Dynamics of inequalities in geometric function theory

open access: yesJournal of Inequalities and Applications, 2001
A domain in the complex plane which is star-like with respect to a boundary point can be approximated by domains which are star-like with respect to interior points. This approximation process can be viewed dynamically as an evolution of the null points

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

open access: yesFEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

The density of extreme points in complex polynomial approximation [PDF]

open access: yes, 1988
Let K K be a compact set in the complex plane having connected and regular complement, and let f f be any function continuous on K K and analytic in the interior of K K .

Accuracy Examination of the Fourier Series Approximation for Almost Limiting Gravity Waves on Deep Water

open access: yesMathematical and Computational Applications
A permanent gravity wave propagating on deep water is a classic mathematical problem. However, the Fourier series approximation (FSA) based on the physical plane was examined to be valid for almost waves at all depths.

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Approximation by complex kantorovich-schurer polynomials in compact disks [PDF]

open access: yes, 2012
Bu tezde kompakt disklerde analitik fonksiyonlara ilişkin kompleks Bernstein- Schurer ve Kantorovich-Schurer polinomlarının yaklaşım özellikleri incelendi. Bu operatörler için eş anlı yaklaşım mertebesi ve Voronovskaja tip teoremler verildi.

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Analysis of a reaction-diffusion system of ƛ -w type [PDF]

open access: yes, 2003
The author studies two coupled reaction-diffusion equations of 'ƛ - w' type, on an open, bounded, convex domain Ω C R(^d) (d ≤ 3), with a boundary of class C(^2), and homogeneous Neumann boundary conditions.

A Two-Stage Numerical Algorithm for the Simultaneous Extraction of All Zeros of Meromorphic Functions

open access: yesAppliedMath
In this paper, we present an effective two-stage numerical algorithm for the simultaneous finding of all roots of meromorphic functions in a region within the complex plane. At the first stage, we construct a polynomial with the same roots as the ones of

Charef rational approximation of fractional operators and singular properties of novel scale equations

open access: yes四川大学学报. 自然科学版, 2022
According to the single-fraction power pole and zero model of the Charef rational approximation of the fraction operator, two new types of non-normal scaling equations-the novel scaling equation are introduced, which are used to characterize the limit ...
