Capturing State‐of‐Charge‐Dependent Efficiency in Battery Energy Storage Systems: A Bernoulli Model Approach

Battery Energy, Volume 5, Issue 3, May 2026.
Conventional battery energy storage system models assume constant efficiencies, overlooking key physical limitations. This work introduces an analytical model with realistic state‐of‐charge (SOC)‐dependent efficiencies and charge acceptance, predicting that system operation concentrates in intermediate SOC ranges—a critical, overlooked behaviour ...

Representations by probabilistic Bernoulli and degenerate Bernoulli polynomials

We investigate the representation of arbitrary polynomials using probabilistic Bernoulli and degenerate Bernoulli polynomials associated with a random variable $Y$, whose moment generating function exists in a neighborhood of the origin. In addition, this paper explores the problem of representing arbitrary polynomials in terms of their higher-order ...

Sheffer type degenerate Euler and Bernoulli polynomials

Filomat, 2019
In this paper, we study some special polynomials which are related to Sheffer sequence. In addition, we give some new identities for these numbers and polynomials.

Evaluation of cauchy polynomials via degenerate r-Stirling numbers

Mathematical and Computer Modelling of Dynamical Systems
In this paper, within the framework of unsigned degenerate [Formula: see text]-Stirling numbers, we establish connections among Cauchy polynomials, degenerate Bernoulli polynomials, and degenerate hyperharmonic numbers.

Illustrating Implications of Misaligned Causal Questions and Statistics in Settings With Competing Events and Interest in Treatment Mechanisms

Statistics in Medicine, Volume 45, Issue 10-12, May 2026.
ABSTRACT In the presence of competing events, many investigators are interested in a direct treatment effect on the event of interest that does not capture treatment effects on competing events. Classical survival analysis methods that treat competing events like censoring events, at best, target a controlled direct effect: the effect of the treatment ...

Predicting Win‐Loss Probabilities for Composite Time‐to‐Event Outcomes Under The Proportional Win‐Fractions Regression Model

Statistics in Medicine, Volume 45, Issue 10-12, May 2026.
ABSTRACT For composite time‐to‐event outcomes, the win ratio as a relative measure ignores ties resulting from non‐occurrence of events, which can obscure important context in regression settings where event rates—and hence the proportion of ties—vary over time and across covariate values.

Some Identities of Fully Degenerate r-Dowling Polynomials Arising from λ-Umbral Calculus

Mathematics
This paper introduces fully Dowling polynomials of the first and second kinds, which are degenerate versions of the ordinary Dowling polynomials. Then, several important identities for these degenerate polynomials are derived.

Some identities of degenerate special polynomials

Open Mathematics, 2015
In this paper, by considering higher-order degenerate Bernoulli and Euler polynomials which were introduced by Carlitz, we investigate some properties of mixed-type of those polynomials.

Some identities involving Bernoulli, Euler and degenerate Bernoulli numbers and their applications

Applied Mathematics in Science and Engineering, 2023
The paper has two main objectives. Firstly, it explores the properties of hyperbolic cosine and hyperbolic sine functions by using Volkenborn and the fermionic p-adic integrals, respectively.

Identification and Estimation of Large Network Games with Private Link Information

International Economic Review, Volume 67, Issue 2, Page 411-432, May 2026.
ABSTRACT We study the identification and estimation of large network games in which individuals choose continuous actions while holding private information about their links and payoffs. Extending the framework of Galeotti et al., we build a tractable empirical model of such network games and show that the parameters in individual payoffs are ...
