Ioana, J. Peterson, S. Popa, Amalgamated free products of w-rigid factors and calculation of their symmetry group, math.OA/0505589, Acta Math., in press] applying Popa's deformation/rigidity techniques to amalgamated free product von Neumann algebras.
And the union wage structure is a rigid cost factor in the economy, moving always in just one direction—up.
One of the big weaknesses I think e-readers have right now is their rigid form factor.
DOI: http://dx.doi.org/10.7554/eLife.01345.012 Following refinement that included the use of electron scattering factors, rigid body, simulated annealing, and B-factor refinement, a solution was found with acceptable statistics (Rwork/Rfree = 25.5%/27.8%) and good geometry at 2.9 Å resolution (Table 1).
In PCA, the orthogonality of the factors is rigid and can result in having negative values on the factors restricting its interpretability.
In the range from 88 to 100 bp, J factors with rigid LacR tetramers are lower than those with flexible tetramer assemblies.
Starch granules are relatively rigid structures and several factors, such as the crystalline structure, presence of cracks and pores, and the granule sizes contribute to the relative resistance of granules to enzymatic degradation (Heitmann et al. 1997; Kong et al. 2003; Tester et al. 2004).
The problem, Schnapp says, is BLseasonalnal rigid assessment doesn't factor in these changes and probably overestimated the seasonal hirings.
Indeed, the fluoroprolines are well defined and characterized by low B-factors indicating rigid local conformations in the protein matrix.
Trap has helped minimize these factors with a rigid system.
A procedure is proposed for probabilistic evaluation of load combinations and load factors for steel rigid frame piers at ultimate limit state with collapse mechanism.
