    structures with small dimensions of state spaces. These
    constructions have contributed to the theory of orthomodular
    lattices. More general quantum structures (orthomodular posets,
    orthoalgebras, and effect algebras) admit sometimes
    simplifications, but there are problems where no progress has been
    achieved.  },
