description: RESUMEN - Desde que recientemente se ha reparado en los ecosistemas forestales como posibles sumideros del CO2 atmosférico, se ha propuesto el establecimiento de masas forestales como medida para reducir las concentraciones de este gas. Esto llevaría a que las plantaciones forestales presentaran objetivos adicionales de carácter ambiental. Bajo la óptica de un propietario privado o un posible inversor en esta clase de activos forestales, estas circunstancias sitúan al centro decisor ante un problema de producción conjunta, diferente al que existía hasta hace poco tiempo. Por otro lado, desde un punto de vista social interesará que la captura de carbono sea máxima. Se han estudiado dos posibles casos de forestaciones, y los resultados muestran que el sistema actual de ayudas puede constituir una solución subóptima, ya que añadir nuevas subvenciones a las ya existentes no va a provocar una mayor captura de carbono, sino únicamente incrementar los ingresos de los propietarios. SUMMARY - Since recently forest ecosystems has been included as possible sinks of the atmospheric CO2, the establishment of new forest plantations is mentioned as a measure to mitigate the concentrations of this gas. This capacity would take to assess environmental objectives into afforestations programs. Under the optics of a private landowner or a possible investor in this kind of assets, these circumstances turn decision-making process into a joint production case, different to the traditional management of these forestations. On the other hand, from a social point of view the capture of carbon would be at his maximum. Two possible cases of afforestations have been discussed, and the results show that the current system of European grants cannot constitute an optimal solution, since to add new grants to those existent it won't cause bigger carbon storage, but only an increase in the landowners' revenues.

description: We examined X-ray spectral and timing properties of ultraluminous X-ray sources (ULXs) in nearby galaxies in XMM-Newton archival data. There appear to be three distinct classes of spectra. One class shows emission from hot, diffuse plasma. This thermal emission is similar to that seen from recent supernovae; the temperatures are in the range 0.6-0.8 keV and the luminosities are the lowest in our sample, near 10^39 erg/s. Three sources have spectra which are strongly curved at high energies and have the highest temperatures in our sample, 1.0-1.4 keV. These spectra are well fitted with a power-law plus multicolor disk blackbody model with the power-law dominant at low energies or a Comptonization model. The remainder of the sources are best fitted with a power-law plus multicolor disk blackbody model, as is commonly used to describe the spectra of accreting black holes. These sources have the lowest thermal component temperatures, 0.1-0.4 keV, and extend to the highest luminosities, above 10^40 erg/s. The temperature of the thermal component is in three distinct ranges for the three source classes. This diversity of spectral shapes and the fact that the sources lie in three distinct temperature ranges suggests that the ULXs are a diverse population. Two ULXs which show state transitions stay within a single class over the course of the transition. However, we cannot conclude with certainty that the classes represent distinct types of objects rather than spectral states of a single population of objects. We also searched for timing noise from the sources and report detection of noise above the Poisson level from five sources. In three of the sources, the power density spectrum increases with decreasing frequency as a power-law down to the lowest frequencies observed, below 10^-4 Hz.

description: M31 RV is a luminous red variable star that appeared for several months in the bulge of M31 during 1988. Unlike classical novae, M31 RV was cool throughout its outburst. Interest in this object has revived recently because of its strong resemblance to V838 Mon, a luminous Galactic variable star that appeared in 2002 and is illuminating a spectacular light echo, and has evolved to ever-cooler surface temperatures. V4332 Sgr is a third object which was also a red supergiant throughout its eruption. We have examined archival Hubble Space Telescope (HST) images of the site of M31 RV, obtained fortuitously in 1999 with the WFPC2 camera in parallel mode during spectroscopic observations of the nucleus of M31. We located the site of M31 RV in the HST frames precisely through astrometric registration with ground-based CCD images, including several taken during the outburst. No light echo is seen at the M31 RV site, implying that M31 RV is not surrounded by circumstellar (or interstellar) dust similar to that around V838 Mon, or that its extent is less than ~1.7 pc. The stellar population at the outburst site consists purely of old red giants; there is no young population, such as seen around V838 Mon. There are no stars of unusual color at the site, suggesting that M31 RV had faded below HST detectability in the 11 years since outburst, that it is an unresolved companion of one of the red giants in the field, or that it is one of the red giants. We suggest future observations that may help decide among these possibilities.

Painlevé V and the Hankel Determinant for a Singularly Perturbed Jacobi Weight

description: We study the Hankel determinant generated by a singularly perturbed Jacobi weight $$ w(x,t):=(1-x^2)^α\mathrm{e}^{-\frac{t}{x^{2}}},\;\;\;\;\;\;x\in[-1,1],\;\;α>0,\;\;t\geq 0. $$ If $t=0$, it is reduced to the classical symmetric Jacobi weight. For $t>0$, the factor $\mathrm{e}^{-\frac{t}{x^{2}}}$ induces an infinitely strong zero at the origin. This Hankel determinant is related to the Wigner time-delay distribution in chaotic cavities. In the finite $n$ dimensional case, we obtain two auxiliary quantities $R_n(t)$ and $r_n(t)$ by using the ladder operator approach. We show that the Hankel determinant has an integral representation in terms of $R_n(t)$, where $R_n(t)$ is closely related to a particular Painlevé V transcendent. Furthermore, we derive a second-order nonlinear differential equation and also a second-order difference equation for the logarithmic derivative of the Hankel determinant. This quantity can be expressed in terms of the Jimbo-Miwa-Okamoto $σ$-function of a particular Painlevé V. Then we consider the asymptotics of the Hankel determinant under a suitable double scaling, i.e. $n\rightarrow\infty$ and $t\rightarrow 0$ such that $s=2n^2 t$ is fixed. Based on previous results by using the Coulomb fluid method, we obtain the large $s$ and small $s$ asymptotic behaviors of the scaled Hankel determinant, including the constant term in the asymptotic expansion.

description: RESUMEN - El objetivo de este trabajo es estudiar, desde el punto de vista primal, la eficiencia técnica de una muestra de barcos dedicados a la pesca de merluza en Asturias. Un rasgo característico de esta actividad es la importancia que tienen las capturas de otras especies distintas de la merluza. La naturaleza multiproducto de esta actividad plantea distintas alternativas de modelización. En este trabajo se comparan los resultados obtenidos a partir de la estimación de una función de producción agregada, una función de producción multiproducto y una función de distancia. Los tres modelos se estiman utilizando el estimador intragrupos. En una segunda etapa, los índices de eficiencia se calculan a partir de los efectos individuales una vez eliminada la influencia de variables invariantes en el tiempo. Para la realización del estudio empírico se dispone de un panel de datos que contiene información acerca de la actividad pesquera de once embarcaciones asturianas a lo largo de 1999. SUMMARY - The objective of this paper is to study, following a primal approach, the technical efficiency of a sample of boats which catch hake in Asturias. In this activity the catches of species different from hake are important. The multiproduct nature of this activity raises different modelling alternatives. In this paper we compare the results obtained in the estimation of an aggregate production function, a multiproduct production function, and a distance function. The three models are estimated using the within-groups estimator. After eliminating the influence of time invariant variables, the efficiency indexes are calculated in a second stage using the individual fixed effects. The empirical analysis uses a panel data set of eleven boats in 1999.

description: We present atomic-scale computer simulations in equiatomic L1$_0$-CoPt where Molecular Dynamics and Monte Carlo techniques have both been applied to study the vacancy-atom exchange and kinetics relaxation. The atomic potential is determined using a Tight-Binding formalism within the Second-Moment Approximation. It is used to evaluate the different saddle-point energies involved in a vacancy-atom exchange between nearest-neighbour sites. The potential and the saddle-point energies have been used to simulate the relaxation of the long-range order in CoPt using a Monte Carlo technique. A vacancy migration energy of $0.73\pm 0.15 eV$ and an order-disorder transition temperature of 935 K have been found.

description: Resumen : El objetivo de este artículo es el estudio y generalización del método de las dos funciones de distribución, utilizado en la teoría de valoración y, más concretamente, en las valoraciones agrarias. El fundamento básico de este método, propuesto por Ballestero (1973), está en la utilización de un índice representativo del activo que pretendemos valorar y en la aceptación de una serie de hipótesis sobre la distribución de la variable índice y de la variable valor del activo. Hasta este momento y en todos los trabajos publicados sobre este método, se ha mantenido la limitación de utilizar un solo índice (aunque éste sea una síntesis de varios a los que pretende representar). En este trabajo se presenta un método que generaliza el anterior y que permite trabajar con más de un índice, de modo que sea posible determinar el valor de un activo con referencia no sólo a un índice sino a varios. El método permite trabajar con diferentes funciones de distribución de las utilizadas para tratar el riesgo y presenta un test de aceptación de las funciones utilizadas para modelar los índices. Finalmente, se desarrolla un caso práctico. Summary : The aim of this paper is the study and generalization of the method of the two distribution functions, used in the theory of valuation and, more concretely, in the agrarian valuations. The basic foundation of this method, proposed by Ballestero (1973), is the use of a representative index of the asset that we try to value and in the acceptance of a series of hypotheses on the distribution of the variable index and of the variable value of the asset. Until this moment and in all the works published on this method, the limitation of using a single index (although this is a synthesis of several to which it tries to represent) has remained. In this work it is presented a method that generalizes the previous one and that allows us to work with more than an index, so that it is possible not only to determine the value of an asset with reference to an index but to several ones. The method allows to work with different distribution functions of those used to treat the risk and it presents a test of acceptance of the functions used to model the indexes. Finally, a practical case is developed.

description: SUMMARY - This study focuses on the analysis of the production behavior and risk preferences in the presence of output price uncertainty. Following a theoretical model based on the assumption of maximization of expected utility of profits, the approach used in this study infers information about risk preferences from the production characteristics of the farm. In addition, the nonparametric method of estimating elasticity of scale and technical change eliminates the need to impose a uniform production or cost functions on individual producers. The approach is applied to a panel of dairy farms, which are evaluated for their elasticity of scale and the total productivity growth components of their operations. Estimates of farmers' risk attitudes represented by individual marginal risk premiums are also related to socio-economic attributes of farmers. Overall, farm size plays an important role in explaining productivity and scale differences and has the most significant negative effect on marginal risk aversion. The magnitude of the impact of additions to the farm's dairy herd increases with scale of operations. RESUMEN - El objetivo de este trabajo es el análisis del comportamiento de la producción y en las preferencias ante el riesgo en condiciones de incertidumbre en el precio de salida. Siguiendo un modelo teórico basado en la asunción de maximización de utilidad de los beneficios, el enfoque empleado en este trabajo permite obtener información relativa a las preferencias ante el riesgo a partir de las características de la explotación. Además, el método no-paramétrico de estimación de la elasticidad de la escala y del cambio técnico elimina la necesidad de imponer una producción uniforme o funciones de precio sobre productores particulares. Este enfoque se aplica a un panel de explotaciones lecheras, que son evaluadas en función de los componentes relativos a su elasticidad de escala y al incremento total de la productividad de sus operaciones. Las estimaciones en torno a las actitudes de los productores ante el riesgo representadas por primas individuales por riesgos marginales están igualmente relacionadas con a los atributos socioeconómicos de los productores. En conjunto, el tamaño de la explotación es importante para explicar las diferencias en productividad y escala, y produce el efecto negativo más significativo sobre la aversión al riesgo marginal. La magnitud del impacto de nuevas incorporaciones de cabezas de ganado a los rebaños en explotaciones lecheras aumenta con la escala de las operaciones.

description: RESUMEN - La reestructuración que acompaña al régimen de cuotas en España, que pudo tener un sesgo más propio, sigue en sus resultados pautas de otros países de la UE. La trayectoria del proceso es similar a la de Alemania o Francia. Sin embargo, en cuanto al patrón para la gestión de las cuotas se ha venido inclinando hacia el esquema flexible del Reino Unido y Holanda, incluso regionalizando de facto el tráfico de cuotas, pues las transacciones entre CC.AA. están sometidas a fuertes limitaciones administrativas. En España el sistema de estado ha propiciado un escenario como el francés o el alemán, pero obtenido de esa gestión liberal de las cuotas según los modelos británico y holandés. Más que la desvinculación de cuota y tierra, han jugado los intereses de las CC.AA., para las que su territorio es una circunscripción cerrada de la que no debe salir cuota para evitar las pérdidas de patrimonio lechero por la deslocalización de la producción debida a las diferencias de competitividad entre ellas. SUMMARY - The structural change linked to the quota regime has had the same results as in other EC countries. The process is similar to the one in Germany or France. However, the pattern of quota management in Spain is closer to the flexible model in United Kingdom and The Netherlands. On the other hand, the quotas are shared out de facto amongst Autonomous Regions, as quota transactions between them are subject to strong administration limits. More than the separation between quota and land, the interests of Autonomous Regions have taken part as these consider their territory as a locked district, from which no quota can be left out in order to avoid any loss in their wealth.

description: RESUMEN - En este artículo se analizan los efectos de algunas políticas de gestión del agua y de las técnicas de riego sobre el rendimiento de las actividades de cultivo y la contaminación del agua en la zona de regadío de Flumen-Monegros. El análisis se basa en la obtención de la respuesta del rendimiento de los cultivos al agua de riego y al abonado de nitrógeno. Las funciones de rendimiento se estiman mediante el programa de crecimiento de cultivos EPIC que incorpora información de las características locales de clima, suelo, manejo y sistema de riego de las actividades de cultivo. En los resultados se examina la relación entre los rendimientos y el uso del agua y del nitrógeno, y se cuantifica el coste para los agricultores de la reducción de la contaminación. El coste de reducción de la contaminación depende del cultivo y del tipo de medida aplicada, y estos costes tienen una gran importancia para el diseño y la eficiencia de las medidas de reducción de la contaminación. SUMMARY - This paper analyzes the effects of some water management policies and irrigation systems on crop yields and water pollution, in an area located in the Flumen-Monegros irrigation district in Huesca (Spain). The analysis is performed using water and nitrogen crop response functions, which are estimated with the EPIC crop growth package. The estimation of response for the crop activities incorporates information on local climate, soils, crop management and irrigation systems. The relationship between yields and water and nitrogen input use is examined, in order to quantify the pollution reduction cost faced by farmers. The costs depend on the particular crop and the pollution abatement measure, and information on these costs is important to design efficient pollution abatement measures.

description: Artificial drying of corn in the Southeastern Coastal Plain was shown to be financially feasible for average annual per farm production levels of greater than 10,000 bushels. Net present values for four types of drying systems were evaluated using simulation modeling in which weather conditions, yield levels, and prices were entered as stochastic variables. Scale of production and irrigation substantially influenced crop drying potential. Stochastic efficiency analysis was used to evaluate the riskiness of the investment.

FORWARD CONTRACTING VERSUS HEDGING UNDER PRICE AND YIELD UNCERTAINTY

Year: 1986
Subjects: Risk and Uncertainty

description: Although apparently preferred by farmers to direct hedging as a forward pricing mechanism, forward contracting has received little attention in the literature dealing with optimal forward pricing levels. An often-cited reason for producer preference for forward contracting is the absence of basis risks under that forward pricing alternative. This paper presents models of optimal forward contracting and hedging under price and yield uncertainty within a mean-variance framework. The results indicate that basis certainty does not explain preferences for forward contracting.

description: We consider the asymptotic quasinormal frequencies of various spin fields in Schwarzschild and Reissner-Nordström black holes. In the Schwarzschild case, the real part of the asymptotic frequency is ln3 for the spin 0 and the spin 2 fields, while for the spin 1/2, the spin 1, and the spin 3/2 fields it is zero. For the non-extreme charged black holes, the spin 3/2 Rarita-Schwinger field has the same asymptotic frequency as that of the integral spin fields. However, the asymptotic frequency of the Dirac field is different, and its real part is zero. For the extremal case, which is relevant to the supersymmetric consideration, all the spin fields have the same asymptotic frequency, the real part of which is zero. For the imaginary parts of the asymptotic frequencies, it is interesting to see that it has a universal spacing of $1/4M$ for all the spin fields in the single-horizon cases of the Schwarzschild and the extreme Reissner-Nordström black holes. The implications of these results to the universality of the asymptotic quasinormal frequencies are discussed.

description: The relation between the spectral density of the QCD Dirac operator at nonzero baryon chemical potential and the chiral condensate is investigated. We use the analytical result for the eigenvalue density in the microscopic regime which shows oscillations with a period that scales as 1/V and an amplitude that diverges exponentially with the volume $V=L^4$. We find that the discontinuity of the chiral condensate is due to the whole oscillating region rather than to an accumulation of eigenvalues at the origin. These results also extend beyond the microscopic regime to chemical potentials $μ\sim 1/L$.

description: This paper presents a conceptual framework, known as systems development, for designing, selecting, and evaluating information systems. Techniques are developed that aid farm managers in choosing an accounting system. Six farmers took part in case studies testing the selection techniques. The participating farmers exhibited great diversity in the preferred design of their accounting systems and the manner in which they desired reports to be presented. This diversity suggests that system selection is an important aspect of implementing an accounting system.

description: We employed the Skyrme-Hartree-Fock model to investigate the density distributions and their dependence on nuclear shapes and isospins in the superheavy mass region. Different Skyrme forces were used for the calculations with a special comparison to the experimental data in $^{208}$Pb. The ground-state deformations, nuclear radii, neutron skin thicknesses and $α$-decay energies were also calculated. Density distributions were discussed with the calculations of single-particle wavefunctions and shell fillings. Calculations show that deformations have considerable effects on the density distributions, with a detailed discussion on the $^{292}$120 nucleus. Earlier predictions of remarkably low central density are not supported when deformation is allowed for.

description: A multiperiod programming model was used to simulate the effects of lower marginal income tax rates, the soil and water conservation deduction, and the cash tax accounting option on firm growth for a "representative" farm operating in the Alabama Black Belt region. Results show the lowered marginal income tax rates associated with the Economic Recovery Tax Act (ERTA) of 1981 provide a positive growth stimulus to the modeled firm as measured by accumulated net worth over a 10-year planning horizon. The soil and water conservation deduction in general provides greater tax relief to the modeled firm than either the ERTA income tax rate changes or the cash tax accounting provision. Important complementary and substitute relationships were found to exist between marginal income tax rates and the various tax provisions studied, implying care must be exercised when attempting to evaluate the impact on farm firms of changes in tax policy.

description: An example of agricultural researching technology transfer and implications for the fiscal coordination and conduct of agricultural research programs is presented. Uniform Soybean Tests conducted in four Southern States are used to estimate the potential for transferability of soybean variety research among homogeneous sub-areas. The results indicate a high degree of transferability among the sub-areas. Coordinated management of soybean variety research could potentially provide more effective expenditure of soybean breeding research investments. Additionally, the concept or research transferability is not limited to soybeans or soybean variety research. Increased coordination of agricultural research investments by individual states may enhance existing benefits.

description: Vector-autoregressive-moving-average (VARMA) modeling was used to identify distributed lag relationships among farm tractor derived demand variables and to provide a basis for formally testing the hypothesis that the price of new tractor horsepower is exogeneous to its quantity demanded. Similar causality tests were used for a number of other explanatory variables, including the interest rate, price of diesel fuel, and price of used tractors. Results indicate that several lagged variables are significant causal factors and that the dynamic nature of the demand structure cannot be ignored when explaining tractor demand.

description: We formulate and discuss a 4-dimensional SUSY version of an A4 model for tri-bimaximal neutrino mixing which is completely natural. We also study the next-to-the-leading corrections and show that they are small, once the ratios of A4 breaking VEVs to the cutoff are fixed in a specified interval. We also point out an interesting way of presenting the A4 group starting from the modular group. In this approach, which could be interesting in itself as an indication on a possible origin of A4, the lagrangian basis where the symmetry is formulated coincides with the basis where the charged leptons are diagonal. If the same classification structure in A4 is extended from leptons to quarks, the CKM matrix coincides with the unit matrix in leading order and a study of non leading corrections shows that the departures from unity of the CKM matrix are far too small to accomodate the observed mixing angles.

description: A multi-product cost function model was used to analyze energy demand in various agricultural subsectors. This approach has advantages over previously used approaches since it reduces aggregation bias, considers technological jointness, and provides various disaggregative measures related to energy input demand. When fitted to West Virginia county level data, labor and miscellaneous inputs in crop and livestock production were found to be substitutes for energy, while capital, machinery, and fertilizer were complementary to energy. Energy demand was inelastic and increases in machinery prices had the largest reduction effect on energy demand. Technological change was found to be capital, machinery, and fertilizer using, but it was labor and energy saving. Analyses indicated that the elasticity of demand for energy inputs with respect to livestock output was significantly larger than the elasticity with respect to crop output.

description: We present MUSE observations of the gas-rich major-merger BR1202-0725 at z~4.7, which constitutes one of the most overdense fields known in the early Universe. We utilise these data in conjunction with existing ALMA observations to compare and contrast the spatially resolved ionised- and cool-gas content of this system which hosts a quasar (QSO), a sub-millimeter galaxy (SMG), the two known optical companions ("LAE1", "LAE2"), and an additional companion discovered in this work "LAE3" just 5 arcsec to the North of the QSO. We find that QSO BR1202-0725 exhibits a large Ly$α$ halo, covering $\approx55$ pkpc on-sky at surface brightness levels of SB$\geq$1E-17 erg/s/cm$^2$/arcsec$^2$. In contrast, the SMG, of similar far-infrared luminosity and star formation rate (SFR), does not exhibit such a Ly$α$ halo. The QSO's halo exhibits high velocity widths ($\sim1000$ km/s) but the gas motion is to some extent kinematically coupled with the previously observed [CII] bridge between the QSO and the SMG. We note that the object known in the literature as LAE2 shows no local peak of Ly$α$ emission, rather, its profile is more consistent with being part of the QSO's extended Ly$α$ halo. The properties of LAE3 are typical of high-redshift LAEs; we measure F$_{\rm{Lyα}}$(LAE3) = $0.24\pm$0.03E-16 erg/s/cm$^2$, corresponding to SFR$_{\rm{Lyα}}\approx\ $5.0$\pm$0.5 M${_\odot}$/yr. The velocity width is $Δv$(LAE3) $\approx 400$ km/s, and equivalent width EW$_0$(Ly$α_{\,5σ}^{\,lim})\geq 34.05$ $\\A$, consistent with star formation being the primary driver of Ly$α$ emission. We also note a coherent absorption feature at $\sim -400$km/s in spectra from at least three objects; the QSO, LAE1 and "LAE2" which could imply the presence of an expanding neutral gas shell with an extent of at least $24$ pkpc.

description: Conditional Value at Risk (CVaR) is a family of "coherent risk measures" which generalize the traditional mathematical expectation. Widely used in mathematical finance, it is garnering increasing interest in machine learning, e.g., as an alternate approach to regularization, and as a means for ensuring fairness. This paper presents a generalization bound for learning algorithms that minimize the CVaR of the empirical loss. The bound is of PAC-Bayesian type and is guaranteed to be small when the empirical CVaR is small. We achieve this by reducing the problem of estimating CVaR to that of merely estimating an expectation. This then enables us, as a by-product, to obtain concentration inequalities for CVaR even when the random variable in question is unbounded.

description: In order to study the circumnuclear star-forming activity along the Hubble sequence, we cross-correlate the Sloan Digital Sky Survey Data Release 2 (SDSS DR2) with the Third Reference Catalog of Bright Galaxies (RC3) to derive a large sample of 1015 galaxies with both morphological and spectral information. Among these, 385 sources are classified as star-forming galaxies and the SDSS fibre covered the circumnuclear regions (0.2 $-$ 2.0 kpc). By using the spectral synthesis method to remove the contribution from the underlying old stellar population, we measure the emission lines fluxes accurately which are then used to estimate the star formation rates(SFRs). Our main findings are that: (1) Early-type spirals show much larger H$α$ luminosities and hence higher SFRs, they also suffer more extinctions than late-type ones. The equivalent widths (EWs) of H$α$ emission lines show the similar trend, however, the very late types (Sdm $\sim$ Irr) do have large fractions of high EWs. (2) We confirm that D$_n(4000)$ has strong correlation with the strengthes of metallic absorption lines (such as CN band, G band and Mg Ib). Both these lines and the Balmer absorption lines show interesting variations between Sbc to Sd type galaxies. (3) The bar structure tightly relates with the enhanced star forming activity, this effect is even more significant in the early-type spirals. But we should note that the bar structure is not a necessary or sufficient condition for galaxies to harbor circumnuclear star formations.

description: For many small- and medium-vocabulary tasks, audio-visual speech recognition can significantly improve the recognition rates compared to audio-only systems. However, there is still an ongoing debate regarding the best combination strategy for multi-modal information, which should allow for the translation of these gains to large-vocabulary recognition. While an integration at the level of state-posterior probabilities, using dynamic stream weighting, is almost universally helpful for small-vocabulary systems, in large-vocabulary speech recognition, the recognition accuracy remains difficult to improve. In the following, we specifically consider the large-vocabulary task of the LRS2 database, and we investigate a broad range of integration strategies, comparing early integration and end-to-end learning with many versions of hybrid recognition and dynamic stream weighting. One aspect, which is shown to provide much benefit here, is the use of dynamic stream reliability indicators, which allow for hybrid architectures to strongly profit from the inclusion of visual information whenever the audio channel is distorted even slightly.

description: When elementary prices move strictly proportionately, aggregation over a group of diverse products is valid, and group demand responses can be decomposed into quality and quantity responses. This study shows that when relative elementary prices and group prices are stochastically independent, a similar decomposition is valid. Empirical results suggest consumers respond to changes in prices and income mostly by altering the quality of meat products. These findings imply that using commercial disappearance as a proxy for food demand can be misleading for policy analysis.

description: We present the first results on variability of very low mass stars and brown dwarfs belonging to the 5 Myr Lambda Orionis cluster (Collinder 69). We have monitored almost continuously in the J filter a small area of the cluster which includes 12 possible members of the cluster during one night. Some members have turned to be short-term variable. One of them, LOri167, has a mass close to the planetary mass limit and its variability might be due to instabilities produced by the deuterium burning, although other mechanism cannot be ruled out.

description: We examine an unusual phenomenon where, in tilted magnetic fields near magic angles parallel to crystallographic planes, a "giant" resonant Nernst signal has been observed by Wu et al.[Phys. Rev. Lett. 91 56601(2003)] in the metallic state of an organic conducting Bechgaard salt. We show that this effect appears to be a general feature of these materials, and is also present in the field induced spin density wave phase with even larger amplitude. Our results place new restrictions on models that treat the metallic state as an unconventional density wave or as a state with finite Cooper pairing.
