DNA cyclization and looping in the wormlike limit: normal modes and the validity of the harmonic approximation [PDF]

, 2015
For much of the last three decades Monte Carlo-simulation methods have been the standard approach for accurately calculating the cyclization probability, $J$, or J factor, for DNA models having sequence-dependent bends or inhomogeneous bending ...

The effect of host structure on the selectivity and mechanism of supramolecular catalysis of Prins cyclizations. [PDF]

, 2015
The effect of host structure on the selectivity and mechanism of intramolecular Prins reactions is evaluated using K12Ga4L6 tetrahedral catalysts. The host structure was varied by modifying the structure of the chelating moieties and the size of the ...
