A conceptual theory of state changes [PDF]
Semiotica, 1989 I will focus in this paper on what John Sowa calls the 'conceptual relations': In the formal theory there is only one primitive relation called LINK. All others are introduced by definitions. For a practical knowledge representation system, a reasonable number of basic relations should be provided for all the common relations that are used in ordinary ...

Artificial molecular machines and motors—Design and control of nanoscale motion
FEBS Letters, EarlyView.Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...
