A non-linear attenuation of time-domain spectra was observed as a function of compaction force, which corresponded to compact density predictions (R2 = 0.948).
Given that produced time represents the rate of the biological stopwatch-like system [1], the attenuation of produced time observed on day 2 in the SD condition might be associated with the stopwatch-like system that runs faster [13].
Apart from the described transient changes, we found no significant attenuation of the time biases over the whole experimental session in either animate or inanimate sessions.
Moreover, there was no significant attenuation of the time biases with repeated presentations of the moving character, contrary to the notion that pairing a timing task with a concurrent well-practiced distractor leads to a systematic reduction of the time bias with repeated presentations [28].
If alteration of subcortical activities might be caused by sleep deprivation, attenuation of short-time perception probably reflects subcortical vulnerability, and the change in PFC activity is possibly a by-product.
Also, the XML inputs for this application code contain structural geometries, source parameters, seismic velocity, density, attenuation values, number of time steps to compute, and number of stations.
Although a comparison between the early study of Jacobsson et al. [ 25] and our study reveals significant methodological differences (e.g., correction for attenuation, the number of time points studied), their effective dose estimates based on measurements with I-MIBG are of the same order of magnitude as those presented here.
Salomon et al employed the MLAA to estimate activity and attenuation from time-of-flight PET data with spatial MR prior information on attenuation.
To illustrate the potential magnitude of such attenuation with time, the "excess" serum level of 2,3,4,7,8-pentaCDF in 1996 was estimated for the index case.
In this study we (i) explore the somatotopic specificity of pain attenuation over time and (ii) investigate the role of the endogenous opioid system in its development.
Strict clinical, laboratory, and imaging monitoring is required during nonoperative management: multidetector CT consistently allows assessment of changes in size and attenuation of haematomas over time [4, 5, 8, 16, 17].
