The peculiar behavior of dnaA, gyrA and gyrB temperature-sensitive mutants and their Hfr derivatives made recA, rnhA or both mutants

open access: yesJournal of Biological Research, 2018
The role of the recA and rnhA mutations on the growth of different thermo-sensitive mutants at the non permissive temperature was studied. The growth of Hfr strains selected by integrative suppression in a dnaA(Ts) mutant was found strongly dependent on ...

Topological invariants for semigroups of holomorphic self-maps of the unit disc [PDF]

open access: yes, 2015
Let $(\varphi_t)$, $(\phi_t)$ be two one-parameter semigroups of holomorphic self-maps of the unit disc $\mathbb D\subset \mathbb C$. Let $f:\mathbb D \to \mathbb D$ be a homeomorphism.

Value Ranges of Univalent Self-Mappings of the Unit Disc [PDF]

open access: yes, 2015
We describe the value set $\{f(z_0)\,:\, f:\mathbb{D}\to\mathbb{D} \text{ univalent}, f(0)=0, f'(0)= e^{-T} \},$ where $\mathbb{D}$ denotes the unit disc and $z_0\in\mathbb{D}\setminus\{0\}$, $T>0,$ by applying Pontryagin's maximum principle to the ...

The Characterization of Schwarz theorem and unit discs

open access: yesCommunications, Faculty Of Science, University of Ankara Series A1Mathematics and Statistics, 1994
Summary: Let \(\overline D= \{z\in\mathbb{C}:|z|\leq r\}\) be a set and \(A(\overline D)\) be an algebra of bounded analytic functions on \(\overline D\). In this paper, taking complex algebra \(R\), we gave the characterization of the Schwarz theorem. In the special case \(r=1\), we obtain the characterization of Schwarz lemma.

The Patellar Resurfacing in Total Knee Prosthesis: Indications for Bone Stock and Patellar Morphology

open access: yesFrontiers in Medicine, 2021
The patellar resurfacing is still a controversial and unresolved problem. The choice to use the patellar resurfacing in the total knee prosthesis (TKP) is decided by the surgeon's experience; he analyzes the thickness, the shape, consumption of the ...
