: An integrin mutant that suppresses MEK/ERK signaling substantially reduces microtubule nucleation. Expression of activated RAF-1 restores nucleation inhibited by the mutant integrin. Conclusion: Integrins promote microtubule nucleation by regulating MEK/ERK signaling. Significance: Environmental cues provided by cell-matrix adhesion contribute to the regulation of the microtubule nucleating activity of the centrosome. Microtubule nucleation is an essential step in the formation of the microtubule cytoskeleton. We recently showed that androgen and Src promote microtubule nucleation and γ-tubulin accumulation at the centrosome. Here, we explore the mechanisms by which androgen and Src regulate these processes and ask whether integrins play a role. We perturb integrin function by a tyrosine-to-alanine substitution in membrane-proximal NPIY motif in the integrin β1 tail and show that this mutant substantially decreases microtubule nucleation and γ-tubulin accumulation at the centrosome. Because androgen stimulation promotes the interaction of the androgen receptor with Src, resulting in PI3K/AKT and MEK/ERK signaling, we asked whether these pathways are inhibited by the mutant integrin and whether they regulate microtubule nucleation. Our results indicate that the formation of the androgen receptor-Src complex and the activation of downstream pathways are significantly suppressed when cells are adhered by the mutant integrin. Inhibitor studies indicate that microtubule nucleation requires MEK/ERK but not PI3K/AKT signaling. Importantly, the expression of activated RAF-1 is sufficient to rescue microtubule nucleation inhibited by the mutant integrin by promoting the centrosomal accumulation of γ-tubulin. Our data define a novel paradigm of integrin signaling, where integrins regulate microtubule nucleation by promoting the formation of androgen receptor-Src signaling complexes to activate the MEK/ERK signaling pathway.
