description: Chest X-ray scan is a most often used modality by radiologists to diagnose many chest related diseases in their initial stages. The proposed system aids the radiologists in making decision about the diseases found in the scans more efficiently. Our system combines the techniques of image processing for feature enhancement and deep learning for classification among diseases. We have used the ChestX-ray14 database in order to train our deep learning model on the 14 different labeled diseases found in it. The proposed research shows the significant improvement in the results by using wavelet transforms as pre-processing technique.

description: Multi-frequency radio polarimetry of the diffuse Galactic synchrotron background gives new viewpoints on the Galactic magnetic field. Rotation measure maps reveal magnetic structures on arcminute to degree scales, such as a ring in polarization that we interpret as a magnetic tunnel. A complication using this technique is depolarization across the beam and along the line of sight. The influence of beam depolarization has been estimated using numerical models of the magneto-ionic ISM, through which polarized radiation propagates. The models show that depolarization canals similar to those observed can be caused by beam depolarization, and that the one-dimensional gradients in RM needed to produce these canals are ubiquitous in the medium.

description: This note discusses the interplay between dissipativity and the asymptotics of continuous-time infinite-horizon optimal control problems. We focus on the results on convergence of optimal primal solutions derived in [6]. Moreover, we present a result on the attractivity of the infinite-horizon optimal adjoint trajectories, which is closely related to transversality conditions for infinite-horizon optimal control problems. Proofs and further results can be found in [6].

Reflection and refraction of an electron spin at the junction between two two-dimensional regions with and without spin-orbit interaction

description: We derive the reflection and refraction laws for an electron spin incident from a quasi-two-dimensional medium with no spin-orbit interaction on another with both Rashba and Dresselhaus spin-orbit interaction using only energy conservation. We obtain the well-known result that for an incident angle, there can be generally two different refraction angles for refraction into the two spin eigenstates in the refraction medium, resulting in two different 'spin refractive indices' and two critical angles for total internal reflection. We derive expressions for the spin refractive indices, which are not constant for a given medium but depend on the incident electron's energy. If the effective mass of an electron in the refraction medium is larger than that in the incidence medium, then we show that for some incident electron energies and potential barrier at the interface, the spin refractive index of the incidence medium can lie between the two spin refractive indices of the refraction medium, resulting in only one critical angle. In that case, if the incident angle exceeds that critical angle, then refraction can occur into only one spin eigenstate in the refraction medium. If the system is engineered to make this happen, then it will be possible to obtain a very high degree of spin-polarized injection into the refraction medium. The amplitudes of reflection of the incident spin into its own spin eigenstate and the orthogonal spin eigenstate (due to spin flip at the interface), as well as the refraction amplitudes into the two spin eigenstates in the refraction medium are derived for an incident electron (with arbitrary spin polarization and incident energy) as a function of the angle of incidence.

description: Recent observation of beta decay of 115-In to the first excited level of 115-Sn with an extremely low Q_beta value (Q_beta ~ 1 keV) could be used to set a limit on neutrino mass. To give restriction potentially competitive with those extracted from experiments with 3-H (~2 eV) and 187-Re (~15 eV), atomic mass difference between 115-In and 115-Sn and energy of the first 115-Sn level should be remeasured with higher accuracy (possibly of the order of ~1 eV).

The role of Akt in AMPA receptor insertion and LTP
Creators: name: Yan, Yi
Publisher: name: University of British Columbia
Year: 2011

description: It has been widely accepted that long-term potentiation (LTP) in the hippocampal CA1 region mostly results from increased insertion of post-synaptic α-amino-3-hydroxy-5-methyl-isoxazole-4-propionic acid receptors (AMPARs). The previous study in our lab has shown that activation of phosphatidylinositol 3-kinase (PI3K) by selective stimulation of synaptic N-methyl-D-aspartate receptors (NMDARs) is required for the increased cell surface expression of AMPARs and the consequent LTP. However, the following signaling pathways still remain unknown. In the present study, the involvement of Akt, the primary downstream protein kinase of PI3K, was examined with a combination of electrophysiological, biochemical and molecular biological techniques. The study found that Akt is required for the post-synaptic AMPAR insertion and LTP. Furthermore, the threonine 840 (Thr840) on GluRl C-tail was identified as a novel Akt phosphorylation site, suggesting a potential mechanism by which Akt contributes to AMPAR incorporation and LTP.

description: South Australia's natural resources are fundamental to the economic and social wellbeing of the state. One of the state's most precious natural resources, water is a basic requirement of all living organisms and is one of the essential elements ensuring biological diversity of life at all levels. In pristine or undeveloped situations, the condition of water resources reflects the equilibrium between rainfall, vegetation and other physical parameters. Development of these resources changes the natural balance and may cause degradation. If degradation is small, and the resource retains its utility, the community may assess these changes as being acceptable. However, significant stress will impact on the ability of a resource to continue to meet the needs of users and the environment. Understanding the cause and effect relationship between the various stresses imposed on the natural resources is paramount to developing effective management strategies. Reports of investigations into the availability and quality of water supplies throughout the state aim to build upon the existing knowledge base, enabling the community to make informed decisions concerning the future management of the natural resources, thus ensuring conservation of biological diversity.

Spectral strengthening of a theorem on transversal critical graphs
Creators: name: Liu, Muhuo
name: Gu, Xiaofeng
Publisher: name: arXiv
Year: 2020
Subjects: subject: Combinatorics (math.CO)
subject: FOS: Mathematics

description: A transversal set of a graph $G$ is a set of vertices incident to all edges of $G$. The transversal number of $G$, denoted by $τ(G)$, is the minimum cardinality of a transversal set of $G$. A simple graph $G$ with no isolated vertex is called $τ$-critical if $τ(G-e) < τ(G)$ for every edge $e\in E(G)$. For any $τ$-critical graph $G$ with $τ(G)=t$, it has been shown that $|V(G)|\le 2t$ by Erdős and Gallai and that $|E(G)|\le {t+1\choose 2}$ by Erdős, Hajnal and Moon. Most recently, it was extended by Gyárfás and Lehel to $|V(G)| + |E(G)|\le {t+2\choose 2}$. In this paper, we prove stronger results via spectrum. Let $G$ be a $τ$-critical graph with $τ(G)=t$ and $|V(G)|=n$, and let $λ_1$ denote the largest eigenvalue of the adjacency matrix of $G$. We show that $n + λ_1\le 2t+1$ with equality if and only if $G$ is $tK_2$, $K_{s+1}\cup (t-s)K_2$, or $C_{2s-1}\cup (t-s)K_2$, where $2\leq s\leq t$; and in particular, $λ_1(G)\le t$ with equality if and only if $G$ is $K_{t+1}$. We then apply it to show that for any nonnegative integer $r$, we have $n\left(r+ \frac{λ_1}{2}\right) \le {t+r+1\choose 2}$ and characterize all extremal graphs. This implies a pure combinatorial result that $r|V(G)| + |E(G)| \le {t+r+1\choose 2}$, which is stronger than Erdős-Hajnal-Moon Theorem and Gyárfás-Lehel Theorem. We also have some other generalizations.

description: General relativity may seem very different from quantum theory, but work on quantum gravity has revealed a deep analogy between the two. General relativity makes heavy use of the category nCob, whose objects are (n-1)-dimensional manifolds representing "space" and whose morphisms are n-dimensional cobordisms representing "spacetime". Quantum theory makes heavy use of the category Hilb, whose objects are Hilbert spaces used to describe "states", and whose morphisms are bounded linear operators used to describe "processes". Moreover, the categories nCob and Hilb resemble each other far more than either resembles Set, the category whose objects are sets and whose morphisms are functions. In particular, both Hilb and nCob but not Set are *-categories with a noncartesian monoidal structure. We show how this accounts for many of the famously puzzling features of quantum theory: the failure of local realism, the impossibility of duplicating quantum information, and so on. We argue that these features only seem puzzling when we try to treat Hilb as analogous to Set rather than nCob, so that quantum theory will make more sense when regarded as part of a theory of spacetime.

title: Nihilism and modernity: political response in a godless age
Creators: name: Glassford, John
Publisher: name: The Open University
Year: 1999

description: In this thesis I argue that following Hegel's commitment to both political philosophy and political theory, Max Stirner, Karl Marx and Friedrich Nietzsche take flight from doing political theory in the 'Western' tradition. I demonstrate that Stirner, Marx and Nietzsche all use their own respective notions of political philosophy to criticise the very idea of doing political theory per . re. The evidence for this is to be found in both their refusal to do political theory and in their notions of prophetic agency. I further argue that this development is bound-up with their particular responses to the post-Hegelian milieu of which they were a part. As such, Stirner, Marx and Nietzsche all subscribed to a novel form of secularised eschatology. Although there have been studies of this secularisation thesis before, most notably by Karl Löwith, and groundbreaking though this study is, it is related to the difficult period in which in was written (the 1930's and 40's). Löwith for example, is concerned with the impact that eschatological thought has on the formation of totalitarian regimes more generally. As a result, such studies, which might encapsulate Hegel's own thought, are often rejected as but a species of the kind of eschatological literature which are also held to be necessarily repressive. However, in this thesis I point to an important cleavage between Hegel and his followers: Hegel, despite his eschatological outlook, remains firmly tied to the traditional 'Western' canon in so far as we see his commitment and application to doing political theory, whether descriptive or normative, and as such it is also demonstrably supported by his own political philosophy. Whereas in the case of Stirner, Marx and Nietzsche, their own eschatological projects respectively, are used as weapons in the war against political theory. I demonstrate that this historic cleavage occurs because Stirner, Marx and Nietzsche read eschatology as primarily prophetic and forward looking while Hegel's own eschatology remains ex events. The former look to legitimating particular historical agencies of change while Hegel continues to regard the potential multiplicity's of all political agency from within the most promising liberal institutions of modern society.
title: Biogeochemistry of photosymbiosis in host tissues and skeletons of the species Tridacna
Creators: name: Gilmour, Mabs Ann
Publisher: name: The Open University
Year: 2000

description: Algal/invertebrate endosymbiose are common in the marine environment and appear to be nutritional in nature. The giant Tridacnid clams form a mutualistic extracellular endosymbiosis with dinoflagellate algae (zooxanthellae) of the species Symbiodiniunt microadriaticum. The large size of the Tridacnids is generally attributed to the nutritional role of their endosymbionts. This thesis examines the nature and mechanisms by which important biochemicals, such as lipids, are translocated from the symbionts to the host. Methodologies have been developed to enable the determination of the carbon isotope composition of individual saturated and polyunsaturated fatty acids to enable natural abundance isotopic variations in these compounds to be investigated in the Tridacnid-algal symbiosis. Compound specific isotope analysis of fatty acids in different species of Tridacnids, their zooxanthellae and non-symbiotic species reveal that several fatty acids are apparently directly translocated from algae to host. Evidence is presented for the synthesis of fatty acids from acetate by the clam. Carbon isotopic data also reveal that carbon limitation may play a role in lipid metabolsim in giant clams. Compound specific isotope analysis has also been used to investigate the contribution of translocated compounds during a diel cycle in clam haemolymph and reveals that concentrations of key metabolites vary over the diel cycle as a function of irradiance. The cyclic sugar alcohol scyllo-inositol was detected in clam haemolymph, which may be related to osmoregulation in the clam or to a signalling role in cell proliferation. Oxygen and carbon stable isotope compositions and strontium abundances of shell carbonate are examined in several clams subjected to varying degrees of phosphate and ammonium nutrient supplementation to investigate the relationship between growth rate and stable isotope compositions and strontium contents.
Performance improvements in Stirling cycle machines by a modified appendix gap geometry

description: In this contribution, the optimization potential of the seal geometry in Stirling machines is explored both numerically and analytically, leading to a significant reduction of the related losses which are often referred to as appendix gap losses. These are induced by the narrow gap between the displacer and the cylinder and have mostly been underestimated so far. A recent experimental investigation revealed large optimization potentials by reduction of the seal and cylinder wall diameter near the seal, resulting in reduced appendix gap losses and further indirect positive effects. In this work, these experimental findings could be reproduced by a one-dimensional differential simulation model at a fully satisfyingaccuracy. Furthermore, these investigations reveal that the optimum geometry is largely machine-dependent. To provide an easily applicable design rule for this optimum geometry, a refined analytical model for the mass flow at the top of the gap is derived, which is based on a phasor analysis and a linearized mass balance that also accounts for changes in the spatial mean gas temperature in the gap. The optimum design predicted by this model is very close to numerical optimization results and sufficiently accurate under practical aspects. Furthermore, this model contributes to a better theoretical understanding of the loss mechanisms in the gap.

description: We report a throughout analysis of the entanglement entropies related to different symmetry sectors in the low-lying primary excited states of a conformal field theory (CFT) with an internal U(1) symmetry. Our findings extend recent results for the ground state. We derive a general expression for the charged moments, i.e. the generalised cumulant generating function, which can be written in terms of correlation functions of the operator that define the state through the CFT operator-state correspondence. We provide explicit analytic computations for the compact boson CFT (aka Luttinger liquid) for the vertex and derivative excitations. The Fourier transform of the charged moments gives the desired symmetry resolved entropies. At the leading order, they satisfy entanglement equipartition, as in the ground state, but we find, within CFT, subleading terms that break it. Our analytical findings are checked against free fermions calculations on a lattice, finding excellent agreement. As a byproduct, we have exact results for the full counting statistics of the U(1) charge in the considered excited states.
title: The codification of pitch organisation in the early atonal works of Alban Berg
Creators: name: Gates, Bernard
Publisher: name: The Open University
Year: 1999

description: There has recently been an unprecedented flurry of interest in the music of Alban Berg, although responses towards his first atonal works remain relatively sparse. This thesis presents detailed analyses of the pieces written between 1909 and 1913: the fourth Opus 2 song, the String Quartet, Opus 3, the Altenberglieder, Opus 4, and the Four Pieces for clarinet and piano, Opus 5. It also provides a systematically-developed theoretical framework for each.

Analyses of the String Quartet and the Altenberglieder explore the development and transformation of motives, and identify different aggregate systems which temporarily limit the range or arrangement of pitches to certain defined scales, such as the whole-tone or octatonic, or to the interaction between different scales or different versions of the same scale. The Four Pieces for clarinet and piano require a rather different form of investigation, into the interrelationship between intervallic cell and pitch-class set and genera-based material. A factor consistent across all four works is the presence of symmetrical pitch structures such as interval cycles, wedge formations and transpositionally invariant sets. The analyses are based on these foundations, while extending beyond them to incorporate related asymmetries and more complex relations and transformations.

Any codification of pitch organisation in these early atonal works of Berg has to contend with their particular complexities of expression and absence of any calculated method; this thesis nevertheless proposes several forms of categorisation which can correlate with many of the miriad pitch structures in the music, and which can in turn supply models for some of the discernible interrelational structural processes.

description: Many species are unsustainable at small population densities (Allee Effect), i.e., below a threshold named Allee threshold, the population decreases instead of growing. In a closed local population, environmental fluctuations always lead to extinction. Here, we show how, in spatially extended habitats, dispersal can lead to a sustainable population in a region, provided the amplitude of environmental fluctuations is below an extinction threshold. We have identified two types of sustainable populations: high-density and low-density populations (through a mean-field approximation, valid in the limit of large dispersal length). Our results show that patches where population is high, low or extinct, coexist when the population is close to global extinction (even for homogeneous habitats). The extinction threshold is maximum for characteristic dispersal distances much larger than the spatial scale of synchrony of environmental fluctuations. The extinction threshold increases proportionally to the square root of the dispersal rate and decreases with the Allee threshold. The low-density population solution can allow understanding difficulties in recovery after harvesting. This theoretical framework provides a novel approach to address other factors, such as habitat fragmentation or harvesting, impacting population resilience to environmental fluctuations.

description: We investigate how the walls of cylindrical capillaries affect the velocity of rising gas bubbles of various diameters. Of course, as the capillary diameter increases, the velocity of the rising bubble will approach the case of free rising. Such systematic experiments on the bubble rise in capillaries, in which the ratio of bubble diameter and capillary diameter is varied from one towards smaller values, can hardly be found in literature. Experiments within the system water/air have been conducted in stagnant water and will be discussed in this paper.

title: Conflicting discourses: occupational segregation in computer programming
Creators: name: Fitzsimons, Annette
Publisher: name: The Open University
Year: 1999

description: This thesis explores issues round gender and job segregation which emerged during a qualitative study of the different work experiences and attitudes of over fifty female and male computer programmers, in a number of computer software companies and in two internationally renowned manufacturing organizations. The aim of this thesis is to demonstrate the emergence of a sexual division of labour in this occupation and thus illustrate the process of segregation. It explores a qualitative approach to the study of vertical segregation in the computing industry amongst computer programmers. It uses Foucault's concept of discourse to suggest that a number of discourses are productive of gender segregation at work.

By choosing an appropriate form for the metric function representing the radius of the 2-sphere, we solve for the 3-form field and its potential. Using the obtained solution, we construct an interior black hole spacetime which is everywhere regular. The singularity is replaced with a Nariai-type spacetime, whose topology is $\text{dS}_2 \times \text{S}^2$, in which the radius of the 2-sphere is constant. So long as the interior continues to expand indefinitely, the geometry becomes essentially compactified. The 2-dimensional de Sitter geometry appears despite the negative potential of the 3-form field. Such a dynamical compactification could shed some light on the origin of de Sitter geometry of our Universe, exacerbated by the Swampland conjecture. In addition, we show that the spacetime is geodesically complete. The geometry is singularity-free due to the violation of the null energy condition.

description: We present radio polarimetric observations of a test region for the Southern Galactic Plane Survey (SGPS), a radio survey in the Galactic plane in HI and polarized continuum at 1.4 GHz with the Australia Telescope Compact Array (ATCA) and the Parkes 64m dish. Ubiquitous structure in linearly polarized intensity is often uncorrelated with structure in total intensity, indicating Faraday rotation and depolarization. The one-dimensional second order structure function of rotation measure for different position angles of the distance lag shows a very shallow slope of the structure function on small scales and an anisotropy in the slope on large scales. The anisotropy on large scales is indicative of a gradient or large filament across the field. The shallow slope can be explained by contributions of two separated Faraday screens. Assuming that the two Faraday screens are the local and Carina spiral arms, the structure function suggests an outer scale of structure in the local arm of about 2 pc. This scale is similar to the typical scale of a Stroemgren sphere of a B1-2 star. Therefore, we suggest that HII regions possibly dominate the scale of structure in spiral arms.

description: We study the reconstruction of overdensity maps of galaxies as function of redshift in the range $0 < \mathrm z < 0.8$ using data from 1-m Schmidt Telescope of Byurakan Astrophysical Observatory (Armenia) in 16 medium band $\sim 250$ A and four broad band (u,g,r,i) filters. The data used in this work homogeneously cover $2.39$ sq. deg with accurate photometric redshiftss, down to $\mathrm R < 23$ mag (AB). We reconstructed the density contrast maps for the whole galaxy sample of the HS 47.5-22 ROSAT field in narrow slices for full range of redshifts. We select groups and clusters of galaxies with adaptive kernel based on density peaks which are larger than two times the mean density. The reconstructed overdensity field of galaxies consists of cluster-like structures outlining void-like regions for full redshift range $0 \leq \mathrm z \leq 0.8$. We detect known galaxy clusters in this field with software specially developed for this project. This gives us a possibility to study how star formation properties and galaxy morphology depend on the environments of the galaxies in this field.

description: Existing traffic flow forecasting approaches by deep learning models achieve excellent success based on a large volume of datasets gathered by governments and organizations. However, these datasets may contain lots of user's private data, which is challenging the current prediction approaches as user privacy is calling for the public concern in recent years. Therefore, how to develop accurate traffic prediction while preserving privacy is a significant problem to be solved, and there is a trade-off between these two objectives. To address this challenge, we introduce a privacy-preserving machine learning technique named federated learning and propose a Federated Learning-based Gated Recurrent Unit neural network algorithm (FedGRU) for traffic flow prediction. FedGRU differs from current centralized learning methods and updates universal learning models through a secure parameter aggregation mechanism rather than directly sharing raw data among organizations. In the secure parameter aggregation mechanism, we adopt a Federated Averaging algorithm to reduce the communication overhead during the model parameter transmission process. Furthermore, we design a Joint Announcement Protocol to improve the scalability of FedGRU. We also propose an ensemble clustering-based scheme for traffic flow prediction by grouping the organizations into clusters before applying FedGRU algorithm. Through extensive case studies on a real-world dataset, it is shown that FedGRU's prediction accuracy is 90.96% higher than the advanced deep learning models, which confirm that FedGRU can achieve accurate and timely traffic prediction without compromising the privacy and security of raw data.

description: We perform a microscopic evaluation of nuclear GPDs for spin-0 nuclei in the framework of the Walecka model. We demonstrate that the meson (non-nucleon) degrees of freedom dramatically influence nuclear GPDs, which is revealed in the non-trivial and unexpected A-dependence of DVCS observables. In particular, we find that the first moment of the nuclear D-term, d_A(0) ~ A^2.26, which confirms the earlier prediction of M.Polyakov. We find that in the HERMES kinematics, contrary to the free proton case, the nuclear meson degrees of freedom in large nuclei enhance the nuclear DVCS amplitude which becomes comparable to the Bethe-Heitler amplitude, and, thus, give the non-trivial A-dependence to the DVCS asymmetries: as a function of the atomic number the beam-charge asymmetry increases whereas the beam-spin asymmetry decreases slowly.

Transcoding the system information from the DVB-MHP to Blu-ray format in real-time

description: The demand for interactive services in the broadcast world is rapidly increasing. The new-generation packaged medium, the Blu-ray system is designed to support many sophisticated interactivities. Since most interactive TV programs have the Digital Video Broadcast - Multimedia Home Platform (DVB-MHP) format, this study addresses how such programs could be played by the Blu-ray system in real-time. Despite the fact that both the DVB-MHP and the Blu-ray standards are based on the MPEG-2 standard for video related applications and on the Globally Executable MHP (GEM) standard for Java-based interactivity, DVB-MHP and Blu-ray have several differences that make the two systems incompatible. One of the main challenges in realizing this compatibility is the conversion of the "system information" data. These data carry the information about the broadcasting programs and services. This thesis first analyzes the differences in the system information between the two standards, DVB-MHP and Blu-ray, mainly what information each standard requires, where they are stored, and how they are organized. We then propose methods that transcode this information efficiently, i.e., in real-time. Thus, to demultiplex the data needed for generating the Blu-ray system information, we propose a scheme that is 33% faster than the conventional method. To extract the needed information from the DVB-MHP video stream, we propose an efficient search algorithm. Finally, an improved transcoder structure is proposed. This transcoder only transcodes the incoming system information or its updated versions and at the same time keeps the rate of this information transmitted to the Blu-ray system the same as that in the DVB-MHP system.

title: The role of reversal theory in moderating occupational stress in British police officers, special constables and civilian support staff
Creators: name: Grover, Jennifer J.
Publisher: name: The Open University

description: The causes and consequences of police stress has received considerable research interest. Reversal theory postulates some individuals may inherently require higher (Le. paratelic) arousal levels, compared with those seeking lower (Le. telic) arousal levels. This present study investigated: (i) psychological problems experienced between British police officers, special (voluntary) police and civilian support staff; (ii) telic and paratelic dominance; (iii) use of humour; (iv) dimensions of police humour; and (v) predictors of police psychological problems, telic dominance and humour use. A mixed, cross-sectional survey design was employed. Questionnaires were sent to all police officers, support staff and specials (N = 373) within one division of a provincial police service. Participants completed the following measures: (i) Coping Humour Scale (CHS); (ii) Multi-dimensional Sense of Humour Scale (MSHS); (iii) Telic Dominance Scale (TDS); and (v) Employee Assistance Program Inventory (EAPI). Questionnaires were returned from 191 participants (51% response rate). For overall CHS and MSHS scores, no significant differences between groups were found; although police gender differences were significant. MSHS police dimensions deviated from previous samples. Overall TDS scores were significantly higher for specials. For all three groups, EAPI subscale scores were normative, but with significantly higher substance use reported by police. Police EAPI scores were generally significantly higher, indicative of greater psychological difficulties. Predictors of police psychological problems, TDS, CHS and MSHS scores are reported. These results suggest that police may have a paratelic dominance, in which humour provides a valuable and adaptive mechanism for pOlice stress. Clinical implications are discussed in light of these results.

description: Color polarizabilities of the neutron are extracted from data on the lowest moment of the spin-dependent $g_1$ structure function. New data in the resonance region from Jefferson Lab at $Q^2 \alt 1$ GeV$^2$, in combination with world data at higher $Q^2$, allow a systematic determination of the $1/Q^2$ corrections, and provide the first constraints on $1/Q^4$ corrections. The results suggest that higher-twist effects in the neutron are small, and that quark-hadron duality may be approximately valid, even down to $Q^2 \sim 1$ GeV$^2$.
