Certain Geometric Study Involving the Barnes–Mittag-Leffler Function

Fractal and Fractional
The main purpose of this paper is to study certain geometric properties of a class of analytic functions involving the Barnes–Mittag-Leffler function. The main mathematical tools are the monotonicity patterns of some class of functions associated with ...

Coding and anticoding of a cardinal by bounded subsets of the cardinal

Journal of the London Mathematical Society, Volume 113, Issue 3, March 2026.
Abstract This paper will consider combinatorial properties related to coding a cardinal by its bounded subsets. These properties have traditionally been studied in the context of very large cardinals and variations of these properties either reach the level of Kunen inconsistency or are very close to it.

Robust Model‐Based Semi‐Supervised Clustering of Incomplete Records

Statistical Analysis and Data Mining: An ASA Data Science Journal, Volume 19, Issue 1, February 2026.
ABSTRACT This paper develops a multivariate t$$ t $$‐mixture model‐based semi‐supervised clustering methodology for datasets with incomplete records. Specifically, we consider the case where not all features are always observed, as well as the case where label information for some of the records is available, where the interest is in grouping all of ...

Impact of Grain Size on Low‐Temperature Carrier Phase Coherence Length in Polycrystalline Halide Perovskite Films

Advanced Materials Interfaces, Volume 13, Issue 1, 7 January 2026.
Magnetoresistance measurements on a series of polycrystalline cesium tin iodide (CsSnI3) thin film devices having varying grain sizes reveal no power law dependence with clear signatures of weak anti‐localization (spin‐orbit coupling). Surprisingly, the extracted phase coherence lengths are found to be independent of grain sizes.

New Sharp Bounds for Gamma and Digamma Functions

Annals of the Alexandru Ioan Cuza University - Mathematics, 2011
Inspired by the recent paper giving the two-sided Stirling-like sharp estimates of the factorial, the author uses this result to obtain bounds for gamma and digamma functions. To do this he constructs a completely monotonic function \(f\) containing a gamma function and some other functions and constants related to the bounds of the above estimates of \

Atomic‐Scale Epitaxy for Tailoring Crystalline GeSbTe Alloys Into Bidimensional Phases

Advanced Materials Interfaces, Volume 13, Issue 1, 7 January 2026.
This Study Shows How Molecular Beam Epitaxy Can Precisely Control the Growth of Ge–Sb–Te Alloys By Tuning Temperature and Elemental Flux Ratio. A Predictive Growth Diagram is established, Linking Structural Ordering to Electrical Transport, and Enabling Efficient, low‐power Switching in Memory Devices.

Closed-form estimators for the inverse Nakagami distribution

Anais da Academia Brasileira de Ciências
The inverse Nakagami distribution due to Louzada et al. (2018) does not have closed-form maximum likelihood estimators. Closed-form estimators by adapting the method of moments are proposed in this note.

Qi’s conjectures on completely monotonic degrees of remainders of asymptotic formulas of di- and trigamma functions

Journal of Inequalities and Applications, 2020
Several conjectures posed by Qi on completely monotonic degrees of remainders for the asymptotic formulas of the digamma and trigamma functions are proved.

Interval‐valued Caputo–Fabrizio fractional derivative in continuous programming

Asian Journal of Control, Volume 28, Issue 1, Page 497-514, January 2026.
Abstract This study investigates a novel class of variational programming problems characterized by fractional interval values, formulated under the Caputo–Fabrizio fractional derivative with an exponential kernel. Invex and generalized invex functions are used to discuss the Mond–Weir‐type dual problem for the considered variational problem.

From OPE to chiral perturbation theory in holographic QCD

EPJ Web of Conferences, 2016
The soft wall model in holographic QCD has Regge trajectories but wrong operator product expansion (OPE) for the two-point vectorial QCD Green function. We modify the dilaton potential to comply with the OPE.
