Improved lower bounds for the ground-state energy of many-body systems

, 2001
New lower bounds for the binding energy of a quantum-mechanical system of interacting particles are presented. The new bounds are expressed in terms of two-particle quantities and improve the conventional bounds of the Hall-Post type.

Lack of evidence for central sensitization in idiopathic, non-traumatic neck pain : a systematic review [PDF]

, 2015
Background: Chronic neck pain is a common problem with a poorly understood pathophysiology. Often no underlying structural pathology can be found and radiological imaging findings are more related to age than to a patient's symptoms.

υ-representability of one-body density matrices [PDF]

, 2001
We consider low-dimensional model systems with a fixed two-body interaction and a variable (nonlocal) one-body potential. It is shown explicitly that an extended domain of allowed (N-representable) one-body density matrices cannot be generated in this ...

The Seven Steps of Case Study Development: A Strategic Qualitative Research Methodology in Female Leadership Field [PDF]

This study examines the theme of female leadership as a complex concept and an embedded phenomenon. It is in a feminist paradigm that attempts to give voice to women, and works to correct the imbalance generally posited from a predominantly male oriented

Extensive v2DM study of the one-dimensional Hubbard model for large lattice sizes: Exploiting translational invariance and parity [PDF]

, 2013
Using variational density matrix optimization with two- and three-index conditions we study the one-dimensional Hubbard model with periodic boundary conditions at various filling factors.

Performance of the resurfaced hip. Part 1: the influence of the prosthesis size and positioning on the remodelling and fracture of the femoral neck

, 2010
Hip resurfacing is an established treatment for osteoarthritis in young active patients. Failure modes include femoral neck fracture and prosthesis loosening, which may be associated with medium-term bone adaptation, including femoral neck narrowing and ...
