Copper already has spiked way past the price projections of the Street and of industry players.
Metals, oil and agricultural products like corn, wheat and soybeans, particularly corn, spiked the past few months.
More biophysical realism can be obtained by allowing for post-spike currents generated by past spikes [22].
Similarly, the post-spike current arises from past spikes through a response kernel (k_{h}(t)) by (H t)=int_{-infty}^{t}k_{h} t-s mathbb{I} t-s mathbb{
Even when Elmander rolled captain Aaron Hughes to spike a shot past Maik Taylor, Sanchez said he had faith in his players' "resilience".
The withered brown flower spike was well past its best but its botanical charisma more than compensated for a lack of beauty.
As Buffy turns immortal, she shines beatifically, and we finally understand the foreshadowing significance in Spike's puzzling past fondness for the words "effulgent" and "glowing".
Previous research had extended back roughly 1,500 years, and suggested that the rapid temperature spike of the past century, believed to be a consequence of human activity, exceeded any warming episode during those years.
In other words, one can know the value of the conductances g k j at time t only if the past spike times of the network are known.
Therefore, gIF models constitute rather complex dynamical systems: the vector field (r.h.s) of the differential Equation (16) depends on an auxiliary "variable", which is the past spike sequence ω − ∞ [ t ] and to define properly the evolution of V k from time t to later times one needs to know the spikes arising before t.
