Animals modulate the power output needed for different locomotor tasks by changing muscle forces and fascicle strain rates. To generate the necessary forces, appropriate motor units must be recruited. Faster motor units have faster activation-deactivation rates than slower motor units, and they contract at higher strain rates; therefore, recruitment of faster motor units may be advantageous for...

Modern agriculture is at the heart of economic and societal functioning for feeding a galloping world population, but also ensuring profit producers, processors, traders [...]

Abstract The galloping of iced conductors is a common disaster overhead conductors. Most traditional anti-galloping devices lack nonlinear dynamic vibration absorber; hence, they have limited effect. In this study, we designed, optimized, and tested an electric power fitting device with cubic stiffness particle damping for ultra-high-voltage (UHV) transmission lines. We built model the coupling...

This paper focuses on modeling the gait characteristics of a quadrupedal gallop. There have been a number of studies of the mechanics of the stance phase in which a foot is in contact with the ground. We seek to put these studies in the context of the stride, or overall motion cycle. The model used is theoretical, and is kept simple in the interest of transparency. It is compared to empirical d...

An estimated three million insect species all walk using variations of the alternating tripod gait [1]. At any one time, these animals hold one stable triangle of legs steady while swinging the opposite triangle forward. Here, we report the discovery that three different flightless desert dung beetles use an additional gallop-like gait, which has never been described in any insect before. Like ...
