  • Interesting fact: Methylphenidate (Ritalin) is a medication prescribed for individuals (usually children) who have an abnormally high level of activity or attention-deficit hyperactivity disorder (ADHD). According to the National Institute of Mental Health, about 3 to 5 percent of the general population has the disorder, which is characterized by agitated behavior and an inability to focus on tasks. Methylphenidate also is occasionally prescribed for treating narcolepsy. Methylphenidate is a central nervous system (CNS) stimulant. It has effects similar to, but more potent than, caffeine and less potent than amphetamines. It has a notably calming effect on hyperactive children and a "focusing" effect on those with ADHD.

    • n agitator [It has been supposed that in this sense the proper spelling of the word is adjutator, meaning not one who agitates, but one who assists. But Dr. J. A. H. Murray says: “Careful investigation satisfies me that Agitator was the actual title, and Adjutator originally only a bad spelling of soldiers familiar with Adjutants and the Adjutors of 1642.”]

In science:

Thermal agitation makes the polymer explore different configurations.

But since these agitations only cause continuous changes, the polymer will remain in a single topological class.

Modal noise prediction in fibre-spectroscopy I: Visibility and the coherent model
An agitation frequency of 80 Hz (fig. 4(a)) gives the best agitation results (low SNR in the respective exposures), and the modal pattern achieves a low contrast.
Modal noise prediction in fibre-spectroscopy I: Visibility and the coherent model
Operating the agitation device at higher frequencies does not visibly improve the contrast, nor could a significant change in SNR be observed.
Modal noise prediction in fibre-spectroscopy I: Visibility and the coherent model
From laser exposures it appears that additional manual agitation would improve the result, but again no difference for the SNR-value could be measured.
Modal noise prediction in fibre-spectroscopy I: Visibility and the coherent model
These are supplemented by a set of exposures recording the fibre in the agitated state.
Modal noise prediction in fibre-spectroscopy I: Visibility and the coherent model
In order to remove any instrumental signature (e.g. beating pattern due to the bandpass-filter), the unagitated fibre exposures are flat-fielded against the exposures of the agitated fibre.
Modal noise prediction in fibre-spectroscopy I: Visibility and the coherent model
After calculating the modal noise for the unagitated fibre exposures, the same procedure was applied to the exposures of the agitated fibre to compare with the theoretical photon noise, which was directly derived from Poisson statistics.
Modal noise prediction in fibre-spectroscopy I: Visibility and the coherent model
With a few exceptions, all agitated fibre modal-noise values match with the theoretical photon noise, while always achieving significantly higher SNR-values than for the unagitated fibre.
