A p-i-n junction diode based on the selectively doped single-walled carbon nanotube (SWCNT) had been investigated, in which two opposite ends of individual SWCNT channel were doped into the p- and n-type SWCNT respectively while the middle segment of SWCNT was kept as the intrinsic. The symmetric and asymmetric contacts were used to fabricate the p-i-n junction diodes respectively and studied t...

Asymmetric beaming in a piecewise-linear propagation channel is demonstrated for single photonic-crystal prism at Gaussian-beam illumination. The used hybrid refraction–diffraction mechanism exploits oblique incidence, the first-negative-order deflection longer interface, and asymmetry coupling exit interfaces does not need blocking of transmission by dispersion backward illumination case. Floq...

Rectification of interacting Brownian particles is investigated in a two-dimensional asymmetric channel the presence an external periodic driving force. The force can break thermodynamic equilibrium and induces rectification (or finite average velocity). spatial variation shape leads to entropic barriers, which indeed control particles. We find that by simply tunning frequency, amplitude, chann...

In this paper, we devise an efficient joint source-channel coding scheme for robust image transmission over noisy channels. We firstly present a novel interleaver, named unequal row column cyclic cross interleaver, which could improve the error correction capability of turbo codes effectively. Secondly, we devise two types of asymmetric turbo codes which consist of the parallel concatenated tur...

We study competition and coordination in a supply chain in which a single supplier both operates a direct channel and sells its product through multiple differentiated retailers competing in quantities. We study analytically the supply chain with symmetric retailers and find that the supplier generally prefers to have as many retailers as possible in the market, even if the retailers’ equilibri...

In the present study we investigate computationally the deformation of an elastic capsule in a rectangular microfluidic channel and compare it with that of a droplet. In contrast to the bullet or parachute shape in a square or cylindrical channel where the capsule extends along the flow direction, in a rectangular channel the capsule extends mainly along the less-confined lateral direction of t...
