Most groups operated on the basis of financial reimbursement per enrolled patient, and the UK model subsequently evolved to a hybrid system for more complex trials.
Very large scale integration (VLSI) technology has evolved to a level where large systems, previously implemented as printed circuit boards with discrete components, are integrated into a single integrated circuit (IC).
The branching structures found in biological systems have evolved to an optimum arrangement that distributes nutrients efficiently in the system.
The guest host system evolved to a nematic phase in approximately 120 ns, which is longer than the time of approximately 75 ns for the E7 host alone (described above).
This system has evolved to a more flexible, modular concept with input from surgeons and engineers.
Their tuning width and sensitivities have evolved to suit a system of a limited number of detectors (ca. 50), perhaps making it more likely a machine replicate of an insect nose can be designed.
For its part, the Ni0.5Co0.5/SBA-15 has initially a catalytic performance similar to the Ni/SBA-15 monometallic system, but rapidly evolving to an inactive system, therefore resembling the behavior of the cobalt-based catalyst.
A general set of conditions by which a puck collection system may be seen to evolve to a one-cluster system is developed.
When the system temperature determined by the initial system energy is negative, the system evolves to a state consisting of many small areas with different temperatures by the violent relaxation.
When the Cahn Hilliard model is used, molecule concentration gradients are sustained, the neck stabilizes and the system evolves to a steady-state with a small, compact vesicle attached to the membrane.
