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 ...

Parametric Study of an Air Charged Franchot Engine with Novel Hot and Cold Isothermalizers

open access: yesInventions, 2017
The Stirling engine is an external combustion engine that uses heat exchangers to enhance the addition and removal of energy. This makes the engine power-dense but expensive, less efficient and complicated. In this contribution, the Stirling engine based

Legacy Knowledge on Landscape Soil Carbon—Concentrated Organic Input to Selected Sites Comes With the Expense of Soil Health of Larger Areas

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Xu et al. show that high organic input and N‐balancing fertilization improve soil health at the soil plot scale; however, the effects of allocating C and N on soil health at the landscape or region scale are not considered. Historical soil management systems show that such a depletive redistribution leads to local agricultural improvements ...
