description: The project is to investigate the best plant as fuelstock that can be grown in UBC farm, which is a 24 hectre farm on the southern end of the University of British Columbia (UBC). The Triple Bottom Line method is implemented during the entire investigation. Since several fuelstock options can be grown in UBC farm, the best candidate should chosen based on economical, ecological and social indicators. The result is derived by estimation since all data are collected from other papers and online resources. The economic indicators include input costs and profit generated by trading Miscanthus with the Bioenergy Research Demonstration Facility (BRDF). The ecological indicators applied are reusability of existing space and materials, improvement in environmental condition, protection from environmental degradation and increase in sustainable practice. Also, the social indicators consist of potential job increases, improvement of relations across sectors and providing educational opportunities. The result shows that Miscanthus is the best option and is highly recommended. Although the UBC farm may not provide the enough land to grow Miscanthus and supply the entire operation of BRDF, the pattem and model can be transfered to other parts of British Columbia (BC) and be implemented. In short terms, there is money input to the project, however, from long run perspectives, society and ecology environment will benefit of low greenhouse gas(GHG) emissions.

description: Membrane receptors for neuromodulators (NM) are highly regulated in their distribution and efficacy - a phenomenon which influences the individual cell's response to central signals of NM release. Even though NM receptor regulation is implicated in the pharmacological action of many drugs, and is also known to be influenced by various environmental factors, its functional consequences and modes of action are not well understood. In this paper we summarize relevant experimental evidence on NM receptor regulation (specifically dopamine D1 and D2 receptors) in order to explore its significance for neural and synaptic plasticity. We identify the relevant components of NM receptor regulation (receptor phosphorylation, receptor trafficking and sensitization of second-messenger pathways) gained from studies on cultured cells. Key principles in the regulation and control of short-term plasticity (sensitization) are identified, and a model is presented which employs direct and indirect feedback regulation of receptor efficacy. We also discuss long-term plasticity which involves shifts in receptor sensitivity and loss of responsivity to NM signals. Finally, we discuss the implications of NM receptor regulation for models of brain plasticity and memorization. We emphasize that a realistic model of brain plasticity will have to go beyond Hebbian models of long-term potentiation and depression. Plasticity in the distribution and efficacy of NM receptors may provide another important source of functional plasticity with implications for learning and memory.

description: This study uses firm level data on 19 Sub-Saharan Africa countries between 2004 and 2016 to provide a rigorous analysis on the impact of Chinese import competition on productivity, skills, and performance of firms., We measure import competition and ports accessibility at the city-industry level to identify the relevance of firms’ location in determining the impact of Chinese imports competition. To address endogeneity concerns, a time-varying instrument for Chinese imports based on the interaction between an exogenous geographic characteristic and a shock in transportation technology is developed. The results show that imports competition has a positive impact on firm performance, mainly in terms of productivity catch-up and skills upgrading. Of particular interest is the finding that the effects of import competition from China are stronger for more remote firms that have lower port accessibility, an indication that Chinese imports in remote areas improves productivity of laggard firms, employment, and intensity of skilled workers. Our findings indicate that African firms are improving their performance as a consequence of the higher Chinese import intensity, mainly through direct competition and the use of higher quality inputs of production sourced from China.

description: A society that believes wealth to be determined by random “luck” rather than by merit, demands more redistribution. The theoretical literature shows that any increase in the volatility of income caused by unpredictable adverse shocks implies a higher support for redistribution. We present evidence of this behavior by exploiting a natural experiment provided by the L’Aquila earthquake in 2009, which hit a large area of Central Italy through a series of destructive shakes over eight days. Matching detailed information on the ground acceleration registered during each shock with survey data about individual opinions on redistribution we show that the average intensity of the shakes is associated with subsequent stronger beliefs that, for a society to be fair, income inequalities should be levelled by redistribution. The shocks, however, are not all alike. We find that only the last three shakes - occurred on the fourth and the eighth day of the earthquake - have a statistically significant impact. Overall, we find that the timing and repetition of the shock play a role in shaping redistributive preferences.

description: Lymphatic filariasis (LF) is endemic in 72 countries; 15 million persons live with chronic filarial lymphedema. It can be a disabling condition, frequently painful, leading to reduced mobility, social exclusion, and depression. The Global Program to Eliminate Lymphatic Filariasis aims to stop new infections and care for affected persons, but morbidity management has been initiated in only 38 countries. We examine economic costs and benefits of alleviating chronic lymphedema and its effects through simple limb care. We use economic and epidemiological data from 12 Indian states in which 99% of Indians with filariasis reside. Using census data, we calculate the age distribution of filarial lymphedema and predict the burden of morbidity of infected persons. We estimate lifetime medical costs and lost earnings due to lymphedema and acute dermatolymphangioadenitis (ADLA) with and without community-based limb-care programs. Programs of community-based limb care in all Indian endemic areas would reduce costs of disability by 52%, saving a per person average of US$2,721, equivalent to 703 workdays. Per-person savings are 185 times the program’s per-person cost. Chronic lymphedema and ADLA impose a substantial physical and economic burden in filariasis-endemic areas. Low-cost programs for lymphedema management based on limb washing and topical medication are effective in reducing the number of ADLA episodes and stopping progression of disabling lymphedema. With reduced disability, people can work longer hours per day, more days per year, and in more strenuous, higher paying jobs, resulting in important economic benefits to themselves, their families, and their communities.

description: We derive the quantum Einstein equations (which are the quantum generalisation of the Einstein equations of classical gravity) from Bohmian quantum gravity. Bohmian quantum gravity is a non-classical geometrodynamics (in the ADM formalism) which describes the time evolution of a 3-geometry and of a matter field (or other matter degrees of freedom) on a three manifold. The evolution is determined by a velocity law which is defined by the wave function. The wave function itself satisfies the Wheeler-DeWitt equation. We cast the Bohmian dynamics into the form of the Einstein field equations, where the interesting novelty is a contribution to the energy-momentum tensor that depends on the quantum potential.

description: We perform a study of the non-perturbative dynamics of the light-quark sector of QCD, based on some recent results of lattice simulations with chiral fermions. We analyze some correlators that are designed to probe the Dirac structure of the quark-quark interaction at different scales. We show that, in the non-perturbative regime, such an interaction contains very large scalar and pseudo-scalar components. We observe quantitative agreement between lattice QCD results and the predictions of the Instanton Liquid Model (ILM). Moreover, we study how the the quark-quark interaction is modified, when quark loops are suppressed. We observe a dramatic effect related to the loss of unitarity, which is naturally explained in the instanton picture. Such an effect cannot be explained in a Dyson-Schwinger Equations (DSE) approach, if one assumes a simple vector quark-gluon coupling. Therefore, from the present study it emerges that DSE models with such an ansatz for the vertex function are not consistent with QCD.

description: High levels of heterozygosity present a unique genome assembly challenge and can adversely impact downstream analyses, yet is common in sequencing datasets obtained from non-model organisms. Here we show that by re-assembling a heterozygous dataset with variant parameters and different assembly algorithms, we are able to generate assemblies whose protein annotations are statistically enriched for specific gene ontology categories. While total assembly length was not significantly affected by assembly methodologies tested, the assemblies generated varied widely in fragmentation level and we show local assembly collapse or expansion underlying the enrichment or depletion of specific protein functional groups. We show that these statistically significant deviations in gene ontology groups can occur in seemingly high-quality assemblies, and result from difficult-to-detect local sequence expansion or contractions. Given the unpredictable interplay between assembly algorithm, parameter, and biological sequence data heterozygosity, we highlight the need for better measures of assembly quality than N50 value, including methods for assessing local expansion and collapse.

description: The French young beef bull sector presents a complex organisation. The more animals are mixed and subjected to long transports, the more likely they will be to develop bovine respiratory disease (BRD). We aimed to understand the vertical integration patterns in the young beef bull sector and how they influence public health issues (BRD and antibiotic use). Transaction costs analyses revealed a diversity of vertical integration patterns, from spot market to vertical integration. The “health issues” parameter is involved in different categories of transaction costs (risk, uncertainty, quality). When vertical integration is strong (weak), the risk of BRD is low (high), which thus have an indirect effect on antibiotic use.

description: Based on the CCD observations of remote young open clusters NGC 2383, NGC 2384, NGC 4103, NGC 4755, NGC 7510 and Hogg 15, we constructed their observed luminosity functions (LFs). The observed LFs are corrected for field star contamination determined with the help of galactic star count model. In the case of Hogg 15 and NGC 2383 we also considered the additional contamination from neighbouring clusters NGC 4609 and NGC 2384 respectively. These corrections provided the realistic pattern of cluster LF in the vicinity of the MS turn on point and at fainter magnitudes, revealed the so called H-feature arising due to transition of the Pre-MS phase to MS, which is dependent on the cluster age. The theoretical LFs were constructed representing a cluster population model with continuous star formation for a short time scale and a power law Initial Mass Function (IMF) and these were fitted to the observed LF. As a result we are able to determine for each cluster a set of parameters, describing cluster population (the age, duration of star formation, IMF slope and percentage of field star contamination). It was found that in spite of the non-monotonic behaviour of observed LFs, cluster IMFs can be described as the power law functions with slopes similar to Salpeter's value. The present MS turn on cluster ages are several times lower than those derived from the fitting of theoretical isochrones to the turn off region of the upper Main Sequences.

Holomorphic almost modular forms

Publisher: name: arXiv

Subjects: subject: Number Theory (math.NT)
subject: FOS: Mathematics

description: Holomorphic almost modular forms are holomorphic functions of the complex upper half plane which can be approximated arbitrarily well (in a suitable sense) by modular forms of congruence subgroups of large index in $\SL(2,\ZZ)$. It is proved that such functions have a rotation-invariant limit distribution when the argument approaches the real axis. An example for a holomorphic almost modular form is the logarithm of $\prod_{n=1}^\infty (1-\exp(2\piın^2 z))$. The paper is motivated by the author's studies [J. Marklof, Int. Math. Res. Not. {\bf 39} (2003) 2131-2151] on the connection between almost modular functions and the distribution of the sequence $n^2x$ modulo one.

description: We study the relative risk aversion of an individual with particular social preferences: his wellbeing is influenced by his relative wealth, and by how concerned he is about having low relative wealth. Holding constant the individual’s absolute wealth, we obtain two results. First, if the individual’s level of concern about low relative wealth does not change, the individual becomes more risk averse when he rises in the wealth hierarchy. Second, if the individual’s level of concern about low relative wealth intensifies when he rises in the wealth hierarchy and if, in precise sense, this intensification is strong enough, then the individual becomes less risk averse: the individual’s desire to advance further in the wealth hierarchy is more important to him than possibly missing out on a better rank.
A theoretical analysis of the systematic errors in the Red Clump distance to the LMC

description: We present a detailed analysis of the uncertainty on the theoretical population corrections to the LMC Red Clump (RC) absolute magnitude, by employing a population synthesis algorithm to simulate theoretically the photometric and spectroscopic properties of RC stars, under various assumptions about the LMC Star Formation Rate (SFR) and Age Metallicity Relationship (AMR). A comparison of the outcome of our simulations with observations of evolved low-intermediate mass stars in the LMC allows one to select the combinations of SFR and AMR that bracket the real LMC star formation history, and to estimate the systematic error on the associated RC population corrections. The most accurate estimate of the LMC distance modulus from the RC method (adopting the OGLE-II reddening maps for the LMC) is obtained from the K-band magnitude, and provides (m-M)_{0, LMC}=18.47 +/-0.01(random) +0.05/-0.06(systematic). Distances obtained from the I-band, or from the multicolour RC technique which determines at the same time reddening and distance, both agree (albeit with a slightly larger error bar) with this value.

description: By band engineering the iron chalcogenide Fe(Se,Te) via ab-initio calculations, we search for topological surface states and realizations of Majorana bound states. Proposed topological states are expected to occur for non-stoichiometric compositions on a surface Dirac cone where issues like disorder scattering and charge transfer between relevant electronic states have to be addressed. However, this surface Dirac cone is well above the Fermi-level. Our goal is to theoretically design a substituted crystal in which the surface Dirac cone is shifted towards the Fermi-level by modifying the bulk material without disturbing the surface. Going beyond conventional density functional theory (DFT), we apply the coherent potential approximation (BEB-CPA) in a mixed basis pseudo-potential framework to scan the substitutional phase-space of co-substitutions on the Se-sites. We have identified iodine as a promising candidate for intrinsic doping. Our specific proposal is that FeSe$_{0.325}$I$_{0.175}$Te$_{0.5}$ is a very likely candidate to exhibit a Dirac cone right at the Fermi energy without inducing strong disorder scattering.

description: Acknowledging individuals’ distaste for low relative income renders trade less appealing when trade is viewed as a technology that integrates economies by merging separate social spheres into one. We define a “trembling trade” as a situation in which gains from trade are overtaken by losses of relative income, with the result that global social welfare is reduced. A constructive example reveals that a “trembling trade” can arise even when trade is doubly gainful in that it increases the income of every individual and narrows the income gap between the trading populations.

description: A rationale for providing support to the farm sector in the course of economic development and structural change is a growing gap between the incomes of non-agricultural workers and the incomes of farmers. Drawing on a model that enables us to analyze the level of social stress experienced by farmers as employment shifts from the farm sector to other sectors, we find that even without an increasing gap between the incomes of non-agricultural workers and the incomes of farmers, support to farmers might be needed/can be justified. This result arises because under well specified conditions, when the size of the farm population decreases, those who remain in farming experience increasing aggregate social stress. The increase is nonlinear: it is modest when the outflow from the farm sector is relatively small or when it is large, and it becomes more significant when the outflow is moderate. This finding can inform policy makers who seek to alleviate the social stress of the farming population as to the timing and intensity of that intervention.
Modeling the accretion history of supermassive black holes

Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)

description: There is overwhelming evidence for the presence of supermassive black holes (SMBHs) in the centers of most nearby galaxies. The mass estimates for these remnant black holes from the stellar kinematics of local galaxies and the quasar phenomenon at high redshifts point to the presence of assembled SMBHs. The accretion history of SMBHs can be reconstructed using observations at high and low redshifts as model constraints. Observations of galaxies and quasars in the submillimeter, infrared, optical, and X-ray wavebands are used as constraints, along with data from the demography of local black holes. Theoretical modeling of the growth of black hole mass with cosmic time has been pursued thus far in two distinct directions: a phenomenological approach that utilizes observations in various wavebands, and a semi-analytic approach that starts with a theoretical framework and a set of assumptions with a view to matching observations. Both techniques have been pursued in the context of the standard paradigm for structure formation in a Cold Dark Matter dominated universe. Here, we examine the key issues and uncertainties in the theoretical understanding of the growth of SMBHs.

description: We study higher-dimensional non-supersymmetric orbifold models where the Higgs field is identified with some internal component of a gauge field. We address two important and related issues that constitute severe obstacles towards model building within this type of constructions: the possibilities of achieving satisfactory Yukawa couplings and Higgs potentials. We consider models where matter fermions are localized at the orbifold fixed-points and couple to additional heavy fermions in the bulk. When integrated out, the latter induce tree-level non-local Yukawa interactions and a quantum contribution to the Higgs potential that we explicitly evaluate and analyse. The general features of these highly constrained models are illustrated through a minimal but potentially realistic five-dimensional example. Finally, we discuss possible cures for the persisting difficulties in achieving acceptable top and Higgs masses. In particular, we consider in some detail the effects induced in these models by adding localized kinetic terms for gauge fields.

Weight approximation for spatial outcomes
Creators: name: Simon, Jay
Publisher: name: American University
Year: 2023

description: When preferences explicitly include a spatial component, it can be challenging to assign weights to geographic regions in a way that is both pragmatic and accurate. In multi-attribute decision making, weights reflect cardinal information about preferences that can be difficult to assess thoroughly in practice. Recognizing this challenge, researchers have developed several methods for using ordinal rankings to approximate sets of cardinal weights. However, when the set of weights reflects a set of geographic regions, the number of weights can be enormous, and it may be cognitively challenging for decision makers to provide even a coherent ordinal ranking. This is often the case in policy decisions with widespread impacts. This paper uses a simulation study for spatial preferences to evaluate the performance of several rank-based weight approximation methods, as well as several new methods based on assigning each region to a tier expressing the extent to which it should influence the evaluation of policy alternatives. The tier-based methods do not become more cognitively complex as the number of regions increases, they allow decision makers to express a wider range of preferences, and they are similar in accuracy to rank-based methods when the number of regions is large. The paper then demonstrates all of these approximation methods with preferences for water usage by census block in a United States county.

description: We have performed a systematic analysis of the dynamics of different galaxy populations in galaxy groups from the 2dFGRS. For this purpose we have combined all the groups into a single system, where velocities v and radius r are expressed adimensionally. We have used several methods to compare the distributions of relative velocities of galaxies with respect to the group centre for samples selected according to their spectral type (as defined by Madgwick et al., 2002), bj band luminosity and B-R colour index. We have found strong segregation effects: spectral type I objects show a statistically narrower velocity distribution than that of galaxies with a substantial star formation activity (type II-IV). Similarly, the same behavior is observed for galaxies with colour index B-R>1 compared to galaxies with B-R<1. Bright (Mb-19) galaxies show the same segregation. It is not important once the sample is restricted to a given spectral type. These effects are particularly important in the central region (Rp

description: A test for the presence of serial correlation is routinely carried out as a test for efficiency in fmancial markets. The problems inherent in such testing in the presence of dynamic heteroscedasticity are addressed in this paper. The accuracy of using standard critical values of serial correlation tests in the presence of autoregressive conditional heteroscedasticity (ARCH), generalized ARCH (GARCH), normal and non-normal disturbances is investigated. Tests examined include the conventional Durbin-Watson, Box-Pierce, Ljung-Box, Lagrange multiplier tests, proposed ARCH-corrected versions of these tests, and the robust tests of Diebold (1986) and Wooldridge (1992). Standard serial correlation tests are derived assuming that the disturbances are homoscedastic, but this study shows that asymptotic critical values are not accurate when this assumption is violated. Asymptotic critical values for the ARCH(2)-corrected LM, BP and BL tests are valid only when the underlying ARCH process is strictly stationary, whereas Wooldridge's robust LM test has good size and power properties overall. These tests exhibit similar behaviour even when the underlying process is GARCH (1, 1). When the regressors include lagged dependent variables, the sizes and powers of the corrected tests depend on the coefficient of the lagged dependent variables, and the ratio of signal to noise. They appear to be robust across various disturbance distributions.
Symmetry resolved entanglement in two-dimensional systems via dimensional reduction

description: We report on the calculation of the symmetry resolved entanglement entropies in two-dimensional many-body systems of free bosons and fermions by \emph{dimensional reduction}. When the subsystem is translational invariant in a transverse direction, this strategy allows us to reduce the initial two-dimensional problem into decoupled one-dimensional ones in a mixed space-momentum representation. While the idea straightforwardly applies to any dimension $d$, here we focus on the case $d=2$ and derive explicit expressions for two lattice models possessing a $U(1)$ symmetry, i.e., free non-relativistic massless fermions and free complex (massive and massless) bosons. Although our focus is on symmetry resolved entropies, some results for the total entanglement are also new. Our derivation gives a transparent understanding of the well known different behaviours between massless bosons and fermions in $d\geq2$: massless fermions presents logarithmic violation of the area which instead strictly hold for bosons, even massless. This is true both for the total and the symmetry resolved entropies. Interestingly, we find that the equipartition of entanglement into different symmetry sectors holds also in two dimensions at leading order in subsystem size; we identify for both systems the first term breaking it. All our findings are quantitatively tested against exact numerical calculations in lattice models for both bosons and fermions.

description: : Scene classification relying on images is essential in many systems and applications related to remote sensing. The scientific interest in scene classification from remotely collected images is increasing, and many datasets and algorithms are being developed. The introduction of convolutional neural networks (CNN) and other deep learning techniques contributed to vast improvements in the accuracy of image scene classification in such systems. To classify the scene from areal images, we used a two-stream deep architecture. We performed the first part of the classification, the feature extraction, using pre-trained CNN that extracts deep features of aerial images from different network layers: the average pooling layer or some of the previous convolutional layers. Next, we applied feature concatenation on extracted features from various neural networks, after dimensionality reduction was performed on enormous feature vectors. We experimented extensively with different CNN architectures, to get optimal results. Finally, we used the Support Vector Machine (SVM) for the classification of the concatenated features. The competitiveness of the examined technique was evaluated on two real-world datasets: UC Merced and WHU-RS. The obtained classification accuracies demonstrate that the considered method has competitive results compared to other cutting-edge techniques.
