description: We propose a new, twistor string theory inspired formalism to calculate loop amplitudes in N=4 super Yang-Mills theory. In this approach, maximal helicity violating (MHV) tree amplitudes of N=4 super Yang-Mills are used as vertices, using an off-shell prescription introduced by Cachazo, Svrcek and Witten, and combined into effective diagrams that incorporate large numbers of conventional Feynman diagrams. As an example, we apply this formalism to the particular class of MHV one-loop scattering amplitudes with an arbitrary number of external legs in N=4 super Yang-Mills. Remarkably, our approach naturally leads to a representation of the amplitudes as dispersion integrals, which we evaluate exactly. This yields a new, simplified form for the MHV amplitudes, which is equivalent to the expressions obtained previously by Bern, Dixon, Dunbar and Kosower using the cut-constructibility approach.

description: Objectivos: A excessiva ingestão de sal tem vindo a aumentar consideravelmente nas últimas décadas e encontra-se muito associada ao consumo de produtos processados, entre os quais os cárneos. O presente trabalho, fruto da colaboração entre a Faculdade de Medicina Veterinária da Universidade Lusófona com a Jerónimo Martins e a Sicasal, tem como objetivo determinar o potencial da utilização de salicórnia (“sal verde”) como alternativa ao sal em enchidos. Para tal foram avaliadas bioatividades com potencial para a saúde humana e para o shelflife do produto, contra bactérias patogénicas alimentares e uma metaloproteínase de matriz, a MMP-9, comumente associada a estados de inflamação e a patologias tumorais.


Materiais e métodos: A salicórnia utilizada foi na sua forma desidratada como produto comercial. Foi realizada uma extração polar e apolar sendo o seu material recolhido e congelado a -80ºC para futuras análises. As atividades anti-bacterianas foram avaliadas contra Escherichia coli, através do método de diluições sucessivas. O potencial inibitório da MMP-9 foi determinado através de um ensaio fluorométrico e também por zimografia de gelatina.


Resultados: Os extratos polares e apolares de salicórnia reduziram o crescimento de E. coli, de uma forma dose-dependente. Ambos os extratos também apresentaram atividades inibidoras de MMP-9, demonstrando assim um grande potencial de exercer função anti-inflamatória bem como anti-tumoral.


Conclusões: Embora esta seja uma alternativa ao sal, a salicórnia ainda não foi testada em enchidos em Portugal. Os nossos resultados demostram o potencial benéfico da sua aplicação em produtos alimentares, quer a nível de segurança e higiene alimentar, bem como para a saúde humana.

description: The European Union’s cohesion policy and its Structural Funds are key delivery mechanisms to achieve the priorities of smart, sustainable and inclusive growth but there is evidence that rural areas may be receiving an inadequate share of this funding. In the period 2014 to 2020, intermediate and predominantly rural NUTS2 regions in eastern European Member States (EU9) and those regions in southern European Member States (EU7) with high agricultural employment rates are likely to be the main recipients of around of 80% of cohesion funds. This paper contrasts the economic prosperity and employment situation in rural and urban NUTS2 regions of the EU and, in the context of the findings of the EU Framework 7 project ‘RuralJobs’, argues that rural development actors should look beyond CAP funding and adopt an integrated approach which better mobilises Structural Funds, and national and private sector funding, to promote rural employment creation and economic prosperity.

description: We report the results of a new Rosenbluth measurement of the proton form factors at Q^2 values of 2.64, 3.20 and 4.10 GeV^2. Cross sections were determined by detecting the recoiling proton in contrast to previous measurements in which the scattered electron was detected. At each Q^2, relative cross sections were determined to better than 1%. The measurement focussed on the extraction of G_E/G_M which was determined to 4-8% and found to approximate form factor scaling, i.e. μ_p G_E \approx G_M. These results are consistent with and much more precise than previous Rosenbluth extractions. However, they are inconsistent with recent polarization transfer measurements of comparable precision, implying a systematic difference between the two techniques.

Subjects: subject: Astrophysics (astro-ph)

description: A lossy compression algorithm is presented for astronomical images that protects photometric integrity for detected point sources at a user-defined level of statistical tolerance. PHOTZIP works by modeling, smoothing, and then compressing the astronomical background behind self-detected point sources, while completely preserving values in and around those sources. The algorithm also guaranties a maximum absolute difference (in terms of $σ$) between each compressed and original background pixel, allowing users to control quality and lossiness. For present purposes, PHOTZIP has been tailored to FITS format and is freely available over the web. PHOTOZIP has been tested over a broad range of astronomical imagery and is in routine use by the Night Sky Live (NSL) project for compression of all-sky FITS images. Compression factors depend on source densities, but for the canonical NSL implementation, a PHOTZIP (and subsequently GZIP or BZIP2) compressed file is typically 20% of its uncompressed size.

description: Objetivos: Os mastocitomas são neoplasias que, se diagnosticados na pele, são classificados em cutâneos e subcutâneos. O objetivo deste estudo é proceder uma análise comparativa entre os fatores de risco associados a estes tumores.


Material e Métodos: Foram analisados a raça, idade, sexo e localização anatómica da lesão em 633 mastocitomas cutâneos (MCTcut) e 192 mastocitomas subcutâneos (MCTsub). Foi realizada uma análise descritiva, inferencial com análises de correspondência e regressão logística.


Resultados: Não há diferenças entre a idade média à excisão entre MCTcut e MCTsub (8,1 DP=2.9; 8,6 DP=2.8). Em relação ao sexo, as idades médias não diferem e nos MCTcut não há predileção; enquanto nos MCTsub há um predomínio de fêmeas (57,3%, p<0.05). MCTcut - Os SRD foram os mais frequentes (212, 33,5%) apresentando a maior idade média (8,8 DP=3,2, p<0.05), seguidos pelos Labradores (134, 21,2%) e Boxers (46, 7,3%). Os Bulldog franceses e os Pugs foram os que apresentaram   as médias de idade mais baixas (6,5DP=2,5; 6,1DP=1,7). MCTsub – os SRD são os mais frequentes (63, 38,4%) com maior idade média (9.2 DP=3,1), sucedendo-se os Labradores (40, 24,4%) e os Golden Retriever (8, 4,8%). Categorizando pela Fédération Cynologique Internationale, o grupo dos cães Molossóides foi o que apresentou a menor idade média (6,8DP=2,5, p<0.05) ao diagnóstico de MCTsub.


Em ambos MCTs, a localização mais comum foi o membro posterior, com uma média de idade mais alta nos mastocitomas subcutâneos (9,2DP=2.9) do que nos cutâneos (7,7DP=2.7). Nos MCTsub, a análise de correspondência revelou que os Boxers apresentam tendência a lesões na face e pescoço.


Nos MCTcut, os graus mais comuns foram o grau II de Patnaik e baixo grau de Kiupel (558, 88,15%; 509, 80,41%). Os casos de alto grau de Kiupel e grau III de Patnaik apresentaram-se em idades mais tardias (9,4 DP=3.1; 9,2 DP=2.9). Nos MCTsub, o padrão mais comum foi o infiltrativo (73, 38%).


O resultado da regressão logística ajustado para o sexo mostra que a idade é o único fator diferencial entre os MCTs (β=1.08, p=0.01).


Conclusões: Os MCT cutâneos e subcutâneos diferem sobretudo na idade de aparecimento, sendo esta influenciada pela raça. O comportamento biológico dos MCTcut tende a ser mais agressivo em idades mais avançadas.

description: We explore the origin of FUSE and HST STIS far UV spectra of the dwarf nova, EY Cyg, during its quiescence using \emph{combined} high gravity photosphere and accretion disk models as well as model accretion belts. The best-fitting single temperature white dwarf model to the FUSE plus HST STIS spectrum of EY Cygni has T$_{eff} = 24,000$K, log $g = 9.0$, with an Si abundance of 0.1 x solar and C abundance of 0.2 x solar but the distance is only 301 pc. The best-fitting composite model consists of white dwarf with T$_{eff} = 22,000$K, log $g = 9$, plus an accretion belt with T$_{belt} = 36,000$K covering 27% of the white dwarf surface with V$_{belt} sin i = 2000$ km/s. The accretion belt contributes 63% of the FUV light and the cooler white dwarf latitudes contribute 37%. This fit yields a distance of 351 pc which is within 100 pc of our adopted distance of 450 pc. EY Cyg has very weak C {\sc iv} emission and very strong N {\sc v} emission, which is atypical of the majority of dwarf novae in quiescence. We also conducted a morphological study of the surroundings of EY Cyg using direct imaging in narrow nebular filters from ground-based telescopes. We report the possible detection of nebular material^M associated with EY Cygni. Possible origins of the apparently large N {\scv}/C {\sc iv} emission ratio are discussed in the context of nova explosions, contamination of the secondary star and accretion of nova abundance-enriched matter back to the white dwarf via the accretion disk or as a descendant of a precursor binary that survived thermal timescale mass transfer. The scenario involving pollution of the secondary by past novae may be supported by the possible presence of a nova remnant-like nebula around EY Cyg.

Subjects: subject: network security

description: The growing amount of encrypted traffic in todays networks makes deep packet inspection infeasible. In addition, high data rates increase the demand for fast processing of network traffic. Attack detection methods need to be based on light feature vectors that can be generated from encrypted network traffic and are easy to extract, process and analyze. So far experts have selected features based on their intuition and previous research works, but there is no general agreement about the features to use for attack detection in a broad scope. In this work we studied five lightweight feature sets recently proposed in the scientific literature. We compared and evaluated the selected vectors with supervised classification schemes.

description: Independent Vector Analysis (IVA) has emerged in recent years as an extension of Independent Component Analysis (ICA) into multiple sets of mixtures, where the source signals in each set are independent, but may depend on source signals in the other sets. In a semi-blind IVA (or ICA) framework, information regarding the probability distributions of the sources may be available, giving rise to Maximum Likelihood (ML) separation. In recent work we have shown that under the multivariate Gaussian model, with arbitrary temporal covariance matrices (stationary or non-stationary) of the source signals, ML separation requires the solution of a "Sequentially Drilled" Joint Congruence (SeDJoCo) transformation of a set of matrices, which is reminiscent of (but different from) classical joint diagonalization. In this paper we extend our results to the IVA problem, showing how the ML solution for the Gaussian model (with arbitrary covariance and cross-covariance matrices) takes the form of an extended SeDJoCo problem. We formulate the extended problem, derive a condition for the existence of a solution, and propose two iterative solution algorithms. In addition, we derive the induced Cramér-Rao Lower Bound (iCRLB) on the resulting Interference-to-Source Ratios (ISR) matrices, and demonstrate by simulation how the ML separation obtained by solving the extended SeDJoCo problem indeed attains the iCRLB (asymptotically), as opposed to other separation approaches, which cannot exploit prior knowledge regarding the sources' distributions.

description: Objetivos: Os mastocitomas (MCT) são as neoplasias malignas mais frequentes nos cães, contudo a informação sobre os fatores de risco é dispersa e por vezes pouco clara. O objetivo deste estudo foi analisar possíveis fatores de risco associados ao seu desenvolvimento.


Material e Métodos: Este é um estudo retrospetivo sobre MCT diagnosticados no Laboratório Veterinário DNAtech entre 2017 e 2021. Foram recolhidos dados sobre idade, sexo, raça, localização anatómica e código postal da clínica requisitante. Foi realizada uma análise descritiva e inferencial. Foi calculado o Risco de Incidência utilizando-se da população canina do SIAC (Lisboa e Setúbal).


Resultados: 905 MCT caninos foram diagnosticados (~180 casos/ano) e apresentam uma média de idade ao diagnóstico de 8,3 anos DP=2,9. Quanto ao sexo, não há predileção e nem diferenças nas médias das idades. Os cães SRD foram os mais frequentes (n=309, 34,1%) seguidos por Labrador Retriever (197, 21,7%), Boxer (67, 6,7%) e Bulldog francês (64, 6,0%). Estes apresentaram a menor média de idade (6.83 DP=2.5) em oposição aos Beagles (10,3 DP=2.3, p<0.05). Em relação à localização anatómica dos MCT, a mais frequentemente diagnosticada foi no membro posterior (136, 15,0%). Os MCT escrotais apresentaram uma média de idade mais alta (9.00 DP=2.9) quando comparada com as outras localizações. Utilizando a população canina do SIAC, há um risco de incidência anual de 9,27 casos de MT/10.000 cães. Os Boxers foram os cães com maior risco relativo quando comparados com os SRD (7,1, p<0,001) seguidos pelos Shar-pei (6,3, p<0,001) e os Golden Retrievers (5,9, p<0,001).


Conclusões: Os resultados reforçam a idade e a raça como fatores de risco associados ao desenvolvimento de MCT caninos.

description: We review our current knowledge of the solar chemical composition as determined from photospheric absorption lines. In particular we describe the recent significant revisions of the solar abundances as a result of the application of a time-dependent, 3D hydrodynamical model of the solar atmosphere instead of 1D hydrostatic models. This has decreased the metal content in the solar convection zone by almost a factor of two compared with the widely used compilation by Anders & Grevesse (1989). While resolving a number of long-standings problems, the new 3D-based element abundances also pose serious challenges, most notably for helioseismology.

Comparison between the Unified Informational Spin Theory (TGU) and the Classical Model (ΛCDM) Validations with Observational Data and Simulations
Creators: name: Matuchaki
Publisher: name: Zenodo
Year: 2025

description: Description:This study introduces the Unified Theory of Informational Spin (TGU) as an alternative to the ΛCDM model, eliminating the need for dark matter and explaining gravitational stability and the formation of cosmic structures through informational coherence.

Using real observational data from telescopes such as JWST, SDSS, and Planck, and comparing the results with numerical simulations, the paper analyzes galactic rotation curves, gravitational lensing, and the distribution of superclusters under the TGU framework.

The results indicate that TGU accurately reproduces phenomena traditionally attributed to dark matter, with statistical metrics showing lower mean squared error (MSE) and higher correlation (Pearson > 0.96) compared to ΛCDM.

Furthermore, the study discusses the implications of TGU for space exploration, quantum computing, and the fundamental structure of the universe, opening new directions for theoretical and observational physics.

🔹 Key Highlights:✅ An alternative model to dark matter, based on informational coherence.✅ Rigorous comparison with real data, including galactic rotation curves.✅ Application of TGU to cosmic structure, gravitational lensing, and observational statistics.✅ Potential for new discoveries and future experimental validation.

description: La reestructuracion de sector productor de leche de Cantabria durante periodo 1990-2011 ha sido intensa en el marco del regimen de cuotas, pero aun inconclisa. La produccion esta esencialmente en las explotaciones con 300.000 y mas kilos de cuota. Resalta el progeso espectacular de la calidad higienica de la leche y el escaso en la fisico-quimica. El sistema productivo, muy intensivo, ha evolucionado hacia un esquema de alta produccion-alto coste, dificil de mantener en la situacion de volatilidad de precios de la leche y, sobre todo, de los medio de produccion (piensos, energia). La obligada competitividad, a que fuerza el mantenimiento del solido potencial productivo de la region, mas la supresion de lasa cuptas lecheras en 2015, exigen un reflexivo analisis sobre la viabilidad del modelo a medio plazo, para atenuar su excesiva dependencia de las compras de piensos fuera de la explotacion mediante un riguroso control de costes, en particular de alimentacion, y una mayor produccion aprovechando todos los recursos dispnibles y minimas inversiones, con particular atencion al incremento de superficies, mas por arrendamiento que por compra, lo que incidira favorablemente en la cuantia de los pagos directos por superficie previstos en la proxima reforma de la PAC. The restructuring of the sector producing milk during the period 1990-2001 in Cantabria has been intense under the quota system, but still unfinished. Production is mainly on farms with more 300,000 kilos. Highlight the spectacular progress of the hygienic quality of milk and low in chemical. The production system, very intensive, has evolved into a pattern of high production-high cost, difficult to maintain in the situation of volatile milk prices and, above all, the means of production (feed, energy). The competitiveness required, to maintain the strong force production potential of the region, over the abolition of milk quotas in 2015, requires a thoughtful analysis of the model's viability in the medium term to reduce its excessive dependence on feed purchases out of the farm through a rigorous cost control, including feeding, and higher production utilizing all available resources and minimal investment, with particular attention to improving surfaces, rather than lease purchase, which will impact favorably the amount of direct area payments under the forthcoming reform of the CAP.
A general relativistic approach to the Navarro-Frenk-White (NFW) galactic halos

description: In order to study their interplay with large scale cosmic evolution and with relativistic effects, such as gravitational lenses, quintessence sources or gravitational waves, we construct a post-Newtonian fluid framework for the "Navarro-Frenk-White'' (NFW) models of galactic halos that follow from N-body numerical simulations. Since these simulations are unable to resolve regions very near the halo center, the extrapolation of the fitting formula leads to a spherically averaged "universal'' density profile that diverges at the origin. We remove this inconvenient feature by replacing a small central region of the NFW halo with an interior Schwarzschild solution with constant density, continuously matched to the remaining NFW spacetime. A model of a single halo, as an isolated object with finite mass, follows by smoothly matching the NFW spacetime to a Schwarzschild vacuum exterior along the virial radius, the physical "cut-off'' customarily imposed, as the mass associated with NFW profiles diverges asymptotically. Numerical simulations assume weakly interacting collisionless particles, hence we suggest that NFW halos approximately satisfy an "ideal gas'' type of equation of state, where mass-density is the dominant rest--mass contribution to matter--energy, with the internal energy contribution associated with an anisotropic kinetic pressure. We show that, outside the central core, this pressure and the mass density roughly satisfy a polytropic relation. Since stellar polytropes are the equilibrium configurations in Tsallis' non-extensive formalism of Statistical Mechanics, we argue that NFW halos might provide a rough empirical estimate of the free parameter $q$ of Tsallis' formalism.

description: Objectives: Over the last two decades, bacterial mucosal colonization, particularly involving non-H. pylori helicobacters (NHPH), has been highlighted as a potential oncogenic factor in feline gastric lymphoma and poorly differentiated large intestinal adenocarcinoma. Our aim was to validate simple molecular diagnostic techniques to identify the presence of specific Helicobacter species in feline gastrointestinal (GI) tract.


Materials and Methods: DNA was extracted from 25 paraffin-embedded tissue from any portion of the GI tract with a previous histopathological diagnosis of lymphoma or gastric adenocarcinoma. The presence of Helicobacter spp. was performed by PCR. All PCR-positive samples were sequenced, and the sequenced PCR products were compared to the GenBank/EMBL/DDBJ databases using the Basic Local Alignment Search Tool (BLAST).


Results: Six samples (33,3%) were Helicobacter spp. PCR-positive. H. heilmannii was the most frequent species, identified in 4 animals. H. ailurogastricus (n=1), H. felis and H. bizzozeronii, were also detected. These last two Helicobacter species were identified in the same cat sample.


Conclusions: Our preliminary results confirm the occurrence of NHPH in distinct regions of the feline gastrointestinal tract. However, more samples will be needed in order to establish a correlation between specific Helicobacter species and feline gastrointestinal manifestations.

description: Establecer y valorar los impactos marginales de la olivicultura ecologica despues de la aplicacion de la condicionalidad, supone una importante herramienta para determinar, en un futuro, posibiles pagos a los agricultores por el caracter multifuncional de este sistema productivo. Por ello, en el presente trabajo se plantea un cuestionario Delphi a una serie de expertos, con el objetivo de conocer su opinion sobre los impactos economicos, ambientales y sociales de explotaciones de olivar tradicional y marginal de secano, con una pendiete media mayor al 10% gestionadas en ecologico y convencional, en zonas de baja productividad -inferior a 1.500 kg aceitunas/ha-. Los resultados muestran la existencia de impactos en todos los aspectos considerados, por lo que, a pesar de la implementacion de la condicionalidad, la agricultura ecologica sigue ofreciendo un amplio conjunto de bienes y servicios ambientales y sociales al margen de la olivacultura convencional. The definition and assessment of organic olive farming's marginal effects after the implementation of Cross Compliance, emerges as an important tool in order to determine future payments to farmers because of the inherent multifunctionality of this production system. For this reason, in this paper a Delphi questionnaire is presented to a group of experts in order to know their opinion about the economic, environmental and social effects of organic and conventional rain fed olive groves, on sloping lands over 10% in low productivity areas (less than 1500 kg/ha). Results show the existence of impacts in every considered issue; so that, despite the implementation of Cross Compliance, organic olive farming continues to offer a wide joint of environmental and social goods and services, beyond conventional olive farming.

description: A femtosecond laser is a powerful tool for micromachining of silicon. In this work, large-area laser ablation of crystalline silicon is comprehensively studied using a laser source of pulse width 300 fs at two wavelengths of 343 nm and 1030 nm. We develop a unique approach to gain insight into the laser milling process by means of detailed analysis of trenches. Laser scribed trenches and milled areas are characterized using optical profilometry to extract dimensional and roughness parameters with accuracy and repeatability. In a first step, multiple measures of the trench including the average depth, the volume of recast material, the average longitudinal profile roughness, the inner trench width and the volume removal rate are studied. This allows for delineation of ablation regimes and associated characteristics allowing to determine the impact of fluence and repetition rate on laser milling. In a second step, additional factors of debris formation and material redeposition that come into play during laser milling are further elucidated. These results are utilized for processing large-area (up to few mm2) with milling depths up to 200 μm to enable the fabrication of cavities with low surface roughness at high removal rates of up to 6.9 μm3 μs-1. Finally, laser processing in combination with XeF2 etching is applied on SOI-CMOS technology in the fabrication of radio-frequency (RF) functions standing on suspended membranes. Performance is considerably improved on different functions like RF switch (23 dB improvement in 2nd harmonic), inductors (near doubling of Q-factor) and LNA (noise figure improvement of 0.1 dB) demonstrating the applicability of milling to radio-frequency applications.

description: El princciapl objetivo de este trabajo es el analisis del impacto sobre el mercado laboral pesquero andaluz en referencia a la flota pesquera afectada por la no renovacion del acuerdo de pesca entre la Union Europea y el Reino de Marruecos. En este sentido, se lleva a cabo un estudio de los determinantes de la duracion del desempleo para los pescadores andaluces que se vieron obligados a paralizar su actividad y perdieron su empleo tras la finalizacion del Acuerdo de pesca entre la Union Europea y el Reino de Marruecos el 30 de noviembre de 1999. Utilizando la metodologia de los modelos de riesgos en competencia se identifican los factores relevantes que afectan a la duracion del desempleo para cada una de las salidas consideradas. Para ello se distinguen como salidas alternativas los empleos en el Regimen Especial de Trabajadores del Mar y en un Regimen distinto a este por su importancia en la formulacion de medidas que favorezcan la reconversion o diversificacion de la actividad pesquera. The main objective of this work is to analyze the impact on the Andalusian fishing labour market in relation to the fishing fleet which was affected by the non-renewal of the fishing agreement between the European Union and Morocco. In this regard, we study the causes of unemployment duration for the Andalusian fisherman whose fishing activity finished when the Fishing Agreement between the European Union and Morocco expired on 30 November 1999. Using a competing risk model, we have identified the factors that influence the duration of the unemployment in the Sea Workers' Special Regime and the employment in a Regime which is different from this one, because of its importance in the suggestion of measures that benefits the restructuring or diversification of fishing activity.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. 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. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: We study the photoproduction of exclusive $2π^+2π^-$ mesons in ultra-peripheral heavy-ion collisions at RHIC and LHC energies. Predictions in photon-nucleus interactions are calculated for various resonances at central and forward rapidities. The recent H1 preliminary data are utilized to improve the description of the poorly known $γp \to 4π^\pm p$ process. We present the comparisons of our results to the available STAR data at RHIC, and made predictions for LHC energies.

description: Los signos de calidad son una estrategia muy utilizada en los paises del sur de Europa para promocionar productos con caracteristicas difernciales. Pero la enorme profusion de los signos realcionados con el origen esta provocando un efecto contrario al pretendido, ya que el mensaje que transmiten es cada vez menos claro para el consumidor. Entre las diferentes soluciones que emregen recientemente ante este problema, destacan las llamdas marcas de segunda generacion ligadas a procesos de desarrollo rural territorial. El objetivo de este articulo es presentar una metodologia original, elaborada especificamente para la evaluacion de estas marcas. El trabajo revisa los retos metodologicos que se han tenido que superar para abordar este tipo de evaluacion. La aplicacion empirica ha consistido en la validacion de la metodologia propuesta, al ser probada satisfactoriamente en una muestra de 15 territorios con marca de calidad territorial. Quality labelling is a strategy that is widely used in southern European countries to promote products with differential characteristics. However, the profusion of origin-related labels is causing the opposite effect as the message they convey is becoming increasingly less clear to consumers. The various solutions recently proposed to overcome this problem include what is know as second-generation labels linked to territorial rural development processes. In this paper we present an original methodology to evaluate these labels and review the methodological challenges in undertaking an evaluation of this type. The suitability of the methodology proposed has been empirically proved in a sample of fifteen territories involved in a territorial quality label joint project.

description: Objective: Although there is a considerable body of literature probing the knowledge and awareness of doctors of guidelines on medical fitness to drive, little is known of knowledge and awareness of such guidelines among the general public. We investigated awareness, perceptions and attitudes among a range of adults toward risk and personal responsibility in the context of medical fitness to drive. Methods: This quasi-experimental between groups study assessed response differences between healthcare (33%) and non-healthcare professionals. Five hundred and fourteen adults (f = 342) completed a 15-item online survey, which assessed their license status, direct and secondhand experience with key medical conditions, perceptions of risk, driving intentions if advised to stop driving by a doctor and beliefs about responsibility for ensuring driver fitness. Results: Most of the participants had a driver license. Although the majority (87%) had no first-hand experience with key medical conditions contained in the Irish medical fitness to drive guidelines, two-thirds knew someone with at least one of these conditions. No participant admitted to an alcohol or drug misuse/dependence problem. Alcohol misuse/dependence and fatigue/chronic sleep loss were perceived as the greatest crash risk for drivers and for vulnerable road users. Risk perceptions in general public and the medical professionals were similar for most conditions but where they differed, the medical professionals perceived lower risk. Most respondents indicated that they would cease driving immediately if advised by their doctor for temporary and long-term conditions. No effects of age, gender, experience with medical conditions or professional status were noted on perceived intentions to cease driving. Perceptions about who is responsible for ensuring people are fit to drive fell into two categories. Drivers were perceived as chiefly responsible where alcohol, non-prescription drugs, fatigue and age were factors and doctors were identified as responsible in cases of diabetes, epilepsy, stroke, heart conditions and physical disabilities. Conclusions: These results suggest that more needs to be done to raise awareness of the risks posed by medical and other factors that reduce driver capability and also about drivers’ responsibility to ensure that they are fit to drive and thus improve road safety.
