description: Several simulation projects in the area of production and logistics indicated that, although we have sophisticated input and output devices for computer supported modeling, physical models still play an important role for cognition and communication. We therefore introduce the concept of a Graspable User Interface that aims at combining two model worlds, the one inside the computer and a corresponding physical one in the outside world. Sensored user hands will couple physical objects of the real world with virtual objects, thus allowing fairly unrestricted manipulation and expression. In this way modeling with real physical objects can create an abstract virtual model. Some applications of this concept are presented. A further perspective for a new action oriented communication and learning with artifacts is envisioned.

description: Many smart systems depend on exact models of their environment. These are gained by tracking objects in their surroundings. When a highly precise system is only available for a small part of the environment, it can be enhanced with a second system to recover the unknown parts. This paper presents a method to recover loss of a precise (optical) tracking system by a less precise (inertial) tracking system. First the rotation from the inertial measurement unit (IMU) and the optical system are aligned. A second step integrates the IMU acceleration two times and removes both times the drift by known initial and end values (first integration: velocity, second integration: position) from optical tracking. The error is backpropagated continuously.

description: Nowadays large spectroscopic surveys, like the Gaia-ESO Survey (GES), provide unique stellar databases for better investigating the formation and evolution of our Galaxy. Great attention must be paid to the accuracy of the basic stellar properties derived: large uncertainties in stellar parameters lead to large uncertainties in abundances, distances and ages. Asteroseismology has a key role in this context: when seismic information is combined with information derived from spectroscopic analysis, highly precise constraints on distances, masses, extinction and ages of Red Giants can be obtained. In the light of this promising joint-action, we started the CoRoT-GES collaboration. We present a set of 1,111 CoRoT stars, observed by GES from December 2011 to July 2014, these stars belong to the CoRoT field LRc01, pointing at the inner Galactic Disk. Among these stars, 534 have reliable global seismic parameters. By combining seismic informations and spectroscopy, we derived precise stellar parameters, ages, kinematic and orbital parameters and detailed element abundances for this sample of stars. We also show that, thanks to asteroseismology, we are able to obtain a higher precision than what can be achieved by the standard spectroscopic means. This sample of CoRoT Red Giants, spanning Galactocentric distances from 5 to 8 kpc and a wide age interval (1-13 Gyrs), provides us a representative sample for the inner disk population.

Strain induced topological phase transition at zigzag edges of monolayer transition-metal dichalcogenides

description: The effect of strain in zigzag ribbons of monolayer transition-metal dichalcogenides with induced superconductivity is studied using a minimal 3-band tight-binding model. The unstrained system shows a topological phase with Majorana zero modes localized at the boundaries of the one-dimensional (1D) zigzag edges. By direct inspection of the spectrum and wave functions we examine the evolution of the topological phase as an in-plane, uniaxial deformation is imposed. It is found that strain shifts the energy of 1D edge states, thus causing a topological phase transition which eliminates the Majorana modes. For realistic parameter values, we show that the effect of strain can be changed from completely destructive -- in which case a small built in strain is enough to destroy the topological phase -- to a situation where strain becomes an effective tuning parameter which can be used to manipulate Majorana zero modes. These two regimes are accessible by increasing the value of the applied Zeeman field within realistic values. We also study how strain effects are affected by the chemical potential, showing in particular how unwanted effects can be minimized. Finally, as a cross-check of the obtained results, we reveal the connection between 1D Majorana zero modes in the zigzag edge and the multi-band Berry phase, which serves as a topological invariant of this system.

title: Teaching & Learning Britishness:
Encountering and negotiating discourses of identities and belongings through critical pedagogy
Creators: name: Habib, Sadia
Publisher: name: Goldsmiths, University of London
Year: 2016
Subjects: subject: Britishness, Fundamental British Values, identity, belonging, teaching, learning, critical pedagogy, nation, place, transnational, ethnicity, race, racism, multiculturalism, class, art, education

description: Teaching Britishness and ‘Fundamental British Values’ is a policy requirement increasingly placed on educational institutions. Yet the literature shows Britishness is fluid, evolving and often difficult to define for White British and ethnic minority youth, as well as for teachers, raising theoretical and pedagogical concerns about how best to respond to political initiatives.  By examining the pedagogies employed by two Art classes in a southeast London school, this research aims to address the implications of Britishness exploration on young people’s relationships with and within multicultural Britain.  This ethnographic arts-based educational research examines (i) the complexities of teaching and learning Britishness, and (ii) young people’s discourses of Britishness and belonging.  

Through emotive artwork created by students, interviews with teachers and paired students, and extensive questionnaires, moving and personal insights into the significances of everyday racialised and classed belongings are investigated.  The key findings show young people’s experiences of local and global identities inform their notions of national identity.  Students’ sense of Britishness is deeply connected to intersectional and multiple experiences of social class, race and local attachments.  Their national identity is often dwarfed by their local identity, and transnational postcolonial identities are also shown to impact upon young peoples’ ways of belonging to Britain.   

The research describes and supports critical pedagogical approaches to exploring identities and belongings.  The emphasis on student voice, respectful and caring dialogue, and collaborative communication led to meaningful and engaged individual and collective critical reflections on students’ stories of Britishness.  The research shows teachers often require guidance and support on teaching critically about multiculturalism and social inequalities.  The research presents students engaging with identity issues, advancing their own viewpoints, learning about alternative perspectives, and strengthening bonds with peers and teachers.  Students felt empowered by having their critical counter-narratives validated and valued.  Where students hear others’ stories and tell their own, schools can become critical sites of opportunity for reflection, resistance and hopeful futures.

The trace is another invariant for UMTCs which depends only on modular data, and contains the expression of the Frobenius-Schur indicator as a special case. Furthermore, we discuss some applications of the trace formula to the realizability problem of modular data and to the classification of UMTCs.

description: Filtering relevant documents with respect to entities is an essential task in the context of knowledge base construction and maintenance. It entails processing a time-ordered stream of documents that might be relevant to an entity in order to select only those that contain vital information. State-of-the-art approaches to document filtering for popular entities are entity-dependent: they rely on and are also trained on the specifics of differentiating features for each specific entity. Moreover, these approaches tend to use so-called extrinsic information such as Wikipedia page views and related entities which is typically only available only for popular head entities. Entity-dependent approaches based on such signals are therefore ill-suited as filtering methods for long-tail entities. In this paper we propose a document filtering method for long-tail entities that is entity-independent and thus also generalizes to unseen or rarely seen entities. It is based on intrinsic features, i.e., features that are derived from the documents in which the entities are mentioned. We propose a set of features that capture informativeness, entity-saliency, and timeliness. In particular, we introduce features based on entity aspect similarities, relation patterns, and temporal expressions and combine these with standard features for document filtering. Experiments following the TREC KBA 2014 setup on a publicly available dataset show that our model is able to improve the filtering performance for long-tail entities over several baselines. Results of applying the model to unseen entities are promising, indicating that the model is able to learn the general characteristics of a vital document. The overall performance across all entities---i.e., not just long-tail entities---improves upon the state-of-the-art without depending on any entity-specific training data.

description: We examine the explicit business model preferences and implicit mental representations of entrepreneurship in the early phase of the crisis. We find that the crisis comes with adaptations in both. During crisis, society is open for new business models, even though people increasingly rely on established economic actors instead of opening up towards newly founded firms. We conclude that the early and sudden impact of the crisis influences the entrepreneurial culture onwards and therefore potentially future entrepreneurial activities.
Anisotropy of a Cubic Ferromagnet at Criticality

Year: 2016
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: Critical fluctuations change the effective anisotropy of cubic ferromagnet near the Curie point. If the crystal undergoes phase transition into orthorhombic phase and the initial anisotropy is not too strong, reduced anisotropy of nonlinear susceptibility acquires at $T_c$ the universal value $δ_4^* = {{2v^*} \over {3(u^* + v^*)}}$ where $u^*$ and $v^*$ -- coordinates of the cubic fixed point on the flow diagram of renormalization group equations. In the paper, the critical value of the reduced anisotropy is estimated within the pseudo-$ε$ expansion approach. The six-loop pseudo-$ε$ expansions for $u^*$, $v^*$, and $δ_4^*$ are derived for the arbitrary spin dimensionality $n$. For cubic crystals ($n = 3$) higher-order coefficients of the pseudo-$ε$ expansions obtained turn out to be so small that use of simple Padé approximants yields reliable numerical results. Padé resummation of the pseudo-$ε$ series for $u^*$, $v^*$, and $δ_4^*$ leads to the estimate $δ_4^* = 0.079 \pm 0.006$ indicating that detection of the anisotropic critical behavior of cubic ferromagnets in physical and computer experiments is certainly possible.

description: We present the current status of the analytic theory of brown dwarf evolution and the lower mass limit of the hydrogen burning main sequence stars. In the spirit of a simplified analytic theory we also introduce some modifications to the existing models. We give an exact expression for the pressure of an ideal non-relativistic Fermi gas at a finite temperature, therefore allowing for non-zero values of the degeneracy parameter ($ψ= \frac{kT}{μ_{F}}$, where $μ_{F}$ is the Fermi energy). We review the derivation of surface luminosity using an entropy matching condition and the first-order phase transition between the molecular hydrogen in the outer envelope and the partially-ionized hydrogen in the inner region. We also discuss the results of modern simulations of the plasma phase transition, which illustrate the uncertainties in determining its critical temperature. Based on the existing models and with some simple modification we find the maximum mass for a brown dwarf to be in the range $0.064M_\odot-0.087M_\odot$. An analytic formula for the luminosity evolution allows us to estimate the time period of the non-steady state (i.e., non-main sequence) nuclear burning for substellar objects. Standard models also predict that stars that are just above the substellar mass limit can reach an extremely low luminosity main sequence after at least a few million years of evolution, and sometimes much longer. We estimate that $\simeq 11 \%$ of stars take longer than $10^7$ yr to reach the main-sequence, and $\simeq 5 \%$ of stars take longer than $10^8$ yr.

description: We study the impact fintech startups have on the performance and the default risk of traditional financial institutions. We find a positive relationship between fintech startup formations and incumbent institutions’ performance for the period from 2005 to 2018 and a large sample of financial institutions from 87 countries. We further analyze the link between fintech startup formations and the default risk of traditional financial institutions. Fintech startup formations decreases stock return volatility of incumbent institutions and decreases the systemic risk exposure of financial institutions. Our findings indicate that the development of fintech startups should be monitored very closely by legislators and financial supervisory authorities, because fintechs not only have a positive effect on the financial sector’s performance, but can also improve financial stability relative to the status quo.

description: The dynamics of $η$ meson produced in proton-induced nuclear reactions via the decay of N$^{\ast}(1535)$ has been investigated within the Lanzhou quantum molecular dynamics transport model (LQMD). The in-medium modifications of the $η$ production in dense nuclear matter are included in the model, in which an attractive $η$-nucleon potential is implemented. The impact of the $η$ optical potential on the $η$ dynamics is investigated. It is found that the attractive potential leads to the reduction of high-momentum (kinetic energy) production from the spectra of momentum distributions and inclusive cross sections and increasing the reabsorption process by surrounding nucleons.

description: The history of technology has concerned itself so far to only a minor extent with the linking of computers, terminals and other teleconnections, or with the genesis of special data communications networks and information systems, despite the fact that these have been under development for over 40 years. While some interesting work has been produced on specific issues and network types, large areas of computer communications history have not been subjected to any major treatment as yet. There is a consequent lack of any comprehensive overview of the so-called "merger" of information and communications technology. The reasons for this abstinence seem to be a product firstly of the intermediate position that this technology occupies between telecommunications and computer technology. Secondly, however, the fixation on the part of historians on the early phases of computer technology and the relative lack of attention paid to systemic aspects of the origins and development of computer technology, or to more complex sociotechnical applications concepts such as timesharing or distributed processing has also played a role here. The history of computing is still the history of hardware and not data processing as such. In view of these gaps in research and the lack of specialization and controversy in this field, I should like in the following to outline the development of computer communications, whereby the central focus should be on questions relating to the explanatory power, the limits and the shortcomings of more recent technohistorical approaches such as the "genesis of technology", the analysis of technological visions [Technikleitbilder] and especially "large system theory".

description: GitHub is the largest source code repository in the world. It provides a git-based source code management platform and also many features inspired by social networks. For example, GitHub users can show appreciation to projects by adding stars to them. Therefore, the number of stars of a repository is a direct measure of its popularity. In this paper, we use multiple linear regressions to predict the number of stars of GitHub repositories. These predictions are useful both to repository owners and clients, who usually want to know how their projects are performing in a competitive open source development market. In a large-scale analysis, we show that the proposed models start to provide accurate predictions after being trained with the number of stars received in the last six months. Furthermore, specific models---generated using data from repositories that share the same growth trends---are recommended for repositories with slow growth and/or for repositories with less stars. Finally, we evaluate the ability to predict not the number of stars of a repository but its rank among the GitHub repositories. We found a very strong correlation between predicted and real rankings (Spearman's rho greater than 0.95).

Grundzüge des ökonomisch-sozialen Entwicklungspfads reifer Industriegesellschaften, das von der französischen Regulations-Schule nach dem Autobauer Henry Ford als Fordismus bezeichnet worden ist, sind im Wandel begriffen. Dieser Wandel wird in der öffentlichen Debatte sowohl analytisch als auch konstruktiv politisch aus verschiedenen Perspektiven thematisiert. Für das feministische Denken stellt der Wandel Fragen seiner politischen Beurteilung, denn lange Zeit richtete sich die Kritik gegen die im Fordismus eingeschriebene Geschlechterhierarchie. Angesichts des fundamentalen Wandels der industriegesellschaftlichen in eine postindustriegesellschaftliche Konfiguration muß sich feministisches Denken in den Debatten über die Ablösung der Arbeitsgesellschaft durch eine Tätigkeitsgesellschaft verorten, also eine Gesellschaft, die – über Erwerbsarbeit hinaus - das gesamte Spektrum menschlicher Tätigkeiten zu würdigen weiß. Dabei ist es unausweichlich, dass sich feministisches Denken noch einmal mit dem Stellenwert auseinandersetzt, den sie der Erwerbsarbeit im feministischen Projekt zugesprochen hat. Die folgenden Überlegungen sollen zu dieser notwendigen Auseinandersetzung beitragen.

description: Dehydration of water from surface Mg2+ is most likely the rate-limiting step in the dolomite growth at low temperature. Here, we investigate the role of polysaccharide in this step using classical molecular dynamics (MD) calculations. Free energy (potential of mean force, PMF) calculations have been performed for water molecules leaving the first two hydration layers above the dolomite (104) surface under the following three conditions: without catalyst, with monosaccharide (mannose) and with oligosaccharide (three units of mannose). MD simulations reveal that there is no obvious effect of monosaccharide in lowering the dehydration barrier for surface Mg2+. However, we found that there are metastable configurations of oligosaccharide, which can decrease the dehydration barrier of surface Mg2+ by about 0.7-1.1 kcal/mol. In these configurations, the molecule lies relatively flat on the surface and forms a bridge shape. The hydrophobic space near the surface created by the non-polar -CH groups of the oligosaccharide in the bridge conformation is the reason for the observed reduction of dehydration barrier.

Der sinnlichen Wahrnehmung und Überprüfung realstofflicher Phänomene wird eine zentrale Bedeutung für das Begreifen und Beurteilen komplexer Zusammenhänge zuerkannt. An Beispielen aus der Steuerungstechnik wird eine schrittweise, nachvollziehbare und überprüfbare Abstraktion, ausgehend von konkret erfahrbaren Zusammenhängen, zu physikalischen, funktionalen und numerischen Modellen demonstriert.

description: A dynamic model of the Galaxy is constructed based on kinematic data for masers with trigonometric parallaxes. Maser data is used to compute the model potential in the Galactic plane. The potential is then generalized to three dimensions assuming the existence of a third quadratic integral of motion. The resulting Galactic model potential is of Stäckel's type. The corresponding space density function is determined from Poisson's equation.

description: We show that it is possible to significantly reduce quadrupole and tensor polarizability shifts of a clock transition by operating at a judiciously chosen field-insensitive point. In some cases shifts are almost completely eliminated making the transition an effective J = 0 to J = 0 candidate. This significantly improves the feasibility of a recent proposal for clock operation with large ion crystals. For such multi-ion clocks, geometric constraints and selection rules naturally divide clock operation into two categories based on the orientation of the magnetic field. We discuss the limitations imposed on each type and how calibrations might be carried out for clock operation.

description: Magnetic excitation in a spin dimer system on a bilayer honeycomb lattice is investigated in the presence of a zigzag edge, where disordered and ordered phases can be controlled by a quantum phase transition. In analogy with the case of graphene with a zigzag edge, a flat edge magnon mode appears in the disordered phase. In an ordered phase, a finite magnetic moment generates a mean-field potential to the magnon. Since the potential is nonuniform on the edge and bulk sites, it affects the excitation, and the dispersion of the edge mode deviates from the flat shape. We investigate how the edge magnon mode evolves when the phase changes through the quantum phase transition and discuss the similarities to ordered spin systems on a monolayer honeycomb lattice.

description: It is important to measure selected biochemical parameters in the body fluids to estimate the energy status and relate it with metabolic disorders, milk production and infertility. In 10 cows (F1 Holstein x Cebu) on grazing conditions with mineral and molasses supplementation, samplings were done during the following periods: 2-3 weeks prepartum, 3 weeks, 2, 3, 4 and 7 months postpartum. In each period physical examinations of animals, milk yield and body condition were registered.

Modeling Fractal Structure of Systems of Cities Using Spatial Correlation Function

description: This paper proposes a new method to analyze the spatial structure of urban systems using ideas from fractals. Regarding a system of cities as a set of "particles" distributed randomly on a triangular lattice, we construct a spatial correlation function of cities. Suppose that the spatial correlation follows the power law. It can be proved that the correlation exponent is the second order generalized dimension. The spatial correlation model is applied to the system of cities in China. The results show that the Chinese urban system can be described by the correlation dimension ranging from 1.3 to 1.6. The fractality of self-organized network of cities in both the conventional geographic space and the "time" space is revealed with the empirical evidence. The spatial correlation analysis is significant in that it is applicable to both large and small sizes of samples and can be used to link different fractal dimensions in urban study, including box dimension and radial dimension.

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We consider quark-photon correlations that have been proposed as a source for single-spin asymmetries in inclusive deep-inelastic scattering. A new sum rule for these correlators is derived and its phenomenological consequences are discussed. The results are interpreted within the context of an intuitive 'electrodynamic lensing' picture.

description: The availability of Global Navigation Satellite Systems (GNSS) enables sophisticated vehicle guidance and advisory systems such as Intelligent Speed Adaptation (ISA) systems. In ISA systems, it is essential to be able to position vehicles within a road network. Because digital road networks as well as GNSS positioning are often inaccurate, a technique known as map matching is needed that aims to use this inaccurate data for determining a vehicle’s real road-network position. Then, knowing this position, an ISA system can compare speed with the speed limit in effect and take measures against speeding. This paper presents an online map matching algorithm with an extensive number of weighting parameters that allow better determination of a vehicle’s road network position. The algorithm uses certainty value to express its belief in the correctness of its results. The algorithm was designed and implemented to be used in the large scale ISA project ”Spar på farten” . Using test data and data collected from project participants, the algorithm’s performance is evaluated. It is shown that algorithm performs correctly 95 % of the time and is capable of handling GNSS positioning errors in a conservative manner.

Structure in Sheared Supercooled Liquids: Dynamical Rearrangements of an Effective System of Icosahedra

description: We consider a binary Lennard-Jones glassformer whose super-Arrhenius dynamics are correlated with the formation of particles organized into icosahedra under simple steady state shear. We recast this glassformer as an effective system of icosahedra [Pinney et al. J. Chem. Phys. 143 244507 (2015)]. From the observed population of icosahedra in each steady state, we obtain an effective temperature which is linearly dependent on the shear rate in the range considered. Upon shear banding, the system separates into a region of high shear rate and a region of low shear rate. The effective temperatures obtained in each case show that the low shear regions correspond to a significantly lower temperature than the high shear regions. Taking a weighted average of the effective temperature of these regions (weight determined by region size) yields an estimate of the effective temperature which compares well with an effective temperature based on the global mesocluster population of the whole system.
