Microwave welding of polymers [PDF]

EPJ Web of Conferences
The growing demand for fast, efficient and environmentally friendly polymer joining techniques has intensified research on microwave welding methods. However, there remains a knowledge gap regarding the influence of susceptor composition, welded material

Lattice Boltzmann simulation of wetting gradient accelerating droplets merging and shedding on a circumferential surface

Engineering Applications of Computational Fluid Mechanics, 2022
A lattice Boltzmann method (LBM) based on Shan-Chen pseudo-potential model is used to investigate the process of droplets merging and shedding on a gradient wetting circular surface.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Identification of a Shiga toxin A‐derived peptide internalized into Gb3 receptor‐bearing cells via interaction with the Shiga toxin B subunit

FEBS Letters, EarlyView.
The process of internalization of the Shiga toxin A subunit via formation of a complex with the Shiga toxin B subunit, which specifically binds to the Gb3 receptor. The peptide is designed to act as a carrier of drugs into cancer cells. Here, we explored the potential of peptides derived from the catalytic A subunit of Shiga toxin (STxA) to be drug ...

Vertical motion of particles in vibration-induced granular capillarity

EPJ Web of Conferences, 2017
When a narrow tube inserted into a static container filled with particles is subjected to vertical vibration, the particles rise in the tube, much resembling the ascending motion of a liquid column in a capillary tube.

Diffeomorphisms and Nonlinear Heat Flows [PDF]

SIAM Journal on Mathematical Analysis, 2005
We show that the gradient flow ${\mathbf u}$ on $L^2$ generated by the energy functional $I[{\mathbf u}] := \int_U \Phi(\det D{\mathbf u}) \, dx$ for vector-valued mappings is in some sense "integrable," meaning that (i) the inverse Jacobian $\beta := (\det D{\mathbf u})^{-1}$ satisfies a scalar nonlinear diffusion equation, and (ii) we can recover ...
