An N -dimensional digital binary image (I) is a function I : Z → {0, 1}. I is B3N−1,W3N−1 connected if and only if its black pixels and white pixels are each (3 − 1)-connected. I is only B3N−1 connected if and only if its black pixels are (3 − 1)-connected. For a 3-D binary image, the respective connectivity models are B26,W26 and B26. A pair of (3 N − 1)-neighboring opposite-valued pixels is c...

Serogroup A meningococci are a leading cause of bacterial meningitis in children and young adults worldwide. However, the genetic basis of serogroup A strains' virulence and their epidemiological properties remain poorly understood. Therefore, we sequenced the complete genome of the transformable Neisseria meningitidis serogroup A strain WUE2594.
