description: A search for single top quark production via flavour changing neutral currents (FCNC) was performed with data collected by the OPAL detector at the e+e- collider LEP. Approximately 600 pb-1 of data collected at sqrt(s) = 189 - 209 GeV were used to search for the FCNC process e+ e- -> tc(u) -> bWc(u). This analysis is sensitive to the leptonic and the hadronic decay modes of the W boson. No evidence for a FCNC process is observed. Upper limits at the 95% confidence level on the single top production cross-section as a function of the centre-of-mass energy are derived. Limits on the anomalous coupling parameters kappa_gamma and kappa_Z are determined from these results.

description: An AC electric field applied to a junction comprising two spin-orbit coupled weak links connecting a quantum dot to two electronic terminals is proposed to induce a DC current and to generate a voltage drop over the junction if it is a part of an open circuit. This photovoltaic effect requires a junction in which mirror reflection-symmetry is broken. Its origin lies in the different fashion inelastic processes modify the reflection of electrons from the junction back into the two terminals, which leads to uncompensated DC transport. The effect can be detected by measuring the voltage drop that is built up due to that DC current. This voltage is an even function of the frequency of the AC electric field and is {\em not} related to quantum pumping.

description: An overview is given of the experimental neutrino mixing results and types of neutrino models proposed, with special attention to the general features of various GUT models involving intra-family symmetries and horizontal flavor symmetries. Many of the features are then illustrated by a specific SO(10) SUSY GUT model formulated by S.M. Barr and the author which can explain all four types of solar neutrino mixing solutions by various choices of the right-handed Majorana mass matrix. The quantitative nature of the model's large mixing angle solution is used to compare the reaches of a neutrino super beam and a neutrino factory for determining the small U_{e3} mixing matrix element.

description: We study the commutators of the kappa-deformed Poincare Algebra (kappaPA) in an arbitrary basis. It is known that the two recently studied doubly special relativity theories correspond to different choices of kappaPA bases. We present another such example. We consider the classical limit of kappaPA and calculate particle velocity in an arbitrary basis. It has standard properties and its expression takes a simple form in terms of the variables in the Snyder basis. We then study the particle trajectory explicitly for the case of a constant force. Assuming that the spacetime continuum, velocity, acceleration, etc. can be defined only at length scales greater than x_{min} ne 0, we show that the acceleration has a finite maximum.

Demand and Price Analysis

description: A survey of two rural markets in southwest Nigeria over 14 months showed that supplies, sales and prices of sheep and goats varied widely during the period with a sharp peak during the Muslim festival of Eid-e1-Kabir and a smaller peak during the Christmas-New Year period. Local West African Dwarf (WAD) sheep and goats and northern Y' ankasa sheep and Red Sokoto goats were traded in the markets and animals were purchased for rearing, trading, ceremonies, butchering/ catering, sacrifice, and festivals. There were significant differences between species /breeds purchased for various purposes. A hedonic price model was fitted to determine factors influencing price. After adjustments were made for age, weight, sex, time of transaction and market, WAD sheep commanded higher prices than WAD goats and Red Sokoto goats for all purposes except for butchering/ catering; Red Sokoto goats commanded similar or lower prices than WAD goats depending on the purpose for purchase; and Y'ankasa sheep, principally purchased for the Eid-el-Kabir festival, commanded marginally higher prices than WAD sheep. The market share of WAD sheep is currently small and is under competition from northern sheep and goats, so increased production of WAD sheep in the south will benefit both producers and consumers in the area. In general, the results indicate that buyers have preferences for specific breeds and species for specific purposes, so producers and sellers may benefit by targeting specific buyer categories and times of the year.

description: Titanium carbide (TiC) nanowires are synthesized by carbothermal reduction reaction at 1473–1673 K in argon atmosphere. The structure and morphology of TiC nanowires are characterized by X-ray diffraction (XRD) and field emission scanning electron microscopy (FE-SEM). The chemical reaction thermodynamics and the growth mechanism of TiC nanowires are investigated based on the Ti-C-O-Cl system. It involves the formation of gaseous TiClx and CO crucial intermediates, and the further carbon reduction of TiClx to TiC. Based on the thermodynamic analysis, the two-stage growth mechanism of TiC nanowires is discussed. The work could help to analyze the thermochemistry of the carbothermal reduction reaction in the Ti-C-O-Cl system, which is beneficial to optimize the temperature and the input precursors for controlling TiC nanowires growth.
Predicting Cardiovascular Disease Risk in Chronic Kidney Disease

description: Chronic kidney disease (CKD) is a long term condition in which glomerular filtration is reduced and/or proteinuria occurs. Cardiovascular risk factors in CKD are different to the general population and overall risk is higher too. Therefore, risk prediction tools for cardiovascular disease require specific validation in CKD.The Leicester City and County CKD (LCC) cohort of 17,248 anonymised individuals with CKD from 44 general practices was established. Cardiovascular events were identified from general practice and hospital records, and 2,072 cardiovascular events occurred during five years of follow-up.Risk factors for cardiovascular events in CKD were identified in a systematic review and a second systematic review updated a previous systematic review of risk prediction tools for cardiovascular events in CKD. Albumin, haemoglobin and phosphate were identified as risk factors to be consider for risk prediction tools in addition to factors included in general population risk prediction tools. Seven CKD-specific and six general population risk prediction models were identified. All models were developed using the Cox proportional hazards (‘Cox’) model.The LCC cohort was used to externally validate these models. Discrimination was worse and calibration suggested overprediction of risk in all models. The latter worsened as predicted risk increased. Some calibration improvement was achieved through Cox model baseline risk function re-estimation. There was no significant risk prediction improvement by including the variables identified in the systematic review. Sensitivity analysis suggested that the Cox model’s censoring at random assumption may have been violated in the risk prediction models due to the competing risk from death.Risk prediction models for cardiovascular events in people with CKD require improvement and updating to optimise risk prediction accuracy. Alternative methods, such as multi-state models, should be considered in future model development.

description: This work analyzes fractional continuous-time random walks on two-layer multiplexes. A node-centric dynamics is used, in which it is assumed a Poisson distribution of a walker to become active, while a jump to one of its neighbors depends on the connection weight. Synthetic multiplexes with well known topology are used to illustrate dynamical features obtained by numerical simulations, while exact analytical expressions are presented for multiplexes assembled by circulant layers with finite number of nodes. Special attention is given to the effect of inter- $D_x$ and intra-layer $D_i$ coefficients on the system's behavior. In opposition to usual discrete time dynamics, the relaxation time has a well defined minimum at an optimal value of $D_x/D_i$. It is found that, even for the enhanced diffusion condition, the walkers mean square displacement increases linearly with time.

Kinesis In Animal Dispersal: Dependence Of Diffusion On Reproduction Coefficient

Publisher: name: University of Leicester
Year: 2019
Subjects: Uncategorized

description: Migration and dispersal of animals has evolved under the control of natural selection. In a simple formalisation, the strategy of dispersal should increase Darwinian fitness. In this dissertation, we aim to introduce and analyse new models of purposeful kinesis with diffusion coefficient dependent on fitness. New models include one additional parameter, intensity of kinesis, and may be considered as the minimal models of purposeful kinesis. It is demonstrated how kinesis could be beneficial for assimilation of patches of food or of periodic fluctuations. Nevertheless, kinesis, based on local and instantaneous estimations of fitness, is not always beneficial in the long-term and spatially global perspective: for example, for species with the Allee effect it can delay invasion and spreading. It is proven that kinesis cannot modify stability of homogeneous positive steady states. In the proposed basic model, mobility decreases for high reproduction coefficient. Therefore, animals stay longer in good conditions and leave quicker bad conditions. Accounting for the cost of mobility in the reproduction ratio leads to an equation for mobility. It can be solved in a closed form using Lambert W-function. These models with the simple linear cost of mobility have an intrinsic phase transition: when conditions worsen then the mobility increases up to some critical value of the reproduction coefficient. For worse conditions, there is no solution for mobility. We interpret this bifurcation as the complete loss of mobility that is degeneration of diffusion. Mobility increases with worsening of conditions up to some limit, and after that, mobility nullifies. We analyse the impact of the purposeful kinesis model on running waves. Both monotonic and non-monotonic (the Allee effect) dependence of the reproduction coefficient on the population density are studied. The possible benefits of the purposeful kinesis are demonstrated: with the higher diffusion, while the population without kinesis ends up with extinction, the population with kinesis stays alive and has the running wave behaviour.
Performance of Adhesive and Cementitious Anchorage Systems

description: Post-installed anchoring systems are used extensively in Massachusetts Department of Transportation (MassDOT) projects due their ease of attachment to existing structures. However, recommendations on materials from various manufacturers are currently lacking for certain situations such as long-term tension loading. The purpose of the investigation presented in this thesis was to provide guidance on the use of anchoring systems to MassDOT. This research project evaluated the behavior of adhesive and cementitious bonded anchoring systems per the Stress-versus-Time-to-Failure approach found in the provisional standard AASHTO TP-84 in order to provide recommendations pertaining to the test method. Supplemental short-term anchor pullout tests were conducted using the best performing materials as evaluated by AASHTO TP-84 to study the effects of certain in-service and installation parameters on bond strength. The parameters studied included installation direction and extreme in-service temperatures. Polymer characterization testing of adhesive products were also conducted in order to comment on technique usefulness for field quality assurance/quality control of field installed bonded anchor materials.

description: Trees can be considered as investments made by economic agents to prevent depreciation of natural assets such as stocks of top soil and water. In agroforestry systems farmers use trees in this manner by deliberately combining them with agricultural crops on the same unit of land. Although advocates of agroforestry have asserted that soil conservation is one of its primary benefits, empirical estimates of these benefits have been lacking due to temporal and spatial complexity of agroforestry systems and the nonmarket aspect of soil capital assets. This study designs and applies a bio-economic framework for valuing the soil conservation benefits of agroforestry. The framework is tested with econometric analysis of data from surveys of households in Eastern Visayas, Philippines, where USAID /Government of Philippines introduced contour hedgerow agroforestry in 1983. By constructing a weighted soil quality index that also incorporates measures of soil fertility, texture and color in addition to erosion, we extend previous economic studies of soil resources. This index is regressed on a variety of farming and site specific bio-physical variables. Next, we use a Cobb-Douglas profit function to directly relate agricultural profits and soil quality. Thus, the value of soil conservation is measured as a quasi-rent differential or the share of producer surplus associated with a change in soil quality. Because this framework assumes the existence of markets, the assumption is tested by analysing the statistical significance of consumption side variables, e.g., number of household members, on production side variables, e.g., profits. Instrumental variables are used to handle the endogeneity of the soil index in the profit equation. Seemingly unrelated regression (SUR) analysis is used to accommodate correlation of errors across the soil and profit equations. Regression results reveal the importance of agroforestry intensity, private ownership, land fragmentation, and familiarity with soil conservation as positive covariates of soil quality. Analysis of production data indicate the importance of market prices, education, farming experience, farm size, topography, and soil quality as positive covariates of household profits. Investments in agroforestry to improve or maintain soil capital can increased annual agricultural profits by US$53 for the typical household, which is 6% of total income. However, there are significant up-front costs. Given that small farmers in tropical uplands are important players in the management of deteriorating soil and forest resources, policy makers may want to consider supporting farmers in the early years of agroforestry adoption.

Econ., 41: 209-221.] proposed a transactional framework of sharecropping that accommodates both the Marshallian and the Cheungian equilibria. An important conclusion arising thereof is the hypothesis that Cheung's sharecropping equilibrium is the rarity while the Marshallian equilibrium is the norm. In this paper, we collated some recent evidences to verify this hypothesis. The evidences support the Marshallian equilibrium, thereby providing indirect support for the transactional framework of sharecropping.

description: Owing to their high photon detection efficiency, compactness, and low operating voltage, silicon photomultipliers (SiPMs) have found widespread application in many fields, including medical imaging, particle physics, and high-energy astrophysics. However, the so-called optical crosstalk (OCT) phenomenon of SiPMs is a major drawback to their adoption. Secondary infrared photons are emitted inside the silicon substrate spontaneously after the avalanche process caused by the primary incident photons, and they can be detected by the surrounding photodiodes. As a result large output pulses that are equivalent to multiple photoelectrons are observed with a certain probability (OCT rate), even for single-photon events, making the charge resolution worse and increasing the rate of accidental triggers by single-photon events in applications such as atmospheric Cherenkov telescopes. In our previous study, we found that the OCT rates of single-channel SiPMs was dependent on the thickness of their protection resin window, which may be explained by photon propagation inside the resin. In the present study, we measured the OCT rate of a multichannel SiPM and those of neighboring channels caused by photon propagation. Both OCT rates were found to be dependent on the protection-window thickness. We report our OCT measurements of a multichannel SiPM and comparisons with a ray-tracing simulation.

description: We derive new exact charged $d$-dimensional black hole solutions for quadratic teleparallel equivalent gravity, $f({\cal T})=a_0+a_1{\cal T}+a_2{\cal T}^2$, where $\cal T$ is the torsion scalar, in the case of non-linear electrodynamics. We give a specific form of electromagnetic function and find out the form of the unknown functions that characterize the vielbeins in presence of the electromagnetic field. It is possible to show that the black holes behave asymptotically as AdS solutions and contain, in addition to the monopole and quadrupole terms, other higher order terms whose source is the non-linear electrodynamics field. We calculate the electromagnetic Maxwell field and show that our d-dimensional black hole solutions coincide with the previous obtained one \cite{2017JHEP...07..136A}. The structure of the solutions show that there is a central singularity that is much mild in comparison with the respective one in General Relativity. Finally, the thermodynamical properties of the solutions are investigated by calculating the entropy, the Hawking temperature, the heat capacity, and other physical quantities. The most important result of thermodynamics is that the entropy is not proportional to the area of the black hole. This inanition points out that we must have a constrain on the quadrupole term to get a positive entropy otherwise we get a negative value.

description: We discuss issues relating to the topology of Euclidean de Sitter space. We show that in (2+1) dimensions, the Euclidean continuation of the`causal diamond', i.e the region of spacetime accessible to a timelike observer, is a three-hemisphere. However, when de Sitter entropy is computed in a `stretched horizon' picture, then we argue that the correct Euclidean topology is a solid torus. The solid torus shrinks and degenerates into a three-hemisphere as one goes from the `stretched horizon' to the horizon, giving the Euclidean continuation of the causal diamond. We finally comment on the generalisation of these results to higher dimensions.

Improving the Efficiency of Wind Farm Turbines using External Airfoils
Creators: name: Bader, Shujaut
Publisher: name: University of Massachusetts Amherst
Year: 2017

description: Wind turbine efficiency typically focuses on the shape, orientation, or stiffness of the turbine blades. In this thesis, the focus is instead on using static fixed airfoils in proximity to the wind turbine to control the airflow coming out of the turbine. These control devices have three beneficial effects. (1) They gather air from “higher up” where the air is moving faster on average (and therefore has more kinetic energy in it). (2) They throw the used (and slowed down air) downwards. This means that any turbines in the wind farm behind the lead turbines do not get “stale” air. (3) These control devices provide a large stabilizing lifting force for floating off-shore turbines. In this study, Reynolds-Averaged Navier-Stokes (RANS) simulations of an aligned array of two wind turbines along with various designs of these control devices is studied. The recovery in the velocity at the inlet plane of downstream turbine due to the controlled flow facilitated by these devices is measured with respect to the average streamwise wind velocity at the inlet plane of upstream turbine. A customized numerical solver was written in C++ using Opensource Field Operation And Manipulation (OpenFOAM) to model the turbines as actuator discs with axial induction and to generate an inlet velocity field similar to a turbulent atmospheric boundary layer (ABL). All the design configurations use a streamlined (airfoil shaped) structure, at an angle of attack carefully selected to prevent flow separation depending upon its location around the turbine. For strong wake displacement, the devices are placed in proximity to the upstream wind turbine so as to facilitate a substantial downwash of the faster wind from upper layers of the ABL and at the same time deflect the wake out of the way of the downstream turbine. Also, the pressure coefficient across the upstream turbine augmented with these devices can sometimes become more negative than a bare turbine, which in turn increases the mass flow rate of air passing through it, thereby also increasing the leading turbine’s efficiency slightly.

description: The environment evolved five human senses; through these receptors the majority of us experience life. Or do we? The a vast majority of our daily landscape resides enclosed, shut off from the exterior; separating people from the elements, organizing and distributing the multitude of functions that affect how we live and feel. The mental state of society is poor, the “daily dis-ease” of we wrestle with; stress, emotions, fatigue, exhaustion, disconnection suck the life out of the moments we live to barely even see. These interactions and experiences we encounter in, on, under and around the architectural forms we travel between are often so boring and ordinary we don’t even label them as experience. I challenge architecture can be more. The tangibles (senses) can be invigorated and spaces can be driven and designed by the senses, by the body and by the mind. The creation of unique experiences involves not only the measureable (light, smell, touch, taste & sound etc.) but also immeasurable effects on the body (memory, unity, serenity, etc.) The core of this project aims to cultivate an architecture that provides an array of nurturing and invigorating experiential and exploratory moments harmoniously placed throughout the natural landscape.
Through this reintroduction to experience, the individuals attending the retreat will be engulfed in experiencing the moment and living each breath of sensation. For meditation is the existence in contemplation, relaxation and mental hygiene that provides the platform, the vessel for self-exploration and internal growth. Here the architecture becomes the marbles in the landscape, nestled into the site located in Mountain Park in Holyoke, Ma.

description: Motivated by the dynamics of particles embedded in active gels, both in-vitro and inside the cytoskeleton of living cells, we study an active generalization of the classical trap model. We demonstrate that activity leads to dramatic modifications in the diffusion compared to the thermal case: the mean square displacement becomes sub-diffusive, spreading as a power-law in time, when the trap depth distribution is a Gaussian and is slower than any power-law when it is drawn from an exponential distribution. The results are derived for a simple, exactly solvable, case of harmonic traps. We then argue that the results are robust for more realistic trap shapes when the activity is strong.
Electroless Deposition & Electroplating of Nickel on Chromium-Nickel Carbide Powder

description: Engineered components can gain desirable properties when coated with surface materials. Wear-resistant coatings can improve the performance of contacting surfaces and allow for an extended life of the parts. Hard chromium has been the plating material of choice for certain wear and corrosion- resistant coatings because of its desirable combination of chemical resistance, adhesion, and mechanical properties. However, hexavalent chromium, a component of the process for applying hard chromium coatings, has been recognized by the EPA as having hazardous health and environmental impacts. Existing and planned environmental regulations restricts the use of process chemicals containing hexavalent chromium ions. This substantiates a need to develop an environmental friendly process for alternative coatings.
Praxair has reported that Cr-Ni-C particles have a better corrosion resistance than current chromium carbide and nickel chromium powders. Today, Cr-Ni-C provides great qualities for flame spray and does not contain the toxic compounds used to deposit hard chromium, but is not compatible with application by cold spray.
The purpose of this thesis project is to compare two processes for plating metal powder, chromium nickel carbide (Cr-Ni-C, CRC-410-1 from Praxair), with nickel. The particles were encapsulated using three different methods: one electroplating method previously used on particles, and two electroless plating processes using different solutions.
The Cr-Ni-C particles were successfully encapsulated with Ni by one of the electroless deposition methods. The electrolytic deposition experiments did not yield the uniformity of coating without agglomeration that is being attained in industrial practice today. Further research on this method is recommended, due to the material operational cost in an industrial setting that is projected to be over 200 times cheaper than electroless deposition method. In the meantime, it should be possible to produce enough coated powder by electroless deposition to validate the utility of this coated powder in depositing wear- and corrosion-resistant coatings of Cr-Ni-C by cold spray.
ORACLE GUIDED INCREMENTAL SAT SOLVING TO REVERSE ENGINEER CAMOUFLAGED CIRCUITS

description: This study comprises two tasks. The ﬁrst is to implement gate-level circuit camouﬂage techniques. The second is to implement the Oracle-guided incremental de-camouﬂage algorithm and apply it to the camouﬂaged designs.
The circuit camouﬂage algorithms are implemented in Python, and the Oracle- guided incremental de-camouﬂage algorithm is implemented in C++. During this study, I evaluate the Oracle-guided de-camouﬂage tool (Solver, in short) performance by de-obfuscating the ISCAS-85 combinational benchmarks, which are camouﬂaged by the camouﬂage algorithms. The results show that Solver is able to eﬃciently de-obfuscate the ISCAS-85 benchmarks regardless of camouﬂaging style, and is able to do so 10.5x faster than the best existing approaches. And, based on Solver, this study also measures the de-obfuscation runtime for each camouﬂage style.

Productivity Analysis

description: The productivity of improved pastures in Australia's southeastern grazing regions is now believed to be in a state of long-te1m decline. As yet, there is little economic evidence to support this perception. The analysis reported in this paper seeks to examine improved pasture productivity change from an economic standpoint in a major Australian grazing area. The analysis rests on the central proposition that the productivity of the livestock enterprises is a direct reflection of pasture productivity. Using both index number and econometric methods, the results indicate that while the annual growth in livestock and hence, improved pasture productivity has been positive over the period, there has been a significant decline in legume pasture productivity. Because these pastures comprise the bulk of improved pastures, the livestock productivity of all improved pastures has declined in recent years. In contrast, the growth in livestock productivity from the perennial grass pastures continues to be high. The main reasons for legume pasture livestock productivity decline appear to be various important biological problems and the long-term decline in the farmers' terms-of-trade.

description: Thesis Abstract:Within an ageing population, there is continued need for timely and accurate dementia diagnosis, and provision of support for family members who increasingly provide informal care. Understanding of care recipients’ cognitive profile, and greater knowledge of the experience of caregiver burden, may facilitate the provision of such support.Literature Review:Characteristics of carer burden reported by caregivers of persons diagnosed with Alzheimer’s Disease, Vascular dementia, Dementia with Lewy Bodies, and Frontotemporal dementias were reviewed. An integrative approach was taken to combine both quantitative and qualitative findings from 15 published papers. Inconclusive findings are presented. Further research incorporating a mixed-methods design and matched participant groups would enable greater understanding.Research Report:An initial exploration of the reliability and validity of the Short Parallel Assessments of Neuropsychological Status (SPANS) was undertaken within a sample of healthy and functionally able adults over the age of 65 years. The psychometric properties of the SPANS with working-age adults has been previously documented (Burgess, 2014), and acted as a source of comparison for current findings. Internal reliability was explored, in addition to confirmation of good alternate version reliability. Convergent validity was explored in relation to the Addenbrooke’s Cognitive Assessment (ACE-III), and indicated that the SPANS likely performs at least to an equivalent level, with potential to offer additional clinical benefits beyond those conveyed by the ACE-III. Findings were limited by insufficient statistical power and lack of variance within the sample, leading to the recommendation of further research to confirm and expand upon current findings.

description: Contribution of the gluon distribution in the nucleon to the cross section for the pion diffractive dissociation into two jets has been calculated recently. In addition, we present here calculation of contribution of the quark distributions to this process. It is expected usually that the quark contributions are much smaller than the gluon one at high energies. We show that, under the conditions of the E791 experiment, the quark contributions are as significant as the gluon one, so that the total cross section exceeds several times those with only gluon contribution. Nevertheless, the distribution of jets in longitudinal momentum fractions does not change significantly and remains qualitatively the same. We compare our results with the data from the E791 experiment.

description: Functions for total wheat production, the major agricultural crop of Gaziantep, Sanliurfa, Diyarbakir, and Mardin provinces in Southeastern Anatolian Project (SAP) region in Turkey were developed by using annual data for the 1963-1989 period. Regression analyses were carried out on the multiple-linear, quadratic, and Cobb-Douglas functional forms of total wheat production in the region effected by cultivation area, fertilizer usage, and rainfall. From the economical theories' point of view the model revealed good insight. The models were statistically significant at the 95% confidence level. Irrigation is valued quite substantially. Output elasticities of inputs are less than 1 and function coefficient is elastic. Thus input employment can be increased to increase wheat production. Further research based on factor analysis is recommended.

description: While various excitonic insulators have been studied in the literature, due to the perceived too-small spin splitting, spin-triplet excitonic insulator is rare. In two-dimensional systems such as a graphone, however, it is possible, as revealed by first-principles calculations coupled with Bethe-Salpeter equation. The critical temperature, given by an effective Hamiltonian, is 11.5 K. While detecting excitonic insulators is still a daunting challenge, the condensation of triplet excitons will result in spin superfluidity, which can be directly measured by a transport experiment. Nonlocal dielectric screening also leads to an unexpected phenomenon, namely, an indirect-to-direct transition crossover between single-particle band and exciton dispersion in graphone, which offers yet another test by experiment.
