The paper introduces a new family of analytic bi-univalent functions that are injective and possess inverses, by employing q-analogue the derivative operator. Moreover, article establishes upper bounds Taylor–Maclaurin coefficients these functions, which can aid in approximating accuracy approximations using finite number terms. obtained Faber polynomial expansions. These apply to both initial ...

The zero-truncated Poisson distribution is an important and appropriate model for many real-world applications. Here, we exploit the probabilities to construct a new subclass of analytic bi-univalent functions involving Gegenbauer polynomials. For in constructed class, explore estimates Taylor–Maclaurin coefficients a2 a3, next, solve Fekete–Szegő functional problem. A number interesting result...

Clostridial and spinach ferredoxins, reduced enzymatically by the action of ferredoxin-TPN+ oxidoreductase, have been shown to carry out the univalent reduction of oxygen. The superoxide radicals, so generated, were detected by their ability to cause the oxidation of epinephrine to adrenochrome. Superoxide dismutase prevented the production of adrenochrome in these reaction mixtures, while havi...
