description: We study the scaling of logarithmic negativity between adjacent subsystems in critical fermion chains with various inhomogeneous modulations through numerically calculating its recently established lower and upper bounds. For random couplings, as well as for a relevant aperiodic modulation of the couplings, which induces an aperiodic singlet state, the bounds are found to increase logarithmically with the subsystem size, and both prefactors agree with the predicted values characterizing the corresponding asymptotic singlet state. For the marginal Fibonacci modulation, the prefactors in front of the logarithm are different for the lower and the upper bound, and vary smoothly with the strength of the modulation. In the delocalized phase of the quasi-periodic Harper model, the scaling of the bounds of the logarithmic negativity as well as that of the entanglement entropy are compatible with the logarithmic scaling of the homogeneous chain. At the localization transition, the scaling of the above entanglement characteristics holds to be logarithmic, but the prefactors are significantly reduced compared to those of the translationally invariant case, roughly by the same factor.

description: The beef sector in North America, as in much of Europe, has not industrialized as rapidly as other animal production industries (pork, poultry). At the same time, the market share for beef in household meat consumption has dwindled. Apart from a penalizing price effect, various studies in North America (Wachenhein and Singley, 1999; Goldsmith et al., 2002; Schroeder and Kovanda, 2003) have accounted for this in terms of a lack of vertical coordination in the sector, the absence of a channel captain at the processing stage, and the dearth of product differentiation initiatives directed at customer expectations. The purpose of this contribution is to analyse the case of the French beef sector and to compare and contrast findings with the situation described in the United States and Canada.

description: The aim of the article is to discuss the notion of religious space in David Macaulay’s Mosque through the exploration of the architecture of the mosque not only as a structure serving religious purposes but also a space of social activity bringing together the members of the community. Macaulay created Mosque as a response to the 9/11 attacks and its complex political and socio cultural global impact. Through the deployment of the mosque as a conceptual framework the notions of mobility, displacement and belonging are addressed as intersecting factors forging communal and individual identities.

description: We present high resolution near-infrared spectropolarimetric observations using the SPIRou instrument at CFHT during a transit of the recently detected young planet AU Mic b, with supporting spectroscopic data from iSHELL at IRTF. We detect Zeeman signatures in the Stokes V profiles, and measure a mean longitudinal magnetic field of $\overline{B}_\ell=46.3\pm0.7$~G. Rotationally modulated magnetic spots likely cause long-term variations of the field with a slope of $d{B_\ell}/dt=-108.7\pm7.7$~G/d. We apply the cross-correlation technique to measure line profiles and obtain radial velocities through CCF template matching. We find an empirical linear relationship between radial velocity and $B_\ell$, which allows us to estimate the radial velocity variations which stellar activity induces through rotational modulation of spots for the five hours of continuous monitoring of AU Mic with SPIRou. We model the corrected radial velocities for the classical Rossiter-McLaughlin effect, using MCMC to sample the posterior distribution of the model parameters. This analysis shows that the orbit of AU Mic b is prograde and aligned with the stellar rotation axis with a sky-projected spin-orbit obliquity of $λ=0^{+18}_{-15}$ degrees. The aligned orbit of AU Mic b indicates that it formed in the protoplanetary disk that evolved to the current debris disk around AU Mic.

description: The use of photonic crystal and negative refractive index materials is known to improve resolution of optical microscopy and lithography devices down to 80 nm level. Here we demonstrate that utilization of well-known digital image recovery techniques allows us to further improve resolution of optical microscope down to 30 nm level. Our microscope is based on a flat dielectric mirror deposited onto an array of nanoholes in thin gold film. This two-dimensional photonic crystal mirror may have either positive or negative effective refractive index as perceived by surface plasmon polartions in the visible frequency range. The optical images formed by the mirror are enhanced using simple digital filters.

description: Attaining accurate average structural properties in a molecular simulation should be considered a prerequisite if one aims to elicit meaningful insights into a system's behavior. For charged surfaces in contact with an electrolyte solution, an obvious example is the density profile of ions along the direction normal to the surface. Here we demonstrate that, in the slab geometry typically used in simulations, imposing an electric displacement field $D$ determines the integrated surface charge density of adsorbed ions at charged interfaces. This allows us to obtain macroscopic surface charge densities irrespective of the slab thickness used in our simulations. We also show that the commonly used Yeh-Berkowitz method and the 'mirrored slab' geometry both impose vanishing integrated surface charge density. We present results both for relatively simple rocksalt (111) interfaces, and the more complex case of kaolinite's basal faces in contact with aqueous electrolyte solution.

description: Cook’s (1995) life cycle theory of cooperatives predicts a rise and fall of cooperatives over time. He argues that cooperatives arise as a response, by producers or consumers, to some form of inefficiency in a market structure, for example an oligopoly. In such a market, the cooperative can thrive by replacing the ineffective firms until other firms or institutions or technology come along and deliver even better service. When this happens, the cooperative’s ownership and control features may hamper its ability to grow and compete. According to Cook, the cooperative will eventually need to change in order to accommodate investors, or it will be forced to exit the market. This article considers the case of Australia’s grain market within Cook’s framework to see if it has behaved as predicted and where it is heading in terms of responding to the needs of the agents in the market chain. In the 1980s Australia’s grain cooperatives and institutions faced challenges from deregulation and changing market structure that exposed extensive inefficiency in the traditional cooperative ownership arrangements. This article will review the origins, successes and eventual transformation of Australia’s major grain marketing institutions.

description: We describe a simple method to experimentally determine the frequency dependencies of the per-unit-length resistance and conductance of transmission lines. The experiment is intended as a supplement to the classic measurement of the transient response of a transmission line to a voltage step or pulse. In the transient experiment, an ideal (lossless) model of the transmission line is used to determine the characteristic impedance and signal propagation speed. In our experiment, the insertion losses of various coaxial cables are measured as a function of frequency from 1 to 2000 MHz. A full distributed circuit model of the transmission line that includes both conductor and dielectric losses is needed to fit the frequency dependence of the measured insertion losses. Our model assumes physically-sensible frequency dependencies for the per-unit-length resistance and conductance that are determined by the geometry of the coaxial transmission lines used in the measurements.

Free Will and Physics

description: The abstract concept of indeterministic free will is distinguished from the phenomenon of free will. Evidence for the abstract concept is examined and critically compared with various designs of automata. It is concluded that there is no evidence to support the abstract concept of indeterministic free will, it is inconceivable that a test could be constructed to distinguish an indeterministic agent from a complicated automaton. Testing the free will of an alien visitor is introduced to separate prejudices about who has free will from objective experiments. The phenomenon of free will is modelled with a deterministic decision making agent. The agent values independence and satisfies a desire for independence by responding to challenges. When the agent generates challenges internally it will establish a record of being able to do otherwise. In principle a computer could be built with a free will property. The model also explains false attributions of free will (superstitions).

“As Soon As Ever She Died, the Hauntings Began”: Revisiting the Victorian Fallen Woman as a Gothic Archetype in Susan Hill’s The Woman in Black
Creators: name: Miquel-Baldellou, Marta

Year: 2021

description: From the perspective of Neo-Victorian studies, it can be claimed that the character of the Woman in Black in Susan Hill’s eponymous novel, published in 1983, is based on Victorian portrayals of the myth of “the fallen woman.” These Victorian representations often highlight mythemes pertaining to Gothic archetypes, such as the ghost, the vampire, the madwoman and the witch, giving evidence of the association between “the fallen woman” and Kristeva’s notion of the abject, which involves the feeling of subjective horror upon the blurring of what is self and what is other. Hill’s reinterpretation of the myth of “the fallen woman” recaptures Gothic mythemes pervading Victorian representations, but, in contrast with most of these Victorian portrayals, the Woman in Black arises as an actual Gothic archetype insofar as she is a female ghost who is brought back to life to vindicate herself and perpetuate her haunting existence. This article aims at analyzing the intertextuality existing between Hill’s portrayal of the Woman in Black and Victorian representations of “the fallen woman” which resort to Gothic mythemes, with the purpose of identifying Hill’s own contribution to reinterpret and update this Victorian myth.

description: In the hope of supporting rural economies, some rural planners suggest fostering food processing firms in rural areas. Locating close to the source of necessary agricultural commodities might give the processors an advantage. However, emerging patterns of product innovations, which affect demand, and process innovations, which lower costs, are tied to firm-level capacities in research and development. Communities can become more efficient at supplying services, including research services, to a particular industry. This in turn lowers the costs of that industry, driving up demand for the services and so on. The agglomerations of service firms spin off supporting services, which accommodate yet more firms. Agglomerations of service firms are difficult to support in a rural community. Individual firms in rural areas have trouble meeting their own labour needs, let alone the needs of their service sector. The two forces of low transportation costs for commodity inputs versus lowered costs from agglomerations can leave the optimal location for a food processing firm unclear. Urban settings will deliver more agglomerations, but rural settings might allow for cheaper commodity inputs. One of the key factors in a firm’s success is the rate of innovation. This study looked at the rate of innovation in food processing firms across western Canada and tested whether this rate was affected by a firm’s location or by the human capital capacities of the firm or the region surrounding it.

description: We develop a learning strategy to infer the constitutive relation for the stress of polymeric flows with memory. We make no assumptions regarding the functional form of the constitutive relations, except that they should be expressible in differential form as a function of the local stress- and strain-rate tensors. In particular, we use a Gaussian Process regression to infer the constitutive relations from stress trajectories generated from small-scale (fixed strain-rate) microscopic polymer simulations. For simplicity, a Hookean dumbbell representation is used as a microscopic model, but the method itself can be generalized to incorporate more realistic descriptions. The learned constitutive relation is then used to perform macroscopic flow simulations, allowing us to update the stress distribution in the fluid in a manner that accounts for the microscopic polymer dynamics. The results using the learned constitutive relation are in excellent agreement with full Multi-Scale Simulations, which directly couple micro/macro degrees of freedom, as well as the exact analytical solution given by the Maxwell constitutive relation. We are able to fully capture the history dependence of the flow, as well as the elastic effects in the fluid. We expect the proposed learning/simulation approach to be used not only to study the dynamics of entangled polymer flows, but also for the complex dynamics of other Soft Matter systems, which possess a similar hierarchy of length- and time-scales.

description: Τhe present article examines the connection between the Greek stage director Karolos Koun and his staging of modern American drama. Specifically, it investigates the systematic incorporation of plays by writers such as Tennessee Williams and Arthur Miller into the repertoire of Koun’s Art Theater from the Greek Civil War Era to the Cold War period. The aesthetic and ideological choices of the director are placed within the historical and sociopolitical context of Greece, while the connotations of American cultural politics are also taken into consideration. As the article illustrates, Koun used American Realism in order to stage a reflection of global modernity in his locality during the tumultuous years of post-war Greece.

The puzzle of global Double Field Theory: open problems and the case for a Higher Kaluza-Klein perspective
Creators: name: Alfonsi, Luigi
Publisher: name: arXiv
Year: 2020
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: The history of the geometry of Double Field Theory is the history of string theorists' effort to tame higher geometric structures. In this spirit, the first part of this paper will contain a brief overview on the literature of geometry of DFT, focusing on the attempts of a global description. In arXiv:1912.07089 [hep-th] we proposed that the global doubled space is not a manifold, but the total space of a bundle gerbe. This would mean that DFT is a field theory on a bundle gerbe, in analogy with ordinary Kaluza-Klein Theory being a field theory on a principal bundle. In this paper we make the original construction by arXiv:1912.07089 [hep-th] significantly more immediate. This is achieved by introducing an atlas for the bundle gerbe. This atlas is naturally equipped with $2d$-dimensional local charts, where $d$ is the dimension of physical spacetime. We argue that the local charts of this atlas should be identified with the usual coordinate description of DFT. In the last part we will discuss aspects of the global geometry of tensor hierarchies in this bundle gerbe picture. This allows to identify their global non-geometric properties and explain how the picture of non-abelian String-bundles emerges. We interpret the abelian T-fold and the Poisson-Lie T-fold as global tensor hierarchies.

description: Gender is a fragile construction that evolves constantly, through social acceptance and affirmation. A major space for this exchange is the digital sphere where gender is perpetually in the process of redefinition and negotiation. In this context, two online forces with opposing agendas currently put a claim on the future of masculinity: the Manosphere and the Manconomy. The former is devoted to men’s rights, sustaining a traditional view of masculinity, based on misogyny. The latter focuses on the efforts of Manconomy, whose goal is to help men adapt to the changing gender balance in contemporary society. These opposed legions approach male identity from different perspectives, the traditional versus the modernized, each envisioning a different future for the role of men. This paper examines the manifestations of masculinity through the narratives that each side offers in the digital public spaces they occupy (e.g. blogs, social media, and forums) in their effort to reshape the future of masculinity.

Heterostructures of graphene and topological insulators Bi$_2$Se$_3$, Bi$_2$Te$_3$, and Sb$_2$Te$_3$

description: Prototypical three-dimensional topological insulators of the Bi$_2$Se$_3$ family provide a beautiful example of the appearance of the surface states inside the bulk band gap caused by spin-orbit coupling-induced topology. The surface states are protected against back scattering by time reversal symmetry, and exhibit spin-momentum locking whereby the electron spin is polarized perpendicular to the momentum, typically in the plane of the surface. On the other hand, graphene is a prototypical two-dimensional material, with negligible spin-orbit coupling. When graphene is placed on the surface of a topological insulator, giant spin-orbit coupling is induced by the proximity effect, enabling interesting novel electronic properties of its Dirac electrons. We present a detailed theoretical study of the proximity effects of monolayer graphene and topological insulators Bi$_2$Se$_3$, Bi$_2$Te$_3$, and Sb$_2$Te$_3$, and elucidate the appearance of the qualitatively new spin-orbit splittings well described by a phenomenological Hamiltonian, by analyzing the orbital decomposition of the involved band structures. This should be useful for building microscopic models of the proximity effects between the surfaces of the topological insulators and graphene.

Outside directors signaling, monitoring and compensation
Creators: name: Deutsch, Yuval
Publisher: name: University of British Columbia
Year: 2009

description: This thesis is comprised of three essays dealing with outside directors. The first essay addresses the signaling role that outside directors play. This is a role that is especially important for entrepreneurial firms, and has been relatively neglected in corporate governance research. The primary contribution of this chapter is in developing an analytical model and predictive framework on which future empirical and analytical research on directors' signaling role can be based. This chapter also contributes to the signaling theory literature by deriving a new type of equilibrium — the "stochastic separating equilibrium" — which may well be applicable in a broader set of models that incorporate signaling through middlemen. This equilibrium has an important realistic feature in that it permits the coexistence of both high and low quality firms in equilibrium. In the second study, I address directors' monitoring role. This essay examines whether a systematic relationship exists between a board's composition and discrete strategic decisions of a firm, which have been addressed in the literature as involving potential conflicting interests between managers and shareholders. To explore this question, I conducted seven meta-analyses of relevant strategic decisions, on which I could obtain data. The results provide evidence for the presence of systematic relationships between a board's composition and five out of the seven strategies examined. Interestingly, these systematic relationships provide only limited support to the predictions of agency theory, which is the predominant rational behind this line of research. In the third essay, I examine the effects of outside directors' stock-based compensation on one indicator of board monitoring effectiveness: firms' research and development (R&D) intensity. The results suggest that both the percentage of stock-based compensation and the proportion of stock options within it are positively related to firms' R & D expenditures. Moreover, stock-based compensation moderates the relationship between board composition and R & D intensity. These results highlight the need to reevaluate previous findings that addressed the effects of board composition on both firm performance and firm strategic decisions.

Anharmonicity Measure for Materials

description: Theoretical frameworks used to qualitatively and quantitatively describe nuclear dynamics in solids are often based on the harmonic approximation. However, this approximation is known to become inaccurate or to break down completely in many modern functional materials. Interestingly, there is no reliable measure to quantify anharmonicity so far. Thus, a systematic classification of materials in terms of anharmonicity and a benchmark of methodologies that may be appropriate for different strengths of anharmonicity is currently impossible. In this work, we derive and discuss a statistical measure that reliably classifies compounds across temperature regimes and material classes by their "degree of anharmonicity". This enables us to distinguish "harmonic" materials, for which anharmonic effects constitute a small perturbation on top of the harmonic approximation, from strongly "anharmonic" materials, for which anharmonic effects become significant or even dominant and the treatment of anharmonicity in terms of perturbation theory is more than questionable. We show that the analysis of this measure in real and reciprocal space is able to shed light on the underlying microscopic mechanisms, even at conditions close to, e.g., phase transitions or defect formation. Eventually, we demonstrate that the developed approach is computationally efficient and enables rapid high-throughput searches by scanning over a set of several hundred binary solids. The results show that strong anharmonic effects beyond the perturbative limit are not only active in complex materials or close to phase transitions, but already at moderate temperatures in simple binary compounds.

description: We developed old designed of a Back-Propagation neural network (BPNN), which it was designed by other researchers, and we made modification in their structure. The 1st velocity ratio was discriminated by lowest speed, and highest twist. The 6th velocity ratio was discriminated by highest speed, and lowest twist. The aim of this paper is to design neural structure get best performance to control an electrical automotive transportation six-speed gearbox of the vehicle. We focus on the evaluation of the BPNN to select the suitable number of layers and neurons. Experimentally, the structure of the proposed BPNN are constructed from four layers: eight input nodes in the first layer that received data in binary number, 45 neurons in 1st hidden-layer, 25 neurons in 2nd hidden-layer, and 6 neurons in the fourth layer. The MSE and number of Epochs are the main factors used for the evaluation of the proposed structure, and compared with the other structures which was designed by other researchers. Experimentally, we discovered that the best value of Epoch and MSE was chosen when the BPNN consisted of two hidden-layers, 45, and 25 neurons in the 1st and 2nd hidden-layer respectively. The implementation was applied using MATLAB software.

description: We present temporal variations of the Si IV line profiles at the flare ribbons in three solar flares observed by the Interface Region Imaging Spectrograph (IRIS). In the M1.1 flare on 2014 September 6 and the X1.6 flare on 2014 September 10, the Si IV line profiles evolve from wholly redshifted to red-wing enhanced with the flare development. However, in the B1.8 flare on 2016 December 2, the Si IV line profiles are wholly redshifted throughout the flare evolution. We fit the wholly redshifted line profiles with a single Gaussian function but the red-asymmetric ones with a double Gaussian function to deduce the corresponding Doppler velocities. In addition, we find that hard X-ray emission above 25 keV shows up in the two large flares, implying a nonthermal electron beam heating. In the microflare, there only appears weak hard X-ray emission up to 12 keV, indicative of a thermal heating mostly. We interpret the redshifts or red asymmetries of the Si IV line at the ribbons in the three flares as spectral manifestations of chromospheric condensation. We propose that whether the line appears to be wholly redshifted or red-asymmetric depends on the heating mechanisms and also on the propagation of the condensation.

description: Error-bounded lossy compression is a state-of-the-art data reduction technique for HPC applications because it not only significantly reduces storage overhead but also can retain high fidelity for postanalysis. Because supercomputers and HPC applications are becoming heterogeneous using accelerator-based architectures, in particular GPUs, several development teams have recently released GPU versions of their lossy compressors. However, existing state-of-the-art GPU-based lossy compressors suffer from either low compression and decompression throughput or low compression quality. In this paper, we present an optimized GPU version, cuSZ, for one of the best error-bounded lossy compressors-SZ. To the best of our knowledge, cuSZ is the first error-bounded lossy compressor on GPUs for scientific data. Our contributions are fourfold. (1) We propose a dual-quantization scheme to entirely remove the data dependency in the prediction step of SZ such that this step can be performed very efficiently on GPUs. (2) We develop an efficient customized Huffman coding for the SZ compressor on GPUs. (3) We implement cuSZ using CUDA and optimize its performance by improving the utilization of GPU memory bandwidth. (4) We evaluate our cuSZ on five real-world HPC application datasets from the Scientific Data Reduction Benchmarks and compare it with other state-of-the-art methods on both CPUs and GPUs. Experiments show that our cuSZ improves SZ's compression throughput by up to 370.1x and 13.1x, respectively, over the production version running on single and multiple CPU cores, respectively, while getting the same quality of reconstructed data. It also improves the compression ratio by up to 3.48x on the tested data compared with another state-of-the-art GPU supported lossy compressor.

description: The dissipation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has already taken on pandemic proportions, affecting over 100 countries in a couple of weeks. The evolution of the disease and its economic impact is highly uncertain, which brings challenges for newly created software companies. Software startups are companies that create innovative software products and services in a dynamic and fast-growing market. Agile Software Methods aims to enable startups in responding to uncertainty caused by Covid-19. This paper investigates the impact of Covid-19 in a real software startup context to understand how they have reacted against uncertainties caused by Covid-19. As a research methodology, action research within Di2Win, a Brazilian software startup, has been applied. The study was carried out throughout six sprints, during the quarantine. Practices employed to mitigate threats while simultaneously allowing teams to remain open to opportunities and challenges are detailed. This paper shares lessons learned that could help agile software startups improve their way of work in an uncertain environment caused by the Covid-19 pandemic.

description: Photometric surveys with the Hubble Space Telescope (HST) allow us to study stellar populations with high resolution and deep coverage, with estimates of the physical parameters of the constituent stars being typically obtained by comparing the survey data with adequate stellar evolutionary models. This is a highly non-trivial task due to effects such as differential extinction, photometric errors, low filter coverage, or uncertainties in the stellar evolution calculations. These introduce degeneracies that are difficult to detect and break. To improve this situation, we introduce a novel deep learning approach, called conditional invertible neural network (cINN), to solve the inverse problem of predicting physical parameters from photometry on an individual star basis and to obtain the full posterior distributions. We build a carefully curated synthetic training data set derived from the PARSEC stellar evolution models to predict stellar age, initial/current mass, luminosity, effective temperature and surface gravity. We perform tests on synthetic data from the MIST and Dartmouth models, and benchmark our approach on HST data of two well-studied stellar clusters, Westerlund 2 and NGC 6397. For the synthetic data we find overall excellent performance, and note that age is the most difficult parameter to constrain. For the benchmark clusters we retrieve reasonable results and confirm previous findings for Westerlund 2 on cluster age ($1.04_{-0.90}^{+8.48}\,\mathrm{Myr} $), mass segregation, and the stellar initial mass function. For NGC 6397 we recover plausible estimates for masses, luminosities and temperatures, however, discrepancies between stellar evolution models and observations prevent an acceptable recovery of age for old stars.

description: A one-dimensional driven two-species model with parallel sublattice update and open boundaries is considered. Although the microscopic many-body dynamics is symmetric with respect to the two species and interactions are short-ranged, there is a region in parameter space with broken symmetry in the steady state. The sublattice update is deterministic in the bulk and allows for a detailed analysis of the relaxation dynamics, so that symmetry breaking can be shown to be the result of an amplification mechanism of fluctuations. In contrast to previously considered models, this leads to a proof for spontaneous symmetry breaking which is valid throughout the whole region in parameter space with a symmetry broken steady state.

description: The heat capacity of the solid Kr-CD4 (13% CD4) solution has been investigated. It is shown that the temperature dependence of the heat capacity Crot of the rotational subsystem in this solution is radically different from the corresponding dependences in the previously studied Kr-CD4 (1%, 5% CD4) and Kr-CH4 (5-60%) solutions. A model is proposed to explain the observed dependence Crot(T). The experimental results can be described taking into account the contribution to the heat capacity from CD4 molecules that are in weak, medium and strong molecular fields. The mean concentrations and energy differences between the ground and first excited energy levels of the CD4 molecules in these molecular fields have been estimated.
