The concept of receptive field is a linear, feed-forward view of visual signal processing. Frequently used models of V1 neurons, like the dynamic Linear filter--static nonlinearity--Poisson [corrected] spike encoder model, predict that receptive fields measured with different stimulus ensembles should be similar. Here, we tested this concept by comparing spatiotemporal maps of V1 neurons derive...

In the first step, the EEG signal from each electrode is converted to the frequency domain using the Fast Hartley Transform. Artifacts in the transformed signal using the frequency domain were removed using a band pass Chebyshev filter such that only frequencies in the range of 5-15 Hz is retained. The minimum energy, maximum energy and the average energy is computed. The computed features are ...

N UTRITIONAL m u s c u l a r d y s t r o p h y (NMD) occurs spontaneously in lambs in many areas (Allaway and Hodgson, 1964; Hartley and Grant, 1961; and Muth, 1963) and can result in substantial economic loss to flock owners. Willman et al. (1945) demonstrated that vitamin E was effective in preventing and curing NMD. However, Muth (1955) and Hartley and Grant (1961) observed that vitamin E ha...

The discrete Hartley transform (DHT) has proved to be a valuable tool in digital signal/image processing and communications and has also attracted research interests in many multidimensional applications. Although many fast algorithms have been developed for the calculation of oneand two-dimensional (1-D and 2-D) DHT, the development of multidimensional algorithms in three and more dimensions i...

Polarized laser photolysis, coupled with resonantly enhanced multiphoton ionization detection of O D2 and velocity-map ion imaging, has been used to investigate the photodissociation dynamics of ozone at 193 nm. The use of multiple pump and probe laser polarization geometries and probe transitions has enabled a comprehensive characterization of the angular momentum polarization of the O D2 phot...

Polarized laser photolysis, coupled with resonantly enhanced multiphoton ionization detection of O(1D2) and velocity-map ion imaging, has been used to investigate the photodissociation dynamics of ozone at 193 nm. The use of multiple pump and probe laser polarization geometries and probe transitions has enabled a comprehensive characterization of the angular momentum polarization of the O(1D2) ...
