Analytic properties and numerical representations for constructing the extended beta function using logarithmic mean

open access: yesAIMS Mathematics
This paper aimed to obtain generalizations of both the logarithmic mean ($ \text{L}_{mean} $) and the Euler's beta function (EBF), which we call the extended logarithmic mean ($ \text{EL}_{mean} $) and the extended Euler's beta-logarithmic function ...

Obstacle Mean-Field Game Problem [PDF]

open access: yes, 2014
In this paper, we introduce and study a first-order mean-field game obstacle problem. We examine the case of local dependence on the measure under assumptions that include both the logarithmic case and power-like nonlinearities.

ATP13A2 is involved in intracellular polyamine transport in lung epithelial cells

open access: yesFEBS Open Bio, EarlyView.
Spermidine transport in lung epithelial cells involves the polyamine transporter ATP13A2. Cell proliferation is associated with the upregulation of ATP13A2. Polyamines are present in all living cells and are implicated in various crucial cellular processes such as proliferation, apoptosis and autophagy.

Ostrowski type inequalities involving conformable fractional integrals

open access: yesJournal of Inequalities and Applications, 2018
In the article, we establish several Ostrowski type inequalities involving the conformable fractional integrals. As applications, we find new inequalities for the arithmetic and generalized logarithmic means.

On the logarithmic mean of accretive matrices

open access: yesFilomat, 2019
In this paper, we define the logarithmic mean of two accretive matrices and study its basic properties. Among other results, we show that if A; B are accretive matrices, then RL(A,B) ?

Brownian motion at absolute zero

open access: yes, 2005
We derive a general quantum formula giving the mean-square displacement of a diffusing particle as a function of time. Near {\bf 0 K} we find a universal logarithmic behavior (valid for times longer than the relaxation time), and deviations from ...

Optimal Generalized Logarithmic Mean Bounds for the Geometric Combination of Arithmetic and Harmonic Means [PDF]

open access: yes, 2011
In this paper, we answer the question: for 2 (0; 1), what are thegreatest value p = p() and least value q = q(), such that the double inequalityLp(a; b) A(a; b)H1(a; b) Lq(a; b) holds for all a; b > 0?

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Phase transition of a two dimensional binary spreading model

open access: yes, 2002
We investigated the phase transition behavior of a binary spreading process in two dimensions for different particle diffusion strengths ($D$). We found that $N>2$ cluster mean-field approximations must be considered to get consistent singular behavior ...
