His eyes were tired, absent of the malicious spark that usually lit them from within.
The SPR is absent for the TE-polarization of light, and formation of the waveguide modes play a key role in this case [15].
Our reconstructions indicate that there was very little heavy tree cover at this site (likely less than 10%), with the palaeo-landscape instead comprising a mixture of light and absent tree cover.
Focal injections of neural tracers reveal the tendency for populations of labeled cells to collectively form patches of labeled somata and excitatory axonal terminals, separated by regions of light or absent label, and covering several millimeters within a cortical area (Rockland and Lund 1981, 1983; Rockland et al. 1982; Lund et al. 2003).
Spiritually, the director Paul Feig's version of the city resembles the backdrop to a late-night talk show, full of lights and absent of people.
Also we note that the effect of light seems to be absent at these higher pH conditions, which could be due to this surface passivation.
If hand movements cannot be identified, the examiner checks for perception of light, which is recorded as present or absent.
Since problems of light scattering, nonselective excitation, and source instability are absent, chemiluminescence possesses an inherently low background, allowing for a very sensitive analysis.
Objects appear coloured when they absorb visible light of certain wavelengths, and those absorbed wavelengths are consequently absent from light that passes from the coloured object to the eyes.
For example, bilateral absent pupillary light responses and corneal reflexes have false positive rates of 0.2 and 0.4 %, respectively, for predicting poor neurological recovery.
