A Catalan triangle

Discrete Mathematics, 1976
AbstractWe develop an arithmetic triangle similar to Pascal's triangle. The entries are interpreted in terms of numbers of pairs of nonintersecting paths in the first quadrant. The main applications are results about the Catalan numbers and various random walk problems.

EDA Complex‐Driven Desaturation of Heterocyclic Carbonyl Compounds Enabled by HFIP

Angewandte Chemie, EarlyView.
In this work, we report a novel light‐mediated desaturation strategy enabled by electron donor–acceptor complex formation. DFT and mechanistic studies reveal that the reaction proceeds via single‐electron transfer, hydrogen atom transfer, and base‐mediated deprotonation sequentially with pyridinium salt serving dually as oxidant and base, and ...

The catalan industry.

Treballs de la Societat Catalana de Geografia, 1986
As it is generally known, Catalonia is the main industrial area in Spain. In l983 Catalonia generated 25.7% of the Spanish industry V.A.T. and assembled 24.5% of the employed industrial labour force. None of the other industrial areas or the country reached half or the Catalan production: Madrid ( 12.2% of the industrial V.A.T.). Basc Country (10.8% of

Emergent Magnetic Structures at the 2D Limit of the Altermagnet MnTe

Advanced Functional Materials, EarlyView.
Renewed interest in MnTe has emerged due to its intriguing altermagnetism, a newly identified form of magnetism distinct from conventional ferro‐, antiferro‐, or paramagnetism. By combining magnetic X‐ray absorption spectroscopy, scanning tunnelling microscopy, and first‐principles theory, this study reveals that thinning MnTe to the 2D limit ...

Paris vu par Terenci Moix : un étranger au paradis ? (Étude du troisième tome de ses mémoires Extraño en el paraíso)

Cahiers d’Études Romanes, 2001
Tout comme le suggère le titre du troisième tome des mémoires de Terenci Moix, Extraño en el paraiso (Etranger au paradis), Paris est la ville de tous les espoirs pour le jeune Catalan qui arrive dans la capitale de la France alors que l’Espagne vit sous

Novel 3D‐Printed Biophotonic Scaffold Displaying Luminescence under Near‐Infrared Light for Photopharmacological Activation and Biological Signaling Compound Release

Advanced Healthcare Materials, EarlyView.
Despite significant efforts in developing novel biomaterials to regenerate tissue, only a few of them have successfully reached clinical use. It has become clear that the next generation of biomaterials must be multifunctional. Smart biomaterials can respond to environmental or external stimuli, interact in a spatial‐temporal manner, and trigger ...

SPANISH IN CATALONIA (Conditional Languages and exalted nationalism)

Ибероамериканские тетради, 2016
For the last decades the coexistence of Spanish and Catalan has experienced an identity crisis, a clash between the languages that is not apparent in other ambilingual territories or other Catalan-speaking regions. This paper will show the reasons behind

Chromatic statistics for Catalan and Fuß-Catalan numbers

Electronic Journal of Combinatorics, 2011
We refine Catalan numbers and Fuß-Catalan numbers by introducing colour statistics for triangulations of polygons and $d$-dimensional generalisations there-of which we call Fuß-Catalan complexes. Our refinements consist in showing that the number of triangulations, respectively Fuß-Catalan complexes, with a given colour distribution of its vertices is ...
