A generalization of the Becker model in linear viscoelasticity: Creep, relaxation and internal friction

open access: yes, 2018
We present a new rheological model depending on a real parameter $\nu \in [0,1]$ that reduces to the Maxwell body for $\nu=0$ and to the Becker body for $\nu=1$.

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Majorization problems for two subclasses of analytic functions connected with the Liu–Owa integral operator and exponential function

open access: yesJournal of Inequalities and Applications, 2018
In the present paper, we investigate majorization properties for the class Mβα(p,γ) $M_{\beta}^{\alpha}(p,\gamma)$ of uniformly starlike functions and the class Nβα(p,θ) $N_{\beta}^{\alpha}(p,\theta)$ of spiral-like functions related to an exponential ...

Semi-Hyers-Ulam-Rassias stability for an integro-differential equation of order 𝓃

open access: yesDemonstratio Mathematica, 2023
The Laplace transform method is applied in this article to study the semi-Hyers-Ulam-Rassias stability of a Volterra integro-differential equation of order n, with convolution-type kernel.

A concentration theorem for the equilibrium measure of Markov chains with nonnegative coarse Ricci curvature [PDF]

open access: yes, 2012
A nonnegative coarse Ricci curvature for a Markov chain and the existence of an attractive point implies the concentration of the invariant probability measure around this point.

Discrete complementary exponential and sine integral functions

open access: yesDemonstratio Mathematica, 2023
AbstractDiscrete analogues of the sine integral and complementary exponential integral functions are investigated. Hypergeometric representation, power series, and Laplace transforms are derived for each. The difficulties in extending these definitions to other common trigonometric integral functions are discussed.

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Validity and error analysis of calculating matrix exponential function and vector product

open access: yesNonlinear Engineering
In this study, an efficient calculation method of matrix exponential function and vector product is proposed to reduce the calculation error. This method is based on the flexible exponential integral scheme; using B-series theory and two-color tree ...

On weighted exponential-Gompertz distribution: properties and application

open access: yesJournal of Taibah University for Science, 2019
In this paper, we introduce a new distribution generated by an integral transform of the probability density function of the weighted exponential distribution. This distribution is called the weighted exponential-Gompertz (WE-G). Its hazard rate function

Sums of Powers and Special Polynomials

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2020
In this paper, we discuss sums of powers 1p + 2p + + np and compute both the exponential and ordinary generating functions for these sums. We express these generating functions in terms of exponential and geometric polynomials and also show their ...
