The size of the functional base of support decreases with age
Scientific ReportsFalls occur more often as we age. To identify people at risk of falling, balance analysis requires an accurate base-of-support model. We previously developed a functional base-of-support (fBOS) model for standing young adults and showed that its area is ...

Dynamic Gait Stability Estimated Using One or Two Inertial Measurement Units Worn on the Human Body
SensorsThe margin of stability (MoS) is a metric used to assess dynamic postural stability during walking. Although MoS is typically computed from optical motion capture data, previous studies have shown that MoS can be approximated from six-axis kinematic ...

Small RNA pathways in mammalian oocytes
FEBS Open Bio, EarlyView.Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...

Variable‐speed method for improving the performance of a mine counter‐rotating fan
Energy Science & Engineering, 2020 Existing methods of improving the performance of mine counter‐rotating fans (MCRFs) through speed matching of the rotors have certain drawbacks. This study proposes a variable‐speed method for the two rotors of an MCRF to improve its performance ...

The Margin of Stability During a Single-Turn Pirouette in Female Amateur Dancers: A Pilot Study
Applied SciencesBalance control in pirouettes has previously been characterized by constraint of the topple angle. However, there is a paucity of research using the margin of stability (MoS) as a dynamic measure of balance related to pirouettes.

Research on influencing factors and improving methods for DC distribution system stability
The Journal of Engineering, 2019 In this paper, the Nyquist admittance ratio criterion was used to analyse the influencing factors on the stability of the system, such as the parameters of DC line, the intensity of interconnected AC power grid, the droop coefficient and etc.
