GaAs-based two-dimensional electron gases (2DEGs) show a wealth of remarkable electronic states(1-3), and serve as the basis for fast transistors, research on electrons in nanostructures(4,5) and p

In our research on the fabrication of Nb/Al-oxide/Nb mixer elements, we have discovered an unexpected effect which is attributable to the geometry of the mixer, We have found that the electrical qu

The exchange interaction between amorphous Tb-Fe and crystalline Ni-Fe produces a unidirectional anisotropy in the magnetically soft Ni-Fe layer.

An unextendible product basis (UPB) for a multipartite quantum system is an incomplete orthogonal product basis whose complementary subspace contains no product state.

A novel and comprehensive model for Semiconductor Optical Amplifiers (SOAs) to be used in high bit rate (10-160 Gb/s) optical communication systems is presented.

The FP6 UNIC (UNIversal satellite home Connection) Project aims at developing an end-to-end scientific test bed for the creation, optimization and validation of new broadband interactive TV-centric

To case equalization in a multicarrier system, a cyclic prefix (CP) is typically inserted between successive symbols.

Usually the speech and the silence models are trained together depending upon the type of recognition task.

Unified analytical expressions are derived for calculating the equivalent input noise current and transimpedance of optical receiver front ends with arbitrary input matching network topologies, To

In non-coherent wideband fading channels where energy rather than spectrum is the limiting resource, peaky and non-peaky signaling schemes have long been considered species apart, as the first appr
