Biochemical investigation of protein phosphorylation events is limited by inefficient production of the phosphorylated and non-phosphorylated forms of full-length proteins. Here using a genomically recoded strain of E. coli with a flexible UAG codon we produce site-specific serine- or phosphoserine-containing proteins, with purities approaching 90%, from a single recombinant DNA. Specifically, ...
In this paper, we present a derivative-based, functional recognizer and parser generator for visibly pushdown grammars. The generated accepts ambiguous grammars produces parse forest containing all valid trees an input string in linear time. Each tree the can then be extracted also Besides generator, to allow more flexible forms of grammars, translator that converts tagged CFG grammar sound way...
To determine whether an industry exhibits constant returns to scale, whether the production fUnction is homothetic, or whether inputs are separabl~ a common approach is to specify a cost function, estimate its parameters using data such as prices and quantities of inputs, and then test the parametric restrictions corresponding to constant returns, a homothetic technology, or separability. Stati...
