  2. Quasicrystal - Wikipedia

    en.wikipedia.org/wiki/Quasicrystal

    Bohr showed that quasiperiodic functions arise as restrictions of high-dimensional periodic functions to an irrational slice (an intersection with one or more hyperplanes), and discussed their Fourier point spectrum. These functions are not exactly periodic, but they are arbitrarily close in some sense, as well as being a projection of an ...

  3. Living systems - Wikipedia

    en.wikipedia.org/wiki/Living_systems

    Complex systems biology is a field of science that studies the emergence of complexity in functional organisms from the viewpoint of dynamic systems theory. [20] The latter is also often called systems biology and aims to understand the most fundamental aspects of life.

  4. Biological system - Wikipedia

    en.wikipedia.org/wiki/Biological_system

    The notion of system (or apparatus) relies upon the concept of vital or organic function: [2] a system is a set of organs with a definite function. This idea was already present in Antiquity (Galen, Aristotle), but the application of the term "system" is more recent.

  5. Function (biology) - Wikipedia

    en.wikipedia.org/wiki/Function_(biology)

    In evolutionary biology, function is the reason some object or process occurred in a system that evolved through natural selection.That reason is typically that it achieves some result, such as that chlorophyll helps to capture the energy of sunlight in photosynthesis.

  6. Quasiperiodicity - Wikipedia

    en.wikipedia.org/wiki/Quasiperiodicity

    Climate oscillations that appear to follow a regular pattern but which do not have a fixed period are called quasiperiodic. [3] [4]Within a dynamical system such as the ocean-atmosphere system, oscillations may occur regularly when they are forced by a regular external forcing: for example, the familiar winter-summer cycle is forced by variations in sunlight from the (very close to perfectly ...

  8. Biological material - Wikipedia

    en.wikipedia.org/wiki/Biological_material

    Biotic material, natural material, or natural product, a material produced by a living organism; Biomass, living or dead biological matter, often plants grown as fuel; Biomass (ecology), the total mass of living matter in a given environment, or of a given species; Body fluid, any liquid originating from inside the bodies of living people

  9. Systems biology - Wikipedia

    en.wikipedia.org/wiki/Systems_biology

    Systems biology can be considered from a number of different aspects. As a field of study, particularly, the study of the interactions between the components of biological systems, and how these interactions give rise to the function and behavior of that system (for example, the enzymes and metabolites in a metabolic pathway or the heart beats).
