description: We study the Glauber dynamics of Ising spin models with random bonds, on finitely connected random graphs. We generalize a recent dynamical replica theory with which to predict the evolution of the joint spin-field distribution, to include random graphs with arbitrary degree distributions. The theory is applied to Ising ferromagnets on randomly diluted Bethe lattices, where we study the evolution of the magnetization and the internal energy. It predicts a prominent slowing down of the flow in the Griffiths phase, it suggests a further dynamical transition at lower temperatures within the Griffiths phase, and it is verified quantitatively by the results of Monte Carlo simulations.

description: When salts are added to water, the viscosity generally increases suggesting the ions increase the strength of the water's hydrogen-bond network. However, infrared pump-probe measurements on electrolyte solutions have found that ions have no influence on the rotational dynamics of water molecules implying no enhance-ment or breakdown of the hydrogen-bond network. Here we report optical Kerr-effect and dielectric relaxa-tion spectroscopic measurements, which have enabled us to separate the effects of rotational and transitional motions of the water molecules. These data show that electrolyte solutions behave like a supercooled liquid approaching a glass transition in which rotational and translational molecular motions are decoupled. It is now possible to understand previously conflicting viscosity data, nuclear magnetic resonance relaxation, and ultrafast infrared spectroscopy in a single unified picture.

description: Exposure of highly oriented pyrolytic graphite to bromine vapor gives rise to in-plane charge conductivities which increase monotonically with intercalation time toward values (for ~6 at% Br) that are significantly higher than Cu at temperatures down to 5 K. Magnetotransport, optical reflectivity and magnetic susceptibility measurements confirm that the Br dopes the graphene sheets with holes while simultaneously increasing the interplanar separation. The increase of mobility (~ 5E4 cm^2/Vs at T=300 K) and resistance anisotropy together with the reduced diamagnetic susceptibility of the intercalated samples suggests that the observed supermetallic conductivity derives from a parallel combination of weakly-coupled hole-doped graphene sheets.

description: Typical WLAN based indoor positioning systems take the received signal strength (RSS) as the major information source. Due to the complicated indoor environment, the RSS measurements are hard to model and too noisy to achieve a satisfactory 3-D accuracy in multi-floor scenarios. To enhance the performance of WLAN positioning systems, extra information sources could be integrated. In this paper, a Bayesian framework is applied to fuse multi-information sources and estimate the spatial and time varying parameters simultaneously and adaptively. An application of this framework, which fuses pressure measurements, a topological building map with RSS measurements, and simultaneously estimates the pressure sensor bias, is investigated. Our experiments indicate that the localization performance is more accurate and robust by using our approach.
Studies on the structure of human haptoglobin chain
Creators: name: Hew, Choy-Leong
Publisher: name: University of British Columbia

description: Haptoglobins are a group of glycoproteins found in normal human serum and are capable of binding hemoglobin both in vivo and in vitro. Haptoglobin 2-1, one of the common haptoglobin phenotypes was isolated in large quantity from the ascites fluid. Upon reduction and alkylation in the presence of 8 M urea, haptoglobin dissociates into two different classes of polypeptide chains, the α and the β chains. The haptoglobin β chain, which is the larger and the only component that contains carbohydrate has been studied in the present investigation. The homogeneity of this polypeptide chain was examined using different criteria, such as DEAE-cellulose chromatography, gel filtration chromatography, urea starch gel and SDS disc gel electrophoresis. The β chain was found to be homogeneous as judged by the above different criteria. The amino acid composition and carbohydrate composition as well as the N-terminal amino acid were determined. The β chain isolated in the -S-methyl-carboxyamide form was extensively aggregated. However, upon chemical modification using succinic anhydride, the modified β chain was completely disaggregated, and it was possible to determine the accurate molecular weight of the β chain using this succinyl β chain. In order to elucidate the primary structure of the β chain, a cyanogen bromide reaction, which cleaved selectively at the methionine residues was performed. Though this cleavage was incomplete in β chain, three fragments were isolated and characterized. The amino acid sequence of the N-terminal region, the α, β interchain disulfide region and the carbohydrate attachment site region were determined. The alignment of some of the cyanogen bromide cleavage fragments were achieved using the methionine peptides from a tryptic digest of the β chain to overlap these fragments. The methionine peptides were isolated by a selective diagonal paper electrophoretic technique. The linkage between the protein and the carbohydrate in haptoglobin was established to be an aspartamido-glycosyl linkage This was demonstrated by the resistance of the linkage under mild alkali treatment and the actual isolation of an aspartic-carbo-hydrate complex. A different approach was taken to determine the primary structure of the β chain. The β chain was maleylated at its e-amino lysyl groups with maleic anhydride and later digested with trypsin. The maleylated fragments were isolated and partially characterized. Furthermore, five groups of arginine peptides were isolated. An overall structure of the β chain was deduced from the studies of the cyanogen bromide peptides, methionine peptides, tryptic maleylated peptides and the arginine peptides.

description: Schutzenberger's theorem for the ordinary RSK correspondence naturally extends to Chen et. al's correspondence for matchings and partitions. Thus the counting of bilaterally symmetric $k$-noncrossing partitions naturally arises as an analogue for involutions. In obtaining the analogous result for 3-noncrossing partitions, we use a different technique to develop a Maple package for 2-dimensional vacillating lattice walk enumeration problems. The package also applies to the hesitating case. As applications, we find several interesting relations for some special bilaterally symmetric partitions.

The mere real thing and beyond : an alternative perspective of everyday life through the appropriation of commonplace things in the context of contemporary visual arts entertainment
Creators: name: Lee, Stone Hsutung
Publisher: name: University Of Tasmania
Year: 2023

description: This studio-based research project examines the perception and meanings of ordinary objects as a way to understand our existence. My argument has focused on the meaninglessness of life and existence as that experience itself can easily appear out of the encounters of our everyday life. I have attempted to establish a thesis about the ordinariness of meaning through the primacy of objects. The only meaning is the meaning of the ordinary and the everyday, and that is essentially the fragile and transient. The aims of this research are to bring the ordinary object, in its multiplicity of being, its transience and fragility, to the centre of attention; to make us aware of the fragility, transience and multiplicity of meanings, of language and of the real; to exhibit a conception of art through the deconstruction of things, and in doing so bring into question the relationship between art and life; and to create a body of work that embodies a certain way of understanding human life. The exegesis comprises six chapters with each chapter testing one aspect of my research. I have explored my position as a contemporary artist and set out my worldview for a solution of survival. I considered the definition of art in relation to contemporary circumstances and explained why appropriation and collage are central elements in my approach. The research has also been set in a context enabling the critique of other artists' works that have experienced similar attitudes and themes. I have demonstrated that art reveals the truth of existence and helps us to perceive and inhabit this physical world. Through an all-embracing attitude toward things, I claim we are able to arrive at a state of understanding and then confidently project the potentiality of all being.

description: Bezrukavnikov (later together with Arinkin) recovered the work of Deligne defining perverse $t$-structures for the derived category of coherent sheaves on a projective variety. In this text we prove that these $t$-structures can be obtained through tilting torsion theories as in the work of Happel, Reiten and Smalø. This approach proves to be slightly more general as it allows us to define, in the quasi-coherent setting, similar perverse $t$-structures for certain noncommutative projective planes.

description: We compared accuracy for breast cancer (BC) risk stratification of a new fully automated system (DenSeeMammo-DSM) for breast density (BD) assessment to a non-inferiority threshold based on radiologists' visual assessment. Pooled analysis was performed on 14,267 2D mammograms collected from women aged 48-55 years who underwent BC screening within three studies: RETomo, Florence study and PROCAS. BD was expressed through clinical Breast Imaging Reporting and Data System (BI-RADS) density classification. Women in BI-RADS D category had a 2.6 (95% CI 1.5-4.4) and a 3.6 (95% CI 1.4-9.3) times higher risk of incident and interval cancer, respectively, than women in the two lowest BD categories. The ability of DSM to predict risk of incident cancer was non-inferior to radiologists' visual assessment as both point estimate and lower bound of 95% CI (AUC 0.589; 95% CI 0.580-0.597) were above the predefined visual assessment threshold (AUC 0.571). AUC for interval (AUC 0.631; 95% CI 0.623-0.639) cancers was even higher. BD assessed with new fully automated method is positively associated with BC risk and is not inferior to radiologists' visual assessment. It is an even stronger marker of interval cancer, confirming an appreciable masking effect of BD that reduces mammography sensitivity.

description: In many technical systems, the system state, which is to be controlled, is not directly accessible, but has to be estimated from observations. Furthermore, the uncertainties arising from this procedure are typically neglected in the controller. To remedy this deficiency, in this paper, we present a novel approach to stochastic nonlinear model predictive control (NMPC) for heavily noise-affected systems with not directly accessible, i.e., hidden states, extending the stochastic NMPCframework presented in [1]. An important property of our novel method is that, in contrast to classical approaches, time-variant system and measurement equations as well as time-variant step rewards can be considered. Extending the techniques from [1] by introducing virtual future observations and combining this with a novel tree search algorithm, called probabilistic branch-and-bound search (PBAB), a solution with a feasible computational demand of the challenging problem is possible.

description: Rotavirus genomes are distributed between 11 distinct RNA molecules, all of which must be selectively copackaged during virus assembly. This likely occurs through sequence-specific RNA interactions facilitated by the RNA chaperone NSP2. Here, we report that NSP2 autoregulates its chaperone activity through its C-terminal region (CTR) that promotes RNA-RNA interactions by limiting its helix-unwinding activity. Unexpectedly, structural proteomics data revealed that the CTR does not directly interact with RNA, while accelerating RNA release from NSP2. Cryo-electron microscopy reconstructions of an NSP2-RNA complex reveal a highly conserved acidic patch on the CTR, which is poised toward the bound RNA. Virus replication was abrogated by charge-disrupting mutations within the acidic patch but completely restored by charge-preserving mutations. Mechanistic similarities between NSP2 and the unrelated bacterial RNA chaperone Hfq suggest that accelerating RNA dissociation while promoting intermolecular RNA interactions may be a widespread strategy of RNA chaperone recycling.
The imaginative development of Edwin Muir
Creators: name: Anderson, Rosemary Margaret
Publisher: name: University of British Columbia
Year: 2011

description: The poems and novels of Edwin Muir are closely linked by their themes and images, and the insights reached in the mature poems resolve the problems implicit in the earlier, less successful work. Despite its thematic unity, however, Muir’s poetry is not the expression of a conscious, systematic view of the world, but a sustained attempt to create a sense of the depths inherent in human experience. His poems aspire not towards a statement of truth, but towards a sense of total presence, in which being is infused with consciousness. The experience of presence is reached through the imaginative experience of absence, when the barriers between the mind and the world seem insurmountable. The thesis examines the growth and resolution of this dualistic vision of life, with its roots in Muir’s early experience. His years of poverty in Glasgow forced him to see man's misery and degradation, yet in his dreams he experienced states of limitless union and freedom, which seemed to show that the human being is not bound by time and circumstance. Muir's creative phase began in Germany, when his reading of German poets and novelists helped him to set his experience of suffering and deprivation within an imaginative vision of life.

description: We design three-dimensional (3D) metallic nanowire media with different structures and numerically demonstrate that they can be homogeneous effective indefinite anisotropic media by showing that their dispersion relations are hyperbolic. For a finite slab, a nice fitting procedure is exploited to obtain the dispersion relations from which we retrieve the effective permittivities. The pseudo focusing for the real 3D wire medium agrees very well with the homogeneous medium having the effective permittivity tensor of the wire medium. Studies also show that in the long-wavelength limit, the hyperbolic dispersion relation of the 3D wire medium can be valid even for evanescent modes.

Urban renewal in Canada : a postmortem
Creators: name: Lowden, James David
Publisher: name: University of British Columbia
Year: 2011

description: Major amendments were made to the National Housing Act (1954) Section 23 in 1964. These altered the scope of urban renewal which had been utilized for the ten previous years. The major features of the revised legislation included cost-sharing by Central Mortgage and Housing Corporation, as one member of a tripartie partnership, in the following undertakings: a) the preparation of urban renewal studies, b) the preparation of urban renewal schemes, c) the implementation of the resulting projects including - i. the cost of acquiring and clearing property, ii. the upgrading of public services such as roads, sewers and watermains. The reuse of the cleared land was at the discretion of the municipality and could be retained by the latter or sold to private interests. This program operated until October 1968, when it was halted upon the request of the Federal Minister responsible for Central Mortgage and Housing Corporation. To that date $168 million had been spent by the Federal Government on the above mentioned aspects of the program and there existed a potential commitment of nearly $300 million. The hypothesis underlying the examination of the material was that the amendments were overambitious, in that the objectives were not clearly specified and the scale of the public commitment was open ended. The result was a range of potential projects which could not be adequately administered through the operating policies of Central Mortgage and Housing Corporation. By way of a sub-hypothesis, it has been contended that a major factor in the urban renewal process was the discord between the expansive but ill-defined objectives and the detailed administrative policies to carry out the program. In particular, the following elements were noted: a) Urban renewal, for all communities and all land uses, was carried out within a single, universally applied set of administrative policies, b) The economic terms of reference lacked sophistication. This prejudiced the viability of the proposed projects, especially in terms of fostering private development in renewal areas. c) The bureaucratization of the program produced an administration which was more involved in the process than the product of urban renewal. Concomitant factors were excessive time lags and an inefficient use of staff. These inadequacies, contributing factors to the low achievement level of the program, led to its evaluation for the first time in 1968 by CMHC. The result was the aforementioned discontinuation of the program. To the extent that CMHC has been considering a reversion to the pre 1964 position in urban renewal, that is, a residentially oriented program, it was felt that the changes were overambitious. This presentation has attempted to examine the Canadian urban renewal program between 1964 and 1968 and, within the confines of the material documented, the hypothesis is submitted as valid.

description: Special solutions of the Hartree-Fock (HF) problem for Coulomb interacting electrons, being described by a simple model of the Cu-O planes in La2CuO4, are presented. One of the mean field states obtained, is able to predict some of the basic properties of this material, such as its insulator character and the antiferromagnetic order. The natural appearance of pseudogaps in some states of this compound is also indicated by another of the HF states obtained. These surprising results follow after eliminating spin and crystal symmetry restrictions which are usually imposed on the single particle HF orbitals, by means of employing a rotational invariant formulation of the HF scheme which was originally introduced by Dirac. Therefore, it is exemplified how, up to now being considered strong correlation effects, can be described by improving the HF solution of the physical systems. In other words, defining the correlation effects as such ones shown by the physical system and which are not predicted by the best HF (lowest energy) solution, allows to explain currently assumed as strong correlation properties, as simple mean field ones. The discussion also helps to clarify the role of the antiferromagnetism and pseudogaps in the physics of the HTSC materials and indicates a promising way to start conciliating the Mott and Slater pictures for the description of the transition metal oxides and other strongly correlated electron systems.

description: In this paper we want to apply the notion of product between ultrafilters to answer several questions which arise around the Connes' embedding problem. For instance, we will give a simplification and generalization of a theorem by Radulescu; we will prove that ultraproduct of hyperlinear groups is still hyperlinear and consequently the von Neumann algebra of the free group with uncountable many generators is embeddable into $R^ω$. This follows also from a general construction that allows, starting from an hyperlinear group, to find a family of hyperlinear groups. We will introduce the notion of hyperlinear pair and we will use it to give some other characterizations of hyperlinearity. We will prove also that the cross product of a hyperlinear group via a profinite action is embeddable into $R^ω$.

description: In this paper we determine the class of four-dimensional Lorentzian manifolds that can be completely characterized by the scalar polynomial curvature invariants constructed from the Riemann tensor and its covariant derivatives. We introduce the notion of an $\mathcal{I}$-non-degenerate spacetime metric, which implies that the spacetime metric is locally determined by its curvature invariants. By determining an appropriate set of projection operators from the Riemann tensor and its covariant derivatives, we are able to prove a number of results (both in the algebraically general and in algebraically special cases) of when a spacetime metric is $\mathcal{I}$-non-degenerate. This enables us to prove our main theorem that a spacetime metric is either $\mathcal{I}$-non-degenerate or a Kundt metric. Therefore, a metric that is not characterized by its curvature invariants must be of degenerate Kundt form. We then discuss the inverse question of what properties of the underlying spacetime can be determined from a given a set of scalar polynomial invariants, and some partial results are presented. We also discuss the notions of \emph{strong} and \emph{weak} non-degeneracy.

description: Abstract: Background: Low attendance and engagement in behavioural weight management trials are common. Mental health may play an important role, however previous research exploring this association is limited with inconsistent findings. We aimed to investigate whether mental health was associated with attendance and engagement in a trial of behavioural weight management programmes. Methods: This is a secondary data analysis of the Weight loss referrals for adults in primary care (WRAP) trial, which randomised 1267 adults with overweight or obesity to brief intervention, WW (formerly Weight Watchers) for 12-weeks, or WW for 52-weeks. We used regression analyses to assess the association of baseline mental health (depression and anxiety (by Hospital Anxiety and Depression Scale), quality of life (by EQ5D), satisfaction with life (by Satisfaction with Life Questionnaire)) with programme attendance and engagement in WW groups, and trial attendance in all randomised groups. Results: Every one unit of baseline depression score was associated with a 1% relative reduction in rate of WW session attendance in the first 12 weeks (Incidence rate ratio [IRR] 0.99; 95% CI 0.98, 0.999). Higher baseline anxiety was associated with 4% lower odds to report high engagement with WW digital tools (Odds ratio [OR] 0.96; 95% CI 0.94, 0.99). Every one unit of global quality of life was associated with 69% lower odds of reporting high engagement with the WW mobile app (OR 0.31; 95% CI 0.15, 0.64). Greater symptoms of depression and anxiety and lower satisfaction with life at baseline were consistently associated with lower odds of attending study visits at 3-, 12-, 24-, and 60-months. Conclusions: Participants were less likely to attend programme sessions, engage with resources, and attend study assessments when reporting poorer baseline mental health. Differences in attendance and engagement were small, however changes may still have a meaningful effect on programme effectiveness and trial completion. Future research should investigate strategies to maximise attendance and engagement in those reporting poorer mental health. Trial registration: The original trial (ISRCTN82857232) and five year follow up (ISRCTN64986150) were prospectively registered with Current Controlled Trials on 15/10/2012 and 01/02/2018.
Viable entanglement detection of unknown mixed states in low dimensions

description: We explore procedures to detect entanglement of unknown mixed states, which can be experimentally viable. The heart of the method is a hierarchy of simple feasibility problems, which provides sufficient conditions to entanglement. Our numerical investigations indicate that the entanglement is detected with a cost which is much lower than full state tomography. The procedure is applicable to both free and bound entanglement, and involves only single copy measurements.

description: We define lines of minima in the thick part of Outer space for the free group Fn with n>2 generators. We show that these lines of minima are contracting for the Lipschitz metric. Every fully irreducible outer automorphism of Fn defines such a line a minima. Now let G be a subgroup of the outer automorphism group of Fn which is not virtually abelian. We obtain as an immediate application that if G contains at least one fully irreducible element then for every p<1 the second bounded cohomology group with coefficients in lp(G) is infinite dimensional.

description: Abstract: Low-energy effective field theories containing a light scalar field are used extensively in cosmology, but often there is a tension between embedding such theories in a healthy UV completion and achieving a phenomenologically viable screening mechanism in the IR. Here, we identify the range of interaction couplings which allow for a smooth resummation of classical non-linearities (necessary for kinetic/Vainshtein-type screening), and compare this with the range allowed by unitarity, causality and locality in the underlying UV theory. The latter region is identified using positivity bounds on the 2→2 scattering amplitude, and in particular by considering scattering about a non-trivial background for the scalar we are able to place constraints on interactions at all orders in the field (beyond quartic order). We identify two classes of theories can both exhibit screening and satisfy existing positivity bounds, namely scalar-tensor theories of P(X) or quartic Horndeski type in which the leading interaction contains an odd power of X. Finally, for the quartic DBI Galileon (equivalent to a disformally coupled scalar in the Einstein frame), the analogous resummation can be performed near two-body systems and imposing positivity constraints introduces a non-perturbative ambiguity in the screened scalar profile. These results will guide future searches for UV complete models which exhibit screening of fifth forces in the IR.
Triply-resonant Optical Parametric Oscillator by Four-wave Mixing with Rubidium Vapor inside an Optical Cavity

description: We present an experimental demonstration of simultaneous above-threshold oscillations of the Stokes and anti-Stokes fields together with the single pumping beam with rubidium atoms inside an optical standing-wave cavity. The triple resonant conditions can be achieved easily by making use of the large dispersions due to two-photon transitions in the three-level atomic system. This work provides a way to achieve high efficient nonlinear frequency conversion and the generated bright Stokes and anti-Stokes cavity output beams are potential resource for applications in quantum information science.

Perception and representation : the visual cortex and landscape art, an investigation
Creators: name: Henskens, AS
Publisher: name: University Of Tasmania
Year: 2023

description: This project investigates artistic perception and representation of landscape as a means to determine how we construct a concept of what is real. It finds that the visual cortex perceives data in the form of light and that this data is translated by processes throughout the brain to arrive at a concept of reality. It posits these processes as being further influenced by the prevailing culture and technology. The conceptual base is grounded in a combination of present day neuro-physiological studies of the visual cortex, quantum physics and digital technology. Supporting theoretical material by physicists Paul Davies, Brian Green and various academic papers offer the view that what we experience as reality is determined by what filters through our sensory systems, and that the world is not what we take it to be as revealed by these sensory systems alone. The project takes the position that we tend to think of the world outside the self in terms of classical landscape; terms which are chiefly relevant to a different mindset and earlier stage of industrialised society. These ideas drive the project and are contextualised through the artworks of Georges Seurat, Bridget Riley, Geoff Parr, David Hockney, and Leigh Hobba, who explore self and the world in highly individual ways with a unique attitude to vision. Selected academic writings by Karl Popper, C.H.Waddington and StevenJohnson add strength to questioning orthodox realities and display certain parallels within the disciplines as to the value of apparent paradoxes, (see bibliography). Through a range of studio works the project pursued a visual exploration of landscape that reflects how we move through the world, scanning as we go, and building up a composite image from selected fragments. The imagery is based on the structure and action of the visual cortex reacting to natural forms. The processes used imitate viewing processes such as cellular edge-recognition, conveyed, for example, by laying down alternate sharp edges through spray-painting. The outcome is a series of works presented for exhibition on canvas, MDF board, paper and video, which encompass developments encountered in the course of the investigation. These artworks are presented in the thesis exhibition as perceptions of reality still in the process of resolution. The focus on the visual cortex as instrumental in apprehension presents a view of society as being inescapably animal in origin, evolutionary in its physical being, superficially overlaid by a drive to socialisation, and subject to modification.

description: We present an analysis of far-infrared dust emission from diffuse cirrus clouds. This study is based on serendipitous observations at 160 microns at high galactic latitude with the Multiband Imaging Photometer (MIPS) onboard the Spitzer Space Telescope by the Spitzer Infrared Nearby Galaxies Survey (SINGS). These observations are complemented with IRIS data at 100 and 60 microns and constitute one of the most sensitive and unbiased samples of far infrared observations at small scale of diffuse interstellar clouds. Outside regions dominated by the cosmic infrared background fluctuations, we observe a substantial scatter in the 160/100 colors from cirrus emission. We compared the 160/100 color variations to 60/100 colors in the same fields and find a trend of decreasing 60/100 with increasing 160/100. This trend can not be accounted for by current dust models by changing solely the interstellar radiation field. It requires a significant change of dust properties such as grain size distribution or emissivity or a mixing of clouds in different physical conditions along the line of sight. These variations are important as a potential confusing foreground for extragalactic studies.
