  2. Cell potency - Wikipedia

    en.wikipedia.org/wiki/Cell_potency

    Cell potency is a cell's ability to differentiate into other cell types. [1] [2] The more cell types a cell can differentiate into, the greater its potency.Potency is also described as the gene activation potential within a cell, which like a continuum, begins with totipotency to designate a cell with the most differentiation potential, pluripotency, multipotency, oligopotency, and finally ...

  4. Cellular differentiation - Wikipedia

    en.wikipedia.org/wiki/Cellular_differentiation

    Three basic categories of cells make up the mammalian body: germ cells, somatic cells, and stem cells.Each of the approximately 37.2 trillion (3.72x10 13) cells in an adult human has its own copy or copies of the genome except certain cell types, such as red blood cells, that lack nuclei in their fully differentiated state.

  5. Matter power spectrum - Wikipedia

    en.wikipedia.org/wiki/Matter_power_spectrum

    The matter power spectrum describes the density contrast of the universe (the difference between the local density and the mean density) as a function of scale. It is the Fourier transform of the matter correlation function .

  6. Dedifferentiation - Wikipedia

    en.wikipedia.org/wiki/Dedifferentiation

    This definition is important to consider when discussing dedifferentiation because the two concepts overlap closely, such that metaplasia may rely on dedifferentiation, or they may share similar pathways. Metaplasia, however, aligns more closely with transdifferentiation, because metaplasia refers more to the idea of a phenotypic transition.

    Gottlieb Haberlandt (28 November 1854 – 30 January 1945) was an Austrian botanist.He was the son of European 'soybean' pioneer Professor Friedrich J. Haberlandt. [1] His son Ludwig Haberlandt was an early reproductive physiologist now given credit as the 'grandfather' of the birth control pill.

  8. Decomposition of spectrum (functional analysis) - Wikipedia

    en.wikipedia.org/wiki/Decomposition_of_spectrum...

    By definition, a complex number λ is in the spectrum of T, denoted σ(T), if T − λ does not have an inverse in B(X). If T − λ is one-to-one and onto , i.e. bijective , then its inverse is bounded; this follows directly from the open mapping theorem of functional analysis.

  9. Stellar classification - Wikipedia

    en.wikipedia.org/wiki/Stellar_classification

    The spectrum of a class M star contains lines from oxide molecules (in the visible spectrum, especially TiO) and all neutral metals, but absorption lines of hydrogen are usually absent. TiO bands can be strong in class M stars, usually dominating their visible spectrum by about M5. Vanadium(II) oxide bands become present by late M.
