description: Tomography of redshifted 21 cm transition from neutral Hydrogen using Fourier synthesis telescopes is a promising tool to study the Epoch of Reionization (EoR). Limiting the confusion from Galactic and Extragalactic foregrounds is critical to the success of these telescopes. Instrumental response or the Point Spread Function (PSF) of such telescopes is inherently 3 dimensional with frequency mapping to the Line of Sight (LOS) distance. EoR signals will necessarily have to be detected in data where continuum confusion persists; therefore, it is important that the PSF has acceptable frequency structure so that the residual foreground does not confuse the EoR signature. This paper aims to understand the 3 dimensional PSF and foreground contamination in the same framework. We develop a formalism to estimate the foreground contamination along frequency, or equivalently LOS dimension, and establish a relationship between foreground contamination in the image plane and visibility weights on the Fourier plane. We identify two dominant sources of LOS foreground contamination-'PSF contamination' and 'gridding contamination'. We show that 'PSF contamination' is localized in LOS wavenumber space, beyond which there potentially exists an 'EoR window' with negligible foreground contamination where we may focus our efforts to detect EoR. 'PSF contamination' in this window may be substantially reduced by judicious choice of a frequency window function. Gridding and imaging algorithms create additional 'gridding contamination' and we propose a new imaging algorithm using the Chirp Z Transform (CZT) that significantly reduces this contamination. Finally, we demonstrate the analytical relationships and the merit of the new imaging algorithm for the case of imaging with the Murchison Widefield Array (MWA).

description: Reproducibility is a key aspect of science, and both, publishers and funders increasingly ask for the raw data and details of the data processing to be available. However, still most papers lack the details necessary to fully reproduce
 the data analysis. This can in part be attributed to a lack of appropriate software tools helping the researchers to document both, data acquisition and analysis automatically and with the required details. We present a Python framework for the fully reproducible Analysis of Spectroscopic Data (AspecD) requiring no programming skills of the users thanks to a unique user interface in form of recipes formatted as YAML file. Based on this framework, a number of packages has been developed, most notably for the analysis of cw-EPR and tr-EPR data. Furthermore, we show a simple yet powerful file format for recording metadata during data acquisition that is both, human-writable and machine-readable. Together, these software tools tremendously enhance the reproducibility of our data analysis and hence the overall quality of the reported science.

description: We present a global study of low mass, young stellar object (YSO) surface densities in nearby (< 500 pc) star forming regions based on a comprehensive collection of Spitzer Space Telescope surveys. We show that the distribution of YSO surface densities in the solar neighbourhood is a smooth distribution, being adequately described by a lognormal function from a few to 10^3 YSOs per pc^2, with a peak at 22 stars/pc^2 and a dispersion of 0.85. We do not find evidence for multiple discrete modes of star-formation (e.g. clustered and distributed). Comparing the observed surface density distribution to previously reported surface density threshold definitions of clusters, we find that the fraction of stars in clusters is crucially dependent on the adopted definitions, ranging from 40 to 90%. However, we find that only a low fraction (< 26%) of stars are formed in dense environments where their formation/evolution (along with their circumstellar disks and/or planets) may be affected by the close proximity of their low-mass neighbours.

description: The infrared structure of SU(2) Yang-Mills theory is studied by means of lattice gauge simulations using a new constrained cooling technique. This method reduces the action while all Polyakov lines on the lattice remain unchanged. In contrast to unconstrained cooling, quark confinement is still intact. A study of the Hessian of the Yang-Mills action shows that low action (semi-) classical configurations can be achieved, with a characteristic splitting between collective modes and higher momentum modes. Besides confinement, the semiclassical configurations also support the topological susceptibility and generate spontaneous breakdown of chiral symmetry.We show that they possess a cluster structure of locally mainly (anti-) selfdual objects. By contrast to an instanton or a meron medium, the topological charge of individual clusters is smoothly distributed.

description: We investigate the formation of both clustered and distributed populations of young stars in a single molecular cloud. We present a numerical simulation of a 10,000 solar mass elongated, turbulent, molecular cloud and the formation of over 2500 stars. The stars form both in stellar clusters and in a distributed mode which is determined by the local gravitational binding of the cloud. A density gradient along the major axis of the cloud produces bound regions that form stellar clusters and unbound regions that form a more distributed population. The initial mass function also depends on the local gravitational binding of the cloud with bound regions forming full IMFs whereas in the unbound, distributed regions the stellar masses cluster around the local Jeans mass and lack both the high-mass and the low-mass stars. The overall efficiency of star formation is ~ 15 % in the cloud when the calculation is terminated, but varies from less than 1 % in the the regions of distributed star formation to ~ 40 % in regions containing large stellar clusters. Considering that large scale surveys are likely to catch clouds at all evolutionary stages, estimates of the (time-averaged) star formation efficiency for the giant molecular cloud reported here is only ~ 4 %. This would lead to the erroneous conclusion of 'slow' star formation when in fact it is occurring on a dynamical timescale.

An evaluation of Canadians values and attitudes towards expensive drugs for rare diseases
Creators: name: Rizzardo, Shirin
Publisher: name: University of British Columbia
Year: 2014

description: Background: Expensive drugs for rare diseases pose a great challenge for decision-makers involved in determining their funding status due to their extremely high treatment costs, the small patient populations, the uncertainty of evidence for treatment effectiveness and a moral obligation to provide treatment where there is no alternative. The decision to fund a medication is traditionally and primarily guided by two factors: the drug’s cost and its effectiveness. This efficiency-based method is useful in guiding funding decisions for common medications, however is insufficient for rare diseases as they are unlikely to meet current cost-effectiveness thresholds, and moreover does not consider values associated with rarity including disease severity, unmet need and equity. Decision-makers are using values to determine rare disease funding status; however, it is unknown whether these decisions reflect societal priorities. Should society value rarity, this may provide decision-makers with the justification for the funding of expensive drugs which serve a disproportionately small population. Objectives: Identify the public values on health technologies, and the criteria society feels are most important for guiding priority-setting for health technology assessment and drug-reimbursement; Determine the relative importance of rarity; Determine whether society values rarity and accepts the opportunity costs associated with funding high-cost medications. Methods: We conducted an online survey of 2211 Canadians where multiple methodologies including simple ranking with an analytic hierarchy process, measures of attitudes towards equity statements, and trade-off questions were employed. Results: The values most important to Canadians for drug-reimbursement prioritization are drug safety, effect on quality and quantity of life, and certainty of efficacy. Factors related to rare diseases such as severity and equity are important factors to Canadians; however, rarity alone was of relatively low importance for the priority-setting of orphan drug treatment. Although society was not found to be willing to accept the opportunity cost for funding a rare disease if it is at the cost of a common condition, they prefer funding of a rare disease over a non-health benefit. Equity and equal access to drug treatments are important factors to Canadians, though rarity alone is not justification for prioritizing a drug treatment for funding.
Classical Skyrmions -- Static Solutions and Dynamics

description: Skyrmions with a realistic value of the pion mass parameter are expected to be quite compact structures, but beyond baryon number B=8 only a few examples are known. The largest of these is the cubically symmetric B=32 Skyrmion which is a truncated piece of the Skyrme crystal. Here it is proposed that many more such Skyrmions could be found, without any restriction on the baryon number, as pieces of the Skyrme crystal. Particular attention is given to the possibility of reducing B by 1 by chopping a corner off a cubic crystal chunk. Nuclei are modelled by Skyrmions with quantised spin and isospin. Here it is argued that these quantised states can be approximated by classically spinning Skyrmions. The orientations of the spinning Skyrmions corresponding to polarised protons, neutrons and deuterons are identified. Nuclear collisions and the nuclear spin-orbit force are discussed in terms of classically spinning Skyrmions. Going beyond the rigid collective motions of Skyrmions, there are spatially modulated collective motions, which are oscillatory in time. They are argued to describe not just vibrational excitations of nuclei, but also giant resonance states. A speculative proposal for identifying quarks inside Skyrmions is briefly discussed.

description: Amphinemura palmeni Koponen 1916 The NHM contains no ethanol-preserved or slidemounted specimens labelled as such, nor do Lillehammer’s publications bear evidence that he studied specimens of A. palmeni. The online data portals do not contain any observations either. Very few findings of this species have ever been reported. The absence of specimens and observations of this red-listed taxon is due to the uncertainty of its taxonomic status. Koponen (1917) described Amphinemura palmeni from the Kola Peninsula in northwest Russia. Brinck (1949:19) considered the name to be a synonym of A. standfussi (Ris 1902), ‚considering the description and the type material'. Then Tobias (1973) described A. norvegica from northern Norway. Meinander (1975) reports that Tobias and Baumann later checked the type of A. palmeni and found out that both A. norvegica and the Nearctic A. linda (Ricker 1952) were conspecific with A. palmeni. Illies’s catalogue (1966:185) reproduces Brinck’s opinion, while his chapter in Limnofauna Europaea (Illies 1978) later follows Meinander. Lillehammer’s (1988) identification key and handbook lists A. palmeni as a valid species and A. norvegica Tobias 1973 as its junior synonym. I am currently re-examining the taxonomic status of this species. Preliminary analyses of mitochondrial sequences from P. cf. palmeni from Finnmark and Troms provinces in Norway and bordering Finland (northern Lapland province) show that two distinct clades of standfussi -like stoneflies occur in northern Scandinavia. Further research should establish whether these clades can be considered as easterly forms of A. standfussi, and whether the different clades interbreed.

HURRICANE EFFECTS ON TROPICAL STREAM MEIOFAUNA: AN EXPERIMENTAL SIMULATION OF MAJOR ABIOTIC IMPACTS

description: Hurricanes affect ecosystem in diverse ways, thus changing its structure the dynamics. Streams are greatly affected by hurricanes due to sedimentation, organic matter entrance and sunlight (trough canopy openness).  This could in turn affect the biodiversity of streams. Meiofaunal organisms might undergo changes after a hurricane in a stream since they are highly dependent on sediment composition, organic matter and streamflow. To determine which environmental variable is stronger structuring the meiofauna after a hurricane we performed a controlled factorial design experiment with 2 levels (pre and post hurricane) and 4 replicates. The factors were sediment composition, organic matter and sunlight. The first sample (10 mL) of meiofauna was collected 1 week after the initial set-up, the next samples were collected 2 days after the addition of the post-hurricane level. After 1 week a final sample was collected. All samples were fixed in 2% Rose Bengal. A nMDS and ANOVA was performed to detect significant differences. The nMDS before the addition of the post-hurricane treatments revealed that meiofaunal community was not different among treatments. However, the nMDS after the addition of the post hurricane levels showed that communities started to show differences among treatments. An ANOVA revealed that richness and abundance in sediment and organic matter treatments where significantly different. We conclude that a hurricane can change the meiofaunal community by changes in the environment such as sediment from landslides and the depletion of organic matter entrance.

description: The ATLAS Muon Spectrometer is designed to measure the momentum of muons with a resolution of dp/p = 3% and 10% at 100 GeV and 1 TeV momentum respectively. For this task, the spectrometer employs 355,000 Monitored Drift Tubes (MDTs) arrayed in 1200 Chambers. Calibration (RT) functions convert drift time measurements into tube-centered impact parameters for track segment reconstruction. RT functions depend on MDT environmental parameters and so must be appropriately calibrated for local chamber conditions. We report on the creation and application of a gas monitor system based calibration program for muon track reconstruction in the LHC startup phase.

description: It is commonly believed that most of the stars born in associations decaying with characteristic velocities of stars ~10 km/s. For dwarf galaxies the decay can lead to ejection of stars from the galaxy. The effect is studied for spheroidal and disk dwarf galaxies, and is shown to have substantional observational consequences for disk galaxies with escape velocities up to 20 km/s, or dynamical masses up to 10^8 M_sol. The ejection of stars can (i) reduce the abundances of the products of Type Ia supernovae and, to a lesser degree, Type II supernovae, in disk stars, (ii) chemically enrich the galactic halo and intergalactic medium, (iii) lead to the loss of 50% of the stellar mass in galaxies with masses ~10^7 M_sol and the loss of all stars in system with masses 10^5 M_sol, (iv) increase the mass-to-luminosity ratio of the galaxies.

description: The scaling properties of elliptic flow of hadrons produced in ultrarelativistic heavy-ion collisions are investigated at low transverse momenta, $p_T\lsim 2$\,GeV. Utilizing empirical parameterizations of a thermalized fireball with collective-flow fields, Resonance Recombination Model (RRM) is employed to describe hadronization via quark coalescence at the hadronization transition. We reconfirm that RRM converts equilibrium quark distribution functions into equilibrated hadron spectra including the effects of space-momentum correlations on elliptic flow. This provides the basis for a controlled extraction of quark distributions of the bulk matter at hadronization from spectra of multi-strange hadrons which are believed to decouple close to the critical temperature. The resulting elliptic flow from empirical fits at RHIC exhibits transverse kinetic-energy and valence-quark scaling. Utilizing the well-established concept of sequential freeze-out we find that the scaling at low momenta can be extended to bulk hadrons ($π$, $K$, $p$) at thermal freeze-out, and thus result in an overall description compatible with both equilibrium hydrodynamics and quark recombination.

description: The KamLAND and Borexino experiments have detected electron antineutrinos produced in the decay chains of natural thorium and uranium (Th and U geoneutrinos). We analyze the energy spectra of current geoneutrino data in combination with solar and long-baseline reactor neutrino data, with marginalized three-neutrino oscillation parameters. We consider the case with unconstrained Th and U event rates in KamLAND and Borexino, as well as cases with fewer degrees of freedom, as obtained by successively assuming for both experiments a common Th/U ratio, a common scaling of Th+U event rates, and a chondritic Th/U value. In combination, KamLAND and Borexino can reject the null hypothesis (no geoneutrino signal) at 5 sigma. Interesting bounds or indications emerge on the Th+U geoneutrino rates and on the Th/U ratio, in broad agreement with typical Earth model expectations. Conversely, the results disfavor the hypothesis of a georeactor in the Earth's core, if its power exceeds a few TW. The interplay of KamLAND and Borexino geoneutrino data is highlighted.

description: The Galactic Black hole candidate XTE J1752-223 was observed during the decay of its 2009 outburst with the Suzaku and XMM-Newton observatories. The observed spectra are consistent with the source being in the ''intermediate`` and ''low-hard state`` respectively. The presence of a strong, relativistic iron emission line is clearly detected in both observations and the line profiles are found to be remarkably consistent and robust to a variety of continuum models. This strongly points to the compact object in \j\ being a stellar-mass black hole accretor and not a neutron star. Physically-motivated and self-consistent reflection models for the Fe-\ka\ emission-line profile and disk reflection spectrum rule out either a non-rotating, Schwarzchild black hole or a maximally rotating, Kerr black hole at greater than 3sigma level of confidence. Using a fully relativistic line function in which the black hole spin parameter is a variable, we have formally constrained the spin parameter to be $0.52\pm0.11 (1σ)$. Furthermore, we show that the source in the low--hard state still requires an optically--thick disk component having a luminosity which is consistent with the $L\propto T^4$ relation expected for a thin disk extending down to the inner--most stable circular orbit. Our result is in contrast to the prevailing paradigm that the disk is truncated in the low-hard state.

description: Nemoura viki Lillehammer 1972 Finnmark, Kautokeino, Emmatjernbekken, 29.vi.1972, 55 imagos, leg. A. Lillehammer [labelled P2694: ethanol, specimens stored individually in numbered vials, together with their detached right forewing; slide-mounted epiprocts specimens no. 49-52]; slidemounted epiproct of an additional, unlabelled specimen. Only records from northernmost parts of Finland and Norway were known to Lillehammer (1988:118). Later, Johansson and Nilsson (1989, 1994) reported isolated finds of N. viki from the Swedish province of Västerbotten, 500 km south of the previously reported distribution. The Artskart database includes two collection-based records from the province of Troms in northern Norway. In all, there are very few records of this taxon. By all likelihood all specimens at the NHM have been identified by Lillehammer, but this is not documented. One of the slide-mounted epiprocts is shown in Fig. 3. The type specimens of N. viki appear to be missing (see below). The specimens used for the description of the nymphs (Lillehammer 1986) have not been located either.

description: Optimized, necessary and sufficient conditions for the identification of the Schmidt number will be derived in terms of general Hermitian operators. These conditions apply to arbitrary mixed quantum states. The optimization procedure delivers equations similar to the eigenvalue problem of an operator. The properties of the solution of these equations will be studied. We solve these equations for classes of operators. The solutions will be applied to phase randomized two-mode squeezed-vacuum states in continuous variable systems.

L. Boumans, T. Ekrem & S. Roth, det. L. Boumans. This species is widespread in Europe (Illies 1978), but in Scandinavia it is restricted to the northernmost parts as it reached the peninsula only from the northeast (Lillehammer 1988). The older material at the NHM contains only a single specimen collected during the Pasvik expedition in 1966. New samples collected in 2010 indicate that the species is currently not rare in Finnmark.

description: We employ a general Lagrange model to describe the chiral optical properties of stereometamaterials. We derive the elliptical eigenstates of a twisted stacked split-ring resonator, taking phase retardation into account. Through this approach, we obtain a powerful Jones matrix formalism which can be used to calculate the polarization rotation, ellipticity, and circular dichroism of transmitted waves through stereometamaterials at any incident polarization. Our experimental measurements agree well with our model.

The role of talin, a master regulator of integrin-dependent morphogenesis, in the Drosophila embryo.
Creators: name: Ellis, Stephanie Jane
Publisher: name: University of British Columbia
Year: 2014

description: The morphogenesis and maintenance of three-dimensional tissue architecture requires intricate, coordinated regulation of cell shape, position, and proliferation. Cell adhesion molecules, which mediate the attachment of cells both to one another (Cell-Cell adhesion) and to their surrounding extra-cellular matrix (Cell-ECM adhesion), are central regulators of morphogenesis during development and homeostasis. Integrins are the major family of cell- ECM adhesion receptors in metazoans and connect between ECM ligands and the actin cytoskeleton via an intracellular integrin adhesion complex (IAC). Integrins contribute to an impressive range of cellular processes and tissue behaviours, but the molecular mechanisms underlying diverse integrin function are not well described. In this thesis, I aim to shed light on this matter via a structure/function-based analysis of the core IAC component, Talin, in the context of Drosophila melanogaster embryogenesis. Talin forms a direct structural link between integrins and the actin cytoskeleton and has been implicated as a regulator of integrin affinity for ECM ligands in the context of single cells in culture. My analysis reveals that in the context of a developing, intact organism, the principal functions of talin are to control IAC assembly, dynamics, and linkage to the cytoskeleton. Using a unique combination of forward and reverse genetics, live imaging, and immunofluorescence, I have uncovered novel insights into the role of talin as a regulator of integrin-mediated adhesion in vivo. I show that different domains of talin contribute to fine- tuning of integrin function in a tissue- and process-specific manner. The specific findings of this work are as follows: (1) two structurally distinct interactions between integrin and talin confer a developmentally regulated switch between modes of transient and stable adhesion (2) autoinhibitory control of talin provides a way to downregulate adhesion during morphogenesis ii and (3) the talin FERM domain primarily confers its effect on integrins through promoting receptor clustering and adhesion scaffolding rather than acting to increase integrin ligand affinity. In general, my work demonstrates how the interactions that talin makes within the integrin adhesion complex has major consequences for integrin function and thus for developmental control of tissue formation and maintenance.

A finite-temperature liquid-quasicrystal transition in a lattice model

description: We consider a tiling model of the two-dimensional square-lattice, where each site is tiled with one of the sixteen Wang tiles. The ground states of this model are all quasi-periodic. The systems undergoes a disorder to quasi-periodicity phase transition at finite temperature. Introducing a proper order-parameter, we study the system at criticality, and extract the critical exponents characterizing the transition. The exponents obtained are consistent with hyper-scaling.

description: We develop a model to describe the properties of random assemblies of polydisperse hard spheres. We show that the key features to describe the system are (i) the dependence between the free volume of a sphere and the various coordination numbers between the species, and (ii) the dependence of the coordination numbers with the concentration of species; quantities that are calculated analytically. The model predicts the density of random close packing and random loose packing of polydisperse systems for a given distribution of ball size and describes packings for any interparticle friction coefficient. The formalism allows to determine the optimal packing over different distributions and may help to treat packing problems of non-spherical particles which are notoriously difficult to solve.
