A Novel Inverse Statistical Model for Lifetime and Reliability Analysis

Engineering Reports, Volume 7, Issue 8, August 2025.
This paper introduces and studies the inverse Mustapha type‐II distribution (IMUIID), a new model obtained through the inverse transformation of the Mustapha type‐II distribution. The IMUIID is defined on the positive real line and offers enhanced flexibility in modeling lifetime and reliability data, particularly where traditional models may fail to ...

The robust Orlicz risk with an application to the green photovoltaic power generation

Asian Journal of Control, Volume 27, Issue 4, Page 1655-1667, July 2025.
Abstract We propose a novel recursive utility for controlling stochastic processes under risk and uncertainty. Our formulation uses a robustified Orlicz risk that can evaluate risk and uncertainty simultaneously. We focus on the control problem of a photovoltaic power generation system that supplies excess electricity for the secondary purpose of ...

Sine Power Unit Inverse Lindley Model: Bayesian Analysis and Practical Application

Engineering Reports, Volume 7, Issue 6, June 2025.
ABSTRACT Techniques for trigonometric transformation have become an effective way to modify statistical distributions. These methods provide more flexibility in modeling various real‐world phenomena by precisely adjusting skewness without adding complexity to the model.

Adaptive Maximization of Social Welfare

Econometrica, Volume 93, Issue 3, Page 1073-1104, May 2025.
We consider the problem of repeatedly choosing policies to maximize social welfare. Welfare is a weighted sum of private utility and public revenue. Earlier outcomes inform later policies. Utility is not observed, but indirectly inferred. Response functions are learned through experimentation.

Scale‐Dependent Inverse Temperature Features Associated With Crashes in the US and Japanese Stock Markets

Complexity, Volume 2025, Issue 1, 2025.
Some complex systems (e.g., an ecosystem) in direct contact with an environment can be assigned the temperature of the environment. Other complex systems, such as human beings, can maintain a core temperature of 36.5°C in environments with different temperatures, at least for a short period of time.

Structure and diversity patterns of coralligenous cliffs across three ecoregions in the Central‐Western Mediterranean Sea

Diversity and Distributions, Volume 30, Issue 9, September 2024.
Abstract Aim Coralligenous reefs are the main marine bioconstructions in terms of spatial distribution within the Mediterranean basin. Two distinct reef morphologies can be distinguished based on the surface and topographical features of the seafloor: cliffs developing vertical slopes and banks found on gently steep or horizontal bottoms. Despite their

Residual Tsallis Entropy and Record Values: Some New Insights

, 2023
Recently, the uncertainty aspects of record values have been increasingly studied in the literature. In this paper, we study the residual Tsallis entropy of upper record values coming from random samples.

The Separability Problem in Molecular Quantum Systems: Information‐Theoretic Framework for Atoms in Molecules

ChemPhysChem, Volume 25, Issue 14, July 15, 2024.
We explore the mathematical underpinnings of partitioning a molecule into its constituent atoms through the Atoms‐in‐Molecules (AIM) approach, validating its applicability through concepts from Information Theory. We present information‐theoretic justifications for employing some of the most widely utilized AIM partitioning schemes in chemistry, such ...

Some Properties of Fractal Tsallis Entropy

, 2023
We introduce fractal Tsallis entropy and show that it satisfies Shannon–Khinchin axioms. Analogously to Tsallis divergence (or Tsallis relative entropy, according to some authors), fractal Tsallis divergence is defined and some properties of it are ...
