21. This exponential decay is related to the motion of the particles, specifically to the diffusion coefficient. 22. Figure 1 represents a fundamental macroscale model : capital in economics or exponential decay in physics. 23. The emission in both curves then peaks at around 60 seconds before a long exponential decay . 24. But the attenuation is not an exponential decay . 25. This is the form of the equation that is most commonly used to describe exponential decay . 26. Intuitively, an exponential decay model seems most suitable: 27. In simple cases, an exponential decay is measured which is described by the T 2 time. 28. The DNA degrades in an exponential decay process. 29. In a characteristic pore containing for an example, water, the bulk water exhibits a single exponential decay . 30. In simple cases, an exponential decay is measured, which is described by the T _ 2 time.
