Results on bi-univalent functions [PDF]

open access: yes, 1981
When the class σ \sigma of bi-univalent functions was first defined, it was known that functions of the form ϕ ∘ ψ − 1 ∈

A Unifying Thermodynamic Model for Phase Separation and Aging of Biopolymers

open access: yesAdvanced Science, EarlyView.
Phase separation and aging of intrinsically disordered proteins are placed in a unifying framework. A thermodynamically consistent time‐dependent version of associating‐polymer theory shows how the processes are intricately coupled. Assuming aging to occur through interacting sites resulting from reversible conformational transitions, the model ...

Virus‐Mediated Self‐Assembly of Functional Cyclodextrins for Antiviral Inhibition

open access: yesAngewandte Chemie, EarlyView.
A sialic acid (SA)‐functionalized cyclodextrin (CD) self‐assembles on SARS‐CoV‐2 through ligand–receptor recognition, nucleating cooperative supramolecular polymer growth that blocks infection. The adaptive assembly requires both ligand binding and host–guest polymerization, remains active across variants, and can be tuned by coassembly, establishing ...

Some Properties of a Subclass Involving Close - to - Convex of Univalent and Multivalent Functions

open access: yesWasit Journal for Pure Sciences
Our work included studying some subclasses of functions (univalent - multivalent) that are close to convex. which is divide into two parts. First part, we discussed the properties of parameter estimates, the implication relation, distortion theorem, and

Coefficient problem for certain subclasses of bi-univalent functions defined by convolution [PDF]

open access: yesMathematica Moravica, 2016
In this paper, we consider a general subclass HλΣ (h, β) of bi-univalent functions. Bounds on the first two coefficients اa2ا and اa3ا for functions in HλΣ (h, β) are given. The main results generalize and improve a recent one obtained by Srivastava [18].

On the subclass of regular univalent functions [PDF]

open access: yes, 1987
In this thesis, we prove the results due to R.J. Libera and A. E. Livingston concerning the subclasses of regular, univalent functions such as class of starlike functions, class of convex functions and class of close-to-convex functions. Further, we show

On the coefficients of concave univalent functions [PDF]

open access: yes, 2020
Let D denote the open unit disc and f : D → ℂ̄ be meromorphic and injective in D. We assume that f is holomorphic at zero and has the expansion f(z) = z + ∞σ anzn Especially, we consider f that map D onto a domain whose complement with respect to ℂ̄ is ...

Single‐Atom‐Enhanced Fully Inkjet‐Printed Electrochemical Sensor for Dopamine Detection

open access: yesAdvanced Science, EarlyView.
Fully inkjet‐printed paper‐based dopamine sensors are fabricated using nitrogen‐doped graphene acid functionalized with copper single atoms. The copper sites uniquely enhance dopamine oxidation through strong molecular adsorption, as verified by electrochemical measurements and DFT calculations. The approach highlights the potential of single‐atom inks

Unraveling G‐Quadruplex and i‐Motif Coexistence Within a Double‐Stranded DNA

open access: yesAngewandte Chemie, EarlyView.
The relative thermodynamic profiles of G‐quadruplex (G4), i‐Motif (iM), and the duplex counterpart tune the simultaneous G4 and iM formation within a double‐stranded (ds) DNA. ABSTRACT DNA can transiently fold into variable arrangements, which are expected to exploit regulatory functions. Guanine‐rich sequences can fold into G‐quadruplexes (G4s), while

Environmental Effects on RRAM Cells Based on 2D Halide Perovskite Materials

open access: yesAdvanced Electronic Materials, EarlyView.
RRAM offers high speed, scalability, and low power, positioning it as a next‐generation non‐volatile memory. Two‐dimensional halide perovskites show promise due to tunable optoelectronic properties and flexible processing but suffer from environmental sensitivity. This review examines degradation from humidity, temperature, light, and strain, discusses
