Developed during the late 1920s and early 1930s by Edwin H. Armstrong, an inventor and a major in the U.S. Army Signal Corps during World War I, this new method of modulation offered heretofore unattainable reduction of the effect of ignition and other noises encountered in radios used in vehicles.
The method of modulation analysis and filtering has extensively been studied by many researchers in the field of single channel speech separation; Reference [19] provides a general discussion on this subject.
It may be concluded, therefore, that variation of EDC concentration provides a simple method of modulation of the physical and biological properties of scaffold material.
Thus, the challenge for new biotechnology is to develop a method of modulation rather than modification of the genome which, however, is similar to the agrotransformation effect.
First, mechanical methods of polarization modulation are typically relatively slow, introducing significant 1/ f noise into the measurement.
Extracorporeal methods of immune modulation have shown promise for treatment of sepsis; however, achieving an appropriate response is a major challenge [ 1].
To compare discharge modulation of the 32 neurons during the 2 task conditions, Figure 5 C, D plots response phase and sensitivity (re-stimulus velocity, see Materials and Methods) of discharge modulation of each neuron during head-pursuit against those during passive head rotation on the stationary trunk.
The possibility of using such semiselective methods of immune modulation which do not require long-term administration may be a more natural and easily tolerated means of treating autoimmune disease than current techniques in which immune modulators are given on a continuous basis.
We sought to determine an optimal method for modulation of gene expression in intact adult human islets that would be transient and would be minimally disruptive in terms of islet architecture, function and viability.
We aimed to evaluate a new method of temperature modulation with an esophageal heat transfer device in a pediatric swine model, hypothesizing that clinically significant modulation in temperature (both increases and decreases of more than 1°C) would be possible.
