Hovering hawkmoths exploit unsteady circulation to produce aerodynamic force.

This study employs an integrated approach, combining three-dimensional flow visualization and two-dimensional flow measurement to investigate the underlying unsteady aerodynamic mechanisms of hovering hawkmoths. Using a single vortex ring model, three aerodynamic force components, such as aerodynamic force induced by unsteady circulation, vortex loop size variation and added mass, are estimated within a dimensionless time (normalized by one wing beat cycle) range of 0.418 < < 0.

Hummingbirds use compensatory eye movements to stabilize both rotational and translational visual motion.

To maintain stable vision, behaving animals make compensatory eye movements in response to image slip, a reflex known as the optokinetic response (OKR). Although OKR has been studied in several avian species, eye movements during flight are expected to be minimal. This is because vertebrates with laterally placed eyes typically show weak OKR to nasal-to-temporal motion (NT), which simulates typical forward locomotion, compared with temporal-to-nasal motion (TN), which simulates atypical backward locomotion.

Firm ownerships matter in measuring carbon footprints and its driving forces in China's domestic value chains.

Some research has studied the carbon footprints of the multinational enterprises (MNEs) in the global value chains (GVCs). However, currently there are few studies have studied the carbon footprints of the foreign invested firms (FIFs) distributed in different provinces in China's domestic value chains (DVCs). This paper has used China's inter-provincial input-output table distinguishing domestically owned enterprises (DEs), Hong Kong, Macao, and Taiwan (HMTs) invested enterprises and other foreign invested enterprises (FIEs) to study the carbon footprints of the FIFs in China's DVCs and further analyzed the driving factors of the carbon footprints change.

Rational Electrolyte Design for Elevated-Temperature and Thermally Stable Lithium-Ion Batteries with Nickel-Rich Cathodes.

As the energy density of lithium-ion batteries (LIBs) increases, the shortened cycle life and the increased safety hazards of LIBs are drawing increasing concerns. To address such challenges, a series of localized high-concentration electrolytes (LHCEs) based on a solvating-solvent mixture of tetramethylene sulfone and trimethyl phosphate and a high flash-point diluent 1H,1H,5H-octafluoropentyl 1,1,2,2-tetrafluoroethyl ether were designed. The LHCEs exhibited nonflammability and greatly suppressed heat release at elevated temperatures, which would potentially improve the safety performance of the LIBs.
