  2. Dominance signal - Wikipedia

    en.wikipedia.org/wiki/Dominance_signal

    Visual communication is a common dominance signal among animals. They are an effective modality as they come at a low cost to the animal and minimize risk. The Gila Monster (Heloderma suspectum) for example, express bright orange splotches during territorial conflict to warn competitors that they are poisonous, and thus assert their dominance over a territory.

  3. Signal - Wikipedia

    en.wikipedia.org/wiki/Signal

    Signal refers to both the process and the result of transmission of data over some media accomplished by embedding some variation. Signals are important in multiple subject fields including signal processing, information theory and biology. In signal processing, a signal is a function that conveys information about a phenomenon.

  4. Discrete-time Fourier transform - Wikipedia

    en.wikipedia.org/wiki/Discrete-time_Fourier...

    In both cases, the dominant component is at the signal frequency: = / =. Also visible in Fig 2 is the spectral leakage pattern of the = rectangular window. The illusion in Fig 3 is a result of sampling the DTFT at just its zero-crossings. Rather than the DTFT of a finite-length sequence, it gives the impression of an infinitely long sinusoidal ...

  5. Signalling theory - Wikipedia

    en.wikipedia.org/wiki/Signalling_theory

    By stotting (also called pronking), a springbok (Antidorcas marsupialis) signals honestly to predators that it is young, fit, and not worth chasing.. Within evolutionary biology, signalling theory is a body of theoretical work examining communication between individuals, both within species and across species.

  6. Ocular dominance column - Wikipedia

    en.wikipedia.org/wiki/Ocular_dominance_column

    Ocular dominance columns were discovered in the 1960s by Hubel and Wiesel as part of their Nobel prize winning work on the structure of the visual cortex in cats.Ocular dominance columns have since been found in many animals, such as ferrets, macaques, and humans. [2]

  7. Phase (waves) - Wikipedia

    In the adjacent image, the top sine signal is the test frequency, and the bottom sine signal represents a signal from the reference. If the two frequencies were exactly the same, their phase relationship would not change and both would appear to be stationary on the oscilloscope display.

  8. Dominator (graph theory) - Wikipedia

    en.wikipedia.org/wiki/Dominator_(graph_theory)

    In computer science, a node d of a control-flow graph dominates a node n if every path from the entry node to n must go through d. Notationally, this is written as d dom n (or sometimes d ≫ n). By definition, every node dominates itself. There are a number of related concepts: A node d strictly dominates a node n if d dominates n and d does ...

  9. Cell signaling - Wikipedia

    en.wikipedia.org/wiki/Cell_signaling

    Complex multi-component signal transduction pathways provide opportunities for feedback, signal amplification, and interactions inside one cell between multiple signals and signaling pathways. [citation needed] A specific cellular response is the result of the transduced signal in the final stage of cell signaling.
