Hidden Role of Maxwell Superalgebras in the Free Differential Algebras of D=4 and D=11 Supergravity
Creators: name: Ravera, L.
Publisher: name: arXiv
Year: 2018
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: The purpose of this paper is to show that the so-called Maxwell superalgebra in four dimensions, which naturally involves the presence of a nilpotent fermionic generator, can be interpreted as a hidden superalgebra underlying N = 1, D=4 supergravity extended to include a 2-form gauge potential associated to a 2-index antisymmetric tensor. In this scenario, the theory is appropriately discussed in the context of Free Differential Algebras (an extension of the Maurer-Cartan equations to involve higher-degree differential forms). The study is then extended to the Free Differential Algebra describing D=11 supergravity, showing that, also in this case, there exists a super-Maxwell algebra underlying the theory. The same extra spinors dual to the nilpotent fermionic generators whose presence is crucial for writing a supersymmetric extension of the Maxwell algebras, both in the D=4 and in the D=11 case, turn out to be fundamental ingredients also to reproduce the D=4 and D=11 Free Differential Algebras on ordinary superspace, whose basis is given by the supervielbein. The analysis of the gauge structure of the supersymmetric Free Differential Algebras is carried on taking into account the gauge transformations from the hidden supergroup-manifold associated with the Maxwell superalgebras.

description: En el ordenamiento jurídico colombiano, si una persona investigada penalmente ejerce, independientemente de la etapa en que se encuentre el proceso, su derecho a guardar silencio y no ofrece explicaciones frente a los hechos por los cuales se le investiga, las autoridades penales no pueden derivar consecuencias negativas en su contra; es decir, el sistema acusatorio colombiano prevé un régimen garantista, debido al reconocimiento constitucional, legal y jurisprudencial de ese derecho. Sin embargo, en la práctica judicial, se presentan situaciones que parecieran relativizar su protección y que acercarían ese modelo al régimen desarrollado por el Tribunal Europeo de Derechos Humanos, en el cual se imponen valoraciones negativas al silencio del acusado, cuando este no ofrece explicaciones lógicas y razonables. Ante este panorama, en el presente trabajo se plantearán, a través del estudio de casos, alternativas que puedan ayudar a solucionar esas problemáticas y a hacer efectivo el régimen constitucional, legal y jurisprudencial del derecho al silencio en la estructura probatoria del sistema acusatorio colombiano.
description: In the Colombian legal system, if an individual who is under criminal investigation exercises their right to remain silent and refrains from offering any explanations regarding the alleged facts under investigation, the penal authorities cannot draw negative consequences against them, regardless the stage of the process. In other words, the Colombian accusatory system provides a protective framework, stemming from the constitutional, legal, and jurisprudential recognition of this right. However, in judicial practice, certain situations arise that appear to undermine this protection and bring the model closer to the one developed by the European Court of Human Rights, wherein negative inferences may be drawn from the accused's silence when logical and reasonable explanations are not provided. Given this context, the present work will propose alternatives, based on the analysis of case studies, to address these issues and effectively uphold the constitutional, legal, and jurisprudential framework concerning the right to silence within the evidentiary structure of the Colombian accusatory system.
Discourse analysis of an organic network: A practice perspective
Creators: name: Baribeau, Julie
Publisher: name: My University
Year: 2017

description: Many organic farmers markets have positioned themselves as an alternative network to the global industrial food system. These markets are now active online in order to promote their activities and products, including the Ottawa Organics Farmer's Market (OOFM), the case for this study. The aim of this research is to provide insights into how organic farmers, as a community of practice, operate discursively online in order to better understand some of the opportunities and limitations they have to influence the greater discourse around food. To do so, we drew on the discourse analysis literature (Nicolini, 2012; Gee, 2011; Alvesson & Karreman, 2000) to gain knowledge into the market’s discursive and representational practices online. Practice theory was specifically mobilized for our discourse analysis. We found out many of the ways that the OOFM constructs and derails the organic food discourses of "organics as technics", "organics as commodity" and "organics as equity".

description: Delivering news to patients and their families can lead to emotionally charged conversations that are difficult for trainees to feel comfortable or effective in. Trisomy 21 (T21), or Down syndrome, is the most common viable chromosomal anomaly. Although prenatal screening exists, over 80% of T21 diagnoses continue to be made postnatally to unsuspecting parents who report a desire for better communication from healthcare professionals when they first receive the news of their child’s diagnosis.16 To better equip trainees to thoughtfully and professionally deliver a diagnosis of T21, we have designed a workshop founded on the principles of Scenario Oriented Learning in Ethics (SOLE) which introduces a framework combining current evidence on communicating life altering news with stated parent preferences. During the workshop, trainees will have the opportunity to practice using the provided communication framework with a standardized patient trained as a new mother. By personally working through a clinical scenario as well as observing workshop colleagues doing the same, participants will gain insight into what is effective as well as ways to troubleshoot encountered pitfalls in a safe and supportive environment. By pre-emptively practicing evidence-based communication, we hope to increase trainee comfort with critical conversations and improve parents’ feelings regarding the quality of communication and support provided while receiving real life T21 diagnoses.

description: We consider a hierarchy of modal event calculi to represent and reason about partially ordered events. These calculi are based on the model of time and change of Kowalski and Sergot's Event Calculus (EC): given a set of event occurrences, EC allows the derivation of the maximal validity intervals (MVIs) over which properties initiated or terminated by those events hold. The formalisms we analyze extend EC with operators from modal logic. They range from the basic Modal Event Calculus (MEC), that computes the set of all current MVIs (MVIs computed by EC) as well as the sets of MVIs that are true in some/every refinement of the current partial ordering of events (Diamond-Box-MVIs), to the Generalized Modal Event Calculus (GMEC), that extends MEC by allowing a free mix of boolean connectives and modal operators. We analyze and compare the expressive power and the complexity of the proposed calculi, focusing on intermediate systems between MEC and GMEC. We motivate the discussion by using a fault diagnosis problem as a case study.
Microwave-optical two-photon excitation of Rydberg states

Subjects: subject: Atomic Physics (physics.atom-ph)

description: We report efficient microwave-optical two photon excitation of Rb Rydberg atoms in a magneto optical trap. This approach allows the excitation of normally inaccessible states and provides a path toward excitation of high angular momentum states. The efficiency stems from the elimination of the Doppler width, the use of a narrow band pulsed laser, and the enormous electric dipole matrix element connecting the intermediate and final states of the transition. The excitation is efficient in spite of the low optical and microwave powers, of order 1 kW and 1 mW, respectively. This is an application of the large dipole coupling strengths between Rydberg states to achieve two photon excitation of Rydberg atoms.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.

Para esto fue necesario diagnosticar la percepción y el nivel de relacionamiento de la marca ciudad con sus principales actores, además de determinar cómo está se ha integrado con las políticas públicas de turismo de modo tal que, pudiesen luego evaluarse sus posibles efectos para la ciudad en su posición competitiva global. Todo esto, a partir de una metodología cualitativa de carácter inductiva, la realización de entrevistas y la revision documental, permitiendo profundizar acerca de sus aspectos teóricos, historia, normatividad y planes de gobierno, sobre lo cual es posible considerar, que su presencia misma genera réditos y beneficios al posicionamiento de la capital.
description: This research analyzes the impact of the city brand in the public management of tourism based on the case study of Bogota from 2012 to 2022. For this purpose, it was necessary to diagnose the perception and the level of relationship of the city brand with its main stakeholders, as well as to determine how it has been integrated with public tourism policies in such a way that its possible effects on the city's global competitive position could then be evaluated. All this, based on a qualitative methodology of inductive character, interviews, and documentary review, allows the deepening of its theoretical aspects, history, regulations, and government plans, on which it is possible to consider that its presence itself generates revenues and benefits to the positioning of the capital.
The Effect of Household Characteristics on the Probability of Homeownership in Canada
Creators: name: Wang, Xinlei
Publisher: name: My University
Year: 2016

description: I study the probability of owning a home for Canadian households and how it is related to the characteristics of households. The characteristics considered include the respondent’s marital status, age, household income before taxes, employment status, the number of vehicles owned, the size of the household and the province of residence. I exploit data from the Survey of Household Spending in 2009. A logit model is estimated to capture the effect of the household characteristics. The main finding is that the probability of owning a home increases as the respondent gets older. A married respondent is more likely to own a home than an unmarried respondent. People with higher incomes are also more likely to own a home. The probability of owning a dwelling increases when vehicles are owned by the household. Province of residence is also an important factor which affects homeownership. However, the respondent’s level of educational attainment and the size of the household do not affect the probability of homeownership.

description: To segregate overlapping objects into depth layers requires the integration of local occlusion cues distributed over the entire image into a global percept. We propose to model this process using hierarchical Markov random field (HMRF), and suggest a broader view that clique potentials in MRF models can be used to encode any local decision rules. A topology-dependent multiscale hierarchy is used to introduce long range interaction. The operations within each level are identical across the hierarchy. The clique parameters that encode the relative importance of these decision rules are estimated using an optimization technique called learning from rehearsals based on 2-object training samples. We find that this model generalizes successfully to 5-object test images, and that depth segregation can be completed within two traversals across the hierarchy. This computational framework therefore provides an in-teresting platform for us to investigate the interaction of local decision rules and global representations, as well as to reason about the rationales underlying some of recent psychological and neurophysiological findings related to figure-ground segregation.

description: We present Tartanian, a game theory-based player for headsup no-limit Texas Hold’em poker. Tartanian is built from three components. First, to deal with the virtually inﬁnite strategy space of no-limit poker, we develop a discretized betting model designed to capture the most important strategic choices in the game. Second, we employ potential-aware automated abstraction algorithms for identifying strategically similar situations in order to decrease the size of the game tree. Third, we develop a new technique for automatically generating the source code of an equilibrium-ﬁnding algorithm from an XML-based description of a game. This automatically generated program is more eﬃcient than what would be possible with a general-purpose equilibrium-ﬁnding program. Finally, we present results from the AAAI-07
Computer Poker Competition, in which Tartanian placed second out of ten entries.
Dipole-like dynamical nuclear spin polarization around a quantum point contact

description: We theoretically investigate the dynamical nuclear spin polarization in a quantum point contact (QPC) at finite magnetic field. We find that when the QPC is tuned to be spin selective, at the conductance of e^2/h, a finite bias induces a dipole-like (spatially anti-symmetric) nuclear polarization: at the QPC center the polarization is zero, while, for GaAs parameters, the nuclear spins down (up) are induced on the source (drain) side. We predict that the dipole-like polarization pattern can be distinguished from a uniform polarization due to a qualitatively different response of the QPC conductance to the NMR field.

title: The role of parasites in host speciation. Testing for parasite-mediated divergent selection at different stages of speciation in cichlid fish
Creators: name: Gobbin, Tiziana Paola
Publisher: name: Universität Bern
Year: 2021
Subjects: subject: 570 Life sciences; biology

description: Parasites represent one of the most successful modes of life in nature and are an important component of ecosystems. By imposing fitness costs on their hosts, parasites constitute a major agent of ecological selection. The host-parasite coevolutionary dynamics of adaptation and counter-adaptation may promote host diversification. The cichlid fish of Lake Victoria have rapidly diversified into hundreds of species, making them a good model system for studying the early stages of speciation.

I investigate whether parasites drive or contribute to host speciation by analysing infection patterns in closely related cichlid populations. I found support for two prerequisites for parasite-mediated selection: host species differed in their infection profiles and these infection differences were maintained over multiple sampling years. Different parasites were located in different microhabitats in the fish gills, also depending on the host species. Since microhabitat segregation constitutes another axis of infection heterogeneity, I suggest to include it in future studies.

Host species variation in infection was not fully explained by exposure to parasites, suggesting that other intrinsic host properties (i.e. immunity) also play a role. Incipient cichlid species reared in aquaria with uniform parasite exposure did not differ in infection, indicating they have not (yet) evolved differences in immunity. This is inconsistent with a role of parasites in driving host divergence. Infection differences accumulate as hosts become more genetically differentiated, but only reproductive isolated host species display a significant difference in infection. This suggests that parasites may contribute to host divergence but they are not initiating it.

description: Biomolecular systems are governed by changes in free energy, and the ability to predict binding free energies provides both better understanding of biomolecular interactions and the ability to optimize them. We present the first graphical-model based approach, which we call GOBLIN (Graphical mOdel for BiomoLecular INteractions), for predicting binding free energies for all-atom models of protein complexes. Our method is physically sound in that internal energies are computed using standard molecular-mechanics force fields, and free energies are obtained by computing a rigorous approximation to the partition function of the system. Moreover, GOBLIN explicitly models both backbone and side-chain flexibility, and, when desired, employs non-linear regression to optimize force-field parameters. In tests on a benchmark set of more than 700 mutants, we show that our method is fast, running in a few minutes, and accurate, achieving root mean square errors (RMSEs) between predicted and experimental binding free energies of 2.05 kcal/mol. GOBLIN’s RMSEs are 0.55 kcal/mol better than the well-known program ROSETTA, despite the fact that we use the ROSETTA force field for computing internal energies. That is, our increase in accuracy is due to our ability to accurately estimate entropic contributions to the free energy. Finally, using our novel algorithm for optimizing force-field parameters on specific protein complexes reduced GOBLIN’s RMSE by 0.26 kcal/mol on average.

description: We are given a set $\mathcal{Z}=\{(R_1,s_1),\ldots, (R_n,s_n)\}$, where each $R_i$ is a \emph{range} in $\Re^d$, such as rectangle or ball, and $s_i \in [0,1]$ denotes its \emph{selectivity}. The goal is to compute a small-size \emph{discrete data distribution} $\mathcal{D}=\{(q_1,w_1),\ldots, (q_m,w_m)\}$, where $q_j\in \Re^d$ and $w_j\in [0,1]$ for each $1\leq j\leq m$, and $\sum_{1\leq j\leq m}w_j= 1$, such that $\mathcal{D}$ is the most \emph{consistent} with $\mathcal{Z}$, i.e., $\mathrm{err}_p(\mathcal{D},\mathcal{Z})=\frac{1}{n}\sum_{i=1}^n\! \lvert{s_i-\sum_{j=1}^m w_j\cdot 1(q_j\in R_i)}\rvert^p$ is minimized. In a database setting, $\mathcal{Z}$ corresponds to a workload of range queries over some table, together with their observed selectivities (i.e., fraction of tuples returned), and $\mathcal{D}$ can be used as compact model for approximating the data distribution within the table without accessing the underlying contents.
 In this paper, we obtain both upper and lower bounds for this problem. In particular, we show that the problem of finding the best data distribution from selectivity queries is $\mathsf{NP}$-complete. On the positive side, we describe a Monte Carlo algorithm that constructs, in time $O((n+δ^{-d})δ^{-2}\mathop{\mathrm{polylog}})$, a discrete distribution $\tilde{\mathcal{D}}$ of size $O(δ^{-2})$, such that $\mathrm{err}_p(\tilde{\mathcal{D}},\mathcal{Z})\leq \min_{\mathcal{D}}\mathrm{err}_p(\mathcal{D},\mathcal{Z})+δ$ (for $p=1,2,\infty$) where the minimum is taken over all discrete distributions. We also establish conditional lower bounds, which strongly indicate the infeasibility of relative approximations as well as removal of the exponential dependency on the dimension for additive approximations. This suggests that significant improvements to our algorithm are unlikely.

description: Over the last few years natural language interfaces (NLI) for databases have gained significant traction both in academia and industry. These systems use very different approaches as described in recent survey papers. However, these systems have not been systematically compared against a set of benchmark questions in order to rigorously evaluate their functionalities and expressive power. In this paper, we give an overview over 24 recently developed NLIs for databases. Each of the systems is evaluated using a curated list of ten sample questions to show their strengths and weaknesses. We categorize the NLIs into four groups based on the methodology they are using: keyword-, pattern-, parsing-, and grammar-based NLI. Overall, we learned that keyword-based systems are enough to answer simple questions. To solve more complex questions involving subqueries, the system needs to apply some sort of parsing to identify structural dependencies. Grammar-based systems are overall the most powerful ones, but are highly dependent on their manually designed rules. In addition to providing a systematic analysis of the major systems, we derive lessons learned that are vital for designing NLIs that can answer a wide range of user questions.

description: Analysis of human motion has great importance for the diagnosis and treatment of motor disorders. Nowadays, several studies in this area use inertial sensors to better understand the behavior caused by motor disorders. As the evaluation performed by clinicians is subjective and susceptible to human errors it is necessary an objective way to measure movements.This paper presents a system composed of Electric Potential Sensors that are able to monitor human movements. The system was evaluated by positioning the hand in the sensor area. A laser pointer was fixed at the middle finger to assist the task execution. Four tasks were employed in order to evaluate the sensor. For differentiation between tasks, a set of features were estimated from filtered signals and then projected onto a 2D space by means of the Sammon's mapping technique. The results showed the different grouping of tasks, demonstrating, thus, the ability to objectively detect and group different movements by the use of a technique, which is entirely passive, through sensing changes in the electric field. This experiment confirms that some movements of the hand can be determined from analysis of the signals detected from the non-contact sensors.

description: We have used the Submillimeter Array to image a flux-limited sample of seven submillimeter galaxies, selected by the AzTEC camera on the JCMT at 1.1 mm, in the COSMOS field at 890 μ m with ~2'' resolution. All of the sources—two radio-bright and five radio-dim—are detected as single point sources at high significance (>6 σ), with positions accurate to ~0.2'' that enable counterpart identification at other wavelengths observed with similarly high angular resolution. All seven have IRAC counterparts, but only two have secure counterparts in deep HST ACS imaging. As compared to the two radio-bright sources in the sample, and those in previous studies, the five radio-dim sources in the sample (1) have systematically higher submillimeter-to-radio flux ratios, (2) have lower IRAC 3.6-8.0 μ m fluxes, and (3) are not detected at 24 μ m . These properties, combined with size constraints at 890 μ m (θ 1.2''), suggest that the radio-dim submillimeter galaxies represent a population of very dusty starbursts, with physical scales similar to local ultraluminous infrared galaxies, with an average redshift higher than radio-bright sources.

description: We deﬁne a generalized strategy eliminability criterion for bimatrix games that considers whether a given strategy is eliminable relative to given dominator & eliminee subsets of the players’ strategies. We show that this deﬁnition spans a spectrum of eliminability criteria from strict dominance (when the sets are as small as possible) to Nash equilibrium (when the sets are as large as possible). We show that checking whether a strategy is eliminable according to this criterion is coNPcomplete (both when all the sets are as large as possible and when the dominator sets each have size 1). We then give an alternative deﬁnition of the eliminability criterion and show that it is equivalent using the Minimax Theorem. We show how this alternative deﬁnition can be translated into a mixed integer program of polynomial size with a number of (binary) integer variables equal to the sum of the sizes of the eliminee sets, implying that checking whether a strategy is eliminable according to the criterion can be done in polynomial time, given that the eliminee sets are small. Finally, we study using the criterion for iterated elimination of strategies.

description: Despite the importance of ligand dissociation energies for computational chemistry, obtaining accurate ab initio reference data is difficult and density-functional methods of uncertain reliability are chosen for feasibility reasons. Here, we consider advanced coupled-cluster and multi-configurational approaches to reinvestigate our WCCR10 set of ten gas-phase ligand dissociation energies. We assess the potential multi-configurational character of all molecules involved in these reactions in order to determine where single-reference coupled-cluster approaches can be applied. For some reactions of the WCCR10 set, large deviations from density-functional results including semiclassical dispersion corrections from experimental reference data had been observed. We tackle the issue (i) by comparing to ab initio data that comprise dispersion effects on a rigorous first-principles footing and (ii) by a comparison of density-functional approaches that model dispersion interactions in various ways. Only for two reactions, species exhibiting nonnegligible static electron correlation were identified, and hence, we may choose standard single-reference coupled-cluster approaches to compare with density-functional methods for the other eight reactions. For WCCR10, the Minnesota M06-L functional yielded the smallest mean absolute deviation without additional dispersion corrections in comparison to the coupled-cluster results and the PBE0-D3 functional produced the overall smallest mean absolute deviation. The agreement of density-functional results with coupled-cluster data increases significantly upon inclusion of any type of dispersion correction. It is important to emphasize that different density-functional schemes available for this purpose perform equally well. The coupled-cluster dissociation energies, however, deviate significantly from experimental results.

description: In this paper, we investigate a dual class of bi-polarization indices, namely rank-dependent bi-polarization indices. We show that these indices may be characterized with the generalized positional transfer sensitivity property. We find necessary and sufficient conditions in order to identify bi-polarization-reducing marginal tax reforms. Precisely, we propose inverse positional dominance criteria based on the comparison of bi-polarization concentration curves. An illustration is presented using the Jordanian Household Expenditure and Income Survey 2002/2003. / Dans cet article nous analysons une classe d’indices de bi-polarisation basés sur le rang des individus dans la distribution des revenues. Nous démontrons que ces indices peuvent être caractérisés par des principes de transferts généralisés. Nous identifions une condition nécessaire et suffisante permettant d’identifier les réformes fiscales marginales permettant de réduire la bi-polarisation. La méthode est illustrée à l’aide de données du Jordanian Household Expenditure and Income Survey 2002/2003.

THROUGH THE LOOKING GLASS, INTO BATTLEFIELD HERONGATE: REFLECTING ON A SITE IN CRISIS AS AN OUTSIDER
Creators: name: Saxena, Astha
Publisher: name: My University
Year: 2021

description: This paper looks into the story of Herongate, a site to be gentrified in Ottawa, Canada, to understand what home means for the people experiencing displacement due to Gentrification. Herongate is a stigmatized and racialized neighbourhood in Ottawa. Herongate is comprised primarily of the economically weaker section of society. The people have battled for tenant rights and against forced displacement since 2016. Several factors have been involved in how this battle has played out. Foucault’s concepts of heterotopias explain that the “untamed urban spaces” are tools to contain spaces of crisis and uphold the illusions of urban utopia. The urban discourses are often selective in what they acknowledge about urban lives. The strengths of poorer neighbourhoods often go unacknowledged. People who peek into these heterotopias of urban poverty are limited by their prisms that are shaped by these urban illusions. The paper employs self-reflection as the method to understand how outsiders understand housing injustice and how labels of immigrant visible minorities affect such spaces. Since the author is an international student from India, the paper compares the urban poor in Ottawa and cities across India, discovering the limitations of the author’s prisms as an outsider. Herongate’s newsletter, Herongate’s public meetings and the scholarly works about Herongate weave a complicated but inspiring story about what has happened at Herongate and how the tenants battled evictions. The paper traverses the narratives built different mediums, trying to understand the limits of an outsider's perspective.
