See Izhikevich [48] for a MATLAB code which determines smooth curves approximating isochrons.
The PDB file of cryo-EM determined smooth muscle α-actinin from chicken gizzard (PDB code 1SJJ; [26]) was used for structural representation of the protein using MolMol [27].
Important events determining smooth muscle cell functions are plasma membrane ion fluxes such as Ca2+ entry (Beech, 2007).
We quantitatively determined smooth muscle-to-endothelial cell ratio in the walls of the tumour edge-associated vessels by measuring the areas occupied by the red colour, which represents endothelial cells, and the areas occupied by the green colour, which represents smooth muscle cells.
It may not be totally appropriate to call the determined smoothed rump functions as fling-step functions, but what we determined here was the best matching smooth function for the observed displacement time history of each component.
In conclusion, this is the first comprehensive study which determines smoothed age- and sex-specific WC, WHR and WHtR percentiles in the Greek population for adolescents aged 12 to 17 years.
The shape sensitivity, called shape gradient function, is theoretically derived using the adjoint variable method and the formula of the material derivative, and then applied to a gradient method with Laplacian smoother for shells to determine the smooth optimal shape.
How all these elements are dealt with will determine how smooth the transition is.
However, the above two terms cannot determine a smooth shape (and sometimes there are infinitely many solutions).
Thus, we can determine a smooth control (phi(t)) from (3.4), which means that condition 2 is satisfied.
