Some Bianchi Type Viscous Holographic Dark Energy Cosmological Models in the Brans–Dicke Theory.

Publication Type: Academic Journal

Source(s): Advances in Astronomy. 11/2/2022, p1-29. 29p.

Abstract: In this article, we analyze Bianchi type–II, VIII, and IX spatially homogeneous and anisotropic space-times in the background of the Brans–Dicke theory of gravity within the framework of viscous holographic dark energy. To solve the field equations, we...

Capture theory models: An overview of their development, experimental verification, and applications to ion–molecule reactions.

Publication Type: Academic Journal

Source(s): Journal of Chemical Physics. 8/14/2022, Vol. 157 Issue 6, p1-15. 15p.

Abstract: Since Arrhenius first proposed an equation to account for the behavior of thermally activated reactions in 1889, significant progress has been made in our understanding of chemical reactivity. A number of capture theory models have been developed over ...

Analyzing the Effectiveness of Finance in Supply Chain in Solving the Financing Difficulties of SMEs Based on Grey Theory Model.

Publication Type: Academic Journal

Source(s): Computational Intelligence & Neuroscience. 7/14/2022, p1-10. 10p.

Abstract: Small and medium-sized enterprises (SMEs) play an indispensable role in China's national economic system, and they can play a critical role in promoting economic growth and full employment. The main reason for the disruption and impediment to the devel...

Metaphorical Description and Model Description of Complex Systems.

Publication Type: Academic Journal

Source(s): Computational Intelligence & Neuroscience. 7/7/2022, p1-8. 8p.

Abstract: From metaphorical description to model description is the symbol of the maturity of complexity science. This paper focuses on two model description methods of complex systems: formal system model and relevance theory model, and compares their advantage...

Treating random sequential addition via the replica method.

Publication Type: Academic Journal

Source(s): Journal of Chemical Physics. 8/28/2022, Vol. 157 Issue 8, p1-13. 13p.

Abstract: While many physical processes are non-equilibrium in nature, the theory and modeling of such phenomena lag behind theoretical treatments of equilibrium systems. The diversity of powerful theoretical tools available to describe equilibrium systems has i...

A machine-learning approach for research model creation in theory building research.

Publication Type: Academic Journal

Source(s): Issues in Information Systems. 2022, Vol. 23 Issue 3, p100-113. 14p.

Abstract: We propose and illustrate an automated process for research model creation and hypothesis generation. To do so we argue that the early phases of theory building research are algorithmic and can be automated, given that a corpus of knowledge from past r...

5. IMPLICIT THEORIES OF INTELLIGENCE AND SCHOOL PERFORMANCE. A SYSTEMATIC REVIEW.

Publication Type: Academic Journal

Source(s): Review of Artistic Education. 2022, Vol. 24 Issue 1, p272-285. 14p.

Abstract: The aim of this paper was to shed a light upon the relationships between implicit theories of intelligence and school performance through a systematic review approach, which mainly used empirical studies on the connections between these constructs. In ...

On the Fractional Variable Order Thermostat Model: Existence Theory on Cones via Piece-Wise Constant Functions.

Publication Type: Academic Journal

Source(s): Journal of Function Spaces. 3/24/2022, p1-11. 11p.

Abstract: In the current manuscript, we intend to investigate the existence, uniqueness, and the stability of positive solution in relation to a fractional version of variable order thermostat model equipped with nonlocal boundary values in the Caputo sense. In ...

Flexible Item Response Models for Count Data: The Count Thresholds Model.

Publication Type: Academic Journal

Source(s): Applied Psychological Measurement. Nov2022, Vol. 46 Issue 8, p643-661. 19p.

Authors:

Abstract: A new item response theory model for count data is introduced. In contrast to models in common use, it does not assume a fixed distribution for the responses as, for example, the Poisson count model and extensions do. The distribution of responses is d...

An Empirical Identification Issue of the Bifactor Item Response Theory Model.

Publication Type: Academic Journal

Source(s): Applied Psychological Measurement. Nov2022, Vol. 46 Issue 8, p675-689. 15p.

Abstract: Using the bifactor item response theory model to analyze data arising from educational and psychological studies has gained popularity over the years. Unfortunately, using this model in practice comes with challenges. One such challenge is an empirical...
