Drude model for collective oscillation of free electrons, Lorentz model for local resonance of electric dipoles, and Debye model for relaxation process of dipole orientation. In contrast ...

Our approach uses two broadband semiconductor lasers with chaotic intensity oscillations. The output intensity of each laser is converted to an a.c. electrical signal by photodetectors ...

These oscillations help pump cerebrospinal fluid ... as blue light can disrupt melatonin production. 3. Practice Relaxation Techniques: Activities like meditation, deep breathing, or yoga can ...
