To what extent should the public be involved in health disinvestment decision making : a mixed methods investigation into the views of health professionals in the English NHS
Creators: name: Daniels, Thomas Andrew
Publisher: name: University of British Columbia
Year: 2016

description: Demand for health services is growing, but funding is often failing to keep pace. To ensure that budgets are balanced and that delivered services continue to be high quality, decision makers are having to set priorities, removing funding from some services- this is disinvestment. This thesis details research incorporating a literature review followed by a two stage empirical investigation into the way that disinvestment decisions are made and whether or not the public should be involved. The first stage is a Q-Methodology study, the second is in-depth interviews. The population for the study is NHS health professionals (including managers and clinicians). 55 participants took part in the Q-study, and of these, 20 took part in follow-up interviews. The study highlighted three distinct perspectives, all of which supported public involvement. One was unequivocal in its support, another highlighted some potential disadvantages to involving the public and the third suggested that the public should have the freedom to choose whether they became involved. The follow up interviews re-iterated participants’ support for involvement but suggested that the public should become involved earlier and to a greater extent in those disinvestment decisions which affected more patients and/or resulted in a tangible loss of services.

description: The apparent regularity of the motion of the giant planets of our solar system suggested for decades that said planets formed onto orbits similar to the current ones and that nothing dramatic ever happened during their lifetime. The discovery of extra-solar planets showed astonishingly that the orbital structure of our planetary system is not typical. Many giant extra-solar planets have orbits with semi major axes of $\sim 1$ AU, and some have even smaller orbital radii, sometimes with orbital periods of just a few days. Moreover, most extra-solar planets have large eccentricities, up to values that only comets have in our solar system. Why such a big diversity between our solar system and the extra-solar systems, as well as among the extra-solar systems themselves? This chapter aims to give a partial answer to this fundamental question....

description: The construction of needlet-type wavelets on sections of the spin line bundles over the sphere has been recently addressed in Geller and Marinucci (2008), and Geller et al. (2008,2009). Here we focus on an alternative proposal for needlets on this spin line bundle, in which needlet coefficients arise from the usual, rather than the spin, spherical harmonics, as in the previous constructions. We label this system mixed needlets and investigate in full their properties, including localization, the exact tight frame characterization, reconstruction formula, decomposition of functional spaces, and asymptotic uncorrelation in the stochastic case. We outline astrophysical applications.

description: Photonic integrated circuits hold great potential for realizing quantum technology. Efficient single-photon detectors are an essential constituent of any such quantum photonic implementation. In this regard waveguide-integrated superconducting nanowire single-photon detectors are an ideal match for achieving advanced photon counting capabilities in photonic integrated circuits. However, currently considered material systems do not readily satisfy the demands of next generation nanophotonic quantum technology platforms with integrated single-photon detectors, in terms of refractive-index contrast, band gap, optical nonlinearity, thermo-optic stability and fast single-photon counting with high signal-to-noise ratio. Here we show that such comprehensive functionality can be realized by integrating niobium titanium nitride superconducting nanowire single-photon detectors with tantalum pentoxide waveguides. We demonstrate state-of-the-art detector performance in this novel material system, including devices showing 75% on-chip detection efficiency at tens of dark counts per second, detector decay times below 1 ns and sub-30 ps timing accuracy for telecommunication wavelengths photons at 1550 nm. Notably, we realize saturation of the internal detection efficiency over a previously unattained bias current range for waveguide-integrated niobium titanium nitride superconducting nanowire single-photon detectors. Our work enables the full set of high-performance single-photon detection capabilities on the emerging tantalum pentoxide-on-insulator platform for future applications in integrated quantum photonics.

description: What fascinates us about animal behavior is its richness and complexity, but understanding behavior and its neural basis requires a simpler description. Traditionally, simplification has been imposed by training animals to engage in a limited set of behaviors, by hand scoring behaviors into discrete classes, or by limiting the sensory experience of the organism. An alternative is to ask whether we can search through the dynamics of natural behaviors to find explicit evidence that these behaviors are simpler than they might have been. We review two mathematical approaches to simplification, dimensionality reduction and the maximum entropy method, and we draw on examples from different levels of biological organization, from the crawling behavior of C. elegans to the control of smooth pursuit eye movements in primates, and from the coding of natural scenes by networks of neurons in the retina to the rules of English spelling. In each case, we argue that the explicit search for simplicity uncovers new and unexpected features of the biological system, and that the evidence for simplification gives us a language with which to phrase new questions for the next generation of experiments. The fact that similar mathematical structures succeed in taming the complexity of very different biological systems hints that there is something more general to be discovered.

description: We present the results of the Nobeyama Radio Observatory (NRO) M33 All Disk (30'x30' or 7.3 kpc x 7.3 kpc) Survey of Giant Molecular Clouds (NRO MAGiC) based on 12CO (1-0) observations using the NRO 45-m telescope. The spatial resolution of the resultant map is 19".3, corresponding to 81 pc, which is sufficient to identify each Giant Molecular Cloud (GMC) in the disk. We found clumpy structures with a typical spatial scale of ~100 pc, corresponding to GMCs, and no diffuse, smoothly distributed component of molecular gas at this sensitivity. Closer inspection of the CO and HI maps suggests that not every CO emission is associated with local HI peaks, particularly in the inner portion of the disk (r < 2 kpc), although most of CO emission is located at the local HI peaks in the outer radii. We found that most uncovered GMCs are accompanied by massive star-forming regions, although the star formation rates (SFRs) vary widely from cloud to cloud. The azimuthally averaged H{\sc i} gas surface density exhibits a flat radial distribution. However, the CO radial distribution shows a significant enhancement within the central 1-2 kpc region, which is very similar to that of the SFR. We obtained a map of the molecular fraction, f_mol = Sigma_H_2/(Sigma_HI+Sigma_H_2, at a 100-pc resolution. This is the first f_mol map covering an entire galaxy with a GMC-scale resolution. We find that f_mol tends to be high near the center. The correlation between f_mol and gas surface density shows two distinct sequences. The presence of two correlation sequences can be explained by differences in metallicity, i.e., higher (~ 2-fold) metallicity in the central region (r< 1.5 kpc) than in the outer parts. Alternatively, differences in scale height can also account for the two sequences, i.e., increased scale height toward the outer disk.

A series of aryl bromides and terminal olefin were applied to this catalytic system and the corresponding coupling products were produced in high yields. The reusability tests demonstrated that the catalyst system could be recycled for six runs with only a slightly decreased activity.

Application of metabolomics to identify metabolite patterns showing the importance of dietary carbohydrate source in neonatal rats
Creators: name: Chetty, Vinodha
Publisher: name: University of British Columbia
Year: 2016

description: Lactose is a glucose and galactose disaccharide and is found exclusively in mammalian milk. The evolution of lactose as a unique component of human milk (with 50% galactose) and its metabolic advantage in infants is poorly understood. There is also a limited understanding of the potential implications of clinical nutrition support using lactose-free nutrition, such as dextrose (glucose) as the sole carbohydrate source in intravenous nutrition and glucose-corn syrup solids (CSS) (100% glucose) in formula for infants. The liver takes up 90% of galactose. In contrast, the liver clears only 30% of glucose. Glucose stimulates release of insulin from the pancreas whereas galactose does not. The goal of my thesis was to use ‘metabolomics’, in a neonatal rat model of gastrostomy feeding, to differentiate metabolic effects in rat pups fed milk formula complete in protein, fat, minerals and vitamins, but with either lactose or CSS as the carbohydrate source. I hypothesize that galactose and specific metabolites of galactose metabolism will be differentiated between lactose-fed and CSS-fed rat pups by target compound analysis; and targeted metabolomics will highlight differences in metabolite patterns in hepatic metabolism from lactose or CSS feeding. Liver, plasma and urine samples were collected at 10 and 14 days after birth. Significant differences in galactose and galactonate levels were observed in the liver at day 10 and 14, with no differences glucose. Metabolites that were different between the groups were: D-Ribose, pyrimidine, glycine and malate in rat pups at day 10 and leucine and isoleucine at day 10 and 14, which were significantly higher in the lactose-fed group. The data obtained show that early dietary lactose has definitive effects on hepatic metabolites that can be mapped to pathways of carbohydrate, protein, and fat metabolism and are different to non-lactose carbohydrate feeding. My findings suggest that utilization of galactose, as a consistent source of glucose could prove beneficial for supply to glucose-dependent organs such as the rapidly developing infant brain. Advancing the use of metabolomics to enhance understanding of the impact of diet will provide an opportunity to improve health outcome for infants.

description: We consider on-center and off-center observers in an inhomogeneous, spherically symmetric, isocurvature (flat) concentration of dark energy with typical size of a few Gpc. Such a concentration could be produced e.g. by a recently formed global monopole with core size that approaches the Hubble scale. In this case we would have what may be called `topological quintessence' in analogy with the well-known topological inflation. We show that the minimum comoving radius r_{0min} of such a dark energy inhomogeneity that is consistent with the Union2 Type Ia supernovae (SnIa) data at the 3σlevel is r_{0min}\simeq 1.8 Gpc. As expected, the best-fit fractional dark energy density at the center, Ω_X,in, approaches the corresponding LCDM value Ω_X,in =0.73 for large enough values of the inhomogeneity radius r_0 (r_0 > 4Gpc). Using the Union2 data, we show that the maximum allowed shift r_{obs-max} of the observer from the center of the inhomogeneity is about 0.7 r_0 which respects the Copernican principle. The model naturally predicts the existence of a preferred axis and alignment of the low CMB multipoles. However, the constraints on r_{obs-max} coming from the magnitude of the CMB dipole remain a severe challenge to the Copernican principle and lead to r_{obs-max}< 110 Mpc even for an inhomogeneity radius as large as r_0=7 Gpc.

description: The costs which occur during the operation and maintenance (O&M) phase of the offshore wind farms greatly influence the levelized costs of electricity (LCOE). The maintenance of floating offshore wind systems come with additional constrains and challenges due to the more complex accessibility and the likely further distance from shore of the assets. It is thus of high interest to investigate if the use of monitoring technologies can contribute to a reduction in overall operating costs.
 This study analyses the effect of structural health monitoring technologies on the O&M cost and availabilities figure of a reference wind farm. A Ramboll’s in-house O&M model is extended to be capable of considering the maintenance actions in response to alarms and floating offshore wind O&M strategies. The focus is on floating specific components, for which the most promising monitoring technologies are presented and ranked according to a Failure Mode Effect Analysis (FMEA). Following, an investigation is conducted to determine the most critical hotspots.
 The presence of the selected monitoring system is then modelled into the O&M cost model by updating the maintenance logistics and scheduling of actions from a baseline scenario. By comparing the results of the baseline scenario to the one applying the condition-based maintenance strategy, the benefits of the deployment of the monitoring systems are evident. The operational expenditures (OPEX) per MW and year are shown to be reduced of 15% of the baseline ones. This seems to be additionally associated to an increase of the wind farm availability figures, resulting in a further potential increase in the revenue.

description: We investigate solitons and nonlinear Bloch waves in Bose-Einstein condensates trapped in optical lattices. By introducing specially designed localized profiles of the spatial modulation of the attractive nonlinearity, we construct an infinite number of exact soliton solutions in terms of the Mathieu and elliptic functions, with the chemical potential belonging to the semi-infinite bandgap of the optical-lattice-induced spectrum. Starting from the exact solutions, we employ the relaxation method to construct generic families of soliton solutions in a numerical form. The stability of the solitons is investigated through the computation of the eigenvalues for small perturbations, and also by direct simulations. Finally, we demonstrate a virtually exact (in the numerical sense) composition relation between nonlinear Bloch waves and solitons.

description: This within-between subject design experiment will investigate how reading stoic passages can be used to mitigate negative emotions in response to a hypothetical romantic rejection scenario. The study will have participants randomly allocated to two conditions: a stoic reading condition and a control condition. During the stoic reading condition, participants will be instructed to read a passage on stoic philosophy and then summarize their thoughts. In the control condition, participants will read a non-related passage and summarize their thoughts. After completing the reading task, participants will be presented with a hypothetical scenario that describes them being romantically rejected by their partner. Participants will be asked to rate their emotions (such as sadness, anger, fear) using a visual analogue mood scale. The study will measure changes in emotional response between the two conditions to examine the effectiveness of stoic reading in mitigating negative emotions. This study will also explore the extent to which stoic ideology can be increased using stoic reading.

Flux and profile measurements of an atomic beam using laser cooled atoms
Creators: name: Prescott, Thomas
Publisher: name: University of British Columbia
Year: 2016

description: The population dynamics of a Magneto-Optical Trap (MOT) make it a potential candidate for flux measurements of an atomic beam. This is achieved by determining the collisional cross section of the trapped atom and the beam particle which would result in ejection of a trapped atom. Due to the properties of a MOT it is possible to make spatial and time-of-flight profiles of the beam using this technique. The work of this thesis explores the collisional cross sections and flux profiles of several gaseous beams with a MOT of ⁸⁵Rb or ⁸⁷Rb. Each of the beams, generated through supersonic expansion, produced a loss cross section on the order of the combined van-der-Waals radii of the two particles. The flux and time-of-flight information of the beam was verified with a Residual Gas Analyser (RGA) and high beam rep rate pressure measurements. The MOT was characterized through a combination of fluorescence detection for population and a catalysis process for the trap's depth. A custom built translation mechanism for the MOT's optics and Helmholtz coils was constructed to perform the profiling measurements.

description: We present new multiband photometry for the Galactic globular cluster IC 4499 extending well past the main sequence turn-off in the U, B, V, R, I, and DDO51 bands. This photometry is used to determine that IC4499 has an age of 12 pm 1 Gyr and a cluster reddening of E(B-V) = 0.22 pm 0.02. Hence, IC 4499 is coeval with the majority of Galactic GCs, in contrast to suggestions of a younger age. The density profile of the cluster is observed to not flatten out to at least r~800 arcsec, implying that either the tidal radius of this cluster is larger than previously estimated, or that IC 4499 is surrounded by a halo. Unlike the situation in some other, more massive, globular clusters, no anomalous color spreads in the UV are detected among the red giant branch stars. The small uncertainties in our photometry should allow the detection of such signatures apparently associated with variations of light elements within the cluster, suggesting that IC 4499 consists of a single stellar population.

Heat shock protein 27 inhibits the Hippo tumor suppressor pathway by facilitating MST1 proteasomal degradation
Creators: name: Vahid, Sepideh
Publisher: name: University of British Columbia
Year: 2017

description: Heat shock protein 27 (Hsp27) is a molecular chaperone highly and ubiquitously expressed in aggressive cancers where it controls a variety of pro-tumorigenic signaling pathways. Using gene expression profiling in prostate cancer cells with loss of Hsp27 function, we identified for the first time that Hsp27 regulates target genes in signaling pathways dependent on YAP and TAZ. Suppression of these transcriptional co-activators occurs via their phosphorylation and cytoplasmic retention by the Hippo tumor suppressor pathway. Mechanistic studies revealed that Hsp27 expression is associated with reduced YAP phosphorylation and enhanced transcription of YAP/TAZ target genes. Examination of the core components of the Hippo kinase cascade revealed that Hsp27 facilitates the proteasomal degradation of the core Hippo kinase, MST1, leading to reduced phosphorylation/activity of other main kinases responsible for YAP phosphorylation/inactivation, LATS1 and MOB1. Importantly, our data from cell lines was supported by data from human tumors; clinically, high expression of Hsp27 correlates with increased expression of YAP target genes in prostate cancer as well as reduced phosphorylation of YAP in lung and invasive breast cancer clinical samples. Together, our data reveal a novel mechanism by which Hsp27 regulates the Hippo tumor suppressor pathway, providing further rationale to target Hsp27 in multiple cancers.

description: Both Uranus and Neptune are thought to have strong zonal winds with velocities of several hundred meters per second. These wind velocities, however, assume solid-body rotation periods based on Voyager 2 measurements of periodic variations in the planets' radio signals and of fits to the planets' magnetic fields; 17.24h and 16.11h for Uranus and Neptune, respectively. The realization that the radio period of Saturn does not represent the planet's deep interior rotation and the complexity of the magnetic fields of Uranus and Neptune raise the possibility that the Voyager 2 radio and magnetic periods might not represent the deep interior rotation periods of the ice giants. Moreover, if there is deep differential rotation within Uranus and Neptune no single solid-body rotation period could characterize the bulk rotation of the planets. We use wind and shape data to investigate the rotation of Uranus and Neptune. The shapes (flattening) of the ice giants are not measured, but only inferred from atmospheric wind speeds and radio occultation measurements at a single latitude. The inferred oblateness values of Uranus and Neptune do not correspond to bodies rotating with the Voyager rotation periods. Minimization of wind velocities or dynamic heights of the 1 bar isosurfaces, constrained by the single occultation radii and gravitational coefficients of the planets, leads to solid-body rotation periods of ~16.58h for Uranus and ~17.46h for Neptune. Uranus might be rotating faster and Neptune slower than Voyager rotation speeds. We derive shapes for the planets based on these rotation rates. Wind velocities with respect to these rotation periods are essentially identical on Uranus and Neptune and wind speeds are slower than previously thought. Alternatively, if we interpret wind measurements in terms of differential rotation on cylinders there are essentially no residual atmospheric winds.

description: Interferometric millimeter observations of the cosmic microwave background and clusters of galaxies with arcmin resolutions require antenna arrays with short spacings. Having all antennas co-mounted on a single steerable platform sets limits to the overall weight. A 25 kg lightweight novel carbon-fiber design for a 1.2 m diameter Cassegrain antenna is presented. The finite element analysis predicts excellent structural behavior under gravity, wind and thermal load. The primary and secondary mirror surfaces are aluminum coated with a thin TiO$_2$ top layer for protection. A low beam sidelobe level is achieved with a Gaussian feed illumination pattern with edge taper, designed based on feedhorn antenna simulations and verified in a far field beam pattern measurement. A shielding baffle reduces inter-antenna coupling to below $\sim$ -135 dB. The overall antenna efficiency, including a series of efficiency factors, is estimated to be around 60%, with major losses coming from the feed spillover and secondary blocking. With this new antenna, a detection rate of about 50 clusters per year is anticipated in a 13-element array operation.

description: We develop a mechanism for the controlled conversion of ballistic to diffusive motion and vice versa. This process takes place at the interfaces of domains with different time-dependent forces in lattices of laterally oscillating barrier potentials. As a consequence long-time transient oscillations of the particle density are formed which can be converted to permanent density waves by an appropriate tuning of the driving forces. The proposed mechanism opens the perspective of an engineering of the nonequilibrium dynamics of particles in inhomogeneously driven lattices.

Small, dark, with some yellow spots on the pterothorax. Head much broader than long, with almost straight occipital margin (Fig. 65), Antennae as illustrated (Fig. 66); segment 6 the longest, dark basally; apical segment spindle-shaped with pointed tip. Hinge of labium reaching second coxae. Labium as in Figs. 67-68. Hind margin of pronotum laterally somewhat protru· ding, and spinous. Legs moderately long, femora with two dark rings. Wing sheaths reaching to end of abdominal segment 5. Abdomen with dorsal hooks on segments 3-9 and with long lateral spines on segments 8 and 9 (Fig. 69). Anal pyramid as in Fig. 70. Measurements. Total length (excl. lateral spi· nes) 9.5; maximum width of head across compound eyes 3.0; hind femur 3.0; hind tibia 3.6. Remarks. The larva was found between leaf lit. ter in the pool described under Acanthagrion apicale (see above) Here, adult males as well as an ovipositing female were observed. The larva when disturbed feigns death. The unique specimen found was reared to emergence, but died during transformation. Therefore it can be associated with Fylgia kirby only by supposition. Ho. wever, small size and peculiar features practically exclude any other genus.

description: James Philip Elliott, one of the towering figures of nuclear physics of the second half of the twentieth century, died on the 21st of October 2008. Obituaries appeared in the British press but relatively little attention was paid by the international scientific community to Elliott's contributions. Given their importance, in particular for theoretical nuclear physics, it seems appropriate to reflect here, two years after his death, on the scientific legacy left by Phil Elliott.

description: Despite having a great potential, the current costs of floating offshore wind prevent it from being deployed massively at a global scale. This situation is driving many research works to improve the floating wind feasibility and speed up its implantation. One of the newest fields of innovation is the digitalisation of assets, which applied to the floating wind farms can lead to a reduction of their LCOE. The reasons include the complexity of the floating wind projects, the large investments required, the size of the components, the environments where the farms are installed and the inherent accessibility and workability issues.
 Other technologies have been digitalised before the floating wind industry, therefore there is already experience in the industry and general guidelines can be extracted. A key stage where the digitalisation can lead to an LCOE reduction is the maintenance, and the first step is determining the typical failures that occur in a floating wind farm. As the floating wind technology is still advancing on its first steps, there is a noticeable lack of failure rates of floating wind components and some of them have been extracted from the bottom-fixed technology or the oil and gas platforms. An inverse relationship between failure rates and repair times is observed and fatigue and corrosion are identified two critical failure causes.

description: We present a study of signatures of on-going star formation in a sample of protostellar objects with enhanced 4.5 μm emission ('green' sources) near the Galactic center. To understand how star formation in the Galactic center region compares to that of the Galactic disk, we used the Expanded Very Large Array to observe radiatively excited Class II 6.7 GHz CH3OH masers and collisionally excited Class I 44 GHz CH3OH masers, both tracers of high-mass star formation, toward a sample of 34 Galactic center and foreground 'green' sources. We find that 33\pm15% of Galactic center sources are coincident with 6.7 GHz masers, and that 44\pm17% of foreground sources are coincident with 6.7 GHz masers. For 44 GHz masers, we find correlation rates of 27\pm13% and 25\pm13% for Galactic center green sources and foreground green sources, espectively. Based on these CH3OH maser detection rates, as well as correlations of green sources with other tracers of star formation, such as 24 μm emission and infrared dark clouds (IRDCs), we find no significant difference between the green sources in the Galactic center and those foreground to it. This suggests that once the star formation process has begun, the environmental differences between the Galactic center region and the Galactic disk have little effect on its observational signatures. We do find, however, some evidence that may support a recent episode of star formation in the Galactic center region.
