description: The electron hole concentration p in the CuO2 planes of YBa2Cu3O6+x (YBCO) has been evaluated using the unit cell length in the c-direction together with a simple estimation for p in the chain oxygen ordered phases. The empirical relationship between p and c obtained allows calculation of p from the c-axis lattice parameter for the entire doping range of YBCO. It is also suggested that the empirical parabola describing the relationship between Tc and p in La2-dSrdCuO4 is reasonably correct for YBCO except for the region around p =1/8, where the Tc of YBCO is suppressed by as much as 17 K. A correction of the parabola for the p = 1/8 effect is presented.

description: We present the multiloop partition function of open bosonic string theory in the presence of a constant gauge field strength, and discuss its low-energy limit. The result is written in terms of twisted determinants and differentials on higher-genus Riemann surfaces, for which we provide an explicit representation in the Schottky parametrization. In the field theory limit, we recover from the string formula the two-loop Euler-Heisenberg effective action for adjoint scalars minimally coupled to the background gauge field.

description: We study the spectrum of anomalous dimensions of operators dual to giant graviton branes. The operators considered belong to the su$(2|3)$ sector of ${\cal N}=4$ super Yang-Mills theory, have a bare dimension $\sim N$ and are a linear combination of restricted Schur polynomials with $p\sim O(1)$ long rows or columns. In the same way that the operator mixing problem in the planar limit can be mapped to an integrable spin chain, we find that our problem maps to particles hopping on a lattice. The detailed form of the model is in precise agreement with the expected world volume dynamics of $p$ giant graviton branes, which is a U$(p)$ Yang-Mills theory. The lattice model we find has a number of noteworthy features. It is a lattice model with all-to-all sites interactions and quenched disorder.

description: The ratio of the low-energy absorption cross section for Dirac fermion to that for minimally coupled scalar is computed when the spacetimes are various types of the higher-dimensional Reissner-Nordström black holes. It is found that the low-energy absorption cross sections for the Dirac fermion always goes to zero in the extremal limit regardless of the detailed geometry of the spacetime. The physical importance of our results is discussed in the context of the brane-world scenarios and string theories.

description: Relativistic neutron-loaded outflows in gamma-ray bursts are studied at their early stages, before deceleration by a surrounding medium. The outflow has four components: radiation, electrons, protons and neutrons. The components interact with each other and exchange energy as the outflow expands. The presence of neutrons significantly changes the outflow evolution. Before neutrons decouple from protons, friction between the two components increases their temperatures by many orders of magnitude. After the decoupling, the gradual neutron decay inside the outflow has a drag effect on the protons and reduces their final Lorentz factor.

description: Einstein's explanation of Brownian motion provided one of the cornerstones which underlie the modern approaches to stochastic processes. His approach is based on a random walk picture and is valid for Markovian processes lacking long-term memory. The coarse-grained behavior of such processes is described by the diffusion equation. However, many natural processes do not possess the Markovian property and exhibit to anomalous diffusion. We consider here the case of subdiffusive processes, which are semi-Markovian and correspond to continuous-time random walks in which the waiting time for a step is given by a probability distribution with a diverging mean value. Such a process can be considered as a process subordinated to normal diffusion under operational time which depends on this pathological waiting-time distribution. We derive two different but equivalent forms of kinetic equations, which reduce to know fractional diffusion or Fokker-Planck equations for waiting-time distributions following a power-law. For waiting time distributions which are not pure power laws one or the other form of the kinetic equation is advantageous, depending on whether the process slows down or accelerates in the course of time.
title: Exploring the effects of management strategies on the gut microbiome and metabolome of growing broiler chickens: an integrated metagenomic and metabolomic approach
Creators: name: Tonks, Alexandra A.
Publisher: name: University of Reading
Year: 2019

description: Advances in genetic selection and intensification of management systems has led to the production of highly efficient broiler chickens. Attention is being turned to the role of gut microbes to further growth efficiency and improve animal health, particularly with the rise of antimicrobial resistance and the need to consider animal welfare and food safety. The microbiome is sensitive to management strategies, which may affect the growth and metabolism of the bird. Here, four studies are presented which explore the effects of antibiotic treatment with Linco-spectin and the subsequent use of Aviguard®, a mixed probiotic, diet in terms of protein source and the use of wheat or maize as a cereal base, and the supplementation of bedding with excreta from mature birds on the caecal microbiome and hepatic metabolome of broilers through population profiling metabolomic approaches. A final analysis of all datasets highlights consistent trends that appeared irrespective of treatment. Alpha diversity increased between days 4 and 9 (P<0.001) and 15 and 22 (P=0.001) and was affected by all treatments but differences dissipated with age. Beta diversity also changed with age, but again differences were reduced by around two weeks of age, suggesting that diversity naturally reaches a plateau, irrespective of perturbations in early life. Age-related shifts in bacterial populations were observed in all studies with a reciprocal relationship between phyla Firmicutes and Tenericutes (P<0.001). The microbiome was consistently affected by management strategy, with evidence that different taxa are affected by diet, bedding and antibiotic/probiotic treatment. Energyrelated metabolites were affected by treatment, but birds appeared to grow equally as well suggesting isofunctionality of the hepatic metabolome. Concentrations of short chain fatty acids (SCFA) increased between days 4 and 15 (P<0.001) and were affected by diet alone. Concentrations of all SCFA exhibited both positive and negative relationships with bacterial taxa. Despite the plethora of treatment-associated differences in the microbiome, no single group of birds performed worse than another with a lack of a significant relationships between differences in the caecal bacterial populations and differences in feed conversion ratio (r=0.386; P=0.270). It is hypothesised that the ability of a bird to thrive and grow is independent of the profile of its microbiome, so long as key metabolic activities are performed. This thesis is an overview that will provide a base to be utilised in exploring more specific relationships in depth in future work with methods and understanding of metagenomic-metabolomic relationships improved by the findings herein.

description: Distribution transformers are an essential component employed widely in electrical power transmission systems. Heat generation in summer due to overloading on these transformers, is a critical problem especially in developing countries like Pakistan. These transformers are designed to operate within specific temperature range. The significant factors involved in temperature rise are; quantity of oil, geometric parameters of tank and fins as well as heat transfer coefficients of their materials and coatings. Improper heat dissipation causes frequent tripping, degrades the insulation quality and decreases the transformer’s life. Therefore, efficient cooling is an essential requirement for its durable operation. The main objective, of this project, is to enhance the heat transfer rate of domestic transformers by optimizing the fin design using numerical analysis and CFD analysis approach, to improve its overall performance and life expectancy. A comparison of results is performed between conventional and optimized designs in terms of optimum number of fins required for specific overloading conditions. The proposed fin design of transformer for improved cooling process would be helpful, in decreasing annual expenditures being spent by the government on frequent malfunctioning of transformers. It is worth noting that environmental effects also influence the cooling process externally. Further optimization of thermal conductivity and dielectric strength of mineral oil is done by mixing "Alumina" nanoparticles in it. The stability of nanofluids is the major concern for their use at commercial level instead of oil although they have better thermal properties.

description: ICARUS T600 is the far detector of the Short Baseline Neutrino program at Fermilab(USA), which foresees three Liquid Argon Time Projection Chambers along the Booster Neutrino Beam line to search for LSND-like sterile neutrino signal. The T600 detector underwent a significant overhauling process at CERN, introducing new technological developments while maintaining the already achieved performances. The realization of a new liquid argon scintillation light detection system is a primary task of the detector overhaul. As the detector will be subject to a huge flux of cosmic rays, the light detection system should allow the 3D reconstruction of events contributing to the identification of neutrino interactions in the beam spill gate. The design and implementationof the new scintillation light detection system of ICARUS T600 is described.

description: Ethiopia experiences a fierce political debate about the appropriate land tenure policy. After the fall of the socialist derg regime in 1991, land property rights have remained vested in the state and only usufruct rights have been alienated to farmers – to the disappointment of international donor agencies. This has nurtured an antagonistic debate between advocates of the privatization of land property rights to individual plot holders and those supporting the government’s position. This debate, however, fails to account for the diversity and continuities in Ethiopian land tenure systems. This paper reviews the changing bundles of rights farmers have held during various political regimes in Ethiopia, the imperial, the derg and the current one, at different times and places. Our analysis indicates the marked differences in tenure arrangements after the fall of the empire, but identifies some commonalities in land tenure regimes as well, in particular between the traditional rist system and the current tenure system.
High-level specification and automatic generation of IP interface monitors

Publisher: name: University of British Columbia
Year: 2009

description: A central problem in functional verification is to check that a circuit block is producing correct outputs while enforcing that the environment is providing legal inputs. To attack this problem, several researchers have proposed monitor-based methodologies, which offer many benefits. This thesis presents a novel, high-level specification style for these monitors, along with a linear-size, linear-time translation algorithm into monitor circuits. The specification style naturally fits the complex, but well-specified interfaces used between IP blocks in systems-on-chip. To demonstrate the advantage of our specification style, we have specified monitors for various versions of the Sonics OCP protocol as well as the AMBA AHB protocol, and have developed a prototype tool that automatically translates specifications into Verilog or VHDL monitor circuits.

description: From 2000 through 2004, per capita orange juice purchases decreased by 12.3 percent while the popularity and media coverage of low-carbohydrate dieting exploded. Content analysis was used to count selected Southern region newspaper articles topically related to low-carbohydrate dieting, the Atkins diet, and the South Beach diet. This data was included in a Southern region orange juice demand model, where purchase data served as the independent variable and proxy for consumer demand of orange juice. Results indicated that media coverage of low-carbohydrate diets and dieting was negatively and significantly related to demand for orange juice in the Southern region.

description: Using the optical Stern-Gerlach model, we have recently shown that the non-local correlations between the internal variables of two atoms that successively interact with the field of an ideal cavity in proximity of a nodal region are affected by the atomic translational dynamics. As a consequence, there can be some difficulties in observing violation of the Bell's inequality for the atomic internal variables. These difficulties persist even if the atoms travel an antinodal region, except when the spatial wave packets are exactly centered in an antinodal point.

We show that the error made when using the original formula tends to zero as $p \rightarrow 0$ and we estimate the maximum relative error to be $\sim 5\%$ if the density discontinuity is at larger densities.

A pulsar outer gap model with trans-field structure

description: We investigate the electrodynamics of an outer gap in the meridional plane of the aligned-rotator. The charge depletion from the Goldreich-Julian charge density causes a large electric field along the magnetic field line. The electrons or the positrons are accelerated by the field-aligned electric field and radiate the $γ$-rays tangentially to the local magnetic field line. Some of such $γ$-rays collide with $X$-rays to materialize as the electron-positron pairs on different field lines from the field line on which they were emitted. As a result, the electric field structure is expected to change across the field lines. Including these trans-field effects, we solve the formation of the electric field self-consistently with the curvature radiation and the pair creation processes. The $γ$-ray emission and the pair creation are treated by use of Monte Carlo technique. We demonstrate that the distribution of the electric field along the field lines is affected by both the gap geometry and the external currents coming into the gap through the boundaries. In the electrodynamical model, it has been known that the solution disappears if the current density carried by the electron-positron pairs produced in the gap exceeds a critical value. We show that the critical current density is significantly increased when the trans-field structure is taken into account. We also find that the location of the inner boundary of the gap shifts toward the stellar surface from the conventional null surface as the current density increases. The reason for the shift is derived from the stability condition of the inner boundary. We also argue that the ideal-MHD condition holds outside of the gap only when the low energy particles coexist with the high energy particles migrating from the gap.

description: Study of profitability and risk of agricultural banks is very important in assessing the ability to adequately finance agricultural production and rural development. A recursive system of profitability and risk equations is estimated to compare the performance of agricultural with nonagricultural banks and to identify factors which affect performance. A linear regression model which measures risk-adjusted profitability confirms the results from the recursive system. Results show that agricultural banks perform better than nonagricultural counterparts on average even after controlling for risks and other factors. Further, off-balance-sheet business is found to be negatively related to the risk-adjusted profitability of agricultural banks.

description: At present, plant-based hard capsule such as hydroxypropyl methylcellulose (HPMC) has a high demand in drug delivery application but the production process is expensive with limited reactant supply. κ-carrageenan has been used as a gelling agent in HPMC hard capsule production. This study aims to develop gum Arabic (GA)-κ-carrageenan biocomposite, a potential material to produce hard capsule. The GA-κ-carrageenan biocomposite films were prepared at different κ-carrageenan weight ratios of 33% (GC33), 50% (GC50) and 67% (GC67) at constant concentration of polyethylene glycol and alginate. The control films of GA film and κ-carrageenan film were compared. The film and hard capsule formed from GC67 shows the highest tensile strength and capsule loop of 36.21 MPa and 34.11 N, respectively at 1058 mPa.s solution viscosity at 300 rpm shear rate. The hard capsule disintegrated at 7.30 min. The addition of GA is compatible to make the hard capsule surface smoother. Thus, this biocomposite has the potential to be developed for future hard capsule.

description: We present a semi-relativistic model for the description of the ionization process of atomic hydrogen by electron impact in the first Born approximation by using the Darwin wave function to describe the bound state of atomic hydrogen and the Sommerfeld-Maue wave function to describe the ejected electron. This model, accurate to first order in $Z/c$ in the relativistic correction, shows that, even at low kinetic energies of the incident electron, spin effects are small but not negligible. These effects become noticeable with increasing incident electron energies. All analytical calculations are exact and our semi-relativistic results are compared with the results obtained in the non relativistic Coulomb Born Approximation both for the coplanar asymmetric and the binary coplanar geometries.

description: We investigate the role of time delay in cold-damping optomechanics with multiple mechanical resonances. For instantaneous electronic response, it was recently shown in \textit{Phys. Rev. Lett. \textbf{123}, 203605 (2019)}, that a single feedback loop is sufficient to simultaneously remove thermal noise from many mechanical modes. While the intrinsic delayed response of the electronics can induce single mode and mutual heating between adjacent modes, we propose to counteract such detrimental effects by introducing an additional time delay to the feedback loop. For lossy cavities and broadband feedback, we derive analytical results for the final occupancies of the mechanical modes within the formalism of quantum Langevin equations. For modes that are frequency degenerate collective effects dominate, mimicking behavior similar to Dicke super- and subradiance. These analytical results, corroborated with numerical simulations of both transient and steady state dynamics, allow to find suitable conditions and strategies for efficient single or multimode feedback optomechanics.

description: We discuss the formation of graded morphogen profiles in a cell layer by nonlinear transport phenomena, important for patterning developing organisms. We focus on a process termed transcytosis, where morphogen transport results from binding of ligands to receptors on the cell surface, incorporation into the cell and subsequent externalization. Starting from a microscopic model, we derive effective transport equations. We show that, in contrast to morphogen transport by extracellular diffusion, transcytosis leads to robust ligand profiles which are insensitive to the rate of ligand production.

description: A study of the micromechanical unzipping of DNA in the framework of the Peyrard-Bishop-Dauxois model is presented. We introduce a Monte Carlo technique that allows accurate determination of the dependence of the unzipping forces on unzipping speed and temperature. Our findings agree quantitatively with experimental results for homogeneous DNA, and for $λ$-phage DNA we reproduce the recently obtained experimental force-temperature phase diagram. Finally, we argue that there may be fundamental differences between {\em in vivo} and {\em in vitro} DNA unzipping.

description: This study examined the role of consumers' perceived risks and benefits of agro-biotechnology in shaping the purchase pattern for organic food among US consumers. Consumers' general purchase behavior, knowledge of GM technology, and socio-demographic variables were examined in relation to their impact on organic food purchase. The sample data indicated that less than one fourth of the consumers bought organic products at least sometimes. Only 2% of the consumers bought organic food very often. Perceived risks of agro-biotechnology played a dominant role in influencing organic food purchase decisions. Consumers who were concerned about negative attributes of agro-biotechnology including long-term health and environmental hazards, inequity in the distribution of benefits from the technology, and adverse effects to small and medium farms were the potential organic food consumers. Benefits of agro-biotechnology did not play an important role in shaping the purchase pattern for organic food. Food safety was the most important consideration while making organic food purchase decisions. Importance of food safety while making food purchase decisions and consumers' trust in the ability of grocery stores to supply safe food were other important factors in determining purchase pattern for organic foods. In this study, prices of food products did not play important role in determining purchase pattern for organic foods. Growth in organic food market is largely dependent on continued reinforcement of consumers' belief that organic foods are safer than conventional foods

description: Superconducting fluctuations in long and narrow strips made from ultrathin NbN films, have been investigated. For large bias currents close to the critical current fluctuations led to localized, temporary transitions into the normal conducting state, which were detected as voltage transients developing between the strip ends. We present models based on fluctuations in the Cooper pair density and current-assisted thermal-unbinding of vortex-antivortex pairs, which explain the current and temperature dependence of the experimental fluctuation rates.

description: Design and simulation of air-solar-finned reheating unit, an innovative design of a parabolic trough solar collector (PTSC) has been demonstrated in this work. Fundamentally, the design equations were formulated on the optical and thermal principles. The fundamental optical equations were transformed and equated with the original optical equations to realize the optical design functions. The design variables appear in the design function as the unknowns. The design functions were differentiated with respect to the design variables to form design simulatory matrices. Prior to the simulation, the design functions were made to approach zero by the introduction of convergent factors which guarantee the convergence of the simulatory matrices whose final output defines the design variables. The design was algorithmized with a flowchart to justify the design procedures. A slight obtuse-angled rim design was adopted in the design of the reheating unit (RU) which yielded optimum; rim angle of 94°, collector, optical and thermal efficiencies of 0.44, 0.72 and 0.31, respectively, and an optimum exit fluid temperature of 110oC sequel to the simulation of the design equations. Besides, the apparent tradeoffs among the design variables were useful in making design decisions. Considering the pitfalls of the traditional acute-angled rim design (AARD), the present work is advocating for the adoption of slight obtuse-angled rim design (SOARD) technique which will shield the PTSCs from the misalignment issues and equally minimize the thermal losses prone to the acute-angled rim design technique. Also, premium on material selection is recommended for the effective operation of RU.

Condensation and coexistence in a two-species driven model

description: Condensation transition in two-species driven systems in a ring geometry is studied in the case where current-density relation of a domain of particles exhibits two degenerate maxima. It is found that the two maximal current phases coexist both in the fluctuating domains of the fluid and in the condensate, when it exists. This has a profound effect on the steady state properties of the model. In particular, phase separation becomes more favorable, as compared with the case of a single maximum in the current-density relation. Moreover, a selection mechanism imposes equal currents flowing out of the condensate, resulting in a neutral fluid even when the total number of particles of the two species are not equal. In this case the particle imbalance shows up only in the condensate.
