For instance, Barbero and Thompson [43] proposed a fixed-complexity sphere decoder, where the number of candidates to be searched at the i-th level of sphere decoding tree is at most n i, thereby yielding a constant complexity (prod _{i} n_{i}).
Four levels of multi-sphere approximation for an axi-symmetric ellipsoidal particle were employed in DEM simulation to investigate the adequacy of multi-sphere approximation.
One way of approaching domination in the archaeological record is through the synthetic analysis of different modes of imperial-local interaction at overlapping socio-political levels and spheres of culture.
Kitty Preziosi and I connected on LinkedIn, followed up by phone and found our outrageously high energy levels and spheres of interest were a good match for each other.
A focus on government processes themselves is rather less common - indeed, Foresight Programmes that claim to cover the greater part of the economy typically neglect activities like public administration (despite the high levels of employment in such spheres).
Of note, we found a significant lower levels of free carnitine in spheres as compared with SDACs, suggesting the inhibition of AcCs synthesis and finally of FA beta-oxidation.
Immunoblot analysis revealed a significant increase in the levels of pACC in cancer spheres compared to ADH cultures, indicating activation of AMPK pathway in matrix-deprived cancer cells, consistent with recent reports [ 15, 17].
To determine if Notch signaling is active in the sphere culture, the expression levels of HEY1 in monolayer and sphere cultures were compared.
We also examined the effects of conditioned media from fibroblasts with manipulated levels of miR-149 on sphere formation of GC cells.
Our results clearly showed that the lower chamber cells in modified transwell system were easily forming spheres; furthermore, these spheres expressed high levels of stem cell markers (CD133/CD44/CD24/Oct-4/ESA) and exhibited chemoresistance, underwent epithelial-to-mesenchymal transition (EMT), and possessed the properties of self-renewal in vitro and tumorigenicity in vivo.
