Captions, where they exist, vary widely in tone.
The regulations that do exist vary by state and aren't very rigorous.
During the optimization process, there exist objectives whose values vary within small ranges, which means they are wasting the computing resource of MOEAs.
It is found that there exist the stability switches when delay varies, and the Hopf bifurcation occurs when the delay passes through a sequence of critical values.
What information does exist varies widely.
You are there, exist there.
However, even among the well-conserved structures of 16S rRNA, there exist hypervariable regions which vary in their secondary structure from taxon to taxon.
Studying the geographical variation of neonatal mortality is of particular interest because access to antenatal or reproductive care vary and there exist regional differences in availability of services [10], hence newborn health may vary.
As there are varied levels of control and targets to be regulated, there exists a wide repertoire of RNA-binding motifs.
Between 10 and 13 Earth radii toward the Sun, there exists the magnetosheath, a region of magnetic turbulence in which both the magnitude and direction of Earth's magnetic field vary erratically.
