Effects of cocaine on briefly signaled versus completely signaled delays to reinforcement.

Signaled Queueing

Burstiness in queues where customers arrive independently leads to rush periods when wait times are long. We propose a simple signaling scheme to decrease wait times by distributing customer arrivals more uniformly. Agents receive one of several signals with suggestions on what time to join the queue. We quantify the efficiency gains, both analytically and empirically, with respect to a number ...

Signaled Receiver Processing

Effects of signaled and unsignaled alternative reinforcement on persistence and relapse in children and pigeons.

Three experiments explored the impact of different reinforcer rates for alternative behavior (DRA) on the suppression and post-DRA relapse of target behavior, and the persistence of alternative behavior. All experiments arranged baseline, intervention with extinction of target behavior concurrently with DRA, and post-treatment tests of resurgence or reinstatement, in two- or three-component mul...

Low-voltage differentially-signaled modulators.

For exascale computing applications, viable optical solutions will need to operate using low voltage signaling and with low power consumption. In this work, the first differentially signaled silicon resonator is demonstrated which can provide a 5dB extinction ratio using 3fJ/bit and 500mV signal amplitude at 10Gbps. Modulation with asymmetric voltage amplitudes as low as 150mV with 3dB extincti...

Within-subject testing of the signaled-reinforcement effect on operant responding as measured by response rate and resistance to change.

Response rates under random-interval schedules are lower when a brief (500 ms) signal accompanies reinforcement than when there is no signal. The present study examined this signaled-reinforcement effect and its relation to resistance to change. In Experiment 1, rats responded on a multiple random-interval 60-s random-interval 60-s schedule, with signaled reinforcement in only one component. Re...
