Notas para la historia del castellano "rumor"
No parece necesitada la voz castellana "rumor" de un trabajo particular sobre su etimología -aunque consista sólo en unas notas tan modestas como las presentes-, dado que se trata de un vocablo del que se conoce su biografía: latinismo documentado desde el siglo XV. Tiene, sin embargo, esta palabra una historia más azarosa de lo que hemos supuesto lingüistas y filólogos.Does not seem that the castellana voice "rumor" has a particular task on its etymology. It is a word that is known in his biography: latinism documented since the fifteenth century. It has, however, a more eventful history that linguists and philologists have believed.notPeerReviewe
Dalle que dalle: la Filología como intermediaria en el salto de la cantidad a la calidad
construir un corpus textual con los recursos de la informática (es el caso del segundo firmante de este artículo) o esta posibilidad apenas había empezado a hacerse realidad en nuestra lengua (es el caso de la primera firmante), la idea básica que nos habían inculcado para el trabajo filológico se podía resumir así: si un grupo numeroso de textos de una misma familia recogía una determinada variante, ello no llevaba a premiar la cantidad frente a la calidad que supondría que otra variante apareciera solo en dos textos, pero de distinta familia; de forma que normalmente esta última forma ––la “lectio difficilior”― se consideraba preferente la primera. Saliendo fuera de las copias de un texto, para hacer una reconstrucción externa, era impensable ir más allá de donde llegó Alberto Blecua, con no poca paciencia, para tomar decisiones textuales con respecto a las poesías garcilasianas a través de aquellos testimonios que podían considerarse fuentes de las obras del poeta o, yendo en sentido inverso, siguiendo los rastros de las variantes discutidas, a través de las influencias que este ejerció
GEOGRAPHICAL VARIABILITY IN THE AMOUNT OF BIGEYE CAUGHT UNDER FADS BY PURSE SEINERS IN THE EASTERN ATLANTIC: FROM THE MULTISPECIES SAMPLES AND THE ICCAT STATISTICS
This paper analyses the geographical distribution of bigeye FAD catches by PS using results of
multispecies sampling of EU FAD catches (1991-2016). This analysis shows marked
geographical gradients in the geographical distribution of bigeye catches, catches being rare in
coastal areas and increasingly abundant at increasing distances from the shore. Opposite
changes are observed for yellowfin abundance, while skipjack abundance tends to be similar in
most areas. Yearly trends in relative abundances of bigeye and skipjack are also observed. These
observed species compositions are widely in contradiction with the species composition of Task
II data. This statistical problem in the bigeye geographical distribution is a source of errors in
the choice and analysis of FAD moratoria. It is also a source of potential error in the Task 1
bigeye catches. Based on fine scale sampled catches, bigeye catches by the Ghanaian fleet could
be widely overestimated today because of its improper data processing. Our study makes the
recommendation that improved Task II statistics should be prepared for the EU&al PS and for
the Ghanaian fleet before the bigeye stock assessment
Justo Alejo a Contrapelo de la Realidad
It is one thing that "Subspecie aeternitatis we are all, without exception, failures" and another that, in order to achieve this, some have to work harder than others. failures" and another that, in order to achieve it, some have to work harder than others. others. Justo Alejo managed to acquire this condition of failure without having to make too much effort. to make much of an effort. He had all the cards to achieve it and if he did not was not number one in his promotion, it is because the condition of cursed poet came before that of the the status of the accursed poet before that of the loser himself.Una cosa es que "Subspecie aeternitatis todos, sin excepción, s[ea]mos unos fracasados" y otra que, para lograrlo, unos tengan que esmerarse más que otros. Justo Alejo llegó a adquirir esta condición de fracasado sin tener que esforzarse demasiado. Contaba con todas las cartas para conseguirlo y si no fue el número uno en su promoción es porque se le adelantó la condición de poeta maldito a la del fracasado propiamente dicho
La relación entre los manuscritos 10 202 y 10 203 de la BNE, del "Árbol de las batallas"
The relationship between two manuscripts from the National Library of Spain which include the translation that Antón Zorita did by commission from the first Marquis of Santillana is examined. There are clear evidences that one of the manuscripts, which is supposed to be the final version, is directly based in the other. The more significant corrections between both texts are to do with an attempt of leaving out features characteristics from the "aragonés" dialect.; Analizamos en este trabajo la relación entre dos manuscritos de la Biblioteca Nacional de España, que contienen la traducción que hizo Antón Zorita del Arbre des batailles de H. Bovet por encargo del Marqués de Santillana. Hay claras evidencias de que uno de los manuscritos, que pretende ser la versión definitiva de la traducción, sigue directamente al otro. Las correcciones más significativas entre ambos códices están originadas por el intento de despojar la traducción de rasgos aragoneses
Preoperational Doppler-radar mesoscale wind structure detection algorithm: application to Spanish Mediterranean cases
Póster presentado en: 11th Plinius Conference on Mediterranean Storms celebrado en Barcelona del 7 al 11 de septiembre de 2009.Doppler radar information is used to identify features related to the radial wind field and signals such as mesovortex and other mesoscale wind structures. Automation of some processes can improve the forecasters’ ability to issue early warnings for hazardous

Optical determination of three-dimensional nanotrack profiles generated by single swift-heavy ion impacts in lithium niobate
Three-dimensional (3D) profiles of single nanotracks generated by a low impact density of Cl ions at 46 MeV have been determined by optical methods, using an effective-medium approach. The buried location of the maximum stopping power induces a surface optical waveguiding layer even at ultralow fluences (1011-1013 at./cm2) that allows to obtain the effective refractive index profiles (from dark-mode measurements). Combining the optical information with Rutherford backscattering spectroscopy/channeling experiments, the existence of a surrounding defective halo around the amorphous track core has been ascertained. The 3D profile of the halo has also been determined. © 2006 American Institute of Physics.Peer Reviewe

Two-state theory of nonlinear Stochastic Resonance
An amenable, analytical two-state description of the nonlinear population
dynamics of a noisy bistable system driven by a rectangular subthreshold signal
is put forward. Explicit expressions for the driven population dynamics, the
correlation function (its coherent and incoherent part), the signal-to-noise
ratio (SNR) and the Stochastic Resonance (SR) gain are obtained. Within a
suitably chosen range of parameter values this reduced description yields
anomalous SR-gains exceeding unity and, simultaneously, gives rise to a
non-monotonic behavior of the SNR vs. the noise strength. The analytical
results agree well with those obtained from numerical solutions of the Langevin
equation.Comment: 4 pages, 1 figur
Epistasis between cultural traits causes paradigm shifts in cultural evolution
Every now and then the cultural paradigm of a society changes. While current models of cultural shifts usually require a major exogenous or endogenous change, we propose that the mechanism underlying many paradigm shifts may just be an emergent feature of the inherent congruence among different cultural traits. We implement this idea through a population dynamics model in which individuals are defined by a vector of cultural traits that changes mainly through cultural contagion, biased by a 'cultural fitness' landscape, between contemporary individuals. Cultural traits reinforce or hinder each other (through a form of cultural epistasis) to prevent cognitive dissonance. Our main result is that abrupt paradigm shifts occur, in response to weak changes in the landscape, only in the presence of epistasis between cultural traits, and regardless of whether horizontal transmission is biased by homophily. A relevant consequence of this dynamics is the irreversible nature of paradigm shifts: the old paradigm cannot be restored even if the external changes are undone. Our model puts the phenomenon of paradigm shifts in cultural evolution in the same category as catastrophic shifts in ecology or phase transitions in physics, where minute causes lead to major collective changes.This work was supported by the Spanish projects VARIANCE (FIS2015-64349-P, MINECO/FEDER, UE),
