Beyond the Tail: Taming Bias in Burr XII Residual Entropy Estimation

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.
Accurately predicting system lifetime is routine in reliability and survival analysis, but quantifying uncertainty in residual life is rarely addressed despite being often more critical. Residual entropy fills this gap by measuring unpredictability in remaining lifetime.

Non-linear least squares fit of specific heat data within the Schotte–Schotte model using web page

open access: yes, 2019
Specific heat of rare-earth based materials at low temperatures can often be described by the Schotte–Schotte model for Kondo impurity. For several decades thousands of papers have been published which were devoted to physics of rare-earth based ...

A Generalization of Ramanujan‐Type Integrals

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.
Recently, Xu, Yin, and Zhou obtained explicit evaluations of the Ramanujan‐type integrals ∫0∞xs−1sinbx/coshax−cosbxdx and ∫0∞xs−1sinbx/coshax+cosbxdx, expressing them in closed form in terms of the gamma function, the Riemann zeta function, and the alternating zeta function.

Fractional Whittaker Functions via a Fractional Kummer Equation

open access: yesJournal of Function Spaces, Volume 2026, Issue 1, 2026.
We develop a fractional analogue of the regular Whittaker function through a fractional Kummer equation constructed from the Caputo derivative and the associated fractional Euler operator Θα=xαCD0+α,01<α≤. The resulting fractional‐power series is governed by the sequence qnα=Γαn+1/Γαn−1+1,n≥10,q0α≔,which determines the coefficient recurrence ...

Properties of modified Bessel functions and completely monotonic degrees of differences between exponential and trigamma functions [PDF]

open access: yesMathematical Inequalities & Applications, 2015
In the paper, the author establishes inequalities, monotonicity, convexity, and unimodality for functions concerning the modified Bessel functions of the first kind and compute the completely monotonic degrees of differences between the exponential and trigamma functions.

Habitat heterogeneity and food availability in beaver‐engineered streams foster bat richness, activity and feeding

open access: yesJournal of Animal Ecology, Volume 94, Issue 12, Page 2403-2420, December 2025.
Beavers reshape ecosystems in ways that benefit bat richness, activity and feeding activity. We linked increased habitat structures (standing deadwood and canopy heterogeneity) and prey abundance to higher bat activity. Our findings uncover how beavers drive biodiversity across aquatic‐terrestrial boundaries.

Harmonic Growth—The Harmonic Number Applied to ROI, Business Scaling, Nth Plant Economics, Micro Combined Heat and Power (mCHP), Biorefineries, and Biochar Production

open access: yesMathematical Methods in the Applied Sciences, Volume 48, Issue 15, Page 13999-14013, October 2025.
ABSTRACT Scaling is a topic of utmost importance in business. When to scale and how has been the subject of countless books and seminars. This paper looks at modular businesses that have income and costs directly proportional to the number of units.
