The three-dimensional reticulation on the right side of the HVS-I torso can be explained by the known parallel occurrence of a transition and a transversion at position 16147 in two samples (C16147T: hg U5b1; C16147A: hg N1a1).
Moreover, tuning the (Ga/III) ratio is possible up to a certain extent beyond which the parallel occurrence of hydrogen evolution reaction (HER) takes place and has negative impact on the film quality such as formation of pinholes and dendritic morphology [70].
While parallel expression of calcium-dependent and calcium-independent NOS isoforms within a certain cell type is common in animal species, the parallel occurrence of two versions of calcium-independent NOS has not been reported, at least to our knowledge.
The first pattern was dubbed variable methylation: In BRMS-1, KiSS-1 and TIMP3, volatility of methylation was high with parallel occurrence of methylated, heterogeneously methylated and unmethylated CpGs at a single methylation site.
Enzymes do not however prevent the parallel occurrence of non-enzymatic reactions.
Historically, catalytic action was regarded as one of the essential characteristics of acids, and the parallel occurrence of catalytic action and electrical conductivity was one of the compelling pieces of evidence in establishing the theory of electrolytic dissociation as the basis of acid base behaviour at the end of the 19th century.
The parallel occurrence of HER hinders the electrodeposition process hence resulting in films with poor morphology and pin holes.
Further increase in deposition potential usually may lead to formation of gallium oxides and hydroxide due to the parallel occurrence of HER [81].
Electrodeposition at high cathodic potential conditions affects the In and Ga plating efficiency due to the parallel occurrence of hydrogen evolution, which is considered to be the origin for film inhomogeneity and pin holes formation.
Parallel occurrence of resistant bacteria in humans and animals is observed in ecological studies.
Many case studies show parallel occurrence of MRSA ST398 in both animals and humans [8], [10], [13] [15].
