Résumé Cet article se propose d’étudier le lexique d’un domaine de spécialité, Internet, qui présente la particularité de n’être pas réservé à un groupe d’experts. Les termes apparaissant quasi exclusivement en langue anglaise, la question centrale est de savoir comment se traduit l’influence de l’anglais sur la terminologie du français, langue cible. Pour apporter des éléments de réponse, nous avons examiné les noms composés, qui sont particulièrement nombreux dans ce domaine. Après avoir dressé le profil morphosyntaxique des termes collectés dans notre corpus à travers l’étude de leurs structures compositionnelles, y compris la pseudo-confixation, nous avons tracé leur portrait sémantique avec une analyse de la centricité et des relations sémantiques entre leurs éléments. Notre conclusion est que le lexique français d’Internet conserve des traces de l’origine anglaise de nombreux termes mais que le nombre d’emprunts est faible.

"L’épandage de matières fertilisantes d’origine résiduaire sur les prairies comporte-t-il des risques en termes de transfert de polluants organiques et inorganiques vers la chaîne alimentaire ?"

L’objectif de cet article est d’identifier les points de vigilance relatifs aux transferts de polluants inorganiques ou organiques vers les animaux d’élevage via l’ingestion de sol, de plantes, d’eau ou encore de pédofaune, consécutivement à l’épandage de MAtières Fertilisantes d’Origine Résiduaire (MAFOR) sur les prairies. Cette identification consiste à prendre en compte simultanément les quantités de polluants ingérées (quantité de matrice ingérée × concentration du polluant dans cette matrice), la fraction biodisponible et le devenir des polluants au sein de l’organisme. Les études réalisées en conditions de terrain et qui renseignent l’ensemble des données nécessaires pour estimer l’impact des MAFOR épandues sur prairies sont rares et peu conclusives. Elles reposent principalement sur l’application des boues de stations d’épuration sur des prairies et ne permettent pas de comparer l’impact des autres formes de MAFOR. Cependant, en prenant en compte l’ensemble des connaissances sur les transferts de polluants vers les produits animaux, il apparaît que les polluants organiques sont plus fortement absorbés que les Eléments Traces Métalliques (ETM). Seuls les composés peu biotransformés s’accumulent significativement dans les produits animaux. In fine, les polluants organiques se concentrent généralement dans les tissus et produits gras alors que les ETM se retrouvent préférentiellement dans les abats. Cependant, un manque manifeste de connaissances sur le devenir de contaminants organiques émergents (bromés, perfluorés, phtalates et paraffines) ou de certains ETM (vanadium et thallium) doit être signalé. De manière globale, les transferts de polluants organiques et inorganiques vers les produits animaux, suite à l’épandage de MAFOR sur les prairies, ne peuvent être exclus.

La présence humaine à proximité des écosystèmes aquatiques a entraîné la survenue d'impacts environnementaux affectant en particulier les zones de mangroves, d'apiquons et de talus. Parmi les activités humaines dans ces écosystèmes, on peut souligner que l’élevage de crevettes a de graves incidences sur l’environnement et est une préoccupation majeure pour la société, en particulier pour les crevettes cultivées. Le fait de proposer des rations commerciales de faible qualité et d’autres sources de contamination telles que des engrais, des pesticides, des algicides et d’autres substances utilisées dans les réservoirs de culture peut contribuer à la contamination de la crevette, en favorisant la bioaccumulation de métaux traces tels que le fer, cuivre,cobalt, manganèse, zinc et chrome, dont les métaux font souvent partie de leurs composés. L’accès à la santé est l’un des droits de l’homme fondamentaux garantis par la Constitution Fédérale Brésilienne de 1988, qui intègre la notion élargie de la santé dans le contexte de l’accès et de la promotion par l’État. Ladite Constitution fait également de la nourriture adéquate un droit fondamental de l'être humain, où la sécurité alimentaire et nutritionnelle concerne, entre autres, l'accès à la nourriture et sa consommation en quantité et avec des qualités suffisantes pour nourrir l'individu et prévenir la survenue de dommages à la santé de l'individu. De cette manière, la culture de crevettes marines doit également respecter les conditions légales en matière d’environnement et d’hygiène, car ces animaux doivent être exempts de tout contaminant, introduit accidentellement ou intentionnellement pour les nourrir ou les conserver, que la législation brésilienne n’a pas réglementée. Pour assurer la sécurité alimentaire et nutritionnelle, il est nécessaire de comprendre la relation intrinsèque que l’élevage de crevettes avec l’environnement, les changements apportés aux écosystèmes impliqués et la nécessité de prendre des mesures de gestion de l’environnement et de parvenir ainsi à la durabilité socio-environnementale de cette activité.

I summarize the controversies about industrial pollutants in freshwaters near the oil sands industrial area of Alberta, the inadequacies in environmental monitoring that have led to widespread misconceptions, and recent attempts to correct the problems. Adequate data are available to show that mercury, other trace metals, and polycyclic aromatic compounds are being added by industry to the Athabasca river system and its watershed, although the relative contributions of industrial development and natural sources remain in question. Recent improvements in water monitoring by Environment Canada show promise of resolving the controversies, although independent governance for Canada’s and Alberta’s water monitoring programs in the lower Athabasca River will be necessary to rebuild public confidence in the data and their interpretation by government and industry. I document one success story in the Athabasca River: the elimination of dioxins from pulp mills in the mid-1990s has caused a consumption advisory for fish in the river to be repealed.SOMMAIREJe présente ci-dessous un résumé des controverses concernant les polluants industriels dans les eaux douces à proximité de la zone industrielle des sables bitumineux de l'Alberta, des lacunes dans la surveillance des milieux de vie à l’origine d’idées fausses répandues, et de récentes tentatives visant à corriger les problèmes. Des données adéquates démontrent que l’industrie ajoute du mercure et d'autres métaux traces ainsi que des composés aromatiques polycycliques dans le système fluvial de la rivière Athabasca et dans son bassin versant, bien que les contributions relatives provenant de ces activités industrielles et de sources naturelles demeurent toujours en litige. De récentes améliorations apportées au contrôle des eaux par Environnement Canada permettent d’espérer une résolution des controverses, mais l’application d’une gouvernance indépendante des programmes de contrôle de l'eau de l'Alberta du Canada dans la partie inférieure du fleuve Athabasca sera nécessaire pour rétablir la confiance de la population à l’égard des données présentées et de leur interprétation par le gouvernement et l'industrie. Je décrie l’histoire d’une intervention réussie dans la rivière Athabasca, soit l'élimination de dioxines provenant des usines de pâte du milieu des années 1990 et qui a abouti à l’abrogation d’un avis de limitation de la consommation de poisson dans la rivière.DOI: http://dx.doi.org/10.12789/geocanj.2013.40.012

Full textAbstract:
The ichnological assemblage from the Estancia Laguna Manantiales, from the Middle Jurassic La Matilde Formation, Santa Cruz province, Argentina, is exceptional both in diversity and abundance. It is composed of mammal, dinosaur, invertebrate, and root traces. The most significant and abundant specimens are those assigned to the ichnogenus Ameghinichnus Casamiquela, 1961. This ichnogenus is revised and an emendation of its diagnosis is suggested. The inclusion of all the known specimens to the type ichnospecies, Ameghinichnus patagonicus Casamiquela, 1961, is challenged and some specimens are placed in a new ichnospecies, Ameghinichnus manantialensis isp. nov. Similar tracks from other ichnological localities worldwide were previously referred to Ameghinichnus, but only Eopentapodiscus (Ellenberger, 1970), from South Africa is considered as a junior synonym of Ameghinichnus. The ichnotaxobases used to classify tracks with mammalian affinities at ichnogeneric and ichnospecific levels are evaluated and re-assessed ichnotaxonomic criteria are proposed. Different criteria used to distinguish mammalian imprints from non-mammalian tracks are commented.

Full textAbstract:
This essay will examine the manner in which composers and artistic directors have used conductors and click-tracks within the context of new music ensembles performing integrative concerts. The analyses and examples provided will rely for the most part on material gathered during in-depth interviews that I conducted with artistic directors, composers, conductors, and musicians, all of whom are professionally active in the new music field in Europe (and beyond). I will examine the application of both click-tracks and conductors and demonstrate that their implementation represents an active choice made by either the composer and/or artistic directors. Both click-tracks and conductors are viewed by the interviewees as potential tools with somewhat overlapping possibilities and capacities and their presence is no secondary phenomenon of the music. They become instead a means for the above actors to meet their objectives, be they artistic, pragmatic, technical, or otherwise.

This paper attempts to identify the pragmatic constraints that license the use of the present perfect with a future time adverb in French, such as J'ai bientôt fini (lit. 'I have soon finished') or Dans une heure, le président est sorti de sa réunion (lit. 'In an hour, the president has exited from his meeting'). Previous studies have argued that only aspectual verbs are available in such constructions, and that a pragmatic notion of planification must be accessible to the interlocutors, hence utterances like Demain il a plu ('Tomorrow it has rained') or Demain Pierre a été heureux ('Tomorrow Pierre has been happy') are odd. The paper suggests that some of the concerned utterances are fine, despite their lack of agentivity, so long as that doesn't merely presuppose planification but rather serves to communicate that a particular attitude, or course of actions has to be adopted in the present from the perspective of the/a future state of affairs.

Full textAbstract:
Abstract A next generation of tau PET tracers for the imaging of Alzheimer’s disease and other dementias has recently been developed. Whilst the new compounds have now entered clinical studies, there is limited information available to assess their suitability for clinical applications. Head-to-head comparisons are urgently needed to understand differences in the radiotracer binding profiles. We characterized the binding of the tau tracers PI2620, RO948, MK6240 and JNJ067 in human post-mortem brain tissue from a cohort of 25 dementia cases and age-matched controls using quantitative phosphorimaging with tritium-labelled radiotracers in conjunction with phospho-tau specific immunohistochemistry. The four radiotracers depicted tau inclusions composed of paired helical filaments with high specificity, both in cases with Alzheimer’s disease and in primary tauopathy cases with concomitant Alzheimer’s disease pathology. In contrast, cortical binding to primary tauopathy in cases without paired helical filament tau was found to be within the range of age-matched controls. Off-target binding to monoamine oxidase B has been overcome, as demonstrated by heterologous blocking studies in basal ganglia tissue. The high variability of cortical tracer binding within the Alzheimer’s disease group followed the same pattern with each tracer, suggesting that all compounds are suited to differentiate Alzheimer’s disease from other dementias.

AbstractThis article presents a view of the first meetings between the oboe virtuoso Christopher Redgate and the composers Dorothy Ker and Fabrice Fitch. The article details some aspects of these meetings to highlight the processes that are at play in the earliest stages of collaboration. These processes are both practical (in which information about how the oboe works is uncovered and shared) and philosophical (in which the oboe itself becomes a significant source of new possibilities). The article traces a period during which Redgate was developing a new oboe, working with composers to create new repertoire for the new instrument. Arguing for closer attention to the ‘everyday’ aspects of composers and performers working together, the article explores some of the ways in which Redgate pulls apart his experience of performing to develop new technique and to opening up new possibilities for future composition. I also argue that the oboe, as much as the composer and performer, plays a part in shaping musical outcomes.

Abstract. Understanding the mechanics of bed load at the flood scale is necessary to link hydrology to landscape evolution. Here we report on observations of the transport of coarse sediment tracer particles in a cobble-bedded alluvial river and a step-pool tributary, at the individual flood and multi-annual timescales. Tracer particle data for each survey are composed of measured displacement lengths for individual particles, and the number of tagged particles mobilized. For single floods we find that: measured tracer particle displacement lengths are exponentially distributed; the number of mobile particles increases linearly with peak flood Shields stress, indicating partial bed load transport for all observed floods; and modal displacement lengths scale linearly with excess shear velocity. These findings provide quantitative field support for a recently proposed modelling framework based on momentum conservation at the grain scale. Tracer displacement shows a weak correlation with particle size at the individual flood scale, however cumulative travel distance begins to show an inverse relation to grain size when measured over many transport events. The observed spatial sorting of tracers approaches that of the river bed, and is consistent with size-selective deposition models and laboratory experiments. Tracer displacement data for the step-pool and alluvial channels collapse onto a single curve – despite more than an order of magnitude difference in channel slope – when variations of critical Shields stress and flow resistance between the two are accounted for. Results show how bed load dynamics may be predicted from a record of river stage, providing a direct link between climate and sediment transport.

By use of light microscopy and fluorescence photobleaching recovery, we have studied (a) structures that form in a system composed of copolymerized rabbit muscle actin and chicken gizzard filamin and (b) the Brownian motion of inert tracer macromolecules in this matrix. We have used as tracers size-fractionated fluorescein-labeled ficoll and submicron polystyrene latex particles. In F-actin solutions, the relative diffusion coefficient of the tracer was a decreasing function of both tracer size and actin concentration. Also, a percolation transition for latex particle mobility was found to follow a form suggested by Ogston (Ogston, A. G. 1958. Trans. Faraday Soc. 54:1754-1757) for random filament matrices. The inclusion of filamin before polymerization resulted in increased tracer mobility. Below a filamin dimer-to-actin monomer ratio of 1:140, no structural features were observed in the light microscope. At or above this ratio for all actin concentrations tested, a three-dimensional network of filament bundles was clearly discriminated. Latex particles were always excluded from the bundles. By use of a dialysis optical cell in which polymerization could be initiated with very little hydrodynamic stress, we found that filamin can spontaneously bundle F-actin. A simple physical picture explains how dynamics can affect the structural result of coassembly and provides a further hypothesis on the balance between random filament cross-linking and large-scale bundling. Control of this balance may be important in cytoplasmic motile events.

Tracing is a popular method for evaluating, investigating, and modeling the performance of today's storage systems. Tracing has become crucial with the increase in complexity of modern storage applications/systems, that are manipulating an ever-increasing amount of data and are subject to extreme performance requirements. There exists many tracing tools focusing either on the user-level or the kernel-level, however we observe the lack of a unified tracer targeting both levels: this prevents a comprehensive understanding of modern applications' storage performance profiles. In this paper, we present EZIOTracer, a unified I/O tracer for both (Linux) kernel and user spaces, targeting data intensive applications. EZIOTracer is composed of a userland as well as a kernel space tracer, complemented with a trace analysis framework able to merge the output of the two tracers, and in particular to relate user-level events to kernel-level ones, and vice-versa. On the kernel side, EZIOTracer relies on eBPF to offer safe, low-overhead, low memory footprint, and flexible tracing capabilities. We demonstrate using FIO benchmark the ability of EZIOTracer to track down I/O performance issues by relating events recorded at both the kernel and user levels. We show that this can be achieved with a relatively low overhead that ranges from 2% to 26% depending on the I/O intensity.

Amongst the most fascinating discoveries made in recent years was the identification of the Egyptian songstress Iti (2450 BC) as the first woman composer to have been mentioned by name in musical history. This paper examines the status of professional women musicians in Ancient Egypt, their role in society and their contribution to various aspects of life and death. Reviewing the range of styles, practices and variety of instrumental and vocal ensembles in which women took part as composers, performers and instructors, the author traces the development of a musical tradition which would appear to throw light upon some long standing prejudices, and to have important implications for music education in multi-cultural schools today.

Abstract. Secondary organic aerosol (SOA) formation from biogenic precursors is affected by anthropogenic emissions, which are not well understood in polluted areas. In this study, we accomplished a year-round campaign at nine sites in polluted areas located in the Pearl River Delta (PRD) region during 2015. We measured typical biogenic SOA (BSOA) tracers from isoprene, monoterpenes, and β-caryophyllene, as well as major gaseous and particulate pollutants and investigated the impact of anthropogenic pollutants on BSOA formation. The concentrations of BSOA tracers were in the range of 45.4 to 109 ng m−3 with the majority composed of products from monoterpenes (SOAM, 47.2±9.29 ng m−3), isoprene (SOAI, 23.1±10.8 ng m−3), and β-caryophyllene (SOAC, 3.85±1.75 ng m−3). We found that atmospheric oxidants, Ox (O3 plus NO2), and sulfate correlated well with later-generation SOAM tracers, but this was not the case for first-generation SOAM products. This suggested that high Ox and sulfate levels could promote the formation of later-generation SOAM products, which probably led to the relatively aged SOAM that we observed in the PRD. For the SOAI tracers, both 2-methylglyceric acid (NO/NO2-channel product) and the ratio of 2-methylglyceric acid to 2-methyltetrols (HO2-channel products) exhibit NOx dependence, indicating the significant impact of NOx on SOAI formation pathways. The SOAC tracer was elevated in winter at all sites and was positively correlated with levoglucosan, Ox, and sulfate. Thus, the unexpected increase in SOAC in wintertime might be highly associated with the enhancement of biomass burning, O3 chemistry, and the sulfate component in the PRD. The BSOAs that were estimated using the SOA tracer approach showed the highest concentration in fall and the lowest concentration in spring with an annual average concentration of 1.68±0.40 µg m−3. SOAM dominated the BSOA mass all year round. We also found that BSOA correlated well with sulfate and Ox. This implied a significant effect from anthropogenic pollutants on BSOA formation and highlighted that we could reduce BSOA by controlling the anthropogenic emissions of sulfate and Ox precursors in polluted regions.

Full textAbstract:
Fenestrate microbialites from the 2521±3 Ma Gamohaan Formation, South Africa, are composed of calcite with traces of kerogen that represent the remains of ancient microbial mats. To delineate the 3-D geometry of these microbialites, specimens were serial-sectioned; sequential slices were polished in 120 μm increments and scanned to yield an image stack, which was rendered into a virtual model of the microbialites. The resulting virtual representation allowed for visualization and characterization of microbial growth geometries that were not visible from 2-D surfaces. Several new insights into the structure of microbialites emerged from characterizing their 3-D structure including the recognition of two new features, linear structures and tubular structures. The long, thin nature of these structures makes them difficult to identify in two dimensions. However, in three dimensions, they can be traced as thin ropes of fossilized microbial communities emerging from more typical microbial mat structures. Overall, these results demonstrate a new set of microbial features in the Gamohaan Formation that were only characterized by reconstructing the full geometry of the microbialites in three dimensions.

AbstractAugusta Browne Garrett composed at least two hundred piano pieces, songs, duets, hymns, and sacred settings between her birth in Dublin, Ireland, around 1820, and her death in Washington, D.C., in 1882. Judith Tick celebrated Browne as the “most prolific woman composer in America before 1870” in her landmark study American Women Composers before 1870. Browne, however, cast an enduring shadow as an author as well, publishing two books, a dozen poems, several Protestant morality tracts, and more than sixty music essays, nonfiction pieces, and short stories. By means of her prose publications, Augusta Browne “put herself into the text—as into the world, into history—by her own movement,” as feminist writer Hélène Cixous urged of women a century later. Browne maintained a presence in the periodical press for four decades in a literary career that spanned music journalism, memoir, humor, fiction, poetry, and Christian devotional literature, but one essay, “The Music of America” (1845), generated attention through the twentieth century. With much of her work now easily available in digitized sources, Browne's life can be recovered, her music experienced, and her prose reassessed, which taken together yield a rich picture of the struggles, successes, and opinions of a singular participant and witness in American music of her era.

The object of this research is the piano compositions of Alban Berg – the String Quartet, Op. 3, and the vocal cycle Altenberglieder, Op. 4. The subject of this research is the artistic transformation of Berg from amateur composer of romantic music to the author of the complex atonal composition. The article reviews the aspects of Berg's apprenticeship that impacted his professional becoming. The peculiarities of the pedagogical method the composer's mentor and friend. Arnold Schoenberg are described. The author systematizes Berg's musical impressions acquired in his earlier period, which revealed the world of “new tones”. Special attention is given to the personal qualities of Alban Berg, his desire to cognize the new musical world. Analysis is conducted on the piano pieces composed at the time of his study with Schoenberg is. Opuses 3 and 4 are examined for the similar authorial techniques and their gradual complication. The conclusion is made that the phenomenon of rapid changes in the composer's artistic path is substantiated by a combination of factors. Berg was able to overcome the initially romantic melodious nature in his composing due to the opportunity to be in Vienna, which was the center of musical life at that time and the pedagogical talent of A. Schoenberg. The key character traits of the composer were commitment, capacity to work, and strive for creative truth. His natural enthusiasm and sensitivity were balanced by mathematical meticulousness and propensity for systematization. This served as the foundation for the remarkable changes that can be traces from his apprentice sketches to the first independent composition – the vocal cycle Altenberglieder, Op. 4. The scientific novelty of this research consists in posing the question of how Berg was able to develop such complex modern language in a very short period of time that elevated him to the forefront of leading composers.

Статья посвящена сочинению из лейпцигского репертуара И. С. Баха— «Страстям по Марку», которые ранее ошибочно приписывали Р. Кайзеру. Прослеживается судьба всех сохранившихся источников «Страстей по Марку», описывается длительная история изучения этой группы рукописей и сопутствующая ему научная полемика. Освещаются существующие гипотезы об авторстве, а также времени и месте возникновения произведения, которое послужило основой для всех последующих редакций,— как баховских, так и принадлежащих другим авторам. Кроме того, прослеживается возможный вклад Баха как редактора и соавтора в те версии, которые были подготовлены и, по-видимому, исполнены им в разные годы службы. На материале номеров, предположительно созданных великим композитором, показывается художественный и духовный смысл его версий этого сочинения— в особенности лейпцигских редакций 1726 и 1740‑х годов, последняя из которых представляет собой пастиччо с добавленными ариями из «Брокес-Пассионов» Г. Ф. Генделя. The article is concerned with the work from the Leipzig repertoire of J. S. Bach— “St. Mark Passion”, which was previously mistakenly attributed to R. Keiser. An essay traces the fate of all the surviving sources of the work, describing the long history of studying this entire group of manuscripts and the scientific controversy accompanying this study. Existing hypotheses about authorship, as well as the time and the place of origin of the work, which served as the basis for all subsequent revisions, both Bach’s and those of other composers, are highlighted. In addition, the possible contribution of Bach as an editor and coauthor to those versions that were prepared and, apparently, performed by him in different years of service, is traced. The material of the numbers, supposedly created by the great composer, shows the artistic and spiritual meaning of his versions of this work, especially the Leipzig editions of 1726 and 1747, the last of which is pasticcio with added arias from Brockes-Passions by G. Fr. Handel.

Abstract The paper examines how members of the “Cluj/Kolozsvár School” of composition, the disciples of Sigismund Toduţă, Gábor Jodál, Max Eisikovits and János Jagamas dealt with the influence of Bartók. One can find traces of Bartókian influence in the work of Transylvanian composers beginning from the 1950s, a series of hommage-compositions being written on the occasion of Bartók-anniversaries in 1965, 1970 and especially 1981. The last piece mentioned was composed in 1998. The paper focuses on the cases of five individual composers: Cornel Ţăranu, Ede Terényi, Péter Vermesy, György Orbán and Boldizsár Csíky. In addition to the analysis of certain compositions à la Bartók written by them, their declarations as well as the role of Ernő Lendvai's theories are taken into consideration. A distinction is made among (1) the arrangements of folk music melodies collected by Bartók, (2) the hommage-pieces containing quotations from Bartók's art music, and finally, (3) those longer or shorter periods in a composer's career in which Bartók's influence can be detected in a whole series of compositions.

Full textAbstract:
The origins of the Roman intermezzo, an important and influential sub-genre of Italian comic opera, can be traced back to the 1730s, when the composer and librettist Benedetto Micheli wrote several two-part intermezzi for the Teatro Valle and other theaters in Rome for performance during the intermissions of spoken plays. The Valle cultivated the intermezzo with particular consistency during the next six decades, presenting works by many distinguished composers, including Sacchini, Paisiello, and Cimarosa. Sacchini's La contadina in corte, on a libretto derived from Giacomo Rust's three-act comic opera of the same title, may serve as a good example of the Roman intermezzo.

Full textAbstract:
Purpose Herbert Brün was a composer of many things including electronic and computer music. His compositions were, by design, nested in his passions for designing a new society – without violence. In this article, the author attempts to address several of Brün’s concepts relevant to his desire for social change. This paper was stimulated by a panel discussion about Brün at the 2018 American Society for Cybernetics (ASC) conference “Framing a Reality and How It Matters in a Shared World.” Design/methodology/approach Herbert Brün nested his communication in what he labeled “anticommunication,” which requires a listener to generate new ways of listening. As a video ethnographer, the author had many opportunities to videotape Brün, beginning with our first encounter at the 1992 ASC Conference in Washington State. During the past several decades, the author has composed a variety of movies in which the video footage of Brün and others that the author associates with cybernetics is used. Excerpts from many of these movies are embedded in the links located in the references section of this paper. Findings Brün’s cybernetic formulations for designing social transformations explored in this paper include his ideas on floating hierarchies, anticommunication, his notions on a circularity of needs, peace as a need, articulating desires, composing as an element of daily life, and the retardation of decay. Originality/value It is the author’s desire that this paper encourages the reader to explore some of Herbert Brün’s formulations for designing social change and transformations.

Full textAbstract:
The mammalian brain is composed of densely connected and interacting regions, which form structural and functional networks. An improved understanding of the structure–function relation is crucial to understand the structural underpinnings of brain function and brain plasticity after injury. It is currently unclear how functional connectivity strength relates to structural connectivity strength. We obtained an overview of recent papers that report on correspondences between quantitative functional and structural connectivity measures in the mammalian brain. We included network studies in which functional connectivity was measured with resting-state fMRI, and structural connectivity with either diffusion-weighted MRI or neuronal tract tracers. Twenty-seven of the 28 included studies showed a positive structure–function relationship. Large inter-study variations were found comparing functional connectivity strength with either quantitative diffusion-based (correlation coefficient (r) ranges: 0.18–0.82) or neuronal tracer-based structural connectivity measures (r = 0.24–0.74). Two functional datasets demonstrated lower structure–function correlations with neuronal tracer-based (r = 0.22 and r = 0.30) than with diffusion-based measures (r = 0.49 and r = 0.65). The robust positive quantitative structure–function relationship supports the hypothesis that structural connectivity provides the hardware from which functional connectivity emerges. However, methodological differences between the included studies complicate the comparison across studies, which emphasize the need for validation and standardization in brain structure–function studies.

Abstract During December 2006 many cyclones traveled across the North Atlantic, causing temperature and precipitation in Norway to be well above average. Large excursions of high vertically integrated water vapor, often referred to as atmospheric rivers, reached from the subtropics to high latitudes, inducing precipitation over western Scandinavia. The sources and transport of atmospheric water vapor in the North Atlantic storm track during that month are examined by means of a mesoscale model fitted with water vapor tracers. Decomposition of the modeled total water vapor field into numerical water vapor tracers tagged by evaporation latitude shows that when an atmospheric river was present, a higher fraction of water vapor from remote, southerly source regions caused more intense precipitation. The tracer transport analysis revealed that the atmospheric rivers were composed of a sequence of meridional excursions of water vapor, in close correspondence with the upper-level flow configuration. In cyclone cores, fast turnover of water vapor by evaporation and condensation were identified, leading to a rapid assimilation of water from the underlying ocean surface. In the regions of long-range transport, water vapor tracers from the southern midlatitudes and subtropics dominated over local contributions. By advection of water vapor along their trailing cold fronts cyclones were reinforcing the atmospheric rivers. At the same time the warm conveyor belt circulation was feeding off the atmospheric rivers by large-scale ascent and precipitation. Pronounced atmospheric rivers could persist in the domain throughout more than one cyclone's life cycle. These findings emphasize the interrelation between midlatitude cyclones and atmospheric rivers but also their distinction from the warm conveyor belt airstream.

In 2022, two significant dates are celebrated: the 150th anniversary of the birth of S. P. Diaghilev (1872–1929), entrepreneur, creator and head of the "Russian Seasons" enterprise in Paris, and the 140th anniversary of the birth of I. F. Stravinsky, an outstanding composer. Based on documentary evidence, the article traces the nature of the interaction between the two creators in certain periods of their joint work. At the same time, it is noted that the fates of the two figures of Russian culture were closely intertwined in terms of personal friendship. They also had much in common: both Diaghilev and Stravinsky were brought up in families where art and music were deeply revered, both studied at Saint Petersburg University and took lessons from professors of the Saint Petersburg Conservatory. The composer and the entrepreneur collaborated for a long period in the Parisian "Saisons Russes", for which Stravinsky composed twelve operas and ballets. Their creative collaboration in the Diaghilev project lasted eighteen years. Fate surprisingly brought them together after their demise, both Stravinsky and Diaghilev rested with a difference of 42 years on the island-cemetery of San Michele in Venice.

Full textAbstract:
The compound vascular bundles in the <em>Aristolochia clematitis</em> stems are entirely composed of leaf traces. At the stage of protoxylem differentiation there is not one vessel in the compound vascular bundle which would belong solely to the stem. In a mature compound vascular bundle less xylem belongs to traces of higher lying leaves than to these of the lower situated ones. The lower ends of the particular traces, components of the compound vascular bundle, gradually become thinner. The traces of the upper leaves are represented in the xylem of the compound vascular bundle in the lower parts of the stem by several or even by only one metaxylem vessel. The latter constitutes a „trace" of the participation of the given leaf in the development of the compound vascular bundle. There are two categories of compound bundles in the stem. One part of these bundles does not reach to the stem apex and they develop on one side. They consist of halves (right and left) of traces of median lower leaves from one orthostichy. The others run uninterruptedly from the base to the stem tip and develop from the middle. They consist, namely, of the median traces (left or right) of lower leaves from the orthostichy and lateral leaf traces (left or right) from the second orthostichy.

The increasing interest in children and young people as composers, as evidenced by the growing literature on the subject in recent years, has tended to overlook at least one important aspect of young composers' development: their sense of tonal thinking, its emergence and consolidation. This article traces these characteristics through the compositions of one boy, showing how he ‘progressed’ from pre-tonal operations to fully-established tonal procedures. The discussion of his development is deliberately limited to the examination of harmonic thinking, which manifests itself before long(er)-range tonal planning (in the form of tonality or key schemes) becomes a focus of concern.

Purpose. To study traces of plastic deformation in quartz of crystalline rocks of the Sea of Azov. Methodology. Work was done in the field to observe the crystallinity of the crystalline rocks of the Sea of Azov. In laboratory conditions, samples were made from samples taken of rocks and quartz, in which traces of plastic deformation were observed qualitatively by visual and optical methods by transmission and reflection. In natural and ultraviolet light, the physical properties of quartz were quantified, and the effects of luminescence in quartz samples and quartz sandstone material were studied and analyzed. Results. The forms of manifestation of quartzity in crystalline rocks of the Azov Sea were studied, geological bodies composed of quartz were tested, samples were taken from samples taken to observe traces of plastic deformation. The fact of luminescence of granular quartz was established, in which traces of plastic deformation act as luminescence centers. The luminescence of Donbass Carboniferous sandstones is shown, in which quartz grains, which bear traces of plastic deformations, serve as luminescence centers. Scientific novelty. A scientific fact has been established that traces of plastic deformation serve as centers of luminescence of quartz. Practical significance. The established effect of the relationship between quartz luminescence and traces of plastic deformation can be used in the field as a diagnostic sign of plastic deformation of quartz and in mine ones for qualitative control of the impact hazard of Donbass sandstones. Keywords: quartz content, granular quartz, luminescence, luminescence center, traces of plastic deformation, impact hazard of sandstones.

Seismic traces are signals composed of information and noise. In essence, the part of the data set that is noise obscures the information and complicates the processing and interpretation of the seismic traces. Of the two procedures discussed, one is maximum standard deviation for an optimum threshold, and the other is the data transformation by variance. Either or both procedures can be used to enhance signal‐to‐noise (S/N) ratio. The procedures are data processing steps that are applied to each trace. Examples of successful application of the procedures are presented.

Full textAbstract:
This article examines the nature of skilled practice within two settings of musical performance, the rehearsal and the compositional workshop. Drawing primarily on the work of Richard Sennett and Tim Ingold, I suggest that a characterisation of musical performance as a craft practice attends to the development of skill and expertise through the performer’s physical and everyday encounters with the world and provokes a reconsideration of the dimensions of performance that might otherwise be taken for granted. The first case study addresses rhythmic coordination during a rehearsal of Four Duets for clarinet and piano (2012), composed by Edmund Finnis for Mark Simpson and Víkingur Ólafsson, and the second traces the development of instrumental techniques by composer Evan Johnson and performer Carl Rosman as they collaborate on a new work for historical basset clarinet, ‘indolentiae ars’, a medium to be kept (2015). The article makes the case for skilled practice as an improvisatory interplay between performers and the meshwork of people, objects, histories and processes which they inhabit.

The context of any workflow has functional and non functional characteristics. Functional characteristics give rise to Workflow Patterns (WPs) in a workflow. Changes may occur to the relationships amongst patterns in a workflow after the initial enactment. Run-time changes could occur due to roles executing the patterns. Design-time changes could occur due to changing user specifications and subsequent decisions being taken by the workflow composer. An approach of accommodating and propagating such changes is required. These changes are to be accommodated in a manner that the relationships amongst the existing patterns remain consistent. This paper formalizes an approach that facilitates composition and accommodation of changes into a composed workflow maintaining consistency. We make use of tools and algorithms from Formal Concept Analysis (FCA) to organize WPs as a lattice. Graph searching techniques are exploited for composition of the workflow graph. For accommodating changes into the composed workflow, we consider the WPs as Reference Intervals from Allen's Interval Algebra (IA) framework. Change accommodation in our approach is achieved by three functionalities - a transform function that traces a Reference Interval Hierarchy (RIH) from the workflow graph; a constraint propagation function that accommodates raised changes into the RIH; an inverse transform function that updates the corresponding workflow graph with the changes in the RIH.

The Uruguayan continental margin was generated following the fragmentation of the Gondwana supercontinent and the subsequent opening of South Atlantic Ocean. It constitutes an extensive sedimentation area in which three sedimentary basins can be found: the Punta del Este Basin, the southernmost portion of the Pelotas Basin, and the poorly defined Oriental del Plata Basin. The aim of this work was the identification and characterization of the different seismic units (seismic facies, systems tracts, depositional sequences) for the sedimentary interval assigned to the Eocene in the Uruguayan continental margin. Sequence stratigraphy was used as a basin analysis method for this purpose, using a database that consisted of approximately 10,000 kilometers of 2D seismic sections, acquired in exploratory surveys in 2007 and 2008. The workflow included the recognition of stacking patterns and/or stratal terminations, the definition of genetically significant stratigraphic surfaces and, based on these, the identification of systems tracts and depositional sequences. Three depositional sequences were identified in the studied sedimentary interval. The basal sequence is composed of four depositional systems tracts, including falling stage, normal regression (lowstand and highstand) and transgressive deposits. The intermediate sequence only preserves lowstand normal regression deposits. The third sequence is composed by three depositional systems tracts, including lowstand, transgressive and falling stage deposits. ResumoA margem continental uruguaia foi gerada após a fragmentação do supercontinente Gondwana e a subsequente abertura do Oceano Atlântico Sul. Constitui uma extensa área de sedimentação em três bacias sedimentares: a bacia de Punta del Este, a porção mais ao sul da Bacia de Pelotas e a Bacia Oriental del Plata, pouco definida. O objetivo deste trabalho foi a identificação e caracterização das diferentes unidades sísmicas (fácies sísmicas, tratos de sistemas, seqüências deposicionais) para o intervalo sedimentar atribuído ao Eoceno na margem continental uruguaia. Com este objetivo, utilizou-se a estratigrafia de seqüencias como método de análise de bacias, tendo-se utilizado um banco de dados constituído por aproximadamente 10.000 km de seções sísmicas 2D, adquiridas em pesquisas exploratórias em 2007 e 2008. O trabalho incluiu o reconhecimento de padrões de empilhamento e/ou terminações estratais, a definição de superfícies estratigráficas geneticamente significativas, tendo-se efetuado com base nelas, a identificação de tratos de sistemas e seqüências deposicionais. Três seqüências deposicionais foram identificadas no intervalo sedimentar estudado. A seqüência basal é composta por quatro tratos de sistemas deposicionais, incluindo a fase de abaixamento do nível do mar, a regressão normal e depósitos transgressivos. A sequência intermediária apenas preserva os depósitos de regressão normais de nível de mar baixo. A terceira seqüência é composta por três tratos de sistemas deposicionais, incluindo depósitos de nível de mar baixo, transgressivos e de abaixamento do nível do mar.

Full textAbstract:
The drilling of the Rio Tinto basement has provided evidence of an underground microbial community primarily sustained by the Fe and S metabolism through the biooxidation of pyrite orebodies. Although the gossan is the microbial activity product, which dates back to the Oligocene (25 Ma), no molecular evidence of such activity in the past has been reported yet. A Time of Flight Secondary Ion Mass Spectrometry (ToF-SIMS) molecular analysis of a subsurface sample in the Peña de Hierro basement has provided novel data of the ancient underground microbial community. It shows that the microbial remains are preserved in a mineral matrix composed of laminated Fe-oxysulfates and K- and Na-bearing sulfates alternating with secondary silica. In such a mineral substrate, the biomolecule traces are found in five different microstructure associations, (1) <15 micron-sized nodular microstructures composed of POn(2≤n≤4)−, (2) <30 micron-size micronodules containing fatty acids, acylglycerides, and alkanol chains, (3) <20 micro-sized nodules containing NOn−(2≤n≤3) ions, (4) 40-micron size nodules with NH4+ and traces of peptides, and (5) >200-micron thick layer with N-bearing adducts, and sphingolipid and/or peptide traces. It suggests the mineralization of at least five microbial preserved entities with different metabolic capabilities, including: (1) Acidiphilium/Tessaracoccus-like phosphate mineralizers, (2) microbial patches preserving phosphate-free acylglycerides bacteria, (3) nitrogen oxidizing bacteria (e.g., Acidovorax sp.), (4) traces of heterotrophic ammonifying bacteria, and (5) sphingolipid bearing bacteria (e.g., Sphingomonadales, and δ-Proteobacteria) and/or mineralized biofilms. The primary biooxidation process acted as a preservation mechanism to release the inorganic ions that ultimately mineralized the microbial structures.

In the present article the author presents a review of piano preludes written by Moldovan composers in the second half of 20th century which are frequently studied at the Academy of Music, Theatre and Fine Arts of the Republic of Moldova. The author seeks to characterize their imagery, musical language means and technical difficulties that can be encountered by young performers. The works analyzed are approved in the author's teaching practice. The preludes were written by Gheorghe Neaga, Vladimir Rotaru, Semion Lungul, Constantin Rusnac, Alexei and Marian Stârcea, Vitaly Sechkin. Some information about these miniatures can be found in research by musicologists E. Kletinich, A. Miroshnikova, E. Gupalova. A detailed analysis from a performer's standpoint presented in the article is made for the first time. The piano pieces indicated above are diverse. The two preludes by A. Stârcea contrast with one another: one has a lyrical character, whereas the other one differs in its drama and flustered character. The piece by Gh. Neaga bears the traces of impressionist music. C. Rusnac’s and V. Rotaru’s creations are composed using Moldovan doina stylistics, and S. Lungul’s lyrical miniature is nationally neutral. In the two preludes by M. Stârcea, modern musical language means are used, and sharp rhythms and dissonant harmonies abound. The article also presents five preludes-pictures by Vitaly Sechkin, a Ukrainian composer who spent his last period of life in Moldova. Inspired by Moldovan vivid landscapes, they differ in their imagery and tempo. Nonetheless, each of the miniatures has its own individual appearance and peculiarities of style. All the works reviewed are distinguished by bright themes and original music language. They represent a substantial enrichment of national piano repertoire and are a striking contribution of autochthonous authors to the development of the prelude genre in the world’s piano music.

Verification is decisive for embedded software. The goal of this work is to verify temporal properties on industrial applications, with the help of formal dynamic analysis. The approach presented in this paper is composed of three steps: formalization of temporal properties using an adequate language, generation of execution traces from a given property and verification of this property on execution traces. This paper focuses on the verification step. Use of a new kind of Büchi automaton has been proposed to provide an efficient verification taking into account the industrial needs and constraints. A prototype has been developed and used to carry out experiments on different anonymous real industrial applications.

Full textAbstract:
An automotive junction box distributes electric power to electric systems installed in a vehicle with overcurrent protection. As a larger number of electric systems are installed, the junction box is equipped with more components, functionalities and connections. However, owing to the fuse accessibility, its installation space is so restricted that a downsized design is required for the junction box. The junction box is composed of small signal circuitry for control and monitoring, and large current-carrying circuitry for power distribution which includes many parallel traces. Because of these unique features, widely used techniques for downsizing printed-circuit boards are not applicable. Also, there is no rule for designing large current-carrying parallel traces, and it is difficult to optimize the size of the printed-circuit board for the automotive junction box. This paper presents the design rules for a printed-circuit board when downsizing a junction box. First, the layout strategy for the power distribution components is presented, which is determined by the sum of the squares of the currents flowing through connector pairs. Then, the thermal effects of parallel traces are simulated for different conditions by using thermal analysis software. Based on the results, an analytical estimation of the additional temperature rises due to parallel traces and rules for a thermally effective arrangement of the parallel traces are presented.

Several common and debilitating neurodegenerative disorders are characterized by the intracellular accumulation of neurofibrillary tangles (NFTs), which are composed of hyperphosphorylated tau protein. In Alzheimer’s disease (AD), NFTs are accompanied by extracellular amyloid-beta (Aβ), but primary tauopathy disorders are marked by the accumulation of tau protein alone, including forms of frontotemporal dementia (FTD), corticobasal degeneration (CBD), and progressive supranuclear palsy (PSP), among others. 18F-THK5351 has been reported to bind pathological tau as well as associated reactive astrogliosis. The goal of this study was to validate the ability of the PET tracer 18F-THK5351 to detect early changes in tau-related pathology and its relation to other pathological hallmarks. We demonstrated elevated in vivo 18F-THK5351 PET signaling over time in transgenic P301S tau mice from 8 months that had a positive correlation with histological and biochemical tau changes, as well as motor, memory, and learning impairment. This study indicates that 18F-THK5351 may help fill a critical need to develop PET imaging tracers that detect aberrant tau aggregation and related neuropathology in order to diagnose the onset of tauopathies, gain insights into their underlying pathophysiologies, and to have a reliable biomarker to follow during treatment trials.

Enclavé dans une région connue comme la Mixteca, le village de San Pedro, composé à 80% d'une population du groupe ethno-linguistique amuzgo, constitue avec Ipalapa, son voisin de moindre importance numérique, l'un des deux seuls villages de Oaxaca de population amuzga. Les autres Amuzgos se trouvent dans l'état voisin de Guerrero. Malgré son existence préhispanique certaine, on sait fort peu de choses concernant ce groupe, tant à l'époque préhispanique qu'à l'époque coloniale. Ce vide persiste pratiquement jusqu'à nos jours. La langue amuzga, constitue, selon, un consensus admis par les linguistes, une des sept ramifications du groupe de langues otomangues. L'autonomie ou non de cette langue par rapport aux autres ramifications, et notamment au mixtèque, reste un point d'interrogation. Cependant le terme amuzgo ne correspond ni a l'auto-définition de ses habitants ni même à la désignation de cette langue dans la langue même. À San Pedro on parle jñonda, et à lpalapa ñunda, ce qui correspond littéralement à “parole d'eau”.

We investigate certain matrices composed of mixed, second-order moments of unitaries. The unitaries are taken from $C^*$-algebras with moments taken with respect to traces, or, alternatively, from matrix algebras with the usual trace. These sets are of interest in light of a theorem of E. Kirchberg about Connes' embedding problem.

Abstract Music has been found to be an instrument used in transforming lives because of its effectiveness as an agent and medium of transmitting information to the populace. It is used to pass crucial information, impart knowledge, soothe emotions, and affect lives. Music affects the ways and manner of its hearers positively and negatively, hence, it is expedient that people get right information through a good channel and medium. Music composers, performers and producers should be careful of what is composed and performed in order to achieve the desired result. This paper seeks to enlighten music composers and producers on the need to judiciously use music as an instrument of transformation in Africa and other world cultures. The use and effect of music on human being was traced from antiquity to date through library sources. It discovers that some of the recent music composition and performance in Nigeria and some other world cultures are not good enough for consumption. It recommends a viable music teacher education that will impart adequate knowledge on the music teacher trainee which will in turn transforms the music consumers.

Abstract Russian composer Sergei Prokofiev (1891-1953) and Sergei Diaghilev collaborated on three ballets (Chout, Pas d’Acier, Prodigal Son) for the Ballets Russes, and maintained a crucial personal and artistic relationship for fifteen years during a formative period in Prokofiev’s artistic life. This article traces their collaboration on the three ballets, and the production history of each.

Full textAbstract:
In this paper we present initial results of applying Time-Reversed Acoustics (TRA) technology to salt-dome flank, seismic imaging. We created a set of synthetic traces representing a multilevel, walkaway VSP for a model composed of a simplified Gulf of Mexico vertical-velocity gradient and an embedded salt dome. We first applied the concepts of TRA to the synthetic traces to create a set of redatummed traces without having to perform velocity analysis, moveout corrections, or complicated processing. Each redatummed trace approximates the output of a zero-offset, downhole source and receiver pair. To produce the final salt-dome flank image, we then applied conventional, poststack, depth migration to the zero-offset section. Our results show a very good image of the salt when compared to an image derived using data from a downhole, zero-offset source and receiver pairs. The simplicity of our TRA implementation provides a virtually automated method to estimate a zero-offset, seismic section as if it had been collected from the reference frame of the borehole containing the VSP survey.
