Solar twins in the ELODIE archive

A large dataset of ~2800 spectra extracted from the ELODIE archive was analysed in order to find solar twins. A list of stellar spectra closely resembling the spectrum of the Sun was selected by applying a purely differential method, directly on the fluxes. As solar reference, 18 spectra of asteroids, Moon and blue sky were used. Atmospheric parameters and differential abundances of 8 chemical elements were determined for the solar twin candidates, after a careful selection of appropriate lines. The Li feature of the targets was investigated and additional information on absolute magnitude and age was gathered from the literature. HIP076114 (HD138573) is our best twin candidate, looking exactly like the Sun in all these properties.
Investigating the influence of the most commonly used external variables of TAM on students' Perceived Ease of Use (PEOU) and Perceived Usefulness (PU) of e portfolios
Venue: Comput. Hum. Behav.

Engagement with e portfolios has been shown to improve students' learning. However, what influences students to accept e portfolios is a question that needs careful study. The purpose of this study is to investigate the influence of Self Efficacy, Subjective Norm, Enjoyment, Computer Anxiety and Experience on students' Perceived Ease of Use (PEOU) and Perceived Usefulness (PU) of an e portfolio system and their Behavioural Intention (BI) to use the system for learning. To do this, the study tested and used the General Extended Technology Acceptance Model for E Learning (GETAMEL) in the context of e portfolios. Valid data were collected from 242 UK undergraduate students who had been introduced to e portfolios. The data set was analysed using SPSS software. Results showed that the best predictor of student's Perceived Ease of Use of the e portfolio is Experience, followed by Enjoyment, Self Efficacy and Subjective Norm. The best predictor of student's Perceived Usefulness of the e portfolio is Perceived Ease of Use followed by Enjoyment. Both Perceived Ease of Use and Perceived Usefulness predict student's Behavioural Intention to Use the e portfolio. The findings improve understanding regarding acceptance of e portfolio systems and this work is therefore of particular interest to researchers, developers and practitioners of e portfolios. We validated and used the GETAMEL to examine students' e portfolio adoption.Four variables affected Perceived Ease of Use (PEOU) of the e portfolio.The four variables are Experience, Enjoyment, Self Efficacy and Subjective Norm.PEOU and Enjoyment affected Perceived Usefulness (PU) of the e portfolio.Both PEOU and PU affected students' intention to use the e portfolio.
What keeps the mobile hotel booking users loyal? Investigating the roles of self efficacy, compatibility, perceived ease of use, and perceived convenience
Venue: Int. J. Inf. Manag.

Convenience, compatibility, and PEOU are positively associated with MHB loyalty.Compatibility significantly influences PEOU and perceived convenience.PEOU has a significant impact on perceived convenience. With the advancements in mobile technologies, mobile hotel booking (MHB) has become an important distribution channel for hotels and online travel agencies (OTAs) Understanding MHB users loyalty intentions toward this technology has become equally important for MHB service providers, as it is essential for them to retain their customers. However, existing literature in the context of mobile booking has mainly focused on the adoption and acceptance of this technology. The purpose of this paper is to empirically test a research model that incorporates antecedents of mobile shopping loyalty in a hotel booking context. The proposed model was tested through structural equation modeling (SEM) by using empirical data collected from 396 MHB users. Study results revealed that convenience, compatibility, and perceived ease of use (PEOU) had a significant impact on the users loyalty intentions toward MHB technology. In addition, compatibility significantly influenced PEOU and convenience and PEOU had a significant impact on loyalty and convenience. Study results provide valuable theoretical and practical implications for various players in the hotel and travel industry including hoteliers, OTAs, mobile app developers and hospitality technology vendors.
The Effects of Perceived Usefulness and Perceived Ease of Use on Continuance Intention to Use E Government

E government can offer improved quality of information supply and fewer administrative burdens. Despite significant benefits in e government systems, the extent to which citizens have been able to assimilate these systems is still unclear. This study analyzed the relationships between predictor's variable (perceived usefulness and perceived ease of use) and criterion variable which is continuance intention to use e government. A total of 543 government servant who taught in Malaysian public schools completed the questionnaire and became the participants of this study. To answer the research questions, multiple regression analysis was applied. The results indicate that perceived usefulness (b 0.65, p
Carbon price and wind power support in Denmark

This paper aims at characterizing the conditions of wind power deployment in order to infer a carbon price level that would provide wind power with comparable advantage over fossil fuel technologies as effective wind support policies. The analysis is conducted on Danish data from 2000 to 2010, i.e. after market liberalization took place in 2000. Probit technique is used to analyze the connection of new turbines to the grid each month and tobit analysis is employed on the additional capacity installed monthly. I find that the level and type of the support policy are the dominant drivers of deployment. Electricity price impact is not visible. The investment cost impact is not significant either, but the effect of the interest rate, although not visible in the probit analysis, is significant in the tobit analysis. The number of turbines already installed, that is taken as a proxy for the sites availability, does not have any significant effect either. A feed in tariff significantly brings more wind power in than a premium policy. The fact that the support policy is a feed in tariff rather than a premium increases the additional capacity installed monthly by up to several tens MW. The additional capacity installed monthly increases by up to thousand kW for each additional e/MWh of support. If the policy is a premium, I find that 24 e/MWh of support in addition to electricity price is needed to observe the connection of new turbines to the grid with a 0.5 probability. I convert this support level into a carbon price of 28 e/ton if wind power competes with coal, and 50 e/t if it competes with gas.
Popular Theatre for Science Engagement: Audience Engagement with Human Cloning Following a Production of Caryl Churchill's A Number

Research into the role of fiction in engaging people with science is a growing area, but a little studied medium in this respect is 'popular theatre' or non pedagogic theatre that exists primarily as a work of art. This study investigated audience engagement with human cloning issues after seeing a performance of Caryl Churchill's 2002 cloning themed play, A Number, and compared this to the level and quality of engagement shown by people who participated in a group discussion about human cloning. The play prompted a majority of audience members to be engaged with human cloning, markedly increased the salience of the issue for its audience, and brought to light new perspectives on it for them. The proportion of people who reported thinking about human cloning two months after the play was quantitatively similar to those who took part in a group discussion, but the conversations that resulted from each stimulus were qualitatively different, with the play providing a concrete case study that grounded discussion. The unique contributions that popular theatre can offer science communication are discussed.
Quantifying market risk with Value at Risk or Expected Shortfall? Consequences for capital requirements and model risk

The Basel Committee on Banking Supervision recently proposed fundamental changes in the regulatory treatment of financial institutions' trading book positions. Among others, a replacement of Value at Risk (a=0.99) by Expected Shortfall (a=0.975) for the quantification of market risk is recommended. While this increases capital requirements for heavy tailed risks, its consequences for model risk related to the estimation process have not been explored. Hence, the aim of this paper is to analyze how both risk measures react to different sources of model risk in order to better understand the impact of the intended change in risk measures. Our results show that the Expected Shortfall (a=0.975) is more sensitive towards regulatory arbitrage and parameter misspecification. We find that this is based on a trade off between a model's ability to better capture the heavy tailed behavior of risks and a higher vulnerability to model risk. These new aspects should be taken into account in the regulatory decision for Expected Shortfall (a=0.975)
Why Does Idiosyncratic Risk Increase with Market Risk?

From 1963 through 2015, idiosyncratic risk (IR) is high when market risk (MR) is high. We show that the positive relation between IR and MR is highly stable through time and is robust across exchanges, firm size, liquidity, and market to book groupings. Though stock liquidity affects the strength of the relation, the relation is strong for the most liquid stocks. The relation has roots in fundamentals as higher market risk predicts greater idiosyncratic earnings volatility and as firm characteristics related to the ability of firms to adjust to higher uncertainty help explain the strength of the relation. Consistent with the view that growth options provide a hedge against macroeconomic uncertainty, we find evidence that the relation is weaker for firms with more growth options.

Venue: HCI

This paper aims to provide the theoretical framework and methodology for the definition of data collection tools designed to assess the effectiveness and impact of training envisaged by the LEARNING4WORK project. This project is based on the development of learning strategies within the framework of Vocation Training, in order to improve learning processes and make them more applicable in the real working world while minimizing the number of student drop outs. Learning methods are re conceptualized through the use of immersive worlds and role and project orientated learning. Scenario Centered Curriculum (SCC) was applied to promote the acquisition and development of international cooperation skills through the use of Information Communication Technologies (ICT) tools and systems. The paper focuses on the design process of the evaluation initial questionnaires (or Pre test) starting from the theoretical framework established in the field of learning in formal, informal and non formal educational contexts, applied to an innovative vision of education and training, centered on the learner's future professional role.
Limited erosion of genetic and species diversity from small forest patches: sacred forest groves in an Afrotropical biodiversity hotspot have high conservation value for butterflies.

Sacred forest groves are often located in some of the world's hottest hotspots of biodiversity, and consequently have high potential conservation value. Recent efforts to quantify their value have focused nearly exclusively on a single component of diversity, species diversity within communities, which may or may not be an effective proxy for a second fundamental component of diversity, genetic diversity within populations. We studied fruit feeding butterfly communities to simultaneously assess to what extent five small sacred groves have retained the level of species and genetic diversity found in two much larger forest reserves. We additionally evaluate whether measures correlate across habitat fragments to investigate how closely these two components of diversity mirror each other. We quantified the diversity and composition of the fruit feeding butterfly communities at each site and also the haplotype diversity within three specific species that differ with respect to their sensitivity to habitat fragmentation. Of the multiple measures of species and genetic diversity computed, only rarefied species richness was correlated with forest fragment size and even in this case the relationship was weak. Importantly, the limited decline in species richness documented in the sacred groves was not due to species replacements, whereby common, broadly distributed, generalists supplanted more vulnerable species in these communities. Although similar processes are known to drive declines in both species and gene diversity, we found only limited evidence of positive species genetic diversity correlations (SGDCs) and only in the species most sensitive to fragmentation. Thus, a conservation strategy that emphasizes species complementarity or richness may be ineffective at capturing other critical levels of biodiversity. Overall, our findings demonstrate that even very small forest patches can have a conservation value that rivals that of much larger forest reserves. The implementation of official national and international initiatives that preserve and strengthen existing community based conservation practices is critically needed to ensure that indigenous conservation areas persist into the future.
Impact of Dental Implant Surface Modifications on Osseointegration
Venue: BioMed research international

The aim of this paper is to review different surface modifications of dental implants and their effect on osseointegration. Common marketed as well as experimental surface modifications are discussed.  The major challenge for contemporary dental implantologists is to provide oral rehabilitation to patients with healthy bone conditions asking for rapid loading protocols or to patients with quantitatively or qualitatively compromised bone. These charging conditions require advances in implant surface design. The elucidation of bone healing physiology has driven investigators to engineer implant surfaces that closely mimic natural bone characteristics. This paper provides a comprehensive overview of surface modifications that beneficially alter the topography, hydrophilicity, and outer coating of dental implants in order to enhance osseointegration in healthy as well as in compromised bone. In the first part, this paper discusses dental implants that have been successfully used for a number of years focusing on sandblasting, acid etching, and hydrophilic surface textures. Hereafter, new techniques like Discrete Crystalline Deposition, laser ablation, and surface coatings with proteins, drugs, or growth factors are presented.  Major advancements have been made in developing novel surfaces of dental implants. These innovations set the stage for rehabilitating patients with high success and predictable survival rates even in challenging conditions.
Precision of Dental Implant Digitization Using Intraoral Scanners.
Venue: The International journal of prosthodontics

The digitization of scanbodies on dental implants is required to use computer aided design/computer assisted manufacture processes for implant prosthetics. Little is known about the accuracy of scanbody digitization with intraoral scanners and dental lab scanners. This study aimed to examine the precision of different intraoral digital impression systems as well as a dental lab scanner using commercially available implant scanbodies.  Two study models with a different number and distribution of dental implant scanbodies were produced from conventional implant impressions. The study models were scanned using three different intraoral scanners (iTero, Cadent; Trios, 3Shape; and True Definition, 3M ESPE) and a dental lab scanner (D250, 3Shape) For each study model, 10 scans were performed per scanner to produce repeated measurements for the calculation of precision. The distance and angulation between the respective scanbodies were measured. The results of each scanning system were compared using analysis of variance, and post hoc Tukey test was conducted for a pairwise comparison of scanning devices.  The precision values of the scanbodies varied according to the distance between the scanbodies and the scanning device. A distance of a single tooth space and a jaw traversing distance between scanbodies produced significantly different results for distance and angle measurements between the scanning systems (P .05)  The precision of intraoral scanners and the dental lab scanner was significantly different. The precision of intraoral scanners decreased with an increasing distance between the scanbodies, whereas the precision of the dental lab scanner was independent of the distance between the scanbodies.
Surface Structural Transition Induced by Gradient Polyanion Doping in Li Rich Layered Oxides: Implications for Enhanced Electrochemical Performance

Lithium rich layered oxides (LLOs) exhibit great potential as high capacity cathode materials for lithium ion batteries, but usually suffer from capacity/voltage fade during electrochemical cycling. Herein, a gradient polyanion doping strategy is developed to initiate surface structural transition to form a spinel like surface nanolayer and a polyanion doped layered core material in LLOs simultaneously. This strategy integrates the advantages of both bulk doping and surface modification as the oxygen close packed structure of LLOs is stabilized by polyanion doping, and the LLO cathodes are protected from steady corrosion induced by electrolytes. A LLO material modified with 5 at% phosphate (5%P@LLO) shows a high reversible discharge capacity of 300 mAh g 1 at 0.1 C, excellent cycling stability with a capacity retention of 95% after 100 cycles, and enhanced electrode kinetics. This gradient doping strategy can be further extended to other polyanion doped LLO materials, such as borate and silicate polyanions.
Logic Design Within Memristive Memories Using Memristor Aided loGIC (MAGIC)
Venue: IEEE Transactions on Nanotechnology

Realizing logic operations within passive crossbar memory arrays is a promising approach to enable novel computer architectures, different from conventional von Neumann architecture. Attractive candidates to enable such architectures are memristors, nonvolatile memory elements commonly used within a crossbar, that can also perform logic operations. In such novel architectures, data are stored and processed within the same entity, which we term as memristive memory processing unit (MPU) In this paper, Memristor Aided loGIC (MAGIC) family is discussed with various design considerations and novel techniques to execute logic within an MPU. We present a novel resistive memory the transpose memory, which adds additional functionality to the memristive memory, and compare it with a conventional memristive memory. A case study of an adder is presented to demonstrate the design issues discussed in this paper. We compare the proposed design techniques with the memristive IMPLY logic in terms of speed, area, and energy. Our evaluation shows that the proposed MAGIC design is 2.4 x faster and consumes 66.3% less energy as compared with the IMPLY based computing for N bit addition within memristive crossbar memory. Additionally, we compare the proposed design with IMPLY logic family on ISCAS 85 benchmarks, which shows significant improvements in speed (2x) and energy (10x) with similar area.
Maternal Early Pregnancy Serum Metabolomics Profile and Abnormal Vaginal Bleeding as Predictors of Placental Abruption: A Prospective Study
Venue: PloS one

Placental abruption, an ischemic placental disorder, complicates about 1 in 100 pregnancies, and is an important cause of maternal and perinatal morbidity and mortality worldwide. Metabolomics holds promise for improving the phenotyping, prediction and understanding of pathophysiologic mechanisms of complex clinical disorders including abruption. We sought to evaluate maternal early pregnancy pre diagnostic serum metabolic profiles and abnormal vaginal bleeding as predictors of abruption later in pregnancy.  Maternal serum was collected in early pregnancy (mean 16 weeks, range 15 to 22 weeks) from 51 abruption cases and 51 controls. Quantitative targeted metabolic profiles of serum were acquired using electrospray ionization liquid chromatography mass spectrometry (ESI LC MS/MS) and the Absolute IDQ(r) p180 kit. Maternal sociodemographic characteristics and reproductive history were abstracted from medical records. Stepwise logistic regression models were developed to evaluate the extent to which metabolites aid in the prediction of abruption. We evaluated the predictive performance of the set of selected metabolites using a receiver operating characteristics (ROC) curve analysis and area under the curve (AUC) Results Early pregnancy vaginal bleeding, dodecanoylcarnitine/dodecenoylcarnitine (C12 C12:1) and phosphatidylcholine acyl alkyl C 38:1 (PC ae C38:1) strongly predict abruption risk. The AUC for these metabolites alone was 0.68, for early pregnancy vaginal bleeding alone was 0.65, and combined the AUC improved to 0.75 with the addition of quantitative metabolite data (P 0.003) Conclusion Metabolomic profiles of early pregnancy maternal serum samples in addition to the clinical symptom, vaginal bleeding, may serve as important markers for the prediction of abruption. Larger studies are necessary to corroborate and validate these findings in other cohorts.
