description: El mercado de la sidra natural en Asturias ha alcanzado en los últimos años los niveles máximos de saturación. Esto exige por parte de los fabricantes el abandono de las prácticas habituales de producción, en favor de criterios más eficientes de gestión. Un buen ejemplo de ello es la reciente adopción del etiquetado, práctica ampliamente debatida y criticada con anterioridad a su entrada en vigor, o la próxima implantación de la Denominación de Origen. El objetivo de este trabajo es descubrir las principales amenazas y oportunidades del sector que condicionan el lanzamiento del producto al exterior, comparando estos problemas con los que se aprecian en el caso de la sidra gasificada, que tradicionalmente ha tenido siempre una mayor proyección hacia el mercado internacional. Para ello, se llevaron a cabo una serie de visitas y entrevistas personales a una amplia muestra de fabricantes en el mercado de la sidra, a fin de disponer de un conocimiento lo más completo posible de la situación actual y llegar a predecir las tendencias futuras, de manera que los fabricantes cuenten con unas pautas de actuación para pasar a operar con eficiencia en mercados cada vez más globalizados......The market of natural cider in Asturias has got saturated in the last few years. That makes manufacturers to consider abandoning the traditional way of elaborating the cider and choosing more effective models for managing the business. A good example of this is the recently introduced practice of labelling the bottles, very discussed before its final application, and the forthcoming denomination of origin. The objective of this work is discovering the main opportunities and problems in the sector, which hardly condition the launch of the product to the international commerce. The problems will be compared to those in the gasified sector, which has always been more focused to external markets. For getting this purpose, some interviews were arranged with a wide sample of manufacturers in the cider sector in order to have a profound knowledge about the current situation of the sector and so, to be able to give some advises for manufacturers in the future.

description: We have calculated inverse-Compton Doppler factors for 3C 279 using the collection of VLBI data recently published by us, and the collection of multiwavelength spectra recently published by Hartman et al. From the Doppler factor and superluminal apparent speed, we then calculate the Lorentz factor and angle to the line-of-sight of the parsec-scale relativistic jet. We model the jet components as homogeneous spheres and the VLBI core as an unresolved inhomogeneous conical jet. The conical-jet model can be made to match both the observed X-ray emission and the VLBI properties of the core with a suitable choice of Doppler factor, implying the core makes a significant contribution to the X-ray emission. The parameters of the conical models indicate the jet is particle dominated at the radii that produce significant emission, and is not in equipartition. At the inner radius of the conical jet the magnetic field is of order 0.1 G and the relativistic-particle number density is of order 10 cm^{-3}. When all components are included in the calculation, then on average the core produces about half of the X-rays, with the other half being split between the long-lived component C4 and the brightest inner-jet component. We calculate an average speed and angle to the line-of-sight for the region of the jet interior to 1 mas of v=0.992c (gamma=8) and 4 degrees, and an average speed and angle to the line-of-sight for C4 (at a distance from the core of 3 mas) of v=0.997c (gamma=13) and 2 degrees. These values imply average Doppler factors of delta=12 for the inner jet, and delta=21 for C4.

description: This paper deals with distinct computational methods to enumerate the set $\mathrm{PLR}(r,s,n;m)$ of $r \times s$ partial Latin rectangles on $n$ symbols with $m$ non-empty cells. For fixed $r$, $s$, and $n$, we prove that the size of this set is a symmetric polynomial of degree $3m$, and we determine the leading terms (the monomials of degree $3m$ through $3m-9$) using inclusion-exclusion. For $m \leq 13$, exact formulas for these symmetric polynomials are determined using a chromatic polynomial method. Adapting Sade's method for enumerating Latin squares, we compute the exact size of $\mathrm{PLR}(r,s,n;m)$, for all $r \leq s \leq n \leq 7$, and all $r \leq s \leq 6$ when $n=8$. Using an algebraic geometry method together with Burnside's Lemma, we enumerate isomorphism, isotopism, and main classes when $r \leq s \leq n \leq 6$. Numerical results have been cross-checked where possible.

description: La pesca marítima ha constituido tradicionalmente un capítulo de especial relevancia en las relaciones entre España y Marruecos. Los acuerdos pesqueros han sido utilizados tradicionalmente por Marruecos para obtener mayores compensaciones de toda índole (financieras, comerciales,...). Este hecho, unido al continuo recorte de las posibilidades de pesca y a las crecientes exigencias en cuanto a medidas de control, descanso biológico, desembarco de capturas, etc., ha desembocado en la no renovación del último acuerdo de 1995 y el desastre económico para el sector pesquero español, muy dependiente del banco canariosahariano. El objetivo de este trabajo es realizar un análisis histórico de los acuerdos de pesca con Marruecos, que contribuya a la comprensión de la delicada situación actual, cuya solución radica en la reconversión del sector, la firma de nuevos acuerdos y la creación de empresas conjuntas, fundamentales para mantener la tradicional actividad de la flota española en el caladero alauita......Sea fishing has traditionally been a very important matter in the relationship between Spain and Morocco. Morocco has used fishing agreements in order to obtain higher counterweights in several orders (financial, commercial...). This fact, joined to the continuous decrease in fishing opportunities, and to the increasing requirents on control measures, biological rest, landing of captures, etc..., has resulted in the no renewal of the last 1995 agreement, and in the economic disaster for the Spanish fishing sector, which is highly dependent from the Canary Island and Sahara shoal. The aim of this work is to make a historical analysis of the sea fishing agreements between Spain and Morocco, ´that help us to understand better the present situation, wich solution relies on the reconversion of this sector, new agreements, and mixed firms. These are very important factors to maintain the traditional Spanish activity in Moroccan shoal.

description: Electronic transport at finite voltages in free-standing gold atomic chains of up to 7 atoms in length is studied at low temperatures using a scanning tunneling microscope (STM). The conductance vs voltage curves show that transport in these single-mode ballistic atomic wires is non-dissipative up to a finite voltage threshold of the order of several mV. The onset of dissipation and resistance within the wire corresponds to the excitation of the atomic vibrations by the electrons traversing the wire and is very sensitive to strain.

description: Given a topological space X denote by exp_k(X) the space of non-empty subsets of X of size at most k, topologised as a quotient of X^k. This space may be regarded as a union over 0 < l < k+1 of configuration spaces of l distinct unordered points in X. In the special case X=S^1 we show that: (1) exp_k(S^1) has the homotopy type of an odd dimensional sphere of dimension k or k-1; (2) the natural inclusion of exp_{2k-1}(S^1) h.e. S^{2k-1} into exp_2k(S^1) h.e. S^{2k-1} is multiplication by two on homology; (3) the complement exp_k(S^1)-exp_{k-2}(S^1) of the codimension two strata in exp_k(S^1) has the homotopy type of a (k-1,k)-torus knot complement; and (4) the degree of an induced map exp_k(f): exp_k(S^1)-->exp_k(S^1) is (deg f)^[(k+1)/2] for f: S^1-->S^1. The first three results generalise known facts that exp_2(S^1) is a Moebius strip with boundary exp_1(S^1), and that exp_3(S^1) is the three-sphere with exp_1(S^1) inside it forming a trefoil knot.

description: We give an overview of the current understanding of Type Ia supernovae relevant for their use as cosmological distance indicators. We present the physical basis to understand their homogeneity of the observed light curves and spectra and the observed correlations. This provides a robust method to determine the Hubble constant, 67 +- 8 (2 sigma) km/Mpc/sec, independently from primary distance indicators. We discuss the uncertainties and tests which include SNe Ia based distance determinations prior to delta-Ceph. measurements for the host galaxies. Based on detailed models, we study the small variations from homogeneities and their observable consequences. In combination with future data, this underlines the suitability and promises the refinements needed to determine accurate relative distances within 2 to 3 % and to use SNe Ia for high precision cosmology.

Two-Component Fluid Membranes Near Repulsive Walls: Linearized Hydrodynamics of Equilibrium and Non-equilibrium States

description: We study the linearized hydrodynamics of a two-component fluid membrane near a repulsive wall, via a model which incorporates curvature- concentration coupling as well as hydrodynamic interactions. This model is a simplified version of a recently proposed one [J.-B. Manneville et al. Phys. Rev. E, 64, 021908 (2001)] for non-equilibrium force-centres embedded in fluid membranes, such as light-activated bacteriorhodopsin pumps incorporated in phospholipid (EPC) bilayers. The pump/membrane system is modeled as an impermeable, two-component bilayer fluid membrane in the presence of an ambient solvent, in which one component, representing active pumps, is described in terms of force dipoles displaced with respect to the bilayer midpoint. We first discuss the case in which such pumps are rendered inactive, computing the mode structure in the bulk as well as the modification of hydrodynamic properties by the presence of a nearby wall. We then discuss the fluctuations and mode structure in steady state of active two-component membranes near a repulsive wall. We find that proximity to the wall smoothens membrane height fluctuations in the stable regime, resulting in a logarithmic scaling of the roughness even for initially tensionless membranes. This explicitly non-equilibrium result, a consequence of the incorporation of curvature-concentration coupling in our treatment, also indicates that earlier scaling arguments which obtained an increase in the roughness of active membranes near repulsive walls may need to be reevaluated.

description: Photon pairs and heralded single photons, obtained from cavity-assisted parametric down-conversion (PDC), play an important role in quantum communications and technology. This motivated a thorough study of the spectral and temporal properties of parametric light, both above the Optical Parametric Oscillator (OPO) threshold, where the semiclassical approach is justified, and deeply below it, where the linear cavity approximation is applicable. The pursuit of a higher two-photon emission rate leads into an interesting intermediate regime where the OPO still operates considerably below the threshold but the nonlinear cavity phenomena cannot be neglected anymore. Here, we investigate this intermediate regime and show that the spectral and temporal properties of the photon pairs, as well as their emission rate, may significantly differ from the widely accepted linear model. The observed phenomena include frequency pulling and broadening in the temporal correlation for the down-converted optical fields. These factors need to be taken into account when devising practical applications of the high-rate cavity-assisted SPDC sources.

description: The electronic structure, specific heat, and thermal conductivity of silicon embedded in a monolayer graphene nanosheet are studied using Density Functional Theory. Two different shapes of the substitutional Si doping in the graphene are studied, a triangular and a dot shape. The silicon doping of a graphene nanosheet, with the silicon atoms arranged in a triangular configuration in ortho- and para-positions, opens up a band gap transforming the sheet to a semiconducting material. The opening of the band gap is caused by the presence of the repulsion force between the silicon and carbon atoms decreasing the density of states around the Fermi energy. Consequently, the specific heat and the thermal conductivity of the system are suppressed. For graphene nanosheet doped with a dot-like configuration of silicon atoms, at the ortho-, meta-, and para-positions, the valence band crosses the Fermi level. This doping configuration increases the density of state at the Fermi level, but mobile charge are delocalized and diminished around the silicon atoms. As a result, the specific heat and the thermal conductivity are enhanced. Silicon substitutionally doped graphene nanosheets may be beneficial for photovoltaics and can further improve solar cell devices by controlling the geometrical configuration of the underlying atomic systems.

description: Introduction: It’s been 20 years since the first report of a recombinant vaccine that protected against leptospirosis. Since then, numerous recombinant vaccines have been evaluated; however, no recombinant vaccine candidate has advanced to clinical trials. With the ever-increasing burden of leptospirosis, there is an urgent need for a universal vaccine against leptospirosis. Areas covered: This review covers the most promising vaccine candidates that induced significant, reproducible, protection and how advances in the field of bioinformatics has led to the discovery of hundreds of novel protein targets. The authors also discuss the most recent findings regarding the innate immune response and host–pathogen interactions and their impact on the discovery of novel vaccine candidates. In addition, the authors have identified what they believe are the most challenging problems for the discovery and development of a universal vaccine and their potential solutions. Expert opinion: A universal vaccine for leptospirosis will likely only be achieved using a recombinant vaccine as the bacterins are of limited use due to the lack of a cross-protective immune response. Although there are hundreds of novel targets, due to the lack of immune correlates and the need for more research into the basic microbiology of Leptospira spp., a universal vaccine is 10–15 years away.

description: We study ferromagnetic transition in three-dimensional double-exchange model containing impurities. The influence of both spin fluctuations and impurity potential on conduction electrons is described in coherent potential approximation. In the framework of thermodynamic approach we construct Landau functional for the system "electrons (in disordered environment) + core spins". Analyzing the Landau functional we calculate the temperature of ferromagnetic transition $T_C$ and paramagnetic susceptibility $χ$. For $T_C$, we thus extend the result obtained by Furukawa in the framework of the Dynamical Mean Field Approximation, with which our result coincides in the limit of zero impurity potential. We find, that the alloy disorder, able to produce a gap in density of electron states, can substantially decrease $T_C$ with respect to the case of no impurities. We also study the general relation between the Coherent Potential Approximation and the Dynamical Mean Field Approximation.

description: Nowadays the world is witnessing increased applications and development of LED’s. In purchasing a new TV it occurred to me that LEDs are the leading technology in the market; perhaps one has heard of QLED (Quantum dot LED) TVs and as of recent OLED (Organic LED) TVs, which as their names signify are both made special due to their perplexing LED technologies. Fundamentally speaking; LEDs or light emitting diodes are semiconductor devices that emit light of singular wavelengths upon flow of current. Having grown fascinated by LEDs’ ability to emit light of virtually any wavelength (spanning the entirety of the visible spectrum: 400 ~ 700nm) (Banerjee & Chattopadhyay, 2018) I speculated if each discrete wavelength emitting LED possessed a unique set of IV characteristics. Eager to explore the workings of LEDs I stumbled upon the Shockley diode equation; an equation invented by the celebrated American physicist and inventor William Shockley which relates current to applied forward bias for a semiconductor diode (Jones, 2014); this led to my research question “How accurately can the Shockley diode equation be used to model the current-voltage characteristics of singular wavelength LEDs (400-700nm)?”.

description: We consider singular perturbed eigenvalue problem for Laplace operator in a two-dimensional domain. In the boundary we select a set depending on a character small parameter and consisting of a great number of small disjoint parts. On this set the Dirichlet boundary condition is imposed while on the rest part of the boundary we impose the Neumann condition. For the case of homogenized Neumann or Robin boundary value problem we obtain highly weak restrictions for distribution and lengths of boundary Dirichlet parts of the boundary under those we manage to get the leading terms of asymptotics expansions for perturbed eigenelements. We provide explicit formulae for these terms. Under weaker assumptions we estimate the degrees of convergence for perturbed eigenvalues.

description: Simulations of cold dark matter make robust predictions about the slope and normalization of the dark matter halo and subhalo mass functions on small scales. Recent observational advances utilizing strong gravitational lensing have demonstrated the ability of this technique to place constraints on these quantities on subgalactic scales corresponding to dark matter halo masses of $10^6$--$10^9\mathrm{M}_\odot$. On these scales the physics of baryons, which make up around 17% of the matter content of the Universe but which are not included in pure dark matter N-body simulations, are expected to affect the growth of structure and the collapse of dark matter halos. In this work we develop a semi-analytic model to predict the amplitude and slope of the dark matter halo and subhalo mass functions on subgalactic scales in the presence of baryons. We find that the halo mass function is suppressed by up to 25%, and the slope is modified, ranging from $-1.916$ to $-1.868$ in this mass range. These results are consistent with current measurements, but differ sufficiently from the expectations for a dark matter only universe that it may be testable in the near future.

description: Since rural drinking water projects have diversified investment subjects, complex form, and lacks property right system and policy at national level, there are many difficulties in determining property right of projects in many areas. This not only puzzles competent authorities and specific management institution, but also is unfavorable for long-term full play of project benefit. Combining related laws, regulations, and policies, this paper analyzed and discussed property right of rural drinking water projects. It proposed establishing usufructuary right to replace division of property right, in the hope of helping improve management of rural drinking water projects.

Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions.

Evanescent Waves and Superluminal Behavior of Matter

description: An evanescent wave is a non-propagating wave with an imaginary wave vector. In this study, we prove that these are solutions of the tachyon-like Klein Gordon equation, and that in the tunneling of ultrarelativistic half integer spin particles they describe superluminal states arising from interactions between a particle and barrier. These states decay as a particle emerges from the opposite side of a potential barrier, conserving the same initial energy but not necessarily the same mass. The obtained theory is applied to the neutrino, to explain flavor oscillations during free flight and determine the conditions that maximize the probability of their occurrence.

description: We present a model of the circumstellar environment of the so-called ``Butterfly Star'' in Taurus (IRAS 04302+2247). The appearance of this young stellar object is dominated by a large circumstellar disk seen edge-on and the light scattering lobes above the disk. The model is based on multi-wavelength continuum observations: Millimeter maps and high-resolution near-infrared images obtained with HST/NICMOS. It was found that the disk and envelope parameters are comparable with those of the circumstellar environment of other young stellar objects. A main result is that the dust properties must be different in the circumstellar disk and in the envelope: While a grain size distribution with grain radii up to 100 micron is required to reproduce the millimeter observations of the disk, the envelope is dominated by smaller grains similar to those of the interstellar medium.

From classical to quantum spintronics: Theory of coherent spin injection and spin valve phenomena

description: We present a theory of coherent quantum transport in ferromagnetic/ non-magnetic/ ferromagnetic heterojunctions. We predict quantum coherence to give rise to a quantum spin valve effect that, unlike its familiar classical analog, occurs even in the absence of a net spin current through the heterostructure. Thus the relationship between spin and charge transport is qualitatively different in the presence of quantum interference than in the (semi)classical regime. This has important implications for the design of quantum coherent spintronic devices and the interpretation of experiments.

description: Abstract

The decision-making processes and the factors influencing the decision that finally leads businesses to the acquisition of real estate in Uganda is at the heart of most feasibility appraisals targeting high-performing real estate portfolios. Yet, over time, we see an increasing sophistication of real estate investments decision-making as strategy formulation, analysis and decision-making in entrepreneurial settings continue to be problematic in the face of business challenges such as lack of real estate investment knowledge and skills, limited resources to finance real estate investments, inadequate availability of serviced land for development and the absence of reliable market data creating a lot of market uncertainty in-turn affecting the decision-making processes and quality of decisions. This paper reviews literature with a view of identifying the challenges to real estate decision making as well as finding the existence and use of decision theory and decision support systems therein for businesses in Uganda while navigating these challenges. The findings of the research, from the analysis of the descriptions, confirms that there is lack of credible economic and market data in practice as regards real estate operations in Uganda as well as a lack of real estate investment knowledge and skills by businesses which creates challenges for well informed decision making. It is also evident that the decision processes are usually subjective and depend, to a great extent, on the experience of the decision-maker and their intuition. Biases and heuristics are evident in these decisions. The research has based itself on analysing the extent of application of both descriptive and normative decision models lending detail to the Utility approach for decision making of businesses investing in real estate under market uncertainty as regards the real estate practice in Uganda. We conclude by proposing the development of a real estate investment framework for business in Uganda that will provide a package of implementable solutions as a plausible approach to addressing the challenge.

description: In a series of papers we have found statistically significant correlations between arrival directions of ultra-high energy cosmic rays and BL Lacertae objects. Recently, our calculations were partly repeated by Evans, Ferrer and Sarkar with different conclusions. We demonstrate that the criticism of Evans, Ferrer and Sarkar is incorrect. We also present the details of our method.

description: Russia is often considered the most prominent country to become a leader on the world grain market. However, several issues slow down Russia’s agricultural progress, for example: a lack of infrastructure and investments, unequal regional development, and inefficient use of production technologies. This study therefore examines the grain production potential of Russian regions by employing a modified approach to stochastic frontier analysis that allows us to include not only production technologies, but also indicators of country’s heterogeneity and diversity among regions. Obtained results indicate that climate conditions in combination with the level of human and institutional development, and infrastructure have significant effect on the production structure of regions and therefore should not be neglected while assessing regional policies and production potential.
Transmission Probability for Interacting Electrons Connected to Reservoirs

description: Transport through small interacting systems connected to noninteracting leads is studied based on the Kubo formalism using a Eliashberg theory of the analytic properties of the vertex part. The transmission probability, by which the conductance is expressed as $g = (2e^2/h) \int dε (- \partial f / \partial ε) {\cal T}(ε)$, is introduced for interacting electrons. Here $f(ε)$ is the Fermi function, and the transmission probability ${\cal T}(ε)$ is defined in terms of a current vertex or a three-point correlation function. We apply this formulation to a series of Anderson impurities of size N (=1,2,3,4), and calculate ${\cal T}(ε)$ using the order $U^2$ self-energy and current vertex which satisfy a generalized Ward identity. The results show that ${\cal T}(ε)$ has much information about the excitation spectrum: ${\cal T}(ε)$ has two broad peaks of the upper and lower Hubbard bands in addition to N resonant peaks which have direct correspondence with the noninteracting spectrum. The peak structures disappear at high temperatures.

description: Using the revised Komar-Tomimatsu approach, we derive Smarr mass formulas for stationary axisymmetric solutions of the Einstein-Maxwell equations containing line singularities (defects) on the polar axis. In terms of the rod structure associated with Weyl representation of the metric, the horizons and the defects are formally similar up to differences due to their timelike/spacelike character. We derive (previously unknown or incorrect) horizon and global Smarr formulas in presence of a Newman-Unti-Tamburino (NUT) parameter. To avoid the divergence of the Komar angular momentum of semi-infinite Dirac and Misner strings, it is necessary to use a symmetric tuning. We also note that the horizon mass Smarr formula does not include either magnetic charge, or NUT parameter, correcting some statements in the literature. The contribution of each Misner string to the total mass consists in an angular momentum term, an electric charge term, and a length term, which can also be presented as the product of the spacelike analogue of surface gravity and the area of the string.

description: We investigate by Monte Carlo simulations the critical properties of the three-dimensional bond-diluted Ising model. The phase diagram is determined by locating the maxima of the magnetic susceptibility and is compared to mean-field and effective-medium approximations. The calculation of the size-dependent effective critical exponents shows the competition between the different fixed points of the model as a function of the bond dilution.
