TL;DR: In this article, the equations of coupled-pair many-electron theory (CPMET) were extended to incorporate the effect of both unlinked and linked triexcited clusters, and the minimal basis correlation energy of the B${\mathrm{H}}_{3}$ molecule in the ground state was calculated using the ordinary as well as extended CPMET in various degrees of approximation.
Abstract: The equations of the coupled-pair many-electron theory (CPMET) are extended to incorporate the effect of both unlinked and linked triexcited clusters. The minimal basis correlation energy of the B${\mathrm{H}}_{3}$ molecule in the ground state is calculated using the ordinary as well as extended CPMET in various degrees of approximation, and the relative importance of linked and unlinked triexcited clusters is studied. The results afford an unambiguous conclusion for closed-shell systems that, in contrast to the situation with tetraexcited states, unlinked triexcited clusters are negligible relative to the linked ones. It is shown that the extended CPMET reproduces the full configuration-interaction results to a very high degree of accuracy.

TL;DR: In this article, a general formalism for theories which preserve the relativity of inertial frames with a nonlinear action of the Lorentz transformations on momentum space is presented, which leads also to a maximum momentum and a speed of light that diverges with energy.
Abstract: The hypothesis that the Lorentz transformations may be modified at Planck scale energies is further explored. We present a general formalism for theories which preserve the relativity of inertial frames with a nonlinear action of the Lorentz transformations on momentum space. Several examples are discussed in which the speed of light varies with energy and elementary particles have a maximum momenta and/or energy. Energy and momentum conservation are suitably generalized and a proposal is made for how the new transformation laws apply to composite systems. We then use these results to explain the ultrahigh-energy cosmic ray anomaly and we find a form of the theory that explains the anomaly, and leads also to a maximum momentum and a speed of light that diverges with energy. We finally propose that the spatial coordinates be identified as the generators of translation in Minkowski spacetime. In some examples this leads to a commutative geometry, but with an energy dependent Planck constant.

TL;DR: A whole-body inverted pendulum model was used to investigate the control of balance and posture in the frontal plane during human walking and interactions between the supporting foot and hip musculature to permit variability in strategies used to maintain balance were identified.
