Creators: name: Pereira, Armando De Sousa
Publisher: name: Lusitania Sacra
Year: 2001

description: Este estudo tem por objectivo analisar o significado da presença de temas, figuras e expressões bíblicas nos textos historiográficos do mosteiro de Santa Cruz de Coimbra, redigidos em finais do século XII. Numa época de estagnação e retrocesso da Reconquista, dadas as violentas investidas muçulmanas dos Almóadas, os monges utilizam, selectivamente, passagens dos livros do Antigo Testamento para fundamentarem a legitimidade da realeza de Afonso I de Portugal e as suas conquistas contra o Islão, enquadrando a guerra e o nascimento do reino no âmbito da providência divina.

Exploring residential care aide experiences with oral malodour in long-term care
Creators: name: Dhami, Charanpreet
Publisher: name: University of British Columbia
Year: 2016

description: OBJECTIVE: Numerous studies to date have revealed that the oral health status of people living in long-term care (LTC) facilities is poor. As an elderly resident’s ability to perform personal oral care tasks declines, so does their oral health mainly in the form of periodontal disease and caries. Poor oral health also contributes to oral malodour (foul odour emanating from an individual’s breath), which negatively impacts an individual’s verbal interactions and social acceptability. There is evidence suggesting that the geriatric population is more prone to oral malodour. Studies done on oral malodour have looked at aspects such as sources, measurement techniques, management strategies and how malodour impacts the individual suffering from it. However, a deeper understanding of the impact of oral malodour on care givers has yet to be investigated. The following study investigated using an interpretive qualitative approach and a social constructivism interpretive framework the question: what experiences do residential care aides (RCAs) have with individuals living with oral malodour in a LTC facility? METHODS: The study was conducted through face-to-face interviews with RCAs, which were recorded and transcribed verbatim, observations of RCAs in their work environment, as well as RCA personal logs of their daily experiences with odour during caregiving. Thereafter, data was analyzed and coded for emerging themes. RESULTS: Five main themes emerged that described the experiences of RCAs working with residents with odour; challenges of care giving, knowledge of oral malodour management, attitudes and behaviours, attitude and job satisfaction, culture and odour. Collectively these factors affected the quality of interactions the RCA had with the resident. CONCLUSION: Oral malodour among residents was a difficult condition for most of the participants in this study to deal with, and appeared to impact both the quality and quantity of care they provided. Knowledge and understanding of the sources of oral malodour and how to manage it were found to be one of the factors that influenced the provision of care among the participants. Participant attitude, cultural beliefs and organizational beliefs influenced both the importance of oral malodour and how it was managed.
Novel grooved substrata stimulate macrophage fusion, CCL2 and MMP-9 secretion

Publisher: name: University of British Columbia
Year: 2016

description: Monocyte-derived macrophages arrive early at a newly implanted device and affect the performance of implants by regulating immune responses. Macrophages are “plastic” cells that exhibit a spectrum of functions between two quintessential phenotypes: (1) the classically activated (M1) phenotype associated with classical inflammatory responses and (2) the alternatively activated (M2) phenotype involved in wound healing or immunoregulatory behavior. Rough surface topographies on implants attract macrophages but the influence of topography on macrophage fusion to produce multinucleated giant cells (MGCs) and foreign body giant cells (FBGCs) is unclear. Previous studies have shown topography induced macrophage polarization and changes in cell shape as well as differential activation of cell signaling pathways. In this study, the effects of novel grooved substrata, G1 and G2, on changes in cell shape, gene expression, cyto/chemokine secretion and cell fusion were studied. G1 and G2 surfaces were fabricated by anisotropic etching of silicon <110> crystals, without the use of photolithographic patterning, and extensively characterized by optical profilometry to determine the roughness parameter Ra and isotropy parameters Str and Sal (G1: Ra 0.10 μm, Str 0.03, Sal 2.1 μm; G2: Ra 1.2 μm, Str 0.08, Sal 5.8 μm). RAW 264.7 macrophages were cultured on G1, G2, and smooth control (Pol) epoxy substrata for one and five days. Cells on the grooved surfaces exhibited cell morphology similar to M2 macrophages that were produced by IL-4 treatment. Cell alignment with the grooves increased with surface directionality and roughness as well as time in culture. Expression of macrophage chemoattractants CCL2 and CCL4 increased at the gene and protein level and the secretion of fusion mediators CCL2 and MMP-9 increased with time on the grooved surfaces. Relative to the Pol surface, an increased proportion of multinucleated cells was observed on the grooved surfaces at Day 5. Collectively, these in vitro results demonstrated that topography dependent macrophage responses resulted in differential secretion of macrophage attractant chemokines and soluble mediators involved in cell fusion that may explain the observed accumulation of macrophages and MGCs on rough surfaced implants in vivo.

Early cistercian polyphony: a newly-discovered source
Creators: name: Ferreira, Manuel Pedro
Publisher: name: Lusitania Sacra
Year: 2001

description: This paper presents a two-voice hymn to St. Bernard, found by the author in the Arouca Monastery. This hitherto unpublished hymn, which can be dated around 1225, is the most ancient polyphonic work found so far in Portugal, and one of the oldest examples of polyphony copied in Cistercian manuscripts. To explain its presence in Arouca, the author examines both the local and the international context; the problem of polyphonic practice in the Cistercian Order receives special attention, and several related compositions are transcribed. The musical style of the hymn is then discussed and its peculiar, conservative character put into relief against the background of European polyphonic practice. The interpretative transcription offered is then justified at length.

description: Seafloor spreading is accommodated by volcanic and tectonic processes along the global mid-ocean ridge system. As spreading rate decreases, the influence of volcanism also decreases, and it is unknown whether significant volcanism occurs at all at ultraslow spreading rates (<1.5 cm yr -1). Here we present three-dimensional sonar maps of the Gakkel ridge, Earth's slowest spreading mid-ocean ridge, located in the Arctic basin under the Arctic Ocean ice canopy. We acquired this data using hull-mounted sonars attached to a nuclear-powered submarine, the USS Hawkbill. Sidescan data for the ultraslow-spreading (~1.0 cm yr- 1) eastern Gakkel ridge depict two young volcanoes covering approximately 720 km2 of an otherwise heavily sedimented axial valley. The western volcano coincides with the average location of epicentres for more than 250 teleseismic events detected in 1999, suggesting that an axial eruption was imaged shortly after its occurrence. These findings demonstrate that eruptions along the ultraslow-spreading Gakkel ridge are focused at discrete locations and appear to be more voluminous and occur more frequently than was previously thought.

Novel transport layer characterization and synthesis for proton exchange membrane fuel cells
Creators: name: Todd, Devin Garret Zech
Publisher: name: University of British Columbia
Year: 2016

description: Fuel cells are a promising energy conversion technology compatible with developing renewably sourced primary energy distribution. Proton exchange membrane (PEM) fuel cells are particularly suitable for automotive and portable applications. The present thesis advances novel PEM fuel cell porous transport layer (PTL) characterization and materials research. These layers link macro and nano scales by mediating energy and mass transport between reactant distribution channels and catalyst layers. Contemporary commercial PTLs are limited in selection. Moreover, typical characterization methods ignore essential material anisotropy. Herein, a novel transport layer synthesis concept is introduced. By adapting electrospinning technology, structures with engineered morphology are created. PTLs are produced with fibre diameters from 0.2 to 1.6 µm, and are characterized experimentally ex-situ and in-situ. Electrospun PTLs are shown to deliver 85% of equivalent commercial PTL current densities. Furthermore, the state-of-the-art for electronic resistance measurement of PTLs is improved, with rigorous attention given to the anisotropy of the fibre-based media. Novel method and apparatus provide this information as a function of mechanical strain. PTL in-plane resistivities are a unique contribution, where for commercial materials 4.5x10-⁴ to 1.5x10-⁴ Ω∙m are observed for strains from 0.0 to -0.5 m∙m-¹. Finally, electrospun PTLs are developed to investigate the effect of within-plane anisotropy upon fuel cell performance. Electrospun layers are produced with progressively greater fibre alignment to effect anisotropy. This anisotropy is visualized via microscopy, and quantified using the aforementioned electronic resistivity methods. In-situ results with electrospun PTLs, of anisotropy ratios from 1 to 6, suggest greater performance with average fibre alignment perpendicular to gas distribution channels. The present thesis’ contributions strengthen development of a PTL structure-property-performance relationship. With integration into a cell-level relationship, this can empower rational PEM fuel cell design.

description: We summarize results of a search for X-ray-emitting binary stars in the massive globular cluster Omega Centauri (NGC 5139) using Chandra and HST. ACIS-I imaging reveals 180 X-ray sources, of which we estimate that 45-70 are associated with the cluster. We present 40 identifications, most of which we have obtained using ACS/WFC imaging with HST that covers the central 10'x10' of the cluster. Roughly half of the optical IDs are accreting binary stars, including 9 very faint blue stars that we suggest are cataclysmic variables near the period limit. Another quarter comprise a variety of different systems all likely to contain coronally active stars. The remaining 9 X-ray-bright stars are an intriguing group that appears redward of the red giant branch, with several lying along the anomalous RGB. Future spectroscopic observations should reveal whether these stars are in fact related to the anomalous RGB, or whether they instead represent a large group of "sub-subgiants" such as have been seen in smaller numbers in other globular and open clusters.

A Packet Dropping Mechanism for Efficient Operation of M/M/1 Queues with Selfish Users

description: We consider a fundamental game theoretic problem concerning selfish users contributing packets to an M/M/1 queue. In this game, each user controls its own input rate so as to optimize a desired tradeoff between throughput and delay. We first show that the original game has an inefficient Nash Equilibrium (NE), with a Price of Anarchy (PoA) that scales linearly or worse in the number of users. In order to improve the outcome efficiency, we propose an easily implementable mechanism design whereby the server randomly drops packets with a probability that is a function of the total arrival rate. We show that this results in a modified M/M/1 queueing game that is an ordinal potential game with at least one NE. In particular, for a linear packet dropping function, which is similar to the Random Early Detection (RED) algorithm used in Internet Congestion Control, we prove that there is a unique NE. We also show that the simple best response dynamic converges to this unique equilibrium. Finally, for this scheme, we prove that the social welfare (expressed either as the summation of utilities of all players, or as the summation of the logarithm of utilities of all players) at the equilibrium point can be arbitrarily close to the social welfare at the global optimal point, i.e. the PoA can be made arbitrarily close to 1. We also study the impact of arrival rate estimation error on the PoA through simulations.

description: Recent wide-field near-infrared surveys have uncovered a large number of cool brown dwarfs, extending the temperature sequence down to less than 500 K and constraining the faint end of the luminosity function. One interesting implication of the derived luminosity function is that the brown dwarf census in the immediate (<10 pc) solar neighborhood is still largely incomplete, and some bright (J<16) brown dwarfs remain to be identified in existing surveys. These objects are especially interesting as they are the ones that can be studied in most detail, especially with techniques that require large fluxes (e.g. time-variability, polarimetry, high-resolution spectroscopy) that cannot realistically be applied to objects uncovered by deep surveys. By cross-matching the DENIS and the 2MASS point-source catalogs, we have identified an overlooked brown dwarf -DENIS J081730.0-615520- that is the brightest field mid-T dwarf in the sky (J = 13.6). We present astrometry and spectroscopy follow-up observations of this brown dwarf. Our data indicate a spectral type T6 and a distance -from parallax measurement- of 4.9\pm0.3 pc, placing this mid-T dwarf among the 3 closest isolated brown dwarfs to the Sun.

description: Context: Some O stars are suspected to have to have (weak) magnetic fields because of the observed cyclical variability in their UV wind-lines. However, direct detections of these magnetic fields using optical spectropolarimetry have proven to be very difficult. Aims: Non-thermal radio emission in these objects would most likely be due to synchrotron radiation. As a magnetic field is required for the production of synchrotron radiation, this would be strong evidence for the presence of a magnetic field. Such non-thermal emission has already been observed from the strongly magnetic Ap/Bp stars. Methods: We have performed 6 & 21 cm observations using the WSRT and use these, in combination with archival VLA data at 3.6 cm and results from the literature, to study the radio emission of 5 selected candidate magnetic O stars. Results: Out of our five targets, we have detected three: $ξ$ Per, which shows a non-thermal radio spectrum, and $α$ Cam and $λ$ Cep, which show no evidence of a non-thermal spectrum. In general we find that the observed free-free (thermal) flux of the stellar wind is lower than expected. This is in agreement with recent findings that the mass-loss rates from O stars as derived from the H$α$ line are overestimated because of clumping in the inner part of the stellar wind.

To reform or not to reform : China's hukou reform at the local level
Creators: name: Zhang, Miaofeng
Publisher: name: University of British Columbia
Year: 2016

description: The Chinese government has issued a series of directives of hukou system reform. However, the strength and depth of the hukou reforms at the local level differ greatly across localities. Some local governments refused to reform, while others implemented local reforms either radically or conservatively. Among those that reformed local system, some decided to suspend or alter it and others continued. Thus, the paper asks what accounts for the variance of hukou system reforms across localities. Specifically, the research question is two-fold: 1) regarding the initiation of reforms, why some local governments implemented radical hukou reform, others partially reformed their hukou policies, and still others did not carry out the reform, and 2) as for the maintenance of reform, why, among those that pursued hukou reform, some decided to suspend or alter it while others continued. The paper adopts the comparative case study method and delves into three cases: Zhengzhou, Hohhot, and Fenghua. Different from existing literature that focuses merely on either incentives or disincentives of local hukou reform, this paper brings the political factors in and argues that it is local leaders’ political decisions based on different degrees of pressure of urbanization from upper level governments and different levels of policy adjustability to costs that cause such divergence. What’s more, I contend that the variance of the adjustability to expected costs leads to different outcomes in maintaining hukou reforms.

description: We have chosen the name of GYES, one of the mythological giants with one hundred arms, offspring of Gaia and Uranus, for our instrument study of a multifibre spectrograph for the prime focus of the Canada-France-Hawaii Telescope. Such an instrument could provide an excellent ground-based complement for the Gaia mission and a northern complement to the HERMES project on the AAT. The CFHT is well known for providing a stable prime focus environment, with a large field of view, which has hosted several imaging instruments, but has never hosted a multifibre spectrograph. Building upon the experience gained at GEPI with FLAMES-Giraffe and X-Shooter, we are investigating the feasibility of a high multiplex spectrograph (about 500 fibres) over a field of view 1 degree in diameter. We are investigating an instrument with resolution in the range 15000 to 30000, which should provide accurate chemical abundances for stars down to 16th magnitude and radial velocities, accurate to 1 km/s for fainter stars. The study is led by GEPI-Observatoire de Paris with a contribution from Oxford for the study of the positioner. The financing for the study comes from INSU CSAA and Observatoire de Paris. The conceptual study will be delivered to CFHT for review by October 1st 2010.

description: The flanks of the Southeast Indian Ridge are characterized by anomalously low subsidence rates for the 0–25 Ma period: less than 300 m Ma -1/2 between 101°E and 120°E and less than 260 m Ma-1/2 within the Australian-Antarctic Discordance (AAD), between 120°E and 128°E. The expected along-axis variation in mantle temperature (~50°C) is too small to explain this observation, even when the temperature dependence of the mantle physical properties is accounted for. We successively analyze the effect on subsidence of different factors, such as variations in crustal thickness; the dynamic contribution of an old, detached slab supposedly present within the mantle below the AAD; and depletion in ϕm, a parameter here defined as the ‘‘ubiquitously distributed melt fraction’’ within the asthenosphere. These effects may all contribute to the observed, anomalously low subsidence rate of the ridge flanks, with the most significant contribution being probably related to the depletion in ϕm. However, these effects have a deep-seated origin that cannot explain the abruptness of the transition across the fracture zones that delineate the boundaries of the AAD, near 120°E and near 128°E, respectively.
Singing queer : archiving and constructing a lineage through song.
Creators: name: Cherry-Reid, Katharine A.
Publisher: name: University of British Columbia
Year: 2016

description: Using an arts-based approach, this research examines how songs written by queer and lesbian musicians can account for and archive queer lived existence while constructing a musical genealogy for listeners and artists alike. By examining my own experience of listening to and attending performances of certain queer and lesbian identified musicians, and then composing and performing my own songs in public spaces, I make a case for the corporeal mobility of songs, and a process I have termed “queer musical lineaging.” Much of the research around music to date has centred on how it impacts and influences brain activity, and how it brings together subcultures and publics. The significance of this project lies in the research around musical processes and practices (listening, composing, performing) as corporeal acts that connect bodies to one another, and build kinships. This research draws mainly upon primary sources of autoethnographic, written accounts in the form of journal entries, stories, poems and song lyrics, and conducts an interpretive analysis of six “queer” songs, five composed by the author of this thesis, and one composed in collaboration with a trans* youth. This project will contribute to research on arts-based practices as archival work, as well as the impact that songs have on people’s lives by broadening our understanding of music’s corporeal effects and genealogical role in lived experience.

description: We present the first pilot study of jets from young stars conducted with X-shooter, on ESO/VLT. As it offers simultaneous, high quality spectra in the range 300-2500 nm X-shooter is uniquely important for spectral diagnostics in jet studies. We chose to probe the accretion/ejection mechanisms at low stellar masses examining two targets with well resolved continuous jets lying on the plane of the sky, ESO-HA 574 in Chamaleon I, and Par-Lup3-4 in Lupus III. The mass of the latter is close to the sub-stellar boundary (Mstar=0.13 Msun). A large number of emission lines probing regions of different excitation are identified, position-velocity diagrams are presented and mass outflow/accretion rates are estimated. Comparison between the two objects is striking. ESO-HA 574 is a weakly accreting star for which we estimate a mass accretion rate of log(\dot{Macc}) = -10.8 \pm 0.5 (in Msun/yr), yet it drives a powerful jet with \dot{Mout} ~ 1.5-2.7 10^-9 Msun/yr. These values can be reconciled with a magneto-centrifugal jet acceleration mechanism only assuming that the presence of the edge-on disk severely depresses the luminosity of the accretion tracers. In comparison Par-Lup3-4 with stronger mass accretion (log(\dot{Macc}) = -9.1 \pm 0.4 Msun/yr), drives a low excitation jet with about \dot{Mout} ~ 3.2 10^-10 Msun/yr in both lobes. Despite the low stellar mass, \dot{Mout} / \dot{Macc} for Par-Lup3-4 is at the upper limit of the range usually measured for young objects, but still compatible with a steady magneto-centrifugal wind scenario if all uncertainties are considered.

Multiview depth-based pose estimation
Creators: name: Shafaei, Alireza
Publisher: name: University of British Columbia
Year: 2016

description: Commonly used human motion capture systems require intrusive attachment of markers that are visually tracked with multiple cameras. In this work we present an efficient and inexpensive solution to markerless motion capture using only a few Kinect sensors. We use our system to design a smart home platform with a network of Kinects that are installed inside the house. Our first contribution is a multiview pose estimation system. Unlike the previous work on 3d pose estimation using a single depth camera, we relax constraints on the camera location and do not assume a co-operative user. We apply recent image segmentation techniques with convolutional neural networks to depth images and use curriculum learning to train our system on purely synthetic data. Our method accurately localizes body parts without requiring an explicit shape model. The body joint locations are then recovered by combining evidence from multiple views in real-time. Our second contribution is a dataset of 6 million synthetic depth frames for pose estimation from multiple cameras with varying levels of complexity to make curriculum learning possible. We show the efficacy and applicability of our data generation process through various evaluations. Our final system exceeds the state-of-the-art results on multiview pose estimation on the Berkeley MHAD dataset. Our third contribution is a scalable software platform to coordinate Kinect devices in real-time over a network. We use various compression techniques and develop software services that allow communication with multiple Kinects through TCP/IP. The flexibility of our system allows real-time orchestration of up to 10 Kinect devices over Ethernet.

description: We analyzed the full Stokes spectra using simultaneous measurements of the photospheric (FeI 630.15 and 630.25 nm) and chromospheric (MgI b2 517.27 nm) lines. The data were obtained with the HAO/NSO Advanced Stokes Polarimeter, about a near disc center sunspot region, NOAA AR 9661. We compare the characteristics of Stokes profiles in terms of Doppler shifts and asymmetries among the three spectral lines, which helps us to better understand the chromospheric lines and the magnetic and flow fields in different magnetic regions. The main results are: (1) For penumbral area observed by the photospheric FeI lines, Doppler velocities derived from Stokes I (Vi) are very close to those derived from linear polarization profiles (Vlp) but significantly different from those derived from Stokes V profiles (Vzc), which provides direct and strong evidence that the penumbral Evershed flows are magnetized and mainly carried by the horizontal magnetic component. (2) The rudimentary inverse Evershed effect observed by the MgI b2 line provides a qualitative evidence on its formation height that is around or just above the temperature minimum region. (3) Vzc and Vlp in penumbrae and Vzc in pores generally approach their Vi observed by the chromospheric MgI line, which is not the case for the photospheric FeI lines. (4) Outer penumbrae and pores show similar behavior of the Stokes V asymmetries that tend to change from positive values in the photosphere (FeI lines) to negative values in the low chromosphere (MgI line). (5) The Stokes V profiles in plage regions are highly asymmetric in the photosphere and more symmetric in the low chromosphere. (6) Strong red shifts and large asymmetries are found around the magnetic polarity inversion line within the common penumbra of the Delta spot. This study thus emphasizes the importance of spectro-polarimetry using chromospheric lines.

description: Este artigo pretende analisar, a partir dos pergaminhos existentes no Arquivo Distrital de Braga, a relação existente entre os arcebispos e a instituição capitular bracarense, num tempo de transição entre os séculos XIII e XIV, em que foram titulares da cadeira arquiepiscopal, sucessivamente, os arcebispos D. Telo, D. Martinho Pires de Oliveira e D. João de Soalhães. O cabido aceita e respeita a autoridade do arcebispo, mas não hesita em apelar à coroa ou à santa sé, caso se sinta lesado. O prelado promulga as constituições que regem a canónica, mas é-lhe exigido que obtenha o consenso capitular na tomada de certas decisões. As maiores controvérsias surgem, no entanto, nos momentos de preenchimento das vagas capitulares e nos períodos de sede vacante, em que se manifestam mais claramente as solidariedades e oposições existentes.

Near-axis subsidence rates, hydrothermal circulation, and thermal structure of mid-ocean ridge crests

description: We systematically investigated near-axis subsidence on the ridge flanks of intermediate and fast spreading mid-ocean ridges using bathymetric data from well-surveyed portions of the Southeast Indian Ridge (spreading at 72-76 mm/yr), the northern East Pacific Rise (91-96 mm/yr), and the southern East Pacific Rise (144 mm/yr). In all three regions, the mean subsidence rate of young (< 1 - 1.4 Ma) seafloor is less than 220 m/m.y1/2. The distribution of individual estimates shows a distinct peak at 180 - 220 m/m.y.1/2 with few profiles having subsidence rates greater than 275 m/m.y.1/2. The observed subsidence rates are significantly lower than both the worldwide average (~350 m/m.y.1/2) and subsidence rates observed for older lithosphere at the same ridge segments. Intense hydrothermal circulation at the ridge axis can result in low subsidence rates on the adjacent ridge flanks provided the vigorous flow is confined to the immediate vicinity (< ~5 km) of the axis. According to our model, the extremely vigorous hydrothermal circulation ceases off-axis, and conductive heat flow becomes a primary mechanism of vertical heat transport on the ridge flanks. The very low geothermal gradient within the cooled portion of the uppermost lithosphere retards conductive cooling, and the cooled area needs to be heated from below before a geothermal gradient can be established which permits significant heat to be conducted out of the lithosphere. As a result, subsidence in very young (~0.1 - 1 Ma) lithosphere is suppressed. A simple one-dimensional thermal model with a Nusselt number parameterization was used to estimate the effect of hydrothermal circulation. An upper layer with a high Nusselt number and the half-space that it overlies are initially at a temperature of 1300°C and the surface is maintained at 0°C. After 0.1 m.y. of cooling (about 3.5 to 7 km from the spreading axis), the Nusselt number of the top layer is set to 1 so that normal conduction is simulated in the cooled layer. We used an explicit finite difference method to solve for the temporal changes in temperature with depth. This model produces subsidence rates in the range that we observe for Nu in the range of 15-30. Isotherms resulting from the modeling imply rapid lithospheric thickening very near the axis, which is incompatible with most current models for the formation of the bathymetric axial high observed at fast spreading mid-ocean ridges.

description: É objectivo deste artigo a apresentação de uma síntese sobre a reciprocidade da relação eciesiásticos-leigos, convivendo próxima e assiduamente, na cidade de Braga, durante a Baixa IdadeMédia. Por um lado, sublinhando a importância da origem geográfica e social dos cónegos, para melhor conhecermos o maior ou menor grau do seu enraizamento na cidade, procurámos descrever as diferentes formas de relacionamento entre estes e a sociedade local. Que contornos tomavam as suas atitudes e comportamentos, face a um trato diário, por inevitável, desejado ou não? Que pressões ou influências mútuas é possível distinguir nos testemunhos que a história desta cidade, intencionalmente ou não, nos legou? São estas as questões fundamentais a que tentamos dar resposta. Por outro lado, ao longo da análise das relações entre ambas as partes, é possível concluir o elevado estatuto social da canónica bracarense baseado, para além dos laços de sangue, no seu considerável poder económico e cultural.

description: Nahezu alle überlieferten Werke der Kunst wurden im Laufe ihrer Geschichte auf verschiedene Weise und mit unterschiedlichen Folgen zu Fragmenten. Die heutige Unvollständigkeit dieser Wer-ke mit den daraus resultierenden historischen und ästhetischen Eigenschaften wird jedoch nur selten erkannt und als solche bezeichnet. Diese Leitlinien zielen auf unseren Umgang mit Fragmenten. Wie sind diese am besten zu verste-hen und zu präsentieren? Sind hierfür Ergänzungen notwendig, und wenn ja, in welcher Form? Die Entwicklung und der Zuwachs an Bedeutung digitaler Techniken in der Konservierung-Restaurierung und in der Vermittlung von fragmentarischem Kunst- und Kulturgut erfordern eine Aktualisierung bisheriger Grundsätze. Diese Leitlinien möchten dazu beitragen, Chancen und Risiken zu erkennen, um die digitalen Mittel zum Wohle der originalen Fragmente einzusetzen.

dd-PyClone : improving clonal subpopulation inference from single cells and bulk sequencing data
Creators: name: Salehi, Sohrab

description: Improving our understanding of intra-tumour heterogeneity in cancer has important clinical implications, including an opportunity to understand mechanisms behind relapses and drug resistance. Next generation bulk sequencing is a mature tech- nology that has been used to study subclonal tumour populations at an aggregate level. Inference of populations from bulk sequencing requires sophisticated com- putational deconvolution methods. An alternative is to identify populations directly with single cell sequencing. However, single cell sequencing is a very error-prone process, and this impedes its ability to completely replace bulk sequencing for now. In this work we present dd-PyClone, a statistical model to combine single cell and bulk sequencing data to study clonal subpopulation architecture and improve clustering assignment and cellular prevalence estimates of a set of genomic loci. We introduce a single nucleotide variant and copy number aberration aware genotype simulation scheme based on a phylogenetic tree, termed the Generalized Dollo model. This model is an improvement over previous genotype generator models in that it also accounts for the evolutionary process before a rare event (here the single nucleotide variant) occurs. We show that incorporating genomic loci co-occurrence patterns from single cell sequencing studies in inferring clonal subpopulation structure from bulk se- quencing data is beneficial. Our method outperforms existing methods in simula- tion studies and performs comparably in real dataset benchmarking. We also show that our method is fairly robust as to the choice of hyperparameters and performs reasonably in presence of noise. We hope that our method will further the under- standing of the evolutionary basis of cancer.
