The threshold intensity decreases by about 10 dB when the duration of a tone burst is increased from 20 to 200 ms.
2.
The intensity of the pressure signal was tested without noise and then set at a near sub-threshold intensity that would evoke 10 action potentials over a 60-second stimulation time.
3.
The intensity at which a stimulus ( e . g ., heat, pressure ) begins to evoke pain is thus called by a separate term, " threshold intensity ".
4.
The threshold intensity ( blue line ) required to switch the molecules to the dark state is only a fraction of the maximum intensity applied, so only molecules very close to the position of minimum intensity can be in the bright state.
5.
" r is the lateral resolution, " is the FWHM of the diffraction limited PSF, " I " max is the peak intensity of the STED laser, and I _ { s } is the threshold intensity needed in order to achieve saturated emission depletion.
6.
But it may be that favorable changes in heart function and levels of blood fats require a " threshold intensity " of exercise eqnditure translates into more than 200 calories daily, equivalent to about 24 minutes of moderate-intensity cycling or a 30-minute walk at 4 to 5 miles an hour.
