description: The notions of reflection from outside, reflection from inside and signature of a billiard trajectory within a quadric are introduced. Cayley-type conditions for periodical trajectories for the billiard in the region bounded by $k$ quadrics in $R^d$ and for the billiard ordered game within $k$ ellipsoids in $R^d$ are derived. In a limit, the condition describing periodic trajectories of billiard systems on a quadric in $R^d$ is obtained.

description: This paper outlines our recent attempts to model the growth and form of microbialites from the perspective of the statistical physics of evolving surfaces. Microbialites arise from the environmental interactions of microbial communities (microbial mats). The mats evolve over time to form internally laminated organosedimentary structures (stromatolites). Modern day stromatolites exist in only a few locations, whereas ancient stromatolitic microbialites were the only form of life for much of the Earth's history. They existed in a wide variety of growth forms, ranging from almost perfect cones to branched columnar structures. The coniform structures are central to the heated debate on the oldest evidence of life. We proposed a biotic model which considers the relationship between upward growth of a phototropic or phototactic biofilm and mineral accretion normal to the surface. These processes are sufficient to account for the growth and form of many ancient stromatolities. These include domical stromatolites and coniform structures with thickened apical zones typical of Conophyton. More angular coniform structures, similar to the stromatolites claimed as the oldest macroscopic evidence of life, form when the photic effects dominate over mineral accretion.

description: We find that the temperature dependence of the drag resistivity ($ρ_{D}$) between two dilute two-dimensional hole systems exhibits an unusual dependence upon spin polarization. Near the apparent metal-insulator transition, the temperature dependence of the drag, given by $T^α$, weakens with the application of a parallel magnetic field ($B_{||}$), with $α$ saturating at half its zero field value for $B_{||} > B^{*}$, where $B^{*}$ is the polarization field. Furthermore, we find that $α$ is roughly 2 at the parallel field induced metal-insulator transition, and that the temperature dependence of $ρ_{D}/T^{2}$ at different $B_{||}$ looks strikingly similar to that found in the single layer resistivity. In contrast, at higher densities, far from the zero field transition, the temperature dependence of the drag is roughly independent of spin polarization, with $α$ remaining close to 2, as expected from a simple Fermi liquid picture.

description: The theme of this paper is the derivation of analytic formulae for certain large combinatorial structures. The formulae are obtained via fluid limits of pure jump-type Markov processes, established under simple conditions on the Laplace transforms of their Levy kernels. Furthermore, a related Gaussian approximation allows us to describe the randomness which may persist in the limit when certain parameters take critical values. Our method is quite general, but is applied here to vertex identifiability in random hypergraphs. A vertex v is identifiable in n steps if there is a hyperedge containing v all of whose other vertices are identifiable in fewer steps. We say that a hyperedge is identifiable if every one of its vertices is identifiable. Our analytic formulae describe the asymptotics of the number of identifiable vertices and the number of identifiable hyperedges for a Poisson(β) random hypergraph Λon a set V of N vertices, in the limit as N\to \infty. Here βis a formal power series with nonnegative coefficients β_0,β_1,..., and (Λ(A))_{A\subseteq V} are independent Poisson random variables such that Λ(A), the number of hyperedges on A, has mean Nβ_j/\pmatrixN j whenever |A|=j.

description: This paper analyzes the wheat market in South America, with a focus on MERCOSUR. It argues that wheat markets in South America have undergone significant changes over the last decade, driven by the world macroeconomic and agricultural cycle of the last quarter of the century, as well as specific economic and sectoral policies in the region. Latin America's economic environment is now characterized by fiscal constraints and greater price stability, market liberalization and trade openness. In this new setting, Argentina has consolidated its position as a net exporter, due to both increased production and stagnant or even declining consumption, while Brazil and the rest of South America, with opposite trends in production and consumption, are increasing their net imports of wheat.These supply and demand changes, along with greater trade liberalization, are reshaping trade patterns in the region, increasing Argentina's exports to Brazil and the rest of South America. This trade environment will continue to change due to the phasing in of WTO disciplines, and the possible expansion of regional trade agreements. Wheat trade issues that in the past focused prominently on export subsidies and trade practices of state trading enterprises may, in the future, be more related to sanitary and phytosanitary practices or to controversies linked to wheat flour and wheat-based manufactured goods, rather than to the primary product. Besides trade and agricultural sector policies affecting directly the primary sector, other aspects to be considered for future patterns in wheat production, consumption and trade, are the evolution of the milling, bakery, pasta and related industries in Brazil and Argentina, and different macroeconomic policies in both countries, particularly regarding exchange rate regimes.

A decomposition analysis is undertaken on the changes in price competitiveness of four major nonrice crops in Indonesia between subperiods during 19870-1994. An important conclusion is that, after the attainment of rice self-sufficiency, Indonesian policies have not promoted crop diversification on a "level playing field."

description: We exploit rare observations covering the time before and during a normal outburst in the deeply-eclipsing SU UMa system IY UMa to study the dramatic changes in the accretion flow and emission at the onset of outburst. Through Doppler tomography we study the emission distribution, revealing classic accretion flow behaviour in quiescence, with the stream-disc impact ionizing the nearby accretion disc. We observe a delay of hours to a couple of days between the rise in continuum and the rise in the emission lines at the onset of the outburst. From line profiles and Doppler maps during normal and superoutburst we conclude that reprocessing of boundary layer radiation is the dominant emission line mechanism in outburst, and that the normal outburst began in the outer disc. The stream-disc impact feature (the `orbital hump') in the H alpha line flux light curve disappears before the onset of the normal outburst, and may be an observable signal heralding an impending outburst.

description: A reliable single photon source is a prerequisite for linear optical quantum computation and for secure quantum key distribution. A criterion yielding a conclusive test of the single photon character of a given source, attainable with realistic detectors, is therefore highly desirable. In the context of heralded single photon sources, such a criterion should be sensitive to the effects of higher photon number contributions, and to vacuum introduced through optical losses, which tend to degrade source performance. In this paper we present, theoretically and experimentally, a criterion meeting the above requirements.

description: In this paper, we develop and analyze a trilinear immersed finite element method for solving three-dimensional elliptic interface problems. The proposed method can be utilized on interface-unfitted meshes such as Cartesian grids consisting of cuboids. We establish the trace and inverse inequalities for trilinear IFE functions for interface elements with arbitrary interface-cutting configuration. Optimal a priori error estimates are rigorously proved in both energy and L2 norms. Numerical examples are provided not only to verify our theoretical results but also to demonstrate the applicability of this IFE method in tackling some real-world 3D interface models.
The nature and function of the Buddhist and Ru teachings in Li Daochun’s (fl. ca. 1288) Wondrous Way of Peerless Orthodox Truth
Creators: name: Crowe, Paul Benjamin Michael
Publisher: name: University of British Columbia
Year: 2009

description: This study examines of the way of cultivation taught by Li Daochun (fl. ca. 1288) and preserved by him and several of his disciples in two lengthy works: Qingan yingchan zi yulu (Dialogic Treatise of Master Qingan yingchan) and the Zhonghe ji (Anthology on the Centre and Harmony). Li describes his teaching as the "Wondrous Way of Peerless Orthodox Truth" and claims that great teachers have transmitted it wordlessly down through the ages. Further, it lies at the heart of the Three Teachings: Buddhist, Ru literati, and Daoist. This "Wondrous Way," being fundamentally beyond words, simultaneously exists outside the confines of the "Three Teachings." It is well known among scholars studying the many varied facets of what is referred to generally as "Taoism" that teachers such as Li Daochun, who described themselves as Golden Elixir (jindan) adepts, also represented themselves as unifiers of the Three Teachings. It has often been noted that Golden Elixir texts show evidence of influence from Buddhism, (Chan Buddhism in particular) and from ideas associated with the way of personal cultivation taught by Confucius and Mencius, and later reinvented by Ru literati of the Song and Yuan dynasties and, at the close of the thirteenth century, unified by Zhu Xi (1130-1200) under the designation "Daoxue" (Teaching of the Way). Employing translated material from the two texts mentioned above, this study enriches these observations with greater detail concerning the precise nature of the influences, both in terms of their provenance and the way in which Li has reinterpreted and incorporated these "Teachings" into his way of cultivation. This added detail sheds light on what Li thought the labels "Buddhist Teaching" and "Ru Teaching" represented. By examining exactly how these teachings were adapted to Li Daochun's "Wondrous Way of Peerless Orthodox Truth" insight is also gained into Li's formation of his own identity. He demonstrates a high degree of facility with a variety of Buddhist doctrines and the Daoxue approach to cultivation as uses his impressive understanding to mould the "Teachings" to his own purposes. Ultimately, Li's project of "unification" rests on his efforts at recreation.

description: [...] We turn then to the theoretical developments in the short GRBs: we first report some progress in the understanding the dynamical phase of collapse, the mass-energy formula and the extraction of blackholic energy which have been motivated by the analysis of the short GRBs. In this context progress has also been accomplished on establishing an absolute lower limit to the irreducible mass of the black hole as well as on some critical considerations about the relations of general relativity and the second law of thermodynamics. We recall how this last issue has been one of the most debated in theoretical physics in the past thirty years due to the work of Bekenstein and Hawking. Following these conceptual progresses we analyze the vacuum polarization process around an overcritical collapsing shell. We evidence the existence of a separatrix and a dyadosphere trapping surface in the dynamics of the electron-positron plasma generated during the process of gravitational collapse. We then analyze, using recent progress in the solution of the Vlasov-Boltzmann-Maxwell system, the oscillation regime in the created electron-positron plasma and their rapid convergence to a thermalized spectrum. We conclude by making precise predictions for the spectra, the energy fluxes and characteristic time-scales of the radiation for short-bursts. If the precise luminosity variation and spectral hardening of the radiation we have predicted will be confirmed by observations of short-bursts, these systems will play a major role as standard candles in cosmology. These considerations will also be relevant for the analysis of the long-bursts when the baryonic matter contribution will be taken into account.

description: This review critically examines strain theory, a prominent sociological framework for understanding deviance and violence. We discussed an overview of strain theory and defined school violence. The theoretical framework section explains strain theory, its application to school violence, and the factors contributing to strain in schools. The impact of strain theory on school violence is examined in the following section, which discusses the link between strain and aggressive behavior, the role of strain in the development of violent tendencies, and the effects of strain on academic performance and social relationships. This section also includes case studies illustrating the connection between strain and school violence. Finally, the article concludes with prevention and intervention strategies, emphasizing the importance of early identification and intervention, the implementation of supportive programs and resources, collaboration between schools, families, and communities for prevention, and evaluating prevention strategies and their effectiveness

description: This study introduces two advances to the aggregate productivity index methodology typically employed by ABARES. First, it accounts for the effects of climate variability on measured productivity by matching spatial climate data to individual farms in the ABARES farm surveys database. Second, a farm-level production frontier estimation technique is employed to facilitate the decomposition of productivity change into several key components, including technical change and technical efficiency change. The study makes use of farm-level data from the ABARES Australian agricultural and grazing industries survey database. An unbalanced panel dataset is constructed containing 13 430 observations (4255 farms) over the period 1977–78 to 2007–08. Spatial climate data, including winter and summer seasonal rainfall and average maximum and minimum temperatures, were obtained via the Australian Water Availability Project. These data were mapped to individual farms using Geographic Information System methods. The study employed stochastic frontier analysis methods to estimate a production frontier with time varying technical efficiency effects of the form proposed by Battese and Coelli (1992). Production frontiers are estimated for each of the three major Grains Research and Development Corporation regions: southern, northern and western. Selected climate variables are shown to display a high degree of explanatory power over farm output. The results confirm that deterioration in average climate conditions has contributed significantly to the decline in estimated productivity over the post-2000 period. Technical change is shown to be the primary driver of productivity growth in the industry in the long run, offset by a gradual decline in technical efficiency. After controlling for climate variability, a gradual decline in the rate of technical change is still observed.
Molecular and biochemical characterization of viral and vector components required for cucumber necrosis virus transmission
Creators: name: Kishore Kakani, Naga
Publisher: name: University of British Columbia
Year: 2009

description: Natural transmission of Cucumber necrosis virus (CNV) occurs via zoospores of the chytrid fungus Olpidium bornovanus. Transmission involves specific adsorption of virus particles onto the zoospore plasmalemma prior to infestation of cucumber roots by virus bound zoospores. In order to determine if specific regions of the CNV capsid are involved in transmission, several naturally occurring CNV transmission mutants were isolated and characterized. Analysis of the mutants showed that the CNV trimer cavity at the particle quasi three-fold axis plays an important role in transmission, and, moreover that the reduction in transmission is at least partially due to the reduced ability of mutants to bind to zoospores. In vitro virus/zoospore binding studies have shown that pre-treatment of zoospores with trypsin and sodium periodate each decrease CNV binding by approximately 80%, whereas no reduction in binding was found when zoospores were treated with phospholipase C. These studies suggest an important role for zoospore proteins and/or glycoprotein(s) in virus attachment. In virus overlay assays, CNV virions bound to specific-sized zoospore proteins, but CNV transmission mutants showed little or reduced binding. Several sugars were used to study their inhibitory potential on CNV binding to zoospores in vitro. It was found that a variety of mannose-containing sugars inhibited CNV binding to zoospores whereas several others did not. These studies suggest that the putative zoospore receptor may be a mannose-containing glycoprotein. Many animal virus particles undergo conformational changes upon binding to their cellular receptors. CNV is an icosahedral virus and like many other isometric plant viruses, undergoes expansion in the presence of EDTA at an alkaline pH. In the case of CNV, we have demonstrated that during expansion, the internally located coat protein RNA binding domain (R) and arm domains translocate to the particle exterior, becoming protease sensitive. Protease digestion experiments of zoospore-bound virus have revealed that CNV undergoes conformational change upon binding to zoospores and that the conformationally altered virion resembles the swollen conformation. In addition, we have found that a CNV mutant defective in vector transmission is unable to undergo this conformational change. This is the first time that conformational change in a plant virus particle has been shown to be essential for vector transmission.
Estimating irrigation farm production functions using ABARES irrigation survey data

description: The ABARE (now ABARES) survey of irrigation farms in the Murray–Darling Basin began in 2006–07 and provides a comprehensive farm-level panel dataset, which, to date, has seen limited econometric analysis (Ashton et al. 2009). At present, three complete years of irrigation survey data are available: 2006–07, 2007–08 and 2008–09. In each year, approximately 850 farms are sampled. As with the ABARES broadacre surveys, the irrigation survey is a rotating (unbalanced) panel dataset. This study makes use of the irrigation survey data to estimate production functions at both the farm and enterprise (crop/livestock activity) level. In addition to the traditional categories of input use (land, labour, capital and materials), the study incorporates measures of water use, tree and vine capital and local seasonal rainfall. The analysis incorporates fixed effects models to take advantage of the survey’s panel structure, as well as consideration of potentially endogenous inputs via instrumental variable methods. The study focuses on the short-run marginal revenue product of water implied by the estimated production functions. The results provide an encouraging demonstration of the kind of analysis that can be undertaken with the irrigation survey dataset. The estimated marginal product curves showed horticulture farms to have the steepest marginal product curve and broadacre farms to have the most elastic. There remain a number of promising areas for potential future research using the dataset, particularly if the survey were to continue for a longer and more representative sample of years.

description: A binary compact object early in its inspiral phase will be picked up by its nearly monochromatic gravitational radiation by LISA. But even this innocuous appearing candidate poses interesting detection challenges. The data that will be scanned for such sources will be a set of three functions of LISA's twelve data streams obtained through time-delay interferometry, which is necessary to cancel the noise contributions from laser-frequency fluctuations and optical-bench motions to these data streams. We call these three functions pseudo-detectors. The sensitivity of any pseudo-detector to a given sky position is a function of LISA's orbital position. Moreover, at a given point in LISA's orbit, each pseudo-detector has a different sensitivity to the same sky position. In this work, we obtain the optimal statistic for detecting gravitational wave signals, such as from compact binaries early in their inspiral stage, in LISA data. We also present how the sensitivity of LISA, defined by this optimal statistic, varies as a function of sky position and LISA's orbital location. Finally, we show how a real-time search for inspiral signals can be implemented on the LISA data by constructing a bank of templates in the sky positions.

description: This paper examines broadacre farm performance in south-western Australia. This region has experienced pronounced climate variability and volatile commodity prices over the last decade or so. Relationships between productivity and profitability are explored using panel data from 50 farms in the study region. The data are analysed using non-parametric methods. Components of farm productivity and profitability are measured over the period 1998 to 2008. Economies of scale and scope are shown often to be positive contributors to productivity and profitability. However, the main finding is that technical change, much more so than technical efficiency, has supplied over 68 percent of the improvement in total factor productivity for farms in the different climatic zones of the region from 1998 to 2008. In addition, growth in total factor productivity is the main contributor to farm profitability. By implication, technical change, often accompanied by scale and mix efficiencies, is the main driver of farm profitability. These findings indicate a vital role for innovation and R,D&E to deliver technologies and practices that bolster farm profitability, as well as a continuing role for scale and scope economies. The products and knowledge that come from innovation and R,D&E are the springboard for technical change. Through technical change and scale and scope efficiencies farmers in this study have achieved higher profits.

description: Anthropogenic disturbances lead to the degradation or destruction of tropical forests, with negative consequences for flora, fauna, and local people. Restoration plantings may compensate these impacts, but time and financial expenditures are high. Thus, priority is often given to plantations of a few introduced species that have little value for conservation. Animal seed dispersal may diversify and accelerate regeneration of restoration plantings, thereby lowering their costs. We studied seed dispersal quantity and quality of crowned lemurs (Eulemur coronatus) in a highly degraded forest in northern Madagascar, conducting behavioural observations and germination experiments and describing dispersed plant species’ characteristics. Crowned lemurs were highly frugivorous, dispersing a large number of seeds and plant species. While there were negative effects of gut passage on germination, the positive effects of pulp removal outweighed these, resulting in an overall positive effect on regeneration. Our study confirmed that effects of gut passage are dependent on the dispersed plant species. We found 20 plant species, including three threatened with extinction, whose only dispersers in Oronjia seem to be crowned lemurs. We conclude that lemurs play important roles in protecting plant species and maintaining healthy ecosystems through seed dispersal, and that E. coronatus is a key species in this respect. In addition, if lemurs were included in restoration, they would disperse a diversity of plant species that cannot be matched by conventional restoration plantings. Their influence would facilitate the regeneration of some, but not all plant species. Negative effects, like the spread of invasive species through seed dispersal by lemurs, must also be considered.

description: We consider potential type dynamical systems in finite dimensions with two meta-stable states. They are subject to two sources of perturbation: a slow external periodic perturbation of period $T$ and a small Gaussian random perturbation of intensity $ε$, and, therefore, are mathematically described as weakly time inhomogeneous diffusion processes. A system is in stochastic resonance, provided the small noisy perturbation is tuned in such a way that its random trajectories follow the exterior periodic motion in an optimal fashion, that is, for some optimal intensity $ε(T)$. The physicists' favorite, measures of quality of periodic tuning--and thus stochastic resonance--such as spectral power amplification or signal-to-noise ratio, have proven to be defective. They are not robust w.r.t. effective model reduction, that is, for the passage to a simplified finite state Markov chain model reducing the dynamics to a pure jumping between the meta-stable states of the original system. An entirely probabilistic notion of stochastic resonance based on the transition dynamics between the domains of attraction of the meta-stable states--and thus failing to suffer from this robustness defect--was proposed before in the context of one-dimensional diffusions. It is investigated for higher-dimensional systems here, by using extensions and refinements of the Freidlin--Wentzell theory of large deviations for time homogeneous diffusions. Large deviations principles developed for weakly time inhomogeneous diffusions prove to be key tools for a treatment of the problem of diffusion exit from a domain and thus for the approach of stochastic resonance via transition probabilities between meta-stable sets.

Risk, uncertainty and pasture investment decisions

description: The private decisions of farmers to invest in new technologies interest economists because these decisions influence the rate of farm productivity growth and the returns to public investment in agricultural research and development. Economic analysis of decisions to invest in new technologies on farms involves considering the effects of these decisions on the profitability and risk of the farm business. This is done routinely using whole-farm economic models and techniques such as stochastic simulation. Such analysis can be used to predict the extent to which a technology is likely to be adopted in equilibrium, when the consequences of adoption are known to all potential adopters. Until this equilibrium is reached, however, potential adopters of new technologies face uncertainty about the consequences of adoption. This alters expectations about the effects on profitability and risk of adoption, and hence alters investment decisions. The resolution of uncertainty over time through learning is therefore a key determinant of the rate at which new technologies are adopted, and hence should be represented in dynamic economic models which seek to explain these decisions.

description: The concept of parity-time (PT) symmetry originates from the framework of quantum mechanics, where if the Hamiltonian operator satisfies the commutation relation with the parity and time operators, it shows all real eigen-energy spectrum. Recently, PT symmetry was introduced into optics, electronic circuits, acoustics, and so many other classical fields to further study the dynamics of the Hamiltonian and the energy of the system. Focusing on the dynamical evolution of the quantum state under the action of PT symmetric Hamiltonian, here we experimentally demonstrated the general dynamical evolution of a two-level system under the PT symmetric Hamiltonian using single-photon system. By enlarging the system using ancillary qubits and encoding the subsystem under the non-Hermitian Hamiltonian with post-selection, the evolution of the state can be observed with a high fidelity when the successfully parity-time symmetrically evolved subspace is solely considered. Owing to the effectively operation of the dilation method, our work provides a route for further exploiting the exotic properties of PT symmetric Hamiltonian for quantum simulation and quantum information processing.

description: This thesis explores the role and effectiveness of visual aids in teaching drawing science within general secondary schools. Drawing, as a highly visual subject, requires methods that enhance students' understanding of concepts such as perspective, proportion, and shading. The study investigates various types of visual aids, including traditional tools like models and diagrams, alongside modern digital resources such as interactive software and videos. The research methodology encompasses surveys, classroom observations, and interviews with both teachers and students to assess the impact of these aids on student comprehension and engagement.

description: We suggest a novel concept in the soliton switching based on the Bloch-wave filtering in periodic photonic structures. Taking a binary waveguide array as an example, we demonstrate that spatial solitons that belong to different spectral band gaps can be selectively reflected from or transmitted through an engineered defect, which acts as a low or high-pass filter for Bloch waves.

ABSTRACT

This study aims to address decision-making and its implications, highlighting the importanceof organizational aspects. It explores decision-making procedures, examines the politicalfactors involved, and discusses procedural and organizational conflicts, presenting strategiesto minimize their negative effects. Given its risky nature, decision-making is extensivelystudied to ensure the success and continuity of an organization, since every decision made issubject to errors or successes that generate positive or negative consequences in the short orlong term. Therefore, this work seeks to provide a comprehensive set of guidelines andapproaches that can be effectively applied to assist in making quality decisions.
