description: Gaussian multiplicative chaos was first constructed in Kahane's seminal paper in 1985 in an attempt to provide a mathematical foundation for Kolmogorov-Obukhov-Mandelbrot theory of energy dissipation in developed turbulence. It has attracted a lot of attentions from the mathematics community in the last decade, playing a pivotal role in the probabilistic formulation of Liouville conformal field theory, as well as showing up in different branches of mathematics such as analytic number theory where it describes the statistical behaviour of the Riemann zeta function on the critical line. This thesis explores the theory of Gaussian multiplicative chaos in three different directions. We commence with a new connection with random matrix theory, showing that for large Hermitian matrices sampled from the one-cut-regular unitary ensemble, the absolute powers of the characteristic polynomial, when suitably normalised, converge in distribution to multiplicative chaos on the support of the limiting spectral distribution as the size of the matrix goes to infinity, and the limit is independent of the choice of the potential function. This is part of an ongoing programme of establishing Gaussian multiplicative chaos as a universal limit object in probability theory. Next, we consider Gaussian multiplicative chaos in the context of Liouville conformal field theory and study the fusion estimate of the Liouville correlation function. More precisely, we derive the exact asymptotics for the Liouville four-point correlation when two points are merging and express the leading order coefficient in terms of DOZZ constants from the three-point correlation function. Our result is consistent with predictions from conformal bootstrap in theoretical physics, and has a geometric interpretation of surfaces being glued together, as hinted by the bootstrap equation. Finally, we study the right tail of the mass of Gaussian multiplicative chaos and establish a formula for the leading order asymptotics under mild assumptions on the underlying log-correlated Gaussian field. The tail exponent satisfies a universal power-law profile, while the leading order coefficient can be described by the product of two constants, one capturing the dependence on the test set and any non-stationarity, and the other one encoding the universal properties of multiplicative chaos. This may be seen as a first step in understanding the full distributional properties of Gaussian multiplicative chaos.

description: The work in this dissertation focused on delivering a nipple shield drug delivery device that is ready for clinical trials with the hope of making a positive impact on the health of neonates, infants, and paediatrics five and younger worldwide. In order to do that, the tools and techniques necessary to understand the hydrodynamics of the system needed to be developed, and then used, to fully grasp the impact of the number of effluent holes, the size and positioning of those effluent holes, and the shape and form factor of the nipple shield and any potential internal geometry contained within. Next, it was essential to understand the landscape of potential use cases for the device, including the populations of neonates, infants and paediatrics five and younger worldwide, but particularly in low- and middle-income countries, where the impact and burden of disease and mortality is highest. This involved collecting and analyzing data on such infant mortality and incidence of disease globally, and then determining and compiling a list of the highest impact medications that could be used within the nipple shield drug delivery device. Finally, it was essential to test real-world impact of the device, so three of the highest impact medications were selected for testing. Tablet dissolution and disintegration was studied using NMR spectroscopy, and a breastfeeding mimic simulation was created to test delivery of the three designated medications within the temporal and volumetric constraints of a single average breastfeeding session. Conclusions based on the results of each set of experiments were drawn, leading to an analysis of the evaluated nipple shield designs and features in preparation for clinical trials.
Search for a W' Boson Decaying to a Top and Bottom Quark Pair in 1.8 TeV p-pbar Collisions

description: We report the results of a search for a W' boson produced in p-pbar collisions at a center-of-mass energy of 1.8 TeV using a 106 pb-1 data sample recorded by the Collider Detector at Fermilab. We observe no significant excess of events above background for a W' boson decaying to a top and bottom quark pair, with the top quark subsequently decaying into a semileptonic final state. These data allow us to set limits on the rate of W' boson production and decay. In a model where this boson would mediate interactions involving a massive right-handed neutrino (nu_R) and has Standard Model strength couplings, we exclude a W' boson with mass between 225 and 536 GeV/c**2 at 95% confidence level for M_W' >> M_nu_R and between 225 and 566 GeV/c**2 at 95% confidence level for M_W' < M_nu_R.

description: Photo-electron spectra obtained with intense pulses generated by free-electron lasers through self-amplified spontaneous emission are intrinsically noisy and vary from shot to shot. We extract the purified spectrum, corresponding to a Fourier-limited pulse, with the help of a deep neural network. It is trained on a huge number of spectra, which was made possible by an extremely efficient propagation of the Schrödinger equation with synthetic Hamilton matrices and random realizations of fluctuating pulses. We show that the trained network is sufficiently generic such that it can purify atomic or molecular spectra, dominated by resonant two- or three-photon ionization, non-linear processes which are particularly sensitive to pulse fluctuations. This is possible without training on those systems.

description: We present the many-particle Hamiltonian model of Lipkin, Meshkov and Glick in the context of deformed polynomial algebras and show that its exact solutions can be easily and naturally obtained within this formalism. The Hamiltonian matrix of each $j$ multiplet can be split into two submatrices associated to two distinct irreps of the deformed algebra. Their invariant subspaces correspond to even and odd numbers of particle-hole excitations.

description: An early and precise diagnosis of disease is a crucial requirement for fast and targeted therapy in the era of precision medicine. Most diseases possess molecular alterations in their early stages, which precede noticeable morphological changes. One important molecular change that contributes to dysfunction in a wide range of pathologies, including cancer and neurological disorders, is an increase in levels of reactive oxygen species (ROS) and associated oxidative damage. Our understanding of how ROS influence disease biology is currently limited by our inability to perform sensitive and specific assessment of ROS levels with high spatial and temporal resolution in living systems. The goal of the research described in this thesis was to overcome the challenge of assessing ROS during disease development in cancer and neurodegenerative disease through the design, synthesis and validation of two classes of novel bifunctional, ROS-sensitive contrast agents. To shed light on the complex redox biology in cancer, the new method of photoacoustic imaging was exploited. A novel activatable, targeted near infrared cyanine dye is reported that enables specific detection of pathological levels of hydrogen peroxide, a major and abundant ROS in living organisms. This approach uses photoacoustic and fluorescence imaging in cancerous tissue to evaluate the performance of the new probe under in vitro and in vivo conditions. In neurodegeneration, there exists a bidirectional interaction between oxidative stress and protein aggregates. To scrutinise this relationship, both bulk and single-molecule fluorescence imaging methods were used to assess the capability of novel bifunctional fluorescence dyes to localise the presence of the two putative disease-causing species, ROS and protein aggregates, simultaneously under in vitro conditions. The data shown here provides a promising foundation for the systematic design of contrast agents based on small molecule dyes, that possess ideal optical and biological characteristics to study oxidative stress in a broad range of pathological applications with high temporal and spatial resolution.

description: ARIADNE is a 1-ton (330 kg fiducial mass) dual-phase liquid argon (LAr) time projection chamber (TPC) featuring a novel optical readout. Four electron-multiplying charge-coupled device (EMCCD) cameras are mounted externally, and these capture the secondary scintillation light produced in the holes of a thick electron gas multiplier (THGEM). Track reconstruction using this novel readout approach is demonstrated. Optical readout has the potential to be a cost effective alternative to charge readout in future LArTPCs. In this paper, the technical design of the detector is detailed. Results of mixed particle detection using a secondary beam from the CERN PS (representing the first ever optical images of argon interactions in a dual-phase LArTPC at a beamline) and cosmic muon detection at the University of Liverpool are also presented.

description: Understanding the interaction between plasmonic nanoparticles and transparent conductive oxides is instrumental to the development of next-generation photovoltaic, opto-electronic and energy-efficient solid-state lighting devices. We investigated the optical response of hybrid media composed of gold nanoparticles deposited on aluminum-doped zinc oxide thin films with varying doping concentration by spectroscopic ellipsometry. The dielectric functions of bare AZO were addressed first, revealing doping-induced effects such as the band-gap shift and the appearance of free carriers. In the hybrid media, a blueshift of the localized surface plasmon resonance of Au NPs as a function of increasing Al-doping of the substrate was observed, ascribed to the occurrence of a charge transfer between the two materials and the doping-dependent variation of the polarizability of the substrate.
Flow fields created by impinging liquid jets and applications in cleaning

description: Cleaning is an essential domestic and industrial operation. It is particularly important in the food and pharmaceuticals sectors, where a large proportion of the total water consumption (as much as 70%) is used just for cleaning. Impinging liquid jets are frequently used for cleaning operations and currently, almost all industrial cleaning systems are based on empirical results. In an effort to develop efficient and sustainable cleaning systems, I have studied the flow field created by impinging liquid jets and their application in cleaning. On impingement of a liquid jet onto a surface, the liquid spreads radially outwards until it reaches a point where the liquid film changes its thickness abruptly. This transition from a thin film to a thick film is demarcated by a hydraulic jump. The supercritical thin film flow is also associated with higher momentum and shear stress, and is therefore, key for cleaning and heat transfer applications. For more than a century, it has been believed that these thin film hydraulic jumps are created due to gravity. However, in this dissertation it is shown both experimentally and theoretically, that these hydraulic jumps result from energy losses due to surface tension and viscous forces alone and gravity plays no significant role. The new theory allow the size of thin film region (location of the hydraulic jump) to be predicted and manipulated. The location where flow in the thin film becomes turbulent is also considered. The average-velocity and the location demarcating the laminar to turbulent transition were measured and showed good agreement with the model. The model for cleaning by normally impinging jets (by peeling mechanism) (Wilson et al., 2014) was then extended to consider cleaning by oblique impinging jets and compared with experimental data which showed a good agreement. Finally, cleaning scenarios arising in industrial systems where the liquid jets moves across a soiled surface were modelled. In these scenarios the liquid jet impinges obliquely and moves with varying velocity. A simple mathematical framework was developed for these systems on which more detailed models can build on.

description: The paper explores the strategies of the wine stakeholders with respect to outsourcing versus integration of the wine-making process by analyzing original and recent data issued from the companies producing wine in Burgundy. Our research question is: Does terroir matter for wine business model between staying viticulturist or becoming winemaker? We investigate this question within the mosaic of the Burgundian vineyard. A Principal Components Analysis highlights the latent variables explaining the different strategies of stakeholders in Burgundy, and a cluster analysis tries at identifying the differences existing between the winegrowers, with a special focus on the viticulturists and the winemakers. The results show that the strategies of the Burgundian wine stakeholders with respect to outsourcing vs. integration differ according to the level of Appellation d’Origine. Consequently the terroir operates as discriminant factor between outsourcing whether integrating some, if not all, of the stages of the wine-making process, including sales. Each sub-region of the Burgundian vineyard has a specific business model strongly related to the territory nesting the wine estates.

description: The study examines the problem of using augmented and virtual reality in the process of blended learning in general secondary education. The study analyzes the meaning of the concept of "blended learning". The conceptual principles of blended learning are considered. The definition of augmented and virtual reality is given. The mixed reality is considered as a separate kind of notion. Separate applications of virtual and augmented reality that can be used in the process of blended learning are considered. As a result of the study, the authors propose possible ways to use augmented reality in the educational process. The model of using augmented and virtual reality in blended learning in general secondary education institutions was designed. It consists of the following blocks: goal; teacher's activity; forms of education; teaching methods; teaching aids; organizational forms of education; pupil activity and results. Based on the model, the methodology of using augmented and virtual reality in blended learning in general secondary education was developed. The methodology contains the following components: target component, content component, technological component and resultant component. The methodology is quite universal and can be used for any subject in general secondary education. The types of lessons in which it is expedient to use augmented (AR) and virtual reality(VR) are determined. Recommendations are given at which stage of the lesson it is better to use AR and VR tools (depending on the type of lesson).

description: We present the photometric properties of 1279 blue variable stars within the LMC. Photometry is derived from the MACHO database. The lightcurves of the sample exhibit a variety of quasi-periodic and aperiodic outburst behavior. A characteristic feature of the photometric variation is that the objects are reddest when at maximum outburst. A subset of 102 objects were examined spectroscopically. Within this subset, 91% exhibited Balmer emission in at least one epoch, in some cases with spectacular spectral variability. The variability observed in the sample is consistent with the establishment and maintenance of the Be phenomenon.

description: I study various properties of the critical limits of correlators containing insertions of conserved and anomalous currents. In particular, I show that the improvement term of the stress tensor can be fixed unambiguously, studying the RG interpolation between the UV and IR limits. The removal of the improvement ambiguity is encoded in a variational principle, which makes use of sum rules for the trace anomalies a and a'. Compatible results follow from the analysis of the RG equations. I perform a number of self-consistency checks and discuss the issues in a large set of theories.

description: The effect of Rashba spin-orbit interaction and anisotropic strain on the electronic, optical and thermodynamic properties of artificial graphene-like superlattice composed of InAs-GaAs quantum dots has been considered theoretically. The electronic energy dispersions have been obtained using Green's function formalism in combination with Fourier transformation to the reciprocal space and an exact diagonalization technique. We have observed a splitting of Dirac points and appearance of edditional Dirac-like points due to the Rashba spin-orbit interaction. Breaking of the hexagonal symmetry of the dispersion surfaces caused by the strain anisotropy is observed as well. It is shown that both the spin-orbit interaction and strain anisotropy have a qualitative impact on the measurable characteristics of the considered structure and can be used as effective tools to control the performance of devices based on artificial graphene.

description: We demonstrate a class of optimum detection strategies for extracting the maximum information from sets of equiprobable real symmetric qubit states of a single photon. These optimum strategies have been predicted by Sasaki et al. [Phys. Rev. A{\bf 59}, 3325 (1999)]. The peculiar aspect is that the detections with at least three outputs suffice for optimum extraction of information regardless of the number of signal elements. The cases of ternary (or trine), quinary, and septenary polarization signals are studied where a standard von Neumann detection (a projection onto a binary orthogonal basis) fails to access the maximum information. Our experiments demonstrate that it is possible with present technologies to attain about 96% of the theoretical limit.

description: The ‘mechanical arts’ or artes mechanicae were first named as a part of Philosophy in Hugh of Saint-Victor’s Didascalicon (1120s). They were identified as seven arts (fabric making, armament, commerce, agriculture, hunting, medicine, and theatrics), and positioned as a parallel to the seven liberal arts. Their inclusion in the Didascalicon has been taken by previous historians to signal a new interest in science and engineering, an effort to ‘give intellectual status to technology for the first time’. This study reconsiders the significance of the mechanical arts for schoolmen working in northern France in the twelfth century. It argues that while this category designated a set of everyday technologies, it also had a more covert, imaginative currency for certain authors – as an image or exemplum for the process of learning. Its procedures and activities could be held up as a mirror to those of the liberal and especially verbal arts, picturing these in the terms of poiesis – an ancient model for philosophy as ‘sense making’ or ‘world making’. This metaphorical utility of the artes mechanicae can be discerned in Hugh’s discussion, running underneath his more literal concern with the mechanical arts as everyday technologies. It was given fullest expression, I argue, in the later allegorical encyclopaedias of ‘Chartrian’ poets, Bernard Silvestris and Alan of Lille (1140s–80s). The final part of the thesis discusses Geoffrey of Vinsauf’s Poetria nova (c. 1215). Here the mechanical arts are enlisted to represent the student of the verbal arts as a technite, a technician and theorist. Geoffrey’s work is often considered a summa of medieval thinking about poet-craft. But its recruitment of the mechanical arts to picture theoretical mastery also marks the end – and a reversal – of the lesser-known invocation of mechanica by twelfth-century authors, the one I trace here: which cast the author and scholar as a maker proper, a ‘poet’ in the ancient sense of that word.

Cereal Price Transmission in Several Large Asian Countries during the Global Food Crisis

description: World cereal prices have been increasing substantially since 2003. Until 2008, the Asian countries examined in this paper (Bangladesh, China, India, Indonesia, the Philippines, Thailand and Viet Nam) had generally been able to contain domestic price increases by using trade policies and taking advantage of the depreciation of the US dollar. On average, domestic price increases in real terms were only about one third of the world price increases in real US dollar terms. In the face of large world price increases in early 2008, the transmission to domestic markets was still incomplete, but prices increased substantially in some countries. In other countries, however, prices increased very little, if at all. Trade policies explain some of the different outcomes across countries, but speculative activity by farmers, traders, and consumers also appears to have played a role. While there has been incomplete transmission between world and domestic markets, transmission within national borders has been stronger in the sense that, for any given country, percentage increases in farm and consumer prices have been similar. The overall price increases during the past several years have probably been large enough to create a supply response, even in the face of higher fertilizer prices.

Such a CFT is obtained by m-reduction on the one layer system, with a resulting pairing symmetry and presence of quasi-holes. For the m=2 case boundary terms are shown to describe an impurity interaction which allows for a localized tunnel of the Kondo problem type. The presence of an anomalous fixed point is evidenced at finite coupling which is unstable with respect to unbalance and flows to a vacuum state with no quasi-holes.

The extent of market integration is determined by identifying locations that are linked by trade and whose prices share the same long-run relationship. The method of estimating the permanent component is applied to examine the importance of markets in shaping the long-run rice price. The pattern and degree of integration are assessed by testing for the existence of the law of one price (LOP) and ascertaining the speed of adjustment toward long-run equilibrium, using various tests in the cointegrated system. Results show that only nine of 34 rice markets are integrated into a common rice market. However, prices are transmitted well among the integrated rice markets. The supply of rice appears to be the most important factor shaping the long-run behavior of its price levels in Vietnam. No single market is found to be the price leader. The prices of rice exported by Vietnam and Thailand are cointegrated and conform to LOP. The removal of the export quota plays an insignificant role in determining the relationship of rice prices in the two countries. The study suggests improving the extent of domestic rice market integration by focusing on the development of roads, communication and other market-related infrastructure, and instituting food policy reforms in the supply regions, while directly targeting the poor and mountainous areas. To improve the export price and become more active in the world rice market, Vietnam should (1) adopt modern postharvest technologies and develop better rice varieties, (2) develop an integrated rice marketing chain from farmers to exporters, (3) enhance the capacity to undertake rice market analysis and forecast, (4) encourage rice-exporting enterprises to follow certain rules to avoid cut-throat competition, and (5) establish a system of rice standards and create a trade mark for Vietnamese rice.

description: The transmission of mosquito-borne Chikungunya virus (CHIKV) has large epidemics worldwide. Till date, there are neither anti-viral drugs nor vaccines available for the treatment of Chikungunya. Accumulated evidences suggest that some natural compounds i.e., Epigallocatechin gallate, Harringtonine, Apigenin, Chrysin, Silybin, etc. have the capability to inhibit CHIKV replication in vitro. Natural compounds are known to possess less or no side effects. Therefore, natural compound in its purified or crude extracts form could be the preeminent and safe mode of therapies for Chikungunya. Wet lab screening and identification of natural compounds against Chikungunya targets is a time consuming and expensive exercise. In the present study, we used in silico techniques like receptor-ligand docking, Molecular dynamic (MD), Three Dimensional Quantitative Structure Activity Relation (3D-QSAR) and ADME properties to screen out potential compounds. Aim of the study is to identify potential lead/s from natural sources using in silico techniques that can be developed as a drug like molecule against Chikungunya infection and replication. Three softwares were used for molecular docking studies. Potential ligands selected by docking studies were subsequently subjected 3D-QSAR studies to predict biological activity. Based on docking scores and pIC50 value, potential anti-Chikungunya compounds were identified. Best docked receptor-ligands were also subjected to MD for more accurate estimation. Lipinski’s rule and ADME studies of the identified compounds were also studied to assess their drug likeness properties. Results of in silico findings, led to identification of few best fit compounds of natural origin against targets of Chikungunya virus which may lead to discovery of new drugs for Chikungunya.

description: We suggest that Jovian planets will survive the late stages of stellar evolution, and that white dwarfs will retain planetary systems in wide orbits (>5AU). Utilising evolutionary models for Jovian planets, we show that infra-red imaging with 8m class telescopes of suitable nearby white dwarfs should allow us to resolve and detect companions >3Mjup. Detection of massive planetary companions to nearby white dwarfs would prove that such objects can survive the final stages of stellar evolution, place constraints on the frequency of main sequence stars with planetary systems dynamically similar to our own and allow direct spectroscopic investigation of their composition and structure.

Food Consumption/Nutrition/Food Safety

description: This study investigates the relationship between social capital and local food movements in rural Japan, with the latter factor markedly leaning towards the goal, “Local Production for Local Consumption” (LPLC). Promoted by the central and local governments in Japan since the 1990s, LPLC was envisioned to increase food self-sufficiency, revitalize rural communities, address consumers’ food safety concerns, and provide food education. A structured interview survey is conducted on 56 agricultural communities in Chiba Prefecture, Japan. The social capital indicators used represent both the structural and cognitive types of social capital. The scores measuring the level of social capital are compared against the presence or absence of LPLC activity in the household. The data collected yield several important findings. First, structural social capital at the community level contributes to both profit-oriented activities and socially oriented voluntary community activities. Second, structural social capital at the household level affects LPLC activities in various ways. The higher the farmers’ level of participation in local social groups, the more actively they sell their products at farmers’ markets. In contrast, the personal networks of those farmers who run agritourism tend to be limited within the same communities. Third, cognitive social capital at the household level indicates no particular relevance with LPLC activities.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

Time-Dependent Photoionization in a Dusty Medium I: Code Description and General Results

description: We present a time-dependent photoionization code that combines self-consistently metal evolution and dust destruction under an intense X-ray UV radiation field. Firstly, we extend the mathematical formulation of the time-dependent evolution of dust grains under an intense radiation flux with the inclusion of the process of ion field emission (IFE). We determine the relative importance of IFE with respect to X-ray and UV sublimation as a function of grain size, intensity and hardness of the incident spectrum. We then combine the processes of dust destruction with a photoionization code that follows the evolution of the ionization states of the metals and the relative radiative transitions. Our code treats, self-consistently, the gradual recycling of metals into gas as dust is sublimated away; it allows for any initial dust grain distribution and follows its evolution in space and time. In this first paper, we use our code to study the time-dependent behaviour of the X-ray and optical opacities in the nearby environment of a Gamma-ray Burst, and show how the time variability of the low-energy and high-energy opacities can yield powerful clues on the characteristics of the medium in which the bursts occur.

description: In this paper we shall investigate the possibility of solving U(1) theories on the non-commutative (NC) plane for arbitrary values of $θ$ by exploiting Morita equivalence. This duality maps the NC U(1) on the two-torus with a rational parameter $θ$ to the standard U(N) theory in the presence of a 't Hooft flux, whose solution is completely known. Thus, assuming a smooth dependence on $θ$, we are able to construct a series rational approximants of the original theory, which is finally reached by taking the large $N-$limit at fixed 't Hooft flux. As we shall see, this procedure hides some subletities since the approach of $N$ to infinity is linked to the shrinking of the commutative two-torus to zero-size. The volume of NC torus instead diverges and it provides a natural cut-off for some intermediate steps of our computation. In this limit, we shall compute both the partition function and the correlator of two Wilson lines. A remarkable fact is that the configurations, providing a finite action in this limit, are in correspondence with the non-commutative solitons (fluxons) found independently by Polychronakos and by Gross and Nekrasov, through a direct computation on the plane.
