  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 ...

  3. Spectral density estimation - Wikipedia

    en.wikipedia.org/wiki/Spectral_density_estimation

    Spectrum analysis, also referred to as frequency domain analysis or spectral density estimation, is the technical process of decomposing a complex signal into simpler parts. As described above, many physical processes are best described as a sum of many individual frequency components.

  5. Heteronuclear single quantum coherence spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Heteronuclear_single...

    The backbone amide peaks of glycine normally appear near the top of the spectrum. The 15 N HSQC is normally the first heteronuclear spectrum acquired for the assignment of resonances where each amide peak is assigned to a particular residue in the protein. If the protein is folded, the peaks are usually well-dispersed, and most of the ...

  6. Singular spectrum analysis - Wikipedia

    en.wikipedia.org/wiki/Singular_spectrum_analysis

    Singular spectrum analysis applied to a time-series F, with reconstructed components grouped into trend, oscillations, and noise. In time series analysis, singular spectrum analysis (SSA) is a nonparametric spectral estimation method.

  7. Time-resolved spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Time-resolved_spectroscopy

    In physics and physical chemistry, time-resolved spectroscopy is the study of dynamic processes in materials or chemical compounds by means of spectroscopic techniques.Most often, processes are studied after the illumination of a material occurs, but in principle, the technique can be applied to any process that leads to a change in properties of a material.

  8. Bartlett's method - Wikipedia

    en.wikipedia.org/wiki/Bartlett's_method

    [2] [3] A final estimate of the spectrum at a given frequency is obtained by averaging the estimates from the periodograms (at the same frequency) derived from non-overlapping portions of the original series. The method is used in physics, engineering, and applied mathematics. Common applications of Bartlett's method are frequency response ...

  9. Mass spectrum - Wikipedia

    en.wikipedia.org/wiki/Mass_spectrum

    A mass spectrum is a histogram plot of intensity vs. mass-to-charge ratio (m/z) in a chemical sample, [1] usually acquired using an instrument called a mass spectrometer. Not all mass spectra of a given substance are the same; for example, some mass spectrometers break the analyte molecules into fragments ; others observe the intact molecular ...
