Log-concavity property for some well-known distributions [PDF]
Surveys in Mathematics and its Applications, 2011 Interesting properties and propositions, in many branches of science such as economics have been obtained according to the property of cumulative distribution function of a random variable as a concave function.

Inequalities for some basic hypergeometric functions
Проблемы анализа, 2019 We establish conditions for the discrete versions of logarithmic concavity and convexity of the higher order regularized basic hypergeometric functions with respect to the simultaneous shift of all its parameters.

Inequalities of extended beta and extended hypergeometric functions
Journal of Inequalities and Applications, 2017 We study the log-convexity of the extended beta functions. As a consequence, we establish Turán-type inequalities. The monotonicity, log-convexity, log-concavity of extended hypergeometric functions are deduced by using the inequalities on extended beta ...

Sand Rubber Mixtures under Oedometric Loading: Sand-like vs. Rubber-like Behavior
Applied Sciences, 2023 Each year, the number of scrap tires disposed of in huge piles across the world continuously increases. Consequently, new recycling solutions for these materials have to be proposed.

Sampling from Log-Concave Distributions
The Annals of Applied Probability, 1994 The authors present an algorithm for efficient sampling from a probability distribution on \(\mathbb{R}^ n\) with log-concave density \(F\), where \(F\), or at least a sufficiently close approximation \(\overline F\) of \(F\), is known. The sampling is restricted to a compact convex set \(K\) such that the integral of \(F\) over \(K\) is sufficiently ...

Mean Field Approximations via Log-Concavity
International Mathematics Research Notices, 2023 Abstract We propose a new approach to deriving quantitative mean field approximations for any probability measure $P$ on $\mathbb {R}^{n}$ with density proportional to $e^{f(x)}$, for $f$ strongly concave. We bound the mean field approximation for the log partition function $\log \int e^{f(x)}dx$ in terms of $\sum _{i \neq j}\mathbb {E}_{

Jumping to Hasty Experience Curves
Annals of Business Administrative Science, 2013 The “experience curve” used to be treated as a rule of thumb in strategic management theory. However, it would be hasty to conclude that an approximately 80% log-linear experience curve is a rule of thumb regardless of the industry, company, or product ...

The log-concavity of the q-derangement numbers of type B
Open Mathematics, 2018 Recently, Chen and Xia proved that for n ≥ 6, the q-derangement numbers Dn(q) are log-concave except for the last term when n is even. In this paper, employing a recurrence relation for DnB(q) $\begin{array}{} \displaystyle D^B_n(q) \end{array ...
