PREDISTORTION Linear Power Amplifier Uses Mirror Predistortion

Current wireless c o m m u n i c a t i o n standards have been established to carry voice, data and video with high data rates. These high data rates require efficient modulation techniques such as OFDM 64 QAM, to allow transmission in a given finite bandwidth. With these types of modulation, there are probabilities that at certain times, the voltages of the multiple carriers are in phase and t...

Military Uses of Nanotechnology: Perspectives and Concerns

Could plants have cognitive abilities?

Vegetation is traditionally regarded as passive, doing nothing but what is essential to grow and survive. Evidence is accumulating, however, in support of formerly esoteric notions that plants can communicate, remember, even count--features that one would call cognitive if they were observed in animals. Michael Gross reports.

How Could Language Have Evolved?

The evolution of the faculty of language largely remains an enigma. In this essay, we ask why. Language's evolutionary analysis is complicated because it has no equivalent in any nonhuman species. There is also no consensus regarding the essential nature of the language "phenotype." According to the "Strong Minimalist Thesis," the key distinguishing feature of language (and what evolutionary th...
