Classes of multivalent functions associated with a convolution operator [PDF]

, 2010
We investigate several properties of the linear Aouf–Silverman–Srivastava operator and associated classes of multivalent analytic functions which were introduced and studied by Aouf et al. [M.K. Aouf, H. Silverman, H.M.

Subordination Properties for Multivalent Functions Associated with a Generalized Fractional Differintegral Operator

Axioms, 2018
Using of the principle of subordination, we investigate some subordination and convolution properties for classes of multivalent functions under certain assumptions on the parameters involved, which are defined by a generalized fractional differintegral ...

Switching Spike Plasticity Shapes ACE2 Engagement Across SARS-CoV-2 Variants. [PDF]

Adv Sci (Weinh)
Conformational plasticity governs SARS‐CoV‐2 spike function and ACE2 recognition. Using high‐speed AFM and single‐molecule force spectroscopy, we analyzed the ancestral spike and nine variants, revealing progressive rigidification from Delta, variable plasticity in Omicron sublineages, and JN.1 compaction.

The Comprehensive Live Cell‐Based Cytotoxicity Assay for Monitoring Disease Activity and Guiding Rescue Therapy in Acute Attacks of NMOSD

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neuromyelitis optica spectrum disorder (NMOSD) is a devastating neurological disease that lacks serological biomarkers that can accurately reflect disease activity. We established a live cell‐based assay (LCBA) using serum with endogenous complement to quantify the overall cytotoxicity, offering a novel functional tool for monitoring

Some Marx-Strohhacker type results for a class of multivalent functions

, 2017
In this paper, two Marx-Strohhäcker type results are proven for a certain class of analytic and multivalent functions in the open unit disk D. The first result gives the order of multivalent starlikeness for multivalently convex functions of some ...

On an Identity Related to Multivalent Functions [PDF]

Proceedings of the American Mathematical Society, 1995
In 1948 A. W. Goodman conjectured that if \(f(z)= \sum_{i=1}^ \infty b_ n z^ n\) is regular and \(p\)-valent in the unit disc \(E= \{z\): \(| z|< 1\}\) then \[ | b_ n|\leq \sum_{k=1}^ p D(p,k, n)| b_ k|, \qquad 1\leq k\leq ...
