Journal ArticleDOI
A Mitogen-Activated Protein Kinase Cascade Module, MKK3-MPK6 and MYC2, Is Involved in Blue Light-Mediated Seedling Development in Arabidopsis
TL;DR: This work shows that the MKK3-MPK6 is activated by blue light in a MYC2-dependent manner during Arabidopsis seedling development and provides a revised mechanistic view of photomorphogenesis.
Journal ArticleDOI
A state-specific approach to multireference coupled electron-pair approximation like methods: development and applications.
TL;DR: A suite of physically motivated coupled electron-pair approximations (SS-MRCEPA) like methods, which are designed to capture the essential strength of the parent SS-MRCC method without significant sacrificing its accuracy, are suggested and explored.
Journal ArticleDOI

TL;DR: Comparisons with FCI and CC calculations show that in most cases the effective valence shell Hamiltonian (H(v) method is more accurate than other low-order multireference perturbation theories, although none of the perturbative methods is as accurate as the CC approximations.
Journal ArticleDOI
Development of a linear response theory based on a state-specific multireference coupled cluster formalism
TL;DR: In this paper, a linear response theory based on state-specific multireference coupled cluster (SS-MRCC) method is proposed to compute excited state energies for systems whose ground state has a pronounced multiresference character, and is designed to treat quasidegeneracy of varying degrees while bypassing the intruder problem.
Journal ArticleDOI
Molecular applications of state-specific multireference perturbation theory to HF, H2O, H2S, C2, and N2 molecules
TL;DR: Numerical investigations demonstrate that the SS-MRPT(MP) approach provides a balanced treatment of dynamical and non-dynamical correlations across the entire PECs of the systems considered.
