We present a systematic classification of emergent particles in all 528 magnetic layer groups and 394 rod groups, which describe two-dimensional one-dimensional crystals respectively. Our approach is via constructing correspondence between given layer/rod group one the space group, such that irreducible representations can be derived from those corresponding group. Based on these representation...

The highly conserved topological structure of G protein-activated adenylyl cyclases seems unnecessary because the soluble cytoplasmic domains retain regulatory and catalytic properties. Yet, we previously isolated a constitutively active mutant of the Dictyostelium discoideum adenylyl cyclase harboring a single point mutation in the region linking the cytoplasmic and membrane domains (Leu-394)....
