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.

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.

Optimal Beamforming for Hybrid Satellite Terrestrial Networks with Nonlinear PA and Imperfect CSIT [PDF]

open access: yes, 2020
In hybrid satellite-terrestrial networks (HSTNs), spectrum sharing is crucial to alleviate the "spectrum scarcity" problem. Therein, the transmit beams should be carefully designed to mitigate the inter-satellite-terrestrial interference.

On the Orbits of Infalling Satellite Halos [PDF]

open access: yes, 2010
The orbital properties of infalling satellite halos set the initial conditions which control the subsequent evolution of subhalos and the galaxies that they host, with implications for mass stripping, star formation quenching, and merging.
