We applied a simplified hierarchy of controls to express a gradient of upstream (materials correspond with source of the hazard) versus midstream (process corresponds with path between source and worker) versus downstream (human interface corresponds with the level of the worker as the receiver of exposure) preventive efforts.
FSH-receptors are expressed mainly in the granulosa while LH-receptors are expressed in a gradient with highest expression in the theca.
The PLT genes are expressed in a gradient with maximal expression in the stem cell niche promoting stem cell identity and maintenance.
This idea appears to hold true in the case of GBM, recent findings suggest that EphA receptors are expressed in a gradient with high expression present on the more aggressive GSC mesenchymal phenotype.
As a primary auditory field, AAF expresses a tonotopic gradient (Figs. 4A, S3A, S3B).
AG-1 is expressed in a gradient increasing from sepals to gynoecium while AG-2 is evenly expressed in all floral parts studied except in petals.
C-class MADS-box genes (AG-1 and AG-2) also show an expanded pattern of expression when compared with the expected expression pattern based on the canonical ABC model (Fig. 3): AG-1 seems to be expressed in a gradient, increasing from sepals (low) to gynoecium (high), while AG-2 is evenly expressed in all floral parts studied with the exception of the petals, where no expression was observed.
Interestingly, double in situ hybridization against wnt-5 and pdx-1 revealed that wnt-5 is expressed as a gradient of RNA from the posterior limit of pdx-1 expression to the tail-bud at the 10-somite stage when pdx-1 is first detected (Fig. 3A).
In the posterior abdomen Abd-B is expressed in a gradient from the posterior compartment of A4 through A7 with strongest expression in posterior A6 and A7 (Fig. 1D) (Kopp and Duncan, 2002; Wang et al., 2011).
Bathymetric relief on carbonate platforms was very gentle; the full spectrum of available communities was likely often expressed over a gradient hundreds of kilometres long.
The output couples the phylogenetic information from the RAxML tree and the contribution of the different branches/lineages to the mutual information (i.e. the information shared between each lineage and the grouping at which a given observation belongs expressed as a gradient of colours, where yellow is the null contribution and dark red the maximum).
