Criteria for a certain class of the Carathéodory functions and their applications

Journal of Inequalities and Applications, 2020
In this paper, we obtain some potentially useful conditions (or criteria) for the Carathéodory functions as a certain class of analytic functions by applying Nunokawa’s lemma.

Mechanically Mutable Matrices: A Hierarchical Investigation of Decellularized Sea Cucumber Collagen as an Adaptable Scaffold Material

Advanced Functional Materials, EarlyView.
Sea cucumber mutable collagenous tissue (MCT) is a remarkable collagen‐based material which can rapidly undergo large changes in stiffness through transiently bound effector proteins. Here, we investigate the hierarchical structure and mechanical response of MCT from Cucumaria frondosa across length scales with a wide range of methods, also exploring ...

On Some Problems of Strongly Ozaki Close-to-Convex Functions

Journal of Function Spaces, 2020
The purpose of the current paper is to investigate some geometric properties of the class FOν,γ, called strongly Ozaki close-to-convex functions, such as strongly starlikeness and close-to-convexity.

LOGARITHMIC COEFFICIENTS OF SOME CLOSE-TO-CONVEX FUNCTIONS [PDF]

Bulletin of the Australian Mathematical Society, 2016
The logarithmic coefficients$\unicode[STIX]{x1D6FE}_{n}$of an analytic and univalent function$f$in the unit disc$\mathbb{D}=\{z\in \mathbb{C}:|z|<1\}$with the normalisation$f(0)=0=f^{\prime }(0)-1$are defined by$\log (f(z)/z)=2\sum _{n=1}^{\infty }\unicode[STIX]{x1D6FE}_{n}z^{n}$.

Charge Generation and Recombination Pathways in All‐Polymer Bulk Heterojunction Solar Cells

Advanced Functional Materials, EarlyView.
Multimodal spectroscopy and device analysis reveal how field‐dependent charge generation, transport limitations, and non‐geminate recombination govern performance losses in all polymer solar cells. The results identify the key processes controlling charge extraction and recombination, providing insights for the design of more efficient all‐polymer ...

A new subclass of close-to-convex functions [PDF]

Surveys in Mathematics and its Applications, 2016
In this work, we introduce and investigate an interesting subclass Xt(γ) of analytic and close-to-convex functions in the open unit disk U. For functions belonging to the class Xt(γ), we drive several properties including coefficient estimates ...
