This review covers a spectrum of optoelectronic properties of and uses for semi-insulating
semiconductor heterostructures and thin films, including epilayers and quantum wells. …

In the past decade, extracellular vesicles (EVs) have been recognized as potent vehicles of
intercellular communication, both in prokaryotes and eukaryotes. This is due to their capacity …

Hybridization has many and varied impacts on the process of speciation. Hybridization may
slow or reverse differentiation by allowing gene flow and recombination. It may accelerate …
