Boron-Locked Starazine - A Soluble and Fluorescent Analogue of Starphene. [PDF]
Chemistry, 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 ...

On Some Subclasses of Strongly Starlike Analytic Functions
International Journal of Analysis and Applications, 2020 The aim of the present article is to investigate a family of univalent analytic functions on the unit disc $D$ defined for $M \geq 1$ by $$\Re (\frac{zf'(z)}{f(z)}) > 0, |(\frac{zf'(z)}{f(z)})^2 - M|<M, z \in D.$$ Some proprieties, radius of ...

Quantitative Analysis of Polymers by MALDI-TOF Mass Spectrometry: Correlation Between Signal Intensity and Arm Number. [PDF]
J Mass SpectromABSTRACT 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,

Ruscheweyh derivative and strongly starlike functions
Tsukuba Journal of Mathematics, 2000 The class \(\overline{S}^*(\beta,\gamma)\) of strongly starlike functions of order \(\beta\) and type \(\gamma\) consists of functions \(f(z) = \sum_{k=1}^\infty a_k z^k\) which are analytic in the unit disc and satisfy \(|\arg (zf'(z)/f(z) - \gamma)|< \pi \beta /2\) for all \(z\) in the unit disc. Here \(0 \leq \gamma < 1\) and \(0 < \beta < 1\). (The

Label-Free Molecular Characterization of Protein Aggregates in Differentiated Astrocytes. [PDF]
Adv Sci (Weinh)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. [PDF]
HeliyonLet 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.

SOME CRITERIA FOR STARLIKENESS AND STRONGLY STARLIKENESS [PDF]
Bulletin of the Korean Mathematical Society, 2005 The authors discuss on certain sufficient conditions for starlikeness and strongly starlikeness of analytic functions in the unit disk. Their results generalise and refine known results of \textit{J.-L. Li} and \textit{S. Owa} [Indian J. Pure Math. 33, 313--318 (2002; Zbl 0998.30010), Georgian Math. J. 5, 361--366 (1998; Zbl 0924.30008)] and of \textit{

Strongly Starlike Functions and Related Classes
Tamkang Journal of Mathematics, 2021 We consider univalent functions, analytic in the unit disc $ |z|<1$in the complex plane ${\mathbb{C}}$ which map $ |z|<1$ onto a domainwith some nice property. The purpose of this paper is to find somenew conditions for strong starlikeness and some related results.

Shape‐Morphing Photoresponsive Hydrogels Reveal Dynamic Topographical Conditioning of Fibroblasts
Advanced Science, Volume 10, Issue 31, November 3, 2023., 2023 This study presents a cell‐compatible hydrogel‐based platform that allows reconfiguration of the topography of the cellular environment on demand using illumination. It demonstrates that fibroblasts sense the dynamic topographies and suggest that cells are capable of “remembering” previous topographies via the formation of focal adhesion complexes on ...
