description: The elastic scattering cross sections for the reactions $^{110,116}$Cd($α,α$)$^{110,116}$Cd at energies above and below the Coulomb barrier are presented to provide a sensitive test for the alpha-nucleus optical potential parameter sets. Additional constraints for the optical potential are taken from the analysis of elastic scattering excitation functions at backward angles which are available in literature. Moreover, the variation of the elastic alpha scattering cross sections along the $Z = 48$ isotopic and $N = 62$ isotonic chain is investigated by the study of the ratios of the of $^{106,110,116}$Cd($α,α$)$^{106,110,116}$Cd scattering cross sections at E$_{c.m.} \approx$ 15.6 and 18.8 MeV and the ratio of the $^{110}$Cd($α,α$)$^{110}$Cd and $^{112}$Sn($α,α$)$^{112}$Sn reaction cross sections at E$_{c.m.} \approx$ 18.8 MeV, respectively. These ratios are sensitive probes for the alpha-nucleus optical potential parameterizations. The potentials under study are a basic prerequisite for the prediction of $α$-induced reaction cross sections, e.g.\ for the calculation of stellar reaction rates in the astrophysical $p$- or $γ$-process.

description: The study of symbiotic systems is of considerable importance in our understanding of binary system stellar evolution in systems where mass loss or transfer takes place. Elemental abundances are of special significance since they can be used to track mass exchange. However, there are few symbiotic giants for which the abundances are fairly well determined. Here we present for the first time a detailed analysis of the chemical composition for the giants in the RW Hya and SY Mus systems. The analysis is based on high resolution (R 50000), high S/N, near-IR spectra. Spectrum synthesis employing standard LTE analysis and atmosphere models was used to obtain photospheric abundances of CNO and elements around the iron peak (Sc, Ti, Fe, and Ni). Our analysis reveals a significantly sub-solar metallicity, [Fe/H]-0.75}, for the RW Hya giant confirming its membership in the Galactic halo population and a near-solar metallicity for the SY Mus giant. The very low 12C/13C isotopic ratios, 6-10, derived for both objects indicate that the giants have experienced the first dredge-up

Distributed Compressive CSIT Estimation and Feedback for FDD Multi-user Massive MIMO Systems

description: To fully utilize the spatial multiplexing gains or array gains of massive MIMO, the channel state information must be obtained at the transmitter side (CSIT). However, conventional CSIT estimation approaches are not suitable for FDD massive MIMO systems because of the overwhelming training and feedback overhead. In this paper, we consider multi-user massive MIMO systems and deploy the compressive sensing (CS) technique to reduce the training as well as the feedback overhead in the CSIT estimation. The multi-user massive MIMO systems exhibits a hidden joint sparsity structure in the user channel matrices due to the shared local scatterers in the physical propagation environment. As such, instead of naively applying the conventional CS to the CSIT estimation, we propose a distributed compressive CSIT estimation scheme so that the compressed measurements are observed at the users locally, while the CSIT recovery is performed at the base station jointly. A joint orthogonal matching pursuit recovery algorithm is proposed to perform the CSIT recovery, with the capability of exploiting the hidden joint sparsity in the user channel matrices. We analyze the obtained CSIT quality in terms of the normalized mean absolute error, and through the closed-form expressions, we obtain simple insights into how the joint channel sparsity can be exploited to improve the CSIT recovery performance.

description: In this paper we study the structure of complex points of codimension 2 real submanifolds in complex $n$ dimensional manifolds. We show that the local structure of a complex point up to isotopy only depends on their type (either elliptic or hyperbolic). We also show that any such submanifold can be smoothly isotoped into a submanifold that has 2-strictly pseudoconvex neighborhood basis.
Ripening and Focusing of Aggregate Size Distributions with Overall Volume Growth

description: We explore the evolution of the aggregate size distribution in systems where aggregates grow by diffusive accretion of mass. Supersaturation is controlled in such a way that the overall aggregate volume grows linearly in time. Classical Ostwald ripening, which is recovered in the limit of vanishing overall growth, constitutes an unstable solution of the dynamics. In the presence of overall growth evaporation of aggregates always drives the dynamics into a new, qualitatively different growth regime where ripening ceases, and growth proceeds at a constant number density of aggregates. We provide a comprehensive description of the evolution of the aggregate size distribution in the constant density regime: the size distribution does not approach a universal shape, and even for moderate overall growth rates the standard deviation of the aggregate radius decays monotonically. The implications of this theory for the focusing of aggregate size distributions are discussed for a range of different settings including the growth of tiny rain droplets in clouds, as long as they do not yet feel gravity, and the synthesis of nano-particles and quantum dots.

description: La salle des maîtres est dans un collège un lieu à part, soumis à des règles sociales différentes que le reste de l’établissement. Les utilisateurs de cet endroit spécifique y respectent leur propre règlement, tacite et social, et utilisent cette salle pour travailler, manger, discuter, partager et observer. En permanence seul face aux élèves, l’enseignant ne retrouve d’autres adultes qu’en salle des maîtres, lors d’un moment de pause et de détente. C’est à ce moment-là que vont se tenir des propos sur les élèves, chaque enseignant ayant besoin de partager et de comparer son expérience, tout en utilisant la salle des maîtres comme « sas de décompression » face aux problèmes rencontrés en classe. Les propos qui seront alors tenus en salle des maîtres vont rester tus dans le cadre du secret professionnel, mais marqueront les esprits des jeunes enseignants ou des stagiaires. Quel impact va avoir ces propos sur les futurs enseignants ? Peut-on, en tant que professeur, véritablement tout dire en salle des maîtres ? À travers l’analyse de sept différents témoignages recueillis dans des salles des maîtres du canton de Vaud, et de la comparaison entre expérience réellement vécue et théories sociologiques, ce travail va tenter de définir les règles tacites de la salle des maîtres, son utilisation et les comportements autorisés et acceptés en ce lieu si particulier.

description: Network-on-chip (NoC) architectures have been proposed as a promising alternative to classical bus-based communication architectures. In this paper, we propose a two phases framework to solve application-specific NoCs topology generation problem. At floorplanning phase, we carry out partition driven floorplanning. At post-floorplanning phase, a heuristic method and a min-cost max-flow algorithm is used to insert switches and network interfaces. Finally, we allocate paths to minimize power consumption. The experimental results show our algorithm is effective for power saving.

description: We discuss the possible implication of the recent predictions of two new properties of high momentum distribution of nucleons in asymmetric nuclei for neutron star dynamics. The first property is about the approximate scaling relation between proton and neutron high momentum distributions weighted by their relative fractions ($x_p$ and $x_n$) in the nucleus. The second is the existence of inverse proportionality of the high momentum distribution strength of protons and neutrons to $x_{p/n}$. Based on these predictions we model the high momentum distribution functions for asymmetric nuclei and demonstrate that it describes reasonably well the high momentum characteristics of light nuclei. We also extrapolate our results to heavy nuclei as well as infinite nuclear matter and calculate the relative fractions of protons and neutrons with momenta above $k_{F}$. Our results indicate that for neutron stars starting at {\em three} nuclear saturation densities the protons with $x_p = {1\over 9}$ will populate mostly the high momentum tail of the momentum distribution while only $2\%$ of the neutrons will do so. Such a situation may have many implications for different observations of neutron stars which we discuss.

description: We study the time evolution of the impact probability for synthetic but realistic impacting and close approaching asteroids detected in a simulated all-sky survey. We use the impact probability to calculate the impact warning time as the time interval between when an object reaches a Palermo Scale value of -2 and when it impacts Earth. A simple argument shows that warning time ~ D^x with the exponent in the range [1.0,1.5] and our derived value was $x=1.3\pm0.1$. The low-precision astrometry from the single simulated all-sky survey could require many days or weeks to establish an imminent impact for asteroids >100m diameter that are discovered far from Earth. Most close approaching asteroids are quickly identified as not being impactors but a size-dependent percentage, even for those >50m diameter, have a persistent impact probability of >10^{-6} on the day of closest approach. Thus, a single all-sky survey can be of tremendous value in identifying Earth impacting and close approaching asteroids in advance of their closest approach but it can not solve the problem on its own: high-precision astrometry from other optical or radar systems is necessary to rapidly establish an object as an impactor or close approacher. We show that the parallax afforded by surveying the sky from two sites is only of benefit for a small fraction of the smallest objects detected within a couple days before impact: probably not enough to justify the increased operating costs of a 2-site survey. Finally, the survey cadence within a fixed time span is relatively unimportant to the impact probability calculation. We tested three different reasonable cadences and found that one provided ~10x higher (better) value for the impact probability on the discovery night for the smallest (10m diameter) objects but the consequences on the overall impact probability calculation is negligible.

Year: 2014

description: Certain advantages of service-oriented architecture have led to the spread of this type of architecture around the world. However, some special features of this type of architecture have led to more compromise between the security in the information system and other information systems. The purpose of this paper is to identify and examine the impact of factors and dimensions of the information security system that has developed by using service-oriented architecture. In this study, the exploratory and confirmatory factor analyses have been used to identify overt and covert variables. Then, a structured equation model and AMOS software have been used. Finally, the effect of each security dimension of security service-oriented architecture was specified by using the structural equation model. The results indicate that network-level security, web services and message-level security have a significant positive impact on service-oriented architecture. The software output is indicative of the fact that the structured model is fit.

Algebraic probability theory and Lie algebraic treatments make it easy to treat the time-inhomogeneous cases. As a result, an expression based on the Charlier polynomials is obtained, which can be considered as an extension of a famous Karlin-KcGregor representation for a time-homogeneous birth-death process.

Proposing a Model for Successful Application of Knowledge Sharing II (Social Knowledge Sharing) within Organizations
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2014

description: The main purpose of this research is the development of a success model of Knowledge Sharing 2.0 (social knowledge sharing) through organizations. A three-step strategy is used in this research as stated below: In the first step, identification of social software and extraction of factors effective on success of each for knowledge sharing were obtained from literature review. Execution of Delphi method and identification of critical factors were done in the second step. At last, in the third step, a success model was developed based on the obtained results. According to the results obtained from this study, the most important social software in order of their importance for knowledge sharing along with the most significant success factor of each in knowledge sharing are known to be: social network software (the most important critical success factor: active presence of experts and influential individuals in the desired field of knowledge in the social network), weblog software (the most important critical success factor: quality of existing information in the weblog), wiki software (the most important critical success factor: wiki configuration based on key fields of knowledge in organization), podcast software (the most important critical success factor: extent of applicability and practicality of the podcast contents), mashup software (the most important critical success factor: quality of information from mashup sources), tag software (the most important critical success factor: regular and intelligent updating) and RSS software (the most important critical success factor: continuous updating-7×24). Based on the information available for the researchers, originality and innovation of the current work stem from two viewpoints: first, development of the critical success factors of the social software for knowledge sharing and second, development of the success model of Knowledge Sharing 2.0. The proposed model can be used as an appropriate tool for evaluation of success, assessment of status, prediction and related pathologies in connection with establishment of Knowledge Sharing 2.0 in organizations.

Le moyen d’enseignement ayant été élaboré à la suite du PER, on s’attend donc à ce qu’il réponde à toutes les exigences du plan d’étude. C’est ce que j’ai cherché à vérifier au travers de ce travail. L’apprentissage des sciences étant autant un processus que l’acquisition de connaissances, il est nécessaire de se pencher sur ces deux aspects. Dans les faits, on constate que la démarche scientifique est très bien travaillée au court de ces séquences. En revanche, il y a une grosse lacune pour tout ce qui concerne la prévention au niveau de la santé. Certaines attentes fondamentales ne sont que partiellement couvertes. Notamment la distinction entre le mécanisme de ventilation et la respiration cellulaire et la distinction de ce qui n’est pas absorbé par le système digestif et les déchets du métabolisme éliminés par les reins. Afin d’établir comment le MER satisfait aux exigences du PER, l’analyse de différents tableaux et graphiques de synthèse a été discutée.

description: A periodic information needs assessment in libraries and information centers will allow libraries to focus on providing access to the most appropriate resources for specific groups and increase users satisfaction and library effectiveness. The present research paper, which is an applied survey, focuses on the subjects’ attitude towards factors affecting information needs assessment in academic libraries. Research population included 190 subjects from 29 medical and non-medical academic libraries who were asked to fill-in a research-made questionnaire. The results showed that 70 percent of the surveyed libraries had never undertaken a systematic information needs assessment. Some of the significant factors affecting information needs assessment were: managerial commitment to identifying users’ information needs, postulation of user needs, managing s resistance to change, paying no attention to reality and policy. The tests showed meaningful differences among the subjects attitudes relating to their demographic variables also the test indicated no significant differences between the attitudes towards the barriers of information needs assessment.

description: Log analysis or Web transactions Log are beneficial for enhancing information retrieval systems, productivity of the system for users, and understanding how users benefited from a system and their information behavior. The purpose of this paper is to analyze users’ behavior, the level of their using IRANDOC database and the way they use it. In order to do this, the users log to the database from outside IRANDOC searching information was studied for a period of 24 days in Bahman and Esfand 1391. The analysis of users log includes: geographic coding analysis, statistical analysis, and microanalysis of information seeking behavior. The results indicate that users from the cities of Tehran, Mashhad and Tabriz used the database more than other cities. Sundays and Mondays between 9 to13 were the peak use days and hours. 10 to 15 search characters long were the most frequently used search items, and the most searched subject was Social Sciences. The findings showed also that some users were not familiar with concepts like search term modification and how to use Boolean operators which resulted in inefficient information retrieval. Inefficient retrieval algorithm for short words was also found in the database. It was also found that log analysis can be of use in the evaluation of an information retrieval system as well as in user behavior analysis.

description: We study entanglement entropy in two-dimensional conformal field theories with a gravitational anomaly. In theories with gravity duals, this anomaly is holographically represented by a gravitational Chern-Simons term in the bulk action. We show that the anomaly broadens the Ryu-Takayanagi minimal worldline into a ribbon, and that the anomalous contribution to the CFT entanglement entropy is given by the twist in this ribbon. The entanglement functional may also be interpreted as the worldline action for a spinning particle -- that is, an anyon -- in three-dimensional curved spacetime. We demonstrate that the minimization of this action results in the Mathisson-Papapetrou-Dixon equations of motion for a spinning particle in three dimensions. We work out several simple examples and demonstrate agreement with CFT calculations.

Analysis of Researchers’ Information Searching Behavior Based on Verbal/ Imagery Cognitive Styles on Web
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2014

description: The purpose of this study is to investigate the effects of verbal and imagery cognitive styles on information searching behavior of users in using the Web. Applied and mixed method was used in this study. Forty-four participants, including academic staff from Iranian universities and research centers were recruited for this study. Participants’ cognitive style was measured by using Riding Cognitive Style Analysis test. Two search tasks were designed based on Kim’s search task definitions. An individual lab session was arranged and then each participant’s memos were analyzed using a constructive observation approach. 48 strategies in 4 categories were identified: search initiation behaviors, formulating search queries, search conducting behaviors, and information processing behaviors. It was found that there were relations between users’ cognitive styles and information searching behavior. The participants varied in their selection of search initiation behaviors so that imagers suffered from more varied initial behavior than verbalizers. Verbalizers tended to search in narrow area then broadening the area and follow structured conduction and reading behavior to process information, while imagers tended to search in general area then narrowing down the search and adopt mix conductional styles and mixed behavior to process information. Results showed that both descriptively and statistically there were significant difference between information searching behavior of imagers and verbalizers, so that verbalizers used more strategies than imagers. Findings noted that verbalizers spent more time than imagers for completing tasks, whereas imagers tended to visit more nodes than did the verbalizers. Significant interaction was found between types of search task in number of nodes visited and time spent in retrieving information, but statistically there was no significant difference between cognitive styles, and between types of search task and cognitive styles in number of nodes visited and time spent in retrieving information. The study provides new understanding of Web users’ information search behavior based on cognitive styles which contributes to the theoretical basis of Web search research. It also raises various questions within the context of user studies. The paper adopted a qualitative approach in the area of information searching on the Web which is mainly dominated by research methods.

description: Magnetohydrodynamic (MHD) instabilities can play an important role in the dynamics of the pulsar magnetosphere and can be responsible for the formation of various structures. We consider the instability caused by a gradient of the magnetic pressure which can occur in a non-neutral magnetospheric plasma. We arguethat the pulsar magnetospheres are always unstable. The unstable disturbances have a form of filaments directed along the magnetic field lines with plasma motions being almost parallel (or anti-parallel) to the magnetic field. The growth rate of instability is high and can reach a fraction of $ck$, where $k$ is the wavevector of unstable disturbances. The instability can be responsible for fluctuations of plasma and the short-term variability of pulsar emission.

description: The evaluation of produced items at the time of delivery is, in practice, usually amended by at least one inspection at later time points. We extend the methodology of acceptance sampling for variables for arbitrary unknown distributions when additional sampling infor- mation is available to such settings. Based on appropriate approximations of the operating characteristic, we derive new acceptance sampling plans that control the overall operating characteristic. The results cover the case of independent sampling as well as the case of dependent sampling. In particular, we study a modified panel sampling design and the case of spatial batch sampling. The latter is advisable in photovoltaic field monitoring studies, since it allows to detect and analyze local clusters of degraded or damaged modules. Some finite sample properties are examined by a simulation study, focusing on the accuracy of estimation.

description: This study focused on the Men’s and Women’s World Cup looking into how gender is constructed within the commentary from the 2014 & 2015 tournaments. Football was used because football had been examined in a number of different ways, such as participation rates or newspaper coverage, but commentary hadn’t been analysed in this way before. Using a combination of commentary and match reports, the narratives of the commentary was analysed to find out if there were any stylistic techniques that differed between the two sets of commentary.These tournaments were used because of their proximity to each other and only at the group stages to keep as much continuity between the two sets of commentary as possible. A Foucauldian Discourse analysis was used to examine the World Cup match commentary because of its focus on the ideological content of language. This study found that there were notable differences in the narratives between the men’s and women’s matches.The results showed that the historical impact of the men’s game related to it being thenation’s favourite sport. Men also build the image of a nation in relation to football as a symbol of England, with women taking a secondary place in football. The structure of the women’s match commentary led them to be overtly feminized, the narratives in the women’s games exaggerated stereotypical feminine qualities, such as reference to family and personal stories. These findings demonstrated a need for change in the way men’s and women’s match commentary is structured and delivered. There has already been a staggering change in the growth and perception of the women’s game, but for the two to be considered equal, thereare still hurdles that need to be overcome.

description: Network vulnerability taxonomy has become increasingly important in the area of information and data exchange not only for its potential use in identification of vulnerabilities but also in their assessment and prioritization. Computer networks play an important role in information and communication infrastructure. However, they are constantly exposed to a variety of vulnerability risks. In their attempts to create secure information exchange systems, scientists have concentrated on understanding the nature and typology of these vulnerabilities. Their efforts aimed at establishing secure networks have led to the development of a variety of methods and techniques for quantifying vulnerability. The objective of the present paper is developing a method based on the second edition of common vulnerability scoring system (CVSS) for the quantification of Computer Network vulnerabilities. It is expected that the proposed model will help in the identification and effective management of vulnerabilities by their quantification.

description: Over the past two decades, social media have become a crucial and omnipresent cultural and economic phenomenon, which has seen platforms come and go and advance technologically. In this study, we explore the further development of social media regarding interactive technologies, platform development, relationships to news media, the activities of institutional and organizational users, and effects of social media on the individual and the society over the next five to ten years by conducting an international, two-stage Delphi study. Our results show that enhanced interaction on platforms, including virtual and augmented reality, somatosensory sense, and touch- and movement-based navigation are expected. AIs will interact with other social media users. Inactive user profiles will outnumber active ones. Platform providers will diversify into the WWW, e-commerce, edu-tech, fintechs, the automobile industry, and HR. They will change to a freemium business model and put more effort into combating cybercrime. Social media will become the predominant news distributor, but fake news will still be problematic. Firms will spend greater amounts of their budgets on social media advertising, and schools, politicians, and the medical sector will increase their social media engagement. Social media use will increasingly lead to individuals’ psychic issues. Society will benefit from economic growth and new jobs, increased political interest, democratic progress, and education due to social media. However, censorship and the energy consumption of platform operators might rise.

description: High fidelity quantum control over qubits is of crucial importance for realistic quantum computing, and it turns to be more challenging when there are inevitable interactions among qubits. By employing a bandselective shaped pulse, we demonstrate a high fidelity flip over electron spin of nitrogen-vacancy (NV) centers in diamond. In contrast with traditional rectangular pulses, the shaped pulse has almost equal excitation effect among a sharply edged region (in frequency domain). So the three sub-levels of host $^{14}N$ nuclear spin can be flipped accurately at the same time, while the redundant flip of other sublevels (e. g. of a nearby $^{13}C$ nuclear spin ) is well suppressed. The shaped pulse can be applied to a large amount of quantum systems in which band-selective operation are required.

Evaluation of the Efficiency of Cloud Computing Models in E-learning Services
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2014

description: Although web-based learning has a lot of advantages over other commonly used technologies in the field, it has its own challenges, too. For example, due to lack of scalability at the infrastructure level, the cost of resource management in e-learning systems has increased significantly. Another example is how to achieve efficient resource utilization in these systems. In addition to dealing with these challenges, other costs should be incurred to provide e-learning services, such as maintenance cost of website, and the associated costs with installation and technical support of software packages. In this paper, we discuss that designing e-learning systems based on cloud computing models is an appropriate approach to dealing with the mentioned challenges. To this end, after an introduction to cloud computing models, we design the architecture of an e-learning system based on the models. Then, we implement the proposed architecture using CloudSim as a simulation tool to evaluate the efficiency of the system. The results demonstrate that by taking the proposed approach, while the system achieves an efficient resource utilization, the scalability of e-learning services increases as well.
Comparing MCQ with JIF2 and JIF5 for Mathematical Journals
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2014

description: The purpose of this paper is to compare Mathematical Citation Quotient (MCQ), as a tool of mathematical science citation analysis, with Journal Impact Factor (JIF) in both 2-year and 5-year impact factors. MCQ is represented in the 2005 version of MathSciNet with special selected journals named as the Reference List Journals (RLJ). This study is an investigation of pure mathematics journals listed in JCR database. A comparison of the relative overlap for the journals shows that relative overlap of RLJ in JCR is equal to 72.2 percent. In this research, MCQ has been compared with JIF2 and JIF5. The average of JIF2 and JIF5 are higher than the average of journals' MCQ. Comparison of correlations shows that in general MCQ has a strong and direct correlation with JIF2 and JIF5, but when journals are put in deciles, we get different results. By comparing averages we show that in any deciles, averages of JIF2 and JIF5 are more than MCQ. In some deciles, we have various correlations and even negative ones. A comparison between MCQ and JIF2 shows that only in the first deciles the correlation is strong and direct and in the deciles 2, 7 and 8, there is a weak direct correlation. In the other deciles one observes some negative correlations. A comparison between MCQ and JIF5 shows that the correlation is strong only in the first deciles and direct and in the others there are weak correlations, in particular, in deciles 6, 8, 9 and 10 the correlations are negative. This article advises American Mathematical Society to extend the coverage of RLJ and suggest pure mathematics departments to take care of usage of JIF2, rather MCQ may be a good source for evaluating researches of their academic members.
