It is shown that the experimental evidence supports the theory that endurance limits at very high cycle fatigue are related to thresholds for crack propagation of incipient cracks from stress-concentration sites.
Further research on animal models is warranted; however, presently, animal models cannot provide quantitative data related to thresholds for either human sensitization or elicitation.
Each age group (eg. 30 49 years old, 50 69, 70 89) separated by 2 decades was assigned pass-fail criterion for TCCT as previous data suggests age related change in threshold for tritan colour.
One of the items suggested for inclusion, the item relating to the threshold for the index test could be covered as part of item 8 (description of index test details).
This might be related to a reduced threshold for triggering CSD in patients with epilepsy in comparison to patients without epilepsy.
The behavior in the spiking transition is considered in connection with the slow- (or pseudo-slow) manifold in Type I (or II), and related to the firing threshold for each type.
Both transient and SSR responses are closely related to the behavioural threshold for detection of the sounds – that is, they appear at roughly the same sound level as that required for a behavioural response [38] [40].
