... XRD peaks using the Scherrer formula [25]. This value is consistent with nanofiber size obtained by TEM analysis as shown in Figure 3. In comparison, the size of nanofibers prepared using the conventional methods ... con- taining magn etic dipoles that are arranged into a linear chain will exhibit an increase i n coercivity [33]. Our results seemed to be consistent with this predictio...

Instantaneous joint power output was calculated using the following equation: P = M × ω Where: P = power (W) M = joint moment of ... likely due to an increase in muscle forces resulting from a decrease in ergometer cadence [35]. The significant increase observed in HPO is consistent with Ericson's findings in...

... muscles crossing the joint could govern its impedance. The MCP joint has more muscles crossing it than the PIP joint, providing higher impedance and thus less motion at the MCP joint. The joint impedance ... the IP joints [22]. Kamper et al. speculated that intrinsic mus- cles may assist MCP flexion indirectly by increasing the resistance to the IP flexion [3]. Thus, flexing MCP joint...
