Full Text Available In the miscelies studied, molar volume and molar refraction values show linear dependence with the molar fraction of methyl stearate. Viscosity values fit Hildebrand's modified equation, where the "V_o" parameter is a linear function of the molar fraction of methyl stearate. Regarding with this three physico-chemical properties, the mixtures studied behave like ideal mixtures of two organic liquids without ionization.

En todas las miscelas estudiadas los valores del volumen molar y de la refracción molar presentan variaciones lineales en función de la fracción molar de estearato de metilo. Los valores de viscosidad de las miscelas estudiadas se ajustan a la ecuación de fluidez de Hildebrand modificada, siendo su parámetro "V_o" función lineal de la fracción molar de estearato de metilo. En relación con estas tres características, el comportamiento de las miscelas estudiadas no difiere significativamente del correspondiente a una mezcla "ideal" de dos líquidos orgánicos sin ionizar.

PREFACE: Symmetries in Science XIV

Symmetries Logo This volume of the proceedings "Symmetries in Science XIV" is dedicated to the memory of our colleagues and dear friends Marcos Moshinsky and Yuriĭ Smirnov who regularly participated in these Symposia and were a great inspiration to many. We shall miss them. Dieter Schuch and Michael Ramek The international symposium "Symmetries in Science XIV" held at Collegium Mehrerau in Bregenz, Austria from July 19-24, 2009, attended by 32 scientists from 11 countries, was an experiment, performed by theoreticians. Aim of this experiment was to find out if the desire to revive or even continue this conference series was stronger than the very restricted pecuniary boundary conditions. It obviously was! After its establishment by Bruno Gruber in 1979, the biennial series settled in the very stimulating atmosphere of the monastery Mehrerau, which provided the ideal environment for a limited number of invited participants to exchange ideas, without parallel sessions, and pursue deeper discussions (at the latest in the evening at "Gasthof Lamm"). When the conference series terminated in 2003, former participants were quite disappointed. Meeting again at several (larger) conferences in subsequent years, there were repeated expressions of "the lack of a Bregenz-type meeting in our field nowadays" and the question of a possible "revitalization", even without external funding. After some hesitation, but also driven by our own desire to reinstate the series, we consulted Bruno who not only approved wholeheartedly but also offered his full support. It all finally led to the symposium in July 2009. The atmosphere was really like in the "good old days" and the interesting and thought-provoking presentations culminated in the publication of these Proceedings. We are grateful to Carl Bender for establishing contact with IOP making it possible for us to publish these Proceedings in the Journal of Physics Conference Series. A majority of the participants contributed to these

2010-01-01

Since recently, arXiv offers a new submission interface implementing SWORD. SWORD is a brand new protocol that defines a simple way to deposit digital document on web repositories. The most part of digital documents submitted on Invenio are also deposited on arXiv. For this reason, it is a relevant added value for Invenio to offers such an automated “Forward to ArXiv” option to its users. The aim of this project is then to analyse, design and implements a library oriented SWORD client module (BibSword). This module will offer an user interface and will be integrated in the Invenio submission process.

The tensile and scaffolding properties of skin rely on the complex extracellular matrix (ECM) that surrounds cells, vasculature, nerves, and adnexus structures and supports the epidermis. In the skin, collagen I fibrils are the major structural component of the dermal ECM, decorated by proteoglycans and by fibril-associated collagens with interrupted triple helices such as collagens XII and XIV. Here we show that the cartilage oligomeric matrix protein (COMP), an abundant component of cartilage ECM, is expressed in healthy human skin. COMP expression is detected in the dermal compartment of skin and in cultured fibroblasts, whereas epidermis and HaCaT cells are negative. In addition to binding collagen I, COMP binds to collagens XII and XIV via their C-terminal collagenous domains. All three proteins codistribute in a characteristic narrow zone in the superficial papillary dermis of healthy human skin. Ultrastructural analysis by immunogold labeling confirmed colocalization and further revealed the presence of COMP along with collagens XII and XIV in anchoring plaques. On the basis of these observations, we postulate that COMP functions as an adapter protein in human skin, similar to its function in cartilage ECM, by organizing collagen I fibrils into a suprastructure, mainly in the vicinity of anchoring plaques that stabilize the cohesion between the upper dermis and the basement membrane zone.

Full Text Available Measurements of molar volume, refraction index and dynamic viscosity in mixtures of fatty acids or triglycerides and trichloroethylene, tetrachloroethylene and hexane were realized. Temperature range studied was 278-313 K each 5 K. The relationship between molar volume and molar fraction show high correlation coefficient In fatty acids with trichloroethylene and tetrachloroethylene mixtures. On the other hand, hexane mixtures show little contractions of molar volume at low molar fractions. Triglyceride mixtures present important deviations with regard to the ideality of the molar volume. The adjusts obtained for the molar volume values versus temperature are acceptable, calculating the coefficients of thermal expansion of the studied mixtures. Equally, the adjust of the experimental results of viscosity for two prediction equations are studied: one of additive type and the other of parabolic type.

Se han realizado medidas del volumen molar, índice de refracción y viscosidad dinámica en el intervalo de temperatura de 278 K a 313 K cada 5 K, a mezclas de ácidos grasos o triglicéridos con tricloroetileno, tetracloroetileno y hexano. Las mezclas de ácidos grasos con tricloroetileno y tetracloroetileno, presentan unos altos coeficientes de correlación para los valores del volumen molar frente a la fracción molar, mientras que las mezclas con hexano, a fracciones molares bajas, manifiestan una pequeña contracción del volumen molar. Las mezclas de triglicéridos presentan importantes desviaciones con respecto a la Idealidad del volumen molar. Los ajustes obtenidos para los valores del volumen molar frente a la temperatura son aceptables, determinándose los valores del coeficiente de dilatación volumétrica a presión constante de las mezclas estudiadas. Igualmente se ha estudiado el ajuste de los resultados experimentales de viscosidad a dos ecuaciones de predicción: una del tipo aditiva y otra del tipo parabólico.

1992-12-01

Full Text Available Values of molar refraction for every studied mixtures show linear plots versus molar fractions of triglyceride. Values of molar volume show this behaviour, but only for tributyrin-butanol or tricaprylin-butanol miscellas. However, in tributyrin-ethanol mixtures, volume contractions have been found, whereas triacetin-butanol and tributyrin-hexanol show volume expansions. These facts are related to the mode of being structured of the alcohol and triglyceride molecules in mixtures. A linear relationship between molar volume and temperature have been found, and also a linear dependence between the coefficient of thermal expansion at constant pressure and the molar fraction of triglyceride.

Los valores de la refracción molar en todas las miscelas estudiadas presentan variaciones lineales frente a la fracción molar de triglicérido. la misma variación que presentan los valores del volumen molar de las miscelas tributirina y tricaprilina en butanol. Sin embargo, en las miscelas de tributirina-etanol se encuentran contracciones de volumen mientras que en las de triacetina-butanol y tributirina-hexanol expansiones, atribuidas en ambos casos a la forma de estructurarse las moléculas de alcohol y triglicérido en las miscelas. Por otra parte, se encuentra una variación lineal entre el volumen molar de las miscelas y la temperatura, y se establece una relación lineal entre el coeficiente de dilatación térmico molar a presión constante y la fracción molar de triglicérido en los cinco sistemas estudiados.

[The disgrace of Antoine Daquin, first physician of Louis XIV (1693)].

Science.gov (United States)

Peumery, J J

1996-12-01

Antoine Daquin, Principal Physician of Louis XIV and Earl of Jouy-en-Josas, was born in Paris. He was the son of Louis-Henri Daquin, Physician to Queen Marie de Médicis; his paternal grandfather, born in the Jewish religion, became converted to catholicism at Aquino, in Italy, whence his name d'Aquin, then Daquin. A. Daquin studied to be a doctor at Montpellier and graduated on 18 May 1648. He married Marguerite Gayant, Antoine Vallot's niece, Antoine Vallot being the Principal Physician of Louis XIV. This relationship permitted him to get the position of Principal Physician of the Queen, then, after Vallot's death, to succeed him, on 18 April 1672, as Principal Physician of the King. The kindliness of the King's mistress, Mme de Montespan, helped him in that appointment. Daquin was a good doctor, he turned out awkward: "great courtier, but rich, miser, grasping, wanting to establish his family anyway" said the Duc de Saint-Simon. He dared ask the King for the Archbishopric of Tours for his son: "it was the rock on which he broke up" said again Saint-Simon. On 2 November 1693, the comte de Pontchartrain came to his home by order of the King, to tell him, he was ordered to retire from Court without delay. It was forbidden him to come back or to write to the King. Guy-Crescent Fagon was designated "Premier Médecin" instead of him; but Fagon had worked at the undoing of Daquin, with a view to robbing him of his position, with the complicity of the King's new mistress, Mme de Maintenon. After his disgrace, Daquin retired probably to Moulins; he died obscurely in Vichy, on 17 May 1696. Today, Daquin is regarded as a victim of intrigues of Court, which explains his celebrity.

Pouvoir et religion à la chapelle royale de Versailles sous Louis XIV Power and religion at the royal chapel of Versailles under Louis XIV

Alexandre Maral

Full Text Available D’une manière peut‑être plus sensible que partout ailleurs, les objets et les insignes du pouvoir prennent une importance particulière dans le contexte du cérémonial liturgique de la religion catholique. À la chapelle royale de Versailles, la présence régulière du monarque et de sa cour complique encore la situation, d’autant que la desserte est assurée par deux corps distincts d’ecclésiastiques. Dépassant le simple cadre des préséances, Louis XIV a défini autour de sa personne royale un système rituel susceptible d’en manifester le caractère épiscopal dérivé du sacre. De même, l’enjeu juridictionnel représenté par la Chapelle royale se traduit par un jeu subtil d’attitudes, de gestes et de rites, chorégraphie sacrée qui accompagne et exprime les revendications des partisans et des adversaires de l’exemption du lieu de culte royal au regard du diocèse de Paris. Ce discours trouve un écho partiel dans le programme décoratif de la chapelle définitive du palais, achevée en 1710.Objects and symbols of power take on a particular importance in the liturgical ceremony of the Catholic Church, perhaps more so than in any other context. At the royal chapel of Versailles, the regular presence of the king and his court complicated the situation further, all the more so in that religious ceremony was administered by two distinct ecclesiastic bodies. Beyond the rules of precedence, Louis XIV had introduced around his royal persona a system of ritual that would manifest the episcopal identity conferred upon him by his coronation. Similarly, the jurisdictional authority represented by the royal chapel was conveyed in a subtle play of attitudes, gestures and rites, a symbolic choreography that accompanied and expressed the claims of the partisans and adversaries of the exemption of the royal place of worship with regard to the diocese of Paris. This stance was reflected in the decorative scheme of the palace�

2009-01-01

The paper CERN-PH-EP-2009-015 (arXiv:0903.4762) by A. Bagulya et al. violates standards of quality of work and scientific ethics on several counts. The paper contains assertions that contradict established detector physics. The paper falls short of proving the correctness of the authors' concepts and results. The paper ignores or quotes misleadingly pertinent published work. The paper ignores the fact that the authors' concepts and results have already been shown wrong in the published literature. The authors seem unaware that cross-section results from the 'HARP Collaboration' that are based on the paper's concepts and algorithms are in gross disagreement with the results of a second analysis of the same data, and with the results of other experiments.

Observations of Fe XIV Line Intensity Variations in the Solar Corona During the 21 August 2017 Solar Eclipse

2018-01-01

We present time- and spatially-resolved observations of the inner solar corona in the 5303 Å line of Fe XIV, taken during the 21 August 2017 solar eclipse from a field observing site in Crossville, TN. These observations are used to characterize the intensity variations in this coronal emission line, and to compare with oscillation predictions from models for heating the corona by magnetic wave dissipation.The observations were taken with two Explore Scientific ED 102CF 102 mm aperture triplet apochromatic refractors. One system used a DayStar custom-built 5 Å FWHM filter centered on the Fe XIV coronal spectral line and an Atik Titan camera for image collection. The setup produced images with a pixel size of 2.15 arcseconds (~1.5 Mm at the distance to the Sun), and a field of view of 1420 x 1060 arcseconds, covering approximately 20% of the entire solar limb centered near the emerging sunspot complex AR 2672. We obtained images with an exposure time of 0.22 seconds and a frame rate of 2.36 Hz, for a total of 361 images during totality.An identical, co-aligned telescope/camera system observed the same portion of the solar corona, but with a 100 Å FWHM Baader Planetarium solar continuum filter centered on a wavelength of 5400 Å. Images with an exposure time of 0.01 seconds were obtained with a frame rate of 4.05 Hz. These simultaneous observations are used as a control to monitor brightness variations not related to coronal line oscillations.

Full Text Available Las menas lateríticas cubanas se exponen, en forma de pilas, a la radiación solar y la convección del aire para reducirles el contenido de humedad mediante la implementación del proceso de secado solar natural. La confección de las pilas de minerales se basa en criterios empíricos y, en consecuencia, no se conoce el área de exposición de las mismas y el volumen de mineral expuesto al secado. En este artículo se establecen los modelos matemáticos que permiten calcular, de forma precisa, la longitud de la superficie lateral, la altura, el área de exposición y el volumen de las pilas de mineral, en función de las dimensiones de la superficie horizontal disponible para el secado y de dos propiedades del material: la granulometría y la humedad. Las ecuaciones matemáticas establecidas caracterizan a las pilas con simetría axial y secciones transversales semi-elípticas, hiperbólicas, parabólicas y triangulares. Se aplicaron los modelos obtenidos a un caso de estudio para una superficie horizontal disponible de 40 m de largo y 5 m de ancho, considerando los valores medios de los ángulos de reposo maximal y tangencial de las menas lateríticas cubanas.

Fine structure transitions in Fe XIV

Science.gov (United States)

Nahar, Sultana N.

2013-07-01

Results are reported for Fe XIV energy levels and transitions obtained from the ab initio relativistic Breit-Pauli R-matrix (BPRM) method. BPRM method developed under the Iron Project is capable of calculating very large number of fine structure energy levels and corresponding transitions. However, unlike in the atomic structure calculations, where levels are identified spectroscopically based on the leading percentage contributions of configurations, BPRM is incapable of such identification of the levels and hence the transitions. The main reason for it is that the percentage contributions can not be determined exactly from the large number of channels in the R-matrix space. The present report describes an identification method that uses considerations of quantum defects of channels, contributions of channel from outer regions, Hund's rule, and angular momenta algebra for addition and completeness of fine structure components. The present calculations are carried out using a close coupling wave function expansion that included 26 core excitations from configurations 2s22p63s2, 2s22p63s3p,2s22p63p2,2s22p63s3d, and 2s22p63p3d. A total of 1002 fine structure levels with n ⩽ 10, l⩽9, and 0.5 ⩽J⩽ 9.5 with even and odd parities and the corresponding 130,520 electric dipole allowed (E1) fine structure transitions, a most complete set for astrophysical modelings of spectral analysis and opacities, is presented. Large number of new energy levels are found and identified. The energies agree very well, mostly in less than 1% with the highest being 1.9%, with the 68 observed fine structure levels. While the high lying levels may have some uncertainty, an overall accuracy of energy levels should be within 10%. BPRM transitions have been benchmarked with the existing most accurate calculated transition probabilities with very good agreement for most cases. Based on the accuracy of the method and comparisons, most of the transitions can be rated with A (⩽10%) to C (�

Full Text Available The patterns of infracommunity descriptors (diversity, dominance, abundance are compared when calculated with the number and body volume of the parasites in a sample of 26 southern pomfrets Brama australis collected in the area off Talcahuano, Chile. No numerical infracommunity descriptor was correlated with its corresponding volumetric descriptor. This single result casts doubts about the general validity of the infracommunity patterns described in the literature so far, because they are almost exclusively based on the number of parasite individuals per individual host, restricting communication with ecologists that use density or other measures of ecological abundanceLos patrones de los descriptores infracomunitarios (diversidad, dominancia, abundancia son comparados cuando son calculados en base a los números o al volumen corporal de los parásitos en una muestra de 26 reinetas Brama australis recolectadas en el área de Talcahuano, Chile. Ningún descriptor infracomunitario calculado con el número de parásitos estuvo correlacionado con los basados en el volumen corporal de los parásitos. Este resultado siembra dudas acerca de la validez general que pueden tener los patrones infracomunitarios registrados en la literatura ya que están casi exclusivamente calculados con el número de parásitos por individuo hospedador, lo que dificulta aún más la comunicación con los ecólogos, que usan la densidad u otras medidas de abundancia ecológica

Full Text Available This paper presents a hypothesis about the order in the constructive process for the head zone in the Cathedral of Ávila, called Cimorro. The hypothesis proposed in this area considers for its construction three different stages: XII Century, XIII Century and XIV Century. The proposed hypotesis have been verified with the Analysis of Stability realised. The theoretical Framework used is the Limit Analysis to Masonry Structures. After prooving the Structural Stability for each of the building stages, the following conclusions are made: Through the XII Century, the possibility of closing the central vault without Buttress System for a short period of time and the subsequent placement of a tribune is stated. A fortification formed by the barbican and the «adarves» were built during the XIII Century. In the XIV Century, the tribune is removed and replaced with the Buttress System with buttress and double flying buttress, which we can see nowadays.

These are the legend of Placido (Placido is a Benedict's young disciple mentioned in the Dialogi, which has Sicily as a background, as recounted by Pietro, Deacon of Montecassino between the XI and the XII centuries, and the Sicilian vulgarization of the work, carried out by Giovanni Campolo in the first half of the XIV century. The literary voyage of Placido and the work of Campolo are two excellent examples of the circulation and the fruition of an exemplary and authoritative text. Each highlights the complex intricacy of religion, culture and politics in the various systems of power and in the various historical settings that the medieval age explored.

Full Text Available The French and Spanish courts were two of the most powerful cultural and political institutions in seventeenth-century Europe.  Both rivals and allies, the French and Spanish crowns were bound by disputes and diplomacy.  This anthology examines the Gallic and Iberian court systems from a comparative approach, filling an important lacuna in early modern political studies and diplomatic history.  It is based on the proceedings of a seminar held at the Casa de Velázquez, Madrid in June 2010. Edited by Daniel Aznar, Guillaume Hanotin and Niels F. May, À la place du roi. Vice-rois, gouverneurs et ambassadeurs dans les monarchies française et espanole (XVIe-XVIIIe siècles unites ten essays by leading scholars of seventeenth-century French and Spanish history.

Politica e censura nella Francia di Louis XIV: Chavigny de La Bretonnière

Directory of Open Access Journals (Sweden)

Chiara Mainardi

2012-06-01

Full Text Available During the reign of Louis XIV French libertines were expressing their intellectual dissent by opposing absolutism and criticising historical and religious conflicts. While in France, before abrogating the Edict of Nantes, any opposition was suppressed, Chavigny de La Bretonnière supported a revolt against the Church and political power. The prominent role of clandestine literature in Old Regime France will be analysed in this paper by considering critical studies about libertinage. In particular, the political and antireligious discourse carried on by this author will be highlighted by taking into account his ‘lardons’, satirical articles against French government, his erotic novel La Religieuse en chemise and his ecclesiastic pamphlet Le Cochon mitré. In a true editorial campaign, Chavigny de La Bretonnière attaches French royal power, through the use of satire he depicts corrupted prelates as obscene creatures and he reforms libertine dialogue by enhancing broad political purposes. As a response to his critics and claims, Chavigny was kidnapped, tortured and imprisoned for life. His name disappeared from history.

Full Text Available En el mundo se estima que hay alrededor de 7000 lenguas. De ellas, sólo algunas tienen el estatus de ser lenguas oficiales y otras, además, son lenguas internacionales. Muchas veces, el estatus de éstas está ligado a factores económicos o políticos. En otros casos, se debe a la herencia colonizadora. Aquellas lenguas que no gozan de un estatus alto, terminan por tener espacios limitados para su uso o por perecer si dejan de transmitirse a las generaciones subsecuentes de hablantes. Este fenómeno se da en todas las latitudes del mundo. En el caso particular de Nuestra América, podemos encontrar esta problemática con las lenguas indígenas y, aunque menos visible, pero con la misma importancia, con las lenguas criollas. Para los lectores de nuestra revista, en el Volumen 11 de esta publicación, presentamos una discusión variada sobre algunas prácticas de las lenguas y sus interacciones con otras. Hay estudios históricos sobre el poder subversivo y de resistencia de las lenguas indígenas, propuestas pedagógicas para mantenerlas y revitalizarlas, planteamientos estratégicos de descolonización del pensamiento y conocimiento, análisis de la relación entre lengua, poder e identidad, y reflexiones sobre la situación de otras lenguas que coexisten en ámbitos plurilingües como el criollo y las dificultades y prejuicios a los que se enfrentan por no tener un estatus alto.

2011-09-01

En este artículo se tratan aquellas patologías que ponen en peligro la vida del paciente y que precisan acciones terapéuticas inmediatas, como son la obstrucción de vía aérea, el neumotórax a tensión, el taponamiento cardiaco, neumotórax simple y neumotórax abierto. El shock, definido por un grado severo de hipoperfusión tisular, necesita ser corregido mediante una infusión adecuada de volumen incluyendo factores de coagulación para evitar el círculo vicioso de la llamada “tríada letal” que corresponde a hemorragia, hipotermia y coagulopatía, que a su vez perpetúa la hemorragia. La toracotomía de reanimación tiene indicaciones precisas y sus resultados dependen de la etiología del traumatismo, siendo mejor al utilizarse en lesiones penetrantes cardiacas y con el menor tiempo en que se efectúa.

O artigo analisa o conjunto de preprints submetidos às diferentes categorias FAE do repositório temático especializado arXiv no período 2010-2015 que foram posteriormente publicados em revistas peer review. Os indicadores bibliométricos demonstram a potencialidade dos preprints como canal precursor de difusão de resultados científicos visto que 70% das submissões foram em seguida absorvidas pelas principais revistas da FAE. Conclui que o êxito alcançado pelas iniciativas Open Access arXiv e INSPIRE-HEP favoreceu o intercâmbio de informações e conhecimentos entre os pesquisadores. O modelo proposto pela FAE pode incentivar cientistas de áreas com características similares a instalarem repositórios e bancos de dados de preprints para suas disciplinas com o intuito de fortalecer a comunicação das descobertas científicas.

Firstly, the estimates of standard deviation and arithmetic mean as basic statistical parameters are emphasised, which point out the variability and magnitude of annual streamflow records in the hydrological studies of planning water-resource developments inside a region. Then the equations for quantitative evaluations of statistical convenience of extending a short stream flow record are described in detail. The previous makes use of additional and common data in one or two closer hydrometric stations, with this the short observed record has a certain correlation (dependence or association). Later two numerical applications to real problems are given, the first one for the two dimensional model, which uses a closed hydrometric station in order to extend the short record, and the second application for the three dimensional model which makes use of two auxiliary hydrometric stations. Lastly, three general observations about the paper are cited. [Spanish] Inicialmente se destaca la importancia de las estimaciones de la medida y la desviacion estandar como parametros estadisticos basicos, los cuales caracterizan la magnitud y la variabilidad de los volumenes escurridos anuales en los estudios hidrologicos de planeacion del aprovechamiento de los recursos hidraulicos de una region. Enseguida, se describen con detalle las ecuaciones que permiten evaluar cuantitativamente si es conveniente o no, desde un punto de vista estadistico, ampliar el registro corto de escurrimientos, con base en datos comunes, adicionales y disponibles; esto en una o dos estaciones hidrometricas cercanas, con las cuales, el registro reducido guarda cierta correlacion (dependencia o asociacion). Lo anterior, significa evaluar si con base en el registro ampliado, las estimaciones de la medida y la variancia mejoran estadisticamente. Posteriormente, se realizan dos aplicaciones numericas a casos reales; una, para el modelo bidimensional que utiliza una estacion hidrometrica cercana para ampliar el

Brigitta obtuvo la mayor altura del brote en tratamientos con densidades y volúmenes elevados, mientras que Legacy obtuvo el mayor promedio de altura del brote con densidades intermedias y volúmenes elevados. En cuanto al número de brotes/explante, el volumen de medio no influyó en la variedad Brigitta, en cambio, altas densidades la afectaron significativamente, mientras que en Legacy el máximo número de brotes se alcanzó con densidades bajas y volúmenes intermedios. En relación al número de nudos por explante Brigitta obtuvo los valores más bajos comparados con Legacy, pero en ambas variedades se produjo una disminución del número de nudos con menores volúmenes de medio. Para el número de brotes por frasco Brigitta obtuvo las mayores respuestas con densidades elevadas, superando los 40 brotes por frasco. En cambio, en Legacy el resultado máximo se obtuvo con la densidad 25 explantes en 30 mL de medio. Por lo tanto, se concluye que ambas variedades fueron influenciadas tanto por el volumen del medio como la densidad de explantes.

PREFACE: XIV Mexican School on Particles and Fields

2011-03-01

The XIV Mexican School on Particles and Fields took place from 8-12 November, 2010, in the colonial city of Morelia, Michoacan, Mexico. The format of the school was such that the morning sessions were devoted to theoretical and experimental reviews, whereas parallel thematic sessions were held in the afternoons. All the reviews and seminars were delivered by experts of international prestige on subjects which are of current interest to the global scientific community and are also actively pursued within Mexico. In order to equip the attending graduate students and post docs with the necessary introductory tools to allow them to benefit substantially from the specialized seminars, a series of mini-courses were offered prior to the event from 4-7 November 2010, in the Auditorium of the Faculty of Science of the University of Michoacan (UMSNH). The length of each course was about 5 hours, English being the language of instruction. An informal and friendly atmosphere was encouraged during the courses so that the students could overcome their inhibitions and actively participate in the discussions. A novel feature of this event was a colloquium aimed at the general public and younger students of pre-undergraduate level, which allowed the expert scientists to reach out to a wider community and raise their awareness and interest in one of the most fascinating and vital fields of knowledge. The XIV-MSPF was organized by the Division of Particles and Fields of the Mexican Physical Society. It was generously sponsored by several institutions: Consejo Estatal de Ciencia y Tecnológico (COECyT) del Estado de Michoacán, Universidad Michoacana de San Nicolás de Hidalgo, Universidad de Sonora, Universidad Nacional Autónoma de México, Universidad de Guanajuato, Universidad de Sinaloa, Centro de Investigaciones de Estudios Avanzados del IPN (CINVESTAV), Consejo Nacional de Ciencia y Tecnología (CONACyT), la Academia Mexicana de Ciencias and, most importantly, the Red Nacional

Cette tradition de luxuriance se traduit à l’âge d'or bourguignon par une efflorescence de couleurs sur les édifices qui durera jusqu’à la prise de Lille par Louis XIV en 1667.

Le style franco‑lillois transmettra ce goût pour la couleur à travers la reconstitution du centre ville au xviie siècle, ce dont témoigne le plan-relief de 1743.

The reinforced alloy presents a yield strength of 1300 MPa at room temperature with respect to 800 MPa for the un-reinforced material. After heat treatment, the yield strength of both alloys does not change significantly. However, a decrease in ductility and ultimate tensile strength have been observed

En este trabajo se estudia la influencia de la adición de un 10 % en volumen, de cromo en las propiedades mecánicas de aleaciones Ni₃Al-Cr procesadas por vía pulvimetalúrgica. Para ello se prepararon dos aleaciones: la primera, se obtuvo por molienda de polvo de composición Ni-20,9Al-8Cr-0,49B (% at. y, a la segunda, se le añadió un 10 % en volumen de partículas de cromo, mediante un proceso de mezcla, previo al de molienda. Ambas, fueron consolidadas mediante compactación isostática en caliente (HIP y, por último, se les aplicaron tratamientos térmicos para homogeneizar la microestructura. Los resultados experimentales han mostrado que el refuerzo de cromo tiene como efecto un importante aumento del límite elástico y de la resistencia. Así, el material reforzado presenta un límite elástico cercano a 1.300 MPa, a temperatura ambiente, frente a los 800 MPa que presenta el material sin reforzar, a la misma temperatura. En relación con las propiedades mecánicas de los materiales tratados térmicamente, se observa que ambos experimentan un acusado

The soil vulnerability determines the sensitivity of the soil after an accidental radioactive contamination due to Cs-137 and Sr-90. The Departamento de Impacto Ambiental de la Energia of CIEMAT is carrying out an assessment of the radiological vulnerability of the different Spanish soils found on the Iberian Peninsula. This requires the knowledge of the soil properties for the various types of existing soils. In order to achieve this aim, a bibliographical compilation of soil profiles has been made to characterize the different soil types and create a database of their properties. Depending on the year of publication and the type of documentary source, the information compiled from the available bibliography is very heterogeneous. Therefore, an important effort has been made to normalize and process the information prior to its incorporation to the database. This volume presents the criteria applied to normalize and process the data as well as the soil properties of the various soil types belonging to the provinces of Guadalajara, Cuenca and Albacete of the Comunidad Autonoma de Castilla-La Mancha.

Full Text Available En 1878 Villa-Amil y Castro publicó el primer catálogo impreso de los manuscritos procedentes del Colegio de San Ildefonso de la Universidad de Alcalá de Henares. Para su trabajo Villa-Amil dependió estrechamente de las catalogaciones efectuadas antes en 1745 y de nuevo en 1800. Recientemente, Paul Oskar Kristeller ha puesto su atención en los manuscritos humanistas de esta colección; la cual es esencial para el estudio del humanismo en la universidad hispana del Renacimiento temprano. Desde este punto de vista se hace necesaria una nueva catalogación de los manuscritos del Colegio de San Ildefonso. Por ejemplo, el volumen facticio MSS 133 contiene once manuscritos de mediados del siglo XV entre los cuales se conserva el único testimonio de una de las obras latinas de Alfonso de Palencia. El objeto de este trabajo es una descripción bibliográfica más detallada de estos once manuscritos encuadernados en UCM BH MSS 133. In 1878 Villa-Amil y Castro published the first printed catalogue of the manuscript collection of the old Colegio de San Ildefonso at the University of Alcalá de Henares. In his work Villa-Amil followed closely the catalogues produced earlier in 1745 and again in 1800. More recently, Paul Oskar Kristeller has focused his interest on the humanistic manuscripts of this collection, as this library becomes essential in the study of humanism in the hispanic universities during the early Renaissance. From this point of view it is necessary a closer examination to the manuscripts belonging to the old Colegio de San Ildefonso. For example, volume MSS 133 contains eleven manuscritpts from the mid 15th century among them a unique testimony of a Latin composition by Alfonso de Palencia. The object of this paper is a more detailed bibliographical description of these eleven manuscripts in UCM BH MSS 133.

In NSRR (Nuclear Safety Research Reactor) experiments, test fuels are inserted in the especial capsule and the capsule will be inserted into the experimental tube which is located in the center of reactor core. In NSRR, there are 17 types of atmospheric pressure capsule, and one of them Type X-IV atmospheric pressure capsule has been produced 6 times under authorization of Ministry of Education, Culture, Sports, Science and Technology (MEXT). Application for the 7th time of authorization was submitted to the MEXT in June 2006. On this application, standard which is used to design was changed to The Japan Society of Mechanical Engineers (JSME) S NC1-2005 from the Notification 501 of the Ministry of Economy, Trade and Industry (METI). The JSME S NC1-2005 introduced the service condition in addition to the reactor condition which has been used in the Notification 501. In this application, stress limits were calculated based on the service condition. The JSME S NC1-2005 requires estimation of combined stress for Class1 support structures, which was unnecessary in the Notification 501. In this application, combined stresses were calculated and confirmed not to exceed the stress limits. (author)

Full Text Available Background and aims: there is little scientific evidence on the outcomes of endoscopic retrograde cholangiopancreatography (ERCP performed in low-volume hospitals; however, in our country, it is growing up its implementation. The objectives of our study were to evaluate the efficacy and safety of this technique performed by two endoscopists with basic training in a center of this nature and analyze the learning curve in the first procedures. Patients and methods: single-center retrospective study of the first 200 ERCP performed in our hospital (analyzing the evolution between the first 100 and 100 following procedures, comparing them with the quality standards proposed in the literature. Results: from February 2009 to April 2011, we performed 200 ERCP in 169 patients, and the most common indications were: Choledocholithiasis (77 %, tumors (14.5 % and other conditions (8.5 %. The cannulation rate rose from 85 % in the first 100 ERCP to 89 % in the next 100 procedures, clinical success from 81 % to 87 %, decreasing the post-ERCP acute pancreatitis rate from 11 % to 4 %, upper gastrointestinal bleeding (UGIB from 3 % to 2 % and acute cholangitis from 4 % to 1 %. There was a death from a massive UGIB in a cirrhotic patient in the first group of patients and a case of biliary perforation resolved by surgery in the second one. Conclusions: the results obtained after performing 200 procedures support the ability to practice ERCP in low-volume hospitals obtaining levels of efficacy and safety in accordance with published quality standards.Introducción y objetivos: existe poca evidencia científica sobre los resultados de la CPRE realizada en hospitales con bajo volumen, sin embargo su puesta en marcha en nuestro medio es creciente.

How does the data collection XIV-XV of the European Society of Human Reproduction and Embryology (ESHRE) PGD Consortium compare with the cumulative data for data collections I-XIII? The 14th and 15th retrospective collection represents valuable data on PGD/PGS cycles, pregnancies and children: the main trend observed is the increased application of array technology at the cost of FISH testing in PGS cycles and in PGD cycles for chromosomal abnormalities. Since 1999, the PGD Consortium has collected, analysed and published 13 previous data sets and an overview of the first 10 years of data collections. Data were collected from each participating centre using a FileMaker Pro database (versions 5-12). Separate predesigned FileMaker Pro files were used for the cycles, pregnancies and baby records. The study documented cycles performed during the calendar years 2011 and 2012 and follow-up of the pregnancies and babies born which resulted from these cycles (until October 2013). Data were submitted by 71 centres (full PGD Consortium members). Records with incomplete or inconsistent data were excluded from the calculations. Corrections, calculations and tables were made by expert co-authors. For data collection XIV-XV, 71 centres reported data for 11 637 cycles with oocyte retrieval (OR), along with details of the follow-up on 2147 pregnancies and 1755 babies born. A total of 1953 cycles to OR were reported for chromosomal abnormalities, 144 cycles to OR for sexing for X-linked diseases, 3445 cycles to OR for monogenic diseases, 6095 cycles to OR for PGS and 38 cycles to OR for social sexing. From 2010 until 2012, the use of arrays for genetic testing increased from 4% to 20% in PGS and from 6% to 13% in PGD cycles for chromosomal abnormalities; the uptake of biopsy at the blastocyst stage (from cycles for structural chromosomal abnormalities, alongside the application of array comparative genomic hybridization. The findings apply to the 71 participating centres and may

Full Text Available AbstractThe Thermal Lag Engine (TLE patented by Peter Tailer’s is briefly introduced. The discussion about the thermodynamic working principle of this external combustion machine is presented. For this work the claims in literature have been studied by the authors to design and develop an experimental installation with the objective of measuring for the first time the pressure-volume (pV relationship of a TLE asdescribed by Tailer and West. The pV diagrams are presented here and support previous theoretical claims about the TLE. Their triangular form shows the effects described by West in the expansion and compression processes caused by the variation of the cold heat transfer area. Also the relationshipbetween the heat transfer capacity of the engine and its working frequency becomes apparent from the measurements, indicating that larger heater areas and limited cold heat transfer characteristics allow more work production per cycle at higher operating frequencies.Key words: thermal lag engine, pressure-volume diagrams, external combustion engines._______________________________________________________________________________ResumenSe introduce brevemente el Motor de Lag Térmico (MLT patentado por Peter Tailer y se esboza el debate científico sobre la termodinámica de esta máquina de combustión externa.

The Mexican Workshop on Particles and Fields (MWPF) is a biennial meeting organized by the Division of Particles and Fields of the Mexican Physical Society designed to gather specialists in different areas of high energy physics to discuss the latest developments in the field. The fourteenth edition of this meeting was held from November 25 to 29, 2013, at the colonial city of Oaxaca de Juárez, Oaxaca, Mexico. The XIV Mexican Workshop on Particles and Fields consisted of invited lectures, discussion and poster sessions. Experimental and theoretical developments were presented by distinguished physicists, addressing the most recent results in the field. The invited review talks included topics on collider physics, neutrino physics, physics beyond the Standard Model, flavor and hadronic physics, astroparticle physics, dark matter physics and effective theories, among others. The highlight topic of the conference was the presentation of the most resent results from the most popular high energy experiments in the world. The discovery of a particle consistent with the long-sought Higgs boson, considered one of the most important discoveries of the 21st century, was fully addressed by José Benítez and Kirill Prokofiev from CERN. The overview of the results of ALICE on the first run of the LHC was extensivly covered by Antonio Ortiz, from Lund University, and Daniel Tapia, from Universití Paris-Sud. The prospects and status of the new Belle II experiment were presented by Yoshi Sakai from KEK. The plans and projects of Tevatron on the new era of accelerators were explained by Gene Fisk from FERMILAB. Eric Vázquez from SNOLAB presented a wonderful explanation about the Dark Matter detection and the most resent results about the searches for it. The largest high energy cosmic rays detector, the Pierre Auger, was presented by Luis Villasñnor from University of Michoacán. On Friday 29th of November, we had an excursion to the archeological site of Mitla and to Santa

Purpose: The object of this study was to determine the extent to which a new volume-artifact reduction (VAR) modality using helical CT was able to reduce artifacts in the anterior, middle and posterior fossae in comparison with conventional CT (sequential mode). Methods: In a prospective, randomized trial, 50 patients underwent helical CT (VAR) and 50 underwent sequential CT. The results were evaluated by three radiologists; influences on image quality where scaled between 1 (no artifact) and 4 (not assessable). Eight regions of the anterior, middle and posterior fossae were evaluated. Results: On average, artifacts were scaled at 2.5 in helical CT (VAR) and 3.1 in conventional CT. Significant differences were seen at the eyeball, anterior to the petrosol bone, at the internal occipital crest, and at the level of the transverse sinus (p<0.005). Conclusions: Helical CT with the VAR modality is superior to conventional, sequential CT in the area of the anterior, middle and posterior fossae. (orig.) [German] Ziel: Das Ziel dieser Studie war herauszufinden, inwieweit ein neuer Volumen-Artefakt-Reduktionsmodus (VAR) im Spiral-CT in der vorderen, mittleren und hinteren Schaedelgrube gegenueber der Einzelschicht-CT zu einer Artefaktverringerung beitragen kann. Methoden: In einer prospektiven randomisierten Studie wurden 50 Untersuchungen mit Spiral-CT und 50 mit Einzelschicht-CT bezueglich Artefakten verglichen. Die Auswertung erfolgte durch drei Radiologen, die Bildqualitaet wurde in einer Skala zwischen 1 (kein Artefakt) und 4 (Beurteilung der Region wegen Artefakten nicht moeglich) angegeben. Acht anatomische Regionen in der vorderen, mittleren und hinteren Schaedelgrube wurden auf Beeintraechtigung durch Artefakte untersucht. Ergebnisse: Im Durchschnitt betrug die Bewertung fuer die Artefaktbeeintraechtigung beim Spiral-CT (VAR) 2,5 gegenueber 3,1 bei der Einzelschicht-CT.

Full Text Available The issue of this article is the patronage or promotion of de chapels in gothic churches as a mean of consolidation of people's social prestige. All along the XIV century the cathedral and the three parishes of Sta. Maria del Mar, Sta. Maria del Pi and Sant Just in Barcelona had been rebuilt. Church authorities had expected that changuig the romanic churches into the the gothic style known today would be slow and expensive, that is why they decided to confer the new chapels to wealthy people who in turn were supposed to give the eclesiastical institution a generous donation. The promotors of these chapels were mostly merchants and royal civil servants who were at that time in the best social position. Most of them belonged to families who had achieved this position in the past, but we have concentrated in those who were the last ones to obtain better standards of social consideration. The monitoring of their social development has been done thoug legal documentation.

El tema d'aquest article es el mecenatge o promoció de capelles a les esglésies gòtiques corn a instrument de consolidació del prestigi social. Al llarg del segle XIV es van renovar la catedral i les tres grans esglésies parroquials de Barcelona: Sta. Maria del Mar, Sta. Maria del Pi i Sant Just. Les autoritats eclesiàstiques van preveure, des del principi, que la transformació d'aquells temples romànics en els gòtics de l'actualitat seria lenta i molt cara. Per això van decidir concedir les noves capelles que s'anaven construint a persones adinerades, a canvi que paguessin un generós donatiu. Els promotors d'aquelles capelles eren, majoritàriament, mercaders i oficials reials, els sectors socials que mes van prosperar en aquell context. Bona part d'aquells promotors pertanyia a famílies que ja havien iniciat l'escalada estamental anteriorment, però nosaltres ens hem centrat en els que van protagonitzar nous ascensos socials.

Full Text Available This article examines the questie/ subsidies requested by the Catalan- Aragonese monarchs from the towns of the royal domain of Catalonia between 1309 and 1359. From the point of view of the Crown, the importance of these tributes lies in the fact that they were the monarchy’s main way of financing prior to the transcendental changes in taxation of the decades of 1350 and 1360. And, from the point of view of the towns, the necessity to negotiate with the king and his officials, year after year, the amount of the questie/subsidies due in every small city, contributed to the increasing financial autonomy of the municipalities and, beyond that, to the social and institutional coordination of that community.

En este artículo se estudian las questie/subsidios pedidas por los monarcas catalanoaragoneses a las villas de realengo de Cataluña entre 1309 y 1359. Desde el punto de vista de la Corona, la importancia de estos tributos radica en que fueron la principal forma de financiación de la monarquía antes de las trascendentales transformaciones fiscales de las décadas de 1350 y 1360. Y, desde la perspectiva de las villas, la necesidad de negociar con el rey y sus oficiales, año por año, el volumen de las questie/subsidios a pagar por cada pequeña ciudad contribuyó a la creciente autonomía financiera de los municipios y, más allá, a la vertebración social e institucional de la propia comunidad.

Full Text Available Before becoming a customs duty, the almojarifazgo consisted of a set of heterogeneous income received by the Castilian monarchs. Originally, most of these rents were demanded by the Muslim rulers of the cities then conquered by the Christian kings. However, during the thirteenth and fourteenth centuries the kings were giving them to the lords and local councils and kept for themselves the most interesting of all, the customs duty. The kingdom of Murcia is almost the only example to study how this transformation because it is the only territory that has retained suffi cient documentation to analyse it.

Antes de convertirse en un impuesto aduanero, el almojarifazgo consistió en un conjunto de rentas heterogéneas percibidas por los monarcas castellanos. En origen, la mayor parte de esas rentas fueron demandadas por los gobernantes musulmanes de las ciudades luego conquistadas por los reyes cristianos. Sin embargo, durante los siglos XIII y XIV dichos reyes las fueron cediendo a los señores y concejos locales y se quedaron con la más interesante de todas, el arancel aduanero. El reino de Murcia constituye casi el único ejemplo para estudiar cómo se operó esta transformación, porque es el único territorio que ha conservado la sufi ciente documentación para poder analizar tal transformación.

He gives account of the importance attained by the export of cattle, fish and corn from Castile to Aragón. And on the other side he proves that foodstuffss played a minor role in the exports from the Crown of Aragón to the Crown of Castile, though spices, wine and oil, among other foodstuffs, were exported to Castile from the territories of the Crown of Aragón.

En este artículo el autor analiza el comercio de exportación de los productos alimentarios entre los territorios de la Corona de Castilla y los de la Corona de Aragón, durante los siglos XIV y XV, tanto por vía terrestre como por vía marítima. Subraya la importancia que alcanzó la exportación de ganado, pescado y cereales desde la Corona de Castilla a la Corona de Aragón. Como contrapartida, el autor demuestra que los productos de alimentación no tenían tanta importancia dentro de las exportaciones efectuadas desde la Corona de Aragón a la Corona de Castilla, si bien las especias, el vino y el aceite fueron objeto de exportación desde la Corona de Aragón a Castilla.

To retrospectively evaluate the performance of two water-equivalent oral contrast agents [locust bean gum (LBG)-mannitol and VoLumen] concerning their potential to distend the bowel while avoiding contrast-associated artifacts in PET/computed tomography. PET/computed tomography examinations of 30 patients with two different oral contrast agents were reviewed. Bowel distension, intraluminal density, and potential contrast-associated artifacts were assessed for stomach, jejunum, and ileum. Statistical significance was tested by Student's t-test. Distension was slightly better in the stomach with VoLumen as compared with LBG-mannitol whereas LBG-mannitol was found to slightly better distend the small bowel. This difference proved to be statistically significant for the jejunum. A statistically significant difference was detected for intraluminal density with higher densities for VoLumen. This difference, however, did not result in a higher incidence of PET artifacts with VoLumen. LBG-mannitol provides excellent bowel distension, thereby avoiding contrast-associated PET artifacts. If this solution is not available, VoLumen provides a satisfactory alternative for bowel distension without relevant PET artifacts.

Full Text Available The results of technological research of silk fabrics from the noble-born woman grave from Bolgar, which was made in the period of the Golden Horde are represented in the article. The burial has been found in the ruins of the mausoleum, which is dated from the end of the XIV century. The deviation from the Islamic traditions is regarded as peculiarity of this burial. There were found clothes from silk, which was decorated by golden threads and the temple rings. The object of study is a well-preserved complex headdress, which includes several textile layers, such kinds of the silk products of various kinds: shawls, scarves, veilings. That sort of headdress has analogues in ethnographic materials in Central Asia. Microscopy has been used to determine the species composition of the fabrics: there were considered the structure of textile weaves, technology for manufacturing threads, in polychrome fabrics - colour selection of the threads. The samples of medieval fabrics, such as lance, taffeta, summit and others have been identified. During the restoration of the veiling the method of stabilizing the object has been used, which combines the strengthening of the gold threads and plasticization of the archaeological fabrics. Golden embroidery pattern has been also recovered. The enhanced diversity indicates on developed trading system with various sources of imports - from China, Central Asia, Egypt.

The incorporation of computer aided teaching technologies increases the efficiency in the transmission and acquisition of knowledge, allowing the handling of large information volumes, the knowledge homogenization among the students, the availability, the massive teaching and the permanent updating of the same. On the other hand, considering that all energy saving policy must be supported in a training and dissemination program of the respective energy technologies an immediate option is the use of computerized systems of teaching-learning. Precisely, in this paper, are presented the fundamental technical aspects for the development of a tutorial expert system, to aid the training in energy cogeneration, trying to integrate in the application, the usage of multimedia tools with the intelligent handling of the teaching-learning process through the inference machine of an expert system.

Our purpose was to assess the performance of a new combination of neutral oral contrast for CT abdomen and CT Enterography in comparison with commercially available neutral oral contrast VoLumen. Seventy three consecutive patients were given sorbitol/CMC (Carboxy Methyl Cellulose) solution or VoLumen as oral contrast agent for abdominal computed tomography (CT) scan. 23 patients were male and 37 females. Age range was between 16 and 67 years. Since the use of CT scan for abdominal pathologies, there was need to separate bowel loops to localize the pathology. Three types of oral contrast can be used in CT-Scan abdomen; Positive, Neutral and negative. The above used contrasts are Neutral contrast these refers to agents that have an attenuation value similar to that of water (0-30 H).Our results show this new combination of Cc and Sorbitol to be equally good as VoLumen, for luminal distension and mural details, in duodenum and jejunum. While better than VoLumen for Ileal distension. (author)

Images of three animal cadaver hips, 8 dissected patient femoral heads and 18 hip joints of human corpses, all either with arthrosis stage I-III or artificial cartilage defects, were compared with their corresponding anatomic sections. Additional histomorphologic examinations of the arthrotic cartilages were conducted, and MR-Imaging of 20 healthy and 21 arthrotic patient hips was performed using a specific traction method. Using a T{sub 1}-weighted 3-dimensional gradient-echo sequence and a traction of the hip joint, it was possible due to the low-signal imaging of the joint space to separate in vivo the high-signal femoral head cartilage from the high-signal acetabular cartilage. In horizontal position of the phase-encoding parameter, minimisation of the chemical-shift artifact, mainly in the ventro-lateral areas, was accomplished. MRI measurements of the articular cartilage widths showed significant correlations (p < 0.001) with the corresponding anatomic sections. At the same time the T{sub 1} 3-dimensional gradient-echo sequence of the lateral femoral head with r = 0.94 showed the lowest deviations of the measurements. It was possible with MR-Imaging to distinguish four cartilage qualities.

We report the amino acid sequence of 13 open reading frames (ORF > 299 bp) located on a 21.7 kb DNA segment from the left arm of chromosome XIV of Saccharomyces cerevisiae. Five open reading frames had been entirely or partially sequenced previously: WHI3, GCR2, SPX19, SPX18 and a heat shock gene similar to SSB1. The products of 8 other ORFs are new putative proteins among which N1394 is probably a membrane protein. N1346 contains a leucine zipper pattern and the corresponding ORF presents an HAP (global regulator of respiratory genes) upstream activating sequence in the promoting region. N1386 shares homologies with the DNA structure-specific recognition protein family SSRPs and the corresponding ORF is preceded by an MCB (MluI cell cycle box) upstream activating factor.

A finite vomume method for calculation of steady and unsteady flow on unstructured grids is parallelized by local spatial and time decomposition. In the first case, a parallel variant of the conjugated gradient method with multiple local preconditioning is formulated and analyzed. The method is tested for simple applications (e.g. flow around a cylinder). The second part of the publication describes a direct numerical simulation of turbulent flow around a sphere at a Reynolds number of 5000 (based on flow velocity and sphere diameter). Current and Reynolds-averaged flow fields are discussed. Particular emphasis is placed on coordinate-independent representation of the anisotropy ratios of the Reynolds tensor and dissipation tensor. (orig.) [Deutsch] Ein Finite-Volumen-Verfahren fuer die Berechnung stationaerer und instationaerer Stroemungen auf unstrukturierten Netzen wird durch Gebietszerlegung im Raum und Zeit parallelisiert. Fuer die raeumliche Zerlegung wird eine parallele Variante der konjugierten Gradienten Methode mit mehrfacher, lokaler Vorkonditionierung formuliert und analysiert. Anhand einfacher Anwendungsbeispiele (Zylinderumstroemung, deckelgetriebene Nischenstroemung) wird das entwickelte Gesamtverfahren getestet und seine Effizienz bestimmt. Der zweite Teil der Arbeit beschreibt eine direkte numerische Simulation der turbulenten Kugelumstroemung bei einer Reynolds-Zahl von 5 000 (basierend auf Anstroemgeschwindigkeit und Kugeldurchmesser). In der Ergebnisauswertung werden augenblickliche und Reynolds-gemittelte Stroemungsfelder diskutiert und besonderer Wert auf eine koordinatenunabhaengige Darstellung der Anisotropieverhaeltnisse des Reynolds-Tensors und des Dissipationstensors gelegt.

Full Text Available En el presente trabajo se aborda la crítica a la doctrina hegeliana de la mediación (Vermittlung que Kierkegaard desarrolla en el segundo volumen de Enten-Eller (O lo uno o lo otro. El trabajo comienza con un análisis del tipo de oposición que Kierkegaard no está dispuesto a relativizar por vía del recurso a la mediación dialéctica. Para ello se aplican los aportes realizados por Shannon Nason para la comprensión de los opuestos relativos en Hegel y en Kierkegaard. Luego se señala el lugar que le confiere este último filósofo al concepto de mediación en su posición propia, a saber, dentro de la “esfera del pensamiento”. Posteriormente se aborda la crítica de Theodor W. Adorno al intento kierkegaardiano de desarrollar una “dialéctica sin mediación”. En el último apartado se evalúa, en conjunto, la crítica y limitación del concepto de mediación realizadas por Kierkegaard, así como las objeciones elevadas por Adorno contra las mismas. Asimismo, se presentan algunas reflexiones sobre la crítica de la mediación por parte de Kierkegaard y del joven Marx como expresión de una crítica social que permanece implícita en el primero y se muestra explícitamente en el segundo.

The impact of self-archiving on journals and publishers is an important topic for all those involved in scholarly communication. There is some evidence that the physics arXiv has had no impact on physics journals, while 'economic common sense' suggests that some impact is inevitable. I shall review recent studies of librarian attitudes towards repositories and journals, and place this in the context of IOP Publishing's experiences with arXiv. I shall offer some possible reasons for the mis-match between these perspectives and then discuss how IOP has linked with arXiv and experimented with OA publishing. As well as launching OA journals we have co-operated with Cornell and the arXiv on Eprintweb.org, a platform that offers new features to repository users. View Andrew Wray's biography

Bolonia posee unas fuentes documentales notariales, los regisros fiscales de los Memoriali, y otros testimonios igualmente preciosos, que permiten trazar un panorama de la presencia española en la gran Universidad italiana a lo largo del primer tercio del siglo xiv. El objeto de la investigación es la vida, las actividades y la organización interna de la comunidad estudiantil española en Bolonia, y el papel de los jóvenes escolares, principalmente juristas, en la evolución del Estudio y de la ciudad.

Full Text Available El minador de los cítricos, Phyllocnistis citrella, produce daños directos al afectar los brotes nuevos de las plantas jóvenes, e indirectos al permitir la entrada de la bacteria responsable de la cancrosis de los cítricos, a través de las heridas que producen las larvas en las hojas. Este daño indirecto motivó a los productores citrícolas a controlar las poblaciones del minador también en plantas adultas. El objetivo del presente trabajo fue evaluar el control de P. citrella mediante aplicaciones con bajo volumen de abamectin y spinosad, combinados con aceite mineral emulsionable. Las aplicaciones de bajo volumen se hicieron durante tres campañas consecutivas sobre plantas de limonero de siete años de edad al momento de iniciar las experiencias, usando 2 l de caldo formulado por planta. Los tratamientos evaluados fueron: abamectin (1,8 g i.a./ha, spinosad (24 g i.a./ha, ambos combinados con aceite mineral, y un testigo sin tratar. Se hicieron dos aplicaciones por campaña cada 15 días. Se extrajeron muestras semanalmente para evaluar el porcentaje de hojas con larvas vivas. Al final de la experiencia se estimó el daño foliar en brotes previamente marcados. Tanto abamectin como spinosad controlaron la plaga durante 14 días y el porcentaje de área foliar dañada fue menor a 3,5%. El control obtenido con ambos tratamientos, nos permite disponer de dos opciones de activos para el control del minador con el fin de rotar los productos y evitar posibles problemas de resistencia.The citrus leafminer, Phyllocnistis citrella, produces direct damages affecting new flushes of young trees, and indirect ones, since the wounds produced on the leaves by the leafminer represent an entry way for the bacterium responsible for citrus canker.

Full Text Available Se analizó el impacto del clima en los problemas de salinidad, drenaje y producción agrícola en el Distrito de Riego 038 río Mayo Sonora el cual presenta afectaciones por sales en 32% de su superficie. Con datos de clima y agronómicos generados entre 1970-2001, se elaboraron modelos de regresión lineal simple para estudiar la relación entre la superficie ensalitrada con la temperatura ambiente, superficie afectada por niveles freáticos superficiales, volumen de riego, salinidad del agua de riego, precipitación pluvial, producción agrícola y productividad del agua. Asimismo, se correlacionó el manto freático con la temperatura, volumen de riego y precipitación pluvial. La producción se correlacionó con la salinidad del suelo, temperatura ambiente, superficie afectada por niveles freáticos superficiales y volumen de riego. Además, por medio de modelos de regresión lineal múltiple se determinaron las relaciones tanto de la superficie ensalitrada como de la producción agrícola, con la temperatura, superficie afectada por niveles freáticos superficiales, volumen de riego, superficie cosechada y precipitación pluvial. Los resultados evidenciaron que el aumento de superficie ensalitrada está relacionado con el incremento de temperatura; mismo que se asoció con la disminución del volumen de cosechas y con el aumento de superficie con niveles freáticos. Se encontró que los volúmenes de riego impactan en el incremento de la superficie agrícola con niveles freáticos someros y con el aumento de superficie ensalitrada. Con el calentamiento global los problemas de salinidad del suelo se incrementaron entre 24.1 y 15.8% en los estratos de suelo a 30 y 60 cm de profundidad, respectivamente. Asimismo, se estimó un crecimiento del 21.9% de superficies con niveles freáticos superficiales. El impacto del calentamiento global en el volumen de producción agrícola se estimó en una reducción del 18.9% del volumen de cosechas.

The soil vulnerability determines the sensitivity of the soil after accidental radioactive contamination due to Cs-137 and Sr-90. The Departamento de Impacto Ambiental de la Energia of CIEMAT is carrying out an assessment of the radiological vulnerability of the different Spanish soils found on the Iberian Peninsula. This requires the knowledge of the soil properties for the various types of existing soils. In order to achieve this aim, bibliographical compilation of soil profiles has been made to characterize the different soil types and create a database of their properties. Depending on the year of publication and the type of documentary source, the information compiled from the available bibliography is very heterogeneous. Therefore, an important effort has been made to normalize and process the information prior to its incorporation to the database. (Author) 34 refs.

Full Text Available El híbrido intervarietal de chile manzano (Capsicum pubescens R y P Puebla x Zongolica es de alto rendimiento por su volumen, grosor de pericarpio y peso de fruto. El rendimiento se explica principalmente por el tamaño del fruto, siendo recomendable conocer la dinámica del crecimiento del mismo. Normalmente su análisis se realiza por medio de muestreos destructivos, lo que hace imposible utilizar el mismo fruto durante el ciclo de cultivo, además la competencia entre los órganos de la planta disminuye su tamaño y peso, afectando negativamente la calidad y rendimiento. Por lo cual el estudio del crecimiento a través de modelos matemáticos utilizando variables no destructivas permite proponer un manejo adecuado del cultivo. Por esta razón se propuso evaluar e identificar modelos matemáticos que describan el crecimiento del fruto, sin realizar muestreos destructivos. Se evaluaron los modelos: regresión lineal simple, regresión lineal múltiple y cuatro modelos no lineales. Con la hipótesis de que alguno de los seis modelos estudiados, explica eficientemente dicho crecimiento por medio de la variable independiente volumen de agua desplazada. Las plantas de chile se cultivaron bajo un sistema de producción intensivo, en 2004 y 2005. La variable dependiente fue el peso fresco de fruto y las variables independientes fueron: tiempo de crecimiento del fruto, longitud, ancho promedio de los hombros del fruto, volumen de agua desplazada y volumen del mismo. Se encontraron diferencias significativas entre las medias de las variables evaluadas en los dos periodos de muestreo (P<0.05. Los modelos que mejor explican el crecimiento del fruto son: regresión lineal simple (sólo en el 2004 en función del volumen de agua desplazada y el volumen de fruto, el modelo de regresión lineal múltiple describe adecuadamente dicho crecimiento utilizando además de las variables anteriormente mencionadas, el tiempo de crecimiento, la longitud y el ancho

We study the gluon distribution produced via successive medium-induced branchings by an energetic jet propagating through a weakly-coupled quark-gluon plasma. We show that under suitable approximations, the jet evolution is a Markovian stochastic process, which is exactly solvable. For this process, we construct exact analytic solutions for all the n-point correlation functions describing the gluon distribution in the space of energy [M. A. Escobedo, E. Iancu, Event-by-event fluctuations in the medium-induced jet evolution, JHEP 05 (2016) 008. arXiv:arxiv:arXiv:1601.03629, doi:http://dx.doi.org/10.1007/JHEP05(2016)008, M. A. Escobedo, E.

Using these results, we study the event-by-event distribution of the energy lost by the jet at large angles and of the multiplicities of the soft particles which carry this energy. We find that the event-by-event fluctuations are huge: the standard deviation in the energy loss is parametrically as large as its mean value [M. A. Escobedo, E. Iancu, Event-by-event fluctuations in the medium-induced jet evolution, JHEP 05 (2016) 008. arXiv:arxiv:arXiv:1601.03629, doi:http://dx.doi.org/10.1007/JHEP05(2016)008]. This has important consequences for the phenomenology of di-jet asymmetry in Pb+Pb collisions at the LHC: it implies that the fluctuations in the branching process can contribute to the measured asymmetry on an equal footing with the geometry of the di-jet event (i.e. as the difference between the in-medium path lengths of the two jets). We compute the higher moments of the multiplicity distribution and identify a remarkable regularity known as Koba-Nielsen-Olesen (KNO) scaling [M. A. Escobedo, E. Iancu, Multi-particle correlations and KNO scaling in the medium-induced jet evolution, JHEP 12 (2016) 104. arXiv:arxiv:arXiv:1609.06104, doi

THE MYSTERIOUS CASE OF THE SOLAR ARGON ABUNDANCE NEAR SUNSPOTS IN FLARES

International Nuclear Information System (INIS)

Doschek, G. A.; Warren, H. P.

2016-01-01

Recently we discussed an enhancement of the abundance of Ar xiv relative to Ca xiv near a sunspot during a flare, observed in spectra recorded by the Extreme-ultraviolet Imaging Spectrometer (EIS) on the Hinode spacecraft. The observed Ar xiv/Ca xiv ratio yields an argon/calcium abundance ratio seven times greater than expected from the photospheric abundance. Such a large abundance anomaly is unprecedented in the solar atmosphere. We interpreted this result as being due to an inverse first ionization potential (FIP) effect. In the published work, two lines of Ar xiv were observed, and one line was tentatively identified as an Ar xi line. In this paper, we report observing a similar enhancement in a full-CCD EIS flare spectrum in 13 argon lines that lie within the EIS wavelength ranges. The observed lines include two Ar xi lines, four Ar xiii lines, six Ar xiv lines, and one Ar xv line. The enhancement is far less than reported in Doschek et al. but exhibits similar morphology. The argon abundance is close to a photospheric abundance in the enhanced area, and the abundance could be photospheric. This enhancement occurs in association with a sunspot in a small area only a few arcseconds (1″ = about 700 km) in size. There is no enhancement effect observed in the normally high-FIP sulfur and oxygen line ratios relative to lines of low-FIP elements available to EIS. Calculations of path lengths in the strongest enhanced area in Doschek et al. indicate a depletion of low-FIP elements.

Full Text Available La búsqueda de alternativas energéticas de origen renova-ble y la disminución de gases de efecto invernadero pro-venientes de la descomposición de desechos orgánicos hacen del biogás una prometedora alternativa para la sustitución de combustibles fósiles y para la valorización energética de residuos orgánicos en zonas urbanas, rura-les y agroindustriales. En el presente trabajo se realizó un análisis de sensibilidad de las propiedades de combustión del biogás con enriquecimiento de aire con oxígeno en un rango entre 22 y 35% O2. Los resultados indican que la velocidad de deflagración laminar, la temperatura de lla-ma adiabática, el porcentaje en volumen de CO2, la tem-peratura de rocío y el porcentaje de H2O se incrementa-ron cuando el porcentaje de oxígeno en el aire fue mayor que 21% O2, mientras que propiedades como el volumen de aire estequiométrico, volumen de humos húmedos, vo-lumen de humos secos y la energía mínima de ignición, disminuyeron.

Cosmological dynamical systems

CERN Document Server

Leon, Genly

2011-01-01

In this book are studied, from the perspective of the dynamical systems, several Universe models. In chapter 1 we give a bird's eye view on cosmology and cosmological problems. Chapter 2 is devoted to a brief review on some results and useful tools from the qualitative theory of dynamical systems. They provide the theoretical basis for the qualitative study of concrete cosmological models. Chapters 1 and 2 are a review of well-known results. Chapters 3, 4, 5 and 6 are devoted to our main results. In these chapters are extended and settled in a substantially different, more strict mathematical language, several results obtained by one of us in arXiv:0812.1013 [gr-qc]; arXiv:1009.0689 [gr-qc]; arXiv:0904.1577[gr-qc]; and arXiv:0909.3571 [hep-th]. In chapter 6, we provide a different approach to the subject discussed in astro-ph/0503478. Additionally, we perform a Poincar\\'e compactification process allowing to construct a global phase space containing all the cosmological information in both finite and infinite...

Multiple determinants controlling activation of yeast replication origins late in S phase.

Science.gov (United States)

Friedman, K L; Diller, J D; Ferguson, B M; Nyland, S V; Brewer, B J; Fangman, W L

1996-07-01

Analysis of a 131-kb segment of the left arm of yeast chromosome XIV beginning 157 kb from the telomere reveals four highly active origins of replication that initiate replication late in S phase. Previous work has shown that telomeres act as determinants for late origin activation. However, at least two of the chromosome XIV origins maintain their late activation time when located on large circular plasmids, indicating that late replication is independent of telomeres. Analysis of the replication time of plasmid derivatives containing varying amounts of chromosome XIV DNA show that a minimum of three chromosomal elements, distinct from each tested origin, contribute to late activation time. These late determinants are functionally equivalent, because duplication of one set of contributing sequences can compensate for the removal of another set. Furthermore, insertion of an origin that is normally early activated into this domain results in a shift to late activation, suggesting that the chromosome XIV origins are not unique in their ability to respond to the late determinants.

Full Text Available Con el objetivo de evaluar la tipología de productores en la región socio-económica XIV Tulijá-Tseltal-Chol en el estado de Chiapas, México se hizo un estudio con carácter regional de los sistemas productivos. Se u tilizaron entrevistas directas con productores (317 de las unidades de producción agropecuaria, haciendo recorridos por l os municipios de esta región que se caracterizan por estar formadas de etnias de origen mayense (Tseltales, Choles y Tsotsiles, con una fuerte presencia de mestizos y de descendientes de europeos. Se exploraron 48 variables que fueron preseleccionadas quedando 11 par a su análisis por medio del análisis multivariado. Los resultados muestran que se pueden diferenciar cuatro tipos de productores que comparten actividades productivas, como dar sa les minerales y participar en campañas zoosanitarias, pero, diferentes en otros aspectos como el nivel educativo. Otro aspecto compartido es el bajo nivel de desarrollo tecnológico que parece demostrar la escasa promoción de su uso que podría mejorar la capacidad productiva y que en apa riencia parece estar limitado por la cantidad de terreno. Se concluye que la tipología descrita es factible de utilizarse como clasificación para comprender e im pulsar que los recursos que se destinen para apuntalar la producción regional deben contener políticas diferenciada s, y a su vez generar tecnología moderna apropiada, de real aplicación a las condiciones geo-ecológicas de la regi ón, así como la promoción del uso de la misma que reconozca la biodiversidad y la producción sustentable como parte de las estrategias de desarrollo.

Localization of vector field on dynamical domain wall

Directory of Open Access Journals (Sweden)

Masafumi Higuchi

2017-03-01

Full Text Available In the previous works (arXiv:1202.5375 and arXiv:1402.1346, the dynamical domain wall, where the four dimensional FRW universe is embedded in the five dimensional space–time, has been realized by using two scalar fields. In this paper, we consider the localization of vector field in three formulations. The first formulation was investigated in the previous paper (arXiv:1510.01099 for the U(1 gauge field. In the second formulation, we investigate the Dvali–Shifman mechanism (arXiv:hep-th/9612128, where the non-abelian gauge field is confined in the bulk but the gauge symmetry is spontaneously broken on the domain wall. In the third formulation, we investigate the Kaluza–Klein modes coming from the five dimensional graviton. In the Randall–Sundrum model, the graviton was localized on the brane. We show that the (5,μ components (μ=0,1,2,3 of the graviton are also localized on the domain wall and can be regarded as the vector field on the domain wall. There are, however, some corrections coming from the bulk extra dimension if the domain wall universe is expanding.

Full Text Available The present article represents an approximation to the food of some German miners settled in Pamplona at the end of the 14th century, to carry out a series of assays intended to determine the kind of metals present in the ore and their actual proportion, with the purpose to verify the profitability of some seams found at Five Villages. Their food accounting for approximately one and a half months, give us first hand information of their habits and of those sharing the table with them. To a certain extent, it is possible to extrapolate these practices to the ones of part of Navarra's salary earners. In them, we could sense certain customs or preferences characteristic of North Europe.

Las cuentas de los gastos que realizan en alimentación, en aprox. mes y medio, nos acercan de primera mano a los hábitos de estos hombres y de quienes les acompañan en la mesa. Unas prácticas que es posible extrapolar, en cierta medida, a parte de la menestralía navarra, y en las que podemos intuir ciertas costumbres (o gustos propios de la Europa del Norte.

Meson spectroscopy at finite gauge coupling - whereat any perturbative QCD computation would break down - and finite number of colors, from a top-down holographic string model, has thus far been entirely missing in the literature.

The black-hole gravity dual (with a horizon radius smaller than the deconfinement scale) also provides the expected large- N suppressed decrease in vector meson mass with increase of temperature.

Meson spectroscopy at finite gauge coupling - whereat any perturbative QCD computation would break down - and finite number of colors, from a top-down holographic string model, has thus far been entirely missing in the literature. This paper fills this gap. Using the delocalized type IIA SYZ mirror (with SU(3) structure) of the holographic type IIB dual of large-N thermal QCD of Mia et al.

The soil vulnerability determines the sensitivity of the soil after an accidental radioactive contamination due to Cs-137 and Sr-90. The Department de Impacto Ambiental de la Energia of CIEMAT is carrying out an assessment of the radiological vulnerability of the different Spanish soils found on the Iberian Peninsula. This requires the knowledge of the soil properties for the various types of existing soils. In order to achieve this aim, a bibliographical compilation of soil profiles has been made to characterize the different soil types and create a database of their properties. Depending on the year of publication and the type of documentary source, the information compiled from the available bibliography is very heterogeneous. Therefore, an important effort has been made to normalize and process the information prior to its incorporation to the database.

We review the current status of the leptogenesis scenario originally proposed by Akhmedov, Rubakov and Smirnov (ARS). It takes place in the parametric regime where the right-handed neutrinos are at the electroweak scale or below and the CP-violating effects are induced by the coherent superposition of different right-handed mass eigenstates. Two main theoretical approaches to derive quantum kinetic equations, the Hamiltonian time evolution as well as the Closed-Time-Path technique are presented, and we discuss their relations. For scenarios with two right-handed neutrinos, we chart the viable parameter space. Both, a Bayesian analysis, that determines the most likely configurations for viable leptogenesis given different variants of flat priors, and a determination of the maximally allowed mixing between the light, mostly left-handed, and heavy, mostly right-handed, neutrino states are discussed. Rephasing invariants are shown to be a useful tool to classify and to understand various distinct contributions to...

The LHC has been in luminosity production mode for the last couple of weeks. Peak luminosities have ranged between 6 and a record 7.74 x 1033 cm -2 s-1. Integrated luminosities per fill have been healthy, with 170 inverse picobarn per fill reached on five occasions in the last two weeks.  The total integrated luminosity for the year has passed 14 inverse femtobarns.   Injected bunch currents have peaked at an average of  1.69 x 1011 protons per bunch on average - a remarkable achievement for both the injectors and the LHC: the injectors to be able to produce good quality beam at these intensities; the LHC for being able to cope with these intensities without excessive losses. Peak performance from day to day depends strongly on the beam sizes and bunch intensities delivered by the injectors. It is a continual challenge to keep the Booster, PS and SPS optimally tuned while they deliver beams to their other wide range of users. Despite the excel...

The focus of this chapter lies on the possible experimental tests of leptogenesis scenarios. We consider both leptogenesis generated from oscillations, as well as leptogenesis from out-of-equilibrium decays. As the Akhmedov-Rubakov-Smirnov (ARS) mechanism allows for heavy neutrinos in the GeV range, this opens up a plethora of possible experimental tests, e.g. at neutrino oscillation experiments, neutrinoless double beta decay, and direct searches for neutral heavy leptons at future facilities. In contrast, testing leptogenesis from out-of-equilibrium decays is a quite difficult task. We comment on the necessary conditions for having successful leptogenesis at the TeV-scale. We further discuss possible realizations and their model specific testability in extended seesaw models, models with extended gauge sectors, and supersymmetric leptogenesis. Not being able to test high-scale leptogenesis directly, we present a way to falsify such scenarios by focusing on their washout processes. This is discussed specific...

L’athéisme au prisme des psaumes : étude comparée de quatre sermons réformés sur le psaume XIV au XVIIe siècle Atheism in the prism of psalms : comparative study on Psalm XIV in the 17th century

Full Text Available L’article propose une étude comparée de quatre sermons protestants sur l’athéisme prenant appui sur ce verset du psaume XIV, « L’insensé a dit en son cœur : il n’y a point de Dieu ». Bien qu’appartenant à des générations différentes, les auteurs de ces sermons, Amyraut, Gaches, Morus et Superville, font le choix d’un traitement similaire du thème de l’athéisme ; de fait, le verset d’appui du sermon, qui n’a rien d’original en la matière, montre bien que nous sommes devant un sujet d’école avec ses passages obligés, et sans prise réelle sur l’actualité politique et théologique du siècle. Il n’est donc pas étonnant de retrouver globalement les mêmes types d’arguments dans chacun de ces sermons. En revanche, au-delà des particularités d’écriture propres à chacun des auteurs, on mesure l’incroyable modernité de la prédication d’Amyraut, sa richesse et sa densité, à travers deux éléments de démonstration dont la postérité fera si grand cas après Pascal et Voltaire : l’idée d’un pari sur l’existence de Dieu et la conception du Dieu-horloger.This article presents a comparative study of four sermons against atheism written by seventeenth-century Protestant ministers on Psalm 14.1: “The fool hath said in his heart, There is no God”. Though belonging to different generations, the authors, Amyraut, Gaches, Morus and Superville, deal with the refutation of atheism in the same way: the choice of Psalm 14.1 to preach against atheism is by no means original, the arguments proving the existence of God are repeated from one text to another and the sermons do not broach any of the century’s political and theological issues. It is noteworthy, however, that Amyraut’s sermon introduces two arguments which were to have an important posterity after Pascal and Voltaire: the idea that one should wager that God exists and the conception of God as a clockmaker.

Full Text Available El estudio de la morfometría ovárica está directamente relacionado con sus aplicaciones para analizar e interpretar los hallazgos, en los exámenes ginecológicos de las vacas. Para este trabajo se recolectaron 114 pares de ovarios en frigorífico, clasificados a partir del ancho, grueso, largo, volumen, diámetro del folículo, diámetro y área del cuerpo lúteo. Fue observada una diferencia significativa en el ancho (1,95cm y 1,83cm y el volumen (7,26 mL y 6,23 mL de los ovarios izquierdos y derechos, respectivamente. En cuanto al tamaño y el volumen de los folículos, el diámetro y el área de los cuerpos lúteos, no hubo diferencia relevante. En los lados hubo correlación positiva (p<0,01 entre el volumen del ovario izquierdo y el área del cuerpo lúteo. La presencia de folículos con diámetro igual o superior a 9mm, el cuerpo lúteo de tipo macizo y protruso presente en 43,39% de los 53 ovarios, predominó con relación al tipo cóncavo. De los 84 ovarios con cuerpos lúteos, el 26,20% eran de tipo extrapolado. Se concluye, que la presencia de cuerpo lúteo incluso, en vacas cebú, puede resultar en fallas diagnósticas durante el examen de palpación rectal para estimar la actividad ovárica.

A Solution Space for a System of Null-State Partial Differential Equations: Part 3

Science.gov (United States)

Flores, Steven M.; Kleban, Peter

2015-01-01

This article is the third of four that completely and rigorously characterize a solution space for a homogeneous system of 2 N + 3 linear partial differential equations (PDEs) in 2 N variables that arises in conformal field theory (CFT) and multiple Schramm-Löwner evolution (SLE κ ). The system comprises 2 N null-state equations and three conformal Ward identities that govern CFT correlation functions of 2 N one-leg boundary operators. In the first two articles (Flores and Kleban, in Commun Math Phys, arXiv:1212.2301, 2012; Commun Math Phys, arXiv:1404.0035, 2014), we use methods of analysis and linear algebra to prove that dim , with C N the Nth Catalan number. Extending these results, we prove in this article that dim and entirely consists of (real-valued) solutions constructed with the CFT Coulomb gas (contour integral) formalism. In order to prove this claim, we show that a certain set of C N such solutions is linearly independent. Because the formulas for these solutions are complicated, we prove linear independence indirectly. We use the linear injective map of Lemma 15 in Flores and Kleban (Commun Math Phys, arXiv:1212.2301, 2012) to send each solution of the mentioned set to a vector in , whose components we find as inner products of elements in a Temperley-Lieb algebra. We gather these vectors together as columns of a symmetric matrix, with the form of a meander matrix. If the determinant of this matrix does not vanish, then the set of C N Coulomb gas solutions is linearly independent. And if this determinant does vanish, then we construct an alternative set of C N Coulomb gas solutions and follow a similar procedure to show that this set is linearly independent. The latter situation is closely related to CFT minimal models. We emphasize that, although the system of PDEs arises in CFT in away that is typically non-rigorous, our treatment of this system here and in Flores and Kleban (Commun Math Phys, arXiv:1212.2301, 2012; Commun Math Phys, arXiv:1404

Meson spectroscopy at finite gauge coupling - whereat any perturbative QCD computation would break down - and finite number of colors, from a top-down holographic string model, has thus far been entirely missing in the literature. This paper fills this gap. Using the delocalized type IIA SYZ mirror (with SU(3) structure) of the holographic type IIB dual of large-N thermal QCD of Mia et al. (Nucl Phys B 839:187. arXiv:0902.1540 [hep-th], 2010) as constructed in Dhuria and Misra (JHEP 1311:001. arXiv:1306.4339 [hep-th], 2013) at finite coupling and number of colors (N{sub c} = number of D5(D5)-branes wrapping a vanishing two-cycle in the top-down holographic construct of Mia et al. (Nucl Phys B 839:187. arXiv:0902.1540 [hep-th], 2010) = O(1) in the IR in the MQGP limit of Dhuria and Misra (JHEP 1311:001. arXiv:1306.4339 [hep-th], 2013) at the end of a Seiberg-duality cascade), we obtain analytical (not just numerical) expressions for the vector and scalar meson spectra and compare our results with previous calculations of Sakai and Sugimoto (Prog Theor Phys 113:843. doi:10.1143/PTP.113.843 arXiv:hep-th/0412141, 2005) and Dasgupta et al. (JHEP 1507:122. doi:10.1007/JHEP07(2015)122 arXiv:1409.0559 [hep-th], 2015), and we obtain a closer match with the Particle Data Group (PDG) results of Olive et al. (Particle Data Group) (Chin Phys C 38:090001, 2014). Through explicit computations, we verify that the vector and scalar meson spectra obtained by the gravity dual with a black hole for all temperatures (small and large) are nearly isospectral with the spectra obtained by a thermal gravity dual valid for only low temperatures; the isospectrality is much closer for vector mesons than scalar mesons. The black-hole gravity dual (with a horizon radius smaller than the deconfinement scale) also provides the expected large-N suppressed decrease in vector meson mass with increase of temperature.

We present off-shell N=2 supergravity actions, which exhibit spontaneously broken local supersymmetry and allow for de Sitter vacua for certain values of the parameters. They are obtained by coupling the standard N=2 supergravity-matter systems to the Goldstino superfields introduced in arXiv:1105.3001 and arXiv:1607.01277 in the rigid supersymmetric case. These N=2 Goldstino superfields include nilpotent chiral and linear supermultiplets. We also describe a new reducible N=1 Goldstino supermultiplet.

IEA joint action. Aerodynamics of wind turbines

Energy Technology Data Exchange (ETDEWEB)

Maribo Pedersen, B. [ed.

1997-12-31

In the period 1992-1997 the IEA Annex XIV `Field Rotor Aerodynamics` was carried out. Within its framework 5 institutes from 4 different countries participated in performing detailed aerodynamic measurements on full-scale wind turbines. The Annex was successfully completed and resulted in a unique database of aerodynamic measurements. The database is stored on an ECN disc (available through ftp) and on a CD-ROM. It is expected that this base will be used extensively in the development and validation of new aerodynamic models. Nevertheless at the end of IEA Annex XIV, it was recommended to perform a new IEA Annex due to the following reasons: In Annex XIV several data exchange rounds appeared to be necessary before a satisfactory result was achieved. This is due to the huge amount of data which had to be supplied, by which a thorough inspection of all data is very difficult and very time consuming; Most experimental facilities are still operational and new, very useful, measurements are expected in the near future; The definition of angle of attack and dynamic pressure in the rotating environment is less straightforward than in the wind tunnel. The conclusion from Annex XIV was that the uncertainty which results from these different definitions is still too large and more investigation in this field is required. (EG)

Metodología: el protocolo experimental se realizó en banda rodante, luego de nueve minutos de calentamiento, a una velocidad equivalente al 50% de la FCR y con una pendiente del 1%; siguieron 88 minutos de carrera, en tres intervalos, los dos iniciales de 29 minutos y el último de 30; la pendiente se mantuvo y la velocidad se incrementó al 80% de la FCR; finalmente, 90 minutos de recuperación, en tres intervalos de 30 minutos cada uno. No se hizo reposición hídrica durante el tratamiento deshidratado (DH; durante los tratamientos con hidratación se empleó un volumen similar de tres bebidas de diferente osmolaridad (H-I, H-II, H-III, el cual fue ingerido ad libitum. Resultados: durante la etapa de ejercicio la pérdida hídrica fue de 1.440 ml/h mientras que el volumen ingerido fue de 407 ml/h. Se observó, en cada uno de los tratamientos, una pérdida porcentual del PC (p<0,001; un incremento de la FC (p<0,05, y excepto con H-II y H-III una reducción porcentual del VP (p<0,05. No hubo diferencias intertratamientos en el porcentaje de la pérdida del PC, en el aumento de la FC ni en la reducción porcentual del VP. Conclusiones: la ingesta ad libitum fue menor que la cantidad recomendada internacionalmente por lo que, probablemente, no se pudieron establecer los efectos de la osmolaridad de las bebidas hidratantes sobre las variables estudiadas.

Comment on "The third Zemach moment of the proton", by Cloet and Miller

De Rújula, A

2010-01-01

Cloet and Miller, in arXiv:1008.4345, state that "existing data rule out a value of the third Zemach moment large enough to explain the current puzzle with the proton charge radius determined from the Lamb shift in muonic Hydrogen. This is in contrast with the recent claim of De R\\'ujula [arXiv:1008.3861]". To be more precise: it is not. It is, however, contrary to what they claim that I claim. Cloet and Miller have simply misinterpreted my claims.

To describe the physiological pattern of gestational plasma volume adjustments in normal singleton pregnancy and compare this with the pattern in pregnancies complicated by pregnancy-induced hypertension, pre-eclampsia or fetal growth restriction. We performed a meta-analysis of the current literature on plasma volume adjustments during physiological and complicated pregnancies. Literature was retrieved from PubMed (NCBI) and EMBASE (Ovid) databases. Included studies reported both reference plasma volume measurements (non-pregnant, prepregnancy or postpartum) and measurements obtained during predetermined gestational ages. Mean differences bet ween the reference and pregnancy plasma volume measurements were calculated for predefined intervals of gestational age using a random-effects model described by DerSimonian and Laird. Thirty studies were included in the meta-analysis with publication dates ranging from 1934 to 2007. Plasma volume increased in the first weeks of pregnancy, with the steepest increase occurring during the second trimester. Plasma volume continued to increase in the third trimester with a pooled maximum increase of 1.13 L (95% CI, 1.07-1.19 L), an increase of 45.6% (95% CI, 43.0-48.1%) in physiological pregnancies compared with the reference value. The plasma volume expansion in gestational hypertensive and growth-restricted pregnancies was 0.80 L (95% CI, 0.59-1.02 L), an increase of 32.3% (95% CI, 23.6-41.1%) in the third trimester, a smaller increase than in physiological pregnancies (P embarazo: una revisi\\xF3n sistemática y metaanálisis RESUMEN OBJETIVO: Describir el patrón fisiológico de los cambios en el volumen del plasma gestacional en embarazos normales con feto único y compararlo con el patrón en los embarazos complicados por hipertensión gestacional, preeclampsia o restricción del crecimiento fetal.

Exploring overlay journals: the RIOJA project

CERN Multimedia

CERN. Geneva

2007-01-01

Researchers in cosmology and astrophysics depend on the arXiv repository for the registration and dissemination of their work, as well as for current awareness, yet they continue to submit papers to journals for review. Could rapid quality certification be overlaid directly onto the arXiv repository? This presentation introduces the RIOJA (Repository Interface to Overlaid Journal Archives) project, on which a group of cosmology researchers from the UK is working with UCL Library Services and Cornell University. The project is creating a tool to support the overlay of journals onto repositories, and will demonstrate a cosmology journal overlaid on top of arXiv. RIOJA will also work with the cosmology community to explore the social and economic aspects of journal overlay in this discipline: what other value, besides the quality stamp, does journal publication typically add? What are the costs of the ideal overlay journal for this community, and how could those costs be recovered? Would researchers real...

Open archives, the expectations of the scientific communities

2007-01-01

Open archives (OA) started in physics more than 15 years ago with ArXiv, and have since played a more and more important role in the activity of the disciplin; actually, in many fields of physics, ArXiv has now become the major vector or scientific communication. We now have two communication channels in parallel, traditional scientific journals with peer review, and open archives, both with different functionalities and both indispensable. It it therefore interesting to try and transpose to other disciplins the scheme that has worked so well for physicists, which means that the reasons for the success of ArXiv should be analyzed. Scientists do not care about the technicalities, and whether or not the OA is centralized, or distributed with a high level of interoperability. What they wish is to have one single interface where all the scientific information in their domain is available, with the same scientific classifications, etc.. In case of collaborations beween different institutions, they do not wish to ...

De las propiedades medidas se calculó, el volumen molar de exceso, la desviación de la velocidad del sonido, la desviación de la viscosidad y el exceso de energía de activación por flujo viscoso. El volumen molar de exceso y la desviación de la velocidad del sonido presentaron valores positivos, mientras que la desviación de la viscosidad resultó negativa. Se aplicaron ecuaciones empíricas a las propiedades derivadas para determinar sus parámetros de ajuste, obteniéndose buenos resultados. Se realizó la predicción de la velocidad del sonido con modelos disponibles en la literatura y la predicción de la viscosidad con modelos de contribución de grupos; en ambos casos los resultados obtenidos fueron aceptables.

We explore a local form of second-order Vasiliev equations proposed in [arxiv:arXiv:1706.03718] and obtain an explicit expression for quadratic corrections to bosonic Fronsdal equations, generated by gauge-invariant higher-spin currents. Our analysis is performed for general phase factor, and for the case of parity-invariant theory we find the agreement with expressions for cubic vertices available in the literature. This provides an additional indication that local frame proposed in [arxiv:arXiv:1706.03718] is the proper one.

The soil vulnerability determines the sensitivity of the soil after an accidental radioactive contamination due to Cs-137 and Sr-90. The Departamento de Impacto Ambiental de la Energia of CIEMAT is carrying out an assessment of the radiological vulnerability of the different Spanish soils found on the Iberian Peninsula. This requires the knowledge of the soil properties for the various types of existing soils. In order to achieve thin aim, a bibliographical compilation of soil profiles has been made to characterize the different soil types and create a database of their properties. Depending on the year of publication and the type of documentary source, the information compiled from the available bibliography is very heterogeneous. Therefore, an important effort has been made to normalize and process the information prior ot its incorporation to the database. This volume presents the criteria applied to normalize and process the data as well as the soil properties of the various soil types belonging to the provinces of Toledo and Ciudad Real of the Comunidad Autonoma de Castilla-La Mancha.

In the absence of gauge fields, quantum field theories on the Groenewold-Moyal (GM) plane are invariant under a twisted action of the Poincare group if they are formulated following [M. Chaichian, P.P. Kulish, K. Nishijima, A. Tureanu, Phys. Lett. B 604 (2004) 98, (hep-th/0408069); P. Aschieri, C. Blohmann, M. Dimitrijevic, F. Meyer, P. Schupp, J. Wess, Class.

In that formulation, such theories also have no UV-IR mixing [A.P. Balachandran, A. Pinzul, B.A. Qureshi, Phys. Lett. B 634 (2006) 434, (hep-th/0508151)]. Here we investigate UV-IR mixing in gauge theories with matter following the approach of [A.P. Balachandran, A. Pinzul, B. A. Qureshi, S. Vaidya, (hep-th/0608138); A.P. Balachandran, A. Pinzul, B.A. Qureshi, S. Vaidya, (arXiv: 0708.0069 [hep-th])]. We prove that there is UV-IR mixing in the one-loop diagram of the S-matrix involving a coupling between gauge and matter fields on the GM plane, the gauge field being non-Abelian. There is no UV-IR mixing if it is Abelian.

Full Text Available Although seed weight is a key factor in understanding the reproductive biology of plant species, its value is unknown for a large proportion of the herbaceous species in the Mediterranean basin. This paper presents data on seed weight, dimensions and volume for 1 18 herbaceous species in acidic Mediterranean scrub and grassland in the centre of the Iberian Peninsula. This information is used to design predictive models of seed weight using multiple regression models. taking into account the phylogenetic effect. Five groups of models were designed: one using Trifolium species. three. using the families represented by the largest number of species (Catyophyllaceae, Asteraceae and Poaceae; and finally a general model using one species from each of the families present in the sample. The models are rated according to the absorbed variante, their significance in relation to the previous in complexity and the effort required to obtain the data for each one. We also test the validity of seed dimension data taken from literature sources to predict seed weight. The 1-0 seed dimensions are excellent weight predictors in the case of Trifolium (Weight = - 24.55 + 0.10D1 + 3.38D2, r2 = 0.94 and Asteraceae (Weight = - 20.90 + 1.19D1 + 1.67D2, r2 = 0.91 and are quite satisfactory in the case of the general model (Weight = - 16.01 +0.56D1 + 1.6002, r2 = 0.69.El peso de las semillas es un carácter clave para entender la biología reproductiva de las especies vegetales, pero se desconoce su valor para gran parte de las especies herbáceas de la cuenca mediterránea.

New insights into properties of large-N holographic thermal QCD at finite gauge coupling at (the non-conformal/next-to) leading order in N

2016-01-01

It is believed that large-N thermal QCD laboratories like strongly coupled QGP (sQGP) require not only a large 't Hooft coupling but also a finite gauge coupling (Natsuume, String theory and quark-gluon plasma. arXiv:hep-ph/0701201, 2007). Unlike almost all top-down holographic models in the literature, holographic large-N thermal QCD models, based on this assumption, therefore necessarily require addressing this limit from M-theory. This was initiated in Dhuria and Misra (JHEP 1311:001, 2013) which presented a local M-theory uplift of the string theoretic dual of large-N thermal QCD-like theories at finite gauge/string coupling of Mia et al. (Nucl. Phys. B 839:187, arXiv:0902.1540 [hep-th], 2010) (g s Xiv:1306.4339 [hep-th], 2013). Understanding and classifying the properties of systems like sQGP from a top-down holographic model, assuming a finite gauge coupling, have been entirely missing in the literature. In this paper we largely address the following two non-trivial issues pertaining to the same. First, up to LO in N (the number of D3-branes), by calculating the temperature dependence of the thermal (and electrical) conductivity and the consequent deviation from the Wiedemann-Franz law, upon comparison with Garg et al. (Phys. Rev. Lett. 103:096402, 2009), we show that, remarkably, the results qualitatively mimic a 1+1-dimensional Luttinger liquid with impurities. Second, by looking at, respectively, the scalar, vector, and tensor modes of metric perturbations and using the prescription of Kovtun and Starinets (Phys. Rev. D 72:086009, arXiv:hep-th/0506184, 2005) for constructing appropriate gauge-invariant perturbations, we obtain the non-conformal corrections to the conformal results (but at finite g s ), respectively, for the speed of sound, the shear mode diffusion constant, and the shear viscosity η (and (η)/(s)).

We explore the possibility that Dark Matter is the lightest hadron made of two stable color octet Dirac fermions ${\\cal Q}$. The cosmological DM abundance is reproduced for $M_{\\cal Q}\\approx 12.5$ TeV, compatibly with direct searches (the Rayleigh cross section, suppressed by $1/M_{\\cal Q}^6$, is close to present bounds), indirect searches (enhanced by ${\\cal Q}{\\cal Q}+\\bar{\\cal Q}\\bar{\\cal Q}\\to {\\cal Q}\\bar{\\cal Q}+{\\cal Q}\\bar{\\cal Q}$ recombination), and with collider searches (where ${\\cal Q}$ manifests as tracks, pair produced via QCD). Hybrid hadrons, made of $\\cal Q$ and of SM quarks and gluons, have large QCD cross sections, and do not reach underground detectors. Their cosmological abundance is $10^5$ times smaller than DM, such that their unusual signals seem compatible with bounds. Those in the Earth and stars sank to their centers; the Earth crust and meteorites later accumulate a secondary abundance, although their present abundance depends on nuclear and geological properties that we cannot c...

arXiv Medical Physics Commissioning

CERN Document Server

Meer, David

The medical commissioning is an important step to bring a particle gantry into clinical operation for tumour treatments. This involves the parametrization and characterization of all relevant systems including the beam delivery, the patient table, the imaging systems and the connection to all required software components. This article is limited to necessary tasks for the beam delivery system of a pencil beam scanning system. Usually the commissioning starts with the characterization of the unscanned beam and the calibration of the beam energy. The following steps are the parametrization of the scanning system, the commissioning of the beam position monitoring system and characterization of the spot size, all requiring precisions better than 1 mm. The commissioning effort for these tasks depends also on the gantry topology. Finally, the calibration of the dose measurement system ensures that any dose distribution can be delivered with an absolute precision better than 1%.

The Astrophobic Axion arXiv

CERN Document Server

Di Luzio, Luca; Nardi, Enrico; Panci, Paolo; Ziegler, Robert

We propose a class of axion models with generation dependent Peccei-Quinn charges for the known fermions that allow to suppress the axion couplings to nucleons and electrons. Astrophysical limits are thus relaxed, allowing for axion masses up to ${\\cal O}(0.1)$ eV. The axion-photon coupling remains instead sizeable, so that next generation helioscopes will be able to probe this scenario. Astrophobia unavoidably implies flavor violating axion couplings, so that experimental limits on flavour-violating processes can provide complementary probes. The astrophobic axion can be a viable dark matter candidate in the heavy mass window, and can also account for anomalous energy loss in stars.

We introduce the Hyperbolic Higgs, a novel solution to the little hierarchy problem that features Standard Model neutral scalar top partners. At one-loop order, the protection from ultraviolet sensitivity is due to an accidental non-compact symmetry of the Higgs potential that emerges in the infrared. Once the general features of the effective description are detailed, a completion that relies on a five dimensional supersymmetric framework is provided. Novel phenomenology is compared and contrasted with the Twin Higgs scenario.

Recessive mutations in TMEM38B cause type XIV osteogenesis imperfecta (OI) by dysregulating intracellular calcium flux. Clinical and bone material phenotype description and osteoblast differentiation studies. Natural history study in pediatric research centers. Eight patients with type XIV OI. Clinical examinations included bone mineral density, radiographs, echocardiography, and muscle biopsy. Bone biopsy samples (n = 3) were analyzed using histomorphometry, quantitative backscattered electron microscopy, and Raman microspectroscopy. Cellular differentiation studies were performed on proband and control osteoblasts and normal murine osteoclasts. Type XIV OI clinical phenotype ranges from asymptomatic to severe. Previously unreported features include vertebral fractures, periosteal cloaking, coxa vara, and extraskeletal features (muscular hypotonia, cardiac abnormalities). Proband lumbar spine bone density z score was reduced [median -3.3 (range -4.77 to +0.1; n = 7)] and increased by +1.7 (1.17 to 3.0; n = 3) following bisphosphonate therapy. TMEM38B mutant bone has reduced trabecular bone volume, osteoblast, and particularly osteoclast numbers, with >80% reduction in bone resorption. Bone matrix mineralization is normal and nanoporosity low. We demonstrate a complex osteoblast differentiation defect with decreased expression of early markers and increased expression of late and mineralization-related markers. Predominance of trimeric intracellular cation channel type B over type A expression in murine osteoclasts supports an intrinsic osteoclast defect underlying low bone turnover. OI type XIV has a bone histology, matrix mineralization, and osteoblast differentiation pattern that is distinct from OI with collagen defects. Probands are responsive to bisphosphonates and some show muscular and cardiovascular features possibly related to intracellular calcium flux abnormalities. Copyright © 2017 Endocrine Society

In this short note we explain the main idea of the work done in [I. Bena, N. Bobev, C. Ruef and N. P. Warner, (arXiv:0804.4487 [hep-th]); I. Bena, N. Bobev, C. Ruef and N. P. Warner, (arXiv:0812.2942 [hep-th])]. We present a family of black hole microstates, the bubbling solutions. We then explain how supertubes placed in such backgrounds have their entropy enhanced by the presence of the background dipole charges. This indicates this could account for a large amount in the entropy of the three charge black hole.

In arXiv:1707.06803 we derived the subleading multiple soft graviton theorem in a generic quantum theory of gravity for arbitrary number of soft external gravitons and arbitrary number of finite energy external states carrying arbitrary mass and spin. In this paper we verify this explicitly using the CHY formula for tree level scattering amplitudes of arbitrary number of gravitons in Einstein gravity. We pay special care to fix the signs of the amplitudes and resolve an apparent discrepancy between our general results in arXiv:1707.06803 and previous results on soft graviton theorem from CHY formula.

Proposal for novel curcumin derivatives as potent inhibitors against Alzheimer's disease: Ab initio molecular simulations on the specific interactions between amyloid-beta peptide and curcumin

Accumulation of amyloid-β (Aβ) peptides in a brain is closely related with the pathogenesis of Alzheimer's disease. To suppress the production of Aβ peptides, we propose novel curcumin derivatives and investigate their binding properties with the amyloid precursor protein (APP), using protein-ligand docking as well as ab initio molecular simulations. Our proposed derivative (curcumin XIV) is found to have a large binding energy with APP and interacts strongly with the cleavage site Ala19 by secretase. It is thus expected that curcumin XIV can protect APP from the secretase attack and be a potent inhibitor against the production of Aβ peptides.

Um die Interobservervariabilitaet der GTV-Abgrenzung zu bestimmen, wurden das Verhaeltnis des tatsaechlich abgegrenzten Volumens zum geschaetzten Konsensvolumen (STAPLE), das Verhaeltnis des gemeinsamen Volumens zum umfassenden Volumen sowie der Variationskoeffizient berechnet. Das mediane Kappa-Agreement-Level betrug 0,71 (Spanne 0,28-0,86). Das Verhaeltnis des tatsaechlich abgegrenzten Volumens zum geschaetzten Konsensvolumen lag in saemtlichen Faellen zwischen 0,19 und 1,93 (Mittelwert 0,94). Das Verhaeltnis des gemeinsamen Volumens zum umfassenden Volumen lag zwischen 0,001 und 0,56 (Mittelwert 0,25). Der Variationskoeffizient fuer die GTV-Abgrenzung lag im Bereich von 8-57 % (Mittelwert 26 %). Die Interobservervariabilitaet in der Zielabgrenzung des HCC-GTV ist in dieser Studie bemerkenswert.

[Louis XIV's Ginseng: Shaping of Knowledge on an Herbal Medicine in the Late 17th and the Early 18th Century France].

Science.gov (United States)

Lee, Hye-Min

2016-04-01

This article aims to investigate the shaping of knowledge and discourse on ginseng, especially among physicians and botanists, since its introduction to France from the 17th century until the early 18th century. In France, knowledge on herbal medicine, including that of ginseng, was shaped under the influence of the modern state's policy and institution: mercantilism and the Académie royale des sciences. The knowledge of herbal medicine developed as an important part of the mercantilist policy supported systematically by the Académie. The East Asian ginseng, renowned as a panacea, was first introduced into France in the 17th century, initially in a roundabout way through transportation and English and Dutch publications of travel tales from various foreign countries. The publication activity was mainly conducted by Thévenot company with the intention to meet the needs of French mercantilism promoted by Colbert. It also implied interests on medicine in order to bolster the people's health. The Thévenot company's activity thus offered vital information on plants and herbs abroad, one of which was ginseng. Furthermore, with Louis XIV's dispatching of the Jesuit missionaries to East Asia, the Frenchmen were able to directly gather information on ginseng. These information became a basis for research of the Académie. In the Académie, founded in 1666 by Colbert, the king's physicians and botanists systematically and collectively studied on exotic plants and medical herbs including ginseng. They were also key figures of the Jardin du Roi. These institutions bore a striking contrast to the faculty of medicine at the University of Paris which has been a center of the traditional Galenic medicine. The research of the Académie on ginseng was greatly advanced, owing much to the reports and samples sent from China and Canada by Jartoux, Sarrazin, and Lapitau. From the early 18th century, the conservative attitude of the University of Paris, which was a stronghold of

Full Text Available A negação da chamada plenitudo potestatis ao papa, por parte do menorita Guilherme de Ockham, insere-se, do ponto de vista de seu contexto histórico, no amplo movimento, processado a partir da transição do século XIII para o XIV, de declínio do Império enquanto poder universal, somado à progressiva busca pela laicização das questões de Estado, tendo como resultado a mudança na concepção da autoridade papal. Dessa forma, querelas ocorridas entre o regnum e o sacerdotium passariam a opor à autoridade papal a figura de monarcas em franca ascensão (caso da disputa entre Bonifácio VIII e Filipe IV, da França. Além disso, as novas soluções configuravam-se antes como favoráveis aos poderes civis que à autoridade papal. Um aspecto significativo da ampliação do poder e prestígio das monarquias foi a própria transferência do papado para a cidade francesa de Avinhão, a partir de 1309, sob o papa Clemente V. O referido pontífice atendia à expectativa do mesmo rei da França, Filipe IV, o qual deveria, assim como seus sucessores, ao longo dos anos seguintes, utilizar-se da instituição eclesiástica com a finalidade de opor-se a seus inimigos políticos. Um dos pontos culminantes dessa aliança ter-se-ia dado sob o pontificado de Clemente VI (1342-1352, que apoiou o monarca francês Filipe VI contra seu primo e rei da Inglaterra Eduardo III, na Guerra dos Cem Anos; e ainda, sua hostilidade concorreu para a queda do imperador Luís da Baviera. Pretende-se, nesse trabalho, avaliar as relações do papado avinhonense com os poderes civis (os reinos da França e da Inglaterra e o Império, entre fins da década de 30 e inícios da década de 40 do século XIV. Para tanto, partiremos das obras Pode um príncipe, Consulta sobre uma questão matrimonial e Sobre o poder dos imperadores e dos papas, de Guilherme de Ockham.The denial of the so-called pope's plenitude potestatis by the English Franciscan William of Ockham belongs

Crossing symmetry in Alpha space

CERN. Geneva

2017-01-01

The conformal bootstrap program aims to catalog all conformal field theories (second-order phase transitions) in D dimensions. Despite its ambitious scope much progress has been made over the past decade, e.g. in computing critical exponents for the 3D O(N) models to high precision. At this stage, analytic methods to explore the CFT landscape are not as well developed. In this talk I will describe a new mathematical framework for the bootstrap known as "alpha space", which reduces crossing symmetry to a set of integral equations.

Newton's constant from a minimal length: additional models

International Nuclear Information System (INIS)

Sahlmann, Hanno

2011-01-01

We follow arguments of Verlinde (2010 arXiv:1001.0785 [hep-th]) and Klinkhamer (2010 arXiv:1006.2094 [hep-th]), and construct two models of the microscopic theory of a holographic screen that allow for the thermodynamical derivation of Newton's law, with Newton's constant expressed in terms of a minimal length scale l contained in the area spectrum of the microscopic theory. One of the models is loosely related to the quantum structure of surfaces and isolated horizons in loop quantum gravity. Our investigation shows that the conclusions reached by Klinkhamer regarding the new length scale l seem to be generic in all their qualitative aspects.

La determinación del volumen de la mama que posee la paciente y del volumen que quisiera tener se ve limitada por inconvenientes técnicos y por la poca precisión en la interpretación psicosocial de las mediciones y cálculos que se pueden hacer. El objetivo de este estudio ha sido desarrollar un sistema que partiendo de las medidas intrínsecas del sujetador permita relacionar el volumen de la mama de la paciente con el volumen de la copa del sujetador que desea y con la prótesis necesaria para conseguirlo. Tomamos medidas antropomórficas del tórax y de las mamas en 100 mujeres de entre 18 y 32 años de edad, candidatas a una mamoplastia de aumento y evaluamos la talla del sujetador que usaban y el que deseaban usar tras la cirugía. Estudiamos los volúmenes de las copas de los sujetadores en función del sistema de calibración comercial de tallas. Se plantearon a las pacientes dos preguntas en relación con la talla del sujetador: ¿qué contorno y copa de sujetador usa? y ¿qué contorno y copa de sujetador quiere usar? Las respuestas se relacionaron con sus medidas antropomórficas y se buscó implantar las prótesis mamarias que, complementando el volumen de su mama, consiguieran rellenar la copa del sujetador que deseaban.

PREFACE Proceedings of the XIV International Conference on Small-Angle Scattering, SAS-2009

King, Stephen; Terrill, Nicholas

2010-10-01

The XIV International Conference on Small-Angle Scattering, SAS-2009, was held in Oxford UK, 13-18 September 2009, and was jointly organised under the auspices of the International Union of Crystallography Commission on SAS by a team from the Diamond Light Source and the ISIS Pulsed Neutron Source - their first such joint venture - with help from the UK Science and Technology Facilities Council. It was the first time that this long running and successful series of conferences on the application, science and technology of small-angle scattering techniques had been staged in the UK. The UK has a proud heritage in small-angle scattering: as home to one of the world's first SANS instruments (at AERE Harwell), as the site of the world's first 2nd generation X-ray Synchrotron (the SRS at Daresbury with its suite of SAXS beamlines), and latterly as the location of the world's most successful pulsed source SANS instrument. Indeed, 2009 also marked the 25th Anniversary of neutron operations at ISIS and the opening of a Second Target Station. Whilst the SRS ceased operations in 2008, its mantle has been inherited by the Diamond synchrotron. Many delegates took the opportunity to visit both Diamond and ISIS during a conference excursion. Despite the prevailing global economic downturn, we were delighted that 434 delegates from 32 different countries were able to attend SAS-2009; two-thirds were drawn from the UK, Germany, Japan, the USA and France, but there were also sizeable contingents from Australia, Korea, Taiwan and South America. In many ways this geographical spread reflects the present and emerging distribution, respectively, of 3rd generation X-ray synchrotrons and high-flux neutron sources, although the scope of the conference was not solely limited to these probes. Financial support from the IUCr enabled us to grant bursaries to attend SAS-2009 to 12 delegates from emerging countries (Algeria, Argentina, Brazil, India, Nepal, Romania, Russia and the Ukraine).

Quantum-electrodynamic influences on the lifetime of metastable states

International Nuclear Information System (INIS)

Brenner, G.

2007-01-01

High-precision lifetime measurements of the metastable 1s 2 2s 2 2p 2 P 0 3/2 level in boronlike Ar XIV and the 3s 2 2p 2 P 0 3/2 level in aluminumlike Fe XIV were performed at the Heidelberg electron beam ion trap (HD-EBIT). The lifetimes were inferred by monitoring their optical decay curves resulting from the magnetic dipole (M1) transition 1s 2 2s 2 2p 2 P 0 3/2 - 2 P 0 1/2 and 3s 2 3p 2 P 0 3/2 - 2 P 0 1/2 to the ground state configuration with transition wavelengths of 441.256 nm and 530.29 nm, respectively. Possible systematic error sources were investigated by studying the dependence of the decay times of the curves on various trapping conditions with high statistical significance. A new trapping scheme for lifetime measurements at an EBIT has been applied and allowed to reach an unprecedented precision in the realm of lifetime determinations on highly charged ions. The results of 9.573(4)( +12 -5 ) ms (stat)(syst) for Ar XIV and 16.726(10)(+17) ms (stat)(syst) for Fe XIV with a relative accuracy of 0.14% and 0.13%, respectively, make these measurements for the first time sensitive to quantum electrodynamic effects like the electron anomalous magnetic moment (EAMM). The results, improving the accuracy of previous measurements by factors of 10 and 6, respectively, show a clear discrepancy of about 3σ and 4σ to the trend of existing theoretical models, which in almost all cases predict a shorter lifetime, when adjusted for the EAMM. The obvious disagreement between experimental results and the predictions points at the incompleteness of the theoretical models used. (orig.)

2017-11-01

This technical report revisits the analysis of family-wise error rates in statistical parametric mapping-using random field theory-reported in (Eklund et al. []: arXiv 1511.01863). Contrary to the understandable spin that these sorts of analyses attract, a review of their results suggests that they endorse the use of parametric assumptions-and random field theory-in the analysis of functional neuroimaging data. We briefly rehearse the advantages parametric analyses offer over nonparametric alternatives and then unpack the implications of (Eklund et al. []: arXiv 1511.01863) for parametric procedures.

The X-ray nova A0620-00 has been studied with the Ariel V crystal spectrometer/polarimeter for the presence of X-ray lines and polarization. Upper limits are obtained for the Si XIV, S XV and S XVI lines to a level of less than 2 eV at 3 sigma for the sulphur lines and 3.6 eV for Si XIV. No linear polarization is observed to a level of 2 per cent at 2.6 keV. These results are interpreted in terms of an accretion disk model for the source, in which the electron scattering depth tausub(es) approximately 20, and constraints are given on the disk geometry.

Recently a new class of 1/8-BPS regular geometries in type IIB string theory was constructed in arXiv:1503.01463. In this paper we provide a precise description of the semiclassical states dual, in the AdS/CFT sense, to these geometries. In explicit examples we show that the holographic 1-point functions and the Ryu-Takayanagi’s Entanglement Entropy for a single small interval match the corresponding CFT calculations performed by using the proposed dual states. We also discuss several new examples of such precision holography analysis in the 1/4-BPS sector and provide an explicit proof that the small interval derivation of the Entanglement Entropy used in arXiv:1405.6185 is fully covariant.

High-energy physicists worldwide rely on online resources such as SPIRES and arXiv to perform gather research and share their own publications. SPIRES is a tool designed to search the literature within high-energy physics, while arXiv provides the actual full-text documents of this literature. In high-energy physics, papers are often ranked according to the number of citations they acquire - meaning the number of times a later paper references the original. This paper investigates the correlation between the number of times a paper is clicked in order to be downloaded and the number of citations it receives following the click. It explores how physicists truly read what they cite.

Inflation with improved D3-brane potential and the fine tunings associated with the model

International Nuclear Information System (INIS)

Ali, Amna; Sami, M.; Deshamukhya, Atri; Panda, Sudhakar

2011-01-01

We revisit our earlier investigations of the brane-antibrane inflation in a warped deformed conifold background, reported in Phys. Lett. B 674, 131 (2009), where now we include the contributions to the inflation potential arising from imaginary anti-self-dual (IASD) fluxes including the term with irrational scaling dimension discovered recently in arXiv:0912.4268 and arXiv:1001.5028. We observe that these corrections to the effective potential help in relaxing the severe fine tunings associated with the earlier analysis. Required number of e-folds, observational constraint on COBE normalization and low value of the tensor to scalar ratio are achieved which is consistent with WMAP seven years data. (orig.)

Janus field theories from non-linear BF theories for multiple M2-branes

We integrate the nonpropagating B μ gauge field for the non-linear BF Lagrangian describing N M2-branes which includes terms with even number of the totally antisymmetric tensor M IJK in arXiv:0808.2473 and for the two-types of non-linear BF Lagrangians which include terms with odd number of M IJK as well in arXiv:0809:0985. For the former Lagrangian we derive directly the DBI-type Lagrangian expressed by the SU(N) dynamical A μ gauge field with a spacetime dependent coupling constant, while for the low-energy expansions of the latter Lagrangians the B μ integration is iteratively performed. The derived Janus field theory Lagrangians are compared.

Full Text Available Las predicciones sobre aprendizaje derivadas de los modelos de complejidad social y forrajeo central, fueron sometidas a prueba usando una especie de abeja social (Apis mellifera y una especie de abeja solitaria (Osmia lignaria, a las cuales les fue ofrecida una tarea de aprendizaje en el contexto de forrajeo de néctar. Ambas especies fueron expuestas a las mismas condiciones de forrajeo, donde 1 se cambió únicamente la molaridad de la recompensa entre las formas florales, y 2 se cambió únicamente el volumen de la recompensa. Los experimentos se hicieron con parches de flores artificiales utilizando dos variedades de color floral (azul y blanco para estandarizar las recompensas de néctar en cada situación experimental. Aunque las abejas sociales aprendieron más rápido que las solitarias cuando se les presentó un problema de diferencia de molaridad en la recompensa, no hubo una diferencia significativa con respecto al aprendizaje de diferencias en volumen de néctar. Adicionalmente, la tasa a la cual O. lignaria aprendió diferencias en el volumen de la recompensa, no difirió de la tasa a la cual A. melifera aprendió las diferencias de concentración del néctar. Los resultados no apoyan las predicciones de la teoría de la complejidad social, pero soportan las del modelo de forrajeo central.

Full Text Available Se propone un modelo matemático para predecir el crecimiento de la zona de mezcla o frente de contaminación que se genera entre combustibles derivados del petróleo como consecuencia de su transporte secuencial por poliductos. Dicho modelo se construye a partir de conceptos básicos de fenómenos de transporte, introduciendo un coeficiente efectivo de transferencia de masa que tiene en cuenta el mecanismo de difusión pura y su aporte a la convección. El modelo, una vez ajustado con datos de campo, se aplica para predecir el volumen del frente de contaminación y para analizar el efecto de variables como la longitud y el diámetro del poliducto, y la tasa de flujo sobre el crecimiento del volumen del frente.

In this paper, we report on the radiation resistance of 50-micron thick LGAD detectors manufactured at the Fondazione Bruno Kessler employing several different doping combinations of the gain layer. LGAD detectors with gain layer doping of Boron, Boron low-diffusion, Gallium, Carbonated Boron and Carbonated Gallium have been designed and successfully produced. These sensors have been exposed to neutron fluences up to $\\phi_n \\sim 3 \\cdot 10^{16}\\; n/cm^2$ and to proton fluences up to $\\phi_p \\sim 9\\cdot10^{15}\\; p/cm^2$ to test their radiation resistance. The experimental results show that Gallium-doped LGADs are more heavily affected by initial acceptor removal than Boron-doped LGAD, while the presence of Carbon reduces initial acceptor removal both for Gallium and Boron doping. Boron low-diffusion shows a higher radiation resistance than that of standard Boron implant, indicating a dependence of the initial acceptor removal mechanism upon the implant width. This study also demonstrates that proton irradiati...

The Planck satellite provides a set of all-sky maps at nine frequencies from 30 GHz to 857 GHz. Planets, minor bodies, and diffuse interplanetary dust emission (IPD) are all observed. The IPD can be separated from Galactic and other emissions because Planck views a given point on the celestial sphere multiple times, through different columns of IPD. We use the Planck data to investigate the behaviour of zodiacal emission over the whole sky at sub-millimetre and millimetre wavelengths. We fit the Planck data to find the emissivities of the various components of the COBE zodiacal model -- a diffuse cloud, three asteroidal dust bands, a circumsolar ring, and an Earth-trailing feature. The emissivity of the diffuse cloud decreases with increasing wavelength, as expected from earlier analyses. The emissivities of the dust bands, however, decrease less rapidly, indicating that the properties of the grains in the bands are different from those in the diffuse cloud. We fit the small amount of Galactic emission seen t...

Super-cool Dark Matter arXiv

CERN Document Server

Hambye, Thomas; Teresi, Daniele

In dimension-less theories of dynamical generation of the weak scale, the Universe can undergo a period of low-scale inflation during which all particles are massless and super-cool. This leads to a new mechanism of generation of the cosmological Dark Matter (DM) relic density: super-cooling can easily suppress the amount of DM to the desired level. This is achieved for TeV-scale DM, if super-cooling ends when quark condensates form at the QCD phase transition. Along this scenario, the baryon asymmetry can be generated either at the phase transition or through leptogenesis. We show that the above mechanism takes place in old and new dimension-less models.

Riemann-Theta Boltzmann Machine arXiv

CERN Document Server

Krefl, Daniel; Haghighat, Babak; Kahlen, Jens

A general Boltzmann machine with continuous visible and discrete integer valued hidden states is introduced. Under mild assumptions about the connection matrices, the probability density function of the visible units can be solved for analytically, yielding a novel parametric density function involving a ratio of Riemann-Theta functions. The conditional expectation of a hidden state for given visible states can also be calculated analytically, yielding a derivative of the logarithmic Riemann-Theta function. The conditional expectation can be used as activation function in a feedforward neural network, thereby increasing the modelling capacity of the network. Both the Boltzmann machine and the derived feedforward neural network can be successfully trained via standard gradient- and non-gradient-based optimization techniques.

arXiv Minimal Fundamental Partial Compositeness

CERN Document Server

Cacciapaglia, Giacomo; Sannino, Francesco; Thomsen, Anders Eller

Building upon the fundamental partial compositeness framework we provide consistent and complete composite extensions of the standard model. These are used to determine the effective operators emerging at the electroweak scale in terms of the standard model fields upon consistently integrating out the heavy composite dynamics. We exhibit the first effective field theories matching these complete composite theories of flavour and analyse their physical consequences for the third generation quarks. Relations with other approaches, ranging from effective analyses for partial compositeness to extra dimensions as well as purely fermionic extensions, are briefly discussed. Our methodology is applicable to any composite theory of dynamical electroweak symmetry breaking featuring a complete theory of flavour.

2007-09-01

The fourteenth conference in the Sensors and their Applications series took place at the Liverpool John Moores University in Liverpool, UK from 11-13 September 2007. The event was organised by the Instrument Science and Technology Group of the Institute of Physics. Previous conferences in this series were held in Manchester (1983 and 1993), Southampton (1985 and 1998), Cambridge (1987), Canterbury (1989), Edinburgh (1991), Dublin (1995), Glasgow (1997), Cardiff (1999), London (2001), Limerick (2003) and Chatham (2005). The event provided a forum for academic researchers and industrial engineers working in all areas of sensors, instrumentation and measurement to update themselves on the latest technical developments and applications, share knowledge and stimulate new ideas. The third decade of this conference series continues to highlight new technologies and applications as the sensor market benefits from enhanced signal processing power and wireless networking. Through presentation of oral papers, discussions at exhibited posters and informal exchanges of ideas, the conference continues to provide excellent knowledge transfer and networking opportunities. The high quality programme, headlined by notable contributions from invited speakers, included microsensors, automotive sensors, gas sensing, non-destructive inspection, food and healthcare, sensor signal processing, wireless sensing, modelling and imaging techniques. As in previous years, this conference was particularly highlighted by a large number of sensor applications papers. We take this opportunity to thank all of those who have contributed to the event. Our thanks also go to our colleagues in the Instrument Science and Technology Group for their support and encouragement, particularly in the refereeing of papers, and to the Sensors and Instrumentation Knowledge Transfer Network. Special thanks go to Claire Garland from the Conferences Department of the Institute of Physics and the local team at Liverpool John Moores University who have expertly managed the planning and organising of this Conference. We hope that these conference proceedings will provide a technical insight into the development of sensors and their applications during 2007.

Aspects of Weyl Supergravity arXiv

Ferrara, Sergio; Lust, Dieter

In this paper we study the spectrum of all conformal, ${\\cal N}$-extended supergravities (${\\cal N}=1,2,3,4$) in four space-time dimensions. When these theories are obtained as massless limit of Einstein plus Weyl$^2$supergravity, the appropriate counting of the enhanced gauge symmetries allow us to derive the massless spectrum which consist of a dipole ghost graviton multiplet, a ${\\cal N}$-fold tripole ghost gravitino, the third state belonging to a spin 3/2 multiplet and a residual vector multiplet present for non-maximal ${\\cal N}<4$ theories. These theories are not expected to have a standard gravity holographic dual in five dimensions.

Full Text Available Meditação sobre a tragédia humana, as narrativas tacitianas tendem não somente a ordenar e a expor os fatos mas tambám, e sobretudo, a sugerir planos de fundo psicológicos que se escondem por detrás da realidade sensível. Tacito – sabe-se – organiza suas narrativas com a finalidade de provocar na consciência de seu leitor uma série de emoções capazes de engendrar um estado de sensibilidade que o predispõe a compreender melhor as causas dos acontecimentos que Roma conheceu e que precipitaram sua decadência. Para atingir esse fim ele recorre a apresentação poética. Esta, ao mesmo tempo em que dá à narrativa de Tácito certa beleza, participa da estratégia de persuasão, tocando a imaginação dos leitores. Assim, a frase dos Anais XIV, 5, 1 e, sem dúvida, um exemplo entre tantos outros que mostram que, em Tácito, a poesia tem um conteúdo de pensamento que exprime ou aproxima a verdade histórica. E também um belo exemplo que, na literatura latina, mostra como é difícil a tarefa de um historiador pós-clássico, de unir a realidade histórica ao cuidado com o belo e ao respeito a complexidade dos acontecimentos históricos. Nas narrativas de Tácito, frequentemente marcada pela dimensão dramática, a apresentação poética dos acontecimentos entra na estratégia da persuasão que incita os leitores a melhor apreender o sentido oculto da história.

Motion of charged particle in Reissner-Nordstroem spacetime. A Jacobi-metric approach

2017-11-15

The present work discusses motion of neutral and charged particles in Reissner-Nordstroem spacetime. The constant energy paths are derived in a variational principle framework using the Jacobi metric which is parameterized by conserved particle energy. Of particular interest is the case of particle charge and Reissner-Nordstroem black hole charge being of same sign, since this leads to a clash of opposing forces - gravitational (attractive) and Coulomb (repulsive). Our paper aims to complement the recent work of Pugliese et al. (Eur Phys J C 77:206. arXiv:1304.2940, 2017; Phys Rev D 88:024042. arXiv:1303.6250, 2013). The energy dependent Gaussian curvature (induced by the Jacobi metric) plays an important role in classifying the trajectories. (orig.)

Fast decoder for local quantum codes using Groebner basis

Science.gov (United States)

Haah, Jeongwan

2013-03-01

Based on arXiv:1204.1063. A local translation-invariant quantum code has a description in terms of Laurent polynomials. As an application of this observation, we present a fast decoding algorithm for translation-invariant local quantum codes in any spatial dimensions using the straightforward division algorithm for multivariate polynomials. The running time is O (n log n) on average, or O (n2 log n) on worst cases, where n is the number of physical qubits. The algorithm improves a subroutine of the renormalization-group decoder by Bravyi and Haah (arXiv:1112.3252) in the translation-invariant case. This work is supported in part by the Insitute for Quantum Information and Matter, an NSF Physics Frontier Center, and the Korea Foundation for Advanced Studies.

In diesem Paper wird ein neues Verfahren zur semi-automatischen Orbita-Segmentierung mit minimalem Interaktionsaufwand vorgestellt. Die Ergebnisse der semi-automatischen Segmentierung haben wir mit der manuellen Segmentierung eines Experten in Bezug auf Volumen, Überlappungsmaße und Segmentierungszeit verglichen. Die Abweichung zwischen manueller und semi-automatischer Segmentierung beträgt durchschnittlich 3,29% des Volumens. Im Vergleich zur manuellen Segmentierung liegen die Ergebnisse deutlich unter den Schwankungen der interindividuellen Variabilität, daher ist dieses Verfahren der manuellen Segmentierung vorzuziehen. In unserer künftigen Arbeit möchten wir den Interaktionsaufwand sowie den Segmentierungsfehler weiter reduzieren. Zudem sollen die Einsatzmöglichkeiten des Verfahrens zur präoperativen Planung von Orbitarekonstruktionen evaluiert werden.

Full Text Available El artículo hace un análisis de la relación entre crecimiento económico y medio ambiente para las 32 entidades federativas de la República Mexicana. La curva ambiental de Kuznets (CAK sugiere la existencia de una relación entre crecimiento económico y medio ambiente. A medida que las economías disfrutan un mayor crecimiento económico, se presenta una degradación ambiental y una vez que se alcanza cierto crecimiento, aumenta la disponibilidad a pagar por la conservación del medio ambiente. En el caso de la economía mexicana, al aplicar el análisis de convergencia por medio de datos de corte transversal y datos de panel, se encuentra que: i existe β convergencia en árboles plantados, áreas naturales protegidas, licencias ambientales y volumen de tratamiento de aguas en sus niveles per capita; ii no hay evidencia de σ-convergencia en las variables medio ambientales para los estados de la economía mexicana, excepto en áreas naturales protegidas, árboles plantados y licencias ambientales; iii no existe una relación entre crecimiento económico y aumento en el cuidado de las variables medioambientales, excepto para el volumen de recolección de basura y el volumen de aguas residuales; iv los resultados sugieren que el medio ambiente no está entre las prioridades de la economía mexicana de acuerdo con la hipótesis de la CAK.

Full Text Available Objetivo. Determinar el efecto de las variaciones de la oferta diaria de forraje sobre la producción y calidad de la leche. Materiales y métodos. Determinando el área de oferta diaria mediante un sistema de posicionamiento global y empleando la técnica de doble muestreo para medir producción de biomasa previa y posterior al pastoreo, se estimó su consumo diario por diferencia agronómica. Se estimaron variaciones dentro y entre fincas para los parámetros evaluados. Se estableció el grado de asociación entre las variaciones diarias en la oferta con el consumo, el volumen y calidad de la leche. Resultados. Los resultados evidenciaron asociación entre variaciones de oferta diaria y consumo de forraje (R2=0.65 y la variación en volumen diario de leche (R2=0.45. Las variaciones en grasa no mostraron relación con cambios en la oferta (R2=0.0 y sus valores fueron asociados a la relación forraje/suplemento (R2=0.52. Las variaciones en proteína tuvieron menor asociación con las variaciones en la oferta (R2=0.17 y mayor con el consumo de materia seca (R2=0.34. Conclusiones. Los resultados sugieren que variaciones en la oferta forrajera explican en mayor grado las variaciones en el consumo de materia seca con unefecto directo sobre el volumen de leche y en menor grado sobre las variaciones en su composición.

Full Text Available El cativo (Prioria copaifera G. forma bosques dominados por la especie llamados cativales. Durante más de 70 años el cativo ha sido la base principal de la industria maderera en el Darién colombiano, siendo, por su alta productividad y dominancia uno de los bosques tropicales más fáciles de ordenar sosteniblemente. El propósito de esta investigación es modelar el crecimiento del diámetro y el volumen del cativo en función de la edad así como las tasas instantáneas, medias y relativas, empleando anillos de crecimiento. La anualidad de los anillos se demostró usando el efecto de las bombas nucleares y mediante cofechado. Con base en los anillos de crecimiento radiales se modelo el crecimiento del diámetro y del volumen. Esta especie alcanza 40cm de diámetro en 90 años y presenta crecimiento medio de 0.31cm/año. El lapso vital de la especie es de aproximadamente 614 años. El incremento corriente anual máximo del volumen a los 90 años es 0.033m3/año, e iguala al incremento medio a los 145 años con 0.018m3/año. La tasa media de crecimiento absoluta es 0.021m3/año. Los resultados aquí obtenidos sirven como base técnica para el manejo sostenible de los cativales.

TMD splitting functions in kT factorization. The real contribution to the gluon-to-gluon splitting

Hentschinski, M.; Kusina, A.; Kutak, K.; Serino, M.

2018-01-01

We calculate the transverse momentum dependent gluon-to-gluon splitting function within k T -factorization, generalizing the framework employed in the calculation of the quark splitting functions in Hautmann et al. (Nucl Phys B 865:54-66, arXiv:1205.1759, 2012), Gituliar et al. (JHEP 01:181, arXiv:1511.08439, 2016), Hentschinski et al. (Phys Rev D 94(11):114013, arXiv:1607.01507, 2016) and demonstrate at the same time the consistency of the extended formalism with previous results. While existing versions of k T factorized evolution equations contain already a gluon-to-gluon splitting function i.e. the leading order Balitsky-Fadin-Kuraev-Lipatov (BFKL) kernel or the Ciafaloni-Catani-Fiorani-Marchesini (CCFM) kernel, the obtained splitting function has the important property that it reduces both to the leading order BFKL kernel in the high energy limit, to the Dokshitzer-Gribov-Lipatov-Altarelli-Parisi (DGLAP) gluon-to-gluon splitting function in the collinear limit as well as to the CCFM kernel in the soft limit. At the same time we demonstrate that this splitting kernel can be obtained from a direct calculation of the QCD Feynman diagrams, based on a combined implementation of the Curci-Furmanski-Petronzio formalism for the calculation of the collinear splitting functions and the framework of high energy factorization.

A theoretical and experimental research is conducted in order to determine the labyrinth seal forces, as well as the stiffness and damping coefficients for straight, convergent, divergent, and combined shapes on turbine and compressor rotors. The mathematical model is deduced on the basis of the single volume method and its solution is obtained by the perturbation procedure. The validation is achieved with published results. Experimental work carried out on a test bench is described in the text. This involved labyrinth seals with straight, convergent, and divergent profiles, as the published information relating to mixed type is sufficient to perform the evaluation. The conclusions demonstrate that the model is able to predict and determine the performance of labyrinth seals based on forces and rotordynamic coefficients for static and dynamic motions. Finally, tests on real steam turbines of 300 MW are recommended. In this case the high pressures and use of wheels with strips on the periphery and supported by the upper part of blades, increase the susceptibility of self excited subsynchronous vibrations.

El modelo matematico propuesto se deduce a partir del metodo de un solo volumen y su solucion se obtiene a traves de metodos perturbatorios.

Detecting signatures of cosmological recombination and reionization in the cosmic radio background

Subrahmanyan, Ravi; Shankar Narayana Rao, Udaya; Sathyanarayana Rao, Mayuri; Singh, Saurabh

Evolution of the baryons during the Epochs of cosmological Recombination and Reionization has left traces in the cosmic radio background in the form of spectral distortions (Sunyaev & Chluba 2008 Astron. Nachrichten, 330, 657; Pritchard & Loeb 2012 Rep Prog Phys 75(8):086901). The spectral signature depends on the evolution in the ionization state in hydrogen and helium and on the spin temperature of hydrogen. These probe the physics of energy release beyond the last scattering surface at redshifts exceeding 1090 and the nature of the first sources and gas evolution down to redshift about 6. The spectral distortions are sensitive to the nature of the first stars, ultra-dwarf galaxies, accreting compact objects, and the evolving ambient radiation field: X-rays and UV from the first sources. Detection of the all-sky or global spectral distortions in the radio background is hence a probe of cosmological recombination and reionization.We present new spectral radiometers that we have purpose designed for precision measurements of spectral distortions at radio wavelengths. New antenna elements include frequency independent and electrically small fat-dipole (Raghunathan et al. 2013 IEEE TAP, 61, 3411) and monopole designs. Receiver configurations have been devised that are self-calibratable (Patra et al. 2013 Expt Astron, 36, 319) so that switching of signal paths and of calibration noise sources provide real time calibration for systematics and receiver noise. Observing strategies (Patra et al. arXiv:1412.7762) and analysis methods (Satyanarayana Rao et al. arXiv:1501.07191) have been evolved that are capable of discriminating between the cosmological signals and the substantially brighter foregrounds. We have also demonstrated the value of system designs that exploit advantages of interferometer detection (Mahesh et al. arXiv:1406.2585) of global spectral distortions.Finally we discuss how the Square Kilometer Array stations may be outfitted with precision spectral

Quantum-electrodynamic influences on the lifetime of metastable states; Quantenelektrodynamische Einfluesse auf die Lebensdauer metastabiler Zustaende

High-precision lifetime measurements of the metastable 1s{sup 2}2s{sup 2}2p{sup 2}P{sup 0}{sub 3/2} level in boronlike Ar XIV and the 3s{sup 2}2p {sup 2}P{sup 0}{sub 3/2} level in aluminumlike Fe XIV were performed at the Heidelberg electron beam ion trap (HD-EBIT). The lifetimes were inferred by monitoring their optical decay curves resulting from the magnetic dipole (M1) transition 1s{sup 2}2s{sup 2}2p{sup 2}P{sup 0}{sub 3/2}-{sup 2}P{sup 0}{sub 1/2} and 3s{sup 2}3p {sup 2}P{sup 0}{sub 3/2}-{sup 2}P{sup 0}{sub 1/2} to the ground state configuration with transition wavelengths of 441.256 nm and 530.29 nm, respectively. Possible systematic error sources were investigated by studying the dependence of the decay times of the curves on various trapping conditions with high statistical significance. A new trapping scheme for lifetime measurements at an EBIT has been applied and allowed to reach an unprecedented precision in the realm of lifetime determinations on highly charged ions. The results of 9.573(4)({sup +12}{sub -5}) ms (stat)(syst) for Ar XIV and 16.726(10)(+17) ms (stat)(syst) for Fe XIV with a relative accuracy of 0.14% and 0.13%, respectively, make these measurements for the first time sensitive to quantum electrodynamic effects like the electron anomalous magnetic moment (EAMM). The results, improving the accuracy of previous measurements by factors of 10 and 6, respectively, show a clear discrepancy of about 3{sigma} and 4{sigma} to the trend of existing theoretical models, which in almost all cases predict a shorter lifetime, when adjusted for the EAMM. The obvious disagreement between experimental results and the predictions points at the incompleteness of the theoretical models used. (orig.)

We study complexified Harmonic Oscillator with a position-dependent mass, termed as Complex Exotic Oscillator (CEO). The complexification induces a gauge invariance [A.V. Smilga, J. Phys. A 41 (2008) 244026, (arXiv:0706.4064); A. Mostafazadeh, J. Math. Phys. 43 (2002) 205; A. Mostafazadeh, J. Math. Phys. 43 (2002) 2814; A. Mostafazadeh, J. Math. Phys. 43 (2002) 3944]. The role of PT-symmetry is discussed from the perspective of classical trajectories of CEO for real energy. Some trajectories of CEO are similar to those for the particle in a quartic potential in the complex domain [C.M. Bender, S. Boettcher, P.N. Meisinger, J. Math. Phys. 40 (1999) 2201; C.M.

The blow-up rate estimate for the solution to a semilinear parabolic equation u=Δu+V(x)|u in Ω×(0,T) with 0-Dirichlet boundary condition is obtained. As an application, it is shown that the asymptotic behavior of blow-up time and blow-up set of the problem with nonnegative initial data u(x,0)=Mφ(x) as M goes to infinity, which have been found in [C. Cortazar, M. Elgueta, J.D.

2009-01-01

In the paper [R.-G. Cai, L.-M. Cao, Y.-P. Hu, (arXiv: 0809.1554)], the scalar particles' Hawking radiation from the apparent horizon of Friedmann-Robertson-Walker (FRW) universe was investigated by using the tunneling formalism. They obtained the Hawking temperature associated with the apparent horizon, which was extensively applied in investigating the relationship between the first law of thermodynamics and Friedmann equations. In this Letter, we calculate fermions' Hawking radiation from the apparent horizon of FRW universe via tunneling formalism. Applying WKB approximation to the general covariant Dirac equation in FRW spacetime background, the radiation spectrum and Hawking temperature of apparent horizon are correctly recovered, which supports the arguments presented in the paper [R.-G.

Solitonic excitations in collisions of superfluid nuclei a qualitatively new phenomenon distinct from the Josephson effect

Science.gov (United States)

Sekizawa, Kazuyuki; Wlazłowski, Gabriel; Magierski, Piotr

2017-11-01

Recently, we have reported a novel role of pairing in low-energy heavy ion reactions at energies above the Coulomb barrier, which may have a detectable impact on reaction outcomes, such as the kinetic energy of fragments and the fusion cross section [arXiv:1611.10261, arXiv:1702.00069]. The phenomenon mimics the one studied experimentally with ultracold atomic gases, where two clouds of fermionic superfluids with different phases of the pairing fields are forced to merge, inducing various excitation modes of the pairing field. Although it originates from the phase difference of the pairing fields, the physics behind it is markedly different from the so-called Josephson effect. In this short contribution, we will briefly outline the results discussed in our recent papers and explain relations with the field of ultracold atomic gases.

Full Text Available Las técnicas de indentación poseen una gran versatilidad que permite evaluar propiedades mecánicas en volúmenes inferiores a 0.001 mm3, hasta volúmenes del orden de los mm3, útil tanto en materiales compuestos como en volumen. Este artículo hace una revisión general de los fundamentos de éstas técnicas. También se muestran algunas de las dificultades que surgen cuando éstas son aplicadas a la medición de propiedades mecánicas de materiales cerámicos, tales como su dureza tenacidad a la fractura, módulo de elasticidad y adherencia de capas cerámicas en sustratos metálicos. Para esto se utilizan algunos materiales cerámicos en volumen como alúmina Al2O3, Titanato de Bario BaTiO3 y capas TiN depositadas sobre acero M2.

Full Text Available El Método de los Elementos Finitos asistido por ordenador es una herramienta muy extendida en ingeniería. En ciertas aplicaciones, se precisa modificar la malla del modelo a lo largo del proceso de simulación, lo que se conoce como remallado. En estos casos, además, suele ser necesario realizar mediciones en el modelo de elementos finitos, como por ejemplo calcular el volumen de ciertas regiones del mismo. Los paquetes comerciales disponibles en la actualidad permiten satisfacer algunas de estas necesidades, aunque adolecen de ciertas limitaciones. En este trabajo se presenta una aplicación desarrollada en el código propio de MatlabQc, que permite el cálculo aproximado del volumen de una región del espacio comprendida entre una malla de elementos finitos cuadriláteros lineales y otra malla topológicamente equivalente a la anterior, esta última obtenida a través de un proceso de remallado.

To assess the effect of a shrinking rectal balloon implant (RBI) on the anorectal dose and complication risk during the course of moderately hypofractionated prostate radiotherapy. In 15 patients with localized prostate cancer, an RBI was implanted. A weekly kilovolt cone-beam computed tomography (CBCT) scan was acquired to measure the dynamics of RBI volume and prostate-rectum separation. The absolute anorectal volume encompassed by the 2 Gy equieffective 75 Gy isodose (V{sub 75Gy}) was recalculated as well as the mean anorectal dose. The increase in estimated risk of grade 2-3 late rectal bleeding (LRB) between the start and end of treatment was predicted using nomograms. The observed acute and late toxicities were evaluated. A significant shrinkage of RBI volumes was observed, with an average volume of 70.4% of baseline at the end of the treatment. Although the prostate-rectum separation significantly decreased over time, it remained at least 1 cm. No significant increase in V{sub 75Gy} of the anorectum was observed, except in one patient whose RBI had completely deflated in the third week of treatment. No correlation between mean anorectal dose and balloon deflation was found. The increase in predicted LRB risk was not significant, except in the one patient whose RBI completely deflated. The observed toxicities confirmed these findings. Despite significant decrease in RBI volume the high-dose rectal volume and the predicted LRB risk were unaffected due to a persistent spacing between the prostate and the anterior rectal wall.

Full Text Available This article compiles a large part of the copious documentation concerning the cathedral, the Chapter of the Augustinian canons and the bishopric of Tortosa, investigated by the author in de registries of the Royal Chancery and the archives of the Royal Property Record Office of Barcelona. These documents, which go from the second half of the XIV century to the beginning of the XV, complete the documentation from the Chapter Archive of the Cathedral of Tortosa. In the first part the author studies the works undertaken to build the gothic cathedral, identifies some of its masters and their role in the construction, as well as their relations with the Chapter of the Cathedral and other master builders at that time. It is a very close approach to those works and the periods of greater and lesser activity, which apparently reflect the different times undergone by the Chapter. The second part focuses on the Chapter of the Cathedral and its different dignitaries and canons, its internal matters, the conflicts created by external interference as well as the internal tensions aroused by royal interference, the Pope's lack of interest and the neutrality of King Pere III concerning the Schism of Western Christianity. The defense by the Chapter of its rights under the administration, imposed on them, of Pedro de Luna (1399-1403 is analysed in detail and results in an appendix of documents.[fr] Dans la première partie de l'article on y étudie l'activité constructive de la cathédrale gothique, on y fait connaître l'identité de quelques-uns des maîtres d'oeuvre et leur comportement pendant l'oeuvre ainsi que leurs rapports envers le Chapitre de la cathédrale et avec d'autres maîtres de l'époque.

Energy Technology Data Exchange (ETDEWEB)

Casajus, V.

2004-07-01

After expressing his thanks for being invited to the meeting, Victoriano Casajus said that the hoped he would not be invited again because that would mean there had been another zero, even though it didn't happen in Spain. Casajus also congratulated the Spanish nuclear power plants for their excellent operation. Before beginning his presentation, the director claimed that all of us who are involved in the Spanish electric system can be proud of having a system that is possible one of the best in the world, because it has an excellent generation mix, a tremendously balanced transmission grid and a regulatory system that, although it has its faults, is very capable of responding to society's demands. In his presentation, Casajus took stock of the growing demand for energy and power and provided data that show that the Spanish system has experienced a 43% increase in electric energy demand between 1996 and 2003. The problem is with peak demand. It is paradoxical that, in 1998, reaching 34,000 MW was a dream and now going below that figure is almost impossible. Growth of peak demand during those years was 46%. The Spanish fleet was developed in the 70s for three fundamental reasons: phase-out of liquid fuels, massive inroad of coal, and significant expansion of Spanish nuclear power. Starting in the 90s, construction of generating plants practically came to a standstill, although with the excess installed power and more or less new plants (almost all of them were less than 20 years old) it was possible to maintain 48% growth in demand. However, the coverage rate dropped from a value of 1,45 in 1996 to barely 1.10 in2001 and to 1.05 in 2002. in spite of the inclusion of the so-called renewable or special energies. The problem is that not all sources of energy provide the same coverage, and unmanageable energies cannot be considered for managing a system, added Casajus. The general director of Red Electrica noted that Spain has had problems associated with energy consumption and that the European Commission recommended that outside, non-national sources of energy be increased to 10% of total energy. As a result, international interconnections were increased to that level. The question is: is this the solution to the problem and to what extent can a country afford what happened in Italy. Casajus said: Energy-wise, a country should be self-sufficient, because the problem arises when one depends on neighbors for energy. Spain's interconnection capacity is 6% of production and we will try to reach 10%, but we must not forget that it is necessary to have electric power production capacity when there are generalized problems of production.

2017-05-04

Owing to a renewed interest in flat space higher spin gauge theories, in this note we provide further details and clarifications on the results presented in arXiv:1107.5843 and arXiv: 1209.5755, which investigated their locality properties. Focusing, for simplicity, on quartic couplings with one of the external legs having non-zero integer spin (which can be considered as a prototype for Weinberg-type arguments), we review the appearance of 1/◻ non-localities. In particular, we emphasise that it appears to be not possible to eliminate all of the aforementioned non-localities in the general quartic Noether procedure solution with a judicious choice of coupling constants and spectrum. We also discuss the light-cone gauge fixing in d=4, and argue that the non-local obstruction discussed in the covariant language cannot be avoided using light-cone gauge formalism.

A new vacuum for loop quantum gravity

International Nuclear Information System (INIS)

Dittrich, Bianca; Geiller, Marc

2015-01-01

We construct a new vacuum and representation for loop quantum gravity. Because the new vacuum is based on BF theory, it is physical for (2+1)-dimensional gravity, and much closer to the spirit of spin foam quantization in general. To construct this new vacuum and the associated representation of quantum observables, we introduce a modified holonomy–flux algebra that is cylindrically consistent with respect to the notion of refinement by time evolution suggested in Dittrich and Steinhaus (2013 arXiv:1311.7565). This supports the proposal for a construction of the physical vacuum made in Dittrich and Steinhaus (2013 arXiv:1311.7565) and Dittrich (2012 New J. Phys. 14 123004), and for (3+1)-dimensional gravity. We expect that the vacuum introduced here will facilitate the extraction of large scale physics and cosmological predictions from loop quantum gravity. (fast track communication)

On Schwinger mechanism for gluon pair production in the presence of arbitrary time dependent chromo-electric field

2009-11-15

Recently the paper ''Schwinger mechanism for gluon pair production in the presence of arbitrary time dependent chromo-electric field'' by G. C. Nayak was published [Eur. Phys. J. C. 59: 715, 2009; arXiv: 0708.2439]. Its aim is to obtain an exact expression for the probability of non-perturbative gluon pair production per unit time per unit volume and per unit transverse momentum in an arbitrary time-dependent chromo-electric background field. We believe that the obtained expression is open to question. We demonstrate its inconsistency on some well-known examples. We think that this is a consequence of using the so-called ''shift theorem'' [arXiv: hep-th/0609192 ] in deriving the expression for the probability. We make some critical comments on the theorem and its applicability to the problem in question. (orig.)

In a paper on arXiv, Bonitz et al (2012 arXiv:1205.4922v1 [physics.plasm-ph]) (hereafter referred to as BPS) erroneously attributed the qualitative discrepancy between their density functional theory (DFT) simulation results with the analytical discovery of the Shukla-Eliasson (SE) attractive force which brings ions closer to the failure of the linearized quantum hydrodynamic theory. In this paper, we describe the underlying physics of the novel SE attractive force and its validity, as well as discuss some of the key features of the well-established quantum hydrodynamic theory and working mechanisms for DFT simulations, in addition to giving some critical notes on the falsified and misleading conclusions presented by BPS in their dubious paper. Furthermore, we also present a mass-density value for possible 4He metallic plasma lattice formation under the SE force.

Ruppert, Joerg

The energy and momentum lost by a hard parton propagating through hot and dense matter has to be redistributed during the nuclear medium evolution. Apart from heating the medium, there is the possibility that collective modes are excited leading to the emergence of Mach cones or Cherenkov radiation. Recent two-particle correlation measurements by STAR [F. Wang [STAR Collaboration], J. Phys. G 30, S1299 (2004) [arXiv:nucl-ex/0404010]; C. Gagliardi, these proceedings] and PHENIX [S. S. Adler et al. [PHENIX Collaboration], arXiv:nucl-ex/0507004; N. Ajitanand, these proceedings] at RHIC indicate that such phenomena may play an important role in understanding the jet-medium interactions. Possible collective modes are discussed and it is demonstrated that Mach cones as created by colorless or colored sound are a possible explanation of the hardronic two-particle correlation data

Taking a vector supermultiplet apart: Alternative Fayet-Iliopoulos-type terms

Science.gov (United States)

Kuzenko, Sergei M.

2018-06-01

Starting from an Abelian N = 1 vector supermultiplet V coupled to conformal supergravity, we construct from it a nilpotent real scalar Goldstino superfield V of the type proposed in arxiv:arXiv:1702.02423. It contains only two independent component fields, the Goldstino and the auxiliary D-field. The important properties of this Goldstino superfield are: (i) it is gauge invariant; and (ii) it is super-Weyl invariant. As a result, the gauge prepotential can be represented as V = V + V, where V contains only one independent component field, modulo gauge degrees of freedom, which is the gauge one-form. Making use of V allows us to introduce new Fayet-Iliopoulos-type terms, which differ from the one proposed in arxiv:arXiv:1712.08601 and share with the latter the property that gauged R-symmetry is not required.

AMS-02 is a high precision magnetic spectrometer for cosmic rays in the GeV to TeV energy range. Its tracker consists of nine layers of double-sided silicon microstrip sensors. They are used to locate the trajectories of cosmic rays in the 0.14 T field of a cylindrical magnet, thus measuring their rigidity $p/Z$ and charge sign. In addition, they deliver a high resolution measurement of the absolute charge $|Z|$. The detector has been designed to operate in space with a position resolution of about 10 $\\mu$m for each hit and charge identification capabilities up to $Z=26$. In this talk I describe the performance in orbit of this detector component and its impact on the overall performance of the spectrometer.

Baby MIND is a magnetized iron neutrino detector, with novel design features, and is planned to serve as a downstream magnetized muon spectrometer for the WAGASCI experiment on the T2K neutrino beam line in Japan. One of the main goals of this experiment is to reduce systematic uncertainties relevant to CP-violation searches, by measuring the neutrino contamination in the anti-neutrino beam mode of T2K. Baby MIND is currently being constructed at CERN, and is planned to be operational in Japan in October 2017.

arXiv Integrable flows between exact CFTs

CERN Document Server

Georgiou, George

2017-11-14

We explicitly construct families of integrable σ-model actions smoothly inter-polating between exact CFTs. In the ultraviolet the theory is the direct product of two current algebras at levels k$_{1}$ and k$_{2}$. In the infrared and for the case of two deformation matrices the CFT involves a coset CFT, whereas for a single matrix deformation it is given by the ultraviolet direct product theories but at levels k$_{1}$ and k$_{2}$ − k$_{1}$. For isotropic deformations we demonstrate integrability. In this case we also compute the exact beta-function for the deformation parameters using gravitational methods. This is shown to coincide with previous results obtained using perturbation theory and non-perturbative symmetries.

arXiv Neutrino Masses from Outer Space

CERN Document Server

D'Amico, Guido; Kaloper, Nemanja

Neutrinos can gain mass from coupling to an ultralight field in slow roll. When such a field is displaced from its minimum, its vev acts just like the Higgs vev in spontaneous symmetry breaking. Although these masses may eventually vanish, they do it over a very long time. The theory is technically natural, with the ultralight field-dependent part being the right-handed Majorana mass. The mass variation induced by the field correlates with the cosmological evolution. The change of the mass term changes the mixing matrix, and therefore suppresses the fraction of sterile neutrinos at earlier times and increases it at later times. Since the issue of quantum gravity corrections to field theories with large field variations remains open, this framework may give an observational handle on the Weak Gravity Conjecture.

arXiv Laura++ : a Dalitz plot fitter

Back, John; Harrison, Paul; Latham, Thomas; O'Hanlon, Daniel; Qian, Wenbin; del Amo Sanchez, Pablo; Craik, Daniel; Ilic, Jelena; Otalora Goicochea, Juan; Puccio, Eugenia; Silva Coutinho, Rafael; Whitehead, Mark

The Dalitz plot analysis technique has become an increasingly important method in heavy flavour physics. The Laura++ fitter has been developed as a flexible tool that can be used for Dalitz plot analyses in different experimental environments. Explicitly designed for three-body decays of heavy-flavoured mesons to spinless final state particles, it is optimised in order to describe all possible resonant or nonresonant contributions, and to accommodate possible CP violation effects.

Ruling out Critical Higgs Inflation? arXiv

CERN Document Server

Masina, Isabella

We consider critical Higgs inflation, namely Higgs inflation with a rising inflection point at smaller field values than those of the plateau induced by the non-minimal coupling to gravity. It has been proposed that such configuration is compatible with the present CMB observational constraints on inflation, and also with primordial black hole production accounting for the totality or a fraction of the observed dark matter. We study the model taking into account the NNLO corrections to the Higgs effective potential: such corrections are extremely important to reduce the theoretical error associated to the calculation. We find that, in the 3 sigma window for the relevant low energy parameters, which are the strong coupling and the Higgs mass (the top mass follows by requiring an inflection point), the potential at the inflection point is so large (and so is the Hubble constant during inflation) that the present bound on the tensor-to-scalar ratio is violated. The model is viable only allowing the strong coupli...

It seems hardly necessary to repeat to an audience of this kind the importance of the process known as photosynthesis in the interaction and the interdependence of organisms and in the very existence of life as we know it. This process by which green plants are able to capture electromagnetic energy in the form of sunlight and transform it into stored chemical energy in the form of a wide variety of reduced (relative to carbon dioxide) carbon compounds provides the only major source of energy for the maintenance and propagation of all life.

arXiv Collider constraints on light pseudoscalars

Haisch, Ulrich; Malinauskas, Augustinas; Spira, Michael

2018-03-28

We investigate the bounds on light pseudoscalars that arise from a variety of collider searches. Special attention is thereby devoted to the mass regions [3, 5] GeV and [9, 11] GeV, in which a meaningful theoretical description has to include estimates of non-perturbative effects such as the mixing of the pseudoscalar with QCD bound states. A compendium of formulas that allows to deal with the relevant corrections is provided. It should prove useful for the interpretation of future LHC searches for light CP-odd spin-0 states.

arXiv Agravity up to infinite energy

Salvio, Alberto

2018-02-10

The self-interactions of the conformal mode of the graviton are controlled, in dimensionless gravity theories (agravity), by a coupling $f_0$ that is not asymptotically free. We show that, nevertheless, agravity can be a complete theory valid up to infinite energy. When $f_0$ grows to large values, the conformal mode of the graviton decouples from the rest of the theory and does not hit any Landau pole provided that scalars are asymptotically conformally coupled and all other couplings approach fixed points. Then agravity can flow to conformal gravity at infinite energy. We identify scenarios where the Higgs mass does not receive unnaturally large physical corrections. We also show a useful equivalence between agravity and conformal gravity plus two extra conformally coupled scalars, and we give a simpler form for the renormalization group equations of dimensionless couplings as well as of massive parameters in the presence of the most general matter sector.

Asymptotically Safe Standard Model Extensions arXiv

Pelaggi, Giulio Maria; Salvio, Alberto; Sannino, Francesco; Smirnov, Juri; Strumia, Alessandro

We consider theories with a large number NF of charged fermions and compute the renormalisation group equations for the gauge, Yukawa and quartic couplings resummed at leading order in NF. We construct extensions of the Standard Model where SU(2) and/or SU(3) are asymptotically safe. When the same procedure is applied to the Abelian U(1) factor, we find that the Higgs quartic can not be made asymptotically safe and stay perturbative at the same time.

arXiv Quantum coherence of cosmological perturbations

CERN Document Server

Giovannini, Massimo

2017-10-26

In this paper, the degrees of quantum coherence of cosmological perturbations of different spins are computed in the large-scale limit and compared with the standard results holding for a single mode of the electromagnetic field in an optical cavity. The degree of second-order coherence of curvature inhomogeneities (and, more generally, of the scalar modes of the geometry) reproduces faithfully the optical limit. For the vector and tensor fluctuations, the numerical values of the normalized degrees of second-order coherence in the zero time-delay limit are always larger than unity (which is the Poisson benchmark value) but differ from the corresponding expressions obtainable in the framework of the single-mode approximation. General lessons are drawn on the quantum coherence of large-scale cosmological fluctuations.

These notes represent a summary of three lectures on flavour and CP violation, given at the CERNs European School of High Energy Physics in 2014. They cover flavour physics within the standard model, phenomenology of CP violation in meson mixing and decays, as well as constraints of flavour observableson physics beyond the standard model. In preparing the lectures (and consequently this summary) I drew heavily from several existing excellent and exhaustive sets of lecture notes and reviews on flavour physics and CP violation [1]. The reader is encouraged to consult those as well as the original literature for a more detailed study.

When the same procedure is applied to the Abelian U(1) factor, we find that the Higgs quartic can not be made asymptotically safe and stay perturbative at the same time.

Full Text Available Introducción: El factor tiempo es determinante en la eficacia de la diálisis, recomendando las European Best Practices Guides of Dialysys Adequaccy una duración semanal no inferior a 720 minutos. Los modernos monitores de diálisis interrumpen el procedimiento por auto chequeos que incrementan la seguridad. Esos minutos de diferencia no han sido tenidos en cuenta en otros resultados obtenidos, algún autor ya hace referencia a la necesidad de contemplarlos. Los objetivos del presente estudio fueron determinar la diferencia real entre el tiempo programado y el tiempo efectivo de diálisis, y una vez comprobado incrementar la duración de la sesión para hacer que el tiempo efectivo sea realmente el deseado en cada paciente, y nunca inferior a 240 minutos por sesión. Finalmente comprobamos si existen diferencias en la eficacia dialítica, midiendo el Kt y el volumen total de reinfusión. Pacientes y métodos: Diseñamos un estudio prospectivo sobre población prevalente en hemodiafiltración on-line. Reclutamos 152 pacientes en hemodiafiltración on-line. Durante 6 sesiones consecutivas (912 sesiones la diálisis se efectuó con un tiempo programado ≥ 240 minutos. En un segundo periodo 6 sesiones consecutivas (912 sesiones, la sesión de diálisis se alargó hasta un tiempo efectivo igual al previo programado. La variable principal en estudio fue el tiempo, siendo variables secundarias el flujo sanguíneo, Kt, y volumen total de reinfusión.
