Functions of bounded variation, the derivative of the one dimensional maximal function, and applications to inequalities [PDF]

open access: yes, 2006
We prove that if f: I ⊂ R→ R is of bounded variation, then the uncentered maximal function Mf is absolutely continuous, and its derivative satisfies the sharp inequality ∥DMf∥ L 1(I) < |Df|(I). This allows us to obtain, under less regularity, versions of

The Sharp Bounds of the Third-Order Hankel Determinant for Certain Analytic Functions Associated with an Eight-Shaped Domain

open access: yesFractal and Fractional, 2022
The main focus of this research is to solve certain coefficient-related problems for analytic functions that are subordinated to a unique trigonometric function.

ON A COMPREHENSIVE CLASS OF ANALYTIC P-VALENT FUNCTIONS ASSOCIATED WITH SHELL-LIKE CURVE AND MODIFIED SIGMOID FUNCTION

open access: yesMalaysian Journal of Computing, 2022
In this paper, the authors introduce and study a new class of analytic p-valent functions and its connections with some famous subclasses of analytic and univalent functions associated with shell-like curve and modified sigmoid function in the open unit ...

On functions with bounded remainder [PDF]

open access: yesAnnales de l’institut Fourier, 1989
Let T: \({\mathbb{R}}/{\mathbb{Z}}\to {\mathbb{R}}/{\mathbb{Z}}\) be a von Neumann-Kakutani q- adic adding machine transformation and let \(\phi \in C^ 1([0,1])\). Put \[ \phi_ n(x):=\phi (x)+\phi (Tx)+...+\phi (T^{n-1}x),\quad x\in {\mathbb{R}}/{\mathbb{Z}},\quad n\in {\mathbb{N}}. \] We study three questions: 1.

Slice Holomorphic Functions in Several Variables with Bounded L-Index in Direction

open access: yesAxioms, 2019
In this paper, for a given direction b ∈ C n \ { 0 } we investigate slice entire functions of several complex variables, i.e., we consider functions which are entire on a complex line { z 0 + t b : t ∈ C } for any z

Research on Bounded Rationality of Fuzzy Choice Functions

open access: yesThe Scientific World Journal, 2014
The rationality of a fuzzy choice function is a hot research topic in the study of fuzzy choice functions. In this paper, two common fuzzy sets are studied and analyzed in the framework of the Banerjee choice function.

Between Droughts and Floods: The Seasonal Response of Freshwater Snails in Artificial Reservoirs in the Brazilian Semiarid Region

open access: yesPopulation Ecology, EarlyView.
We investigate the seasonal dynamics of two freshwater snails, Biomphalaria straminea and Melanoides tuberculata, in artificial reservoirs of the Brazilian semiarid region. Despite regulated hydrology, B. straminea exhibited strong seasonal fluctuations associated with dry periods, while M. tuberculata maintained stable populations throughout the year,

The cytoskeletal control of B cell receptor and integrin signaling in normal B cells and chronic lymphocytic leukemia

open access: yesFEBS Letters, EarlyView.
In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.

Approximation Algorithms for Complex-Valued Ising Models on Bounded Degree Graphs [PDF]

open access: yesQuantum, 2019
We study the problem of approximating the Ising model partition function with complex parameters on bounded degree graphs. We establish a deterministic polynomial-time approximation scheme for the partition function when the interactions and external ...
