Assessment of Aircraft Coating Resistance to Lighting Strikes and Long-Term Environmental Impact

open access: yesAerospace, 2023
During an aircraft’s flight through the atmosphere, the aircraft structure interacts with the surrounding environment. One of the potential hazards that can occur is a lightning strike to the structure covering. Subsequent damage to the aircraft covering

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

open access: yesFEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

A Review of Research on Flight Delay Propagation: Current Situation and Prospect

open access: yesJournal of Advanced Transportation
The correlation between flight routes makes the initial delays easy to cause chain delays of downstream airports, forming a large area of delays. Studying delay propagation can block its propagation path and alleviate large-scale delay problems.
