Discovering the best web service

Major research challenges in discovering Web services include, provisioning of services across multiple or heterogeneous registries, differentiating between services that share similar functionalities, improving end-to-end Quality of Service (QoS), and enabling clients to customize the discovery process. Proliferation and interoperability of this multitude of Web services have lead to the emergence of new standards on how services can be published, discovered, or used (i.e. UDDI, WSDL, SOAP). Such standards can potentially provide many of these features and much more, however, there are technical challenges associated with existing standards. One of these challenges is the client.s ability to control the discovery process across accessible service registries for finding services of interest. This work proposes a solution to this problem and introduces the Web Service Relevancy Function (WsRF) used for measuring the relevancy ranking of a particular Web service based on QoS metrics and client preferences. We present experimental validation, results, and analysis of the presented ideas.
Experimental Demonstration of Non-Stateful In-Memory Logic With 1T1R OxRAM Valence Change Mechanism Memristors

Processing-in-memory (PIM) is attractive to overcome the limitations of modern computing systems. Numerous PIM systems exist, varying by the technologies and logic techniques used. Successful operation of specific logic functions is crucial for effective processing-in-memory. Memristive non-stateful logic techniques are compatible with CMOS logic and can be integrated into a 1T1R memory array, similar to commercial RRAM products. This brief analyzes and demonstrates two non-stateful logic techniques: 1T1R logic and scouting logic. As a first step, the used 1T1R SiOx valence change mechanism memristors are characterized in reference to their feasibility to perform logic functions. Various logical functions of the two logic techniques are experimentally demonstrated, showing correct functionality in all cases. Following the results, the challenges and limitations of the RRAM characteristics and 1T1R configuration for the application in logical functions are discussed.
World Mangrove Atlas

The World Mangrove Atlas provides an overview of the distribution of mangroves worldwide. Mapped data were gathered from a wide range of sources and were synthesized into a series of 25 regional maps. Related texts describing the species geographic extent and other summary information on the status of mangroves in each country are provided. A number of case studies demonstrate what can be achieved using greater resolution and much more detailed investigation. They show mangroves growing in very different conditions such as estuaries deltas lagoons wet tropical coasts and arid coasts. They also illustrate a range of different mapping techniques and provide detail on some of the issues threatening mangroves worldwide. The atlas is intended for scientists politicians planners conservationists and others who have an interest in the status and future of mangroves. For people interested in the extent and dynamics of mangroves this atlas can provide a well-documented foundation from which to start explorations.
Improved Approximations for Ordered TSP on Near-Metric Graphs: Extended Abstract

The traveling salesman problem with precedence constraints is one of the most important problems in operations research. Here, we consider the well-known variant where a linear order on k special vertices is given that has to be preserved in any feasible Hamiltonian cycle. This problem is called Ordered TSP and we consider it on input instances where the edge-cost function satisfies a β-relaxed triangle inequality, i. e. , where the length of a direct edge cannot exceed the cost of any detour via a third vertex by more than a factor of β > 1. We design two new polynomial-time approximation algorithms for this problems. The first algorithm essentially improves over the best previously known algorithm for almost all values of k and β < 1.12651. The second algorithm gives a further improvement for 2n ≥ 11k + 7 and β < 2/ √ 3, where n is the number of vertices in the graph.
Collateral sensitivity of σ2 receptors ligands: potentials in the treatment of multidrug resistant tumors.

Tumors remain one of the main causes of human illnesses and death with MultiDrug Resistance (MDR) being the most severe limitation to the success of chemotherapy. MDR is mainly due to the overexpression of drug efflux transporters, such as P-glycoprotein (P-gp), but attempts to inhibit P-gp have not been clinically successful so far. Lately, some agents were found to be more effective against P-gp overexpressing cells, showing a property termed “collateral sensitivity” (CS). The molecular bases of CS are poorly understood and hypersensitivity to reactive oxygen species (ROS) is one of the hypotheses that accounts for it. We recently identified a few sigma-2 ( σ 2 ) receptors ligands endowed with CS, likely because of their interaction with P-gp. In fact, a number of CS agents are P-gp substrates: they are actively effluxed by P-gp, and it is believed that they activate a futile ATP cycle, increase oxidative phosphorylation leading to higher ROS production and oxidative stress. Therefore, we verified ROS involvement to study the CS properties of σ 2 receptors ligands/P-gp substrates ( F408 and siramesine) whose activity was measured in three parental and Pg-p-overexpressing cell line pairs. We also demonstrated the major consumption of ATP induced by these compounds in P-gp overexpressing vs the parental cells. We analyzed the effects of siramesine and F408 on mitochondrial respiratory chain (source of ROS and intracellular ATP). Siramesine and F408 decreased both the electron flux rate and the ATP levels, with MDR cells undergoing a much more pronounced decrease than parent cells. Therefore, we demonstrated depletion of mitochondrial ATP supply by siramesine and F408 as the mechanism by which these σ 2 ligands likely induce CS. In conclusion, CS and σ 2 ligands-mediated actions warrant further investigation as a way to face MDR.
Brain-Inspired Mutual Synchronization in Cross-Coupled NbOx Oscillation Neurons for Oscillatory Neural Network Applications

The brain performs cognitive functions through rhythmic communications of neural oscillations across numerous spatially distributed neurons. This process is known as “binding by synchrony”. Herein, we demonstrate oscillatory neural networks (ONNs) based on a nanoscale NbOx device for compact oscillation neurons (ONs). When a voltage (VDD) is applied to the NbOx-based device, a high resistance state is temporarily changed to a low resistance state due to the formation of a conducting path. Owing to the volatile switching characteristics, the VDD across the NbOx device, serially connected with an additional load resistor (RL), is repeatedly increased and decreased, generating oscillations at the intermediate node. We experimentally investigated the impact of RL and VDD on the oscillation behavior of the single ON circuit. Thereafter, through simulations, we analyzed the interactions between the voltage oscillations when two NbOx-based ONs were connected by a coupling element (e.g., variable resistor or capacitor). The results showed that the oscillations were either in- or out-of-phase synchronized owing to the coupling strength. These two distinguishable synchronizations can be used to encode binary information in the phase domain, resulting in energy-efficient computing. This study proves that by building ONNs comprising multiple ONs, both sharp edges and pretrained patterns can be detected from images.
MATHEMATICAL AND NUMERICAL MODELLING OF GAS-SOLID TURBULENT FLOWS IN COMPLEX GEOMETRIES

The presence of solid particles in industrial turbulent flows in complex geometries is widely evidenced in engineering. However the correct prediction of flow patterns, particles trajectories and distributions is a highly complex task. The analysis of the particle velocity as well as their trajectories in the gas-solid flow is of fundamental importance. We used an Euler-Lagrangean approach where the dispersed phase is treated in the Lagrangean referential and the governing equations for the continuous phase are solved in the Eulerian referential. An advantage of the application of the Immersed Boundary Method is that the immersed geometry is also represented in the Lagrangean referential. It is worthy to recall that one of the advantages of the Immersed boundary methodoly is the capability of solving flows in the presence of complexes geometries in Cartesian grids, which facilitates the particle tracking of solid particles in LES. By performing Large Eddy Simulations we demonstrate, in the present work, that it is possible to predict complex multiphase flows by combining promising methodologies like LES and Immersed Boundary Methodology. The fully parallel in-house code developed was validated face to experimental results of Sommerfeld and S.Lain (2001) with very good accuracy.

Mathematical Modelling and Numerical Analysis Spectral Galerkin Approximation of Fokker–planck Equations with Unbounded Drift

This paper is concerned with the analysis and implementation of spectral Galerkin methods for a class of Fokker–Planck equations that arises from the kinetic theory of dilute polymers. A relevant feature of the class of equations under consideration from the viewpoint of mathematical analysis and numerical approximation is the presence of an unbounded drift coefficient, involving a smooth convex potential U that is equal to +∞ along the boundary ∂D of the computational domain D. Using a symmetrization of the differential operator based on the Maxwellian M corresponding to U , which vanishes along ∂D, we remove the unbounded drift coefficient at the expense of introducing a degeneracy, through M , in the principal part of the operator. The general class of admissible potentials considered includes the FENE (finitely extendible nonlinear elastic) model. We show the existence of weak solutions to the initial-boundary-value problem, and develop a fully-discrete spectral Galerkin method for such degenerate Fokker–Planck equations that exhibits optimal-order convergence in the Maxwellian-weighted H 1 norm on D. In the case of the FENE model, we also discuss variants of these analytical results when the Fokker–Planck equation is subjected to an alternative class of transformations proposed byChauvì ere & Lozinski; these map the original Fokker–Planck operator with an unbounded drift coefficient into Fokker–Planck operators with unbounded drift and reaction coefficients, that have improved coercivity properties in comparison with the original operator. The analytical results are illustrated by numerical experiments for the FENE model in two space dimensions. The dates will be set by the publisher.
A Review on the Methods for Observing the Substance and Energy Exchange between Atmosphere Boundary Layer and Free Troposphere

Atmosphere boundary layer (ABL or BL) acts as a pivotal part in the climate by regulating the vertical exchange of moisture, aerosol, trace gases and energy between the earth surface and free troposphere (FT). However, compared with research on the exchange between earth surface and ABL, there are fewer researches on the exchange between ABL and FT, especially when it comes to the quantitative measurement of vertical exchange flux between them. In this paper, a number of various methodologies for investigating the exchange of the substance and energy between ABL and FT are reviewed as follows: (1) methods to obtain entrainment rate, which include method by investigating the height of inversion layer, method of flux-jump, estimating with dataset from the ASTEX Lagrangian Experiments and method of using satellite observations and Microwave Imager; (2) mass budget method, which can yield quantitative measurements of exchange flux between ABL and FT; (3) qualitative measurements: method based on Rayleigh distillation and mixing processes, methods of ground-based remote sensing and airborne tracer-tracer relationship/ratio method.
Children of the Land: Adversity and Success in Rural America. Studies on Successful Adolescent Development.

A century ago, most Americans had ties to the land. Now only one in fifty is engaged in farming and little more than a fourth live in rural communities. Though not new, this exodus from the land represents one of the great social movements of our age and is also symptomatic of an unparalleled transformation of our society. In "Children of the Land", the authors ask whether traditional observations about farm families - strong intergenerational ties, productive roles for youth in work and social leadership, dedicated parents and a network of positive engagement in church, school and community life - apply to 300 Iowa children who have grown up with some tie to the land. The answer, as this study shows, is a resounding yes. In spite of the hardships they faced during the agricultural crisis of the 1980s, these children, whose lives we follow from the 7th grade to after high school graduation, proved to be remarkably successful, both academically and socially. A moving testament to the distinctly positive lifestyle of Iowa families with connections to the land, this book also suggests important routes to success for youths in other high risk settings.
The Discourse-Historical Approach: The Comparison of The Statelessness Identity in Germany and Latvia

The statelessness is not a a new issue within European countries. Statelessness had made some highlights but finally gained significant attention after the collapse of the former Soviet Union, Czechoslovakia and Yugoslavia in the late 1980s. This study aims to see how the European Commission and the European Network on Statelessness talk about identity in the statelessness issue in Germany and Latvia. Through the qualitative research method, specifically employs the Discourse-Historical Approach (DHA) from Ruth Wodak, this study aims to reveal the language and the linguistics used in the ad-hoc query and statelessness index to further investigate the identity perspective of statelessness issue in Germany and Latvia. The main finding is that there are several distincting between Germany and Latvia to handle statelessness issue in their respective countries. While Germany has a problem to conduct statelessness determination procedure, Latvia has succeed to created its own statelessness determination procedure although in the end has created categorisation bias. This finding appears in both Statelessness Index and in the Ad-hoc query.Keywords: statelessness, identity, Germany, Latvia, Discourse-Historical approach
Precautionary Savings, Retirement Planning and Misperceptions of Financial Literacy

We measure financial literacy among LinkedIn members, complementing standard questions with additional questions that allow us to gauge self-perceptions of financial literacy. Average financial literacy is surprisingly low given the demographics of our sample: fewer than two-thirds of CFOs, CEOs, and COOs complete the test correctly. Financial literacy, precautionary savings and retirement planning are positively correlated, but this is mostly driven by perceived, not actual, literacy: controlling for self-perceptions, actual literacy has low predictive power. Perceptions drive decision-making among low-literacy respondents and are associated with mistaken beliefs about financial products and less willingness to accept financial advice.
Revision of the brachiopod Cytina rigauxi Maillieux, 1909 and description of a new ambocoeliid genus (Dionacoelia n. gen.) from the Frasnian of southern Belgium

Cyrtina rigauxi MAILLIEUX, 1909 is transferred to the genus Acutatheca STAINBROOK, 1945 thus mentioned for the first time in the Frasnian of the Dinant Synclinorium and Roly Massif (Neuville Formation, Lower Palmatolepis rhenana Zone). MAILLIEUX (1940, 1941) included Acutatheca rigauxi in Cyrtina demarlei BOUCHARD (nomen nudum) and C. heteroclita (DEFRANCE, 1824). The specimens identified as Martiniopsis (Elivella) rigauxi by MAILLIEUX (1940, 1941) [= Echinocoelia rigauxi sensu VANDERCAMMEN (1956)] do not belong to C. rigauxi MAILLIEUX, 1909. They are redescribed as Dionacoelia secessus n. gen., n. sp. , a species occurring with certainty in the Ermitage Member of the Moulin Lienaux Formation (Palmatolepis punctata Zone).
Angular Momentum Evolution of Galaxies: the Perspective of Hydrodynamical Simulations

Abstract Until a decade ago, galaxy formation simulations were unable to simultaneously reproduce the observed angular momentum (AM) of galaxy disks and bulges. Improvements in the interstellar medium and stellar feedback modelling, together with advances in computational capabilities, have allowed the current generation of cosmological galaxy formation simulations to reproduce the diversity of AM and morphology that is observed in local galaxies. In this review I discuss where we currently stand in this area from the perspective of hydrodynamical simulations, specifically how galaxies gain their AM, and the effect galaxy mergers and gas accretion have on this process. I discuss results which suggest that a revision of the classical theory of disk formation is needed, and by discussing what the current challenges are.
Facial Nonrepetitive Graph Colourings

A facial path is a path of consecutive vertices on the boundary walk of a face of a plane graph G. A nonrepetitive facial colouring of G is a vertex colouring such that the sequence of colours of any facial path is nonrepetitive, and the minimum number of colours required for such a colouring is the facial Thue chromatic number of G. Using a new blocking set technique, we show that the facial Thue chromatic number of an outerplane graph is bounded by 11, and by 7 for outerplane graphs that contain at most one 2-connected component. Furthermore, we show that the facial Thue chromatic number of plane graphs is bounded by twice the facial Thue chromatic number of outerplane graphs, which results in an upper bound of 22 for this parameter, an improvement over the previous bound of 24 by Barat and Czap (Journal of Graph Theory, 2013).

An improved corner detection algorithm used in video statistics

In order to address the difficult problem to determine the number of populations, this paper improves the algorithm based on the Harris point detection algorithm, and the number of people is returned through the first-order linear regression model. First of all, according to the shortcomings of Harris corner algorithm in population statistics, an adaptive gray difference idea is proposed, and the concept of integral image is introduced to overcome its defects in noise immunity and real-time operation. Secondly, in view of the large error generated in the process of population statistics in the first-order static model, a dynamic linear model regression method is proposed. In this method, it is believed that there is certain proportionality coefficient between each frame of corner points and the number of people with the change of time, and this coefficient has certain correlation with the angle points in the previous frame and current frame. At the same time, in order to eliminate the number of redundant corners generated in the corner statistics process, the frame difference method is used to filter the stationary point. Finally, the number of people is returned through first-order linear model.
Free-Breathing R2* Mapping for Hepatic Iron Quantification Using Respiratory Motion-Resolved 3D Multi-Echo UTE Cones MRI

Respiratory motion is one of the major factors hindering accurate R2* mapping for hepatic iron quantification. In this work, motion-resolved 3D multi-echo UTE cones MRI with pseudo-random view ordering was implemented for motion-robust and free-breathing R2* mapping of hepatic iron. Compared to conventional gridding reconstruction, motion-resolved reconstruction reduced the overestimation of R2* induced by respiratory motion artifacts, enabling an accurate measurement of R2*. 3D multi-echo UTE cones MRI with motion-resolved reconstruction demonstrated the feasibility of accurate free-breathing R2* mapping for hepatic iron quantification.
Unsupervised category learning with integral-dimension stimuli

Despite the recent surge in research on unsupervised category learning, the majority of studies have focused on unconstrained tasks in which no instructions are provided about the underlying category structure. Relatively little research has focused on constrained tasks in which the goal is to learn predefined stimulus clusters in the absence of feedback. The few studies that have addressed this issue have focused almost exclusively on stimuli for which it is relatively easy to attend selectively to the component dimensions (i.e., separable dimensions). In the present study, we investigated the ability of participants to learn categories constructed from stimuli for which it is difficult, if not impossible, to attend selectively to the component dimensions (i.e., integral dimensions). The experiments demonstrate that individuals are capable of learning categories constructed from the integral dimensions of brightness and saturation, but this ability is generally limited to category structures requiring selective attention to brightness. As might be expected with integral dimensions, participants were often able to integrate brightness and saturation information in the absence of feedback—an ability not observed in previous studies with separable dimensions. Even so, there was a bias to weight brightness more heavily than saturation in the categorization process, suggesting a weak form of selective attention to brightness. These data present an important challenge for the development of models of unsupervised category learning.
