Cancer and Traditional Plant Knowledge, an Interesting Field to Explore: Data from the Catalan Linguistic Area

open access: yesMolecules, 2022
Cancer is the second cause of death in the world and is foreseen to be responsible for about 16 million deaths in 2040. Approximately, 60% of the drugs used to treat cancer are of natural origin.

Factors Affecting Pronunciation Accuracy in English as a Foreign Language: The Case of Spanish-Catalan Intermediate Learners

open access: yesAtlantis. Journal of the Spanish Association for Anglo-American Studies, 2022
In the present study, we investigate the factors that influence pronunciation accuracy by Spanish-Catalan bilinguals learning English as a foreign language (EFL).

The Problem of Separatism in Modern Spain: the Catalan Question

open access: yesПроблемы постсоветского пространства, 2022
Catalan nationalism, rooted in the 19th century, transformed into separatism in the 1980s, threatening the existence of the Spanish state. The unstable political situation in the country caused by the crisis of the party system and serious economic ...

Prevalence norms for 40,777 Catalan words: An online megastudy of vocabulary size

open access: yesBehavior Research Methods, 2022
In this study, we present word prevalence data (i.e., the number of people who know a given word) for 40,777 Catalan words. An online massive visual lexical decision task involving more than 200,000 native speakers of this language was carried out.

Chromatic statistics for Catalan and Fuß-Catalan numbers

open access: yesElectronic 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 ...

On the $H$-triangle of generalised nonnesting partitions [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2014
With a crystallographic root system $\Phi$ , there are associated two Catalan objects, the set of nonnesting partitions $NN(\Phi)$, and the cluster complex $\Delta (\Phi)$. These possess a number of enumerative coincidences, many of which are captured in

Catalan pairs: A relational-theoretic approach to Catalan numbers

open access: yesAdvances in Applied Mathematics, 2010
AbstractWe define the notion of a Catalan pair (which is a pair of binary relations (S,R) satisfying certain axioms) with the aim of giving a common language to several combinatorial interpretations of Catalan numbers. We show, in particular, that the second component R uniquely determines the pair, and we give a characterization of R in terms of ...

Simplifying coefficients in differential equations for generating function of Catalan numbers

open access: yesJournal of Taibah University for Science, 2019
In the paper, by the Faà di Bruno formula, several identities for the Bell polynomials of the second kind, and an inversion theorem, the authors simplify coefficients in two families of nonlinear ordinary differential equations for the generating ...

Logarithmically complete monotonicity of a function related to the Catalan-Qi function

open access: yesActa Universitatis Sapientiae: Mathematica, 2016
In the paper, the authors find necessary and sufficient conditions such that a function related to the Catalan-Qi function, which is an alternative generalization of the Catalan numbers, is logarithmically complete monotonic.

Integral Representations of the Catalan Numbers and Their Applications

open access: yesMathematics, 2017
In the paper, the authors survey integral representations of the Catalan numbers and the Catalan–Qi function, discuss equivalent relations between these integral representations, supply alternative and new proofs of several integral representations ...
