Seismic noise of several sensors. The relative location of the recording points is needed more or less precisely for the different techniques, requiring either manual distance measurements or differential GPS location. The advantages of ambient vibration techniques compared to active techniques commonly used in exploration geophysics or earthquake recordings used in Seismic tomography. Limitations of these methods are linked to the noise wavefield but especially to common assumptions made in seismic: Seismic noise In geology and other related disciplines, seismic noise is a generic name for a relatively persistent vibration of the ground, due to a multitude of causes, that is a
Therapeutic effect strategy or agent. To maximize therapeutic effects (desired) and minimize side effects (undesired) requires recognition and quantification of the treatment in multiple dimensions. In the specific case of targeted pharmaceutical interventions a combination of therapies is often needed to achieve the desired results. Therapeutic effect Therapeutic effect refers to the responses(s) after a treatment of any kind, the results of which are judged to be useful or favorable. This is true whether the result was expected, unexpected, or even an unintended consequence. An adverse effect (including nocebo) is the converse and refers to harmful or undesired responses(s). What constitutes a
