Timeout active-lever presses per pellet earned during training revealed a significant effect of time (F 3,47) = 14; P<0.001), but not of genotype (F 1,14) = 2; P = 0.24) and no time x genotype interaction (F 3,47) = 3; P = 0.07; Fig. 3D).
Instead of taking a year off to think things through, we now choose an active timeout.
A significant main effect of sex was also found for the number of ineffective nose pokes (nose pokes during the 40-second timeout after each infusion) in the active hole (F1,28 = 6.381, P = 0.017), with bLR females poking more ineffectively on day 1 (P = 0.042) and day 4 (P = 0.039).
It would be useful for the authors to also include lever press data for the sucrose self administration task, in case there is a strain difference in responding on the active lever during the 20s timeout periods between trials.
aIn our experiments the jitter was set as a random variable uniformly distributed between 0 and 3 ms. bIt should be noticed that this value is a typical routing entry time-to-live value of DSDV protocol or ACTIVE-ROUTE-TIMEOUT value of AODV protocol.
Completion of the reinforcement schedule on the active lever produced the simultaneous activation of a cue light and tone generator followed 1 s later by a 6 s cocaine infusion; immediately after each infusion, a house light was activated signaling a 20 s timeout period.
As described before, active feedback fails when a collision or timeout occurs; however, their impacts are different from each other.
In cases where the number of active subdomains will not lead to a kernel timeout, the chunking is simply omitted.
Two main conditions lead to stalling: alternative paths that underestimate the RTO (retransmission timeout) value, and the SCTP sender not knowing that the path is active when a network error causes only SACK packet losses.
Cocaine (.25 mg/infusion;.1 mL/5 sec) was available under a fixed-ratio 1 (FR1) (continuous reinforcement) schedule of reinforcement in which one active lever press resulted in an infusion and initiated a 20-sec timeout.
