description: Libertia Spreng. is a genus of monocotyledonous perennial herbs of bicentric distribution, from Australasia and South America. It contains sixteen species, with seven found in South America, seven endemic to New Zealand, one endemic to Australia, and one found in New Zealand, Tasmania, Australia, and New Guinea. Two species, L. flaccidifolia Blanchon and Weaver and L. cranwelliae Blanchon, Murray, and Braggins, are listed as Nationally Critical in New Zealand and L. peregrinans Cockayne and Allan is listed as Nationally Vulnerable. No South American species has been assessed for conservation status. The genus is best defined by its uniform n=19 chromosome count cytologically and 6 paired tepals morphologically. Polyploidy and hybridization have played a critical role in the development of Libertia as a genus. Polyploidy is extremely common in perennial herbs, particularly the tribe Sisyrinchiae. In Libertia, only two of the eleven studied species are diploid, the remaining nine ranging from tetraploid to dodecaploid. The higher levels of polyploidy are particularly common in New Zealand, with all seven endemics being either hexaploid or dodecaploid. These levels of polyploidy are suggestive of a historic retreat into mountains during New Zealand’s glacial periods, as polyploids are more productive and reproductively successful than diploids in high altitudes. Further study should include a phylogenetic study of Libertia, necessary to establish clades and relations intragenerically. Future research in Libertia should put a focus on South American studies, in particular the identification of clades within L. chilensis (Molina) Gunckel and the confirmation of chromosome count within the Juan Fernandez Islands group of L. chilensis. Establishment of a united and publicly available species description for the South American species is necessary as well.
Examining the characteristics of the Igg antibody response generated during early HIV-1 infection using molecular cloning techniques

description: There is much interest in the possible use of broadly neutralising antibodies (BNAbs) isolated from chronically infected HIV-1 patients to reduce the HIV-1 latent reservoir and to serve as a tool in vaccine design. However, the RV144 trial, the only HIV vaccine efficacy trial to date to show any protection, has highlighted the potential importance of non-neutralising antibodies and IgG subclass in HIV-1 control, whilst anti-HIV-1 antibodies from early infection have been less well characterised. The aims of this project were to generate monoclonal antibodies from longitudinal samples of an early HIV-1 infected patient in multiple IgG subclasses, and to analyse their characteristics and functions. Plasmablasts from an early HIV-1 infected patient at multiple time points were single cell sorted, and using molecular cloning techniques IgG1 monoclonal antibodies were isolated and tested for reactivity to HIV-1. Of 177 monoclonal antibodies, 2.82% were found to be HIV-1 specific. The distribution of heavy and light gene family usage was similar in HIV-1 specific and non-specific antibodies, whilst the number of nucleotide and amino acid mutations only increased over time in the non-specific antibodies. IgG1 expression vectors were modified to produce IgG2, IgG3, and IgG4 vectors, allowing patient derived anti-HIV-1 monoclonal antibodies and several well characterised BNABs to be generated in each of these subclasses. When tested using the RFADCC assay, one patient derived monoclonal antibody in the IgG1 and IgG3 subclasses, and one BNAb in the IgG3 subclass mediated weak ADCC activity. Results have demonstrated that HIV-specific and non-specific antibodies isolated from early infection follow the same VH gene family usage trends, and that early infection anti-HIV IgG3 monoclonal antibodies may mediate weak ADCC activity. Furthermore, the IgG2-4 expression vectors now allow the rapid generation of antibodies in multiple subclasses, and may have the potential to generate more potent therapeutic monoclonal antibodies.

description: Based on a deep ROSAT HRI observation, we have detected a pulsed signal in the 0.1-2 keV band from PSR J0537-6910 --- the recently discovered pulsar associated with the supernova remnant N157B in the Large Magellanic Cloud. The measured pulse period 0.01611548182 ms (+- 0.02 ns), Epoch MJD 50540.5, gives a revised linear spin-down rate of $5.1271 \times 10^{-14} s s^{-1}$, slightly greater than the previously derived value. The narrow pulse shape (FWHM = 10% duty cycle) in the ROSAT band resembles those seen in both XTE and ASCA data (> 2 keV), but there is also marginal evidence for an interpulse. This ROSAT detection enables us to locate the pulsar at R.A., Dec (J2000) = $5^h37^m47^s.2, -69^\circ 10' 23''$. With its uncertainty $\sim 3''$, this position coincides with the centroid of a compact X-ray source. But the pulsed emission accounts for only about 10% of the source luminosity $\sim 2 \times 10^{36} ergs^{-1}$ in the 0.1-2 keV band. These results support our previous suggestions: (1) The pulsar is moving at a high velocity ($\sim 10^3 km/s$); (2) A bow shock, formed around the pulsar, is responsible for most of the X-ray emission from the source; (3) A collimated outflow from the bow shock region powers a pulsar wind nebula that accounts for an elongated non-thermal radio and X-ray feature to the northwest of the pulsar.

description: Computations in high-dimensional spaces can often be realized only approximately, using a certain number of projections onto lower dimensional subspaces or sampling from distributions. In this paper, we are interested in pairs of real-valued functions $(F,f)$ on $[0,\infty)$ that are related by the projection/slicing formula $F (\| x \|) = \mathbb E_ξ \big[ f \big(|\langle x,ξ\rangle| \big) \big]$ for $x\in\mathbb R^d$, where the expectation value is taken over uniformly distributed directions in $\mathbb R^d$. While it is known that $F$ can be obtained from $f$ by an Abel-like integral formula, we construct conversely $f$ from given $F$ using their Fourier transforms. First, we consider the relation between $F$ and $f$ for radial functions $F(\| \cdot\| )$ that are Fourier transforms of $L^1$ functions. Besides $d$- and one-dimensional Fourier transforms, it relies on a rotation operator, an averaging operator and a multiplication operator to manage the walk from $d$ to one dimension in the Fourier space. Then, we generalize the results to tempered distributions, where we are mainly interested in radial regular tempered distributions. Based on Bochner's theorem, this includes positive definite functions $F(\| \cdot\| )$ and, by the theory of fractional derivatives, also functions $F$ whose derivative of order $\lfloor d/2\rfloor$ is slowly increasing and continuous.

description: The systematic errors in the virial mass-to-light ratio, M_v/L, of galaxy clusters as an estimator of the field M/L value are assessed. We overlay 14 clusters in redshift space to create an ensemble cluster which averages over substructure and asymmetries. The combined sample, including background, contains about 1150 galaxies, extending to a projected radius of about twice r_200. The radius r_200, defined as where the mean interior density is 200 times the critical density, is expected to contain the bulk of the virialized cluster mass. The dynamically derived M(r_200)/L(r_200) of the ensemble is 0.82+/-0.14 . The M_v/L overestimate is attributed to not taking into account the surface pressure term in the virial equation. Under the assumption that the velocity anisotropy parameter is in the range 0<=β<=2/3, the galaxy distribution accurately traces the mass profile beyond about the central 0.3r_200. There are no color or luminosity gradients in the galaxy population beyond 2r_200, but there is 0.11+/-0.05 mag fading in the r band luminosities between the field and cluster galaxies. We correct the cluster virial mass-to-light ratio, M_v/L=289+/-50 h\msun/\lsun (calculated assuming q_0=0.1), for the biases in M_v and mean luminosity to estimate the field M/L=213+/-59 h\msun/\lsun. With our self-consistently derived field luminosity density, j/ρ_c=1136+/-138 h\msun/\lsun (at z~1/3), the corrected M/L indicates Ω_0=0.19+/-0.06+/-0.04 (formal 1σrandom error and estimated potential systematic errors).

Development of strontium molybdate and strontium niobate for plasmonic devices
Creators: name: Wells, Matthew Philip
Publisher: name: Imperial College London
Year: 2018

description: Plasmonic phenomena have been proposed as a mechanism for the advancement of a wide range of technologies, ranging from solar energy harvesting, optical and chemical sensing, to high-speed computing. A review of literature on the subject however reveals that, despite the strong motivation for the development of plasmonic technologies, there exist relatively few practical plasmonic devices. This is substantially due to a lack of appropriate materials suitable for use in the relevant frequency regime of each application. Consequently, investigations are carried out into two potential alternative plasmonic materials, namely strontium molybdate (SrMoO3) and strontium niobate (SrNbO3). Thin films of both materials, deposited by pulsed laser deposition (PLD), are comprehensively characterised by spectroscopic ellipsometry, x-ray diffraction, atomic force microscopy, scanning electron microscopy, and secondary ion mass spectrometry, along with DC resistivity and AC Hall effect measurements. Both strontium molybdate and strontium niobate are shown to exhibit optical properties well suited to plasmonic applications operating in the visible to near infrared spectral regime, particularly those utilising the local heat generation capabilities of plasmonic nanoparticles. However further experiments identify a propensity to oxidation present in both materials, thus restricting their use in a number of high temperature applications. Moreover, strontium molybdate is shown to degrade rapidly when exposed to water, further limiting its range of practical applicability. Additional experiments seek to address these prohibitive instabilities; specifically, the degradation mechanisms of strontium molybdate under exposure to high temperatures and in water are both found to be significantly suppressed by the introduction of an in situ nitrogen annealing step to the PLD routine. This is found to induce an additional crystalline phase at the surface of the film which acts as a passivation layer, enabling the material’s desirable optical properties to be retained to temperatures in excess of 600° C. Similarly, investigations are conducted into the fabrication and properties of multilayer strontium molybdate/strontium niobate structures, from which it is found that the degradation of strontium molybdate in water can be entirely mitigated by the addition of a 10 nm strontium niobate capping layer. This development facilitates the use of thin-film patterning processes such as colloidal lithography, thus enabling the fabrication of plasmonic nanoantennas from each material. In summary, this thesis describes the introduction of two new materials to the field of plasmonics. The specific applications to which they may be best suited are identified, along with their principal degradation mechanisms, and potential mitigation techniques for these degradations.

description: We give a brief review of current theoretical work in galaxy formation. Recent results from N-body and N-body/hydrodynamic simulations, and from semianalytic modelling are discussed. We present updated versions of some figures from Cole et al (1994). In particular, we show the effect of using the revised stellar population synthesis model of Bruzual and Charlot, which results in a much better match to the observed colour distribution of galaxies than before. We also compare the model output with recently available data on the galaxy luminosity function and the redshift distribution of galaxies in the B and K bands. The form of the Tully-Fisher relation at high redshift predicted by our semi-analytic scheme for galaxy formation is given.

description: Turloughs, the ephemeral lakes of Ireland, are unique landforms found in karstic limestone environments that form a dynamic habitat. By flooding seasonally, turloughs support a distinct flora that is capable of withstanding a highly variable environment. The Geological Survey of Ireland recognized 304 turloughs in 2006, and a further one has been designated in Wales. Turloughs are priority habitats under the EU Habitats Directive (2013) and thus turloughs designated as qualifying interests require monitoring. In this study, a group of small depressions in the limestone pavements of the East Burren SAC, Co. Clare were assessed to determine if the features function as turloughs and necessitate ongoing monitoring.
 The southern Mullaghmore site is made up of seven features to the south of Mullaghmore, and scattered across the limestone grasslands and pavements between Lough Cuil Reasc and Travann Lough. The features were mapped and surveyed for vegetation community composition through quadrats representing a minimum 2% of the area of the feature. Vegetation communities were then assembled through non-metric scaling (NMS) ordination and indicator species analysis (ISA) to represent the vegetation of each individual feature and allow for identification of an inundation gradient where present. These communities and species of indicator or conservation interest were then related to previous turlough studies. The southern Mullaghmore site holds high levels of diversity in these small landforms, with several unique features showing turlough-like function, with distinctly diverse vegetation communities. Feature #1 in particular was shown to resemble a turlough and should be further studied and monitored for changes to its conservation status, in relation to its pressures.

description: We study the Heisenberg $S=1/2$ chain with random ferro- and antiferromagnetic couplings using quantum Monte Carlo simulations at ultra-low temperatures, converging to the ground state. Finite-size scaling of correlation functions and excitation gaps demonstrate an exotic critical state in qualitative agreement with previous strong-disorder renormalization group calculations but with scaling exponents depending on the coupling distribution. We find dual scaling regimes of the transverse correlations versus the distance, with an $L$ independent form $C(r)=r^{-μ}$ for $r \ll L$ and $C(r,L)=L^{-η}f(r/L)$ for $r/L > 0$, where $μ> η$ and the scaling function is delivered by our analysis. These results are at variance with previous spin-wave and density-matrix renormalization group calculations, thus highlighting the power of unbiased quantum Monte Carlo simulations.

description: Refractive interstellar scintillation (RISS) is thought to be the cause behind a variety of phenomena seen at radio wavelengths in pulsars and compact radio sources. Though there is substantial observational data to support several consequences of it, the quantitative predictions from theories have not been thoroughly tested. In this paper, data from our long-term scintillation study of 18 pulsars are used to test the predictions. The fluctuations of decorrelation bandwidth ($ν_d$), scintillation time scale ($τ_d$) and flux density (F) are examined for their cross-correlations and compared with the predictions. The theory predicts a strong correlation between $ν_d$ and $τ_d$, and strong anti-correlations between $ν_d$ and F, and $τ_d$ and F. For 5 pulsars, we see a reasonable agreement. There is considerable difficulty in reconciling the results for the rest of the pulsars. Our analysis shows the underlying noise sources can sometimes reduce the correlation, but cannot cause an absence of correlation. It is also unlikely that the poor flux correlations arise from a hitherto unrecognized intrinsic flux variations. For PSR B0834+06, which shows anomalous behaviour of persistent drift slopes, positive correlation is found between $τ_d$ and the drift-corrected $ν_d$. Many pulsars show an anti-correlation between $ν_d$ and the drift slope, and this is in accordance with the simple models of RISS. The detections of correlated variations of observables and a reasonable agreement between the predicted and measured correlations for some pulsars confirm RISS as the primary cause of the observed fluctuations. However, the complexity seen with the detailed results suggests the necessity of more comprehensive theoretical treatments for describing refractive fluctuations and their correlations.

Activation of Discoidin Domain Receptors by collagen VI and collagen I fibrils
Creators: name: Gavriilidou, Despoina
Publisher: name: Imperial College London
Year: 2017

description: Discoidin domain receptors (DDRs) are members of the Receptor Tyrosine Kinase (RTK) family. There are two DDRs, DDR1 and DDR2. In embryo development, DDR1 function is vital for mammary gland development, whereas DDR2 is important in long bone growth. The DDRs also have key roles in several cellular functions, such as cell migration, adhesion, proliferation and matrix remodeling. The DDRs are unique RTK members due to the fact that they are activated by an extracellular matrix component, collagen. It is well known that the DDRs are activated by fibrillar collagens, such as collagen I, when present as single triple helices. However, it is less clear whether collagen I fibrils or fibers, the form in which collagen I is present in tissues, can act as functional DDR ligands and induce DDR phosphorylation. In this thesis, I show that DDR1 activation is induced by collagen I fibrils generated in vitro from different sources, and furthermore by extracellular matrix secreted from fibroblastic cells. I also show that DDR2 is activated to a much lower extent in comparison to DDR1. Another collagen type that is present in many tissues is collagen VI. Collagen VI has not been characterized as a DDR ligand. Collagen VI is secreted in the form of tetramers to extracellular matrices, where it associates to form microfibrils. In this thesis, I show that collagen VI tetramers and microfibrils bind strongly to both DDRs. However, they can induce only DDR1 phosphorylation, not DDR2 phosphorylation. Our preliminary data further suggest that the triple-helical region in collagen VI is the functional region that promotes DDR1 activation. Furthermore, I show that collagen VI binds to DDR2 by occupying another binding site than the fibrillar binding site. Finally, preliminary experiments suggest that collagen VI microfibrils can inhibit collagen I-induced DDR2 autophosphorylation. These data suggest that collagen VI binding to DDR2 could serve as a limiting factor for DDR2 activation in pathological conditions, such as osteoarthritis.

description: We present imaging polarimetry of the extremely luminous, redshift 2.3 IRAS source FSC10214+4724. The observations were obtained with HST's Faint Object Camera in the F437M filter, which is free of strong emission lines. The 0.7 arcsec long arc is unresolved to 0.04 arcsec FWHM in the transverse direction, and has an integrated polarization of 28 +/- 3 percent, in good agreement with ground-based observations. The polarization position angle varies along the arc by up to 35 deg. The overall position angle is 62 +/- 3 deg east of north. No counterimage is detected to B = 27.5 mag ($3σ$), giving an observed arc to counterimage flux ratio greater than 250, considerably greater than the flux ratio of 100 measured previously in the I-band. This implies that the configuration of the object in the source plane at the B-band is different from that at I-band, and/or that the lensing galaxy is dusty.

In light of the available data, we consider various scenarios to explain the properties of 3C 324, as well as evidence for the presence of dust which may obscure the central active nucleus and scatter its light to produce the polarized, aligned continuum seen in the rest-frame UV.

description: We study the exact ground states of the Su--Schrieffer--Heeger open chain and of the Kitaev open chain, using the Variational Quantum Eigensolver (VQE) algorithm. These models host symmetry-protected topological phases, characterized by edge modes with vanishing single-particle energy in the thermodynamic limit. The same fact prevents the standard VQE algorithm from converging to the correct ground state for finite chains, since it is quasi-degenerate in energy with other many-body states. Notably, this quasi-degeneracy cannot be removed by small perturbations, as in typical spin systems. We address this issue by imposing appropriate constraints on the VQE evolution and constructing appropriate variational circuits, to restrict the probed portion of the Hilbert space along the same evolution. These constraints stem from both general properties of the topological phases and of the studied Hamiltonians. In this way, the improved VQE algorithm achieves an accurate convergence to the exact ground states in each phase. The present approach promises large applicability, also to realistic systems with different topologies and/or not easily removable degeneracies, thanks to the very high fidelity achievable also on systems with a relatively high number of qubits.

The role of the IKK-2/NF-kB signaling in cigarette smoke-induced airway inflammation
Creators: name: Rastrick, Joseph
Publisher: name: Imperial College London
Year: 2012

description: Chronic Obstructive Pulmonary Disease (COPD) is an inflammatory lung disease largely associated with cigarette smoke (CS) exposure. The mechanism by which CS leads to the pathogenesis of COPD remains unclear, however many inflammatory mediators present in the COPD lung are thought to be regulated by the transcription factor Nuclear Factor-kappaB (NF-kB) and it’s upstream signalling kinase, Inhibitor of kB kinase-2 (IKK-2). The IKK- 2/NF-kB signalling pathway may therefore be crucial in the pathogenesis of the inflammation associated with COPD. To investigate this hypothesis, mice were exposed to acute or sub-chronic CS and inflammatory end-points, including NF-kB pathway activation were measured. Acute CS generated a predominantly neutrophilic response in the lung, whereas the inflammatory phenotype following sub-chronic exposure was more persistent and included monocytes/macrophages and lymphocytes. In contrast to lipopolysaccharide (LPS)-induced lung inflammation however, neither acute nor sub-chronic CS generated an increase in NF-kB:DNA association in whole lung nuclear extracts. To determine if distinct cell types were responsible for a CS-induced change in NF-kB:DNA association, that could not be detected in whole lung nuclear extracts, mice lacking IKK-2 exclusively in the airway epithelium or in myeloid-derived cells were exposed to acute and sub-chronic CS. These mice were shown to have reduced IKK-2 gene expression in the targeted cell types and both strains showed a functional decrease in LPS-induced NF-kB:DNA association. CS-induced lung inflammation however, was not reduced by ablation of IKK-2 in either cell type. This was confirmed using 2 small molecule, structurally distinct 3 IKK-2 specific inhibitors, with proven efficacy against LPS-induced NF-kB:DNA association and neutrophilia. In support of these findings, lung tissue taken from human COPD patients also showed no change in NF-kB:DNA association compared to ‘healthy smokers’ and non-smokers, leading to the conclusion that contrary to previous reports, NF-kB may not play a prominent role in CS-induced lung inflammation.

description: The applications of superconducting cable or magnet require that the superconductors are made into wires or tapes. For cuprate superconductors, this is a big challenge because of the strong flux motion induced by high anisotropy, very short coherence length and strong thermal fluctuation, etc. One of the ways is to fabricate superconducting films on flexible metallic tapes with oxide buffer layers. The successful one so far is the REBa$_2$Cu$_3$O$_7$ (REBCO, RE=rare earth elements) films in tape form, as called the coated conductors. While the superconducting transition temperature of REBCO system is limited to about 90 K. Here we report the successful fabrication of another new non-toxic superconducting film, namely (Cu,C)Ba$_{2}$Ca$_{2}$Cu$_3$O$_{9\pmδ}$ on these flexible metallic tapes with LaMnO$_3$ and CeO$_2$ as the top layers. The onset superconducting transition occurs at 112 K and 110 K, and the zero-resistance transition temperatures are about 96 K and 98 K, respectively. The temperature dependent resistivity under magnetic fields in different directions reveal a relatively small anisotropy. Further optimization of the films will improve the zero resistance transition temperature, thus can also improve the characteristic properties for applications. Our results show that the (Cu,C)Ba$_{2}$Ca$_{2}$Cu$_3$O$_{9\pmδ}$ is a promising candidate material for the high power applications in liquid nitrogen temperature region.

description: O presente artigo propõe uma discussão entre as temáticas processos de negócios, gestão de documentos e fluxo documental. O objetivo do diálogo está baseado na necessidade de i) esclarecer a relação entre o processo de negócios, o gerenciamento de documentos e o fluxo documental, e ii) explicar a relevância de considerar os documentos como portadores de conteúdo dinâmico, envolvendo seu próprio fluxo de aprovação e ciclo de vida muitas vezes não completamente ligados ao processo em que os mesmos documentos participam. Para tal, será elaborado um bem fundamentado arcabouço teórico que subsidiará a análise comparativa prática de dois modelos de processos de negócio, onde apenas um deles é contemplado pelos estudos documentais do processo. A construção teórica será capaz de alinhar diferentes áreas do conhecimento à Ciência da Informação, além de enriquecer a sua produção em relação à gestão de informação em relatos de casos. De forma prática, será capaz de demonstrar o impacto da ausência de estudos documentais em projetos de modelagem de processos e contribuir para a prática do profissional da informação.
Observational Searches for Solar g-modes: Some Theoretical Considerations

description: We argue that the solar g-modes are unlikely to have caused the discrete peaks in the power spectrum of the solar wind flux observed by Thomson et al. (1995). The lower limit to the energy of individual g-modes, using the amplitudes given by Thomson et al., is estimated to be at least 10$^{36}$ erg for low order g-modes; the resulting surface velocity amplitude is at least 50 cm s$^{-1}$, larger than the observational upper limit (5 cm s$^{-1}$). We suggest that the most likely source for the excitation of solar g-modes is turbulent stresses in the convection zone. The surface velocity amplitude of low degree and low order g-modes resulting from this process is estimated to be of order 10$^{-2}$ cm s$^{-1}$. This amplitude is interestingly close to the detection threshold of the SOHO satellite. The long lifetime of g-modes ($\sim 10^6$ years for low order modes) should be helpful in detecting these small amplitude pulsations.

description: The photometric errors of the external calibrator for the FIRAS instrument on the COBE are smaller than the measurement errors on the cosmic microwave background (CMBR) spectrum (typically 0.02 MJy/sr, 1 sigma), and smaller than 0.01% of the peak brightness of the CMBR. The calibrator is a re-entrant cone, shaped like a trumpet mute, made of Eccosorb iron-loaded epoxy. It fills the entire beam of the instrument and is the source of its accuracy. Its known errors are caused by reflections, temperature gradients, and leakage through the material and around the edge. Estimates and limits are given for all known error sources. Improvements in understanding the temperature measurements of the calibrator allow an improved CMBR temperature determination of 2.725 +/- 0.002 K.

description: We expand our recent work on the outer entropy, a holographic coarse-grained entropy defined by maximizing the boundary entropy while fixing the classical bulk data outside some surface. When the surface is marginally trapped and satisfies certain "minimar" conditions, we prove that the outer entropy is exactly equal to a quarter the area (while for other classes of surfaces, the area gives an upper or lower bound). We explicitly construct the entropy-maximizing interior of a minimar surface, and show that it satisfies the appropriate junction conditions. This provides a statistical explanation for the area-increase law for spacelike holographic screens foliated by minimar surfaces. Our construction also provides an interpretation of the area for a class of non-minimal extremal surfaces. On the boundary side, we define an increasing simple entropy by maximizing the entropy subject to a set of "simple experiments" performed after some time. We show (to all orders in perturbation theory around equilibrium) that the simple entropy is the boundary dual to our bulk construction.

Bayesian methods for the analysis of ultra-high-energy cosmic rays
Creators: name: Khanin, Alexander
Publisher: name: Imperial College London
Year: 2016

description: The origins of ultra-high-energy cosmic rays (UHECRs) are one of the open puzzles of astrophysics. A number of plausible candidates, such as active galactic nuclei (AGNs) have been discussed, but no clear consensus has been reached. One way to assess the different hypotheses is by analyzing the UHECR arrival directions. Recently, a small number of studies have begun applying Bayesian methodologies to this problem, forming the first steps in the development of a comprehensive Bayesian framework for the study of UHECRs. In this work, we have developed two Bayesian methods to study this question, and have applied them to UHECRs from the Pierre Auger Observatory (PAO). The first method was a Bayesian approach to studying the catalogue-independent clustering of UHECRs. Previously, this had been difficult as there is no well motivated clustered model that can be used in a Bayesian model comparison. We have resolved this difficulty by developing a multi-step approach that derives such a model from a sub-set of the data. This approach could have broad applications for anisotropy searches in other areas of astronomy. Our results were consistent with both isotropic and clustered models. The second was a Bayesian method that was aimed to find associations between UHECR arrival directions and source catalogues. It was an extension of a previous Bayesian study, but analyzed a greater data set, used a more refined UHECR model, and was generalized to be applicable to a greater variety of source catalogues. Our results were broadly consistent with previous work, with the purely isotropic UHECR models being disfavoured for reasonable parameter ranges. It will be of great interest to apply our methods to samples of greater size. The extended UHECR samples that will be available in the near future should be sufficient for our methods to determine the origins of the UHECRs.

description: Avaliar e reavaliar a qualidade de ajustar as necessidades de sua comunidade são atividades necessárias para qualquer biblioteca. Este estudo utiliza a métrica Servqual – de Parasuraman, Zeithaml e Berry (1985), para analisar as expectativas e percepção dos associados da Bibiblioteca Transcol em relação aos serviços ofertados pelos módulos bibliotecários nos términos de transporte públicos do município de Vila Velha. Este método propõe a analise da matriz importância & desempenho para a gestão das bibliotecas públicas em relação às cinco dimensões de qualidade: confiança, tangibilidade, sensibilidade, segurança e empatia. A metodologia desta investigação tem caráter descritivo com o uso da técnica de incidente crítico. Os resultados obtidos indicam que os associados da biblioteca atribuem maior importância à dimensão ‘segurança’ no que refere à prestação de serviços em informação.
