Focus on dynamics of particles in turbulence

New Journal of Physics, 2014
Studies on the dynamics of particles in turbulence have recently experienced advances in experimental techniques, numerical simulations and theoretical understandings. This ‘focus on’ collection aims to provide a snapshot of this fast-evolving field.

Effects of polymer additives in the bulk of turbulent thermal convection

, 2015
We present experimental evidence that a minute amount of polymer additives can significantly enhance heat transport in the bulk region of turbulent thermal convection. The effects of polymer additives are found to be the \textit{suppression} of turbulent

Dimethyl fumarate combined with cisplatin at subcytotoxic doses sensitizes cervical cancer toward ferroptosis and apoptosis through GSH restriction and p53 (re)activation

Molecular Oncology, EarlyView.
Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.

Possible seed for internal transport barriers in L-mode plasmas modeled on JT-60U reversed magnetic-shear discharge subject to profile constraints

Nuclear Fusion
We study low confinement mode (L-mode) plasmas modeled on JT-60U reversed magnetic-shear discharges using $\delta f$ -based global gyrokinetic simulations, which exhibit strong profile constraints arising from two spatially separated instability free ...

A κ−ε model for plasma anomalous transport in tokamaks: closure via the scaling of the global confinement

Nuclear Materials and Energy, 2019
A reduced model for radial anomalous transport of plasma in tokamaks, inspired by the Reynolds-Averaged Navier–Stokes (RANS) approach, is presented assuming diffusion as governing mechanism. In order to self-consistently calculate transport coefficients,

A multiple-scale model for compressible turbulent flows [PDF]

A multiple-scale model for compressible turbulent flows is proposed. It is assumed that turbulent eddy shocklets are formed primarily by the 'collisions' of large energetic eddies.

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

Molecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

ITG turbulence in gyrokinetic simulations of high collisionality spherical tokamak plasmas

Nuclear Fusion
This paper presents a first detailed gyrokinetic analysis with the goal of understanding the dominant turbulent transport mechanisms and identifying the micro-instabilities present in small-aspect-ratio plasmas in the PI3 device, developed as magnetized ...

Lateral transport of traffic pollutants in complex urban area

EPJ Web of Conferences, 2018
Owing to the spatial variability of an urban area, even the transport of passive scalar is complex. The examination of the pollutant transport in such turbulent flow as occur within the urban canopy requires the measurements not only the advective but ...
