description: Fragmentation methods applied to multireference wave functions constitute a road towards the application of highly accurate ab initio wave function calculations to large molecules and solids. However, it is important for reproducibility and transferability that a fragmentation scheme be well-defined with minimal dependence on initial orbital guesses or user-designed ad hoc fragmentation schemes. One way to improve this sort of robustness is to ensure the energy obeys a variational principle; i.e., that the active orbitals and active space wave functions minimize the electronic energy in a certain ansatz for the molecular wave function. We extended the theory of the localized active space self-consistent field, LASSCF, method (JCTC 2019, 15, 972) to fully minimize the energy with respect to all orbital rotations, rendering it truly variational. The new method, called vLASSCF, substantially improves the robustness and reproducibility of the LAS wave function compared to LASSCF. We analyze the storage and operation cost scaling of vLASSCF compared to orbital optimization using a standard CASSCF approach and we show results of vLASSCF calculations on some simple test systems. We show that vLASSCF is energetically equivalent to CASSCF in the limit of one active subspace, and that vLASSCF significantly improves upon the reliability of LASSCF energy differences, allowing for more meaningful and subtle analysis of potential energy curves of dissociating molecules. We also show that all forms of LASSCF have a lower operation cost scaling than the orbital-optimization part of CASSCF.

description: The study aims to understand Twitter users' discourse and psychological reactions to COVID-19. We use machine learning techniques to analyze about 1.9 million Tweets (written in English) related to coronavirus collected from January 23 to March 7, 2020. A total of salient 11 topics are identified and then categorized into ten themes, including "updates about confirmed cases," "COVID-19 related death," "cases outside China (worldwide)," "COVID-19 outbreak in South Korea," "early signs of the outbreak in New York," "Diamond Princess cruise," "economic impact," "Preventive measures," "authorities," and "supply chain." Results do not reveal treatments and symptoms related messages as prevalent topics on Twitter. Sentiment analysis shows that fear for the unknown nature of the coronavirus is dominant in all topics. Implications and limitations of the study are also discussed.
title: The role of evangelicalism in the formation of nineteenth-century Ulster protestant cultural identity (1859-1885)
Creators: name: Sutherland, P. E.
Publisher: name: The Open University
Year: 2010

description: The thesis considers the drive to commemorate within Ulster Protestantism. It focuses on Londonderry between 1859 and 1885 with particular attention paid to the role of evangelicalism, prominent during the relevant period. The assessment is made against the historic backdrop of the Ulster Revival (1859), disestablishment of the Church of Ireland (1869) and the threat of home rule (1880s). In order to gauge more accurately the contribution of religion, a multidisciplinary approach was adopted. Insights from anthropology, political science and sociology were used to complement the primary historical approach to the subject. The subject is approached from two angles, focussing initially on a historical and biographical study of William Johnston (1829-1902), a representative figure who illustrates wider trends and linkages in Ulster's political world and secondly on the city of Londonderry and its anniversary commemorations, and on the important intersection between the two. The discourse from the sermons preached at the 12 August and 18 December commemorations, organised by the Apprentice Boys of Londonderry Association, were analysed using Ninian Smart's Dimensions of the Sacred as an analytical tool and were compared to the discourse in the secular events. This helped to clarify the nature of the outlook held by the protagonists and establish the extent to which it had a religious framework. The catalytic role of evangelicalism seemed evident as the synthesis between Loyalism, Orangeism and evangelicalism was explored against political chronology and in relation to covenantalism. A change in direction and a new political agenda with strong religious conviction became an aspect of Loyalism. This change was reflected in ritual that underwent significant developmenet in the period. This was considered in relation to two important relevant scholarly concepts that related to identity, the 'invention of tradition' and 'civil religion'. The period between 1859 and 1885 proved pivotal in the development of Ulster Protestant cultural identity.

description: In arXiv1312.7267, the first non-trivial example of a Poisson manifold of strong compact type is given. The construction uses the theory of K3 surfaces and results in a Poisson manifold with leaf space $S^1$. We modify the construction to obtain a new class of examples. Specifically, we obtain for each strongly integral affine 2-torus a Poisson manifold of strong compact type with said torus as leaf space.

description: Within the framework of Einstein-Gauss-Bonnet theory in five-dimensional spacetime ($5D$ EGB), we derive the hydrostatic equilibrium equations and solve them numerically to obtain neutron stars for both isotropic and anisotropic distribution of matter. The mass-radius relations are obtained for SLy equation of state, which describes both the solid crust and the liquid core of neutron stars, and for a wide range of the Gauss-Bonnet coupling parameter $α$. More specifically, we find that the contribution of the Gauss-Bonnet term leads to substantial deviations from Einstein gravity. We also discuss that after a certain value of $α$, the theory admits higher maximum masses compared with general relativity, however, the causality condition is violated in the high-mass region. Finally, our results are compared with the recent observations data on mass-radius diagram.

description: It is shown that the hydrodynamic modes of a dilute granular gas of inelastic hard spheres can be identified, and calculated in the long wavelength limit. Assuming they dominate at long times, formal expressions for the Navier-Stokes transport coefficients are derived. They can be expressed in a form that generalizes the Green-Kubo relations for molecular systems, and it is shown that they can also be evaluated by means of $N$-particle simulation methods. The form of the hydrodynamic modes to zeroth order in the gradients is used to detect the presence of inherent velocity correlations in the homogeneous cooling state, even in the low density limit. They manifest themselves in the fluctuations of the total energy of the system. The theoretical predictions are shown to be in agreement with molecular dynamics simulations. Relevant related questions deserving further attention are pointed out.

Triadic transformation and harmonic coherence in the music of Gavin Bryars
Creators: name: Cook, Scott Alexander
Publisher: name: University of British Columbia
Year: 2010

description: Recent developments in music theory have offered new ways of analyzing and interpreting music that uses major and minor triads differently than in traditional dominant-tonic tonality. Riemannian theory, developed and adapted from the dualist theories of Hugo Riemann (1849-1919), is perhaps the most noteworthy example. However, there is still a broad class of triadic compositions that this theory does not satisfactorily describe. In a 2002 article, Julian Hook proposes a family of "Uniform Triadic Transformations" (UTTs) that encompasses Riemannian transformations, along with a variety of other triadic transformations. The pitch classes in a triad other than the root are not explicit in his representation, making his model distinct from neo- Riemannian and other triadic models that focus on triads’ voice-leading and commontone relationships. In this thesis, I demonstrate the applicability of Hook’s model to the analysis of chord progressions in musical passages from two works by the prominent contemporary British composer Gavin Bryars. Specifically, I show how a special simplytransitive subgroup of UTTs can offer understanding and insight into some of Bryars’s compositional practices. I then suggest further extensions of Hook’s theory, which were not explicit in his article, and apply them to a third work by Bryars.

description: Generative adversarial networks (GANs) have attained photo-realistic quality in image generation. However, how to best control the image content remains an open challenge. We introduce LatentKeypointGAN, a two-stage GAN which is trained end-to-end on the classical GAN objective with internal conditioning on a set of space keypoints. These keypoints have associated appearance embeddings that respectively control the position and style of the generated objects and their parts. A major difficulty that we address with suitable network architectures and training schemes is disentangling the image into spatial and appearance factors without domain knowledge and supervision signals. We demonstrate that LatentKeypointGAN provides an interpretable latent space that can be used to re-arrange the generated images by re-positioning and exchanging keypoint embeddings, such as generating portraits by combining the eyes, nose, and mouth from different images. In addition, the explicit generation of keypoints and matching images enables a new, GAN-based method for unsupervised keypoint detection.
Effective Field Theory approach to lepto-philic self conjugate dark matter

description: We study the self conjugate dark matter (DM) particles interacting primarily with the standard model leptons in an effective field theoretical frame work. We consider SM gauge invariant effective contact interactions between the Majorana fermion, real scalar and a real vector DM with leptons by evaluating the Wilson coefficients appropriate for interaction terms upto dimension-8 and obtain constraints on the parameters of the theory from the observed relic density, indirect detection observations and from the DM-electron scattering cross-sections in the direct detection experiments. Low energy LEP data has been used to study sensitivity in the pair production of such low mass $\le$ 80 GeV DM particles. Pair production of DM particles of mass $\ge$ 50 GeV in association with mono-photons at the proposed ILC has rich potential to probe such effective operators.

A New Kinematical Derivation of the Lorentz Transformation and the Particle Description of Light

Subjects: subject: Classical Physics (physics.class-ph)

description: The Lorentz Transformation is derived from only three simple postulates: (i) a weak kinematical form of the Special Relativity Principle that requires the equivalence of reciprocal space-time measurements by two different inertial observers; (ii) Uniqueness, that is the condition that the Lorentz Transformation should be a single valued function of its arguments; (iii) Spatial Isotropy. It is also shown that to derive the Lorentz Transformation for space-time points lying along a common axis, parallel to the relative velocity direction, of two inertial frames, postulates (i) and (ii) are sufficient. The kinematics of the Lorentz Transformation is then developed to demonstrate that, for consistency with Classical Electrodynamics, light must consist of massless (or almost massless) particles: photons.

description: Gas detection around main sequence stars is becoming more common with around 20 systems showing the presence of CO. However, more detections are needed, especially around later spectral type stars to better understand the origin of this gas and refine our models. To do so, we carried out a survey of 10 stars with predicted high likelihoods of secondary CO detection using ALMA in band 6. We looked for continuum emission of mm-dust as well as gas emission (CO and CN transitions). The continuum emission was detected in 9/10 systems for which we derived the discs' dust masses and geometrical properties, providing the first mm-wave detection of the disc around HD 106906, the first mm-wave radius for HD 114082, 117214, HD 15745, HD 191089 and the first radius at all for HD 121191. A crucial finding of our paper is that we detect CO for the first time around the young 10-16 Myr old G1V star HD 129590, similar to our early Sun. The gas seems colocated with its planetesimal belt and its total mass is likely between $2-10 \times 10^{-5}$ M$_\oplus$. This first gas detection around a G-type main-sequence star raises questions as to whether gas may have been released in the Solar System as well in its youth, which could potentially have affected planet formation. We also detected CO gas around HD 121191 at a higher S/N than previously and find that the CO lies much closer-in than the planetesimals in the system, which could be evidence for the previously suspected CO viscous spreading owing to shielding preventing its photodissociation. Finally, we make estimates for the CO content in planetesimals and the HCN/CO outgassing rate (from CN upper limits), which we find are below the level seen in Solar System comets in some systems.

We show that the kinematic formulas for $G$ are determined by the product pairing. Using this result we then show that the algebra $Val^{U(n) }$ is isomorphic to $R[s,t]/(f_{n+1}, f_{n+2})$, where $s,t$ have degrees 2 and 1 respectively, and the polynomial $f_i$ is the degree $i$ term of the power series $\log(1 + s +t)$.

The Maximum Energy and Spectra of Cosmic Rays Accelerated in Active Galactic Nuclei
Creators: name: Uryson, A. V.
Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We computed the energy spectra of the incident (on an air shower array) ultrahigh-energy (E > 4x10^19 eV) cosmic rays (CRs) that were accelerated in nearby Seyfert nuclei at redshifts z<= 0.0092 and in BL Lac objects. For our calculations, we took the distribution of these sources over the sky from catalogs of active galactic nuclei. In accordance with the possible particle acceleration mechanisms, the initial CR spectrum was assumed to be monoenergetic for BL Lac's and a power law for Seyfert nuclei. The CR energy losses in intergalactic space were computed by the Monte Carlo method. The artificial proton statistic was 10^5 for each case considered. The computed spectra of the particles incident on an air shower array agree with the measurements, which indirectly confirms the adopted acceleration models. At energies E>=10^20 eV, the spectrum of the protons from nearby Seyfert nuclei that reached an air shower array closely matches the spectrum of the particles from BL Lac's. BL Lac's are, on average, several hundred Mpc away. Therefore, it is hard to tell whether a blackbody cutoff exists or not by analyzing the shape of the measured spectrum at E>= 5x10^19 eV.

title: Negotiating constructions of success and failure: women in mid-life and formations of subject, subjectivity and identity
Creators: name: McAvoy, Jean Marie
Publisher: name: The Open University
Year: 2009

description: This thesis explores constructions of success and failure for women in mid-life in Britain in the early 21st century. It takes a discursive approach to social psychology, understanding language as social action constituting subjects and subjectivity. Data from 20 interviews, including 4 conducted with women in pairs, supported by loosely structured questionnaires and a collection of photographs of women including celebrities and unknown women, were used to generate talk of selves and others. Key objects marked out as sites of success and failure included family; work-life balance; possession of psychological capitals of happiness, security, and decorum around material affluence; exercise of choice, evaluated as good or bad choice and implicated in responsible citizenship. Such sites were seen to be issues of interactional negotiation as analysis attended to ideological dilemmas and contested positions, to rhetorical negotiations of troubled and untroubled positions, such as dilemmas of adequacy and sufficiency for the passing subject. Engaging with sociological narratives of individualisation and neoliberalism, this psychological study provided an empirical illustration of how these grand narratives appear in mundane talk in the context of constructions of success and failure, with implications for making sense of selves and others. Analysis showed more nuanced deployment of discursive resources than much previous literature suggests: talk was threaded with argumentation and contest. The thesis also considered how discourse studies might take life history and personal order seriously. It presents an empirical analysis of personal order, extending this to interpersonal orders and habits of engagement accruing for subjects in ongoing relationships. It adds to debates on the nature of the psychosocial, with concepts from psychoanalytic psychosocial readings, such as imagination and projection, re-worked empirically as discursive productions embedded in shared resources for making sense of the world, deployments also rooted in sedimented personal history.
Advanced scenarios for ITER operation

description: An international experiment, ITER is proposed as the next essential and critical step on the path to demonstrating the scientific and technological feasibility of fusion energy. ITER would give unique opportunities to explore, in reactor relevant conditions, the physics of α-particle heating, plasma turbulence and turbulent transport, stability limits to the plasma pressure and exhaust of power and particles. Improved understanding of the physical processes occurring in tokamak plasmas give enhanced confidence in ITER achieving its goals. In particular, progress has been made in research to raise the performance of tokamaks, aimed to extend the discharge pulse length towards steady-state operation (advanced scenarios). Advanced scenarios use a modified current density profile, ranging from (i) plasmas that sustain a central region with a flat current density profile (zero magnetic shear), capable of operating stationary at high plasma pressure, to (ii) discharges with an off axis maximum of the current density profile (reversed magnetic shear in the core), able to form internal transport barriers, to increase the confinement of the plasma. The physics of advanced tokamak discharges is described, together with an overview of recent results from different tokamak experiments.

description: We describe the results of experiments and simulations performed with the aim of extending photoelectron spectroscopy with intense laser pulses to the case of molecular compounds. Dimer frame photoelectron angular distributions generated by double ionization of N$_2$-N$_2$ and N$_2$-O$_2$ van der Waals dimers with ultrashort, intense laser pulses are measured using four-body coincidence imaging with a reaction microscope. To study the influence of the first-generated molecular ion on the ionization behavior of the remaining neutral molecule we employ a two-pulse sequence comprising of a linearly polarized and a delayed elliptically polarized laser pulse that allows distinguishing the two ionization steps. By analysis of the obtained electron momentum distributions we show that scattering of the photoelectron on the neighbouring molecular potential leads to a deformation and rotation of the photoelectron angular distribution as compared to that measured for an isolated molecule. Based on this result we demonstrate that the electron momentum space in the dimer case can be separated, allowing to extract information about the ionization pathway from the photoelectron angular distributions. Our work, when implemented with variable pulse delay, opens up the possibility of investigating light-induced electronic dynamics in molecular dimers using angularly resolved photoelectron spectroscopy with intense laser pulses.

description: We present new, simultaneous, multifrequency observations of 45 out of the 55 candidate High Frequency Peakers (HFP) selected by Dallacasa et al. (2000), carried out 3 to 4 years after a first set of observations. Our sub-sample consists of 10 galaxies, 28 stellar objects (``quasars'') and 7 unidentified sources. Both sets of observations are sensitive enough to allow the detection of variability at the 10% level or lower. While galaxies do not show significant variability, most quasars do. Seven of them no longer show the convex spectrum which is the defining property of Gigahertz Peaked Spectrum (GPS)/HFP sources and are interpreted as blazars caught by Dallacasa et al. (2000) during a flare, when a highly self-absorbed component dominated the emission. In general, the variability properties (amplitude, timescales, correlation between peak luminosity and peak frequency of the flaring component) of the quasar sub-sample resemble those of blazars. We thus conclude that most HFP candidates identified with quasars may well be flaring blazars.

description: A supervised diagnosis system for digital mammogram is developed. The diagnosis processes are done by transforming the data of the images into a feature vector using wavelets multilevel decomposition. This vector is used as the feature tailored toward separating different mammogram classes. The suggested model consists of artificial neural networks designed for classifying mammograms according to tumor type and risk level. Results are enhanced from our previous study by extracting feature vectors using multilevel decompositions instead of one level of decomposition. Radiologist-labeled images were used to evaluate the diagnosis system. Results are very promising and show possible guide for future work.

description: We construct a general renormalization group transformation on quantum states, independent of any Hamiltonian dynamics of the system. We illustrate this procedure for translational invariant matrix product states in one dimension and show that product, GHZ, W and domain wall states are special cases of an emerging classification of the fixed points of this coarse--graining transformation.

title: Using innovation and business models to analyse the organisational embedding of travel plans
Creators: name: Roby, Helen
Publisher: name: The Open University
Year: 2010

description: Workplace travel planning began in the UK in the early 1990s. With over ten years of experience in travel plans in the UK, this thesis demonstrates how they have developed, matured and the extent to which they have become embedded into the organisations working practices as a business management tool. This work is distinct from previous research, as it concentrates on the business perspective of travel plans, through a series of in depth interviews within organisations. These interviews were analysed using innovation and business models, such as elements of Rogersï¿½ (2003) Diffusion of Innovations and Mintzberg's (1983) Structure in Fives, Designing Effective Organisations, to explore the impact of the characteristics and structure of an organisation on the embedding of a travel plan. This thesis identified factors that have helped to organisationally embed travel plans. A key finding was to show that the motivations for a travel plan change as it matures, from those of external regulation through the planning process, to internal goals such as corporate responsibility and the environment, business growth and human resources issues. This research has shown the importance of linking travel plans to these organisational goals in the embedding process. However, successful embedding is not easy. A travel plan can either remain siloed within an estates function or become so widely dispersed that the benefits are poorly visible. In either case the travel plan runs the risk of being marginalised or lost. The research has also shown that this process of embedding is reliant on the adaptation of the travel plan to match the culture and working practices within an organisation, and that this process of adaptation can be dependent on the position of the travel planner within a strategic area of the organisation. It is concluded that travel planning policy is too focussed on the early stages of adoption and not enough on growing and maturing travel plans, with the result that they are too narrow, and unlikely to yield the business benefits that will secure their long term future.

The nurses’ attitudes and beliefs questionnaire : a psychometric analysis
Creators: name: Aparicio, Dulce Alexandré
Publisher: name: University of British Columbia
Year: 2010

description: The diverging attitudes among maternity care providers (MCP) are increasingly evident. Caring for women in labour requires collaboration among MCPs. An individual MCP brings a distinct field of expertise and philosophy to his or her practice, which creates the potential for environments with parallel and conflicting attitudes towards birth among MCPs. There is a lack of literature that investigates MCPs’ attitudes. Therefore, a legitimate rationale exists to explore MCPs’ attitudes towards birth. This thesis provides a description of the psychometric testing of a new questionnaire, the Nurses’ Attitudes and Beliefs Questionnaire (NABQ). A cross-sectional design was used to quantitatively investigate the NABQ by (a) assessing internal consistency and inter-item reliability and (b) conducting hypothesis testing and exploratory factor analysis. A convenience sample of nurses from a tertiary care hospital returned 72 NABQs. The internal consistency and inter-item reliability were poor. Of 13 hypotheses, only four were supported. The factor analysis resulted in seven factors with low Cronbach’s alphas. A subset of the sample (six nurses) participated in a focus group to comment on the structure and wording of the NABQ. An inductive content analysis of the data resulted in seven relevant themes and concepts. These themes were: (a) Institutional Constraints and Practice Setting Impede Attitudes; (b) Research Serves as a Weak Reflection of Attitudes; (c) Relevance of the Questions; (d) The NABQ Lacks Context to Identify Attitudes; (e) The NABQ Requires Improvements; (f) Positive and Negative Impression of the NABQ and (g) The NABQ Demonstrates a Biased Attitude Towards Normal Birth. The thesis concludes with a discussion of the quantitative and focus group findings as well as the implications for nursing practice, education and research.
Thermal radiation from magnetic neutron star surfaces

description: We investigate the thermal emission from magnetic neutron star surfaces in which the cohesive effects of the magnetic field have produced the condensation of the atmosphere and the external layers. This may happen for sufficiently cool atmospheres with moderately intense magnetic fields. The thermal emission from an isothermal bare surface of a neutron star shows no remarkable spectral features, but it is significantly depressed at energies below some threshold energy. However, since the thermal conductivity is very different in the normal and parallel directions to the magnetic field lines, the presence of the magnetic field is expected to produce a highly anisotropic temperature distribution, depending on the magnetic field geometry. In this case, the observed flux of such an object looks very similar to a BB spectrum, but depressed in a nearly constant factor at all energies. This results in a systematic underestimation of the area of the emitter (and therefore its size) by a factor 5-10 (2-3).

description: This paper builds upon the research of Corwin and Knizel who proved the existence of stationary measures for the KPZ equation on an interval and characterized them through a Laplace transform formula. Bryc, Kuznetsov, Wang and Wesolowski found a probabilistic description of the stationary measures in terms of a Doob transform of some Markov kernels; essentially at the same time, another description connecting the stationary measures to the exponential functionals of the Brownian motion appeared in work of Barraquand and Le Doussal.
 Our first main result clarifies and proves the equivalence of the two probabilistic description of these stationary measures. We then use the Markovian description to give rigorous proofs of some of the results claimed in Barraquand and Le Doussal. We analyze how the stationary measures of the KPZ equation on finite interval behave at large scale. We investigate which of the limits of the steady states of the KPZ equation obtained recently by G. Barraquand and P. Le Doussal can be represented by Markov processes in spatial variable under an additional restriction on the range of parameters.

description: The aging part $R_{ag}(t,s)$ of the impulsive response function of the two dimensional ferromagnetic Ising model, quenched below the critical point, is studied numerically employing a new algorithm without the imposition of the external field. We find that the simple scaling form $R_{ag}(t,s)=s^{-(1+a)}f(t/s)$, which is usually believed to hold in the aging regime, is not obeyed. We analyse the data assuming the existence of a correction to scaling. We find $a=0.273 \pm 0.006$, in agreement with previous numerical results obtained from the zero field cooled magnetization. We investigate in detail also the scaling function $f(t/s)$ and we compare the results with the predictions of analytical theories. We make an ansatz for the correction to scaling, deriving an analytical expression for $R_{ag}(t,s)$. This gives a satisfactory qualitative agreement with the numerical data for $R_{ag}(t,s)$ and for the integrated response functions. With the analytical model we explore the overall behavior, extrapolating beyond the time regime accessible with the simulations. We explain why the data for the zero field cooled susceptibility are not too sensitive to the existence of the correction to scaling in $R_{ag}(t,s)$, making this quantity the most convenient for the study of the asymptotic scaling properties.

description: We report resonant x-ray scattering data of the orbital and magnetic ordering at low temperatures at the Mn $L_{\rm 2,3}$ edges in \lsmo. The orderings display complex energy features close to the Mn absorption edges. Systematic modeling with atomic multiplet crystal field calculations was used to extract meaningful information regarding the interplay of spin, orbital and Jahn-Teller order. These calculations provide a good general agreement with the observed energy dependence of the scattered intensity {for a} dominant orbital ordering of the $ d_{x^2 - z^2} / d_{y^2 - z^2} $ type. In addition, the origins of various spectral features are identified. The temperature dependence of the orbital and magnetic ordering was measured and displays a strong interplay between the magnetic and orbital order parameters.
