Learning to Crawl [PDF]

open access: bronzeChild Development, 1998
The effects of infants' age, body dimensions, and experience on the development of crawling was examined by observing 28 infants longitudinally, from children's first attempts at crawling until they began walking. Although most infants displayed multiple crawling postures en route to walking, development did not adhere to a strict progression of ...

Crawling in a Fluid [PDF]

open access: yesPhysical Review Letters, 2019
There is increasing evidence that mammalian cells not only crawl on substrates but can also swim in fluids. To elucidate the mechanisms of the onset of motility of cells in suspension, a model which couples actin and myosin kinetics to fluid flow is proposed and solved for a spherical shape.

Crawling technicolor [PDF]

open access: yesPhysical Review D, 2019
We analyze the Callan-Symanzik equations when scale invariance at a nontrivial infrared (IR) fixed point $ ^{}_{\mathrm{IR}}$ is realized in the Nambu-Goldstone (NG) mode. As a result, Green's functions at $ ^{}_{\mathrm{IR}}$ do not scale in the same way as for the conventional Wigner-Weyl (WW) mode.

Research on Motion Mode Switching Method Based on CPG Network Reconstruction

open access: yesIEEE Access, 2020
Traditional underwater robots have many shortcomings in terms of resistance to sea currents, stability and functionality. In order to improve the efficiency and quality of underwater operations, this paper proposes and designs a new underwater robot, the

Intravascular Crawling of Patrolling Monocytes: A Lèvy-Like Motility for Unique Search Functions?

open access: yesFrontiers in Immunology, 2021
Patrolling monocytes (PMo) are the organism’s preeminent intravascular guardians by their continuous search of damaged endothelial cells and harmful microparticles for their removal and to restore homeostasis.

Transition From Crawling to Walking Changes Gaze Communication Space in Everyday Infant-Parent Interaction

open access: yesFrontiers in Psychology, 2020
Acquisition of walking changes not only infants' locomotion itself but also infants' exploratory behavior and social interaction, such as gaze communication.

Structural Design and Crawling Pattern Generator of a Planar Quadruped Robot for High-Payload Locomotion

open access: yesSensors, 2020
Load capacity is an important index to reflect the practicability of legged robots. Existing research into quadruped robots has not analyzed their load performance in terms of their structural design and control method from a systematic point of view ...
