Shock Wave Capturing Numerically in Two Dimensional Supersonic Wind Tunnel for Different Configuration [PDF]

open access: yesEngineering and Technology Journal, 2012
Numerical solutions of two dimensional Euler equations are obtained for transonic and supersonic flows. The shock capturing method is employed to solve compressible Euler equations by using MacCormack's time marching method that an explicit finite ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

open access: yesFEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

A Review of Convective Schemes Used for Detonation Simulations in OpenFOAM After a Decade of Development

open access: yesAxioms
Detonation phenomena in reactive flow systems continue to pose significant challenges for accurate simulation, particularly in 3D validation against experiments and achieving community standardization for schemes.

Recognition of shock-wave patterns from shock-capturing solutions

open access: yes, 2012
A new technique for detecting shock waves and recognising the shock patterns in compressible flow solutions computed by means of shock-capturing solvers is proposed and discussed.

The VHL tumor suppressor at the crossroad of protein folding, aggregation, and cancer

open access: yesMolecular Oncology, EarlyView.
Mutations, environmental stress, and chaperone dysfunction can destabilize pVHL, promoting its conversion from the native folded state into amyloid‐like assemblies. This transition may contribute to protein storage, cell dormancy, survival, and drug resistance.

Optimization of seminal extracellular vesicle isolation protocols for cancer biomarker analysis using proteomic profiling

open access: yesMolecular Oncology, EarlyView.
This paper shows that size‐exclusion chromatography and sequential centrifugation applied to seminal plasma enrich for different populations of extracellular vesicles. This may significantly affect the detection and analysis of extracellular vesicle‐associated cancer biomarkers.

Hyperosmotic stress‐induced redistribution of pre‐mRNA cleavage factor I subunits is associated with shifts in alternative polyadenylation

open access: yesFEBS Open Bio, EarlyView.
Hyperosmotic stress triggers the relocation of the CFIm complex from the nucleus to the cytoplasm. This shift creates a nuclear ‘stoichiometric bottleneck’, limiting CFIm availability for mRNA processing. Consequently, specific mRNAs like NUDT21 and DICER1 undergo targeted 3′UTR shortening, demonstrating how spatial protein dynamics drive rapid ...

Hybrid Hermite TENO scheme with a simple smoothness indicator for compressible flow simulations

open access: yesResults in Applied Mathematics, 2022
The Hermite targeted essentially non-oscillatory (HTENO) scheme offers an excellent small-scale resolution and better shock-capturing capability in solving compressible flow problems.

Development of an unsteady shock-fitting technique for unstructured grids

open access: yes, 2017
A novel, unstructured, shock-fitting algorithm capable of simulating unsteady flows has recently being developed. The capabilities of this novel unstructured shock-fitting technique are here tested by reference to the inviscid interaction between a ...

Improving the quantification of overshooting shock-capturing oscillations [PDF]

open access: yes, 2023
An approach for quantitatively evaluating overshooting oscillations is designed to characterize the performance of shock-capturing schemes. Specifically, following our previous work focused on cases with only discontinuities, now we account for the ...
