Alienation, equality, and multifaith establishment

description: Religious establishment today often takes a multifaith form, whereby multiple religions are supported in different ways and to different degrees. In order to contribute to the development of a normative framework for assessing practices and regimes of multifaith establishment, this article recommends the concept of “social alienation.” Initially, social alienation is defended as a negative normative criterion to determine when specific establishment practices are unacceptable. This criterion is compared favorably with approaches that evaluate establishment practices by reference to an ideal of public reason or according to whether they convey an expressive harm, as well as with similar approaches based on a purely subjective understanding of alienation. Subsequently, it is also argued that addressing social alienation can support a case for multifaith religious establishment regimes that support or recognize minority religions, since it is often unequal establishment practices that socially alienate, not establishment as such.

description: The doping and temperature dependent conductivity of electron-doped cuprates is analysed. The variation of kinetic energy with doping is shown to imply that the materials are approximately as strongly correlated as the hole-doped materials. The optical spectrum is fit to a quasiparticle scattering model; while the model fits the optical data well, gross inconsistencies with photoemission data are found, implying the presence of a large, strongly doping dependent Landau parameter.

description: Deep learning (DL) in remote sensing has nowadays become an effective operative tool: it is largely used in applications such as change detection, image restoration, segmentation, detection and classification. With reference to synthetic aperture radar (SAR) domain the application of DL techniques is not straightforward due to non trivial interpretation of SAR images, specially caused by the presence of speckle. Several deep learning solutions for SAR despeckling have been proposed in the last few years. Most of these solutions focus on the definition of different network architectures with similar cost functions not involving SAR image properties. In this paper, a convolutional neural network (CNN) with a multi-objective cost function taking care of spatial and statistical properties of the SAR image is proposed. This is achieved by the definition of a peculiar loss function obtained by the weighted combination of three different terms. Each of this term is dedicated mainly to one of the following SAR image characteristics: spatial details, speckle statistical properties and strong scatterers identification. Their combination allows to balance these effects. Moreover, a specifically designed architecture is proposed for effectively extract distinctive features within the considered framework. Experiments on simulated and real SAR images show the accuracy of the proposed method compared to the State-of-Art despeckling algorithms, both from quantitative and qualitative point of view. The importance of considering such SAR properties in the cost function is crucial for a correct noise rejection and details preservation in different underlined scenarios, such as homogeneous, heterogeneous and extremely heterogeneous.
Evaluation of the Salish Creek mitigation project

description: I investigated colonization patterns of coho salmon (Oncorhynchus kisutch), cutthroat trout (Oncorhynchus clarki), largemouth bass (Micropterus salmoides), and the endangered Salish sucker (Catostomus Sp) and Nooksack dace (Rhinichthys Sp.) into a newly constructed channel in a headwater stream in British Columbia's Fraser Valley over a one-and-a-half year period. Fish fence and mark-recapture data indicated that the study area was colonized by all species beyond the level found in the original channel in terms of numerical abundance indicating no net loss. The densities found in high quality natural habitat were not reached by the end of the study period. A total of 4897 fish entered and 710 exited the study area during the first year. Coho achieved highest numbers and densities in the shortest period followed by cutthroat trout and Salish sucker with few Nooksack dace entering or remaining. Colonization was greatest during the spring months for all species and from upstream and downstream sources. Coho salmon and cutthroat trout were mainly juveniles dispersing shortly after hatching in spring. Salish sucker colonizers were primarily spawning adults. The relatively small number of Salish sucker and Nooksack dace colonizers reflects their rareness, more restricted movements and, in the case of the dace, selectivity of the fences. Other than smolt migration, little coho movement occurred at temperatures below 9°C and most movement took place at temperatures from 10 to 15°C, roughly corresponding to preferred temperatures. Movement of cutthroat trout occurred at temperatures from 2°C to over 20°C. The majority of adult Salish suckers entered from Pepin Brook between temperatures of 4 to 10°C. Males outnumbered females by almost 3:1. The condition factor and growth rates of Salish sucker in the study area were significantly greater than those in mainstem habitat. Largemouth bass moved most often at temperatures above 17°C, consistent with life history characteristics. ANOVA did not reveal consistent statistical results of fish movement in relation to season, temperature and discharge. However, season, discharge and temperature were inter-correlated. The relatively short time frame of movement for the vast number of fishes reflects the need for appropriate physiological, developmental and/or reproductive states of the fish to coincide with appropriate stream conditions for movement to occur together with an attempt to colonize new, unexploited habitat.

description: With a rising need for transporting people from one place to another especially within urban spaces, many mobility-on-demand (MoD) systems like Uber, Lyft and the like have burgeoned to provide swift and efficient mobilty services within just a few taps through our smartphone devices. Although carpooling, an inherently fuelefficient concept, has penetrated into this market, commercial ride-sharing systems (e.g., Uber Pool, Lyft Line, etc.) do not perform the vehicle dispatch optimization in a fuel-efficient manner for the rider pick-up and drop-off phases of travel.
Moreover, present ride-sharing algorithms have a centralized computing back-bone – making online ride-sharing optimization problems compute heavy, and thereby once again energy inefficient. With the rising level of tailpipe CO2 emissions, it is prudent to focus on fuel efficiency to curb climate impact from warming.
Quantization of the canonically conjugate pair angle and orbital angular momentum

description: The question how to quantize a classical system where an angle phi is one of the basic canonical variables has been controversial since the early days of quantum mechanics. The problem is that the angle is a multivalued or discontinuous variable on the corresponding phase space. The remedy is to replace phi by the smooth periodic functions cos phi and sin phi. In the case of the canonical pair (phi,l),l: orbital angular momentum (OAM), the phase space S_(phi,l) ={phi in R mod 2pi, l in R} has the global structure S^1 x R of a cylinder on which the Poisson brackets of the 3 functions cos phi, sin phi and l obey the Lie algebra of the euclidean group E(2) in the plane. This property provides the basis for the quantization of the system in terms of irreducible unitary representations of the group E(2) or of its covering groups. A crucial point is that - due to the fact that the subgroup SO(2) = S^1 is multiply connected - these representations allow for fractional OAM l = n + c, c in [0,1). Such c not 0 have already been observed in cases like the Aharonov-Bohm and the fractional quantum Hall effects and they correspond to the quasi-momenta of Bloch waves in ideal crystals. The proposal of the present paper is to look for fractional OAM in connection with the quantum optics of Laguerre-Gaussian laser modes in external magnetic fields. The quantum theory of the phase space S_(phi,l) in terms of unitary representations of E(2) allows for two types of "coherent" states the properties of which are discussed in detail: Non-holomorphic minimal uncertainty states and holomorphic ones associated with Bargmann-Segal Hilbert spaces.

description: An analytical formula is derived for particle and energy densities of fermions and bosons, and their ballistic momentum and energy currents for anisotropic energy dispersions in generalized dimensions. The formulation considerably simplifies the comparison of the statistical properties and ballistic particle and energy transport currents of electrons, acoustic phonons, and photons in various dimensions in a unified manner. Assorted examples of its utility are discussed, ranging from blackbody radiation to Schottky diodes and ballistic transistors, quantized electrical and thermal conductance, generalized ballistic Seebeck and Peltier coefficients, their Onsager relations, the generalized Wiedemann-Franz law and the robustness of the Lorenz number, and ballistic thermoelectric power factors, all of which are obtained from the single formula. The new formulation predicts a thermoelectric power factor behaviour of 3D Dirac bands which has not been observed yet.

Why Buckling Stellar Bars Weaken in Disk Galaxies

Year: 2004

description: Young stellar bars in disk galaxies experience a vertical buckling instability which terminates their growth and thickens them, resulting in a characteristic peanut/boxy shape when viewed edge on. Using N-body simulations of galactic disks embedded in live halos, we have analyzed the bar structure throughout this instability and found that the outer third of the bar dissolves completely while the inner part (within the vertical inner Lindblad resonance) becomes less oval. The bar acquires the frequently observed peanut/boxy-shaped isophotes. We also find that the bar buckling is responsible for a mass injection above the plane, which is subsequently trapped by specific 3-D families of periodic orbits of particular shapes explaining the observed isophotes, in line with previous work. Using a 3-D orbit analysis and surfaces of sections, we infer that the outer part of the bar is dissolved by a rapidly widening stochastic region around its corotation radius -- a process related to the bar growth. This leads to a dramatic decrease in the bar size, decrease in the overall bar strength and a mild increase in its pattern speed, but is not expected to lead to a complete bar dissolution. The buckling instability appears primarily responsible for shortening the secular diffusion timescale to a dynamical one when building the boxy isophotes. The sufficiently long timescale of described evolution, ~1 Gyr, can affect the observed bar fraction in local universe and at higher redshifts, both through reduced bar strength and the absence of dust offset lanes in the bar.

description: This paper examines the possibility of introducing a composite material based on fiberglass and carbon fiber. A truss beam was taken as the model under study, in which all bracing elements were replaced with a composite. In total, the work considers three types of braces: braced, cross, and combined (a beam with a cantilever, where braced and cross types are used). All research was carried out using the Femap with Nastran program. The metal structure was calculated, and the design loads were found, and a table was compiled, on its basis a model was designed in RSTAB, and the crane was calculated using FEM. Based on the resulting values, economic efficiency was found.
Hidden symmetries in the asymmetric exclusion process

description: We present a spectral study of the evolution matrix of the totally asymmetric exclusion process on a ring at half filling. The natural symmetries (translation, charge conjugation combined with reflection) predict only two fold degeneracies. However, we have found that degeneracies of higher order also exist and, as the system size increases, higher and higher orders appear. These degeneracies become generic in the limit of very large systems. This behaviour can be explained by the Bethe Ansatz and suggests the presence of hidden symmetries in the model. Keywords: ASEP, Markov matrix, symmetries, spectral degeneracies, Bethe Ansatz.

Testing the effect of earplug use on sleep in critically ill patients
Creators: name: House, Michelle Anne Marie
Publisher: name: University of British Columbia
Year: 2009

description: A preliminary study was designed to assess the feasibility of testing the effect of earplug use, as a nursing intervention, on the sleep of critically ill patients using polysomnography. This study was done as a necessary first step in determining the feasibility of a larger, adequately powered study testing the same intervention as a cost-effective, non-invasive means of promoting sleep in the critically ill population. A single subject repeated measures design was used, and subjects served as their own controls. Two participants completed the study protocol. Analysis of the study data resulted in a number of recommendations for future studies. First, it was demonstrated that a larger study testing the effect of earplug use in critically ill adults is needed, and that it is feasible to conduct such a study i f sufficient funding is obtained. It is also suggested that the use of a research facilitator be considered to resolve some of the barriers encountered in recruitment of subjects, and to also overcome some of the logistical issues with nursing and medical support for the project. Access to interpretive services needs to be available for such a study to be successfully implemented in the same setting. It is further recommended that noise levels are measured concurrently with the polysomnographic sleep measurement. Planning for a future study must include careful consideration of eligibility criteria. Specifically, it is recommended that an upper limit of morphine equivalents of 30 micrograms per kilogram per hour be set. Finally, qualitative data regarding the participants' subjective experience of sleep should be collected to further inform the study.

description: The investigation of the generalized coherent states for oscillator-like systems connected with given family of orthogonal polynomials is continued. In this work we consider oscillators connected with Meixner and Meixner-Pollaczek polynomials and define generalized coherent states for these oscillators. The completeness condition for these states is proved by the solution of the related classical moment problem. The results are compared with the other authors ones. In particular, we show that the Hamiltonian of the relativistic model of linear harmonic oscillator can be thought of as the linearization of the quadratic Hamiltonian which naturally arised in our formalism.

description: Recently, we presented evidence for a cross-correlation of the WMAP satellite map of the cosmic microwave background (CMB) and the HEAO1 satellite map of the hard X-ray background (XRB) with a dimensionless amplitude of 0.14 +- 0.05 normalized to the product of the rms fluctuations of the CMB and XRB (Boughn & Crittenden, 2004). Such a correlation is expected in a universe dominated by a cosmological constant via the integrated Sachs-Wolfe (ISW) effect and the level of the correlation observed is consistent with that predicted by the currently favored Lambda cold dark matter model of the universe. Since this offers independent confirmation of the cosmological model, it is important to verify the origin of the correlation. Here we explore in detail some possible foreground sources of the correlation. The present evidence all supports an ISW origin.

Based on state-level data for 2005,demand in the Northeast and Midwest regions of the U.S. were found to be inelastic. This suggests that the market for poinsettias in both regions could support higher prices.

description: Excitons and trions (or exciton-polarons) in transition metal dichalcogenides (TMDs) are known to decay predominantly through intravalley transitions. Electron-hole recombination across different valleys can also play a significant role in the excitonic dynamics, but intervalley transitions are rarely observed in monolayer TMDs, because they violate the conservation of momentum. Here we reveal the intervalley recombination of dark excitons and trions through more than one path in monolayer WSe$_2$. We observe the intervalley dark excitons, which can recombine by the assistance of defect scattering or chiral-phonon emission. We also reveal that a trion can decay in two distinct paths - through intravalley or intervalley electron-hole recombination - into two different final valley states. Although these two paths are energy degenerate, we can distinguish them by lifting the valley degeneracy under a magnetic field. In addition, the intra- and inter-valley trion transitions are coupled to zone-center and zone-corner chiral phonons, respectively, to produce distinct phonon replicas. The observed multipath optical decays of dark excitons and trions provide much insight into the internal quantum structure of trions and the complex excitonic interactions with defects and chiral phonons in monolayer valley semiconductors.

description: Machine learning (ML) models benefit from large datasets. Collecting data in biomedical domains is costly and challenging, hence, combining datasets has become a common practice. However, datasets obtained under different conditions could present undesired site-specific variability. Data harmonization methods aim to remove site-specific variance while retaining biologically relevant information. This study evaluates the effectiveness of popularly used ComBat-based methods for harmonizing data in scenarios where the class balance is not equal across sites. We find that these methods struggle with data leakage issues. To overcome this problem, we propose a novel approach PrettYharmonize, designed to harmonize data by pretending the target labels. We validate our approach using controlled datasets designed to benchmark the utility of harmonization. Finally, using real-world MRI and clinical data, we compare leakage-prone methods with PrettYharmonize and show that it achieves comparable performance while avoiding data leakage, particularly in site-target-dependence scenarios.

description: Semi-analytic models (SAMs) are a promising means of tracking the physical processes associated with galaxy formation, but many of their approximations have not been rigorously tested. As part of the SMAUG (Simulating Multiscale Astrophysics to Understand Galaxies) project, we compare predictions from the FIRE-2 hydrodynamical "zoom-in" simulations to those from the Santa Cruz SAM run on the same halo merger trees, with an emphasis on the global mass flow cycle. Our study includes 13 halos spanning low-mass dwarfs (M_vir~10^10 M_sun at z=0), intermediate-mass dwarfs (M_vir~10^11 M_sun) and Milky Way-mass galaxies (M_vir~10^12 M_sun). The SAM and FIRE-2 predictions agree relatively well with each other in terms of stellar and interstellar mass, but differ dramatically on circumgalactic mass (the SAM is lower than FIRE-2 by ~3 orders of magnitude for dwarfs). Strikingly, the SAM predicts higher gas accretion rates for dwarfs compared to FIRE-2 by factors of ~10-100, and this is compensated for with higher mass outflow rates in the SAM. We argue that the most severe model discrepancies are caused by the lack of preventative stellar feedback and the assumptions for halo gas cooling and recycling in the SAM. As a first step towards resolving these model tensions, we present a simple yet promising new preventative stellar feedback model in which the energy carried by supernova-driven winds is allowed to heat some fraction of gas outside of halos to at least the virial temperature such that accretion is suppressed.

description: The 2005 – 2006 marketing campaign was difficult because of the drought that occurred in all countries in the region. As a result, the price of sorghum, millet, maize and rice soared. State actions to improve cereals supply through tax-exempt rice imports did not achieve the expected outcomes. Rice has been the main contributing factor to the rise of cereals price. The low levels of stocks of rice in the world and the supply in fertilizers below expectations along with a decrease in productivity have contributed to the rise of rice prices at the national level.

description: This work is motivated by the relation between the KP and BKP integrable hierarchies, whose $τ$-functions may be viewed as sections of dual determinantal and Pfaffian line bundles over infinite dimensional Grassmannians. In finite dimensions, we show how to relate the Cartan map which, for a vector space $V$ of dimension $N$, embeds the Grassmannian ${\mathrm {Gr}}^0_V(V+V^*)$ of maximal isotropic subspaces of $V+ V^*$, with respect to the natural scalar product, into the projectivization of the exterior space $Λ(V)$, and the Plücker map, which embeds the Grassmannian ${\mathrm {Gr}}_V(V+ V^*)$ of all $N$-planes in $V+ V^*$ into the projectivization of $Λ^N(V + V^*)$. The Plücker coordinates on ${\mathrm {Gr}}^0_V(V+V^*)$ are expressed bilinearly in terms of the Cartan coordinates, which are holomorphic sections of the dual Pfaffian line bundle ${\mathrm {Pf}}^* \rightarrow {\mathrm {Gr}}^0_V(V+V^*, Q)$. In terms of affine coordinates on the big cell, this is equivalent to an identity of Cauchy-Binet type, expressing the determinants of square submatrices of a skew symmetric $N \times N$ matrix as bilinear sums over the Pfaffians of their principal minors.

Towards a grounded theory of urban attached housing design for families : balancing lifestyle perceptions with sanctuary needs
Creators: name: Pander, Sean
Publisher: name: University of British Columbia
Year: 2009

description: As Canada becomes an increasingly urban nation, a growing number of people have begun to express concern over the social and environmental costs of suburban development. Despite these concerns, detached suburban housing remains the preferred form for most families. This research uses a qualitative approach to develop an improved understanding of the housing needs of second generation+ Canadian families with pre-school aged children. A home provides sanctuary, lifestyle opportunities, and is an important financial investment for young families today. This understanding of the needs behind family housing preferences made it possible to propose an emergent grounded theory of attached housing design. While it is essential to satisfy a family's sanctuary needs, it the rich public realm of a good urban environment that compensates for the loss of private space and would attract more young Canadian families to urban living. The three core findings of this research are: • families with an urban lifestyle vision are the most likely to perceive urban attached housing as an appealing alternative; • family housing should be concentrated on quiet streets close to vibrant community and retail amenities to enable this lifestyle; • satisfying a family's need for sanctuary through the provision of sufficient and appropriately laid-out interior space is key to increasing the appeal of attached housing alternatives.

description: We present spectral results, from Chandra and XMM-Newton observations, of a sample of 22 low-redshift (z < 0.1) radio galaxies, and consider whether the core emission originates from the base of a relativistic jet, an accretion flow, or contains contributions from both. We find correlations between the unabsorbed X-ray, radio, and optical fluxes and luminosities of FRI-type radio-galaxy cores, implying a common origin in the form of a jet. On the other hand, we find that the X-ray spectra of FRII-type radio-galaxy cores is dominated by absorbed emission, with $N_{\rm H} > 10^{23}$ atoms cm$^{-2}$, that is likely to originate in an accretion flow. We discuss several models which may account for the different nuclear properties of FRI- and FRII-type cores, and also demonstrate that both heavily obscured, accretion-related, and unobscured, jet-related components may be present in all radio-galaxy nuclei. Any absorbed, accretion-related, components in FRI-type galaxies have low radiative efficiencies.

description: Over the last few years two promising research directions in low-resource neural machine translation (NMT) have emerged. The first focuses on utilizing high-resource languages to improve the quality of low-resource languages via multilingual NMT. The second direction employs monolingual data with self-supervision to pre-train translation models, followed by fine-tuning on small amounts of supervised data. In this work, we join these two lines of research and demonstrate the efficacy of monolingual data with self-supervision in multilingual NMT. We offer three major results: (i) Using monolingual data significantly boosts the translation quality of low-resource languages in multilingual models. (ii) Self-supervision improves zero-shot translation quality in multilingual models. (iii) Leveraging monolingual data with self-supervision provides a viable path towards adding new languages to multilingual models, getting up to 33 BLEU on ro-en translation without any parallel data or back-translation.
Capacity Analysis for Continuous Alphabet Channels with Side Information, Part I: A General Framework

description: Capacity analysis for channels with side information at the receiver has been an active area of interest. This problem is well investigated for the case of finite alphabet channels. However, the results are not easily generalizable to the case of continuous alphabet channels due to analytic difficulties inherent with continuous alphabets. In the first part of this two-part paper, we address an analytical framework for capacity analysis of continuous alphabet channels with side information at the receiver. For this purpose, we establish novel necessary and sufficient conditions for weak* continuity and strict concavity of the mutual information. These conditions are used in investigating the existence and uniqueness of the capacity-achieving measures. Furthermore, we derive necessary and sufficient conditions that characterize the capacity value and the capacity-achieving measure for continuous alphabet channels with side information at the receiver.

description: To analyze compliance with one aspect of the regulation of stormwater discharge, we estimate a random-utility model of the probability that a builder uses a silt fence to control sediments on a lot with a house under construction in an urbanizing county of South Carolina. The probability increases if the builder is responsible to the subdivision’s developer or if a homeowners association exists. The probability also increases as the cost to install a silt fence decreases or the number of houses under construction per built house in a subdivision increases. The results can help county officials target inspection to improve compliance.
Determinantal Expressions in Multi-Species TASEP

Subjects: subject: Probability (math.PR)
subject: FOS: Mathematics

description: Consider an inhomogeneous multi-species TASEP with drift to the left, and define a height function which equals the maximum species number to the left of a lattice site. For each fixed time, the multi-point distributions of these height functions have a determinantal structure. In the homogeneous case and for certain initial conditions, the fluctuations of the height function converge to Gaussian random variables in the large-time limit. The proof utilizes a coupling between the multi-species TASEP and a coalescing random walk, and previously known results for coalescing random walks.

description: Dual-purpose winter wheat (fall-winter forage plus grain) production is an important economic enterprise in the southern Great Plains. Grazing termination to enable grain production is a critical decision. The objective is to determine the optimal grazing termination date for dual-purpose wheat. The value of knowing the occurrence of first hollow stem (FHS), a wheat growth threshold for grazing termination, is also determined. Results indicate that for most price situations grazing should be terminated at or before FHS. Marginal wheat returns from extended grazing were negative and the value of FHS information ranges from $1.50 to $10 per acre.

description: Monthly observations on prices from 10 weight/gender classifications of Nebraska beef cattle are studied in an error correction model (ECM) framework. This study attempts a replication of the 2003 paper on Texas prices by Bessler and Davis, where they find medium heifers (600–700 lb) at the center of price discovery. Using the ECM results Nebraska light steers are found to be weakly exogenous, with the innovation accounting results showing marked differences. Industry structure, production choices, and animal type and breeding herd differences between Texas and Nebraska are proposed as plausible reasons for partial (or incomplete) success at replication.
