1. In particular, percolation networks exhibit a phase change around a critical threshold . 2. In this case, for large scale-free networks, the critical threshold approaches 1. 3. There's a critical threshold of decay beyond which body parts do not regenerate. 4. Finally, a critical threshold was reached, and temperature soared, producing a sudden hothouse. 5. Neurons produce action potentials when their membrane potential increases past a critical threshold . 6. Should an American intelligence agency cross that critical threshold ? 7. However, above a critical threshold , increased density reduces speed. 8. They crossed a critical threshold this weekend, a limit beyond what they can take anymore. 9. The critical threshold is reached only in the winter. 10. He was involved in ground-breaking work on kinetic theories and critical thresholds phenomena in nonlinear transport models.
