Champagne subregions of the unit disc [PDF]

Proceedings of the American Mathematical Society, 2011
This paper concerns harmonic measure on the domains that arise when infinitely many disjoint closed discs are removed from the unit disc. It investigates which configurations of discs are unavoidable for Brownian motion, and obtains refinements of ...

Centralizers of non-elliptic univalent self-maps and the embeddability problem in the unit disc [PDF]

Transactions of the American Mathematical Society, 2023
The embeddability problem is a very old and hard problem in discrete holomorphic iteration which deals with determining general conditions on a given univalent self-map

Hausdorff Operators on Some Spaces of Holomorphic Functions on the Unit Disc [PDF]

Complex Analysis and Operator Theory, 2021
We introduce Hausdorff operators over the unit disc and give conditions for boundedness of such operator in Bloch, Bergman, and Hardy spaces on the disc. Approximation of the identity by Hausdorff operators is also considered.

On Geometric Properties of Bessel–Struve Kernel Functions in Unit Disc

Mathematics, 2022
The Bessel–Struve kernel function defined in the unit disc is used in this study. The Bessel–Struve kernel functions are generalized in this article, and differential equations are derived.

Application of Einstein Function on Bi-Univalent Functions Defined on the Unit Disc

Symmetry, 2022
Motivated by q-calculus, we define a new family of Σ, which is the family of bi-univalent analytic functions in the open unit disc U that is related to the Einstein function E(z). We establish estimates for the first two Taylor–Maclaurin coefficients |a2|

Asymptotic monotonicity of the orthogonal speed and rate of convergence for semigroups of holomorphic self-maps of the unit disc [PDF]

Revista matemática iberoamericana, 2020
We show that the orthogonal speed of semigroups of holomorphic self-maps of the unit disc is asymptotically monotone in most cases. Such a theorem allows to generalize previous results of D. Betsakos and D. Betsakos, M. D. Contreras and S.

Semigroup-fication of univalent self-maps of the unit disc [PDF]

Annales de l'Institut Fourier, 2020
Let $f$ be a univalent self-map of the unit disc. We introduce a technique, that we call {\sl semigroup-fication}, which allows to construct a continuous semigroup $(\phi_t)$ of holomorphic self-maps of the unit disc whose time one map $\phi_1$ is, in a ...

The fading guardian: clinical relevance of TP53 null mutation in high-grade serous ovarian cancers

Frontiers in Immunology, 2023
Backgroundwe evaluated the concordance between immunohistochemical p53 staining and TP53 mutations in a series of HGSOC. Moreover, we searched for prognostic differences between p53 overexpression and null expression groups.Methodspatients affected by ...

Molecular Epidemiological Investigation of a Nosocomial Cluster of C. auris: Evidence of Recent Emergence in Italy and Ease of Transmission during the COVID-19 Pandemic

Journal of Fungi, 2021
Candida auris is an emerging MDR pathogen raising major concerns worldwide. In Italy, it was first and only identified in July 2019 in our hospital (San Martino Hospital, Genoa), where infection or colonization cases have been increasingly recognized ...

Spread of Carbapenem-Resistant Gram-Negatives and Candida auris during the COVID-19 Pandemic in Critically Ill Patients: One Step Back in Antimicrobial Stewardship?

Microorganisms, 2021
The possible negative impact of severe adult respiratory distress caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection (COVID-19) on antimicrobial stewardship and infection control has been postulated, but few real-life data ...
