description: We numerically construct asymptotically $AdS_4$ solutions to Einstein-Maxwell-dilaton theory. These have a dipolar electrostatic potential turned on at the conformal boundary $S^2\times \mathbb{R}_t$. We find two classes of geometries: $AdS$ soliton solutions that encode the full backreaction of the electric field on the $AdS$ geometry without a horizon, and neutral black holes that are "polarised" by the dipolar potential. For a certain range of the electric field $\mathcal{E}$, we find two distinct branches of the $AdS$ soliton that exist for the same value of $\mathcal{E}$. For the black hole, we find either two or four branches depending on the value of the electric field and horizon temperature. These branches meet at critical values of the electric field and impose a maximum value of $\mathcal{E}$ that should be reflected in the dual field theory. For both the soliton and black hole geometries, we study boundary data such as the stress tensor. For the black hole, we also consider horizon observables such as the entropy. At finite temperature, we consider the Gibbs free energy for both phases and determine the phase transition between them. We find that the $AdS$ soliton dominates at low temperature for an electric field up to the maximum value. Using the gauge/gravity duality, we propose that these solutions are dual to deformed ABJM theory and compute the corresponding weak coupling phase diagram.

description: Este estudio describe y discute un fardo funerario encontrado en Patillos 2, un sitio en la costa meridional de Chile ubicado a 58 kilómetros al sur de la ciudad de Iquique. Las momias pertenecen a la "Anker Nielsen Collection" del Museo Arqueológico de la Universidad de Chile, Iquique. El fardo contiene los cadáveres momificados de dos niños y una estólica. Para poner esta información en su contexto, hemos resumido lo que se conoce con respecto a la Cultura Chinchorro y a otras manifestaciones culturales en el norte de Chile. En cuanto a la estólica encontrada dentro del fardo funerario se trata, probablemente, de uno de los hallazgos más antiguos de Sudamérica publicado hasta la fecha. Eventualmente, su objetivo fue sujetar firmemente las momias e impedir que éstas se rompieran. Por otro lado, no se puede descartar la posibilidad de que cumplía un fin "mágico", "simbólico" o "ceremonial".

description: This paper applies variational data assimilation to inundation problems governed by the shallow water equations with wetting and drying. The objective of the assimilation is to recover an unknown time-varying wave profile at an open ocean boundary from inundation observations. This problem is solved with derivative-based optimisation and an adjoint wetting and drying scheme to efficiently compute sensitivity information. The capabilities of this approach are demonstrated on an idealised sloping beach setup in which the profile of an incoming wave is reconstructed from wet/dry interface observations. The method is robust against noisy observations if a regularisation term is added to the optimisation objective. Finally, the method is applied to a laboratory experiment of the Hokkaido-Nansei-Oki tsunami, where the wave profile is reconstructed with an error of less than 1% of the reference wave signal.

description: Se investiga la distribución en la mitología sudamericana de dos motivos incluidos en una misma temática: el motive de Orfeo describe el viaje que un ser viviente emprende hacia el reino de los muertos con el objeto de rescatar a un muerto querido, y cómo, debido a una prohibición no respetada, fracasa en su intento. El otro, describe un viaje similar, sin que el protagonista intente rescatar a un muerto. Alrededor de ambos motivos se nuclean una serie de rasgos propios de las respectivas concepciones del más allá indígenas.

description: A back action from Dirac electrons in graphene on the hybridization of radiative and evanescent fields is found as an analogy to Newton's third law. Here, the back action appears as a localized polarization field which greatly modifies an incident surface-plasmon-polariton (SPP) field. This yields a high sensitivity to local dielectric environments and provides a scrutiny tool for molecules or proteins selectively bounded with carbons. A scattering matrix is shown with varied frequencies nearby the surface-plasmon (SP) resonance for the increase, decrease and even a full suppression of the polarization field, which enables accurate effective-medium theories to be constructed for Maxwell-equation finite-difference time-domain methods. Moreover, double peaks in the absorption spectra for hybrid SP and graphene-plasmon modes are significant only with a large conductor plasma frequency, but are overshadowed by a round SPP peak at a small plasma frequency as the graphene is placed close to conductor surface. These resonant absorptions facilitate the polariton-only excitations, leading to polariton condensation for a threshold-free laser.

Les neuf Seigneurs de la nuit

description: Los antiguos mexicanos habían puesto las inquietantes horas de la noche bajo la protección de los nueve Señores de la Noche, los Yoaltetecuhtin. Si, por lo general, lo que sabemos de los dioses nos lo proporcionan las fuentes escritas, por lo que toca a los Yoaltetecuhtin, sus características se destacan más bien de una comparación entre varios manuscritos pictográficos. Se nota, en realidad, que una deidad no puede definirse aisladamente y en si misma. La secuencia linear de los Yoaltetecuhtin está lejos de agotar la complejidad de las relaciones que las nueve deidades mantienen entre ellas. Son los manuscritos pictográficos los que nos han permitido poner en evidencia las relaciones complejas, diversas y graduadas que estas deidades mantienen entre ellas. La asociación de aquellos nueve dioses con las cinco direcciones, tal como su zona de influencia tampoco son estereotipadas. El pensamiento teológico, que presidió a la elección de aquellos nueve dioses como regentes de la noche, puede tal vez percibirse a la luz de un examen de sus funciones en su totalidad.

description: En los libros de Chilam Balam de Yucatán se encuentran varias traducciones mayas de textos del Viejo Mundo. La mayor parte de ellos fueron tomados de los almanaques o reportorios que empezaron a aparecer en Nueva España poco después de la llegada de los españoles. Los libros de Kaua, Mani y Chan Kan contienen una traducción que es de especial interés por ser de un texto literario y por la manera en que se incorpora en la tradición literaria maya: ' La doncella Teodora' o 'Suhui Teodora', que tiene su origen en "Las mil y una noches". Al traducir esta historia los mayas eliminaron su comienzo novelesco y acentuaron su carácter filosófico, estableciendo conexiones entre su astronomía y la de Mesopotamia.En particular, dan relieve a las adivinanzas propuestas a Teodora, asimilándolas a la tradición maya denominada Zuyua than, que es de estirpe chamanística yse encuentra también entre los algonquines.

description: Characterizing the diffuse Galactic synchrotron emission at arcminute angular scales is needed to reliably remove foregrounds in cosmological 21-cm measurements. The study of this emission is also interesting in its own right. Here, we quantify the fluctuations of the diffuse Galactic synchrotron emission using visibility data for two of the fields observed by the TIFR GMRT Sky Survey (TGSS). We have used the 2D Tapered Gridded Estimator (TGE) to estimate the angular power spectrum $(C_{\ell})$ from the visibilities. We find that the sky signal, after subtracting the point sources, is likely dominated by the diffuse Galactic synchrotron radiation across the angular multipole range $240 \le \ell \lesssim 500$. We present a power law fit, $C_{\ell}=A\times\big(\frac{1000}{l}\big)^β$, to the measured $C_{\ell}$ over this $\ell$ range. We find that $(A,β)$ have values $(356\pm109~{\rm mK^2},2.8\pm0.3)$ and $(54\pm26~{\rm mK^2},2.2\pm0.4)$ in the two fields. For the second field, however, there is indication of a significant residual point source contribution, and for this field we interpret the measured $C_{\ell}$ as an upper limit for the diffuse Galactic synchrotron emission. While in both fields the slopes are consistent with earlier measurements, the second field appears to have an amplitude which is considerably smaller compared to similar measurements in other parts of the sky.

description: Informaciones acerca de los "esclavos lavados" en relatos como los de Sahagún, Durán y Torquemada subrayan las actividades de ciertos traficantes de Tenochtitlan quienes "lavaban" o "purificaban" esclavos para sacrificarlos al dios que representaban. Estos no eran cautivos extranjeros sino naturales de los pueblos en donde se celebraban las ceremonias. Aunque dichos mercaderes figuraban más conspicuamente, de hecho les imitaban varias otras agrupaciones sociales en el pueblo náhuatl. A causa de su origen, sus atavíos y su presentación al público, probablemente el sacrificio de los "esclavos lavados" importaba más al pueblo que el de los más numerosos cautivos.

description: This chapter of the book Planetary Ring Systems addresses the origin of planetary rings, one of the least understood processes related to planet formation and evolution. Whereas rings seem ubiquitous around giant planets, their great diversity of mass, structure and composition is a challenge for any formation scenario. Recent advances in our understanding of ring and satellite formation and destruction suggest that these processes are interconnected, so that rings and satellites may be two aspects of the same geological system. However, no single theory seems able to explain the origin of the different planetary rings known in our Solar System, and it now seems evident that rings may result from a variety of processes like giant collisions, tidal stripping of comets or satellites, as well as planet formation itself. In order to build any theory of ring formation it is important to specify physical processes that affect the long-term evolution of rings, as well as to describe the different observations that any ring formation model should explain. This is the topic of section 2. In section 3, we focus our attention on Saturn's rings and their main properties, and then discuss the pros and cons of a series of ring formation models. We also discuss the link between rings and satellites. In section 4, we extend the discussion to the other giant planets (Jupiter, Uranus, and Neptune). Section 5 is devoted to new types of rings -- the recent discovery of rings orbiting small outer Solar System bodies (Centaurs), and the possible rings around extrasolar planets. In section 6, we conclude and try to identify critical observations and theoretical advances needed to better understand the origin of rings and their significance in the global evolution of planets.

description: Como una protesta y una apelación contra el acuerdo capitular de no favorecer con apoyo material la continuación de su "Historia", Sahagún envió al Papa San Pío V un "Breve Compendio" de su obra. El "Breve Compendio", que últimamente formaba parte del Libro II del Codice Florentino, contenía dieciséis "Fiestas Movibles". El origen de dichas fiestas se encuentra en el texto náhuatl del Libro V (Libro IV del Códice Florentino) del Manuscrito de Tlatelolco. Las "Fiestas Movibles" guardan relación por un lado con el tonalpohualli y, por el otro, se asemejan a los ritos de los dieciocho meses del año. El presente estudio trata de averiguar el razonamiento de Sahagún para discutirlas por separado.

Scrutinizing the Higgs quartic coupling at a future 100 TeV proton-proton collider with taus and b-jets

description: The Higgs potential consists of an unexplored territory in which the electroweak symmetry breaking is triggered, and it is moreover directly related to the nature of the electroweak phase transition. Measuring the Higgs boson cubic and quartic couplings, or getting equivalently information on the exact shape of the Higgs potential, is therefore an essential task. However, direct measurements beyond the cubic self-interaction of the Higgs boson consist of a huge challenge, even for a future proton-proton collider expected to operate at a center-of-mass energy of 100 TeV. We present a novel approach to extract model-independent constraints on the triple and quartic Higgs self-coupling by investigating triple Higgs-boson hadroproduction at a center-of-mass energy of 100 TeV, focusing on the $ττb \bar{b} b \bar{b}$ channel that was previously overlooked due to a supposedly too large background. It is thrown into sharp relief that the assist from transverse variables such as $m_{T2}$ and a boosted configuration ensures a high signal sensitivity. We derive the luminosities that would be required to constrain given deviations from the Standard Model in the Higgs self-interactions, showing for instance that a $2σ$ sensitivity could be achieved for an integrated luminosity of 30 ab$^{-1}$ when Standard Model properties are assumed. With the prospects of combining these findings with other triple-Higgs search channels, the Standard Model Higgs quartic coupling could in principle be reached with a significance beyond the $3σ$ level.

description: The paper presents the study of waves in a structured geometrically chiral solid. A special attention is given to the analysis of the Bloch-Floquet waves in a doubly periodic high-contrast lattice containing tilted resonators. Dirac-like dispersion of Bloch waves in the structure is identified, studied and applied to wave-guiding and wave-defect interaction problems. The work is extended to the transmission problems and models of fracture, where localisation and edge waves occur. The theoretical derivations are accompanied with numerical simulations and illustrations.

description: The Letter reports an experimental observation of the classical version of valley polarized states in a two-dimensional hexagonal sonic crystal, where the inversion-symmetry breaking of scatterers induces an omnidirectional frequency gap. The acoustic valley states, which carry specific linear momenta and orbital angular momenta, were selectively excited by external Gaussian beams and conveniently confirmed by the pressure distribution outside the crystal, according to the criterion of momentum conservation. The vortex nature of such intriguing crystal states was directly characterized by scanning the phase profile inside the crystal. In addition, we observed a peculiar beam splitting phenomenon, in which the separated beams are constructed by different valleys and locked to the opposite vortex chirality. The exceptional sound transport, encoded with valley-chirality locked information, may serve as the basis of designing conceptually novel acoustic devices with unconventional functions.

These letters, spanning 1921 and 1922, primarily discuss Read’s work as a Readers and Writers columnist for the magazine in that time. In these letters Orage also frequently mentions P. D. Ouspensky, who studied under philosopher G. I. Gurdjieff. In 1922 Orage sold “The New Age” and moved to Paris in order to also study under Gurdjieff. In this letter Orage refuses a MS for New Age magazine because he has "foresworn the publication of anything realistic about the war".

description: A new algorithm is developed allowing the Monte Carlo study of a 1 + 1 dimensional theory in real time. The main algorithmic development is to avoid the explicit calculation of the Jacobian matrix and its determinant in the update process. This improvement has a wide applicability and reduces the cost of the update in thimble-inspired calculations from O(N^3) to less than O(N^2). As an additional feature, the algorithm leads to improved Monte Carlo proposals. We exemplify the use of the algorithm to the real time dynamics of a scalar ϕ^4 theory with weak and strong couplings.

Una causa para esta situación tan contraria a la encontrada por los españoles en el vecino Valle de México parece haber sido la imposibilidad tecnológica de conducir, sin excesivas pérdidas, el agua de los arroyos – generalmente poco abundante-por las grandes distancias necesarias y a través de un terreno arenoso o accidentado. Esto explica la gran importancia que para Huejotzingo tenía el cercano Valle de Atlixco, en el que una población campesina dependiente producía con cultivos de riego los excedentes necesarios para el consumo en el área clave.

description: We outline a novel chiral kinetic theory framework for systematic computations of the Chiral Magnetic Effect (CME) in ultrarelativistic heavy-ion collisions. The real part of the fermion determinant in the QCD effective action is expressed as a supersymmetric world-line action of spinning, colored, Grassmanian point particles in background gauge fields, with equations of motion that are covariant generalizations of the Bargmann-Michel-Telegdi and Wong equations. Berry's phase is obtained in a consistent non-relativistic adiabatic limit. The chiral anomaly, in contrast, arises from the phase of the fermion determinant; its topological properties are therefore distinct from those of the Berry phase. We show that the imaginary contribution to the fermion determinant too can be expressed as a point particle world-line path integral and derive the corresponding anomalous axial vector current. Our results can be used to derive a covariant relativistic chiral kinetic theory including the effects of topological fluctuations that has overlap with classical-statistical simulations of the CME at early times and anomalous hydrodynamics at late times.

description: Thermodynamics of the near extremal black p-branes can be described by collective motions of gravitationally interacting branes. This proposal is called the p-soup model. In this paper, we check this proposal in the case of black brane system which is asymptotically Friedmann-Lemaitre-Robertson-Walker universe in an infinite distance. As a result, we can show that the gravitationally interacting branes explain free energy, entropy, temperature and other physical quantities in these systems. This implies that the microstates of this kind of brane system can be also understood in the p-soup model.

description: Basándose en el trasfondo de un concepto general de evolución social y estatal, se interpretan las culturas prehispánicas de México según cuatro fases de desarrollo progresivo, partiendo de sistemas simples hasta llegar a formas de organización complejas. La primera fase es la de una comunidad agrícola unitaria y autárquica, la segunda la de una comunidad autárquica orientada hacia un centro político-religioso, la tercera la de una comunidad urbana-agraria con una estatización formalizada, y la cuarta la de un estado unido ya no en lo económico sino, principalmente, en lo político.

description: Factorization of the differential expansion coefficients for HOMFLY-PT polynomials of double braids, discovered in arXiv:1606.06015 in the case of rectangular representations $R$, is extended to the first non-rectangular representations $R=[2,1]$ and $R=[3,1]$. This increases chances that such factorization will take place for generic $R$, thus fixing the shape of the DE. We illustrate the power of the method by conjecturing the DE-induced expression for double-braid polynomials for all $R=[r,1]$. In variance with rectangular case, the knowledge for double braids is not fully sufficient to deduce the exclusive Racah matrix $\bar S$ -- the entries in the sectors with non-trivial multiplicities sum up and remain unseparated. Still a considerable piece of the matrix is extracted directly and its other elements can be found by solving the unitarity constraints.

description: Part of a collection of correspondence between Sir Herbert Read and Alfred Richard Orage. Orage is most well-known for editing the magazine “The New Age”. These letters, spanning 1921 and 1922, primarily discuss Read’s work as a Readers and Writers columnist for the magazine in that time. In these letters Orage also frequently mentions P. D. Ouspensky, who studied under philosopher G. I. Gurdjieff. In 1922 Orage sold “The New Age” and moved to Paris in order to also study under Gurdjieff. In this letter, Orage postpones the publication of T. E. Hulme. He also gives Read the details on where Ouspensky will lecture.
Anti-Kibble-Zurek behavior of a noisy transverse-field XY chain and its quantum simulation with two-level systems

description: We study the dynamics of a transverse-field XY chain driven across quantum critical points by noisy control fields. We characterize the defect density as a function of the quench time and the noise strength, and demonstrate that the defect productions for three quench protocols with different scaling exponents exhibit the anti-Kibble-Zurek behavior, whereby slower driving results in more defects. The protocols are quenching through the boundary line between paramagnetic and ferromagnetic phases, quenching across the isolated multicritical point and along the gapless line, respectively. We also show that the optimal quench time to minimize defects scales as a universal power law of the noise strength in all the three cases. Furthermore, by using quantum simulation of the quench dynamics in the spin system with well-designed Landau-Zener crossings in pseudo-momentum space, we propose an experimentally feasible scheme to test the predicted anti-Kibble-Zurek behavior of this noisy transverse-field XY chain with two-level systems under controllable fluctuations.

description: Este estudio analiza el significado de un motivo que ha sido identificado en los códices pictóricos y en la escultura del México antiguo como un símbolo acuático: es el círculo alrededor del ojo o el "anteojo" . Cuando este círculo se representa en forma de relieve - por ejemplo en el dios del agua y de la tierra, Tlaloc – efectivamente simboliza el agua. También aparece a veces en forma independiente como la insignia abreviada de Tlaloc, o como el chalchihuitl, símbolo del agua y de lo precioso. Los círculos pintados alrededor de los ojos, sin embargo, seguido se confunden con el "anteojo" y son típicos de dioses de un carácter diferente. Están asociados con la guerra, el fuego y el sol, y con los dioses Camaxtli, Tezcatlipoca y Huitzilopochtli.

description: Rose is one of the most important cut flowers in Ethiopia produced mostly for export markets. Maintaining the postharvest life is the most challenging issue for most of the floricultural enterprises in the country. Two sets of experiments were therefore conducted in Tana Flora PLC farm, one of the biggest cut rose producers in Bahir Dar, Northwestern Ethiopia with the objectives of identifying the appropriate concentration of aluminum sulfate as pulsing preservative to maintain the vase life of export oriented rose flowers. In the first set, aluminum sulfate alone and in combination with calcium hypochlorite at different concentrations including the experience of Tana Flora PLC, sucrose and distilled water as control were tested for their influence on physiological status of `Maracuja` rose flowers. In the second set, the best performed pulsing preservative (aluminum sulfate alone) was tested at four concentrations (0ppm, 125ppm, 250ppm and 375ppm) to identify the optimum concentration. After pulsing for about 30 hours, six cut flowers were put in 250 ml glass flask containing distilled water. The flasks with flowers were arranged in Complete Randomized Design with three replications and kept in vase life testing room of Tana Flora PLC. According to the results obtained, aluminum sulfate at the concentration of 250ppm was the best in prolonging the vase life, in producing bigger flower head and maintaining the freshness of flowers. The reduction in percent fresh weight during the vase life of flowers was minimal in 250ppm aluminum sulfate pulsed flowers. The prolonged vase life of aluminum pulsed flowers is due to better water uptake and thus stabilized water balance in the flowers as observed in this study. Thus, it is advised to incorporate aluminum sulfate in flower holding solution at the concentration of 250ppm to maintain the freshness and vase life of export oriented rose flowers and those for local market in the study area.

description: BACKGROUND: Spatial accessibility is an essential component of access to healthcare for populations. Poor accessibility can lead the most socially disadvantaged populations to pay the highest share to reach health services (Gu et al., 2019). The AMORE Platform was created with the intention to be an easily understandable source of information for decision makers to improve Spatial accessibility, however no further investigation has been conducted to evaluate the functionality of the platform or its potential use in the decision- making process for enhancing spatial accessibility to healthcare services, from the standpoint of stakeholders in the specific context of Colombia. OBJECTIVES: Evaluate the potential of the AMORE platform to improve spatial accessibility to healthcare services in the Colombian context by examining the factors that affect its functionality and feasibility for implementation, based on stakeholder’s perceptions. METHODS: This study will consist of exploratory qualitative research. Semi structure interviews with pre-determined themes to explore in depth the perception and intention to use of an innovative data dashboard focused on spatial accessibility in urban healthcare services. RESULTS & DISCUSSION: The AMORE Collaborative Platform is presented as a dashboard with clear potential to support decision-making processes, not only for the development of public policies but also for improving internal processes in private organizations, increasing information available for academia, and enabling oversight by citizens and patient groups. The implementation of the platform will require a joint effort from the development team, which will need to identify strategic allies in multiple sectors.
Inhomogeneous screening of gate electric field by interface states in graphene FETs

description: The electronic states at graphene-SiO$_2$ interface and their inhomogeneity was investigated using the back-gate-voltage dependence of local tunnel spectra acquired with a scanning tunneling microscope. The conductance spectra show two, or occasionally three, minima that evolve along the bias-voltage axis with the back gate voltage. This evolution is modeled using tip-gating and interface states. The energy dependent interface states' density, $D_{it}(E)$, required to model the back-gate evolution of the minima, is found to have significant inhomogeneity in its energy-width. A broad $D_{it}(E)$ leads to an effect similar to a reduction in the Fermi velocity while the narrow $D_{it}(E)$ leads to the pinning of the Fermi energy close to the Dirac point, as observed in some places, due to enhanced screening of the gate electric field by the narrow $D_{it}(E)$

description: Las fuentes mesoamericanas que tratan de las edades o Soles del universo mencionan a veces cuatro, otras veces cinco Soles (incluido cada vez el Sol actual). Las versiones con cuatro Soles son las más difundidas y parecen las más antiguas. Presentan a los hombres de las edades pasadas como capaces de realizaciones importantes y reflejan una idea de progreso, de evolución. Las versiones con cinco Soles, en cambio, niegan toda historia o progreso antes del Sol presente. Parecen más bien aztecas o mexicas y son construidas a partir de los datos de las versiones con cuatro Soles. Por otra parte, en la mayoría de las fuentes la historia del mundo empieza alrededor del siglo VIII mientras que en algunas otras, con fuerte influencia mexica, comienza alrededor del año 1100, al mismo tiempo que el Quinto Sol. El Quinto Sol, entonces, probablemente es una creación de los aztecas y de los mexicas en particular. Ellos lo impusieron a pueblos que se consideraban en la cuarta edad, o sea en el Sol tolteca de Quetzalcoatl.
