Handel's Reception and the Rise of Music Historiography in Britain

description: Handel was the first composer to receive extensive and continuous historiographical attention. The earliest accounts of his life appear in John Mainwaring’s _Memoirs of the life of the late George Frederic Handel_ (1760), John Hawkins’s _A general history of the science and practice of music_ (1776), and Charles Burney’s _An account of the musical performances in commemoration of Handel_ (1785). Turning things around, these inaugural specimens of music historiography in Britain were specifically written to celebrate Handel’s life and achievements. Mainwaring’s biography was a commemorative volume, which also served the publicity needs of the Covent Garden oratorio series after the composer’s death. Hawkins’s _History_ mounted a conscious defense of a music tradition whose culmination was Handel. And the _Account_ of Burney presented a sanitized view of the 1784 Handel Festival as the musical apotheosis of the century. Handel was thus more than the subject of these narratives; he was a motivating factor for the rise of British music historiography. His posthumous image was recorded and manipulated in these early historical accounts, which were instruments of his canonization, positioning his life as an archetype of trial and triumph reflecting aspects of British identity.
Gap and spin texture engineering of Dirac topological states at the Cr-Bi$_2$Se$_3$ interface

description: The presence of an exchange field in topological insulators reveals novel spin related phenomena derived from the combination of topology and magnetism. In the present work we show the controlled occurrence of either metallic or gapped topological Dirac states at the interface between ultrathin Cr films and the Bi$_2$Se$_3$ surface. The opening and closing of the gap at the Dirac point is caused by the spin reorientation transitions arising in the Cr films. We find that atom thin layers of Cr adhered to Bi$_2$Se$_3$ surfaces present a magnetic ground state with ferromagnetic planes coupled antiferromagnetically. As the thickness of the Cr film increases stepwise from one to three atomic layers, the direction of the magnetization changes twice from out-of-plane to in-plane and to out-of-plane again. The out of plane magnetization drives the gap opening and the topological surface states acquire a circular meron spin structure. Therefore, the Cr spin reorientation leads to the metal/insulator transition in the Bi$_2$Se$_3$ surface and to the correlated modification of the surface state spin texture. Consequently, the thickness of the Cr film provides an effective and controllable mechanism to modify the metallic or gapped nature, as well as the spin texture of the topological Dirac states.

description: As rádios locais são, ontologicamente, meios de comunicação social de proximidade. Primeiro enquanto emissoras piratas, depois como rádios enquadradas legalmente, sempre procuraram promover a participação e a ligação com as comunidades onde se inserem. No caso português, um conjunto de constrangimentos de ordem económica e até estrutural, tem impedido em muitos casos a prossecução de tais políticas. A migração para a Internet, com as ferramentas que proporciona, pode representar um novo caminho na abertura e pluralidade discursiva. O presente artigo procura refletir sobre essa hipótese através de um estudo de caso de cinco sites de rádios locais portuguesas.

description: Strong Liberal political institutions are connected with lower levels of corruption because they incentivize transparency and fairness, how has Ukraine moved towards these goals? What should they look to focus on in the future? Europe and the US have supported Ukraine combatting corruption and reforming their governments, but a lot has changed since the Maidan Revolution in 2014. With support from the West not guaranteed, and an aggressive Russian neighbor, Ukraine’s geopolitical situation will not change on its own. In my analysis I’ve found that Ukraine is unlikely to reform under the current institutions which block any meaningful reform. My solution is to implement the diplomatic strategy of Finland during the Cold War, staying neutral and gaining peace and keeping their sovereignty. Peace is the first step to being able to achieve real reform.

description: A Internet é cada vez mais uma ferramenta de comunicação. As Organizações Não-Governamentais (ONG) como outras instituições tentam abraçar todas as oportunidades disponíveis no mundo digital. Apesar do acesso praticamente gratuito, é necessário investir algum tempo, capacidade humana, ou seja recursos humanos e por isso dinheiro, para alimentar estas fontes de informação. As redes sociais são hoje uma ferramenta fundamental e economicamente viável para motivar este contacto. Considerando a importância das dinâmicas que se criam nestes espaços online pretende-se discutir a presença das de algumas ONG nas redes sociais. Para analisarmos as dinâmicas destes espaços, decidimos nos debruçar sobre uma amostra de 64 entradas partilhadas nas páginas de Facebook de cinco ONG.

description: L’objectif de cette thèse est d’analyser la représentation de l’excès éthylique dans deux romans du vingtième siècle : Sous le volcan de Malcolm Lowry et Dévadé de Réjean Ducharme. Ce travail de nature comparative se situant à la jonction de plusieurs enjeux épistémologiques et esthétiques, nous proposons d’étudier le rapport à l’alcool à partir d’une herméneutique caractérisée par une distanciation avec les clichés associés à la figure de l’ivrogne tout en concentrant nos efforts à mettre en relief la spécificité de la représentation de l’alcool dans ces textes à différents niveaux d’interprétation. Pour ce faire, le premier chapitre nous permet de mettre en contexte les deux œuvres ainsi que de déposer les bases théoriques de notre méthode d’analyse à partir de deux phénomènes qui s’avèrent complémentaires et indissociables dans les textes à l’étude : l’excès et l’alcool. Par la suite, il sera question dans le deuxième chapitre, à partir de la notion d’anamorphose, de la problématique de la répétition et de ses modalités d’inscription dans les romans. Cet enjeu relié à la répétition permet, par le fait même, de poser plusieurs questionnements et d’interroger les rapports intertextuels à l’œuvre dans les récits ainsi que la logique de dédoublement et de dissolution de l’identité au cœur même de ces deux textes. Le troisième chapitre est l’occasion d’étudier un autre phénomène intrinsèquement relié à la représentation de l’alcool dans le tissu textuel, soit la fragmentation du texte littéraire en fonction de la réfraction engendrée par l’alcool. Nous verrons donc qu’en plus d’installer une esthétique fragmentaire d’un point de vue narratologique, le sens même des récits tend à se disloquer et parfois même à opposer différentes interprétations. L’analyse du quatrième chapitre s’attaque, quant à elle, directement aux digressions en tentant d’établir une logique textuelle à partir du rapport entre le récit et ses interstices digressifs en conséquence de l’alcool présent dans les récits. Une étude du rapport à la réalité fictionnelle ainsi que du statut de l’ivresse comme état de « voyance » dans les textes complète notre analyse de la représentation de l’alcool dans les deux romans.

For $u$, $v\in W$, it is known that the coordinate ring ${\mathbb C}[G^{u,v}]$ of the double Bruhat cell $G^{u,v}=BuB\cap B_-vB_-$ is isomorphic to an upper cluster algebra $\overline{\mathcal{A}}(\textbf{i})_{\mathbb C}$ and the generalized minors $Δ(k;\textbf{i})$ are the cluster variables of ${\mathbb C}[G^{u,v}]$[A.Berenstein, S.Fomin, A.Zelevinsky, Duke Math. J. 126 (2005), 1-52, arxiv:math.RT/0305434]. Recently, it is also shown that ${\mathbb C}[G^{u,v}]$ have structure of cluster algebra [K. R. Goodearl, M. T. Yakimov, arxiv:1602.00498 (2016)]. In the case $v=e$, we shall describe the generalized minor $Δ(k;\textbf{i})$ explicitly.

description: Existe em Portugal espaço para a emergência de uma informação audiovisual de proximidade via web? Em 2008 procurámos dar a resposta a essa questão. Para tal traçámos um retrato das webtelevisões então existentes em Portugal e os dados que recolhemos apontavam para a vontade de oferecer às populações via web o que o Estado não permitia, e não permite, que fosse oferecido via ondas hertzianas: informação audiovisual de proximidade. As webtelevisões surgiram um pouco por todo o país, mas com especial importância na zona norte e centro, assumindo-se como uma alternativa aos media tradicionais, não obstante muitos dos chamados media tradicionais de âmbito de proximidade terem assumido eles próprios projetos de webtelevisões com sítio online e grafismo próprios ou, em alguns casos, partindo para a incorporação de conteúdos audiovisuais integrados nas suas páginas oficiais. Os motivos para a aposta numa webtelevisão com capacidade de fornecer conteúdos audiovisuais de proximidade eram vários, mas, podemos afirmar, a aposta passava fundamentalmente pelo aproveitamento de mais um recurso comunicativo, fruto das inovações tecnológicas e da diminuição dos custos dos materiais. Dar a possibilidade ao público de aceder a outros conteúdos foi também uma das motivações para o lançamento destes projetos.

The results are similar to those of Laurent and Nogueira for $\mathrm{SL}_2 ( \mathbb{Z} )$ action on $\mathbb{R}^2 \setminus \{ \mathbf{0} \}$ albeit for us, uniformly nice bounds are obtained only outside of a set of null measure.

description: Los planteamientos de programación de las televisiones generalistas van destinados a un público masivo e indiferenciado, tratando de conseguir el mayor número de espectadores en todo momento. Organizando las parrillas de programación en función del público existente en cada franja horaria, dejando de lado a las minorías, pero este modelo ha dejado paso a la televisión especializada o televisión temática, donde las audiencias se individualizan. El proceso ha sido lento en nuestro país, aunque desde 1997 el panorama ha cambiado sustancialmente con la aparición de las plataformas digitales de pago. Las televisiones de pago suponen un soplo de aire fresco y permiten programar en función de diferentes criterios; Este modelo de televisión no busca llegar a la gran masa sino a un público segmentado, diverso, al que trata de forma individual y, por lo tanto, no ha de adaptarse a los gustos de las audiencias mayoritarias. Pero, la nueva televisión digital viene asociada a planteamientos innovadores de programación que afectan a todas sus formas de distribución. En la TDT, el número de cadenas se multiplica, tienen mayor calidad de imagen y sonido, películas en varios idiomas, con subtítulos, interactividad... sin suscripciones ni cuotas mensuales con acceso a la emisión de cadenas autonómicas, nacionales e internacionales, lo que hace más plural la oferta televisiva.

The Principle of the Malevolent Hiding Hand; or, the Planning Fallacy Writ Large

description: We identify and document a new principle of economic behavior: the principle of the Malevolent Hiding Hand. In a famous discussion, Albert Hirschman celebrated the Hiding Hand, which he saw as a benevolent mechanism by which unrealistically optimistic planners embark on unexpectedly challenging plans, only to be rescued by human ingenuity, which they could not anticipate, but which ultimately led to success, principally in the form of unexpectedly high net benefits. Studying eleven projects, Hirschman suggested that the Hiding Hand is a general phenomenon. But the Benevolent Hiding Hand has an evil twin, the Malevolent Hiding Hand, which blinds excessively optimistic planners not only to unexpectedly high costs but also to unexpectedly low net benefits. Studying a much larger sample than Hirschman did, we find that the Malevolent Hiding Hand is common and that the phenomenon that Hirschman identified is rare. This sobering finding suggests that Hirschman's phenomenon is a special case; it attests to the pervasiveness of the planning fallacy, writ very large. One implication involves the continuing need for unbiased cost-benefit analyses and other economic decision support tools; another is that such tools might sometimes prove unreliable.

description: “Churnalism” é o termo que Natalie Fenton, professora de Jornalismo e Media em Goldsmiths, Universidade de Londres, utiliza para se referir a um novo tipo de jornalismo que se baseia no “corta e cola” e que viola os valores de ética necessários a uma esfera pública democrática. Natalie Fenton estuda a influência dos media na formação de identidades e democracia. E considera que no contexto das sociedades capitalistas, profundamente desiguais, também vivemos num dominado por ideias e identidades em circulação. A investigadora orienta o seu estudo nos pressupostos impostos pela necessidade de compreender a relação entre a autonomia individual e liberdade e a construção social da identidade num ambiente muito dominado pela influência mediática. Neste contexto, a professora de Goldsmiths, Universidade de Londres, fala-nos sobre a emergência de um novo paradigma de jornalismo, ou simplesmente a replicação de “mais do mesmo” em múltiplos canais.

description: This is a continuation of the study of strongly self-absorbing actions of locally compact groups on C*-algebras. Given a strongly self-absorbing action $γ: G\curvearrowright\mathcal{D}$, we establish permanence properties for the class of separable C*-dynamical systems absorbing $γ$ tensorially up to cocycle conjugacy. Generalizing results of both Toms-Winter and Dadarlat-Winter, it is proved that the desirable equivariant analogues of the classical permanence properties hold in this context. For the permanence with regard to equivariant extensions, we need to require a mild extra condition on $γ$, which replaces $K_1$-injectivity assumptions in the classical theory. This condition turns out to be automatic for equivariantly Jiang-Su absorbing C*-dynamical systems, yielding a large class of examples. It is left open whether this condition is redundant for all strongly self-absorbing actions, and we do consider examples that satisfy this condition but are not equivariantly Jiang-Su absorbing.

description: Context. A porous and/or fractal description can generally be applied where particles have undergone coagulation into aggregates. Aims. To characterise finite-sized, porous and fractal particles and to understand the possible limitations of these descriptions. Methods. We use simple structure, lattice and network considerations to determine the structural properties of irregular particles. Results. We find that, for finite-sized aggregates, the terms porosity and fractal dimension may be of limited usefulness and show with some critical and limiting assumptions, that highly-porous aggregates (porosity > 80%) may not be constructable. We also investigate their effective cross-sections using a simple cubic model. Conclusions. In place of the terms porosity and fractal dimension, for finite-sized aggregates, we propose the readily-determinable quantities of inflation, I (a measure of the solid filling factor and size), and dimensionality, D (a measure of the shape). These terms can be applied to characterise any form of particle, be it an irregular, homogeneous solid or a highly-extended aggregate.

External time canonical formalism for gravity in terms of embedding theory

Year: 2015
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: The formulation of gravity theory is considered where space-time is a 4-dimensional surface in flat ten-dimensional space. The possibility of using the "external" time (the time of ambient space) in this approach is investigated. The transition to the "external" time is realized with the help of partial gauge fixing, the coordinate condition which equates the timelike coordinate of the surface and time of the ambient space. It is shown that by using such a gauge condition in the action, the loss of any equations of motion does not take place, although it can happen in the general case. A version of the canonical formalism of the theory is studied in which certain additional constraints are imposed, providing the equivalence of the approach under consideration and general relativity. The corresponding first-class constraint algebra is obtained. It is proved that using the gauge directly in the action leads to the same result as gauge fixing in the constraint algebra, despite the artificial introduction of some of the constraints into the theory. Application of the "external" time may be useful for attempts to quantize the theory as well as for studies in embedding theory where 4-dimensional surfaces fill the whole ambient space and coordinates on the surfaces are not introduced.

description: The superconducting ground state of the newly discovered superconductor Cs$_2$Cr$_3$As$_3$ with a quasi-one-dimensional crystal structure ($T_{\bf c}\sim$ 2.1(1) K) has been investigated using magnetization and muon-spin relaxation or rotation ($μ$SR), both zero-field (ZF) and transverse-field (TF), measurements. Our ZF $μ$SR measurements reveal the presence of spin fluctuations below 4 K and the ZF relaxation rate ($λ$) shows enhancement below $T_{\bf c}\sim$ 2.1 K, which might indicate that the superconducting state is unconventional. This observation suggests that the electrons are paired via unconventional channels such as spin fluctuations, as proposed on the basis of theoretical models. Our analysis of the TF $μ$SR results shows that the temperature dependence of the superfluid density is fitted better with a nodal gap structure than an isotropic s-wave model for the superconducting gap. The observation of a nodal gap in Cs$_2$Cr$_3$As$_3$ is consistent with that observed in the isostructural K$_2$Cr$_3$As$_3$ compound through TF $μ$SR measurements. Furthermore, from our TF $μ$SR study we have estimated the magnetic penetration depth $λ_{\mathrm{L}}$$(0)$ = 954 nm, superconducting carrier density $n_s = 4.98 \times 10^{26}~ $m$^{-3}$, and carrier's effective-mass enhancement $m^*$ = 1.61m$_{e}$.

description: For service providers, extending the Software Defined Network (SDN) concept from packet switching in Layers 2 and 3 to circuit switching in transport layers is a promising approach to meet high burstiness and high bandwidth requirements. A multi-layer controller that can provide automated controller-based restoration and protection, even for unprotected links in a multi-administrative domain, would be a significant improvement. It would allow service providers to ensure provision of guaranteed Service Level Agreement (SLA) maintenance, with optimal bandwidth usage, high availability and reduced errors. In this thesis, we propose a Software Defined Survivable Optical Interconnect (SDSOI) architecture for Data Centers (DC). This unique architecture will address service providers’ challenges related to bandwidth management, and optimize the time required while interconnecting numerous DCs to meet the high SLA demands. The architecture is built according to the overlay SDN concept, and categorizes the application layers into online, offline and third party applications. The offline application performs the routine DC tasks, while the online application manages various dynamic DC demands. An SDSOI driven Data Center Optical Interconnect (DCOI) can handle the extensive, high quality, on-demand access to the contents. The feasibility of SDSOI is verified and demonstrated using Open Network Operating System (ONOS) as the SDN controller, Mininet as the network emulator and Optical Transport Network (OTN) as the optical framework. Our work primarily focusses on the creation of business applications in the SDSOI model, and the northbound protocols or interfaces used by the applications to interact with the controller. To verify the effectiveness of the proposed SDSOI architecture and its business applications, we simulated ‘Day Night Scheduling’, an application that combines characteristics of offline and online applications. Its primary function is to package and schedule varying DC bandwidths to service providers and optimize bandwidth usage at different times of day, along with the survivability of the interconnects.
The Effect of Psychological Stress, Training Load, and Energy Availability on the Prevalence of Athletic Amenorrhea in NCAA Division I and Division III Distance Runners

Year: 2012

description: This study quantified the prevalence of athletic amenorrhea in division (D) I and DIII distance runners and examined relationships between training load, energy availability, psychological stress, and amenorrhea. Participants (n=98) completed surveys assessing menstrual history, energy availability, psychological stress, and training load. The prevalence of amenorrhea was 20% and did not differ between divisions. Of all training parameters, only running mileage differed between divisions; DI athletes reported greater mileage (p<0.0005). There was a positive association between mileage and amenorrhea (p=0.045). Division I athletes reported greater running (p<0.0005) and overall (p=0.005) energy expenditure than DIII athletes. Energy availability did not differ between divisions and was not predictive of amenorrhea. Psychological stress did not differ between divisions, though was predictive of amenorrhea; increased psychological stress reduced the risk of amenorrhea (p=0.040). In conclusion, the prevalence of amenorrhea did not differ between divisions; only running mileage and psychological stress were predictive of amenorrhea.
Two-scale evolution during shear reversal in dense suspensions

description: We use shear reversal simulations to explore the rheology of dense, non-Brownian suspensions, resolving lubrication forces between neighbouring particles and modelling particle surface contacts. The transient stress response to an abrupt reversal of the direction of shear shows rate-independent, nonmonotonic behaviour, capturing the salient features of the corresponding classical experiments. Based on analyses of the hydrodynamic and particle contact stresses and related contact networks, we demonstrate distinct responses at small and large strains, associated with contact breakage and structural re-orientation, respectively, emphasising the importance of particle contacts. Consequently, the hydrodynamic and contact stresses evolve over disparate strain scales and with opposite trends, resulting in nonmonotonic behaviour when combined. We further elucidate the roles of particle roughness and repulsion in determining the microstructure and hence the stress response at each scale.

description: I argue that feedback is as important to formation of planets as it is to formation of stars and galaxies. Energy released by massive solid cores puffs up pre-collapse gas giant planets, making them vulnerable to tidal disruptions by their host stars. I find that feedback is the ultimate reason for some of the most robust properties of the observed exoplanet populations: the rarity of gas giants at all separations from $\sim 0.1$ to $\sim 100$~AU, the abundance of $\sim 10 M_\oplus$ cores but dearth of planets more massive than $\sim 20 M_\oplus$. Feedback effects can also explain (i) rapid assembly of massive cores at large separations as needed for Uranus, Neptune and the suspected HL Tau planets; (ii) the small core in Jupiter yet large cores in Uranus and Neptune; (iii) the existence of rare "metal monster" planets such as CoRoT-20b, a gas giant made of heavy elements by up to $\sim 50$\%.

description: In discussions at the 2015 HICSS meeting, it was argued that loads can provide most of the ancillary services required today and in the future. Through load-level and grid-level control design, high-quality ancillary service for the grid is obtained without impacting quality of service delivered to the consumer. This approach to grid regulation is called demand dispatch: loads are providing service continuously and automatically, without consumer interference. In this paper we ask, what intelligence is required at the grid-level? In particular, does the grid-operator require more than one-way communication to the loads? Our main conclusion: risk is not great in lower frequency ranges, e.g., PJM's RegA or BPA's balancing reserves. In particular, ancillary services from refrigerators and pool-pumps can be obtained successfully with only one-way communication. This requires intelligence at the loads, and much less intelligence at the grid level.
Real-space method for first-principles electron-transport calculations: self-energy terms of electrodes for large systems

description: We present a fast and stable numerical technique to obtain the self-energy terms of electrodes for first-principles electron-transport calculations. Although first-principles calculations based on the real-space finite-difference method are advantageous for execution on massively parallel computers, large-scale transport calculations are hampered by the computational cost and numerical instability of the computation of the self-energy terms. Using the orthogonal complement vectors of the space spanned by the generalized Bloch waves that actually contribute to transport phenomena, the computational accuracy of transport properties is significantly improved with a moderate computational cost. To demonstrate the efficiency of the present technique, the electron-transport properties of a Stone-Wales (SW) defect in graphene and silicene are examined. The resonance scattering of the SW defect is observed in the conductance spectrum of silicene since the $σ^\ast$ state of silicene lies near the Fermi energy. In addition, we found that one conduction channel is sensitive to a defect near the Fermi energy, while the other channel is hardly affected. This characteristic behavior of the conduction channels is interpreted in terms of the bonding network between the bilattices of the honeycomb structure in the formation of the SW defect. The present technique enables us to distinguish the different behaviors of the two conduction channels in graphene and silicene owing to its excellent accuracy.

description: We performed a deep wide-field (6.76 deg^2) near-infrared survey with the VISTA telescope that covers the entire extent of the Carina nebula complex (CNC). The point-source catalog created from these data contains around four million individual objects down to masses of 0.1 M_sun. We present a statistical study of the large-scale spatial distribution and an investigation of the clustering properties of infrared-excesses objects, which are used to trace disk-bearing young stellar objects (YSOs). We find that a (J - H) versus (Ks - [4.5]) color-color diagram is well suited to tracing the population of YSO-candidates (cYSOs) by their infrared excess. We identify 8781 sources with strong infrared excess, which we consider as cYSOs. This sample is used to investigate the spatial distribution of the cYSOs with a nearest-neighbor analysis. The surface density distribution of cYSOs agrees well with the shape of the clouds as seen in our Herschel far-infrared survey. The strong decline in the surface density of excess sources outside the area of the clouds supports the hypothesis that our excess-selected sample consists predominantly of cYSOs with a low level of background contamination. This analysis allows us to identify 14 groups of cYSOs outside the central area. Our results suggest that the total population of cYSOs in the CNC comprises about 164000 objects, with a substantial fraction (~35%) located in the northern, still not well studied parts. Our cluster analysis suggests that roughly half of the cYSOs constitute a non-clustered, dispersed population.

description: Roman emperors came to power through a hybrid dynastic/elective selection system that was never formally codified. This lack of codification has caused problems for modern scholars looking to identify and categorize those who were involved in selecting the next Roman emperor. This thesis believes that these problems exist because scholars are not distinguishing the names of key ancient institutions from the underlying types of power which backed their capability for action. This thesis seeks to solve this problem by creating a categorization system for imperial accessions based around a basic unit called the “political interest.” At its core, a political interest is a combination of the name of the individual or group as listed in the primary sources, the different types of power they possessed, and the level of decision-making authority they wielded during an imperial selection. Using this system, this thesis creates a database of Late Roman emperors with information on when they came to power, the various stages of their accessions, what political interests supported them, and where these interests were located. This thesis then analyzes the political and geographic trends from the database and supplies provisional explanations as to why changes in the Late Roman accession process occurred.

description: Context. The compositional properties of hydrogenated amorphous carbons are known to evolve in response to the local conditions. Aims. To present a model for low-temperature, amorphous hydrocarbon solids, based on the microphysical properties of random and defected networks of carbon and hydrogen atoms, that can be used to study and predict the evolution of their properties in the interstellar medium. Methods. We adopt an adaptable and prescriptive approach to model these materials, which is based on a random covalent network (RCN) model, extended here to a full compositional derivation (the eRCN model), and a defective graphite (DG) model for the hydrogen poorer materials where the eRCN model is no longer valid. Results. We provide simple expressions that enable the determination of the structural, infrared and spectral properties of amorphous hydrocarbon grains as a function of the hydrogen atomic fraction, XH. Structural annealing, resulting from hydrogen atom loss, results in a transition from H-rich, aliphatic-rich to H-poor, aromatic-rich materials. Conclusions. The model predicts changes in the optical properties of hydrogenated amorphous carbon dust in response to the likely UV photon-driven and/or thermal annealing processes resulting, principally, from the radiation field in the environment. We show how this dust component will evolve, compositionally and structurally in the interstellar medium in response to the local conditions.

description: Rising up from a chair (sit-to-stand; STS) and stair climbing are both activities of daily living (ADLs) done throughout our lives. The ability to complete ADLs is crucial for independent living. The goal of this thesis was to research how two ADLs interact with each other and affect postural control. It was hypothesized that an increased number of flights of stairs climbed would lead to a decline in postural control during/after a STS in older more than younger adults. Fourteen older adults and fourteen young adults were tested by completing three STSs before and after climbing 1, 3 and 5 flights of stairs, chosen at random. Movements of the center of pressure (COP) for each STS were obtained from a force platform. Only an age effect was found for COP velocity (left-right and anterior-posterior directions) during the momentum transfer phase, during stabilization and after stabilization. Therefore, contrary to our hypothesis, stair climbing did not lead to significant changes in COP movements during and following a STS.

description: We demonstrate that through localised Rydberg excitation in a three-dimensional cold atom cloud atomic motion can be rendered directed and nearly confined to a plane, without spatial constraints for the motion of individual atoms. This enables creation and observation of non-adiabatic electronic Rydberg dynamics in atoms accelerated by dipole-dipole interactions under natural conditions. Using the full $l=0,1$ $m=0,\pm1$ angular momentum state space, our simulations show that conical intersection crossings are clearly evident, both in atomic position information and excited state spectra of the Rydberg system. Hence, flexible Rydberg aggregates suggest themselves for probing quantum chemical effects in experiments on length scales much inflated as compared to a standard molecular situation.

description: Introduction: Increasing numbers of adults are seeking orthodontic treatment to improve their smile esthetics. The objective of this study was to determine laypeople's preferences for gingival display and buccal corridor size of the smile as a function of the age of the person smiling and the age of the evaluator. Methods: Smiling facial photos of 3 male and 3 female patients in different age groups were digitally altered to change gingival display and buccal corridor size and presented to respondents of varying ages who ranked each set based on attractiveness. Multivariate analysis was performed to determine preferences with respect to age and gender. Results: In general, people preferred a smile with smaller buccal corridors and lip position even with the gingival margin of the maxillary incisors or slightly below. Limited differences were found based on age. Conclusions: Age alone does not seem to determine smile preferences.
Preserving Local Gauge Invariance with t-Channel Regge Exchange

description: Considering single-meson photo- and electroproduction off a baryon, it is shown how to restore local gauge invariance that was broken by replacing standard Feynman-type meson exchange in the t-channel by exchange of a Regge trajectory. This is achieved by constructing a contact current whose four-divergence cancels the gauge-invariance-violating contributions resulting from all states above the base state on the Regge trajectory. To illustrate the procedure, modifications necessary for the process $γ+p \to K^+ + Σ^{*0}$ are discussed in some detail. We also provide the general expression for the contact current for an arbitrary reaction.

description: Little attention has been given to the correlation coefficient when data come from discrete or continuous non-normal populations. In this article, we consider the efficiency of two correlation coefficients which are from the same family, Pearson's and Spearman's estimators. Two discrete bivariate distributions were examined: the Poisson and the Negative Binomial. The comparison between these two estimators took place using classical and bootstrap techniques for the construction of confidence intervals. Thus, these techniques are also subject to comparison. Simulation studies were also used for the relative efficiency and bias of the two estimators. Pearson's estimator performed slightly better than Spearman's.

description: This article details the results of analyses we conducted on the discourse of schizophrenic patients, at the oral production (disfluences) and lexical (part-of-speech and lemmas) levels. This study is part of a larger project, which includes other levels of analyses (syntax and discourse). The obtained results should help us rebut or identify new linguistic evidence participating in the manifestation of a dysfunction at these different levels. The corpus contains more than 375,000 words, its analysis therefore required that we use Natural Language Processing (NLP) and lexicometric tools. In particular, we processed disfluencies and parts-of-speech separately, which allowed us to demonstrate that if schizophrenic patients do produce more disfluencies than control, their lexical richness is not significatively different.
