description: The present study offers a comparative analysis with exploration approach among university library websites in Iran and United States from standpoint user engagement via social medias. Descriptive survey method was used in this study. Websites composed of 21 academic university library websites in Iran and 16 academic university library websites in United states (37 websites) were investigated by direct observation using analytical database “similarweb“ during 3 months (February up to April 2019). Findings showed that in United States, 100% of the total university library websites attracted users through social media, compared to 19% in Iran. The number of users clicking or visiting the website of the university library via social media in Iran was 3% of the total number of users visiting the library's website. This figure in United States was up to 1% (Except for the MIT University libraries that the number was 11%). Facebook, YouTube, Twitter, Reddit, Researchgate and Pinterest were the top media that university library websites in United States had user engagement through them.

description: This is the second and final article on the tutorial on manipulator differential kinematics. In Part 1, we described a method of modelling kinematics using the elementary transform sequence (ETS), before formulating forward kinematics and the manipulator Jacobian. We then described some basic applications of the manipulator Jacobian including resolved-rate motion control (RRMC), inverse kinematics (IK), and some manipulator performance measures. In this article, we formulate the second-order differential kinematics, leading to a definition of manipulator Hessian. We then describe the differential kinematics' analytical forms, which are essential to dynamics applications. Subsequently, we provide a general formula for higher-order derivatives. The first application we consider is advanced velocity control. In this section, we extend resolved-rate motion control to perform sub-tasks while still achieving the goal before redefining the algorithm as a quadratic program to enable greater flexibility and additional constraints. We then take another look at numerical inverse kinematics with an emphasis on adding constraints. Finally, we analyse how the manipulator Hessian can help to escape singularities. We have provided Jupyter Notebooks to accompany each section within this tutorial. The Notebooks are written in Python code and use the Robotics Toolbox for Python, and the Swift Simulator to provide examples and implementations of algorithms. While not absolutely essential, for the most engaging and informative experience, we recommend working through the Jupyter Notebooks while reading this article. The Notebooks and setup instructions can be accessed at https://github.com/jhavl/dkt.

description: The present study proposed and test a model that connects both affective and cognitive factors in cellular service to customers’ recommendation behavior. Results of the analysis of data collected through questionnaire from 293 respondents with cellular phones and active account in the Nigerian cellular industry indicate that core cellular service dimensions, service cost (price) and hedonic values are significant determinants of customers’ recommendation behavior. In addition, the study found that customer service and utilitarian value exert negative effect on recommendation behavior. It seems that strengthening the performance of service providers on core service attributes, service cost (price) and the entertainment and emotion evoking aspects of cellular service is of more value in partnering with customer to enlarge customer base through recommendation.

description: Suzaku observed the region including HESS J1809-193, one of the TeV unidentified (unID) sources, and confirmed existence of the extended hard X-ray emission previously reported by ASCA, as well as hard X-ray emission from the pulsar PSR J1809-1917 in the region. One-dimensional profile of the diffuse emission is represented with a Gaussian model with the best-fit sigma of 7+-1 arcmin. The diffuse emission extends for at least 21 pc (at the 3sigma level, assuming the distance of 3.5 kpc), and has a hard spectrum with the photon index of Gamma ~1.7. The hard spectrum suggests the pulsar wind nebula (PWN) origin, which is also strengthened by the hard X-ray emission from PSR J1809-1917 itself. Thanks to the low background of Suzaku XIS, we were able to investigate spatial variation of the energy spectrum, but no systematic spectral change in the extended emission is found. These results imply that the X-ray emitting pulsar wind electrons can travel up to 21 pc from the pulsar without noticeable energy loss via synchrotron emission.

Lying for the Greater Good: Bounded Rationality in a Team
Creators: name: Sürücü, Oktay
Publisher: name: International Journal of Economic Behavior
Year: 2014

description: This paper is concerned with the interaction between fully and boundedly rational agents in situations where their interests are perfectly aligned. The cognitive limitations of the boundedly rational agent do not allow him to fully understand the market conditions and lead him to take non-optimal decisions in some situations. Using categorization to model bounded rationality, we show that the fully rational agent can nudge, i.e., he can manipulate the information he sends and decrease the expected loss caused by the boundedly rational agent. Assuming different types for the boundedly rational agent, who differ only in the categories used, we show that the fully rational agent may learn the type of the boundedly rational agent along their interaction. Using this additional information, the outcome can be improved and the amount of manipulated information can be decreased. Furthermore, as the length of the interaction increases the probability that the fully rational agent learns the type of the boundedly rational agent grows.

description: Since 1970s several authors (Benton, 1976 ; Dymsza, 1984 ) stressed the need for adopting an interdisciplinary approach. According to Brewer (1999) “interdisciplinarity generally refers to the appropriate combination of knowledge from many different specialities - especially as a means to shed new light on an actual problem”. Nissani (1997) identified ten advantages of adopting interdisciplinarity knowledge and research, and one of the most important is that several intellectual, social, and practical problems need interdisciplinary approaches. Finally, during the last decade, the vast majority of call for papers, textbooks and research initiatives required or offered and interdisciplinary approach (Knights and Willmott, 1997) . The International Journal of Economic Behavior is multidisciplinary in nature and the papers collected in this issue contribute in enhancing the adoption of interdisciplinarity, especially providing stimuli for future research of economic behavior and management perspectives.

description: Manipulator kinematics is concerned with the motion of each link within a manipulator without considering mass or force. In this article, which is the first in a two-part tutorial, we provide an introduction to modelling manipulator kinematics using the elementary transform sequence (ETS). Then we formulate the first-order differential kinematics, which leads to the manipulator Jacobian, which is the basis for velocity control and inverse kinematics. We describe essential classical techniques which rely on the manipulator Jacobian before exhibiting some contemporary applications. Part II of this tutorial provides a formulation of second and higher-order differential kinematics, introduces the manipulator Hessian, and illustrates advanced techniques, some of which improve the performance of techniques demonstrated in Part I. We have provided Jupyter Notebooks to accompany each section within this tutorial. The Notebooks are written in Python code and use the Robotics Toolbox for Python, and the Swift Simulator to provide examples and implementations of algorithms.

description: We develop an approach aimed at optimizing the parameters of a network of biochemical logic gates for reduction of the "analog" noise buildup. Experiments for three coupled enzymatic AND gates are reported, illustrating our procedure. Specifically, starch - one of the controlled network inputs - is converted to maltose by beta-amylase. With the use of phosphate (another controlled input), maltose phosphorylase then produces glucose. Finally, nicotinamide adenine dinucleotide (NAD+) - the third controlled input - is reduced under the action of glucose dehydrogenase to yield the optically detected signal. Network functioning is analyzed by varying selective inputs and fitting standardized few-parameters "response-surface" functions assumed for each gate. This allows a certain probe of the individual gate quality, but primarily yields information on the relative contribution of the gates to noise amplification. The derived information is then used to modify our experimental system to put it in a regime of a less noisy operation.

May the Soul of The IFS Financial System Definition RIP in Developing Countries
Creators: name: Asongu, Simplice A.
Publisher: name: International Journal of Economic Behavior
Year: 2015

description: In this paper, we dissect with great acuteness contemporary insufficiencies of the IFS (2008) definition of the financial system and conclude from sound theoretical underpinnings and empirical justifications that the foundation, on which it is based, while solid for developed countries, holds less ground in developing countries. Perhaps one of the deepest empirical hollows in the financial development literature has been the equation of financial depth in the perspective of money supply to liquid liabilities. This equation has put on the margin (and skewed) burgeoning phenomena of mobile banking, knowledge economy (KE), inequality…etc. We conclude that the informal financial sector, a previously missing component in the IFS conception and definition of the financial system can only be marginalized at the cost of misunderstanding recent burgeoning trends in mobile phone penetration, KE and poverty. Hence, the IFS definition has incontrovertibly fought its final dead battle and lost in the face of soaring trends highlighted above. Despite the plethora of econometric and policy-making sins the definition has committed in developing countries through bias estimates and misleading inferences, may its soul RIP.

description: We calculate the CP-averaged branching ratios and CP-violating asymmetries for the two-body charmless hadronic decays $Λ_b \to p π, pK$ in the perturbative QCD (pQCD) approach to lowest order in $α_s$. The baryon distribution amplitudes involved in the factorization formulae are considered to the leading twist accuracy and the distribution amplitudes of the proton are expanded to the next-to-leading conformal spin (i.e., "P" -waves), the moments of which are determined from QCD sum rules. Our work shows that the contributions from the factorizable diagrams in $Λ_b \to p π, pK$ decays are much smaller compared to the non-factorizable diagrams in the conventional pQCD approach. We argue that this reflects the estimates of the $Λ_b \to p$ transition form factors in the $k_T$ factorization approach, which are found typically an order of magnitude smaller than those estimated in the light-cone sum rules and in the non-relativistic quark model. As an alternative, we adopt a hybrid pQCD approach, in which we compute the factorizable contributions with the $Λ_b \to p$ form factors taken from the light cone QCD sum rules. The non-factorizable diagrams are evaluated utilizing the conventional pQCD formalism which is free from the endpoint singularities. The predictions worked out here are confronted with the recently available data from the CDF collaboration on the branching ratios and the direct CP asymmetries for the decays $ Λ_b \to p π$, and $Λ_b \to p K$. The asymmetry parameter $α$ relevant for the anisotropic angular distribution of the emitted proton in the polarized $Λ_b$ baryon decays is also calculated for the two decay modes.

description: Balance and gait disorders are the second leading cause of falls, which, along with consequent injuries, are reported as major public health problems all over the world. For patients who do not require mechanical support, vibrotactile feedback interfaces have proven to be a successful approach in restoring balance. Most of the existing strategies assess trunk or head tilt and velocity or plantar forces, and are limited to the analysis of stance. On the other hand, central to balance control is the need to maintain the body's centre of pressure (CoP) within feasible limits of the support polygon (SP), as in standing, or on track to a new SP, as in walking. Hence, this paper proposes an exploratory study to investigate whether vibrotactile feedback can be employed to lead human CoP during walking. The ErgoTac-Belt vibrotactile device is introduced to instruct the users about the direction to take, both in the antero-posterior and medio-lateral axes. An anticipatory strategy is adopted here, to give the users enough time to react to the stimuli. Experiments on ten healthy subjects demonstrated the promising capability of the proposed device to guide the users' CoP along a predefined reference path, with similar performance as the one achieved with visual feedback. Future developments will investigate our strategy and device in guiding the CoP of elderly or individuals with vestibular impairments, who may not be aware of or, able to figure out, a safe and ergonomic CoP path.

description: Angle-resolved photoemission measurements were performed on Zn-doped La2-xSrxCuO4 (LSCO) to investigate the effects of Zn impurities on the low energy electronic structure. The Zn-impurity-induced increase in the quasi-particle (QP) width in momentum distribution curves (MDC) is approximately isotropic on the entire Fermi surface and energy-independent near the Fermi level (EF). The increase in the MDC width is consistent with the increase in the residual resistivity due to the Zn impurities if we assume the carrier number to be 1-x for x=0.17 and the Zn impurity to be a potential scatterer close to the unitarity limit. For x=0.03, the residual resistivity is found to be higher than that expected from the MDC width, and the effects of antifferomagnetic fluctuations induced around the Zn impurities are discussed. The leading edges of the spectra near (pi,0) for x=0.17 are shifted toward higher energies relative to EF with Zn substitution, indicating a reduction of the superconducting gap.

description: This paper investigates the properties of spin-1/2 particle Zitterbewegung in the presence of a general curved space-time background described in terms of Fermi normal co-ordinates, where the spatial part is expressed using general curvilinear co-ordinates. Adopting the approach first introduced by Barut and Bracken for Zitterbewegung in the local rest frame of the particle, it is shown that non-trivial gravitational contributions to the relative position and momentum operators appear due to the coupling of Zitterbewegung frequency terms with the Ricci curvature tensor in the Fermi frame, indicating a formal violation of the weak equivalence principle. Explicit expressions for these contributions are shown for the case of quasi-circular orbital motion of a spin-1/2 particle in a Vaidya background. Formal expressions also appear for the time-derivative of the Pauli-Lubanski vector due to space-time curvature effects coupled to the Zitterbewegung frequency. As well, the choice of curvilinear co-ordinates results in non-inertial contributions in the time evolution of the canonical momentum for the spin-1/2 particle, where Zitterbewegung effects lead to stability considerations for its propagation, based on the Floquet theory of differential equations.

description: Radial-velocity measurements and sine-curve fits to the orbital radial velocity variations are presented for the last eight close binary systems analyzed the same way as in the previous papers of this series: QX And, DY Cet, MR Del, HI Dra, DD Mon, V868 Mon, ER Ori, and Y Sex. For another seven systems (TT Cet, AA Cet, CW Lyn, V563 Lyr, CW Sge, LV Vir and MW Vir) phase coverage is insufficient to provide reliable orbits but radial velocities of individual components were measured. Observations of a few complicated systems observed throughout the DDO close-binary program are also presented; among them an especially interesting is the multiple system V857 Her which - in addition to the contact binary - very probably contains one or more sub-dwarf components of much earlier spectral type. All suspected binaries which were found to be most probably pulsating stars are briefly discussed in terms of mean radial velocities and projected rotation velocities (v sin i) as well as spectral type estimates. In two of them, CU CVn and V752 Mon, the broadening functions show a clear presence of non-radial pulsations. The previously missing spectral types for the DDO I paper are given here in addition to such estimates for most of the program stars of this paper.

description: Ba$_3$CoSb$_2$O$_9$ approximates the two-dimensional spin-1/2 triangular-lattice Heisenberg antiferromagnet. This compound displays magnetic-field-induced quantum phase transitions, including the 1/3-magnetization-plateau, but its magnetization processes for the magnetic field $H$ parallel and perpendicular to the $c$ axis are different due to the weak easy-plane anisotropy and the weak interlayer antiferromagnetic exchange interaction. To elucidate how the quantum phase transitions change between these two field directions, we measured the field-angle dependence of the magnetization process in Ba$_3$CoSb$_2$O$_9$ using pulsed high magnetic fields. We compared obtained magnetic field-field angle phase diagram with those obtained by the large-size cluster mean-field method combined with a scaling scheme and the semiclassical theory. We also found a narrow 1/3-magnetization plateau and a high-field transition with a small magnetization jump for $H\,{\parallel}\,c$, not observed in the previous studies.

description: A popular intermediary in the theory of artificial satellites is obtained after the elimination of parallactic terms from the J2-problem Hamiltonian. The resulting quasi-Keplerian system is in turn converted into the Kepler problem by a torsion. When this reduction process is applied to unbounded orbits the solution is made of Keplerian hyperbolae. For this last case, we show that the torsion-based solution provides an effective alternative to the Keplerian approximation customarily used in flyby computations. Also, we check that the extension of the torsion-based solution to higher orders of the oblateness coefficient yields the expected convergence of asymptotic solutions to the true orbit.

description: Recent developments in spintronics have drawn renewed attention to the spin dynamics of cubic ferromagnetic crystals EuO and EuS. These ferromagnets have the simplest possible magnetic structure, making them the most suitable systems for testing various theoretical models of magnetic materials. A commonly used Weiss mean-field approximation (MFA) provides only a qualitative description of the magnetization temperature dependence $M(T)$. We develop a consistent theory for $M(T)$ based on the perturbation diagrammatic technique for spin operators. Our theory is in excellent quantitative agreement with the experimental dependence of $M(T)$ for EuO and EuS throughout the entire temperature range from $T=0$ to Curie temperature $T_{C}$. In particular, our theoretical dependence $M(T)$ demonstrates a scaling behavior $M(T)\propto (T_{C}-T)^{β_*}$ with the scaling index $β_*\approx 1/3$ in a wide range of temperatures in agreement with the experimentally observed apparent scaling in EuO and EuS. The scaling behavior with $β_*\approx 1/3$ is manifested in the temperature range $T\lesssim T_{C}$ where corrections to the magnetization due to its fluctuations $δM (T)\lesssim M(T)$. To distinguish it from the narrow ``critical" range $T\approx T_{C}$ with $δM (T) > M(T)$, we term this $T$-range ``precritical". The precritical corrections $δM (T)$ are still large enough to affect the $M(T)$ behavior. The index $β_*$ fundamentally differs from the ``normal" scaling index $β_{MFA}=1/2$ predicted by the MFA, which neglects the magnetization fluctuations. We refer to the emerging in our theory apparent magnetization scaling with $β_*\approx 1/3$ as ``precritical anomalous".

description: Tolling is an age long revenue collection system institutionalised by public authorities for accumulating funds required for roads and bridges construction, maintenance and management. In spite of the merits of tolling as a major source of revenue in Nigeria, it was abruptly abrogated by the government few years ago because of reasons linked to ineffective governance, endemic corruption and lack of probity. The purpose of this paper is to make a case for responsible investment as an alternative funding mechanism for roads-bridges management (RBM) in Nigeria under a Public-Private Partnership (PPP) framework. The paper adopts a discursive approach, relying on government policy documents, journal articles, online resources, working papers and reports on tolling best practices. The numerical and non-numerical data were critically analysed using content analysis enriched by tables and figures. The first finding indicates there are enormous potentials in tolls collection from privately funded roads and bridges for responsible investors in Nigeria under the PPP framework. The second finding identifies eight (8) PPP typologies that could be explored by investors under government’s new tolling policy.

description: We develop a numerical methodology for the computation of entanglement measures for mixed quantum states. Using the well-known Schrödinger-HJW theorem, the computation of convex roof entanglement measures is reframed as a search for unitary matrices; a nonconvex optimization problem. To address this non-convexity, we modify a genetic algorithm, known in the literature as differential evolution, constraining the search space to unitary matrices by using a QR factorization. We then refine results using a quasi-Newton method. We benchmark our method on simple test problems and, as an application, compute entanglement between a system and its environment over time for pure dephasing evolutions. We also study the temperature dependence of Gibbs state entanglement for a class of block-diagonal Hamiltonians to provide a complementary test scenario with a set of entangled states that are qualitatively different. We find that the method works well enough to reliably reproduce entanglement curves, even for comparatively large systems. To our knowledge, the modified genetic algorithm represents the first derivative-free and non-convex computational method that broadly applies to the computation of convex roof entanglement measures.

description: The Tarantula Survey is an ambitious ESO Large Programme that has obtained multi-epoch spectroscopy of over 1,000 massive stars in the 30 Doradus region of the Large Magellanic Cloud. Here we introduce the scientific motivations of the survey and give an overview of the observational sample. Ultimately, quantitative analysis of every star, paying particular attention to the effects of rotational mixing and binarity, will be used to address fundamental questions in both stellar and cluster evolution.

How do the Richest 1% Own 50% of the National Wealth in an Integrated Walrasian Equilibrium and Neoclassical Growth Model
Creators: name: Zhang, Wei-Bin
Publisher: name: International Journal of Economic Behavior
Year: 2015

description: This paper proposes a dynamic economic model of heterogeneous households to explain economic mechanisms of how the richest one per cent of the population own 50% of national wealth. We explain inequality in a purely competitive economic environment with endogenous wealth and human capital accumulation. The production technologies and economic structure follow the Uzawa two-sector model. In this study a household’s disposable income is the traditional disposable income (which is the income that a household earns each period of time after taxes and transfers in the Solow model and many empirical studies) plus the value of the household’s wealth. By applying Zhang’s concept of disposable income and utility function, we describe consumers’ wealth accumulation and consumption behavior. We show how wealth accumulation, human capital accumulation, and division of labor, and time distribution interact with each other under perfect competition. We simulate the model with three groups of the people, the rich, the middle, and the poor whose shares of the population are, respectively, the 1 %, 69%, and 20%. We demonstrate the existence of an equilibrium point at which the rich 1% own more than half of the national wealth and the poor 20% less than 10% of the national wealth. The rich household works only 4 hours a day and the poor household 11 hours a day. We show how the system moves to the equilibrium from an initial state and confirm that the equilibrium point is stable. We also demonstrate how changes in the total factor productivity of the capital goods sector, the rich’s human capital utilization efficiency, the rich’s efficiency of learning through consuming, and the rich’s propensities to save, to consume, and to enjoy leisure, affect growth and inequality.

description: Recently the use of mobile technologies in Ecological Momentary Assessments (EMA) and Interventions (EMI) has made it easier to collect data suitable for intra-individual variability studies in the medical field. Nevertheless, especially when self-reports are used during the data collection process, there are difficulties in balancing data quality and the burden placed on the subjects. In this paper, we address this problem for a specific EMA setting which aims to submit a demanding task to subjects at high/low values of a self-reported variable. We adopt a dynamic approach inspired by control chart methods and design optimization techniques to obtain an EMA triggering mechanism for data collection which takes into account both the individual variability of the self-reported variable and of the adherence rate. We test the algorithm in both a simulation setting and with real, large-scale data from a tinnitus longitudinal study. A Wilcoxon-Mann-Whitney Rank Sum Test shows that the algorithm tends to have both a higher F1 score and utility than a random schedule and a rule-based algorithm with static thresholds, which are the current state-of-the-art approaches. In conclusion, the algorithm is proven effective in balancing data quality and the burden placed on the participants, especially, as the analysis performed suggest, in studies where data collection is impacted by adherence.

Publisher: name: Zenodo
Year: 2019

description: These slides were used to deliver a talk on 10 April 2019 at the SKA General Science Meeting on behalf of the SKA Cosmic Magnetism Science Working Group.

Abstract: The unprecedented sensitivity, angular resolution and broad bandwidth coverage of SKA radio polarimetric observations will allow us to address many long-standing mysteries in cosmic magnetism science. New science opportunities from SKA pathfinders are driving the development of new techniques in broadband radio polarimetry. In this talk, we will present the techniques that are being developed to process, analyze and interpret broadband polarimetric data from SKA pathfinders as well as the eventual SKA, and the exciting science they will enable. Topics such as wide-field polarimetric imaging, source finding in polarization, recent advances in rotation measure synthesis and Stokes QU fitting, and machine learning techniques will be covered.

description: This paper describes the application of Analytic Hierarchy Process (AHP) for unraveling customers’ motivation for churn of telecommunication network in Nigeria. By identifying, modeling and measuring of customers` churn motivations across four mobile telecommunication service providers in Nigeria. AHP was used to design a hierarchical model of seven criteria for customers` churning of network and investigates the relative priorities of the criteria through a pairwise comparison. The questionnaire were administered through convenient sampling to 480 mobile telecommunication customers and was completed and returned by 438 mobile phone subscribers in Lagos state, Nigeria, but only 408 copies were useful for the analysis of this study. The result shows that six out of the seven criteria have weight above 10% in their individual contribution to motivating customer churn behavior in the Nigeria telecommunication industry. The inefficient data/ internet plan criterion has the highest weight of 18.81% relative to the churn decision. Thus, AHP effectively supported modeling and analyzing subscribers` motivation toward good marketing decision for both the individual and the organization. It helps in developing an analytic and intelligible framework of decision-making on complex problem of customer churn in an emerging market like Nigeria.

Deciphering the heterogeneity and functional role of the cardiac stroma in health and disease
Creators: name: Tung, Lin Wei (Henry)
Publisher: name: University of British Columbia
Year: 2025

description: Heart failure is, in general, an inevitable outcome of ischemic heart disease and various cardiomyopathies. While this is largely attributed to the negligible regenerative capacity of the heart, the deterioration of cardiac function is driven by a myriad of dysregulated processes that culminate in chronic remodeling of the heart. In particular, the cardiac stroma, composed of interstitial mesenchymal cells, represents an important component of the cardiac niche and structure. It acts as a “double-edged” entity that plays a vital role in tissue repair and recovery of cardiac function, yet its involvement in driving pathological alterations leading to complete heart failure cannot be excluded. Thus, understanding the cardiac stroma and identifying mechanisms to alter its behaviour hold significant therapeutic potential. Here, we found that the cardiac stroma is a highly heterogeneous population consisted of multiple anatomically and functionally distinct entities. In response to acute ischemic injury, a subset of perivascular stromal cells known as pericytes acquire a transient signature indicative of increased fibrogenic activity and altered vascular maintenance, which is correlated with their dissociation from the vasculature and the ensuing vascular deterioration in the infarct. This regional response is supported by a niche that perpetuates pro-inflammatory, fibrogenic, and anti-angiogenic signaling beyond the completion of the myocardial scar. Dysregulation of the stroma and its secretome also potentiate the functional deterioration of the cardiac muscle. In chronic contexts such as hypertrophic cardiomyopathy, a subset of fibroblasts adopts an activated state similar to that of acute injuries and upregulates IGF-1 signaling to cardiomyocytes, and therefore inducing a hypertrophic response. Moreover, the abrogation of stromal signals regulating vascular growth and maintenance is indicative of compromised coronary circulation. Collectively, our work underlines the importance to develop strategies that target specific stromal populations and incorporate spatial considerations for effective treatment of cardiac pathologies.
