A Certain Subclass of Multivalent Functions Involving Higher-Order Derivatives
, 2016 In this paper we introduce and study a new class of analytic and $p$-valent functions involving higher-order derivatives. For this $p$-valent function class, we derive several interesting properties including (for example) coefficient inequalities ...

Argument estimates of meromorphically multivalent functions
Journal of Inequalities and Applications, 2000 The object of the present paper is to obtain some argument properties of meromorphically multivalent functions in the punctured open unit disk. We also derive the integral preserving properties in a sector.

New Criteria for Meromorphic Multivalent Alpha-Convex Functions
Journal of Applied Mathematics, 2013 The aim of the present paper is to obtain sufficient condition for the class of meromorphic p-valent alpha convex functions of order ξ and then to study mapping properties of the newly defined integral operators.

A note on multivalent functions
Proceedings of the Japan Academy, Series A, Mathematical Sciences, 1991 Let \(A_ p(n)\) be the class of functions of the form \(f(z)=z^ p+\sum^ \infty_{k=p+n}a_ kz^ k\) \((p\in \mathbb{N};\;n\in \mathbb{N})\) which are analytic in the open unit disk \(U=\{z:| z|

A certain family of meromorphically multivalent functions [PDF]
, 1999 By making use of a familiar analogue of the Ruscheweyh derivative as well as of the principle of subordination between two analytic functions, the authors introduce and study rather systematically a certain family of meromorphically multivalent functions

Smart Electrospun Nanofibers for Controlled Oil‐Water Separation
Advanced Materials Interfaces, EarlyView.Stimuli‐responsive electrospun nanofibers are reviewed as advanced platforms for controlled oil/water separation. The effects of surface wettability, porous structure, and external stimuli, including pH, temperature, gas, and light, on separation performance are discussed.

A criterion for multivalent functions
Proceedings of the Japan Academy, Series A, Mathematical Sciences, 1992 Let \(f(z)=z^ p+\sum^ \infty_{n=p+1} a_ n z^ n\) be analytic in the unit disc. A classical result for \(p=1\) is that \(\text{Re }f'(z)>0\) implies that \(f\) is univalent in the disc. Ozaki proved that for general \(p\), \(\text{Re }e^{i\alpha} f^{(p)}(z)>0\) implies that \(f\) is at most \(p\)-valent. This result was improved to show that \(\text{Re }

3D‐Printed Corneal Substitutes: Materials, Fabrication, and Preclinical Progress
Advanced Materials Technologies, EarlyView.Successful clinical translation of 3D‐printed corneal substitutes relies on the interplay between the bioink properties, cellular component, and the fabrication process. These factors influence the critical properties of the construct, including optical transparency, mechanical stability, suture retention, that ultimately govern long‐term stromal ...
