These hit different firms in different ways: an oil-price spike, for example, is good for oil producers, bad for airlines, and only slightly negative for retailers.
In order to understand the role of calcium spiking, for example, Oldroyd immersed himself in the huge body of literature on calcium signals, most of which resulted from work done in animal systems.
In addition, within Izhikevich's framework several mechanisms exist for increasing the sensitivity of a neuron to a single spike, for example, using a mixed mode neuron described by the following parameters (a = 0.02, b = 0.2, c = −55, d = 4, I = 2), a single EPSP of 10 mV is sufficient to cause a post-synaptic spike [53].
Variable speed wind turbine can help to smooth out short-term spikes output, for example, running the wind turbine faster during gusts-storing energy in the same way as a flywheel.
He commonly wrote for unconventional instruments (using the accordion, Cuban drums, cimbalom, or kamāncheh [a Persian spike fiddle], for example, with Western orchestral instruments), and he sometimes used sampled and amplified sounds.
While the extra classes found with this method may not play a role in neuronal bursting [21], they could be relevant for other types of bursting system, for which oscillations are not necessarily spike-like, for example epileptic seizures.
Additionally, STDP has been shown to be sensitive to a number of factors beyond spike timing, for example active dendritic properties and the location of the synapse on the dendrite — see Kampa et al. (2007) for a review.
"Athletes need to consider the number and length of the spikes in relation, for example, to body weight, prevalent conditions (wet surfaces require more assistance in traction) and type of event," he says.
She said they were useful when traffic spiked; this September, for example, the financial crisis spurred lots of page views.
The volume of tweets shows a major spike of activity, for example, in the days after Clinton stumbled in New York on Sept. 11 while battling pneumonia, a moment that sharpened concerns about her health.
