The whole cell configuration of the patch clamp technique was used to investigate the mechanism underlying rectification of the isoproterenol-activated chloride (Cl-) current in isolated guinea pig ventricular myocytes. When extracellular Cl- was replaced with either bromide (Br-), glutamate (Glut), iodide (I-), isethionate (Iseth), or nitrate (NO3-), the magnitude of the shift in reversal pote...

Transport properties of various semiconducting zig-zag carbon nanotube Y junctions are studied for the investigations of rectification and switching. Our results indicate that such junctions, when symmetric, can support both ballistic rectification and/or the ballistic switching operating modes. Although structural symmetry of the Y junction is found to be a necessary condition for rectificatio...

Ionic transport in charged conical nanopores is known to give rise to ion current rectification. The present study shows that the rectification direction can be inverted when using electrolyte solutions at very low ionic strengths. To elucidate these phenomena, electroneutral conical nanopores containing a perm-selective region at the tip have been investigated and shown to behave like classica...

We introduce an operational definition of the Berry Phase Rectification Tensor as second-order change polarization a material in response to ideal short pulse electric field. Under time-reversal symmetry this tensor depends exclusively on phases Bloch bands and not their energy dispersions, making it intrinsic property each which contains contributions from both inter-band shift currents intra-...

Stereo image is frequently used as preprocessing of stereo vision techniques. Although stereo image rectification is performed using look-up tables which are computed in advance, it takes a long time to do rectification transformation on mobile platforms. Thus stereo image rectification process can be burdensome in stereo vision applications on mobile platforms. This paper presents an approach ...

In this paper we study how learning can be used in several aspects of car detection and tracking. The overall goal is to develop a system that learns its surrounding and subsequently does a good job in detecting and tracking all cars (and later pedestrians and bicycles) in an intersection. Such data can then be analyzed in order to determine how safe an intersection is. The system is designed t...
