On Strongly Starlike Functions Related to the Bernoulli Lemniscate

Tamkang Journal of Mathematics, 2022
Let $\mathcal{S}^{\ast}_{L}(\lambda)$ be the class of functions $f$, analytic in the unit disc $\Delta=\{z:|z|<1\}$, with the normalization $f(0)=f'(0)-1=0$, which satisfy the condition\begin{equation*}\frac{zf'(z)}{f(z)}\prec \left(1+z\right)^{\lambda},\end{equation*}where $\prec$ is the subordination relation.

Chemical Approaches to Synthetic Drug Delivery Systems for Systemic Applications

Angewandte Chemie International Edition, Volume 61, Issue 49, December 5, 2022., 2022
Over 100 years after Paul Ehrlich's vision of the “magic bullet”, the major challenges in drug delivery remain unchanged: 1) controlling pharmacokinetic and biodistribution drug distribution and clearance in the blood; 2) solubilizing hydrophobic agents, and 3) selectively targeting specific tissues. This Review describes new alternatives for synthetic

Seasonality shapes community structure and functional group dynamics of zooplankton in Changjiang River estuary and its adjacent waters

Diversity and Distributions, Volume 28, Issue 10, Page 2152-2170, October 2022., 2022
Abstract Aim Functional trait‐based approach links the zooplankton community to the marine ecosystem functioning. It provides a comprehensive insight into the diversity of zooplankton ecological strategies but has rarely been used to characterize the zooplankton community in estuarine ecosystem.

Criteria for Strongly Starlike Functions [PDF]

ISRN Geometry, 2011
Let f(z) be analytic in the unit disk U={z:|z|<1} with f(0)=f'(0)-1=0 and (f(z)/z)f'(z)≠0. By using the method of differential subordinations, we determine the largest number α(β,λ,μ,m) such that, for some β,λ,μ, and m, the differential subordination λzf'(z)/f(z)1-μ1+(zf''(z)/f'(z))-zf'(z)/f(z)+zf'(z)/f(z)m≺1+z/1-zα(β,λ,μ,m)(z∈U) implies zf'(z)/f(z)≺

Boron‐Locked Starazine – A Soluble and Fluorescent Analogue of Starphene

Chemistry – A European Journal, Volume 28, Issue 29, May 19, 2022., 2022
The first counterpart of starphene, namely starazine, that contains a nonaaza‐core structure and three peripheral isoquinoline units locked by three tetracoordinate borons to form a quasi‐planar backbone is described. This starazine possesses a non‐aromatic and electron‐deficient core due to the introduction of the heteroatoms replacing the ...

Impacts of tillage and nutrient management on soil porosity trends in dryland agriculture

European Journal of Soil Science, Volume 73, Issue 1, January–February 2022., 2022
Abstract In dryland Mediterranean semi‐arid areas, the use of slurries and no‐till are encouraged to reduce costs. This paper evaluates the effect of such practices in terms of morphological changes of the topsoil porosity. The experiment had seven fertilization strategies (five of them including pig slurries applied at cereal sowing or at tillering ...

The Third Logarithmic Coefficient for Certain Close‐to‐Convex Functions

Journal of Mathematics, Volume 2022, Issue 1, 2022., 2022
The logarithmic coefficients γn of a normalized analytic functions f are defined by log fz/z=2∑n=1∞γnzn. For certain close‐to‐convex functions f(z) = z + a2z2 + ⋯, Cho et al. (on the third logarithmic coefficient in some subclasses of close‐to‐convex functions) has obtained the upper bound of the third logarithmic coefficient γ3 when the second ...

The Order of Strongly Starlikeness of the Generalized α-Convex Functions [PDF]

Symmetry, 2019
We consider the order of the strongly-starlikeness of the generalized α -convex functions. Some sufficient conditions for functions to be p-valently strongly-starlike are given.

Strongly starlike and spirallike functions [PDF]

Annales Polonici Mathematici, 2005
The author studies the concepts of strong starlikeness and spirallikeness with respect to a finite point as well as with respect to infinity. He also considers the meromorphic strongly starlike and meromorphic spirallike functions of order \((\alpha,\beta)\). New method of proofs are presented.
