Spatial Air Index Based on Largest Empty Rectangles for Non-Flat Wireless Broadcast in Pervasive Computing
Authors: Shen Jun-Hong , Lu Ching-Ta , Chen Mu-Yen , Mai Chien-Tang
Published: November 2016

In pervasive computing, location-based services (LBSs) are valuable for mobile clients based on their current locations. LBSs use spatial window queries to enable useful applications for mobile clients. Based on skewed access patterns of mobile clients, non-flat wireless broadcast has been shown to efficiently disseminate spatial objects to mobile clients. In this paper, we consider a scenario in which spatial objects are broadcast to mobile clients over a wireless channel in a non-flat broadcast manner to process window queries. For such a scenario, we propose an efficient spatial air index method to handle window query access in non-flat wireless broadcast environments. The concept of largest empty rectangles is used to avoid unnecessary examination of the broadcast content, thus reducing the processing time for window queries. Simulation results show that the proposed spatial air index method outperforms the existing methods under various settings.

2.5D map is a convenient and efficient approach to exploiting a massive three-dimensional (3D) city model in web GIS. With the rapid development of oblique airborne photogrammetry and photo-based 3D reconstruction, 3D city models are becoming more and more accessible. 3D Geographic Information System (GIS) can support the interactive visualization of massive 3D city models on various platforms and devices. However, the value and accessibility of existing 3D city models can be augmented by integrating them into web-based two-dimensional (2D) GIS applications. In this paper, we present a step-by-step workflow for generating orthorectified oblique images (2.5D maps) from massive 3D city models. The proposed framework can produce 2.5D maps from an arbitrary perspective, defined by the elevation angle and azimuth angle of a virtual orthographic camera. We demonstrate how 2.5D maps can benefit web-based visualization and exploitation of massive 3D city models. We conclude that a 2.5D map is a compact data representation optimized for web data streaming of 3D city models and that geometric analysis of buildings can be effectively conducted on 2.5D maps.

Single nucleotide polymorphisms (SNPs) are widely used in functional genomics and genetics research work. The high-quality sequence of rice genome has provided a genome-wide SNP and proteome resource. However, the impact of SNPs on protein phosphorylation status in rice is not fully understood. In this paper, we firstly updated rice SNP resource based on the new rice genome Ver. 7.0, then systematically analyzed the potential impact of Non-synonymous SNPs (nsSNPs) on the protein phosphorylation status. There were 3,897,312 SNPs in Ver. 7.0 rice genome, among which 9.9% was nsSNPs. Whilst, a total 2,508,261 phosphorylated sites were predicted in rice proteome. Interestingly, we observed that 150,197 (39.1%) nsSNPs could influence protein phosphorylation status, among which 52.2% might induce changes of protein kinase (PK) types for adjacent phosphorylation sites. We constructed a database, SNP_rice, to deposit the updated rice SNP resource and phosSNPs information. It was freely available to academic researchers at http://bioinformatics.fafu.edu.cn. As a case study, we detected five nsSNPs that potentially influenced heterotrimeric G proteins phosphorylation status in rice, indicating that genetic polymorphisms showed impact on the signal transduction by influencing the phosphorylation status of heterotrimeric G proteins. The results in this work could be a useful resource for future experimental identification and provide interesting information for better rice breeding.

Published: November 2016

Protein phosphatase 2 regulatory subunit B, alpha (PPP2R3A), a regulatory subunit of protein phosphatase 2A (PP2A), is a major serine/threonine phosphatase that regulates crucial function in development and growth. Previous research has implied that PPP2R3A was involved in heart failure, and PR130, the largest transcription of PPP2R3A, functioning in the calcium release of sarcoplasmic reticulum (SR), plays an important role in the excitation-contraction (EC) coupling. To obtain a better understanding of PR130 functions in myocardium and cardiac development, two pr130-deletion zebrafish lines were generated using clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated proteins (Cas) system. Pr130-knockout zebrafish exhibited cardiac looping defects and decreased cardiac function (decreased fractional area and fractional shortening). Hematoxylin and eosin (H&E) staining demonstrated reduced cardiomyocytes. Subsequent transmission electron microscopy revealed that the bright and dark bands were narrowed and blurred, the Z- and M-lines were fogged, and the gaps between longitudinal myocardial fibers were increased. Additionally, increased apoptosis was observed in cardiomyocyte in pr130-knockout zebrafish compared to wild-type (WT). Taken together, our results suggest that pr130 is required for normal myocardium formation and efficient cardiac contractile function.

Published: November 2016

We demonstrate an erbium-doped fiber laser passively Q-switched by a black-phosphorus polyimide film. The multi-layer black-phosphorus (BP) nanosheets were prepared via a liquid exfoliation approach exploiting N-methylpyrrolidone as the dispersion liquid. By mixing the BP nanosheets with polyimide (PI), a piece of BP–PI film was obtained after evaporating the mixture in a petri dish. The BP–PI saturable absorber had a modulation depth of 0.47% and was inserted into an erbium-doped fiber laser to realize passive Q-switched operations. The repetition rate of the Q-switched laser increased from 5.73 kHz to 31.07 kHz when the laser pump was enhanced from 31.78 mW to 231.46 mW. Our results show that PI is an excellent host material to protect BP from oxidation, and the BP–PI film can act as a promising nonlinear optical device for laser applications.
Novel Superdielectric Materials: Aqueous Salt Solution Saturated Fabric
Authors: Phillips Jonathan
Published: November 2016

The dielectric constants of nylon fabrics saturated with aqueous NaCl solutions, Fabric-Superdielectric Materials (F-SDM), were measured to be >105 even at the shortest discharge times (>0.001 s) for which reliable data could be obtained using the constant current method, thus demonstrating the existence of a third class of SDM. Hence, the present results support the general theoretical SDM hypothesis, which is also supported by earlier experimental work with powder and anodized foil matrices: Any material composed of liquid containing dissolved, mobile ions, confined in an electrically insulating matrix, will have a very high dielectric constant. Five capacitors, each composed of a different number of layers of salt solution saturated nylon fabric, were studied, using a galvanostat operated in constant current mode. Capacitance, dielectric constant, energy density and power density as a function of discharge time, for discharge times from ~100 s to nearly 0.001 s were recorded. The roll-off rate of the first three parameters was found to be nearly identical for all five capacitors tested. The power density increased in all cases with decreasing discharge time, but again the observed frequency response was nearly identical for all five capacitors. Operational limitations found for F-SDM are the same as those for other aqueous solution SDM, particularly a low maximum operating voltage (~2.3 V), and dielectric “constants” that are a function of voltage, decreasing for voltages higher than ~0.8 V. Extrapolations of the present data set suggest F-SDM could be the key to inexpensive, high energy density (>75 J/cm3) capacitors.
Glutathione-Conjugates of Deoxynivalenol in Naturally Contaminated Grain Are Primarily Linked via the Epoxide Group

Published: November 2016

A glutathione (GSH) adduct of the mycotoxin 4-deoxynivalenol (DON), together with a range of related conjugates, has recently been tentatively identified by LC-MS of DON-treated wheat spikelets. In this study, we prepared samples of DON conjugated at the 10- and 13-positions with GSH, Cys, CysGly, γ-GluCys and N-acetylcysteine (NAC). The mixtures of conjugates were used as standards for LC-HRMS analysis of one of the DON-treated wheat spikelet samples, as well as 19 Norwegian grain samples of spring wheat and 16 grain samples of oats that were naturally-contaminated with DON at concentrations higher than 1 mg/kg. The artificially-contaminated wheat spikelets contained conjugates of GSH, CysGly and Cys coupled at the olefinic 10-position of DON, whereas the naturally-contaminated harvest-ripe grain samples contained GSH, CysGly, Cys, and NAC coupled mainly at the 13-position on the epoxy group. The identities of the conjugates were confirmed by LC-HRMS comparison with authentic standards, oxidation to the sulfoxides with hydrogen peroxide, and examination of product-ion spectra from LC-HRMS/MS analysis. No γ-GluCys adducts of DON were detected in any of the samples. The presence of 15-O-acetyl-DON was demonstrated for the first time in Norwegian grain. The results indicate that a small but significant proportion of DON is metabolized via the GSH-conjugation pathway in plants. To our knowledge, this is the first report of in vivo conjugation of trichothecenes via their epoxy group, which has generally been viewed as unreactive. Because conjugation at the 13-position of DON and other trichothecenes has been shown to be irreversible, this type of conjugate may prove useful as a biomarker of exposure to DON and other 12,13-epoxytrichothecenes.

We present results from a comprehensive submillimeter spectral survey toward the source Orion South, based on data obtained with the Heterodyne Instrument for the Far-Infrared instrument on board the Herschel Space Observatory, covering the frequency range of 480 to 1900 GHz. We detect 685 spectral lines with signal-to-noise ratios (S/Ns) > 3σ, originating from 52 different molecular and atomic species. We model each of the detected species assuming conditions of Local Thermodynamic Equilibrium. This analysis provides an estimate of the physical conditions of Orion South (column density, temperature, source size, and V
LSR). We find evidence for three different cloud components: a cool (T
ex ∼ 20–40 K), spatially extended (>60″), and quiescent (ΔV
FWHM ∼ 4 km s−1) component; a warmer (T
ex ∼ 80–100 K), less spatially extended (∼30″), and dynamic (ΔV
FWHM ∼ 8 km s−1) component, which is likely affected by embedded outflows; and a kinematically distinct region (T
ex > 100 K; V
LSR ∼ 8 km s−1), dominated by emission from species that trace ultraviolet irradiation, likely at the surface of the cloud. We find little evidence for the existence of a chemically distinct “hot-core” component, likely due to the small filling factor of the hot core or hot cores within the Herschel beam. We find that the chemical composition of the gas in the cooler, quiescent component of Orion South more closely resembles that of the quiescent ridge in Orion-KL. The gas in the warmer, dynamic component, however, more closely resembles that of the Compact Ridge and Plateau regions of Orion-KL, suggesting that higher temperatures and shocks also have an influence on the overall chemistry of Orion South.
TYPE Ia SUPERNOVA EXPLOSIONS FROM HYBRID CARBON–OXYGEN–NEON WHITE DWARF PROGENITORS

Published: November 2016

Motivated by recent results in stellar evolution that predict the existence of hybrid white dwarf (WD) stars with a C–O core inside an O–Ne shell, we simulate thermonuclear (Type Ia) supernovae from these hybrid progenitors. We use the FLASH code to perform multidimensional simulations in the deflagration-to-detonation transition (DDT) explosion paradigm. Our hybrid progenitor models were produced with the MESA stellar evolution code and include the effects of the Urca process, and we map the progenitor model to the FLASH grid. We performed a suite of DDT simulations over a range of ignition conditions consistent with the progenitor’s thermal and convective structure assuming multiple ignition points. To compare the results from these hybrid WD stars to previous results from C–O WDs, we construct a set of C–O WD models with similar properties and similarly simulate a suite of explosions. We find that despite significant variability within each suite, trends distinguishing the explosions are apparent in their

yields and the kinetic properties of the ejecta. We compare our results with other recent work that studies explosions from these hybrid progenitors.
AN ORDERED MAGNETIC FIELD IN THE PROTOPLANETARY DISK OF AB Aur REVEALED BY MID-INFRARED POLARIMETRY

Published: November 2016

Magnetic fields (B-fields) play a key role in the formation and evolution of protoplanetary disks, but their properties are poorly understood due to the lack of observational constraints. Using CanariCam at the 10.4 m Gran Telescopio Canarias, we have mapped out the mid-infrared polarization of the protoplanetary disk around the Herbig Ae star AB Aur. We detect ∼0.44% polarization at 10.3 μm from AB Aur's inner disk (r < 80 au), rising to ∼1.4% at larger radii. Our simulations imply that the mid-infrared polarization of the inner disk arises from dichroic emission of elongated particles aligned in a disk B-field. The field is well ordered on a spatial scale, commensurate with our resolution (∼50 au), and we infer a poloidal shape tilted from the rotational axis of the disk. The disk of AB Aur is optically thick at 10.3 μm, so polarimetry at this wavelength is probing the B-field near the disk surface. Our observations therefore confirm that this layer, favored by some theoretical studies for developing magneto-rotational instability and its resultant viscosity, is indeed very likely to be magnetized. At radii beyond ∼80 au, the mid-infrared polarization results primarily from scattering by dust grains with sizes up to ∼1 μm, a size indicating both grain growth and, probably, turbulent lofting of the particles from the disk mid-plane.
ILLUMINATING BLACK HOLE BINARY FORMATION CHANNELS WITH SPINS IN ADVANCED LIGO

Published: November 2016

The recent detections of the binary black hole mergers GW150914 and GW151226 have inaugurated the field of gravitational-wave astronomy. For the two main formation channels that have been proposed for these sources, isolated binary evolution in galactic fields and dynamical formation in dense star clusters, the predicted masses and merger rates overlap significantly, complicating any astrophysical claims that rely on measured masses alone. Here, we examine the distribution of spin–orbit misalignments expected for binaries from the field and from dense star clusters. Under standard assumptions for black hole natal kicks, we find that black hole binaries similar to GW150914 could be formed with significant spin–orbit misalignment only through dynamical processes. In particular, these heavy-black hole binaries can only form with a significant spin–orbit anti-alignment in the dynamical channel. Our results suggest that future detections of merging black hole binaries with measurable spins will allow us to identify the main formation channel for these systems.
CHEMICAL DIVERSITY IN THE ULTRA-FAINT DWARF GALAXY TUCANA II*

Published: November 2016

We present the first detailed chemical abundance study of the ultra-faint dwarf galaxy Tucana II, based on high-resolution Magellan/MIKE spectra of four red giant stars. The metallicities of these stars range from [Fe/H] = −3.2 to −2.6, and all stars are low in neutron-capture abundances ([Sr/Fe] and [Ba/Fe] < −1). However, a number of anomalous chemical signatures are present. One star is relatively metal-rich ([Fe/H] = −2.6) and shows [Na, α, Sc/Fe] < 0, suggesting an extended star formation history with contributions from AGB stars and SNe Ia. Two stars with [Fe/H] < −3 are mildly carbon-enhanced ([C/Fe] ∼ 0.7) and may be consistent with enrichment by faint supernovae, if such supernovae can produce neutron-capture elements. A fourth star with [Fe/H] = −3 is carbon-normal, and exhibits distinct light element abundance ratios from the carbon-enhanced stars. This carbon-normal star implies that at least two distinct nucleosynthesis sources, both possibly associated with Population III stars, contributed to the early chemical enrichment of this galaxy. Despite its very low luminosity, Tucana II shows a diversity of chemical signatures that preclude it from being a simple “one-shot” first galaxy yet still provide a window into star and galaxy formation in the early universe.
ESTIMATING THE GeV EMISSION OF MILLISECOND PULSARS IN DWARF SPHEROIDAL GALAXIES
Authors: Winter Miles , Zaharijas Gabrijela , Bechtol Keith , Vandenbroucke Justin
Published: November 2016

We estimate the conventional astrophysical emission from dwarf spheroidal satellite galaxies (dSphs) of the Milky Way (MW), focusing on millisecond pulsars (MSPs), and evaluate the potential for confusion with dark matter (DM) annihilation signatures at GeV energies. In low-density stellar environments, such as dSphs, the abundance of MSPs is expected to be proportional to stellar mass. Accordingly, we construct the γ-ray luminosity function (LF) of MSPs in the MW disk, where >90 individual MSPs have been detected with the Fermi Large Area Telescope (LAT), and scale this LF to the stellar masses of 30 dSphs to estimate the cumulative emission from their MSP populations. We predict that MSPs within the highest stellar mass dSphs, Fornax and Sculptor, produce a γ-ray flux >500 MeV of ∼10−11 ph cm−2 s−1, which is a factor ∼10 below the current LAT sensitivity at high Galactic latitudes. The MSP emission in ultra-faint dSphs, including targets with the largest J-factors, is typically several orders of magnitude lower, suggesting that these targets will remain clean targets for indirect DM searches in the foreseeable future. For a DM particle of mass 25 GeV annihilating to b quarks at the thermal relic cross section (consistent with DM interpretations of the Galactic Center excess), we find that the expected γ-ray emission due to DM exceeds that of MSPs in all of the target dSphs. Using the same MW MSP population model, we also estimate the Galactic foreground MSP coincidence probability along the same sightlines to the dSphs.
De l’inconstance du style de négociation chez les jeunes commerciaux
Authors: Brassier Pascal
Published: November 2016

Comment les jeunes négociateurs perçoivent-ils leur propre style en négociation ? Entre une pression sociale qui tend à les pousser à devenir collaboratifs, les attentes et la culture de leur entreprise, leur crainte face à la confrontation et aux nécessaires résultats, quelle place leur style personnel peut-il trouver ? Cet article vise à porter un regard critique sur plusieurs points soutenant une telle injonction paradoxale : des facteurs d’influence parfois contradictoires, des attitudes a priori peu homogènes, une capacité discutable à s’adapter et adopter un style plus efficace. Une étude empirique menée avec plus de 180 jeunes négociateurs montre que la détermination d’un style de négociation particulier n’est pas aisée. L’existence d’une pluralité « molle » des styles incite plutôt à suggérer plus d’accompagnement managérial pour élargir la palette des capacités des jeunes négociateurs.
Deux siècles de politiques publiques des drogues
Authors: Bisiou Yann
Published: November 2016

Dès l’origine, le tabac, l’alcool, l’opium ou même le cannabis ont été considérés comme des produits dangereux qui justifiaient soit une taxation élevée, soit un contrôle de l’État, soit même une prohibition. Ce n’est qu’avec le mouvement international de lutte contre l’opium puis les stupéfiants au début du XX e  siècle que cette approche « globale » disparaît au profit d’une focalisation sur les produits plutôt que sur les comportements. Les politiques publiques vont alors diverger autour de deux grands objectifs contradictoires : favoriser l’offre de drogue, pour des raisons économiques ou fiscales ou, au contraire, lutter contre l’offre de drogue pour des raisons d’abord morales, ensuite sanitaires. L’auteur balaie deux siècles de législation des drogues, jusqu’à la Loi Santé promulguée en 2016.
Rôle de l’intelligence émotionnelle dans les comportements agressifs dans le domaine sportif
Authors: Dosseville Fabrice , Laborde Sylvain , Edoh Koffi Pierrot , Garncarzyk Catherine
Published: November 2016

L’intelligence émotionnelle (IE), définie comme un ensemble de compétences concernant l’identification, la compréhension, l’expression, la régulation et l’utilisation de ses émotions et de celles des autres, a souvent été considérée comme une dimension individuelle déterminante dans la vie sociale, affective et professionnelle. Dans le domaine des pratiques sportives, les travaux se sont multipliés depuis quelques années en s’intéressant à la performance, au ressenti émotionnel, aux réponses et aux comportements face aux événements perçus comme stressants. Mais il est surprenant d’observer que les travaux évoquant les liens entre ces compétences émotionnelles et la violence dans le sport sont rares, alors que les comportements agressifs et violents ne cessent d’augmenter sur et autour des terrains. L’objectif de cet article est ainsi de montrer les liens entre l’IE et les comportements transgressifs en sport et de proposer des perspectives de recherche dans ce domaine encore peu exploré en psychologie du sport et de l’activité physique.
Cochères parisiennes, le risque en spectacle
Authors: Rennes Juliette
Published: November 2016

À Paris, le 21 février 1907, plusieurs dizaines de photographes et de journalistes se bousculent pour être les premiers clients des deux premières femmes cochers de Paris. Dès 1906, les cochères, alors en apprentissage, suscitaient déjà maints reportages et devenaient des personnages de fiction dans les spectacles de revue, les dessins satiriques, les premiers films des sociétés Pathé et Gaumont. Cet article confronte cette prolifération d’archives visuelles et médiatiques sur « la femme cocher » à des archives d’état civil, du recensement, de la statistique municipale et de la préfecture de police, pour enquêter sur le processus par lequel ces femmes, souvent issues des classes laborieuses rurales, accédèrent à une corporation perçue comme masculine par sa composition statistique et son identité sociale. Le risque et la prouesse mis en scène dans ce spectacle des femmes cochers, essentiellement destiné à divertir un public bourgeois, sont alors confrontés à ce que risquaient effectivement ces travailleuses particulièrement visibles et exposées dans l’espace parisien, en tant que femmes minoritaires dans un métier masculin.
Devenir artiste de cirque : l’apprentissage du risque
Authors: Legendre Florence
Published: November 2016

Le risque occupe une place centrale dans les activités de cirque, notamment parce qu’elles engagent l’intégrité corporelle des artistes. Les activités physiques dites à risque s’appuient sur des valeurs et des normes éminemment masculines or le cirque est tout à la fois un espace relativement mixte et nettement genré, il apparait alors pertinent de s’interroger sur les expériences d’apprentissage des rapports au risque, comme principes organisateurs de la socialisation professionnelle des accédants et des accédantes. Comment devient-on artiste de cirque au regard de ces risques professionnels ? Les étudiant-e-s engagent tout au long de leur cursus de formation un travail biographique d’ajustement autour de trois objets de socialisation qui émergent de leurs narrations : (re)définir les risques professionnels, apprendre à gérer les risques corporels et construire une posture d’artiste de cirque.
Le plafond de verre chez les enseignants-chercheurs en sociologie et démographie
Authors: Chenu Alain , Martin Olivier
Published: November 2016

La féminisation de l’enseignement supérieur français va croissante : la discipline « sociologie, démographie » illustre bien cette évolution puisqu’en 2012 44 % des enseignants-chercheurs en « sociologie, démographie » sont des femmes alors que ce taux ne s’élevait qu’à 24 % en 1984. Pourtant, cette féminisation croissante cache la persistance d’un plafond de verre. Cet article en montre l’existence et cherche à l’expliquer. À cet effet, la carrière des enseignants-chercheurs est analysée étape par étape (qualification, accès au corps des maîtres de conférences, éventuelle qualification comme professeur, accès éventuel à ce corps) à l’aide de données individuelles concernant la période 1984-2013. Si l’accès au corps des maîtres de conférences ne semble pas (ou plus) être entaché d’une inégalité défavorable aux femmes, ce n’est pas le cas de l’accès au corps des professeurs : le plafond de verre se situe sur le chemin qui mène les maîtres de conférences au statut de professeur.
La experiencia moral: una ética sin verdades absolutas
Authors: Barroso Fernández Óscar
Published: November 2016

En este trabajo se pretende reconstruir la propuesta zubiriana de un saber de tipo moral. Este objetivo exige mirar los textos de antropología moral escritos por Zubiri en los años cincuenta desde su obra más acabada: Inteligencia sentiente. Si efectivamente se puede hablar de un saber moral, habrá que descubrir cuál es su sistema de referencia, constituido por determinados contenidos dados en impresión primordial de realidad y mediados por el logos, y su forma de conocimiento, con sus esbozos, experiencias y verdades. A partir de aquí, el autor muestra que no es posible, desde la filosofía de Zubiri, proponer una fundamentación de la moral en sentido universal y absoluto. En todo caso, la posibilidad de un ámbito universal de moralidad no puede ser entendida como algo dado a priori, sino más bien como un ideal regulativo de la experiencia moral, algo a lo que la razón apunta pero nunca llega.
Fundación: última radicalización noérgica de la inteligencia sentiente
Authors: Danel Janet Fernando
Published: November 2016

Tras la revisión del problema del fundamento en la fenomenología de Heidegger que el joven Zubiri critica tempranamente en su filosofía, apunta a su radicalización con el análisis de la religación, en los años treinta del siglo pasado. El tema del fundamento continúa en la obra madura de Zubiri, pero no alcanza estatuto noérgico sugerido desde la perspectiva de “Inteligencia sentiente” del final de su vida. La fundación permanece impensada en el tema del fundamento.
Zubiri urbanizado: la filosofía de la experiencia de I. Ellacuría
Authors: Nicolás Juan Antonio
Published: November 2016

Se interpreta la filosofía de Ellacuría como una filosofía de la experiencia en línea con el giro hacia la facticidad propuesto por Heidegger y asumido por Zubiri. Ellacuría parte de la noción de experiencia de Zubiri como impresión de realidad, pero la transforma a partir del rasgo esencial de la asimetría radical con la que los individuos y los colectivos padecen esa presión de la realidad. Esa diferencia originaria es el motor moral de la crítica filosófica y su superación constituye la meta de la acción. Este camino sólo se puede recorrer desde “el lugar que da verdad”, que es la perspectiva de la periferia (marginados, pobres, excluidos, oprimidos, etc.). La propuesta esencial de Ellacuría es poner en el centro de los intereses y de la acción filosófica precisamente a quienes están en los márgenes. Con ello propone una transformación de la metafísica, desde la inversión de la relación centro-periferia. La superación de la asimetría originaria sólo se puede lograr priorizando lo periférico, es decir, poniendo en el centro de atención realmente los intereses y necesidades de quienes la historia y la realidad han relegado a los márgenes.
Sobre el realismo matemático de Zubiri y su interpretación de los teoremas de Gödel y Cohen
Authors: Orellana Estay Oscar , Durán Allimant Ronald
Published: November 2016

En este artículo se analiza el apéndice «La realidad de lo matemático» del libro Inteligencia y Logos, del filósofo español Xavier Zubiri, con el objetivo de clarificar su concepción de los objetos matemáticos como reales por construcción, y a partir de esto su interpretación de los teoremas de Gödel y Cohen, que según Zubiri dejarían en evidencia que la realidad de los objetos matemáticos es anterior a su verdad. Para ello se expone primero, la concepción de Zubiri de los objetos matemáticos; luego se distingue su posición de la de los formalistas e intuicionistas; por último, se analiza la interpretación zubiriana de los teoremas de Cohen y Gödel.
Xavier Zubiri e il problema della verità ‘attuale’
Authors: Ponzio Paolo
Published: November 2016

El presente artículo quiere indagar el problema de la verdad en el pensamiento de Xavier Zubiri, desde sus inicios. Por esta razón, incluso si el objetivo es explorar el concepto de verdad en su última declinación, es decir, dentro de la trilogía de la inteligencia sentiente (1980-1983), no se puede ignorar los ensayos anteriores del filósofo, para evaluar plenamente la originalidad de su pensamiento con respecto a la filosofía del siglo XX.
La bioética desde la filosofía de Zubiri
Authors: Pose Varela Carlos Alberto
Published: November 2016

La historia de la ética muestra que la ética es un saber que se ha ido elaborando progresivamente. Su construcción ha dependido de muchos factores. A partir de Kant la ética se hace universal y categorial, pero hasta entonces nunca lo fue. Anteriormente, al menos con Sócrates y Aristóteles, la ética se basaba en la deliberación como método de investigación de lo bueno; y lo bueno se decía de muchas maneras. En este artículo presentamos una explicación de esta variedad de éticas desde la filosofía de Zubiri. El enfoque que Zubiri da de la vida moral en los años 50, es preciso revisarlo en los años 80 desde la inteligencia sentiente. En los años 50 Zubiri hablaba de la idea de ser humano como factor fundamental en la construcción de la ética. Pero existe otro factor determinante: la intelección y la valoración como modo de construcción de la ética o bioética.
Comunicación en la investigación y su relación con la satisfacción laboral del personal académico investigador e infraestructuras universitarias
Authors: Benito del Valle Lamberto Luis , Guenaga Garay Galder , Renteria-Uriarte Xabier , Luengo-Valderrey María Jesús
Published: November 2016

La comunicación de resultados de investigación resulta preeminente como criterio de calidad e indicador de posicionamiento en rankings mundiales de universidades. Asimismo, se asume que el rendimiento laboral se ve influenciado por el grado de satisfacción de los miembros de la organización con su ambiente laboral y su actividad. La aplicación del modelo estadístico de ecuaciones estructurales a una encuesta sobre satisfacción, motivación e implicación laboral realizada al personal académico investigador de la UPV/EHU concluye que dicha comunicación es potenciada y explicada (en orden descendente) por la posibilidad de: trabajar en ambientes personales no universitarios bien equipados; desarrollar habilidades y plantearse nuevos retos, formarse y proveerse de instrumentos materiales e inmateriales; incentivos, reconocimiento y agilidad burocrática; percepción personal del rendimiento productivo derivado de la satisfacción laboral; satisfacción personal en tareas de comunicación en congresos y otros escenarios; y satisfacción en tareas de preparación y redacción de material de investigación.
Serpúlidos (Annelida, Serpulidae) colectados en la Campaña Oceanográfica “Fauna II” y catálogo actualizado de especies íbero-baleares de la familia Serpulidae

Upper Quadrant Field Tests and Isokinetic Upper Limb Strength in Overhead Athletes
Authors: Borms Dorien , Maenhout Annelies , Cools Ann M.
Published: November 2016

Context: Isokinetic testing is used to determine possible deficits in upper extremity strength in overhead athletes. Given that isokinetic testing is restricted to a laboratory setting, field tests, such as the Seated Medicine Ball Throw (SMBT) and Upper Quarter Y-Balance Test (YBT-UQ), were developed to assess upper body performance. The relationships between these field tests and isokinetic strength have not been examined.

Objective: To investigate the relationship between isokinetic strength testing for shoulder external and internal rotation and elbow flexion and extension and SMBT distance and YBT-UQ performance in overhead athletes.

Design: Cross-sectional study.

Setting: Institutional laboratory.

Patients or Other Participants: A total of 29 healthy overhead athletes (14 men, 15 women; age = 21.6 ± 2.5 years, height = 177.7 ± 9.7 cm, mass = 70.3 ± 11.5 kg).

Intervention(s): A Biodex dynamometer was used to measure the isokinetic strength of the shoulder and elbow muscles. Upper extremity performance was assessed using the SMBT and YBT-UQ.

Main Outcome Measure(s): We used Pearson correlation coefficients and coefficients of determination to analyze the relationship between SMBT and YBT-UQ performance and the isokinetic strength variables.

Results: We observed moderate to strong correlations between the SMBT and isokinetic shoulder and elbow strength (r range = 0.595−0.855) but no correlations between the YBT-UQ and isokinetic strength variables. The shared variance between these strength variables and the SMBT ranged from 35.4% to 64.5% for shoulder strength and 58.5% to 73.1% for elbow strength.

Conclusions: These findings suggested that the SMBT is a reliable, low-cost, and easy- and quick-to-administer alternative to isokinetic testing for evaluating upper extremity strength in a clinical setting. Performance on the YBT-UQ did not seem to be related to upper limb strength and, therefore, cannot be used for this purpose. Using the YBT-UQ for other purposes may have value.
Квантовые возрождения нерабиевского типа в модели Джейнса-Каммингса

Изучаются полные возрождения (т. е. повторные появления в ходе унитарной эволюции) квантовых состояний в модели Джейнса-Каммингса в рамках приближения вращающейся волны. Доказано, что в случае нулевой расстройки в подпространствах, порожденных двумя смежными парами уровней энергии, полные возрождения не имеют места ни при каких значениях параметров. В случае ненулевой расстройки, напротив, множество параметров, допускающих полное возрождение, всюду плотно в множестве всех параметров. Природа данных возрождений отличается от рабиевских осцилляций для одной пары уровней энергии. В более сложных подпространствах проблема существования полного возрождения сводится к частным случаям десятой проблемы Гильберта для рациональных решений систем нелинейных алгебраических уравнений, которая в общем случае не имеет алгоритмического решения. Нерабиевские возрождения становятся частичными в случае отказа от приближения вращающейся волны.

Рассмотрена задача поиска собственных векторов коммутирующего семейства квантовых миноров матрицы монодромии $SL(n,\mathbb C)$-инвариантной неоднородной спиновой цепочки. Генераторы алгебры и элементы $L$-оператора в каждом узле цепочки реализованы как линейные дифференциальные операторы на пространстве функций $n(n-1)/2$ переменных; представление алгебры $sl_n(\mathbb C)$ в каждом узле в общем случае является бесконечномерным и принадлежит к основной унитарной серии. Задача решена при помощи рекуррентной процедуры по рангу алгебры $n$. Получены явные выражения для собственных значений и собственных векторов коммутирующего семейства. Подробно разобраны частные случаи $n=2$ и $n=3$, а также предельный случай цепочки, состоящей из одного узла.
О модулярных преобразованиях в теории Лиувилля
Authors: Nemkov Nikita Andreevich
Published: November 2016

Модулярное ядро невырожденных конформных блоков в теории Лиувилля изучается как решение разностных уравнений, происходящих из тождества пентагона. Предлагается подход к решению этих уравнений, основанный на непертурбативном разложении, которое позволяет вычислять модулярное ядро итерационно. Также найдены точные решения для специальных значений центрального заряда $c=1+6(b-b^{-1})^2$, $b\in\mathbb{N}$. Для $c=1$ полученный результат воспроизводит формулу, полученную ранее из аналитических свойств решений уравнения Пенлеве, однако предложенное решение имеет значительно упрощенный вид.

Is global dimming and brightening in Japan limited to urban areas?
Authors: Tanaka Katsumasa , Ohmura Atsumu , Folini Doris , Wild Martin , Ohkawara Nozomu
Published: November 2016

Abstract. Worldwide observations indicate secular trends of all-sky surface solar radiation on a decadal time scale, termed global dimming and brightening. Accordingly, the observed surface radiation in Japan generally shows a strong decline until the end of the 1980s and then a recovery until around 2000. Because a substantial number of measurement stations are located within or close to populated areas, one may speculate that the observed trends are strongly influenced by local air pollution and are thus not of large-scale significance. This hypothesis poses a serious question as to what regional extent the global dimming and brightening are significant: are the global dimming and brightening truly global phenomena, or regional, or even only local? Our study focused on 14 meteorological observatories that measured all-sky surface solar radiation, zenith transmittance, and maximum transmittance. On the basis of municipality population time series, historical land use maps, recent satellite images, and actual site visits, we concluded that eight stations have been significantly influenced by urbanization, with the remaining six stations being left pristine. Between the urban and rural areas, no marked differences were identified in the temporal trends of the aforementioned meteorological parameters. Our findings suggest that global dimming and brightening in Japan occurred on a large scale, independently of urbanization.

Published: November 2016

Abstract. Novel methods of cloud detection are applied to the unique Fennec aircraft dataset, to evaluate the Met Office derived products on cloud properties over the Sahara based on the Spinning Enhanced Visible and InfraRed Imager (SEVIRI) on-board Meteosat. Two cloud mask configurations are considered, as well as the retrievals of cloud-top height, and these products are compared to airborne cloud remote sensing products acquired during the Fennec campaign in June 2011 and June 2012. Most detected clouds (67 % of the total) have a horizontal extent which is smaller than a SEVIRI pixel (3 km × 3 km). We show that, when partially cloud contaminated pixels are included, a match between the SEVIRI and aircraft datasets is found in 80 ± 8 % of the pixels. Moreover, under clear skies the datasets are shown to agree for more than 90 % of the pixels. Cloud-top height retrievals however show large discrepancies over the region, which are ascribed to limiting factors such as the cloud horizontal extent, the derived effective cloud amount, and the absorption by mineral dust.
Pathfinder: Applying graph theory for consistent tracking of
daytime mixed layer height with backscatter lidar
Authors: de Bruine Marco , Apituley Arnoud , Donovan Dave , Klein Baltink Henk , de Haij Marijn
Published: November 2016

Abstract. The height of the atmospheric boundary layer or mixing layer is an important parameter for understanding the dynamics of the atmosphere and the dispersion of trace gases and air pollution. The height of the mixing layer (MLH) can be retrieved, among other methods, from lidar or ceilometer backscatter data. These instruments use the vertical backscatter lidar signal to infer MLHL, which is feasible because the main sources of aerosols are situated at the surface and vertical gradients are expected going from the aerosol loaded mixing layer close to the ground to the cleaner free atmosphere above. Various lidar/ceilometer algorithms are currently applied, but accounting for MLH temporal development is not always well taken care of. As a result, MLHL retrievals may jump between different atmospheric layers, rather than reliably track true MLH development over time. This hampers the usefulness of MLHL time series for e.g. process studies, model validation/verification and climatology. Here, we introduce a new method "Pathfinder", which applies graph theory to simultaneously evaluate timeframes consistent with scales of MLH dynamics, leading to coherent tracking of MLH. Starting from a grid of gradients in the backscatter profiles, MLH development is followed using Dijkstra's shortest path algorithm (Dijkstra, 1959). Locations of strong gradients are connected under the condition that subsequent points on the path are limited to a restricted vertical range. The search is further guided by rules based on presence of clouds and residual layers. Applied to backscatter lidar data from Cabauw, excellent agreement is found with windprofiler retrievals for a 12-day period in 2008 (R2 = 0.90) and visual judgment of lidar data during a full year in 2010 (R2 = 0.96). These values compare favourably against other MLHL methods applied to the same lidar data set and corroborate more consistent MLH tracking by Pathfinder.
rpe v5: An emulator for reduced floating-point precision in large
numerical simulations
Authors: Dawson Andrew , Düben Peter
Published: November 2016

Abstract. This paper describes the rpe library which has the capability to emulate the use of arbitrary reduced floating-point precision within large numerical models written in Fortran. The rpe software allows model developers to test how reduced floating-point precision affects the result of their simulations without having to make extensive code changes or port the model onto specialised hardware. The software can be used to identify parts of a program that are problematic for numerical precision and to guide changes to the program to allow a stronger reduction in precision. The development of rpe was motivated by the strong demand for more computing power. If numerical precision can be reduced for an application under consideration while still achieving results of acceptable quality, computational cost can be reduced, since a reduction in numerical precision may allow an increase in performance or a reduction in power consumption. For simulations with weather and climate models, savings due to a reduction in precision could be reinvested to allow model simulations at higher spatial resolution or complexity, or to increase the number of ensemble members to improve predictions. rpe was developed with particular focus on the community of weather and climate modelling, but the software could be used with numerical simulations from other domains.
