    Radiatively driven convection: diffusivity-free regimes of geophysical and astrophysical flows in the laboratory by Hadjerci, Gabriel, Bouillaut, Vincent, Miquel, Benjamin, Aumaître, Sébastien, Gallet, Basile

    Published 2024-12-01
    “…The widespread belief is that the transport properties of the turbulent flow should be independent of the tiny molecular diffusivities for asymptotically strong driving, but the associated “ultimate” scaling regime proves challenging to observe experimentally using standard convection cells (Rayleigh–Bénard geometry). …”

    PAX8 Distinguishes Diffuse Large B-Cell Lymphoma Mimicking Sarcoma by Michelle S. Hirsch, Alessandra F. Nascimento

    Published 2017-01-01
    “…In this case report, PAX8 was a diagnostic clue for revising a previous diagnosis of unclassified high grade sarcoma to diffuse large B-cell lymphoma. This case report demonstrates a pitfall for PAX8 immunoreactivity and acts as a reminder that lymphoma should be included in the differential diagnosis of a PAX8 positive, epithelial cell marker negative tumor of unknown primary origin.…”

    Multifeature Contrast Enhancement Algorithm for Digital Media Images Based on the Diffusion Equation by Jijun Wang, Yi Yuan, Guoxiang Li

    Published 2022-01-01
    “…In this paper, the image enhancement algorithm of nonlinear diffusion filtering is used to add a velocity term to the diffusion function using a coupled denoising model, which makes the diffusion of the original model smooth, and the interferogram is solved numerically with the help of numerical simulation to verify the denoising processing effect before and after the model correction. …”
