Deciphering Growth (Research and Perspectives in Endocrine Interactions)
An organism’s body size tells us a lot about how it makes a living, suggesting that
body size is a key parameter in evolution. We outline three large-scale trends in
body size evolution. Bergmann’s Rule is the tendency for warm-blooded species
at high latitudes to be larger than their close relatives nearer the equator.... Semiconductor Lasers I: Fundamentals (Optics and Photonics) (Pt. 1) More than three decades have passed since lasing in semiconductors was first observed in several laboratories in 1962 (Hall et al., 1962; Holonyak, Jr. et al., 1962; Nathan et al., 1962; Quist et al., 1962). Although it was one of the first lasers to be demonstrated, the semiconductor laser had to await several important developments, both...
