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

KONA 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

Engineering 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

Tsukuba 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 ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

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

Discrete 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 ...

Keratin 19 as a prognostic marker and contributing factor of metastasis and chemoresistance in high‐grade serous ovarian cancer

Molecular Oncology, EarlyView.
Keratin 19 (KRT19) is overexpressed in high‐grade serous ovarian cancer with high levels of Kallikrein‐related peptidases (KLK) 4–7 and is associated with poor survival. In vivo analyses demonstrate that elevated KRT19 increases peritoneal tumour burden.

CCDC80 suppresses high‐grade serous ovarian cancer migration via negative regulation of B7‐H3

Molecular Oncology, EarlyView.
PAX8 is a lineage‐specific master regulator of transcription in high‐grade serous ovarian cancer (HGSC) progression. We show for the first time that PAX8 facilitates proliferation and metastasis by repressing the cell autonomous tumor suppressor CCDC80 and inducing B7‐H3 expression.

Interpreting the effects of DNA polymerase variants at the structural level

Molecular Oncology, EarlyView.
Using MAVISp and molecular dynamics simulations, we analyzed over 60 000 missense variants in POLE and POLD1 from ClinVar, COSMIC, cBioPortal, and saturation mutagenesis. Identified mechanistic indicators, including stability, binding, and long‐range, enable structural interpretation, providing ACMG‐like evidence for possible reclassification of VUS ...

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

Archives 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.

Clinical performance of the urine‐based TERT promoter AbsoluteQ Digital PCR for non‐invasive detection of bladder cancer

Molecular Oncology, EarlyView.
A urine‐based digital PCR assay targeting two hotspot TERT promoter variants detected bladder cancer with high sensitivity and no false positives in this case–control cohort. The streamlined AbsoluteQ workflow outperformed Sanger sequencing and supports non‐invasive molecular testing for bladder cancer detection.
