In the first molar, four crown points (Fig. 5a) representing its cusps and three root points (Fig. 5b) representing its root apices were demarcated.
Because of the asymmetries, the primary signal upregulates the two master regulators at different thresholds, and the bistable region of the bidirectional two-parameter bifurcation diagram is re-oriented so that its cusps are located on different sides of the X-axis.
Subsequently, the ionogram acquired at 10 45 UT revealed a typical Esc layer (identified with red arrows in Fig. 3) with its characteristic "cusp," which matches with the frequency increase in the fbEs to 7.5 MHz (identified with letter C in Fig. 1).
It captures Japan at a crucial time in its history, on the cusp of opening its borders and becoming a world power, and catches Holland as its own colonial prominence is waning.
"We are sort of at the cusp," its chief anthrax expert, Dr. Bradley Perkins, said.
MHD models appear to be quite successful in predicting the location of the cusp, its magnetic configuration and plasma properties.
Although the crossings are not exactly meridional, they reach 80 81 ILAT and permitting detection of the cusp, its subregions and their equatorward and poleward boundaries.
What characterizes this animal as a eutherian, and not another kind of archaic mammal, are the number of molars and premolars in its jaws, the arrangement of cusps on its teeth, and minute characteristics of its arms and wrists, says lead author Zhe-Xi Luo of the Carnegie Museum of Natural History in Pittsburgh, Pennsylvania.
In this weekend's issue, Sam Sifton provides a recipe for a pork chops dish that used to be served at Relish, a now-shuttered diner in North Williamsburg, Brooklyn, and describes it as "a taste of Brooklyn on the cusp of its move into full food mania".
