We systematically examine the possibility of generating the three basic non-context-free constructions in natural and artificial languages — replication, multiple agreements and crossed agreements — by means of various types of parallel communicating grammar systems. Answering a problem left open in [2], we prove that also the last construction specified above can be covered by centralized (context-free)...
We fabricate thin epitaxial crystal silicon solar cells on display glass and fused silica substrates overcoated with a silicon seed layer. To confirm the quality of hot‐wire chemical vapor deposition epitaxy, we grow a 2‐µm‐thick absorber on a (100) monocrystalline Si layer transfer seed on display glass and achieve 6.5% efficiency with an open circuit voltage (VOC) of 586 mV without light‐trapping...
