The nature of the induced motion is dominated by the relative position of the external force direction and the centroid of the object. For example, the object will merely translate along the direction of the external force in case the force passes through the objective centroid. If not, the ...

26and achieve gate-tunable negative refraction27. These features can be successfully used to realize broadband sound absorbers26or sound barriers28. Recent breakthroughs have also been made in the context of programmable mechanical metamaterials29,30. Virtualized metamaterials allow us to freely ...

aThus they can be used for correcting refraction errors of the eye for example by making soft and flexible contact lenses. 因而他们可以为改正眼睛的折射错误使用例如通过做软和灵活的隐形眼镜。[translate] acooling tower above 冷却塔上面[translate] ...
of a magnet bar without any physical contact. falling raindrops on earth is also an example of a non-contact force. the charging of the hair and attraction of paper bits towards it. two magnets placed close to each other are also a non-contact force example. the freefall of a ball ...
As an example of a system utilizing these fibers, consider a block of ten 50 km optical fiber spans comprised of NZ-DSF with a dispersion of −3.4 ps/nm/km. These concatenated fibers have an accumulated dispersion of −1700 ps/nm that can be perfectly balanced (or compensated) by two...
which are improved greatly comparing to those obtained using the conventional two-color recording.The evolution of the grating intensity versus time as well as the influence of oxidation/reduction treatment on the photorefraction is simulated numerically.The results show that the numerical simulations ...
Inspection of residuals revealed no obvious systematic deviations between model predictions and joystick position. Example-course data for single trials is shown for the same individual participants in Supplementary Fig. 1. Modeling stage 1: joystick vs. contrast calibration The first modeling stage ...
The flourishing of topological photonics in the last decade was achieved mainly due to developments in linear topological photonic structures. However, when nonlinearity is introduced, many intriguing questions arise. For example, are there universal fingerprints of the underlying topology when modes are...
