description: In the standard scenario for galaxy evolution young star-forming galaxies transform into red bulge-dominated spheroids, where star formation has been quenched. To explain such a transformation, a strong negative feedback generated by accretion onto a super-massive black hole is often invoked. The depletion of gas resulting from quasar-driven outflows should eventually stop star-formation in the host galaxy and lead the black hole to "suicide" for starvation. Direct observational evidence for a major quasar feedback onto the host galaxy is still missing, since outflows previously observed in quasars are generally associated with the ionized component of the gas, which only accounts for a minor fraction of the total gas content, and typically occurring in the central regions. We used the IRAM PdB Interferometer to observe CO(1-0) in Mrk 231, the closest QSO known. Thanks to the wide band we detect broad wings of the CO line, with velocities up to 750 km/s and spatially resolved on the kpc scale. Such broad CO wings trace a giant molecular outflow of about 700 MSun/yr, far larger than the ongoing star-formation rate (~200 MSun/yr) observed in the host galaxy. This wind will totally expel the cold gas reservoir in Mrk 231 in about 1e7 yrs, therefore halting the star-formation activity on the same timescale. The inferred kinetic energy in the molecular outflow is ~1.2e44 erg/s, corresponding to a few percent of the AGN bolometric luminosity, very close to the fraction expected by models ascribing quasar feedback to highly supersonic shocks generated by radiatively accelerated nuclear winds. The direct observational evidence for quasar feedback reported here provides solid support to the scenarios ascribing the observed properties of local massive galaxies to quasar-induced large scale winds.

description: Electrons in solids are characterized by the energy bands, which indicate that electrons are considered to be "elementary particles" with specific effective masses and g-factors reflecting features of each solid. There are cases where these particles obey dispersion relationship similar to those of Dirac electrons. Examples include graphite and bismuth both of which are known for many years, together with graphene, a single layer of graphite, recently addressed intensively after its realization. Another recent example is a molecular solid, alpha-ET2I3, which is described by an equation similar to Weyl equation with massless Dirac cones but the coordinate axis is tilted because of the location of cones at off-symmetry points. Orbital susceptibility of such Dirac electrons in graphite and bismuth has been known to have striking features not present in ordinary band electrons but resulting from the inter-band matrix elements of magnetic field. Results of theoretical studies on not only orbital susceptibility but also Hall effect of such Dirac electrons in molecular solids with tilting are introduced in this paper.

Spatio-temporal correlations of galaxy star formation histories

description: Our understanding of galaxy evolution is often hindered by the complexity of the processes that drive it. Star formation offers a powerful tool for tracing galaxy growth, and star formation history (SFH) reconstruction techniques make this even more powerful by allowing us to probe backwards in cosmic time. Combining this with spatial information between and within galaxies, we can test correlations within populations, between pairs, and across regions of a galaxy. When populations, pairs, and regions are studied jointly, correlations between SFHs can provide insights into the processes of hierarchical structure formation, large scale environmental influences, local baryon cycling, and additional drivers of galaxy evolution. Here we present work that revealed synchronized star formation in the SFHs of dwarf galaxies in the Local Volume at lookback times between 3 and 6 Gyr. Further investigation of the Local Volume found conformity for star formation rates and quenched fractions of galaxies when comparing the properties of pairs, using the SFHs to conduct the first search for conformity back in cosmic time. Finally, we show results from a search for correlations within individual galaxies by reconstructing the SFHs from the spectral energy distributions of spatially resolved regions in UVCANDELS galaxies.

description: Exact chiral symmetry at finite lattice spacing would preclude the axial anomaly. In order to describe a continuum quantum field theory of Dirac fermions, lattice actions with purported exact chiral symmetry must break the flavor-singlet axial symmetry. We demonstrate that this is indeed the case by using a minimally doubled fermion action. For simplicity we consider the Abelian axial anomaly in two dimensions. At finite lattice spacing and with gauge interactions, the axial anomaly arises from non-conservation of the flavor-singlet current. Similar non-conservation also leads to the axial anomaly in the case of the naive lattice action. For minimally doubled actions, however, fine tuning of the action and axial current is necessary to arrive at the anomaly. Conservation of the flavor non-singlet vector current additionally requires the current to be fine tuned. Finally we determine that the chiral projection of a minimally doubled fermion action can be used to arrive at a lattice theory with an undoubled Dirac fermion possessing the correct anomaly in the continuum limit.

We extract the scattering matrix from the wave-packet in the kink background at very late times and compare it with the result from static potential scattering in the small amplitude approximation. We vary the size of the initial wave-packet to identify non-linear effects as, for example, the replacement of the center of the kink.

Impact of British Columbia's reduction in generic drug prices on statin adherence
Creators: name: Mushashi, Fidela
Publisher: name: University of British Columbia
Year: 2017

description: Background: The burden of cost of prescription medications for chronic conditions is substantial. Many patients do not take their medication as prescribed due to cost. In 2010 the government of British Columbia introduced policy changes that reduced generic prices over a period of four years. I studied the impact of five generic price reductions policy on adherence to statin medications. Methods: Using data from the British Columbia Ministry of Health through Population Data BC, I analyzed prescription claims of 433,945 residents who were on statins from 2008 to 2014. I measured medication adherence using proportion of days covered (PDC) with brand name statin users as my control group. Interrupted time series analysis was used to compare longitudinal trends before and after policy changes. Results: Residents on brand name statins on average had 89.9% (95% CI 0.8924 to 0.9059) proportion of days covered with medication prior to policy interventions. Pre-existing level of adherence to generic statins was 0.89 percentage points (-0.0007 to 0.0184) higher relative to the control. There was a sustained significant decrease of 0.05 percentage points (-0.0009 to -0.00001) per month in trend of brand name use (p=0.0473). Adherence to generics dropped by 0.02 percentage points (-0.0009 to 0.0005) relative to the control over the 24 months preceding policy interventions. After first policy intervention, adherence to brand name statins increased immediately by 1.1 percentage points (-0.0032 to 0.0245) while generics utilization decreased by 0.71 percentage points (-0.0267 to 0.0125) relative to the control. Trend in control decreased by 0.03 percentage points (-0.0026 to 0.0021). After the first policy, there was a rise in trend of generics adherence of 0.27 percentage points (-0.0006-0.0061) per month relative to the control. Further price reductions resulted in moderate improvement in adherence to generic statins. Conclusion: Findings indicate that reductions in generic drug prices in BC yielded a modest improvement in pharmaceutical claims for statins. In the future, health policy makers may want to consider fewer but larger drug price reduction interventions for a more effective impact on medication adherence.
The mating/parenting trade-off : evidence and implications
Creators: name: Beall, Alec T.
Publisher: name: University of British Columbia
Year: 2017

description: According to the biological principles of life history theory, there is a fundamental trade-off between mating effort and parenting effort. The five studies reported here (N = 3,439) tested two conceptually distinct ways in which that trade-off might manifest at a psychological level of analysis. Studies 1 and 2 focus on developmental processes and individual differences in the chronic activation of the mate acquisition and parenting motivational systems. Studies 3, 4, and 5 focus on temporary activation and inhibition of the mate acquisition and parenting motivational systems. The primary results of Study 1 (n = 305) suggest that men who express a greater desire to engage in short-term mating behavior have a less intense nurturant parental response to infants; Study 2 (n = 2252) revealed similar inverse relations, this time among both men and women (as well as parents and nonparents). Study 2 additionally noted a positive correlation between short-term mating orientation and chronic protective parental tendencies. Results from Study 3 (n = 92) indicate that the temporary arousal of a parental care-giving motivational state consequently inhibits self-reported inclinations toward short-term mating; this effect was only found in women. Results from Studies 4 (n = 308) and 5 (n = 482) suggest that temporary arousal of a mate acquisition motivational state consequently inhibits self-reported tender emotional responses towards infants. No consistent sex differences were noted in this latter result. Results of Study 5 additionally suggest that the temporary arousal of a disease- and predator-avoidance motivational states consequently inhibit self-reported nurturant emotional responses towards infants as well. No consistent sex differences were noted in these effects. Taken together, the present research yields results consistent with hypothesized psychological manifestations of the mating/parenting trade-off. But the present research also yields additional results that pose a challenge to these seemingly straightforward hypotheses, suggesting that a more nuanced approach must be taken to understand how the mating/parenting trade-off might manifest psychologically.

description: We elaborate further on the static supersymmetric AdS_4 black holes found in arXiv:0911.4926, investigating thoroughly the BPS constraints for spherical symmetry in N = 2 gauged supergravity in the presence of Fayet-Iliopoulos terms. We find Killing spinors that preserve two of the original eight supercharges and investigate the conditions for genuine black holes free of naked singularities. The existence of a horizon is intimately related with the requirement that the scalars are not constant, but given in terms of harmonic functions in analogy to the attractor flow in ungauged supergravity. The black hole charges depend on the choice of the electromagnetic gauging, with only magnetic charges for purely electric gaugings. Finally we show how these black holes can be embedded in N = 8 supergravity and thus in M-theory.

description: A series of polyurethane-based nanocomposites with different contents of N-GQD nanoparticles were prepared via solution casting and in-situ polymerization methods. Hydrogen bonding content of carbonyl groups (HBI(C=O)) of samples were studied by FTIR. Crystalline structure and thermal behavior of samples were investigated by XRD and DSC. Incorporating of N-GQDs in PU matrix can affect the HBI(C=O) and degree of crystallinity. The FESEM images illustrate N-GQD nanoparticles have uniform dispersion in samples obtained by in-situ polymerization. Shape memory behavior was examined at room temperature and 60°C. Both PU nanocomposites preparation methods and nanoparticles content have significant effect on thermo-mechanical properties.

description: We determine the galaxy infrared (IR) luminosity function (LF) as a function of the environment in a supercluster at z=0.23, using optical, near-IR, and mid- to far-IR photometry, as well as redshifts from optical spectroscopy. We identify 467 supercluster members in a sample of 24-micron-selected galaxies, on the basis of their spectroscopic (153) and photometric (314) redshifts. IR luminosities, stellar masses and star formation rates (SFRs) are determined for supercluster members via spectral energy distribution fitting and the Kennicutt relation. Galaxies with active galactic nuclei are excluded from the sample. We determine the IR LF of the whole supercluster as well as the IR LFs of three different regions in the supercluster: the cluster core, a large-scale filament, and the cluster outskirts (excluding the filament). The IR LF shows an environmental dependence which is not simply related to the local galaxy density. The filament, an intermediate-density region in the A1763 supercluster, contains the highest fraction of IR-emitting galaxies at all levels of IR luminosities. As expected, the core contains the lowest fraction of IR-emitting galaxies and almost no Luminous IR Galaxies (LIRGs). The relation between galaxy specific SFRs and stellar masses does not depend on the environment, and it indicates that most supercluster LIRGs (in particular those in the filament) are rather massive galaxies with relatively low specific SFRs. A comparison with previous IR LF determinations from the literature confirms that the mass-normalized total SFR in clusters increases with redshift, but more rapidly than previously suggested for redshifts <0.4. We interpret our findings within a possible scenario for the evolution of galaxies in and around clusters [Abridged].

description: We study an anisotropic inflation model with a gauge kinetic function for a non-abelian gauge field. We find that, in contrast to abelian models, the anisotropy can be either a prolate or an oblate type, which could lead to a different prediction from abelian models for the statistical anisotropy in the power spectrum of cosmological fluctuations. During a reheating phase, we find chaotic behaviour of the non-abelian gauge field which is caused by the nonlinear self-coupling of the gauge field. We compute a Lyapunov exponent of the chaos which turns out to be uncorrelated with the anisotropy.

Variable analytical methods reveal the presence of the polymer strands after the ligation. The grafting density of the hybrid materials was compared to a conventional ligation technique involving an acidic pre-functionalization of the SWCNTs.

description: The reliable detection of single quantum particles has revolutionized the field of quantum optics and quantum information processing. For several years, researchers have aspired to extend such detection possibilities to larger scale strongly correlated quantum systems, in order to record in-situ images of a quantum fluid in which each underlying quantum particle is detected. Here we report on fluorescence imaging of strongly interacting bosonic Mott insulators in an optical lattice with single-atom and single-site resolution. From our images, we fully reconstruct the atom distribution on the lattice and identify individual excitations with high fidelity. A comparison of the radial density and variance distributions with theory provides a precise in-situ temperature and entropy measurement from single images. We observe Mott-insulating plateaus with near zero entropy and clearly resolve the high entropy rings separating them although their width is of the order of only a single lattice site. Furthermore, we show how a Mott insulator melts for increasing temperatures due to a proliferation of local defects. Our experiments open a new avenue for the manipulation and analysis of strongly interacting quantum gases on a lattice, as well as for quantum information processing with ultracold atoms. Using the high spatial resolution, it is now possible to directly address individual lattice sites. One could, e.g., introduce local perturbations or access regions of high entropy, a crucial requirement for the implementation of novel cooling schemes for atoms on a lattice.

description: We report a process to fabricate carbon nanotubes (CNT) by chemical vapor deposition at predetermined location. This process was enabled by patterning catalyst nanoparticles directly on silicon substrates with nanometer-scale precision using Dip Pen Nanolithography(R) (DPN(R)). A multi-pen writing method was employed to increase the patterning rate. The development of new molecular inks for the deposition of the precursor catalyst resulted in a high yield of isolated carbon nanotubes, ideal for subsequent device fabrication. Here, we demonstrate the advantages of the new method for producing high quality isolated CNT in scalable array geometries.

description: The complex state of rolling of the tire-cavity-wheel-suspension system is experimentally investigated. The influence of the contact of the tire with a rough road surface and the tire's vibrational excitation are analysed in experiments. The findings gained are used to build up an improved rolling noise model. Beyond the structural dynamics of the tire, the model includes the tire-cavity medium plus the wheel and simulates the interaction with the modeled suspension.

description: The directed transport of Brownian particles requires a system with an asymmetry and with non-equilibrium noise. We here investigate numerically alternative ways of fulfilling these requirements for a two-state Brownian motor, realised with Brownian particles alternating between two phase-shifted, symmetric potentials. We show that, besides the previously known spatio-temporal asymmetry based on unequal transfer rates between the potentials, inequalities in the potential depths, the frictions, or the equilibrium temperatures of the two potentials also generate the required asymmetry. We also show that the effects of the thermal noise and the noise of the transfer's randomness depend on the way the asymmetry is induced.
Electricity use analysis of existing and planned university buildings, and opportunities for life cycle costing
Creators: name: Glaser, Leonard
Publisher: name: University of British Columbia

description: Increasing environmental awareness has initiated a change in building design and efficiency in order to reduce the large amount of energy associated with this industry. Life cycle cost (LCC) analysis is a decision-making tool to evaluate the economic long-term benefits of different design options compared to the building’s basic design. LCC analysis can motivate decision-makers to reallocate building budgets towards higher initial capital costs if the long-term operational savings balance higher upfront expenses. However, LCC needs well-calibrated predictive modeling for such savings to be realized. ‘Bottom up’ Energy modeling software has been used to evaluate savings associated with different building designs. Although these models require a large amount of building specific information, their predictions are often far off from the actual energy use. An alternative proposed in this thesis is to use ‘top down’ models that predict energy consumption using aggregate building characteristics such as size, age, type and occupancy. We have developed a ‘top-down’ model for electricity use in buildings based on daily electricity consumption data of 48 research buildings at the University of British Columbia (UBC). The model is a set of linear regressions analyzed with MATLAB. Our model requires only a few simple, aggregate inputs in order to make electricity use predictions. These compare favorably to the more complex LEED energy tested models for ten UBC research buildings. Thus, the ‘top down’ models are an additional, useful tool for energy planning and design. The effort to collect data for such models is also small compared to the ‘bottom-up’ alternative.
Propionic acid degradation by syntrophic bacteria during anaerobic biowaste treatment
Creators: name: Felchner-Zwirello, Monika
Publisher: name: Karlsruhe
Year: 2013

description: Propionic acid is an important intermediate produced during anaerobic degradation of biowaste and a precursor of a large amount of methane. Its accumulation during biomethanation is however a common problem resulting in stagnation phases in biogas production. During this study, the deeper insight into the process of propionic acid degradation was intended by using modern analytical chemistry, standard microbiological approach and molecular biology for describing and explaining the problem.
Accurate calibration of the Raman system for the Karlsruhe Tritium Neutrino Experiment

description: The KATRIN experiment aims to measure the neutrino mass with a sensitivity of m=0.2 eV/c² (90% C.L.). One parameter, the isotopic composition of the tritium gas source, is measured inline by Raman spectroscopy. The required measurement trueness of the composition is <10%. Thus, accurate calibration of the Raman system is required. This is successfully obtained by two independent calibration methods: a gas sampling technique and an approach via theoretical intensities plus spectral sensitivity.

description: We study a stochastic model of protein dynamics that explicitly includes delay in the degradation. We rigorously derive the master equation for the processes and solve it exactly. We show that the equations for the mean values obtained differ from others intuitively proposed and that oscillatory behavior is not possible in this system. We discuss the calculation of correlation functions in stochastic systems with delay, stressing the differences with Markovian processes. The exact results allow to clarify the interplay between stochasticity and delay.
