We first quantified the propagation direction and speed of the detected waves. The voltage waves propagated in preferred directions in all three brain state conditions, but the wave directions showed a broader distribution in the post woken and fully awake states than in the anesthetized condition (...
the waveforms shown in Fig.3B as a function of depth,z, were Fourier transformed to obtain the amplitudes as a function of wavenumber,k, which is related to speed as follows:\(v_{s} = (k\Delta t)^{ - 1}\), where\(\Delta t\)is the time interval of the micropulses. Figure4A...

The key contributions of this paper are: developing a GPU-based high-speed implementation capable of processing H–S wavefront sensor images; creating a robust and accurate centroid detection algorithm based on dynamic pyramidal search; implementing a highly-parallel pupil tracking algorithm for Hartmann...

In addition to increasing the bias voltage and downscaling the depletion layer thickness as dis- cussed above, the most attractive way to further improve the saturation current without sacrificing the speed performance of the photodiode is to increase the carrier drift velocity (see equation (1))....
To satisfy the requirements of calculation speed, correctness, and memory, we optimized the mesh by using 15 cells per wavelength (both near and far from the object) and divided the maximum cell size by 15 to define a minimum cell size. A singularity model was used for the PEC. The ...
