FLAMINGo video: Extrusion Process by Constellium
<p>The extrusion process at Constellium's University Technology Center involves manufacturing Al-MMC specimens and parts. Widely recognized by car manufacturers for its cost-effectiveness, extrusion is a preferred method for crafting the Body in White (BIW) of a car. Following extrusion, the video showcases the investigation of quenching, a rapid cooling process that sets desired properties in aluminum components, ensuring the necessary mechanical and structural characteristics. This combination of extrusion and quenching is essential for shaping aluminum into required forms.</p>

Cervical disc extrusion with dorsal migration in a pet rabbit: Histological slides
<p>Representative IVD fragments on histological slides after Giemsa (A: Gie) and haematoxylin eosin stain (B: HE). Fragments consist of hyaline (empty arrows) and fibrocartilage (black arrows) and present with atypical polycellular chondrocyte clusters (PLC) as well as with large mineralized areas, better seen on HE (asterisks). Scale bar for both: 510 µm.</p>
Movie files: Actin dynamics and the Bmp pathway drive apical extrusion of proepicardial cells.
<p>The epicardium, the outer mesothelial layer enclosing the myocardium, plays key roles in heart development and regeneration. During embryogenesis it arises from the proepicardium (PE), a cell cluster that appears in the dorsal pericardium (DP) close to the venous pole of the heart. Little is known about how the PE emerges from the pericardial mesothelium. Using the zebrafish model and a combination of genetic tools, pharmacological agents and quantitative <em>in vivo</em> imaging, we reveal that a coordinated collective movement of DP cells drives PE formation. We found that BMP signaling and the actomyosin cytoskeleton promote constriction of the DP, which enabled PE cells to extrude apically. We provide evidence that cell extrusion, which has been described in the elimination of unfit cells from epithelia and the emergence of hematopoietic stem cells, is also a mechanism for PE cells to exit an organized mesothelium and fulfil the developmental fate to form a new tissue layer, the epicardium.</p>
Myers et al. - Two material analogue experiments of lava dome extrusion
<p>Here we provide the full dataset to accompany the experiments presented in Myers et al. (2024) Lava dome morphology controlled by viscosity and cohesion: analogue experiments of episodic dome growth. We systematically explored the effect of cohesion and viscosity by carrying out experiments using (1) only granular material (sand, sand with 10 wt.% gypsum, and sand with 20 wt.% gypsum); (2) each granular material with a low viscosity syrup-sugar suspension, with 30 wt.% sugar; and (3) each granular material with a high viscosity syrup-sugar suspension, with 50 wt.% sugar.</p> <p>Solid only (paper Section 3.1)<br>1.

An atomistically informed multiscale approach to the intrusion and extrusion in hydrophobic nanopores
<p>Data from Molecular Dynamics simulations.</p> <p>Files ending in .dat are the "measurement" files and are the files required to compute the free energy and diffusivity from the simulation data. The normal sintax is eqX.dat where X is the imposed filling of the pore. The names of the folders represent the pressure at which the filling was taken (0 MPa, -20 MPa, 60 MPa)</p> <p>We also attach one trajectory file, 0.xyz and one LAMMPS output file, 0.log, which should be enough to reproduce the simulation script, in conjuction with 0.data, the initial condition.</p>
