SMI Compatible Simulation Scheduler Design for Reuse of Model Complying with SMP Standard [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2010
Software reusability is one of key factors which impacts cost and schedule on a software development project. It is very crucial also in satellite simulator development since there are many commercial simulator models related to satellite and dynamics.

HDAC4 regulates satellite cell proliferation and differentiation by targeting P21 and Sharp1 genes [PDF]

open access: yes, 2018
Skeletal muscle exhibits a high regenerative capacity, mainly due to the ability of satellite cells to replicate and differentiate in response to appropriate stimuli. Epigenetic control is effective at different stages of this process.

Post-transcriptional regulation of satellite cell quiescence by TTP-mediated mRNA decay. [PDF]

open access: yes, 2015
Skeletal muscle satellite cells in their niche are quiescent and upon muscle injury, exit quiescence, proliferate to repair muscle tissue, and self-renew to replenish the satellite cell population.

Adult skeletal muscle stem cell migration is mediated by a blebbing/amoeboid mechanism [PDF]

open access: yes, 2011
Adult skeletal muscle possesses a resident stem cell population called satellite cells which are responsible for tissue repair following damage. Satellite cell migration is crucial in promoting rapid tissue regeneration but is a poorly understood ...

The rotationally stabilized VPOS and predicted proper motions of the Milky Way satellite galaxies [PDF]

open access: yes, 2013
The satellite galaxies of the Milky Way (MW) define a vast polar structure (VPOS), a thin plane perpendicular to the MW disc. Proper motion (PM) measurements are now available for all of the 11 brightest, `classical' satellites and allow an updated ...
