The crevasses are often invisible, covered only by thin bridges of snow.
A sand castle is made of a network of sand grains glued together by very thin bridges of water.
The robustness and speed of the algorithm is demonstrated through a series of examples involving thin bridges, coatings, narrow necks, corners, cusps, and random mixtures.
Below the third ventricle, the rostral-most pole of the SCN formed a thin bridge-like structure containing a densely packed group of AVP-ir neurons, which we will refer to as the rostrum (Figure 4C D, see also [6]).
This appears to occur in the latter because most of the TGN membranes are used for the packaging of secretory granules, and the tubules only form the thin bridges between the granule precursors.
Larger aggregates comprising tubules (Fig. 2e,g, indicated as T) and vesicle clusters (Fig. 2g, indicated as V) connected by thin bridges (Fig. 2g, white arrows) appeared to be enclosed in large membranes.
This drawbridge was designed to have two parts — a wide, heavy bridge that would be raised or lowered when the family was in residence, and a thinner bridge, easier to lift, designed for the use of servants at other times.
From the Navier equations we derive that the lowest resonant frequencies are associated with localised bending modes solutions of a fourth-order differential equation in thin-bridges, which are responsible for the appearance of a low frequency stop band.
