description: GR 290 (M 33 V0532 = Romano's Star) is a unique variable star in the M33 galaxy, which simultaneously displays variability typical for luminous blue variable (LBV) stars and physical parameters typical for nitrogen-rich Wolf-Rayet (WR) stars (WN). As of now, GR 290 is the first object which is confidently classified as a post-LBV star. In this paper, we outline the main results achieved from extensive photometric and spectroscopic observations of the star: the structure and chemical composition of its wind and its evolution over time, the systematic increase of the bolometric luminosity during the light maxima, the circumstellar environment. These results show that the current state of Romano's Star constitutes a fundamental link in the evolutionary path of very massive stars.

description: We study assortative mixing in networks, the tendency for vertices in networks to be connected to other vertices that are like (or unlike) them in some way. We consider mixing according to discrete characteristics such as language or race in social networks and scalar characteristics such as age. As a special example of the latter we consider mixing according to vertex degree, i.e., according to the number of connections vertices have to other vertices: do gregarious people tend to associate with other gregarious people? We propose a number of measures of assortative mixing appropriate to the various mixing types, and apply them to a variety of real-world networks, showing that assortative mixing is a pervasive phenomenon found in many networks. We also propose several models of assortatively mixed networks, both analytic ones based on generating function methods, and numerical ones based on Monte Carlo graph generation techniques. We use these models to probe the properties of networks as their level of assortativity is varied. In the particular case of mixing by degree, we find strong variation with assortativity in the connectivity of the network and in the resilience of the network to the removal of vertices.

description: We study a two-terminal Josephson junction with conventional superconductors and a normal region with Rashba spin-orbit interaction, characterized by two Aharonov-Casher (AC) fluxes. When the superconducting phase difference equals $π$, the Andreev subgap spectrum may host zero-energy Weyl singularities associated with a vanishing normal-state reflection eigenvalue. With one of the AC fluxes playing the role of a quasimomentum, the junction can be viewed as an artificial one-dimensional chiral topological insulator. Its topological phase can be tuned by crossing a Weyl singularity by means of varying the remaining AC flux. By associating an additional component of the quasimomentum with the superconducting phase difference, an artificial Chern insulator is realized.

Computing syzygies in finite dimension using fast linear algebra

description: We consider the computation of syzygies of multivariate polynomials in a finite-dimensional setting: for a $\mathbb{K}[X_1,\dots,X_r]$-module $\mathcal{M}$ of finite dimension $D$ as a $\mathbb{K}$-vector space, and given elements $f_1,\dots,f_m$ in $\mathcal{M}$, the problem is to compute syzygies between the $f_i$'s, that is, polynomials $(p_1,\dots,p_m)$ in $\mathbb{K}[X_1,\dots,X_r]^m$ such that $p_1 f_1 + \dots + p_m f_m = 0$ in $\mathcal{M}$. Assuming that the multiplication matrices of the $r$ variables with respect to some basis of $\mathcal{M}$ are known, we give an algorithm which computes the reduced Gröbner basis of the module of these syzygies, for any monomial order, using $O(m D^{ω-1} + r D^ω\log(D))$ operations in the base field $\mathbb{K}$, where $ω$ is the exponent of matrix multiplication. Furthermore, assuming that $\mathcal{M}$ is itself given as $\mathcal{M} = \mathbb{K}[X_1,\dots,X_r]^n/\mathcal{N}$, under some assumptions on $\mathcal{N}$ we show that these multiplication matrices can be computed from a Gröbner basis of $\mathcal{N}$ within the same complexity bound. In particular, taking $n=1$, $m=1$ and $f_1=1$ in $\mathcal{M}$, this yields a change of monomial order algorithm along the lines of the FGLM algorithm with a complexity bound which is sub-cubic in $D$.

description: Europium-doped nanocrystals constitute a promising material for a scalable future quantum computing platform. Long-lived nuclear spin states could serve as qubits addressed via coherent optical transitions. In order to realize an efficient spin-photon interface, we couple the emission from a single nanoparticle to a fiber-based microcavity under cryogenic conditions. The spatial and spectral tunability of the cavity permits us to place individual nanoparticles in the cavity, to measure the inhomogeneous linewidth of the ions, and to show a multi-modal Purcell-enhancement of two transition in Eu$^{\text{3+}}$. A halving of the free-space lifetime to 1.0 ms is observed, corresponding to a 140-fold enhancement of the respective transition. Furthermore, we observe a narrow optical linewidth of 3.3 MHz for a few-ion ensemble in the center of the inhomogeneous line. The results represent an important step towards the efficient readout of single Eu$^{\text{3+}}$ ions, a key requirement for the realization of single-ion-level quantum processing nodes in the solid state.

description: The quasi-unit cell picture describes the atomic structure of quasicrystals in terms of a single, repeating cluster which overlaps neighbors according to specific overlap rules. In this paper, we discuss the precise relationship between a general atomic decoration in the quasi-unit cell picture atomic decorations in the Penrose tiling and in related tiling pictures. Using these relations, we obtain a simple, practical method for determining the density, stoichiometry and symmetry of a quasicrystal based on the atomic decoration of the quasi-unit cell taking proper account of the sharing of atoms between clusters.

description: We describe the construction and calibration of a multi-channel liquid time projection chamber filled with Tetramethylsilane (TMS). Its charge readout system consists of 8 wires each in the $X$ and $Y$ directions. The chamber is also equipped with a Cherenkov light readout system consisting of a 5-inch photomultiplier tube (PMT) coupled to the liquid volume through a viewport. The energy scale of the detector is calibrated using positron-electron pairs produced by 4.4 MeV gamma rays emitted from an AmBe source, using an external trigger on the positron annihilation gammas. The external trigger is then reconfigured to tag cosmic ray muons passing through the active TMS volume, which are used to measure the stopping power in TMS and the electron lifetime in the detector. We find a most-probable energy loss from minimum ionising particles (MIPs) of $Δ_p/ds$ = (0.60$\pm$0.01) MeV/cm. We also derive an electron lifetime of 43$^{+680}_{-21}~μ$s by measuring the most-probable energy loss as a function of drift time. For both fast electron and muon signals, the PMT detects prompt Cherenkov light, demonstrating the possibility of random triggering. The room-temperature organic target medium, together with the self-triggering capabilities and long electron lifetimes reported in this work, make this an attractive technology to further explore for rare event detectors or other applications in the area of radiation measurements.

description: My research examines the interconnected histories of urbanism and urban development in port cities across South and Southeast Asia. Chapter one examines the effects of the third plague pandemic on the quotidian livelihoods and the built environments of the urban poor across Bombay, Hong Kong, and Singapore. Considering corporeal measures to inspect the bodies and homes of the urban poor and measures to introduce urban ‘improvement’ schemes, this chapter argues that plague sparked a sustained interest in the urban conditions of the poor across British South and Southeast Asia. Chapter two considers the works of the Bombay Improvement Trust, Rangoon Development Trust, and Singapore Improvement Trust through the early decades of the twentieth century and analyses how an imperial urbanism based on a ‘Bombay model’ translated to Singapore and other port cities across the Indian Ocean world. Chapter three considers the consequences of the second wave of ‘indirect’ attacks on urban slums on an evolving imperial urbanism in Bombay, Rangoon, and Singapore. While previous chapters examined the emergence of an imperial urbanism centred on Bombay’s example, chapter four considers the extent to which Bombay remained central to this urbanism during the late 1930s and Second World War. Analysing the divergent consequences of patterns of urban growth in Bombay, Hong Kong, and Singapore throughout the late-1930s, this chapter considers late-colonial efforts to house the urban poor as well as the extent to which the war recast the post-war housing situation. Chapter five contextualises post-war rhetoric of economic and urban development in Hong Kong and Singapore within narratives of pre-war urban ‘improvement’. In connecting pre-war and post-war approaches to accommodating the urban poor, the final chapter considers the reorientation of earlier circulations of knowledge around urban poverty in port cities and its implications for emerging post-colonial regional, national and urban identities.

description: This study explored consumers‟ use and understanding of food label information and the effect on their purchasing decision in the Kumasi Metropolis. It also investigated the association between socio-demographic factors and the use of food label, the understanding of the information read as well as the type of information sought. The study surveyed 250 consumers who were conveniently selected from five different sub-metros in the metropolis. Questionnaires were formulated to sample data and information from consumers on their use and understanding of Food Label Information. Results suggested that the sample was gender sensitive (57.6% male) with a modal aged group between 15-30 years (60.8%) who had never been married (54.0%), with a greater number who had tertiary education (36.4%) and earning low income between GH¢50- 499 (61.6%). About 79.6% (n=199) of the respondents, recounted accessing food label information before purchase and they read the information occasionally (29.6%) during initial purchase (37.2%). Majority of the respondent said advertisement (31.6%) and price (31.2%) other than food label (10.0%) were the central stimuli to purchase a canned food product. Highly-educated, male consumers (xsuperscipt2=17.602,df=, p=0.007, ) were those more likely to use various types of food label information than others. A positive relationship was observed between male, youthful (31-45) consumers and consumer who were never been married and their use and understanding of food label information.

description: Farmers’ Empowerment has become an important part of the development agenda in the recent years. This study identified and analyzed the poverty status in terms of incidence, depth and severity among arable crop farmers in Osun State and compared the socio-economic characteristics of beneficiaries and non-beneficiaries of Farmers Empowerment Programme (FEP) in Osun State, Nigeria. The study made use of pre-tested and validated structured questionnaire. A multi-stage sampling procedure was used to select 240 respondents. Data collected were analyzed using a combination of descriptive statistics, t-test of difference of two means and p-alpha measures of poverty. The result of poverty incidence, depth, and severity among respondents indicated that poverty incidence was lower among the FEP beneficiaries (0.42) than the non beneficiaries (0.58). Poverty gap index was also lower among the beneficiaries of FEP (0.19) than with the non-beneficiaries (0.46). The severity of poverty was mild (0.13) among the FEP beneficiaries while it was severe among non-beneficiaries (0.43). The Lorenz curve revealed that 22.5 percent of the respondents control 50 per cent of the resources available indicating an apparent inequality in income distribution. A significant difference exists between the age (p<0.05), household size (p < 0.05), membership of cooperative societies (p < 0.05), land ownership (p < 0.05) and income (p < 0.05) of beneficiaries and non-beneficiaries of FEP, respectively. In conclusion, the FEP has alleviated poverty among the participants in the study area. The level of education, household size and farmers’ experience are the key determinants in alleviating poverty among the participating arable crop farmers in the FEP in Osun State.

description: A model is presented to describe the recently proposed experiment (J. Raimond, M. Brune and S. Haroche Phys. Rev. Lett {\bf 79}, 1964 (1997)) where a mesoscopic superposition of radiation states is prepared in a high-Q cavity which is coupled to a similar resonator. The dynamical coherence loss of such state in the absence of dissipation is reversible and can in principle be observed. We show how this picture is modified due to the presence of the environmental couplings. Analytical expressions for the experimental conditional probabilities and the linear entropy are given. We conclude that the phenomenon can still be observed provided the ratio between the damping constant and the inter-cavities coupling does not exceed about a few percent. This observation is favored for superpositions of states with large overlap.

description: Integration of organic and inorganic fertilizers is inevitable to sustain intensive agricultural production; however, assessment of combination of organic and inorganic fertilizers on soil phosphorus (P) fractions is yet to be understood. This study aims to investigate availability, distribution, and fractions of soil P as influenced by long-term fertilization under soybean-based cropping systems in Vertisol. Soil samples were collected during 2021 from a 17-year-old field experiment with six treatments viz., T1: 100% Organic, T2: 75% Organic + 25% Innovative approach, T3: 50% Organic + 50% Inorganic, T4: 75% Organic + 25% Inorganic, T5: 100% Inorganic, and T6: State recommendation under soybean-wheat, soybean-mustard, and soybean-chickpea cropping systems at two soil depths after wheat, mustard, and chickpea, and examined for 0.5 M NaHCO3-P, total P, inorganic P, and different P fractions namely, saloid-P (1 M NH4Cl), aluminium-P (0.5 M NH4F), iron-P (0.1 M NaOH), calcium-P (0.25 M H2SO4), and reductant soluble-P (0.3 M Na3C3H6O7 + 1 M NaHCO3 + Na2S2O3). Results demonstrates that continuous fertilization using organic, inorganic, and their combination influences soil P dynamics. Soybean-chickpea system was found better in sustaining P availability. Higher NaHCO3-P was observed under 50% organic + 50% inorganic plot. Inorganic fertilizer dominated soil P accumulation as observed from higher inorganic fractions, and total P. Addition of organic manure could contribute to solubilization of fixed-P fractions and renders plant available form. It can be concluded that fertilization with organic manures and inorganic fertilizer should be followed so that 25–50% costly P-fertilizers could be saved for crop production under soybean-based cropping systems in Vertisols.

description: The spontaneous decay rates of an excited atom placed near a dielectric cylinder are investigated. A special attention is paid to the case when the cylinder radius is small in comparison with radiation wavelength (nanofiber or photonic wire). In this case, the analytical expressions of the transition rates for different orientations of dipole are derived. It is shown that the main contribution to decay rates is due to quasistatic interaction of atom dipole momentum with nanofiber and the contributions of guided modes are exponentially small. On the contrary, in the case when the radius of fiber is only slightly less than radiation wavelength, the influence of guided modes can be substantial. The results obtained are compared with the case of dielectric nanospheroid and ideally conducting wire.

description: In spite of the substantial contribution of floriculture to the Nigerian economy, there is still a low level of awareness on the potential of the horticultural subsector of the Nigerian agricultural sector to generate employment and reduce poverty. This study therefore carried out an assessment of the economics of floricultural plants production in Kwara State, Nigeria. The study specifically estimated the returns to farmer’s labour and management. It also assessed the determinants of returns to floricultural plant production in the state. Data used for the study were collected from the forty one registered floricultural plant producers in the study area using structured questionnaire. The farm budget and regression analyses were used for data analyses. The study revealed that returns to farmer’s labour and management was N174, 974.7/ha on the average. Use of manure, labour, farm size, experience, educational level and age of the farmer were found to have significant influence on farmer’s revenue. Inadequate capital to expand the scale of production was identified as the major constraints to floricultural plant production in the study area. The study therefore recommends that farmers be supported by making credit facilities available to them and that people be enlightened on the profitability potential of the enterprise.

description: The Josephson current between an s-wave and a spin-triplet superconductor Sr$_2$RuO$_4$ (SRO) is studied theoretically. In spin-singlet / spin-triplet superconductor junctions, there is no Josephson current proportional to $\sin ϕ$ in the absence of the spin-flip scattering near junction interfaces, where $ϕ$ is a phase-difference across junctions. Thus a dominant term of the Josephson current is proportional to $\sin 2ϕ$ . The spin-orbit scattering at the interfaces gives rise to the Josephson current proportional to $\cosϕ$, which is a direct consequence of the chiral paring symmetry in SRO.

description: The Standard Model has granted exquisite power to predict the behaviour of high-energy particle collisions. It is not, however, without conceptual and empirical weaknesses. Several theories have been proposed which aim to resolve these difficulties. This thesis describes searches for two such theories: models of extra spatial dimensions, and supersymmetry. The Large Hadron Collider has extended the frontiers of energy and intensity in particle physics. In 2015, the LHC resumed proton–proton collisions at a centre-of-mass energy of 13 TeV. This increase over previous operation grants an enhancement in sensitivity to many processes beyond those of the Standard Model. Extra-dimensional theories address the hierarchical nature of the Standard Model. The lowered fundamental scale of gravity in these models allows a rich phenomenology at energies which may be accessible to the LHC. Some models predict the formation of microscopic black holes, which are the target of an analysis of collisions recorded by the ATLAS detector in 2015. No significant deviations from Standard Model predictions were observed. The constraints inferred on the parameters of the model are a significant advance on previous results. Lepton flavour is conserved in the Standard Model. This is not the result of a known fundamental symmetry, however. The latter part of this thesis proposes a search examining asymmetries of charge and flavour in the eμ final state. Models of supersymmetry with an R-parity-violating $\lambda'_{231}$ coupling are taken as motivation. The strategy is developed using collision data recorded by ATLAS in 2015 and 2016, and the most significant biasing effects are addressed.

description: Participatory rural development has evolved in the past 60 years as a development process and discourse that should encapsulate a wide range of views, voices and stakeholder contributions. How has this approach been followed in Nigeria‟s rural development practice? This paper reviews the practices and challenges of participatory rural development in Nigeria from a historical perspective emphasizing on the colonial system and post-colonial military and civilian governance. The paper observes that participatory development has not been practiced in the real sense of the concept in rural development in Nigeria. While highly centralized and top-down exploitative rural development practice dominated the colonial system up to the period of post-independence military dictatorship, not much significant difference have been observed within the current civilian democratic experiment. The paper argues that while long years of military rule in Nigeria have made it impossible for the development of effective institutional arrangements that could sustain true participatory democratic culture, a lack of citizens‟ capacity to participate in development intended for their benefit has posed the greatest challenge in achieving sustainable participatory rural development.

description: In this work we will introduce the A-V-A formulation based iterative algorithm method (IAM) for simulating the magnetization current of high temperature superconductors. This new method embedded in ANSYS can simulate the critical state model by forcing the trapped current density to the critical current density Jc for all meshed superconducting elements after each iterative load step, as well as simulate the flux creep model by updating the E-J power law based resistivity values. The simulation results of a disk-shaped ReBCO bulk during zero field cooling (ZFC) or field cooling (FC) magnetization agree well with the simulation results from using the H-formulation in COMSOL. The computation time is shortened by using the A-V formulation in superconductor areas and the A-formulation in non-superconductor areas. This iterative method is further proved friendly for adding ferromagnetic materials into the FEA model or taking into account the magnetic field-dependent or mechanical strain-related critical current density of the superconductors. The influence factors for the magnetization simulation, including the specified iterative load steps, the initial resistivity, the ramping time and the updating coefficient, are discussed in detail. The A-V-A formulation based IAM, implemented in ANSYS, shows its unique advantages in adjustable computation time, multi-frame restart analysis and easy-convergence.

description: Identifying the drivers of Arctic climate variability is essential for understanding the recent rapid changes in local climate and determining the mechanisms that cause them. Remote tropical sea surface temperatures (SST) have been identified in previous studies as having contributed to the recent positive trends in surface temperature and geopotential height at 200 hPa over north Canada and Greenland (1979-2012) through poleward propagating Rossby waves. However, the source and direction of wave propagation on to north Canada and Greenland (NCG) differs across climate datasets indicating that there are still uncertainties surrounding the mechanisms for how the tropics influence the NCG climate. This thesis aims to further investigate the robustness of the trends over NCG and understand how circulation in this region responds to imposed tropical SST perturbations. The eddy 200 hPa geopotential height (Z200) trends over NCG are assessed in a number of different datasets and compared to the response of eddy Z200 over NCG to imposed tropical SST perturbations in a number of sensitivity studies using the HadGEM3 atmosphere-only model. These model experiments are forced with observed differences in SSTs from the beginning and end of the satellite record (1979-1988 and 2003-2012), with spatial perturbations for [i] the entire tropics, [ii] global SSTs, [iii] the tropical Pacific only, [iv] the tropical Atlantic SST only, [v] the tropical Indian Ocean only. The positive spatial trends of eddy Z200 over NCG from ERA-Interim reanalysis is largely captured in ensemble means of two available climate datasets, UPSCALE and AMIP, indicating that this is a robust climate pattern, however, these trends appear to be stronger in the latter part of the record specifically over the UPSCALE period (1985 to 2011). The model sensitivity studies show that a negative eddy Z200 anomaly over NCG was found in response to all imposed tropical SST perturbations (2003-2012) relative to a background state (1979-1988). This was due a stationary trough over the region that was able to intensify in response to a lack of a strong anomalous wave forcing from changes in mid-tropospheric temperature and zonal winds. The forcing from the tropical Atlantic, relative to the other tropical ocean basins, resulted in the largest eddy Z200 response over NCG, indicating its dominance in forcing the large scale tropical signal. The influence of extratropical SST perturbations relative to tropical SST perturbations were also investigated and it was demonstrated that this negative anomaly is largely driven by the change in tropical sea surface temperatures.

biomarkers of recency

description: Monitoring the epidemic of Human Immunodeficiency Virus (HIV) infection plays a vital role in tracking the leading edge of HIV transmission and designing intervention programs both at individual and population level. At individual level, it is imperative to identify newly infected individuals to reduce onwards transmission. At population level, knowledge on the HIV incidence is essential to monitor the spread of the epidemic and plan/evaluate HIV prevention programs. This dissertation will examine the way in which biomarker data can be used to monitor the HIV epidemic. There are two primary aims of this thesis: a) to investigate the use of biomarkers in quantifying the recency of HIV infection at individual level and b) to estimate quantities such as mean window period and testing rate that are the building blocks for estimating HIV incidence at population level. We apply and further develop existing statistical methods to answer the research questions of interest. At individual level, we investigate the use of one or more biomarkers to quantify the recency of HIV infection. We propose a novel approach to make probabilistic statements on the recency of HIV infection by combining the knowledge on the growth of such biomarkers with observations from a newly diagnosed individual. Univariate and bivariate non-linear mixed-effects models are implemented in a fully Bayesian framework. A simulation study is conducted to investigate the biomarkers’ features that affect the accuracy of the estimation of recency. The research findings suggest that rapidly evolving biomarkers of antibody response, such as LAg Avidity, provide reliable estimates of the probability of recency. The proposed methods are applied to a panel of individuals for whom information on various biomarkers is given along with an estimated date of detectable infection. At population level, we focus on estimating two fundamental ingredients, the mean window period and the HIV testing rate, required for estimating HIV incidence using biomarker data. We compare commonly used statistical methods and explore the use of multi-state models in estimating the mean window period of the fourth generation Architect Avidity. We further investigate the factors that are associated with the probability of having an HIV test and the HIV testing rate using surveillance data. Logistic and count regression models using the Generalized Estimating Equations (GEE) approach are employed to make inference at population level about the probability of testing and HIV testing rate respectively.

description: We provide a review of both new experimental and theoretical developments in the Casimir effect. The Casimir effect results from the alteration by the boundaries of the zero-point electromagnetic energy. Unique to the Casimir force is its strong dependence on shape, switching from attractive to repulsive as function of the size, geometry and topology of the boundary. Thus the Casimir force is a direct manifestation of the boundary dependence of quantum vacuum. We discuss in depth the general structure of the infinities in the field theory which are removed by a combination of zeta-functional regularization and heat kernel expansion. Different representations for the regularized vacuum energy are given. The Casimir energies and forces in a number of configurations of interest to applications are calculated. We stress the development of the Casimir force for real media including effects of nonzero temperature, finite conductivity of the boundary metal and surface roughness. Also the combined effect of these important factors is investigated in detail on the basis of condensed matter physics and quantum field theory at nonzero temperature. The experiments on measuring the Casimir force are also reviewed, starting first with the older measurements and finishing with a detailed presentation of modern precision experiments. The latter are accurately compared with the theoretical results for real media. At the end of the review we provide the most recent constraints on the corrections to Newtonian gravitational law and other hypothetical long-range interactions at submillimeter range obtained from the Casimir force measurements.

description: One of the major open questions in particle physics is the issue of the neutrino mass ordering (NMO). The current data of the two long-baseline experiments NO$ν$A and T2K, interpreted in the standard 3-flavor scenario, provide a $\sim2.4σ$ indication in favor of the normal neutrino mass ordering. We show that such an indication is completely washed out if one assumes the existence of neutral-current non-standard interactions (NSI) of the flavor changing type involving the $e-τ$ flavors. This implies that the claim for a discovery of the NMO will require a careful consideration of the impact of hypothetical NSI.

description: In The Ring and the Book, Browning presents a spectrum of twelve dramatic monologues to tell a complicated murder story in 17th century Rome. Browning delves into the environs of 17th century Italy in creating the backdrop for the narrative in Books Two, Three, and Four, supplying these voices to provide historical and social context to the private matter of domestic violence. Understanding the function of this leading triad necessitates investigation into the relation of community and public space to the act of uxoricide. The counter-position of "Half-Rome" in Book II and "The Other Half-Rome" in Book III produces an artificial representation of the dialogue which occurs in the public sphere. This thesis argues that Browning creates the Roman public based on a perspective of history derived partly from British history prior to Browning's era. In assembling the three books; "Half-Rome," "The Other Half-Rome," and "Tertium Quid;" Browning constructs a representation of the Roman populace. This thesis reads the debate in the Roman community from the perspective of 20th century theories of the public sphere. Habennas' theory of the "public discourse about private life" used to describe public discussion in the 16th and 17th centuries will provide new insight into Browning's historical perspective. Specifically, Browning's presentation of public dialectic reviews mid-Victorian concerns over the public rhetoric by anonymous authors in the periodical press. In addition, this analysis extends knowledge concerning the relationship between Victorian writers and their historical predecessors.
