Covariance matrices describe the mean-square deviations in atomic coordinates from their mean position (diagonal elements) or the correlations between their pairwise fluctuations (off-diagonal elements).
Once the search of fluctuations is completed, the time position and intensity values of the found fluctuations can be further analyzed for statistics of the fluctuations, e.g., distribution of number of fluctuations over measurement time, distribution of number of fluctuations over photon counts, and distribution of number of fluctuations over time-in-between fluctuations (off-times).
The dynamics that falls into the subset of photons depicted in Fig. 7A was further characterized by its time-dependent fluctuation number distribution in Fig. 7B, and its fluctuation off-time distribution in Fig. 7C.
However, after several years of dopaminergic therapy, most patients experience fluctuations between "off-time" and "on-time" in both motor and non-motor symptoms as much as 2-3 hours a day [ 11].
Finally, the frequency is sufficiently high to avoid excessive fluctuations of the lift-off height and the reattachment to the burner.
Cerebral autoregulation was assessed by Pearson linear regression coefficient (Mx index) between MCA FV and MAP during spontaneous fluctuations of MAP (cut-off of Mx ≥ 0.2 was adopted to define impaired autoregulation).
An analysis of the main principles for the choice of lift-off is described by us and a new method that improves the structure of the detector is proposed from the point of view of the design of a magnetic circuit, to restrain the impact of fluctuations of sensor lift-off.
The simulation results demonstrate the effectiveness of the proposed reconstruction strategy with various downsampling patterns, fluctuation of graph cut-off frequency, robustness on the classic graph structures, and noisy scenarios.
Then, we demonstrate the performance of the proposed algorithm and the current algorithms with various downsampling patterns, fluctuation of graph cut-off frequency, robustness on the classic graph structures, and noisy scenarios.
However, levodopa therapy is eventually complicated by motor fluctuations, including "wearing off" and "on-off" phenomena (Fahn 1999).
Symptomatic treatment with levodopa or dopamine agonists is effective in alleviating these symptoms, although, along with disease progression, levodopa-induced motor complications (e.g. dyskinesias, wearing-off, on-off fluctuations) may appear.
