description: We consider solutions of the cosmological equations pertaining to a dissipative, dilaton-driven off-equilibrium Liouville Cosmological model, which may describe the effective field theoretic limit of a non-critical string model of the Universe. The non-criticality may be the result of an early-era catastrophic cosmic event, such as a big-bang, brane-world collision etc. The evolution of the various cosmological parameters of the model are obtained, and the effects of the dilaton and off-shell Liouville terms, including briefly those on relic densities, which distinguish the model from conventional cosmologies, are emphasised.

description: The Cognitive Tutor Authoring Tools (CTAT) support creation of a novel type of tutors called example-tracing tutors. Unlike other types of ITSs (e.g., model-tracing tutors, constraint-based tutors), example-tracing tutors evaluate student behavior by flexibly comparing it against generalized examples of problem-solving behavior. Example-tracing tutors are capable of sophisticated tutoring behaviors; they provide step-by-step guidance on complex problems while recognizing multiple student strategies and (where needed) maintaining multiple interpretations of student behavior. They therefore go well beyond VanLehn’s (2006) minimum criterion for ITS status, namely, that the system has an inner loop (i.e., provides within-problem guidance, not just end-of-problem feedback). Using CTAT, example-tracing tutors can be created without programming. An author creates a tutor interface through drag-and-drop techniques, and then demonstrates the problem-solving behaviors to be tutored. These behaviors are recorded in a “behavior graph,” which can be easily edited and generalized. Compared to other approaches to programming by demonstration for ITS development, CTAT implements a simpler method (no machine learning is used) that is currently more pragmatic and proven for widespread, real-world use by non-programmers. Development time estimates from a large number of real-world ITS projects that have used CTAT suggest that example-tracing tutors reduce development cost by a factor of 4 to 8, compared to “historical” estimates of ITS development time and cost. The main contributions of the work are a novel ITS technology, based on the use of generalized behavioral examples to guide students in problem-solving exercises, as well as a suite of mature and robust tools for efficiently building real-world ITSs without programming.

description: We report results of isothermal magnetotransport and susceptibility measurements at elevated magnetic fields B down to very low temperatures T on high-quality single crystals of the frustrated Kondo-lattice system CePdAl. They reveal a B*(T) line within the paramagnetic part of the phase diagram. This line denotes a thermally broadened 'small'-to-'large' Fermi surface crossover which substantially narrows upon cooling. At B_0* = B*(T=0) = (4.6 +/- 0.1) T, this B*(T) line merges with two other crossover lines, viz. Tp(B) below and T_FL(B) above B_0*. Tp characterizes a frustration-dominated spin-liquid state, while T_FL is the Fermi-liquid temperature associated with the lattice Kondo effect. Non-Fermi-liquid phenomena which are commonly observed near a 'Kondo destruction' quantum critical point cannot be resolved in CePdAl. Our observations reveal a rare case where Kondo coupling, frustration and quantum criticality are closely intertwined.

Creators: name: Sánchez, Santiago Javier
Publisher: name: Utah State University
Year: 2015

description: En este artículo nos proponemos estudiar la transición de la era criolla a la era aluvial en Buenos Aires, tomando como eje las denominadas “sociabilidades” y su vínculo con la identidad de clase.1 Analizaremos así ciertos ámbitos de encuentro de la era criolla, como las tertulias y los antiguos comercios, entre los que se incluirán las tiendas, las pulperías y los cafés, para pasar luego al análisis de las sociabilidades finiseculares. En todos los casos, nuestra fuente principal será la literatura memorialista porteña del Ochenta, pero recurriremos también a otros testimonios contemporáneos. Dentro de la denominada literatura memorialista incluimos a una serie de autores que publicaron memorias, novelas y crónicas históricas durante el período 1880–1910, entre ellos Buenos Aires desde setenta años atrás, de José Antonio Wilde (1881), La gran aldea, de Lucio V. López (1884), Memorias de un viejo, de Vicente Quesada, más conocido por su seudónimo Víctor Gálvez (1889), y Las beldades de mi tiempo, de Santiago Calzadilla (1891). Estos textos vieron la luz en pleno proceso de crecimiento demográfico, inmigración europea masiva y modernización acelerada de una ciudad que, hasta 1880, conservara sus rasgos originales de “Gran Aldea” colonial.2 Los autores memorialistas pertenecieron todos a la elite local más tradicional, aquella que hundía sus raíces en la colonia y reivindicaba su identidad primera frente a la marea cosmopolita que invadía la capital argentina.

description: Since the discovery of the first bona-fide brown dwarfs and extra-solar planets in 1995, the field of low mass stars and substellar objects has considerably progressed, both from theoretical and observational viewpoints.Recent developments in the physics entering the modeling of these objects have led to significant improvements in the theory and to a better understanding of their mechanical and thermal properties. This theory can now be confronted with observations directly in various observational diagrams (color-color, color-magnitude, mass-magnitude, mass-spectral type), a stringent and unavoidable constraint which became possible only recently, with the generation of synthetic spectra. In this paper, we present the current state-of-the-art general theory of low-mass stars and sub-stellar objects, from one solar mass to one Jupiter mass, regarding primarily their interior structure and evolution. This review is a natural complement to the previous review on the atmosphere of low-mass stars and brown dwarfs (Allard et al 1997). Special attention is devoted to the comparison of the theory with various available observations. The contribution of low-mass stellar and sub-stellar objects to the Galactic mass budget is also analysed.

description: Synthetic schlieren is an digital image processing optical method relying on the variation of optical index to visualize the flow of a transparent fluid. In this article, we present a step-by step, easy-to-implement and affordable experimental realization of this technique. The method is applied to air convection caused by a warm surface. We show that the velocity of rising convection plumes can be linked to the temperature of the warm surface and propose a simple physical argument to explain this dependence. Moreover, using this method, one can reveal the tenuous convection plumes rising from ounce's hand, a phenomenon invisible to the naked eye. This spectacular result may help student realize the power of careful data acquisition combined with astute image processing techniques.

Year: 2018

description: Fundada sobre grandes lagos, y alguna vez conocida como la Venecia del Nuevo Mundo, la Ciudad de México siempre ha tenido una relación íntima, pero problemática, con el agua. Al llegar el siglo XIX, uno de los temas más substanciales en las políticas de modernización capitalina fue precisamente el desarrollo y la mejora de las redes de distribución de agua potable a la población. Mientras tanto, a falta de servicio público de abastecimiento, los aguadores cumplían la función de suplir agua a muchos de sus habitantes, llegando a conformar una de las imágenes más reconocibles de las calles de la ciudad, con su gran vasija—el chochocol—cargada en la espalda y otra más pequeña colgando por delante. Esta manera de cargar el agua llamaba la atención por ser específica de México, lo que hizo que el aguador se convirtiera en una figura insistentemente fotografiada, pintada, dibujada y descrita tanto por mexicanos como extranjeros, llegando a convertirse en uno de los representantes simbólicos de la autoctonía cultural mexicana.
Example-Based Generation of Custom Data Analysis Appliances

Year: 2001
Subjects: Applied Computer Science

description: Custom interfaces, which we call appliances, allow users to efficiently carry out specialized tasks. Without one, a user is often required to perform repetitive mechanical steps using general purpose interfaces, which we call tools. Much research has attempted to enable non-programmers to create appliances for themselves. We present a system in which a user can choose an example of the task behavior to be automated from a visualization of his past operations. The example is transformed into a visual language, using two simple rules to generalize from the single example to a class of tasks. The user can then edit this representation directly, or continue to refine the example using selective undo and redo. The visual representation can be transformed into an esthetically pleasing appliance by deleting irrelevant components, and rearranging, resizing, and relabeling other components. Restricting the domain to data analysis tasks enables a well-matched visual query language to be used. Appliance interactions are automatically provided by the underlying interactive visualization system in which the appliance is embedded. An observational study suggests that this system represents a useful point on the ease-of-use vs. expressive power tradeoff appropriate for data analysis, and that the ability to choose and modify examples after the fact is helpful.

description: We briefly discuss the history of suggestions for time- of-flight effects due to non-zero neutrino mass and a recent proposal that such effects can be used to determine the parameters of cosmology. With neutrinos there is potentially a much deeper ``look back time'' than with photons. We note a new point, that if future large scale neutrino detection arrays see long-time secular variations in counting rate, this could be due to highly redshifted bursts originating in the early universe.

Fundamental limits to high-contrast wavefront control

Subjects: subject: Instrumentation and Methods for Astrophysics (astro-ph.IM)

description: The current generation of ground-based coronagraphic instruments uses deformable mirrors to correct for phase errors and to improve contrast levels at small angular separations. Improving these techniques, several space and ground based instruments are currently developed using two deformable mirrors to correct for both phase and amplitude errors. However, as wavefront control techniques improve, more complex telescope pupil geome- tries (support structures, segmentation) will soon be a limiting factor for these next generation coronagraphic instruments. In this paper we discuss fundamental limits associated with wavefront control with deformable mirrors in high contrast coronagraph. We start with an analytic prescription of wavefront errors, along with their wave- length dependence, and propagate them through coronagraph models. We then consider a few wavefront control architectures, number of deformable mirrors and their placement in the optical train of the instrument, and algorithms that can be used to cancel the starlight scattered by these wavefront errors over a finite bandpass. For each configuration we derive the residual contrast as a function of bandwidth and of the properties of the incoming wavefront. This result has consequences when setting the wavefront requirements, along with the wavefront control architecture of future high contrast instrument both from the ground and from space. In particular we show that these limits can severely affect the effective Outer Working Angle that can be achieved by a given coronagraph instrument.

description: Radially inward turbulent particle flux is observed in the core region of target plasma of Large Volume Plasma Device(LVPD). The region satisfy conditions for ETG turbulence, i.e. threshold condition, $ η_e = L_{n_e} / L_{T_e} > 2/3 $ , where density scale length, $ L_{n_e} \sim 300 cm $ and temerature scale length, $ L_{T_e} \sim 50cm $[S.K. Mattoo et al., Phys. Rev. Lett., 108, 255007(2012)\cite{Mattoo_PRL}]. The measured flux is dominantly electrostatic ($Γ_{es} \approx 10^{5} Γ_{em}$) although the nature of the measured turbulence is electromagnetic($β\approx 0.6 $). The turbulence has been established as a consequence of electron temperature gradient (ETG) driven modes. Experimental observations of phase angle between density ($ n_e $) and potential ($ϕ$) fluctuations, $ θ_{\tilde{n}_e, \tildeϕ} $ and electrostatic particle flux, $ Γ_{es} $ shows good agreement with the corresponding theoretical estimates for ETG turbulence.

description: We describe in detail how to implement a coarse-grained hybrid Molecular Dynamics and Stochastic Rotation Dynamics simulation technique that captures the combined effects of Brownian and hydrodynamic forces in colloidal suspensions. The importance of carefully tuning the simulation parameters to correctly resolve the multiple time and length-scales of this problem is emphasized. We systematically analyze how our coarse-graining scheme resolves dimensionless hydrodynamic numbers such as the Reynolds number, the Schmidt number, the Mach number, the Knudsen number, and the Peclet number. The many Brownian and hydrodynamic time-scales can be telescoped together to maximize computational efficiency while still correctly resolving the physically relevant physical processes. We also show how to control a number of numerical artifacts, such as finite size effects and solvent induced attractive depletion interactions. When all these considerations are properly taken into account, the measured colloidal velocity auto-correlation functions and related self diffusion and friction coefficients compare quantitatively with theoretical calculations. By contrast, these calculations demonstrate that, notwithstanding its seductive simplicity, the basic Langevin equation does a remarkably poor job of capturing the decay rate of the velocity auto-correlation function in the colloidal regime, strongly underestimating it at short times and strongly overestimating it at long times. Finally, we discuss in detail how to map the parameters of our method onto physical systems, and from this extract more general lessons that may be relevant for other coarse-graining schemes such as Lattice Boltzmann or Dissipative Particle Dynamics.

description: Sounds such as co-workers chatting nearby or a dripping faucet help us maintain awareness of and respond to our surroundings. Without a tool that communicates ambient sounds in a non-auditory manner, maintaining this awareness is difficult for people who are deaf. We present an iterative investigation of peripheral, visual displays of ambient sounds. Our major contributions are: (1) a rich understanding of what ambient sounds are useful to people who are deaf, (2) a set of visual and functional requirements for a peripheral sound display, based on feedback from people who are deaf, (3) lab-based evaluations investigating the characteristics of four prototypes, and (4) a set of design guidelines for successful ambient audio displays, based on a comparison of four implemented prototypes and user feedback. Our work provides valuable information about the sound awareness needs of the deaf and can help to inform further design of such applications.

description: Previous research has highlighted the advantages of graphical argument representations. A number of tutoring systems have been built that support students in rendering arguments graphically, as they learn argumentation skills.The relative tutoring benefits of graphical argument representations have not been reliably shown, however. In this paper we present an evaluation of the LARGO system which enables law students graphically to represent examples of legal interpretation with hypotheticals they observe while reading texts of U.S. Supreme Court oral arguments. We hypothesized that LARGO’s graphical representations and advice would help students to identify important elements of the arguments (i.e., proposed hypotheses, hypothetical challenges, and responses) and to reflect on their significance to the argument’s merits better than a purely text-based alternative. In an experiment, we found some empirical support for this hypothesis.
title: Identidades de género imaginadas: un análisis de la masculinidad representada en De sobremesa
Creators: name: Valentín Sánchez, Sarah
Publisher: name: Utah State University
Year: 2023

description: La fascinación que despiertan los períodos finiseculares se origina a partir de la vorágine en la que se entremezclan las energías políticas entre lo nuevo y lo obsoleto. En dichos marcos temporales bisagra, pueden mapearse las tendencias conservadoras del discurso cultural del siglo que termina junto con la expresión de las nuevas actitudes modernas, tratando de abrirse camino. Dicho patrón está perfectamente descrito por Elaine Showalter en Sexual Anarchy: Gender and Culture at the Fin de Siècle (1991), en que la autora argumenta que la exploración en las identidades de género y sexual es un continuum que parte de los procesos iniciados a finales del siglo XIX.1 Para Showalter, en los eventos acontecidos a fin de siglo se evidencia una desestabilización en el sistema de género: “all the laws that governed sexual identity and behavior seemed to be breaking down” (3). En dicho contexto, la aparición de nuevos conceptos como la homosexualidad y el feminismo son desencadenantes de procesos múltiples de redefinición de las estructuras afectivo-sexuales. Por un lado, las mujeres toman conciencia de su posición subalterna en la sociedad patriarcal. Entre otros eventos, comienza en este momento la lucha del movimiento feminista por alcanzar la igualdad. Las intelectuales y sufragistas reivindican intensamente el derecho al voto, así como una mayor visibilidad y agencia para las mujeres mediante su incorporación a la esfera pública. Por otra parte, los hombres inician paralelamente su propio cometido de redefinición de la masculinidad, con actitudes disidentes que ponen a prueba los límites de lo normativo. El afianzamiento de la sociedad burguesa conlleva la adopción de un discurso hegemónico que contempla la masculinidad en términos de poder, éxito y productividad en el ámbito industrial.

description: Toroidal quantum states are most promising for building quantum computing and information storage devices as they are insensitive to homogeneous magnetic fields, but interact with charge and spin currents, allowing this moment to be manipulated purely by electrical means. Coupling molecular toroids into larger toroidal moments via ferrotoroidic interactions can be pivotal not only to enhance ground state toroidicity, but also to develop materials displaying ferrotoroidic ordered phases, which sustain linear magneto-electric coupling and multiferroic behaviour. However, engineering ferrotoroidic coupling is known to be a challenging task. Here we have isolated a Cr$^{\mathrm{III}}$Dy$^{\mathrm{III}}_6$ complex, which exhibits the much sought-after ferrotoroidic ground state with an enhanced toroidal moment, solely arising from intramolecular dipolar interactions. Moreover, a theoretical analysis of the observed sub-Kelvin zero-field hysteretic spin dynamics of Cr$^{\mathrm{III}}$Dy$^{\mathrm{III}}_6$ reveals the pivotal role played by ferrotoroidic states in slowing down the magnetic relaxation, in spite of large calculated single-ion quantum tunnelling rates.

description: As one combs through the galley proofs (Galeradas) of Pérez Galdós’s Fortunata y Jacinta, the author’s painstaking linguistic polishing is certainly one element that draws critical attention. But the most eye-catching aspect is, without any doubt, the artwork that adorns many of these typed pages.1 Although there is a degree of subjectivity involved in any such conclusion, one might argue that the more than two dozen sketches of human subjects offer researchers the best example of Galdós’s artistic potential found in either the extant galley proofs or the original manuscripts.2 That said, the goals of this essay are threefold. First, this essay forms part of an ongoing project aimed at publishing as much of Galdós’s manuscript and galley proof artwork as possible so that other critics can take the investigation to another level. Second, we attempt to establish, when possible, connections between the graphic and the lexical, that is to say, a link between the drawings and the characters that appear in Fortunata y Jacinta.

Creators: name: Schnepf, Michael
Publisher: name: Utah State University
Year: 2006

description: In the literary background of Galdós's pivotal 1881 novel, La desheredada, one finds a rich array of references and allusions to authors and their works. Shakespeare's Hamlet and Cervantes's Don Quijote, for instance, share space with lesser-known works such as Faustina Sáez de Melgar's La Cruz del Olivar.1 The present essay analyzes four additional, entirely unstudied literary references found in the original manuscript of La desheredada that provide new insights into how Galdós went about researching and composing the novel that serves as the cornerstone of the Novelas Contemporáneas.

description: Personalised environments such as adaptive educational systems can be evaluated and compared using performance curves. Such summative studies are useful for determining whether or not new modifications enhance or degrade performance. Performance curves also have the potential to be utilised in formative studies that can shape adaptive model design at a much finer level of granularity. We describe the use of learning curves for evaluating personalised educational systems and outline some of the potential pitfalls and how they may be overcome. We then describe three studies in which we demonstrate how learning curves can be used to drive changes in the user model. First, we show how using learning curves for subsets of the domain model can yield insight into the appropriateness of the model’s structure. In the second study we use this method to experiment with model granularity. Finally, we use learning curves to analyse a large volume of user data to explore the feasibility of using them as a reliable method for fine-tuning a system’s model. The results of these experiments demonstrate the successful use of performance curves in formative studies of adaptive educational systems.

description: A complete theoretical model of the nuclear spin conversion in 13CH3F induced by intramolecular ortho-para state mixing is proposed. The model contains parameters determined from the level-crossing spectra of the 13CH3F spin conversion. This set of parameters includes the ortho-para decoherence rate, the magnitude of the hyperfine spin-spin interaction between the molecular nuclei and the energy gap between the mixed ortho and para states. These parameters are found to be in a good agreement with their theoretical estimates.

description: For the first time, based on long-term spectral monitoring with high spectral resolution, the optical spectrum of the weak central star of the IR source RAFGL 5081 has been studied. The spectral type of this star is close to G5-8 II, and its effective temperature is Teff ~5400 K. An unusual spectral phenomenon was discovered: splitting of the profiles of broad, stationary absorption lines of medium and low intensity. The heliocentric radial velocities Vr of all components of metal absorption lines, the NaI D lines, and the H$α$ line were measured for all the observation epochs. The constancy of the absorption lines rules out the possibility that the line splitting is due to binarity. The radial velocities of the wind components in the profiles of the NaI D and H$α$ lines reach $-250$ and $-600$ km/s, respectively. These profiles have narrow components, whose number, depth, and position vary with time. The time variability and multicomponent structure of the profiles of the NaI D and H$α$ lines indicates inhomogeneity and instability of the circumstellar envelope of RAFGL 5081. The presence of components with velocity Vr(IS)=$-65$ km/s in the NaI(1) lines provides evidence that RAFGL 5081 is located behind the Perseus arm, i.e., no closer than 2 kpc. It is noted that RAFGL 5081 is associated with the reflection nebula GN 02.44.7.

description: SimStudent is a machine-learning agent that learns cognitive skills by demonstration. It was originally developed as a building block of the Cognitive Tutor Authoring Tools (CTAT), so that the authors do not have to build a cognitive model by hand, but instead simply demonstrate solutions for SimStudent to automatically generate a cognitive model. The SimStudent technology could then be used to model human students’ performance as well. To evaluate the applicability of SimStudent as a tool for modeling real students, we applied SimStudent to a genuine learning log gathered from classroom experiments with the Algebra I Cognitive Tutor. Such data can be seen as the human students’ “demonstrations” of how to solve problems. The results from an empirical study show that SimStudent can indeed model human students’ performance. After training on 20 problems solved by a group of human students, a cognitive model generated by SimStudent explained 82% of the problem-solving steps performed correctly by another group of human students.

description: The dynamics of a particle in a gravitational quantum well is studied in the context of nonrelativistic quantum mechanics with a particular deformation of a two-dimensional Heisenberg algebra. This deformation yields a new short-distance structure characterized by a finite minimal uncertainty in position measurements, a feature it shares with noncommutative theories. We show that an analytical solution can be found in perturbation and we compare our results to those published recently, where noncommutative geometry at the quantum mechanical level was considered. We find that the perturbations of the gravitational quantum well spectrum in these two approaches have different signatures. We also compare our modified energy spectrum to the results obtained with the GRANIT experiment, where the effects of the Earth's gravitational field on quantum states of ultra cold neutrons moving above a mirror are studied. This comparison leads to an upper bound on the minimal length scale induced by the deformed algebra we use. This upper bound is weaker than the one obtained in the context of the hydrogen atom but could still be useful if the deformation parameter of the Heisenberg algebra is not a universal constant but a quantity that depends on the energetic content of the system.

description: We present the results of a mid-infrared (7 micron) imaging survey of a sample of 24 starless dense cores carried out at an angular resolution of 6 arcsec with the ISOCAM camera aboard the Infrared Space Observatory (ISO). The targeted cores are believed to be pre-stellar in nature and to represent the initial conditions of low-mass, isolated star formation. In previous submillimeter dust continuum studies of such pre-stellar cores, it was found that the derived column density profiles did not follow a single power-law such as N[H2] \propto r^(-1) throughout their full extent but flattened out near their center. These submillimeter observations however could not constrain the density profiles at radii greater than ~ 10000 AU. The present absorption study uses ISOCAM's sensitivity to map these pre-stellar cores in absorption against the diffuse mid-infrared background. The goal was to determine their structure at radii that extend beyond the limits of sensitivity of the submillimeter continuum maps and at twiceas good an angular resolution. Among the 24 cores observed in our survey, a majority of them show deep absorption features. The starless cores studied here all show a column density profile that flattens in the center, which confirms the submillimeter emission results. Moreover, beyond a radius of ~ 5000-10000 AU, the typical column density profile steepens with distance from core center and gets steeper than N[H2] \propto r^(-1), until it eventually merges with the low-density ambient molecular cloud. At least three of the cores present sharp edges at R ~ 15000-30000 AU and appear to be decoupled from their parent clouds, providing finite reservoirs of mass for subsequent star formation.

description: We consider renormalizable couplings of neutral $ϕ$, singly $ϕ^\pm$, and doubly charged $ϕ^{\pm\pm}$ scalar bosons to leptons and the $Z$ gauge boson and calculate the one-loop contributions to the anomalous weak magnetic dipole moment (AWMDM) $a_τ^W$ and the weak electric dipole moment (WEDM) $d_τ^W$ of a charged lepton in a model independent way. The analytic expressions are presented in terms of both parametric integrals and Passarino-Veltman scalar functions. Among the new contributions, there are those arising from the vertices of the type $ϕ^\pm W^\mp Z$ and $Z ϕ_iϕ_j$ ($i\ne j$), along with contributions from doubly charged scalar bosons. Both $a_τ$ and $d_τ^W$ are evaluated in several scenarios , first in a model independent way and then within some popular models, such as two-Higgs doublet models (THDMs), multiple-Higgs doublet models and Higgs triplet models. As far as $a_τ^W$ is concerned, its real part reaches values as high as $10^{-10}-10^{-9}$ for masses of the new scalar bosons in the 200 GeV range, whereas the imaginary part is one or two orders of magnitude below. On the other hand, the most promising scenario for a nonvanishing WEDM is offered by a $CP$-violating THDM in a scenario where the heavy neutral scalar bosons are a mixture of $CP$ eigenstates. It is found that the real part of $d_τ^W$ is of the order of $10^{-24}$ ecm and its imaginary part can reach the $10^{-26}$ ecm level for masses of the new scalar bosons of the order of a few hundred of GeVs. Both the tau AWMDM and WEDM decrease dramatically as the scalar boson masses increase.
