The two have spiked together in the last few years, but the D.C. economy achieved separation from national trends in the Reagan and Clinton years and lift-off under George W. Bush, a long three decade period when government's share of the national income was relatively flat.
In contrast, PA63 and LF spiked together resulted in significant formation of complex in both serum (1.8 ± 0.16 ng/mL) and plasma (2.0 ± 0.074 ng/mL), with plasma LTx measured higher than serum.
The cause of this spike (together with high levels of heptane, xylene and organic alcohols) was attributed to the use of the petroleum based adhesive Styccobond F60 which was applied to the flooring of the hallway during the sampling campaign.
Fig. 18 Network burst distribution in number of spikes, together with geometric (red) and power law (blue) fit; Δt, the mean inter-spike interval, is the time bin used to calculate the distribution, and (beta=-1.62) is the slope exponent of the fit.

Backpropagation spikes, together with coincident synaptic depolarization, evoke a massive Ca2+ influx [10], which in turn, triggers the intracellular signalling pathways of LTP.
Moreover, our finding (i.e., the axon as a gainer of somatic spikes) together with the theory of local circuit current [6] present a comprehensive view for the axons to amplify somatic sequential spikes to constant level (Fig. 8) and to propagate them securely toward axonal terminals.
The correlation index measures the degree that two units spike together within some small time window (typically 50 ms).
For recordings of ac4 sensilla, in which action potential amplitude differences did not allow reliably attribution to the activity of a single neuron, we counted all spikes together.
Use a small amount of wood glue to secure the spikes together, forming an "X" shape.
By looping and twisting the wire, bind the staking spikes together.
