description: In this Letter we establish a relationship between symmetric SU(2) Yang--Mills instantons and metrics with Spin(7)-holonomy. Our method is based on a slight extension of that of Bryant and Salamon developed to construct explicit manifolds with special holonomies in 1989. More precisely, we prove that making use of symmetric SU(2) Yang--Mills instantons on Riemannian spin-manifolds, we can construct metrics on the chiral spinor bundle whose holonomies are within Spin(7). Moreover if the resulting space is connected, simply connected and complete, the holonomy coincides with Spin(7). The basic example is the metric constructed on the chiral spinor bundle of the round four-sphere by using a generic SU(2)-instanton of unit action; hence it is a five-parameter deformation of the Bryant--Salamon example, also found by Gibbons, Page and Pope.

description: El término desarrollo rural esconde numerosos matices y significados. Sin duda, su frecuente utilización pone de manifiesto la revalorización y el cambio de mentalidad que se va imponiendo sobre los espacios rurales. Con este artículo se pretende analizar el desarrollo que en particular tiene lugar en las zonas de montaña, de clara vocación forestal, su evolución y relación con el contexto económico y social actual, y reflexionar sobre su futuro aportando pautas de lo que debería ser un desarrollo rural territorial y sostenible.......In this article we try to analyze the development in mountain areas, (where we find important forest resources), its relation with the economic and social situation in the present moment, its evolution in the last years, as well as its future and the guide lines about a right way of rural development: sustainable and centered in the local community and the territory.

description: The interaction among spreading processes on a complex network is a nontrivial phenomenon of great importance. It has recently been realized that cooperative effects among infective diseases can give rise to qualitative changes in the phenomenology of epidemic spreading, leading for instance to abrupt transitions and hysteresis. Here we consider a simple model for two interacting pathogens on a network and we study it by using the message-passing approach. In this way we are able to provide detailed predictions for the behavior of the model in the whole phase-diagram for any given network structure. Numerical simulations on synthetic networks (both homogeneous and heterogeneous) confirm the great accuracy of the theoretical results. We finally consider the issue of identifying the nodes where it is better to seed the infection in order to maximize the probability of observing an extensive outbreak. The message-passing approach provides an accurate solution also for this problem.

description: The emergence of glassy behavior of electrons is investigated for systems close to the disorder and/or interaction-driven metal-insulator transitions. Our results indicate that Anderson localization effects strongly stabilize such glassy behavior, while Mott localization tends to suppress it. We predict the emergence of an intermediate metallic glassy phase separating the insulator from the normal metal. This effect is expected to be most pronounced for sufficiently disordered systems, in agreement with recent experimental observations.

description: La comarca de Els Ports, ubicada en el extremo NW de la provincia de Castelló, asiste en apenas doscientos años a dos realidades contrapuestas en relación con su paisaje agroforestal, característico de la montaña media mediterránea. El insólito crecimiento demográfico obligó a realizar unos masivos rompimientos de tierras con la finalidad de obtener alimentos suficientes para la población desde el último tercio del siglo XVIII. Desde entonces se asiste a una fuerte intervención antrópica en el paisaje, que es modelado desde una perspectiva agrícola dominante. Ni tan siquiera un monte de utilidad pública como Pereroles, sometido a un régimen de aprovechamiento comunal desde la Edad Media, consigue eludir esta dinámica. Los cambios actuales están vinculados a la continuada pérdida de población, a un fuerte éxodo rural, así como a un consecuente abandono de terrenos cultivados. El paisaje ha recuperado su “dinámica natural” después de varias décadas de una intensa explotación humana, por lo que los bosques han iniciado un lento proceso de recolonización del territorio........Els Ports region, which is located at the north-west end of the Castellon province, has gone through two opposing beings for scarcely two hundred years in relation to the agroforestry landscape that is characteristic of the median Mediterranean mountains. Since the last third of XVIII century, its unwonted population growth forced people to accomplish large-scale land breaking in order to procure enough food for this community. Since then there has been a grave anthropoid intervention on its scenery, which has been shaped in an overriding future agricultural development. Not even a public profitable mountain such as Pereroles, which was subjected to a communal supplying system, can ward off this dynamic. Present changes are bound to the continual loss of population, the strong drift from the countryside, and the consequent absence from the cultivated lands. This landscape recovered its 'natural dynamic' after enduring the intense human exploitation for several decades. Thus, woods have started a gradual process for recolonizing the territory.

description: We study the Holstein model of spinless fermions, which at half-filling exhibits a quantum phase transition from a metallic Tomonaga-Luttinger liquid phase to an insulating charge-density-wave (CDW) phase at a critical electron-phonon coupling strength. In our work, we focus on the real-time evolution starting from two different types of initial states that are CDW ordered: (i) ideal CDW states with and without additional phonons in the system and (ii) correlated ground states in the CDW phase. We identify the mechanism for CDW melting in the ensuing real-time dynamics and show that it strongly depends on the type of initial state. We focus on the far-from-equilibrium regime and emphasize the role of electron-phonon coupling rather than dominant electronic correlations, thus complementing a previous study of photo-induced CDW melting [H. Hashimoto and S. Ishihara, Phys. Rev. B 96, 035154 (2017)]. The numerical simulations are performed by means of matrix-product-state based methods with a local basis optimization (LBO). Within these techniques, one rotates the local (bosonic) Hilbert spaces adaptively into an optimized basis that can then be truncated while still maintaining a high precision. In this work, we extend the time-evolving block decimation (TEBD) algorithm with LBO, previously applied to single-polaron dynamics, to a half-filled system. We demonstrate that in some parameter regimes, a conventional TEBD method without LBO would fail. Furthermore, we introduce and use a ground-state density-matrix renormalization group method for electron-phonon systems using local basis optimization. In our examples, we account for up to $M_{\rm ph} = 40$ bare phonons per site by working with $O(10)$ optimal phonon modes.

description: La mayoría de los estudios sobre la industria agroalimentaria presentan un enfoque macroeconómico. Las investigaciones con un enfoque estratégico, que analizan la realidad de las empresas que operan en este sector, son escasas. El presente trabajo compara los sectores agroalimentarios de dos regiones europeas de interior: Castilla-La Mancha y Beira Interior. El mismo se efectúa dentro del marco teórico propuesto por el modelo de las Fuerzas Competitivas de Porter (1982) y mediante el análisis de la percepción de los propios gerentes. A través de entrevistas en profundidad, mantenidas con los directivos de 20 empresas de ambas regiones, se obtiene su visión acerca de la incidencia de las diversas fuerzas competitivas sobre la competitividad del sector. Dichas percepciones se comparan mediante un análisis de la varianza. Los resultados muestran una situación de mayor rivalidad percibida en la región española.......Most studies in agrofood industry have a macroeconomic approach. Investigations with a strategic management focus are lacking. The present paper compares the agrofood industry of two interior European regions: Castille-La Mancha and Beira Interior. This comparison is based on Porter’s (1982) Model of Competitive Forces and on the analysis of managers’ perceptions of their environment. Through deep interviews carried out to 20 managers of agrofood firms in both regions, we obteined their vision about the influence of competitive forces on industry structure. Those perceptions are compared through analysis of variance. Results show that perceived rivalry is stronger in the Spanish region.

description: The spectroscopic and spectropolarimetric variability of the peculiar variable V838 Monocerotis during the brighter phases of its multiple outbursts in 2002 is presented. Significant line profile variability of H$α$ and Si II 6347.10Å& 6371.36Åoccurred in spectra obtained between 2002 February 5 and 2002 March 14, and a unique secondary absorption component was observed near the end of this time period. Our observations also suggest that multiple shifts in ionization states occurred during the outbursts. Spectropolarimetric observations reveal that V838 Mon exhibited both intrinsic and interstellar polarization components during the initial stages of the second outburst, indicating the presence of an asymmetric geometry; however, the intrinsic component had significantly declined by February 14. We determine the interstellar polarization to be $P_{max} = 2.746 \pm 0.011 %$, $λ_{max} = 5790 \pm 37Å$, $PA = 153.43 \pm 0.12 ^{\circ} $, and we find the integrated intrinsic V band polarization on February 5 to be $P = 0.983 \pm 0.012 %$ at a position angle of $127.0 \pm 0.5^{\circ}$. The implications of these observations for the nature of V838 Monocerotis, its distance, and its ejecta are discussed.

En primer lugar, en comparación con el panorama de los países del Norte de la Unión Europea, se pone de manifiesto, como diferenciadora, la diversidad de formas de articulación de las explotaciones y de las familias agrícolas a los sistemas social y económico. A continuación, se presenta la historia reciente y la situación actual de los asalariados agrícolas, en especial en las regiones (Andalucía y Alentejo) donde tiene mayor presencia. En el último epígrafe, se debaten algunos de los ejes a destacar en un desarrollo agrícola y rural que no ignore las características propias del Sur de Europa........In this article two inner aspects from Southern Europe’s agriculture are analyzed. First, the diversity of connection forms between farms, farmer’s families and social economical systems is emphasized and differentiates two settings when compared with the environment in the northern countries from European Union. Afterwards, the recent history and current situation of agricultural laborers is presented, in particular in those regions (Andaluzia and Alentejo) were they have more attendance. Concerning the former subject, some important axels in a possible agricultural and rural development that does not ignore the unique characteristics of Southern Europe are debated.

description: We combine $^{57}$Fe Mössbauer spectroscopy and $^{57}$Fe nuclear resonant inelastic x-ray scattering (NRIXS) in nanoscale polycrystalline [bcc-$^{57}$Fe/MgO] multilayers with various Fe layer thicknesses and layer-resolved density-functional-theory (DFT) based first-principles calculations of a (001)-oriented [Fe(8 ML)/MgO(8 ML)](001) heterostructure to unravel the interface-related atomic vibrational properties of a multilayer system. In theory and experiment, we observe consistently enhanced hyperfine magnetic fields compared to bulk which are associated with the Fe/MgO interface layers. NRIXS and DFT both reveal a strong reduction of the longitudinal acoustic (LA) phonon peak in combination with an enhancement of the low-energy vibrational density of states (VDOS) suggesting that the presence of interfaces and the associated increase in the layer-resolved magnetic moments results in drastic changes in the Fe-partial VDOS. From the experimental and calculated VDOS, vibrational thermodynamic properties have been determined as a function of Fe thickness and are found to be in excellent agreement.

description: We consider m two-dimensional semi-infinite planes of Ising spins joined together through surface spins and study the critical behaviour near to the junction. The m=0 limit of the model - according to the replica trick - corresponds to the semi-infinite Ising model in the presence of a random surface field (RSFI). Using conformal mapping, second-order perturbation expansion around the weakly- and strongly-coupled planes limits and differential renormalization group, we show that the surface critical behaviour of the RSFI model is described by Ising critical exponents with logarithmic corrections to scaling, while at multiple junctions (m>2) the transition is first order. There is a spontaneous junction magnetization at the bulk critical point.

description: The SARS-CoV-2 (COVID-19) pandemic has drastically altered day-to-day life for almost everyone on the planet. Society can better prepare to slow the rate of transmission with increased knowledge about how this disease will continue to spread. This thesis aims to find a stochastic epidemiological model that accurately predicts the spread of COVID-19 in Travis County, Texas. Using the infectivity of COVID-19 and accounting for preventative measures, it was found that the spread is accurately modeled by a compartmental model known as an SIR model. The model compartmentalizes the population into three different categories - Susceptible, Infected, Removed - and then predicts the rate of transfer between the categories. This model allows us to predict the number of people susceptible to and infected with a contagious illness over time. With an accurate model of how COVID-19 transmits, we can better predict the spread to prepare and equip healthcare facilities with the appropriate materials to treat COVID-19 patients.

description: En este artículo, sus autores analizan los Condominios Agrarios como una forma asociativa adaptada a las características de la agricultura familiar en el estado brasileño de Santa Catarina. En primer lugar, analizan el proceso de modernización de la agricultura brasileña que tuvo lugar en los años 60 y 70 bajo los gobiernos militares, prestando atención a sus efectos selectivos y excluyentes sobre los pequeños agricultores. En el marco de dicho proceso, estudian, en segundo lugar, el desarrollo del cooperativismo y muestran la consolidación de un modelo de megacooperativas que refleja los intereses y características de la agricultura modernizada y orientada a la exportación. En el tercer apartado, analizan el contexto de génesis y desarrollo de los Condominios Agrraios como forma alternativa al modelo de las megacooperativas y los sitúan en el contexto de la agricultura de Santa Catarina. Finalmente, los autores reflexionan sobre este modelo de asociacionismo adaptado a las características de las pequeñas explotaciones, relacionándolo con las tesis planteadas por Chayanov sobre la agricultura familiar........In this paper, the authors analyze the Condominios as economic associations adapted to the characteristics of family agriculture in the Brazilian state of Santa Catarina. Firstly, they analyze the process of modernization of Brazilian agriculture that took place in the 1960s and 1970s under the military governments, giving special attention to the selective and exclusive effects this process had on small farmers. Within the framework of this process, they then go on to study the development of co-operativism and demonstrate how the consolidation of macro-cooperative models reflected the interests and characteristics of modernized, export-oriented agriculture. Thirdly, they analyze the origins and development of Condominios as an alternative to the large agricultural cooperatives in the Brazilian state of Santa Catarina. Finally, the authors discuss these models of association, which are adapted to the characteristics of small farms and place them in the context of the old Chayanov’s views on the family agriculture and the peasantry.

description: Production of morphology-controlled cement foams remains challenging, mainly due to bubble stability issues during cement setting. The use of cement paste with high yield stress is expected to promote stability by damping intrinsic bubble kinetics. Here we show however that for given W/C ratio, fresh foam stability can be achieved instead by decreasing the yield stress of the cement paste. Indeed, in this low apparent yield stress regime, van der Waals attraction between cement grains is reduced and grains are allowed to be efficiently packed by bubbles, providing enhanced mechanical properties. This result is obtained for two distinct additives used at controlled concentrations and without resorting to set accelerators, which highlights the general significance of the underlying stability mechanism. It offers a promising solution to produce stable cement foams at high air content.

description: The Carrington event is considered to be one of the most extreme space weather events in observational history within a series of magnetic storms caused by extreme interplanetary coronal mass ejections (ICMEs) from a large and complex active region (AR) emerged on the solar disk. In this article, we study the temporal and spatial evolutions of the source sunspot active region and visual aurorae, and compare this storm with other extreme space weather events on the basis of their spatial evolution. Sunspot drawings by Schwabe, Secchi, and Carrington describe the position and morphology of the source AR at that time. Visual auroral reports from the Russian Empire, Iberia, Ireland, Oceania, and Japan fill the spatial gap of auroral visibility and revise the time series of auroral visibility in mid to low magnetic latitudes (MLATs). The reconstructed time series is compared with magnetic measurements and shows the correspondence between low to mid latitude aurorae and the phase of magnetic storms. The spatial evolution of the auroral oval is compared with those of other extreme space weather events in 1872, 1909, 1921, and 1989 as well as their storm intensity, and contextualizes the Carrington event, as one of the most extreme space weather events, but likely not unique.

description: Context. Obscuration events caused by outflowing clumps or streams of high column density, low ionisation gas, heavily absorbing the X-ray continuum, have been witnessed in a number of Seyfert galaxies. Aims. We report on the X-ray spectral-timing analysis of the December 2016 obscuration event in NGC 3783, aimed at probing variability of the X-ray obscurer on the shortest possible timescales. The main goals of this study are to obtain independent constraints on the density, and ultimately on the distance of the obscuring gas, as well as to characterise the impact of variable obscuration on the observed X-ray spectral-timing characteristics of Seyfert galaxies. Methods. We carried out a comparative analysis of NGC 3783 during unobscured (using archival 2000-2001 XMM-Newton data) and obscured states (using XMM-Newton and NuSTAR data from the 2016 observational campaign). The timescales analysed range between ten hours and about one hour. This study was then generalized to discuss the signatures of variable obscuration in the X-ray spectral-timing characteristics of Seyfert galaxies as a function of the physical properties of the obscuring gas. Results. The X-ray obscurer in NGC 3783 is found to vary on timescales between about one hour to ten hours. This variability is incoherent with the variations of the X-ray continuum. A fast response (on timescales shorter than about 1.5 ks) of the ionisation state of the obscuring gas to the short timescale variability of the primary X-ray continuum provides a satisfactory interpretation of all the observed X-ray spectral-timing properties. This study enabled us to put independent constraints on the density and location of the obscuring gas. We found the gas to have a density of $n_{e}> 7.1 \times 10^7 \rm{cm^{-3}}$, consistent with being part of the broad line region.

description: We investigate fluxbrane solutions to the Einstein-antisymmetric form-dilaton theory in arbitrary space-time dimensions for a transverse space of cylindrical topology $S^k\times R^n$, corresponding to smeared and unsmeared solutions. A master equation for a single metric function is derived. This is a non-linear second-order ordinary differential equation admitting an analytic solution, singular at the origin, which serves as an attractor for globally regular solutions, whose existence is demonstrated numerically. For all fluxbranes of different levels of smearing the metric function diverges at infinity as the same power of the radial coordinate except for the maximally smeared case, where a global solution is known in closed form and can be obtained algebraically using U-duality. The particular cases of F6 and F3 fluxbranes in D=11 supergravity and fluxbranes in IIA, IIB supergravities are discussed.

description: Magnetic domain walls are information tokens in both logic and memory devices, and hold particular interest in applications such as neuromorphic accelerators that combine logic in memory. Here, we show that devices based on the electrical manipulation of magnetic domain walls are capable of implementing linear, as well as programmable nonlinear, functions. Unlike other approaches, domain-wall-based devices are ideal for application to both synaptic weight generators and thresholding in deep neural networks. Prototype micrometer-size devices operate with 8 ns current pulses and the energy consumption required for weight modulation is < 16 pJ. Both speed and energy consumption compare favorably to other synaptic nonvolatile devices, with the expected energy dissipation for scaled 20 nm devices close to that of biological neurons.

description: A five-coordinate monomeric Cu(II) complex, 2([Cu(hydeten)2]·smz2)·na·5H2O (Hsmz: sulfamethazine, hydeten: N-(2-hydroxyethyl)-ethylenediamine and na; nicotinamide), has been synthesized and characterized by elemental analysis, X-ray diffraction techniques, IR, EPR and UV-vis spectroscopies. In the X-ray structural analysis, the copper atom is coordinated to two hydeten ligands, one of which is a triple and the other is a bilateral. Thus, it has two five-coordinate copper central cations which exhibit a distorted square-pyramidal geometry (τ = 0.23). The charge equivalence of the molecule is provided by the four sulfamethazine ligands which are deprotonated. The powder EPR spectra of the Cu(II) complex at room temperature and in liquid nitrogen were recorded. Based on EPR and optical absorption studies, spin-Hamiltonian and bonding parameters have been calculated and indicated the presence of the unpaired electron in the dx2-y2 orbital. Antimicrobial activity studies of the synthesized compound were investigated against S. aureus, B. subtilis, P. aeruginosa, E. coli, C. albicans and A. flavus by using the microdilution method.

description: Se trata de evaluar desde una perspectiva regional las dimensiones y consecuencias que sobre el sector agrario tuvo el boom exportador de vino común acaecido en España durante la segunda mitad del siglo XIX. A tal fin, se reconstruye la evolución de los precios del caldo y se pone en relación con los cambios en los mercados y formas de comercialización. Se realiza una aproximación a lo que supuso en cuanto a la movilización de los tres factores productivos (más tierra y capital que trabajo) y se identifican como principales protagonistas a sectores sociales de medianos, y en menor medida grandes, propietarios y cosecheros. El boom provocó además algunas sintomáticas novedades: una incipiente especialización de funciones entre productores de uva y fabricantes de vino, una articulación de intereses empresariales en la Asociación Vinícola de Navarra y una dinámica de búsqueda de mercados traducida en la participación en exposiciones nacionales e internacionales.......In a regional perspective, this article values the extent and the consequences of the exporter boom of table wine during the second half of the XIX century. So, the price data are reconstructed and the changes in the navarrese wine markets are examined. From the supply’s prospect, the viticultural specialization mobilized more land and capital than workforce, and the main protagonist was a social group of middling landowners and vintagers. The boom brought some expressive changes: a growing dissociation between grape producer and wine manufacturer, a joint of bussiness interests under the Asociación Vinícola de Navarra, and the search of new markets through the presence in domestic and international exhibitions.
