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.

UNLABELLED The physiological state of natural competence for transformation allows certain bacteria to take up free DNA from the environment and to recombine such newly acquired DNA into their chromosomes. However, even though conserved components that are required to undergo natural transformation have been identified in several naturally competent bacteria, our knowledge of the underlying mec...

| The step-invariant or ZOH-transformation of discrete-time transfer function models to continuous time is discussed. It is shown that negative real poles which are commonly considered as not transformable, can be transformed to poles on the aliasing margin. Thus a generalized equivalent can be determined, whose ZOH-transform is the original system. Numerical algorithms are also discussed, and ...

The Veillonella atypica strain OK5 was isolated from a human saliva sample and was the first strain shown to be genetically transformable in the Veillonella genus. Genetic studies using this strain have helped us gain much insight into the ecology of human oral biofilms. Here, we report the complete genome sequence of V. atypica OK5.

A single-crystal to single-crystal transformable coordination polymer compound was hydrothermally synthesized. The structural rearrangement is induced by selecting a ligand that contains both strong and weaker coordinating groups. Both hydrated and dehydrated structures were determined by single crystal X-ray analysis.
