The precise direct and indirect mechanisms of viral contribution to exacerbations must still be elucidated.
But there is no denying that the steering is precise, direct and linear, or that one quickly becomes accustomed to its feel.
A specially designed experimental setup allows precise direct following of time evolution of the chemical composition profiles along the diffusion path.
In a fitting cap to the World Year of Physics 2005, MIT physicists and colleagues report the most precise direct test yet of Einstein's most famous equation, E=mc2.
The experiment provided the most precise direct verification to date of the inverse square law and showed, to a confidence limit of 95%, that the inverse square law was obeyed down to a distance of 55 micrometres (0.002 in).
Here we use ultrastable oscillator frequency sources to perform a modern Michelson Morley experiment and make the most precise direct terrestrial test to date of Lorentz symmetry for the photon, constraining Lorentz violating orientation-dependent relative frequency changes Δν/ν to 9.2±10.7 × 10−19 (95% confidence interval).
But co-author Michael N. Nitabach, Ph.D., J.D., associate professor of cellular and molecular physiology and of genetics, says that the method used by these scientists, which tracks calcium levels in neurons, provides only an indirect measure of electrical activity, while the tools developed at Yale provide a precise, direct measure.
Considering long mission duration (at least 1 year is planned) this would allow for the first time a precise direct determination of the low-degree tidal Love numbers of the Moon and, in combination with high precision SEST, would provide an experimental basis to study relativistic effects such as the periselenium advance in the Earth Moon system.
Hume's philosophical work is outstanding: insightful, precise, direct.
