Some New Bounds for Bateman’s G-Function in Terms of the Digamma Function [PDF]

In this paper, we present some new symmetric bounds for Bateman’s G-function and its derivatives, in terms of the digamma and polygamma functions, which are better than some recent ...

Omnibus goodness‐of‐fit tests for univariate continuous distributions based on trigonometric moments

Statistica Neerlandica, Volume 80, Issue 2, May 2026.
ABSTRACT We propose a new omnibus goodness‐of‐fit test based on trigonometric moments of probability‐integral‐transformed data. The test builds on the framework of the LK test introduced by Langholz and Kronmal [J. Amer. Statist. Assoc. 86 (1991), 1077–1084], but fully exploits the covariance structure of the associated trigonometric statistics.

Progression‐Free Survival 2 as a Potential Surrogate for Overall Survival in Glioblastoma: Insights From a Spanish Multicentric Cohort

Cancer Medicine, Volume 15, Issue 4, April 2026.
Overall, PFS2 correlated more strongly with OS than PFS (0.83 vs. 0.69). PFS2 outperformed PFS in patients with targetable alterations and in those without. Our findings support using PFS2 as a candidate surrogate endpoint in glioblastoma trials. Implementing PFS2 balances trial feasibility with clinical relevance of outcomes.

A Completely Monotonic Function Involving Divided Difference of Psi Function and an Equivalent Inequality Involving Sum [PDF]

, 2006
In this paper, a function involving the divided difference of the psi function is proved to be completely monotonic, a class of inequalities involving sum are founded, and an equivalent relation between the complete monotonicity and one of the class ...

Bi‐Directional Recurrent Attentional Topic Model Using Flexible Priors

Computational Intelligence, Volume 42, Issue 2, April 2026.
ABSTRACT This article presents extensions to the Bi‐Directional Recurrent Attentional Topic Model (bi‐RATM) framework, a Dirichlet‐based model used in text document analysis. The allocation of topics to a sentence in a document is determined by its content as well as the topics of its neighboring sentences, and the weighting is typically variable. Many

A modular relation involving a generalized digamma function and asymptotics of some integrals containing ?(t) [PDF]

, 2022
A modular relation of the form F(?,w)=F(?,iw), where i=??1and ??=1, is obtained. It involves the generalized digamma function ?w(a) which was recently studied by the authors in their work on developing the theory of the generalized Hurwitz zeta function ?

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.

A fractional residue theorem and its applications in calculating real integrals

Bulletin of the London Mathematical Society, Volume 58, Issue 4, April 2026.
Abstract As part of an ongoing effort to fractionalise complex analysis, we present a fractional version of the residue theorem, involving pseudo‐residues calculated at branch points. Since fractional derivatives are non‐local and fractional powers necessitate branch cuts, each pseudo‐residue depends on a line segment in the complex plane rather than a
