In other words, two anatomical complexes can have highly similar matrices but be of greatly differing absolute sizes.
This strong phylogenetic signal will result in a large Pearson correlation of the distance matrices, but is not strong evidence for functional coevolution.
Now, Niklason and her team have developed a potential alternative in which donor cells are used to create a collagen matrix but are then removed, so the final product is acellular.
Strength and flexibility are important, but even more an adequate porosity, so the chondrocytes can migrate through the matrix, but are not able to float around.
Their properties are not only dependent on the properties of the filler and matrix, but are also determined by their interaction.
These variants are related by those symmetry operations which belong to the B2 matrix but are lost in the precipitate phase.
On the design, technical, and traditional tech and digital roles we are highly matrixed, but are internally starting to cross-train people into different roles.
In system state, matrix dimensions are homogenized by adding as many zeros as needed (these additional zeros allow the mathematical treatment of the system state matrix but are ignored in the decision-making algorithms).
The airway basal cells directly interact with the extracellular matrix, but are also capable of extending elements to sample the airway epithelial surface, and are adept at migrating into injured areas [4], [50], [51].
