description: We review the essentials of the formalism of quantum mechanics based on a deformed Heisenbeg algebra, leading to the existence of a minimal length scale. We compute in this context, the energy spectra of the pseudoharmonic oscillator and Kratzer potentials by using a perturbative approach. We derive the molecular constants, which characterize the vibration--rotation energy levels of diatomic molecules, and investigate the effect of the minimal length on each of these parameters for both potentials. We confront our result to experimental data for the hydrogen molecule to estimate an order of magnitude of this fundamental scale in molecular physics.

Resolving the Structure of Cold Dark Matter Halos II

description: We study the effects of mass and force resolution on the density profiles of galaxy-size Cold Dark Matter (CDM) halos in a flat, low-density cosmological model with vacuum energy. We show thatalthough increasing the mass and force resolution allows us to probe deeper into the inner halo regions, it does not lead to steeper inner density profiles. Instead, the halo profiles converge at scales larger than four times the formal resolution or the radius containing more than 200 particles, whichever is larger. In the simulations presented in this paper, we are able to probe density profile of a relaxed isolated galaxy-size halo at scales r=(0.005-1)r_vir. We find that the density distribution can be well approximated by the profile suggested by Moore etal (1998): rho= x^{-1.5}(1+x^{1.5})^-1, where x=r/r_s and r_s is the characteristic radius. The analytical profile proposed by Navarro et al. (1996) rho= x^{-1}(1+x)^-2, also provides a good fit, with the same relative errors of about 10% for radii larger than 1% of the virial radius. Both analytical profiles fit equally well because for high-concentration galaxy-size halos the differences between these profiles become significant only at scales well below 0.01r_vir. We also find that halos of similar mass may have somewhat different parameters (characteristic radius, maximum rotation velocity, etc.) and shapes of their density profiles. We associate this scatter in properties with differences in halo merger histories and the amount of substructure present in the analyzed halos.

description: We present the iterative design of Momento, a tool that provides integrated support for situated evaluation of ubiquitous computing applications. We derived requirements for Momento from a user-centered design process that included interviews, observations and field studies of early versions of the tool. Motivated by our findings, Momento supports remote testing of ubicomp applications, helps with participant adoption and retention by minimizing the need for new hardware, and supports mid-to-long term studies to address infrequently occurring data. Also, Momento can gather log data, experience sampling, diary, and other qualitative data.

description: Emerging technologies, including artificial intelligence (AI), robotics, digital fabrication, spatial computing, and immersive media such as Augmented Reality (AR) and Virtual Reality (VR), are changing the employment landscape across a broad range of industries. It is anticipated that these technologies will enhance research and innovation, increase productivity, and spur new types of occupations and entrepreneurship. In the architecture, engineering, and construction (AEC) fields, automated building design with advanced software facilitating mass customization will change how buildings are designed. Robotics and automation, particularly in prefabrication and large-scale 3D printing of buildings is expected to change how buildings are built. Automation technology will also transform how work is managed and conducted in the AEC sector. Therefore, it is imperative to prepare students for future changes brought by automation. The Robotics Academy project is a cloud-based training platform designed to support AEC students in learning industrial robotics. This platform uses advances in cloud computing, VR, and learning games to create a personalized and engaging experience for developing programming and robotics operations skills. The Robotics Academy's immersive learning environment aims to offer a solution for teaching robotics in a safe simulated workspace that delivers creative training while minimizing risk. This virtual modality also allows the students to acquire knowledge remotely and without relying on accessing a robotics lab. This paper outlines the process of designing the Robotics Academy's pedagogical approach, its curriculum development, and its delivery method as a VR application. The paper will also describe plans for its future development as a fully customizable and immersive learning game for training students for future jobs in industrial robotics.

description: In recent years, simulations have proven to be an important means to verify the behavior of complex software systems. The different states of a system are monitored in the simulations and are compared against the requirements specification. So far, system states in natural language requirements cannot be automatically linked to signals from the simulation. However, the manual mapping between requirements and simulation is a time-consuming task. Named-entity Recognition is a sub-task from the field of automated information retrieval and is used to classify parts of natural language texts into categories. In this paper, we use a self-trained Named-entity Recognition model with Bidirectional LSTMs and CNNs to extract states from requirements specifications. We present an almost entirely automated approach and an iterative semi-automated approach to train our model. The automated and iterative approach are compared and discussed with respect to the usual manual extraction. We show that the manual extraction of states in 2,000 requirements takes nine hours. Our automated approach achieves an F1-score of 0.51 with 15 minutes of manual work and the iterative approach achieves an F1-score of 0.62 with 100 minutes of work.

Modeling Users’ Mobile App Privacy Preferences: Restoring Usability in a Sea of Permission Settings

description: In this paper, we investigate the feasibility of identifying a small set of privacy profiles as a way of helping users manage their mobile app privacy preferences. Our analysis does not limit itself to looking at permissions people feel comfortable granting to an app. Instead it relies on static code analysis to determine the purpose for which an app requests each of its permissions, distinguishing for instance between apps relying on particular permissions to deliver their core functionality and apps requesting these permissions to share information with advertising networks or social networks. Using privacy preferences that reflect people’s comfort with the purpose for which different apps request their permissions, we use clustering techniques to identify privacy profiles. A major contribution of this work is to show that, while people’s mobile app privacy preferences are diverse, it is possible to identify a small number of privacy profiles that collectively do a good job at capturing these diverse preferences.
Modeling the Impact of Shared Visual Information on Collaborative Reference

Subjects: Applied Computer Science

description: A number of recent studies have demonstrated that groups benefit considerably from access to shared visual information. This is due, in part, to the communicative efficiencies provided by the shared visual context. However, a large gap exists between our current theoretical understanding and our existing models. We address this gap by developing a computational model that integrates linguistic cues with visual cues in a way that effectively models reference during tightly-coupled, task-oriented interactions. The results demonstrate that an integrated model significantly outperforms existing language-only and visual-only models. The findings can be used to inform and augment the development of conversational agents, applications that dynamically track discourse and collaborative interactions, and dialogue managers for natural language interfaces.
title: Alegoría y revolución. La política de la literatura en El caballero de las botas azules (1867)
Creators: name: do Cebreiro Rábade Villar, María
Publisher: name: Utah State University
Year: 2013

description: La bibliografía crítica sobre El caballero de las botas azules ha venido oscilando entre su consideración como sátira social o su consideración como artefacto metaliterario. Los autores adscritos al primer marco exegético suelen subrayar el propósito políticamente reformista—o en términos más exactos, regenerador—de la fábula literaria de Rosalía de Castro (Davies, Rivera, García Negro, Rodríguez, Miguélez-Carballeira). Por su parte, los autores que defienden la consideración de El caballero de las botas azules como parodia de la literatura española del siglo XIX, inciden en el carácter metaficcional de la trama y en su voluntad de transformar el panorama de la novelística hispánica, dominado por el folletín y otras modalidades de la incipiente literatura de consumo (Risco, Gullón, Miralles, Fernández Rodríguez, Posada Alonso, Rodríguez Yáñez). Esta oposición se ha extendido incluso a aquellos trabajos situados en la órbita de paradigmas teóricos más recientes, como los estudios poscoloniales (Johnson-Hoffman), los estudios feministas (Charnon-Deutsch) o la sociología literaria (Fernández). En cambio, es obvio que a pesar de su polaridad ambas apuestas de lectura comparten al menos dos puntos de partida: el propósito de cambio (sea este político o literario) que actúa como motor de la obra y la ambigüedad semántica que atraviesa la trama.

description: Intelligent tutoring systems help students acquire cognitive skills by tracing students’ knowledge and providing relevant feedback. However, feedback that focuses only on the cognitive level might not be optimal - errors are often the result of inappropriate metacognitive decisions. We have developed two models which detect aspects of student faulty metacognitive behavior: A prescriptive rational model aimed at improving help-seeking behavior, and a descriptive machine-learned model aimed at eliminating attempts to “game” the tutor. In a comparison between the two models we found that while both successfully identify gaming behavior, one is better at characterizing the types of problems students game in, and the other captures a larger variety of faulty behaviors. An analysis of students’ actions in two different tutors suggests that the help-seeking model is domain independent, and that students’ behavior is fairly consistent across classrooms, age groups, domains, and task elements.

description: We have developed a shell model potential to describe PbTiO3 and PbMg1/3Nb2/3O3 (PMN) by fitting to first-principles results. At zero pressure, the model reproduces the temperature behavior of PbTiO3, but with a smaller transition temperature than experimentally observed. We then fit a shell model potential for the complex PMN based on the transferability of the interatomic potentials. We find that even for ordered PMN, quenching the structure gives a non-polar state, but with local polarization (off-center ions) indicative of relaxor behavior.

description: We derive a complete geometrical characterisation of a large class of $AdS_3$, $AdS_4$ and $AdS_5$ supersymmetric spacetimes in eleven-dimensional supergravity using G-structures. These are obtained as special cases of a class of supersymmetric $\mathbb{R}^{1,1}$, $\mathbb{R}^{1,2}$ and $\mathbb{R}^{1,3}$ geometries, naturally associated to M5-branes wrapping calibrated cycles in manifolds with $G_2$, SU(3) or SU(2) holonomy. Specifically, the latter class is defined by requiring that the Killing spinors satisfy the same set of projection conditions as for wrapped probe branes, and that there is no electric flux. We show how the R-symmetries of the dual field theories appear as isometries of the general AdS geometries. We also show how known solutions previously constructed in gauged supergravity satisfy our more general G-structure conditions, demonstrate that our conditions for half-BPS $AdS_5$ geometries are precisely those of Lin, Lunin and Maldacena, and construct some new singular solutions.

description: Fixed Communication Provider (FCP) is a consortium of Internet Service Providers (ISPs) which users can switch easily and freely between their ISPs. In order to increase the QoS of the ISPs, we propose a two class service model as the following. ISPs divide their available bandwidth into two parts to provide their end users with optimal services. One dedicated to primary users, and the other for secondary users. Primary users are those who pay more and thus, expect dedicated bandwidth that is always available. Secondary services are provided by ISPs for the other users who cannot afford the dedicated bandwidth. In this study, by defining the utility functions for both user types, we aim at dividing the ISP bandwidth between these two services such that the utility function of the users is maximized. Since the primary users do not always use the maximum bandwidth, an algorithm is proposed for ISPs to estimate the primary users required bandwidth in each time segment based on the previous segments. Based on this estimate, the expected bandwidth is dedicated to the primary users, and the remaining bandwidth is devoted to the secondary users to improve the Quality of Service (QoS). On the other hand, an ISP is penalized if it fails to provide the primary users with the required bandwidth mentioned in their contract. Therefore, there exists a trade-off between the conservative estimation of the primary users rate, QoS of the secondary users and the achieved utility of the ISPs.

description: Cheaper and more powerful sensors, predictive cognitive CBM system, together with big data analytics, offer an unprecedented opportunity to track machine-tool performance and health condition. However, manufacturers only spend 15% of their total maintenance costs on predictive (vs reactive or preventative) maintenance.
 The PreCoM project will deploy and test a predictive cognitive maintenance decision-support system able to identify and localize damage, assess damage severity, predict damage evolution, assess remaining asset life, reduce the probability of false alarms, provide more accurate failure detection, issue notices to conduct preventive maintenance actions and ultimately increase in-service efficiency of machines by at least 10%.
 The platform includes 4 modules: 1) a data acquisition module leveraging external sensors as well as sensors directly embedded in the machine tool components, 2) an artificial intelligence module combining physical models, statistical models and machine-learning algorithms able to track individual health condition and supporting a large range of assets and dynamic operating conditions, 3) a secure integration module connecting the platform to production planning and maintenance systems via a private cloud and providing additional safety, self-healing and self-learning capabilities and 4) a human interface module including production dashboards and augmented reality interfaces for facilitating maintenance tasks.
 The consortium includes 3 end-user factories, 3 machine-tool suppliers, 1 leading component supplier, 4 innovative SMEs, 3 research organizations and 3 academic institutions. Together, we will validate the platform in a broad spectrum of real-life industrial scenarios (low volume, high volume and continuous manufacturing). We will also demonstrate the direct impact of the platform on maintainability, availability, work safety and costs in order to document the results in detailed business cases for widespread industry dissemination and exploitation.

description: Injecting magnetized plasma with changes in magnetization or injection rate necessitate a time variable magnetic field at the boundary of the simulation box. Naive implementation will lead to electromagnetic precursor waves that can affect the simulation results. The problem is well-known and is described e.g. in Lemebege and Dawson 1987. Since then few papers have attempted to deal with this problem and no standard solution exists. In this research note we suggest that the ad-hoc pulse shape that was used in the paper by Lemebege and Dawson 1987 can be replaces by a standard digital low pass filter. The cut off frequency of this filter should coincide with the gyro frequency in the magnetized plasma, to make use of (Doppler-broadend) resonant absorption caused by gyrating electrons. We illustrate this idea with a code example and demonstrate the efficency of this method throug sample simulations with our electromagnetic particle-in-cell code.

description: Extensive interviews with riders of the Pittsburgh bus system revealed that, as the top priority, riders want to know the current location of buses. Using a universal design methodology, we designed a system, named Tiramisu, to foster a greater sense of community between riders and transit bus service providers. Our design focuses on crowd-sourcing acquisition of information about bus location and fullness, predicting the arrival time of buses, and providing a convenient platform for reporting problems and positive experiences within the transit system. This will create a user community of riders that are participating in the delivery of service. Tiramisu also supports specific information and reporting needs for riders with disabilities, thereby providing greater independent mobility around the community. Early field testing of Tiramisu suggests our approach is both feasible and potentially viable. In summary, Tiramisu is valuable enough for riders to commit time and effort to its use to produce a sustained user community

description: A wavefront solution for quantum (capacitively coupled) transmission lines with charge discreteness (PRB {\bf 64}, 235309 (2001)) is proposed for the first time. The nonlinearity of the system becomes deeply related to charge discreteness. The wavefront velocity is found to depend on a step discontinuity on the (pseudo) flux variable, $f$, displaying allowed and forbidden regions (gaps), as a function of $f$. A preliminary study of the stability of the solutions is presented. The dual transmission line hamiltonian is proposed and finally, we find a connection with the (quantum) Toda lattice.

description: Genus Miotopus Hutton, 1898
Medium size cave wētā (body length 11–17 mm) found in forests and caves, on three main islands of New Zealand. The genus consists of two species that are structurally quite distinct from one another, and share some morphological characteristics with Pleioplectron.
The head of Miotopus tends to be more elongated than in Pleioplectron, coloured mostly brown. Scapes of the antennae are sexually dimorphic, very broad in the males, thinner in the females (Fig. 5). Maxillary palps are long with moderately dense hair. The colour pattern of the upper body parts of the two species is similar, but darker in P. diversus, and surprisingly uniform across the whole distribution range with alternating reddish-brown and black patches. The light-coloured patches form a large inverted W-shape on the pronotum, and an X-shape stretching across the mesanotum, metanotum and first abdominal tergite (Fig. 6).
Legs are relatively long in both species, especially so in the newly described species. Fore and mid femora are armed at the apex with a prolateral and a retrolateral apical spine. Fore and mid tibia armed with two pairs of apical spines each, four pairs on the hind tibia. The number of linear spines on all tibiae varies within and between species (Table 1).
Male and female terminalia are species specific (Figs 7–8); cerci long and slender, especially in the males. The upper valves of the ovipositor are scabrous but not serrated (the irregularities being visible only at high magnification), while the lower valves have 7+ shallow teeth near the apex (Fig. 8).

description: With the widespread adoption of smartphones, mobile applications have gained mainstream popularity. However, the potential privacy and security risks associated with using mobile apps are quite high, as smartphones become increasingly integrated with our lives, being able to access our email, social networking accounts, financial information, personal photos, and even our cars and homes. To address this problem, we introduce AppScanner, an automated cloud-based service based on crowdsourcing and traditional security approaches to analyze mobile applications. Considering the large and growing number of mobile applications, our envisioned service builds on crowdsourcing, virtualization, and automation to enable large-scale analysis of apps. AppScanner provides end-users with more understandable information regarding what mobile apps are really doing on their devices.

description: Mathematical information retrieval is a relatively new area, so the first search tools capable of retrieving mathematical formulas began to appear only a few years ago. The proposals made public so far mostly implement searches on internal university databases, small sets of scientific papers, or Wikipedia in English. As such, only modest computing power is required. In this context, SearchOnMath has emerged as a pioneering tool in that it indexes several different databases and is compatible with several mathematical representation languages. Given the significantly greater number of formulas it handles, a distributed system becomes necessary to support it. The present study is based on the Microsoft BizSpark program and has aimed, for 38 different distributed-system scenarios, to pinpoint the one affording the best response times when searching the SearchOnMath databases for a collection of 120 formulas.

description: Studies of quasar absorption lines reveal that the low density intergalactic medium at z ~ 3 is enriched to 0.001-0.01 solar metallicity. This enrichment may have occurred in an early generation of Population III stars at redshift z >~ 10, by protogalaxies at 6 ~ 3 by galaxies of baryonic mass >~ 10^8.5 solar masses. We use already completed cosmological simulations to which we add a prescription for chemical evolution and metal ejection by winds, assuming that the winds have properties similar to those observed in local starbursts and Lyman-break galaxies. Results are given for a number of representative models, and we also examine the properties of the galaxies responsible for the enrichment as well as the physical effects responsible for wind escape and propagation. We find that winds of velocity >~ 200-300 km/s are capable of enriching the IGM to the mean level observed, though many low-density regions would remain metal free. Calibrated by observations of Lyman-break galaxies, our calculations suggest that most galaxies at z >~ 3 should drive winds that can escape and propagate to large radii. The primary effect limiting the enrichment of low-density IG gas in our scenario is then the travel time from high- to low-density regions, implying that the metallicity of low-density gas is a strong function of redshift.

A Nonthermal Radio Filament Connected to the Galactic Black Hole?

description: Using the Very Large Array, we have investigated a non-thermal radio filament (NTF) recently found very near the Galactic black hole and its radio counterpart, SgrA*. While this NTF -- the Sgr A West Filament (SgrAWF) -- shares many characteristics with the population of NTFs occupying the central few hundred parsecs of the Galaxy, the SgrAWF has the distinction of having an orientation and sky location that suggest an intimate physical connection to SgrA*. We present 3.3 and 5.5 cm images constructed using an innovative methodology that yields a very high dynamic range, providing an unprecedentedly clear picture of the SgrAWF. While the physical association of the SgrAWF with SgrA* is not unambiguous, the images decidedly evoke this interesting possibility. Assuming that the SgrAWF bears a physical relationship to SgrA*, we examine the potential implications. One is that SgrA* is a source of relativistic particles constrained to diffuse along ordered local field lines. The relativistic particles could also be fed into the local field by a collimated outflow from SgrA*, perhaps driven by the Poynting flux accompanying the black hole spin in the presence of a magnetic field threading the event horizon. Second, we consider the possibility that the SgrAWF is the manifestation of a low-mass-density cosmic string that has become anchored to the black hole. The simplest form of these hypotheses would predict that the filament be bi-directional, whereas the SgrAWF is only seen on one side of SgrA*, perhaps because of the dynamics of the local medium.

description: The city has always been a site of cultural, social and physical transformation, on scales from the most personal to the most collective. However, with the rise of the “metapolis” [3, 4] and the issues it brings with it, 24/7 rush hours, the conversion of public space to commercial space, the rise of surveillance, transnational neighborhoods, polyvocal politics and architecture etc. the contemporary city is weighted down. We can no longer technologically or socially be constrained by something planned and canned, like another confectionary spectacle. We dream of something more, something that can respond to our dreams. Something that will transform with us, not just perform change on us, like an operation. The metapolis requires individual, social and technological interaction. As the field of wireless and locative technologies matures, this workshop is interested in exploring a more enduring relationship between the physical and cultural multicity and its digital topographies. This workshop asks the question what might an authentic or native digital/physical relationship be? Authentic to whom? How can these be considered within the hybrid space emerging from the interaction between digital and physical practices? This workshop seek to understand alternative trajectories for digital and wireless technologies while building definitions of place and practice in both physical and digital terms, as well investigating their interaction, influence, disruption, expansion and integration with the social and material practices of our public urban spaces.

description: This paper reflects upon a cross-institutional and multi-level studio collaboration developed in response to the mid-semester closures of Mount Holyoke College and Smith College during the spring 2020 Covid-19 pandemic. Our collaboration was a conscious effort to offer our students an educational opportunity driven by both the students’ and our own desires to meaningfully address the unfolding global pandemic. Within the context of the liberal arts, our focus was to continue to develop the technical capacities of our students, while providing opportunities for vertical collaboration as well as an additional layer of lateral collaboration exposing students to rapid design work occurring in the medical and engineering fields. This paper will focus on the processes of collaboration and methods of engagement enabled by various digital platforms that erased all geographical constraints for collaboration and reflect upon our successes and shortcomings. These methods may be applied to many design studios addressing global issues requiring interdisciplinary and geographically disparate engagement to achieve sustainable design solutions.
Interplay between Josephson effect and magnetic interactions in double quantum dots

description: We analyze the magnetic and transport properties of a double quantum dot coupled to superconducting leads. In addition to the possible phase transition to a $π$ state, already present in the single dot case, this system exhibits a richer magnetic behavior due to the competition between Kondo and inter-dot antiferromagnetic coupling. We obtain results for the Josephson current which may help to understand recent experiments on superconductor-metallofullerene dimer junctions. We show that in such a system the Josephson effect can be used to control its magnetic configuration.

description: We report the electronic band structures and concomitant Fermi surfaces for a family of exfoliable tetradymite compounds with the formula $T_2$$Ch_2$$Pn$, obtained as a modification to the well-known topological insulator binaries Bi$_2$(Se,Te)$_3$ by replacing one chalcogen ($Ch$) with a pnictogen ($Pn$) and Bi with the tetravalent transition metals $T$ $=$ Ti, Zr, or Hf. This imbalances the electron count and results in layered metals characterized by relatively high carrier mobilities and bulk two-dimensional Fermi surfaces whose topography is well-described by first principles calculations. Intriguingly, slab electronic structure calculations predict Dirac-like surface states. In contrast to Bi$_2$Se$_3$, where the surface Dirac bands are at the $Γ-$point, for (Zr,Hf)$_2$Te$_2$(P,As) there are Dirac cones of strong topological character around both the $\bar Γ$- and $\bar {M}$-points which are above and below the Fermi energy, respectively. For Ti$_2$Te$_2$P the surface state is predicted to exist only around the $\bar {M}$-point. In agreement with these predictions, the surface states that are located below the Fermi energy are observed by angle resolved photoemission spectroscopy measurements, revealing that they coexist with the bulk metallic state. Thus, this family of materials provides a foundation upon which to develop novel phenomena that exploit both the bulk and surface states (e.g., topological superconductivity).
Matching Robot Appearance and Behavior to Tasks to Improve Human-Robot Cooperation

description: A robot’s appearance and behavior provide cues to the robot’s abilities and propensities. We hypothesize that an appropriate match between a robot’s social cues and its task will improve people’s acceptance of and cooperation with the robot. In an experiment, people systematically preferred robots for jobs when the robot’s human likeness matched the sociability required in those jobs. In two other experiments, people complied more with a robot whose demeanor matched the seriousness of the task.
