An Improved Combined Content-similarity Approach for Optimizing Web Query Disambiguation

The web search engines are exposed to the issue of uncertainty because of ambiguous queries, being input for retrieving the accurate results. Ambiguous queries constitute a significant fraction of such instances and pose real challenges to web search engines. Moreover, web search has created an interest for the researchers to deal with search by considering context in terms of location perspective. Our proposed disambiguation approach is designed to improve user experience by using context in terms of location relevance with the document relevance. The aim is that providing the user a comprehensive location perspective of a topic is informative than retrieving a result that only contains temporal or context information. The capacity to use this information in a location manner can be, from a user perspective, potentially useful for several tasks, including user query understanding or clustering based on location. In order to carry out the approach, we developed a Java based prototype to derive the contextual information from the web results based on the queries from the well-known datasets. Among those results, queries are further classified in order to perform search in a broad way. After the result provision to users and the selection made by them, feedback is recorded implicitly to improve the web search based on contextual information. The experiment results demonstrate the outstanding performance of our approach in terms of precision 75%, accuracy 73%; recall 81% and f-measure 78% when compared with generic temporal evaluation approach and furthermore achieved precision 86%, accuracy 71%; recall 67% and f-measure 75% when compared with web document clustering approach.

Spatial and temporal variations of tintinnids (Ciliata: Protozoa) in the Bay of Mersin, Northeastern Mediterranean Sea

Seasonal variations in species composition and abundance of tintinnids were investigated in the eutrophic coastal and offshore waters of Mersin Bay. Twelve sampling cruises were performed from September 2008 to February 2011. A total of 85 tintinnid taxa were identified. Among the recorded genera, agglutinated Tintinnopsis had the largest number of species (12 species), followed by hyaline loricated Eutintinnius (9 species), and Proplectella (7 species). Stenosemella ventricosa, Tintinnopsis beroidea, T. compressa, Favella azorica, and Helicostemella subulata were the dominant species during the study period. There were clear seasonal variations in species composition and abundance of tintinnids. The highest number of tintinnid species occurred in January 2009 and November 2010 in the entire study area, while the lowest species number occurred in March 2009. Morever, species numbers were higher in offshore stations than coastal stations. Some species were present in the coastal area of the bay, and other species were present offshore. The highest tintinnid abundance values were found in September 2008 (820 ind L-1) and August 2009 (749 ind L-1) at coastal stations. The high abundance values in the coastal stations indicates that an increase of tintinnids is closely related to trophic status of the marine environment. In connection with these results, correlation analysis revealed that chlorophyll-a had an important effect on tintinnid abundance. Tintinnid communities may be used as a potential bio-indicator for assessing the trophic state of the coastal seas and bays.

A Control Strategy of Modular Multilevel Converter with Integrated Battery Energy Storage System Based on Battery Side Capacitor Voltage Control

A modular multilevel converter with an integrated battery energy storage system (MMC-BESS) has been proposed for high-voltage applications for large-scale renewable energy resources. As capacitor voltage balance is key to the normal operation of the system, the conventional control strategy for the MMC can be significantly simplified by controlling the individual capacitor voltage through a battery side converter in the MMC-BESS. However, the control strategy of the MMC-BESS under rectifier mode operation has not yet been addressed, where the conventional control strategy cannot be directly employed due to the additional power flow of batteries. For this defect, the rectifier mode operation of the MMC-BESS based on a battery side capacitor voltage control was analyzed in this paper, proposing a control strategy for this application scenario according to the equivalent circuit of MMC-BESS, avoiding passive impact on the state-of-charge (SOC) equalization of batteries. Furthermore, the implementation of a battery side converter control is proposed by simplifying the capacitor voltage filter scheme within phase arm, which enhances its performance and facilitates the realization of control strategy. Finally, simulation and experimental results validate the feasibility and effectiveness of the proposed control strategy.
A Novel On-Glass GPS Antenna for Handset Applications

Abstract In this paper, we propose a novel on-glass antenna with a planar structure for the GPS wireless communication. A prototype of the proposed antenna with a compact size of 6mm×18 mm is experimented in the mobile handset operation. The antenna shows operating bandwidths (referenced Return loss -6 dB) for covering the GPS L1 band in 1.575 GHz. The present design mainly focuses on the current trends in the development of compact and low profile mobile handset. For reducing the dimension of the antenna area in the device, the GPS antenna is placed on the inner surface of the glass over the display. Moreover, the antenna design can be against to avoid the degradation in the user handheld condition. The simulated and measured data including return loss, antenna gain and radiation patterns are presented. As a result of the measurement, the antenna design is proper to the GPS band application in the mobile handset.
RanGTP induces an effector gradient of XCTK2 and importin α/β for spindle microtubule cross-linking

High RanGTP around chromatin is important for governing spindle assembly during meiosis and mitosis by releasing the inhibitory effects of importin α/β. Here we examine how the Ran gradient regulates Kinesin-14 function to control spindle organization. We show that Xenopus Kinesin-14, XCTK2, and importin α/β form an effector gradient, which is highest at the poles that diminishes toward the chromatin and is inverse of the RanGTP gradient. Importin α/β preferentially inhibit XCTK2 anti-parallel microtubule cross-linking and sliding by decreasing the microtubule affinity of the XCTK2 tail domain. This change in microtubule affinity enables RanGTP to target endogenous XCTK2 to the spindle. We propose that these combined actions of the Ran pathway are critical to promote Kinesin-14 parallel microtubule cross-linking at the spindle poles to cluster centrosomes in cancer cells. Furthermore, our work illustrates that RanGTP regulation in the spindle is not simply a switch, but rather generates effector gradients where RanGTP gradually tunes the activities of spindle assembly factors. Summary Ems-McClung et al. visualize a RanGTP effector gradient of association between XCTK2 and importin α/β in the spindle. The importins preferentially inhibit XCTK2-mediate anti-parallel microtubule cross-linking and sliding, which allows XCTK2 to cross-link parallel microtubules and help focus spindle poles.
STRUCTURAL STUDIES ON LIGAND AND LIPID MODULATION OF THE CAPSAICIN RECEPTOR, TRPV1

Author(s): Gao, Yuan | Advisor(s): Edwards, Robert | Abstract: When integral membrane proteins are visualized in detergents or other artificial systems, an important layer of information is lost regarding lipid interactions and their effects on protein structure. This is especially relevant to proteins for which lipids play both structural and regulatory roles. Here, we demonstrate the power of combining electron cryo-microscopy with lipid nanodisc technology to ascertain the structure of an integral membrane protein - the TRPV1 ion channel - in a native bilayer environment. Using this approach, we could ascertain the locations of annular and regulatory lipids, enabling us to show that specific phospholipid interactions enhance binding of a spider toxin to TRPV1 through formation of a tripartite complex. Furthermore, phosphatidylinositol lipids occupy the binding site for capsaicin and other vanilloid ligands, suggesting a mechanism whereby chemical or thermal stimuli elicit channel activation by promoting release of bioactive lipids from a critical allosteric regulatory site.
The impact evaluation of public health insurance in Indonesia on access to care, financial protection, and health status

Objectives This study evaluates the impact of an expanded national health insurance programme in Indonesia, focusing on three outcomes: access to health care, as measured by utilisation of health care services; financial protection, as measured by out-of-pocket (OOP) health expenditure and catastrophic health expenditure (CHE) indicators; and health status, as measured by levels of blood pressure and rates of diagnosed, treated and controlled hypertension. Research Methods This study uses longitudinal data from the Indonesian Family Life Survey (IFLS) collected from 13 Indonesia’s provinces, a total of 22,711 adults in 2007 who were followed up in 2014. The JKN enrolees are categorised into two groups: a contributory group who paid the premium voluntarily, and a subsidised group, paid by government. Each group is compared with the uninsured group who had no insurance coverage in both 2007 and 2014. Propensity score matching combined with difference-in-difference approaches are used to estimate the causal effect of the JKN programme. Heterogeneity of the effects of JKN is explored based on socioeconomic status, locality of residence (urban/rural), and availability of health facilities in the area. Results The JKN programme increased the probability of individuals in the contributory group seeking outpatient and inpatient care as well as the volume of care provided. The subsidised group also showed increased utilisation, but the magnitude of the effect is much smaller than in the contributory group. In relation to financial protection, the JKN programme had no statistically significant effect on OOP health expenditure or catastrophic health expenditure. In terms of health outcomes, while the programme had no significant effect on systolic or diastolic blood pressure, the data suggest a positive effect on increasing awareness and treatment of hypertension among the contributory group and, to a lesser extent, the subsidised group. Conclusions The JKN programme encouraged individuals in the contributory group to use more medical treatment, which had no effect, on average, on their health expenditure. The subsidised group appears not to have been able to maximise the JKN benefit, possibly due to other barriers in access to care, such as the inadequate supply of health facilities. The impact of the JKN programme on health status is yet to be confirmed as sufficient time has not passed for the programme’s effect on health status to be realised
A Run Lenght Smooting-Based Algorithm For Non-Manhattan Document Segmentation

Layout analysis is a fundamental step in automatic document processing, because its outcome affects all subsequent processing steps. Many different techniques have been proposed to perform this task. In this work, we propose a general bottom-up strategy to tackle the layout analysis of (possibly) non-Manhattan documents, and two specializations of it to handle both bitmap and PS/PDF sources. A famous approach proposed in the literature for layout analysis was the RLSA. Here we consider a variant of RLSA, called RLSO (short for “RunLengh Smoothing with OR”), that exploits the OR logical operator instead of the AND and is particularly indicated for the identification of frames in nonManhattan layouts. Like RLSA, RLSO is based on thresholds, but based on different criteria than those that work in RLSA. Since setting such thresholds is a hard and unnatural task for (even expert) users, and no single threshold can fit all documents, we developed a technique to automatically define such thresholds for each specific document, based on the distribution of spacing therein. Application on selected sample documents, that cover a significant landscape of real cases, revealed that the approach is satisfactory for documents characterized by the use of a uniform text font size.
Validation of Messaâdi equation on viscosity-temperature dependence for some ternary liquid mixtures by statistical correlation analysis

ABSTRACT The analysis of viscosity of fluid systems is in great demand by the optimisation of industrial products and processes. For this instance, numerous empirical expressions have been suggested in the literature to treat and investigate the viscosity of pure, binary and ternary solvents mixtures. In this circumstance, an interesting empirical equation correlating the two parameters related to the viscosity Arrhenius-type equation has recently proposed by Messaâdi et al. for some pure solvents and binary liquid mixtures. This work attempts to extend their equation to ternary liquid systems. Statistical analysis is made to perform this aim by utilising 113 data sets from previous works of some ternary solvents systems at different compositions. The validation of the generalised Messaâdi expression for ternary liquid systems oversimplifies the prediction of shear viscous behaviour as well as the estimation of one non-disposable parameter value when only the second one is present in literature.
An efficient 5-axis toolpath optimization algorithm for machining parts with abrupt curvature

The kinematical behavior of 5-axis machine tool introduced by toolpath calculation has a close relation with processing efficiency and quality of parts. For the category of sculptured surface parts with abrupt curvature, such as turbine blade and fixed guide vane, the most commonly utilized spiral contouring toolpath modes usually encounter some trouble during actual machining, the reason lies in the difficult tool orientation control near the edge of such parts. However, the global optimization for the spiral toolpath means increased computation burden, and so it is time consuming. In this paper, an efficient 5-axis toolpath optimization algorithm is presented, and the objective is to smooth the rotary axes’ motion caused by drastically changed tool orientation on spiral toolpath for abrupt curvature parts machining. To reduce the computation burden, only path segments on the spiral trajectory-owned weak kinematic performance are selected for further optimizing. To obtain smoother motion for rotary axes, the specific optimization computation for the selected path segments is conducted in the Machine Coordinate System (MCS) instead of the Part Coordinate System (PCS). The optimization model is constructed and a related solution method is presented to ensure the high-performance optimization. The complete optimization algorithm is demonstrated on a spiral 5-axis toolpath for the turbine blade finish machining, and the result shows that only 25.9% optimization computation is needed compared with global optimization algorithm. And then, the actual machining experiments are carried out by using paraffin as cut material, and the machining time with optimized toolpath is decreased by 19.7% compared with initial toolpath. In addition, the surface quality of parts is significantly improved after conducting the optimization. This study proves that the proposed algorithm can significantly improve the processing efficiency and surface quality of parts with abrupt curvature and provides an efficient method to optimize the spiral 5-axis toolpath used for finish machining parts with abrupt curvature.

Inferring Aspect-Specific Opinion Structure in Product Reviews

Identifying differing opinions on a given topic as expressed by multiple people (as in a set of wrien reviews for a given product, for example) presents challenges. Opinions about a particular subject are oen nuanced: a person may have both negative and positive opinions about different aspects of the subject of interest, and these aspect-specific opinions can be independent of the overall opinion on the subject. Being able to identify, collect, and count these nuanced opinions in a large set of data offers more insight into the strengths and weaknesses of competing products and services than does aggregating the overall ratings of such products and services. I make two useful and useable contributions in working with opinionated text. First, I presentmy implementation of a semi-supervised co-trainingmachine classification method for identifying both product aspects (features of products) and sentiments expressed about such aspects. It offers beer precision than fully-supervised methods while requiring much less text to be manually tagged (a time-consuming process). is algorithm can also be run in a fully supervised manner when more data is available. Second, I apply this co-training approach to reviews of restaurants and various electronic devices; such text contains both factual statements and opinions about features/aspects of products. e algorithm automatically identifies the product aspects and the words that indicate aspect-specific opinion polarity, while largely avoiding the problem of misclassifying the products themselves as inherently positive or negative. is method performs well compared to other approaches. When run on a set of reviews of five technology products collected from Amazon, the system performed with some demonstrated competence (with an average precision of 0.83) at the difficult task of simultaneously identifying aspects and sentiments, though comparison to contemporaries’ simpler rules-based approaches was difficult. When run on a set of opinionated sentences about laptops and restaurants that formed the basis of a shared challenge in the SemEval-2014 Task 4 competition, it was able to classify the sentiments expressed about aspects of laptops beer than any team that competed in the task (achieving 0.72 accuracy). It was above the mean in its ability to identify the aspects of restaurants about which people expressed opinions, even when co-training using only half of the labelled training data at the outset. While the SemEval-2014 aspect-based sentiment extraction task considered only separately the tasks of identifying product aspects and determining their polarities, I take an extra step and evaluate sentences as a whole, inferring aspects and the aspect-specific sentiments expressed simultaneously, amore difficult task that seemsmore applicable to real-world tasks. I present first results of this sentence-level task.
Management of Biloma due to Biliary Tract Injury after Laparoscopic Cholecystectomy in a patient with Atypical Anatomy: A Case Report

Introduction: Biliary tract injury is a major complication of laparoscopic cholecystectomywhich can be very challenging. But, the important part is to know the accurate anatomy of the ducts and site of the injury before any surgical attempt for ligation or repair. In this case a disaster might happen if we do not consider biliary anatomical abnormality as the main issue. Case Report In this case, there was an additional duct originating from the right hepatic lobe and inserting directly to the common bile duct (CBD) along with the right hepatic duct. The injury to this branch led to biloma secretion from two tearing sites, one proximal to the branch and another distal of the branch adjacent to CBD, during laparoscopic cholecystectomy. Conclusion There are numerous anatomic variations in the biliary tract, so according to this case we highly recommend to assay the exact anatomy before any intervention by means of Magnetic resonance cholangiopancreatography (MRCP) or intraoperative cholangiography.
