Based on single-cell recordings of 156 photoreceptors, the presence of three components in UV cones of hatchlings and terrestrial adults ruled out a developmental transition. There was no evidence for multiple opsin types within rods or S cones, but immunohistochemistry and partial bleaching in ...
We report here, to the best of our knowledge, the first simultaneous emission of three continuous-wave solar laser beams by end-side-pumping three 3.0 mm diameter, 25 mm length Nd:YAG single-crystal rods within a single conical pump cavity. An aspheric fused silica lens was used to couple...
1. (Textiles) a rod or stick that has a notch in the top, used to draw out natural fibres for spinning into thread, and a long narrow body around which the thread is wound when spun 2. (Textiles) one of the thin rods or pins bearing bobbins upon which spun thread is wound in a...
In examples like the one above, rods, lenses, cones, and a punched cone which have been found together in bullae can be compared to the units 1, 10, 60, and 10 · 60 of the well-documented proto-cuneiform/proto-Elamite system S of sexagesimal counting numbers. Note the alternation of...
We study force-extension curves of a single semiflexible chain consisting of several rigid rods connected by flexible spacers. The atomic force microscopy and laser optical or magnetic tweezers apparatus stretching these rod-coil macromolecules are discussed. In addition, the stretching by external isot...
The limits of hamiltonian structures in three-dimensional elasticity, shells, and rods This paper uses Hamiltonian structures to study the problem of the limit of three-dimensional (3D) elastic models to shell and rod models. In the case of s... Z Ge,HP Kruse,JE Marsden - 《Journal of No...
Such systems can be natural, such as cell colonies5,6,7, epithelial tissues8,9, bacterial suspensions10,11,12, and microtubule and motor protein mixtures13, or artificial, such as vibrated granular rods14,15. A key property of active matter is the emergence of spontaneous, collective motion ...
roadsterswere the old-fashioned style of bicycle popular in the countryside. They usually had635 mm(28 x 1 1/2) wheels withWestwoodrims, longcranksand longwheelbases, and very shallow(68 degrees or less.) Roadsters used "" brakes operated by rods, instead of cables. The typical roadster...
Here, differential strain acting on films provides a means to engineer nanomembranes of virtually any material31. Chemical synthesis techniques are generally more suited to deliver 3D nanostructures. Using heterogeneous nucleation methods, assemblies of rods, dumbbells or branched networks can be produced...
The device (1) has three point connecting rods (5) including two lower links (6) and an upper link (7), where a device connecting axle (8) is connected wit... LAUMANN BERNHARD 被引量: 0发表: 2009年 Matching three-point functions of BMN operators at weak and strong coupling Zayakin...
