Differential inequalities for spirallike and strongly starlike functions [PDF]

Advances in Difference Equations, 2021
AbstractIn this paper, by using a technique of the first-order differential subordination, we find several sufficient conditions for an analytic function p such that $p(0)=1$ p ( 0 ) = 1 to satisfy $\operatorname{Re}\{ {\mathrm{e}

Label‐Free Molecular Characterization of Protein Aggregates in Differentiated Astrocytes

Advanced Science, Volume 13, Issue 16, 18 March 2026.
Mid‐infrared photothermal microscopy enables label‐free structural, molecular, and functional imaging of protein aggregates in astrocyte cells. The processes of astrocytes differentiated on a nanomaterial interface are characterized by α‐helical signatures combined with enhanced interfacial thermal resistance properties, while the cell soma of non ...

Starlikeness associated with certain strongly functions

Heliyon
Let κ be an analytic function in the open unit disc U in the complex plane with κ ( 0 ) = 1 . Then κ ∈ K ( λ ) if and only if κ ( t ) ≺ ϕ λ ( t ) , where ≺ is a subordination relation and the function ϕ λ ( t ) : = ( 1 + t ) λ , for 0 < λ < 1 , maps U to a symmetric domain about the real axis in the right-half plane.

Quantitative Analysis of Polymers by MALDI‐TOF Mass Spectrometry: Correlation Between Signal Intensity and Arm Number.

Journal of Mass Spectrometry, Volume 61, Issue 1, January 2026.
ABSTRACT The signal intensities of linear and star‐shaped poly(L‐lactides) (PLA) and poly (ethylene oxides) (PEO) were compared to determine the influence of the number of arms on the ionization in matrix‐assisted laser desorption/ionization time‐of‐flight (MALDI‐TOF) mass spectrometry. In this study, a variety of blends were prepared and investigated,

On Logarithmic and Inverse Coefficients for Sakaguchi‐Type Starlike Functions Subordinated to a Petal‐Shaped Domain

Journal of Function Spaces, Volume 2026, Issue 1, 2026.
In this paper, we study several important coefficient problems for the class Sp∗ of Sakaguchi‐type starlike functions subordinated to a petal‐shaped domain. We obtain a collection of sharp bounds that extend and refine known results in geometric function theory.

Starlike Functions With Respect to a Boundary Point Connected With Bounded Radius Rotation

Journal of Function Spaces, Volume 2026, Issue 1, 2026.
In the current article, we introduce a new subclass of univalent function Gμ with bounded radius rotation. For this new class, the authors establish many interesting relations between these classes and existing classes. Furthermore, authors try to find coefficient estimations for this new subclass.

Straightforward Preparation of Polyurethane‐Based Biomaterials with Dual Antibacterial and Anti‐Adhesive Properties for Long‐Lasting Catheter Applications

Advanced Materials Interfaces, Volume 12, Issue 24, December 22, 2025.
This study presents the elaboration of antibacterial, antiadhesive, and antibiofilm polyurethane by a straightforward process based on the co‐extrusion of 2 wt.% of both antibacterial and antiadhesive copolymer. The material proves to be active even after pre‐exposition to biological media and prevents E. coli biofilm formation without toxicity.
