Weight changes in cocaine users reflect fundamental perturbations in fat regulation.
Careful categorization of known mutants displaying cotyledon defects reveals a group, which obviously reflects more fundamental perturbations such as cell differentiation in altered meristem program [ 9, 10], control of meristem cell fate and lateral organ development in dornröschen [ 11] and division plane orientation in fass [ 12].
This study aims at normatizating acoustic measures including fundamental frequency, perturbation and noise using the Acoustic Voice Analysis Program.
The first contribution of this study is to formally prove that the time-asymptotic moments matching method applied to two-equation models is equivalent to a fundamental deterministic perturbation decomposition proposed in Quintard et al. (2001) [1] for mass transport and in Moyne et al. (2000) [2] for heat transfer.
Mean fundamental frequency, amplitude perturbation measures, and noise-to-harmonics ratio were not significantly different between groups.
Typical features are fundamental frequency (F0), perturbation measures such as jitter (changes in pitch with time) and shimmer (changes in amplitude with time), and harmonics-to-noise ratio (HNR) [ 2– 8].
It seems that the two most fundamental sources of experimental perturbation are the degradation of the polymer chains during the purification step and the composition fluctuations during feeding of the reaction system.
In parkour, the roll landing strategy is explored during the early stages of learning, as the ability to land safely and then continue to move in a controlled manner, after experiencing a perturbation, is fundamental for an athlete's performance, safety and wellbeing [24].
Clinically, acoustic measures such as the fundamental frequency and amplitude perturbation coefficients (jitter and shimmer, resp).
The measures cepstral peak prominence (CPP) and smoothed CPP (CPPS) do not require exact determination of the cycles of fundamental frequency like established perturbation-based measures.
