description: We present observations that were carried out with the Two HUndred Micron PhotometER (THUMPER) mounted on the James Clerk Maxwell Telescope (JCMT) in Hawaii, at a wavelength of 200 um (frequency 1.5 THz). The observations utilise a small atmospheric window that opens up at this wavelength under very dry conditions at high-altitude observing sites. The atmosphere was calibrated using the sky-dipping method and a relation was established between the optical depth, tau, at 1.5 THz and that at 225 GHz: tau_1.5THz = (95 +/- 10)*tau_225GHz. Mars and Jupiter were mapped from the ground at this wavelength for the first time, and the system characteristics measured. A noise equivalent flux density (NEFD) of ~65 +/- 10 Jy (1 sigma 1 second) was measured for the THUMPER-JCMT combination, consistent with predictions based upon our laboratory measurements. The main-beam resolution of 14 arcsec was confirmed and an extended error-beam detected at roughly two-thirds of the magnitude of the main beam. Measurements of the Sun allow us to estimate that the fraction of the power in the main beam is ~15%, consistent with predictions based on modelling the dish surface accuracy. It is therefore shown that the sky over Mauna Kea is suitable for astronomy at this wavelength under the best conditions. However, higher or drier sites should have a larger number of useable nights per year.

description: We have investigated the hydrogen-bonded structures in liquid methanol and a 7:3 mole fraction aqueous solution using classical Molecular Dynamics simulations at 298K and ambient pressure. We find that, in contrast to recent predictions from X-ray emission studies, the hydrogen-bonded structure in liquid methanol is dominated by chain and small ring structures. In the methanol-rich solution, we find evidence of micro-immiscibility, supporting recent conclusions derived from neutron diffraction data.

Subjects: Linked Data, epidemiology, RDF, COVID-19, COVID-19 severity risk factors

description: This thesis aims to provide practical insights into the Linked Data approach to epidemiology. The insights are based on the preliminary results of a real-world study at the Pediatric Hospital of the Medical University of Warsaw which was concerned with investigating various medical and social risk factors on COVID-19 severity in children and SARS-CoV-2 spread dynamics. The thesis delivers results regarding the influence of various comorbidities on COVID-19 severity, based on a case of 90 patients of the Hospital, and establishes that metabolic disorders had a statistically significant influence on the hospitalization length in the observed sample (alpha = 0.05). It discusses the role of Linked Data in obtaining that result and presents ways to reuse that approach to enable similar studies. An overview of the theoretical framework for the paradigm is presented and its practical implications are discussed. Additionally, the thesis provides a technical report of the implemented data processing pipeline.

description: The accurate modeling of the dielectric properties of water is crucial for many applications in physics, computational chemistry and molecular biology. This becomes possible in the framework of nonlocal electrostatics, for which we propose a novel formulation allowing for numerical solutions for the nontrivial molecular geometries arising in the applications mentioned before. Our approach is based on the introduction of a secondary field, $ψ$, which acts as the potential for the rotation free part of the dielectric displacement field ${\bf D}$. For many relevant models, the dielectric function of the medium can be expressed as the Green's function of a local differential operator. In this case, the resulting coupled Poisson (-Boltzmann) equations for $ψ$ and the electrostatic potential $ϕ$ reduce to a system of coupled PDEs. The approach is illustrated by its application to simple geometries.

description: In recent years, novel two-dimensional materials such as graphene, bismuthene and transition-metal dichalcogenides have attracted considerable interest due to their unique physical properties. A range of physical effects can be transferred to the realms of photonics by creating artificial photonic lattices emulating these two-dimensional materials. Here, exciton-polaritons in semiconductor microcavities offer an exciting opportunity to study a part-light, part-matter quantum fluid of light in a complex lattice potential. In this paper, we study exciton-polaritons in a two-dimensional Lieb lattice of buried optical traps. The $S$ and $P_{xy}$ photonic orbitals of such a Lieb lattice give rise to the formation of two flatbands which are of greatest interest for the distortion-free storage of compact localized states. By using a well controlled etch-and-overgrowth technique, we manage to control the trapping as well as the site couplings with great precision. This allows us to spectroscopically monitor the flatness of the flatbands across the full Brillouin zone. Furthermore, we demonstrate experimentally that these flatbands can be directly populated by condensation under non-resonant laser excitation. Finally, using this advanced device approach we demonstrate resonant and deterministic excitation of flatband modes in transmission geometry. Our findings establish the exciton-polariton systems as a highly controllable, optical many-body system to study flatband effects and for distortion-free storage of compact localized states.

description: The color-changing dress is a 2015 Internet phenomenon in which the colors in a picture of a dress are reported as blue-black by some observers and white-gold by others. The standard explanation is that observers make different inferences about the lighting (is the dress in shadow or bright yellow light?); based on these inferences, observers make a best guess about the reflectance of the dress. The assumption underlying this explanation is that reflectance is the key to color constancy because reflectance alone remains invariant under changes in lighting conditions. Here, we demonstrate an alternative type of invariance across illumination conditions: An object that appears to vary in color under blue, white, or yellow illumination does not change color in the high spatial frequency region. A first approximation to color constancy can therefore be accomplished by a high-pass filter that retains enough low spatial frequency content so as to not to completely desaturate the object. We demonstrate the implications of this idea on the Rubik’s cube illusion; on a shirt placed under white, yellow, and blue illuminants; and on spatially filtered images of the dress. We hypothesize that observer perceptions of the dress’s color vary because of individual differences in how the visual system extracts high and low spatial frequency color content from the environment, and we demonstrate cross-group differences in average sensitivity to low spatial frequency patterns.

description: We simulate the ionization environment of z ~ 20 luminous objects formed within the framework of the current CDM cosmology and compute their UV escape fraction. These objects are likely single very massive stars that are copious UV emitters. We present analytical estimates as well as one--dimensional radiation hydrodynamical calculations of the evolution of these first HII regions in the universe. The initially D--type ionization front evolves to become R--type within $\lesssim 10^5$ yrs at a distance $\sim1$ pc. This ionization front then completely overruns the halo, accelerating an expanding shell of gas outward to velocities in excess of 30 km s$^{-1}$, about ten times the escape velocity of the confining dark matter halo. We find that the evolution of the HII region depends only weakly on the assumed stellar ionizing luminosities. Consequently, most of the gas surrounding the first stars will leave the dark halo whether or not the stars produce supernovae. If they form the first massive seed black holes these are unlikely to accrete within a Hubble time after they formed until they are incorporated into larger dark matter halos that contain more gas. Because these I--fronts exit the halo on timescales much shorter than the stars' main sequence lifetimes their host halos have UV escape fractions of $\gtrsim 0.95$, fixing an important parameter for theoretical studies of cosmological hydrogen reionization.

description: Mo-substituted triple perovskite superconducting samples with the stoichiometric composition La(1.5)Nd(0.5)Ca(1)Ba(2)[Cu(1-x)Mo(x)](5)O(z), [LNCBCuMO] with x = 0.00, 0.01, 0.03, 0.05 and 0.10, have been investigated using X-ray diffraction, electrical resistivity, magnetic susceptibility, magnetization and oxygen content measurements. The observed reduction in Tc with increasing Mo content (x) in LNCBCuMO, can be attributed to the decrease in hole concentration. Magnetization measurements as a function of temperature and field (H), exhibit an M-H hysteresis loop, which indicates moderate flux pinning, which can be attributed to the pinning centers created by Mo substitution at Cu sites. The critical current density, Jc, deduced from the M-H data satisfies the flux creep model.

title: "It's wonderful becoming a mother...I don't think I am a mum with multiple sclerosis, I'm a mum". The lived experience of mothers with multiple sclerosis in Italy
Creators: name: Willson, Catherine Louise
Publisher: name: The Open University
Year: 2013

description: This qualitative study explored the experiences of mothers with multiple sclerosis in Italy, who are an underrepresented group in the academic literature. Few studies have considered the maternal experiences of women with MS, and those that have focus on pregnancy and its impact on the disease, with the wider literature on motherhood and disability concentrating more on women who became mothers when aware of their impairments. This study involved this latter group, but also included women who were diagnosed after becoming mothers. With phenomenology guiding the methodology, in-depth interviews were conducted (n=16) with women at various stages of MS, with some follow up interviews (n=7). The study explored what factors impacted on the mothering role; the relevance of the timing of diagnosis; any impact of external barriers, and the Significance of wider socio-cultural and political influences. The analysis was conducted using interpretative phenomenological analysis (IPA), from which three overarching themes emerged - self and identity, relationships with others, and challenges and support within society. Self and identity centered on how the participants viewed their role as mothers, with some adjusting their roles in light of their impairments. Relationships concerned the value of friendships and asking for and receiving help from family members. How women discussed their MS with their children, and reactions to this was also discussed, which was particularly relevant regarding the timing of when the women received their diagnosis. Many women faced barriers within society from others' attitudes, including a lack of government support, but also because of physical barriers which affected how they fulfilled their role as mothers. The study findings have implications for practice, which require further investigation. These include recognising the potential of the family in providing empowering support, and the value associated with being a mother, rather than solely focusing on doing motherhood.

description: We examine the gendered responses to shocks – including HIV-related illness and death, and environmental factors such as drought or too much rain – and how women in south western Uganda navigate structural barriers such as the gender constraints in land ownership, to cope with the impact of shocks. The study is based on data drawn from households selected from a General Population Cohort of 20,000 people in Kalungu District. As part of a larger study investigating the impact of HIV on agricultural livelihoods, 22 households were purposively sampled for a qualitative study. These households were stratified by sex of household head and by a death having occurred/not occurred of an HIV-positive individual in the household. Our findings show the gendered dimensions in household responses to crises are shaped by women and men’s position in the social structure in general and within their families and households. Women can make effective use of their social relations to obtain material support and information to improve their family’s livelihood.

description: Collaborating among smallholder farm households, such as through marketing groups, is a wellestablished strategy for improving livelihoods. While the potential benefits are well known, so too are the potential challenges. One particular challenge is farm households in strongly familist, patriarchal societies such as rural Pakistan being unwilling or unable to collaborate with other households outside the family. In such societies, women may be more amenable to such collaborations than men. This paper uses data from a household survey in rural Pakistan to test the potential for collaboration among households in rural Pakistan and concludes that in households where women are empowered in household decision-making, the potential for collaboration with other households is significantly enhanced.

description: We investigate the temporal evolution of a ferromagnetic system of Ising spins evolving under Kawasaki dynamics from a random initial condition, in spatial dimensions one and two. We examine in detail the asymptotic behaviour of the two-time correlation and response functions. The linear response is measured without applying a field, using a recently proposed algorithm. For the chain at vanishingly small temperature, we introduce an accelerated dynamics which has the virtue of projecting the system into the asymptotic scaling regime. This allows us to revisit critically previous works on the behaviour at large time of the two-time autocorrelation and response functions. We also analyse the case of the two-dimensional system at criticality. A comparison with Glauber dynamics is performed in both dimensionalities, in order to underline the similarities and differences in the phenomenology of the two dynamics.

description: The optimization of information visualizations is time consuming and expensive. To reduce this we propose an improvement of existing optimization approaches based on user-centered design, focusing on readability, comprehensibility, and user satisfaction as optimization goals. The changes comprise (1) a separate optimization of user interface and representation, (2) a fully automated evaluation of the representation, and (3) qualitative user studies for simultaneously creating and evaluating interface variants. On the basis of these results we are able to find a local optimum of an information visualization in an efficient way.

description: Improved maize seed varieties are bred with characteristics such as drought and disease tolerance which may not capture farmers’ preference. It is therefore, imperative to consider attributes that are preferred by farmers in developing maize seed varieties. This research was conducted to determine attributes that are most preferred by smallholder maize farmers in Tanzania. Specifically, the study aimed to (i) characterize smallholder farmers’ preferences for improved maize seed varieties depending on their socio-economic characteristics, (ii) assess the heterogeneity of farmers’ preferences for improved maize seed varieties and (iii) determine factors that influence farmers’ choice of the most preferred improved maize seed varieties. Descriptive statistics and binary logistic regression were used for data analysis. The study findings revealed that majority (74.7%) of the households were male-headed and (83%) were married. About 90 percent of the farmers had no access to extension services that is supposed to play an important role in agricultural information dissemination. The most preferred improved maize varieties in all zones were PAN6549, SC 627, SC 713, STAHA, KILIMA and DK 8371due to higher production potential. A Logit model showed that agro-ecological zones, farm size, household size and yield positively influenced the likelihood of farmers’ choice of improved maize seed varieties. Based on these findings, it is recommended that researchers and suppliers of seed should consider the attributes of farmers’ preference in the production of improved maize seeds and put more emphasis on facilitating the delivery of agricultural extension services for more effective uptake of agricultural technologies.

description: We determine the mass of the lightest quark-antiquark scalar meson with I=1 using the simulation with two dynamical Domain Wall Fermions. The conventional exponential fit of the scalar correlator is justified in this case giving the mass 1.58 +/- 0.34 GeV. In general the scalar correlator receives also the bubble contribution, which is the intermediate state with two pseudoscalar mesons. This contribution is sizable at light quark masses and has to be incorporated in the fit of the scalar correlator in order to extract the scalar meson mass. We provide predictions for the bubble contribution in Partially Quenched ChPT, Staggered ChPT and ChPT for Mixed quark actions. We find that the bubble contribution is significantly affected by the unphysical approximations that are employed in simulations. It can render the negative sign and unphysical effective mass 2*Mpi in the scalar correlator with I=1.

description: The generalized Gerasimov-Drell-Hearn sum rule $I^{GDH}_{γ^*d}(Q^2)$ for deuteron electrodisintegration $d(e,e')np$ as function of the squared four-momentum transfer $Q^2$ is evaluated by explicit integration. The calculation is based on a conventional nonrelativistic framework using a realistic $NN$-potential and including contributions from meson exchange currents, isobar configurations and leading order relativistic terms. Good convergence is achieved. The prominent feature is a deep negative minimum, $I_{γ^* d}^{GDH}=-9.5$ mb, at low $Q^2\approx 0.2$ fm$^{-2}$ which is almost exclusively driven by the nucleon isovector anomalous magnetic moment contribution to the magnetic dipole transition to the $^1S_0$-state. Above $Q^2=20$ fm$^{-2}$ the integral $I^{GDH}_{γ^*}(Q^2)$ approaches zero rapidly.

description: We propose a model of the Peierls transition (PT) taking into account amplitude fluctuations of the charge-density waves and spontaneous thermally activated suppression of the Peierls gap, akin to the phase slip process. The activation results in the exponential growth of the normal phase with increasing temperature. The model fairly describes the behavior of resistance, thermal expansion, Young modulus and specific heat both below and above the PT temperature $T_P$. The PT appears to have a unique nature: it does not comprise $T_P$ as a parameter, and at the same time it has features of the 1st order transition. The possible basis for the model is activation of non-interacting amplitude solitons perturbing large volumes around them.

description: This paper estimates exchange rate pass-through for Australian manufactured imports by applying an econometric procedure which avoids the pit-falls in previous studies to a carefully assembled data set. For the first time, we provide estimates of pass-through based on the Johansen (1988) ML procedure. Our finding of incomplete passthrough has important implications for policy and the macroeconomy. Incomplete pass-through brings into question the validity of the "small" country assmption and the exogeneity of the terms of trade with respect to exchange rate changes. We may also have to reconsider the extent of the apparent inflationary (deflationary) consequences of exchange rate depreciations (appreciations), and the effects of exchange rate variability on international trade flows.

description: In 1989 a major project entitled "Strategies for Environmentally Sound Economic Decelopment" was inaugurated under the sponsorship of the United Nations. This project is designed to identify ways of alleviating pressures on the global environment and, at the same time, raise the standard of living of the poorest countries. The central component of its analytical framework is a dynamic global input-output model (GIOM) that describes trade between 15 regions in about 50 commodities, taking as its starting point the well known 1977 World Input-Output Model of Leontief, Carter and Petri. The purpose of the present paper is twofold. Firstly, it describes a contribution to the compilation of a database for the GIOM. In particular, it draws on data collected by the United Nations' International Comparison Project (ICP) to provide estimates of private consumption expenditure for 1980, the base period for the model. Secondly, it uses these estimates as a case study to examine the implications of using different price systems for each country, rather than a common set of prices, to determine expenditures on composite commodities. In preparing data for multisectoral global models, it is common practice to collect expenditure data evaluated in local (national) prices and convert to world prices using published exchange rates. The analysis of this paper suggests that, when commodities produced in different countries are treated as perfect substitutes in the model, the practice may seriously compromise the model's results.

description: We describe the theory, computation and results of a multiperiod general equilibrium model designed to assist an urban water authority in Its pricing and investment decisions. The model includes gestation periods in the creation of dams, main sewers and treatment plants. It allows for lumpy capital items and recognizes cost differences in the provision of services in peak and non-peak times. Its general equilibrium framework is convenient for handling links between the water authority and the rest of the economy, especially the housing sector. We have used two computational approaches. In the first, we reformulate the model as a single-entity optimization problem and then apply a linear programming package. We have found that a better approach is to apply Newton-Raphson methods to a formulation of the model as a set of equations depicting purely competitive behaviour in all productive activities. A special feature of this paper is an integration of the model's results, obtained under the assumption of certainty, with data on weather-induced variations in streamflow and demand. Using Monte Carlo techniques we assess the risks of water shortages associated with the investment and pricing strategies that our model indicates. Key Words and Phrases : water pricing and investment: uncertain streamflow: water policy in a general equilibrium model: water policy for Melbourne: linear programming: Newton-Raphson: Monte Carlo: peak and non-peak.

description: Around 80% of global trade by volume is transported by sea, and thus the maritime transportation system is fundamental to the world economy. To better exploit new international shipping routes, we need to understand the current ones and their complex systems association with international trade. We investigate the structure of the global liner shipping network (GLSN), finding it is an economic small-world network with a trade-off between high transportation efficiency and low wiring cost. To enhance understanding of this trade-off, we examine the modular segregation of the GLSN; we study provincial-, connector-hub ports and propose the definition of gateway-hub ports, using three respective structural measures. The gateway-hub structural-core organization seems a salient property of the GLSN, which proves importantly associated to network integration and function in realizing the cargo transportation of international trade. This finding offers new insights into the GLSN's structural organization complexity and its relevance to international trade.

description: GEMPACK is a suite of general-purpose economic modelling software especially suitable for general and partial equilibrium models. It can handle a wide range of economic behaviour and also contains a versatile method for solving intertemporal models. GEMPACK provides software for calculating accurate solutions of an economic model, starting from an algebraic representation of the equations of the model. These equations can be written as levels equations, linearized equations or a mixture of these two. The software provides a range of utility programs for handling the economic data base and the results of simulations, and is fully documented from a user's point of view. GEMPACK is used to implement and solve a number of economic models including several single-country models (of which the ORANI model of Australia is perhaps the best known), multi-country trade models, regional models and intertemporal (or dynamic) models. GEMPACK runs on a wide variety of computers including 80386/80486 microcomputers running DOS, Windows or OS/2, Apple Macintosh computers, Unix machines, DEC VAX and Alpha machines running VMS. This paper gives an overview of the current release of GEMPACK (Release 5.1, April 1994). Included are descriptions of • the algebra-like language used to describe and document the equations of an economic model, • the operation of the pre-processor TABLO which converts the equations of the model to a form suitable for computing solutions of the model, • the solution methods used for producing accurate solutions of the model, • the facilities for specifying and carrying out simulations, including the options for varying the choice of endogenous and exogenous variables and the variables shocked, • the condensation facility which makes it possible to solve very large models, • the utility programs for assisting in managing the data bases on which models are based, • the different versions of GEMPACK.

description: Smart and decentralized control systems have recently been proposed to handle the growing traffic congestion in urban cities. Proposed smart traffic light solutions based on Wireless Sensor Network and Vehicular Ad-hoc NETwork are either unreliable and inflexible or complex and costly. Furthermore, the handling of special vehicles such as emergency is still not viable, especially during busy hours. Inspired by the emergence of distributed smart cameras, we present a novel approach to traffic control at intersections. Our approach uses smart cameras at intersections along with image understanding for real-time traffic monitoring and assessment. Besides understanding the traffic flow, the cameras can detect and track special vehicles and help prioritize emergency cases. Traffic violations can be identified as well and traffic statistics collected. In this paper, we introduce a flexible, adaptive and distributed control algorithm that uses the information provided by distributed smart cameras to efficiently control traffic signals. Experimental results show that our collision-free approach outperforms the state-of-the-art of the average user's waiting time in the queue and improves the routing of emergency vehicles in a cross congestion area.

description: We report recent results in rare B decays. Our focus will be on b -> d gamma and b -> s l^+ l^- transitions. We discuss their impact on the CKM phenomenology and their role within our search for new physics. In particular, we analyse the impact of a recent lattice QCD estimate of the B -> K* form factor at zero recoil. We also briefly discuss the presently available optimal theoretical tools for the inclusive and exclusive modes.

description: In the light of new experimental results on $B \to Kπ$ decays, we study the decay processes $B \to K π$ in the framework of both R-parity conserving (SUGRA) and R-parity violating supersymmetric models. We find that any possible deviations from the Standard Model indicated by the current data for the branching ratios and the direct CP asymmetries of $B \to Kπ$ can be explained in both R-parity conserving SUGRA and R-parity violating SUSY models. However, there is a difference between the predictions of both models to the time-dependent CP asymmetry observable $S_{K_{_S} π^0}$ whose current experimental results include large uncertainties. We demonstrate that this difference can be useful for testing both models with more accurate data for $S_{K_{S} π^0}$ and $A_{CP}^{+-}$ in the near future.

description: Background and objectives: Parkinson's disease is a neurological disorder that affects the motor system producing lack of coordination, resting tremor, and rigidity. Impairments in handwriting are among the main symptoms of the disease. Handwriting analysis can help in supporting the diagnosis and in monitoring the progress of the disease. This paper aims to evaluate the importance of different groups of features to model handwriting deficits that appear due to Parkinson's disease; and how those features are able to discriminate between Parkinson's disease patients and healthy subjects. Methods: Features based on kinematic, geometrical and non-linear dynamics analyses were evaluated to classify Parkinson's disease and healthy subjects. Classifiers based on K-nearest neighbors, support vector machines, and random forest were considered. Results: Accuracies of up to $93.1\%$ were obtained in the classification of patients and healthy control subjects. A relevance analysis of the features indicated that those related to speed, acceleration, and pressure are the most discriminant. The automatic classification of patients in different stages of the disease shows $κ$ indexes between $0.36$ and $0.44$. Accuracies of up to $83.3\%$ were obtained in a different dataset used only for validation purposes. Conclusions: The results confirmed the negative impact of aging in the classification process when we considered different groups of healthy subjects. In addition, the results reported with the separate validation set comprise a step towards the development of automated tools to support the diagnosis process in clinical practice.
