We introduce quantum point contact microscopy (QPCM) as a novel method for surface characterization, where the conductance through a quantum point contact formed by a metal atom between the tip of a scanning tunneling microscope and the surface is mapped a ...
This article describes a new approach to the macroscopic first order modeling and simulation of traffic flow in complex urban road intersections. The framework is theoretically sound, operational, and comprises a large body of models presented so far in th ...
Experimental evidence from the JET tokamak is presented supporting the predictions of a recent theory (Graves et al 2009 Phys. Rev. Lett. 102 065005) on sawtooth instability control by toroidally propagating ion cyclotron resonance waves. Novel experimenta ...
Fiber slow light systems are at a turning point moving from a laboratory research to real applications. The possibility to shape the spectral resonance in Brillouin slow light leads to optimized configurations and innovative solutions. ...
The ubiquitous role of optical fibers in modern photonic systems has stimulated research to realize slow and fast light devices directly in this close-to-perfect transmission line. Recent progress in developing optically-controlled delays in optical fibers ...
Fiber slow light systems are at a turning point moving from a laboratory research to real applications. The possibility to shape the spectral resonance in Brillouin slow light leads to innovative solutions and makes possible the realization of optimized co ...
he aim of this paper is to discuss the integration of uncertainity analysis in an thermo-economic optimization method for process system design. Most of time energy systems are designed under constant parameters, whereas some of them are uncertain in real ...
The relationships between instantaneous space-variables and (easily measurable) local time-variables in largely homogeneous and stationary traffic flow, as typically encountered in uninterrupted traffic conditions, are briefly reviewed. An elaborate analys ...
We report on the dynamics of confined zero-dimensional polaritons. We excite resonantly discrete polariton states optically with a tailored picosecond laser pulse and observe their emission time resolved in the two-dimensional k space or real space. We are ...
In the experience of neutron scattering, the structure factor is a value that can be almost directly measured (through the differential inelastic neutron scattering cross section). Thus it can be interesting to have a calculation which could give a theoret ...
