description: Resumen En un entorno económico más globalizado, la competitividad de las empresas se convierte en una necesidad estratégica de supervivencia, sobre todo en el sector agroindustrial. Ante los cambios observados en los mercados y los hábitos del consumidor, las empresas deben adaptarse adoptando las estrategias adecuadas. El objetivo de este trabajo se centra en determinar los principales factores explicativos de la propensión exportadora de la industria agroalimentaria española y catalana. Los datos utilizados proceden de la Encuesta de Estrategias Empresariales (ESEE). Para alcanzar este objetivo, se ha especificado y estimado un modelo que tiene en cuenta la naturaleza microeconómica de los datos utilizados. La cualificación del personal, la presencia de capital extranjero, las buenas perspectivas de los mercados y la antigüedad de la empresa parecen ser los principales determinantes a la hora de decidir exportar. Las variables de dimensión y de concentración, sin embargo, son mucho más determinantes a la hora de decidir cuánto exportar. Palabras Clave: Industria Agroalimentaria, estrategias empresariales, exportación, Cataluña. In an increasing globalized environment, the agrofood firms' competitiveness becomes a strategic need for future survival. Recent changes both in agrofood markets and consumers' habits have encourage firms to adopt adequate managerial strategies. The objective of this paper is to determine main factors affecting the exporting behavior of the agro-food firms. Data come from the Survey on Firms Strategies (ESEE). To achieve this objective, a model has been specified and estimated taking into account the characteristics of the database. The personnel qualification, the existence of foreign capital, the existence of potential benefits in foreign market and the firm' age are the main factors explaining the agrofood firm decision to export. On the other hand, variables denoting firm size and domestic market concentration and saturation are more important to explain export intensity.
Generalized B-spline surfaces for ship hull form representation and modeling

Subjects: subject: 004 Data processing Computer sciences

description: Ship hull form modeling is currently a time-consuming task, due to the limited capabilities of the underlying surface representation. Tensor-product B-splines are almost exclusively used in this field, but are limited to four-sided surfaces, which in general does not allow to represent complex surfaces such as ship hull forms easily. This thesis introduces generalized B-spline surfaces to overcome the limitation of B-splines to four-sided surfaces and shows how hull form modeling is simplified and quality of results improved based on this surface representation.

description: The cluster size dependence of superconductivity in the conventional two-dimensional Hubbard model, commonly believed to describe high-temperature superconductors, is systematically studied using the Dynamical Cluster Approximation and Quantum Monte Carlo simulations as cluster solver. Due to the non-locality of the d-wave superconducting order parameter, the results on small clusters show large size and geometry effects. In large enough clusters, the results are independent of the cluster size and display a finite temperature instability to d-wave superconductivity.

Lightlike simultaneity, comoving observers and distances in general relativity
Creators: name: Bolós, V. J.
Publisher: name: arXiv
Year: 2005
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We state a condition for an observer to be comoving with another observer in general relativity, based on the concept of lightlike simultaneity. Taking into account this condition, we study relative velocities, Doppler effect and light aberration. We obtain that comoving observers observe the same light ray with the same frequency and direction, and so gravitational redshift effect is a particular case of Doppler effect. We also define a distance between an observer and the events that it observes, that coincides with the known affine distance. We show that affine distance is a particular case of radar distance in the Minkowski space-time and generalizes the proper radial distance in the Schwarzschild space-time. Finally, we show that affine distance gives us a new concept of distance in Robertson-Walker space-times, according to Hubble law.

description: The orbits of visual binary systems still attract many of the working groups in astronomy. These orbits are the most important and reliable source of the stellar masse. In the present paper, we are going to compute orbits and dynamical masses of some visual binaries using an independent code. We used Kowalsky method to compute the geometrical elements. The dynamical elements (the period and the time of the periastron passage) are computed by implementing the double areal constant. We used the developed code to calculate the orbits for the four visual binaries, WDS J02262+3428, WDS J14310-0548, WDS J17466-0354, and WDS J12422+2622. We introduced a new orbit of the neglected visual binary WDS J17466-0354 and modified orbits for the rest three binaries. Using the Gaia DR2 parallaxes we computed the total masses of the systems. Comparing the adopted total masses with those derived from the spectral type relation revealed good agreement.

description: L’introduction des caméras portables au sein des forces de sécurité (police, gendarmerie, pompiers) est d’actualité. Mise en place dans une perspective d‘amélioration des relations citoyens-police dans une logique de transparence lors des interventions, les avis « terrains » divergent. Certains y sont favorables voyant un effet de protection par la transparence , d’autres estiment qu’elle a des effets négatifs sur les interventions instaurant un climat de voyeurisme, et de surveillance.
 En tout état de cause, à une heure où la France débute ces expérimentations, il est opportun de s’interroger sur les recherches scientifiques effectuées sur cette thématique à l’international.

description: Let $M_n(\mathbb{Z})$ the ring of $n$-by-$n$ matrices with integral entries, and $n \geq 2$. This paper studies the set $G_n(\mathbb{Z})$ of pairs $(A,B) \in M_n(\mathbb{Z})^2$ generating $M_n(\mathbb{Z})$ as a ring. We use several presentations of $M_{n}(\mathbb{Z})$ with generators $X=\sum_{i=1}^n E_{i+1,i}$ and $Y=E_{11}$ to obtain the following consequences. \begin{enumerate} \item Let $k \geq 1$. Then the rings $M_n(\mathbb{Q})^k$ and $\bigoplus_{j=1}^{k} M_{n_j} (\mathbb{Z})$, where $n_1, ..., n_k \geq 2$ are pairwise relatively prime, have presentations with 2 generators and finitely many relations. \item Let $D$ be a commutative domain of sufficiently large characteristic over which every finitely generated projective module is free. We use 4 relations for $X$ and $Y$ to describe all representations of the ring $M_{n}(D)$ into $M_{m}(D)$ for $m \geq n$. \item We obtain information about the asymptotic density of $G_n(F)$ in $M_n(F)^2$ over different fields, and over the integers. \end{enumerate}
description: 33 pages. One typo has been corrected: in the first line of the proof of Theorem 2.19 on p. 16, $G_n(\mathbb{F}_q)$ was replaced with $M_n(\mathbb{F}_q)^2-G_n(\mathbb{F}_q)$. No other changes have been made

description: On-surface synthesis has recently emerged as an effective route towards the atomically precise fabrication of graphene nanoribbons of controlled topologies and widths. However, whether and to which degree structural disorder occurs in the resulting samples is a crucial issue for prospective applications that remains to be explored. Here, we experimentally identify missing benzene rings at the edges, which we name "bite" defects, as the most abundant type of disorder in armchair nanoribbons synthesized by the bottom-up approach. First, we address their density and spatial distribution on the basis of scanning tunnelling microscopy and find that they exhibit a strong tendency to aggregate. Next, we explore their effect on the quantum charge transport from first-principles calculations, revealing that such imperfections substantially disrupt the conduction properties at the band edges. Finally, we generalize our theoretical findings to wider nanoribbons in a systematic manner, hence establishing practical guidelines to minimize the detrimental role of such defects on the charge transport. Overall, our work portrays a detailed picture of "bite" defects in bottom-up armchair graphene nanoribbons and assesses their effect on the performance of carbon-based nanoelectronic devices.

description: The magnetic susceptibility of the 1/1 approximants to icosahedral quasicrystals in a series of Cd85-xMgxTb15 (x = 5, 10, 15, 20) alloys was investigated in detail. The occurrence of antiferromagnetic to spin-glass-like transition was noticed by increasing Mg. Transmission electron microscopy analysis evidenced a correlation between the magnetic transition and suppression of the monoclinic superlattice ordering with respect to the orientation of the Cd4 tetrahedron at T > 100 K. The possible origins of this phenomenon were discussed in detail. The occurrence of the antiferromagnetic to spin-glass -like magnetic transition is associated with the combination of chemical disorder due to a randomized substitution of Cd with Mg and the orientational disorder of the Cd4 tetrahedra.

description: We present the first discovery of dust-reddened quasars (red quasars) in the high-z universe (z >5.6). This is a result from the Subaru High-z Exploration of Low-Luminosity Quasars (SHELLQs) project, which is based on the sensitive multi-band optical imaging data produced by the Hyper Suprime-Cam (HSC) Subaru Strategic Program survey. We identified four red quasar candidates from the spectroscopically confirmed 93 high-z quasars in the SHELLQs sample, based on detections in the Wide-field Infrared Survey Explorer (WISE) data at 3.4 and 4.6 um (rest-frame ~5000-6500 A). The amount of dust reddening was estimated with spectral energy distribution (SED) fits over optical and mid-infrared wavelengths. Two of the four candidates were found to be red quasars with dust reddening of E(B-V) > 0.1. The remaining SHELLQs quasars without individual WISE detections are significantly fainter in the WISE bands and bluer than the red quasars, although we did detect them in the W1 band in a stacked image. We also conducted the same SED fits for high-z optically-luminous quasars, but no red quasar was found. This demonstrates the power of Subaru HSC to discover high-z red quasars, which are fainter than the limiting magnitudes of past surveys in the rest-frame ultraviolet, due to dust extinction.

description: PHASECam is the fringe tracker for the Large Binocular Telescope Interferometer (LBTI). It is a near-infrared camera which is used to measure both tip/tilt and fringe phase variations between the two adaptive optics (AO) corrected apertures of the Large Binocular Telescope (LBT). Tip/tilt and phase sensing are currently performed in the $H$ (1.65 $μ$m) and $K$ (2.2 $μ$m) bands at 1 kHz, but only the $K$-band phase telemetry is used to send corrections to the system in order to maintain fringe coherence and visibility. However, due to the cyclic nature of the fringe phase, only the phase, modulo 360 deg, can be measured. PHASECam's phase unwrapping algorithm, which attempts to mitigate this issue, occasionally fails in the case of fast, large phase variations or low signal-to-noise ratio. This can cause a fringe jump, in which case the OPD correction will be incorrect by a wavelength. This can currently be manually corrected by the operator. However, as the LBTI commissions further modes which require robust, active phase control and for which fringe jumps are harder to detect, including multi-axial (Fizeau) interferometry and dual-aperture non-redundant aperture masking interferometry, a more reliable and automated solution is desired. We present a multi-wavelength method of fringe jump capture and correction which involves direct comparison between the $K$-band and $H$-band phase telemetry. We demonstrate the method utilizing archival PHASECam telemetry, showing it provides a robust, reliable way of detecting fringe jumps which can potentially recover a significant fraction of the data lost to them.

description: Reducing the impact of seismic activity on the motion of suspended optics is essential for the operation of ground-based gravitational wave detectors. During periods of increased seismic activity, low-frequency ground translation and tilt cause the Advanced LIGO observatories to lose `lock', reducing their duty cycles. This paper applies modern global-optimisation algorithms to aid in the design of the `sensor correction' filter, used in the control of the active platforms. It is shown that a particle swarm algorithm that minimises a cost-function approximating the differential RMS velocity between platforms can produce control filters that perform better across most frequencies in the control bandwidth than those currently installed. These tests were conducted using training data from the LIGO Hanford Observatory seismic instruments and simulations of the HAM-ISI (Horizontal Access Module Internal Seismic Isolation) platforms. These results show that new methods of producing control filters are ready for use at LIGO. The filters were implemented at LIGO's Hanford Observatory, and use the resulting data to refine the cost function.

Is Thermal Emission in Gamma-Ray Bursts Ubiquitous?

Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The prompt emission of gamma-ray bursts has yet defied any simple explanation, despite the presence of a rich observational material and great theoretical efforts. Here we show that all the types of spectral evolution and spectral shapes that have been observed can indeed be described with one and the same model, namely a hybrid model of a thermal and a non-thermal component. We further show that the thermal component is the key emission process determining the spectral evolution. Even though bursts appear to have a variety of, sometimes complex, spectral evolutions, the behaviors of the two separate components are remarkably similar for all bursts, with the temperature describing a broken power-law in time. The non-thermal component is consistent with emission from a population of fast cooling electrons emitting optically-thin synchrotron emission or non-thermal Compton radiation. This indicates that these behaviors are the fundamental and characteristic ones for gamma-ray bursts.

description: It is a persistent problem in condensed matter physics that glasses exhibit vibrational and thermal properties that are markedly different from those of crystals. While recent works have advanced our understanding of vibrational excitations in glasses at the harmonic approximation limit, efforts in understanding finite-temperature anharmonic processes have been limited. It is well known that phonons in crystals couple through phonon-phonon interactions, an extremely efficient mechanism for anharmonic decay that is also important in glasses. Here, however, we show that an additional anharmonic channel of different origin emerges in the case of glasses, which induces intermittent rearrangements of particles. We have found that thermal vibrations in glasses trigger transitions among numerous different local minima of the energy landscape, which, however, are located within the same wide (meta)basin. These processes generate motions that are different from both diffusive and out-of-equilibrium aging dynamics. We suggest that the intermittent rearrangements accompanying thermal fluctuations are crucial features distinguishing glasses from crystals.

CTCF motif positive 0.2 kb bins were filtered out from each group. Motif positive GoM, LoM and “No change” 0.2 kb bin sequences were subjected to de novo motif search by using MEME suite.
Performance evaluation of the ISDB-T standard for multimedia services
Creators: name: Wang, Xinrong
Publisher: name: University of British Columbia
Year: 2009

description: The Integrated Services Digital Broadcasting - Terrestrial (ISDB-T) standard is one of the three dominant digital television terrestrial broadcasting standards. It employs concatenated coding and OFDM techniques to combat fading and multipath channel impairments. ISDB-T operates in 6, 7, or 8 MHz channel bandwidths, with each channel supporting up to three different services. These services may use different convolutional code rates, modulation schemes, and time interleaving lengths to meet different quality of service requirements. In this thesis, an ISDB-T baseband simulation model is implemented using SPW™, C, and C++, and validated. This model is built to accommodate all of the possible ISDB-T system configurations. Since the target BER in ISDB-T is very low, for example, 1x10⁻¹¹ for high definition television, it is impractical to obtain the BER directly using software simulation. A Markov chainbased semi-analytic method is used, which agrees well with available simulation results in nonfading environments. The semi-analytic results are quite different from the simulation results in fading channels, especially at very low Doppler frequencies. The channel undergoes deep fades at very low Doppler frequencies, causing a large number of symbol errors during these fading periods. The Markov chain model does not model these kinds of long error bursts very well. A numerical analysis is provided for very slow Rayleigh fading. The results of the numerical analysis agree quite well with the simulation results.

description: We discuss the effect of Kaluza-Klein (KK) modes of bulk metric perturbations on the second Randall-Sundrum (RS II) type brane cosmology, taking the possible backreaction in the bulk and on the brane into account. KK gravitons may be produced via quantum fluctuations during a de Sitter (dS) inflating phase of our brane universe. In an effective 4-dimensional theory in which one integrates out the extra-dimensional dependence in the action, KK gravitons are equivalent to massive gravitons on the brane with masses $m>3H/2$, where $H$ represents the expansion rate of a dS brane. Thus production of even a tiny amount of KK gravitons may eventually have a significant impact on the late-time brane cosmology. As a first step to quantify the effect of KK gravitons on the brane, we calculate the effective energy density and pressure for a single KK mode. Surprisingly, we find that a KK mode behaves as cosmic dust with a negative energy density on the brane. We note that the bulk energy density of a KK mode is positive definite and there occurs no singular phenomenon in the bulk.

description: It is proposed to consider dark matter as a perfect dilaton-spin fluid (with particles endowed with intrinsic spin and dilaton charge) in the framework of a gravitational theory with a Weyl-Cartan geometrical structure. The modified Friedmann-Lema\^ıtre equation (with a cosmological term) is obtained for the homogeneous and isotropic Universe filled with the dilaton-spin dark matter. On the basis of this equation, we develop a nonsingular cosmological model starting from an inflation-like stage (for super-stiff equation of state), passing radiation-dominated and matter-dominated decelerating stages and turning into a post-Friedmann accelerating era.

description: Production uncertainty is commonly believed to be an impediment to the adoption of less pesticide-intensive methods in agriculture such as integrated pest management (IPM). To investigate the effects of pest control inputs on yields and yield variability, data from a cross-section of San Joaquin Valley cotton producers were analyzed in a heteroskedastic production model. The results suggest that yields are increasing with soil quality, crop rotation, frequency of field monitoring, and the use of independent pest control advisors. Yield variability was not found to be significantly affected by production inputs, including pesticides and IPM practices with the exception of frequent contact with extension farm advisors which was found to contribute to reduced yield variability.

description: A source differentiated AIDS model is specified to estimate Japanese meat import demand. Block separability and product aggregation are rejected at conventional levels of significance. The model with the block substitutability restriction explains more than 95% of data variation. The empirical results indicate that the U.S. has the largest potential for beef exports to Japan. Taiwan is in a strong position in the pork market, and Thailand and China are strong in the poultry market. The U.S. competes with Canada and Taiwan in the pork market, but the competition between Taiwan and European countries is the strongest in the market. The U.S. competes with Thailand in the poultry market, where the U.S. is the most vulnerable.

description: The cyclical nature of numbers and prices of sheep and lambs was examined from 1924 through 1993. Tests for structural change also were conducted utilizing the minimization of Akaike's information criterion (MAIC). Results indicate that cyclical length in both stock sheep numbers and lamb prices has decreased over time, with a current 10- and 27-year cycle in stock sheep numbers and nine- and 27-year cycle lamb prices. Structural changes occurred in 1951 and 1968 for stock sheep number and in 1952 and 1972 for lamb prices.

description: We have developed two radiation-hard ASICs for optical data transmission in the ATLAS pixel detector at the LHC at CERN: a driver chip for a Vertical Cavity Surface Emitting Laser (VCSEL) diode for 80 Mbit/s data transmission from the detector, and a Bi-Phase Mark decoder chip to recover the control data and 40 MHz clock received optically by a PIN diode. We have successfully implemented both ASICs in 0.25 micron CMOS technology using enclosed layout transistors and guard rings for increased radiation hardness. We present results of the performance of these chips, including irradiation with 24 GeV protons up to 61 Mrad (2.3 x 10e15 p/cm^2).

description: Cow-calf prices are determined by interaction of many factors. At a particular auction, cow-calf pair prices often had a range of 75% of the mean price. This variability suggests that producers need to be informed regarding cow-calf price determinants. This study uses auction data during 1993 to estimate price differentials associated with cow-calf pair characteristics using a hedonic model. Cow breed, age, health, conditions, horns, frame, and whether the cow had been bred back were significant price determinants. Calf weight, health, and frame had significant price impacts. Highest prices were paid for pens containing 9-12 pairs of young Angus, dehorned, bred back, healthy cows with heavy healthy calves.

description: Technical efficiency of rural water utilities is determined using frontier production functions. An indirect production function is developed to model the two-step production process of a local government-controlled firm. Data from 26 rural Nevada water utilities are used to estimate inefficiency in terms of firm-specific variables. A multistep estimation procedure is used instead of single-step maximum likelihood estimation. Model selection tests are used to choose the best model. Privately owned utilities are most efficient; self-governing water districts are the least efficient. Municipal governments operate the most and least efficient utilities.

description: We present the photometric determination of the bright-end (L_Lya>10^43.5 erg/s) of the Lya luminosity function (LF) within four redshifts windows in the interval 2.210^43.3 erg/s) Lya-emitting candidates. We test our selection with two spectroscopic follow-up programs at the GTC telescope, confirming ~89% of the targets as line-emitting sources, with ~64% being genuine z~2.2 QSOs. We extend the 2.22 AGN/QSOs (likely dominant in our samples) are described by a structurally different LF than z>2 star-forming LAEs, namely with L^*_QSOs ~ 100 L^*_LAEs and Phi^*_QSOs ~ 10^-3 Phi^*_LAEs. Finally, our method identifies very efficiently as high-z line-emitters sources without previous spectroscopic confirmation, currently classified as stars (~2000 objects in each redshift bin, on average). Assuming a large predominance of Lya-emitting AGN/QSOs in our samples, this supports the scenario by which these are the most abundant class of z>2 Lya emitters at L_Lya>10^43.3 erg/s.

description: Among the 17 United Nations Sustainable Development Goals (SDGs), SDG #11 aims to make future cities resilient and sustainable while, SDG #6 aims to ensure availability and sustainable management of water and sanitation for all. In this study, the following five attributes for assessing wastewater infrastructure that can support sustainable cities are distilled from the targets set for SDG #11, #6 and other wastewater-related SDGs: reuse-quality water recovery; safe pathogen reduction; energy use and recovery in wastewater treatment; biofertilizer recovery from wastewater; and emission reduction in wastewater treatment. A total of 36 process parameters are derived to quantify these five attributes. Application of this sustainability-based approach in evaluating an emergent algal-based sewage treatment and resource recovery (STaRR) system against the traditional activated sludge-base sewage treatment practices is presented. This study emphasizes the contribution and the influence of wastewater infrastructures for the sustainability of cities and suggests that the emergent STaRR system is a sustainable pathway to provide wastewater utility service to future cities and to accomplish UN SDGs and targets.

description: Recognition of conditions which support nocturnal extreme fire behavior (EFB) can pose a challenge to forecasters, especially since numerical weather prediction (NWP) tools are limited in their ability to initialize highly dynamic, but relatively small-scale features. Large fires can drastically alter nocturnal stability which can quickly lead to nocturnal EFB and directly impact public safety.  During the night of 22-23 Apr 2009 the Highway 31 Fire in Horry County, SC exhibited EFB when NWP indicated a stabilizing environment. In a matter of a few hours, the fire consumed 2000 ha, destroyed 76 homes and damaged another 96 structures. To assess the potential for nocturnal EFB, it is imperative forecasters conduct an analysis which includes: antecedent conditions, ventilation rate, visual observations, National Weather Service (NWS) Weather Surveillance Radar (WSR-88D) imagery, and stability profiles.  This research provides weather forecasters with factors that contributed to the nocturnal EFB observed during the Highway 31 Horry County fire, an overview of a Nocturnal Fire Growth (NFG) sounding, how to assess potential nocturnal EFB through a decision tree, and the Impact-based Decision Support service (IDSS) implications for the 22-23 Jun 2011 Juniper Road fire in Pender County, NC.

description: The incidence of benefits and costs from controlling rangeland grasshoppers on public grazing lands poses problems of economic efficiency and distributional equity. Public grasshopper control programs operate like public disaster assistance. However, grasshopper infestations are an insurable risk. This article proposes a rangeland grasshopper insurance program which reduces the economic inefficiencies and distributional inequities of the existing program.
