The large amount of available information on the Web makes it hard for users to locate resources about particular topics of interest. Traditional search tools, e.g., search engines, do not always successfully cope with this problem, that is, helping users to seek the right information.

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.

This is a survey of the science and practice of web crawling. While at first glance web crawling may appear to be merely an application of breadth-first-search, the truth is that there are many challenges ranging from systems concerns such as managing very large data structures to theoretical questions such as how often to revisit evolving content ...

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.
