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 ...

GLEAM v3: satellite-based land evaporation and root-zone soil moisture

open access: yes, 2016
. The Global Land Evaporation Amsterdam Model (GLEAM) is a set of algorithms dedicated to the estimation of terrestrial evaporation and root-zone soil moisture from satellite data. Ever since its development in 2011, the model has been regularly revised,

Assessment of tomographic window and sampling rate effects on GNSS water vapor tomography

open access: yesSatellite Navigation, 2023
The ground-based Global Navigation Satellite System (GNSS) water vapor tomography is increasingly important in GNSS meteorology. As the multi-GNSS and more ground-based GNSS sites can be incorporated into the regional water vapor tomographic model ...

Semi-analytical assessment of the relative accuracy of the GNSS/INS in railway track irregularity measurements

open access: yesSatellite Navigation, 2021
An aided Inertial Navigation System (INS) is increasingly exploited in precise engineering surveying, such as railway track irregularity measurement, where a high relative measurement accuracy rather than absolute accuracy is emphasized.

Satellite Communications

open access: yesEURASIP Journal on Wireless Communications and Networking, 2008
The call for papers resulted in a high number of submis- sions, from which we have been able to select 12 excellent papers dealing with the different aspects of satellite commu- nications and navigation. Multiple-input multiple-output (MIMO) techniques are attracting a considerable amount of attention from within the terrestrial wireless community. The

Culture conditions influence satellite cell activation and survival of single myofibers [PDF]

open access: yes, 2018
Single myofiber isolation protocols allow to obtain an in vitro system in which the physical association between the myofiber and its stem cells, the satellite cells, is adequately preserved.
