Nelson belonged to those philosophers whose way of thinking resulted from a familiarity with the spirit of the exact sciences. For him, mathematics and theoretical physics formed the methodical ideal that he strived to achieve in elaborating his philosop...

Has the macroeconomic policy "regime" changed in the United States in the last few years? If so, has t h s change had an effect on macroeconomic relationships, and, in particular, on the relationshp between inflation and unemployment? These two questions have been on the minds of most macroeconomists since the October 1979 switch from interest rates to reserves as an intermediate target for the...

Strange nonchaotic attractors (SNAs) are observed in quasiperiodically driven time–delay systems. Since the largest Lyapunov exponent is nonpositive, trajectories in two such identical but distinct systems show the property of phase–synchronization. Our results are illustrated in the model SQUID and Rössler oscillator systems.

The growing context-sensitive languages have been classiied through the shrinking two-pushdown automaton, the deterministic version of which characterizes the class of generalized Church-Rosser languages (Buntrock and Otto 1995). Exploiting this characterization we prove that this latter class coincides with the class of Church-Rosser languages that was introduced by McNaughton, Narendran, and ...

Otto Heinrich Warburg (1883-1970; not to be confused with the Zionist of the same name) was a member of an illustrious Jewish family, known for some five centuries. From humble beginnings, the family became prominent in the world for their contributions to all aspects of society. The son of a German mother and a Jewish (converted) father, Otto H. Warburg became a major contributor to medical sc...
