Aerodynamics of Flight Formations in Birds: A Quest for Energy Efficiency by Fabien Beaumont, Sébastien Murer, Fabien Bogard, Guillaume Polidori

“…The results reveal a complex, undulating vortex structure shaped by the wingbeat amplitude and frequency. The analysis shows that trailing birds positioning their wingtips within the upwash region of vortices that are generated by a leading bird significantly reduce drag and enhance lift, achieving up to a 32% improvement in aerodynamic efficiency, calculated as the lift-to-drag ratio. …”

Examining household energy efficiency in China: Socioeconomic influences and policy recommendations by Xue song, Nawal Abdalla Adam, Zarmina Manzoor, Sanjar Mirzaliev, Mirzat Ullah, Dadajon Xabibullayev, Yongie Diang

“…Our key results include: (1) household energy efficiency exhibited a fluctuating trend, peaking at 0.923 in 2010, then declining to 0.861 by 2024, indicating structural inefficiencies; (2) unlike previous assumptions, the relationship between household income and energy efficiency is non-linear, where middle-income households demonstrate the sharpest efficiency decline, whereas low- and high-income groups show varying stabilization patterns post-2015; (3) regional disparities have intensified, with rural provinces exhibiting improvements in energy efficiency due to policy interventions, while urban regions struggle with overconsumption and inefficient appliance usage; (4) policy shifts post-2015, such as subsidies for energy-efficient appliances and urbanization trends, have played a crucial role in shaping efficiency dynamics. …”
