  2. Endomicroscopy - Wikipedia

    en.wikipedia.org/wiki/Endomicroscopy

    Endomicroscopy is a technique for obtaining histology-like images from inside the human body in real-time, [1] [2] [3] a process known as ‘optical biopsy’. [ 4 ] [ 5 ] It generally refers to fluorescence confocal microscopy , although multi-photon microscopy and optical coherence tomography have also been adapted for endoscopic use.

  3. Confocal endoscopy - Wikipedia

    en.wikipedia.org/wiki/Confocal_endoscopy

    Confocal endoscopy, or confocal laser endomicroscopy (CLE), is a modern imaging technique that allows the examination of real-time microscopic and histological features inside the body. In the word "endomicroscopy", endo- means "within" and -skopein means "to view or observe".

  5. Spin contamination - Wikipedia

    en.wikipedia.org/wiki/Spin_contamination

    In computational chemistry, spin contamination is the artificial mixing of different electronic spin-states. This can occur when an approximate orbital-based wave function is represented in an unrestricted form – that is, when the spatial parts of α and β spin-orbitals are permitted to differ. Approximate wave functions with a high degree ...

    en.wikipedia.org/wiki/R-factor_(crystallography)

    If the two statistics differ significantly then that indicates the model has been over-parameterized, so that to some extent it predicts not the ideal error-free data for the correct model, but rather the error-afflicted data actually observed.

  7. Pump–probe microscopy - Wikipedia

    en.wikipedia.org/wiki/Pump–probe_microscopy

    Two-photon absorption (TPA) is a third-order process in which two photons are nearly simultaneously absorbed by the same molecule. If a second photon is absorbed by the same electron within the same quantum event, the electron enters an excited state.

  8. Free-energy perturbation - Wikipedia

    en.wikipedia.org/wiki/Free-energy_perturbation

    Free-energy perturbation (FEP) is a method based on statistical mechanics that is used in computational chemistry for computing free-energy differences from molecular dynamics or Metropolis Monte Carlo simulations. The FEP method was introduced by Robert W. Zwanzig in 1954. [1]
