description: We use recent measurements of the dimensionless coordinate distances from Fanaroff-Riley Type IIb radio galaxies and the X-ray gas mass fractions in clusters to constrain the parameters of a non-standard cosmological model. This work complements our recent analysis of the SN Ia data within a non-Riemannian cosmological model. We use two independent data sets to constrain the new density parameter $Ω_ψ$, which is related to the non-Riemannian structure of the underlying spacetime and supplements the field equations that are very similar to the usual Friedmann equations of general relativity. Thereby we place an upper limit on the presence of non-Riemannian quantities in the late stages of the universe. The numerical results of this work also apply to several anisotropic cosmological models which, on the level of the field equations, exhibit a similar scaling behavior of the density parameters like our non-Riemannian model.

description: The purpose of this research was to determine whether indirect land use occurs and if so to what extent. Indirect land use is a change from non-cropland to cropland (e.g. deforestation) that may occur in response to increasing scarcity of cropland. As farmers worldwide respond to higher crop prices in order to maintain the global food supply and demand balance, pristine lands are cleared and converted to new cropland to replace the crops for feed and food that were diverted elsewhere to biofuels production. We examine the impact of corn-based ethanol production in the United States on land use in other countries.

description: Actual Production History (APH) yields play a critical role in determining the coverage offered to producers by the Risk Management Agency’s (RMA) Yield Protection, Revenue Protection, and Revenue Protection-Harvest Price Exclusion crop insurance products. The RMA currently uses the simple average of from 4 to 10 years of historical yields to determine the APH yield guarantee. If crop yields are trending upward, use of a simple average of historical yields introduces bias into the insurance offering. Using both county and individual insured unit data, we examine the producer impact of APH yield trends for Texas cotton and Illinois corn. Our findings indicate that biases due to using simple average APH yields when yields are trending upward reduce the expected indemnity and actuarially fair premium rate. Certainty equivalent differences are computed and used as a measure of the magnitude of welfare effect of trend-based biases in APH yields. The estimated welfare effect also varies significantly with different commonly used detrending approaches. This study demonstrates that producer welfare can be enhanced through proper treatment of yield trends in crop insurance programs.

description: We examine the recently-reported low-energy electron recoil spectrum observed at the XENON1T underground dark matter direct detection experiment, in the context of new interactions with solar neutrinos. In particular we show that scalar and vector mediators with masses $\lesssim 50$ keV coupled to leptons could already leave a visible signature in the XENON1T experiment, similar to the observed peak below 7 keV. This signals that dark matter detectors are already competing with neutrino scattering experiments such as GEMMA, CHARM-II and Borexino. If these results from XENON1T are interpreted as a new signal of such physics, the parameters which fit the excess face challenges from astrophysics which seem very difficult to overcome. If they are rather viewed as a constraint on new couplings, they herald the start of an era of novel precise probes of physics beyond the standard model with dark matter detectors.

Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: We propose to use a 13 KeV antiproton beam passing through a dense cloud of positronium (Ps) atoms to produce an H+ beam. These ions can be slowed down and captured by a trap. The process involves two reactions with large cross sections under the same experimental conditions. These reactions are the interaction of p with PS to produce H and the e+ capture by H reacting on PS to produce H+. Once decelerated with an electrostatic field and captured in a trap the H+ ions could be cooled and the e+ removed with a laser to perform a measurement of the gravitational acceleration of neutral antimatter in the gravity field of the Earth.

description: The emergence of video applications and video capable devices have contributed substantially to the increase of video traffic on Internet. New mechanisms recommending video rate adaptation towards delivering enhanced Quality of Experience (QoE) at the same time making room for more sessions. This paper introduces a cross-layer QoE-aware architecture for video traffic over the Internet. It proposes that video sources at the application layer adapt their rate to the network environment by controlling their transmitted bit rate dynamically; and the edge of network at the network layer protects the quality of the active video sessions by controlling the acceptance of new session through a video-aware admission control. In particular, it will seek the most efficient way of accepting new video session and adapting transmission rates to free up resources for more session while maintaining the QoE of active sessions. The proposed framework will contribute to the preparation for the extreme growth of video traffic in the foreseeable future. Simulation results show that the proposed cross-layer architecture guarantees the QoE for the admitted sessions and utilizes the link more efficiently comparing to the rate adaptation only architecture.

description: Die Cells + Tissuebank Austria gemeinnützige GmbH beschäftigt sich mit Entnahme, Aufbereitung und Verteilung von allogenen Transplantaten humanen Ursprungs. Der Schwerpunkt der Entnahmetätigkeit liegt im Bereich Hüftköpfe, welche von Lebendspen- derInnen - im Zuge von endoprothetischen Operationen - entnommen werden. Weiters wird Knochengewebe von OrganspenderInnen gewonnen. Diese Gewebe werden nach erfolg-ter Testung am Produktionsstandort aufbereitet. Dieser Prozess erfordert hohe Hygiene- und Sicherheitsstandards, welche in der Architektur einer neuen Produktionsstätte berücksichtigt werden müssen. Da es sich bei den Allografts um hochsensibles Material handelt, ist ein reibungsloser logistischer Ablauf mit möglichst effizienten Nahtstellen erforderlich: Temperatur, Feuchtigkeit, direktes Sonnenlicht, Stromausfälle und andere Umweltfaktoren können die Qualität des Spendermaterials erheblich beeinflussen. Ist es möglich, die bestehenden Raumstrukturen architektonisch derart zu transponieren, dass sie den gestellten Anforderungen gerecht werden und in weiterer Folge entsprechend dem schnellen Wachstum des Unternehmens - leicht adaptiert und erweitert werden können? Ist es möglich, diese räumliche Expansion programmatisch so aufzunehmen, dass dadurch nur kurze oder keine Produktionsausfälle entstehen? Kann ein neues, innovatives architektonisches Konzept bezüglich Labor- und Büroarbeit entwickelt werden, das diesem außergwöhnlichen Tätigkeitsfeld entspricht?
description: Cells + Tissuebank Austria gemeinnützige GmbH deals with the procurement, preparation and distribution of allogenic grafts of human origin. The focus of the removal activity is in the area of femoral heads, which are removed by living donors - in the course of endoprosthetic operations. Bone tissue is also obtained from organ donors. After testing, these tissues are processed at the production site. This process requires high hygiene and safety standards, which must be taken into account in the architecture of a new production facility. Since the allografts are highly sensitive material, a smart logistical process with the most efficient possible seams is required: temperature, humidity, direct sunlight, power failures and other environmental factors can significantly influence the quality of the donor material. Is it possible to architecturally transpose the existing spatial structures in such a way that they meet the requirements and can subsequently be easily adapted and expanded in accordance with the rapid growth of the company? Is it possible to program this spatial expansion in such a way that there are only short or no production downtimes? Can a new, innovative architectural concept regarding laboratory and office work be developed that corresponds to this exceptional field of activity?

description: In this study, we apply directed acyclic graphs and search algorithm designed for time series with non-Gaussian distribution to obtain causal structure of innovations from an error correction model. The structure of interdependencies among six international stock markets is investigated. The results provide positive empirical evidence that there exist long-run equilibrium and contemporaneous causal structure among these stock markets. DAG analysis results show that Hong Kong is influenced by all other open markets in contemporaneous time, whereas Shanghai is not influenced by any of the other markets in contemporaneous time. Historical decompositions indicate that New York and Shanghai stock markets are highly exogenous and Germany and Hong Kong are the least exogenous markets. Further, we find that New York is the most influential stock market with consistent impact on price movements. One implication is that diversification between US and Germany may not provide desired immunity from financial crisis contagion as much as it does diversification between US and Shanghai.

description: Institutions should reduce uncertainty and the costs of transaction with their regulating activities. This target was pursued at an international level with the foundation of the WTO. With an extensive treaty and a new dispute settlement procedure, the WTO was founded as the institutional platform for international co-operation. In view of the growing conflicts in international trade, the hope to create with this institution an international trade order, in which legally comprehensible decisions dominate and power-oriented politics are deterred, is fading. The case of the hormone dispute shows that the target of a fast harmonization of international standards cannot be reached in critical trade disputes. A solo effort in the area of trade measures that is introduced with the reason to protect consumers is still possible.

description: We continue our attempt to connect observational data on current helicity in solar active regions with solar dynamo models. In addition to our previous results about temporal and latitudinal distributions of current helicity (Kleeorin et al. 2003), we argue that some information concerning the radial profile of the current helicity averaged over time and latitude can be extracted from the available observations. The main feature of this distribution can be presented as follows. Both shallow and deep active regions demonstrate a clear dominance of one sign of current helicity in a given hemisphere during the whole cycle. Broadly speaking, current helicity has opposite polarities in the Northern and Southern hemispheres, although there are some active regions that violate this polarity rule. The relative number of active regions violating the polarity rule is significantly higher for deeper active regions. A separation of active regions into `shallow', `middle' and `deep' is made by comparing their rotation rate and the helioseismic rotation law. We use a version of Parker's dynamo model in two spatial dimensions, that employs a nonlinearity based on magnetic helicity conservation arguments. The predictions of this model about the radial distribution of solar current helicity appear to be in remarkable agreement with the available observational data; in particular the relative volume occupied by the current helicity of "wrong" sign grows significantly with the depth.

description: Light detection and ranging (lidar) has long been used in various applications. Solid-state beam steering mechanisms are needed for robust lidar systems. Here we propose and demonstrate a lidar scheme called "Swept Source Lidar" that allows us to perform frequency-modulated continuous-wave (FMCW) ranging and nonmechanical beam steering simultaneously. Wavelength dispersive elements provide angular beam steering, while a laser frequency is continuously swept by a wideband swept source over its whole tuning bandwidth. Employing a tunable vertical-cavity surface-emitting laser and a 1-axis mechanical beam scanner, three-dimensional point cloud data has been obtained. Swept Source Lidar systems can be flexibly combined with various beam steering elements to realize full solid-state FMCW lidar systems.

description: We study magnetically stabilized nematic order for spin-one bosons in optical lattices. We show that the Zeeman field-driven quantum transitions between non-nematic Mott states and quantum spin nematic states in the weak hopping limit are in the universality class of the ferromagnetic XXZ (S=1/2) spin model. We further discuss these transitions as condensation of interacting magnons. The development of O(2) nematic order when external fields are applied corresponds to condensation of magnons, which breaks a U(1) symmetry. Microscopically, this results from a coherent superposition of two non-nematic states at each individual site. Nematic order and spin wave excitations around critical points are studied and critical behaviors are obtained in a dilute gas approximation. We also find that spin singlet states are unstable with respect to quadratic Zeeman effects and Ising nematic order appears in the presence of any finite quadratic Zeeman coupling. All discussions are carried out for states in three dimensional bipartite lattices.

description: Capturing images under extremely low-light conditions poses significant challenges for the standard camera pipeline. Images become too dark and too noisy, which makes traditional enhancement techniques almost impossible to apply. Recently, learning-based approaches have shown very promising results for this task since they have substantially more expressive capabilities to allow for improved quality. Motivated by these studies, in this paper, we aim to leverage burst photography to boost the performance and obtain much sharper and more accurate RGB images from extremely dark raw images. The backbone of our proposed framework is a novel coarse-to-fine network architecture that generates high-quality outputs progressively. The coarse network predicts a low-resolution, denoised raw image, which is then fed to the fine network to recover fine-scale details and realistic textures. To further reduce the noise level and improve the color accuracy, we extend this network to a permutation invariant structure so that it takes a burst of low-light images as input and merges information from multiple images at the feature-level. Our experiments demonstrate that our approach leads to perceptually more pleasing results than the state-of-the-art methods by producing more detailed and considerably higher quality images.

DR2 is the first release to go beyond the $\sim$18mag (10$σ$) limit of the Shallow Survey released in DR1, and includes portions of the sky at full survey depth that reach >21mag in $g$ and $r$ filters. The DR2 photometry has a precision as measured by internal reproducibility of 1% in $u$ and $v$, and 0.7% in $griz$. More than 21 000 deg$^2$ have data in some filters (at either Shallow or Main Survey depth) and over 7 000 deg$^2$ have deep Main Survey coverage in all six filters. Finally, about 18 000 deg$^2$ have Main Survey data in $i$ and $z$ filters, albeit not yet at full depth. The release contains over 120 000 images, as well as catalogues with over 500 million unique astrophysical objects and nearly 5 billion individual detections. It also contains cross-matches with a range of external catalogues such as Gaia DR2, Pan-STARRS1 DR1, GALEX GUVcat, 2MASS, and AllWISE, as well as spectroscopic surveys such as 2MRS, GALAH, 6dFGS, and 2dFLenS.

Through an online survey, this study examined whether animation influences cartogram effectiveness. Traditional static cartograms with inset maps were compared to interactive and non-interactive animated cartograms. Four cartogram reading tasks were tested for each cartogram. Participants were also asked to their impressions and emotional reactions. The results show that animation and interactive animation influence cartogram effectiveness, with differing results depending on the task type.

description: Atmospheres of evolved AGB stars are heavily affected by pulsation, dust formation and mass loss, and they can become very extended. Time series of observed high-resolution spectra proved to be a useful tool to study atmospheric dynamics throughout the outer layers of these pulsating red giants. Originating at various depths, different molecular spectral lines observed in the near-infrared can be used to probe gas velocities there for different phases during the lightcycle. Dynamic model atmospheres are needed to represent the complicated structures of Mira variables properly. An important aspect which should be reproduced by the models is the variation of line profiles due to the influence of gas velocities. Based on a dynamic model, synthetic spectra (containing CO and CN lines) were calculated, using an LTE radiative transfer code that includes velocity effects. It is shown that profiles of lines that sample different depths qualitatively reproduce the behaviour expected from observations.

description: With recent outbreaks of Elizabethkingia affecting the United States, it is important to further understand the method of action that this bacterium uses to infect patients. Given that Elizabethkingia is not regarded as a pathogen when found in nature, but has developed several advantages in antibiotic resistance, the sheer flexibility and variability of this organism to evade host immunity and pharmacological responses is cause for awe and alarm. Within this paper we will analyze the importance of Elizabethkingia as a pathogen, its proteophylogenetic importance as a carrier of B-lactamases and the further development of a B-lactamase library for the identification of these genes and proteins in future strains and other organisms.

description: In this paper we explore a time-depended SEIR model, in which the dynamics of the infection in four groups from a selected target group (population), divided according to the infection, are modeled by a system of nonlinear ordinary differential equations. Several basic parameters are involved in the model: coefficients of infection rate, incubation rate, recovery rate. The coefficients are adaptable to each specific infection, for each individual country, and depend on the measures to limit the spread of the infection and the effectiveness of the methods of treatment of the infected people in the respective country. If such coefficients are known, solving the nonlinear system is possible to be able to make some hypotheses for the development of the epidemic. This is the reason for using Bulgarian COVID-19 data to first of all, solve the so-called "inverse problem" and to find the parameters of the current situation. Reverse logic is initially used to determine the parameters of the model as a function of time, followed by computer solution of the problem. Namely, this means predicting the future behavior of these parameters, and finding (and as a consequence applying mass-scale measures, e.g., distancing, disinfection, limitation of public events), a suitable scenario for the change in the proportion of the numbers of the four studied groups in the future. In fact, based on these results we model the COVID-19 transmission dynamics in Bulgaria and make a two-week forecast for the numbers of new cases per day, active cases and recovered individuals. Such model, as we show, has been successful for prediction analysis in the Bulgarian situation. We also provide multiple examples of numerical experiments with visualization of the results.

Rotating massive stars: Pre-SN models and stellar yields at solar metallicity

description: We present a new set of stellar yields obtained from rotating stellar models at solar metallicity covering the massive star range (9-120 solar masses). The stellar models were calculated with the latest version of the Geneva stellar evolution code described in Hirschi et al 2004a. The contributions from stellar winds and from supernova explosions to the stellar yields were calculated separately. The two contributions were then added to compute the total stellar yields (Hirschi et al 2004b). The effects of rotation on pre-supernova models are significant between 15 and 30 solar masses. Above 20 solar masses, rotation may change the radius or colour of the supernova progenitors (blue instead of red supergiant) and the supernova type (IIb or Ib instead of II). Rotation increases the helium and CO core sizes by a factor about 1.5. Thus, rotation increases the total metallic yields and in particular the yields for carbon and oxygen by a factor 1.5-2.5. For Wolf-Rayet stars (M>30 solar masses), rotation increases the yields of helium and other hydrogen burning products but does not significantly affect the yields of heavy elements.

An economic analysis of sales flyer advertising frequency by competing grocery manufactures and supermarkets
Creators: name: Lung, Cary
Publisher: name: University of British Columbia

description: The advertising strategies of retailers competing for processed food and beverage product markets are studied by constructing a theoretical model and then testing the model's predictions using statistical analysis of primary data. The advertising decisions are jointly determined by the food manufacturers and food retailers. Categorical data consisting of yes-no advertising decisions for 22 processed food products was collected from the sales flyers of four major supermarket chains and was recorded in 2 X 2 contingency tables. The chi-square test for a 2 X 2 contingency table was then used to test the hypotheses concerning yes-no advertising decisions for a particular product in three pairs of competing supermarkets, and for different brands of a common product by two competing manufacturers within a particular supermarket. In the second category four scenarios were considered: (1) a chosen brand versus the private label, (2) a chosen brand versus any national brand other than the chosen brand, (3) any national brand versus the private label, and (4) the private label of one supermarket versus the private label of another supermarket. The results show overwhelming support for the hypothesis that food manufacturers and retailers are randomly choosing which products to promote and when to promote them. For the within-store analyses, the advertising strategies for national brands and private label products are independent in most cases. Results show that there is a negative correlation for those few cases that are statistically dependent, apparently that the food companies are choosing to advertise different brands in a given period to avoid intensive competition. However, in the supermarket selling a large volume of products with private labels, there is a positive correlation for those cases that are dependent. The retailer is evidently advertising both the national brand and the private label to promote the private label products as substitutes for the national brand products.

description: We reconsider transport experiments in strongly anisotropic superconducting cuprates and we find that universal Aslamazov-Larkin (AL) paraconductivity in two dimensions is surprisingly robust even in the underdoped regime below the pseudogap crossover temperature T^*. We also establish that the underlying normal state resistivity in the pseudogap phase is (almost) linear in temperature, with all the deviations being quantitatively accounted by AL paraconductivity. The disappearence of paraconductivity is governed by the disappearence of gaussian pair fluctuations at an energy scale related to T^*.

description: Quantum emitters in hexagonal Boron Nitride (hBN) were recently reported to hol a homogeneous linewidth according to the Fourier-Transform limit up to room temperature. This unusual observation was traced back to decoupling from in-plane phonon modes which can arise if the emitter is located between two planes of the hBN host material. In this work, we investigate the origins for the mechanical decoupling. Improved sample preparation enabled a reduced background and a 70-fold decrease of spectral diffusion which was so far the major drawback of defect center in hBN and allowed us to reveal a gap in the electron-phonon spectral density for low phonon frequencies. This decoupling from phonons persists at room temperature and explains the observed Fourier Transform limited lines up to 300K. Furthermore, we investigate the dipole emission directionality and show a preferred photon emission through the side of the hBN flakes supporting the claim for an out-of-plane distortion of the defect center. Our work lays the foundation to a deeper understanding of the underlying physics for the persistence of Fourier-Transform limit lines up to room temperature. It furthermore provides a description on how to identify the mechanically isolated emitter within the large number of defect centers in hBN. Therefore, it paves the way for quantum optics applications with defect centers in hBN at room temperature.
