    A Review on Current Osteoporosis Research: With Special Focus on Disuse Bone Loss by Roy Yuen-chi Lau, Xia Guo

    Published 2011-01-01
    “…The disuse osteoporosis refers to bone mass decrements under conditions of decreased mechanical loading, including decreased ground force reaction, muscular contraction, and microgravity-related bone loss in astronauts after space flights. Although there are many effective treatments available for primary osteoporosis, there is a lack of effective treatments for disuse osteoporosis. …”

    Allocation Optimization Strategy for High-Precision Control of Picosatellites and Nanosatellites by Bo Yang, Jun Miao, Zichen Fan, Jun Long, Xuhui Liu

    Published 2018-01-01
    “…The high-precision control of picosatellites and nanosatellites has always plagued the astronautics field. Aiming to change the status quo of the actuators not being able to meet the high-precision attitude control of picosatellites and nanosatellites, this article formulates a control allocation strategy for picosatellites and nanosatellites using the solid propellant microthruster array (SPMA). …”
