description: We consider the three dimensional SU(2) Yang-Mills theory with adjoint static color sources, studying by lattice simulations how the shape of the flux tube changes when increasing the distance between them. The disappearance of the flux tube at string breaking is quite abrupt, but precursors of this phenomenon are present already when the separation between the sources is smaller than its critical value, a fact that influences also some details of the static potential.

title: Mathematical Models for Optimisation of Drug Administration in Intensive Care Units
Creators: name: Finazzi, Stefano
Publisher: name: The Open University

description: Clinical status of critically ill patients is often extreme and rapidly evolving. Hence, pharmacological therapies must be tailored to patients' characteristics and adapted according to the evolution of their clinical pictures. To identify optimal personalized treatments, possible scenarios produced by different therapeutic choices must be predicted and compared. This process requires complex analyses involving the development of appropriate mathematical models. In this Thesis, I focused on two important aspects of the pharmacological treatment of critically ill patients: the administration of antimicrobial drugs and the control of their glycaemic level. Although these problems are clinically very different, the modelling of their pathophysiological mechanisms can be addressed with similar tools. I performed analyses based on retrospective clinical data collected with MargheritaTre, an electronic health record developed by GiViTI. The software to synchronize databases from hospitals to our laboratory and to preprocess data for analyses was written for the purpose of this Thesis. Starting from the study of the physiological mechanisms at the basis of vancomycin pharmacokinetics I constructed a model to describe the evolution of the plasma concentration of this drug in critically ill patients. Compartment models were fitted on a sample of 141 patients, testing about 30 patient covariates and several functional dependencies for each variable. Glucose dynamics were described through a system of delay differential equations reproducing intake, uptake and endogenous production of glucose, and organ-organ interactions mediated by hormones. Existing models, describing only the dynamics of glucose and insulin, fail to reproduce the correct evolution when glucose concentrations vary too rapidly. I improved these models, by introducing an equation describing glucagon dynamics and taking into account its effect on glucose metabolism. I investigated the dynamical properties of my model with analytical analyses, numerical simulations and fitting it to observed data.

description: The Raman-active phonons in perovskite-like LaMn1-xCoxO3 (x = 0, 0.2, 0.3, 0.4, and 1.0) were studied by measuring Raman spectra at temperatures of 295 and 5 K. The changes in the spectra with Co doping are correlated with the decrease of orthorhombic distortions. Surprisingly more phonon lines than allowed for the rhombohedral LaCoO3 structure were observed in the spectra.

title: Teaching Undergraduate Medical Students: Exploring The Clinical Teacher Experience
Creators: name: Bussey, Sonia
Publisher: name: The Open University
Year: 2019

description: Clinical teachers are responsible for the workplace teaching of Bachelor of Medicine, Bachelor of Surgery (MBBS) undergraduate medical students in the UK. The aim of this project is to investigate how clinical teachers experience their role within the foundations of clinical practice (FoCP) rotation of an undergraduate MBBS medical degree offered by a University in the North of England. Semi-structured interviews were conducted with thirteen clinical teachers involved in the delivery of the FoCP rotation (delivered during year three of the MBBS programme). An inductive approach based on a social constructivist philosophy was adopted, and thematic analysis used to identify emergent themes from participants. Twenty-nine documentary sources from the university were subsequently collected and used to contextualise the emergent interview themes. The findings of the research indicate that the role of the clinical teacher is opaque and changeable. Those clinical teachers with professional backgrounds other than medicine expressed different support and development requirements than medically trained teachers. Preparation for a clinical teaching role was described as a continuum that extended from a teacher’s own undergraduate experience to handover at the end of a teaching post. Although career role models were perceived as important for teachers to plan a career in medical education, there was widespread difficulty in identifying suitable role models. Theoretical outcomes of this research are the importance of identity as a concept, the value of role models in educational career planning and the representation of clinical teacher role preparation as an extended continuum. This research is likely to have important implications for how clinical teachers are prepared, supported and developed. A better understanding of the relationships between the identities, experiences and development of clinical teachers could assist the University in matching the ‘university offer’ of staff development and support with teachers’ needs.

description: Designing a single neural network architecture that performs competitively across a range of molecule property prediction tasks remains largely an open challenge, and its solution may unlock a widespread use of deep learning in the drug discovery industry. To move towards this goal, we propose Molecule Attention Transformer (MAT). Our key innovation is to augment the attention mechanism in Transformer using inter-atomic distances and the molecular graph structure. Experiments show that MAT performs competitively on a diverse set of molecular prediction tasks. Most importantly, with a simple self-supervised pretraining, MAT requires tuning of only a few hyperparameter values to achieve state-of-the-art performance on downstream tasks. Finally, we show that attention weights learned by MAT are interpretable from the chemical point of view.

description: We consider electron transport along a single-mode channel which is in contact, via tunnel junctions in its walls, with two quantum dots. Electron tunneling to and from the dots contributes to the electron backscattering, and thus modifies the channel conductance. If the dots carry spin, the channel conductance becomes temperature dependent due to the Kondo effect. The two-dot device geometry allows for a formation of S=1 localized spin due to the indirect exchange interaction, called Ruderman-Kittel-Kasuya-Yosida interaction. This device offers a possibility to study the crossover between fully screened and under-screened Kondo impurity. We investigate the manifestation of such crossover in the channel conductance.
Effects of Polaron Formation in Semiconductor Quantum Dots on Transport Properties

description: We theoretically examine the effects of polaron formation in quantum dots on the transport properties. When a separation between two electron-levels in a quantum dot matches the energy of the longitudinal optical (LO) phonons, the polarons are strongly formed. The Rabi splitting between the levels is observable in a peak structure of the differential conductance G as a function of the bias voltage. The polaron formation suppresses the peak height of G, which is due to the competition between the resonant tunneling (resonance between a level in the dot and states in the leads) and the polaron formation (Rabi oscillation between two levels in the dot). G shows a sharp dip at the midpoint between the split peaks. This is attributable to the destructive interference between bonding and anti-bonding states in a composite system of electrons and phonons.

Angular Momentum Transport by Internal Gravity Waves II- Pop II stars from the Li plateau to the horizontal branch

Subjects: subject: Astrophysics (astro-ph)

description: This paper is the second in a series where we examine the generation and filtering of internal gravity waves in stars and the consequences of wave induced transport of angular momentum at various stages of the stellar evolution. Here we concentrate on Pop II dwarf stars and we focus in particular on the differential properties of internal gravity waves as a function of the stellar mass. We show that, for the range of masses corresponding to the lithium plateau, gravity waves are fully efficient and should thus lead to a quasi-solid rotation state, similar to that of the Sun. In the slightly more massive progenitors of currently observed horizontal branch star however, internal wave generation is not efficient on the main sequence, and large internal differential rotation can thus be maintained. This leads to a natural explanation of the large rotational velocities measured on the horizontal branch in some globular clusters.

title: Exploring Neuro-immune Networks in Cancer: Focus on Macrophages
Creators: name: Cortese, Nina
Publisher: name: The Open University
Year: 2019

description: This thesis is composed of two parts; the first one summarizes results of two ancillary projects I was involved in, which have been fundamental to provide the ground to my PhD project. The first project (“TAM-CTX Project”) concerns the interaction of tumour-associated macrophages with chemotherapy in pancreatic cancer. The second project (“BAT Project”) was carried out in the laboratory of Prof. Steffen Jung, at the Weizmann Institute in Rehovot, and contributed to the definition of the important role of macrophages in the control of tissue innervation. The main part of the thesis includes the results of my PhD project (“Neuro-immune Project”) and is focused on the analysis of neuro-immune networks in cancer. The central nervous system reflexively regulates the inflammatory response, via a direct modulation of immune cells by peripheral nerves. In the context of cancer this phenomenon is still largely unexplored. Macrophages hold a key position in neural-mediated circuits. To define whether a neural control of macrophage functions in tumours exists, we have investigated the macrophage-neural interaction in a preclinical model of colorectal cancer (AOM/DSS). Firstly, we characterized by confocal microscopy the major components (neurons and Enteric Nervous System (ENS)-associated glia) of the neural networks in the gastrointestinal wall, peculiarly organized in each layer. We have visualized the spatial interaction of the complex intestinal neural networks with macrophages. F4/80+ macrophages were found in closed proximity to nerve fibers throughout the intestinal wall. We found a closer association of macrophages to nerves in tumor bearing mice. We hypothesized that this could be due to a neural remodelling process, and in fact tumour-bearing mice showed a significantly higher number of Nestin+ cells, possibly suggesting the recruitment of neural progenitor cells. Moreover, macrophages isolated from AOM/DSS treated mice up-regulated a neuro-modulatory profile, and in particular we found an increased expression in Neuregulin 1, a protein with pivotal role in the nervous and cardiovascular systems. The increased expression of Neuregulin 1 in colonic macrophages of tumour-bearing mice was further confirmed by immunofluorescence on tissue and single cell RNA-sequencing. Overall, these results intimate a modification of neural-macrophage networks in colorectal cancer that could be important in the regulation of macrophage function in tumours.

description: It is evident that in the realm of gender studies concerning the Maghreb, many scholars have studied literary texts from prominent female Maghrebi writers such as Assia Djebar and Fatima Mernissi. However, certain forms of expression have been neglected, such as film. The purpose of this work is to analyze and evaluate how cinema has portrayed the situation of women in the postcolonial Maghreb. I will be examining two examples of Maghrebi cinema which include the Tunisian film Les silences du palais by Moufida Tlatli and the Algerian film Viva Laldjérie by Nadir Moknèche. Through the examination of these two films it is clear that both address larger issues experienced by Maghrebi women such as objectification, classism, and gender violence, while also portraying issues specific to each country such as imperial structures that suppress women in Tunisia, and rising extremism in Algeria.

description: The theoretical framework for networked quantum sensing has been developed to a great extent in the past few years, but there are still a number of open questions. Among these, a problem of great significance, both fundamentally and for constructing efficient sensing networks, is that of the role of inter-sensor correlations in the simultaneous estimation of multiple linear functions, where the latter are taken over a collection local parameters and can thus be seen as global properties. In this work we provide a solution to this when each node is a qubit and the state of the network is sensor-symmetric. First we derive a general expression linking the amount of inter-sensor correlations and the geometry of the vectors associated with the functions, such that the asymptotic error is optimal. Using this we show that if the vectors are clustered around two special subspaces, then the optimum is achieved when the correlation strength approaches its extreme values, while there is a monotonic transition between such extremes for any other geometry. Furthermore, we demonstrate that entanglement can be detrimental for estimating non-trivial global properties, and that sometimes it is in fact irrelevant. Finally, we perform a non-asymptotic analysis of these results using a Bayesian approach, finding that the amount of correlations needed to enhance the precision crucially depends on the number of measurement data. Our results will serve as a basis to investigate how to harness correlations in networks of quantum sensors operating both in and out of the asymptotic regime.

description: Originally a speculative pattern in ecological networks, the hybrid or compound nested-modular pattern has been confirmed, during the last decade, as a relevant structural arrangement that emerges in a variety of contexts --in ecological mutualistic system and beyond. This implies shifting the focus from the measurement of nestedness as a global property (macro level), to the detection of blocks (meso level) that internally exhibit a high degree of nestedness. Unfortunately, the availability and understanding of the methods to properly detect in-block nested partitions lie behind the empirical findings: while a precise quality function of in-block nestedness has been proposed, we lack an understanding of its possible inherent constraints. Specifically, while it is well known that Newman-Girvan's modularity, and related quality functions, notoriously suffer from a resolution limit that impairs their ability to detect small blocks, the potential existence of resolution limits for in-block nestedness is unexplored. Here, we provide empirical, numerical and analytical evidence that the in-block nestedness function lacks a resolution limit, and thus our capacity to detect correct partitions in networks via its maximization depends solely on the accuracy of the optimization algorithms.

description: Nepal is a developing country located in South Asia with high economic dependency on agriculture. Eighty percent of the population works in the agricultural sector, generating 40% of the GDP. Livestock is an important part of mixed farming with dairy generating about two-thirds of the livestock GDP. Almost three-fourths of the households in Nepal keep cattle and one-half keep buffalo for milk production. Even with a larger percentage of the animals being cattle, buffalo produced 71% of the milk. Cost of production is higher for cattle because cattle productivity declines after 5 to 6 lactations but must be kept in the herd because cattle cannot be slaughtered because of religious based policy. This makes milk production cost higher and reduces the competitiveness of milk in south Asia. The no slaughter policy puts Nepal at a disadvantage to other growers in south Asia. The purpose of this study was to assess the cost of production for producing milk and the impact of no slaughter policies on producers. Monte Carlo simulations were completed to quantify a baseline and alternative scenarios for milk production. Our results suggest that milk production would increase significantly allowing domestic consumption and trade to increase as well.

description: The Intra-Cluster Medium (ICM) is a rarefied, hot, highly ionized, metal rich, weakly magnetized plasma. In these proceeding, after having reviewed some basic ICM properties, I discuss recent results obtained with the BeppoSAX, XMM-Newton and Chandra satellites. These results are summarized in the following five points. 1) Currently available hard X-ray data does not allow us to constrain B fields in radio halos, the advent of hard X-ray telescopes in a few years may change the situation substantially. 2) There is mounting evidence that temperature profiles of clusters at large radii decline; however investigation of the outermost regions will have to await a new generation of yet unplanned but technologically feasible experiments. 3) The ICM is polluted with metals, the enrichment has probably occurred early on in the cluster's life. The abundance excess observed at the center of CC clusters is due to the giant elliptical always found in these systems. 4) Chandra and XMM-Newton observations of relaxed clusters have falsified the previously accepted cooling flow model, heating mechanisms that may offset the cooling are actively being sought. 5) The superb angular resolution of Chandra is allowing us to trace a previously unknown phenomenon intimately related to the formation of galaxy clusters and of their cores.

description: The Alma Mater Society (AMS) of the University of British Columbia (UBC) is experiencing low awareness and participation among students and staff despite the wide array of sustainability initiatives and services offered. This is largely due to the lack of unified branding and consistent marketing promotions. The current strategies employed by the AMS to promote its sustainability initiatives were researched through interviews with the AMS Food and Beverages Manager, as well as various sustainability program coordinators at UBC. The current level of awareness for existing sustainability initiatives was measured through surveys that were distributed to students, faculty, and staff. After thoroughly analyzing survey results and conducting further secondary research with similar organizations, this proposal consists of the following recommendations: 1. Maximize awareness by bringing all current AMS sustainability initiatives underneath one consistent and unified “AMS” brand. 2. Enhance the online presence of the AMS‟s sustainability initiatives 3. Offer sustainability volunteer positions and opportunities 4. Increase internal AMS staff awareness By implementing the changes proposed above, the AMS will benefit from the following: •Improved communication, awareness, and participation of existing sustainability initiatives from students, faculty, and staff. •A foundation for a strong and consistent “AMS Sustainability” brand presence on the UBC campus. The long term benefit from the proposed recommendations will exceed the initial cost of the implementation. After the implementation, the AMS should conduct annual surveys to monitor the level of awareness and attitude of students, faculty and staff. It is critical to obtain feedback from target audiences on a regular basis. Disclaimer: “UBC SEEDS provides students with the opportunity to share the findings of their studies, as well as their opinions, conclusions and recommendations with the UBC community.

description: Learning abstract and systematic relations has been an open issue in neural network learning for over 30 years. It has been shown recently that neural networks do not learn relations based on identity and are unable to generalize well to unseen data. The Relation Based Pattern (RBP) approach has been proposed as a solution for this problem. In this work, we extend RBP by realizing it as a Bayesian prior on network weights to model the identity relations. This weight prior leads to a modified regularization term in otherwise standard network learning. In our experiments, we show that the Bayesian weight priors lead to perfect generalization when learning identity based relations and do not impede general neural network learning. We believe that the approach of creating an inductive bias with weight priors can be extended easily to other forms of relations and will be beneficial for many other learning tasks.

Power Spectrum Normalisation and the Non-Gaussian Halo Model

Year: 2003

description: The normalisation of the matter power spectrum, sigma_8, is an essential ingredient to predict the phenomenology of the low redshift universe. It has been measured using several methods, such as X-ray cluster counts, weak lensing and the cosmic microwave background, which have yielded values ranging from 0.7 to 1.0. While these differences could be due to systematic effects, they could also be due to physics beyond the standard LambdaCDM model. An obvious possibility is the presence of non-Gaussian initial fluctuations in the density field. To study the impact of non-Gaussianity on each of these methods, we use a generalised halo model to compute cluster counts and the non-linear power spectrum for non-Gaussian models. Assuming scale invariance, the upper-limits on non-Gaussianity from the WMAP CMB experiment correspond to roughly a 4% shift in sigma_8 as measured from cluster counts and about 2% shift through weak lensing. This is not enough to account for the current internal and mutual discrepancies between the different methods, unless non-Gaussianity is strongly scale dependent. A comparison between future X-ray surveys with a two fold improvement in cluster mass calibration and future cosmic shear surveys with 400 deg^2 will be required to constrain non-Gaussianity on small scales with a precision matching that of the current CMB constraints on larger scales. Our results argue for the presence of systematics in the current cluster and cosmic shear surveys, or to non-standard physics other than non-Gaussianity.

description: Ferromagnetic metals and insulators are widely used for generation, control and detection of magnon spin signals. Most magnonic structures are based primarily on either magnetic insulators or ferromagnetic metals, while heterostructures integrating both of them are less explored. Here, by introducing a Pt/yttrium iron garnet (YIG)/permalloy (Py) hybrid structure grown on Si substrate, we studied the magnetic coupling and magnon transmission across the interface of the two magnetic layers. We found that within this structure, Py and YIG exhibit an antiferromagnetic coupling field as strong as 150 mT, as evidenced by both the vibrating-sample magnetometry and polarized neutron reflectometry measurements. By controlling individual layer thicknesses and external fields, we realize parallel and antiparallel magnetization configurations, which are further utilized to control the magnon current transmission. We show that a magnon spin valve with an ON/OFF ratio of ~130% can be realized out of this multilayer structure at room temperature through both spin pumping and spin Seebeck effect experiments. Thanks to the efficient control of magnon current and the compatibility with Si technology, the Pt/YIG/Py hybrid structure could potentially find applications in magnon-based logic and memory devices.

description: Solid waste, which typically consists of metals, plastics, glasses, paper, wood, and organics, is generated and accumulated due to human day to day activities. The waste often leads to ecological pollution unless an appropriate solid waste management system is applied. Remarkably, solid waste can be channeled into a very useful form to generate energy leading to the reduction of the use of fossils fuels which are rapidly becoming limited, reduction
of wastes in dumping sites and also be an additional source of energy. For such ventures though, the amount of
energy that can be recovered from burning solid waste needs to be determined. In this work, solid waste samples
were collected, classified, sundried, powdered and sieved using a sieve of size 500μm. The percentage moisture content of fruits waste, animal dung, and yard trimming & vegetables were found to be 33, 48, and 55 % respectively. The fruits waste had the highest calorific value of 104,130.91J/g, followed by the animal dung with
95,804.13 J/g and the least was yard trimming and vegetables with 95,100.39 J/g. The average specific energy
content is 98345.14 J/g.

description: We study the evolution of the circumstellar medium of massive stars. We pay particular attention to Wolf-Rayet stars that are thought to be the progenitors of some long Gamma-Ray Bursts. We detail the mass-loss rates we use in our stellar evolution models and how we estimate the stellar wind speeds during different phases. With these details we simulate the interactions between the wind and the interstellar medium to predict the circumstellar environment around the stars at the time of core-collapse. We then investigate how the structure of the environment might affect the GRB afterglow. We find that when the afterglow jet encounters the free-wind to stalled-wind interface that rebrightening occurs and a bump is seen in the afterglow light curve. However our predicted positions of this interface are too distant from the site of the GRB to reach while the afterglow remains observable. The values of the final-wind density, A_{*}, from our stellar models are similar to the values inferred from observed afterglow lightcurves and those from observed Wolf-Rayet stars. However we do not reproduce the lowest observed A_{*} values below 0.3. For these cases we suggest that the progenitors could have been a WO type Wolf-Rayet star, be in a close binary or very low metallicity star. Finally we turn our attention to the matter of stellar wind material producing absorption lines in the afterglow spectra. We discuss the observational signatures of two Wolf-Rayet stellar types, WC and WO, in the afterglow lightcurve and spectra. We also indicate how it may be possible to constrain the initial mass and metallicity of a GRB progenitor by using the inferred wind density and wind velocity.

Universal behavior of crossover scaling functions for continuous phase transitions

description: We consider two different systems exhibiting a continuous phase transition into an absorbing state. Both models belong to the same universality class, i.e., they are characterized by the same scaling functions and the same critical exponents. Varying the range of interactions we examine the crossover from the mean-field-like to the non-mean-field scaling behavior. A phenomenological scaling form is applied in order to describe the full crossover region which spans several decades. Our results strongly supports the hypotheses that the crossover function is universal.

description: Almost a quarter of South Africa's agricultural production is lost annually due to adverse weather. About 9 per cent of this is due to hail damage. This paper examines some spatial aspects of hail damage to maize in the Transvaal, using hail insurance data for the 1981/82 - 1986/87 period. In addition, the effect of hailstorm frequency, size and intensity as well as the susceptibility of maize to hail damage are discussed and hail risk zones delineated. The analyses indicate, inter alia, that the highest crop loss occurred in the Belfast, Bethal, Pretoria and Krugersdorp districts and that the likelihood of hail damage (i.e. the hail risk) is highest in the south, south eastern and south central parts of the Transvaal.

description: In this study, the coefficients of thermal conductivities have been determined. The goal was to
find out the best insulator among the recyclable and locally available materials which can be adopted for
use to replace the existing thermal insulation. Rice husks, dry grass, sawdust and old/used newspapers
have been studied in this study using Lees’ disc method. The results showed that grass can do best as an
insulating material though all the samples can be used as insulators. They all have low thermal
conductivities. The coefficient of thermal conductivities ranged from 𝟎. 𝟐𝟐𝟔 𝑾/𝒎𝑲 for grass,
𝟎. 𝟐𝟕 𝑾/𝒎𝑲 for saw dust, 𝟎. 𝟓𝟎 𝑾/𝒎𝑲 for rice husks and 𝟏. 𝟗𝟑 𝑾/𝒎𝑲 for newspaper cut-outs. Due to
their local abundance, and no much competing commercial interest, we recommend the studied
materials as suitable thermal insulators.

description: We describe inflation in terms of a time dependent quantum density matrix with time playing the role of a stochastic variable. Using a quasi-de Sitter model we compute the corresponding quantum Fisher information function as the second derivative of the relative entanglement entropy for the density matrix at two different times. Employing standard quantum estimation theory we evaluate the minimal variance of quantum scalar fluctuations that reproduces the power spectrum and the corresponding tilt in the slow roll limit. The Jeffreys prior associated with such Fisher information can be used to define the probabilities on the set of initial conditions defined by the slow roll parameter $ε$ and the initial Shannon information.

description: Prices should be non-distortive signals for production and consumption. Deterministic price behaviour patterns (cycles) and rainfall cycles resulted in cyclical supply variation through a process of herd expansion/liquidation. This apparently promoted inefficient management strategies at farm level and distorted production and marketing of beef. Significant seven year supply cycles for beef were isolated and used to determine producers' supply response flexibilities to rainfall and price cycle variation. Multiple regression analysis with distributed lag models were used. Significant lagged supply responses indicate that price signals were distorted and aided the climatological inflexibilities of beef production. Nominal beef producer prices were not stabilised and the control measures, employed for this purpose, effectively reduced farmers' marketing opportunities and thereby increase their exposure to production, price, marketing and income risks. Controlled marketing of red meat failed to stabilise producer prices of beef or to promote the producers' interests.

description: The magnetization curves M(H) for ideal type-II superconductors and the maximum, minimum, and saddle point magnetic fields of the vortex lattice are calculated from Ginzburg-Landau theory for the entire ranges of applied magnetic fields Hc1 <= H < Hc2 or inductions 0 <= B < Hc2 and Ginzburg-Landau parameters sqrt(1/2) <= kappa <= 1000. Results for the triangular and square flux-line lattices are compared with the results of the circular cell approximation. The exact magnetic field B(x,y) and magnetization M(H, kappa) are compared with often used approximate expressions, some of which deviate considerably or have limited validity. Useful limiting expressions and analytical interpolation formulas are presented.
