At basal cognitive assessment, the VMPT learning scores and Stroop test interference time were significantly poorer in the PNES patient group compared with the control group (p=0.023, p=0.026).
In the patients with PNES, significant correlations were obtained between disease duration and the VMPT immediate learning score and Stroop test interference time (r=-0.628, p=0.003, r=-0.520, p=0.19).

To determine [d.sub.ACK_Drought], our study introduces the notion of the minimum PU interference time defined as the length of time during which the TCP sender cannot avoid experiencing transmission blockage due to CR characteristics.
[d.sub.ACK_Drought] = max (the minimum PU interference time, one-half the RTT) (1)
Hence, small deviations in the measured strains in this range, as well as variations in PE resins, can lead to significant differences in the estimated interference time. Therefore, caution must be exercised when trying to establish estimates for the interference time for strains that are small compared to maximum percent reduction in the liner diameter.
Knowing how long it takes the rollers to reduce the diameter of the liner by AD (i.e., [t.sub.1]) enables estimating the interference time.
In the case of asynchronous inter-channel spectrum sensing, regarding the same PU channel conditions, passive DSA would risk the PU suffering more interference compared to synchronous DSA, which can be illustrated by the average interference time. Moreover, since the spectrum sensing is usually erroneous, erroneous spectrum sensing should be considered.
For synchronous DSA, the average interference time for delivering a small packet with length dt on channel k can be written as,
With this scheme, the possible interference time to the primary user can be limited to a two-slot time.
The interference time from a single CR node is for transmitting E_NOTI and E_ACK messages (two slot times).
Additionally,  proposes an interference time
ratio-based opportunistic spectrum access method.
