"There is not conclusive evidence on which to reject" the model, the report says, adding that "it may never be possible to prove or disprove the validity of the linear nonthreshold assumption".
They argued over when, if ever, there would be physical experiments to prove or disprove the validity of string theory, an attempt to unify the general theory of relativity and quantum mechanics by positing the existence of "strings" that vibrate in a 10-dimensional universe.
More precisely, we focus on functions belonging to some weighted L2 space whose fractional Laplacian belongs to another weighted L2 space: we prove and disprove the validity of the integration-by-parts formula depending on the behaviour of the weight ρ(x) at infinity.
However, statistical considerations failed to disprove the validity of the test and there was no attempt to measure the actual rearrangement process.
Good documentaries almost always have a point - a good documentary may ask a question about the way our society operates, attempt to prove or disprove the validity of a certain point of view, or cast light on an event or phenomenon unknown to the general public in hopes of spurring action.Even documentaries about events that happened far in the past can draw connections to the world today.
According to Berkes (1999), periodic crises evolving around resources use are not disproving the validity of traditional ecological knowledge but might rather lead to its revitalization.
On the other hand, the three-state kinetic model disproves the validity of the experimental procedure aiming at estimating the gating charge of peptide ion channels from the initial stage of the time derivative of ON and OFF ionic currents, commonly justified by an unproved analogy with gating currents of potassium ion channels.
Since disproving the validity of Alcubierre-type warp drives, interstellar propulsion physics is currently non-existent.
