description: The native three dimensional structure of a single protein is determined by the physico chemical nature of its constituent amino acids. The twenty different types of amino acids, depending on their physico chemical properties, can be grouped into three major classes - hydrophobic, hydrophilic and charged. We have studied the anatomy of the weighted and unweighted networks of hydrophobic, hydrophilic and charged residues separately for a large number of proteins. Our results show that the average degree of the hydrophobic networks has significantly larger value than that of hydrophilic and charged networks. The average degree of the hydrophilic networks is slightly higher than that of charged networks. The average strength of the nodes of hydrophobic networks is nearly equal to that of the charged network; whereas that of hydrophilic networks has smaller value than that of hydrophobic and charged networks. The average strength for each of the three types of networks varies with its degree. The average strength of a node in charged networks increases more sharply than that of the hydrophobic and hydrophilic networks. Each of the three types of networks exhibits the 'small-world' property. Our results further indicate that the all amino acids' networks and hydrophobic networks are of assortative type. While maximum of the hydrophilic and charged networks are of assortative type, few others have the characteristics of disassortative mixing of the nodes. We have further observed that all amino acids' networks and hydrophobic networks bear the signature of hierarchy; whereas the hydrophilic and charged networks do not have any hierarchical signature.

description: Aspect-Oriented Software Development (AOSD) is a promising methodology for efficiently capturing the cross-cutting functionalities (concerns) as independent units called aspects. Inheritance of classes and aspects play a vital role in defining the units of encapsulation. Hence, it is essential to quantitatively capture the impact of inheritance in AOSD using design level metrics and to infer on the higher level quality attribute, reusability. An application to automate the processes of a typical University has been developed in order to study the effect of using inheritance over the versions of an aspectized AO application. A set of metrics to capture the manifestations of inheritance is proposed for measurement. An automated tool named as Aspect Oriented Software Reusability Measurement AOSRM is also designed and developed to calculate the values of the proposed metrics. Based on the obtained metric values for Java and AspectJ versions of the case study application, inheritance in AspectJ versions showed a positive impact on reusability of software.

description: The long-distance electromagnetic radiative corrections to tau- -> pi- pi0 nu are re-evaluated. A meson dominance model is used to describe the emission of real photons in this decay. Results obtained for the hadronic spectrum and the decay rate in photon inclusive reactions are compared with previous calculations based on the chiral resonance theory. Independent tests in tau -> pi pi nu gamma that can help to validate the predictions of one of the two models are briefly discussed.

description: Inspired by recent experiments on fully spin polarized Na clusters, we perform a systematic survey of neutral Na clusters at all conceivable spin polarizations. We study the impact of spin state on ionic configuration, on global shape, and on optical response. For small clusters, the magic electronic shell at 4 spin-up electrons is a dominating feature leading to preferred binding for all clusters having four spin-up electrons (combined with 1 to 4 spin-down electrons). Such a preference fades away for larger systems where the unpolarized state is generally preferred.
How males are portrayed in realistic juvenile fiction and how this portrayal has changed over the past twenty years
Creators: name: Valens, Mark Allan
Publisher: name: University of British Columbia
Year: 2009

description: This research investigated how males are portrayed in realistic juvenile fiction and how this portrayal has changed over the past twenty years. A deconstructionist approach was taken to analyze the primary male characters in award winning realistic juvenile fiction. The researcher used a three-step approach to analyze the primary male characters in the books. First, templates with identified characteristics were used to categorize various features of all the primary characters. Second, characteristics occurring repeatedly were identified, grouped and labeled. These were defined as "Codes" and are the areas through which primary characters are portrayed in realistic juvenile fiction. The codes identified were: "Conflict Resolution," "Emotions," "Race," "Relationships," and "Success." Third, features specific to primary male characters that were found within the codes were identified and discussed. Results showed that male characters are portrayed in a positive light, but that this portrayal is narrow in its scope. Men are portrayed more narrowly and stereotypically than are boys. The change over the past twenty years has been minimal, but males have become more multidimensional in realistic juvenile fiction during the past ten years.

Motivation for the Study

UEFISCDI has recently developed its institutional Action Plan for CoARA (available here), and this study was carried out in parallel as a learning and evidence-gathering process. The selection of cases—FNR Luxembourg, Universities of the Netherlands (UNL), DFG Germany, and the European Research Council (ERC)—reflects an intention to include both research funding organizations and research-performing institutions, offering a diversity of perspectives and implementation contexts.

The primary motivation behind this review is to inform research communities and policymakers by presenting tested practices, reform approaches, and lessons learned from pioneering organizations in the field. By analyzing these cases, UEFISCDI aims to support the transition toward research assessment systems that better reflect the diversity of research contributions, career paths, and societal relevance of scientific work.

Through structured interviews and desk research, this study sheds light on how different actors have approached reform—what has worked, what challenges were encountered, and what impact the changes have had so far. The hope is that these insights will inspire and guide future reform initiatives at different levels across Romania and beyond.

description: Light-engineering of quantum materials via electromagnetic dressing is considered an on-demand approach for tailoring electronic band dispersions and even inducing topological phase transitions. For probing such dressed bands, photoemission spectroscopy is an ideal tool, and we employ here a novel experiment based on ultrafast photoemission momentum microscopy. Using this setup, we measure the in-plane momentum-dependent intensity fingerprints of the electromagnetically-dressed sidebands from a Au(111) surface for s- and p-polarized infrared driving. We find that at metal surfaces, due to screening of the driving laser, the contribution from Floquet-Bloch bands is negligible, and the dressed bands are dominated by the laser-assisted photoelectric effect. Also, we find that in contrast to general expectations, s-polarized light can dress free-electron states at large photoelectron momenta. Our results show that the dielectric response of the material must carefully be taken into account when using photoemission for the identification of light-engineered electronic band structures.

Η μελέτη της ροής γίνεται για δυο αριθμούς Reynolds 250 και 500.Ο λόγος που επιλέχτηκαν μικροί αριθμοί Re είναι ότι δεν υπάρχει εκτεταμένη έρευνα γύρω από αυτούς. Το μοντέλο επιλύεται αριθμητικά με την βοήθεια H/Y και με την μέθοδο των πεπερασμένων στοιχείων. Τα αποτελέσματα συγκρίνονται με πειραματικά και υπολογιστικά αποτελέσματα άλλων ερευνητών.
description: In this thesis is studied the dimensional, unsteady, turbulent airflow around rural construction, simulating the flow dynamics in a wind tunnel with a mathematical model of fluid viscosity, using the Navier-Stokes equations and the equation of continuity with specific boundary conditions. The study of flow is for two numbers Reynolds 250 and 500. The study has been chosen to be done for small Re numbers because extensive research around them doesn’t exist. The model is solved numerically by means of H / Y and the finite element method. The results are compared with experimental and computational results of other researchers.

description: The generalized oscillator strengths (GOS) of discrete excitations np-nd, both dipole (L=1) and octupole (L=3) are studied, the latter for the first time. We demonstrate that although the relevant transitions in the same atom are closely located in energy, the dependence of their GOS on the momentum transfer q squared, is remarkably different, so that the GOS corresponding to L=3 have at least one extra maximum as a function of q squared and dominate over those of the L=1, starting from about q=1.25$ atomic unit (a.u.). The calculations were performed in the one particle Hartree-Fock approximation and with account of many-electron correlations via the Random Phase Approximation with Exchange. The GOS are studied for values of q squared up to 30 a.u.

The Physics and Early History of the Intergalactic Medium

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The intergalactic medium - the cosmic gas that fills the great spaces between the galaxies - is affected by processes ranging from quantum fluctuations in the very early universe to radiative emission from newly-formed stars. This gives the intergalactic medium a dual role as a powerful probe both of fundamental physics and of astrophysics. The heading of fundamental physics includes conditions in the very early universe and basic cosmological parameters. The astrophysics refers to chapters of the long cosmic history of stars and galaxies that are being revealed through the effects of stellar feedback on the cosmic gas. This review describes the physics of the intergalactic medium, focusing on recent theoretical and observational developments in understanding early cosmic history. In particular, radiation from the earliest generation of stars is thought to have transformed the universe, turning the surrounding atoms into free electrons and ions. Knowing exactly when and how the reionization process happened is a primary goal of cosmologists, because this would tell us when the early stars and black holes formed and in what kinds of galaxies. Cosmic reionization is beginning to be understood with the help of theoretical models and computer simulations. A wide variety of instruments currently under design will probe the first sources of light during an epoch in cosmic history that has been largely unexplored so far. The new observations and the challenges for theoretical models and numerical simulations will motivate intense work in this field over the coming decade. (abridged)

description: The present study investigated the effects of multiple foreign languages learning on short-term memory, working memory capacity and on executive function abilities. Two groups of participants, a monolingual group (N = 67) and a polyglot group (N = 65) of adults who had learned several foreign languages, compared on their short-term and working memory capacity and on their executive functions. Specifically, we estimated their verbal and visual working memory, their phonological and visual short-term memory and their inhibition, switching and updating abilities. Results revealed that the two groups differed significantly on all their executive function abilities (inhibition, switching and updating) and on their ability to retain visual and verbal material in their short-term memory, with polyglot group being more advanced. Nevertheless, no significant differences found on working memory capacity. The results suggest that the beneficial effects of foreign language learning might be more evident on executive functions rather on working memory.

description: Cloud computing and distributed computing are becoming ubiquitous in many modern control systems such as smart grids, building automation, robot swarms or intelligent transportation systems. Compared to "isolated" control systems, the advantages of cloud-based and distributed control systems are, in particular, resource pooling and outsourcing, rapid scalability, and high performance. However, these capabilities do not come without risks. In fact, the involved communication and processing of sensitive data via public networks and on third-party platforms promote, among other cyberthreats, eavesdropping and manipulation of data. Encrypted control addresses this security gap and provides confidentiality of the processed data in the entire control loop. This paper presents a tutorial-style introduction to this young but emerging field in the framework of secure control for networked dynamical systems.

description: We address the problem of the response to a seismic wave of an urban site consisting of $N$ non-identical, non-equispaced blocks overlying a soft layer underlain by a hard substratum. The results of a theoretical analysis, appealing to a space-frequency mode-matching (MM) technique, are compared to those obtained by a space-time finite element (FE) technique. The two methods are shown to give rise to the same prediction of the seismic response for N=1 and N=2 blocks. The mechanism of the interaction between blocks and the ground, as well as that of the mutual interaction between blocks, are studied. It is shown that the presence of a small number of blocks modifies the seismic disturbance in a manner which evokes qualitatively, but not quantitatively, what was observed during the 1985 Michoacan earthquake in Mexico City. Disturbances at a much greater level, induced by a large number of blocks (in fact, a periodic set) are studied in the companion paper.

We further analyze comparative statics of the stationary equilibrium by quantitatively determining the impact of the effort cost.

description: We present theoretical calculations of orientation-dependent total ionization yields from the highest occupied molecular orbitals of the oriented OCS molecule by solving the time-dependent Schrödinger equation in three dimensions. The calculations were performed within the single-active-electron approximation including multielectron polarization. The multielectron polarization term was represented by an induced dipole term which contains the polarizability of the OCS + cation parallel to the laser polarization. Upon accounting for multielectron polarization, the calculated total ionization yields and their orientation dependence are in good agreement with experimental data.

description: In the limit of heavy quark masses going to infinity, a symmetry is known to emerge in QCD relating properties of hadrons with two heavy quarks to analogous states with one heavy anti-quark. A key question is whether the charm mass is heavy enough so that this symmetry is manifest in at least an approximate manner. The issue is crucial in attempting to understand the recent reports by the SELEX Collaboration of doubly charmed baryons. We argue on very general grounds that the charm quark mass is substantially too light for the symmetry to emerge automatically via colour coulombic interactions. However, the symmetry could emerge approximately depending on the dynamical details.

description: We consider a nonlinear Robin problem driven by the sum of $p$-Laplacian and $q$-Laplacian (i.e. the $(p,q)$-equation). In the reaction there are competing effects of a singular term and a parametric perturbation $λf(z,x)$, which is Carathéodory and $(p-1)$-superlinear at $x\in\mathbb{R},$ without satisfying the Ambrosetti-Rabinowitz condition. Using variational tools, together with truncation and comparison techniques, we prove a bifurcation-type result describing the changes in the set of positive solutions as the parameter $λ>0$ varies.

description: Software metric plays a vital role in quantitative assessment of any specific software development methodology and its impact on the maintenance of software. It can also be used to indicate the degree of interdependence among the components by providing valuable feedback about quality attributes such as maintainability, modifiability and understandability. The effort for software maintenance normally has a high correlation with the complexity of its design. Aspect Oriented Software Design is an emerging methodology that provides powerful new techniques to improve the modularity of software from its design. In this paper, evaluation model to capture the symptoms of complexity has been defined consisting of metrics, artifacts and elements of complexity. A tool to automatically capture these metrics across different versions of a case study application, University Automation System has been developed. The values obtained for the proposed metrics are used to infer on the complexity of Java and AspectJ implementations of the case study application. These measurements indicate that AspectJ implementations are less complex compared to the Java implementations and there by positively influencing the maintainability of software.
A Moving Discontinuous Galerkin Finite Element Method with Interface Conservation Enforcement for Compressible Flows

description: A moving discontinuous Galerkin finite element method with interface conservation enforcement (MDG+ICE) is developed for solving the compressible Euler equations. The MDG+ICE method is based on the space-time DG formulation, where both flow field and grid geometry are considered as independent variables and the conservation laws are enforced both on discrete elements and element interfaces. The element conservation laws are solved in the standard discontinuous solution space to determine conservative quantities, while the interface conservation is enforced using a variational formulation in a continuous space to determine discrete grid geometry. The resulting over-determined system of nonlinear equations arising from the MDG+ICE formulation can then be solved in a least-squares sense, leading to an unconstrained nonlinear least-squares problem that is regularized and solved by Levenberg-Marquardt method. A number of numerical experiments for compressible flows are conducted to assess the accuracy and robustness of the MDG+ICE method. Numerical results obtained indicate that the MDG+ICE method is able to implicitly detect and track all types of discontinuities via interface conservation enforcement and satisfy the conservation law on both elements and interfaces via grid movement and grid management, demonstrating that an exponential rate of convergence for Sod and Lax-Harden shock tube problems can be achieved and highly accurate solutions without overheating to both double-rarefaction wave and Noh problems can be obtained.

description: The Belle II experiment at the SuperKEKB energy-asymmetric e+e− collider is a substantial upgrade of the B factory facility at the Japanese KEK laboratory. The design luminosity of the machine is 8×1035 cm−2s−1 and the Belle II experiment aims to record 50 ab−1 of data, a factor of 50 more than its predecessor. From February to July 2018, the machine has completed a commissioning run, achieved a peak luminosity of 5.5×1033 cm−2s−1, and Belle II has recorded a data sample of about 0.5 fb−1. Main operation of SuperKEKB has started in March 2019.. Already this early data set with specifically designed triggers offers the possibility to search for a large variety of dark sector particles in the GeV mass range complementary to LHC and dedicated low energy experiments; these searches will benefit from more data in the process of being accumulated. This talk will review the state of the dark sector searches at Belle II with a focus on the discovery potential of the early data.

description: We studied the charge radius ($r_{c}$), neutron radius ($r_n$), and neutron skin-thickness ($Δr=r_n-r_p$) over a chain of isotopes from C to Zr with the stable region to the neutron drip line. Theoretical calculations are done with axially deformed self-consistent relativistic mean-field theory (RMF) with effective nonlinear NL3 and NL3* interactions. The theoretically estimated values are compared with available experimental data and a reasonable agreement are noted. We additionally assessed the two-neutron separation energy ($S_{2n}$) to mark the drip line nuclei of the considered isotopic series. In the reference of $S_{2n}$, neutron magicity is also discussed. The calculated neutron radii are compared with empirical estimation made by $r=r_0N^{1/3}$ to examine the abnormal trend of the radius for neutron drip line nuclei. In view to guide the long tails, the density distribution for some skin candidates is analyzed. Finally, neutron skin thickness is observed for the whole considered isotopic series.

description: We present high resolution VLT UVES and low resolution FORS optical spectroscopy of supernova 2006aj and its host galaxy, associated with the nearby (z = 0.03342) gamma-ray burst GRB 060218. This host galaxy is a unique case, as it is one of the few nearby GRB host galaxies known, and it is only the second time high resolution spectra have been taken of a nearby GRB host galaxy (after GRB 980425). The resolution, wavelength range and S/N of the UVES spectrum combined with low resolution FORS spectra allow a detailed analysis of the circumburst and host galaxy environments. We analyse the emission and absorption lines in the spectrum, combining the high resolution UVES spectrum with low resolution FORS spectra and find the metallicity and chemical abundances in the host. We probe the geometry of the host by studying the emission line profiles. Our spectral analysis shows that the star forming region in the host is metal poor with 12 + log(O/H) = 7.54 (+0.17, -0.10) (~0.07 Z_sun), placing it among the most metal deficient subset of emission-line galaxies. It is also the lowest metallicity found so far for a GRB host from an emission-line analysis. Given the stellar mass of the galaxy of ~10^7 M_sun and the SFR (H alpha) = 0.065 +/- 0.005 M_sun/yr, the high specific star formation rate indicates an age for the galaxy of less than ~200 Myr. The brightest emission lines are clearly asymmetric and are well fit by two Gaussian components separated by ~22$ km/s. We detect two discrete Na I and Ca II absorption components at the same redshifts as the emission components. We tentatively interpret the two components as arising from two different starforming regions in the host, but high resolution imaging is necessary to confirm this.

description: The aim of the present thesis was to automatically recognize Adverse Drug Reactions (ADR) from free text snippets, by developing a system of web services which will extract semantic information from the respective free text (Services extracting semantic knowledge from text - SEST). We investigated the automatic ADR recognizing approaches, emphasizing on Apache UIMA (Unstructured Information Management Architecture). We defined our free text sources (Twitter and Pubmed), while designing the overall system’s architecture using software agents to collect the data and execute the overall procedure. We developed the software agents and the special UIMA components, executed the overall procedure for our collected dataset,comparing the automatically recognized ADRs with the ones already identified in the DrugBank. Finally, we presented our results, described our conclusions and defined some probable scenarios of future work.

Transgressing the technocratic culture of technology education: dominant and other stories of teacher, technology, curricula and teaching
Creators: name: Bastone, Christopher
Publisher: name: University of British Columbia
Year: 2009

description: This thesis is a study and transgression of the technocratic culture of technology education. The study problematizes technocratic ideology entrenched within the socialization of technology education teachers, common sense understandings of technology, technology education curricula, and industrial/technology education teaching practices. Knowledge is gained through life-history de/construction, socially critical examination of orthodox understandings of technology, technology education curricula, and classroom research in teaching social aspects of technology. Dominant and contrasting stories are revealed that describe and challenge the technocratic culture of technology education. The culture of technology education, from one teacher's perspective, is informed by the interpretative frames of industrial/technology educators, a technocratic consciousness within society, historical practices of industrial arts, and current political forces that shape technology education curricula. The author, as a classroom teacher, comes to a critical consciousness of personal and professional saturation in technocratic ideology. The story is told of the author's dislodgement from technocratic metanarratives and the growth of a heightened social consciousness of self, technology, curricula, and teaching. Such accounts infringe upon, or transgress, the near totalizing grip of technocratic consciousness within the culture of technology education. The study concludes that there is strong evidence of ingrained technocratic orientations within technology educators, common sense understanding of technology, curricular emphasis, and teaching practice and of the necessity to challenge such dominance. Possibilities are discussed for pedagogical practices that emphasize a critical, social, and cultural intelligence, rather than just a technical intelligence, in technology. While a technocratic culture for technology education may contribute to the goals of a technocracy, it is detrimental to the growth of an informed and critical democratic citizenry.
New predictions on meson decays from string splitting

description: We study certain exclusive decays of high spin mesons into mesons in models of large N_c Yang-Mills with few flavors at strong coupling using string theory. The rate of the process is calculated by studying the splitting of a macroscopic string on the relevant dual gravity backgrounds. In the leading channel for the decay of heavy quarkonium into two open-heavy quark states, one of the two produced mesons has much larger spin than the other. In this channel the decay rate is only power-like suppressed with the mass of the produced quark-anti quark pair. We also reconsider decays of high spin mesons made up of light quarks, confirming the linear dependence of the rate on the mass of the decaying meson. As a bonus of our computation, we provide a formula for the splitting rate of a macroscopic string lying on a Dp-brane in flat space.

description: Η παρούσα εργασία ερευνά τη σχέση μεταξύ δημόσιου χρέους και οικονομικής μεγέθυνσης και τους παράγοντες που επηρεάζουν αυτή τη σχέση για τις χώρες της ΕΕ27 κατά την περίοδο 1995-2011. Για τη μελέτη χρησιμοποιήθηκε το δημόσιο χρέος ως ποσοστό του ΑΕΠ και ο ρυθμός οικονομικής μεγέθυνσης των χωρών αυτών, κάνοντας χρήση της μεθοδολογίας System GMM. Τα αποτελέσματα της εμπειρικής έρευνας δείχνουν ότι γενικά υπάρχει αρνητική σχέση μεταξύ του δημόσιου χρέους και της οικονομικής μεγέθυνσης, ενώ παρέχουν ενδείξεις ύπαρξης αμφίδρομης σχέσης. Τόσο η εισαγωγή του Ευρώ ως ενιαίο νόμισμα και η κοινή νομισματική πολιτική, όσο και το ξέσπασμα της οικονομικής κρίσης το 2008, δεν άλλαξαν ουσιαστικά αυτή τη σχέση, είχαν ωστόσο συνολική αρνητική επίδραση στην αυτόνομη οικονομική μεγέθυνση των χωρών της ΕΕ27. Η μόνη περίπτωση όπου η ύπαρξη δημόσιου χρέους επιδρά θετικά στην οικονομική μεγέθυνση είναι όταν τα ποσοστά δημόσιου χρέους διατηρούνται μικρότερα του 60% του ΑΕΠ. Τέλος, τα επιτόκια δανεισμού επηρεάζουν αλλά δεν αλλάζουν την σχέση αυτή ενώ δεν έχει καμία επίδραση ο βαθμός της ανοιχτής οικονομίας ή παλιότερα επίπεδα δημόσιου χρέους.
description: The present thesis assesses the relationship between public debt and economic growth, as well as the factors that might affect this relationship for the European Union countries (EE27) during the period 1995-2011. It encompasses an empirical investigation using the public debt expressed as a percentage of GDP and the corresponding economic growth rate by applying the System-GMM methodology. The empirical results highlight the existence of a negative relationship between the public debt and the economic growth, while it provides evidence that this relationship might be bilateral. The relationship is present even regardless of the introduction of euro as a common currency and common monetary policy for the majority of the EE27 countries or the Economic Crisis that started in 2008. Additionally, those two events had an overall negative impact on the autonomous economic growth of the European Economies. However, the only time that the above negative relationship does not hold is for the case of the public debt as percentage of GDP is being less than 60%.
