Finding Opinion Strength Using Fuzzy Logic on Web Reviews

Determining the polarity and strength of opinions is an important research area over the last few years. The work challenges on opinion sentences and opinion holder extraction, opinion polarity judgment and also to measure the strength of polarity. In this paper we propose a convenient way using fuzzy techniques for analyzing opinion content in a review; our main goal is to analyze and to evaluate the sentiment in the review into a score for decision-making. The web contains product reviews and consumers are often forced to wade through many on-line reviews in order to make a product choice. We use techniques that decompose the review sentences and evaluate the individual characteristics of a product. Our task is performed in three steps: (1) mining product features that have been commented by customers; (2) identifying opinion sentences in each review and extracting the opinion phrases in each opinion sentence; (3) to measure the strength of opinion phrases to summarize the results. This paper introduces FOM (Fuzzy Opinion Miner), a supervised opinion orientation detection system that mines reviews to build a model of important product features, their evaluation by reviewers and the over all importance of the reviews.
Knowledge needs in the non-profit sector: an evidence-based model of organizational practices

Purpose – This paper aims to present findings from a study of non-profit organizations (NPOs), including a model of knowledge needs that can be applied by practitioners and scholars to further develop the NPO sector. Design/methodology/approach – A survey was conducted with NPOs operating in Canada and Australia. An analysis of survey responses identified the different types of knowledge essential for each organization. Respondents identified the importance of three pre-determined themes (quantitative data) related to knowledge needs, as well as a fourth option, which was a free text box (qualitative data). The quantitative and qualitative data were analyzed using descriptive statistical analyses and a grounded theory approach, respectively. Findings – Analysis of the quantitative data indicates that NPOs ' needs are comparable in both countries. Analysis of qualitative data identified five major categories and multiple sub-categories representing the types of knowledge needs of NPOs. Major categories are.
Poisson Noise Removal for Image Demosaicing

With increasing resolution of the sensors in camera detector arrays, acquired images are ever more susceptible to perturbations that appear as grainy artifacts called ‘noise’. In real acquisitions, the dominant noise model has been shown to follow the Poisson distribution, which is signal dependent. Most color image cameras today acquire only one out of the R, G, B values per pixel by means of a color filter array in the hardware, and in-built software routines have to undertake the task of obtaining the rest of the color information at each pixel through a process termed demosaicing. The presence of the Poisson noise can significantly degrade the output of a demosaicing algorithm. In this paper, we propose and compare two dictionary learning methods to remove the Poisson noise from the single channel images by directly solving a Poisson likelihood problem or performing a variance stabilizer transform prior to demosaicing. Experimental results on simulated noisy images as well as real camera acquisitions, show the advantage of these methods over approaches that remove noise subsequent to demosaicing.
Minimizing the Residual Topography Effect on Interferograms to Improve DInSAR Results: Estimating Land Subsidence in Port-Said City, Egypt

The accurate detection of land subsidence rates in urban areas is important to identify damage-prone areas and provide decision-makers with useful information. Meanwhile, no precise measurements of land subsidence have been undertaken within the coastal Port-Said City in Egypt to evaluate its hazard in relationship to sea-level rise. In order to address this shortcoming, this work introduces and evaluates a methodology that substantially improves small subsidence rate estimations in an urban setting. Eight ALOS/PALSAR-1 scenes were used to estimate the land subsidence rates in Port-Said City, using the Small BAse line Subset (SBAS) DInSAR technique. A stereo pair of ALOS/PRISM was used to generate an accurate DEM to minimize the residual topography effect on the generated interferograms. A total of 347 well distributed ground control points (GCP) were collected in Port-Said City using the leveling instrument to calibrate the generated DEM. Moreover, the eight PALSAR scenes were co-registered using 50 well-distributed GCPs and used to generate 22 interferogram pairs. These PALSAR interferograms were subsequently filtered and used together with the coherence data to calculate the phase unwrapping. The phase-unwrapped interferogram-pairs were then evaluated to discard four interferograms that were affected by phase jumps and phase ramps. Results confirmed that using an accurate DEM (ALOS/PRISM) was essential for accurately detecting small deformations. The vertical displacement rate during the investigated period (2007–2010) was estimated to be −28 mm. The results further indicate that the northern area of Port-Said City has been subjected to higher land subsidence rates compared to the southern area. Such land subsidence rates might induce significant environmental changes with respect to sea-level rise.

Assessing Efficiency of Service Quality on Consumers Retention in Nigerian Mobile Service Industry

This study examines the influence of service quality on retention through a mediating effect of customer satisfaction in the Nigerian mobile services industry. Based on a survey of 203 undergraduate students, questionnaires administered were analysed using SPSS statistical software to test the stated hypotheses. Findings revealed that innovativeness, technological competence and customer responsiveness have significant positive effect on customer retention. However, innovation was found to have more effect on satisfaction. Results also revealed that the effect of service quality dimensions on students’ retention of mobile services is partially mediated by their satisfaction. This study recommended that organizations should design and implement appropriate service quality strategies capable of satisfying changing customers’ needs and preferences.

Real Machines Design Choices / Engineering Trade-Offs

T his special issue addresses the business of producing computing machines and the choices computer architects and implementors must make to succeed in the marketplace. This focus represents the sober reflection that computer architecture is not yet a science, even though parts of the discipline can be considered science and most of it often involves scientific methodology. To a large extent, the field is not driven by an interest in finding order in what appears to be chaos, but rather by an interest in producing a product that people will buy. To produce that product, architects and implementors have a budget, whether measured in dollars, gates, person-years, or similar entities, with which to achieve a certain functional capability at a specified performance level. Within those constraints, many choices are available. This issue of Computer examines these choices within the context of specific machine designs. Some of these choices and a framework for their consideration are identified below.
Coercion as Proof Search in Dependent Type Semantics

This paper presents an analysis of coercion and related phenomena in the framework of Dependent Type Semantics (DTS). Using underspecified terms in DTS, we present an analysis of selectional restriction as presupposition; we then combine it with a type called ‘transfer frame’ to provide an analysis of coercion. Our analysis focuses on the fact that coercion is triggered not only by type mismatch between predicates and their arguments, but also by more general inference with contextual information. We show how the analysis can be extended to copredication of logical polysemy and complement coercion. Finally, we will suggest that this analysis can shed light on an aspect of complicity that is invoked in interpreting coercion and other meaning-shifting phenomena.
Le génome du cacaoyer : du décodage de sa séquence jusqu'à l'étude des gènes impliqués dans des caractères agronomiques d'intérêt

Depuis plusieurs annees, les programmes de recherche chez le cacaoyer ont mis l'accent sur l'etude des bases genetiques des caracteres agronomiques d'interet, notamment concernant la resistance aux maladies et la qualite des feves de cacao, qui representent deux attributs importants pour la cacaoculture et la production de chocolat. Ce travail presente, par l'exploration du transcriptome et du genome du cacaoyer, la constitution de ressources moleculaires et l'analyse des voies de biosynthese impliquees dans plusieurs de ces caracteres agronomiques d'interet. L'etude du transcriptome a permis l'identification de plusieurs dizaines de milliers de genes exprimes dans divers organes et pour differentes conditions environnementales et ont fourni de nombreux marqueurs moleculaires qui ont ete utilises pour realiser des cartes genetiques haute densite. Les informations apportees par ce travail ont permis d’engager le sequencage du genome de la variete Criollo du cacaoyer. Son analyse et son annotation ont apporte un ensemble d'informations biologiques cruciales, depuis le catalogue des genes et elements mobiles jusqu'aux aspects evolutifs qui a revele une structure du genome peu remanie par rapport a l'ancetre commun aux dicotyledones. Par la suite, les travaux que nous avons menes pour ameliorer la sequence complete ont conduit a une reduction considerable de la fragmentation chromosomique observee dans la premiere version. Par ailleurs 97% de la sequence assemblee et 99% des genes sont desormais ancres sur les chromosomes du cacaoyer. Pour commencer a exploiter cette nouvelle sequence du genome, nous avons conduit une etude QTL a partir d'une descendance entre Trinitario implantee en Guyane, permettant de localiser les regions genomiques impliquees dans la variation de la couleur des feves de cacao. En s'appuyant sur la version amelioree du genome du Criollo, nous avons identifie deux genes potentiellement impliques dans la voie de biosynthese des anthocyanines et flavonoides dans la principale region genomique concernee. Un des deux genes, situe proche du marqueur situe au pic du QTL et codant pour une chalcone synthase, semble etre un gene candidat prometteur. L'etude comparative de sa structure dans le genome du Criollo (a feve blanche) et du genome de l'Amelonado (a feve violette) a mis en evidence des differences structurales pouvant etre a l'origine d'une modification fonctionnelle. L'ensemble des resultats presentes dans ce travail de these apporte une connaissance et des outils varies qui peuvent etre exploites par de multiples approches integrees pour etudier la genetique du cacaoyer.
Transcriptome and proteome responses in RNAlater preserved tissue of Arabidopsis thaliana

Tissue preservation is a minimal requirement for the success of plant RNA and protein expression studies. The standard of snap-freezing in liquid nitrogen is not always practical or possible. RNAlater, a concentrated solution of ammonium and cesium sulfates, has become a standard preservative in the absence of liquid nitrogen. Here, we demonstrate the effectiveness of RNAlater in preserving both RNA and proteins in Arabidopsis thaliana tissues for use in RNAseq and LC-MS/MS analysis of proteins. While successful in preserving plant material, a transcriptomic and proteomic response is evident. Specifically, 5770 gene transcripts, 84 soluble proteins, and 120 membrane-bound proteins were found to be differentially expressed at a log-fold change of ±1 (P ≤ 0.05). This response is mirrored in the abundance of post-translational modifications, with 23 of the 108 (21.3%) phosphorylated proteins showing altered abundance at a log-fold change of ±1 (P ≤ 0.05). While RNAlater is effective in preserving biological information, our findings warrant caution in its use for transcriptomic and proteomic experiments.
P.70 pertactin, an outer‐membrane protein from Bordetella parapertussis: cloning, nucleotide sequence and surface expression in Escherichia coli

The gene prn encoding the outer‐membrane protein P.70 (pertactin) from Bordetella parapertussis has been cloned in Escherichia coli and its DNA sequence determined. Analysis of the DNA sequence reveals that the gene has an open reading frame comprising 922 amino acids capable of encoding a protein with a molecular weight of 95177 (P.95). In vivo processing of this precursor yields a protein with an estimated Mr of 70kDa (P.70) which is located on the surface of B. parapertussis. Homology between the prn gene from B. parapertussis and that from Bordetella pertussis is 91.3%. The homology is 93% when the protein sequence of P.95 is aligned with that of P.93 from B. pertussis. The major differences between the P.70 pertactin from B. parapertussis and the P.69 pertactin from B. pertussis occur in the number of reiterated units within the repeat motifs found in both proteins; the sequence Gly–Gly–Xaa–Xaa–Pro is repeated four times in the P.70 pertactin, and five times in the P.69 pertactin, while the sequence Pro–Gln–Pro occurs nine times in P.70 pertactin and five times in P.69 pertactin. Cloning of the gene for P.95 in an E. coli expression vector results in the synthesis of a protein that mimics native gene expression in B. parapertussis, i.e. the P.95 protein is synthesized and subsequently processed to yield the P.70 form of the protein on the surface of the cell.
Leptin and Leptin Receptor Expression in Rat and Mouse Pituitary Cells1.

Leptin is a circulating hormone secreted mainly by adipose tissue. Recent studies have shown leptin production by other tissues, including the placenta, stomach, and mammary tissues. Various reports have suggested that the anterior pituitary may have a role in the regulatory effects of leptin. We recently localized leptin in the human anterior pituitary, but analysis of leptin in rodent pituitary has not been previously reported. In this study we examined rat and mouse pituitary tissues and various cell lines for leptin by RT-PCR, immunohistochemistry, and Western blotting. Leptin receptor messenger RNA was also examined in these tissues by RT-PCR. Leptin was present in a small percentage of rat (4.8 ± 0.7%) and mouse (7 ± 2%) pituitary cells. Colocalization studies with leptin and pituitary hormones showed leptin expression mainly in TSH cells (24 ± 2% of TSH cells in the rat pituitary and 31 ± 1% of TSH cells in the mouse pituitary). A folliculo-stellate (FS) cell line, TtT/GF, also expressed leptin. Th.
A Laser Based Fusion Test Facility

Abstract The Fusion Test Facility (FTF) is a high repetition rate ignition facility that would bridge the gap between single shot facilities (such as NIF and LMJ) and a fully functioning laser fusion power plant. It would allow development of science and technologies so that follow-on power plants could have predictable performance. The FTF would need to have enough fusion power, about 100 MW, to rigorously test materials and components for the power plants. Because inertial fusion provides a “point” source for neutrons, it can provide very high fluxes for test objects placed close to the target, while the reaction chamber walls remain at conservatively large distances. Simulations indicate that direct-drive designs can achieve 100 MW fusion power with laser energies well below 1 MJ with a 5 Hz driver. High-resolution 2-D simulations of high-velocity direct-drive implosions utilizing a Krypton-Fluoride (KrF) laser give gains of >60× at 500 kJ, and shock-ignited targets may allow higher gains at even lower driver energy. Utilizing designs that require relatively small driver energy is the most straightforward path to reducing cost and development time for a practical laser fusion energy power plant. A program to develop an FTF would build upon the science and technologies developed in the existing National Ignition Campaign and the High Average Power Laser (HAPL) program, as well as the magnetic fusion technology program.
Pulmonary Immunotoxicology of Select Metals: Aluminum, Arsenic, Cadmium, Chromium, Copper, Manganese, Nickel, Vanadium, and Zinc

INTRODUCTION The field of immunotoxicology had its inception in the early 1970s; the science of pulmonary toxicology has been recognized for more than forty years. With increasing research efforts in both fields, a convergence of the two in the quest to understand how inhalation of toxic agents can alter the health of a host was inevitable. In general, the majority of the advances in our understanding of pulmonary immunotoxicology have come as the result of studies in humans or animal models that inhaled or were instilled with toxicants. Still, it needs to be emphasized that immunomodulation in the lungs can also be caused by agents that enter the body by non-respiratory routes and that all agents are not necessarily immunomodulatory. Pulmonary immunotoxicologic research over the past decade has been increasingly important in elucidating how exactly workplace/environmental agents can cause those changes in immunologic function in the lungs that allow for indirect alterations in respiratory health and, subsequently, the overall health of exposed individuals. The purpose of this review is to provide information about how our understanding of the pulmonary immunotoxicology of select inorganic agents, i.e., metals, has evolved over the past ≈30+ years. Specifically, the review covers the literature to date dealing with aluminum, arsenic, cadmium, chromium, copper, manganese, nickel, vanadium, and zinc, in each of their various inorganic forms with differing chemistries, sizes, and solubilities. For each metal, information regarding occupational and environmental levels that are readily encountered, as well as permissible levels of exposure (when information was available), is presented at the outset. Thereafter, specific effects on humoral, cell-mediated, and innate immune functions, and potential overall effects within the lungs (i.e., as
Probability models for information retrieval based on divergence from randomness

This thesis devises a novel methodology based on probability theory, suitable for the construction of term-weighting models of Information Retrieval. Our term-weighting functions are created within a general framework made up of three components. Each of the three components is built independently from the others. We obtain the term-weighting functions from the general model in a purely theoretic way instantiating each component with different probability distribution forms. The thesis begins with investigating the nature of the statistical inference involved in Information Retrieval. We explore the estimation problem underlying the process of sampling. De Finetti’s theorem is used to show how to convert the frequentist approach into Bayesian inference and we display and employ the derived estimation techniques in the context of Information Retrieval. We initially pay a great attention to the construction of the basic sample spaces of Information Retrieval. The notion of single or multiple sampling from different populations in the context of Information Retrieval is extensively discussed and used through-out the thesis. The language modelling approach and the standard probabilistic model are studied under the same foundational view and are experimentally compared to the divergence-from-randomness approach. In revisiting the main information retrieval models in the literature, we show that even language modelling approach can be exploited to assign term-frequency normalization to the models of divergence from randomness. We finally introduce a novel framework for the query expansion. This framework is based on the models of divergence-from-randomness and it can be applied to arbitrary models of IR, divergence-based, language modelling and probabilistic models included. We have done a very large number of experiment and results show that the framework generates highly effective Information Retrieval models.
Real-time perfusion echocardiography during treadmill exercise and dobutamine stress testing

Background Real-time perfusion (RTP) echocardiographic imaging with a continuous infusion of microbubbles has improved the sensitivity of dobutamine stress echocardiography (DSE) in detecting coronary artery disease (CAD). The impact of RTP on treadmill exercise stress echocardiography (TESE) is unclear. Design Retrospective database review. Setting/patients/interventions RTP was utilised in 254 DSE and TESE patients being examined for the presence of significant CAD. A continuous infusion of 3% Definity (Lantheus Medical Imaging) was used for all studies, and contrast replenishment (MCR), plateau intensity (PMCE) and wall motion (WM) were examined for the detection of CAD. Main outcome measures Sensitivity/specificity/accuracy to detect CAD. Results For DSE, the sensitivity of myocardial perfusion (MP) imaging with RTP was 85%, which was significantly higher than WM analysis (72%; p<0.05). The improvement in sensitivity with MP analysis during DSE was primarily the result of better detection of left anterior descending disease. MP sensitivity during TESE was significantly better than MP sensitivity during DSE (98% versus 85%; p<0.05), and WM sensitivity during TESE was better than WM sensitivity during DSE (89% versus 72%; p<0.05). The improvement in WM sensitivity during TESE was due to detection of subendocardial wall thickening abnormalities in 48% of the patients with induced subendocardial perfusion defects. Conclusion Myocardial perfusion imaging with RTP improves the detection of CAD during both DSE and TESE. During TESE, the subendocardial perfusion defects improve WM sensitivity by delineating subendocardial WM abnormalities.
