Universal portfolios generated by rational functions [PDF]

open access: yesITM Web of Conferences, 2021
The f -divergence of Csiszar is defined for a non-negative convex function on the positive axis. A pseudo f -divergence can be defined for a convex function not satisfying the usual requirements.

Inequalities for Jensen–Sharma–Mittal and Jeffreys–Sharma–Mittal Type f–Divergences

open access: yesEntropy, 2021
In this paper, we introduce new divergences called Jensen–Sharma–Mittal and Jeffreys–Sharma–Mittal in relation to convex functions. Some theorems, which give the lower and upper bounds for two new introduced divergences, are provided.

Majorization inequalities via Green functions and Fink’s identity with applications to Shannon entropy

open access: yesJournal of Inequalities and Applications, 2020
This paper is devoted to obtain generalized results related to majorization-type inequalities by using well-known Fink’s identity and new types of Green functions, introduced by Mehmood et al. (J. Inequal. Appl. 2017:108, 2017).

Some inequalities for Csiszár divergence via theory of time scales

open access: yesAdvances in Difference Equations, 2020
In this paper, we present some inequalities for Csiszár f-divergence between two probability measures on time scale. These results extend some known results in the literature and offer new results in h-discrete calculus and quantum calculus.

Difference equations related to majorization theorems via Montgomery identity and Green’s functions with application to the Shannon entropy

open access: yesAdvances in Difference Equations, 2020
In this paper we give generalized results of a majorization inequality by using extension of the Montgomery identity and newly defined Green’s functions (Mehmood et al. in J. Inequal. Appl. 2017(1):108, 2017). We obtain a generalized majorization theorem

Majorization, Csiszár divergence and Zipf-Mandelbrot law

open access: yesJournal of Inequalities and Applications, 2017
In this paper we show how the Shannon entropy is connected to the theory of majorization. They are both linked to the measure of disorder in a system. However, the theory of majorization usually gives stronger criteria than the entropic inequalities.

Zipf–Mandelbrot law, f-divergences and the Jensen-type interpolating inequalities

open access: yesJournal of Inequalities and Applications, 2018
Motivated by the method of interpolating inequalities that makes use of the improved Jensen-type inequalities, in this paper we integrate this approach with the well known Zipf–Mandelbrot law applied to various types of f-divergences and distances, such ...

Diosgenin Alleviates Age‐Related Sarcopenia by Promoting Satellite Cell Proliferation and Myogenic Differentiation via Activation of the SIRT1/PGC‐1α Signaling Pathway

open access: yesAging Cell, Volume 25, Issue 8, August 2026.
As a critical bioactive component of Polygonatum sibiricum, diosgenin improves age‐related declines in skeletal muscle mass and function by activating the SIRT1/PGC‐1α pathway, upregulating the expression of the myokine METRNL and IGF‐1, and promoting satellite cell proliferation and myogenic differentiation.
