Jazykové zákony v Katalánsku a jejich vliv na zlepšení postavení katalánštiny ve společnosti | Language legislation in Catalonia and its influence on the enhancement of the social status of Catalan [PDF]
Časopis pro Moderní Filologii, 2018 This paper introduces Catalonia, an autonomous community of Spain, located on the north-eastern extremity of the Iberian Peninsula. The focus is partly on the demography and the linguistic situation of this territory, but primarily on its linguistic ...

Immunomodulation of the Prostate Tumor Microenvironment Following Inorganic Arsenic Exposure
Journal of Applied Toxicology, EarlyView.ABSTRACT The tumor microenvironment (TME) influences prostate cancer (PCa) progression through stromal and immune interactions. Adipose‐derived mesenchymal stromal cells (ASCs) modulate immune tone, while inorganic arsenic (iAs), a widespread toxicant, is linked to immune suppression and carcinogenesis.

Catalan-like Numbers and Determinants
Journal of Combinatorial Theory, Series A, 1999 The Catalan numbers play a central role in enumerations. They can be defined by recursion but also via so-called Hankel matrices. The Motzkin numbers are defined by a very similar recursion, and Aigner also found a description using Hankel matrices. Both types of numbers are involved in several classical formulae with binomial coefficients (and with ...

Tableau Cycling and Catalan Numbers
, 2007 We develop two combinatorial proofs of the fact that certain Young tableaux are counted by the Catalan numbers. The setting is a larger class of tableaux where labels increase along rows without attention to whether labels increase down columns. We define a new operation called tableau cycling. It is used to duplicate the reflection argument attributed

Journal of Clinical Psychology, EarlyView.ABSTRACT Background and Hypothesis Ultra high risk (UHR) for psychosis can have different clinical trajectories but the remission rates are only 51.9% after 3 years of follow‐up. Deficits in metacognition are associated with severity of symptoms and poor response to treatment.

Catalan Numbers for the Classroom?
Elemente der Mathematik, 1997 The author describes the experiences with 13-14 years old pupils in a project on Catalan numbers. She asserts that solving simple combinatorial problems plays an important role in developing thought processes, and should be practised throughout secondary school.

Astragalus ecomorphology in Quaternary elephantids
Journal of Quaternary Science, EarlyView.ABSTRACT The astragalus plays a fundamental role in the graviportal locomotion of proboscideans, reflecting the biomechanical constraints imposed by large body masses. This study analyses the morphological variability of the astragalus in Quaternary elephantids using linear biometry and 3D geometric morphometrics, incorporating an unpublished ...

Limiting the Number of Possible CFG Derivative Trees During Grammar Induction with Catalan Numbers
MathematicsGrammar induction runs into a serious problem due to the exponential growth of the number of possible derivation trees as sentence length increases, which makes unsupervised parsing both computationally demanding and highly indeterminate.
