The morphological differences between EdaTa and Edardl-J T2 can be explained by their crown size differences referring to the 'patterning cascade mode of cusp development' [19] in which the signaling centre succession, and consequently the number and position of cusps, is linked to the crown size.
With respect to the Carabelli cusp, there are several studies in which positive associations between cusp presence/expression and crown size have been reported [20], [21], [22], [23], [24].
The polar cusp is a region in which the magnetosheath plasma has direct access to the ionosphere.
The magnetospheric cusp is a region in which the magnetosheath plasma has direct access to the polar ionosphere, and is the first region to directly respond to IP shocks in geospace (Fuselier et al. 2000; Zhou et al. 2009).
More relevant to our study, Jernvall et. al [54] showed experimentally that, while mice and voles have nearly identical genetic control of initial cusp patterning, they exhibit different overall adult cusp positions due largely to the different position in which the second cusp in their lower first molar appears.
One variant of the simple cycloid is the curtate cycloid, for which the curve falls below the line at the cusps, making retrograde loops in which the curve moves in the direction opposite to that of the rolling circle.
When the Clintons tried and failed to push through their health-care reform plan, pharmaceutical companies were on the cusp of a new age in which they would sell powerful pills to the masses.
Erik Weihenmayer, the first blind person to climb Mount Everest, wrote in an essay that Pistorius was "on the cusp of a paradigm shift in which disability becomes ability, disadvantage becomes advantage.
The 1950s represented the cusp of a new era in which drug treatment would end tuberculosis visibility in industrialized countries.
Tribosphenic placental ancestors have an isolated buccal cusp, considered the paracone, and give rise to many lineages in which a second buccal cusp is added distally, called the metacone.
