This would have improved the validity of our findings, since such cancers diagnosed soon after the baseline personality assessment might have distorted responses because of to subclinical symptoms caused by as-yet diagnosed cancers.
Unless extreme caution is used, it appears possible that these algorithms can accidently distort response features not caused by diffusion across a gap, including lag and overshoot, and thereby confound the quantification of DA's kinetic parameters.
We have evidence that cerebrovascular regulation is impaired in CCHS, since global blood oxygen level dependent signals, reflecting a combination of cerebral blood flow and oxygenation, are grossly distorted in response to CO2 and O2 challenges [45].
Major nonlinear phenomena that can be extracted from transient and/or steady-state dynamic responses include different nonlinearities, softening and hardening effects, intrawave amplitude- and phase-modulation, distorted harmonic responses under a single-frequency harmonic excitation, interwave amplitude- and phase-modulation, and multiple-mode vibrations caused by internal/external resonances.
This exposure misclassification bias could have distorted exposure-response trends in comparisons involving more than two levels.
Generally, the chief bias in these studies was exposure misclassification that most likely underestimated the risk, as well as distorted exposure-response relationships.
Earlier radio telescopes used a symmetric tripod or quadrapod structure to hold the feed or secondary reflector, but such an arrangement blocks some of the incoming radiation, and the reflection of signals from the support legs back into the receiver distorts the response.
When designing wind turbine blades or aeroplane wings, engineers traditionally had to use two different models, one to calculate how the structure would displace the air and another to calculate how the structure would distort in response to the airflow.
