Mechanism of O-acetylserine sulfhydrylase fromSalmonella typhimurium LT-2
O-Acetylserine sulfhydrylase is a pyridoxal 5′-phosphate (PLP) dependent enzyme that catalyzes the final step of L-cysteine biosynthesis inSalmonella, viz. the conversion of O-acetyl-L-serine (OAS) and sulfide to...

Variational approximations in energy space for the regulator problem with time delay
We consider a variational procedure for approximating the solution of the state regulator problem with time delay. Motivated by a dual formulation of the problem, we introduce a positive-definite functionalF over...

N-Ion Implantation into ZnSe
Low resistivity n-type ZnSe single crystals implanted with 60 keV or 60 and 25 keV N-ions were converted to p-type conductivity after proper annealing. The type conversion was confirmed by a thermal probe meth...
