To scan the whole area, the microscopic image field was moved transversely (along x-axis) back and forth, shifting along y-axis with each scan (supporting information, Figure S4a).
Two adjacent TibC protomers projecting oppositely contact each other in a back-to-back manner around a dyad axis; six back-to-back dimers are further linked together in a hand-in-hand fashion around a sixfold axis to form the garland-like ring.
The y-axis (back-to-front) shows different developmental stages from 1-cell (zygote) to 64-cell (blastocyst).
(i) The y-axis (back-front) that shows time of development, as early and late developmental stages are located in backward forward of the landscape, respectively.
Organizing space around an axis harks back to Persian paradise garden traditions, Mr. Smith said, and the resulting triangular patterns were considered sacred geometry.
As first observed in 1891 by Seth Carlo Chandler Jr., an insurance actuary turned astronomer, the Earth's axis sways back and forth about 20 feet every 14 months.
If the mechanical axis drifts back out of the physiologic range — usually evident within 12 months of plate removal — guided growth may be repeated.
In traditional bike designs, with a steering axis tilted back from the vertical, positive trail tends to steer the front wheel into the direction of a lean, independent of forward speed.
The 1st Regiment of the Brandenburg Division, reinforced by a pioneer company from the 373rd (Croatian) Infantry Division and the Chetnik Dinara Division, attacked along the Knin Bosansko Grahovo axis, pushed back the local Grahovo Peulje Partisan Detachment and by the end of the day had reached positions some 5 km beyond Strmica.
Two years ago, Jon Olsson pioneered double flips — off-axis double back flips — on large jumps.
