Noise thresholds

The qnery file mnst also be written in the CellMontage format. The noise threshold mnst be in the range of [0,1]. The minimnm modnle parameter sets the minimum size of gene modules to output. The result dir parameter indicates the directory to write the results of final gene modules.

Donoho lohnstone 1994 Donoho lohnstone 1995) developed several wavelet based shrinkage methods to find a smooth estimate of d from the noisy data s. These methods introduce diverse ways to find the optimal choice of the threshold depending on set of criteria. And because smaller coefficients are usually contributed from data noises, thresholding out these coefficients has an effect of removing data noises. 

The simplest way to increase penetration of short pulses is to increase the acoustic power of the ultrasound beam, because signal from deeper tissue regions can be recorded over the noise threshold. However, concerns about potential and undesirable side effects, in particular related to acoustic cavitation, set limits on the possibility of overcoming the frequency-dependent attenuation by increasing peak acoustic amplitudes of the waves probing the tissue. Moreover, low amplitudes are mandatory... 

In all three cases, both the magnitude of the periodic part of the response. signal and its phase shift with respect to the stimulating signal are measured, and this results in a complex quantity (temperature, heat flow rate, and heat capacity, respectively). As heat transport always requires time, the frequency of temperature modulation is normally limited to a maximum of 0.2 Hz to allow the heat to flow through the sample properly. For the 3(0 method, however, frequencies of several kilohertz are possible because the heat source and the temperature probe are identical in this case. At the lower end, the frequency range is only limited by the noise threshold (sensitivity) of the sensors in question. As a rule only two decades are available. Consequently, only time-dependent pr[Pg.838]
