Characterization of Effective Diffusion within Viscoelastic Fluids with Elastic Instabilities
Fluids, 2022 We considered effective diffusion, characterized by magnitudes of effective diffusion coefficients, in order to quantify mass transport due to the onset and development of elastic instabilities.

Simulations of the Poynting--Robertson Cosmic Battery in Resistive Accretion Disks
, 2007 We describe the results of numerical "2.5--dimensional" MHD simulations of an initially unmagnetized disk model orbiting a central point--mass and responding to the continual generation of poloidal magnetic field due to a secular source that emulates the

Star formation in self-gravitating disks in active galactic nuclei. I. Metallicity gradients in broad line regions [PDF]
, 2011 It has been suggested that the high metallicity generally observed in active galactic nuclei (AGNs) and quasars originates from ongoing star formation in the self-gravitating part of accretion disks around the supermassive black holes.

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Transient convective diffusion to a disk electrode [PDF]
Journal of Electroanalytical Chemistry, 1974 Summary Mass transfer to a rotating disk electrode is calculated at large times after aconcentration step or a flux step at the surface. Radial dependence of concentration is ignored. Further application of results to treat more complex boundary conditions is discussed.

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 ...

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.

Antimicrobial susceptibility testing of Dermabacter hominis
Microbiology SpectrumDermabacter hominis, a short gram-positive rod, is a part of the human skin flora, but can also cause infections (e.g., skin and soft tissue infections, bone and joint infections, abscesses, peritoneal dialysis-associated peritonitis, and bacteremia ...

Mean exit time for surface-mediated diffusion: spectral analysis and asymptotic behavior
, 2014 We consider a model of surface-mediated diffusion with alternating phases of pure bulk and surface diffusion. For this process, we compute the mean exit time from a disk through a hole on the circle.
