Poly-falling factorial sequences and poly-rising factorial sequences

open access: yesOpen Mathematics, 2021
In this paper, we introduce generalizations of rising factorials and falling factorials, respectively, and study their relations with the well-known Stirling numbers, Lah numbers, and so on.

λ-Analogues of Stirling polynomials of the first kind and their applications

open access: yesJournal of Inequalities and Applications, 2019
Recently, λ-analogues of Stirling numbers of the first kind were studied. In this paper, we introduce, as natural extensions of these numbers, λ-Stirling polynomials of the first kind and r-truncated λ-Stirling polynomials of the first kind.

The Peak of Noncentral Stirling Numbers of the First Kind

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2015
We locate the peak of the distribution of noncentral Stirling numbers of the first kind by determining the value of the index corresponding to the maximum value of the distribution.

Comparative Neuromechanical Wing‐Actuation Architectures of Flapping Flight in Insects, Hummingbirds, and Robots

open access: yesAdvanced Intelligent Systems, EarlyView.
Natural fliers achieve remarkable aerial performance through diverse wing neuromechanical systems integrating actuation, sensing, and control. This study synthesizes neuromechanical architectures in insects and hummingbirds, identifying two key functional types‐Dual Neural‐Mechanical Oscillator and Neurally‐modulated Mechanical Oscillator‐ and ...

Confessions of a Poverty Researcher: My Journey Through the Foothills of Scholarship

open access: yesAustralian Journal of Social Issues, EarlyView.
ABSTRACT This paper describes the key events, experiences and ideas that influenced the author's career as a poverty researcher. He describes how his early disillusion with economics was replaced by a spark of interest in social issues and how his migration from the UK to Australia in the mid‐1970s provided the impetus to begin what became a lifetime ...

Study on Natural Gas Decarbonization Process Based on CO2 Desublimation Characteristics

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Natural gas decarbonization is a crucial processing step. In this study, the snow separation technology for removal of carbon dioxide in natural gas based on CO2 desublimation characteristics was introduced. The phase equilibrium calculation of CH4‐CO2 and N2‐CO2 system was carried out by using cubic equations of states (EOSs), and identified ...
