OBJECTIVES The physiologic relationship between slow-wave activity (SWA) (0-4 Hz) on the electroencephalogram (EEG) and high-frequency (0.1-0.4 Hz) cardiopulmonary coupling (CPC) derived from electrocardiogram (ECG) sleep spectrograms is not known. Because high-frequency CPC appears to be a biomarker of stable sleep, we tested the hypothesis that that(More)
BACKGROUND The multi-mode modulation is a key feature of sleep EEG. And the short-term fractal property reflects the sympathovagal modulation of heart rate variability (HRV). The properties of EEG and HRV strongly correlated with sleep status and are interesting in clinic diagnosis. NEW METHOD 19 healthy female subjects were included for over-night(More)
AIMS Accurate ventricular fibrillation (VF) waveform analysis usually requires rescuers to discontinue cardiopulmonary resuscitation (CPR). However, prolonged "hands-off" time has a deleterious impact on the outcome. We developed a new filter technique that could clean the CPR artifacts and help preserve the shockability index of VF METHODS: We analyzed(More)
The Web contains an enormous quantity of information which is usually formatted for human users. This makes it difficult to extract relevant content from various sources. In the last few years some authors have addressed the problem to convert Web documents from unstructured or semi-structured format into structured and therefore machine-understandable(More)
Transfer function analysis (TFA) is a frequently used method to assess dynamic cerebral autoregulation (CA) using spontaneous oscillations in blood pressure (BP) and cerebral blood flow velocity (CBFV). However, controversies and variations exist in how research groups utilise TFA, causing high variability in interpretation. The objective of this study was(More)
This work presents our verification methodology from architecture to RTL design. There are three major benefits of the proposed verification methodology. First, this methodology enables the verification task to start at architecture design stage even without the implementation details. Second, the verification framework is well-organized and suitable for(More)
