When Outcome Expectations Become Habitual: Explaining vs. Predicting New Media Technology Use From a Social Cognitive Perspective

This study examined the triadic relationship between expected outcomes, habit strength, and media technology use within the model of media attendance (Larose & Eastin, 2004). Mobile phone users (N = 664) were divided into two groups using a stratified random sampling method. Respondents of group one (n = 334) were surveyed on existing mobile phone use, respondents of group two (n = 310) were surveyed on the intention to use mobile video phone. On the basis of structural equation analysis, the results of this study support the assumption that within the model of media attendance existing media use is more likely to be explained by habit strength, and new media use is more likely to be predicted by outcome expectations.
The Role of Enterprise Resources Planning (ERP) in the Contribution and Integration of the Information in the Supply Chain

With the increase in the volume of information in the modern organisations and the complexity of the form of today’s business world, the organisations’ environment has been transformed into a dynamic environment. The organisations should adapt themselves with these dynamic changes for two reasons: first, in order to survive, and secondly, to be able to develop in these dynamic and changing environments. They should adopt flexible and innovative systems so that they could both make profits, and at the same time, promote their response in dealing with customers’ needs. In this regards, in the recent years, the Enterprise Resources Planning (ERP) have been adapted as a major step in creating efficient information systems in order to integrate the information and knowledge in an organisation. At the moment, The Enterprise Resources Planning, and Supply Chain Management (SCM) are rapidly growing in the various industries. There is however, a growing need for the incorporation of the applied planning in the business which seems to be an inevitable part of this sector. Adapting the Enterprise Resources Planning will help any organizations to integrate and computerise the duties like, financial affairs, project management, monitoring the inventory of the materials, logistics and so on. From the point of view of meta-organizational systems, this technology helps to establish a chain of suppliers/producers, and customers; the management chain can coordinate and facilitate the relations between the suppliers and customers through the information sharing program along this chain through which the efficiency and effectiveness of the organization could be increased considerably. In this article, we have identified two concepts; one, the Enterprise Resources Planning (ERP), and second, the Supply Chain Management (SCM) from the point of view of their positions in an organization, and their components. The relation between these two concepts and the process of the development of each of them shall be studied then we shall discuss the reasons and necessity of such integration and the information sharing in the supply chain. The role of the Enterprise Resources Planning
Guiding Librarians: Rethinking Library Guides as a Staff Development Tool

Abstract Library subject guides assist students and researchers with accessing and understanding the key resources for their subject or topic areas. From the perspective of academic institutions, subject guides showcase the key subscribed (and open access) resources available to support teaching, learning and research. They are common across university libraries but there is limited research on the benefits library guides may provide librarians themselves, especially in gaining resource knowledge during the creation and maintenance of these guides. This paper proposes the idea that library guides can also function as a staff development tool for the librarians who create and maintain them, based on the results of two surveys undertaken in late 2016 and early 2017. Results reveal the majority of respondents believe that creating library guides have improved their own knowledge of subject resources. Based on our findings, we believe that further research is required on the various techniques librarians use to gain resource knowledge, and the role that subject guides have in this process.
Predicting the popularity of online news from content metadata

Popularity prediction of online news aims to predict the future popularity of news article prior to its publication estimating the number of shares, likes, and comments. Yet, popularity prediction is a challenging task due to various issues including difficulty to measure the quality of content and relevance of content to users; prediction difficulty of complex online interactions and information cascades; inaccessibility of context outside the web; local and geographic conditions; social network properties. This paper focuses on popularity prediction of online news by predicting whether users share an article or not, and how many users share the news adopting before publication approach. This paper proposes the gradient boosting machine for popularity prediction using features that are known before publication of articles. The proposed model shows around 1.8% improvement over previously applied techniques on a benchmark dataset. This model also indicates that features extracted from articles keywords, publication day, and the data channel are highly influential for popularity prediction.
Functional complementation in Saccharomyces cerevisiae under control of the natural yeast promoter

A novel approach for functional complementation of foreign genes in Saccharomyces cerevisiae is presented. This approach is based on the use of the widely available cognate gene plasmids ( e.g. pRS416) of the European Functional Analysis Network (EUROFAN). The functional complementation of the human homolog of YOR159c ( SME1 gene) shown here is the first demonstration of complementation using the original yeast promoter, theoretically offering a more natural regulation of protein expression.
Visualising and interacting with multiple simulations using the multichronic tree

It has been proven experimentally that visual interactive simulation (VIS) is useful in specific contexts. Interaction with the simulated system remains one of the key issues that need to be addressed for VIS to be applied on a large-scale. Little work has been reported recently on using modern computers that offer new types of user interfaces for solving the problem of interactivity with simulations. This paper introduces the multichronic tree user interface concept that provides users with tools for interacting with and visualising multiple simultaneously running simulations. This new VIS concept builds on previous systems, formalises operations and adds several interactive features that can be supported by state-of-the-art computer architectures and display environments. A prototype of the multichronic tree concept is presented along with a discussion on how it could be integrated with other tools in a more general framework for helping users in their simulation exploration process.
Covalently Attached GRGD on Polymer Surfaces Promotes Biospecific Adhesion of Mammalian Cells a

The ability of a surface to support cell adhesion is central to the biocompatibility of that material in several applications, including mammalian cell culture. Adhesion, spreading, and contraction on solid substrates are prerequisites for growth of normal anchorage-dependent cells in vitro. '. 2 A basic understanding of the molecular mechanisms underlying these processes has developed within the past two decades. Fibronectin (FN) was the first cell adhesion molecule (CAM) that was shown to be involved in the adhesion of some avian and mammalian cell types to extracellular substrate^. ^. ^ In the in vitro environment, F N is available from the serum in a form known as cold-insoluble globulin (CIg). For normal attachment and spreading to occur, CIg must be adsorbed to the culture More recently, it has been shown that F N consists of several protease-resistant domains, each of which contains specific binding sites for other extracellular molecules and for the cell surface. ' The cell attachment activity has been localized to a tripeptide sequence, Arg-Gly-Asp (RGD), located in the cell binding domain of FN as well as in several other CAMS. ^ Substrate-bound RGD containing peptide, obtained by direct adsorption to the substrate or by cross-linking of peptide to adsorbed albumin or IgG, promotes fibroblast attachment and spreading. Furthermore, this activity is competitively inhibited by soluble RGD-containing peptides added to the medium.8 Affinity chromatography of cellular extracts on cell attachment-promoting FN fragments combined with specific elution utilizing synthetic RGD-containing peptides yielded a receptor with two 140-kDa subunits. 'The mammalian F N receptor and other RGD-directed receptors are typically heterodimers of two subunits, a and 6. '' Families of these receptors consist of members with the same or very similar /3 subunits, whereas the o( subunits are distinct and restrict the receptor's affinity to one or a few CAMS. " Collectively, these structurally and functionally related receptor families are known as the integrin superfamily. '2,'3 Nearly all mammalian cell adhesion to synthetic polymer surfaces is controlled by adsorbed proteins and is receptor-mediated. Immediately after a culture substrate is placed in a protein solution, proteins adsorb to the surface. If there are receptors for
Compression of ECG Signal Based on Compressive Sensing and the Extraction of Significant Features

Diagnoses of heart diseases can be done effectively on long term recordings of ECG signals that preserve the signals’ morphologies. In these cases, the volume of the ECG data produced by the monitoring systems grows significantly. To make the mobile healthcare possible, the need for efficient ECG signal compression algorithms to store and/or transmit the signal efficiently has been rising exponentially. Currently, ECG signal is acquired at Nyquist rate or higher, thus introducing redundancies between adjacent heartbeats due to its quasi-periodic structure. Existing compression methods remove these redundancies by achieving compression and facilitate transmission of the patient’s imperative information. Based on the fact that these signals can be approximated by a linear combination of a few coefficients taken from different basis, an alternative new compression scheme based on Compressive Sensing (CS) has been proposed. CS provides a new approach concerned with signal compression and recovery by exploiting the fact that ECG signal can be reconstructed by acquiring a relatively small number of samples in the “sparse” domains through well-developed optimization procedures. In this paper, a single-lead ECG compression method has been proposed based on improving the signal sparisty through the extraction of the signal significant features. The proposed method starts with a preprocessing stage that detects the peaks and periods of the Q, R and S waves of each beat. Then, the QRS-complex for each signal beat is estimated. The estimated QRS-complexes are subtracted from the original ECG signal and the resulting error signal is compressed using the CS technique. Throughout this process, DWT sparsifying dictionaries have been adopted. The performance of the proposed algorithm, in terms of the reconstructed signal quality and compression ratio, is evaluated by adopting DWT spatial domain basis applied to ECG records extracted from the MIT-BIH Arrhythmia Database. The results indicate that average compression ratio of 11:1 with PRD1 = 1.2% are obtained. Moreover, the quality of the retrieved signal is guaranteed and the compression ratio achieved is an improvement over those obtained by previously reported algorithms. Simulation results suggest that CS should be considered as an acceptable methodology for ECG compression.
Sensor Self-Localization for Antenna Arrays Subject to Bending and Vibrations

A method is presented for dealing with the array self-calibration problem with persistent and noncooperating narrowband sources such as TV, GSM, and radio emissions. We consider large and flexible antennas whose sensors are subject to important static distortions and dynamical vibrations. Such antennas can be found, for example, when a high-resolution array is inserted along the wings of an aircraft. We propose a self-calibration technique that solves phase ambiguities arising from the large static bending and estimates the current array shape. This two-step method can be used with a single carrier frequency or with multiband sensors. The performance of the method is evaluated with simulated data and is compared to the Cramer-Rao lower bound (CRLB).
Comparison of High Order Schemes for Large Eddy Simulation of Circular Cylinder Flow

This paper compares LES results of a cylinder flow with two sets of numerical schemes, two span lengths, and a coarse and refined mesh. One set of the numerical scheme is the 7th order WENO scheme for the inviscid fluxes and 6th order central differencing for the viscous terms (7-6), the other set is a 5th order WENO scheme with a 4th order central differencing(5-4). For this purpose, a fully conservative 6th-order central differencing for the viscous terms of compressible flows is developed. The new central differencing scheme uses the same stencil of the WENO scheme. No explicit subgrid scale models are used for the LES. The span length has a significant effect on the solution. The 5-4 scheme agrees better with the experiment with the span length of 1D and coarse mesh, whereas the 7-6 scheme performs better at the refined mesh with the span length of πD. However, both schemes have poorer results with the span length of πD.
Efficacy of pyroligneous acid from Rhizophora apiculata on pathogenic Candida albicans

Rhizophora apiculata pyroligneous acid which is a crude condensate produced from the distillation of smoke generated in the process of charcoal making has the potential to be used as antifungal agent especially to treat candidal infections. In this study, pyroligneous acid (PA), concentrated pyroligneous acid (CPA), Dichloromethane extracts of CPA namely DCM A and B were tested against four pathogenic strains of Candida albicans. The results exhibited significant inhibition zones within the range of 7.00 -8.00 mm for PA, 16.0017.00 mm for CPA, 16.00-18.00 mm for DCM A and 19.00-22.00 mm for DCM B. The results also revealed that extract DCM B of CPA was the most potential to be used as anticandidal agent with the minimum inhibitory concentration values between 3.13-6.25 mg/mL. Scanning electron micrographs of DCM B treated C. albicans cells confirmed the damaged cells caused by the extract.
Mendeley Readership Impact of Academic Articles of Iran

Introduction By means of formal citation analysis, although scientific impact of research was measured, so far other influential aspects of research such as readership and educational impact was simply ignored. Now online reference management tools such as Mendeley allow creating collections of digital paper holdings, and collaborative filtering of scientific publications, whose data proved to predict future formal citations (Li, Thelwall & Giustini, 2012). Mendeley metric obtains credit by measuring readership, for majority of users who add papers to their Mendeley libraries to read, although they may save them to cite or use in professional, educational, or teaching activities (Mohammadi, Thelwall & Kousha, in press). Mendeley readership also has potentials to present knowledge flow across fields (Mohammadi & Thelwall, 2012), and popularity of papers among users from within various countries (Maflahi & Thelwall, 2014) and academic career stages (Haustein & Larivière, 2014). Although this metric is studied for patterns of impact in various fields, its application for research impact assessment practice in developing countries is less known. Therefore, this research assessed WoS (Web of Science of Thomson Scientific) publications of Iran (20002012) for users in Mendeley across four broader research areas. In addition, career stages and nationalities of Mendeley users are also analysed for patterns of interested users in papers. The results may help to understand how and to what extent Mendeley readership metric is applicable to assess publications of authors in Iran.
Design of a 2-D magnetizer with the consideration of the z-component of the magnetic field

A magnetizer design methodology that takes into account systematic errors such as the variation in flux density (B), and the z-component of the magnetic field (Hz), is proposed. The effect of the sample diameter and the effective length of the yoke, i.e. yoke depth on Hz are analysed. Experimental results at 1.5 T and 60 Hz showed a reduction of 81 %, 72 % and 30 % by a large magnetizer, shielding and reducing the yoke depth from 80 mm to 10 mm, respectively. This was in comparison to an unshielded compact magnetizer. Hz is also dependent on magnetic loading. Furthermore, at 2 T and 60 Hz, magnetic contributions dominated Hz such that the effectiveness of shielding and reducing the yoke depth decreased to 27 % and 4 %, respectively. To achieve these very high flux densities, the magnetizers were designed to be compact (sample diameter of ≤ 100 mm and narrow airgaps of ≤ 2 mm). This reduction in size increases the leakage field above and below the sample to the same level of magnitude as the applied field, which affects the measurement of the magnetic field (H). Two H-coil sizes with a sensitivity difference of 60 % are used to show that the measured H is independent of the coil size, but depends on the leakage field. Their measured core loss difference under pulsating and rotating fields was about 6 %.
A novel double‐membrane system for simultaneous nitrification and denitrification in a single tank

A novel biological treatment system, which contains two types of membrane modules in a single tank, was developed for simultaneous nitrification and denitrification. Both of the modules were fed with the substrates on the tube side of the silicone tubes by diffusing them to the biofilms which form on the surface of the tubes. One module was fed with methanol for denitrification and the other one was fed with pure oxygen for nitrification. As a result, the interference of organic carbon on nitrification, and that of oxygen on denitrification, were both hindered by the diffusion barriers (biofilms), thereby allowing two different niches for nitrifiers and denitrifiers to coexist in a single tank. Besides saving space and the amount of alkalinity required for nitrification, this system also produced low residual chemical oxygen demand (COD) and high nitrogen removal rates (2·9 ∼ 3·4 g N m–2 d−1 of surface area of membrane).
New interface design from substrate-integrated to regular coplanar waveguide

A new design for a substrate-integrated waveguide (SIW) interfacing a regular coplanar waveguide (CPW) is reported and compared to a transition employing conductor-backed CPWs and via holed side walls. The new interface provides, first, better return loss and, secondly, larger bandwidth as demonstrated by the related modes in a dispersion diagram. The interface is optimized in an HFSS environment for single and back-to-back transition. Both single and back-to-back designs achieve more than 24 dB return loss between 18.5 GHz and 27 GHz. Their improved performances, which include dielectric and all metallic losses, are demonstrated by direct comparison with a transition involving conductor-backed CPWs and via holed side walls. Verification by CST Microwave Studio validates the designs. All dimensional parameters are specified.
CENP-A and H3 Nucleosomes Display a Similar Stability to Force-Mediated Disassembly

Centromere-specific nucleosomes are a central feature of the kinetochore complex during mitosis, in which microtubules exert pulling and pushing forces upon the centromere. CENP-A nucleosomes have been assumed to be structurally unique, thereby providing resilience under tension relative to their H3 canonical counterparts. Here, we directly test this hypothesis by subjecting CENP-A and H3 octameric nucleosomes, assembled on random or on centromeric DNA sequences, to varying amounts of applied force by using single-molecule magnetic tweezers. We monitor individual disassembly events of CENP-A and H3 nucleosomes. Regardless of the DNA sequence, the force-mediated disassembly experiments for CENP-A and H3 nucleosomes demonstrate similar rupture forces, life time residency and disassembly steps. From these experiments, we conclude that CENP-A does not, by itself, contribute unique structural features to the nucleosome that lead to a significant resistance against force-mediated disruption. The data present insights into the mechanistic basis for how CENP-A nucleosomes might contribute to the structural foundation of the centromere in vivo.
Relationships between phase morphology and deformation mechanisms in polymer nanocomposite nanofibres prepared by an electrospinning process

Relationships between phase morphology and mechanical deformation processes in various electrospun polymer nanocomposite nanofibres (PNCNFs) containing different types of one-, two- and three-dimensional nanofiller have been investigated by transmission electron microscopy using in situ tensile techniques. From the study of the phase structure of electrospun PNCNFs, two morphological standard types are classified for the analysis of deformation mechanisms: the binary system (polymer matrix and nanofillers), and the ternary system (polymer matrix, nanofillers and nanopores on the fibres surface). According to these categories, deformation processes have been characterized, and different schematic models for these processes are proposed. The finding of importance in the present work is a brittle-to-ductile transition in polymer nanocomposite fibres during in situ tensile deformation processes. This unique feature in the deformation behaviour of electrospun PNCNFs provides an optimal balance of stiffness, strength and toughness for use as reinforcing elements in a polymer based composite of a new kind.
Use of novel inhalation kinetic studies to refine physiologically-based pharmacokinetic models for ethanol in non-pregnant and pregnant rats

Abstract Ethanol (EtOH) exposure induces a variety of concentration-dependent neurological and developmental effects in the rat. Physiologically-based pharmacokinetic (PBPK) models have been used to predict the inhalation exposure concentrations necessary to produce blood EtOH concentrations (BEC) in the range associated with these effects. Previous laboratory reports often lacked sufficient detail to adequately simulate reported exposure scenarios associated with BECs in this range, or lacked data on the time-course of EtOH in target tissues (e.g. brain, liver, eye, fetus). To address these data gaps, inhalation studies were performed at 5000, 10 000, and 21 000 ppm (6 h/d) in non-pregnant female Long-Evans (LE) rats and at 21 000 ppm (6.33 h/d) for 12 d of gestation in pregnant LE rats to evaluate our previously published PBPK models at toxicologically-relevant blood and tissue concentrations. Additionally, nose-only and whole-body plethysmography studies were conducted to refine model descriptions of respiration and uptake within the respiratory tract. The resulting time-course and plethysmography data from these in vivo studies were compared to simulations from our previously published models, after which the models were recalibrated to improve descriptions of tissue dosimetry by accounting for dose-dependencies in pharmacokinetic behavior. Simulations using the recalibrated models reproduced these data from non-pregnant, pregnant, and fetal rats to within a factor of 2 or better across datasets, resulting in a suite of model structures suitable for simulation of a broad range of EtOH exposure scenarios.
