Focused Crawl of Web Archives to Build Event Collections [PDF]

arXiv, 2018
Event collections are frequently built by crawling the live web on the basis of seed URIs nominated by human experts. Focused web crawling is a technique where the crawler is guided by reference content pertaining to the event. Given the dynamic nature of the web and the pace with which topics evolve, the timing of the crawl is a concern for both ...

Tuning gastropod locomotion: Modeling the influence of mucus rheology on the cost of crawling [PDF]

Phys. Fluids (2006) 18, 113102, 2006
Common gastropods such as snails crawl on a solid substrate by propagating muscular waves of shear stress on a viscoelastic mucus. Producing the mucus accounts for the largest component in the gastropod's energy budget, more than twenty times the amount of mechanical work used in crawling.

On the Swimming of \textit{Dictyostelium} amoebae [PDF]

, 2010
Traditionally, the primary mode for locomotion of amoeboid cells was thought to be crawling on a substrate. Recently, it has been experimentally shown that \textit{Dictostelium} amoeba and neutrophils can also swim in a directed fashion. The mechanisms for amoeboid crawling and swimming were hypothesized to be similar.

An Earthworm-Inspired Soft Crawling Robot Controlled by Friction [PDF]

arXiv, 2017
We present the modeling, design, fabrication and feedback control of an earthworm-inspired soft robot capable of crawling on surfaces by actively manipulating the frictional force between its body and the surface. Earthworms are segmented worms composed of repeating units known as metameres.

Qualitative assessment in the third month of life allows for a better prognosis of the achievement of motor milestones versus assessment of pathological reflexes- prospective studies on Polish children

Frontiers in Public Health, 2023
IntroductionThe characteristic feature of primitive reflexes is that they occur early in development and must expire at a well-defined age. The study was conducted prospectively on a group of 107 children (74 boys).

The Relationship between Crawling and Emotion Discrimination in 9- to 10-Month-Old Infants

Brain Sciences, 2022
The present study examined whether infants’ crawling experience is related to their sensitivity to fearful emotional expressions. Twenty-nine 9- to 10-month-old infants were tested in a preferential looking task, in which they were presented with ...

Early Motor Milestones in Infancy and Later Motor Impairments: A Population-Based Data Linkage Study

Frontiers in Psychiatry, 2022
BackgroundDevelopmental Coordination Disorder (DCD) is a neurodevelopmental condition with high prevalence. Early motor milestones are important markers to identify DCD. The current study aims to evaluate the association between the onset of crawling and
