description: We reanalyze the formation and evolution of galaxies in the hierarchical clustering scenario. Using a semi-analytic model (SAM) of galaxy formation described in this paper, which we hereafter call the Mitaka model, we extensively investigate the observed scaling relations of galaxies among photometric, kinematic, structural and chemical characteristics. In such a scenario, spheroidal galaxies are assumed to be formed by major merger and subsequent starburst, in contrast to the traditional scenario of monolithic cloud collapse. As a new ingredient of SAMs, we introduce the effects of dynamical response to supernova-induced gas removal on size and velocity dispersion, which play an important role on dwarf galaxy formation. In previous theoretical studies of dwarf galaxies based on the monolithic cloud collapse given by Yoshii & Arimoto and Dekel & Silk, the dynamical response was treated in the extremes of a purely baryonic cloud and a baryonic cloud fully supported by surrounding dark matter. To improve this simple treatment, in our previous paper, we formulated the dynamical response in more realistic, intermediate situations between the above extremes. While the effects of dynamical response depend on the mass fraction of removed gas from a galaxy, how much amount of the gas remains just after major merger depends on the star formation history. A variety of star formation histories are generated through the Monte Carlo realization of merging histories of dark halos, and it is found that our SAM naturally makes a wide variety of dwarf galaxies and their dispersed characteristics as observed.

Year: 2014

description: The purpose of this report is to propose revised and updated metrics for the “AMS Lighter Footprints Strategy” (AMSLFS) document that was created in 2008 (Baker-French, 2013). The new findings will be achieved through conducting an assessment of the current targets outlined in the AMSLFS document, thus determining if they are still measurable and applicable in the context of the new Student Union Building (SUB) (Baker-French, 2013). The report will highlight the methods used to gather the research in order to make the appropriate recommendations to the key stakeholders. Methods include a literature review, key informant interviews, and a focus group. Further, notes gathered from a guest lecture on Logic Models are applied to help organize and coordinate the programs and actions plans under review. In our analysis we determine whether targets outlined in the AMSLFS document are still relevant to the new SUB. When targets were deemed still appropriate our conclusions propose applicable and actionable revisions and actions along with associated inputs, outputs and possible outcomes.

Discontinuity gravity modes in hybrid stars: assessing the role of rapid and slow phase conversions

description: Discontinuity gravity modes may arise in perturbed quark-hadron hybrid stars when a sharp density jump exists in the stellar interior and are a potential fingerprint to infer the existence of quark matter cores in compact objects. When a hybrid star is perturbed, conversion reactions may occur at the quark-hadron interface and may have a key role in global stellar properties such as the dynamic stability and the quasi-normal mode spectrum. In this work we study the role of the conversion rate at the interface. To this end, we first derive the junction conditions that hold at the sharp interface of a non-radially perturbed hybrid star in the case of slow and rapid conversions. Then, we analyse the discontinuity $g$-mode in both cases. For rapid conversions, the discontinuity $g$-mode has zero frequency because a displaced fluid element near the phase splitting surface adjusts almost immediately its composition to its surroundings and gravity cannot provide a buoyancy force. For slow conversions, a $g$-mode exists and its properties are analysed here using modern hadronic and quark equations of state. Moreover, it has been shown recently that in the case of slow conversions an extended branch of stable hybrid configurations arises for which $\partial M/ \partial ε_c <0$. We show that $g$-modes of the standard branch (that is, the one with $\partial M/ \partial ε_c > 0$) have frequencies and damping times in agreement with previous results in the literature. However, $g$-modes of the extended branch have significantly larger frequencies (in the range $1-2 \, \mathrm{kHz}$) and much shorter damping times (few seconds in some cases). We discuss the detectability of $g$-mode GWs with present and planned GW observatories.

description: We introduce new classes of hydrodynamic theories inspired by the recently discovered fracton phases of quantum matter. Fracton phases are characterized by elementary excitations (fractons) with restricted mobility. The hydrodynamic theories we introduce describe thermalization in systems with fracton-like mobility constraints, including fluids where charge and dipole moment are both locally conserved, and fluids where charge is conserved along every line or plane of a lattice. Each of these fluids is subdiffusive, and constitutes a new universality class of hydrodynamic behavior. There are infinitely many such classes, each with distinct subdiffusive exponents, all of which are captured by our formalism. Our framework naturally explains recent results on dynamics with constrained quantum circuits, as well as recent experiments with ultracold atoms in tilted optical lattices. We identify crisp experimental signatures of these novel hydrodynamics, and explain how they may be realized in near term ultracold atom experiments.

title: State rescaling and infrastructure imaginaries: transport devolution in England's 'Northern Powerhouse'
Creators: name: Arnold, Thomas
Publisher: name: University of Liverpool Repository
Year: 2022

description: This thesis examines the impact of sub-national transport devolution in Northern England on institutional relationships between different tiers of government. The establishment in 2015 of Transport for the North (TfN) represents a rescaling of strategic transport planning powers in Northern England, as part of the 'Northern Powerhouse' agenda which aims to spatially rebalance England's economy through improvements to transport infrastructure and sub-national devolution. Exploring the formal and informal institutional influences that determine the choices available to local and sub-national actors, the research assesses the effect of rescaling on interactions between local government, national government and TfN itself. Using data from interviews with elite policymakers operating at the national, sub-national and local tiers of transport planning, along with analysis of key policy documents, the research identifies a range of strategies and tactics deployed by actors and organisations operating at different tiers of England's multi-level system of transport planning governance. A case study of West Yorkshire is used to assess local responses to TfN's development of a Strategic Development Plan and proposals for the totemic Northern Powerhouse Rail project. The research findings are assessed in the context of the UK's unusually centralised approach to infrastructure planning and funding to explore how state power shapes and constrains the choices available to planners involved in sub-national and local transport planning. The informal institutions governing the policy activity of sub-national actors, and their autonomy in responding to and interpreting rescaling of transport planning powers, are examined. The research explores TfN's planning and political activity in the context of its relationship with central government, while at the local scale political actors have responded to the establishment of TfN by employing a range of methods to promote their infrastructure priorities. The spatial, institutional and political ramifications of state rescaling are discussed and the socio-spatial objectives and outcomes of regional transport infrastructure strategies are analysed in the context of England's unusually centralised system of government. The thesis adopts an infrastructural lens to examine the effects of state rescaling and advances understanding of the informal institutions that influence the development of sub-national policy.

description: The proposed linear electron-positron collider TESLA is based on 1.3 GHz superconducting niobium cavities for particle acceleration. For a centre-of-mass energy of 500 GeV, an accelerating field of 23.4 MV/m is required which is reliably achieved with a niobium surface preparation by chemical etching. An upgrade of the collider to 800 GeV requires an improved cavity preparation technique. In this paper, results are presented on single-cell cavities which demonstrate that fields of up to 40 MV/m are accessible by electrolytic polishing of the inner surface of the cavity.

description: It is a well known that not all trade in southern Africa is recorded. Recorded trade therefore gives a skew picture and this paper specifically attempts to estimate and inv~stigate unrecorded tJ:ade in th~ region, using the grain ~arket and the "grain trade ratio". Unrecorded trade occurred m most southern ~ca countries and ~o recorded. ~de JS observed for South Africa during the period 1986-1991. This corresponds to the time when South Afl:ica was p~hti~lly exclu~ed from formal trading in southern Africa. The grain trade ratio (grain trade as percentage of gram production) JS decreasing. The paper examines why the trade ratio decreased when national policies emphasized local food production programmes, market liberalization and more open trade in the region.
An Updated Galactic Double Neutron Star Merger Rate Based on Radio Pulsar Populations

description: Following the procedure described in Pol et al., we update the Galactic double neutron star (DNS) merger rate by including the new, highly eccentric DNS system J0509+3801 (Lynch et al.). This leads to a new Galactic DNS merger rate of $\mathcal{R}_{\rm MW} = 37^{+24}_{-11}$ Myr$^{-1}$, where the errors represent 90% confidence intervals. The corresponding DNS merger detection rate for Advanced LIGO is $\mathcal{R} = 1.9^{+1.2}_{-0.6} \times \left( D_{\rm r} / 100 \ \rm Mpc \right)^3 \rm yr^{-1},$ where $D_{\rm r}$ is the range distance. Using the LIGO O3 range distance of 130 Mpc (Abbott et al.), we predict that LIGO will detect anywhere between three and seven DNS mergers per year of observing at O3 sensitivity.

description: This paper investigates the relationship between land tenure security and credit use, investments in land improvements and complementary short-tenn input use, and yields in small scale agriculture. Data for the study were gathered by means of a smvey interview of fanners in the Small Scale Commercial Sector, Resettlement Areas and Communal Areas of Zimbabwe. Descriptive statistics indicate that investments in land improvements and short term input use is greatest in areas where tenure is most secure. Households lacking exclusive and assured land rights have little incentive to invest in agriculture. However, little evidence supporting the benefits of land titling is provided.
Type Ia supernovae in a hierarchical galaxy formation model: the Milky Way
Creators: name: Nagashima, Masahiro

Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)

description: We investigate chemical evolution in Milky Way-like galaxies based on the cold dark matter model in which cosmic structures form via hierarchical merging. We introduce chemical enrichment due to type Ia supernovae (SNe Ia) into the Mitaka semi-analytic galaxy formation model developed by Nagashima & Yoshii. For the first time we derive distributions of stellar metallicities and their ratios in Milky Way-like galaxies treating chemical enrichment due to SNe Ia in a hierarchical galaxy formation model self-consistently. As a first attempt, we assume all SNe Ia to have the same lifetime, and assume instantaneous recycling for type II supernovae (SNe II). We find that our model reproduces well the metal abundance ratio [O/Fe] against [Fe/H] and the {iron metallicity distribution function} in the solar neighborhood. This means that the so-called G-dwarf problem is resolved by the hierarchical formation of galaxies, and a gas infall term introduced in traditional monolithic collapse models to solve this problem is well explained by the mixture of some physical processes such as hierarchical merging of dark halos, gas cooling, energy feedback and injection of gas and metals into hot gas due to supernovae. Our model predicts more oxygen-enhanced stars in bulges at [Fe/H] $\simeq 0$ than in disks. This trend seems to be supported by recent observations while they have still uncertainties. More data in number and accuracy will provide independent and important constraints on galaxy formation. (abridged)

description: In this paper we analyze nuclear medium effects on DVCS amplitudes in the $\Bx$ range of $0.1-0.0001$ for a large range of $Q^2$ and four different nuclei. We use our nucleon GPD model capable of describing all currently available DVCS data on the proton and extend it to the nuclear case using two competing parameterizations of nuclear effects. The two parameterizations, though giving different absolute numbers, yield the same type and magnitude of effects for the imaginary and real part of the nuclear DVCS amplitude. The imaginary part shows stronger nuclear shadowing effects compared to the inclusive case i.e. $F^N_2$, whereas in the real part nuclear shadowing at small $\Bx$ and anti-shadowing at large $\Bx$ combine through evolution to yield an even greater suppression than in the imaginary part up to large values of $\Bx$. This is the first time that such a combination of nuclear effects has been observed in a hadronic amplitude. The experimental implications will be discussed in a subsequent publication.

description: The feasibility and consequences of small-scale (1-2 hectare) apple production systems are examined as a contribution to the dialogue on agricultural and rural transformation in the Western Cape. The most important constraint facing emerging fanners is assumed to be start-up capital. An expert panel of scientists and commercial apple farmers were drawn into an interactive, computer assisted dialogue to design alternative apple production systems requiring significantly scaled-down investment. Within imposed capital constraints, production technologies were designed using horticultural integrity and feasibility as criteria. Each model was then subjected to economic analysis. Net present values for 10 and 20 year orchard lives, internal rates of return and other criteria are applied. The analysis explores feasibility within the particular constraints of small-scale farming such as available household labour and risk averseness. One model passes most feasibility tests under a wide range of conditions. Assumptions within that model should form important considerations for small farmer establishment programs. Lastly, a portrait of a possible two hectare apple farm is presented.

description: Rental markets for agricultural land in communal areas of Southern Africa are often constrained, despite potential benefits for many households. High transaction costs and insecure tenure have precluded active rental markets in the region. The notion that conditions necessary for land rental will emerge in response to increasing population pressure and better prospects in farming is questioned. Attention is focused on interest groups opposed to changes in customary tenure, and policies designed to 'supply the institutional changes needed to support an active rental market. The main conclusion is that farmer support programmes are unlikely to realise their full potential unless they are accompanied by adaptive strategies that make endogenous changes in customary tenure more predictable.

description: The linear-frictional contact model is the most commonly used contact mechanism for discrete element (DEM) simulations of granular materials. Linear springs with a frictional slider are used for modeling interactions in directions normal and tangential to the contact surface. Although the model is simple in two dimensions, its implementation in 3D faces certain subtle challenges, and the particle interactions that occur within a single time-step require careful modeling with a robust algorithm. The paper details a 3D algorithm that accounts for the changing direction of the tangential force within a time-step, the transition from elastic to slip behavior within a time-step, possible contact sliding during only part of a time-step, and twirling and rotation of the tangential force during a time-step. Without three of these adjustments, errors are introduced in the incremental stiffness of an assembly. Without the fourth adjustment, the resulting stress tensor is not only incorrect, it is no longer a tensor. The algorithm also computes the work increments during a time-step, both elastic and dissipative.

description: Working with UBC SEEDS and UBC Botanical Garden, our team was tasked with proposing an efficient and cost effective solution to the issue of seasonal flow rate variations in Rock Creek at the UBC Botanical Garden, which have raised concerns regarding flooding, erosion, and aesthetics of the stream. Through our three months endeavor, we have examined pre-existing information, conducted research on methods of flow rate control, and gathered other details regarding the stream as required. From this information, we have formulated a series of suggestions for mediating seasonal flow rate variations and controlling the associated problems. We also conducted proper surveying for the stream and were able to map out the elevation profile for the stream; the total elevation drop across the stream is approximately 7.5m over a 93m length. Four locations of steep elevation drop in the stream were also identified. Through analysis of past local precipitation data, we have determined that there is indeed a very large seasonal fluctuation in expected flow rate in Rock Creek; precipitation rates are generally between 5mm to 15mm per day during the winter and spring months between October and June, while summer precipitation is negligible. Average flow rate for Rock Creek I was found to be 13.45L/s, and based on the data, the flow rate strongly correlates with the trend seen in precipitation. After considering the characteristics of the stream, we have outlined four solutions, which are as follows: adding a permeable holding pond at the top of the stream, rock weir placement along the upper half of the stream, stream bed roughening along the lower half of the stream, and riprap installation along the sides of the stream. These proposed ideas are explored in detail in the following report, explaining the purpose, design, cost, drawbacks, and possible improvements of each.

description: We highlight in a model independent way the dependence of the effective Majorana mass parameter, relevant for neutrinoless double beta decay, on the CP phases of the PMNS matrix, using the most recent neutrino data including the cosmological WMAP measurement. We perform our analysis with three active neutrino flavours in the context of three kinds of mass spectra: quasi-degenerate, normal hierarchical and inverted hierarchical. If a neutrinoless double beta decay experiment records a positive signal, then assuming that Majorana masses of light neutrinos are responsible for it, we show how it might be possible to discriminate between the three kinds of spectra.

Production Economics

description: Lesotho is a very small producer of wool (1 thousand tonnes per year) and therefore has no influence on world prices and on world wool production. However, the earnings generated from wool exports contribute significantly to the economy, thus making wool an important product. This paper determines the factors that producers consider in their decisions to produce wool. An econometric supply model is developed which hypothesizes the variables that affect wool production. Lagged wool and mohair prices and rainfall are important variables that influence farmers' decisions to produce wool. The previous years' wool production is less important because of the biological lag associated with production. Other variables such as the marketing arrangements of wool and domestic policies might influence farmers' decisions to produce wool but were not considered in detail.

description: The term "bamboo rice" refers to the seeds of bamboo plants, Bambusa arundinacea. Certain bamboo seeds resemble rice grains in appearance. The brown seeds of the native bamboo species in India, after being dehusked, resemble rice grains. Bamboo rice refers to the unique form of rice seeds that bloom when the bamboo shoot finally dies. Consumption of bamboo rice has a long history and is still popular in areas like southwest China, northeastern India, and southern India. Bamboo seeds are high in nutrients and have ingredients that are good for people's health. Bamboo seeds are used in some tribal areas as an aphrodisiac and to cure urinary tract and digestive issues. Bamboo rice can be utilized for preparation of noodles, kheer mix, payasam, idli, porridge, cookies etc. Still there are many opportunities to explore as to how this functional food ingredient can be promoted for increasing the revenue of farming community.

description: If an extension Vbar of V satisfies the delta approximation and cover properties for classes and V is a class in Vbar, then every suitably closed embedding j:Vbar to Nbar in Vbar with critical point above delta restricts to an embedding j|V:V to N amenable to the ground model V. In such extensions, therefore, there are no new large cardinals above delta. This result extends work in math.LO/9808011.

description: A re-entrant novel phase has been observed in the hexagonal ferroelectric HoMnO3 in the presence of magnetic fields, in the temperature ranges defined by the plateau of the dielectric constant anomaly. The dielectric plateau evolves with fields from a narrow sharp dielectric peak at the Mn-spin rotation transition at 32.8 K in zero magnetic field. Such a field-induced dielectric plateau anomaly appears both in the temperature sweep at a constant field and in the field sweep at a constant temperature without detectable hysteresis. This is attributed to the indirect coupling between the ferroelectric and antiferromagnetic orders, arising from an antiferromagnetic domain wall effect, where the magnetic order parameter of the Mn subsystem has to change sign across the ferroelectric domain wall in the compound, that influences the ferroelectric domains via a local magnetostrictive effect.

description: $ππ$ scattering length in the I=2 channel is calculated within quenched approximation using improved gauge and improved Wilson fermion actions on anisotropic lattices. The results are extrapolated towards the chiral, infinite volume and continuum limit. This result improves our previous result on the scattering length. In the chiral, infinite volume and continuum limit, we obtain $a^{(2)}_0m_π=-0.0467(45)$, which is consistent with the result from Chiral Perturbation Theory, the experiment and results from other lattice calculations.

description: Marketing of small farmer produce has been fraught with many difficulties and disappointments despite concerted efforts of government, non-government and private sector organisations and development corporations. There are many and varied reasons for this, one of which is the lack of appreciation of the culture, customs and traditions of the small farmer. This paper draws on experiences from a rural area in Mpumalanga Province to describe the influence of tradition on the production and marketing of small fanner produce, problem areas, and possible solutions by evaluating critical criteria in the light of traditional values. These criteria include training, information systems, market structures and product research and development. The need for a closer relationship between small fanner and advisor is identified as a key to the sustainable use of resources for the long-term human and economic stability of rural communities and the country.

description: Farmers commercialize in order to acquire other goods. Commercialization leads to improved production and welfare, accelerates linkages and eases fmancing conditions. Logit models were estimated to determine socio-economic factors that distinguish more commercially oriented farmers from moderately commercial and less commercial farmers. The more commercial fanners are more likely to have used credit, formal marketing channels, kept farming records, listened to agricultural information. These fanners require more land. The less commercial groups require a comprehensive approach that include credit and market facilities, input and technology transfers, training, price guarantees and crop insurance. The objective should be to achieve overall commercialisation.

description: Strain localization and resulting plasticity and failure play an important role in the evolution of the lithosphere. These phenomena are commonly modeled by Stokes flows with viscoplastic rheologies. The nonlinearities of these rheologies make the numerical solution of the resulting systems challenging, and iterative methods often converge slowly or not at all. Yet accurate solutions are critical for representing the physics. Moreover, for some rheology laws, aspects of solvability are still unknown. We study a basic but representative viscoplastic rheology law. The law involves a yield stress that is independent of the dynamic pressure, referred to as von Mises yield criterion. Two commonly used variants, perfect/ideal and composite viscoplasticity, are compared. We derive both variants from energy minimization principles, and we use this perspective to argue when solutions are unique. We propose a new stress-velocity Newton solution algorithm that treats the stress as an independent variable during the Newton linearization but requires solution only of Stokes systems that are of the usual velocity-pressure form. To study different solution algorithms, we implement 2D and 3D finite element discretizations, and we generate Stokes problems with up to 7 orders of magnitude viscosity contrasts, in which compression or tension results in significant nonlinear localization effects. Comparing the performance of the proposed Newton method with the standard Newton method and the Picard fixed-point method, we observe a significant reduction in the number of iterations and improved stability with respect to problem nonlinearity, mesh refinement, and the polynomial order of the discretization.

description: The influence of dynamical correlation effects on the magneto-optical properties of ferromagnetic Fe and Ni has been investigated. In addition the temperature dependence of the self-energy and its influence on the DOS and optical conductivity is considered. Magneto-optical properties were calculated on the basis of the one-particle Green's function, which was obtained from the DMFT-SPTF procedure. It is shown that dynamical correlations play a rather important role in weakly correlated Fe and substantially change the spectra for moderately correlated Ni. Magneto-optical properties obtained for both systems are found in better agreement with experiment than by conventional LDA calculations.
