Understanding the kinetic mechanism of RNA single base pair formation.
RNA functions are intrinsically tied to folding kinetics. The most elementary step in RNA folding is the closing and opening of a base pair. Understanding this elementary rate process is the basis for RNA folding kinetics studies. Previous studies mostly focused on the unfolding of base pairs. Here, based on a hybrid approach, we investigate the folding process at level of single base pairing/s...
متن کاملA linked electron pair functional.
A modification of the variational configuration interaction functional in the first-order interacting space for molecular electronic structure is presented. The modified functional is a fully linked expression that by construction is extensive and invariant to transformations of the underlying orbital basis and is exact for an ensemble of separated two-electron subsystems. In addition, an appro...
متن کاملSpectrophotometric Methods for Determination of Sunitinib in Pharmaceutical Dosage Forms Based on Ion-pair Complex Formation
Three rapid spectrophotometric methods were developed for the determination of sunitinib based on the formation of ion-pair complex in acidic medium with bromocresol purple, bromothymol blue, and bromophenol blue. The formed ion-pair complexes, extractable with chloroform, were measured at 422 nm for bromocresol purple, 425 nm for bromothymol blue and 427 nm for bromophenol blue. All these meth...

متن کاملStrategies for electron pair reconstruction in CBM
The investigation of the inmedium properties of short lived neutral vector mesons (ρ, ω, φ) via detection of their decay in electron-positron pairs is one of the major issues of the CBM physics program. The strategies to reduce the combinatorial background in electron pair measurements with the CBM detector are discussed here. The simulations were performed for the collision system Au+Au at a b...
