83Compartmental models in epidemiology — In order to model the progress of an epidemic in a large population, comprising many different individuals in various fields, the population diversity must be reduced to a few key characteristics which are relevant to the infection under… …
84Stochastic resonance — (also known as SR) is observed when noise added to a system improves the systems performance in some fashion. More technically, SR occurs if the signal to noise ratio of a nonlinear system or device increases for moderate values of noise… …

86Superlens — A superlens, super lens or perfect lens is a lens which uses metamaterials to go beyond the diffraction limit. The diffraction limit is an inherent limitation in conventional optical devices or lenses.[1] In 2000, a type of lens was proposed,… …
87Temporal theory (hearing) — The temporal theory of hearing states that our perception of sound depends on the temporal patterns with which neurons respond to sound in the cochlea. Therefore, the pitch of a pure tone would be determined by period of neuron firing patterns,… …
