Zero-lag phase synchronization of EEG activity has been reported to be a central mechanism accompanying long-term memory formation. In this pilot study, we examined the effects of synchronous low-amplitude stimulation of the rhinal cortex and the hippocampus in eleven temporal lobe epilepsy patients. The impact of in-phase stimulation (zero lag) on long-term memory encoding of words was contras...
We determine the intrinsic phase lag of the GOLF data for the solar p-mode velocity deduced either from one of the narrow band photometers working alternatively on blue and red wing of the sodium lines. The timing of the “blue wing” velocity coming from the current GOLF data is given in respect to the ground-based observations. The phase lag for the “blue” velocity is 6 s in advance relatively ...
Introduction: Direction and latency of electrical connectivity between different sites of brain explains brain neural functionality. We compared efficiency of cross correlation and phase locking methods in time lag estimation which are based on local field potential (LFP) and LFPspike signals, respectively. Methods: Signals recorded from MT area of a macaque’s brain was used in a simulation ...
We consider source coding with fixed lag side information at the decoder. We focus on the special case of perfect side information with unit lag corresponding to source coding with feedforward (the dual of channel coding with feedback) introduced by Pradhan [8]. We use this duality to develop a linear complexity algorithm which achieves the rate-distortion bound for any memoryless finite alphab...
When applying feedback control in active noise control, phase lag caused by transducer dynamics and time delay between microphones and noise sources limits the bandwidth of the controller considerably. The proposed method to increase stability is to compensate the phase lag by applying a Smith compensator. The compensator needs a model of the acoustic plant. As model, only the transducer dynami...
In order to make use of and exploit commercially biodegradable protein-based materials, degradation research is essential to provide information pertinent to the basic production and handling properties of such materials. It seems that the experimental methods utilized to evaluate the lag phases of protein films may be applied to other substrates under various conditions. Techniques used to det...
