Walking Out of the Weisfeiler Leman Hierarchy: Graph Learning Beyond Message Passing [PDF]
We propose CRaWl, a novel neural network architecture for graph learning. Like graph neural networks, CRaWl layers update node features on a graph and thus can freely be combined or interleaved with GNN layers. Yet CRaWl operates fundamentally different from message passing graph neural networks.

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

How do infants decide what to do at the brink of a precipice? Infants could use two sources of information to guide their actions: perceptual information generated by their own exploratory activity and social information offered by their caregivers.

THREAT/crawl: a Trainable, Highly-Reusable, and Extensible Automated Method and Tool to Crawl Criminal Underground Forums [PDF]
Collecting data on underground criminal communities is highly valuable both for security research and security operations. Unfortunately these communities live within a constellation of diverse online forums that are difficult to infiltrate, may adopt crawling monitoring countermeasures, and require the development of ad-hoc scrapers for each different

A Novel Crawling In-pipe Robot Design
A novel crawling in-pipe robot was designed to improve the adaptive ability with self-locking principle applied. In the moving, the robot was adaptable to horizontal, vertical and bending pipes with different diameters and sections without exerting ...

Energy Considerations in a Model of Nematode Sperm Crawling
In this paper we propose a mathematical model for nematode spermcell crawling. The model takes into account both force and energybalance in the process of lamellipodium protrusion and cellnucleus drag. It is shown that by specifying the (possiblyvariable)
