Vortex-Induced Vibration Characteristics of a PTC Cylinder with a Free Surface Effect
Energies, 2020 The experimental study of vortex induced vibration needs to be carried out in water tunnel, but in previous associated simulation work, the water tunnel was treated as an infinite flow field in the depth direction with the effect of the free surface ...

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

The effects of barriers on supershear rupture
Geophysical Research Letters, 2016 A barrier may induce a supershear rupture transition in some cases, whereas it may prevent the further propagation of a supershear rupture in other cases.

Capillary Effects on Surface Enhancement in a Non-Homogeneous Fibrous Porous Medium [PDF]
Mechanics of Advanced Composite Structures, 2018 The evaluation of a free fluid surface in a porous medium has several mathematical applications that are important in industries using molds, particularly in the fluid injection process.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Computational Fluid Dynamics Analysis of Cavitating Hydrofoils Near the Sea Surface in Supercritical Open Channel Flows [PDF]
Journal of Applied Fluid MechanicsAs a high-speed submerged body travels beneath the water surface, it induces deformation of the free surface and may generate cavitation due to local pressure reductions.

, 2022 This thesis investigates several free-surface phenomena to illustrate the role of viscous stresses. In part I (chapters 1-4), we study the impact of spherical liquid drops on non-wetting substrates. After impact on a rigid substrate, a falling liquid drop deforms and spreads, owing to the normal reaction force.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane
FEBS Letters, EarlyView.Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...
