Using the Lubrication Approximation to Model the Effects of Viscosity in DEM Simulations for Complex Flow Regimes

open access: yesKONA Powder and Particle Journal
This study explores an efficient approach to modelling the flow of particles in wet granular systems using the Discrete Element Method (DEM). Typically, when particles move in a viscous fluid, DEM is coupled with Computational Fluid Dynamics (CFD) or ...

Peristaltic flow of Eyring-Powell nanofluid under the action of an electromagnetic field

open access: yesEngineering Science and Technology, an International Journal, 2019
Electro-kinetic peristaltic flow of Eyring-Powell nanofluid has been investigated in this paper. The flow is considered to take place in an asymmetric wavy micro-channel.

Magnetohydrodynamic approximation of the complete equations for an electromagnetic fluid

open access: yesTsukuba Journal of Mathematics, 1986
The authors give a singular limit theorem for the magnetohydrodynamic equations in two space dimensions, which are obtained as the limit of the complete equations for the electromagnetic fluid at the vanishing of the dielectric constant. They show convergence of the solutions of the complete equations to the solutions of the magnetohydrodynamic ...

Rab14 regulates the transport of human papillomavirus to the trans‐Golgi network for infectious cell entry

open access: yesFEBS Letters, EarlyView.
This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.

Hm Convergence of the Second-Grade Fluid Equations to Euler Equations in ℝd

open access: yesDiscrete Dynamics in Nature and Society, 2020
In this paper, we investigate an approximation of the Euler equation by the second-grade fluid equations in ℝdd=2,3. The convergence in Hm of a sequence of solutions to the second-grade fluid equations in a uniform interval is proven as both the ...

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

open access: yesFEBS 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.

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

open access: yesFEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

The self power of a clamped circular plate. An analytical estimation

open access: yesArchives of Acoustics, 2003
A low frequency approximation for the self power of a clamped crcular plate is presented in a form useful for some efficient numerical computations. The approximation is precise enough within nearly the whole low frequency range.

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

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

open access: yesFEBS 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 ...
