Because Arya Stark 's direwolf, Nymeria, attacks Prince Joffrey Baratheon along the banks of the Trident, Nymeria is ordered to be killed but she cannot be found.
In the context of computer networks, jitter is the variation in latency as measured in the variability over time of the packet latency across a network. A network with constant latency has no variation (or jitter). Packet jitter is expressed as an average of the deviation from the network mean latency. However, for this use, the term is imprecise.
A spike-by-spike analysis of spike-time jitter allows us to determine those stimulus features that contribute most to the transmitted information; brief sound pressure upstrokes that also occur at prominent locations within the grasshopper songs. These upstrokes can elicit spikes with remarkable temporal accuracy.
