We describe a stochastic coupled cluster theory which represents excitation amplitudes as discrete excitors in the space of excitation amplitudes. Reexpressing the coupled cluster (CC) equations as the dynamics of excitors in this space, we show that a simple set of rules suffices to evolve a distribution of excitors to sample the CC solution and correctly evaluate the CC energy. These rules ar...

In this work, a finite element formulation for size dependent frame system is presented. Size dependency discussed via the modified couple stress theory. The nodal displacement and rotation analyses of with total three elements, including two columns one beam connecting these columns, are considered. classical stiffness matrices derived. Then, solution procedure problem explained. Lastly, numer...

Class B G-protein-coupled receptors are exciting drug targets, yet the structure of a complete receptor bound to a peptide agonist has remained elusive. Coin et al. present a model of the receptor CRF1R bound to its native ligand based on partial structures and 44 spatial constraints revealed by new crosslinking approaches.

ABSTRACT-This paper aims to develop a new design of a bentleg (BL) plow and to determine its performance as compared to the conventional one using finite element approach. The difference between the modified and conventional BL plows is the direction of angle between the projection of cutting blade on horizontal plane normal to plow shank and the line perpendicular to the plow shank in the same...

To achieve better precision in describing contaminant dispersion in channels some authors resort to dividing a channel into two zones, fast and slow, leading to a pair of coupled evolution equations for cross-sectionally-averaged concentrations in the zones. We construct a two-zone model whose accuracy is guaranteed by centre manifold theory. The model leads to evolution equations that differ f...
