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.

Learning to Crawl

open access: yesProceedings of the AAAI Conference on Artificial Intelligence, 2020
Web crawling is the problem of keeping a cache of webpages fresh, i.e., having the most recent copy available when a page is requested. This problem is usually coupled with the natural restriction that the bandwidth available to the web crawler is limited. The corresponding optimization problem was solved optimally by Azar et al.

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

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.

Musculoskeletal Load Analysis for the Design and Control of a Wearable Robot Bracing the Human Body While Crawling on a Floor

open access: yesIEEE Access, 2022
Wearable robots, such as exoskeletons, can potentially reduce the load at targeted muscles of the human body during fatiguing tasks. It is common, however, that use of a wearable robot causes increased load at untargeted muscles, leading to minimal net ...
