Sinusoidal domain structure

Hepatocytes make up 60-70% of the total number of liver cells. They have a well-organized intracellular structure with huge numbers of cell organelles to maintain the high metabolic profile. At the apical side or canalicular membrane the cell is specialized for the secretion of bile components. There are several ATP-dependent transport carriers located on this side of the membrane, which transport bile salts, lipids and xenobiotics into the canaliculus. On the sinusoidal side, the cells specialize in uptake and secretion of a wide variety of components. To increase the surface of the membrane for this exchange with the bloodstream, the sinusoidal domain of the membrane is equipped with irregular microvilli. The microvilli are embedded into the fluid and matrix components of the space of Disse and are in close contact with the sinusoidal blood because of the discontinuous and fenestrated SECs. To facilitate its metabolic functions numerous membrane transport mechanisms and receptors are situated in the membrane. 

The elemental motile unit of an OHC strikingly resembles the flexoelectric domain structure whose calculated period 7rifn(ei ) also depends linearly on the inverse electric field (Fig. 6.9). Such a repetitive arc and pillar nano-architecture, containing sharp points at the confluence of any two adjacent arcs, is inherently polar and enhances the flexoelectric mechanism (e.g., a sinusoidal-shaped membrane will not enhance flexoelectricity while one of the half-waves is reduced the opposite one will be extended and vice versa). This arc motif is repeated a few thousand times along the... 

Finally, the global error of the enhanced PMLs is explored in the frequency domain for a 3-DFDTD2.4ur x 1.8ur x 2.Our lattice in the presence of a cubic 0.5ur x 0.5ur x 0.5ur lossy scatterer (sr = 2.5). The structure is excited by a ramped sinusoidal excitation Ez n = [1 — e fr/30)2] sin(27r/ z2 /) with the exponential term reducing any form of transients, while the reference domain is 4.0ur x 2.5ur x 3.0ur. Figure 4.3(b) proves that the errors induced by the higher order absorbers are very low for a broad frequency range. 

Fig. 2. Schematic description of the spin structures in the heavy rare earth metals. The initial high-T ordering, in all except the ferromagnet Gd, is to an incommensurate periodic spin order with propagation direction along the c-axis. CAM (c-axis modulation) is a structure in which the c-axis components of the moment are sinusoidally modulated which evolves into the APD (quasi anti-phase domain) in Er in which a gradual squaring-up of the c-axis moment occurs with additional order appearing in the basal plane. The temperatures of the transitions are from magnetization and neutron diffraction data. (After Legvold 1980.)...

Sinusoidal undulations of the optical axis, thin cholesteric layers between columnar domains, and nested-arc textures are all strong indications of a helical structure (Figures 11.18 and 11.19). The nested-arc texture shows the structure of the tilt grain boundary phase particularly well.
