description: We present the results of two investigations into the nature of strong (rest equivalent width > 1.0 Ang) Mg II absorption systems at high redshift. The first line of questioning examines the complete SDSS- DR3 set of quasar spectra to determine the evolution of the incidence of strong Mg II absorption. The redshift evolution of the comoving line-of-sight number density, l(x), is characterized by a roughly constant value at z > 0.8, indicating that the product of the number density and gas cross-section of halos hosting strong Mg II is unevolving at these redshifts. At z < 0.8 there is a decline in l(x), which we interpret as a decrease in the gas cross-section to strong Mg II absorption and therefore a decline in the physical processes relevant to such absorption. This evolution roughly tracks the global evolution of the SFR density. The decrease of l(x) is more pronounced for larger equivalent width systems. We also present the results of a search for strong Mg II absorption in 91 high resolution quasar spectra, which allow us to investigate the kinematics of such systems. These systems are characterized by the presence of numerous components spread over a ~200 km/s velocity width and the presence of more highly ionized species, which display kinematic profiles similar to the corresponding Mg II absorption. We consider these results in light of two competing theories to explain strong Mg II absorption: post-starburst, SN-driven galactic winds and accreting gas in the halos of massive galaxies. The later model is disfavored by the absence of evolution in l(x) at z > 1. We argue that the strong Mg II phenomenon primarily arises from feedback processes in relatively low mass galactic halos related to star formation.

description: Quantitative policy analysts are usually confronted with the problem to derive a base-line scenario that reflects the most likely state of an economy in a future year. The methods used in practice to derive such a base-line scenarios are heterogeneous and range from the usage of the last observable year to complete and consistent estimation procedures. In the case of general equilibrium (CGE) analyses, the Scenar2020 project (European Commission 2006a) is one example how projections of macro-economic indicators (exogenous drivers) are used to construct the base-line as a model scenario: Starting from a calibrated version, exogenous variables are modified until macro-economic projections are met. However, numerous projections refer to economic indicators which are endogenous variables within the CGE framework, such as gross domestic product (GDP), market prices, or produced quantities. To investigate methods that allow integrating projections for endogenous CGE variables is the main topic of this study. Our starting point is the work by Arndt et al (2002), where entropy-based (Golan et al 1996) techniques are employed for the estimation of behavioural parameters by fitting a CGE model to time series on endogenous variables. Following this concept, we investigate a method to fit a CGE´s parameters and endogenous variables to market- and macro-economic projections from major research institutes.
Multireference configuration interaction treatment of excited-state electron correlation in periodic systems: the band structure of trans-polyacetylene

description: A systematic method to account for electron correlation in periodic systems which can predict quantitatively correct band structures of non-conducting solids from first principles is presented. Using localized Hartree-Fock orbitals (both occupied and virtual ones), an effective Hamiltonian is built up whose matrix elements can easily be transferred from finite to infinite systems. To describe the correlation effects wave-function-based multireference configuration interaction (MRCI) calculations with singly and doubly excited configurations are performed. This way it is possible to generate, both, valence and conduction bands with all correlation effects taken into account. Trans-polyacetylene is chosen as a test system.

description: Today's consumer goods markets are rapidly evolving with significant growth in the number of information media as well as the number of competitive products. In this environment, obtaining a quantitative grasp of heterogeneous interactions of firms and customers, which have attracted interest of management scientists and economists, requires the analysis of extremely high-dimensional data. Existing approaches in quantitative research could not handle such data without any reliable prior knowledge nor strong assumptions. Alternatively, we propose a novel method called complex Hilbert principal component analysis (CHPCA) and construct a synchronization network using Hodge decomposition. CHPCA enables us to extract significant comovements with a time lead/delay in the data, and Hodge decomposition is useful for identifying the time-structure of correlations. We apply this method to the Japanese beer market data and reveal comovement of variables related to the consumer choice process across multiple products. Furthermore, we find remarkable customer heterogeneity by calculating the coordinates of each customer in the space derived from the results of CHPCA. Lastly, we discuss the policy and managerial implications, limitations, and further development of the proposed method.

description: Recommendation 58 of the Victorian Royal Commission into Family Violence calls for Victoria Police to trial and evaluate the use of body worn cameras (BWCs) to digitally record evidence- in-chief statements of family violence victims. Although many Australian and international jurisdictions have trialled police BWCs, the evidence base for the effectiveness of police BWCs to gather recorded video evidence is still in its infancy. This project brief draws together findings from a range of studies, including police BWC general duties literature, to provide an overview of current knowledge of police BWCs and the collection of video- recorded evidence in the context of family violence.

description: The two-dimensional Ising model is representable as a lattice free-fermion field theory in terms of the integral over anticommuting Grassmann variables. The exact solution in a zero magnetic field then follows by evaluating Gaussian fermionic integral for partition function. It is argued that by switching on of a non-zero magnetic field the non-local and non-Gaussian fermionic terms appear in the action, which rather imply approximating methods of the analysis.

Healthy ecosystems are those that are stable and sustainable, able to maintain their organization and autonomy over time while remaining resilient to stress (Costanza 1992). Healthy forests are vital to our future (Edmonds and others 2011), and consistent, large-scale, and long-term monitoring of key indicators of forest health status, change, and trends is necessary to identify forest resources deteriorating across large regions (Riitters and Tkacz 2004). The Forest Health Monitoring (FHM) program of the Forest Service, U.S. Department of Agriculture, with cooperating researchers within and outside the Forest Service and with State partners, quantifies status and trends in the health of U.S. forests. The analyses and results outlined in sections 1 and 2 of this FHM annual national report offer a snapshot of the current condition of U.S. forests from a national or multi-State regional perspective, incorporating baseline investigations of forest ecosystem health, examinations of change over time in forest health metrics, and assessments of developing threats to forest stability and sustainability. For datasets collected on an annual basis, analyses are presented from 2017 data. For datasets collected over several years, analyses are presented at a longer temporal scale. Finally, section 3 of this report presents summaries of results from recently completed Evaluation Monitoring (EM) projects that have been funded through the FHM national program to determine the extent, severity, and/or causes of specific forest health problems (FHM 2018).

On the Mass-to-Light Ratio of Large Scale Structure

description: We examine the dependence of the mass-to-light (M/L) ratio of large-scale structure on cosmological parameters, in models that are constrained to match observations of the projected galaxy correlation function w(rp). For a sequence of cosmological models with a fixed P(k) shape and increasing normalization \sig8, we find parameters of the galaxy halo occupation distribution (HOD) that reproduce SDSS measurements of w(rp) as a function of luminosity. Using these HOD models we calculate mean M/L ratios as a function of halo mass and populate halos of N-body simulations to compute M/L in larger scale environments, including cluster infall regions. For all cosmological models, the M/L ratio in high mass halos or high density regions is approximately independent of halo mass or smoothing scale. However, the "plateau" value of M/L depends on \sig8 as well as Ω_m, and it represents the universal mass-to-light ratio only for models in which the galaxy correlation function is approximately unbiased, i.e., with \sig8 ~ \sig8_gal. Our results for cluster mass halos follow the trend M/L = 577(Ω_m/0.3)(\sig8/0.9)^{1.7} h Msun/Lsun. Combined with Carlberg et al.'s (1996) mean M/L ratio of CNOC galaxy clusters, this relation implies (\sig8/0.9)(Ω_m/0.3)^{0.6} = 0.75 +/- 0.06. M/L ratios of clusters from the SDSS and CAIRNS surveys yield similar results. This constraint is inconsistent with parameter values Ω_m ~ 0.3, \sig8 ~ 0.9 favored by recent joint analyses of CMB measurements and other large-scale structure data. We discuss possible resolutions, none of which seems entirely satisfactory. Appendices present an improved formula for halo bias factors and an improved analytic technique for calculating the galaxy correlation function from a given cosmological model and HOD. (Abridged)

description: We are developing the super broad band interferometer by applying the Fourier Transform Spectrometer(FTS) to aperture synthesis system in mm and sub-mm bands. We have constructed a compact system based on the Martin and Puplett type Fourier Transform spectrometer (MP-FT). We call this equipment Multi-Fourier Transform interferometer (MuFT). The band width of the system can be extended as large as one wants contrary to the severely limited band width of the usual interferometer due to the speed of the AD converter. The direct detectors, e.g. bolometer, SIS video detector, can be used as the focal plane detectors. This type of detectors have a great advantage in FIR band since they are free from the quantum limit of the noise which limits the sensitivity of the heterodyne detectors used in the usual interferometers. Further, the direct detectors are able to make a large format array contrary to the heterodyne detectors for which construction of a large format array is practically difficult. These three characteristics make one be possible to develop high sensitive super broad band FIR interferometer with wide field of view. In the laboratory experiments, we have succeeded in measuring the spectroscopically resolved 2D image of the source in 150GHz-900GHz band. The future application of this technique to the observations from the space could open new interesting possibilities in FIR astronomy.

Expression of αvβ6 integrin in the junctional epithelium
Creators: name: Garcia Fulle, Maria Isabel
Publisher: name: University of British Columbia
Year: 2009

description: Cell-cell binding and cell-extracellular matrix adhesion is mediated by cell surface receptors known as integrins, which play important roles during wound healing. Junctional epithelium (JE) that links gingiva to tooth enamel mimics wound epithelium. The αvβ6 integrin is an epithelial integrin that is not normally expressed by oral gingival epithelium but is induced during wound healing, and has also been shown to be expressed in squamous cell carcinomas and in leukoplakia specimens. Furthermore, αvβ6 integrin can bind and activate transforming growth factor-β (TGF-β), suggesting a central role for the integrin in this unique epithelium. Using human gingival specimens from extracted teeth and human gingival specimens attached to decalcified teeth, the presence of JE was confirmed using simple epithelia tissue markers (cytokeratin-19 and laminin-5). The presence of αvβ6 integrin in the JE and some of its putative ligands (such as tenascin, fibronectin and TGF-β) was confirmed using immunohistochemical labelling. Paraffin sections of wild-type (FVB), β6integrin-overexpressing (B6F1) and P6integrin-knock-out mice (β6-/-) were stained with hematoxylin and eosin and observed under the light microscope to analyze the morphology of the JE. Interestingly, the analysis of the β6-/- sections showed striking alterations in the morphology and cellular organization of the JE. The findings of this study suggest that αvβ6 integrin is constitutively expressed in the JE, in which it could function as an immunoregulator via activation of TGF-β1.

description: Machine learning-based surrogate models have become the preferred approach for large-scale and frequent simulation tasks due to its significant improvement in computational efficiency. In order to overcome the potential effects of learning with small sample data and the challenges of multi-feature multi-task learning, we developed a novel deep learning long short-term memory (LSTM) model. Taking slope excavation displacement prediction as a case study, we employed the Latin hypercube sampling method to generate a synthetic dataset for training LSTM and other mainstream models. Experimental results demonstrate that the model's prediction accuracy decreases with a reduction in sample size, while support vector regression (SVR), back propagation neural network (BPNN), LSTM and Gaussian process regression (GPR) demonstrate a stronger resistance. It is feasible to utilise excavation features as model inputs to establish a unified multi-step excavation model, but the accuracy of the SVR model decreased by 32.5% after supplementing excavation features. Even when the sample size is less than 50, both LSTM and GPR exhibit excellent performance, achieving model R-squared and RMSE surpassing 0.99 and 0.07 mm. However, when addressing multi-output learning tasks, LSTM stands out as the optimal choice. This study will assist researchers or engineers in swiftly selecting appropriate surrogate models.

description: It is proposed to improve the quality of a variational description of a closed quantum system by adding ficticious dissipation that reduces the entanglement. The proposal is implemented for a small Bose-Hubbard chain, which shows chaotic behavior and associated fast growth of quantum fluctuations. For appropriately chosen dissipation, good agreement with the truncated Wigner approximation (which is very accurate for the chosen system parameters) is found.

description: The paper presents a theory of policy timing that relies on uncertainty and transaction costs to explain the optimal timing and length of policy reforms. Delaying reforms resolves some uncertainty by gaining valuable information and saves transaction costs. Implementing reforms without waiting increases welfare by adjusting domestic policies to changed market parameters. Optimal policy timing is found by balancing the trade-off between delaying reforms and implementing reforms without waiting. Our theory offers an explanation of why countries differ with respect to the length of their policy reforms, and why applied studies often judge agricultural policies to be inefficient.

description: This thesis explores the ethical dimensions of different science fiction (SF) traditions, bringing SF studies into dialogue with poststructuralist literary theory and Emmanuel Levinas’s writings on ethics. US pulp SF, Eastern European SF, and post-New-Wave SF traditions are examined through case studies of Isaac Asimov, Yevgeny Zamyatin, and Gene Wolfe. It is argued that US pulp SF’s representation of the world, and other people, reveal totalising foundations that result in problematic ethical and political orientations. SF beyond this influential genre tradition, however, has demonstrated the potential for SF to engage with more ethical approaches to alterity, unknowability and the other.

description: We provide a complete classification of asymptotic quasinormal frequencies for static, spherically symmetric black hole spacetimes in d dimensions. This includes all possible types of gravitational perturbations (tensor, vector and scalar type) as described by the Ishibashi-Kodama master equations. The frequencies for Schwarzschild are dimension independent, while for RN are dimension dependent (the extremal RN case must be considered separately from the non-extremal case). For Schwarzschild dS, there is a dimension independent formula for the frequencies, except in dimension d=5 where the formula is different. For RN dS there is a dimension dependent formula for the frequencies, except in dimension d=5 where the formula is different. Schwarzschild and RN AdS black hole spacetimes are simpler: the formulae for the frequencies will depend upon a parameter related to the tortoise coordinate at spatial infinity, and scalar type perturbations in dimension d=5 lead to a continuous spectrum for the quasinormal frequencies. We also address non-black hole spacetimes, such as pure dS spacetime--where there are quasinormal modes only in odd dimensions--and pure AdS spacetime--where again scalar type perturbations in dimension d=5 lead to a continuous spectrum for the normal frequencies. Our results match previous numerical calculations with great accuracy. Asymptotic quasinormal frequencies have also been applied in the framework of quantum gravity for black holes. Our results show that it is only in the simple Schwarzschild case which is possible to obtain sensible results concerning area quantization or loop quantum gravity. In an effort to keep this paper self-contained we also review earlier results in the literature.

description: Using a modified Fisher-Seater model with consideration of policy impacts, this paper attempts to tests the long-run neutrality of money supply on food prices in Germany after the launching of the Eurozone. The main findings include: (1) we can not reject the super neutrality of money for aggregated food prices; (2) However, staple food and its derived products – meat- are very sensitive to money supply, and their prices can increase to be much higher than money growth rate, perhaps due to speculative effects and demand effects; (3) Fresh or perishable products are usually less sensitive to money growth; (4) Most products decreased their prices after the launching of decoupling policy in Europe in 2003. The results can explain the links between money supply and food prices in a long run and also give insightful implications for the ongoing reform of CAP (Common Agricultural Policy) in Europe.

description: Shorefast sea ice provides an important platform for winter and spring travel between coastal Arctic communities unconnected by road networks. In the past two decades, local Arctic residents have reported thinning and earlier breakup of shorefast ice. Despite these assertions, however, there are few quantitative assessments of how these changes have impacted travel on sea ice. In this study, we use high-resolution satellite remote sensing and transportation modeling to assess snow mobile travel in Uummannaq Fjord, Greenland. Following classification of satellite imagery, we generate optimal least-cost travel routes according to surface types present in the fjord. We then estimate distance and duration of snowmobile travel potential between communities from 1985 through 2019. We find that snowmobile travel in Uummannaq Fjord has potentially become slower and more unpredictable in recent years (2014–2019) relative to thirty years prior (1985–2000), with greater changes for communities located more proximal to the shorefast ice edge. Our results also suggest that reductions in on-ice snow cover impede snowmobile travel more than fractures do. Overall, our analysis demonstrates how remote sensing and transportation modeling may be used to quantify the community-scale impacts of changing shorefast ice conditions and has potential to help manage localized climate-related risk.

description: We consider the problem of estimating a network's eigenvector centrality only from data on the nodes, with no information about network topology. Leveraging the versatility of graph filters to model network processes, data supported on the nodes is modeled as a graph signal obtained via the output of a graph filter applied to white noise. We seek to simplify the downstream task of centrality ranking by bypassing network topology inference methods and, instead, inferring the centrality structure of the graph directly from the graph signals. To this end, we propose two simple algorithms for ranking a set of nodes connected by an unobserved set of edges. We derive asymptotic and non-asymptotic guarantees for these algorithms, revealing key features that determine the complexity of the task at hand. Finally, we illustrate the behavior of the proposed algorithms on synthetic and real-world datasets.

description: We introduce a new formulation of baryon chiral perturbation theory which improves the ultraviolet behavior of propagators and can be interpreted as a smooth cutoff regularization scheme. It is equivalent to the standard approach, preserves all symmetries and therefore satisfies the Ward identities. Our formulation is equally well defined in the vacuum, one- and few-nucleon sectors of the theory. The equations (Bethe-Salpeter, Lippmann-Schwinger, etc.) for the scattering amplitudes of the few-nucleon sector are free of divergences in the new approach. Unlike the usual cutoff regularization, our 'cutoffs' are parameters of the Lagrangian and do not have to be removed.

description: This study explores dissimilarity in food culture (food culture distance) as an antecedent to the adaptation of export marketing strategy for food products, and examines the impact of marketing program adaptation on export performance. Building on previous research, this paper introduces a model for operationalizing the construct food culture distance. Data were gathered via a mail survey of Swedish and Finnish food exporters. The results indicate a significant correlation between food culture distance and the extent of product adaptation. However, product adaptation does not affect export performance, implying that other factors, along with marketing strategy, may influence export performance.

description: Soil liquefaction has garnered significant research attention over several decades due to its profound impact on infrastructure systems in earthquake-prone regions. Given the limitations inherent in the assumptions and approximations of conventional methods, machine learning has emerged as a robust and efficient approach for predicting soil liquefaction potential. This study aims to develop a synergistic JS-CNN-XGB model, unifying the Jellyfish Search (JS) optimizer with a hybrid deep/machine learning model. This amalgamation leverages the feature extraction capabilities of the Convolutional Neural Network (CNN) alongside the classification prowess of the eXtreme Gradient Boosting (XGB) algorithm. The proposed model seamlessly integrates into a user-friendly prediction system, streamlining the liquefaction prediction process. Validation is achieved through case studies involving historical earthquake recordings with diverse classification ratios and varying input attribute quantities. Compared to existing studies, our proposed system showcases a notable 6.2% enhancement in overall liquefaction assessment accuracy, demonstrating improved detection capabilities in imbalanced and balanced datasets. In conclusion, this study underscores an automated system that presents a robust solution to the challenges posed by liquefaction potential assessment in geotechnical engineering.

description: It has been shown recently that there is a large class of supersymmetric solutions of five-dimensional supergravity which generalize the supersymmetric black ring solution of Elvang et al. This class involves arbitrary functions. We show that most of these solutions do not have smooth event horizons, so they do not provide examples of black objects with infinite amounts of "hair".

description: The Produce Traceability Initiative (PTI) was created by a coalition of fresh produce industry leaders as a voluntary industry effort to improve supply chain traceability, expedite tracebacks and recalls, and isolate food safety problems when they occur. In this paper we assess the ability of the PTI to meet broad traceability goals and make recommendations for guidelines that should be followed for an effective traceback system. Our recommendations include principles for system-wide uniformity, standardization of product reference numbers, creation of a reporting mechanism, and open and transparent communication.

description: Let $X$ be a finite connected graph, each of whose vertices has degree at least three. The fundamental group $Γ$ of $X$ is a free group and acts on the universal covering tree $Δ$ and on its boundary $\partial Δ$, endowed with a natural topology and Borel measure. The crossed product $C^*$-algebra $C(\partial Δ) \rtimes Γ$ depends only on the rank of $Γ$ and is a Cuntz-Krieger algebra whose structure is explicitly determined. The crossed product von Neumann algebra does not possess this rigidity. If $X$ is homogeneous of degree $q+1$ then the von Neumann algebra $L^\infty(\partial Δ)\rtimes Γ$ is the hyperfinite factor of type $III_λ$ where $λ=1/{q^2}$ if $X$ is bipartite, and $λ=1/{q}$ otherwise.
Supernovae in Helium Star--Compact Object Binaries: A Possible Gamma-ray Burst Mechanism
Creators: name: Broderick, Avery E.

description: Helium star--compact object binaries, and helium star--neutron star binaries in particular, are widely believed to be the progenitors of the observed double neutron star systems. In these, the second neutron star is presumed to be the compact remnant of the helium star supernova. Here, the observational implications of such a supernova are discussed, and in particular are explored as a candidate gamma-ray burst mechanism. In this scenario the supernova results in a transient period of rapid accretion onto the compact object, extracting via magnetic torques its rotational energy at highly super-Eddington luminosities in the form of a narrowly beamed, strongly electromagnetically dominated jet. Compton scattering of supernova photons advected within the ejecta, and photons originating at shocks driven into the ejecta by the jet, will cool the jet and can produce the observed prompt emission characteristics, including the peak--inferred isotropic energy relation, X-ray flash characteristics, subpulse light curves, energy dependent time lags and subpulse broadening, and late time spectral softening. The duration of the burst is limited by the rate of Compton cooling of the jet, eventually creating an optically thick, moderately relativistically expanding fireball which can produce the afterglow emission. If the black hole or neutron star stays bound to a compact remnant, late term light curve variability may be observed as in SN 2003dh.

Toxicities of thymol, citronellal, eugenol and rosemary oil to control Agriotes obscurus (Coleoptera: Elateridae) in laboratory and greehouse bioassays
Creators: name: Waliwitiya, Ranil
Publisher: name: University of British Columbia
Year: 2009

description: Toxicities were determined for four naturally occurring monoterpenoid essential oils on late instar larvae of Agriotes obscurus in laboratory and greenhouse bioassays. Both contact and fumigant toxicities were determined for thymol, citronellal, eugenol and rosemary oil. Thymol had the greatest contact toxicity (LD₅₀=196.0 μg/larva) while citronellal and eugenol were significantly less toxic (LD₅=404.9 μg/larva and 516.5 μg/larva, respectively). Rosemary oil did not show any significant contact toxicity, at the highest dose tested, 1600 μg/larva. In fumigant bioassays, citronellal was the most toxic to wireworm larvae (LD₅=6.3 μg/cm ) followed by rosemary oil (LD₅=15.7 μg/cm ), thymol (LD₅=16.9 μg/cm³), and eugenol (LD₅=20.8 μg/cm³). Phytotoxicities were also evaluated based on corn seed germination and seedling development. In laboratory bioassays, thymol and citronellal significantly inhibited seed germination and development while rosemary oil had only minimal phytotoxic effects. Based on these laboratory results, four treatments were selected for repellency trials under greenhouse conditions. Citronellal (800 pg/seed), thymol (400 μg/seed), rosemary oil (1600 μg/seed) and eugenol (1600 pg/seed) were evaluated for their ability to protect corn seeds from Agriotes obscurus feeding damage. In the bioassay, wireworm health, seed germination, seed damage, and seedling height were evaluated. Rosemary oil treated seeds produced the highest number of distressed wireworms (56%, Odds Ratio = 2.64) compared to all other treatments while not creating any phytotoxic effects. Seeds treated with thymol were the least damaged (90.7% undamaged, Odds Ratio = 0.153) compared to the control while thymol and citronellal retarded seedling height compared to the control. Eugenol produced the lowest seed germination (25.3% germination) while citronellal, rosemary oil and thymol had no negative impact on seed germination.
New Gamma-Ray Bursts Found in the Archival Data from the IBIS/ISGRI Telescope of the INTEGRAL Observatory

description: A systematic search for cosmic gamma-ray bursts (GRBs) and other short hard X-ray events in the archival data from the IBIS/ISGRI telescope of the INTEGRAL observatory over 2003-2018 has been carried out. Seven previously unknown GRBs have been recorded in the telescope field of view; all of them have been localized with an accuracy < 2 arcmin. These events were not revealed by the INTEGRAL burst alert system (IBAS) designed for an automatic GRB search and alert. Four more such localized events missed by IBAS, but known previously, i.e., observed in other experiments, have been found. Eight hundred and eighty six GRBs outside the field of view that arrived at large angles to the IBIS/ISGRI axis have also been recorded. All of them were previously recorded in other experiments, primarily by the anticoincidence shield (ACS) of the SPI gamma-ray spectrometer onboard INTEGRAL, the PICsIT detector of the IBIS gamma-ray telescope, and the KONUS/WIND monitor. An order of magnitude more events without any confirmations in other experiments have been recorded. Both GRBs and solar flares or magnetospheric transient events can be among them. Catalogs with the basic parameters of confirmed and previously unknown GRBs recorded by IBIS/ISGRI have been compiled. The statistical distributions of bursts in various parameters have been constructed and investigated.
