Supervised Learning Based Approach to Aspect Based Sentiment Analysis

Aspect base sentiment analysis is a very popular concept in the machine learning era which is under the research domain still at the movement. This research mainly consist of the way of exploring the sentiment analysis based on the trained data set to provide the positive, negative and neutral reviews for different products in the marketing world. Most of the existing approaches for opinion mining are based on word level analysis of texts and are able to detect only explicitly expressed opinions. In aspect-based sentiment analysis (ABSA) the aim is to identify the aspects of entities and the sentiment expressed for each aspect. The ultimate goal is to be able to generate summaries listing all the aspects and their overall polarity. For this research mainly natural language and machine learning techniques are used. To train the application for the given data sets SVM (support vector machine) and ME (Maximum Entropy) classification algorithms have been used. Differentiation of the performance of the each algorithm will be analyzed through this research using the proven technologies available in the world like "Re call", "F-Measure" and Accuracy.
On the design and performance analysis of multisymbol encapsulated OFDM systems

A new multicarrier system, termed multisymbol encapsulated orthogonal frequency division multiplexing (MSE-OFDM), is proposed, in which one cyclic prefix (CP) is used for multiple OFDM symbols. The original motivation for the MSE-OFDM proposal is to reduce the redundancy due to the CP in static-channel environments. The authors then found that an alternative implementation of the system can be used to improve the robustness to frequency offset and reduce the peak-to-average power ratio (PAPR). Equalization and demodulation algorithms for the MSE-OFDM system are proposed. A new preamble and the corresponding frequency-offset and channel estimation techniques are studied for the MSE-OFDM system. Using the proposed MSE-OFDM preamble, the joint maximum likelihood (ML) estimation of the frequency offset and the channel impulse response (CIR) is investigated in this paper. Possible ways to reduce the joint estimation complexity, including exploitation of the preamble structure, approximation of the joint ML estimator, and fast Fourier transform (FFT) pruning, are discussed. The performance of the proposed MSE-OFDM systems and channel estimators are analyzed and verified through numerical simulations. An analysis on the bandwidth efficiency, the performance with frequency offset, and the PAPR of the MSE-OFDM system are also presented
Phosphatidylinositol 3 Kinase Activation and AMPA Receptor Subunit Trafficking Underlie the Potentiation of Miniature EPSC Amplitudes Triggered by the Activation of L-Type Calcium Channels

We have characterized a mechanism by which the amplitudes of miniature EPSCs (mEPSCs) in CA1 pyramidal neurons in rat hippocampal organotypic slice cultures are potentiated by approximately twofold after a series of depolarizing voltage pulses from –80 to +20 mV. The increase in mEPSC amplitudes is triggered by the activation of L-type calcium channels and is independent of NMDA receptor (NMDAR) activation but also requires calcium release from intracellular stores. The potentiation induced by depolarizing pulses does not alter the kinetic parameters of mEPSCs. The induction phase of this potentiation involves phosphatidylinositol 3 kinase (PI3 kinase) activation because it is blocked completely in the presence of the PI3 kinase inhibitors wortmannin and 2-(4-morpholinyl)-8-phenyl-4H-1-benzopyran-4-one (LY294002). Furthermore, we show that the maintenance phase of depolarizing pulse potentiation requires continued PI3 kinase activity because the application of either wortmannin or LY294002 results in a reversal to control levels of the amplitudes of mEPSCs. Finally, we demonstrate that the increase in mEPSC amplitudes is mediated by the increased expression of functional AMPA receptors (AMPARs) because the potentiation is blocked by N-ethylmaleimide, botulinum toxin A, and a variety of short-sequence peptides that disrupt the interaction of AMPAR subunits with proteins involved with the trafficking of these to the cell membrane. Our data are consistent with the notion that PI3 kinase and membrane fusion/trafficking events play a pivotal role in coordinating changes in synaptic strength, mediated by AMPA receptors, which are triggered by alterations in postsynaptic calcium concentrations whether these changes are initiated via NMDAR-dependent or NMDAR-independent routes.
Linguistic Patterns Detected Through a Prosodic Segmentation in Spontaneous Taiwan Mandarin Speech

This paper proposes that spontaneous speech, segmented into perceptually coherent prosodic constituents, is able to provide plentiful linguistic information in which clear patterns can be observed. We present pioneering studies with empirical and quantitative evidence, supporting the notion that prosodic units can be useful for the automatic processing of spontaneous speech. High inter-labelers’ consistency proves the applicability of human prosodic segmentation. A series of results on spontaneous Taiwan Mandarin speech suggest that linguistic patterns found in different linguistic aspects can in theory be used for processing and understanding spontaneous speech. In an automatic POS tagging experiment, it is demonstrated that transcripts with annotations of prosodic boundaries achieved a slightly better performance than the original transcripts with only the speaker turn annotation. Making use of prosodic boundaries, we can deal with the problem of disfluency more directly. With regard to lexical and discourse cue phrases, we also found them produced frequently and regularly at the prosodic boundaries.
Electrodialytic Transport Properties of Anion-Exchange Membranes Prepared from Poly(vinyl alcohol) and Poly(vinyl alcohol-co-methacryloyl aminopropyl trimethyl ammonium chloride)

Random-type anion-exchange membranes (AEMs) have been prepared by blending poly(vinyl alcohol) (PVA) and the random copolymer-type polycation, poly(vinyl alcohol-co-methacryloyl aminopropyl trimethyl ammonium chloride) at various molar percentages of anion-exchange groups to vinyl alcohol groups, Cpc, and by cross-linking the PVA chains with glutaraldehyde (GA) solution at various GA concentrations, CGA. The characteristics of the random-type AEMs were compared with blend-type AEMs prepared in our previous study. At equal molar percentages of the anion exchange groups, the water content of the random-type AEMs was lower than that of the blend-type AEMs. The effective charge density of the random-type AEMs increased with increasing Cpc and reached a maximum value. Further, the maximum value of the effective charge density increased with increasing CGA. The maximum value of the effective charge density, 0.42 mol/dm3, was obtained for the random-type AEM with Cpc = 4.2 mol % and CGA = 0.15 vol %. A comparison of the random-type and blend-type AEMs with almost the same Cpc showed that the random-type AEMs had lower membrane resistance than the blend-type ones. The membrane resistance and dynamic transport number of the random-type AEM with Cpc = 6.0 mol % and CGA = 0.15 vol % were 4.8 Ω cm2 and 0.83, respectively.
Detection of lines, line junctions and line terminations

This paper describes an optimal line detector for the one-dimensional case which is derived from Canny's criteria, and an efficient approach for the detection of line junctions and line terminations. The line detector is extended to the two-dimensional case by operating separately in the x and y directions. An efficient implementation using an infinite impulse response (IIR) filter is provided. This implementation has the additional advantage that increasing the filter scale affects neither temporal nor spatial complexity. The detection algorithm for junctions and terminations is divided into two steps. First, given the lines extracted from the original image, a local measure of line curvature is estimated using the mean of the dot products of orientation vectors within a given neighbourhood. The second step involves the localization of junctions and terminations. Experimental results using several synthetic and real images demonstrate the validity of the two methods.
Design and analysis of dynamic Huffman codes

A new one-pass algorithm for constructing dynamic Huffman codes is introduced and analyzed. We also analyze the one-pass algorithm due to Faller, Gallager, and Knuth. In each algorithm, both the sender and the receiver maintain equivalent dynamically varying Huffman trees, and the coding is done in real time. We show that the number of bits used by the new algorithm to encode a message containing t letters is < t bits more than that used by the conventional two-pass Huffman scheme, independent of the alphabet size. This is best possible in the worst case, for any one-pass Huffman method. Tight upper and lower bounds are derived. Empirical tests show that the encodings produced by the new algorithm are shorter than those of the other one-pass algorithm and, except for long messages, are shorter than those of the two-pass method. The new algorithm is well suited for on-line encoding/decoding in data networks and for tile compression.
A New Modeling Method for Intelligent Service Mobile Robot

And the system analysis and design agent-oriented based on POMDP are provided in the same time. Finally, the two case studies are given and the experimental results have shown efficiency and rationality of this modeling method.
Tree-based state tying for high accuracy acoustic modelling

The key problem to be faced when building a HMM-based continuous speech recogniser is maintaining the balance between model complexity and available training data. For large vocabulary systems requiring cross-word context dependent modelling, this is particularly acute since many such contexts will never occur in the training data. This paper describes a method of creating a tied-state continuous speech recognition system using a phonetic decision tree. This tree-based clustering is shown to lead to similar recognition performance to that obtained using an earlier data-driven approach but to have the additional advantage of providing a mapping for unseen triphones. State-tying is also compared with traditional model-based tying and shown to be clearly superior. Experimental results are presented for both the Resource Management and Wall Street Journal tasks.
Reduction and hole-repairing of 3D scan line point clouds based on the portable body measurement system

Scan line point clouds can be generated using the portable body measurement system. Because of high-density points located in the scan line, reduction becomes a necessary task in processing. After analyzed, the width decision method is adopted and the reduction effect relies on the value of T, when T=0.008D, the number of points is reduced to 42%. Meanwhile, due to occlusions, holes exist in the scan line of the body. To fill the holes, a new approach is proposed which is based on the spatial gray model. Firstly, the chord length is selected to be the threshold to determinate holes, then according to the principle of spatial gray model, SGM (1, 1) of the scan lines are established which help to complete hole-repairing successfully.
Corrective algorithm for esophageal voice cycle detection

In this paper a corrective solution for more accurate esophageal voice cycle marks detection is presented. While the algorithm developed in a previous work adapts the MDVP voice period marks to esophageal voice, it shows lacks when analyzing unsteady |a| vowel samples and with high levels of noise. The proposed solution is aimed to iteratively correct the parameters (n min and threshold) used in the previous algorithm. The corrective system filters the noise of voice recordings and then uses the output of the previous algorithm to calculate the most reliable fundamental frequency, based on the most stable part of the given signal. The results were acquired by comparing the pitch values of the previous algorithm with and without the proposed solution and the calculating the error against the real value. The corrective solution presents a considerable improvement in the accuracy of the voice cycle detection algorithm by reducing the standard deviation of the error dataset from 4.591 to 0.593 and the mean error value from 2.459 down to 0.370. Furthermore, it reduces up to a 54% all errors above 1%.
An answer to Hirasaka and Muzychuk: every p-Schur ring over C 3

In [HiMu] the authors, in their analysis on Schur rings, pointed out that it is not known whether there exists a non-Schurian p-Schur ring over an elementary abelian p-group of rank 3. In this paper we prove that every p-Schur ring over an elementary abelian p-group of rank 3 is in fact Schurian.
The Impact of Renal Dysfunction on the Long Term Clinical Outcomes of Diabetic Patients Undergoing Percutaneous Coronary Intervention in the Drug-Eluting Stent Era

Background Limited data are available regarding the association between renal dysfunction and clinical outcomes in diabetic patients undergoing percutaneous coronary intervention (PCI) in the drug-eluting stent (DES) era. Methods Between March 2003 and December 2010, 2,181 diabetic patients were enrolled in a single-center registry. We divided diabetic patients into a renal dysfunction group (n = 518) and a non-renal dysfunction group (n = 1,663) according to a baseline estimated glomerular filtration rate <60 mL/min/1.73 m2. Propensity score matching analysis was also performed. The primary outcome was cardiac death. Results The median follow-up duration was 48 months. The rate of cardiac death was higher in the renal dysfunction group than in the non-renal dysfunction group (14.3% vs. 3.0%, adjusted hazard ratio [HR] 3.63, 95% confidence interval [CI] 2.47 to 5.35, p<0.001). Similarly, the incidence of stent thrombosis was significantly higher in the renal dysfunction group than in the non-renal dysfunction group (4.1% vs. 1.4%, adjusted HR 1.90, 95% CI 1.02 to 3.56, p = 0.04). After 1:1 propensity score matching (502 pairs), patients with renal dysfunction still had a higher rate of cardiac death (13.3% vs. 4.8%, HR 2.58, 95% CI 1.52 to 4.38, p<0.001) although there was no significant difference in the rate of stent thrombosis (4.0% vs. 2.8%, HR 1.31, 95% CI 0.64 to 2.69, p = 0.47). Conclusions Renal dysfunction is associated with long-term mortality for diabetic patients undergoing PCI in the DES era.
CHUA'S ATOM

The response of a chaotic Chua's electronic circuit and that of an atom show interesting common features. Starting from the comparison of the qualitative behavior of bifurcation diagrams and electronic spectroscopic series of atoms we associate order–chaos transition with those of an electron passing from a quantized to a continous energy spectrum. The resulting atomic model suggests an analogy between the synchronization of two Chua's atoms and chemical covalent bonding.
The Use of Music in the Chronic Pain Experience: An Investigation into the Use of Music and Music therapy by Patients and Staff at a Hospital Outpatient Pain Clinic

This study uses mixed methodology research to examine the use of music in the chronic pain experience. One hundred and seven adult patients attending an outpatient pain clinic at a general hospital completed a patient survey. 91% rated music as somewhat important to them, 69% benefit from music listening and 43% changed their use of music due to chronic pain. 56% of respondents had an interest in availing of music therapy as part of their treatment. Three themes found in the qualitative results (music for relaxation, positive response to music and music for coping) corresponded with the highly rated reasons for listening to music in the quantitative survey (enjoyment, relaxation and tension relief). Music listening was more common than active participation in music.Seven staff members completed surveys on their use of music and thoughts on music therapy in this setting. Staff rated music as very beneficial for people with chronic pain and 100% saw a role for music therapy in the treatment of patients with chronic pain. This study is one of few to map how people with chronic pain use music to self-care and to explore the role of music therapy in a hospital out-patient pain department. It offers potential for music therapy to be offered as a non-pharmacological intervention to assist people in developing music-based resources and strategies for managing chronic pain. Further investigation is recommended.
Efficient implementation of a BDD package

Efficient manipulation of Boolean functions is an important component of many computer-aided design tasks. A package for manipulating Boolean functions based on the reduced, ordered, binary decision diagram (ROBDD) representation is described. The package is based on an efficient implementation of the if-then-else (ITE) operator. A hash table is used to maintain a strong canonical form in the ROBDD and memory use is improved by merging the hash table and the ROBDD into a hybrid data structure. A memory function for the recursive ITE algorithm is implemented using a hash-based cache to decrease memory use. Memory function efficiency is improved by using rules that detect when equivalent functions are computed. The usefulness of the package is enhanced by an automatic and low-cost scheme for recycling memory. Experimental results are given to demonstrate why various implementation trade-offs were made. These results indicate that the package described is significantly faster and more memory-efficient than other ROBDD implementations described in the literature. <<ETX>>
Analysis of 4-Phosphopantetheinylation of Polyhydroxybutyrate Synthase from Ralstonia eutropha: Generation of β-Alanine Auxotrophic Tn5 Mutants and Cloning of thepanD Gene Region

ABSTRACT The postulated posttranslational modification of the polyhydroxybutyrate (PHA) synthase from Ralstonia eutrophaby 4-phosphopantetheine was investigated. Four β-alanine auxotrophic Tn5-induced mutants of R. eutropha HF39 were isolated, and two insertions were mapped in an open reading frame with strong similarity to the panDgene from Escherichia coli, encodingl-aspartate-1-decarboxylase (EC 4.1.1.15 ), whereas two other insertions were mapped in an open reading frame (ORF) with strong similarity to the NAD(P)+ transhydrogenase (EC 1.6.1.1 ) alpha 1 subunit, encoded by the pntAA gene fromEscherichia coli. The panD gene was cloned by complementation of the panD mutant of R. eutropha Q20. DNA sequencing of the panD gene region (3,312 bp) revealed an ORF of 365 bp, encoding a protein with 63 and 67% amino acid sequence similarity to PanD from E. coli and Bacillus subtilis, respectively. Subcloning of only this ORF into vectors pBBR1MCS-3 and pBluescript KS− led to complementation of the panD mutants of R. eutropha and E. coli SJ16, respectively. panD-encodedl-aspartate-1-decarboxylase was further confirmed by an enzymatic assay. Upstream of panD, an ORF with strong similarity to pntAA from E. coli, encoding NAD(P)+ transhydrogenase subunit alpha 1 was found; downstream of panD, two ORFs with strong similarity topntAB and pntB, encoding subunits alpha 2 and beta of the NAD(P)+ transhydrogenase, respectively, were identified. Thus, a hitherto undetermined organization ofpan and pnt genes was found in R. eutropha. Labeling experiments using one of the R. eutropha panD mutants and [2-14C]β-alanine provided no evidence that R. eutropha PHA synthase is covalently modified by posttranslational attachment of 4-phosphopantetheine, nor did the E. coli panD mutant exhibit detectable labeling of functional PHA synthase from R. eutropha.
A Structural Equation Modeling Analysis of Parental Factors Underlying the Demand for Private Supplementary Tutoring in China

Purpose: Private supplementary tutoring has been increasingly used by parents as part of wider strategies to assist their children’s education careers in China. With a theoretical lens of parentocracy, this article aimed to investigate the influential parental factors underlying the demand for private tutoring, focusing on parents’ socioeconomic resources and attitudes toward education. Design/Approach/Methods: This article drew upon data from the 2014 iteration of the China Family Panel Studies. Structural equation modeling (SEM) analysis was employed to explore the influences of parental factors. Findings: The SEM analysis confirmed that parental income, education, and aspirations on children’s education had both direct and indirect positive effects through the mediating factor of role construction on demand for tutoring. A multiple-group analysis was further conducted, and the difference in the patterns for urban and rural parents was explored. Parental occupation had no impact on demand for tutoring for rural parents but had both direct and indirect effects for urban parents. Both direct and indirect effects of household income on demand for tutoring were greater for urban parents than for rural parents. Originality/Value: This article examined the direct and indirect influences of parental factors on demand for private tutoring and explored the differences in patterns for urban and rural parents in a quantitative way. Findings have implications for education inequality.
Factor analysis of the Schizophrenia Quality of Life Scale Revision 4 (SQLS-R4) Chinese version and related factors

Objectives. To validate the Schizophrenia Quality of Life Scale Revision 4 (SQLS-R4) Chinese version with factor analysis. We also investigated factors influencing quality of life results. Method. One hundred patients with schizophrenia participated in this study. Experienced psychiatrists evaluated each patient's current psychological condition to assure intact judgment. Participants then filled out the quality of life questionnaire, SQLS-R4. We used principal component analysis to analyze SQLS-R4 with oblique rotation. We also collected demographic data, another subjective and objective quality of life questionnaire, and information about the functional status of the participants at the same time. Multiple linear regression was used to analyze collected factors which may influence the quality of life of schizophrenic patients. Results. We extracted seven factors that explained a 68.1% variance in the patients' quality of life. The factors were relationships with others, loneliness, exhaustion, depressed thinking, somatic concerns, vitality, and worry. Conclusion. We found that the SQLS-R4 factor analysis provided insights into the structure of the quality of life of patients with schizophrenia. We also found that subjective social participation, subjective health, and depression were quality-of-life-related factors. Whether other factors influence the quality of life in patients with schizophrenia requires further investigation.
Improved Algorithm for Computing Convex Hull of Plane Point Set

An algorithm for computing the convex hull of scattered plane point set through the extreme points on the boundary of plane is proposed. According to the extreme points, the plane point set is divided into five zones. The four zones on the boundary contain all convex vertexes. By computing extreme points of subsets in the four marginal zones, a polygon that contains all convex vertexes is obtained. After eliminating the concave vertexes, it is the convex hull of plane point set. The algorithm is simple and clear, contains less Arithmetic, therefore it reduces the time complexity and computational complexity of the algorithm.
