La “fuga” de Don Proti (cuento) o La ubicación de los laicos de puesto nombrado en los actos oficiales de la Iglesia Católica
Authors: Martinez Cazalla Maria Dolors 
Published: February 2018

Dado que el protocolo tiene por objeto el ordenar personas, documentos, símbolos, espacios y tiempos, para así poder cumplir con su objetivo, comunicar, va de suyo que si se ordena de manera inadecuada a los deseos de comunicación, lo que el receptor recibirá no será lo que se ha querido comunicar. Así pues, la ponencia tendrá por objetivo, dentro del marco del protocolo eclesiástico, mostrar la importancia que tiene el escoger una u otra forma a la hora de ordenar/ubicar a los laicos de puesto nombrado en los actos oficiales de la Iglesia Católica. Es decir, ‘¿Cómo se ordenan y por qué?’ y ‘¿Qué está comunicando dicha ordenación?’. Será una invitación a reflexionar juntos sobre ‘¿dónde sentar a un laico de puesto nombrado en un acto oficial de la Iglesia Católica?’, apoyándonos en todo momento tanto en la tradición, usos y costumbres, como en textos oficiales de la Iglesia Católica. El “cuento” (La “fuga” de Don Proti) será el estilo literario escogido para presentar las posibles ordenaciones y lo que respectivamente están comunicando. Éste permite crear una ficción sobre un supuesto acto posible y plausible, teniendo la ventaja de poder expresarse con mayor libertad sin por ello herir sensibilidades. Asimismo, se tratará de un cuento abierto, donde serán propuestos tres posibles, y no únicos, finales, dejando al lector la libertad de escoger el que le pareciese más acertado y/o el que más le pudiera complacer así como la de pensar a partir de lo presentado otras variaciones y/o permutaciones posibles.The object of the protocol is to order persons, documents, symbols, places and moments to achieve its objective: to communicate. It is evident that if we do not order in accordance with our wishes of communication, what the recipient will receive will not be what we wanted to communicate. Therefore, this presentation, included in the framework of the ecclesiastical protocol, has as objective to show how important is to choose the placement of the lay people appointed by the Holy See for the official events of the Catholic Church. In other words, ‘How to order them and why?’ and ‘What is this order saying?’ This presentation is an invitation to think together about ‘where do we place the lay people appointed by the Holy See for an official event of the Catholic Church?’ We should always base our answer on the tradition and customs and, on the official texts of the Catholic Church.We have chosen the story -The “flight” of Mr. Proti- as the style to show the possible orders and what each one is saying. We have opted for this style because the story allows for creating a fiction about a possible and admissible act. Besides stories permits more freedom of expression without offending sensibilities. This is an open story, where three possible ends are proposed, but there may be more. The reader is free to choose the one he thinks is better and/or he enjoys the most. Still he remains free for thinking other possible variations and/or permutations.

La importancia del ceremonial en la diplomacia durante el reinado de Felipe V
Authors: Panizo Alonso Julio Manuel 
Published: February 2018

La relación de las diferentes monarquías con las casas reales de su entorno siempre ha sido un elemento fundamental para el ejercicio de la política exterior, afectando en muchos casos por los vínculos familiares a las relaciones familiares. La presencia de representantes de los demás monarcas en las diferentes cortes desde finales del siglo XV es habitual y el trato que se daba a esos representantes era una forma más de gestionar esa diplomacia de la época.La disparidad de criterios y costumbres en ese trato con los embajadores hace que en muchas de las cortes se dicten libros de etiquetas en donde se especifica de forma detallada las costumbres a seguir en este trato, así como en la participación de las diferentes ceremonias de la Corte. La llegada de Felipe V al trono, introdujo nuevas costumbres en la monarquía española como fruto de su origen francés y que al igual que afectaron a la actividad de la corte también se visualizaron en esas costumbres con los representantes de otras monarquías.__________________The relationship of the different monarchies with the royal houses of their environment has always been a fundamental element for the exercise of foreign policy, affecting in many cases by family ties to family relationships. The presence of representatives of the other monarchs in the different courts since the end of the 15th century is common and the treatment given to these representatives was one more way of managing that diplomacy of the time.The disparity of criteria and customs in this deal with the ambassador’s makes that in many of the courts labels are dictated where the customs to be followed in this deal are specified in detail, as well as in the participation of the different ceremonies of the Cut. The arrival of Felipe V to the throne, introduced new customs in the Spanish monarchy like fruit of its French origin and that like they affected to the activity of the court also they were visualized in those customs with the representatives of other monarchies.
Le droit romain et la servitude aux Antilles
Authors: Mignot Dom A. 
Published: February 2018

De nombreux auteurs ont fait allusion au droit romain pour expliquer la logique - si tant est qu’il y ait une logique - du fameux Code Noir de 1685. A vrai dire il conviendrait de se reporter non seulement aux travaux préparatoires, voire à l’expérience française du servage issue de la féodalité, mais encore, à notre avis, il paraît nécessaire de suivre l’application et l’evolution de l’institution servile aux XVIIe et surtout au XVIIIe siècle. En quelque sorte, la question principale est de savoir si la triste expérience de la servitude antillaise correspond à l’esclavage de l’Antiquité classique romaine ou encore à celui de l’antiquité tardive (IVe-VIe s. - Romanité). Nous exposerons cette problématique en trois points. Le premier a trait à l’évolution de l’esclavage à la fin de l’Antiquité (1) ; le second point portera essentiellement sur le phénomène de résurgence de la servitude gréco-romaine à la fin du Grand Siècle (2) ; enfin, outre les parallélismes de forme ou de fond, on s’attachera à dégager les signes communs d’évolution entre le « modèle » des Anciens et l’application des Modernes (3).
Gender-associated factors for frailty and their impact on hospitalization and mortality among community-dwelling older adults: a cross-sectional population-based study
Authors: Zhang Qin , Guo Huanyu , Gu Haifeng , Zhao Xiaohong 
Published: February 2018

Background
Frailty associated with aging increases the risk of falls, disability, and death. We investigated gender-associated factors for frailty.

Methods
Data of 3,079 geriatric subjects were retrieved from the National Health and Nutrition Examination Survey (NHANES) 2007–2010 database. After excluding 1,126 subjects with missing data on frailty, medical history and survival, data of 1,953 patients were analyzed. Main endpoints were frailty prevalence, mortality rates and causes of death.

Results
Frailty prevalence was 5.4% in males, 8.8% in females. Significant risk factors for geriatric frailty in males were being widowed/divorced/separated, low daily total calorie intake, physical inactivity, sleeping >9 h, smoking and hospitalization history; and in females were obesity, physical inactivity, sleeping <6 h, family history of diabetes and heart attack, and hospitalization history. Frail subjects had higher mortality rates (22.5% male; 8.5% female) than pre-frail (8.7% male; 6.4% female) and non-frail (5.4% male; 2.5% female). Main causes of death were heart diseases (41%) and chronic lower respiratory diseases (23.0%) in males and nephritis/nephrosis (32.3%) and chronic lower respiratory diseases (17.6%) in females.

Discussion
Factors associated with frailty differ by gender, with higher frailty prevalence in females and higher mortality in males. Gender-associated factors for frailty identified in this study may be useful in evaluating frailty and guiding development of public health measures for prevention.

Key Message
Common predictive factors for frailty among older adults of both genders, including more frequent previous hospitalizations, physical inactivity, and certain gender-associated factors for frailty, are consistent with results of other NHANES studies in which self-reported higher levels of illness and sedentary behavior were directly associated with frailty.
Long non‐coding RNA CASC15 regulates gastric cancer cell proliferation, migration and epithelial mesenchymal transition by targeting CDKN1A and ZEB1

Long non‐coding RNA (lncRNA) is responsible for a diverse range of cellular functions, such as transcriptional and translational regulation and variance in gene expression. The lncRNA CASC15 (cancer susceptibility candidate 15) is a long intergenic non‐coding RNA (lincRNA) locus in chromosome 6p22.3. Previous research shows that lncRNA CASC15 is implicated in the biological behaviors of several cancers such as neuroblastoma and melanoma. Here, we aimed to explore in detail how CASC15 contributes to the growth of gastric cancer (GC). As predicted, the expression of CASC15 was enriched in GC tissues and cell lines as compared with healthy tissues and cells using qRT‐PCR. The Kaplan–Meier method was used to demonstrate that high expression of CASC15 is linked to a poor prognosis for patients suffering from GC. Additionally, functional experiments proved that the down‐ or up‐regulation of CASC15 inhibited or facilitated cell proliferation via the induction of cell cycle arrest and apoptosis, and also suppressed or accelerated cell migration and invasion by affecting the progression of the epithelial‐to‐mesenchymal transition (EMT). In vivo experiments showed that the knockdown of CASC15 lessened the tumor volume and weight and influenced the EMT process. This was confirmed by western blot assays and immunohistochemistry, indicating impaired metastatic ability in nude mice. CASC15 involvement in the tumorigenesis of GC occurs when CASC15 interacts with EZH2 and WDR5 to modulate CDKN1A in nucleus. Additionally, the knockdown of CASC15 triggered the silencing of ZEB1 in cytoplasm, which was shown to be associated with the competitive binding of CASC15 to miR‐33a‐5p.
On the Diffusion Rates of Electron Bounce Resonant Scattering by Magnetosonic Waves
Authors: Maldonado Armando A. , Chen Lunjin 
Published: February 2018

AbstractMagnetosonic waves have been demonstrated as effective for bounce resonant scattering. Electron scattering rates due to bounce resonance interaction with magnetosonic waves are derived in a general form, where the effects of the finite Larmor radius, of violation in the first adiabatic invariant, and of latitudinal wave power distribution are considered. Such bounce resonance diffusion coefficients are important, but missing, from radiation belt modeling. Additionally, we provide a parametric study on the electron energy and equatorial pitch angle, magnetosonic wave, and background parameters to identify the factors that determine effective bounce resonant scattering.
Controls on the T Phase Energy Fluxes Recorded on Juan Fernandez Island by Continental Seismic Wave Paths and Nazca Bathymetry
Authors: Sáez Miguel , Ruiz Sergio 
Published: February 2018

AbstractT phases from 54 South American earthquakes with Mw > 5.2 are observed at a broadband station on Juan Fernandez Island. We computed the T phase energy flux (TPEF) values of the seismograms. The TPEF values show a large dispersion that can be explained by considering the tectonic characteristics of the South American plate and the Nazca plate bathymetry. The TPEFs generated by the 2015 Illapel and 2017 Valparaíso seismic sequences were controlled by the positions of the interface events along the dip. The central and downdip interplate earthquakes were more efficient in the generation of T phases than the near‐trench interplate earthquakes (depths of <15 km). The variations in the generation efficiency with depth are explained by the continental raypaths of the body waves and the incidence angles of waves entering the sound fixing and ranging channel. Additionally, we observed differences in the TPEFs from both earthquake sequences that were controlled by seamounts atop the Nazca plate along the T phase paths.
The Origin of the Moon Within a Terrestrial Synestia

Published: February 2018

AbstractThe giant impact hypothesis remains the leading theory for lunar origin. However, current models struggle to explain the Moon's composition and isotopic similarity with Earth. Here we present a new lunar origin model. High‐energy, high‐angular‐momentum giant impacts can create a post‐impact structure that exceeds the corotation limit, which defines the hottest thermal state and angular momentum possible for a corotating body. In a typical super‐corotation‐limit body, traditional definitions of mantle, atmosphere, and disk are not appropriate, and the body forms a new type of planetary structure, named a synestia. Using simulations of cooling synestias combined with dynamic, thermodynamic, and geochemical calculations, we show that satellite formation from a synestia can produce the main features of our Moon. We find that cooling drives mixing of the structure, and condensation generates moonlets that orbit within the synestia, surrounded by tens of bars of bulk silicate Earth vapor. The moonlets and growing moon are heated by the vapor until the first major element (Si) begins to vaporize and buffer the temperature. Moonlets equilibrate with bulk silicate Earth vapor at the temperature of silicate vaporization and the pressure of the structure, establishing the lunar isotopic composition and pattern of moderately volatile elements. Eventually, the cooling synestia recedes within the lunar orbit, terminating the main stage of lunar accretion. Our model shifts the paradigm for lunar origin from specifying a certain impact scenario to achieving a Moon‐forming synestia. Giant impacts that produce potential Moon‐forming synestias were common at the end of terrestrial planet formation.
Fluid Topology in Pore Scale Two‐Phase Flow Imaged by Synchrotron X‐ray Microtomography
Authors: Khanamiri Hamid Hosseinzade , Torsæter Ole 
Published: February 2018

AbstractA flow experiment including drainage and imbibition by water and surfactant was performed on a water‐wet Berea sandstone. The three‐dimensional (3‐D) pore scale changes of the fluid configuration were captured under flow using synchrotron X‐ray computed microtomography. Euler characteristic of ganglia and connected pathway was calculated to study topology of these entities. In addition, Betti numbers and volumes of the ganglia and connected pathway were calculated to study their contribution in the flow. Results showed that Euler characteristic of the ganglia and the whole phase (ganglia plus connected pathway) versus saturation exhibited hysteresis in imbibition and drainage. However, the Euler characteristic of the connected pathway versus saturation had insignificant hysteresis in imbibition and drainage. Results of the Betti numbers and volume changes in nonwetting ganglia and connected pathway showed that the ganglia contributed to the flow by creating internal redundant connections, volume exchange with the connected pathway and saturation change. Further, the number of redundant connections in nonwetting connected pathway increased in drainage and decreased in imbibition, smoothly in both cases, with insignificant sensitivity to the changes in rate and interfacial tension.
Contributions of Dynamic and Thermodynamic Scaling in Subdaily Precipitation Extremes in India
Authors: Ali Haider , Mishra Vimal 
Published: February 2018

AbstractDespite the importance of subdaily precipitation extremes for urban areas, the role of dynamic and thermodynamic scaling in changes in precipitation extremes in India remains poorly constrained. Here we estimate contributions from thermodynamic and dynamic scaling on changes in subdaily precipitation extremes for 23 urban locations in India. Subdaily precipitation extremes have become more intense during the last few decades. Moreover, we find a twofold rise in the frequency of subdaily precipitation extremes during 1979–2015, which is faster than the increase in daily precipitation extremes. The contribution of dynamic scaling in this rise in the frequency and intensity of subdaily precipitation extremes is higher than the thermodynamic scaling. Moreover, half‐hourly precipitation extremes show higher contributions from the both thermodynamic (~10%/K) and dynamic (~15%/K) scaling than daily (6%/K and 9%/K, respectively) extremes indicating the role of warming on the rise in the subdaily precipitation extremes in India. Our findings have implications for better understanding the dynamic response of precipitation extremes under the warming climate over India.
Fluorescence Manipulation of Carbon Dots by 1D Photonic Crystals

Published: February 2018

AbstractLuminescent carbon dots (CDs) hold great potential in the light‐emitting diode (LED) application on account of their high photostability and eco‐friendliness. The utilization of LED in display requires pixel sources of pure and saturated colors. To optimize the broad emission of CDs, a versatile approach for narrowing the fluorescence of CDs via 1D photonic crystals (1DPCs) is developed. The 1DPC reported herein has sandwiched a thicker layer of CDs in the middle of two hybrid periodic laminar structures, yielding a transmittance dip. CDs are utilized as prepared without further purification. The transmittance dip is able to be tuned by altering the thickness of layers. Such background thus permits the adjustment of structural properties to narrow the full width at half‐maximum (FWHM) and manipulate the emission color of LED device (composed of a GaN chip and the 1DPC). The transmittance dip enhances the fluorescence intensity, which is quite different from the traditional color filter such as liquid crystal. Furthermore, the mechanism of fluorescent manipulation is confirmed by the assistance of a finite‐difference time‐domain (FDTD) simulation. Such fluorescence tuning not only molds emission properties of CDs but also provides possibilities for the construction of more efficient devices for color purification.

Published: February 2018

AbstractHierarchical hollow NiCo2S4 microspheres with a tunable interior architecture are synthesized by a facile and cost‐effective hydrothermal method, and used as a cathode material. A three‐dimensional (3D) porous reduced graphene oxide/Fe2O3 composite (rGO/Fe2O3) with precisely controlled particle size and morphology is successfully prepared through a scalable facile approach, with well‐dispersed Fe2O3 nanoparticles decorating the surface of rGO sheets. The fixed Fe2O3 nanoparticles in graphene efficiently prevent the intermediates during the redox reaction from dissolving into the electrolyte, resulting in long cycle life. KOH activation of the rGO/Fe2O3 composite is conducted for the preparation of an activated carbon material–based hybrid to transform into a 3D porous carbon material–based hybrid. An energy storage device consisting of hollow NiCo2S4 microspheres as the positive electrode, the 3D porous rGO/Fe2O3 composite as the negative electrode, and KOH solution as the electrolyte with a maximum energy density of 61.7 W h kg−1 is achieved owing to its wide operating voltage range of 0–1.75 V and the designed 3D structure. Moreover, the device exhibits a high power density of 22 kW kg−1 and a long cycle life with 90% retention after 1000 cycles at the current density of 1 A g−1.
