description: Increasing competition present in the higher education in B&H has conditioned the trend that institutions need to “fight” for each student via quality development at higher education institutions. This paper deals with means of enhancing quality at eMPIRICA College through continual investigation of students’ satisfaction. For the purpose of this research, we used a quality questionnaire related to quality, satisfaction and loyalty of students. The research was carried out at the start and end of the academic year. This approach ascertained a gap with respect to quality, satisfaction and loyalty of students of eMPIRICA College. Using factor analysis the statements were grouped in 3 quality dimensions. The results of multivariate analysis of variance (MANOVA) showed that there is a significant statistical difference between expected and perceived quality, satisfaction and loyalty on the part of the students. Based on that, a gap between expectations and perceptions was ascertained. The use of t-test revealed that some statements have significant statistical difference in the area of expected and perceived quality, satisfaction and loyalty of students.

description: Given the current trends in the consulting countries of our region, as well as the degree of development of guidelines consulting with EU countries, the market for consultancy services in Serbia has not been significantly developed in the past. Owners and managers of companies are still not enough to feel the need for external services, which would solve business problems. Bearing in mind the level and quality of demand, not offer to consult services has not reached the required level. Accordingly aim at this paper is to examine the nature and developmental aspects of management consulting in Serbia in the transformation of the economy towards market business model. The research results show that the development of the market of consulting services is not a simple or easy task that can be accomplished in a short period and with modest financial contribution to the country. Local private consulting sector often lacks not only an interest in this area, but the real capacities, and entrepreneurs are willing to spend their time and money only to services from which they can see direct benefits in a very short period of time. In such circumstances, private market these service can hardly be generated independently.

description: We study the robustness of complex networks to multiple waves of simultaneous (i) targeted attacks in which the highest degree nodes are removed and (ii) random attacks (or failures) in which fractions $p_t$ and $p_r$ respectively of the nodes are removed until the network collapses. We find that the network design which optimizes network robustness has a bimodal degree distribution, with a fraction $r$ of the nodes having degree $k_2= (\kav - 1 +r)/r$ and the remainder of the nodes having degree $k_1=1$, where $\kav$ is the average degree of all the nodes. We find that the optimal value of $r$ is of the order of $p_t/p_r$ for $p_t/p_r\ll 1$.

description: The status of lattice QCD investigations at high temperature is reviewed. After a short introduction into thermal QCD on the lattice we report on the present understanding of the phase diagram and the equation of state, in particular in presence of dynamical quarks. We continue with a discussion of various screening lengths in the plasma phase including results from dimensionally reduced QCD. This is followed by summarizing lattice data on quark number susceptibilities and spectral densities, both of which are of immediate relevance to the interpretation of heavy ion experiments. A major section is devoted to presenting simulations of QCD at small yet phenomenologically important values for the baryon density.

Variational approach for the two-dimensional trapped Bose Einstein condensate

Publisher: name: arXiv
Year: 2003
Subjects: subject: Other Condensed Matter (cond-mat.other)
subject: FOS: Physical sciences

description: We construct a many-body Gaussian variational approach for the two-dimensional trapped Bose gas in the condensate phase. Interaction between particles is modelized by a generalized pseudo-potential of zero range that allows recovering perturbative results in the ultra-dilute limit, while back action of non-condensate particles on the condensate part is taken into account for higher density. As an application, we derive the equation of state and solve stability problems encountered in similar mean-field formalisms for a single vortex configuration.

description: Several methods for preparing well equilibrated melts of long chains polymers are studied. We show that the standard method in which one starts with an ensemble of chains with the correct end-to-end distance arranged randomly in the simulation cell and introduces the excluded volume rapidly, leads to deformation on short length scales. This deformation is strongest for long chains and relaxes only after the chains have moved their own size. Two methods are shown to overcome this local deformation of the chains. One method is to first pre-pack the Gaussian chains, which reduces the density fluctuations in the system, followed by a gradual introduction of the excluded volume. The second method is a double-pivot algorithm in which new bonds are formed across a pair of chains, creating two new chains each substantially different from the original. We demonstrate the effectiveness of these methods for a linear bead spring polymer model with both zero and nonzero bending stiffness, however the methods are applicable to more complex architectures such as branched and star polymer.

description: In this study, superhydrophobic surfaces were fabricated using 1H,1H,2H,2H-perfluorooctyltriethoxysilane monolayer deposition on thermally oxidized brass. The superhydrophobic surface showed a contact angle (CA) of 155° with a CA hysteresis of 3.5°. The corrosion behaviour of developed superhydrophobic surface was evaluated using potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) studies in 3.5% NaCl solution. The superhydrophobic surface showed exceptional corrosion behaviour with nearly 21 times higher corrosion resistance compared to as-received (AS) brass. The EIS analysis suggests the presence of Warburg impedance in the AS brass indicating diffusion phenomena, while superhydrophobic brass surface showed a reversed loop in the low-frequency spectra, signifying significantly delayed kinetics of the electrochemical system. The study provides a facile, promising means of developing highly corrosion-resistant surfaces in engineering materials.

description: We show that the commonly known conductor boundary conditions $E_{||}=B_\perp=0$ can be realized in two ways which we call 'thick' and 'thin' conductor. The 'thick' conductor is the commonly known approach and includes a Neumann condition on the normal component $E_\perp$ of the electric field whereas for a 'thin' conductor $E_\perp$ remains without boundary condition. Both types describe different physics already on the classical level where a 'thin' conductor allows for an interaction between the normal components of currents on both sides. On quantum level different forces between a conductor and a single electron or a neutral atom result. For instance, the Casimir-Polder force for a 'thin' conductor is by about 13% smaller than for a 'thick' one.

description: 12. Baccharis bicolor (Joch. Müll.) G. Heiden, comb. et stat. nov.
 Basionym: Baccharis coridifolia subsp. bicolor Müller (2006: 276). — Type: BOLIVIA. Cochabamba: Prov. Ayopaya, Independencia 22 km hacia Kami, em dirección S, 3670 m, 29 November 1981, ♂ & ♀, S . Beck 7467 (holotype JE (00005245) photo!; isotypes G, LPB, SI! (004229), US! (00901686), USZ).
 Müller (2006) applied the infraspecific rank of subspecies to “taxa that are morphologically (nearly) always well separated and have distinct or scarcely overlapping distributions” and used varieties for “taxa in which the character states show frequent overlap and which are sympatric”. In the current checklist, any taxon that can be distinguished from the others by morphological characters is considered a species and therefore a new combination and status is proposed. As pointed out by Müller (2006), B. bicolor can be distinguished from B. coridifolia by, amongst others, leaves and shoots with a persistent indumentum of filiform hairs and a pappus of female florets with less than 60 bristles. In contrast, B. coridifolia has longer and wider leaves and shoots without filiform hairs or with these only present on very young structures and then caduceus. Baccharis coridifolia has female florets with a pappus of more than 80 bristles. Both species do not overlap in geographic distribution, since B. bicolor is restricted to the Yungas of northeastern Bolivia (elevations between 2500-3500 m in the Departments of Cochabamba and La Paz) while B. coridifolia is widespread in southern South America, occurring from southwestern Bolivia (elevations between 1200-2700 m in the Departments of Chuquisaca, Tarija and Santa Cruz) to southeastern Brazil, south to central and eastern Argentina.

This provides a significantly reduced upper limit on the mass of the lightest supersymmetric particle LSP: m_χ< 500 GeV for \tan β< 45 and μ> 0, or \tan β< 30 and μ< 0, thereby improving the prospects for measuring supersymmetry at the LHC, and increasing the likelihood that a 1-TeV linear e^+ e^- collider would be able to measure the properties of some supersymmetric particles.

description: The structural, electronic, and spectroscopic properties of a high-pressure phase of methane hydrate (MH-III) are studied by first principles electronic structure calculations. A detailed analysis of the atomic positions suggests that {\it ionization} of hydrogen-bonded water molecules occurs around 40GPa and {\it centering} or symmetrization of hydrogen-bonds occurs around 70 GPa. These pressures are much lower compared with ioninzation around 55 GPa and centering around 100 GPa in pure ice. The transition may be observed with low-temperature IR/Raman spectroscopy of OH stretching modes or neutron diffraction.

description: Rapid changes in climatic conditions threaten both socioeconomic and ecological systems, as these might not be able to adapt or to migrate at the same pace as that of global warming. In particular, an increase of weather and climate extremes can lead to increased stress on human and natural systems, and a tendency for serious adverse effects. We rely on the EURO-CORDEX simulations and focus on the the screen-level daily mean temperature (T2m). We compare the shifting velocities of the cold and hot extremes with these of the associated central trends, i.e., the arithmetical mean or median. We define the extremes relative to the T2m distribution as it evolves with time over the period of 1951--2100. We find that temperature extremes shift at a similar velocity compared to that of the central trends. Accordingly, the T2m probability distribution shifts mostly as a whole, as the tails of the distribution increase together with the central trends. Exceptions occur however in specific regions and for the clustering of warm days, which shifts slower than all other extremes investigated in this study.

CSV-LD: Spreadsheet-based Linked Data

Publisher: name: Zenodo
Year: 2021

description: Comma-separated-values (CSV) is a useful data serialization and sharing format. This talk introduces the idea of CSV-LD as a CSV-based format to serialize Linked Data, mirroring the way that JSON-LD is a JSON-based format to serialize Linked Data. "CSV" here includes any dialect that uses a different delimiter, such as tab-separated-values (TSV). The syntax of CSV-LD is designed to easily integrate into workflows that already use CSV, and provides a smooth upgrade path from CSV to CSV-LD. It is primarily intended to be a way to use Linked Data as part of spreadsheet-based data entry; to facilitate data validation, display, and conversion of CSV into other formats via use of CSV on the Web (CSVW) metadata; and to build FAIR data services. The term "CSV-LD" was previously used to describe a now-obsoleted precursor to the CSVW specifications; both approaches require a second file, a JSON-LD template document, to be shared along with a CSV file. The approach described here, in contrast, requires only a CSV file from the data producer, one that includes links to CSVW-powered metadata.

description: Background: Coronavirus disease 2019 (COVID-19) has rapidly spread worldwide, but safe and effective treatment options remain unavailable. Numerous systematic reviews of varying qualities have tried to summarize the evidence on the available therapeutic interventions for COVID-19. This overview of reviews aims to provide a succinct summary of the findings of systematic reviews on different pharmacological and non-pharmacological therapeutic interventions for COVID-19. Methods: We searched PubMed, Embase, Google Scholar, Cochrane Database of Systematic Reviews, and WHO database of publications on COVID-19 from 1 December 2019 through to 11 June 2020 for peer-reviewed systematic review studies that reported on potential pharmacological or non-pharmacological therapies for COVID-19. Quality assessment was completed using A MeaSurement Tool to Assess systematic Reviews-2 (AMSTAR-2) measure. Results: Out of 816 non-duplicate studies, 45 were included in the overview. Antiviral and antibiotic agents, corticosteroids, and anti-malarial agents were the most common drug classes used to treat COVID-19; however, there was no direct or strong evidence to support their efficacy. Oxygen therapy and ventilatory support was the most common non-pharmacological supportive care. The quality of most of the included reviews was rated as low or critically low. Conclusion: This overview of reviews demonstrates that although some therapeutic interventions may be beneficial to specific subgroups of COVID-19 patients, the available data are insufficient to strongly recommend any particular treatment option to be used at a population level. Future systematic reviews on COVID-19 treatments should adhere to the recommended systematic review methodologies and ensure that promptness and comprehensiveness are balanced.

A reasonable agreement with the experimental data for shadowing is obtained in a scenario of downward spectral shift of the hadrons. We show that distinguishable features for in-medium changes of the hadronic properties can be observed experimentally through the dilepton spectrum by judicious choice of target nuclei and incident energy of photons.

description: This paper reports on the X-past project carried out by the Netherlands Historical Data Archive (NHDA). The main goal of the project is to investigate how the XML data format can improve the durability and access of historical datasets. The assumptions upon which XML is considered as durable are covered. The formatting of datasets in XML format is described. The X-past project investigated the possibilities to provide access to historical datasets by means of the ¹ÄúOpen Archives Initiative ¹ÄìProtocol for Metadata Harvesting¹Äù (OIA-PMH). This protocol uses the XML data format to express the syntax of verbs. Within the framework of the X-past project a prototype information system is developed as a proof of concept, based on which further system requirements have been defined. This paper will present the results of the X-past project and also look forward to its follow-up, Xara.

description: We give a geometrical characterization of $λ$-prolongations of vector fields, and hence of $λ$-symmetries of ODEs. This allows an extension to the case of PDEs and systems of PDEs; in this context the central object is a horizontal one-form $μ$, and we speak of $μ$-prolongations of vector fields and $μ$-symmetries of PDEs. We show that these are as good as standard symmetries in providing symmetry reduction of PDEs and systems, and explicit invariant solutions.

description: We study chargino pair production on the heavy Higgs resonances at a muon collider in the MSSM. At $\sqrt{s} \approx 350$ GeV cross sections up to 2 pb are reached depending on the supersymmetric scenario and the beam energy spread. The resonances of the scalar and pseudoscalar Higgs bosons may be separated for $\tanβ<8$. Our aim is to determine the ratio of the chargino couplings to the heavy scalar and pseudoscalar Higgs boson independently of the specific chargino decay characteristics. The precision of the measurement depends on the energy resolution of the muon collider and on the error in the measurement of the cross sections of the non-Higgs channels including an irreducible standard model background. With a high energy resolution the systematic error can be reduced to the order of a few percent.

description: When Anderson localization takes place in a quenched disordered system, a continuous symmetry can be broken spontaneously without accompanying Goldstone bosons. Elaborating on this observation we propose a unified, microscopic physical picture of the phase diagram of both quenched and unquenched QCD with two flavors of Wilson fermions. The phase with Goldstone bosons -- by definition the Aoki phase -- is always identified as the region where the mobility edge of the (hermitian) Wilson operator is zero. We then discuss the implications for domain-wall and overlap fermions. We conclude that both formulations are valid only well outside the Aoki phase of the associated Wilson-operator kernel, because this is where locality and chirality can be both maintained.

description: The GUSBAD catalog of gamma-ray bursts (GRBs) is based on archival BATSE DISCLA data covering the full 9.1 years of the Compton Gamma Ray Observatory mission. The catalog contains 2204 GRBs, including 589 bursts not listed in the Current BATSE Burst Catalog. The GUSBAD catalog is uniform in the sense that the detection criteria are the same throughout and that the properties given in the catalog are available for every burst. The detection and the derivation of the properties of the GRBs were carried out automatically. This makes the GUSBAD catalog especially suitable for statistical work and simulations, such as used in the derivation of V/Vmax. We briefly touch upon a potential problem in defining a GRB duration that is physically meaningful.

description: The standard cosmological paradigm narrates a reassuring story of a universe currently dominated by an enigmatic dark energy component. Disquietingly, its universal explaining power has recently been challenged by, above all, the $\sim4σ$ tension in the values of the Hubble constant. Another, less studied anomaly is the repeated observation of integrated Sachs-Wolfe imprints $\sim5\times$ stronger than expected in the $Λ$CDM model from R>100 $Mpc/h$ super-structures. Here we show that the inhomogeneous AvERA model of emerging curvature is capable of telling a plausible albeit radically different story that explains both observational anomalies without dark energy. We demonstrate that while stacked imprints of R>100 $Mpc/h$ supervoids in cosmic microwave background temperature maps can discriminate between the AvERA and $Λ$CDM models, their characteristic differences may remain hidden using alternative void definitions and stacking methodologies. Testing the extremes, we then also show that the CMB Cold Spot can plausibly be explained in the AvERA model as an ISW imprint. The coldest spot in the AvERA map is aligned with multiple low-$z$ supervoids with R>100 $Mpc/h$ and central underdensity $δ_{0}\approx-0.3$, resembling the observed large-scale galaxy density field in the Cold Spot area. We hence conclude that the anomalous imprint of supervoids may well be the canary in the coal mine, and existing observational evidence for dark energy should be re-interpreted to further test alternative models.

description: Many-body dissipative particle dynamics is constructed to exhibit vapour-liquid coexistence, with a sharp interface, and a vapour phase of vanishingly small density. In this form, the model is an unusual example of a soft-sphere liquid with a potential energy built out of local-density dependent one-particle self energies. The application to fluid mechanics problems involving free surfaces is illustrated by simulation of a pendant drop.

description: Quantum many body system in equilibrium can be effectively characterized using the framework of quantum statistical mechanics. However, nonequilibrium behaviour of quantum many body systems remains elusive, out of the range of such a well established framework. Experiments in quantum simulators are now opening up a route towards the generation of quantum states beyond this equilibrium paradigm. As an example in closed quantum many body systems, dynamical quantum phase transitions behave as phase transitions in time with physical quantities becoming nonanalytic at critical times, extending important principles such as universality to the nonequilibrium realm. Here, in solid state quantum simulator we develop and experimentally demonstrate that out-of-time-order correlators, a central concept to quantify quantum information scrambling and quantum chaos, can be used to dynamically detect nonoequilibrium phase transitions in the transverse field Ising model. We also study the multiple quantum spectra, eventually observe the buildup of quantum correlation. Further applications of this protocol could enable studies other of exotic phenomena such as many body localization, and tests of the holographic duality between quantum and gravitational systems.

description: Experiments with bosonic atoms in optical superlattices allow for the interesting possibility to study the adiabatic quantized pumping of bosonic atoms in the presence of interactions. We investigate this exotic phenomenon for bound bosonic pairs in the paradigmatic Su-Schrieffer-Heeger model where the ground state exhibits topological phase transitions due to dimerized hoppings. At unit filling we show that there exist crossovers and phase transitions to bond-order phases of paired bosons known as pair-bond-order phase as a function of attractive interactions. The pair bond order phase is found to exhibit effective topological properties such as the presence of polarized paired edge states. This is further analyzed by studying the emergence and breakdown of the Thouless charge pumping of this bound bosonic pairs by a parametric extension to the famous Rice-Mele model. Finally we discuss how the pumping of paired bosons or different regimes of breakdown of charge pumping can be probed by state-of-the art experiments with repulsively bound bosons.

description: The measured correlations of financial time series in subsequent epochs change considerably as a function of time. When studying the whole correlation matrices, quasi-stationary patterns, referred to as market states, are seen by applying clustering methods. They emerge, disappear or reemerge, but they are dominated by the collective motion of all stocks. In the jargon, one speaks of the market motion, it is always associated with the largest eigenvalue of the correlation matrices. Thus the question arises, if one can extract more refined information on the system by subtracting the dominating market motion in a proper way. To this end we introduce a new approach by clustering reduced-rank correlation matrices which are obtained by subtracting the dyadic matrix belonging to the largest eigenvalue from the standard correlation matrices. We analyze daily data of 262 companies of the S&P 500 index over a period of almost 15 years from 2002 to 2016. The resulting dynamics is remarkably different, and the corresponding market states are quasi-stationary over a long period of time. Our approach adds to the attempts to separate endogenous from exogenous effects.

description: A Canadian Research Data Centre pilot project was conducted to evaluate the use of the Data Documentation Initiative (DDI) standard with the confidential data file of the Canadian General Social Survey, Cycle 17. Among the objectives of this study was to assess how well DDI captured the life cycle of the creation and management of metadata within a major survey, including the initial planning stages all the way through to official announcements of products. This study sought to identify the variety of metadata tools used by Cycle 17's author division within Statistics Canada and to map the relationship between these documentation systems and the elements in the DDI standard. This paper reports on the findings of this pilot project.

description: Modelling movement uncertainty is of profound significance in promoting effective trajectory analysis and mining. However, classic uncertainty models are limited by rigid assumptions on moving speed and distance, which ignores the stochastic nature of individual’s travel behaviour. This study introduces a novel method using adaptive ellipses to represent the movement uncertainty in a planar space under the framework of time geography. Two models are established by considering different error sources in trajectory data. The first model captures the uncertainty caused by sampling error, and the second one further, takes the measurement error into account. The Minkowski distance metric is adopted to determine the size of uncertainty ellipses, in which the Minkowski parameter is optimized for each segment in the raw trajectory on the basis of the geometric characteristics extracted. Compared with state-of-the-art methods on five real-life trajectory datasets, the proposed method is proved to produce more effective uncertain regions, which significantly reduce the redundant uncertain area, while retaining at a comparative level of actual movement coverage. Given the heterogeneity of human mobility patterns, this study provides a robust and applicable solution for adaptively modelling individual’s movement uncertainty, which is expected to benefit trajectory-related applications in various scenarios.

description: This report updates the Canned Fruit and Vegetable Consumption in the United States: Report to the United States Congress (September 2008), using more recent data through 2008, where available. Both reports were prepared and published in response to requests from Congress. We used data from the Economic Research Service’s Food Availability Data System, Bureau of Labor Statistics’ Consumer Expenditure Surveys, and the U.S. Department of Agriculture’s food intake surveys to study U.S. consumption of and spending on canned fruits and vegetables. Data since 1970 suggest that the share of canned fruit out of total fruit consumed will continue to be fairly constant at around 6 percent in the short term, while the share of canned vegetables out of total vegetables consumed will continue to fl uctuate—but mostly decline—from the 24 percent share in 2008. The analysis tracks the changes in canned fruit and vegetable expenditures since the previous report, and breaks down these expenditures by demographic characteristics of households, including age and ethnicity.
Surgery in the Western Canadian Arctic : Using a logic model to understand and strengthen a rural surgical system
Creators: name: Falk, Ryan
Publisher: name: The University of British Columbia
Year: 2022

description: Introduction: Rural, remote, indigenous, and circumpolar populations have worse health outcomes when compared with their urban counterparts. Little is known about the surgical needs of such populations, and the delivery of surgical services to such geographically isolated regions poses many challenges. The networked model of care integrating family physicians with enhanced surgical skills (FPESS) and specialist surgeons (SS) provides a sustainable solution to these challenges. This project studied the system of surgical care delivery for the population living in one circumpolar region of the western Canadian Arctic, the Beaufort Delta. Methods: Using a participatory approach, a logic model was developed to describe the delivery of surgical services to the Beaufort Delta Region. Semi-structured interviews were conducted with relevant stakeholders working within the Northwest Territories Health & Social Services Authority in an iterative process following grounded theory. Quantitative methods were also proposed to contribute to an understanding of the surgical needs of the population, as well as the relative impact of each type of surgical care provider in the overall care for the region, but these data remain unavailable at the time of writing. Results: The logic model is presented in graphic and narrative form, detailing the roles of providers involved in surgical care, from community health nurses (CHNs) to sub-specialist surgeons at the tertiary care centres of Edmonton, Alberta. The focus, however, is on the role and interactions between FPESS and SS in the surgical care provided to the region in the demonstration of this networked model of care. Recommendations to improve the host surgical system, based on the interviews with stakeholders and on the literature review, are made. Discussion: This study provides insight into a functioning example of a networked model of surgical care. FPESS and SS work together to improve access to surgical care for this disadvantaged population. Although there is room for improvement, the BDR model demonstrates many of the qualities of networked care as described in the literature. Further study into this model can contribute to a better understanding of circumpolar surgical needs and care delivery, which is a current gap in knowledge, and may benefit other global regions facing similar challenges in the delivery of surgical care. Recommendations from this project can also serve as a platform for knowledge translation to the host surgical system.

description: The class of layered 3D-topological insulators have shown intriguingly anomalous temperature dependence in their thermal expansion coefficients. It was proposed that stacking faults are the origin of the observed anomalous thermal expansion. Here, using femtosecond pump-probe differential reflectivity measurements we probe the carrier and coherently generated totally symmetric A1g1 optical phonons in Bi2Se3. Transient signals also show a low frequency (~GHz) oscillations due to coherent longitudinal acoustic phonons. We extract temperature dependence of optical constants, sound velocity and Young's modulus of Bi2Se3 using the strain pulse propagation model. A remarkable anomalous behavior around ~180 K is observed in the temperature dependence of optical and acoustic phonons as well as the optical constants. First-principles density functional theory (DFT) reveals that thermally activated formation of stacking faults is responsible for the anomalies observed in Bi2Se3, similar to case of Sb2Te3. We also show that inclusion of spin-orbit coupling plays an important role in reducing the total energy difference between the pristine and the faulted structures.
