title: "Only the rames of a man": Investigating Masculinities in the Novels of Thomas Hardy.
Creators: name: Hayes, Tracy L.
Publisher: name: The Open University
Year: 2017

description: The aim of this thesis is to illustrate the fluid and evolving nature of masculinities as experienced and articulated by Victorian men, and then to examine critically Hardy's representations of such across his novelistic oeuvre in order to identify how his representations differed from, challenged, or subverted those of his contemporaries. Representations of character are analysed in terms of gendering, and rather than basing my readings of Hardy's characters on hetero-normative constructions of nineteenth-century masculinity, I identify and argue for new discursive categories of Victorian masculinity while engaging with social, psycho-sexual and evolutionary/biological constructions of maleness throughout the century. The first chapter establishes a variety of necessary cultural, scientific and social contexts against which Hardy's projections of masculinity can be interpreted. The second chapter comprises a literature review of extant gender criticism addressed to the Hardy corpus, engaging with various approaches and interpretations while demonstrating the extent to which my own readings differ from the critics selected. Chapter three concentrates upon the figure of the Alpha-male as perceived within the social and evolutionary discourses of the nineteenth century, analysing the discursive categories of the lover, the soldier and the androgyne as they appear in both Hardy's fiction and that of his contemporaries. Chapter four identifies the discursive categories of the male as 'other', the 'unman', and the 'man-girl', and their narrative functions within the textual parameters they each occupy. The fifth chapter investigates representations of misogyny and the homosocial, chapter six explores male psychological instability, and the final chapter discusses the concepts of empathy and Stoicism as understood within Victorian society, and how they influence representations of the New Man in Hardy's novels. I conclude by identifying further possible avenues for investigation with regards to Hardy's oeuvre, including how his male characters are portrayed on film, or delineated within his poetry and short stories.

description: We study Susceptible-Exposed-Asymptomatic-Infectious-Recovered (SEAIR) epidemic spreading model of COVID-19. It captures two important characteristics of the infectiousness of COVID-19: delayed start and its appearance before onset of symptoms, or even with total absence of them. The model is theoretically analyzed in continuous-time compartmental version and discrete-time version on random regular graphs and complex networks. We show analytically that there are relationships between the epidemic thresholds and the equations for the susceptible populations at the endemic equilibrium in all three versions, which hold when the epidemic is weak. We provide theoretical arguments that eigenvector centrality of a node approximately determines its risk to become infected.

title: Deciphering the tectonics of the Greater Caucasus from post-collisional volcanism
Creators: name: Bewick, Samuel
Publisher: name: The Open University
Year: 2017

description: The southern margin of the Eurasian plate is a well-studied region of continental collision. The Caucasus mountains lie at the centre of the Alpine-Himalayan orogenic belt, and differs from their better studied neighbours by the presence of intense, largely mantle derived post-collisional magmatism. Volcanism began 5-15 Ma after the initial collision occurred, and after the crust had already thickened to 45-60 km. This thesis presents bulk rock and mineral element and isotope geochemistry to assess the role of asthenosphere, lithosphere and crust in generating contemporaneous volcanism across the region. Broad similarities are seen between volcanism in the Greater and Lesser Caucasus, dominated by calc-alkaline basalt-dacite (48-72 wt% SiO2) compositions. High Mg# cores (>85) of olivines suggest significant fractionation has occurred. Trace element patterns show a distinctive supra-subduction setting, suggesting the fluid-enriched source remained in place, and hydrated >10 Ma following collision. Isotope ratios require an asthenospheric component in the early Lesser Caucasus melts, whilst sediment-enrichment of the source is observed across the region. Little interaction with the thickened crust is observed. For the Lesser Caucasus, a model of Palaeo-Tethyan slab breakoff is proposed, resulting in asthenospheric upwelling and melting of an enriched lithosphere. Small-scale convection continues to produce drips, leading to episodic pulses of magmatism. Subduction of back-arc crust with slab breakoff is proposed beneath the Greater Caucasus, allowing melting of enriched lithosphere, with distinguishable fluid, and slab-melt components. Although contemporaneous, and volcanism in the Lesser and Greater Caucasus being geochemically similar in many respects, a shared source is ruled out because of tectonic constraints. Strike-slip faulting, the result of a tectonic regime shift at 5 Ma, determined the location of volcanoes. Although the style of post-collisional magmatism may not be characteristic of all continental collision zones, where present it has a high preservation potential. It may therefore play a significant role in the formation, and composition of continental crust that is largely unrecognised in models of continental crust evolution.

description: The sensitivity of the SKA enables a number of tests of theories of gravity. A Galactic Census of pulsars will discover most of the active pulsars in the Galaxy beamed toward us. In this census will almost certainly be pulsar-black hole binaries as well as pulsars orbiting the super-massive black hole in the Galactic centre. These systems are unique in their capability to probe the ultra-strong field limit of relativistic gravity. These measurements can be used to test the Cosmic Censorship Conjecture and the No-Hair theorem. The large number of millisecond pulsars discovered with the SKA will also provide a dense array of precision clocks on the sky. These clocks will act as the multiple arms of a huge gravitational wave detector, which can be used to detect and measure the stochastic cosmological gravitational wave background that is expected from a number of sources.

description: The evaluation of the sub-saturation nuclear equation of state at finite temperature requires a proper state counting of the internal partition sum of nuclei which are immersed in the background of their continuum states. This classical statistical problem is addressed within the self-consistent mean-field approximation, which naturally accounts for isospin and effective mass effects in the nuclear density of states. The nuclear free energy is decomposed into bulk and surface terms, allowing a simple analytical prescription for the subtraction of gas states from the nuclear partition sum, that avoids double counting of unbound single particle states. We show that this correction leads to a sizeable effect in the composition of matter at high temperature and low proton fractions, such as it is formed in supernova collapse, early proto-neutron star evolution, as well as laboratory experiments. Specifically, the energy stored in the internal nuclear degrees of freedom is reduced, as well as the mass fraction of heavy clusters in the statistical equilibrium. The gas subtraction prescription is compared to different phenomenological methods proposed in the literature, based on a high energy truncation of the partition sum. We show that none of these methods satisfactorily reproduces the gas subtracted level density, if the temperature overcomes ~4 MeV.

description: An elegant and convenient rigorous approach for solving circular open-ended dielectric-loaded waveguide diffraction problems is presented. It uses the solution of corresponding Wiener-Hopf-Fock equation and leads to an infinite linear system for reflection coefficients (S-parameters) of the waveguide, the latter can be efficiently solved numerically using the reducing technique. As a specific example directly applicable to beam-driven radiation sources based on dielectric-lined capillaries, diffraction of a slow TM symmetrical mode at the open end of a circular waveguide with uniform dielectric filling is considered. A series of such modes forms the wakefield (Cherenkov radiation field) generated by a charged particle bunch during its passage along the waveguide axis. Calculated S-parameters were compared with those obtained from COMSOL simulation and an excellent agreement is shown. This method is expected to be very convenient for analytical investigation of various electromagnetic interactions of Terahertz (THz) waves (both free and guided) and charged particle bunches with slow-wave structures prospective in context of modern beam-driven THz emitters, THz accererators and THz-based bunch manipulation and bunch diagnostic systems.

description: The structural, morphological, the measurement of the energy of characteristic X-ray emissionsof excited specimens and microwave absorbing properties were examined by using XRD, SEM, EDSand testing source network Analyser, respectively. The shielding results indicated that Fe3O4 were coatedwith polymer chains of POT and interfaces between them. The results were created at the 0.19mm ofthickness and acquired a minimum reflection (RL) of -16dB at 1.99 GHz with the absorption loss of -2.39 dB. Moreover, the maximum achieved value for the maximum and minimum absorption loss areperceived to be 6.1dB and 3.0dB with the collective effect of shielding 9 dB at 17GHz. It is determinedthat shielding response of composite, enhanced with the frequency increase and vice versa. Theseconsequences demonstrate the material retain modest shielding performance and can be authorized asEMI shielding material owing to its favourable microwave frequency at merely 0.199 mm of thickness.

description: Changes of the electron work-function of a superconductor proportional to the square of the current density $Δϕ= -βj^2$ are known as Bernoulli effect in superconductors or current induced Contact Potential Difference (CPD). The temperature dependent constant $β(T;m^{\star})$ is parametrized by the effective mass of Cooper pairs $m^{\star}$. In such a way the study of the Bernoulli effect leads to creation of Cooper pair mass-spectroscopy. In this paper a short review on the Bernoulli effect in superconductors is given and a proposed experimental set-up for its measurement is described in detail. The experiment requires standard electronic equipment and can be implemented in every laboratory related to physics of superconductivity. This experimental set-up for observation of current induced CPD requires nano-technological hybrid superconductor structures with atomically clean interfaces and measurement of nano-volt signals with capacitive coupling to the sample.

description: Precise calculations of core properties in heavy-atom systems which are described by the operators heavily concentrated in atomic cores, like to hyperfine structure and P,T-parity nonconservation effects, usually require accounting for relativistic effects. Unfortunately, completely relativistic treatment of molecules containing heavy elements is very consuming already at the stages of calculation and transformation of two-electron integrals with a basis set of four-component spinors. In turn, the relativistic effective core potential (RECP) calculations of valence (spectroscopic, chemical etc.) properties of molecules are very popular because the RECP method allows one to treat quite satisfactory the correlation and relativistic effects for the valence electrons of a molecule and to reduce significantly the computational efforts. The valence molecular spinors are usually smoothed in atomic cores and, as a result, direct calculation of electronic densities near heavy nuclei is impossible. In the paper, the methods of nonvariational and variational one-center restoration of correct shapes of four-component spinors in atomic cores after a two-component RECP calculation of a molecule are discussed. Their efficiency is illustrated in correlation calculations of hyperfine structure and parity nonconservation effects in heavy-atom molecules YbF, BaF, TlF, and PbO.

We are performing simulations with three degenerate quarks with masses less than or equal to the strange quark mass m_s and with degenerate up and down quarks with masses m_{u,d} less than the strange quark mass. For the quark masses studied to date, we find a crossover that strengthens as m_{u,d} decreases, rather than a bona fide phase transition. We present new results for the crossover temperature extrapolated to the physical value of m_{u,d}, and for quark number susceptibilities.

description: We study string interaction rates in the Brandenberger-Vafa scenario, the very early universe cosmology of a gas of strings. This cosmology starts with the assumption that all spatial dimensions are compact and initially have string scale radii; some dimensions grow due to some thermal or quantum fluctuation which acts as an initial expansion velocity. Based on simple arguments from the low energy equations of motion and string thermodynamics, we demonstrate that the interaction rates of strings are negligible, so the common assumption of thermal equilibrium cannot apply. We also present a new analysis of the cosmological evolution of strings on compact manifolds of large radius. Then we discuss modifications that should be considered to the usual Brandenberger-Vafa scenario. To confirm our simple arguments, we give a numerical calculation of the annihilation rate of winding strings. In calculating the rate, we also show that the quantum mechanics of strings in small spaces is important.

description: We explore the influence of non-geodesic pressure forces that are present in an accretion disk on the frequencies of its axisymmetric and non-axisymmetric epicyclic oscillation modes. {We discuss its implications for models of high-frequency quasi-periodic oscillations (QPOs) that have been observed in the X-ray flux of accreting black holes (BHs) in the three Galactic microquasars, GRS 1915+105, GRO J1655$-$40 and XTE J1550$-$564. We focus on previously considered QPO models that deal with low azimuthal number epicyclic modes, $\lvert m \rvert \leq 2$, and outline the consequences for the estimations of BH spin, $a\in[0,1]$.} For four out of six examined models, we find only small, rather insignificant changes compared to the geodesic case. For the other two models, on the other hand, there is a fair increase of the estimated upper limit on the spin. Regarding the QPO model's falsifiability, we find that one particular model from the examined set is incompatible with the data. If the microquasar's spectral spin estimates that point to $a>0.65$ were fully confirmed, two more QPO models would be ruled out. Moreover, if two very different values of the spin, such as $a\approx 0.65$ in GRO J1655$-$40 vs. $a\approx 1$ in GRS 1915+105, were confirmed, all the models except one would remain unsupported by our results. Finally, we discuss the implications for a model recently proposed in the context of neutron star (NS) QPOs as a disk-oscillation-based modification of the relativistic precession model. This model provides overall better fits of the NS data and predicts more realistic values of the NS mass compared to the relativistic precession model. We conclude that it also implies a significantly higher upper limit on the microquasar's BH spin ($a\sim 0.75$ vs. $a\sim 0.55$).

Das erste Jahr im Projekt „Policy Alignment of Open Access Monographs in the European Research Area” (PALOMERA)
Creators: name: Tummes, Jan-Philip
Publisher: name: Kolloquium Wissensinfrastruktur
Year: 2023

description: Bücher spielen eine wichtige Rolle in der Wissenschaftskommunikation - besonders in den Sozial- und Geisteswissenschaften. Im Hinblick auf die Open-Access-Transformation haben sich die Bemühungen von (politischen) Entscheidungsträgern und Forschungsförderern bisher allerdings weniger auf wissenschaftliche Bücher als auf Artikel in Fachzeitschriften fokussiert. Das seit Januar 2023 laufende und von der Europäischen Union geförderte Projekt PALOMERA adressiert diese Asymmetrie im europäischen Forschungsraum und erarbeitet Handlungsempfehlungen für die Entwicklung von Open-Access-Policies für Bücher.


Der Vortrag stellt das Projekt PALOMERA vor, fasst die Arbeiten des ersten Jahres zusammen und präsentiert Ergebnisse aus einer PALOMERA-Umfrage zum Thema Open-Access-Bücher und -Policies.

Radiation of a Charge in Axicon-Based Dielectric Concentrator for Cherenkov Radiation
Creators: name: Galyamin, Sergey N.

Publisher: name: arXiv
Year: 2020
Subjects: subject: Accelerator Physics (physics.acc-ph)

description: We propose a new type of axisymmetric dielectric target which effectively concentrates Cherenkov radiation (CR) generated in the bulk of the material into a small vicinity of focus point. It can be called the "axicon-based concentrator for CR". A theoretical investigation of radiation field produced by a charge moving through the discussed radiator is performed for the general case where a charge trajectory is shifted with respect to the structure axis. The idea of dielectric target with specific profile of the outer surface was presented and developed in our preceeding papers. However, contrary to the previous configuration of such a target (which was investigated for both centered and shifted charge trajectory), the current version allows efficient concentration of CR energy from relativistic particles, making this device extremely prospective for various applications.

Creative writing practice and pedagogy : a Jungian approach
Creators: name: Sonik, Madeline
Publisher: name: University of British Columbia
Year: 2010

description: In conventional Creative Writing post-secondary classes, the focus of student training is technique, to the neglect of the unconscious in the learning process. Some educators, in fact, suggest that the role and workings of the unconscious are dangerous areas for Creative Writing educators to explore. This thesis, drawing on the work of Carl Jung, as well as of Jungians and post-Jungians, advocates that the unconscious, in fact, needs to be valued and worked with purposefully in the Creative Writing classroom. The notion of archetype, with particular reference to the "archetypal feminine," is explored in this context. At the outset it is argued that the primary elements of what has collectively been considered "great literature" consist of far more than their mere technical components. The transformational qualities of great literature arise through a flux of the living experience of universal human themes. These "archetypes," as Jung called them, cannot be reduced to merely technical tools intended to assist the writer’s ego: they are autonomous energies that demand the ego’s engagement if they are to be integrated and expressed. Jung used the term "individuation" to signify the evolution of ego consciousness in an individual. This thesis introduces the concept of a "literary individuation," in which student writers can find personal growth and maturation by engaging with the unconscious in the writing processes. By defining and then applying many of Jung’s conceptualizations to Creative Writing practice and pedagogy, the generative importance of the ignored unconscious and the "archetypal feminine" begins to emerge. Student writers can use Jungian constructs to better understand their characters, their writing, their own personalities, and their lives, while educators might consider making constructive curricular modifications that acknowledge and reinstate the importance of the unconscious.
title: Investigation Into The Molecular Mechanisms Underlying Idiopathic Intracranial Hypertension
Creators: name: Alimajstorovic, Zerin
Publisher: name: The Open University
Year: 2017

description: Idiopathic intracranial hypertension (IIH) is a neurological disorder characterised by raised cerebrospinal fluid (CSF) pressure in the absence of any intracranial pathology. IIH mainly affects obese women between the ages of 15 and 45. Two possible mechanisms that could explain the increased CSF pressure in IIH are excessive CSF production by the choroid plexus epithelium or impaired CSF drainage back into the venous blood but the molecular mechanisms controlling these in IIH remain to be determined.

 In vivo ventriculo-cisternal perfusion and variable rate infusion techniques assessed changes in rates of CSF secretion/resistance to CSF drainage in male and female Wistar rats fed either a normal control or high-fat (HF) diet, following treatment with inflammatory mediators already found to be elevated in the CSF of IIH patients: chemokine (C-C motif) ligand 2 (CCL2), interleukin (IL)-17 (IL-17), IL-6, IL-1β, tumour necrosis factor-α (TNF-α), as well as adipocyte-derived hormone leptin and the glucocorticoid hydrocortisone (HC).

 Female Wistar rats raised on a HF diet were shown to have the highest CSF secretion and lowest CSF drainage rates under untreated conditions. Increased CSF secretion was observed in rats of all genders and diets following TNF-α or HC treatment, however the greatest increase by TNF-α and HC over basal levels was observed in female rats raised on a HF diet. In addition, female rats on a HF diet, treated with CCL2 or IL-17, displayed an increase in resistance to CSF drainage when compared to untreated controls (indicating lower levels of CSF drainage).

 Therapies targeting HC, TNF-α, CCL2 and/or IL-17, whether separately or in combination, may be beneficial to modulate rates of CSF secretion and/or resistance to CSF drainage pathways, both factors likely contributing to the raised intracranial pressure observed in obese female IIH patients.

description: We investigate the long-time evolution of magnetic fields generated by the two-stream instability at ultra- and sub-relativistic astrophysical collisionless shocks. Based on 3D PIC simulation results, we introduce a 2D toy model of interacting current filaments. Within the framework of this model, we demonstrate that the field correlation scale in the region far downstream the shock grows nearly as the light crossing time, lambda(t) ~ ct, thus making the diffusive field dissipation inefficient. The obtained theoretical scaling is tested using numerical PIC simulations. This result extends our understanding of the structure of collisionless shocks in gamma-ray bursts and other astrophysical objects.

description: The lithium abundance in 62 halo dwarfs is determined from accurate equivalent widths reported in the literature and an improved infrared flux method (IRFM) temperature scale. The Li abundance of 41 plateau stars (those with Teff > 6000 K) is found to be independent of temperature and metallicity, with a star-to-star scatter of only 0.06 dex over a broad range of temperatures (6000 K < Teff < 6800 K) and metallicities (-3.4 < [Fe/H] < -1), thus imposing stringent constraints on depletion by mixing and production by Galactic chemical evolution. We find a mean Li plateau abundance of A(Li) = 2.37 dex (7Li/H = 2.34 X 10^{-10}), which, considering errors of the order of 0.1 dex in the absolute abundance scale, is just in borderline agreement with the constraints imposed by the theory of primordial nucleosynthesis and WMAP data (2.51 < A(Li)[WMAP] < 2.66 dex).

description: We investigate the effect of small spatiotemporal modulations in subwavelength-dimensioned phononic crystals with large band gaps, on the frequency spectrum for elastic waves polarized in the plane of periodicity. When the radius of cylinders periodically placed inside a matrix of highly-contrasting elastic properties is time-varying, we find that due to the appearance of frequency harmonics throughout the spectrum, the notion of a band gap is destroyed in general, although with the appropriate tuning of parameters, in particular the modulation frequency, it is possible that some band-gap region is retained, making such systems possible candidates for tunable bandpass filters or phononic isolators, accordingly, and for sensor applications.

title: A Novel Inpainting Framework for Virtual View Synthesis
Creators: name: Reel, Smarti
Publisher: name: The Open University
Year: 2017

description: Multi-view imaging has stimulated significant research to enhance the user experience of free viewpoint video, allowing interactive navigation between views and the freedom to select a desired view to watch. This usually involves transmitting both textural and depth information captured from different viewpoints to the receiver, to enable the synthesis of an arbitrary view. In rendering these virtual views, perceptual holes can appear due to certain regions, hidden in the original view by a closer object, becoming visible in the virtual view. To provide a high quality experience these holes must be filled in a visually plausible way, in a process known as inpainting. This is challenging because the missing information is generally unknown and the hole-regions can be large. Recently depth-based inpainting techniques have been proposed to address this challenge and while these generally perform better than non-depth assisted methods, they are not very robust and can produce perceptual artefacts. This thesis presents a new inpainting framework that innovatively exploits depth and textural self-similarity characteristics to construct subjectively enhanced virtual viewpoints. The framework makes three significant contributions to the field: i) the exploitation of view information to jointly inpaint textural and depth hole regions; ii) the introduction of the novel concept of self-similarity characterisation which is combined with relevant depth information; and iii) an advanced self-similarity characterising scheme that automatically determines key spatial transform parameters for effective and flexible inpainting. The presented inpainting framework has been critically analysed and shown to provide superior performance both perceptually and numerically compared to existing techniques, especially in terms of lower visual artefacts. It provides a flexible robust framework to develop new inpainting strategies for the next generation of interactive multi-view technologies.
Vowels and Prosody Contribution in Neural Network Based Voice Conversion Algorithm with Noisy Training Data

description: This research presents a neural network based voice conversion (VC) model. While it is a known fact that voiced sounds and prosody are the most important component of the voice conversion framework, what is not known is their objective contributions particularly in a noisy and uncontrolled environment. This model uses a 2-layer feedforward neural network to map the Linear prediction analysis coefficients of a source speaker to the acoustic vector space of the target speaker with a view to objectively determine the contributions of the voiced, unvoiced and supra-segmental components of sounds to the voice conversion model. Results showed that vowels 'a', 'i', 'o' have the most significant contribution in the conversion success. The voiceless sounds were also found to be most affected by the noisy training data. An average noise level of 40 dB above the noise floor were found to degrade the voice conversion success by 55.14 percent relative to the voiced sounds. The result also shows that for cross-gender voice conversion, prosody conversion is more significant in scenarios where a female is the target speaker.
