Additionally, evidence is presented that across-subject hypothesis tests may be more sensitive when conducted using perfusion imaging, despite the better within-subject signal to noise obtained in some cases with BOLD.
Finally, these results underscore the fundamental importance of subjecting hypotheses to carefully conducted clinical trials.
On the subject of hypothesis, he simply tells us that Timon regarded it as a question of primary importance whether anything should be assumed by hypothesis.
A common misperception is that evolutionary biology is an inherently historical science and thus cannot be subject to hypothesis testing.
Since genotyping is not described in either study, the nature of the mutation in these patients, and hence the course of the disease, is subject to hypothesis.
To subject our hypothesis to a more rigorous test, we allowed replication forks to travel greater distances from the origins before HU treatment and then measured the sites of chromosome breakage in samples recovering from HU.
The set of epistemic values that we impart to scientists and historians include the value of intellectual discipline and a willingness to subject their hypotheses to the test of uncomfortable facts.
The purpose is, therefore, to test, using in-vivo feline model and healthy human subjects, the hypothesis that RLI due to prolonged exposure to repetitive lumbar flexion extension is triggered by an acute inflammation in the viscoelastic tissues and is characterized by lingering residual creep, pronounced changes in neuromuscular control and transient changes in lumbar stability.
Repeated measures multivariate analysis of variance RM-MANOVAA, equivalentoto "profile analysis") was used to test the between-subjects null hypothesis of no difference between nutrient-enriched and control treatments across sampling times for a suite of response variables.
These might include media interest and public awareness in the subject and hypotheses under investigation, and health behaviors that may be related both to participation and risk factors being studied.
In the structured approach, the human-identified features are subjected to hypothesis testing not by creating new prospective experiments, but by extensively searching data derived from prior experiments [ 38].
