The article describes the problem of invasive earthworms in hardwood forests near the Great Lakes of the U.S. The extinction of the earthworms native to the region in the most recent Ice Age is noted, mentioning that earthworms extant in the area as of 2009 have been introduced through other means.

Abstract This paper shows that optimal exchange rate policy can be defined in terms of either a long-run secular policy or a short-run stabilization policy. The rate of crawl which maximizes real per capita consumption is shown to often differ from the exchange rate movements produced under fixed or floating exchange rates.

Abstract This paper shows that the optimal exchange rate policies proposed by Mathieson will exist only for ‘perverse’ money demand function. In general these policies will minimise rather than maximise steady-state consumption.

Crawling of keratocytes derived from aquatic vertebrates represents a very useful model system for the investigation of cell locomotion because of its ease of handling and the clear structural separation of a thin cytoplasmic layer, the lamella, from the cell body containing the nucleus and other organelles.

Underactuated systems are those processing fewer actuators than degrees of freedom. Decrease of the number of actuators is a merit from the point of view of size and weight of the system. But generally it is difficult to control the underactuated system. In this paper we realize crawling motion by an underactuated robot.

The Machinery of Cell Crawling
Scientific American, 1994When a cell crawls, part of its fluid cytoplasm briefly turns rigid. This transformation depends on the orderly assembly and disassembly of a protein scaffold.

All these games can be played inside or out. If you're inside, make sure the space you use is child-friendly. It is easy to make your own soft play area using cushions and pillows, setting them out to allow you and your child the space and freedom to play physical games in safety.

Speculation and the Crawling Peg
Economica, 1977The objective of this paper is to determine how speculative capital flows, as described by the modern stock equilibrium theory, affect the stability of the path of the exchange rate under crawling peg systems. Because of the recent emphasis on objective indicators in discussions of reform of the international adjustment mechanism, the paper ...

On the Crawling of Animal Cells
Science, 1993Cells crawl in response to external stimuli by extending and remodeling peripheral elastic lamellae in the direction of locomotion. The remodeling requires vectorial assembly of actin subunits into linear polymers at the lamella's leading edge and the crosslinking of the filaments by bifunctional gelation proteins.
