A composition of birational maps given by Laurent polynomials need not be given by Laurent polynomials; however, sometimes—quite unexpectedly—it does. We suggest a unified treatment of this phenomenon, which covers a large class of applications. In particular, we settle in the affirmative a conjecture of D. Gale and R. Robinson on integrality of generalized Somos sequences, and prove the Lauren...

As computer graphics matures, data is becoming a driving force of increased importance in this progress due to its large quantity and disparateness. Visualization, a domain in computer graphics, is specifically centered around the problem of data-dependent understanding and representation. However, since data is always imperfect, additional assumptions and information are required in order to p...

Complex systems share a unique and fascinating property: they exhibit emergence, a process that, over time, gives rise to novel structures (e.g. behaviors, features) that are produced by but irreducible to the low-level mechanisms that govern the system (Holland, 1988, 2000). The complexity paradigm proposes that understanding emergent properties requires a shift in focus, from the unique chara...

− The results of exact time domain analysis of the switched-mode tuned Class E power amplifiers with a quarterwave transmission line are presented with analytical determination of the optimum load network parameters. Effects of the quarterwave transmission line and collector capacitance on the current and voltage waveforms are discussed and analyzed. The ideal collector voltage and current wave...
متن کاملSeymour Benzer 1921–2007
It is now common knowledge that both “Nature” and “Nurture” determine animal behavior. But even as late as the 1970s, the concept that genes have anything to do with behavior was not universally accepted. In the face of such skepticism, Seymour Benzer, working tirelessly at Caltech, refused to join the philosophical debate and, in the way so familiar to those who knew him, shrugged his shoulder...
