Defining laser-beam power density. 2. Power spectral density is simply the Fourier transform of the signal. When we have a discrete case, as in Figure 2, the PSD can be calculated by using the fast ...
Fluctuation spectra of large random dynamical systems reveal hidden structure in ecological networks
Understanding the relationship between complexity and stability in large dynamical systems—such as ecosystems—remains a key open question in complexity theory which has inspired a rich body of work ...
Single-particle tracking offers detailed information about the motion of molecules in complex environments such as those encountered in live cells, but the interpretation of experimental data is ...
