description: In the context of End-to-End testing of web applications, automated exploration techniques (a.k.a. crawling) are widely used to infer state-based models of the site under test. These models, in which states represent features of the web application and transitions represent reachability relationships, can be used for several model-based testing tasks, such as test case generation. However, current exploration techniques often lead to models containing many near-duplicate states, i.e., states representing slightly different pages that are in fact instances of the same feature. This has a negative impact on the subsequent model-based testing tasks, adversely affecting, for example, size, running time, and achieved coverage of generated test suites. As a web page can be naturally represented by its tree-structured DOM representation, we propose a novel near-duplicate detection technique to improve the model inference of web applications, based on Tree Kernel (TK) functions. TKs are a class of functions that compute similarity between tree-structured objects, largely investigated and successfully applied in the Natural Language Processing domain. To evaluate the capability of the proposed approach in detecting near-duplicate web pages, we conducted preliminary classification experiments on a freely-available massive dataset of about 100k manually annotated web page pairs. We compared the classification performance of the proposed approach with other state-of-the-art near-duplicate detection techniques. Preliminary results show that our approach performs better than state-of-the-art techniques in the near-duplicate detection classification task. These promising results show that TKs can be applied to near-duplicate detection in the context of web application model inference, and motivate further research in this direction.

description: In this experiment we aim to detect Kaluza-Klein (KK) excitations of the bulk gauge field, emitted in a bremsstrahlung process on solar plasma constituents, by looking at a process analogous to the photoelectric effect inside the HPGe detector. Using a generic feature of the underlying effective theory that the unknown 4-dimensional gauge coupling is independent of the number of extra large dimensions delta, we show that the expected number of events in the detector is insensitive to the true scale of quantum gravity for delta=2. With the entire data collection time of 202 days in the energy interval 1.7 - 3.8 keV, the number of events detected was as low as 1.1x10^6, compared to 2.7x10^6 from the expected high multiplicity of the solar KK excitations for delta =2. Hence, our bound from the presumed existence of new forces associated with additional gauge bosons actually conforms with very stringent bounds set from various astrophysical considerations. Baring any modifications of the infrared part of the KK spectrum, this bound would therefore rule out the possibility of observing any signal at the LHC for delta=2. Although a dependence on the fundamental scale referring to 4+delta-dimensional gravity turns on again for delta=3, the experimental sensitivity of the present setup proves insufficient to draw any constraint for delta>2.

description: We investigate the asymptotic normality of the posterior distribution in the discrete setting, when model dimension increases with sample size. We consider a probability mass function $θ_0$ on $\mathbbm{N}\setminus \{0\}$ and a sequence of truncation levels $(k_n)_n$ satisfying $k_n^3\leq n\inf_{i\leq k_n}θ_0(i).$ Let $\hatθ$ denote the maximum likelihood estimate of $(θ_0(i))_{i\leq k_n}$ and let $Δ_n(θ_0)$ denote the $k_n$-dimensional vector which $i$-th coordinate is defined by \sqrt{n} (\hatθ_n(i)-θ_0(i)) for $1\leq i\leq k_n.$ We check that under mild conditions on $θ_0$ and on the sequence of prior probabilities on the $k_n$-dimensional simplices, after centering and rescaling, the variation distance between the posterior distribution recentered around $\hatθ_n$ and rescaled by $\sqrt{n}$ and the $k_n$-dimensional Gaussian distribution $\mathcal{N}(Δ_n(θ_0),I^{-1}(θ_0))$ converges in probability to $0.$ This theorem can be used to prove the asymptotic normality of Bayesian estimators of Shannon and Rényi entropies. The proofs are based on concentration inequalities for centered and non-centered Chi-square (Pearson) statistics. The latter allow to establish posterior concentration rates with respect to Fisher distance rather than with respect to the Hellinger distance as it is commonplace in non-parametric Bayesian statistics.

description: Replicability is at the core of the scientific enterprise. In the past 30 years, recurring concerns about the extent of replicability (or lack thereof) of the research in various disciplines have surfaced, including in economics.

In this talk, I describe the context in which the current discussion in the social science is occurring: what are the definitions of replicability and reproducibility, what is failing, and to what extent. In particular, I discuss the concerns in economics: to what extent is this a problem in economics, what are the approaches that are being considered, and what are the possible broader implications of those approaches. Finally, I discuss the concrete measures that are being implemented under my guidance at the American Economic Association, and that are being discussed in the broader economics community.

The solutions to these problems will change the way research will be taught and conducted, in economics in particular, and in the social sciences more broadly. The implications affect undergraduate and graduate teaching, research infrastructure, and habits.

title: Consuming identities: the culture and politics of food among the Uyghur in contemporary Xinjiang
Creators: name: Cesaro, Maria Cristina
Publisher: name: University of Kent
Year: 2002

description: This research is a study of food and identity among the Uyghur, a Turkic-speaking Muslim people who live in the north-western region of Xinjiang (Chinese Central Asia) and are today one of the largest minorities in the People's Republic of China. It is based on fieldwork carried out from May 1996 to September 1997 among Uyghur urban intellectuals in Urilmchi, the provincial capital of Xinjiang. The underlying argument is that food, in all its related practices, is a powerful form of identity creation and maintenance. Through the preparation, the exchange, and the consumption of food social relationships are created, rules of inclusion and exclusion are established, boundaries are negotiated and maintained. In a context of volatile relations between the Uyghur Muslim minority and the dominant Han Chinese population, food represents a fundamental resource available to Uyghur intellectuals, who find themselves at the vanguard of both assimilation and differentiation and are currently engaged in a difficult process of negotiation and affirmation of their distinctive identity. In this context, food becomes a privileged arena for negotiation, providing an excellent vantage point to explore the dynamic and complex nature of social and cultural interaction in contemporary Xinjiang. In particular, the same tension between differentiation and assimilation is at work in the realm of food. If, on the one hand, a narrative of continuity, tradition, and discrete identities can be detected in the way Uyghurs talk and write about their food, on the other hand practices as well as discourses also show the syncretic nature of a culinary tradition.

description: A colloidal system of spheres interacting with both a deep and narrow attractive potential and a shallow long-ranged barrier exhibits a prepeak in the static structure factor. This peak can be related to an additional mesoscopic length scale of clusters and/or voids in the system. Simulation studies of this system have revealed that it vitrifies upon increasing the attraction into a gel-like solid at intermediate densities. The dynamics at the mesoscopic length scale corresponding to the prepeak represents the slowest mode in the system. Using mode coupling theory with all input directly taken from simulations, we reveal the mechanism for glassy arrest in the system at 40% packing fraction. The effects of the low-q peak and of polydispersity are considered in detail. We demonstrate that the local formation of physical bonds is the process whose slowing down causes arrest. It remains largely unaffected by the large-scale heterogeneities, and sets the clock for the slow cluster mode. Results from mode-coupling theory without adjustable parameters agree semi-quantitatively with the local density correlators but overestimate the lifetime of the mesoscopic structure (voids).

description: We introduce a new method for computing massless Feynman integrals analytically in parametric form. An analysis of the method yields a criterion for a primitive Feynman graph $G$ to evaluate to multiple zeta values. The criterion depends only on the topology of $G$, and can be checked algorithmically. As a corollary, we reprove the result, due to Bierenbaum and Weinzierl, that the massless 2-loop 2-point function is expressible in terms of multiple zeta values, and generalize this to the 3, 4, and 5-loop cases. We find that the coefficients in the Taylor expansion of planar graphs in this range evaluate to multiple zeta values, but the non-planar graphs with crossing number 1 may evaluate to multiple sums with $6^\mathrm{th}$ roots of unity. Our method fails for the five loop graphs with crossing number 2 obtained by breaking open the bipartite graph $K_{3,4}$ at one edge.
Contribution of pressure to the energy-momentum density in a moving perfect fluid: A physical perspective

description: In the energy-momentum density expressions for a relativistic perfect fluid with a bulk motion, one comes across a couple of pressure-dependent terms, which though well known, are to an extent, lacking in their conceptual basis and the ensuing physical interpretation. In the expression for the energy density, the rest mass density along with the kinetic energy density of the fluid constituents due to their random motion, which contributes to the pressure as well, are already included. However, in a fluid with a bulk motion, there are, in addition, a couple of explicit, pressure-dependent terms in the energy-momentum densities, whose presence to an extent, is shrouded in mystery, especially from a physical perspective. We show here that one such pressure-dependent term appearing in the energy density, represents the work done by the fluid pressure against the Lorentz contraction during transition from the rest frame of the fluid to another frame in which the fluid has a bulk motion. This applies equally to the electromagnetic energy density of electrically charged systems in motion and explains in a natural manner an apparently paradoxical result that the field energy of a charged capacitor system decreases with an increase in the system velocity. The momentum density includes another pressure-dependent term, that represents an energy flow across the system, due to the opposite signs of work being done by pressure on two opposite sides of the moving fluid. From Maxwell's stress tensor we demonstrate that in the expression for electromagnetic momentum of an electric charged particle, it is the presence of a similar pressure term, arising from electrical self-repulsion forces in the charged sphere, that yields a natural solution for the notorious, more than a century old but thought by many as still unresolved, 4/3 problem in the electromagnetic momentum.

description: We extend the covariant analysis of the brane cosmological evolution in order to take into account, apart from a general matter content and an induced-gravity term on the brane, a Gauss-Bonnet term in the bulk. The gravitational effect of the bulk matter on the brane evolution can be described in terms of the total bulk mass as measured by a bulk observer at the location of the brane. This mass appears in the effective Friedmann equation through a term characterized as generalized dark radiation that induces mirage effects in the evolution. We discuss the normal and self-accelerating branches of the combined system. We also derive the Raychaudhuri equation that can be used in order to determine if the cosmological evolution is accelerating.

description: We propose a new approach to determine the strength of the charge symmetry breaking (CSB) term in the framework of nuclear density functional theory. It is shown that once ab initio calculations are available including accurate description of isospin symmetry breaking terms in medium and heavy nuclei, the mass difference of mirror nuclei as well as the neutron-skin thickness of doubly-closed-shell nuclei can be used to constrain the strength of the CSB interaction with an uncertainty less than $ 6 \, \% $, separately from other isospin symmetry breaking forces. This method opens a new vista of ab initio nuclear energy density functionals.

description: We present an experimental and numerical study of a terahertz metamaterial with a nonlinear response that is controllable via the relative structural positioning of two stacked split ring resonator arrays. The first array is fabricated on an n-doped GaAs substrate and the second array is fabricated vertically above the first using a polyimide spacer layer. Due to GaAs carrier dynamics, the on-resonance terahertz transmission at 0.4 THz varies in a nonlinear manner with incident terahertz power. The second resonator layer dampens this nonlinear response. In samples where the two layers are aligned, the resonance disappears and total nonlinear modulation of the on-resonance transmission decreases. The nonlinear modulation is restored in samples where an alignment offset is imposed between the two resonator arrays. Structurally tunable metamaterials can therefore act as a design template for tunable nonlinear THz devices by controlling the coupling of confined electric fields to nonlinear phenomena in a complex material substrate or inclusion.
Sovereign immunity and transnational arbitration
Creators: name: Chukwumerije, Okezie
Publisher: name: University of British Columbia
Year: 2010

description: State participation in the arbitration of transnational commercial disputes is steadily increasing. It is estimated that arbitration of state contract disputes presently constitute one quarter of the disputes submitted to ICC arbitration. Where a state party is involved in an arbitration, the sovereign immunity doctrine - which in some cases exempts foreign states from the jurisdiction of municipal courts - may have adverse effect on the arbitration process. The thesis explores the impact of the immunity doctrine on the arbitration of state contract disputes. State practice in selected jurisdictions is used to illustrate the methods adopted in an effort to mitigate the impact of the immunity doctrine on commercial arbitration. In this respect, focus is placed on both jurisdictional immunity and immunity from execution. The thesis concludes that the private party may avoid unnecessary litigation by requiring the state party to expressly waive its immunity both during the recognition and enforcement stages. The waiver should be included in the arbitration agreement.

description: We study human dynamics by analyzing Linux history files. The goodness-of-fit test shows that most of the collected datasets belong to the universality class suggested in the literature by a variable-length queueing process based on priority. In order to check the validity of this model, we design two tests based on mutual information between time intervals and a mathematical relationship known as the arcsine law. Since the previously suggested queueing process fails to pass these tests, the result suggests that the modelling of human dynamics should properly consider the statistical dependency in the temporal dimension.

description: Sampling the collective, dynamical fluctuations that lead to nonequilibrium pattern formation requires probing rare regions of trajectory space. Recent approaches to this problem based on importance sampling, cloning, and spectral approximations, have yielded significant insight into nonequilibrium systems, but tend to scale poorly with the size of the system, especially near dynamical phase transitions. Here we propose a machine learning algorithm that samples rare trajectories and estimates the associated large deviation functions using a many-body control force by leveraging the flexible function representation provided by deep neural networks, importance sampling in trajectory space, and stochastic optimal control theory. We show that this approach scales to hundreds of interacting particles and remains robust at dynamical phase transitions.

description: In a rigorous construction of the path integral for supersymmetric quantum mechanics on a Riemann manifold, based on Bär and Pfäffle's use of piecewise geodesic paths, the kernel of the time evolution operator is the heat kernel for the Laplacian on forms. The path integral is approximated by the integral of a form on the space of piecewise geodesic paths which is the pullback by a natural section of Mathai and Quillen's Thom form of a bundle over this space. In the case of closed paths, the bundle is the tangent space to the space of geodesic paths, and the integral of this form passes in the limit to the supertrace of the heat kernel.

description: We report the preparation of exactly one $^{87}$Rb atom and one $^{133}$Cs atom in the same optical tweezer as the essential first step towards the construction of a tweezer array of individually trapped $^{87}$Rb$^{133}$Cs molecules. Through careful selection of the tweezer wavelengths, we show how to engineer species-selective trapping potentials suitable for high-fidelity preparation of Rb $+$ Cs atom pairs. Using a wavelength of 814~nm to trap Rb and 938~nm to trap Cs, we achieve loading probabilities of $0.508(6)$ for Rb and $0.547(6)$ for Cs using standard red-detuned molasses cooling. Loading the traps sequentially yields exactly one Rb and one Cs atom in $28.4(6)\,\%$ of experimental runs. Using a combination of an acousto-optic deflector and a piezo-controlled mirror to control the relative position of the tweezers, we merge the two tweezers, retaining the atom pair with a probability of $0.99^{(+0.01)}_{(-0.02)}$. We use this capability to study hyperfine-state-dependent collisions of Rb and Cs in the combined tweezer and compare the measured two-body loss rates with coupled-channel quantum scattering calculations.

Parochlus kiefferi

description: Parochlus kiefferi (Garrett 1925)
On a cross-country skiing trip on 20 February 2015 in the Krkonoše Mountains National Park (Giant Mts.) VS collected a tuft of decomposing vegetation with mosses from a helocrene spring located just next to a ski-track (Fig. 2). This spring is usually covered with snow in the winter, but due to the combination of lack of snowfall during the previous days, sunny weather and slope exposition to the south, it was uncommonly snow-free at that time. The inspection of the collected material back in the laboratory revealed one larva of Parochlus.
The identification of Parochlus larvae into species is not possible, but only a single species P. kiefferi is known from the northern hemisphere. Thus, the collected specimen most certainly belongs to this species.
P. kiefferi seems to be cold-stenothermic, living mostly in cold springs and upper courses of spring-fed streams (Brundin 1966). It was also reported from large streams with strong current in North America (Brundin 1966) or from moss in a pond fed by ice-melt water in Italian Alps (Lencioni et al. 2007).
It is possible that the species emerges just after the snow melts and is no longer present at the locality, as was observed by Wülker (1958) in Feldberg springs. Such phenology would prevent the species from being recorded by conventional sampling, which is usually carried out in the vegetation season. It is worth noting, however, that in some regions the species emerges practically throughout the whole snow-free period: from the beginning of June to the beginning of October in Swedish mountains or from the end of April to the beginning of November in temperate Canada (Brundin 1966). In the Italian Alps, Lencioni et al. (2007) recorded a pupal exuviae in the middle of September. Please see Table 1 for summarized information.

On polynomial invariants of several qubits

description: It is a recent observation that entanglement classification for qubits is closely related to local $SL(2,\CC)$-invariants including the invariance under qubit permutations, which has been termed $SL^*$ invariance. In order to single out the $SL^*$ invariants, we analyze the $SL(2,\CC)$-invariants of four resp. five qubits and decompose them into irreducible modules for the symmetric group $S_4$ resp. $S_5$ of qubit permutations. A classifying set of measures of genuine multipartite entanglement is given by the ideal of the algebra of $SL^*$-invariants vanishing on arbitrary product states. We find that low degree homogeneous components of this ideal can be constructed in full by using the approach introduced in [Phys. Rev. A 72, 012337 (2005)]. Our analysis highlights an intimate connection between this latter procedure and the standard methods to create invariants, such as the $Ω$-process. As the degrees of invariants increase, the alternative method proves to be particularly efficient.

description: Performing reliability analysis on complex systems is often computationally expensive. In particular, when dealing with systems having high input dimensionality, reliability estimation becomes a daunting task. A popular approach to overcome the problem associated with time-consuming and expensive evaluations is building a surrogate model. However, these computationally efficient models often suffer from the curse of dimensionality. Hence, training a surrogate model for high-dimensional problems is not straightforward. Henceforth, this paper presents a framework for solving high-dimensional reliability analysis problems. The basic premise is to train the surrogate model on a low-dimensional manifold, discovered using the active subspace algorithm. However, learning the low-dimensional manifold using active subspace is non-trivial as it requires information on the gradient of the response variable. To address this issue, we propose using sparse learning algorithms in conjunction with the active subspace algorithm; the resulting algorithm is referred to as the sparse active subspace (SAS) algorithm. We project the high-dimensional inputs onto the identified low-dimensional manifold identified using SAS. A high-fidelity surrogate model is used to map the inputs on the low-dimensional manifolds to the output response. We illustrate the efficacy of the proposed framework by using three benchmark reliability analysis problems from the literature. The results obtained indicate the accuracy and efficiency of the proposed approach compared to already established reliability analysis methods in the literature.

description: The recent detection of the hydrocarbon anion C6H- in the interstellar medium has led us to investigate the synthesis of hydrocarbon anions in a variety of interstellar and circumstellar environments. We find that the anion/neutral abundance ratio can be quite large, on the order of at least a few percent, once the neutral has more than five carbon atoms. Detailed modeling shows that the column densities of C6H- observed in IRC+10216 and TMC-1 can be reproduced. Our calculations also predict that other hydrocarbon anions, such as C4H- and C8H-, are viable candidates for detection in IRC+10216, TMC-1 and photon-dominated regions such as the Horsehead Nebula.

description: Quantile regression provides a framework for modeling statistical quantities of interest other than the conditional mean. The regression methodology is well developed for linear models, but less so for nonparametric models. We consider conditional quantiles with varying coefficients and propose a methodology for their estimation and assessment using polynomial splines. The proposed estimators are easy to compute via standard quantile regression algorithms and a stepwise knot selection algorithm. The proposed Rao-score-type test that assesses the model against a linear model is also easy to implement. We provide asymptotic results on the convergence of the estimators and the null distribution of the test statistic. Empirical results are also provided, including an application of the methodology to forced expiratory volume (FEV) data.

description: The water-graphite interaction potential proposed recently (González et al.\emph{J. Phys. Chem. C} \textbf{2007}, \emph{111}, 14862), the three TIP$N$P ($N=3,\:4,\:5$) water-water interaction models, and basin-hopping global optimization are used to find the likely candidates for the global potential energy minima of (H$_{2}$O)$_{n}$ clusters with $n\leq21$ on the (0001)-surface of graphite and to perform a comparative study of these minima. We show that, except for the smaller clusters ($n<6$), for which ab-initio results are available, the three water-water potential models provide mostly inequivalent conformations. While TIP3P seems to favor monolayer water structures for $n<18$, TIP4P and TIP5P favor bilayer or volume structures for $n>6$. These $n$ values determine the threshold of dominance of the hydrophobic nature of the water-graphite interaction at the nanoscopic scale for these potential models.

description: Source code summaries are important for program comprehension and maintenance. However, there are plenty of programs with missing, outdated, or mismatched summaries. Recently, deep learning techniques have been exploited to automatically generate summaries for given code snippets. To achieve a profound understanding of how far we are from solving this problem and provide suggestions to future research, in this paper, we conduct a systematic and in-depth analysis of 5 state-of-the-art neural code summarization models on 6 widely used BLEU variants, 4 pre-processing operations and their combinations, and 3 widely used datasets. The evaluation results show that some important factors have a great influence on the model evaluation, especially on the performance of models and the ranking among the models. However, these factors might be easily overlooked. Specifically, (1) the BLEU metric widely used in existing work of evaluating code summarization models has many variants. Ignoring the differences among these variants could greatly affect the validity of the claimed results. Furthermore, we conduct human evaluations and find that the metric BLEU-DC is most correlated to human perception; (2) code pre-processing choices can have a large (from -18\% to +25\%) impact on the summarization performance and should not be neglected. We also explore the aggregation of pre-processing combinations and boost the performance of models; (3) some important characteristics of datasets (corpus sizes, data splitting methods, and duplication ratios) have a significant impact on model evaluation. Based on the experimental results, we give actionable suggestions for evaluating code summarization and choosing the best method in different scenarios. We also build a shared code summarization toolbox to facilitate future research.

Victor Hugo e il fou du roi: variazioni su un tipo

description: Nel teatro vittorhughiano il buffone è personaggio centrale a più di un titolo: partecipa alla contestualizzazione storica del dramma e a quel principio di ricostruzione storica che è basilare nel teatro romantico, rientra in quella ricerca della spettacolarità che è ugualmente un aspetto tra i più rilevanti del teatro di Hugo, ed è inoltre una delle incarnazioni più tipiche del grottesco, principio teorico fondante della sua poetica teatrale.

Il contributo propone una lettura trasversale e comparativa di alcuni drammi (Cromwell, Marion Delorme, Le roi s’amuse), allo scopo di ricostruire un quadro d’insieme relativamente a questo tipo drammatico e alla sua evoluzione, mostrandone anche le ricadute nell’opera verdiana.

description: To confirm previously reported evidence of high-temperature superconductivity in laser processed Sr-Ru-O, we performed simultaneous two-probe and four-probe resistive measurements using bar-geometry samples. A superconducting-type transition with an onset at about 250K was recorded in one of the samples, consistent with our previously reported measurements in the X-bridge geometry. Some compositional details of the samples are also provided which were not known at the time of previous web-publication.
A history of the Okanagan : Indians and whites in the settlement era, 1860-1920
Creators: name: Thomson, Duncan Duane
Publisher: name: University of British Columbia

description: This study’s primary focus is on white settlement and Indian dispossession and marginalizatian, the theme being developed in the context of a comprehensive local history A number of sub-themes are developed including the relationship between political power and landholding, the changing role of chiefs in Indian society, the importance of the railway in consolidating economic power, the connection between transportation and changing industrial activity and the significance of land tenure regimes in economic performance. After an introduction and outline history the paper is organized in three parts. The first deals with the institutions which supported settlers and were imposed upon Indians. The four institutions examined are missionary activity as it related to Indians and the political, judicial and educational structures as they affected Indians and whites. The notable characteristic of these institutions is that the services delivered to the two racial groups were markedly different, that Indians never received the benefit of their support. The second section considers the critical question of Indian access to resources, the conditions under which reserves were assigned and then repeatedly altered, and the question of aboriginal rights to the land The discrepancy in the terms in which whites and Indians could claim land and the insecurity of tenure of Indians is documented. The third section considers economic sectors: hunting, fishing and gathering, mining, stockraising and agriculture. In the latter two industries, pursued by both Indians and whites, the two communities are juxtaposed to observe differences in their conduct of those industries. The critical elements determining different performance are identified as the differing quantities of obtainable land, and the land and water tenure regimes under which the participants operated although other factors such as increasing capitalization, an oppressive Department of Indian affairs, inadequate access to education and health services and restricted rights in the political and judicial spheres were contributing factors. Okanagan society in the pre-World War I era is seen as a racist society, one in which a completely different set of rules existed for each race and in which social distance between races increased over time White settlers succeeded in building a society with all the features of the modern world: well developed transportation and communications, urban centres, supportive social service institutions, and an educated and prosperous population, in short, a harmonious and just society But this development occured at the expense of the Indian Population. As a society they could only be characterized as a dependent, impoverished, diseased and illiterate people, prone to alcohol and appearing to lack in ambition White success was built upon Indian dispossession.
