description: GR and other metric theories of gravity are formulated with an arbitrary auxiliary curved background in a Lagrangian formalism. A new sketch of how to include spinor fields is included. Conserved quantities are obtained using Noether's theorem and expressed as divergences of antisymmetric densities, connecting local perturbations with quasi-local conserved quantities. The background's arbitrariness matches the so-called non-localizability of gravitational energy (infinity of localizations). The formalism has two partly overlapping uses: practical applications of pure GR (with fictitious background) and foundational considerations in which background causality facilitates quantization. The Schwarzschild solution is a primary application. Various possibilities for calculating the mass using surface integration are given. A field-theoretic curved spacetime is given from spatial infinity to the horizon and even to the true singularity. Trajectories of test particles in the Schwarzschild geometry are gauge-dependent in that even breakdowns at the horizon can be suppressed (or generated) by naive gauge transformations. This fact illustrates the auxiliary nature of the background metric and the need for some notion of maximal extension---much as with coordinate transformations in geometric GR. A continuous collapse to a point mass in the field-theoretic framework is given. The field-theoretic method is generalized to arbitrary metric theories in $D$ dimensions. The results are developed in the framework of Lovelock gravity and applied to calculate masses of Schwarzschild-like black holes. The bimetric formalism makes it natural to consider a graviton mass. Babak and Grishchuk's numerical and hence nonperturbative work sheds light on questions of a (dis)continuous massless limit for massive pure spin-2 and the classical (in)stability of spin-2/spin-0 theory.

description: We study the two-meson virtual cloud contribution to the self-energy of the SU(3) antidecuplet, to which the Theta+ pentaquark is assumed to belong. This is motivated by the large branching ratio of the N(1710) decay into two pions and one nucleon. We derive effective Lagrangians that describe the N(1710) decay into N-pi-pi with two pions in s or p wave. We obtain increased binding for all members of the antidecuplet and a contribution to the mass splitting between states with different strangeness which is at least 20 % of the empirical one. We also provide predictions for three-body decays of the pentaquark antidecuplet.

description: A new supersymmetric black hole solution of five-dimensional supergravity is presented. It has an event horizon of topology S1xS2. This is the first example of a supersymmetric, asymptotically flat black hole of non-spherical topology. The solution is uniquely specified by its electric charge and two independent angular momenta. These conserved charges can be arbitrarily close, but not exactly equal, to those of a supersymmetric black hole of spherical topology.

description: In this paper, we describe individual food consumption decisions as driven by a utility effect and a food environment effect. To outline the utility effect, we first develop a new theoretical model of individual food consumption. Next, we introduce the food environment effect by showing how the food environment can affect food consumption decisions and how this can skew the resulting food consumption vector. Finally, we analyse manipulations of the food environment as a potential form of policy intervention. Our key result is that the food environment has several entry points in food consumption decisions and that libertarian paternalistic manipulations of the food environment can be effective, easily implemented, well-accepted and low-cost intervention options to nudge individuals towards healthier food consumption. Thus, a first step in interventions meant to improve diets should always be to attend to the food environment: at the very least to “take off the heater” and ensure that the food environment does not inadvertently guide food consumption decisions in an undesirable direction.
Nonlinear dynamics of the interface of dielectric liquids in a strong electric field: Reduced equations of motion

description: The evolution of the interface between two ideal dielectric liquids in a strong vertical electric field is studied. It is found that a particular flow regime, for which the velocity potential and the electric field potential are linearly dependent functions, is possible if the ratio of the permittivities of liquids is inversely proportional to the ratio of their densities. The corresponding reduced equations for interface motion are derived. In the limit of small density ratio, these equations coincide with the well-known equations describing the Laplacian growth.

For every class of morphisms satisfying a mild smallness condition we prove the corresponding approximate-injectivity class is weakly reflective, and we study the properties of the reflection morphisms. As an application we present a new categorical proof of the essential uniqueness of the Gurarii space.

description: In the abelian sandpile model, recurrent chip configurations are of interest as they are a natural choice of coset representatives under the quotient of the reduced Laplacian. We investigate graphs whose recurrent identities with respect to different sinks are compatible with each other. The maximal stable configuration is the simplest recurrent chip configuration, and graphs whose recurrent identities equal the maximal stable configuration are of particular interest, and are said to have the complete maximal identity property. We prove that given any graph $G$ one can attach trees to the vertices of $G$ to yield a graph with the complete maximal identity property. We conclude with several intriguing conjectures about the complete maximal identity property of various graph products.

description: © 2020 American Chemical Society. All rights reserved. This Perspective of the published essential medicinal chemistry of cannabidiol (CBD) provides evidence that the popularization of CBD-fortified or CBD-labeled health products and CBD-associated health claims lacks a rigorous scientific foundation. CBD's reputation as a cure-all puts it in the same class as other "natural" panaceas, where valid ethnobotanicals are reduced to single, purportedly active ingredients. Such reductionist approaches oversimplify useful, chemically complex mixtures in an attempt to rationalize the commercial utility of natural compounds and exploit the "natural" label. Literature evidence associates CBD with certain semiubiquitous, broadly screened, primarily plant-based substances of undocumented purity that interfere with bioassays and have a low likelihood of becoming therapeutic agents. Widespread health challenges and pandemic crises such as SARS-CoV-2 create circumstances under which scientists must be particularly vigilant about healing claims that lack solid foundational data. Herein, we offer a critical review of the published medicinal chemistry properties of CBD, as well as precise definitions of CBD-containing substances and products, distilled to reveal the essential factors that impact its development as a therapeutic agent.
Universal scaling of electrostatic effects of a curved counter-electrode on the emitter field enhancement

description: Experiments on field electron emission from single-tip nanoemitters have typically been carried out using a counter-electrode with a finite curvature radius $R$, positioned at a distance $d_{\rm{gap}}$ from the emitter's apex. The effects of the counter-electrode's curvature on the apex field enhancement factor ($γ_{\rm{Ca}}$) of the emitter are still not understood. In this Letter, we theoretically explore how the apex field enhancement factor of an emitter, represented by a hemisphere on a cylindrical post (HCP) with apex radius $r_{\rm{a}} = 50$nm, is influenced by the curvature of a spherical-shaped counter-electrode. Importantly, our results show that for HCPs with sharpness aspect ratios typically between $10^2$ and $10^3$, there is a universal scaling such that $γ_{\rm{Ca}} = γ_{\rm{Pa}} Ψ\left({R}/{d_{\rm{gap}}} \right)$, where $γ_{\rm{Pa}}$ represents the apex field enhancement factor for the emitter assuming a planar counter-electrode, and $Ψ\left({R}/{d_{\rm{gap}}} \right)$ is a universal scaling function such that $Ψ\sim 1$ for ${R}/{d_{\rm{gap}}} \gg 1$ and $Ψ\sim \left({R}/{d_{\rm{gap}}} \right)^α$, with $α$ close to unity, for $ {R}/{d_{\rm{gap}}} \ll 1$. These findings help partially explain discrepancies observed in orhtodox field electron emission experiments, who reported that the effective $γ_{\rm{Ca}}$ values extracted from the current-voltage characteristics of single-tip carbon nanotubes typically underestimate the theoretical $γ_{\rm{Pa}}$ values when $R \sim d_{\rm{gap}} \gg r_{\rm{a}}$, a trend that is predicted by our results.

description: For a broad class of nonlinear regression models we investigate the local E- and c-optimal design problem. It is demonstrated that in many cases the optimal designs with respect to these optimality criteria are supported at the Chebyshev points, which are the local extrema of the equi-oscillating best approximation of the function f_0\equiv 0 by a normalized linear combination of the regression functions in the corresponding linearized model. The class of models includes rational, logistic and exponential models and for the rational regression models the E- and c-optimal design problem is solved explicitly in many cases.

Vessel size imaging of the Shionogi tumour model using contrast enhanced MRI
Creators: name: Wade, Trevor Paul
Publisher: name: University of British Columbia
Year: 2009

description: Vessel size imaging is a relatively new technique in Magnetic Resonance Imaging. By measuring the change in the transverse relaxation constants R₂ and R*₂ caused by the injection of a superparamagnetic contrast agent known as ferumoxtran, it is possible to create a map of vessel size index, which is a weighted average of the vessel radius. This technique was used on the Shionogi tumour model to monitor changes in vasculature as a result of androgen ablation by way of castration. A vessel size index map was created for androgen dependent, regressing and androgen independent tumours, and a statistically significant difference between the stages was found. Regressing tumours had the smallest vessel size index followed by androgen dependent and then androgen independent tumours. In addition, a qualitative comparison with Hoechst stained tumours was made.

description: Inappropriate diets have been found to cause long-term health problems in most industrial and post-industrial countries worldwide. Despite the existence of dietary guidelines in many countries – and widespread familiarity with these guidelines – large shares of the populations do not comply with these guidelines. The objective of the paper is to investigate economic explanations for non-compliance quantitatively, focusing on consumers’ perceived value of reduced freedom of choice, if they should comply with the dietary recommendations. The paper establishes and econometric simulation model for Danish food consumers, which is used for calculating these economic welfare losses, as well as the contribution to these losses from individual recommendations. Results show that if all the official dietary guidelines should be followed, consumers will experience an average perceived welfare loss, which in monetary terms correspond to 10-20 per cent of the food budget. There is some variation across the population, and substantial share of the consumers face a welfare loss below 10 per cent of the food budget. Recommendations on the intake of fruits, vegetables and seafood are found to be most binding.

description: This paper investigates whether information costs under currently regulated nutritional labeling prevent consumers from making healthier food choices. We implement five nutritional shelf label treatments in a market-level experiment. These labels reduce information costs by highlighting and summarizing information available on the Nutritional Facts Panel. Following a difference-in-differences and synthetic control method approach, we analyze weekly store-level scanner data for microwave popcorn purchases from treatment and control stores. Our results suggest that consumer purchases are affected by information costs. Implemented low calorie and no trans fat labels increase sales. In contrast, implemented low fat labels decrease sales, suggesting that consumer response is also influenced by consumers’ taste perceptions. A combination of these claims into one label treatment increases information costs and does not affect sales significantly.
Inductive limit algebras from periodic weighted shifts on Fock space

description: Non-commutative multivariable versions of weighted shift operators arise naturally as `weighted' left creation operators acting on the Fock space Hilbert space. We identify a natural notion of periodicity for these $N$-tuples, and then find a family of inductive limit algebras determined by the periodic weighted shifts which can be regarded as non-commutative multivariable generalizations of the Bunce-Deddens C*-algebras. We establish this by proving that the C*-algebras generated by shifts of a given period are isomorphic to full matrix algebras over Cuntz-Toeplitz algebras. This leads to an isomorphism theorem which parallels the Bunce-Deddens and UHF classification scheme.

We introduce them in the analysis of behaviours of participants in their food decisions (purchase intent, willingness to pay, reaction to new information), and underline some significant links.

description: A single solid tumor, composed of nearly identical cells, exhibits heterogeneous dynamics. Cells dynamics in the core is glass-like whereas those in the periphery undergo diffusive or super-diffusive behavior. Quantification of heterogeneity using the mean square displacement or the self-intermediate scattering function, which involves averaging over the cell population, hides the complexity of the collective movement. Using the t-distributed stochastic neighbor embedding (t-SNE), a popular unsupervised machine learning dimensionality reduction technique, we show that the phase space structure of an evolving colony of cells, driven by cell division and apoptosis, partitions into nearly disjoint sets composed principally of core and periphery cells. The non-equilibrium phase separation is driven by the differences in the persistence of self-generated active forces induced by cell division. Extensive heterogeneity revealed by t-SNE paves way towards understanding the origins of intratumor heterogeneity using experimental imaging data.

description: We overview recent changes in the ROOT I/O system, increasing performance and enhancing it and improving its interaction with other data analysis ecosystems. Both the newly introduced compression algorithms, the much faster bulk I/O data path, and a few additional techniques have the potential to significantly to improve experiment's software performance. The need for efficient lossless data compression has grown significantly as the amount of HEP data collected, transmitted, and stored has dramatically increased during the LHC era. While compression reduces storage space and, potentially, I/O bandwidth usage, it should not be applied blindly: there are significant trade-offs between the increased CPU cost for reading and writing files and the reduce storage space.

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

description: We present an analysis of the submillimetre/X-ray properties of 19 X-ray absorbed, Compton-thin quasi-stellar objects (QSOs) selected to have luminosities and redshifts which represent the peak of cosmic QSO activity. i.e. ~L* objects at 11.5, the high star formation rates are consistent with a scenario in which the QSOs evolve to become local luminous elliptical galaxies. Combining these results with previously published data for X-ray unabsorbed QSOs and submillimetre-selected galaxies we propose the following evolutionary sequence: the forming galaxy is initially far-infrared luminous but X-ray weak similar to the sources discovered by the Submillimetre Common-User Bolometer Array; as the black hole and spheroid grow with time a point is reached when the central QSO becomes powerful enough to terminate the star formation and eject the bulk of the fuel supply (the Compton-thin absorbed QSO phase); this transition is followed by a period of unobscured QSO activity which subsequently declines to leave a quiescent spheroidal galaxy.

Adjustable Rotoverter (Fuel-free Energy Generator)
Creators: name: Khmelnik, Solomon
Publisher: name: Zenodo
Year: 2019

description: A project of an adjustable rotoverter as a fuelless energy source is proposed. The project used various additions to the existing rotovertors to ensure stable operation under variable load. Theoretical proof of its performance is given. In fact, two facts are uniformly proved: 1) the rotoverter generates energy, 2) the planets rotate around its axis. No one has long argued with the second fact, but there is no other scientific explanation. The author invites partners for joint patenting on attractive terms.

description: In this paper we study the sensitivity of the flux of atmospheric muons to uncertainties in the primary cosmic ray spectrum and to the treatment of the geomagnetic field in a calculation. We use the air shower simulation program AIRES to make the calculation for two different primary spectra and under several approximations to the propagation of charged particles in the geomagnetic field. The results illustrate the importance of accurate modelling of the geomagnetic field effects. We propose a high and a low fit of the proton and helium fluxes, and calculate the muon fluxes with these different inputs. Comparison with measurements of the muon flux by the CAPRICE experiment shows a slight preference for the higher primary cosmic ray flux parametrization.

description: In this paper, we propose the use of traditional animations, heuristic behavior and reinforcement learning in the creation of intelligent characters for computational media. The traditional animation and heuristic gives artistic control over the behavior while the reinforcement learning adds generalization. The use case presented is a dog character with a high-level controller in a 3D environment which is built around the desired behaviors to be learned, such as fetching an item. As the development of the environment is the key for learning, further analysis is conducted of how to build those learning environments, the effects of environment and agent modeling choices, training procedures and generalization of the learned behavior. This analysis builds insight of the aforementioned factors and may serve as guide in the development of environments in general.

description: Applying a continuous-time quantum Monte-Carlo algorithm we calculate the exact coherent band dispersion and the density of states of a two dimensional lattice polaron in the region of parameters where any approximation might fail. We find an isotope effect on the band structure, which is different for different wave-vectors of the Brillouin zone and depends on the radius and strength of the electron-phonon interaction. An isotope effect on the electron spectral function is also discussed.

An angle-resolved photoemission spectroscopy study of T1₂Ba₂ CuO₆+[delta]
Creators: name: Mottershead, Jeffrey Daniel Frederick
Publisher: name: University of British Columbia
Year: 2009

description: Recent angle-resolved photoemission spectroscopy (ARPES) results on the high-temperature superconductor (HTSC) Tl₂Ba₂CuO₄+[sub Δ] (T12201) are presented. A very overdoped sample with a T[sub c] of 30 K was found to have a Fermi surface consisting of a large hole pocket centered at (Π,Π), which is approaching a topological transition. A superconducting gap consistent with a d[sub x[sup 2]-y[sup 2]] order parameter was detected. In contrast with the underdoped HTSCs, where the quasiparticle (QP) linewidth at the top of the band is maximal in the antinodal direction and minimal in the nodal direction, overdoped T12201 was revealed to have a reverse nodal/antinodal anisotropy, with sharp QP peaks in the antinodal region and broader peaks in the antinodal region. The T12201 results establish T12201 as a valuable material for exploring the overdoped side of the phase diagram with ARPES. They also raise numerous questions that demand further ARPES measurements over a broader range of dopings, as well as temperature-dependent measurements. In parallel with the T12201 research, a new in-house ARPES system is being constructed at University of British Columbia (UBC). The ARPES system under construction at UBC incorporates a molecular beam epitaxy (MBE) system for the growth of a much broader range of materials than can typically be studied by ARPES. Novel design techniques to improve the accuracy of ARPES measurements are presented.

description: To determine the efficiency of health-related endorsements in influencing consumer choice we report findings from two separate, unique discrete choice experiments (DCEs) involving fresh packaged beef steaks and seafood. In addition to quality and production-related attributes, the beef and seafood products also displayed a health endorsement: the Australian National Heart Foundation “Pick the Tick” certification. Another, more recently introduced health claim, “2 Serves a Week” was also included in the seafood experiment. Consumer awareness of the “Pick the Tick” certification was higher than any other extrinsic claim considered in the experiments. Furthermore, in both experiments, “Pick the Tick” had the highest impact and value relative to other extrinsic product cues, however, its impact on consumers’ choices was relatively low compared to intrinsic product characteristics and price. In both experiments, two segments of consumers: health-concerned consumers and premium-oriented consumers were more likely to value and use the “Pick the Tick” health-endorsement. The insignificance of the relatively new “2 Serves a Week” health claim in the analysis of the seafood experiment suggests that the simple addition of a food health claim alone will not impact consumer choice. Rather, food health endorsement programs require credible third-party certifiers as well as considerable investment in promotion before consumers become aware, trust and use them to guide food choices.

description: As the public expenditure for the Supplemental Nutrition Assistance Program (SNAP) - formerly the Food Stamp Program (FSP) - increases, improving the effectiveness of the policy becomes pivotal to limit further surges in public spending. Along with social stigma, transaction costs, associated in part to the accessibility and proximity to food outlets, are the main deterrent to program participation. This study presents an empirical assessment of the relationship between food access and FSP participation among eligible population. The analysis uses county-level data for the continental U.S., distinguished by different stores formats (grocery stores, convenience stores and a non-traditional, low-priced alternative, Wal-Mart Supercenters) accounting for the endogeneity of their location decision. To estimate the parameter of the model we use a relatively novel estimator: the spatial generalized two-stage least square (GS2SLS) estimator with heteroskedastic autoregressive disturbances of order (1,1) or SARAR(1,1), developed by Kelejian and Prucha (2010). Empirical results show that, among eligible individuals, the presence of small convenience stores, large grocery stores, and Walmart supercenters entice participation in the food stamp program. In sum, increasing the number of stores for which commuting by car is not strictly necessary (convenience stores) or the proximity to stores with wider assortment of low-priced items may act as catalysts to ability to the policy ability to reach the underprivileged.

description: Cosmic-ray acceleration processes in astrophysical plasmas are often investigated with fully-kinetic or hybrid kinetic numerical simulations, which enable us to describe a detailed microphysics of particle energization mechanisms. Tracing of individual particles in such simulations is especially useful in this regard. However, visually inspecting particle trajectories introduces a significant amount of bias and uncertainty, making it challenging to pinpoint specific acceleration mechanisms. Here, we present a novel approach utilising neural networks to assist in the analysis of individual particle data. We demonstrate the effectiveness of this approach using the dataset from our recent particle-in-cell (PIC) simulations of non-relativistic perpendicular shocks that consists of 252,000 electrons, each characterised by their position, momentum and electromagnetic field at particle's position, recorded in a time series of 1200 time steps. These electrons cross a region affected by the electrostatic Buneman instability, and a small percentage of them attain high energies. We perform classification, regression, and anomaly detection algorithms on the dataset by using a convolutional neural network, a multi-layer perceptron, and an autoencoder. Despite the noisy and imbalanced dataset, all methods demonstrate the capability to differentiate between thermal and accelerated electrons with remarkable accuracy. The proposed methodology may considerably simplify particle classification in large-scale PIC and hybrid simulations.

description: Factorial designs have broad applications in agricultural, engineering and scientific studies. In constructing and studying properties of factorial designs, traditional design theory treats all factors as nominal. However, this is not appropriate for experiments that involve quantitative factors. For designs with quantitative factors, level permutation of one or more factors in a design matrix could result in different geometric structures, and, thus, different design properties. In this paper indicator functions are introduced to represent factorial designs. A polynomial form of indicator functions is used to characterize the geometric structure of those designs. Geometric isomorphism is defined for classifying designs with quantitative factors. Based on indicator functions, a new aberration criteria is proposed and some minimum aberration designs are presented.

description: Superconducting quantum circuits are typically operated at low temperatures (mK), necessitating cryogenic low-noise, wide-band amplifiers for signal readout ultimately also compatible with room temperature electronics. While existing implementations partly meet these criteria, they suffer from certain limitations, such as rippled transmission spectra or limited dynamic range, some of which are caused by the lack of proper impedance matching. We develop a MIcrostrip Kinetic Inductance Travelling Wave Amplifier (MI-KITWA), exploiting the nonlinear kinetic inductance of tungsten-silicide for wave-mixing of the signal and a pump, and engineer the impedance to $50 Ω$, while decreasing the phase velocity, with benefit for the amplification. Despite losses, pumping on our device amplifies the signal by 15 dB over a 2 GHz bandwidth.

Super-Eddington accretion rates in Narrow Line Seyfert 1 galaxies

description: Using the BH masses deduced from the empirical relation of Kaspi et al. (2000) and assuming that the optical luminosity is provided by the accretion disc, we show that Narrow Line Seyfert Galaxies 1 (NLS1s) accrete at super-Eddington rates, while their luminosity stays of the order of the Eddington limit. We take into account the possibility of a non-viscous energy release in the gravitationally unstable region of the disc. It leads to a smaller accretion rate and to a redder continuum than a standard disc, which agrees better with the observations. The observed bolometric luminosities appear to saturate at a few times the Eddington luminosity for super-Eddington accretion rates, as predicted by slim disc models. The accretion rate stays always of the order of a few M$_{\odot}$/yr, indicating that the growing of the BH is mass supply limited . Since the masses of the BH increases by one order of magnitude in a few 10$^7$ years, it could explain why NLS1s appear to not follow the same BH - bulge relation as other galaxies. NLS1s should thus play an important role in shaping the mass function of local BHs. We discuss the possibility that the masses could be systematically underestimated due to an inclination effect, and we conclude that the accretion rates could thus be strongly overestimated, but only in a small proportion of objects.
