description: These are the lecture notes from the 26th Winter School "Geometry and Physics", Czech Republic, Srni, January 14 - 21, 2006. These lectures are an introduction into the realm of generalized geometry based on the tangent plus the cotangent bundle. In particular we discuss the relation of this geometry to physics, namely to two-dimensional field theories. We explain in detail the relation between generalized complex geometry and supersymmetry. We briefly review the generalized Kahler and generalized Calabi-Yau manifolds and explain their appearance in physics.

Performance of discrete heat engines and heat pumps in finite time

description: The performance in finite time of a discrete heat engine with internal friction is analyzed. The working fluid of the engine is composed of an ensemble of noninteracting two level systems. External work is applied by changing the external field and thus the internal energy levels. The friction induces a minimal cycle time. The power output of the engine is optimized with respect to time allocation between the contact time with the hot and cold baths as well as the adiabats. The engine's performance is also optimized with respect to the external fields. By reversing the cycle of operation a heat pump is constructed. The performance of the engine as a heat pump is also optimized. By varying the time allocation between the adiabats and the contact time with the reservoir a universal behavior can be identified. The optimal performance of the engine when the cold bath is approaching absolute zero is studied. It is found that the optimal cooling rate converges linearly to zero when the temperature approaches absolute zero.

Matching People and Groups; Recruitment and Selection in Online Games

description: Massively multiplayer online games (MMOGs) have great potential as sites for research within the social and behavioral sciences and human-computer interaction. This is because “guilds” — semi-persistent groups in online games — are much like groups in real organizations. In this paper, we examine how groups and individuals find appropriate matches and whether appropriate matches lead newcomers to stay longer in their groups in an online game environment. Results from archival data, observation, and survey in the game World of Warcraft (WoW) indicate that different selection methods lead to person-group fit for social and task-oriented characteristics and good fit leads recruits to stay longer in their group. In particular, recruitment of new members to task-oriented guilds was most successful when brief interactions were used whereas recruitment to social-oriented guilds was most successful when probationary periods and referrals were used.

description: We present a protocol to selectively decouple, recouple, and engineer effective couplings in mesoscopic dipolar spin networks. In particular, we develop a versatile protocol that relies upon magic angle spinning to perform Hamiltonian engineering. By using global control fields in conjunction with a local actuator, such as a diamond Nitrogen Vacancy center located in the vicinity of a nuclear spin network, both global and local control over the effective couplings can be achieved. We show that the resulting effective Hamiltonian can be well understood within a simple, intuitive geometric picture, and corroborate its validity by performing exact numerical simulations in few-body systems. Applications of our method are in the emerging fields of two-dimensional room temperature quantum simulators in diamond platforms, as well as in dipolar coupled polar molecule networks.

description: Correlation filters are special classifiers designed for shift-invariant object recognition, which are robust to pattern distortions. The recent literature shows that combining a set of sub-filters trained based on a single or a small group of images obtains the best performance. The idea is equivalent to estimating variable distribution based on the data sampling (bagging), which can be interpreted as finding solutions (variable distribution approximation) directly from sampled data space. However, this methodology fails to account for the variations existed in the data. In this paper, we introduce an intermediate step -- solution sampling -- after the data sampling step to form a subspace, in which an optimal solution can be estimated. More specifically, we propose a new method, named latent constrained correlation filters (LCCF), by mapping the correlation filters to a given latent subspace, and develop a new learning framework in the latent subspace that embeds distribution-related constraints into the original problem. To solve the optimization problem, we introduce a subspace based alternating direction method of multipliers (SADMM), which is proven to converge at the saddle point. Our approach is successfully applied to three different tasks, including eye localization, car detection and object tracking. Extensive experiments demonstrate that LCCF outperforms the state-of-the-art methods. The source code will be publicly available. https://github.com/bczhangbczhang/.
Enrichment of the Intergalactic Medium by Radiation Pressure Driven Dust Efflux

description: The presence of metals in hot cluster gas and in Ly-alpha absorbers, as well as the mass-metallicity relation of observed galaxies, suggest that galaxies lose a significant fraction of their metals to the intergalactic medium (IGM). Theoretical studies of this process have concentrated on metal removal by dynamical processes or supernova-driven winds. Here, we investigate the enrichment of the IGM by the expulsion of dust grains from galaxies by radiation pressure. We use already completed cosmological simulations, to which we add dust assuming that most dust can reach the equilibrium point between radiation pressure and gravitational forces. We find that the expulsion of dust and its subsequent (partial) destruction in the IGM can plausibly account for the observed level of C and Si enrichment of the z=3 IGM. At low-z, dust ejection and destruction could explain a substantial fraction of the metals in clusters, but it cannot account for all of the chemical species observed. Dust expelled by radiation pressure could give clusters a visual opacity of up to 0.2-0.5 mag in their central regions even after destruction by the hot intracluster medium; this value is interestingly close to limits and claimed observations of cluster extinction. We also comment on the implications of our results for the opacity of the general IGM. Finally, we suggest a possible `hybrid' scenario in which winds expel gas and dust into galaxy halos but radiation pressure distributes the dust uniformly through the IGM.

description: It is shown that every symplectic map of $R^2n$ can be approximated, in the $C^infty$-topology, on any compact set, by some iteration of some map of the form $(x,y)mapsto (y+eta, -x +Phi(y))$ where $xin R^n$, $yin R^n$, and $Phi$ is a polynomial $R^nrightarrow R^n$ and $etain R^n$ is a constant vector. For the case of area-preserving maps (i.e. $n=1$), it is shown how this result can be applied to prove that $C^r$-universal maps (a map is universal if its iterations approximate dynamics of all $C^r$-smooth area-preserving maps altogether) are dense (in the $C^r$-topology) in the Newhouse regions.

description: Balancing the needs of information distributors and their audiences has grown harder in the age of the Internet. While the demand for attention continues to increase rapidly with the volume of information and communication, the supply of human attention is relatively fixed. Markets are a social institution for efficiently balancing supply and demand of scarce resources. Charging a price for sending messages may help discipline senders from demanding more attention than they are willing to pay for. Price may also help recipients estimate the value of a message before reading it. We report the results of two laboratory experiments to explore the consequences of a pricing system for electronic mail. Charging postage for email causes senders to be more selective and send fewer messages. However, recipients did not use the postage paid by senders as a signal of importance. These studies suggest markets for attention have potential, but their design needs more work.

Mapping the Space of API Design Decisions
Creators: name: Stylos, Jeffrey

Year: 2007
Subjects: Applied Computer Science

description: When creating new application programming interfaces (APIs), designers must make many decisions. These decisions affect the quality of the resulting APIs in terms of performance (such as speed and memory usage), power (expressiveness, extensibility and evolvability) and usability (learnability, productivity and error prevention). Experienced API designers have written recommendations on how to design APIs, offering their opinions on various API design decisions. Additionally, empirical research has begun to measure the usability tradeoffs of specific design decisions. While previous work has offered specific suggestions, there has not been a clear description of the design space of all possible API design decisions, or the quality attributes that these decisions affect. This paper puts existing API design recommendations into context by mapping out the space of API design decisions and API quality attributes.

description: We study by means of molecular dynamics simulations of periodic shear cells, the influence of particle shape on the global mechanical behavior of dense granular media. Results at macro-mechanical level show that for large shear deformation samples with elongated particles, independent of their initial orientation, reach the same stationary value for both shear force and void ratio. At the micro-mechanical level the stress, the fabric and the inertia tensors of the particles are used to study the evolution of the media. In the case of isotropic particles the direction of the principal axis of the fabric tensor is aligned with the one of the principal stress, while for elongated particles the fabric orientation is strongly dependent on the orientation of the particles. The shear band width is shown to depend on the particle shape due to the tendency of elongated particles to preferential orientations and less rotation.

The tunneling potential for field emission from nanotips

Publisher: name: arXiv

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: In the quasi-planar approximation of field emission, the potential energy due to an external electrostatic field $E_0$ is expressed as $-e γE_0 Δs$ where $Δs$ is the perpendicular distance from the emission site and $γ$ is the local field enhancement factor on the surface of the emitter. We show that for curved emitter tips, the current density can be accurately computed if terms involving $(Δs/R_2)^2$ and $(Δs/R_2)^3$ are incorporated in the potential where $R_2$ is the second (smaller) principle radius of curvature. The result is established analytically for the hemiellipsoid and hyperboloid emitters and it is found that for sharply curved emitters, the expansion coefficients are equal and coincide with that of a sphere. The expansion seems to be applicable to generic emitters as demonstrated numerically for an emitter with a conical base and quadratic tip. The correction terms in the potential are adequate for $R_a \gtrapprox 2$ nm for local field strengths of $5$ V/nm or higher. The result can also be used for nano-tipped emitter arrays or even a randomly placed bunch of sharp emitters.

description: Extracting useful knowledge from large network datasets has become a fundamental challenge in many domains, from scientific literature to social networks and the web. We introduce Apolo, a system that uses a mixed-initiative approach— combining visualization, rich user interaction and machine learning—to guide the user to incrementally and interactively explore large network data and make sense of it. Apolo engages the user in bottom-up sensemaking to gradually build up an understanding over time by starting small, rather than starting big and drilling down. Apolo also helps users find relevant information by specifying exemplars, and then using a machine learning method called Belief Propagation to infer which other nodes may be of interest. We evaluated Apolo with twelve participants in a between-subjects study, with the task being to find relevant new papers to update an existing survey paper. Using expert judges, participants using Apolo found significantly more relevant papers. Subjective feedback of Apolo was also very positive.

description: We present a numerical study of noncolloidal spherical and rigid particles suspended in Newtonian, shear thinning and shear thickening fluids employing an Immersed Boundary Method. We consider a linear Couette configuration to explore a wide range of solid volume fractions ($0.1\le Φ\le 0.4$) and particle Reynolds Numbers ($0.1\le Re_p \le 10$). We report the distribution of solid and fluid phase velocity and solid volume fraction and show that close to the boundaries inertial effects result in a significant slip velocity between the solid and fluid phase. The local solid volume fraction profiles indicate particle layering close to the walls, which increases with the nominal $Φ$. This feature is associated with the confinement effects. We calculate the probability density function of local strain rates and compare their mean value with the values estimated from the homogenization theory of \cite{Chateau08}, indicating a reasonable agreement in the Stokesian regimes. Both the mean value and standard deviation of the local strain rates increase primarily with the solid volume fraction and secondarily with the $Re_p$. The wide spectrum of the local shear rate and its dependency on $Φ$ and $Re_p$ points to the deficiencies of the mean value of the local shear rates in estimating the rheology of these noncolloidal complex suspensions. Finally, we show that in the presence of inertia, the effective viscosity of these noncolloidal suspensions deviates from that of Stokesian suspensions. We discuss how inertia affects the microstructure and provide a scaling argument to give a closure for the suspension shear stress for both Newtonian and power-law suspending fluids. The stress closure is valid for moderate particle Reynolds numbers, $ O(Re_p)\sim 10$.
Doubled Geometry and T-Folds

Year: 2006
Subjects: subject: High Energy Physics - Theory (hep-th)

description: The doubled formulation of string theory, which is T-duality covariant and enlarges spacetime with extra coordinates conjugate to winding number, is reformulated and its geometric and topological features examined. It is used to formulate string theory in T-fold backgrounds with T-duality transition functions and a quantum implementation of the constraints of the doubled formalism is presented. This establishes the quantum equivalence to the usual sigma-model formalism for world-sheets of arbitrary genus, provided a topological term is added to the action. The quantisation involves a local choice of polarisation, but the results are independent of this. The natural dilaton of the doubled formalism is duality-invariant and so T-duality is a perturbative symmetry for the perturbation theory in the corresponding coupling constant. It is shown how this dilaton is related to the dilaton of the conventional sigma-model which does transform under T-duality. The generalisation of the doubled formalism to the superstring is given and shown to be equivalent to the usual formulation. Finally, the formalism is generalised to one in which the whole spacetime is doubled.

description: We present a catalogue of 147 serendipitous X-ray sources selected to have hard spectra (alpha < 0.5) from a survey of 188 ROSAT fields. Such sources must be the dominant contributors to the X-ray background at faint fluxes. We have used Monte Carlo simulations to verify that our technique is very efficient at selecting hard sources: the survey has > 10 times as much effective area to hard sources as it has to soft sources above a 0.5 - 2 keV flux level of 10^-14 erg/cm^2/s. The distribution of best fit spectral slopes of the hard sources suggests that a typical ROSAT hard source in our survey has a spectral slope alpha ~0. The hard sources have a steep number flux relation (dN/dS propto S^-gamma with a best fit value of gamma = 2.72 +- 0.12) and make up about 15% of all 0.5 - 2 keV sources with S > 10^-14 erg/cm^2/s. If their N(S) continues to fainter fluxes, the hard sources will comprise ~ 40% of sources with 5 10^-15 < S < 10^-14. The population of hard sources can therefore account for the harder average spectra of ROSAT sources with S < 10^-14. They probably make a strong contribution to the X-ray background at faint fluxes and could be the solution to the X-ray background spectral paradox.

description: Quasi free standing monolayer graphene (QFMLG) grown on SiC by selective Si evaporation from the Si-rich SiC(0001) face and H intercalation displays irregularities in STM and AFM analysis, appearing as localized features, which we previously identified as vacancies in the H layer coverage [Y Murata, et al. Nano Res, in press, DOI: 10.1007/s12274-017-1697-x]. The size, shape, brightness, location, and concentration of these features, however, are variable, depending on the hydrogenation conditions. In order to shed light on the nature of these features, in this work we perform a systematic Density Functional Theory study on the structural and electronic properties of QFMLG with defects in the H coverage arranged in different configurations including up to 13 vacant H atoms, and show that these generate localized electronic states with specific electronic structure. Based on the comparison of simulated and measured STM images we are able to associate different vacancies of large size (7-13 missing H) to the different observed features. The presence of large vacancies is in agreement with the tendency of single H vacancies to aggregate, as demonstrated here by DFT results. This gives some hints into the hydrogenation process. Our work unravels the structural diversity of defects of H coverage in QFMLG and provides operative ways to interpret the variety in the STM images. The energy of the localized states generated by these vacancies is tunable by means of their size and shape, suggesting applications in nano- and opto-electronics.

description: Contrary to the antiferromagnetic and insulating character of bulk NiO, one-dimensional chains of this material can become half-metallic due to the lower coordination of their atoms. Here we present ab initio electronic structure and quantum transport calculations of ideal infinitely long NiO chains and of more realistic short ones suspended between Ni electrodes. While infinite chains are insulating, short suspended chains are half-metallic minority-spin conductors which display very large magnetoresistance and a spin-valve behaviour controlled by a single atom.

description: The first step in any formalism that aims to connect a many-nucleon theory of nucleon-nucleus scattering and the concept of an optical model potential in the sense pioneered by Feshbach is to explain what is meant by the optical model wavefunction. By definition this is a function of a single space coordinate plus a set of single nucleon internal variables. This article gives a critique of the definitio as it is frequently expressed in 2nd Quantisation language and suggest a new definition which is more consistent with the requirements of antisymmetry and translational invariance. A modification of the time-dependent Green's function formalism is suggested.

title: Transatlantic Sensationalism and the First Printing of Rubén Darío’s “A Roosevelt”
Creators: name: Reynolds, Andrew
Publisher: name: Utah State University
Year: 2015

description: Nicaraguan poet Rubén Darío once posed the following question concerning the effects of U.S. domination of Cuba 15 years following the Spanish American War: “¿Qué espectáculo ofrece hoy día ese pueblo al espectador imparcial? El de una colonia disimulada donde a las aspiraciones de veinte años de lucha ha sucedido un oscuro servilismo al oro yanqui” (“Refutación” 111). Darío suggests that readers visually perceive the situation, that they trust “impartial spectators” in order to truly comprehend the U.S. domination in the region. Spectacles are events based on the optics of the consuming observers; viewers who, at their own leisure, decipher visual productions and performances. Unsurprisingly, Darío himself is the informed spectator and enlightens readers to the colonialist and financial burdens imposed on Cuba. The poet continually implemented this didactic maneuver to uncover the “spectacles” of U.S. domination following el desastre of 1898. The spectacle of the “lucha” of U.S.-Latin American relations, as construed by Darío, is no more evident than in the first printing of his seminal poem “A Roosevelt” in Madrid magazine Helios in 1904.1

Internal Audit in Moroccan Regional Education and Training Academies (AREF) : An empirical study
Creators: name: Mohamed ESSAOUDI
name: Raja LOTFI
Publisher: name: Zenodo
Year: 2024

description: Over the past two decades, the Moroccan education system has been under considerable pressure to both improve the quality of its services, and make more effective and efficient use of the resources at its disposal. This context has necessitated the updating of the management control system and the introduction of internal control and audit systems. The latter has become a key device at the service of the national education system's top management. Our research studies the late implementation and gradual development of the internal audit function in Moroccan regional education and training academies (AREF), and analyzes its descriptive, structural, organizational and functional characteristics. Data was collected through a survey of financial affairs inspectors (IAF) in the internal audit units (UAI) of nine AREFs. The results of the study highlight the similarities and differences, as well as the gaps and shortcomings, that characterize internal auditing in AREFs compared with private organizations.

Making Mashups with Marmite: Towards End-User Programming for the Web
Creators: name: Wong, Jeffrey

Publisher: name: Carnegie Mellon University
Year: 2007
Subjects: Applied Computer Science

description: There is a tremendous amount of web content available today, but it is not always in a form that supports end-users’ needs. In many cases, all of the data and services needed to accomplish a goal already exist, but are not in a form amenable to an end-user. To address this problem, we have developed an end-user programming tool called Marmite, which lets end-users create so-called mashups that repurpose and combine existing web content and services. In this paper, we present the design, implementation, and evaluation of Marmite. An informal user study found that programmers and some spreadsheet users had little difficulty using the system.

Discreteness of dyonic dilaton black holes

description: We show that there are two classes of solutions that describe static spherically symmetric dyonic dilaton black holes with two nonsingular horizons. The first class includes only the already known solutions that exist for a few special values of the dilaton coupling constant. Solutions belonging to the second class have essentially different properties. They exist for continuously varying values of the dilaton coupling constant, but arise only for discrete values of the dilaton field at the horizon. For each given value of the dilaton coupling constant, there may exist several such solutions differing by the number of zeros of the shifted dilaton function in the subhorizon region and separating the domains of singular solutions.

On the effect of small-scale oceanic variability on topography-generated currents

description: Small-scale oceanic motions, in combination with bottom topography, induce mean large-scale along-isobaths flows. The direction of these mean flows is usually found to be anticyclonic (cyclonic) over bumps (depressions). Here we employ a quasigeostrophic model to show that the current direction of these topographically induced large-scale flows can be reversed by the small-scale variability. This result addresses the existence of a new bulk effect from the small-scale activity that could have strong consequences on the circulation of the world's ocean.

description: In response to the health crisis, they set up schools on abandoned ferries; classes were held on rooftops and in nearby forests.1 The above quote is not a description of contemporary educational spaces in response to the current COVID-19 pandemic. Rather, this is a description of outdoor learning environments established in response to the early 20th century tuberculosis crisis. At the time, there were 65 such outdoor classrooms established as alternative teaching and learning environments.2 However, once the health crisis subsided, learning returned indoors. This paper will briefly trace the intermittent history of the design and use outdoor classrooms in PK-12 educational settings, including an examination of the nascent but growing movement for contemporary outdoor learning environments, culminating in a case study project focusing on the design and construction of a series of modest outdoor educational installations for a California elementary school, with the aspiration that these spaces might inspire outside teaching and learning. A group of advanced architecture students, with input from the children clients and under the supervision of a faculty advisor who is a licensed architect, transformed a series of empty spaces at a local elementary school into interactive outdoor learning environments. As a design-build exercise, these hands-on projects took these students out of the traditional studio and into an interdisciplinary professional experience. While these case studies were originally inspired to function as spaces for environmental learning, there is a growing interest in outdoor learning environments in order to provide a viable alternative to the current challenges with indoor learning due to the COVID-19 pandemic. Particularly during this pandemic, marginalized students are more likely to be further disadvantaged due to unequal access to online education as well as additional economic and social stressors on top of home confinement, all of which further increases the learning gap.3 Access to outdoor learning environments could provide one answer to the current challenges of accommodating in-person learning. Taking advantage of the restorative and calming potential of the natural environment, outdoor classrooms could provide an alternative pedagogical setting to assist with the return to in-person learning while also providing an opportunity for designers to critically re-examine generic learning environments.

Locus of Feedback Control in Computer-Based Tutoring: Impact on Learning Rate, Achievement and Attitudes
Creators: name: Corbett, Albert T
name: Anderson, John R
Publisher: name: Carnegie Mellon University
Year: 2001
Subjects: Applied Computer Science

description: The advent of second-generation intelligent computer tutors raises an important instructional design question: when should tutorial advice be presented in problem solving? This paper examines four feedback conditions in the ACT Programming Tutor. Three versions offer the student different levels of control over error feedback and correction: (a) immediate feedback and immediate error correction; (b) immediate error flagging and student control of error correction; (c) feedback on demand and student control of error correction. A fourth, No-tutor condition offers no step-by-step problem solving support. The immediate feedback group with greatest tutor control of problem solving yielded the most efficient learning. These students completed the tutor problems fastest, and the three tutorsupported groups performed equivalently on tests. Questionnaires revealed little student preference among the four conditions. These results suggest that students will need explicit guidance to benefit from learning opportunities that arise when they have greater control over tutorial assistance.
