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.

The Mass Dependance of Satellite Quenching in Milky Way-like Halos [PDF]

open access: yes, 2014
Using the Sloan Digital Sky Survey, we examine the quenching of satellite galaxies around isolated Milky Way-like hosts in the local Universe. We find that the efficiency of satellite quenching around isolated galaxies is low and roughly constant over ...

Using publicly available satellite imagery and deep learning to understand economic well-being in Africa

open access: yesNature Communications, 2020
Accurate and comprehensive measurements of economic well-being are fundamental inputs into both research and policy, but such measures are unavailable at a local level in many parts of the world. Here we train deep learning models to predict survey-based

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 ...

M2C-GVIO: motion manifold constraint aided GNSS-visual-inertial odometry for ground vehicles

open access: yesSatellite Navigation, 2023
Visual-Inertial Odometry (VIO) has been developed from Simultaneous Localization and Mapping (SLAM) as a low-cost and versatile sensor fusion approach and attracted increasing attention in ground vehicle positioning.

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.

Analysis of GPS P(Y) signal power enhancement based on the observations with a semi-codeless receiver

open access: yesSatellite Navigation, 2022
The Global Position System (GPS) satellites of Block IIR-M and later versions can turn on the signal power enhancement if needed. In recent years, this power enhancement has been triggered several times when the U.S force was involved in local conflicts,
