Unified mathematical treatment of complex cascaded bipartite networks: The case of collections of journal papers
No full textIn this study, a mathematical treatment is proposed for analysis of entities and relations among entities in
complex networks consisting of cascaded bipartite networks. This treatment is applied to the case of
collections of journal papers. In this case, entities are distinguishable objects and concepts, such as papers,
references, paper authors, reference authors, paper journals, reference journals, institutions, terms, and term
definitions. Relations are associations between entity-types such as papers and the references they cite, or
paper authors and the papers they write. An entity-relationship model is introduced that explicitly shows
direct links between entity-types and possible useful indirect relations. From this a matrix formulation and
generalized matrix arithmetic are introduced that allow easy expression of relations between entities and
calculation of weights of indirect links and co-occurrence links. Occurrence matrices, equivalence
matrices, membership matrices and co-occurrence matrices are described. A dynamic model of growth
describes recursive relations in occurrence and co-occurrence matrices as papers are added to the paper
collection. Graph theoretic matrices are introduced to allow information flow studies of networks of papers
linked by their citations. Similarity calculations and similarity fusion are explained. Derivation of feature
vectors for pattern recognition techniques is presented. The relation of the proposed mathematical
treatment to seriation, clustering, multidimensional scaling, and visualization techniques is discussed. It is
shown that most existing bibliometric analysis techniques for dealing with collections of journal papers are
easily expressed in terms of the proposed mathematical treatment: co-citation analysis, bibliographic
coupling analysis, author co-citation analysis, journal co-citation analysis, Braam-Moed-vanRaan (BMV)
co-citation/co-word analysis, latent semantic analysis, hubs and authorities, and multidimensional scaling.
This report discusses an extensive software toolkit that was developed for this research for analyzing and
visualizing entities and links in a collection of journal papers. Additionally, an extensive case study is
presented, analyzing and visualizing 60 years of anthrax research through a collection of journal papers.
When dealing with complex networks that consist of cascaded bipartite networks, the treatment presented
here provides a general mathematical framework for all aspects of analysis of static network structure and
network dynamic growth. As such, it provides a basic paradigm for thinking about and modeling such
networks: computing direct and indirect links, expressing and analyzing statistical distributions of network
characteristics, describing network growth, deriving feature vectors, clustering, and visualizing network
structure and growth
Corolla size and temporal displacement of flowering times among sympatric diploid and tetraploid highbush blueberry (Vaccinium corymbosum)
No full textPolyploidy (whole-genome duplication) is common in vascular plants, but the modes of establishment and persistence, as well as the ecological consequences, of polyploidy remain vague. Highbush blueberry (Vaccinium corymbosum L.) is an ecologically and economically important understory shrub with an unclear species definition, coexisting in sympatric populations of diploid and tetraploid cytotypes. This study analyzes differences in bloom time between sympatric diploid and tetraploid V. corymbosum in natural populations, testing the potential for these cytotypes to interbreed and contributing to the formation and continuity of ploidy-level diversification within this species. Ploidal level was confirmed through DNA flow cytometry of sympatric plants from two populations in New Jersey, USA. Flower bloom date and corolla size were recorded over a three-year period. Diploid corollas were 32% smaller than tetraploid corollas, making them easily identifiable in the field. Ploidy accounted for 55-69% of the variation in bloom date, with diploids flowering about one week before tetraploids, and the remaining variation distributed among plants, among branches, and within branches. Notwithstanding these differences, there was modest overlap in flowering time between cytotypes, suggesting that cross-pollination is possible. This contributes evidence to the most current species definition of V. corymbosum as a single (mixed ploidy) species.Poster's Graduate Student Thesis Publication.Peer reviewed

Perspectives on Identity, Migration, and Displacement
No full textPerspectives on Identity, Migration, and Displacement -- edited by Steven Tötösy de Zepetnek, I-Chun Wang, and Hsiao-Yu Sun (Kaohsiung: National Sun Yat-sen University Press, 2010. ISBN 9789860235418 209 pages, bibliography, index) is a collection of articles about sociological and literary aspects of identity formation as a consequence of (im)migration. (Im)migration results in the problematics of assimilation and hybridity and in postcolonial scholarship, in particular, attention is paid to the concept of migration termed Creolization on the ground that cultural contact, cultural transmission, and cultural transformation result in the creation of new cultures.

No full textCílem této studie je navrhnout změny v marketingovém mixu vrtáků do dlaždic Společnosti X, které by měly pozitivní dopad na tržby produktu. K dosažení tohoto cíle byla provedena kombinace analýzy interních a externích sekundárních dat a kvalitativní analýzy ve formě částečně strukturovaných rozhovorů a techniky odborného posouzení. Kvalitativní část výzkumu byla provedena s regionálními produktovými manažery Společnosti X, kteří jsou považováni za odborníky na dané téma výzkumu. Na základě poznatků z výzkumu autor navrhuje prodloužit délku portfolia vrtáků do dlaždic o šest dalších průměrů a zahrnout další příslušenství, jako je adaptér a startovací sada s odsávačem prachu, který by vytvořil kompletní systém pro snadné a pohodlné vrtání do dlaždic. V rámci stanovení cen autor navrhl, aby současný cenový model byl aplikován i na nové části portfolia, protože byl určen jako přiměřený. Dále bylo navrženo zaměřit se na řetězec podnikových prodejen Společnosti X a vnitřní prodejní síly jako na primární prodejní kanály z důvodu získaní pozornosti pro daný produkt. Aby byla zajištěna efektivita propagační kampaně, bylo navrženo společné uvedení na trh s doplňkovým přístrojem a ikonickým kufříkem Společnosti X. Veškeré výsledky studie jsou podrobně popsány v závěrech této práce.The objective of this study is to propose changes within marketing mix of tile drill bits of Company X that would have a positive impact on product's revenues. To reach this goal a combination of analysis of internal and external secondary and qualitative analysis in a form of semi-structured interviews and expert judgement technique were conducted. The qualitative part of the research was executed with Company's X HUB product managers, who are considered to be experts on a given research topic. Based on the research author proposed to extend the length of tile drill bits portfolio with six additional diameters and to include additional accessories such as an adapter and starter kit with a dust collector that would create a full system for easy and convenient drilling into tiles. Within pricing author suggested to apply current pricing model also on the new parts of the portfolio since it was identified as adequate. Additionally, focus on Company’s X chain of stores and internal sales force as primary sales channels was recommended in order to create attention towards the product. In order to ensure the effectiveness of the promotional campaign, combined launch with complementary tool and the iconic Company’s X case for starter kit was proposed. All the outcomes of the study are detailly described in conclusions part of this thesis
Investigating the mechanism of FOXG1 in glioblastoma stem cells
No full textGlioblastoma multiforme (GBM) is the most common and aggressive primary brain cancer in adults. Relapse after conventional surgery and chemo/radiotherapy is thought to be driven by glioblastoma stem cells (GSCs).
GSCs have phenotypic sumularities to normal neural stem cells (NSCs) and frequently overexpress many key neurodevelopmental transcription factors, including FOXG1, a key forebrain transcription factor with reporgramming activity. Evidence points to an important funtional role of FOXG1 in driving the NSC-like identity of GSCs. Here we explore the mechanisms by which FOXG1 acts, by characterising its key downstream transcritional targets and protein-protein interactions. Analysis of the transcriptional changes induced by FOXG1 overexpression identified key targets, including cell cycle and epigenetic regulators, such as Fox06 and Chd3. Fox06 was identified as a clear downstream target with a functional role in enabling FOXG1 to drive exit from quiescence. This also revealed the FOXG1, a transcriptional repressor, can lead to gene activation. The H3K4 demethylase JARID1B (KDM5B/PLU-1), a negative regulator of promoter activation, is thought to be a protein partner of FOXG1. We hypothesised that FOXG1 may activate gene expression by sequestration of this repressor. However, our studies suggest JARID1B is not essential for FOXG1's ability to drive a proliferative NS cell-like state, nor transcriptional activiation of Fox06 or Chd3. FOXG1 immunoprecipitation studies highlighted difficulties in obtaining good quality, protein-specific antibodies for characterising protein partners. we therefore exploited CRISPR/Cas9 technology to epitope-tag endogenous FOXG1 in patient-derived glioblastoma NS (GNS) cells. These cellular models can now be used in future studies to define FOXG1's key protein partners and aid the identification of ways to therapeutically target FOXG1 in GBM

Pronotum (Fig. 83) provided with a very fine puncture; usually slightly transverse, and sub-cordiform, sometimes subcircular or sub-elliptical and more transverse, with the base straight or sub-straight, not sinuous before the posterior angles and generally something narrower than the apex. Elongated and medially depressed prosternal apophysis (Fig. 119), surpassing the level of the procoxae. Elytra oval elongated, variable in length, subcylindrical, sometimes slightly striated and somewhat broader than the pronotum. Small aedeagus, fusiform parameres and barely longer than phallobase (Fig. 167).</p> <p> <b>Comments</b>: Species described from “Lusitania”, not from Andalusia as Viñolas & Catagena (2005) mentioned. Steven (1828) described <i>Tentyria platyceps</i> with at least one specimen from “Lusitania” (MNHUB). Data on the Steven’s description agrees with the label that carries one of the syntypes listed as <i>T. curculionoides</i> Herbst in the Berlin Museum, before to be rectified and attributed to “ <i>T. curculioides</i> Ht. *” (Fig. 231). This confusion is the reason of that the type of <i>T. platyceps</i> Steven has remained hidden to date, not appearing in the recording book of the Museum.</p> <p> Accordingly, <i>T. platyceps</i> Steven was an unknown species to Solier (1835) and Rosenhauer (1856). Hence these authors described <i>T. goudoti</i> Solier (Fig. 232) and <i>T. modesta</i> Rosenhauer (Fig. 233), with identical characters those of <i>T. platyceps</i> Steven, as indicated Kraatz (1865) and Schaum (1862) respectively. This verifies that these last authors knew the true identity of <i>T. platyceps</i> Steven, by intuiting the confusion between <i>T. curta</i> Steven and <i>T. curculionoides</i> Herbst (Kraatz 1865). From Kraatz (1865), <i>T. platyceps</i> Steven has been a species correctly interpreted by almost all authors.</p> <p> Reitter (1900), described <i>T. calcarata</i> from Malaga, which was, dubiously, considered synonymy of <i>T. platyceps</i> Steven by Español (1960), since it was the unique species of <i>Tentyria</i> present in the mentioned locality whose description fits to that Reitter gave, even when this author does not include it in the group 3, close to <i>T. platyceps</i> Steven.</p> <p> Later, Kaszab designated in litt. “ Holotypus ” of <i>T. calcarata</i> Reitter a specimen from the MNHN labelled from Malaga (Fig. 234), and which corresponds to a variant specimen of the <i>T. platyceps</i> Steven (with the pronotum very transverse, and sub-elliptical), like the syntypes of <i>Tentyria platyceps</i> v. <i>modesta</i> Rosenhauer.</p> <p> <b> Designation of the Lectotype <i>Tentyria platyceps</i> Steven, 1828, present designation</b> :</p> <p> The specimen of the typical series that bears the following labels (two of them old): small rectangular label, “45574” / big square label, “ <i>Orbiculata Akis</i> F., <i>curculioides</i> Ht. *, <i>Ten.

The specimen that bears the following labels: “ <i>T. platyceps</i> v. <i>modesta</i> Rosh. Hispania / <i>T. platyceps</i> v. <i>modesta</i> Rosh. / Hispania Rosh.”, is designated Lectotype (Fig. 233); the other that carrying the label: “Hispania Rosh.”, is designated Paralectotype.</p> <p> <b>Geographical distribution:</b> Widely distributed in central and southern Iberian Peninsula, especially in the inner areas. <i>T. platyceps</i> Steven, has been also cited in the north of Morocco (Tánger) as <i>T. goudoti</i> Solier (1835), Escalera (1914) and Kocher (1958).

Provenance-based trust for grid computing: Position Paper
No full textCurrent evolutions of Internet technology such as Web Services, ebXML, peer-to-peer and Grid computing all point to the development of large-scale open networks of diverse computing systems interacting with one another to perform tasks. Grid systems (and Web Services) are exemplary in this respect and are perhaps some of the first large-scale open computing systems to see widespread use - making them an important testing ground for problems in trust management which are likely to arise. From this perspective, today's grid architectures suffer from limitations, such as lack of a mechanism to trace results and lack of infrastructure to build up trust networks. These are important concerns in open grids, in which "community resources" are owned and managed by multiple stakeholders, and are dynamically organised in virtual organisations. Provenance enables users to trace how a particular result has been arrived at by identifying the individual services and the aggregation of services that produced such a particular output. Against this background, we present a research agenda to design, conceive and implement an industrial-strength open provenance architecture for grid systems. We motivate its use with three complex grid applications, namely aerospace engineering, organ transplant management and bioinformatics. Industrial-strength provenance support includes a scalable and secure architecture, an open proposal for standardising the protocols and data structures, a set of tools for configuring and using the provenance architecture, an open source reference implementation, and a deployment and validation in industrial context. The provision of such facilities will enrich grid capabilities by including new functionalities required for solving complex problems such as provenance data to provide complete audit trails of process execution and third-party analysis and auditing. As a result, we anticipate that a larger uptake of grid technology is likely to occur, since unprecedented possibilities will be offered to users and will give them a competitive edge
