description: We introduce \textcolor{red}{general} new techniques for computing the geometric index of a link $L$ in the interior of a solid torus $T$. These techniques simplify and unify previous ad hoc methods used to compute the geometric index in specific examples \textcolor{red}{ and allow the simple computation of geometric index for new examples where the index was not previously known}. The geometric index measures the minimum number of times any meridional disc of $T$ must intersect $L$. It is related to the algebraic index in the sense that adding up signed intersections of an interior simple closed curve $C$ in $T$ with a meridional disc gives $\pm$ the algebraic index of $C$ in $T$. One key idea is introducing the notion of geometric index for solid chambers of the form $B^2\times I$ in $T$. After that we prove that if a solid torus can be divided into solid chambers by meridional discs in a specific \textcolor{red}{(and often easy to obtain)} way, then the geometric index can be easily computed.

description: The structural, electronic, magnetic and ferroelectric properties of Pb free double perovskite multiferroic Bi2FeTiO6 are investigated using density functional theory within the general gradient approximation (GGA) method. Our structural optimization using total energy calculations for different potential structures show a minimum energy for a non-centrosymmetric rhombohedral structure with R3 space group. Bi2FeTiO6 is found to be an antiferromagnetic insulator with C-type magnetic ordering with bandgap value of 0.3 eV. The calculated magnetic moment of 3.52 μ_B at Fe site shows the high spin arrangement of 3d electrons which is also confirmed by our orbital projected density of states analysis. We have analyzed the characteristics of bonding present between the constituents of Bi2FeTiO6 with the help of calculated partial density of states and Born effective charges. The ground state of the nearest centrosymmetric structure is found to be a G-type antiferromagnet with half metallicity showing that by the application of external electric field we can not only get a polarized state but also change the magnetic ordering and electronic structure in the present compound indicating strong magnetoelectric coupling. The cation sites the coexistence of Bi 6s lone pair (bring disproportionate charge distribution) and Ti4+ d0 ions which brings covalency produces off-center displacement and favors a non-centrosymmetric ground state and thus ferroelectricity. Our Berry phase calculation gives a polarization of 48 \muCcm-2 for Bi2FeTiO6.

description: For many years, the HCI community has harbored a vision of interacting with intelligent, embodied computer agents. However, the reality of this vision remains elusive. From an interaction design perspective, little is known about how to specifically design an embodied agent to support the task it will perform and the social interactions that will result. This paper presents design research that explores the relationship between the visual features of embodied agents and the tasks they perform, and the social attributions that result. Our results show a clear link between agent task and agent form and reveals that people often prefer agents who conform to gender stereotypes associated with tasks. Based on the results of this work, we provide a set of emerging design considerations to help guide interaction designers in creating the visual form of embodied agents.

description: The validity of the widely used linear mixing approximation for the equations of state (EOS) of planetary ices is investigated at pressure-temperature conditions typical for the interior of Uranus and Neptune. The basis of this study are ab initio data ranging up to 1000 GPa and 20 000 K calculated via density functional theory molecular dynamics simulations. In particular, we calculate a new EOS for methane and EOS data for the 1:1 binary mixtures of methane, ammonia, and water, as well as their 2:1:4 ternary mixture. Additionally, the self-diffusion coefficients in the ternary mixture are calculated along three different Uranus interior profiles and compared to the values of the pure compounds. We find that deviations of the linear mixing approximation from the results of the real mixture are generally small; for the thermal EOS they amount to 4% or less. The diffusion coefficients in the mixture agree with those of the pure compounds within 20% or better. Finally, a new adiabatic model of Uranus with an inner layer of almost pure ices is developed. The model is consistent with the gravity field data and results in a rather cold interior ($\mathrm{T_{core}} \mathtt{\sim}$ 4000 K).

description: We present a numerical study of type IIB supergravity solutions with varying Ramond-Ramond flux. We construct solutions that have a regular horizon and contain nontrivial five- and three-form fluxes. These solutions are holographically dual to the deconfined phase of confining field theories at finite temperature. As a calibration of the numerical method we first numerically reproduce various analytically known solutions including singular and regular nonextremal D3 branes, the Klebanov-Tseytlin solution and its singular nonextremal generalization. The horizon of the solutions we construct is of the precise form of nonextremal D3 branes. In the asymptotic region far away from the horizon we observe a logarithmic behavior similar to that of the Klebanov-Tseytlin solution.

description: Al cabo de siglos de teología y racionalismo, el siglo XIX quiere levantar un orden de valores dentro del cual el hombre pueda construir un yo que se arrogue el protagonismo de su propia vida. La formulación estética de ese yo halla en el arte romántico su vehículo y forma. En Hispanoamérica el mayor interés del romanticismo es la elaboración de un sistema simbólico que cohesione los valores, aún dispersos, de las nuevas naciones americanas. Para ello, el arte recurre a la descripción de la naturaleza; la poesía de amor, lo nacional en contraste con lo exótico. Todo ello desde la celebración de una individualidad que proclama su diferencia en relación a otro —ya sea la naturaleza, el indio o la mujer— para tomar posición frente al mundo y plantear su conexión con lo trascendente. Todas estas preocupaciones son caras al romanticismo, le sirven para pensar, desde distintos ángulos, su centro temático: la formulación de un yo. “¿Quién que Es, no es romántico?”, interrogaba, retóricamente, Rubén Darío. Su pregunta señala el innegable afán protagónico del yo romántico que el modernismo y otros movimientos posteriores heredarán.

description: Cet article examine l’avenir électronique de la gestion des ressources humaines, en insistant sur l’importance de la digitalisation ou la numérisation de l’administration en général et de la gestion des ressources humaines en particulier afin d’actualiser ses pratiques, surtout à la lumière de l’évolution de la situation environnementale, et le meilleur exemple de cette dernière est la crise épidémique actuelle qui touche le monde dans son ensemble, à savoir « le covid 19 ».

L’étude a révélé que la digitalisation ou la numérisation de la gestion des ressources humaines devrait être considérée comme une nécessité urgente pour améliorer son efficacité en tant que fonction stratégique et actualiser sa pratique, ainsi que ses effets positifs sur les aspects économiques, sociaux et environnementaux. C’est aussi une stratégie et une approche moderne pour faire face aux crises, en particulier celles qui s’imposent dans leurs phases de distanciation et de non-respect du lieu de travail. Enfin, cette dernière nous montre que les pratiques en matière de ressources humaines doivent être reconsidérées et qu’une plus grande attention doit être accordée au facteur humain dans tous les aspects.

description: The composition and morphology of the interstellar medium in starburst galaxies has been well investigated, but the magnetic field properties are still uncertain. The nearby starburst galaxy M82 provides a unique opportunity to investigate the mechanisms leading to the amplification and reduction of turbulent and regular magnetic fields. Possible scenarios of the contribution of the magnetic field to the star-formation rate are evaluated. Archival data from the VLA and WSRT were combined and re-reduced to cover the wavelength regime between 3cm and 22cm. All observations revealed polarised emission in the inner part of the galaxy, while extended polarised emission up to a distance of 2kpc from the disk was only detected at 18cm and 22cm. The observations hint at a magnetised bar in the inner part of the galaxy. We calculate the mass inflow rate due to magnetic stress of the bar to 7.1 solar masses per year, which can be a significant contribution to the star-formation rate of M82 of approximately 13 solar masses per year. The halo shows polarised emission, which might be the remnant of a regular disk field. Indications for a helical field in the inner part of the outflow cone are provided. The coherence length of the magnetic field in the centre is similar to the size of giant molecular clouds. Using polarisation spectra more evidence for a close coupling of the ionised gas and the magnetic field as well as a two-phase magnetic field topology were found. Electron densities in the halo are similar to the ones found in the Milky Way. The magnetic field morphology is similar to the one in other nearby starburst galaxies with possible large-scale magnetic loops in the halo and a helical magnetic field inside the outflow cones. The special combination of a magnetic bar and a circumnuclear ring are able to significantly raise the star-formation rate in this galaxy by magnetic braking.

description: The isotope effect in the scattering of methane is studied by wavepacket simulations of oriented CH4 and CD4 molecules from a flat surface including all nine internal vibrations. At a translational energy up to 96 kJ/mol we find that the scattering is still predominantly elastic, but less so for CD4. Energy distribution analysis of the kinetic energy per mode and the potential energy surface terms, when the molecule hits the surface, are used in combination with vibrational excitations and the corresponding deformation. They indicate that the orientation with three bonds pointing towards the surface is mostly responsible for the isotope effect in the methane dissociation.

Examples are transport of charge carriers in semiconductors and phase separation processes in alloys.

description: We calculate the recombination spectra of the He-like ions He~I, C~V, N~VI, O~VII, Ne~IX, Mg~XI, Si~XIII, S~XV, Ar~XVII, Ca~XIX, and Fe~XXV. We include the following physical processes: radiative recombination, dielectronic recombination, three-body recombination, electron impact ionization, and collisional excitation by electrons, protons, and $α$-particles. The calculations account for the effects of lowering of the continuum at high densities and high density corrections to dielectronic recombination. Then we construct models for He-like ions for fast computation of their spectra. Every model includes 29 bound levels up to n=5 and 6 doubly excited levels that account for the most important satellite lines. The models are constructed in a way that allows for proper approach to LTE under appropriate conditions. These models can simultaneously solve for the H/He-like ionization balance in photoionized or collisionally ionized plasmas and compute emission spectra including the combined effects of radiative and dielectronic recombination, collisional excitation, photoionization from excited levels, fluorescence, and line trapping. The models can be used for any temperature between 100 and $10^9$K and electron densities of up to $10^{18}$ \cm3. The models can be easily used within spectral modeling codes or as stand-alone tools for spectral analysis. We present comparisons between the results of the present models and previous work. Significant differences are found between the present effective recombination rate coefficients to the $n=2$ and those of previous estimates. Later, we study various emission line ratio diagnostics under collisional ionization and photoionized conditions.

description: We report a study of the geometrically frustrated magnetic material Tb2Sn2O7 by the positive muon spin relaxation technique. No signature of a static magnetically ordered state is detected while neutron magnetic reflections are observed in agreement with a published report. This is explained by the dynamical nature of the ground state of Tb2Sn2O7: the Tb3+ magnetic moment characteristic fluctuation time is ~ 10^{-10} s. The strong effect of the magnetic field on the muon spin-lattice relaxation rate at low fields indicates a large field-induced increase of the magnetic density of states of the collective excitations at low energy.

Double plasma resonance instability as a source of solar zebra emission

description: The double plasma resonance (DPR) instability plays a basic role in the generation of solar radio zebras. In the plasma, consisting of the loss-cone type distribution of hot electrons and much denser and colder background plasma, this instability generates the upper-hybrid waves, which are then transformed into the electromagnetic waves and observed as radio zebras. In the present paper we numerically study the double plasma resonance instability from the point of view of the zebra interpretation. We use a 3-dimensional electromagnetic particle-in-cell (3-D PIC) relativistic model. First using the multi-mode model, we study details of the double plasma resonance instability. We show how the distribution function of hot electrons changes during this instability. Then we show that there is a very good agreement between results obtained by the multi-mode and specific-mode models, which is caused by a dominance of the wave with the maximal growth rate. Therefore, for computations in a broad range of model parameters, we use the specific-mode model. We compute the maximal growth rates of the double plasma resonance instability. The results are compared with the analytical ones. We find a very good agreement between numerical and analytical growth rates. We also compute saturation energies of the upper-hybrid waves in a very broad range of parameters. We find that the saturation energies of the upper-hybrid waves show maxima and minima at almost the same values of $ω_\mathrm{UH}/ω_\mathrm{ce}$ as the growth rates. Furthermore, we find that the saturation energy of the upper-hybrid waves is proportional to the density of hot electrons. The maximum saturated energy can be up to one percent of the kinetic energy of hot electrons. All these findings can be used in the interpretation of solar radio zebras.

We consider this idea in application to the family of eigenvalue matrix models: their M-theory unifies various branches of Hermitean matrix model (including Dijkgraaf-Vafa partition functions) with Kontsevich tau-function. Moreover, the corresponding duality relations look like direct analogues of instanton and meron decompositions, familiar from Yang-Mills theory.

description: Case-based reasoning systems need to know the limitations of their expertise. Having found the known source cases most relevant to a target problem, they must assess whether those cases are similar enough to the problem to warrant venturing advice. In experimenting with SIROCCO, a twostage case-based retrieval program that uses structural mapping to analyze and provide advice on engineering ethics cases, we concluded that it would sometimes be better for the program to admit that it lacks the knowledge to suggest relevant codes and past source cases. We identified and encoded three strategic metarules to help it decide. The metarules leverage incrementally deeper knowledge about SIROCCO's matching algorithm to help the program "know what it knows." Experiments demonstrate that the metarules can improve the program's overall advice-giving performance.

description: The body of research on (III,Mn)V diluted magnetic semiconductors initiated during the 1990's has concentrated on three major fronts: i) the microscopic origins and fundamental physics of the ferromagnetism that occurs in these systems, ii) the materials science of growth and defects and iii) the development of spintronic devices with new functionalities. This article reviews the current status of the field, concentrating on the first two, more mature research directions. From the fundamental point of view, (Ga,Mn)As and several other (III,Mn)V DMSs are now regarded as textbook examples of a rare class of robust ferromagnets with dilute magnetic moments coupled by delocalized charge carriers. Both local moments and itinerant holes are provided by Mn, which makes the systems particularly favorable for realizing this unusual ordered state. Advances in growth and post-growth treatment techniques have played a central role in the field, often pushing the limits of dilute Mn moment densities and the uniformity and purity of materials far beyond those allowed by equilibrium thermodynamics. In (III,Mn)V compounds, material quality and magnetic properties are intimately connected. In the review we focus on the theoretical understanding of the origins of ferromagnetism and basic structural, magnetic, magneto-transport, and magneto-optical characteristics of simple (III,Mn)V epilayers, with the main emphasis on (Ga,Mn)As. The conclusions we arrive at are based on an extensive literature covering results of complementary ab initio and effective Hamiltonian computational techniques, and on comparisons between theory and experiment.

description: The aim of this appraisal is to critically reflect upon the published articles and explore ways in which education in sport for development should be designed, delivered, and analysed. In response to this position, I reflect on my personal and professional experiences in sport for development and education and the political and philosophical perspectives that have informed my research. The reflections will explore the influence of these experiences and perspectives on the geographical, social, cultural, and political complexities within the published articles. Through a critical and reflective appraisal, the published articles are synthesised into a coherent body of knowledge. The reflection is framed through the generation of four themes. These are (1) participant engagement and outcomes (2) addressing inequity (3) inclusion for social justice and (4) transformational pedagogy. The critical and reflective appraisal informs a concise summary that outlines the published articles contribution, reflects on what I have learned throughout the process and explores how that knowledge could be applied in the future in the design, delivery and analysis of education within sport for development projects.
Quantum phases of a spin-1 ultracold Bose gas with three body interactions

description: We study the effects of both a repulsive and an attractive three body interaction potential on a spin-1 ultracold Bose gas using mean field approach (MFA). For an antiferromagnetic (AF) inter- action, we have found the existence of the odd-even asymmetry in the Mott insulating (MI) lobes in presence of both the repulsive two and three body interactions. In case of a purely three body repulsive interaction, the higher order MI lobes stabilize against the superfluid phase. However, the spin nematic (singlet) formation is restricted upto the first (second) MI lobes for the former one, while there is neither any asymmetry nor spin nematic (singlet) formation is observed for the later case. The results are confirmed after carefully scrutinizing the spin eigen value and spin nematic order parameter for both the cases. On the other hand, for an attractive three body interaction, the third MI lobe is predominantly affected, where it completely engulfs the second and the fourth MI lobes at large values of the interaction strength. Albeit no significant change is observed beyond the fourth MI lobe. In the ferromagnetic case, the phase diagram shows similar features as that of a scalar Bose gas. We have compared our results on the MFA phase diagrams for both types of the interaction potential via a perturbation expansion in both the cases.

Stellar density distribution along the minor axis of the Large Magellanic Cloud

description: We studied the spatial distribution of young and old stellar populations along the western half part of the minor axis of the Large Magellanic Cloud (LMC) using Washington MT1 photometry of selected fields, which span a deprojected distance range from the LMC bar centre out to ~ 31.6 kpc. We found that both stellar populations share a mean LMC limiting radius of 8.9+-0.4 kpc; old populations are three times more dense that young populations at that LMC limit. When comparing this result with recent values for the LMC extension due to north, the old populations resulted significantly more elongated than the young ones. Bearing in mind previous claims that the elongation of the outermost LMC regions may be due to the tidal effects of the Milky Way (MW), our findings suggest that such a tidal interaction should not have taken place recently. The existence of young populations in the outermost western regions also supports previous results about ram pressure stripping effects of the LMC gaseous disc due to the motion of the LMC in the MW halo.

HCI Cannot Be Used to Evaluate Art
Creators: name: Paulos, Eric
Publisher: name: Carnegie Mellon University
Year: 2007
Subjects: Applied Computer Science

description: While my interests are genuine and resonate strongly with the theme of this workshop, I will take an adversarial approach to the evaluation of art. I do this not to simply be oppositional but to promote the direct discussion of art and debate the appropriateness of its evaluation by computer scientists, designers, and the like.
Sim(2) and SUSY

description: The proposal of hep-ph/0601236, that the laws of physics in flat spacetime need be invariant only under a SIM(2) subgroup of the Lorentz group, is extended to include supersymmetry. $\mathcal{N}=1$ SUSY gauge theories which include SIM(2) couplings for the fermions in chiral multiplets are formulated. These theories contain two conserved supercharges rather than the usual four.

description: We develop off-shell formulations for ${\cal N}=1$ and ${\cal N}=2$ anti-de Sitter supergravity theories in three spacetime dimensions that contain gauge two-forms in the auxiliary field sector. These formulations are shown to allow consistent couplings of supergravity to the Green-Schwarz superstring with ${\cal N}=1$ or ${\cal N}=2$ spacetime supersymmetry. In addition to being $κ$-symmetric, the Green-Schwarz superstring actions constructed are also invariant under super-Weyl transformations of the target space. We also present a detailed study of models for spontaneously broken local supersymmetry in three dimensions obtained by coupling the known off-shell ${\cal N}=1$ and ${\cal N}=2$ supergravity theories to nilpotent Goldstino superfields.

Harnessing the Wisdom of Crowds in Wikipedia: Quality through Coordination
Creators: name: Aniket  Kittur
name: Kraut, Robert E.
Publisher: name: Carnegie Mellon University
Year: 2008
Subjects: Applied Computer Science

description: Wikipedia’s success is often attributed to involving large numbers of contributors who improve the accuracy, completeness and clarity of articles while reducing bias. However, because of the high coordination needed to collaboratively write an article, increasing the number of contributors is costly. We examined how the number of editors in Wikipedia and the coordination methods they use affect article quality. We distinguish between explicit coordination, in which editors plan the article through communication, and implicit coordination, in which a subset of editors set direction by doing the majority of the work. Adding more editors to an article improved article quality only when they used appropriate coordination techniques and was harmful when they did not. Implicit coordination through concentrating the work was more helpful when many editors contributed, but explicit coordination through communication was not. Both types of coordination improved quality more when an article was in a formative stage. These results demonstrate the critical importance of coordination in effectively harnessing the “wisdom of the crowd” in online production environments.
Bond breaking in vibrationally excited methane on transition metal catalysts

description: The role of vibrational excitation of a single mode in the scattering of methane is studied by wave packet simulations of oriented CH4 and CD4 molecules from a flat surface. All nine internal vibrations are included. In the translational energy range from 32 up to 128 kJ/mol we find that initial vibrational excitations enhance the transfer of translational energy towards vibrational energy and increase the accessibility of the entrance channel for dissociation. Our simulations predict that initial vibrational excitations of the asymmetrical stretch (nu_3) and especially the symmetrical stretch (nu_1) modes will give the highest enhancement of the dissociation probability of methane.

Essentials of k-essence

description: We recently introduced the concept of "k-essence" as a dynamical solution for explaining naturally why the universe has entered an epoch of accelerated expansion at a late stage of its evolution. The solution avoids fine-tuning of parameters and anthropic arguments. Instead, k-essence is based on the idea of a dynamical attractor solution which causes it to act as a cosmological constant only at the onset of matter-domination. Consequently, k-essence overtakes the matter density and induces cosmic acceleration at about the present epoch. In this paper, we present the basic theory of k-essence and dynamical attractors based on evolving scalar fields with non-linear kinetic energy terms in the action. We present guidelines for constructing concrete examples and show that there are two classes of solutions, one in which cosmic acceleration continues forever and one in which the acceleration has finite duration.

Creators: name: Rouhi, Leyla
name: Cassiday, Julie A.
Publisher: name: Utah State University
Year: 2019

description: Our epigraph comes from the closing scene of the opening chapter of Leopoldo Alas’s La Regenta (1885). Here Vetusta’s resident erudite, Saturnino Bermúdez, shows the local cathedral to a provincial couple visiting “la heroica ciudad” (I: 135) while he clumsily flirts with Obdulia Fandiño, the town’s most scandalous citizen. This first chapter of La Regenta famously begins with all of Vetusta taking its daily siesta while it “descansaba oyendo entre sueños” (I: 136), as Fermín de Pas, canon theologian and vicar general, ascends the cathedral bell tower to survey his drowsing domain. The multiple symbolic functions of Vetusta’s geography have received ample analysis in the rich scholarship on La Regenta (Turner; Oleza “Introducción”; Nuñez Puente; Nanfito; Iglesias Villamel; Gilfoil; y Vieira). Space indeed serves to organize La Regentain metaphorical and narratological ways, but it also demonstrates the novel’s engagement with processes of the unconscious. As we first meet Vetusta in a state of somnolence and then survey the city, we encounter three linked notions, which previous scholars have not connected: the city’s semi-conscious state, its subterranean depths, and the erasure of the inscriptions within these depths. Obscurity, illegibility, erasure, and an unwillingness to illuminate the hidden recesses of the city’s most important monument give the “cripta cavada” (I: 181) profound psychic resonance. Obdulia and Saturnino’s flirtation there, which arouses without satisfying, links this underground space to the repressed sexual desire with which all Vetusta seethes.
Triangulated categories with cluster-tilting subcategories

description: Let $\C$ be a triangulated category with a cluster tilting subcategory $\T$. We introduce the notion of $\T[1]$-cluster tilting subcategories (also called ghost cluster tilting subcategories) of $\C$, which are a generalization of cluster tilting subcategories. We first develop a basic theory on ghost cluster tilting subcategories. Secondly, we study links between ghost cluster tilting theory and $τ$-tilting theory: Inspired by the work of Iyama, Jørgensen and Yang \cite{ijy}, we introduce the notion of $τ$-tilting subcategories and tilting subcategories of $\mod\T$. We show that there exists a bijection between weak $\T[1]$-cluster tilting subcategories of $\C$ and support $τ$-tilting subcategories of $\mod\T$. Moreover, we figure out the subcategories of $\mod\T$ which correspond to cluster tilting subcategories of $\C$. This generalizes and improves several results by Adachi-Iyama-Reiten \cite{AIR}, Beligiannis \cite{Be2}, and Yang-Zhu \cite{YZ}. Finally, we prove that the definition of ghost cluster tilting objects is equivalent to the definition of relative cluster tilting objects introduced by the first and the third author in \cite{YZ}.

Filling-driven Mott transition in SU(N) Hubbard models

description: We study the filling-driven Mott transition involving the metallic and paramagnetic insulating phases in SU(N) Fermi-Hubbard models, using dynamical mean-field theory (DMFT) and the numerical renormalization group (NRG) as impurity solver. The compressibility shows a striking temperature dependence: near the critical temperature, it is strongly enhanced in the metallic phase close to the insulating phase. We demonstrate that this compressibility enhancement is associated with the thermal suppression of the quasiparticle peak in the local spectral functions. We also explain that the asymmetric shape of the quasiparticle peak originates from the asymmetry in the underlying doublon-holon dynamics.

description: Heterogeneous groups are valuable, but differences among members can weaken group identification. Weak group identification may be especially problematic in larger groups, which, in contrast with smaller groups, require more attention to motivating members and coordinating their tasks. We hypothesized that as groups increase in size, productivity would decrease with greater heterogeneity. We studied the longitudinal productivity of 549 research groups varying in disciplinary heterogeneity, institutional heterogeneity, and size. We examined their publication and citation productivity before their projects started and 5 to 9 years later. Larger groups were more productive than smaller groups, but their marginal productivity declined as their heterogeneity increased, either because their members belonged to more disciplines or to more institutions. These results provide evidence that group heterogeneity moderates the effects of group size, and they suggest that desirable diversity in groups may be better leveraged in smaller, more cohesive units.
