Pronounced AQP1 immunohistochemical expression was detected on the surface of central vein and liver sinusoid of ND rats, presumably reacting with the endothelial cells lining the central vein and liver sinusoid.
Four probing signal types were used: i) single rectangular pulse; ii) quasichirp (rectangular version of linear frequency modulation signal); iii) set of rectangular CW tonebursts with variable fill-in frequency and iv) CW sinusoid of variable frequency.
So in order to not get the signals mixed up, the light is pulsed or modulated by a continuous-wave source, typically a sinusoid or square wave.
In the case of a change in time t of the acting on the materials of the wire (cable) of the HHIT pulsed current [i.sub.p](t) according to the law of a damped sinusoid of the form
The variation in the ramp-to-ramp phase is almost linear in slow time (Inter-ramps: the DFT now occurs along each ramp in the distances profile obtained previously [5]), so that a sinusoid of constant frequency is produced.

If the basis function can be interpreted as a windowed sinusoid, then both methods are essentially the same [53].
A good representation is a sinusoid with upper and lower peaks in July and January (Figure 4).
What this means is a Fast Fourier Transform can decompose A-scans to yield a separate acoustic image for each sinusoid. There may be a dozen or more such images.
CoreWire Technology builds on Continuous Sinusoid Technology (CST), a method of stent manufacturing first introduced with Medtronic's Resolute Integrity DES, which molds one single strand of wire into a sinusoidal wave enabling a continuous range of motion.
Quadrature sinusoid oscillators are widely used in orthogonal signal mixers, in PLLs and SSB modulators; some such oscillators based on various active devices, for example, voltage operational amplifier-VOA [9], CFOA [10,11], CDBA [12,13], CDTA [14], DDCC [15], CCCCTA [16], OTA [17], and DVCCTA [18,19], are reported.
