Series associated with harmonic numbers, Fibonacci numbers and central binomial coefficients $binom{2n}{n}$ [PDF]
We find various series that involve the central binomial coefficients $binom{2n}{n}$, harmonic numbers and Fibonacci numbers. Contrary to the traditional hypergeometric function _pF_q approach, our method utilizes a straightforward transformation to ...

The NADPH oxidase NOX4 regulates redox and metabolic homeostasis preventing HCC progression
Loss of NOX4 in HCC tumor cells induces metabolic reprogramming in a Nrf2/MYC‐dependent manner to promote HCC progression. Abstract Background and Aims The NADPH oxidase NOX4 plays a tumor‐suppressor function in HCC. Silencing NOX4 confers higher proliferative and migratory capacity to HCC cells and increases their in vivo tumorigenic potential in ...

Spoken and Written Representation of Number in L2 Catalan Indefinite Determiner Phrases [PDF]
The study explores the relationship that second language (L2) learners of Catalan establish between the spoken and the written representation of number inflection within an indefinite-article Determiner Phrase (DP); and it also addresses first language ...

Simplifying coefficients in differential equations for generating function of Catalan numbers
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 ...

On a new congruence in the Catalan triangle [PDF]
For 0≤k≤n, the number C(n,k) represents the number of all lattice paths in the plane from the point (0,0) to the point (n,k), using steps (1,0) and (0,1), that never rise above the main diagonal y = x.
