As a result of QDs properties (big absorption cross-section, long life time, and photo-stability), in vivo imaging constructed by QD agents is very sensitive and blithe but, auto-fluorescence emitted from substrate (noise) are a caution for this procedure and can be an important limitation factor.
But when it's viewed flat under the microscope, those squiggly sheets of membrane extend in cross section, like long, sinewy arms.
Significant change of wire cross section after long exposition was determined by 3D X-ray computer tomography (XCT).
The experimental results demonstrate that the estimates of the aerodynamic derivatives are not sensitive to the motion considered; these results indicate that the principle of superposition is fully applicable for the cross section as long as the motions are within the range considered.
The structure was possible because of Torroja's exceptional conceptual design, which used prestressing in a new way to counterbalance the biaxial bending and torsion problems caused by using deep beams with an open asymmetric cross section in long-span structures.
Petioles reddish to crimson, flat front, rounded back (D-shaped in cross section), 3.5 8 (−10) cm long, 0.5 0.7 cm thick, minutely appressed tomentose to glabrous, narrowly winged on both sides, wings 1 2.5 mm wide.
Hair has microscopic differences (e.g., cuticular, medullar and cross section), which have long been used as forensic markers for identifying human ethnicity and classifying mammalian species [ 20– 23].
Their large bodies were heart-shaped in cross section, like elephants, with long (sometimes extremely long) necks and tails.
In "Cross Sections," the longest and most fascinating work on the disc, Lisa R. Coons painstakingly dissects the instrument, rendering muscular arpeggios, livid feedback, ominous rumbles and radiant drones.
The spokes are 2 × 2 μm in cross section and 155 μm long.
All specimens were characterized by an I-shaped cross section, were 7000 mm long, 630 mm high.
