On a Non-Newtonian Calculus of Variations

open access: yesAxioms, 2021
The calculus of variations is a field of mathematical analysis born in 1687 with Newton’s problem of minimal resistance, which is concerned with the maxima or minima of integral functionals.

Multiplicative Concavity of the Integral of Multiplicatively Concave Functions [PDF]

open access: yesJournal of Inequalities and Applications, 2010
A real-valued function \(f:I\subseteq {\mathbb R} \rightarrow (0,\infty)\) is said to be multiplicatively convex if \[ f(x^{1/2}y^{1/2}) \leq f^{1/2}(x)f^{1/2}(y) \] for all \(x,y \in I\). And \(f\) is called multiplicatively concave if \(1/f\) is multiplicatively convex. Multiplicatively convexity on \(E\subseteq {\mathbb R}_+^2\) is defined similarly.

Euler’s integrals and multiple sine functions [PDF]

open access: yesProceedings of the American Mathematical Society, 2004
We show that Euler’s famous integrals whose integrands contain the logarithm of the sine function are expressed via multiple sine functions.

The Multiple Gamma-Functions and the Log-Gamma Integrals [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2012
In this paper, which is a companion paper to [W], starting from the Euler integral which appears in a generalization of Jensen’s formula, we shall give a closed form for the integral of log . This enables us to locate the genesis of two new functions and considered by Srivastava and Choi. We consider the closely related functionA(a)and the Hurwitz zeta

A type of multiple integral with log-gamma function [PDF]

open access: yesInvolve, a Journal of Mathematics, 2015
In this paper, we study the multiple integral $ \displaystyle I= \int_0^1 \int_0^1 \dots \int_0^1 f(x_1+x_2 + \dots +x_n) \, dx_1 \, dx_2 \, \dots \, dx_n$. A general formula of $I$ is presented. As an application, the integral $I$ with $f(x)= \log Γ(x)$ is evaluated. We show that the values of $I$ share a common formula for all $n \in \mathbb{N}$. The

Jackson's integral of multiple Hurwitz–Lerch zeta functions and multiple gamma functions [PDF]

open access: yesJournal of Mathematical Analysis and Applications, 2018
Using the Jackson integral, we obtain the $q$-integral analogue of the Raabe type formulas for Barnes multiple Hurwitz-Lerch zeta functions and Barnes and Vardi's multiple gamma functions. Our results generalize $q$-integral analogue of the Raabe type formulas for the Hurwitz zeta functions and log gamma functions in [N. Kurokawa, K.

Multiple Functions of Rad9 for Preserving Genomic Integrity [PDF]

open access: yesCurrent Genomics, 2006
DNA-damage checkpoints sense and respond to genomic damage. Human Rad9 (hRad9), an evolutionarily conserved gene with multiple functions for preserving genomic integrity, plays multiple roles in fundamental biological processes, including the regulation of the DNA damage response, cell cycle checkpoint control, DNA repair, apoptosis, transcriptional ...

Integrating multiple networks for protein function prediction [PDF]

open access: yesBMC Systems Biology, 2015
High throughput techniques produce multiple functional association networks. Integrating these networks can enhance the accuracy of protein function prediction. Many algorithms have been introduced to generate a composite network, which is obtained as a weighted sum of individual networks.

The hypocretins/orexins: integrators of multiple physiological functions [PDF]

open access: yesBritish Journal of Pharmacology, 2013
The hypocretins (Hcrts), also known as orexins, are two peptides derived from a single precursor produced in the posterior lateral hypothalamus. Over the past decade, the orexin system has been associated with numerous physiological functions, including sleep/arousal, energy homeostasis, endocrine, visceral functions and pathological states, such as ...

Functional integral approach for multiplicative stochastic processes [PDF]

open access: yesPhysical Review E, 2010
We present a functional formalism to derive a generating functional for correlation functions of a multiplicative stochastic process represented by a Langevin equation. We deduce a path integral over a set of fermionic and bosonic variables without performing any time discretization.
