Full textAbstract:
Biobased carbon materials (BBC) obtained from Norway spruce (Picea abies Karst.) bark was produced by single-step chemical activation with ZnCl2 or KOH, and pyrolysis at 800 °C for one hour. The chemical activation reagent had a significant impact on the properties of the BBCs. KOH-biobased carbon material (KOH-BBC) had a higher specific surface area (SBET), equal to 1067 m2 g−1, larger pore volume (0.558 cm3 g−1), more mesopores, and a more hydrophilic surface than ZnCl2-BBC. However, the carbon yield for KOH-BBC was 63% lower than for ZnCl2-BBC. Batch adsorption experiments were performed to evaluate the ability of the two BBCs to remove two dyes, reactive orange 16 (RO-16) and reactive blue 4 (RB-4), and treat synthetic effluents. The general order model was most suitable for modeling the adsorption kinetics of both dyes and BBCs. The equilibrium parameters at 22 °C were calculated using the Liu model. Upon adsorption of RO-16, Qmax was 90.1 mg g−1 for ZnCl2-BBC and 354.8 mg g−1 for KOH-BBC. With RB-4, Qmax was 332.9 mg g−1 for ZnCl2-BBC and 582.5 mg g−1 for KOH-BBC. Based on characterization and experimental data, it was suggested that electrostatic interactions and hydrogen bonds between BBCs and RO-16 and RB-4 dyes played the most crucial role in the adsorption process. The biobased carbon materials showed high efficiency for removing RO-16 and RB-4, comparable to the best examples from the literature. Additionally, both the KOH- and ZnCl2-BBC showed a high ability to purify two synthetic effluents, but the KOH-BBC was superior.

Full textAbstract:
AbstractThis article presents research on two key BBC World Service websites, BBC Persian Online and BBC Arabic Online. It draws on in-house BBC data, supplemented by our own semi-structured interviews with online editors and other key World Service staff. It examines where users of the two sites are located, their demographic characteristics and their views on and uses of the sites. The data is analyzed in the context of debates about the politics of diasporic media and communication networks and changing collective identities, the UK government's Foreign and Commonwealth Office's (FCO) strategy of 'digital diplomacy' and the World Service's stated public purpose of fostering a 'global conversation.' Our research has shown how the majority of users of both BBC Arabic and Persian Online services reside outside the geographical areas that the BBC World Service targets and may be defined as diasporic. And these two websites are not exceptional. Diasporic groups make increasing use of the BBC's online foreign language news sites but these transnational communication networks are an unintended consequence of the BBC's activities. We highlight how the internet is changing configurations of audiences and users at the BBC World Service as geographically dispersed language groups can log on to the news services from anywhere in the world. We argue that the BBC World Service can no longer be seen as an international broadcaster pursuing the BBC's motto 'nation shall speak peace unto nation.' Rather, as one of the world's largest news providers, it is implicated in the formation of new kinds of transnational communities and communications which has as yet unforeseen consequences for national identifications and for strategies of public diplomacy.

Purpose: To investigate the association between the bird-beak configuration (BBC), a wedge-shaped gap between the undersurface of a thoracic endograft and the lesser curvature of the arch after thoracic endovascular aortic repair (TEVAR), and postoperative outcome after TEVAR. Methods: The study was performed according to the PRISMA guidelines. The PubMed, EMBASE, and Cochrane databases were searched to identify all case series reporting BBC after TEVAR between 2006 and April 2018. Data analysis was performed considering the difference in the risk of complications for presence vs absence of BBC. After screening 1633 articles, 21 studies were identified that matched the selection criteria; 12 of these reported detailed information to investigate the postoperative outcome using proportion meta-analysis with a random effects model. The pooled risk difference is reported with the 95% confidence interval (CI). Heterogeneity of the included studies was assessed with the I2 statistic (low 25%, medium 50%, high 75%). Results: Complications occurred within a range of 0 to 72 months in 14.7% (95% CI 7.4% to 27.3%) of patients with BBC and in 6.3% (95% CI 2.5% to 15.4%) of patients without BBC. A cumulative incidence could not be assessed. The summary risk difference was 11.1% (95% CI −0.1% to 22.3%, p=0.052). There was significant heterogeneity ( I2=85.6%). The Egger test did not show evidence of publication bias (p=0.975). When specifically considering type Ia endoleak and endograft migration, the risk difference between BBC and non-BBC patients was 8.2% (95% CI 0.3% to 16.1%, p=0.042; I2=69.0%). The specific risk difference for endograft collapse/infolding and thrombosis was 3.7% (95% CI −3.5% to 11.1%, p=0.308; I2=10.2%). Conclusion: At present the literature does not provide statistical evidence to establish an overall prognostic value of the BBC. Nevertheless, the BBC appears to be associated with a high risk of type Ia endoleak and endograft migration, which warrants specific and long-term surveillance. Clinically relevant values for BBC grading should be established to perhaps define indications for preemptive treatment based on the presence of BBC only.

This research attempts to reveal representation of Kim Jong-Un’s succession in BBC News through textual and discursive practice analysis. The data of this thesis are taken from BBC News website on 29 and 31 December 2011. The theory applied to seek the objective of the research is Critical Discourse Analysis developed by Fairclough. Through textual and discursive practice analysis, the writer finds pthat BBC employs more passive material clauses than active material clauses in depicting Kim Jong-Un’s succession. BBC also represents Kim Jong-Un’s succession as premature process where Kim Jong-Un is portrayed as a young and inexperienced leader. Besides the prematurity of the succession, the present writer finds that BBC represents Kim Jong-Un’s succession as continuity of Kim’s family dynasty. Thus, the succession is based on his resemblance to Kim Il-Sung, the founder of Democratic People’s Republic of Korea, rather than Kim Jong-Un ability and competency.

Full textAbstract:
The present study investigates the influence of co-administration of different concentrations (2, 6, and 10 mg) of curcumin on goat intestinal permeability of berberine chloride (BBC) using Franz diffusion cell. Data obtained in triplicate from permeability studies were used to calculate percentage cumulative drug release (% CDR), apparent permeability (Papp), flux (J) and enhancement ratio (ER). Co-administration of 6 mg concentration of curcumin with BBC was found to be optimum to enhance the permeability of BBC up to 23.92 ± 0.78 % CDR, over control (8.49 ± 1.45 % CDR). At the optimized concentration of curcumin, permeability characteristics were improved significantly compared to control. The present study reveals the beneficial effect of co-administration of curcumin (6 mg) to promote membrane permeability of BBC which would be expected to improve its bioavailability, thereby therapeutic efficacy. The effect could be attributed to curcumin-mediated inhibition of intestinal efflux pump P-gp, acting as an absorption barrier for BBC.

Full textAbstract:
Among the technologies that have modified the digital journalism since its inception,
there are two that can be highlighted: 1) the World Wide Web (Web), a network of digital
documents that has being used as a platform to the practice of journalism on the Internet and
that determined the three generations of digital journalism; and 2) the databases aggregate to
the Web, that have become the main technology behind the structuring of journalistic
products in the transition between the third and fourth generation of digital journalism. In
2001, the scientist Tim Berners-Lee, inventor of the web, published a paper with a proposal of
an extension to this network, which was called the Semantic Web. The paper proposed a
change in the concept of the current web: from the traditional network made of documents to
a network made of data, plus the technical ability to represent real concepts, such as people,
places and objects. A great advantage of this proposal is that computers would be able to
understand the data and identify their meanings. With a semantic network, the information
could be organized and managed more efficiently and in an automated way, and the
connections between the data would be richer than the current hyperlinks between documents.
The concept of the Semantic Web is still maturing, but it is currently possible to find digital
products that implement this concept. This research aims to analyze two real cases that apply
the concept of the Semantic Web in digital journalism, specifically in the organization and
management of the newspaper reports. For the theoretical background of research, we
conducted a literature review on digital journalism, paradigm of the Digital Journalism on
Databases (JDBD) and how the standard technologies of the Semantic Web work, such as
RDF and ontologies. This is an exploratory research and it uses the case study as a method.
The cases are the site 'World Cup 2010 BBC' and the site 'BBC Wildlife'. The analysis was
performed using eight categories applicable to the study of JDBD. Among the results, it is
found that the Semantic Web improve some of the characteristics of JDBD, mainly due to the
automation on management tasks. Moreover, it identified that automated interoperability was
the more advantageous benefit of Semantic Web to both digital journalism cases, and that it
can become a potential rupture if the Semantic Web project come to succeed.<br>Entre as tecnologias que transformaram o jornalismo digital desde o seu surgimento,
destacam-se duas: a World Wide Web (web), rede de documentos digitais que serviu como
plataforma à prática jornalística na internet e determinou as três fases evolutivas do
jornalismo digital; e as bases de dados, que, agregadas à web, se tornaram a principal
tecnologia estruturante dos produtos jornalísticos na fase de transição entre a terceira e a
quarta geração do jornalismo digital. No ano de 2001, o cientista Tim Berners-Lee, inventor
da web, publicou um artigo com a proposta de uma expansão para esta rede, a qual foi
denominada Web Semântica. O artigo propunha uma mudança no conceito da web: da
tradicional rede de documentos para uma rede de dados, com capacidade para representar
conceitos reais, como pessoas, lugares e objetos. Um grande diferencial desta proposta é que
os computadores teriam capacidade para interpretar tais dados e identificar seus significados.
Em uma rede semântica, as informações poderiam ser organizadas e gerenciadas de forma
mais eficiente e automatizada, e as conexões entre dados seriam mais ricas do que através dos
atuais links entre documentos. O conceito de Web Semântica ainda está em fase de
amadurecimento, mas já é possível encontrar em funcionamento produtos digitais que aplicam
tal conceito. A proposta desta pesquisa é analisar dois casos que aplicam o conceito da Web
Semântica no jornalismo digital, mais especificamente na organização e no gerenciamento das
informações jornalísticas. Para o embasamento teórico da investigação, foi realizada uma
revisão bibliográfica sobre o jornalismo digital, sobre o paradigma do Jornalismo Digital em
Base de Dados (JDBD) e sobre o funcionamento das tecnologias empregadas na Web
Semântica, tais como o RDF e as ontologias. A pesquisa apresenta caráter exploratório e
emprega como estratégia de investigação o estudo de caso, especificamente dos sites BBC
World Cup 2010 e BBC Wildlife. A análise foi realizada a partir de oito categorias aplicáveis
ao estudo do JDBD. Entre os resultados, é constatado que a Web Semântica potencializa
algumas das características do JDBD, principalmente devido à automatização. Além disso, foi
identificado nos casos estudados que a interoperabilidade automatizada foi o benefício mais
vantajoso da Web Semântica em relação às tecnologias até então utilizadas no jornalismo
digital, e que pode se tornar uma ruptura caso o projeto de Web Semântica obtenha êxito.

Full textAbstract:
This research consists of two parts. The first part examines the posterior probability integrals for a family of linear models which arises from the work of Hart, Koen and Lombard (2003). Applying Laplace's method to these integrals is not entirely straightforward. One of the requirements is to analyze the asymptotic behavior of the information matrices as the sample size tends to infinity. This requires a number of analytic tricks, including viewing our covariance matrices as tending to differential operators. The use of differential operators and their Green's functions can provide a convenient and systematic method to asymptotically invert the covariance matrices. Once we have found the asymptotic behavior of the information matrices, we will see that in most cases BIC provides a reasonable approximation to the log of the posterior probability and Laplace's method gives more terms in the expansion and hence provides a slightly better approximation. In other cases, a number of pathologies will arise. We will see that in one case, BIC does not provide an asymptotically consistent estimate of the posterior probability; however, the more general Laplace's method will provide such an estimate. In another case, we will see that a naive application of Laplace's method will give a misleading answer and Laplace's method must be adapted to give the correct answer. The second part uses numerical methods to compute the "exact" posterior probabilities and compare them to the approximations arising from BIC and Laplace's method.

Measuring Biodiversity is an important phenomenon to serve best to our ecology and also keep environment sound. Variety of life on different levels, like an ecosystem, life forms on a site, landscape collectively known as Biodiversity. Species richness and evenness combine measures as Biodiversity. Separate formula, index, equation are widely using to measure Biodiversity in each level. Swedish Environmental Protection Agency aimed to establish an index that consists of landscape functionality and landscape heterogeneity. For landscape functionality assessment, there BBCI (Biotope biodiversity Capacity index) is going to use. High BBCI indicates a high biodiversity for each biotope. However, empirically estimate species richness how much matched with BBCI that not been evaluated. The aim of this paper to see the relationship between empirical estimated Biodiversity and BBCI. A relationship between Shannon diversity index and BBCI also ran to see the matches between them. Collect the empirical data from selected 15 landscapes using Artportalen.se and sort the data for further calculation. Results showed that there was a strong positive relationship between empirical estimated Biodiversity and BBCI. Again Shannon diversity index and BBCI also demonstrated a positive correlation between them. It showed BBCI could explain 60%-69% of species richness data and 17%-22% of Shannon diversity index. It indicates the acceptance of theoretical study of measure Biodiversity.

Full textAbstract:
A remarkable gap exists between the financial impact of fraud in the B2C e-commerce mail order business and the amount of research conducted in this area — whether it be qualitative or quantitative research about fraud prevention. Projecting published fraud rates of only approx. one percent to e-commerce sales data, the affected sales volume amounts to $651 million in the German market, and in the North American market, the volume amounts to $5.22 billion; empirical data, however, indicate even higher fraud rates. Low profit margins amplify the financial damage caused by fraudulent activities. Hence, companies show increasing concern for raising numbers of internet fraud. The problem motivates companies to invest into data analytics and, as a more sophisticated approach, into automated machine learning systems in order to inspect and evaluate the high volume of transactions in which potential fraud cases can be buried. In other areas that face fraud (e.g. automobile insurance), machine learning has been applied successfully. However, there is little evidence yet about which variables may act as fraud risk indicators and how to design such systems in the e-commerce mail order business. In this research, mixed methods are applied in order to investigate the question how computer-aided systems can help detect and prevent fraudulent transactions. In the qualitative part, experts from fraud prevention companies are interviewed in order to understand how fraud prevention has been conventionally conducted in the e-commerce mail order business. The quantitative part, for which a dataset containing transactions from one of the largest e-commerce firms in Europe has been analyzed, consists of three analytical components: First, feature importance is evaluated by computing information gain and training a decision tree in order to find out which features are relevant fraud indicators. Second, a prediction model is built using logistic regression and gradient boosted trees. The prediction model allows to estimate the fraud risk of future transactions. Third, because risk estimation alone does not equal profit maximization, utility theory is woven into prioritization of transactions such that the model optimizes the financial value of fraud prevention activities. Results indicate that the interviewed companies want to use intelligent computer-aided systems that support manual inspection activities through the use of data mining techniques. Feature analysis reveals that some features, such as whether a shipment has been sent to a parcel shop, can help separate fraudulent from legitimate orders better than others. The predictive model yields promising results as it is able to correctly identify approximately 86% of the 2% most suspicious transactions as fraud. When the model is used to optimize the financial outcome instead of pure classification quality, results suggest that the company providing the dataset could achieve substantial additional savings of up to 87% through introduction of expected utility as a ranking measure when being constrained by limited inspection resources.

Dados composicionais são constituídos por vetores cujas componentes representam as proporções de algum montante, isto é: vetores com entradas positivas cuja soma é igual a 1. Em diversas áreas do conhecimento, o problema de estimar as partes $y_1, y_2, \\dots, y_D$ correspondentes aos setores $SE_1, SE_2, \\dots, SE_D$, de uma certa quantidade $Q$, aparece com frequência. As porcentagens $y_1, y_2, \\dots, y_D$ de intenção de votos correspondentes aos candidatos $Ca_1, Ca_2, \\dots, Ca_D$ em eleições governamentais ou as parcelas de mercado correspondentes a industrias concorrentes formam exemplos típicos. Naturalmente, é de grande interesse analisar como variam tais proporções em função de certas mudanças contextuais, por exemplo, a localização geográfica ou o tempo. Em qualquer ambiente competitivo, informações sobre esse comportamento são de grande auxílio para a elaboração das estratégias dos concorrentes. Neste trabalho, apresentamos e discutimos algumas abordagens propostas na literatura para regressão sobre dados composicionais, assim como alguns métodos de seleção de modelos baseados em inferência bayesiana. \\\\<br>Compositional data consist of vectors whose components are the proportions of some whole.

The percentages $y_1, y_2, \\dots, y_D$ of votes corresponding to the competitors $Ca_1, Ca_2, \\dots, Ca_D$ in governmental elections or market share problems are typical examples. Of course, it is of great interest to study the behavior of such proportions according to some contextual transitions. In any competitive environmet, additional information of such behavior can be very helpful for the strategists to make proper decisions. In this work we present and discuss some approaches proposed by different authors for compositional data regression as well as some model selection methods based on bayesian inference.\\\\

Full textAbstract:
Philosophiae Doctor - PhD<br>The Platreef is a platinum group elements (PGE) deposit located in the Northern limb of the Bushveld Igneous Complex (BIC). It is a series of mafic and ultramafic sills that are overlain by rocks from the Main Zone (MZ) of the BIC. In comparison to PGE deposits (i.e., Merensky Reef and the UG-2 chromitite) occurring in the Critical Zone (CZ) of the Eastern and Western Limbs of the BIC, which are less than 1 m in thickness, the Platreef is 10 to 400 m in thickness and is comprised of a variety of rocks. PGE mineralisation in the Platreef is not confined to a specific rock type, and its distribution and styles also vary with depth and along strike. Despite the numerous researches that have been conducted, the genesis of Platreef is still poorly understood.
New major and trace elements in conjunction with Sr–Nd isotope data, generated from whole-rock analyses of different Platreef rocks, were collected from four drill cores along its strike. The data were examined to determine the source of the magmas and identify the processes involved in its genesis. The study also aimed at establishing whether a genetic link exists between the Platreef magmas and the magmas that formed the Lower Zone (LZ), CZ and MZ in the Rustenburg Layered Suite (RLS) of the BIC.
The petrography revealed that the Platreef in the four drill cores consists of harzburgite, olivine pyroxenite, pyroxenite, feldspathic pyroxenite and norite. Based on the textural and modal mineralogy variations, feldspathic pyroxenite was subdivided into five types (I, II, III, IV and V). The variation in the average contents of MgO, LaN/YbN and ΣREE for the Platreef rocks are consistent with the modal mineralogy from the least to the most differentiated rocks. However, the Sr–Nd isotope data of the Platreef rocks have revealed two distinct groups of samples with decreasing ɛNd2060. Group 1 consists of pyroxenite and feldspathic pyroxenite II, III and V having ɛNd2060 values that range from –8.4 to –2.9, and 87Sr/86Sr2060 values from 0.707281 to 0.712106. The Platreef rocks of group 2 consist of olivine pyroxenite and feldspathic pyroxenite Type I with ɛNd2060 ranging from –12.6 to –10.8, and 87Sr/86Sr2060 ranging from 0.707545 to 0.710042.
In comparison to the LZ, CZ and MZ rocks, which have ɛNd values ranging from –8.5 to –5.1, and 87Sr/86Sr ranging from 0.704400 to 0.709671, Platreef pyroxenite of group 1 have lower negative ɛNd2060 values (from –3.8 to –2.9) and higher 87Sr/86Sr2060 values from 0.709177 to 0.710492, whereas feldspathic pyroxenite of group 1 have overlapping ɛNd2060 values (from –8.4 to –4.9) but also higher 87Sr/86Sr2060 values (from 0.707281 to 0.712106). Instead, the Platreef olivine pyroxenite and feldspathic pyroxenite in group 2 highly negative ɛNd2060 values and overlapping 87Sr/86Sr2060 values.
It is therefore suggested that the Platreef magmas derived from the partial melting of an heterogeneous mantle source comprising depleted mantle melts and both metasomatized slightly unradiogenic Nd enriched melts and highly unradiogenic Nd enriched melts from the subcontinental lithospheric mantle. These magmas ascended via the continental crust using different paths and interacted with rocks of different Sr–Nd isotopic compositions which resulted in the formation the hybrid magmas. The study speculates that sulphide saturation in the Platreef magmas was reached in the staging chambers at depth, and the varying styles of the PGE mineralisation in the Platreef rocks are the result of the varying degree of partial melting of the heterogeneous source for their magmas.
In conlusion, this study suggests that the genesis of the Platreef is much more complex and should be considered very much independent from processes involved in the genesis of the RLS in the Eastern and Western Limbs of BIC in agreement with earlier studies.<br>NRF

Full textAbstract:
En vue d’aider les opérateurs mobiles avec la gestion de leurs réseaux d’accès radio, trois modèles sont proposés. Le premier modèle est une approche supervisée pour une prévention des anomalies. Son objectif est de détecter les dysfonctionnements futurs d’un ensemble de cellules en observant les indicateurs clés de performance considérés comme des données fonctionnelles. Par conséquent, en alertant les ingénieurs et les réseaux auto-organisés, les opérateurs mobiles peuvent être sauvés d’une dégradation de performance de leurs réseaux. Le modèle a prouvé son efficacité avec une application sur données réelles qui vise à détecter la dégradation de capacité, les problèmes d’accessibilités et les coupures d’appel dans des réseaux LTE.A cause de la diversité des technologies mobiles, le volume de données qui doivent être quotidiennement observées par les opérateurs mobiles devient énorme. Ce grand volume a devenu un obstacle pour la gestion des réseaux mobiles. Le second modèle vise à fournir une représentation simplifiée des indicateurs clés de performance pour une analyse plus facile. Du coup, un modèle de classification croisée pour données fonctionnelles est proposé. L’algorithme est basé sur un modèle de blocs latents dont chaque courbe est identifiée par ses composantes principales fonctionnelles. Ces dernières sont modélisées par une distribution Gaussienne dont les paramètres sont spécifiques à chaque bloc. Les paramètres sont estimés par un algorithme EM stochastique avec un échantillonnage de Gibbs. Ce modèle est le premier modèle de classification croisée pour données fonctionnelles et il a prouvé son efficacité sur des données simulées et aussi sur une application réelle qui vise à aider dans l’optimisation de la topologie des réseaux mobiles 4G.Le troisième modèle vise à résumer l’information issue des indicateurs clés de performance et aussi des alarmes réseaux. Un modèle de classification croisée des données mixtes : fonctionnelles et binaires est alors proposé. L’approche est basé sur un modèle de blocs latents et trois algorithmes sont comparés pour son inférence : EM stochastique avec un échantillonneur de Gibbs, EM de classification et EM variationnelle. Le modèle proposé est le premier algorithme de classification croisée pour données fonctionnelles et binaires. Il a prouvé son efficacité sur des données simulées et sur des données réelles extraites à partir de plusieurs réseaux mobiles 4G<br>In order to help the mobile operators with the management of their radio access networks, three models are proposed. The first model is a supervised approach for mobile anomalies prevention. Its objective is to detect future malfunctions of a set of cells, by only observing key performance indicators (KPIs) that are considered as functional data. Thus, by alerting the engineers as well as self-organizing networks, mobile operators can be saved from a certain performance degradation. The model has proven its efficiency with an application on real data that aims to detect capacity degradation, accessibility and call drops anomalies for LTE networks.Due to the diversity of mobile network technologies, the volume of data that has to be observed by mobile operators in a daily basis became enormous. This huge volume became an obstacle to mobile networks management. The second model aims to provide a simplified representation of KPIs for an easier analysis. Hence, a model-based co-clustering algorithm for functional data is proposed. The algorithm relies on the latent block model in which each curve is identified by its functional principal components that are modeled by a multivariate Gaussian distribution whose parameters are block-specific. These latter are estimated by a stochastic EM algorithm embedding a Gibbs sampling. This model is the first co-clustering approach for functional data and it has proven its efficiency on simulated data and on a real data application that helps to optimize the topology of 4G mobile networks.The third model aims to resume the information of data issued from KPIs and also alarms. A model-based co-clustering algorithm for mixed data, functional and binary, is therefore proposed. The approach relies on the latent block model, and three algorithms are compared for its inference: stochastic EM within Gibbs sampling, classification EM and variational EM. The proposed model is the first co-clustering algorithm for mixed data that deals with functional and binary features. It has proven its efficiency on simulated data and on real data extracted from live 4G mobile networks

Full textAbstract:
The crustal structure of a young (<10 My) ocean basin is imaged by two multichannel seismic
reflection lines comprising 230 km recorded over the central part of the northern Juan de Fuca plate off western Canada. The more northerly line ties previously interpreted deep seismic reflection lines across the Juan de Fuca ridge and the Cascadia subduction zone; the southern line ties with another interpreted line across the subduction zone. Both lines trend obliquely to the spreading direction. A marine refraction profile crossing the eastern end of the lines provides velocity constraints. The processing sequence applied to the data includes a prestack inside-trace mute of CMP gathers to reduce noise levels on the deep data, CMP stack, post-stack dip filtering, f-k migration and bandpass. Coherency-filtered stacks are helpful in tracing weaker reflectors. The stacked sections reveal a horizontally layered sedimentary sequence overlying a rugged and prominent basement reflector dipping slightly landward. A strong, fairly continuous reflection from the base of the crust at about 2 s two-way-time below the basement surface generally mimics the basement topography and shows the characteristic doubling and tripling of reflections seen in other similar surveys.
Although in general the crust appears acoustically transparent, weaker, discontinuous intracrustal reflectors are observed over 40 km at the eastern end of the northern line, and are interpreted to arise from the oceanic Layer 3A/3B and Layer 2/3 boundaries. The im-persistence of these reflectors is an indication of the complexity of the processes producing intracrustal reflectivity, and an indication of the lateral variability of crustal formation. Pseudofault traces of propagating rifts are crossed at three different locations on the two lines, the first MCS crossings of such structures. Crust associated with the pseudofault traces is related to both subhorizontal and dipping subcrustal events which are interpreted as zones of crustal thickening or underplating. Although the crustal thickness elsewhere on the lines varies by only about 10%, crust associated with the pseudofaults is as much as about 25% thicker
than average, suggesting that magma supply at transform-type offsets may at times be large. A small seamount discovered on the southern line may result from the excessive magma production at the ridge postulated at propagating rift zones.<br>Science, Faculty of<br>Earth, Ocean and Atmospheric Sciences, Department of<br>Graduate

conditions in Canada. Annual prevalence was found to vary between 19 % and 57 % and
likely one out of four patients experience a LBP recurrence within one year. The body of
knowledge on the prevalence of recurrent LBP is still limited. This study sought to present
a descriptive analysis on the epidemiology of recurrent LBP in a medical population. A
new methodology is also proposed to identify true cases of incident recurrent LBP. Since
10 % of LBP patients have been reported to generate 80 % of the costs, we will sought to
determine the secular trend of medical costs for the incident cohorts of 2003 to 2008.
Using the Canadian province of Quebec medical administrative physicians??? claims
database, 401 264 prevalent claims-based recurrent LBP patients were identified between
1999 to 2008 for having consulted at least three times for LBP in a period of 365 days. The
medical history of 81 329 prevalent patients in 2007 was screened for a retrospective period
of 11 years. High positive predictive values and Kappa statistics were used to determine the
optimal clearance period for capturing true incidence cases among patients with no prior
encounters for LBP. Physicians??? claims manuals were then used to apply a price for every
intervention provided to LBP incident patients in their index year and follow-up years.
We observed a decrease from 1.64 % to 1.33 % in the LBP annual prevalence between
2000 and 2007 for men. This decrease was mostly observed between 35 and 59 years of
age. Older women (??? 65 years) were 1.4 times more at risk to consult a physician for LBP
in a recurrent manner than older men. The annual incidence in 2007 of adult claims-based
recurrent LBP was 242 per 100 000 persons. Males of 18 to 34 years of age were found 1.2
times more at risk than their counterparts. Altogether, elderlies were 1.9 times more at risk
than young adults to consult in a recurrent manner for LBP. The annual incidence
decreased by 12 % between 2003 and 2007, while the direct costs increase by 1.4 %. The
median cost for consultations was highest for elder women and increasing in time.
These secondary analyses emphasize the importance to keep the watch on the elders in
regards to LBP, and to determine if the timely decrease in morbidity is related to
improvements in LBP management or to a medical accessibility issue. Also, costs will need
to be surveyed on a regular basis to limit the impact of future increases.

Full textAbstract:
The problem of characterizing brain functions such as memory, perception, and processing of stimuli has received significant attention in neuroscience literature. These experiments rely on carefully calibrated, albeit complex inputs, to record brain response to signals. A major problem in analyzing brain response to common stimuli such as audio-visual input from videos (e.g., movies) or story narration through audio books, is that observed neuronal responses are due to combinations of ``pure'' factors, many of which may be latent. In this paper, we present a novel methodological framework for deconvolving the brain's response to mixed stimuli into its constituent responses to underlying pure factors. This framework, based on archetypal analysis, is applied to the analysis of imaging data from an adult cohort watching the BBC show, Sherlock. By focusing on visual stimulus, we show strong correlation between our observed deconvolved response and third-party textual video annotations -- demonstrating the significant power of our analyses techniques. Building on these results, we show that our techniques can be used to predict neuronal responses in new subjects (how other individuals react to Sherlock), as well as to new visual content (how individuals react to other videos with known annotations). This paper reports on the first study that relates video features with neuronal responses in a rigorous algorithmic and statistical framework based on deconvolution of observed mixed imaging signals using archetypal analysis.

Alternating 10 nm thermoelectric films of N-type Si/SiGe and P-type Si/SiGe and B4C/B9C have been fabricated on various substrates, electrically joined and thermoelectric properties measured from 40°K up to 700°K. These nanoscale thermoelectric films demonstrate excellent thermoelectric power factors significantly higher than current bulk thermoelectric materials. The implications of the measured thermoelectric Seebeck coefficient data and electrical resistivity data for alternating 10 nm films that are grown to thicknesses of one to 10 microns means efficiencies of 15% at 200°C temperature differences and efficiencies of 30% at 400°C temperature differences. Utilizing Seebeck and resistivity data obtained by Hi-Z and UCSD, along with published bulk thermal conductivity data, which is conservative, unique thermoelectric module and generator concept designs for both power generation and cooling are presented over wide temperature and power ranges.
