description: Recently, Ferreira da Silva et al. [3] have performed a gradient pattern analysis of a canonical sample set (CSS) of scanning force microscopy (SFM) images of p-Si. They applied the so-called Gradient Pattern Analysis to images of three typical p-Si samples distinguished by different absorption energy levels and aspect ratios. Taking into account the measures of spatial asymmetric fluctuations they interpreted the global porosity not only in terms of the amount of roughness, but rather in terms of the structural complexity (e.g., walls and fine structures as slots). This analysis has been adapted in order to operate in a OpenGL flyby environment (the StrFB code), whose application give the numerical characterization of the structure during the flyby real time. Using this analysis we compare the levels of asymmetric fragmentation of active porosity related to different materials as p-Si and "porous diamond-like" carbon. In summary we have shown that the gradient pattern analysis technique in a flyby environment is a reliable sensitive method to investigate, qualitatively and quantitatively, the complex morphology of active nanostructures.

description: The electronic band structures of two-dimensional materials are significantly different from those of their bulk counterparts, due to quantum confinement and strong modifications of electronic screening. An accurate determination of electronic states is a prerequisite to design electronic or optoelectronic applications of two-dimensional materials, however, most of the theoretical methods we have available to compute band gaps are either inaccurate, computationally expensive, or only applicable to bulk systems. Here we show that reliable band structures of nanostructured systems can now be efficiently calculated using density-functional theory with the local modified Becke-Johnson exchange-correlation functional that we recently proposed. After re-optimizing the parameters of this functional specifically for two-dimensional materials, we show, for a test set of almost 300 systems, that the obtained band gaps are of comparable quality as those obtained using the best hybrid functionals, but at a very reduced computational cost. These results open the way for accurate high-throughput studies of band-structures of two-dimensional materials and for the study of van der Waals heterostructures with large unit cells.
The Problems of Analysing Markets for Irrigation Water

Subjects: Resource /Energy Economics and Policy

description: The view that the price of water is too low and that water does not flow to its highest value end use, have led many analysts to conclude that a market for water, in which price can adjust to accommodate changes in the supply and demand for the product, is essential. However, this solution assumes that the market could approach something close to perfect competition, purely by making minor changes within the existing regime of property rights. In this paper it is argued that problems evident in this market stem from a multitude of market failures and characteristics that are particular to it. To understand this case more fully it is necessary to come to terms with the theoretical formulations of the market for water and the practical difficulties associated with it. It is concluded that it may not be possible to obtain an optimal solution in the market for water, as it currently exists. Thus, the solutions to the problems evident in the water market may need to rely on controlling quantity of water that flows through it, even though price is an ideal economiser of information.
The rapidly oscillating Ap star HR 1217 : the effect of a magnetic field on pulsation
Creators: name: Cameron, Christopher J.
Publisher: name: University of British Columbia
Year: 2009

description: The rapidly oscillating Ap (roAp) stars provide a unique opportunity to observe and test processes that until recently could only be studied in detail for the Sun. As a class, these stars possess extreme examples of chemical inhomogeneities through the effects of gravitational settling, mixing and radiative accelerations; magnetic fields that affect both the micro- and macroscopic physics that influence stellar structure; and high overtone pulsations. For the latter, we may use the tools developed for asteroseismic analysis: the inference of the internal structural properties of a star based on information from its pulsational instabilities. One of the most studied of the roAp stars is HR 1217. The rapid variability of this star was first discovered by Kurtz (1982). Later, Kurtz et al. (1989) extended photometric observations of HR 1217 during a global campaign. They discovered six primary frequencies with periods near 6 minutes and a spacing pattern that is reminiscent of pulsations observed in the Sun. This thesis presents a revised frequency analysis of photometric data on HR 1217 obtained during a Whole Earth Telescope (WET) campaign in late 2000. In particular, we identify a new frequency at 2788.94 μHz with a characteristic second-order p-mode spacing of 2.63 μHz from another frequency previously reported by Kurtz et al. (2002). Evolutionary and pulsational models of A stars are also presented with a discussion of how a magnetic field can perturb the acoustic frequencies. To accomplish this, the variational method used by Cunha & Gough (2000) is adapted to calculate magnetic perturbations to the acoustic modes calculated from our evolutionary models. These perturbations are used to explain the unexpected frequency spacing observed in HR 1217.

description: Agriculture contributes significantly to the emissions of greenhouse gases in the EU. By using a farm-type, linear-programming based model of the European agricultural supply, we first assess the initial levels of methane and nitrous oxide emissions at the regional level in the EU. For a range of CO2 prices, we assess the potential abatement that can be achieved through an IPCC-based emission tax in EU agriculture, as well as the resulting optimal mix of emission sources in the total abatement. Further, we show that the spatial variability of the abatement actually achieved at a given carbon price is large, indicating that abatement cost heterogeneity is a fundamental feature in the design of a mitigation policy. We assess the efficiency loss associated with uniform standards relative to an emission tax.

description: Swift has two main types of ``rate'' triggers: short and long. Short trigger time scales range from 4ms to 64ms, while long triggers are 64ms to ~ 16 seconds. While both short and long trigger have criteria with one background sample (traditional ``one-sided'' triggers), the long triggers can also have criteria with two background samples (``bracketed'' triggers) which remove trends in the background. Both long and short triggers can select energy ranges of 15-25, 15-50, 25-100 and 50-350 KeV. There are more than 180 short triggering criteria and approximately 500 long triggering criteria used to detect gamma ray bursts. To fully utilize these criteria, the thresholds must be set correctly. The optimum thresholds are determined by a tradeoff between avoiding false triggers and capturing as many bursts as possible. We use realistic simulated orbital variations, which are the prime cause of false triggers.

description: The results of a three-year study of the implications of China's accession to the WTO for its agricultural sector and policy options to maximise the benefits of the trade reforms are reported. The most important message from the study is that macro-economic and other non-agriculture specific policies can do much to improve the outcome for rural households and thereby improve food security. These policies include the promotion of urban development in inland areas and gradual reform of monetary policy. However, agricultural policies need further reform, including abandoning of price support and regional self-sufficiency policies, reform of monopolistic agricultural marketing and distribution activities, and reform of the state grain storage system. Hopefully, WTO membership will assist implementation of these reforms.
Modulation and enhancement of partial internal reflection at an opitical interface
Creators: name: Liptak, Anne Helene
Publisher: name: University of British Columbia
Year: 2009

description: This thesis investigates the mechanisms involved in a reflective display based on the control of partial internal reflection hereafter abbreviated PIR. This work was motivated by the development of a reflective display based on the frustration of total internal reflection.1 Total internal reflection can be prevented by placing an absorbing medium in the evanescent wave region. The reflection is restored when the absorber is pulled out of this region. Heavily coloured pigments suspended in a perfluorinated hydrocarbon serve as absorbers; their motion in and out of the evanescent zone is accomplished using electrophoresis. When light does not undergo total internal reflection, it is not obvious that this method of changing the reflectivity would be effective. Surprisingly, a similar change in reflectance can be observed as the absorbing pigments are brought into and out of the region a few nanometres from the interface. The thesis studies of such changes in partial reflection. The reflectance changes at a single optical interface caused by the motion of pigments were studied for light undergoing total and partial reflections. The mechanism controlling reflectance for partially reflected light is optical interference. The interference system was modeled to emulate experimental conditions with results agreeing well with experiment. The reflectance from a system with multiple reflections was controlled using the pigment suspension. Light undergoes partial reflection on several surfaces, and the compound losses due to transmission significantly reduce the overall reflectance. To increase the overall reflectance, a layer of aluminium was deposited on selected interfaces. To demonstrate the potential use of the modulation of PIR, flashing retroreflective panels were constructed, with the possible application of highway signs in mind. Reasonably encouraging reflectance values and contrast ratios were observed. It is suggested that further development of this technology is warranted, with the goal of creating electronically addressed variable message signs.

description: Issues concerning the long-term environmental and health risks associated with the production of genetically modified foods remain highly topical in Australia. It is unclear how consumers values for a precautionary approach to the release of genetically modified crops compares to the opportunity costs of forgoing economic growth associated with the use of these technologies. In this paper, an application of the contingent valuation method is reported. That technique was used to estimate quasi-option values held by consumers regarding a potential five year moratorium on the use of genetic modification in Australian agriculture. The results are compared to the estimated opportunity costs of imposing such a ban o Queensland consumers.

description: Quantum catalysis is a fascinating concept which demonstrates that certain transformations can only become possible when given access to a specific resource that has to be returned unaffected. It was first discovered in the context of entanglement theory and since then applied in a number of resource-theoretic frameworks, including quantum thermodynamics. Although in that case the necessary (and sometimes also sufficient) conditions on the existence of a catalyst are known, almost nothing is known about the precise form of the catalyst state required by the transformation. In particular, it is not clear whether it has to have some special properties or be finely tuned to the desired transformation. In this work we describe a surprising property of multi-copy states: we show that in resource theories governed by majorization all resourceful states are catalysts for all allowed transformations. In quantum thermodynamics this means that the so-called "second laws of thermodynamics" do not require a fine-tuned catalyst but rather any state, given sufficiently many copies, can serve as a useful catalyst. These analytic results are accompanied by several numerical investigations that indicate that neither a multi-copy form nor a very large dimension catalyst are required to activate most allowed transformations catalytically.

description: The article investigates the validity of Gibrat’s Law for French, Hungarian and Slovenian farms with FADN data and Heckman selection models, quantiles regressions and panel unit root tests. The contribution to the literature is threefold. First, we compare farm growth in countries with rather different farm structures. Second, we apply two different testing techniques. Finally, we focus on specialised crop and dairy farms rather than all farms, avoiding biases due to heterogeneous structures across the agricultural sector. Results reject the Gibrat’s Law for crop farms in France (except for one sub-period) and Hungary but confirm it for French and Slovenian dairy farms.

description: The thick- or fat-center-vortices model has been applied to a calculation of the potentials between static sources of various SU(4) representations. For intermediate distances, a linear potential is obtained. For this region the string tensions agree qualitatively with both flux tube counting and Casimir scaling, even though for some representations it favors flux tube counting more. In addition, our results confirm the existence of two different string tensions for non-zero 4-ality representations at large distances. In this area, zero 4-ality representations are screened. In our computations, we have used only the first non-trivial vortex of SU(4).

We propose that the interchain antiferromagnetic coupling in KCr3As3 plays a crucial role for the experimentally observed spin-glass phase with low critical temperature. In the same region of the parameter space, we predict K2Cr3As3 to be non-magnetic but on the verge of the magnetism, sustaining interchain ferromagnetic spin fluctuations while the intrachain spin fluctuations are antiferromagnetic.

description: Dark matter direct and indirect detection signals depend crucially on the dark matter distribution. While the formation of large scale structure is independent of the nature of the cold dark matter (CDM), the fate of inhomogeneities on sub-galactic scales, and hence the present day CDM distribution on these scales, depends on the micro-physics of the CDM particles. We study the density contrast of Weakly Interacting Massive Particles (WIMPs) on sub-galactic scales. We calculate the damping of the primordial power spectrum due to collisional damping and free-streaming of WIMPy CDM and show that free-streaming leads to a CDM power spectrum with a sharp cut-off at about $10^{-6} M_\odot$. We also calculate the transfer function for the growth of the inhomogeneities in the linear regime, taking into account the suppression in the growth of the CDM density contrast after matter-radiation equality due to baryons and show that our analytic results are in good agreement with numerical calculations. Combining the transfer function with the damping of the primordial fluctuations we produce a WMAP normalized primordial CDM power spectrum, which can serve as an input for high resolution CDM simulations. We find that the smallest inhomogeneities typically have co-moving radius of about 1 pc and enter the non-linear regime at a redshift of $60 \pm 20$. We study the effect of scale dependence of the primordial power spectrum on these numbers and also use the spherical collapse model to make simple estimates of the properties of the first generation of WIMP halos to form. We find that the very first WIMPy halos may have a significant impact on indirect dark matter searches.

description: We argue that frequent sampling of the fraction of infected people (either by random testing or by analysis of sewage water), is central to managing the COVID-19 pandemic because it both measures in real time the key variable controlled by restrictive measures, and anticipates the load on the healthcare system due to progression of the disease. Knowledge of random testing outcomes will (i) significantly improve the predictability of the pandemic, (ii) allow informed and optimized decisions on how to modify restrictive measures, with much shorter delay times than the present ones, and (iii) enable the real-time assessment of the efficiency of new means to reduce transmission rates. Here we suggest, irrespective of the size of a suitably homogeneous population, a conservative estimate of 15000 for the number of randomly tested people per day which will suffice to obtain reliable data about the current fraction of infections and its evolution in time, thus enabling close to real-time assessment of the quantitative effect of restrictive measures. Still higher testing capacity permits detection of geographical differences in spreading rates. Furthermore and most importantly, with daily sampling in place, a reboot could be attempted while the fraction of infected people is still an order of magnitude higher than the level required for a relaxation of restrictions with testing focused on symptomatic individuals. This is demonstrated by considering a feedback and control model of mitigation where the feed-back is derived from noisy sampling data.

description: Questions on farm structures (such as superiority of large farms) are typically linked to economies of scale. Economies of scale are normally a matter of investments in energy consuming technologies (large machinery). In contrast there is the issue of remaining prevalence of labour intensive, small farms (meant to be inferior); but which are less energy intensive. We see a revival in theoretical and policy debates on pathways of agricultural development concerning energy use. We analyse, how one can develop an approach that includes incentives to save energy and produce less GHG, and develop a framework of coexistence of farm types.

In addition, we prove that the familiar black hole thermodynamical expressions and in particular the first law continues to holds in general in the presence of arbitrary matter couplings to gravity.

We prove that $W$ is biautomatic. We do it by showing that a natural geodesic language is regular (for arbitrary $W$), and satisfies the fellow traveller property. As a consequence, by the work of Jacek Świątkowski, groups acting properly and cocompactly on buildings of type $W$ are also biautomatic. We also show that the fellow traveller property for the natural language fails for $W=\widetilde{A}_3$.

description: High performance Integrated Circuits (ICs) are a fundamental part of future Quantum Computers (QCs). The ICs of QCs need regulated, stable and noise free supply voltages. Supply voltage lines in dilution fridges are prone to voltage ripple noise due to pulse tube vibrations, ground loops induce noise and dynamic load currents. Cryogenic ICs for in situ voltage regulation can provide a clean voltage supply for the ICs of QCs. A voltage reference and a voltage regulator are presented as building blocks for cryogenic voltage regulation. The investigated circuits were developed in 22 nm FDSOI technology and tested from 6 K to 300 K.

We show that the scale invariance implies that the Hagedorn behaviour of bosonic and supersymmetric strings in these backgrounds, even with the inclusion of RR or NS fields, is the same as that of strings in flat space. This is in marked contrast to the behaviour of strings in the BFHP plane wave which exhibit quantitatively and qualitatively different thermodynamic properties.

description: The topology of insulators is usually revealed through the presence of gapless boundary modes: this is the so-called bulk-boundary correspondence. However, the many-body wavefunction of a crystalline insulator is endowed with additional topological properties that do not yield surface spectral features, but manifest themselves as (fractional) quantized electronic charges localized at the crystal boundaries. Here, we formulate such bulk-corner correspondence for the physical relevant case of materials with time-reversal symmetry and spin-orbit coupling. To so do we develop "partial" real-space invariants that can be neither expressed in terms of Berry phases nor using symmetry-based indicators. These new crystalline invariants govern the (fractional) quantized corner charges both of isolated material structures and of heterostructures without gapless interface modes. We also show that the partial real-space invariants are able to detect all time-reversal symmetric topological phases of the recently discovered fragile type.

description: This paper conducts a detailed, micro-focused investigation on the implications of recent agricultural policy changes on the structure of production systems in Ireland, Denmark and the Netherlands in terms of farm numbers, system switching, specialisation, the role of economies of scale, on-farm investment, off-farm employment and economic viability. Given the close relationship between farm structure and agricultural production, the impact of the recent CAP reform on production decisions should give a good indication of the form agricultural structural change will take. Two competing hypotheses of post decoupling structural change are proposed; a ‘production inducing effect’ and an ‘expectations effect’. Using Irish, Danish and Dutch micro-data, which are comparable due to their participation in FADN, a descriptive analysis of the key characteristics of production in the agri-food sectors in each country will be performed using key indicators of structural change. The results indicate that the ‘expectations effect’, which claims that producers may adopt a ‘safety first’ strategy and make only minimal changes to production plans in case future payments are reassessed and re-linked to production or an agricultural activity, seems to be prevalent.

description: Variable-density mixing in shock bubble interaction, a canonical flow of Richtermyer-Meshkov instability, is studied by the high-resolution simulation. While the dissipation mainly controls the passive scalar mixing rate, an objective definition of variable-density mixing rate characterizing the macroscopic mixing formation is still lacking, and the fundamental behavior of mixing rate evolution is not yet well understood. Here, we first show that the variable-density mixing of shock bubble interaction is distinctly different from the previous observations in the passive scalar mixing. The widely-accepted hyperbolic conservation of the first moment of concentration in the scalar mixing, i.e., the conservation of the mean concentration, is violated in variable-density flows. We further combine the compositional transport equation and the divergence relation for the miscible flows to provide the evidence that the existence of density gradient accelerated mixing rate, decomposed by the accelerated dissipation term and redistributed diffusion term, contributes to the anomalous decrease or increase of the mean concentration depending on Atwood number. Further analyzing a number of simulations for the cylindrical or spherical bubbles under a broad range of shock Mach numbers, Reynolds numbers, and Peclet numbers, the density gradient accelerated mixing rate exhibits weak dependent on Peclet numbers, and identifies an Atwood number range with high mixing rate, which can be theoretically predicted based on the mode of hyperbolic conservation violation behavior.

description: With the increasing commodity prices volatility over the last years and the successive agricultural policy reforms, European grain producers face greater uncertainty. To better understand consequences of a price risk increase on production decisions, marketing decisions and farm revenue as well as linkage between production and marketing decisions, we develop a multiperiodic risk farm model. Production decisions concern selections of crop mix and farming practices (conventional or integrated farming) while marketing decisions focus on four types of pricing arrangements. The model is applied to a representative farmer of a region located in the Southwest of France. The results exposed in this paper shows that with a price risk increase, production adjustments of a risk averse farmer are oriented toward less risky (environmentally friendly) farming practices unless marketing contracts allow to mitigate price risk.

description: Empirical evidence shows that non-farm income diversification is associated with higher welfare among farm households. However, most studies have ignored market barriers and farm income risk in explaining income diversification behaviour. This study develops an analytical framework that includes both market barriers and farm income risk, in addition to other factors, in explaining income diversification behaviour. The analytical framework is used to test the hypotheses that: market barriers reduce the intensity of non-farm income diversification; and farm income risk increases the intensity of non-farm income diversification. The results confirm the hypotheses, suggesting that market barriers and farm income risk are key factors in explaining income diversification behaviour of farm households. Future studies should, therefore, consider the two factors in the analysis of income diversification behaviour.

description: This study examines consumers' WTP for reductions in greenhouse gas emissions from E85 as opposed to gasoline. Data were collected via a contingent choice exercise in a 2009 national online survey. As part of the fuel choice exercise, several fuel attributes were allowed to vary including emission reductions, import level, proximity of fuel availability, price, and fuel blend (E85 or regular gasoline). A random parameters model with demographics and attitudes interacted with emission reductions was estimated. The resulting estimates suggest that, overall the WTP for an emission reduction is not statistically significant. However, for some demographic and attitudinal profiles, the WTP is significant. An example profile includes younger age, female, concerned about climate change, not supportive of additional drilling, supportive of farmland being used for fuel, own or are likely to own a FlexFuel vehicle, and primary vehicle not an SUV.

description: A mechanistic understanding of mineral precipitation induced clogging and its non-linear feedback on macroscopic transport properties of porous media is essential for predicting the long-term evolution of nuclear waste repositories. Most disposal concepts rely on a multibarrier system, combining engineered and geological barriers to provide a safe containment of the radioactive waste. At the interfaces between different barriers, chemical and thermal gradients promote mineral precipitation reactions, resulting in a reduction of porosity and potentially localized clogging. Clogging of transport pathways may appear desirable to inhibit radionuclide migration, but can also be detrimental, particularly in the case of a hindered removal gases generated, for example, due to anoxic corrosion of metallic waste canisters or degradation of organic waste components. Commonly applied porosity-diffusivity relations in continuum-scale reactive transport modelling based on Archie’s law and extended versions thereof predict the case of clogging as a final state. However, recent experiments and pore scale modelling investigations suggest that dissolution – recrystallization processes cause a non-negligible inherent diffusivity of newly formed precipitates. To verify this hypothesis, we present a microfluidic reactor design that combines time-lapse optical microscopy and confocal Raman spectroscopy, providing real-time insights into mineral precipitation induced porosity clogging under purely diffusive transport conditions, using the precipitation of celestine (SrSO4) as a model system. Based on 2D optical images of the reaction progress, the effective diffusivity of the evolving porous medium was determined as a function of time using pore scale modelling. At the clogged state, isotopic tracer experiments were conducted and monitored by in situ Raman spectroscopy to visualize the transport of deuterium through the evolving microporosity of the precipitates, demonstrating the non-final state of clogging. The evolution of the porosity – diffusivity relation in response to precipitation reactions shows a contradictory behavior to Archie’s law. The application of an extended power law improved the description of the evolving porosity – diffusivity relation, but still neglected post-clogging features. Currently, we continue to develop a microfluidic setup to answer the question how clogging-related processes depend on initial pore geometries. The innovative combination of microfluidic experiments and pore-scale modelling opens new possibilities to validate and identify relevant pore-scale processes, providing data for upscaling approaches to derive key relationships for continuum-scale reactive transport simulations.
