British Stereo Photographers in Spain: Frank M. Good

Unlike French stereographers, who flooded the market with Spanish views, the most important British publishers and photographers rarely made Spanish views. Quite possibly this was precisely because of the rapid market penetration of the French, such as Gaudin, Ferrier and others, and in spite of the leading British photographic houses, such as Frith or George W. Wilson, also wanting to include Spanish views in their catalogues. The photographer Frank Good would be the only British photographic editor to make a collection of some importance of Spanish stereoscopic views during the first decades of the history of photography, visiting and photographing the cities of San Sebastian, Zaragoza, Barcelona, Tarragona, Valencia, Seville and Cordoba. About one hundred views, of which more than half are of Cordoba and Seville, do not include, strangely, cities such as Madrid, Toledo and Granada

The averaging trick and the Cerny conjecture

The results of several papers concerning the \v{C}ern\'y conjecture are deduced as consequences of a simple idea that I call the averaging trick. This idea is implicitly used in the literature, but no attempt was made to formalize the proof scheme axiomatically. Instead, authors axiomatized classes of automata to which it applies

Enantioselective Biocascade Catalysis with a Single Multifunctional Enzyme

Asymmetric catalytic cascade processes offer direct access to complex chiral molecules from simple substrates and in a single step. In biocatalysis, cascades are generally designed by combining multiple enzymes, each catalyzing individual steps of a sequence. Herein, we report a different strategy for biocascades based on a single multifunctional enzyme that can promote multiple stereoselective steps of a domino process by mastering distinct catalytic mechanisms of substrate activation in a sequential way. Specifically, we have used an engineered 4-oxalocrotonate tautomerase (4-OT) enzyme with the ability to form both enamines and iminium ions and combine their mechanisms of catalysis in a complex sequence. This approach allowed us to activate aldehydes and enals toward the synthesis of enantiopure cyclohexene carbaldehydes. The multifunctional 4-OT enzymes could promote both a two-component reaction and a triple cascade characterized by different mechanisms and activation sequences

Factorizing complementation in a TT-MCTAG for German

TT-MCTAG lets one abstract away from the relative order of co-complements in the final derived tree, which is more appropriate than classic TAG when dealing with flexible word order in German. In this paper, we present the analyses for sentential complements, i.e., wh-extraction, thatcomplementation and bridging, and we work out the crucial differences between these and respective accounts in XTAG (for English) and V-TAG (for German)

Developing a TT-MCTAG for German with an RCG-based parser

Developing linguistic resources, in particular grammars, is known to be a complex task in itself, because of (amongst others) redundancy and consistency issues. Furthermore some languages can reveal themselves hard to describe because of specific characteristics, e.g. the free word order in German. In this context, we present (i) a framework allowing to describe tree-based grammars, and (ii) an actual fragment of a core multicomponent tree-adjoining grammar with tree tuples (TT-MCTAG) for German developed using this framework. This framework combines a metagrammar compiler and a parser based on range concatenation grammar (RCG) to respectively check the consistency and the correction of the grammar. The German grammar being developed within this framework already deals with a wide range of scrambling and extraction phenomena

New records of alien vascular plants in Catalonia (NE Iberian Peninsula)

Altres ajuts: "Proyecto Intramural Especial, PIE" (grant no. 201630I024) from the CSICNew records of alien vascular plants in Catalonia (NE Iberian Peninsula).- We provide the first records of five non-native vascular plants for Europe-Commelina erecta, Cylindropuntia fulgida, Dasylirion serratifolium, ×Graptosedum and Senecio crassissimus, two for the Iberian Peninsula-Lobelia laxiflora subsp. angustifolia and Pennisetum flaccidum, and four for Catalonia- Dimorphotheca fruticosa, ×Gasteraloe beguinii, Opuntia elatior and Tradescantia sillamontana. In addition, new local records are provided for ten taxa scarcely reported for Catalonia. During the last decades, ornamental horticulture constitutes the most important source of alien plants, and some of them are potentially invasive species at a worldwide level. Most of the plants listed in this study are escaped from gardens or established as a consequence of dumping green waste. Some species are locally naturalized and in some cases they could behave as invasive.Nuevas citas de plantas vasculares alóctonas en Cataluña (NE de la Península Ibérica).- Aportamos citas de cinco plantas alóctonas nuevas para Europa -Commelina erecta, Cylindropuntia fulgida, Dasylirion serratifolium, ×Graptosedum y Senecio crassissimus-, dos nuevas para la península ibérica -Lobelia laxiflora subsp. angustifolia y Pennisetum flaccidum- y cuatro nuevas para Cataluña -Dimorphotheca fruticosa, ×Gasteraloe beguinii, Opuntia elatior y Tradescantia sillamontana-. También presentamos nuevos datos sobre diez plantas poco citadas en Cataluña. En las últimas décadas el cultivo de plantas ornamentales constituye la principal causa de introducción de especies alóctonas a escala mundial, algunas de las cuales son potencialmente invasoras. La mayoría de las plantas que constan en este trabajo son escapadas de cultivos o provienen de vertidos de restos de jardinería. Algunas especies se encuentran localmente naturalizadas y en algún caso podrían presentar un comportamiento invasor
