description: Phase-contrast imaging is an emerging technology that may increase the signal-difference-to-noise ratio in medical imaging. One of the most promising phase-contrast techniques is Talbot interferometry, which, combined with energy-sensitive photon-counting detectors, enables spectral differential phase-contrast mammography. We have evaluated a realistic system based on this technique by cascaded-systems analysis and with a task-dependent ideal-observer detectability index as a figure-of-merit. Beam-propagation simulations were used for validation and illustration of the analytical framework. Differential phase contrast improved detectability compared to absorption contrast, in particular for fine tumor structures. This result was supported by images of human mastectomy samples that were acquired with a conventional detector. The optimal incident energy was higher in differential phase contrast than in absorption contrast when disregarding the setup design energy. Further, optimal weighting of the transmitted spectrum was found to have a weaker energy dependence than for absorption contrast. Taking the design energy into account yielded a superimposed maximum on both detectability as a function of incident energy, and on optimal weighting. Spectral material decomposition was not facilitated by phase contrast, but phase information may be used instead of spectral information.

description: This research model examines the use of FAPRI baselines and ranges to develop marketing strategies for the sale of corn and soybeans. The goal was to create a disciplined and objective approach for selling crop which would ultimately increase prices received over the 2008-2018 10-year period. Three strategies were developed: A Price Objective strategy which makes upside sales, a Trailing Stop strategy which makes downside sales, and a Seasonal Sale strategy which makes structured sales during historically high times. Additional methods for selling were implemented into each strategy including All Time High sales, sales made when there is a Five Percent Drop from the Ten Day High, and End of the Year Trailing Stop sales. Multi-year sales were also considered separately and included the same strategies and methods for selling. Results showed that all strategies out-performed USDA average farm prices received for the period examined. The results of this research could shape future models and increase economic gains for agricultural producers.

description: Solving instability of Savvidy vacuum in QCD is a longstanding problem. Using light cone quantization we analyze the problem not in the real confining vacuum but in dense quark matter where gluons interact weakly with each other. We find a stable ferromagnetic ground state of gluons which carry a single longitudinal momentum. Their states are composed as if they are confined in a two dimensional quantum well. This supports our previous result that gluons form a quantum Hall state in dense quark matter.

The dependence of the revival time on various parameters of the driven system is shown analytically. As an example of application of our approach, we compare the analytically obtained values of the revival time for various modulation strengths with the numerically computed ones in the case of a driven gravitational cavity. We show that they are in very good agreement.

description: Plastic scintillator detectors are widely used in particle physics thanks to the very good particle identification, tracking capabilities and time resolution. However, new experimental challenges and the need for enhanced performance require the construction of detector geometries that are complicated using the current production techniques. In this article we propose a new production technique based on additive manufacturing that aims to 3D print polystyrene-based scintillator. The production process and the results of the scintillation light output measurement of the 3D-printed scintillator are reported.

description: Although more than twenty years have passed since the discovery of high temperature cuprate superconductivity, the identification of the superconducting order parameter is still under debate. Here, we show that the nodal gap component is the best candidate for the superconducting order parameter. It scales with the critical temperature $T_c$ over a wide doping range and displays a significant temperature dependence below $T_c$ in both the underdoped and the overdoped regimes of the phase diagram. In contrast, the antinodal gap component does not scale with $T_c$ in the underdoped side and appears to be controlled by the pseudogap amplitude. Our experiments establish the existence of two distinct gaps in the underdoped cuprates.

Publisher: name: University of British Columbia
Year: 2009

description: This replication study describes public health nurses, perceptions of their role in health promotion. It is based on Berland and Whyte's study of hospital nurses' role in health promotion. Public health nurses' knowledge, attitudes, and activities in health promotion were examined using a cross-sectional study design. Facilitators of and barriers to health promotion practice were identified . The questionnaire from the original study was revised to reflect the practice of public health nurses and mailed to a random sample of registered nurses practicing in community nursing in British Columbia. Data analysis was based on 211 of the returned questionnaires. The results clearly indicate that public health nurses value health promotion. Public health nurses perceive that they have the experience, knowledge, skills , and abilities and include health promotion activities in their daily practice. They report using a variety of strategies including teaching, promotion of healthy lifestyles, advocacy, and counselling to help clients enhance their coping skills, knowledge, and participation in identifying and addressing their own health issues. Facilitators of health promotion practice include work environments that are characterized by supportive colleagues, teamwork, and administrators that foster risk taking, support creativity, and provide encouragement. The majority of public health nurses report feeling stimulated about their practice, having opportunities to be creative and innovative in their practice, and feeling a sense of accomplishment. Most public health nurses believe they make a difference in the lives of clients. Research based practice is valued but many public health nurses believe that determination and evaluation of health promotion outcomes is required. Barriers to health promotion practice are limited availability of resources and resource coordination, time constraints, and lack of computerized records. The public and others' lack of knowledge and understanding about the role of public health nurses act as barriers. Public health nurses also expressed concern that there is a lack of government commitment to health promotion. Implications for nursing research, education, practice, and administration were identified.

Some effects of forest floor displacement on soil properties and lodgepole pine productivity in the Boundary Forest District
Creators: name: Hickling, James S. B.
Publisher: name: University of British Columbia
Year: 2009

description: Forest floor displacement occurs during ground skidding and other forest harvesting and silvicultural operations. It includes excavation, scalping, mineral soil exposure, and burial of the forest floor. Two aspects of forest floor displacement can result in soil degradation and may impede forest regeneration; the redistribution and loss of nutrients, and the exposure of unfavourable rooting medium. Current soil conservation regulations, introduced by the new British Columbia Forest Practices Code, limit the amount of forest floor displacement that is acceptable during harvesting operations. However, the limits imposed by the Code are contentious, especially in Boundary Forest District, where the prevailing soil conditions are regarded as being particularly sensitive to forest floor displacement by some foresters and particularly tolerant of it by others. Evidence regarding the long-term biological sustainability of forest floor displacement is needed to confirm or amend the current restrictions on forest floor displacement. A retrospective study of the effects of forest floor displacement on lodgepole pine productivity was performed. Soils were surveyed for forest floor displacement atfive sites and samples were analyzed to assess the impact of forest floor displacement on soil nutritional properties. Foliar tissue samples were collected at four sites and analyzed to assess the nutritional impact of forest floor displacement on lodgepole pine trees. Growth of trees ranging in age from three to twenty seven-years-old was assessed at four sites and stem productivity was related to the amount of forest floor displacement present around each stem. Soil organic matter content, total N and total C are reduced by forest floor displacement, while available P increases and the C:N ratio decreases. Soil chemical analysis suggests that although forest floor displacement results in a reduction in total soil nutrient content, the nutrients present on scalped soils may be more available for root uptake. Changes in the above soil properties are shown to be temporary as soils appear to recover from forest floor displacement over time. Statistically significant differences in foliar nutrient concentration are infrequent among seedlings growing on scalped and control soils. The mean foliar concentrations of macronutrients are often slightly higher in scalp trees compared to control trees. Statistically significant differences in seedling productivity are also infrequent, and no permanent, negative impacts on lodgepole pine productivity related to forest floor displacement are indicated. Possible ancillary effects of forest floor displacement on regeneration and stocking density are discussed. Recommendations regarding some aspects of the forest floor displacement regulations and future study are given.

description: We study a relation between nuclear forces based on phenomenological approach (V_ph) and nuclear effective field theory (V_EFT) from a viewpoint of renormalization group. We find the relation between these two types of nuclear force using Wilsonian renormalization group equation. Considering the fact that V_EFT is defined in a certain small model space, we show that a simple contact interaction accurately simulates short-distance physics, and that V_EFT is free from dependence on modelling the details of the short-distance physics. Based on our result, we discuss some features of nuclear effective field theory.

description: In this work, we examine the impact of Treadmill Assisted Gait Spoofing (TAGS) on Wearable Sensor-based Gait Authentication (WSGait). We consider more realistic implementation and deployment scenarios than the previous study, which focused only on the accelerometer sensor and a fixed set of features. Specifically, we consider the situations in which the implementation of WSGait could be using one or more sensors embedded into modern smartphones. Besides, it could be using different sets of features or different classification algorithms, or both. Despite the use of a variety of sensors, feature sets (ranked by mutual information), and six different classification algorithms, TAGS was able to increase the average False Accept Rate (FAR) from 4% to 26%. Such a considerable increase in the average FAR, especially under the stringent implementation and deployment scenarios considered in this study, calls for a further investigation into the design of evaluations of WSGait before its deployment for public use.

description: We report first-principles GW-Bethe Salpeter Equation and Quantum Monte Carlo calculations of the optical and electronic properties of molecular and crystalline rubrene (C$_{42}$H$_{28}$). Many-body effects dominate the optical spectrum and quasi-particle gap of molecular crystals. We interpret the observed yellow-green photoluminescence in rubrene microcrystals as a result of the formation of intermolecular, charge-transfer spin-singlet excitons. In contrast, spin-triplet excitons are localized and intramolecular with a predicted phosphorescence at the red end of the optical spectrum. We find that the exchange energy plays a fundamental role in raising the energy of intramolecular spin-singlet excitons above the intermolecular ones. Exciton binding energies are predicted to be around 0.5 eV (spin singlet) to 1 eV (spin triplet). The calculated electronic gap is 2.8 eV. The theoretical absorption spectrum agrees very well with recent ellipsometry data.

description: In January 2019, a government shutdown prevented the U.S. Department of Agriculture from publishing information about the situation and outlook for major U.S. agricultural commodities. We show that, as a result, Chicago Mercantile Exchange Board of Trade markets for corn and soybeans experienced heightened market uncertainty, elevating the cost of hedging. We use historical options data to estimate that the shutdown and publication delay increased the price of hedging, according to two different approaches. If the January 2019 report had been released on time and it had the impact of a normal report at that time of year, ATM corn options would have been 7% ( 6.1% - 8.2%) cheaper, while the price of soybean options would have fallen by 31% (24% - 35%). If the report had instead generated the same IV reduction as the makeup February 2019 publication did, it would have reduced ATM corn and soybean hedging costs by about 22% and 43%, respectively.
The human quest for discovering mathematical beauty in the arts

description: In the words of the twentieth-century British mathematician G. H. Hardy, "the human function is to 'discover or observe' mathematics" (1). For centuries, starting from the ancient Greeks, mankind has hunted for beauty and order in arts and in nature. This quest for mathematical beauty has led to the discovery of recurrent mathematical structures, such as the golden ratio, Fibonacci, and Lucas numbers, whose ubiquitous presences have been tantalizing the minds of artists and scientists alike. The captivation for this quest comes with high stakes. In fact, art is the definitive expression of human creativity, and its mathematical understanding would deliver us the keys for decoding human culture and its evolution (2). However, it was not until fairly recently that the scope and the scale of the human quest for mathematical beauty was radically expanded by the simultaneous confluence of three separate innovations. The mass digitization of large art archives, the surge in computational power, and the development of robust statistical methods to capture hidden patterns in vast amounts of data have made it possible to reveal the---otherwise unnoticeable to the human eye---mathematics concealed in large artistic corpora. Starting from its inception, marked by the foundational work by Birkhoff (3), progress in the broad field of computational aesthetics has reached a scale that would have been unimaginable just a decade ago. The recent expansion is not limited to the visual arts (2) but includes music (4), stories (5), language phonology (6), humor in jokes (7), and even equations (8); for a comprehensive review, see ref. 9.

The versatility of the method is illustrated by constructing matrices whose characteristic polynomials provide the invariants of the kinematical algebras in (3+1)-dimensions. Moreover it is shown, also for kinematical algebras, how some reductions on these matrices are useful for determining the missing operators in the missing label problem (MLP).

description: Minimum variance hedging is probably one of the most popular concepts in the literature on agricultural futures markets. It has been applied many times in the literature, and all studies confirmed that minimum variance hedging has the potential to improve the effectiveness of hedging. However, despite this advantage, no grain merchant has ever used minimum variance hedging in daily business. In this paper we show that grain merchants have a good reason for this. Minimum variance hedging prevents them from trading the basis. If grain merchants do not trade the basis, they will not generate the profits that are necessary to cover the costs of grain storage and will go bankrupt sooner or later. In theory, risk avoidance may be a desirable goal, but in reality, it is not affordable. In fact, the only longterm sustainable strategy is basis trading.

description: After October 1987, financial crisis, market regulators created dispositive called circuit breaks to contain high levels of volatility. As a type of circuit break, price limits were adopted not only on stock markets but in commodity futures contracts as well, however, its effects are not clear. The present study aimed to evaluate price limit ex-ante effects on the four major wheat futures markets by adopting Brogaard and Roshak (2015) methodology by estimating the probability of extreme movements and limit moves conditional to extreme movements and its expost effects on trading activity by contrasting the volume curve on limit days with a counterfactual volume curve that simulates a scenario where price limits were not hit. The results show that tighter limit levels decrease the probability of extreme movements by approximately 0.008% having an overall (four markets included) baseline probability of extreme moves equals 1.11% which agrees with the Holding Back hypothesis assuming extreme movements as a proxy for volatility. On the other hand, the probability of limit moves conditional to extreme movements increases when limit levels are tighter by approximately 0.066% with an overall baseline of 0.05% which supports the “Magnet” hypothesis. Regarding the ex-post effects, longer periods where prices stay at the limit level result in trading activity lost, however, if prices return to limit range but bounce back to a limit lock, the longer the gap between limit locks trading session experience an increase in trading activity. Moreoever, the ex-post effects on trading activity are more intense in Chicago relative to Kansas City because Chicago present a higher trading volume on average.
Factorization method with one plane wave: from model-driven and data-driven perspectives

description: The factorization method by Kirsch (1998) provides a necessary and sufficient condition for characterizing the shape and position of an unknown scatterer by using far-field patterns of infinitely many time-harmonic plane waves at a fixed frequency. This paper is concerned with the factorization method with a single far-field pattern to recover a convex polygonal scatterer/source. Its one-wave version relies on the absence of analytical continuation of the scattered/radiated wave-fields in corner domains. It can be regarded as a domain-defined sampling method and does not require forward solvers. In this paper we provide a rigorous mathematical justification of the one-wave factorization method and present some preliminary numerical examples. In particular, the proposed scheme can be interpreted as a model-driven and data-driven method, because it essentially depends on the scattering model and a priori given \emph{sample data}.

description: We have observed depolarization effects when high intensity cold neutron beams are incident on alkali-metal-spin-exchange polarized He-3 cells used as neutron spin filters. This was first observed as a reduction of the maximum attainable He-3 polarization and was attributed to a decrease of alkali-metal polarization, which led us to directly measure alkali-metal polarization and spin relaxation over a range of neutron fluxes at LANSCE and ILL. The data reveal a new alkali-metal spin-relaxation mechanism that approximately scales as the square root of the neutron capture-flux density incident on the cell. This is consistent with an effect proportional to the recombination-limited ion concentration, but is much larger than expected from earlier work.

description: This paper considers the secrecy performance of several schemes for multi-antenna transmission to single-antenna users with full-duplex (FD) capability against randomly distributed single-antenna eavesdroppers (EDs). These schemes and related scenarios include transmit antenna selection (TAS), transmit antenna beamforming (TAB), artificial noise (AN) from the transmitter, user selection based their distances to the transmitter, and colluding and non-colluding EDs. The locations of randomly distributed EDs and users are assumed to be distributed as Poisson Point Process (PPP). We derive closed form expressions for the secrecy outage probabilities (SOP) of all these schemes and scenarios. The derived expressions are useful to reveal the impacts of various environmental parameters and user's choices on the SOP, and hence useful for network design purposes. Examples of such numerical results are discussed.

Sequencing adjacent to BssHII sites on human chromosome 8 : a method of gene identification
Creators: name: Debella, Leah Rae
Publisher: name: University of British Columbia
Year: 2009

description: Considerable research is focused on the identification of genes in the human genome. Recently, the Human Genome project has named gene identification as one of its goals to be accomplished in tandem with mapping and sequencing of the entire genome. As a result,a large program centered on the creation of expressed sequence tags (ESTs) is currently underway. Although this method of gene identification has vastly increased the number of expressed sequences in the database, it is unlikely that all genes encoded in the genome with be detected though the sequencing of cDNAs. An alternative method of gene identification, using genomic DNA, is the sequencing of regions adjacent to rare cutting enzyme sites. Recognition sites of rare cutting enzymes are found infrequently in genomic DNA but cluster in regions known as CpG islands. CpG islands are associated with most ubiquitously expressed genes and 40% of tissue specific genes. Therefore, sequencing of these regions offers a complementary method to be used in the recognition of novel genes. The objective of this project was to identify novel genes present in cloned DNA from human chromosome 8 using BssHII, a rare cutting enzyme.BssHII, is an excellent choice to be used in this manner, as 80% of its sites are located in CpG islands. DNA adjacent to fourteen Bssrlll sites, originating from eleven cosmids, was sequenced. From this set two human ESTs were identified; two open reading frames with no apparent homologues; two CpG islands, one of which contains a translation initiation signal and is 5' of the EST H88121; and two novel human genes. These results validate the hypothesis that the use of this method can complement other techniques in the identification of novel genes in the human genome.

Religious coexistence

description: Dissemination of the results of the workshop The workshop is a part of Work Package 7 “History of Religious Studies in the Age of Big-Data: Developing New Methodologies” and a central output of the Task 7.2 “Religious conflicts, peacemaking, and the shaping of reflective European societies”. “The task examines how the creation of an academic community on religious studies in a pan-European historical perspective can interact with processes of religious (and secular) community and identity building on a regional and local level. It aims to show to what extent and in which ways a transnational academic approach to historical religious issues can interact with the internal dynamics of religious and non-religious groups, and how a historical analysis of European religious diversity and conflict in a global context can foster the implementation of interreligious and religious-secular dialogue in European societies.”1 To reach the stated aims a workshop on religious peace-making and coexistence was organized by the IEG on 19/20.09.2019 with a title "The practice of religious toleration in past and contemporary Europe".
On radiative corrections for unpolarized electron proton elastic scattering
Creators: name: Tomasi-Gustafsson, Egle
Publisher: name: arXiv
Year: 2006
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: A statistical analysis of the elastic unpolarized electron proton scattering data shows that, at large momentum transfer, the size and the $ε$ dependence of the radiative corrections, as traditionally calculated and applied, may induce large correlations of the parameters of the Rosenbluth fit, which prevent a correct extraction of the electric proton form factor. Using the electron QED structure (radiation) function approach the cross section of elastic electron-proton scattering in leading and next-to leading approximations is calculated and expressed as a correction to the Born cross section, which is different for the electric and the magnetic contribution. When properly applied to the data, it may give the solution to the problem of the discrepancy of the polarized and unpolarized results on electron proton scattering.

Fluctuation theorems for quantum master equations

description: A quantum fluctuation theorem for a driven quantum subsystem interacting with its environment is derived based solely on the assumption that its reduced density matrix obeys a closed evolution equation i.e. a quantum master equation (QME). Quantum trajectories and their associated entropy, heat and work appear naturally by transforming the QME to a time dependent Liouville space basis that diagonalizes the instantaneous reduced density matrix of the subsystem. A quantum integral fluctuation theorem, a steady state fluctuation theorem and the Jarzynski relation are derived in a similar way as for classical stochastic dynamics.

description: Ontology-mediated query answering (OMQA) is a promising approach to data access and integration that has been actively studied in the knowledge representation and database communities for more than a decade. The vast majority of work on OMQA focuses on conjunctive queries, whereas more expressive queries that feature counting or other forms of aggregation remain largely unex-plored. In this paper, we introduce a general form of counting query, relate it to previous proposals, and study the complexity of answering such queries in the presence of DL-Lite ontologies. As it follows from existing work that query answering is intractable and often of high complexity, we consider some practically relevant restrictions, for which we establish improved complexity bounds.

description: We study some spectral sequences associated with a locally free $\mathcal O_X$-module $\mathcal A$ which has a Lie algebroid structure. Here $X$ is either a complex manifold or a regular scheme over an algebraically closed field $k$. One spectral sequence can be associated with $\mathcal A$ by choosing a global section $V$ of $\mathcal A$, and considering a Koszul complex with a differential given by inner product by $V$. This spectral sequence is shown to degenerate at the second page by using Deligne's degeneracy criterion. Another spectral sequence we study arises when considering the Atiyah algebroid $\mathcal D_E$ of a holomolorphic vector bundle $E$ on a complex manifold. If $V$ is a differential operator on $E$ with scalar symbol, i.e, a global section of $\mathcal D_E$, we associate with the pair $(E,V)$ a twisted Koszul complex. The first spectral sequence associated with this complex is known to degenerate at the first page in the untwisted ($E=0$) case

description: A generalized mass formula is used to calculate the neutron and proton drip lines of normal and lambda hypernuclei treating non-strange and strange nuclei on the same footing. Calculations suggest existence of several bound hypernuclei whose normal cores are unbound. Addition of Lambda or, Lambda-Lambda hyperon(s) to a normal nucleus is found to cause shifts of the neutron and proton driplines from their conventional limits.

description: RELIANCE, short for Research Lifecycle Management for Earth Science Communities and Copernicus users in EOSC, aims to realize the vision of FAIR research in EOSC by adopting a holistic research management approach based on three key and complementary technologies: i) Research objects (RO) as the overarching mechanism to manage scientific research activities; ii) data cubes as the mechanisms enabling an efficient and scalable Earth Observation data discovery and access; iii) text mining and semantic enrichment services allowing to extract machine-readable metadata from RO resources, enabling researchers to discover scientific information at scale and to structure their own research. This document is the second release of the Data Cube API which describes how to exploit the FAIR Data Cubes made available within the RELIANCE project. The Data Cube Metadata Model adopted for describing FAIR Data Cubes and the list of Data Cube resources are detailed in the D4.1 and D4.3, respectively.
Particlization of an interacting hadron resonance gas with global conservation laws for event-by-event fluctuations in heavy-ion collisions

description: We revisit the problem of particlization of a QCD fluid into hadrons and resonances at the end of the fluid dynamical stage in relativistic heavy-ion collisions in a context of fluctuation measurements. The existing methods sample an ideal hadron resonance gas, therefore, they do not capture the non-Poissonian nature of the grand-canonical fluctuations, expected due to QCD dynamics such as the chiral transition or QCD critical point. We address the issue by partitioning the particlization hypersurface into locally grand-canonical fireballs populating the space-time rapidity axis that are constrained by global conservation laws. The procedure allows to quantify the effect of global conservation laws, volume fluctuations, thermal smearing and resonance decays on fluctuation measurements in various rapidity acceptances, and can be used in fluid dynamical simulations of heavy-ion collisions. As a first application, we study event-by-event fluctuations in heavy-ion collisions at the LHC using an excluded volume hadron resonance gas model matched to lattice QCD susceptibilities, with a focus on (pseudo)rapidity acceptance dependence of net baryon, net proton, and net charge cumulants. We point out large differences between net proton and net baryon cumulant ratios that make direct comparisons between the two unjustified. We observe that the existing experimental data on net-charge fluctuations at the LHC shows a strong suppression relative to a hadronic description.
