Sentence examples for fast negative from inspiring English sources

The transient absorption signal of a pure carbon nanotube sample is also shown for comparison in Fig. 4. The signal consists of two contributions: a fast negative transient lasting for a very short period of time and a positive contribution that lasts for the remaining of the measured delay time period.

We find a fast negative change in absorption due to the occupation of states by the photo-generated carriers mainly in the intrinsic hole region near the top of the valence band and a recovery within a few picoseconds associated with redistribution of the photo-generated carriers in nearby energy states.

Time averaged Langmuir probe measurements have shown that electron temperatures, ion and electron densities and ion fluxes to the substrate all increase with increasing pulse frequency, and that a burst of "hot" electrons is associated with the fast negative voltage transient between "reverse" and "on" phases of the target voltage.

The green bacilli were IF positive, acid fast negative (IF+ AR−) whilst the yellow population was IF+ AR+.

Thereby, inhibitory quantal efficacy is coupled to local network activity, providing a fast negative feedback loop for homeostatic plasticity.

The saturated rod responses include a fast negative peak (see Figs. 1A, 2A, C), the nose, which originates from the action of h and probably Kx channels in the rod inner segment [15].

Local activation time was measured as the difference in the times of the fastest negative deflections (dV/dt) seen in the two electrograms recorded with the reference catheter and the mapping catheter.

It has the fastest negative population growth in the world, and that's because hardly anyone is having babies.

One population of bacilli was acid-fast negative.

Another in vitro study showed that altered mycolic acid ratios along with a shortened mycolic acid chain length render M. tuberculosis acid-fast negative [24].

The number of acid-fast negative cells developed in the complemented strain (C-Δ-tgs1) of Δ-tgs1 mutant was comparable to the wild type (Fig. 11A).
