Relating phonetic and phonological categories [chapter]

Andreas Kornai
1994 Language Computations  
The paper solves the technical problem by i n troducing a notion of homomorphisms.  ...  First, the operation of concatenation is de ned in the usual way for strings and as'continuation' for continuous scalar-vector functions with nite support, and the set of phonetic representations is equipped  ...  Finally, for want of an empirically testable alternative, theories of central processing generally assume that speech recognition is simply the converse of speech synthesis.  ...

Mycorrhizal type determines the magnitude and direction of root-induced changes in decomposition in a temperate forest

Edward R. Brzostek, Danilo Dragoni, Zachary A. Brown, Richard P. Phillips
2015 New Phytologist  
Our findings indicate that root-induced changes in soil processes depend on forest composition, and that shifts in the distribution of AM and ECM trees owing to climate change may determine soil C gains  ...  We hypothesized that decreases in belowground C supply would have stronger effects in plots dominated by ectomycorrhizal (ECM) trees rather than arbuscular mycorrhizal (AM) trees.  ...  Funding was provided by the US Department of Energy-Office of Biological and Environmental Research-Terrestrial Ecosystem Science Program and by the US National Science Foundation (DEB, Ecosystem Studies  ...
