While there have been many reports of plasticity among CD4 T cell subsets, the data still points to a fair level of rigidity among Th1 and Th2 subsets, compared, for example, to Th17 and Treg subsets.
In response to the rigidity problem, Searle points out that intuitions of rigidity are easily enough accommodated: one can simply rigidify the reference-fixing description.
From a psychological point of view, Christian's rigidity (meaning lack of flexibility to do other things) and his obsessive need to only do sadistic acts is suggestive of his psychological material.
The following definition of rigidity of a point process is due to Ghosh [6] (cf. also Ghosh and Peres [7]).
While the handful of classical combinatorial characterizations of rigidity focus on distance constraints between points, this is the first result simultaneously addressing coincidence, angular, and distance constraints.
Adoption of the mandible as a rigid element is justified from the point of view of model tests, as its rigidity in comparison to muscle stiffness is much greater.
The results are discussed from the lightweight, rigidity and fatigue point of view.
Our results show that enzymes are remarkably heterogeneous objects from a mechanical point of view and that the local rigidity of individual residues is tightly connected to their part in the protein's overall structure and function.
We need to fear and temper that kind of rigidity.
Turgor is the cause of rigidity in living plant tissue.
