Catalan, a threatened language? The linguistic vitality of Catalan according to Catalan youth
Llengua, societat i comunicacióRecent sociolinguistic data in Catalonia demonstrates a general decline in the social use of Catalan, with a particular decrease among young speakers in public schools who are increasingly favoring Spanish. Despite decades of institutional and grassroots support, as well as an increase of speakers in absolute terms, the future of Catalan continues to ...

Light‐Modulated Exchange Bias in Multiferroic Heterostructures
Electron, EarlyView.In this article, exchange bias and magnetization are modulated with visible light at room temperature in PMN‐PZT/FeGa/IrMn multiferroic heterostructures. Photostrictive effect is the main mechanism leading to the modulation of magnetic anisotropy and interfacial exchange bias coupling between the ferromagnetic and antiferromagnetic layers.

Epilepsia, EarlyView.Abstract Objective Neonatal developmental and epileptic encephalopathy with movement disorder and arthrogryposis (NDEEMA) represents the most severe end of the gain‐of‐function (GOF) SCN1A disorder spectrum. Sporadic cases of congenital arthrogryposis have also been reported in individuals with SCN2A‐, SCN3A‐, and SCN8A‐related developmental and ...

Catalan numbers, q-Catalan numbers and hypergeometric series
Journal of Combinatorial Theory, Series A, 1987 The author derives a new \(q\)-analog of the Catalan numbers: \[ {\mathcal C}_ n(\lambda,q)=q^{2n}\prod \frac{1+\lambda q^{2i-3}}{1-q^{2i}},\quad 1\leq i\leq n. \] The usual Catalan numbers are given by \({\mathcal C}_ n={\mathcal C}_ n(-1,1)\). In addition to this representation as a rational function in \(q\), Andrews' \(q\)-Catalan numbers have a ...

Cardiovascular disease incidence and cancer risk in two large European prospective cohorts
International Journal of Cancer, EarlyView.What's New? Cardiovascular disease (CVD) and cancer share risk factors and biological mechanisms, raising questions about potential associations between the two, particularly regarding CVD duration and cancer onset. Whether CVD influences subsequent cancer risk, however, remains inconclusive.

International Journal of Cancer, EarlyView.Over a dozen cancers have been associated with excess body mass index, primarily in mid‐to‐late adulthood. Whether obesity‐related cancer risk differs across adulthood remains unclear. Using the Sensitive Periods Model and super‐landmarking approaches, this study found that higher BMI increased obesity‐related cancer risk across ages 30–65.

On generalised catalan numbers
Discrete Mathematics, 1978 AbstractThe Catalan number Cn is defined to be 2nn(n+1). One of its occurrences is as the number of ways of bracketing a product of n+1 terms taken from a set with binary operation. In this note the corresponding result for a set with a k-ary operation is considered.

International Journal of Cancer, EarlyView.Limited evidence links processed meat intake and non‐cardia gastric cancer, while esophageal adenocarcinoma is increasing in Western countries, where diets are typically high in red and processed meats. Using data from over 450,000 participants from a large prospective study, the authors examined meat consumption and the risk of gastric and esophageal ...
