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

J Mass Spectrom
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,

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 ...

Subordinations and Norm Estimates for Functions Associated with Ma-Minda Subclasses

Mathematics, 2022
For a function p analytic in the open unit disc and satisfying p(0)=1, we prove certain subordination implications of the first order differential subordination 1+zp′(z)≺1+Mz, which provides sufficient conditions for a function to belong to various ...

Norm Estimates of the Pre-Schwarzian Derivatives for Functions with Conic-like Domains

Mathematics, 2023
The pre-Schwarzianand Schwarzian derivatives of analytic functions f are defined in U, where U is the open unit disk. The pre-Schwarzian as well as Schwarzian derivatives are popular tools for studying the geometric properties of analytic mappings. These

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 ...

Radius Results for Certain Strongly Starlike Functions

Symmetry, 2023
This article comprises the study of strongly starlike functions which are defined by using the concept of subordination. The function φ defined by φ(ζ)=(1+ζ)λ, 0<λ<1 maps the open unit disk in the complex plane to a domain symmetric with respect to the real axis in the right-half plane.

Vertical Dependency of Aerosol Impacts on Local Scale Convective Precipitation

Geophysical Research Letters, Volume 50, Issue 2, 28 January 2023., 2023
Abstract Aerosol effects on convective precipitation is critical for understanding human impacts on extreme weather and the hydrological cycle. However, even their signs and magnitude remain debatable. In particular, aerosol effects on vertical structure of precipitation have not been systematically examined yet. Combining 6‐year space‐borne and ground‐
