Query Expansion Using WordNet and Association

Query expansion is the process of adding additional relevant terms to the original queries to improve the performance of information retrieval systems. However, previous studies showed that automatic query expansion using WordNet do not lead to an improvement in the performance. One of the main challenges of query expansion is the selection of appropriate terms. In this paper, the authors review this problem using Arabic WordNet and Association Rules within the context of Arabic Language. The results obtained confirmed that with an appropriate selection method, the authors are able to exploit Arabic WordNet to improve the retrieval performance. Their empirical results on a sub-corpus from the Xinhua collection showed that their automatic selection method has achieved a significant performance improvement in terms of MAP and recall and a better precision with the first top retrieved documents.
Hidden framings and hidden asymmetries in the measurement of personality--A combined lens-model and frame-of-reference perspective.

OBJECTIVE The symmetry principle and the frame-of-reference perspective have each made contributions to improving the measurement of personality. Although each perspective is valuable in its own right, we argue that even greater improvement can be achieved through the combination of both. Therefore, the goal of the current article was to show the value of a combined lens-model and frame-of-reference perspective. METHOD We conducted a literature review to summarize relevant research findings that shed light on the interplay of both perspectives and developed an integrative model. RESULTS Based on the literature review and on theoretical grounds, we argue that a basic premise of the frame-of-reference literature--that personality items are open to interpretation and allow individuals to impose their own contextual framings--should be considered from a symmetry perspective. Unintended context-specificity in items may "spread" to personality facets and domains, and thus, impact the symmetry of personality measures with other criteria. As the individuals´ frames-of-reference and (a)symmetric relationships are not always apparent, we term them as "hidden. " CONCLUSIONS The proposed combination of lens-model and frame-of-reference perspectives provides further insights into current issues in personality research and uncovers important avenues for future research.
A homogenization result for weak membrane energies

We prove a $\Gamma$-convergence result for space dependent weak membrane energies, that is for 'truncated quadratic potentials', that are quadratic below some threshold (depending on the pair of points that we are considering) and constant above. We prove that the limit surface energy density coincides with the one for spin systems, while the bulk energy density is not affected by the different levels of truncation and coincides with an purely elastic energy density.
Multi-objective optimization of high speed vehicle-passenger catamaran by genetic algorithm: Part II Computational simulations

Multi-objective optimization of high speed vehicle-passenger catamaran by genetic algorithm: Part II Computational simulations Real ship structural design problems are usually characterized by presence of many conflicting objectives. Simultaneously, a complete definition of the optimum structural design requires a formulation of size-topology-shape-material optimization task unifying the optimization problems of the four areas and giving an effective solution of the problem. So far, a significant progress towards the solution of the problem has not been obtained. An objective of the present paper was to develop an evolutionary algorithm for multi-objective optimization of structural elements of large spatial sections of ships. Selected elements of the multi-criteria optimization theory have been presented in detail. Methods for solution of the multi-criteria optimization problems have been discussed with the focus on the evolutionary optimization algorithms. In the paper an evolutionary algorithm where selection takes place based on the aggregated objective function combined with domination attributes as well as distance to the asymptotic solution, is proposed and applied to solve the problem of optimizing structural elements with respect to their weight and surface area on a high speed vehicle-passenger catamaran structure, with several design variables, such as plate thickness, scantlings of longitudinal stiffeners and transverse frames, and spacing between longitudinal and transversal members, taken into account. Details of the computational models were at the level typical for conceptual design. Scantlings were analyzed by using selected rules of a classification society. The results of numerical experiments with the use of the developed algorithm, are presented. They show that the proposed genetic algorithm can be an efficient tool for multi-objective optimization of ship structures. The paper is published in three parts: Part I: Theoretical background on evolutionary multi-objective optimization, Part II: Computational investigations, and Part III: Analysis of the results.
A chiral organocatalytic polymer-based monolithic reactor

Radical copolymerisation of divinylbenzene and a properly modified enantiomerically pure imidazolidinone inside a stainless steel column in the presence of dodecanol and toluene as porogens afforded the first example of a chiral organocatalyst immobilized onto a monolithic reactor. Organocatalyzed cycloadditions between cyclopentadiene and cinnamic aldehyde were performed under continuous-flow conditions; by optimizing the experimental set up, excellent enantioselectivities (90% ee at 25 °C) and high productivities (higher than 330) were obtained, thus showing that a catalytic reactor may work efficiently to continuously produce enantiomerically enriched compounds. The same catalytic reactor was also employed to carry out three different stereoselective transformations in continuo, sequentially, inside the chiral column (Diels–Alder, 1,3-dipolar nitrone-olefin cycloaddition, and Friedel–Crafts alkylation); excellent results were obtained in the case of the former two reactions (up to 99% yield, 93% ee and 71% yield, 90% ee, at 25 °C, respectively). In addition to simplify the product recovery, the monolithic reactor performed better than the same supported organocatalyst in a stirred flask and could be kept working continuously for more than 8 days.
Avalanche : The Power of Metastable Consensus Team Rocket

This paper introduces a new family of leaderless Byzantine fault tolerance protocols, built around a metastable mechanism. These protocols provide a strong probabilistic safety guarantee in the presence of Byzantine adversaries, while their concurrent nature enables them to achieve high throughput and scalability. Unlike blockchains that rely on proofof-work, they are quiescent and green. Unlike traditional consensus protocols having leader nodes that process O(n) information (in terms of number of bits exchanged), no node processes more than O(k) for some security parameter k. The paper describes the protocol family, instantiates it in three separate protocols, analyzes their guarantees, and describes how they can be used to construct the core of an internet-scale electronic payment system. The system is evaluated in a large scale deployment. Experiments demonstrate that the system can achieve high throughput (3400 tps), provide low confirmation latency (1.35 sec), and scale well compared to existing systems that deliver similar functionality. For our implementation and setup, the bottleneck of the system is in transaction verification.
1 ICC / P 602 Recent Magneto-Inertial Fusion Experiments on FRCHX

Magneto-Inertial Fusion (MIF) approaches take advantage of embedded magnetic field to improve plasma energy confinement by reducing thermal conduction relative to conventional inertial confinement fusion (ICF). MIF reduces required precision in the implosion and the convergence ratio. Since 2008 [1], AFRL and LANL have developed one version of MIF. We have (1) reliably formed, translated, and captured Field Reversed Configurations (FRCs) in magnetic mirrors inside metal shells or liners in preparation for subsequent compression by liner implosion; (2) imploded a liner with interior magnetic mirror field, obtaining evidence for compression 1.36 T field to 540 T; (3) performed a full system experiment of FRC formation, translation, capture, and imploding liner compression operation; (4) identified by comparison of 2D-MHD simulation and experiments factors limiting the closedfield lifetime of FRCs to about half that required for good liner compression of FRCs to multi-keV, 10 ion/cm, high energy density plasma (HEDP) conditions; and (5) designed and prepared hardware to increase that closed field FRC lifetime to the required amount. Those lifetime experiments are now underway, with the goal of at least doubling closed-field FRC lifetimes and performing FRC implosions to HEDP conditions this year. These experiments have obtained imaging evidence of FRC rotation, and of initial rotation control measures slowing and stopping such rotation.
Health Behavior Among Men Occupying Multiple Family Roles and the Moderating Effects of Perceived Partner Relationship Quality

Men in the U.S. are increasingly involved in their children’s lives and currently represent 40% of informal caregivers to dependent relatives or friends aged 18 years or older. Yet, much more is known about the health effects of varying family role occupancies for women relative to men. The present research sought to fill this empirical gap by first comparing the health behavior (sleep duration, cigarette smoking, alcohol consumption, exercise, fast food consumption) of men who only occupy partner roles and partnered men who also fill father, informal caregiver, or both father and informal caregiver (i
MIMO ANTENNA MUTUAL COUPLING REDUCTION FOR WLAN USING SPIRO MEANDER LINE UC-EBG

This paper presents designs of novel E-plane spiro meander line uniplanar compact electromagnetic bandgap (E-SMLUC-EBG) and H-plane spiro meander line uniplanar compact electromagnetic bandgap (H-SMLUC-EBG) structures. The proposed EBG has been applied in mutual coupling reduction of a dual-element multiple input multiple output (MIMO) antenna system for WLAN by placing an EBG structure between the radiating antennas. Compact size of EBG helps in reducing the edge to edge distance between antennas which is 0. 14λ0 in this case, and it increases the compactness of integrated circuit. It gives 19 dB and 11 dB simulated mutual coupling reduction in E-plane and Hplane respectively at 5.8 GHz. Measured isolation improvement of 20.3 dB for E-plane and 14.7 dB for H-plane has been achieved. This coupling reduction is also confirmed by surface current and correlation coefficient plots. The four-element (2×2) MIMO antenna system with proposed EBG is also simulated.

Reproducibility of two-dimensional electrophoresis gel images of pea (Pisum sativum L.) seed proteins evaluated using scatter plots - a short report.

The aim of this study was to evaluate plots showing a linear correlation between the parameters characterising protein content in the spots obtained using two-dimensional electrophoresis (scatter plots). The correlation coefficient of normalized spot volume may be used to determine regions with increased reproducibility. In our experiment, conducted using pea seed proteins, the correlation coefficient reached 0.980 in such regions, compared with 0.917 noted for the entire gel surface. The correlation coefficient calculated based on scatter plots may serve as a tool for the preliminary selection of regions characteristic of a given proteome.
State of the Art on : Graph Representation Learning

In real life, problems may present complex underlying structures that need to be captured somehow. To deal with this issue a possible solution is to use a universal language that allows for an efficient representation, and that can be further extended to multiple fields, such as computer science, social science, economics, physics and biology. Despite having different goals, all the aforementioned disciplines deal with complex systems that can be represented by means of graphs. In fact, many real-life problems can be modelled using a graph data structure, e.g. Social network [18, 25], Regulatory networks, Recommender systems [6], Drug design [23, 19] and Brain functional networks [4]. From a modelling perspective the system is quite simple, we have objects interacting with each other, and therefore only two elements need to be defined, i.e. nodes and links. For example, in case of a social networks people can be represented by means of nodes while friendship relation through edges. Once the model of the system has been realized, the goal is to extract useful information from it, that can be later exploited to perform a specific task.
Kinematics and Dynamics Analysis of a 3-DOF Upper-Limb Exoskeleton with an Internally Rotated Elbow Joint

The contradiction between self-weight and load capacity of a power-assisted upper-limb exoskeleton for material hanging is unresolved. In this paper, a non-anthropomorphic 3-degree of freedom (DOF) upper-limb exoskeleton with an internally rotated elbow joint is proposed based on an anthropomorphic 5-DOF upper-limb exoskeleton for power-assisted activity. The proposed 3-DOF upper-limb exoskeleton contains a 2-DOF shoulder joint and a 1-DOF internally rotated elbow joint. The structural parameters of the 3-DOF upper-limb exoskeleton were determined, and the differences and singularities of the two exoskeletons were analyzed. The workspace, the joint torques and the power consumption of two exoskeletons were analyzed by kinematics and dynamics, and an exoskeleton prototype experiment was performed. The results showed that, compared with a typical anthropomorphic upper-limb exoskeleton, the non-anthropomorphic 3-DOF upper-limb exoskeleton had the same actual workspace; eliminated singularities within the workspace; improved the elbow joint force situation; and the maximum elbow joint torque, elbow external-flexion/internal-extension and shoulder flexion/extension power consumption were significantly reduced. The proposed non-anthropomorphic 3-DOF upper-limb exoskeleton can be applied to a power-assisted upper-limb exoskeleton in industrial settings.

Rangeland degradation and restoration: A global perspective

Rangelands are lands on which the indigenous vegetation is predominantly grasses, grass-like plants, forbs, or shrubs and are managed as a natural ecosystem. They include grasslands, savannas, shrublands, deserts, tundras, marshes, and meadows. Globally, rangelands comprise the largest land use, estimated to cover about 25 % of Earth’s land surface. This makes them an essential resource for both maintaining environmental services like biodiversity conservation and as a source of livelihood, especially for rural communities. Rangelands are used primarily as a source of feed for livestock. They, however, provide other secondary resources such as firewood, wild foods, medicinal plants, and water. Land degradation is the major challenge in the rangelands of the earth. Rangeland degradation is occurring as a result of no grazing management plans, removal of vegetation for fuel wood and no clear authority of rangeland ownership. The major indicators of rangelands degradation are shift in species composition, loss of range biodiversity, reduction in biomass production, less plant cover, low small ruminant productivity, and soil erosion. Major changes in rangeland surface morphology and soil characteristics have a drastic effect on the primary productivity of the rangeland ecosystem, and in turn on livestock production. The condition of the grazing area is influenced principally by herbivore species, densities and landscape structure. Population densities of grazing animals and intensity of their foraging can determine some rangeland dynamics. It determines whether herbivore increases nutrient cycling and plant productivity or affects plant communities by driving changes in successional pathways decreasing nutrient cycling, and influencing biodiversity of those communities. Management of rangeland degradation can be divided into preventative and restoration measures. Answers to preventative measures can often be found within the causes of land degradation. In view of the massive scale of land degradation, restoration is of significant importance to land owners.
The Effects of Exposure of Political Affiliation and Race on Perceptions of White Privilege and Anti-black Discrimination

This thesis explored the effects of exposure to different political affiliations and races on participants’ perceptions of white privilege and anti-black discrimination. Recent research has studied the effects of race, framing, and guilt on the acknowledgement of white privilege, but none have explored how political affiliation can affect these perceptions. If simple exposure to these symbols of political affiliation can alter the perceptions of those exposed, perhaps the results of this study could be used to bring about awareness and ease political tensions. Participants were placed in one of six groups consisting of either a white or black experimenter wearing a Black Lives Matter shirt, Make America Great Again shirt, or a plain black shirt. Participants completed a series of three surveys: a demographic survey, a belief in White Privilege Scale, and the Other Focused Belief in Discrimination Scale. A two-way ANOVA was used to analyze the data. There were no significant differences in scores on the White Privilege Scale based on race or shirt of the experimenter.
Nitrogen deposition impacts on the amount and stability of soil organic matter in an alpine meadow ecosystem depend on the form and rate of applied nitrogen

The effects of atmospheric nitrogen (N) deposition on carbon (C) sequestration in terrestrial ecosystems are controversial. Therefore, it is important to evaluate accurately the effects of applied N levels and forms on the amount and stability of soil organic carbon (SOC) in terrestrial ecosystems. In this study, a multi‐form, small‐input N addition experiment was conducted at the Haibei Alpine Meadow Ecosystem Research Station from 2007 to 2011. Three N fertilizers, NH4Cl, (NH4)2SO4 and KNO3, were applied at four rates: 0, 10, 20 and 40 kg N ha−1 year−1. One hundred and eight soil samples were collected at 10‐cm intervals to a depth of 30 cm in 2011. Contents and δ13C values of bulk SOC were measured, as well as three particle‐size fractions: macroparticulate organic C (MacroPOC, > 250 µm), microparticulate organic C (MicroPOC, 53–250 µm) and mineral‐associated organic C (MAOC, < 53 µm). The results show that 5 years of N addition changed SOC contents, δ13C values of the bulk soils and various particle‐size fractions in the surface 10‐cm layer, and that they were dependent on the amounts and forms of N application. Ammonium‐N addition had more significant effects on SOC content than nitrate‐N addition. For the entire soil profile, small additions of N increased SOC stock by 4.5% (0.43 kg C m−2), while medium and large inputs of N decreased SOC stock by 5.4% (0.52 kg C m−2) and 8.8% (0.85 kg C m−2), respectively. The critical load of N deposition appears to be about 20 kg N ha−1 year−1. The newly formed C in the small‐input N treatment remained mostly in the > 250 µm soil MacroPOC, and the C lost in the medium or large N treatments was from the > 53 µm POC fraction. Five years of ammonium‐N addition increased significantly the surface soil POC:MAOC ratio and increased the instability of soil organic matter (SOM). These results suggest that exogenous N input within the critical load level will benefit C sequestration in the alpine meadow soils on the Qinghai–Tibetan Plateau over the short term.
How do academia and society react to erroneous or deceitful claims? The case of retracted articles’ recognition

Researchers give credit to peer-reviewed, and thus, credible publications through citations. Despite a rigorous reviewing process, certain articles undergo retraction due to disclosure of their ethical or scientific deficiencies. It is, therefore, important to understand how society and academia react to the erroneous or deceitful claims and purge the science of their unreliable results. Applying a matched-pairs research design, this study examined a sample of medicine-related retracted and non-retracted articles matched by their content similarity. The regression analysis revealed similarities in obsolescence trends of the retracted and non-retracted groups. The Generalized Estimating Equations showed that citations are affected by the retraction status, life after retraction, life cycle and the journals’ previous reputation, with the two formers being the strongest in positively predicting the citations. The retracted papers obtain fewer citations either before or after retraction, implying academia’s watchful reaction to the low-quality papers even before official announcement of their fallibility. They exhibit an equal or higher social recognition level regarding Tweets and Blog Mentions, while a lower status regarding Mendeley Readership. This could signify social users’ sensibility regarding scientific quality since they probably publicise the retraction and warn against the retracted items in their tweets or blogs, while avoiding recording them in their Mendeley profiles. Further scrutiny is required to gain insight into the sensibility, if any, about scientific quality. The study’s originality relies on matching the retracted and non-retracted papers with their topics and neutralising variations in their citation potentials. It is also the first study comparing the groups’ social impacts.
