description: Classifying irrigated fields into zones with different probabilities to reach a specific yield potential percentage (YP%) is imperative in the management of soil salinity and crop yield. Three nonlinear geostatistical models: Disjunctive Kriging (DK), Indicator Kriging (IK), and Probability Kriging (PK) are investigated in this study. Conditional probability (CP) maps generated by these models are used to classify two irrigated fields into zones with different probabilities to reach a specific YP% for a given crop. Soil salinity thresholds of alfalfa and corn were used as the conditions for applying the three models on the two datasets of two irrigated fields to generate CP maps for the two evaluated crops (alfalfa and corn). The objectives of this study are: 1) compare different CP maps generated using DK, IK, and PK; 2) compare the estimated YP% of alfalfa and corn under different soil salinity thresholds based on the CP maps generated by the three models; and 3) provide some guidance to growers to help them decide which crops to grow or whether some remediation actions need to be taken or not. The three models were applied on two datasets of soil salinity (316 and 163 data points) collected in two irrigated fields. These datasets were selected from a project conducted in the southeastern part of the Arkansas River Basin in Colorado where soil salinity impacts the crop productivity. Alfalfa and corn were selected because they are prevailing crops in the study area. Also, alfalfa represents a moderate tolerant crop while corn represents a moderate sensitive crop. The results of this study show that the DK, IK, and PK techniques give an accurate characterization and quantification of the different zones of the irrigated fields. The generated CP maps using DK are more accurate than those generated using IK and PK. The generated CP maps can be used to quantify and assess the productivity of different crops under different soil salinity thresholds.

description: Group recommender system is built to overcome the different needs that exist in each of the tour group members in determining tourist destinations. This is because everyone has different desires in determining the constraints of tourist destinations, such as costs and tourist categories. This recommendation process is based on a combination of profiles of each member to produce a tourist destination that can fulfill their needs. The method used is hybrid filtering which is a combination of collaborative filtering and knowledge-based filtering. Because the two methods have their own shortcomings. The collaborative method has a deficiency of tourist items that have never been rated by a user before, so the item cannot be recommended for active users. While in knowledge-based, tourist items must be completely described in detail so that they can be recommended to users. Domain used in this research is Bandung Raya area. The results of the evaluation in this study, users tend to feel very satisfied for the results of group travel recommendations generated the application by 50%. As for the evaluation of the recommendation algorithm, users prefer the results of the recommendations produced by collaborative and hybrid methods.

description: Pro-social punishment, whereby cooperators punish defectors, is often suggested as a mechanism that maintains cooperation in large human groups. Importantly, models that support this idea have to date only allowed defectors to be the target of punishment. However, recent empirical work has demonstrated the existence of anti-social punishment in public goods games. That is, individuals that defect have been found to also punish cooperators. Some recent theoretical studies have found that such anti-social punishment can prevent the evolution of pro-social punishment and cooperation. However, the evolution of anti-social punishment in group-structured populations has not been formally addressed. Previous work has informally argued that group-structure must favour pro-social punishment. Here we formally investigate how two demographic factors, group size and dispersal frequency, affect selection pressures on pro- and anti-social punishment. Contrary to the suggestions of previous work, we find that anti-social punishment can prevent the evolution of pro-social punishment and cooperation under a range of group structures. Given that anti-social punishment has now been found in all studied extant human cultures, the claims of previous models showing the co-evolution of pro-social punishment and cooperation in group-structured populations should be re-evaluated.

description: This paper looks at the evolution of ten public pension and sovereign wealth funds which have been on the cutting edge of innovation and best practice with respect to governance and investment management. The analysis is based on an inductive approach, proceeding from specific observations to general principles. In particular, we review ten case studies of individual funds from three regions – Northern Europe, Canada and Australasia. We look at three funds in Canada and one each in Australia, the Netherlands, Denmark, Norway, New Zealand, Singapore, and Sweden, using the same template for each entity.

We start with a brief description of the fund and explicate its liability profile, covering the source of funding and the intended use for the assets. We then review the fund’s current governance arrangements, with a particular emphasis on how these may have helped or hindered the fund’s investment professionals in their activity. We then look at the evolution of the fund’s investment strategy, focusing in particular on asset allocation and portfolio construction. We conclude each case by highlighting a feature unique to the fund in question, which we believe is worthy of further study and emulation by their less advanced peers.

At the end, we bring all of these separate strands together, with a view to formulating some general observations about how the best‐in‐breed public pension and sovereign wealth funds within our universe have evolved with respect to governance and investment strategy. Specifically, we try to determine whether the ten funds in question have been converging onto one model, or whether their experiences suggest increasing divergence. This section can effectively be viewed as a distillation of some preliminary recommendations for the less advanced funds, based on what we believe to be an emerging consensus around ‘best practice’ in public sector fund management.

description: Harmonic analysis is a tool to infer cosmic topology from the measured astrophysical cosmic microwave background CMB radiation. For overall positive curvature, Platonic spherical manifolds are candidates for this analysis. We combine the specific point symmetry of the Platonic manifolds with their deck transformations. This analysis in topology leads from manifolds to orbifolds. We discuss the deck transformations of the orbifolds and give eigenmodes for the harmonic analysis as linear combinations of Wigner polynomials on the 3-sphere. These provide new tools for detecting cosmic topology from the CMB radiation.

description: A scheme is developed for estimating state-dependent drift and diffusion coefficients in a stochastic differential equation from time-series data. The scheme does not require to specify parametric forms for the drift and diffusion coefficients in advance. In order to perform the nonparametric estimation, a maximum likelihood method is combined with a concept based on a kernel density estimation. In order to deal with discrete observation or sparsity of the time-series data, a local linearization method is employed, which enables a fast estimation.

description: Focused ultrasound with microbubbles has been used to noninvasively and selectively deliver pharmacological agents across the blood-brain barrier (BBB) for treating brain diseases. Acoustic cavitation monitoring could serve as an on-line tool to assess and control the treatment. While it demonstrated a strong correlation in small animals, its translation to primates remains in question due to the anatomically different and highly heterogeneous brain structures with gray and white matteras well as dense vasculature. In addition, the drug delivery efficiency and the BBB opening volume have never been shown to be predictable through cavitation monitoring in primates. This study aimed at determining how cavitation activity is correlated with the amount and concentration of gadolinium delivered through the BBB and its associated delivery efficiency as well as the BBB opening volume in non-human primates. Another important finding entails the effect of heterogeneous brain anatomy and vasculature of a primate brain, i.e., presence of large cerebral vessels, gray and white matter that will also affect the cavitation activity associated with variation of BBB opening in different tissue types, which is not typically observed in small animals. Both these new findings are critical in the primate brain and provide essential information for clinical applications.

description: We construct models of interacting itinerant non-Abelian anyons moving along one-dimensional chains, focusing in particular on itinerant Ising anyon chains, and derive effective anyonic t-J models for the low energy sectors. Solving these models by exact diagonalization, we find a fractionalization of the anyons into charge and (non-Abelian) anyonic degrees of freedom -- a generalization of spin-charge separation of electrons which occurs in Luttinger liquids. A detailed description of the excitation spectrum by combining spectra for charge and anyonic sectors requires a subtle coupling between charge and anyonic excitations at the microscopic level (which we also find to be present in Luttinger liquids), despite the macroscopic fractionalization.

description: We consider a finite mixture of regressions (FMR) model for high-dimensional inhomogeneous data where the number of covariates may be much larger than sample size. We propose an l1-penalized maximum likelihood estimator in an appropriate parameterization. This kind of estimation belongs to a class of problems where optimization and theory for non-convex functions is needed. This distinguishes itself very clearly from high-dimensional estimation with convex loss- or objective functions, as for example with the Lasso in linear or generalized linear models. Mixture models represent a prime and important example where non-convexity arises. For FMR models, we develop an efficient EM algorithm for numerical optimization with provable convergence properties. Our penalized estimator is numerically better posed (e.g., boundedness of the criterion function) than unpenalized maximum likelihood estimation, and it allows for effective statistical regularization including variable selection. We also present some asymptotic theory and oracle inequalities: due to non-convexity of the negative log-likelihood function, different mathematical arguments are needed than for problems with convex losses. Finally, we apply the new method to both simulated and real data.

description: We review applications of noncommutative geometry in canonical quantum gravity. First, we show that the framework of loop quantum gravity includes natural noncommutative structures which have, hitherto, not been explored. Next, we present the construction of a spectral triple over an algebra of holonomy loops. The spectral triple, which encodes the kinematics of quantum gravity, gives rise to a natural class of semiclassical states which entail emerging fermionic degrees of freedom. In the particular semiclassical approximation where all gravitational degrees of freedom are turned off, a free fermionic quantum field theory emerges. We end the paper with an extended outlook section.

description: A strontium iodide crystal doped by europium (SrI2(Eu)) was produced by using the Stockbarger growth technique. The crystal was subjected to a characterization that includes relative photoelectron output and energy resolution for gamma quanta. The intrinsic radioactivity of the SrI2(Eu) crystal scintillator was tested both by using it as scintillator at sea level and by ultra-low background HPGe gamma spectrometry deep underground. The response of the SrI2(Eu) detector to alpha particles (alpha/beta ratio and pulse shape) was estimated by analysing the 226Ra internal trace contamination of the crystal. We have measured: alpha/beta=0.55 at E_alpha=7.7 MeV, and no difference in the time decay of the scintillation pulses induced by alpha particles and gamma quanta. The application of the obtained results in the search for the double electron capture and electron capture with positron emission in 84Sr has been investigated at a level of sensitivity: T_1/2 \sim 10^{15}-10^{16} yr. The results of these studies demonstrate the potentiality of this material for a variety of scintillation applications, including low-level counting experiments.

Implementation of respiratory-correlated cone-beam CT on Varian linac systems
Creators: name: Cropp, Robert James
Publisher: name: University of British Columbia
Year: 2011

description: Respiratory-correlated (4D) X-ray CT scans produce a set of images corresponding to different phases of a patient's breathing cycle. In external beam radiotherapy, information about a tumor's motion due to respiration can be used to optimize a treatment plan, provided the patient can be accurately aligned for treatment. Cone-beam CT (CBCT) systems are becoming widespread on treatment linac units and are used to aid in alignment. This thesis describes the implementation of respiratory-correlated cone-beam CT scans on two types of Varian units: iX and TrueBeam. Procedures for 4D CBCT scans on each type have been developed and used to image a moving phantom. The respiratory phase of the motion is recorded with the Varian Real-time Position Management (RPM) system, which uses optical tracking. To improve image quality, the gantry rotation speed is reduced below the default value of 6°/s: this reduces streak artifacts. Each projection image from the scan is assigned to one of ten phase bins according to its respiratory phase value. A 3D image is reconstructed for each phase bin with software developed for this project, which uses conventional Feldkamp-Davis-Kress filtered backprojection. Four 4D scans of a periodically moving phantom have been taken, with different gantry speeds and mAs values. To evaluate the effect of these scan parameters on image quality, and demonstrate a potential application of 4D CBCT, a procedure for automated tumor trajectory measurement has been developed. The measurement uses image registration between phase images, with either a rigid translation or a B-spline deformation algorithm. In the highest-quality images, the displacements of an insert in the phantom are measured within 1 mm of the correct values by both algorithms. In lower-quality images the translation algorithm is more robust. The two algorithms give similar results when applied to 4D CT images of actual lung cancer patients.

description: Interactions of domain walls (DWs) are analyzed with relevance to formation of stationary bubbles (complexes of two DWs) and complexes of many domains in one dimensional systems. I investigate the domain structures in ferromagnets which are described with the Landau-Lifshitz equation as well as the domains in critical systems described with the Ginzburg-Landau equation. Supplementing previous author studies on the creation of hard bubbles [formed by one Bloch DW and one Neel (Ising) DW] in the presence of an external (magnetic) field, the soft bubbles consisting of two Bloch DWs or two Neel (Ising) DWs are studied in detail. The interactions of two DWs of the same kind are studied in the framework of a perturbation calculus.

description: Adolescent idiopathic scoliosis is a complex disease with unclear etiopathogenesis. Systemic and persistent low bone mineral density is an independent prognostic factor for curve progression. The fundamental question of how bone quality is affected in AIS remains controversy because there is lack of site-matched control for detailed analysis on bone-related parameters. In this case-control study, trabecular bone biopsies from iliac crest were collected intra-operatively from 28 severe AIS patients and 10 matched controls with similar skeletal and sexual maturity, anthropometry and femoral neck BMD Z-score to control confounding effects. In addition to static histomorphometry, micro-computed tomography (μCT) and real time-PCR (qPCR) analyses, individual trabecula segmentation (ITS)-based analysis, finite element analysis (FEA), energy dispersive X-ray spectroscopy (EDX) were conducted to provide advanced analysis of structural, mechanical and mineralization features. μCT and histomorphometry showed consistently reduced trabecular number and connectivity. ITS revealed predominant change in trabecular rods, and EDX confirmed less mineralization. The structural and mineralization abnormality led to slight reduction in apparent modulus, which could be attributed to differential down-regulation of Runx2, and up-regulation of Spp1 and TRAP. In conclusion, this is the first comprehensive study providing direct evidence of undefined unique pathological changes at different bone hierarchical levels in AIS.

description: A new method has been developed to estimate the parameters of a water balance model's components (actual evapotranspiration, drainage plus runoff) as functions of the soil moisture and of the estimated parameters. The technique requires limited information, that is measured precipitation and soil moisture plus potential evapotranspiration; in particular, the method needs only an index of the soil moisture content, becoming easy to be applied to remotely sensed measures of soil moisture. The method's skills are evaluated using long series of synthetic data, both at point and hillslope scales, and series of data measured for shorter periods.

description: Despite conceptual links between disaster exposure and substance use, few studies have examined prevalence and risk factors for adolescent substance use and abuse in large, population-based samples affected by a recent natural disaster. We addressed this gap using a novel address-based sampling methodology to interview adolescents and parents who were affected by the 4th deadliest tornado outbreak in U.S. history. Postdisaster interviews were conducted with 2,000 adolescent–parent dyads living within a 5-mile radius of the spring 2011 U.S. tornadoes. In addition to descriptive analyses to estimate prevalence, hierarchical linear and logistic regression analyses were used to examine a range of protective and risk factors for substance use and abuse. Approximately 3% reported substance abuse since the tornado. Greater number of prior traumatic events and older age emerged as consistent risk factors across tobacco and alcohol use and substance abuse since the tornado. Tornado incident characteristics, namely, greater loss of services and resources after the tornado and posttraumatic stress disorder since the tornado, were associated with greater alcohol consumption. Service loss increased risk for binge drinking, whereas, for substance abuse, posttraumatic stress disorder increased risk and parent presence during the tornado decreased risk. Greater family tornado exposure was associated with a greater number of cigarettes smoked in female but not male teen participants. Both trauma and non-trauma-related factors are relevant to postdisaster substance abuse among adolescents. Future research should examine the role of broader ecological systems in heightening or curtailing substance use risk for adolescents following disaster exposure.

description: The economic history of municipal finance in Ontario has been neglected. This dissertation consists of three essays that together address the development of the municipal fisc and assess the impact of the Great Depression on municipal finance in Ontario and the fiscal response of municipalities to the crisis. The crisis was a "defining moment" fiscally for municipalities in Ontario and in intergovernmental fiscal relations between the Province and municipalities. The first essay describes the development of the Ontario municipal fiscal system as a whole to 1941. The second essay focuses on the process of transition from a relatively soft budget constraint facing municipalities prior to the Great Depression to a relatively hard hierarchical constraint imposed by the Province as a crisis response. Hard hierarchical constraints have subsequently been reinforced by market forces and continue to persist. The third essay assesses the evidence that municipal spending and taxing decisions were adversely affected by pressure to finance education and both mandatory and discretionary municipal services in the context of a shared and weakened property tax base. Together, the three show the development of municipal fiscal capacity to meet the demands of an increasingly urbanized population and assess the "squeeze" on this capacity that arose from the general economic conditions of the Great Depression, affecting a narrow tax base combined with the mandatory financing of public education and poor relief. The essays also show that a lasting legacy of institutional development was also created.

description: The properties of two-flavored massive Nambu--Jona-Lasinio model in (1+1)-dimensional spacetime are investigated in the presence of isospin and quark number chemical potentials. The consideration is performed in the large-$N_c$ limit, where $N_c$ is the number of colored quarks. It is shown in the framework of this model that charged pion condensation phenomenon of dense quark/hadron isotopically asymmetric matter is rather a spatially inhomogeneous than a homogeneous one.
