description: We have performed experimental and theoretical studies of the structural stability of YAsO4 and YCrO4 at high pressures. X-ray diffraction experiments together with ab initio total-energy and lattice-dynamics calculations have allowed us to completely characterize a pressure-induced structural phase transition from the zircon to the scheelite structure in both compounds. Furthermore, total-energy calculations have been performed to check the relative stabilities of different candidate structures at different pressures and allow us to propose for YAsO4 the zircon \rightarrow scheelite \rightarrow SrUO4-type sequence of structures. In this sequence, sixfold arsenic coordination is attained for the SrUO4-type structure above 32 GPa. The whole sequence of transitions is discussed in comparison with YVO4, YPO4, YNbO4, YMoO4, and YTaO4. Also a comparative discussion of lattice-dynamics properties is presented. The band-gap for YAsO4 and YCrO4 and band structure for YAsO4 are also reported. Finally, the room-temperature equation of state of different compounds is also obtained.

description: A perturbation approach based on the first-order mean spherical approximation (FMSA) is proposed. It consists in adopting a hard-sphere plus short-range attractive Yukawa fluid as the novel reference system, over which the perturbative solution of the Ornstein-Zernike equation is performed. A choice of the optimal range of the reference attraction is discussed. The results are compared against conventional FMSA/HS theory and Monte-Carlo simulation data for compressibility factor and vapor-liquid phase diagrams of the medium-ranged Yukawa fluid. Proposed theory keeps the same level of simplicity and transparency, as the conventional FMSA/HS approach does, but shows to be more accurate.

description: Aims and Objectives: To explore the impact of nursing home leadership and staffing characteristics on staff job satisfaction, health and intention to leave. Background: The number of older people has outpaced growth in the nursing home workforce worldwide. Identifying predictors with the potential to positively impact staff job satisfaction, health and intentions to leave are important. Leadership of the nursing home manager can be one such predictor. Design: Cross-sectional design. Methods: A sample of 2985 direct care staff in 190 nursing homes in 43 randomly selected municipalities in Sweden completed surveys on leadership, job satisfaction, self-rated health and intention to leave (response rate 52%). Descriptive statistics and Generalised Estimating Equations were conducted. The STROBE reporting checklist was applied. Results: Nursing home managers' leadership was positively related to job satisfaction, self-rated health and low intention to leave. Lower staff educational levels were related to poorer health and lower job satisfaction. Conclusions: Nursing home leadership plays a significant role in the job satisfaction, self-reported health and intention to leave of direct care staff. Low education levels among staff seem to negatively influence staff health and job satisfaction, suggesting that educational initiatives for less-educated staff could be beneficial for improving staff health and job satisfaction. Relevance to clinical practice: Managers seeking to improve staff job satisfaction can consider how they support, coach and provide feedback. Recognising staff achievement at work can contribute to high job satisfaction. One important implication for managers is to offer continuing education to staff with lower or no education, given the large amount of uneducated direct care workers in aged care and the impact this may have on staff job satisfaction and health. No patient or public contribution: No patient or public contribution was required to outcome measures in this study. Direct care staff and managers contributed with data.

description: We study Maxwell's equations on a 4-manifold where the electromagnetic medium is modelled by an antisymmetric (2, 2)-tensor kappa with real coefficients. In this setting the Fresnel surface is a fourth order polynomial surface in each cotangent space that acts as a generalisation of the light cone determined by a Lorentz metric; the Fresnel surface parameterises electromagnetic wave-speeds as a function of direction. The contribution of this paper is the complete pointwise description of all electromagnetic medium tensors that satisfy the following conditions: (i) kappa is invertible, (ii) kappa is skewon-free, (iii) kappa is birefringent, that is, the Fresnel surface of kappa is the union of two distinct light cones. We show that there are only three classes of mediums with these properties. Moreover, we give explicit expressions in local coordinates for each class.

description: White food-grade sugar is highly processed involving multi-steps that remove most of the natural minerals and phytochemicals that improve health and increase sweetness. The over usage of sugars in daily diet is a well-publicized global challenge. Food companies are increasingly required to reduce sugar content for our health and wellbeing but a less refined “real raw” sugar that could reduce added sugars to food is still unavailable. This project is established to introduce spray drying as a technique to develop a less refined, healthier sweetener that could reduce the quantity of added sugar to foods. The significant sugar reduction provides the industry with a real raw sugar product and sugar reduction solution to the global challenge of sugar over-usage.

How experiments (past, present and future) at Jefferson Lab probe colourless nuclei to map out these internal colour degrees of freedom is presented. When combined with theoretical calculations, these will paint a picture of how the confinement of quarks and gluons, and the structure of the QCD vacuum, determine the properties of all (light) strongly interacting states.

Primary cementing of a highly deviated oil well
Creators: name: Carrasco-Teja, Mariana
Publisher: name: University of British Columbia
Year: 2010

description: In this thesis we study laminar displacement flows of one ﬂuid by another in a horizontal annulus. The study comes from the primary cementing of highly deviated oil and gas wells. Highly deviated wells are those in which part of the well bore is nearly horizontal. Primary cementing is a critical process in the construction of a well. The objective is to provide zonal isolation, i.e., a hydraulic seal between the well and the surrounding rock. This is essential to protect the environment and increase the productivity of the well. Therefore, an understanding of the process is indispensable. We model primary cementing displacement flows using a Hele-Shaw approach, and provide simple scientific tools to improve the design of cementing jobs. The contribution of the thesis comes in three parts. Firstly, we analyse the displacement of one viscoplastic fluid by another in a near-horizontal eccentric annulus with a fixed inner pipe. We present examples that illustrate the differences between vertical and horizontal displacements. We then derive a 1D lubrication model which gives analytical conditions that predict when the flow will stratify, according to the fluid properties and the annulus geometry. Secondly, we derive a 2D displacement model for Newtonian fluids which includes rotation and reciprocation of the inner cylinder. This is a common practice in the industry and not well understood. Using an asymptotic approach, we find steady-state traveling wave solutions for nearly- flat interfaces. Then we use numerical simulations to understand the flow dynamics for more elongated interfaces. In particular, we show that casing rotation can lead to local instabilities and mixing, which can shorten the length of the interface. Finally, we generalise this moving casing model to viscoplastic ﬂuids. Using a lubrication- type model we explore the effects of casing motion, again deriving conditions for there to be steady solutions.
Constructing all entanglement witnesses from density matrices

Subjects: subject: Quantum Physics (quant-ph)

description: We demonstrate a general procedure to construct entanglement witnesses for any entangled state. This procedure is based on the trace inequality and a general form of entanglement witnesses, which is in the form $W=ρ-c_ρ I$, where $ρ$ is a density matrix, $c_ρ$ is a non-negative number related to $ρ$, and $I$ is the identity matrix. The general form of entanglement witnesses is deduced from Choi-Jamiołkowski isomorphism, that can be reinterpreted as that all quantum states can be obtained by a maximally quantum entangled state pass through certain completely positive maps. Furthermore, we provide the necessary and sufficient condition of the entanglement witness $W=ρ-c_ρI$ in operation, as well as in theory.

description: Plasmonic nanoparticles are important building blocks in modern nanotechnology due to their merits such as excellent size/shape control, unique optical and catalytic properties. However, it is the surface ligands which usually play an essential role in determining their colloidal stability and functional versatility, among which, smart polymers are extremely intriguing because it allows plasmonic nanoparticles to respond to external stimuli. In this thesis, new phenomena and engineering designs are demonstrated based on smart polymers modified individual plasmonic building blocks and their assemblies and these findings will pave the way towards smart plasmonics with better designs and novel properties.
title: Biogeochemical Cycling in a High-Altitude Andean Lake: Insights into Potential Microbial Metabolisms During the Noachian and Hesperian Periods on Mars
Creators: name: Tatton, Ben
Publisher: name: The Open University
Year: 2024

description: This PhD aimed to identify metabolic processes potentially prevalent in martian paleolakes to inform the selection and identification of biosignatures in present and future missions. To achieve this aim, I studied a high-altitude lake (HAL) with geochemical and climatological characteristics similar to those predicted for Yellowknife Bay, Gale Crater, Mars, during the Noachian-Hesperian transition.
During the Noachian-Hesperian transition, the martian climate has been suggested as semi-arid to arid, cold, with high ultraviolet radiation (UV) levels. To identify the most appropriate analogue, ecoregions where HALs had been described had daily UV radiation flux, annual precipitation, diurnal temperature fluctuation, and mean daily temperature analysed. Using machine-learning approaches, the geochemical composition of fluids from HALs was compared to thermochemically modelled martian fluids. 
The Central Andean dry Puna was identified as having a climate representative of Noachian-Hesperian Mars, appropriate geological context due to the active volcanism within the Central Andes, and HALs with water chemistry similar to thermochemical models. As such, Laguna de Antofagasta (LDA), a high-altitude Andean Lake, was selected to be investigated. 
Geochemical analysis indicated that LDA was oligotrophic, with sediment comprised of weathered minerals from igneous sources. Bacteria were the dominant domain, representing >99% of total prokaryotes identified, with members of the Pseudomonadota and Bacteroidota being the dominant phyla. Canonical correspondence analysis (CCA) indicated that S, total C, and DO significantly impact microbial community composition across sampling sites. 
Metagenomic analyses identified sulphur-oxidation as the dominant metabolism within the LDA benthic environment, with members of the genera Thiobacillus, Sulfuricaulis, and Thiocapsa accounting for 92.59 % of total reads sequenced from sedimentary samples. Nitrate was also identified as an important electron acceptor, with genes associated with denitrification and dissimilatory nitrate reduction to ammonium (DNRA) consistently detected. 
The dominance of this environment by S-oxidisers highlights sulphur-oxidation as a Mars-relevant metabolism. Results also suggest that sulphide may influence nitrogenous compounds in martian paleolake environments. Understanding connectivity between biogeochemical cycles under Mars-relevant conditions can inform current and future sampling efforts and subsequent biosignature detection.

description: Majorana representation of quantum states by a constellation of n 'stars' (points on the sphere) can be used to describe any pure state of a simple system of dimension n+1 or a permutation symmetric pure state of a composite system consisting of n qubits. We analyze the variance of the distribution of the stars, which can serve as a measure of the degree of non-coherence for simple systems, or an entanglement measure for composed systems. Dynamics of the Majorana points induced by a unitary dynamics of the pure state is investigated.

description: Perovskite solar cells (PSCs) reached power conversion efficiencies comparable to the silicon alternatives, currently dominating the photovoltaic market. Researchers are now seeking to address other factors that are inhibiting the rate of commercialisation of perovskite technologies such as the scalability of the manufacturing process and stability. This thesis presents an investigation into benefits of implementing a quasi-interdigitated back-contact (QIBC) architecture in perovskite photovoltaic devices. In situ experiments are performed during the deposition of the photoactive material and during post-treatment experiments. Furthermore, an antireflective coating for QIBC PSCs is proposed, which simultaneously acts as a passivation and encapsulation layer.

These nontrivial resonances are determined directly by the trapped atomic population on the definite lower level of the Λ-system and may be used in atomic frequency standards, sensitive magnetometers and in ultrahigh resolution laser spectroscopy of atoms and molecules.

description: Halide perovskites have emerged as one of the most interesting materials for optoelectronic applications due to their favorable properties, such as defect-tolerance and long charge carrier lifetimes, which are attributed to their dynamic softness. However, this softness has led to apparent disagreements between the local instantaneous and global average structures of these materials. In this work, we assess the local tilt angles of octahedra in the perovskite structure through large-scale molecular dynamics simulations using machine learned potentials based on density functional theory. We compare structural properties given by different density functionals, namely PBE, PBEsol, SCAN, and vdW-DF-cx, and establish trends across a family of CsMX3 with M=Sn or Pb and X=Cl, Br or I perovskites. Notably, we demonstrate a strong short-range ordering that persists even in the cubic phase of halide perovskites. This ordering is reminiscent of the tetragonal phase and bridges the disordered local structure and the global cubic arrangement. Our results provide a deeper understanding of the structural properties of halide perovskites and their local distortions, which is crucial for further understanding their optoelectronic properties.

The polarization of the solar MgII h and k lines
Creators: name: Belluzzi, Luca

Publisher: name: arXiv
Year: 2012
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: Although the h and k lines of MgII are expected to be of great interest for probing the upper solar chromosphere, relatively little is known about their polarization properties which encode the information on the magnetic field. Here we report the first results of an investigation whose main goal is to understand the physical mechanisms that control the scattering polarization across these resonance lines and to achieve a realistic radiative transfer modeling in the presence of arbitrary magnetic fields. We show that the joint action of partial frequency redistribution (PRD) and quantum interference between the two excited J-levels produces a complex fractional linear polarization (Q/I) pattern with large polarization amplitudes in the blue and red wings, and a negative feature in the spectral region between the two lines. Another remarkable peculiarity of the Q/I profile is a conspicuous antisymmetric signal around the center of the h line, which cannot be obtained unless both PRD and J-state interference effects are taken into account. In the core of the k line, PRD effects alone produce a triplet peak structure in the Q/I profile, whose modeling can be achieved also via the two-level atom approximation. In addition to the Hanle effect in the core of the k line, we emphasize also the diagnostic potential of the circular polarization produced by the Zeeman effect in the h and k lines, as well as in other MgII lines located in their wings.

Liouville-Arnold integrability of the pentagram map on closed polygons

Publisher: name: arXiv
Year: 2011
Subjects: subject: Dynamical Systems (math.DS)

description: The pentagram map is a discrete dynamical system defined on the moduli space of polygons in the projective plane. This map has recently attracted a considerable interest, mostly because its connection to a number of different domains, such as: classical projective geometry, algebraic combinatorics, moduli spaces, cluster algebras and integrable systems. Integrability of the pentagram map was conjectured by R. Schwartz and later proved by V. Ovsienko, R. Schwartz and S. Tabachnikov for a larger space of twisted polygons. In this paper, we prove the initial conjecture that the pentagram map is completely integrable on the moduli space of closed polygons. In the case of convex polygons in the real projective plane, this result implies the existence of a toric foliation on the moduli space. The leaves of the foliation carry affine structure and the dynamics of the pentagram map is quasi-periodic. Our proof is based on an invariant Poisson structure on the space of twisted polygons. We prove that the Hamiltonian vector fields corresponding to the monodoromy invariants preserve the space of closed polygons and define an invariant affine structure on the level surfaces of the monodromy invariants.

Structural effects of the built environment on vehicle greenhouse gas emissions : evidence from Vancouver, Canada
Creators: name: Devlin, Andrew John
Publisher: name: University of British Columbia
Year: 2010

description: This thesis summarizes efforts to estimate fundamental relationships among built environment characteristics, activity patterns and vehicle use in order to assess their relative influences on vehicle GHG emission generation in Metro Vancouver, Canada. Activity-based structural equation models were specified in a cross-sectional study design using local travel survey data and highly detailed urban form data. Structural equation analysis permitted explicit modeling of the indirect effects between built environment variables and vehicle emissions as mediated through activity patterns and vehicle use. Modeling travel at the activity-tour level allowed for a deeper understanding of the relative contributions of local and regional built environment variables in explaining tour complexity, vehicle use and emissions. Controlling for pertinent socio-economic and demographic variables, standardized parameter coefficients show the built environment to be a significant predictor of vehicle-related GHG emissions across all models, although the strength and magnitude of these effects vary by activity tour type. The local built environment is a stronger predictor of vehicle use and related emissions for non-work/school tours, while regional accessibility measures yielded larger effects on the carbon-intensity of work and school tours. Vehicle accessibility yielded significantly large effects on vehicle use and emissions across all models, suggesting that policy directions beyond promoting more compact, walkable and regionally connected development to curb emissions are required. Additional strategies may include those that address vehicle use in a more direct manner, including higher taxation, insurance or parking fees. Future research would benefit by incorporating travel and residential preferences to control for self-selection, assessing the affect of the work and school built environment on activity patterns and undertaking a more holistic assessment of the links between the built environment and total household emissions and energy use (including building, transportation, etc).

description: Despite the developments in digital technologies, people with a print disability such as blindness or low vision have limited access to reading material in accessible formats. This “global book famine” affects their opportunities for learning, participating in the social and economic life of society, and leading a balanced life. With limited research in this area, and poor understanding and collaboration among alternative content producers and publishers, a potential opportunity exists to transform the creation and production of accessible content in Australia. This exploratory study of Australian book publishers seeks to better understand the issues affecting the production of accessible content. While the results from this sample cannot be generalised to the whole publishing industry in Australia, this study offers valuable insights into the level of engagement of the publishing industry in the implementation of accessibility standards, and identifies the key drivers and challenges that publishers encounter.

description: The depletion of abiotic resources is a critical issue for present and future generations. Resource depletion is governed by several factors including resource costs and elasticity of demand, which are dynamic. In this thesis, a dynamic resource depletion impact assessment methodology is proposed that takes into account the rate of depletion and the alternatives that are available to a country for substitution. The methodology is evaluated for two regional case studies considering natural gas as the depleting resource. The first case study evaluates the importance of natural gas to New Zealand, a developed economy. The second case study examines the significance of natural gas to India, a developing economy with growing energy needs in a manner that has relatively low environmental burdens.

Ballistic regime of weak localization where the backscattering occurs from few impurities is studied with account for anisotropic momentum scattering of holes. The transition from weak localization to anti-localization is demonstrated for long dephasing times. For stronger dephasing the conductivity correction is negative at all hole densities due to non-monotonous dependence of the spin relaxation time on the hole wavevector. The anomalous temperature dependent correction to the conductivity is calculated. We show that the temperature dependence of the conductivity is non-monotonous at moderate hole densities.

description: Instytucja „rzeczy wyłączonych z obrotu” (res extra commercium), wywodząca się z rzymskiego podziału rzeczy, nie jest instytucją wprost uregulowaną przez ustawodawcę w polskim porządku prawnym. Mimo iż jest to narzędzie prawne przywoływane przez przedstawicieli doktryny, orzecznictwa czy też, w pewnych przypadkach, prawodawcę, wydaje się, że do dnia dzisiejszego nie wypracowano ogólnej definicji rozumienia pojęcia tzw. „rzeczy wyłączonych z obrotu”. Na podstawie wybranych przepisów prawnych, orzeczeń oraz poglądów wyrażonych w doktrynie autor niniejszego opracowania analizuje zarówno zasadność uznawania konkretnych przykładów jako „rzeczy wyłączone z obrotu”, jak i dopuszczalność wyróżniania niniejszej instytucji na gruncie obecnego porządku prawnego.

description: The shallow decay phase of the early X-ray afterglow in gamma-ray bursts discovered by {\it Swift} is a widely discussed topic. As the spectral index does not change at the transferring of the shallow decay phase to a normal phase, it implies this transferring should be a dynamical change rather than a spectral evolution. We suggest both the shallow decay phase and the normal phase are from the external shock in a wind environment, while the transferring time is the deceleration time. We apply this model to GRBs 050319 and 081008, and find them can be well explained by choosing a proper set of parameters.

description: This work studied the particle-fluid flows in packed and fluidized beds by multiscale simulations. The focus was on the relationship between microscopic particle-particle/particle-fluid interactions and macroscopic behaviors of the systems. Particle scale simulations using the coupled computational fluid dynamics and discrete element method (CFD-DEM) were conducted for understanding the settling, defluidization and gas-fluidization of particles. The discrete particle simulation was also linked to continuum properties through averaging method of granular materials. Pore scale network model was developed for simulating fluid flows through packed beds; its coupling with DEM was also realized for simulation of particle-fluid flows at an equivalent scale.
Apollonian packings as physical fractals

description: The Apollonian packings (APs) are fractals that result from a space-filling procedure with spheres. We discuss the finite size effects for finite intervals $s\in[s_\mathrm{min},s_\mathrm{max}]$ between the largest and the smallest sizes of the filling spheres. We derive a simple analytical generalization of the scale-free laws, which allows a quantitative study of such \textit{physical fractals}. To test our result, a new efficient space-filling algorithm has been developed which generates random APs of spheres with a finite range of diameters: the correct asymptotic limit $s_\mathrm{min}/s_\mathrm{max}\rightarrow 0$ and the known APs' fractal dimensions are recovered and an excellent agreement with the generalized analytic laws is proved within the overall ranges of sizes.

description: We consider systems of ODEs with the right hand side being Laurent polynomials in several non-commutative unknowns. In particular, these unknowns could be matrices of arbitrary size. An important example of such a system was proposed by M. Kontsevich. We prove the integrability of the Kontsevich system by finding a Lax pair, corresponding first integrals and commuting flows. We also provide a pre-Hamiltonian operator which maps gradients of integrals for the Kontsevich system to symmetries.

Making Sense of Serotonin Through Spike Frequency Adaptation

description: What does serotonin do? Just as the diffuse axonal arbours of midbrain serotonin neurons touch nearly every corner of the forebrain, so too is this ancient neuromodulator involved in nearly every aspect of learning and behaviour. The role of serotonin in reward processing has received increasing attention in recent years, but there is little agreement about how the perplexing responses of serotonin neurons to emotionally salient stimuli should be interpreted, and essentially nothing is known about how they arise. Here I approach these two aspects of serotonergic function in reverse order. In the first part of this thesis, I construct an experimentally-constrained spiking neural network model of the dorsal raphe nucleus (DRN), the main source of forebrain serotonergic input, and characterize its signal processing features. I show that potent spike-frequency adaptation deeply shapes DRN output while other aspects of its physiology are relatively less important. Overall, this part of my work suggests that in vivo serotonergic activity patterns arise from a temporal-derivative-like computation. But the temporal derivative of what? In the second part, I consider the possibility that the DRN is driven by an input that represents cumulative future reward, a quantity called state value in reinforcement learning theory. The resulting model reproduces established tuning features of serotonin neurons, including phasic activation by reward predicting cues and punishments, reward-specific surprise tuning, and tonic modulation by reward and punishment context. Because these features are the basis of many and varied existing serotonergic theories, these results show that my theory, which I call value prediction, provides a unifying perspective on serotonergic function. Finally, in an empirical test of the theory, I re-analyze data from an in vivo trace conditioning experiment and find that value prediction accounts for the firing rates of serotonin neurons to a precision ≪0.1 Hz, outperforming previous models by a large margin. Here I establish serotonin as a new neural substrate of prediction and reward, a significant step towards understanding the role of serotonin signalling in the brain.
