On the relationship between parametric two-electron reduced-density-matrix methods coupled electron pair approximation
font style='font-size:12px;'>
2010/12/15
Parametric two-electron reduced-density-matrix (p-2RDM) methods have enjoyed much success
in recent years; the methods have been shown to exhibit accuracies greater than coupled cluster
with single ...
Hypolimnetic oxygen consumption by sediment-based reduced substances in former eutrophic lakes
Hypolimnetic oxygen consumption sediment-based reduced substances former eutrophic lakes

2014/4/16
We quantified the areal hypolimnetic mineralization rate (AHM; total areal hypolimnetic oxygen depletion including the formation of reduced substances) in two formerly eutrophic lakes based on 20 yr o...
Derivation of reduced two-dimensional fluid models via Dirac's theory of constrained Hamiltonian systems
two-dimensional fluid models Dirac's theory Hamiltonian systems
font style='font-size:12px;'>
2010/4/1
We present a Hamiltonian derivation of a class of reduced plasma two-dimensional fluid models, an example being the Charney-Hasegawa-Mima equation. These models are obtained from the same parent Hamil...

We present velocity observations of a glacier outlet in Vatnajökull, Iceland, deduced from interferometric SAR (InSAR) data obtained during the ERS1/2 tandem mission in 1995–2000. More than a 50%...
On resonant interactions of ions with plasma waves in a reduced quasi-linear theory
resonant interactions of ions plasma waves reduced quasi-linear theory
font style='font-size:12px;'>
2009/11/12
Based on quasi-linear theory (involving pitch angle scattering), the resonant interactions between ions and waves in an anisotropic multi-component plasma are discussed. In particular, electromagnetic...
