This paper presents the results of a survey on the change in the lift coefficient of the wing profile when using flaps on the Ansys Fluent application platform. The use of these flaps is extremely important. They not only ensure safe and efficient takeoff and landing but also enable rapid takeoff to approach and destroy targets even under runway damage.

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry
FEBS Letters, EarlyView.EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Translophagy—A potential link between autophagy impairment and translational errors
FEBS Letters, EarlyView.Neurodegenerative diseases are characterised by the accumulation of abnormal proteins and protein aggregates, but their origin often remains unknown. We propose that selective autophagy removes damaged protein‐making machinery, preventing errors during protein synthesis.

Numerical Simulation of Aerodynamic Characteristics of a Leading-Edge Circulation-Control Airfoil
气体物理Traditional circulation control method can enhance the lift and increase the lift-to-drag ratio of airfoils effectively. However, its failure at high angles of attack and the additional drag caused by airfoil geometry modification in circulation-control ...

FEBS Letters, EarlyView.How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Aerodynamics of Golf Balls in Still Air
Proceedings, 2018 The following considers lift and drag measurements of 13 production golf ball models propelled through still air in a laboratory setting. The balls travelled at speeds ranging from 18 m/s to 91 m/s and spin ranging from 1500 rpm to 4500 rpm.
