description: Spectroscopic ellipsometry is used to determine the dielectric function of the superconducting LaFeAsO$_{0.9}$F$_{0.1}$ ($T_c$ = 27 K) and undoped LaFeAsO polycrystalline samples in the wide range 0.01-6.5 eV at temperatures 10 $\leq T \leq$ 350 K. The free charge carrier response in both samples is heavily damped with the effective carrier density as low as 0.040$\pm$0.005 electrons per unit cell. The spectral weight transfer in the undoped LaFeAsO associated with opening of the pseudogap at about 0.65 eV is restricted at energies below 2 eV. The spectra of superconducting LaFeAsO$_{0.9}$F$_{0.1}$ reveal a significant transfer of the spectral weight to a broad optical band above 4 eV with increasing temperature. Our data may imply that the electronic states near the Fermi surface are strongly renormalized due to electron-phonon and/or electron-electron interactions.

description: We show that a coupling between chameleon-like scalar fields and photons induces linear and circular polarization in the light from astrophysical sources. In this context chameleon-like scalar fields includes those of the Olive-Pospelov (OP) model describing a varying fine structure constant. We determine the form of this polarization numerically and give analytic expressions in two useful limits. By comparing the predicted signal with current observations we are able to improve the constraints on the chameleon-photon coupling and the coupling in the OP model by over two orders of magnitude. It is argued that, if observed, the distinctive form of the chameleon induced circular polarization would represent a smoking gun for the presence of a chameleon. We also report a tentative statistical detection of a chameleon-like scalar field from observations of starlight polarization in our galaxy.

Hamiltonian Approach to 1+1 dimensional Yang-Mills theory in Coulomb gauge

description: We study the Hamiltonian approach to 1+1 dimensional Yang-Mills theory in Coulomb gauge, considering both the pure Coulomb gauge and the gauge where in addition the remaining constant gauge field is restricted to the Cartan algebra. We evaluate the corresponding Faddeev-Popov determinants, resolve Gauss' law and derive the Hamiltonians, which differ in both gauges due to additional zero modes of the Faddeev-Popov kernel in the pure Coulomb gauge. By Gauss' law the zero modes of the Faddeev-Popov kernel constrain the physical wave functionals to zero colour charge states. We solve the Schroedinger equation in the pure Coulomb gauge and determine the vacuum wave functional. The gluon and ghost propagators and the static colour Coulomb potential are calculated in the first Gribov region as well as in the fundamental modular region, and Gribov copy effects are studied. We explicitly demonstrate that the Dyson-Schwinger equations do not specify the Gribov region while the propagators and vertices do depend on the Gribov region chosen. In this sense, the Dyson-Schwinger equations alone do not provide the full non-abelian quantum gauge theory, but subsidiary conditions must be required. Implications of Gribov copy effects for lattice calculations of the infrared behaviour of gauge-fixed propagators are discussed. We compute the ghost-gluon vertex and provide a sensible truncation of Dyson-Schwinger equations. Approximations of the variational approach to the 3+1 dimensional theory are checked by comparison to the 1+1 dimensional case.

description: We present new spectroscopic and photometric observations of the HAT-P-1 planetary system. Spectra obtained during three transits exhibit the Rossiter-McLaughlin effect, allowing us to measure the angle between the sky projections of the stellar spin axis and orbit normal, λ= 3.7 +/- 2.1 degrees. The small value of λfor this and other systems suggests that the dominant planet migration mechanism preserves spin-orbit alignment. Using two new transit light curves, we refine the transit ephemeris and reduce the uncertainty in the orbital period by an order of magnitude. We find a upper limit on the orbital eccentricity of 0.067, with 99% confidence, by combining our new radial-velocity measurements with those obtained previously.

Physical development contributions to biomechanical injury risk in female gymnasts

Publisher: name: Cardiff Metropolitan University

Subjects: Sports science and exercise not elsewhere classified

description: Ongoing chronic back pain and chronic spinal injury prevalence in the gymnastics population is a major concern for the health and wellbeing of female gymnasts. To inform biomechanical screening approaches, the aim of the research is to develop understanding of the contribution of physical development to biomechanical indicators of chronic spinal injury risk in female artistic gymnasts. Chronological ageing, maturation and growth of competitive female artistic gymnasts between the ages of nine and 15 years were evaluated at three time points across a 12 month period. CODA motion analysis and Kistler force plate data informed the quantification of biomechanical risk indicators. Posture, general stability, centre of pressure range and lumbo-pelvic stability were determined through the performance of handstand and forward walkover skills and informed the respective risk indicators. Calculated through an image-based approach, anthropometric growth was established to have the greatest influence on biomechanical risk indicators of the physical development mechanisms. Within the gymnastics cohort, two forms of proportional growth were evidenced. Longitudinal empirical data revealed gymnasts with increased bicristal breadth growth in relation to biacromial breadth to have significantly greater biomechanical risk for posture and lumbo-pelvic stability in the handstand (p<0.05). Gymnasts who had increased growth rates of biacromial breadth in relation to bicristal breadth had significantly greater biomechanical risk for general stability in the handstand and forward walkover skills (p<0.05). Novel empirical quantification for the large influences of physical development mechanisms on biomechanical risk (maximum r2 = 0.82) underpinned the importance of proportional growth consideration in injury screening practice. Evaluation of the transverse torso moment of inertia at a discrete time point provided preliminary support for cross-sectional use of the inertial measure to forecast longitudinal growth trends. Identification of prominent biomechanical risk indicators for individual gymnasts using discrete data may provide direction of injury prevention focus for practitioners.

description: The cyclotron frequency ratio of $^{187}\mathrm{Os}^{29+}$ to $^{187}\mathrm{Re}^{29+}$ ions was measured with the Penning-trap mass spectrometer PENTATRAP. The achieved result of $R=1.000\:000\:013\:882(5)$ is to date the most precise such measurement performed on ions. Furthermore, the total binding-energy difference of the 29 missing electrons in Re and Os was calculated by relativistic multiconfiguration methods, yielding the value of $ΔE = 53.5(10)$ eV. Finally, using the achieved results, the mass difference between neutral $^{187}$Re and $^{187}$Os, i.e., the $Q$ value of the $β^-$ decay of $^{187}$Re, is determined to be 2470.9(13) eV.

Distortion of Wigner molecules : pair function approach

description: We considered a two dimensional three electron quantum dot in a magnetic field in the Wigner limit. A unitary coordinate transformation decouples the Hamiltonian (with Coulomb interaction between the electrons included) into a sum of three independent pair Hamiltonians. The eigen-solutions of the pair Hamiltonian provide a spectrum of pair states. Each pair state defines the distance of the two electrons involved in this state. In the ground state for given pair angular momentum $m$, this distance increases with increasing $|m|$. The pair states have to be occupied under consideration of the Pauli exclusion principle, which differs from that for one-electron states and depends on the total spin $S$ and the total orbital angular momentum $M_L=\sum m_i$ (sum over all pair angular momenta). We have shown that the three electrons in the ground state of the Wigner molecule form an equilateral triangle (as might be expected) only, if the state is a quartet ($S=3/2$) and the orbital angular momentum is a magic quantum number ($M_L=3 m ; m=$ integer). Otherwise the triangle in the ground state is isosceles. For $M_L=3 m+1$ one of the sides is longer and for $M_L=3 m-1$ one of the sides is shorter than the other two.

description: We show analytically using a macrospin approximation that easy-plane spin Hall nano-oscillators excited by a spin-current polarized perpendicularly to the easy-plane have phase dynamics analogous to that of Josephson junctions. Similarly to Josephson junctions, they can reproduce the spiking behavior of biological neurons that is appropriate for neuromorphic computing. We perform micromagnetic simulations of such oscillators realized in the nano-constriction geometry and show that the easy-plane spiking dynamics is preserved in an experimentally feasible architecture. Finally we simulate two elementary neural network blocks that implement operations essential for neuromorphic computing. First, we show that output spikes energies from two neurons can be summed and injected into a following layer neuron and second, we demonstrate that outputs can be multiplied by synaptic weights implemented by locally modifying the anisotropy.

description: Precision data from cosmology suggest neutrinos stream freely and hence interact very weakly around the epoch of recombination. We study this issue in a simple framework where neutrinos recouple instantaneously and stop streaming freely at a redshift z_i. The latest cosmological data imply z_i < 1500, the exact constraint depending somewhat on the assumed prior on z_i. This bound translates into a limit on the coupling strength between neutrinos and majoron-like particles phi, implying tau > 1 x 10^10 s (m_2/50 meV)^3 for the decay nu_2 -> nu_1+phi.

Lifelogging with SAESNEG: a system for the automated extraction of social network event groups
Creators: name: Blamey, Benjamin
Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Data management and data science not elsewhere classified

description: This thesis presents SAESNEG, a System for the Automated Extraction of Social Network Event Groups; a pipeline for the aggregation of the personal social media footprint, and its partitioning into events, the event clustering problem. SAESNEG facilitates a reminiscence-friendly user experience, where the user is able to navigate their social media footprint. A range of socio-technical issues are explored: the challenges to reminiscence, lifelogging, ownership, and digital death. Whilst previous systems have focused on the organisation of a single type of data, such as photos or Tweets respectively; SAESNEG handles a variety of types of social network documents found in a typical footprint (e.g. photos, Tweets, check-ins), with a variety of image, text and other metadata di erently heterogeneous data; adapted to sparse, private events typical of the personal social media footprint. Phase A extracts information, focusing on natural language processing; new techniques are developed; including a novel distributed approach to handling temporal expressions, and a parser for social events (such as birthdays). Information is also extracted from image and metadata, the resultant annotations feeding the subsequent event clustering. Phase B performs event clustering through the application of a number of pairwise similarity strategies a mixture of new and existing algorithms. Clustering itself is achieved by combining machine-learning with correlation clustering. The main contributions of this thesis are the identi cation of the technical research task (and the associated social need), the development of novel algorithms and approaches, and the integration of these with existing algorithms to form the pipeline. Results demonstrate SAESNEG's capability to perform event clustering on a differently heterogeneous dataset, enabling users to achieve lifelogging in the context of their existing social media networks.

Early Initiation of Inner Solar System Formation at Dead-Zone Inner Edge

description: The inner solar system possesses a unique orbital structure in which there are no planets inside the Mercury orbit and the mass is concentrated around the Venus and Earth orbits. The origins of these features still remain unclear. We propose a novel concept that the building blocks of the inner solar system formed at the dead-zone inner edge in the early phase of the protosolar disk evolution, where the disk is effectively heated by the disk accretion. First, we compute the dust evolution in a gas disk with a dead zone and obtain the spatial distribution of rocky planetesimals. The disk is allowed to evolve both by a viscous diffusion and magnetically-driven winds. We find that the rocky planetesimals are formed in concentrations around $\sim$ 1 au with a total mass comparable to the mass of the current inner solar system in the early phase of the disk evolution within $\lesssim0.1$ Myr. Based on the planetesimal distribution and the gas disk structure, we subsequently perform \textit{N}-body simulations of protoplanets to investigate the dynamical configuration of the planetary system. We find that the protoplanets can grow into planets without significant orbital migration because of the rapid clearing of the inner disk by the magnetically-driven disk winds. Our model can explain the origins of the orbital structure of the inner solar system. Several other features such as the rocky composition can also be explained by the early formation of rocky planetesimals.

description: We provide a brief commentary on recent work by Hammer and Son on the scaling behavior of nuclear reactions involving the emission of several loosely bound neutrons. In this work they discover a regime, termed unnuclear physics, in which these reactions are governed by an approximate conformal symmetry of the nuclear force. Remarkably, the scaling exponents that govern nuclear reactions can be related to the energies of ultracold atomic drops confined in harmonic potentials. We also comment on the importance and the limitations of this approximate symmetry in the physics of neutron stars.

Phase Transitions, theta Behavior and Instantons in QCD and its Holographic Model

description: In the holographic model of QCD, theta dependence sharply changes at the point of confinement deconfinement phase transition. In large N QCD such a change in theta behavior can be related to the breakdown of the instanton expansion at some critical temperature T_c. Associating this temperature with confinement-deconfinement phase transition leads to the description of the latter in terms of dissociation of instantons into the fractionally charged instanton quarks. To elucidate this picture, we introduce the nonvanishing chiral condensate in the deconfining phase and assume a specific lagrangian for the eta' field in the confining phase. In the resulting picture the high temperature phase of the theory consists of the dilute gas of instantons, while the low temperature phase is described in terms of freely moving fractional instanton quarks.

L’amour et la violence dans l’oeuvre de Jacques Roumain
Creators: name: Lorenzon Fumagalli, Gabriella
Publisher: name: University of British Columbia
Year: 2010

description: Le but de ce travail est l'étude approfondie de quelques oeuvres de Jacques Roumain (malheureusement, je n'ai pas pu avoir à ma disposition Les Fantoches et Le Champ du Potier) à la lumière de deux éléments qui semblent obséder les romans, les essais et les poèmes de l'écrivain haïtien: l'Amour et la Violence. Après une présentation de Jacques Roumain et du climat socio-politique dans lequel il a vécu, et qui constitue le décor de tous ses écrits (Chapitre I), je procède à un examen approfondi des Nouvelles, La Proie et l'Ombre (Chapitre II), du récit-paysan, La Montagne Ensorcelée (Chapitre III), et du roman le plus fameux: Gouverneurs de la Rosée (Chapitre IV). Au fur et a mesure que mon étude avance, je découvre que, sous des formes littéraires différentes, se cache la même, obsédante intéraction, le même "jeu rituel" entre l'Amour et la Violence. Ces deux éléments passionnels saturent l'atmosphère jusqu'au point culminant où se déclenchera le mécanisme du Bouc Emissaire. Son Sacrifice dissout une Violence apaisée. Cette sorte de schéma littéraire est évident même dans les aspects politique, religieux et poétique de l'oeuvre de Jacques Roumain (Chapitres V, VI, VII); c'est ce uqe j'essaye de démontrer dans les derniers chapitres. Le chapitre VIII est la synthèse, le résultat de l'analyse faite au cours de ma thèse. J'y étudie, en oiùtre, l'évolution de la pensée de l'auteur, qui se reflète dans son effort littéraire et le modifie à trois différents niveaux: 1- celui de l'idéologie socio-politique, 2- celui du langage, 3- celui de la conception du Bouc Emissaire.

Interconversion-controlled liquid-liquid phase separation in a molecular chiral model

description: Liquid-liquid phase separation of liquids exhibiting interconversion between alternative states has been proposed as an underlying mechanism for fluid polyamorphism, and may be of relevance to protein function and intracellular organization. However, molecular-level insight into the interplay between competing forces that can drive or restrict phase separation in interconverting fluids remains elusive. Here, we utilize an off-lattice model of enantiomers with tunable chiral interconversion and interaction properties to elucidate the physics underlying the stabilization and tunability of phase separation in fluids with interconverting states. We show that introducing an imbalance in the intermolecular forces between two enantiomers results in nonequilibrium, arrested phase separation into microdomains. We also find that in the equilibrium case, when all interaction forces are conservative, the growth of the phase domain is restricted only by system size. In this case, we observe phase amplification, in which one of the two alternative phases grows at the expense of the other. These findings provide novel insights on how the interplay between dynamics and thermodynamics defines the equilibrium and steady-state morphologies of phase transitions in fluids with interconverting molecular or supramolecular states.

Privatisation of the Nigerian Railway Corporation: An evaluation of critical choices

Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Rail transportation and freight services

description: An efficient transport system is a catalyst for economic development the world over, therefore rail transport plays a significant role in the socio-economic activity of any nation. The Nigerian Railway Corporation (NRC) is currently confronted with numerous problems ranging from operational, capacity building, management and customer patronage (Adesanya, 2010; Osborne, 1993). Successive governments at various times have all played a part in an effort to make the service efficient, productive, operate maximally and at best profitable but to no avail. Several billions of dollars have been expended on rail transport at different times to rejuvenate the service and make it operationally viable, but there is little evidence to justify all sums of money invested on the service let alone the impact of government intervention felt in resuscitating the rail transport (Ademiluyi and Dina, 2011; Adeyemo and Salami, 2008; Jerome, 2008). Research methodology includes a review of relevant theories such as agency theory, property right theory, resource-based theory, and contingency theory, a comparative analysis of the UK privatisation of the national rail system as well as rail privatisation in Africa. Survey questionnaire was used to solicit information from informed consent respondents on four virtual survey samples identified and considered for the study. The study results and statistical hypothesis tests of counterfactual opinion carried out on the research purpose was inconclusive. The survey indicated that 3 out of 4 samples tested concluded that there was no evidence to suggest a relationship between a choice of privatisation method and NRC performance. However, results of other sample indicated that there is strong relationship between privatisation of NRC and its performance indicators. Although there is no relationship between the choice of privatisation method and NRC performance, there is strong evidence to suggest that there is a relationship between privatisation and improvement of NRC performance indicators.

Electroweak Breaking on a Soft Wall

Year: 2008
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We extend the 5D gauge-higgs scenario to the soft-wall framework where the IR brane is replaced by a smoothly decaying warp factor. The electroweak symmetry of the Standard Model is embedded in a larger symmetry group whose gauge bosons propagate in the bulk of a warped fifth dimension. This gauge symmetry is partly broken by UV boundary conditions and by a condensate of a bulk scalar field. The Higgs boson lives partly in the 5th component of the gauge field, and partly in the the bulk scalar. The Higgs potential is not UV sensitive if the condensate vanishes fast enough in the UV region. The soft-wall realization opens new possibilities for the spectrum and the couplings of the Kaluza-Klein resonances. We study two particular soft-wall backgrounds: one with resonances whose masses follow the linear Regge trajectory, and another with a continuum above a mass gap. We find that constraints on the Kaluza-Klein scale from electroweak precision tests are less severe than in analogous models with the IR brane. For the linear spectrum the typical constraint on the lightest resonance mass is 2 TeV, while the continuum is allowed to start below 1 TeV.
