The dynamic holographic method based on light-induced refractive index change during the interaction of beams in a material occupies a special place because it allows to potentially implement almost all currently known functions of manipulation of light [11,12].
These soft tissue fillers provide correction by two basic mechanisms: (1) the filler material occupies a void space, or (2) the filler material stimulates processes that produce volume.
These assumptions are related to the modeling of reaction diffusion processes in composite materials occupying a bounded domain Ω, which at some points behave as perfect insulators.
Since the magnitude of optical gain is the practically most limiting factor, the modulation space for PT-symmetric materials occupies a relatively small region in the index modulation diagram, while plasmonic and metallo-dielectric metamaterials occupy the widest region in the vs. modulation space.
Foams are modelled as two-phase composites consisting of a solid material and voids; the elasto-plastic and damage response of the parent material is deduced from its measured mechanical responses in tension and compression, while the material occupying the voids is assigned a plastically compressible constitutive response, to mimic the effects of pore collapse and subsequent self-contact.
This ring is a faint sheet of material occupying the space between the Le Verrier ring at about 53,200 km and the Arago ring at 57,200 km.
The presence of arterial thrombosis is observed in B-mode as echogenic material occupying arterial lumen.
Let us recall (see for instance [31]) that as (varepsilon rightarrow0), for (i=1,2), chi_{Omega_{ivarepsilon}}rightharpoonuptheta_{i}:= frac{vert Y_{i}vert}{|Y|} quadmbox{weakly in } L^{2}(Omega) (2.2) (theta_{i}) being the proportion of the material occupying (Omega _{ivarepsilon}).
A'. x-z projection of a z -stack of the image shown in A revealing minor vein architecture in transverse section and the presence of highly-localized and very substantial deposition of wall ingrowth material occupying nearly half the cell volume (asterisk).
