description: Odours released by objects in natural environments can contain information about their spatial locations. In particular, the correlation of odour concentration timeseries produced by two spatially separated sources contains information about the distance between the sources. For example, mice are able to distinguish correlated and anti-correlated odour fluctuations at frequencies up to 40 Hz, while insect olfactory receptor neurons can resolve fluctuations exceeding 100 Hz. Can this high-frequency acuity support odour source localization? Here we answer this question by quantifying the spatial information about source separation contained in the spectral constituents of correlations. We used computational fluid dynamics simulations of multisource plumes in two-dimensional chaotic flow environments to generate temporally complex, covarying odour concentration fields. By relating the correlation of these fields to the spectral decompositions of the associated odour concentration timeseries, and making simplifying assumptions about the statistics of these decompositions, we derived analytic expressions for the Fisher information contained in the spectral components of the correlations about source separation. We computed the Fisher information for a broad range of frequencies and source separations for three different source arrangements and found that high frequencies were more informative than low frequencies when sources were close relative to the sizes of the large eddies in the flow. We observed a qualitatively similar effect in an independent set of simulations with different geometry, but not for surrogate data with a similar power spectrum to our simulations but in which all frequencies were a priori equally informative. Our work suggests that the high-frequency acuity of olfactory systems may support high-resolution spatial localization of odour sources. We also provide a model of the distribution of the spectral components of correlations that is accurate over a broad range of frequencies and source separations. More broadly, our work establishes an approach for the quantification of the spatial information in odour concentration timeseries.

description: Finite time correlations of the velocity in a surface flow are found to be important for the formation of clusters of Lagrangian tracers. The degree of clustering characterized by the Lyapunov spectrum of the flow is numerically shown to be in qualitative agreement with the predictions for the white-in-time compressible Kraichnan flow, but to deviate quantitatively. For intermediate values of compressibility the clustering is surprisingly weakened by time correlations.

title: Intermedial anatomy: nineteenth century literature and collections culture through the Cole Library of early medicine and zoology
Creators: name: Burke, Verity
Publisher: name: University of Reading
Year: 2018

description: This thesis takes the concept of anatomical intermediality, defined as the organic interactions between the media used in the display of museum specimens, as one of its central concerns. The project uses the Cole Library of Early Medicine and Zoology, at the University of Reading, to consider the way in which nineteenth-century anatomy museums and their objects were interpreted through their surrounding media. In particular, it examines the dialogue between museums and literature, focusing on how anatomical institutions borrowed literary techniques to legitimize their objects and to enhance their respectability; plus how literature incorporated curatorial techniques such as ordering and interpretation to demonstrate how the body was a complex and vital source of knowledge. This thesis employs the ‘zoobibliophile’ approach of the library’s collector, Professor Francis J. Cole (1872-1959), to consider how a thorough knowledge of bodies and books can inform our approaches and our comprehension of both. Using this methodology, the project uses Cole’s own work and the holdings in his library to create ‘border cases’ – specifically, a museum or type of specimen that provides insight into wider cultural issues – to reveal the dialogue between literature, the case study and its contexts. These border cases use the library’s holdings to move through various institutions which were troubled by anxieties about the propriety of display, and the bodies they present, including: the Hunterian in the Royal College of Surgeons, London, and its representation in Household Words; the publications issued by the now defunct Kahn’s Museum of Anatomy and Pathology, London, and the representation of the body in Wilkie Collins’s The Law and the Lady (1875); nineteenth-century taxidermy guides and the taxidermised body in Charles Dickens’s Our Mutual Friend (1864-65).

title: After the law: towards judicial-visual activism
Creators: name: Feldman, Avi
Publisher: name: University of Reading
Year: 2018

description: Law and art are oftentimes perceived as standing in opposition, and even seen in conflicting terms. The first is dismissed as provincial, rigid, and bureaucratic, while the latter is repeatedly characterized as global, flexible, and dynamic. Yet, closer observation and analysis reveal hidden links and layers, and substantial preoccupation by both legal and art practitioners in the visual and in the judicial. It is through the unraveling of spaces, gaps, and lacunae in which both fields of practice and knowledge intersect that this publication sets in motion an exploration of influences and interactions between law and art. Offering a new critical approach and methodology to deal with existing and imagined relations between law and art, this publication analyzes curatorial and artistic projects by revealing overlooked legal dimensions embedded within them. It introduces legal theory and scholarship in relation to visual artworks in order to expand and foster new paths for both judicial and visual activism. Based on the reassessment of artistic and curatorial capabilities and encounters in a time of globalization, it is concerned with broadening our perception of the role of art and legal practitioners with regard to justice. Following an introduction of Nancy Fraser's three-dimensional concept of justice, and Saskia Sassen's notion of capabilities in a world shaped by the dual existence of the nation-state and globalization, Chapter One focuses on the 7th Berlin Biennale as a curatorial case study for political and artistic activism, and on “Artist Organisations International” (AOI) as an example of artist-created institutions concerned with political activism. Two artistic projects that premiered during the 7th Berlin Biennale are then critically examined in Chapters Two and Three. An in-depth exploration of Yael Bartana's First Congress of The Jewish Renaissance Movement in Poland (JRMiP) as a space prompting global justice is the focus of Chapter Two. The building of a Parliament in Rojava by Jonas Staal's New World Summit (NWS) as an artistic reinvention of the Right of Intervention is the concern of Chapter Three. Judicial-visual activism is further developed in Chapter Four through an inquiry into the theory of the emergence of disputes, and the Right of the Encounter in relation to artistic actions taking place in state institutions. Chapter Five contains a reflection on my own recent curatorial projects dedicated to encounters that I facilitated between legal and art practitioners. The result of these encounters led to the exhibition Motions for the Agenda structured around five motions/projects developed in a collaboration between the participants dealing with legal texts and documents, just as with the place of law, its language, and its archive.

description: We extend our previous work on shot noise for entangled and spin polarized electrons in a beam-splitter geometry with spin-orbit (\textit{s-o}) interaction in one of the incoming leads (lead 1). Besides accounting for both the Dresselhaus and the Rashba spin-orbit terms, we present general formulas for the shot noise of singlet and triplets states derived within the scattering approach. We determine the full scattering matrix of the system for the case of leads with \textit{two} orbital channels coupled via weak \textit{s-o} interactions inducing channel anticrossings. We show that this interband coupling coherently transfers electrons between the channels and gives rise to an additional modulation angle -- dependent on both the Rashba and Dresselhaus interaction strengths -- which allows for further independent coherent control of the electrons traversing the incoming leads. We derive explicit shot noise formulas for a variety of correlated pairs (e.g., Bell states) and lead spin polarizations. Interestingly, the singlet and \textit{each} of the triplets defined along the quantization axis perpendicular to lead 1 (with the local \textit{s-o} interaction) and in the plane of the beam splitter display distinctive shot noise for injection energies near the channel anticrossings; hence, one can tell apart all the triplets, in addition to the singlet, through noise measurements. We also find that spin-orbit induced backscattering within lead 1 reduces the visibility of the noise oscillations, due to the additional partition noise in this lead. Finally, we consider injection of two-particle wavepackets into leads with multiple discrete states and find that two-particle entanglement can still be observed via noise bunching and antibunching.

description: The quest for non-Abelian quasiparticles has inspired decades of experimental and theoretical efforts, where the scarcity of direct probes poses a key challenge. Among their clearest signatures is a thermal Hall conductance with quantized half-integer value in natural units $ π^2 k_B^2 T /3 h$ ($T$ is temperature, $h$ the Planck constant, $k_B$ the Boltzmann constant). Such a value was indeed recently observed in a quantum-Hall system and a magnetic insulator. We show that a non-topological "thermal metal" phase that forms due to quenched disorder may disguise as a non-Abelian phase by well approximating the trademark quantized thermal Hall response. Remarkably, the quantization here improves with temperature, in contrast to fully gapped systems. We provide numerical evidence for this effect and discuss its possible implications for the aforementioned experiments.

The transformation of "Tam Lin" : an analysis of folktale picture books
Creators: name: Mullen, Ginger
Publisher: name: University of British Columbia
Year: 2009

description: The folktale picture book is rooted in a common folklore as well as literary and illustrative traditions. Scholarship indicates the necessity for evaluative criteria to be proposed for this unique genre which, subsequently, would assist writers, illustrators, critics and, due to their dependence on written retellings, storytellers. I group critical questions stemming from the adaptation a folktale to a folktale picture book into four categories. The first source acknowledgement, asks whether an author has credited folktale sources used when researching the retelling. The second, narrative features, examines changes made to a folktale's plot, characters and setting. The third, stylistic features, looks at the techniques by which a folktale works as an oral story and asks if the folktale picture book also lends itself to oral performance, preserves recurring symbols and images, and effectively uses diction. The final category, illustrative features, explores the ways in which an artist incorporates folklore into the pictures by means of mirroring the text, accurately presenting the culture, bringing additional layers of meaning to the story, and respecting the folkloric text's presence on the page. I apply these questions to four picture books which maintain dominant motifs found in nine versions of the ballad of "Tam Lin" collected by Sir Frances Child: "Tamlane" by Judy Paterson and Sally J. Collins, "The Enchanted Forest" by Rosalind Kervan and Alan Marks, Tarn Lin by Susan Cooper and Warwick Hutton, and "Tam Lin" by Jane Yolen and Charles Mikolaycak. This analysis leads me to conclude that, around a base of source materials, the narrative, stylistic and illustrative categories that form my evaluative framework converge to form a metaphorical triangle; a good folktale picture book must be constructed from these equally important foundations; serious deficiency in one area affects the structural integrity of the entire book. On a more personal level, this investigation has prompted me to re-examine my own work as an oral storyteller. My version of "Tam Lin," ever a work in progress, has been changed by this evaluative framework as well as my experience with the picture books themselves.

description: Information on the value of water in use is a prerequisite for the efficient allocation, utilization, trading and transfer thereof. These issues are becoming very important for South Africa. Linear programming (LP) and stochastic dynamic programming (SDP) are two techniques that can be applied to value water. Based on a simulated irrigation farming situation downstream of the Vanderkloof Dam wherein farmers hold a capacity share (CS) this paper draws a comparison between the marginal value products (MVP’s) obtained from applying LP and SDP simultaneously. Linear programming is used to optimize water use on the farm during the immediate season while SDP is used to optimize the use of water in storage in the farmers capacity share (CS) in the Vanderkloof Dam through time. Emphasis is placed on the interpretation of the results which are presented graphically.

description: We report on a multiwavelength campaign on the TeV gamma-ray blazar Markarian (Mrk) 421 performed during December 2002 and January 2003. These target of opportunity observations were initiated by the detection of X-ray and TeV gamma-ray flares with the All Sky Monitor (ASM) on board the Rossi X-ray Timing Explorer (RXTE) and the 10 m Whipple gamma-ray telescope.The campaign included observational coverage in the radio (University of Michigan Radio Astronomy Observatory), optical (Boltwood, La Palma KVA 0.6m, WIYN 0.9m), X-ray (RXTE pointed telescopes), and TeV gamma-ray (Whipple and HEGRA) bands. At TeV energies, the observations revealed several flares at intermediate flux levels, peaking between 1 and 1.5 times the flux from the Crab Nebula. While the time averaged spectrum can be fitted with a single power law of photon index Gamma =2.8, we find some evidence for spectral variability. Confirming earlier results, the campaign reveals a rather loose correlation between the X-ray and TeV gamma-ray fluxes. In one case, a very strong X-ray flare is not accompanied by a comparable TeV gamma-ray flare. Although the source flux was variable in the optical and radio bands, the sparse sampling of the optical and radio light curves does not allow us to study the correlation properties in detail. We present a simple analysis of the data with a synchrotron-self Compton model, emphasizing that models with very high Doppler factors and low magnetic fields can describe the data.

description: South Africa is entering a whole new era in water management. In the face of efforts to curtail runaway government spending and protect the environment, water institutions must foster the conservation and efficient allocation of existing supplies. They must also take water's growing recreational and environmental value into account. The crucial question is, can the current water institutions meet today's requirements? Despite the resulting inefficiency and waste, traditional resource economists continue to identify taxes, regulations, subsidies, and governmental allocation as solutions to today's water problems. Internationally, there is enough evidence to prove that central allocation with almost any resource gave rise to gross inefficiency. The main reason is the distortions on the value placed on resources within such a centralised planning environment. Resources are either valued to high or to low. What is the value of freshwater and how can water be allocated in such a way as to reflect the scarcity value of water? A non-linear spatial equilibrium model was developed to simulate the impact of a potential water market in the Upper-Berg River: Western Cape. This paper explores water markets as an alternative to central water allocation decisions

Pleasure provides the motivation for intentional agency (Husserl’s Streben), and is viewed, in a more general ethical framework, as an emancipating principle, capable of freeing further pleasure: this allows a reworking of value itself, conceived of as the object intended in action.

description: This paper examines biased technical change in South African agriculture using a system of share equations with unobserved components. Developing on the work of Lambert and Shonkwiler (1995), this paper generalises previous work by introducing independent unobserved components into each model using a regression-based approach. We find evidence of stochastic technical change, which is itself biased between the four factors of production: machinery, land, labour and fertiliser, and which closely reflects distinct phases of South African agricultural policy and development.

description: We present the detailed study of the thermodynamics of vibrational modes in disordered elastic systems such as the Bragg glass phase of lattices pinned by quenched impurities. Our study and our results are valid within the (mean field) replica Gaussian variational method. We obtain an expression for the internal energy in the quantum regime as a function of the saddle point solution, which is then expanded in powers of $\hbar$ at low temperature $T$. In the calculation of the specific heat $C_v$ a non trivial cancellation of the term linear in $T$ occurs, explicitly checked to second order in $\hbar$. The final result is $C_v \propto T^3$ at low temperatures in dimension three and two. The prefactor is controlled by the pinning length. This result is discussed in connection with other analytical or numerical studies.

description: After the deregulation of the South-African agricultural marketing boards, producers are responsible for their own marketing. Various marketing options emerged due to the new marketing environment and the producer needs to take a lot of information into account in order to make the correct marketing decisions. Ample literature exists on the advantages that marketing plans can provide for the producer such as the reduction of price and income risks. Productions cost forms an integrated part of a marketing plan and helps the producer to fix prices in order to run a profitable business. The model that has been developed enhances the producer to develop an optimal crop choice and marketing strategy, given his own unique situation as well as the characteristics of his farm business. The model, for example, takes into account production costs, available marketing funds and cultivation restrictions to develop a strategy that can ensure a reasonable profit per hectare.

Creators: name: Guarducci, Guido
Publisher: name: University of Reading
Year: 2018

description: The first part of the study presented in this volume analyses the material culture, in particular the architecture and pottery production, of the Late Bronze Age and Early Iron Age social groups belonging to a very extensive area that the Assyrian texts referred to as 'Nairi lands: The Nairi lands roughly encompassed Eastern Anatolia, the South Caucasus and North-western Iran. The second part of the study, based on the literature and the new data presented in the first part, furnishes a reassessment of the pottery production characteristics and theories, one of the main identity markers, as well as of the socio-economic structure and issues, tied to the sedentary and mobile local communities of the Nairi lands. The analysis and reassessment processes are fundamental steps for achieving the final objective of this research, establishing a reliable identity profile of the local communities of the Nairi lands. More specifically, the study brings into focus the characteristics, the extension and the distribution of Grooved pottery, the guide fossil for these period, along with other pottery typologies, by providing a Catalogue with detailed descriptions and high-resolution images of the pots and sherds obtained from public and private institutions in Turkey and Armenia. Moreover, the socio-political organization and subsistence economy issues are address in order to advance a possible reconstruction of the social structure of the Nairi lands communities. Particular attention is devoted to the pastoral nomad component and the role played within the Nairi phenomenon. The last part of the study, in appendix, is devoted to the presentation of the results of the archaeometric analyses delivered by the University of Pisa, the Centre for National Research of Pisa and the University of Valencia on a selection of potsherds collected from key sites in the main areas of research.

description: Transferring the motion style from one animation clip to another, while preserving the motion content of the latter, has been a long-standing problem in character animation. Most existing data-driven approaches are supervised and rely on paired data, where motions with the same content are performed in different styles. In addition, these approaches are limited to transfer of styles that were seen during training. In this paper, we present a novel data-driven framework for motion style transfer, which learns from an unpaired collection of motions with style labels, and enables transferring motion styles not observed during training. Furthermore, our framework is able to extract motion styles directly from videos, bypassing 3D reconstruction, and apply them to the 3D input motion. Our style transfer network encodes motions into two latent codes, for content and for style, each of which plays a different role in the decoding (synthesis) process. While the content code is decoded into the output motion by several temporal convolutional layers, the style code modifies deep features via temporally invariant adaptive instance normalization (AdaIN). Moreover, while the content code is encoded from 3D joint rotations, we learn a common embedding for style from either 3D or 2D joint positions, enabling style extraction from videos. Our results are comparable to the state-of-the-art, despite not requiring paired training data, and outperform other methods when transferring previously unseen styles. To our knowledge, we are the first to demonstrate style transfer directly from videos to 3D animations - an ability which enables one to extend the set of style examples far beyond motions captured by MoCap systems.

description: We perform a systematic reanalysis of the age distribution of Galactic open star clusters. Using a catalogue of homogeneously determined ages for 834 open clusters contained in a 2 kpc cylinder around the Sun and characterised with astrometric and photometric data from the Gaia satellite, we find that it is necessary to revise earlier works that relied on data from the Milky Way Star Cluster survey. After establishing age-dependent completeness limits for our sample, we find that the cluster age function in the range $6.5 < \log t<10$ is compatible with a Schechter-type or broken power-law function, whose parameters we determine by MCMC fitting. Our best-fit values indicate an earlier drop of the age function (by a factor of $2-3$) with respect to the results obtained in the last five years, and are instead more compatible with results obtained in the early 2000s and radio observations of inner-disc clusters. Furthermore, we find a typical destruction time-scale of $\sim1.5$ Gyr for a $10^4\, {\rm M}_{\odot}$ cluster and a present-day cluster-formation rate of $0.55_{-0.15}^{+0.19}$ Myr$^{-1}$kpc$^{-2}$, suggesting that only $16_{-8}^{+11}$ \% of all stars born in the solar neighbourhood form in bound clusters. Accurate cluster-mass measurements are now needed to place more precise constraints on open-cluster formation and evolution models.

description: This paper develops a two-sector growth model incorporating the essential distinguishing features of agriculture, including the reliance of production on a natural resource base as well as on industrially produced inputs, the low income elasticity of demand for food and the life-sustaining function of food consumption. In this framework, the ability of an economy to supply an adequate supply of food to a growing population can be related to the existence of a steady state. This property is used to define a simple analytical criterion upon which to assess the long-term food situation of a closed economy. This sustainability condition relates all the dynamic parameters of the economy: rates of technological change in the two sectors, rate of population growth and rate of land degradation. The condition is used to highlight the technological characteristics in agriculture conducive to sustainability and to assess empirically the food situation of a number of countries. Although no global food crisis appears to be looming ahead, the data suggest that sub-Saharan Africa is likely to increase its food dependence in the future.

description: The packing mechanisms between Janus-MoSSe and Aluminum-Nitride (AlN) sheets were systematically investigated by using Density Function Theory calculations. Results show that the stabilization (packing) energies vary from -35.5 up to -17.5 meV depending on the chemical species involved in the interface. The packing energies were obtained using the improved Lennard-Jones (ILJ) potential. The SeMoS/AlN heterostructures, when the MoS face is interacting with the AlN sheet, presented the lowest packing energies due to the sulfur's higher degree of reactivity. Importantly, the calculated bandgap values ranged within the interval 1.61-1.87 eV, which can be interesting for photovoltaic applications.

description: The issue of the possible presence or absence of jets in GRBs is here re-examined for GRB991216. We compare and contrast our theoretically predicted afterglow luminosity in the 2-10 keV band for spherically symmetric versus jetted emission. At these wavelenghts the jetted emission can be excluded and data analysis confirms spherical symmetry. These theoretical fits are expected to be improved by the forthcoming data of the Swift mission.

Essays in oligopoly theory
Creators: name: Dragan, Nicolae Gabriel
Publisher: name: University of British Columbia
Year: 2009

description: This thesis comprises three essays that analyze some strategic interactions of firms in an oligopolistic setting. The first essay examines the strategic role of partial commitments. Allowing firms to deviate from their announcements at some cost relaxes the usual assumption of irrevocable commitments. Such flexible commitments are shown to increase competition and welfare when the firms' actions are strategic substitutes (quantities), but to facilitate collusion and decrease welfare when they are strategic complements (prices). Assuming flexibility to be purely of a technological nature, the model is extended to allow firms to choose between two technologies characterized by different marginal costs of production and flexibilities. With strategic substitutes, adoption of an inflexible and cost-inefficient technology can lead to increased competition and welfare. The second essay investigates the role of capacities in sustaining collusion in a repeated game. It is shown that collusion can be supported by choosing insufficient capacities if ex ante identical firms tacitly agree to produce the same output regardless of their ex post capacities. This type of self-enforcing agreement removes the rent-seeking consequences of the usual type of tacit agreements used in the literature. An exogenous increase in the discount factor is shown to possibly increase welfare by improving the cost-efficiency of firms. An exogenous increase in the number of firms may lead to an increase in the cost-inefficiency of firms and, therefore, it may decrease welfare. The last essay examines the effect of entry in one regional market on the structure and competition in another regional market that interacts with the first one through a firm (a national firm) that operates in both markets. If entry changes the national firm's profitability of undertaking activities that reduce its marginal cost, possible entry in one regional market will impinge on the profitability of the firm in the other regional market. It is shown that entry in one market can either intensify or reduce competition in the other regional market. One surprising result is that an attempt by government to subsidize entry in one market may motivate the national firm to deter entry in both markets, but this does not necessarily reduce welfare.

Two-fluid hydrodynamic modes in a trapped superfluid gas

description: In the collisional region at finite temperatures, the collective modes of superfluids are described by the Landau two-fluid hydrodynamic equations. This region can now be probed over the entire BCS-BEC crossover in trapped Fermi superfluids with a Feshbach resonance, including the unitarity region. Building on the approach initiated by Zaremba, Nikuni, and Griffin in 1999 for trapped atomic Bose gases, we present a new variational formulation of two-fluid hydrodynamic collective modes based on the work of Zilsel in 1950 developed for superfluid helium. Assuming a simple variational ansatz for the superfluid and normal fluid velocities, the frequencies of the hydrodynamic modes are given by solutions of coupled algebraic equations, with constants only involving spatial integrals over various equilibrium thermodynamic derivatives. This variational approach is both simpler and more physical than a direct attempt to solve the Landau two-fluid differential equations. Our two-fluid results are shown to reduce to those of Pitaevskii and Stringari for a pure superfluid at T=0.
