Nonlinear transverse cascade and two-dimensional magnetohydrodynamic subcritical turbulence in plane shear flows [PDF]

, 2014
We find and investigate via numerical simulations self-sustained two-dimensional turbulence in a magnetohydrodynamic flow with a maximally simple configuration: plane, noninflectional (with a constant shear of velocity) and threaded by a parallel uniform

Promiscuous stimulation of HSP70 ATPase activity by parasite‐derived J‐domains

FEBS Open Bio, EarlyView.
The malaria parasite Plasmodium falciparum exports three highly homologous yet functionally divergent J‐domain proteins into human erythrocytes. Here, we show that J‐domains isolated from all three proteins effectively stimulate the ATPase activity of both endogenous host and exported parasite HSP70 chaperones.

Boundary layer flow and heat-mass transfer of shear-thinning nanofluid past a thin needle: Electroperiodic magnetic field and thermo-diffusion effects

Nuclear Engineering and Technology
Heat and mass transfer in a boundary layer flow (BLF) of shear-thinning nanofluid (NF) around a thin needle has various practical applications including industrial processes, like medical devices, complicated cooling systems, high-efficiency thermal ...

Numerical Investigation and Thermal Performance Analysis of Smooth Absorber Tube in a Parabolic Trough Solar Collector [PDF]

E3S Web of Conferences
The thermal efficiency of parabolic trough solar collectors (PTSCs) is highly dependent on the design and material characteristics of the absorber tubes that control the performance of heat transfer and fluid flow.

Exon 7 splicing of ERα predicts poor prognosis and increases phenotypic heterogeneity in luminal a subtype breast cancer

FEBS Open Bio, EarlyView.
ERα splice variant ERα∆7 lacks the C‐terminus, and its expression may change phenotypes of breast cancers. Our results showed that ERα∆7 is found in the luminal A subtype, and elevated ERα∆7 levels are linked to improved cell survival with lower proliferation and migration.

A queuing-theoretic framework for magnetohydrodynamic flow and reactive mass transfer in Casson fluid systems with interruptions and recovery phases [PDF]

AIP Advances
This study presents a novel queuing-theoretic framework to analyze magnetohydrodynamic flow and reactive mass transfer in Casson fluid systems, particularly under conditions involving delays, interruptions, and recovery phases.

Kelvin-Helmholtz instability of a coronal streamer

, 2013
The shear-flow-driven instability can play an important role in energy transfer processes in coronal plasma. We present for the first time the observation of a kink-like oscillation of a streamer probably caused by the streaming kinkmode Kelvin-Helmholtz

Matrix metalloproteinase‐9 regulates cell adhesion and membrane protrusive activity of ovarian cancer cells

FEBS Open Bio, EarlyView.
Matrix metalloproteinase‐9 (MMP9) drives ovarian cancer progression. Using MMP9‐null cells (M9‐KO) created from ovarian cancer cells, we found MMP9 loss did not block Epidermal Growth Factor (EGF)‐driven E‐cadherin dissolution or EMT but delayed and reduced EGF‐driven membrane protrusions. Transient MMP9 re‐expression drove membrane protrusion.
