Torben Larsen received his M.Sc. degree in electrical engineering from Aalborg University, Denmark, in 1988. In 1995 he founded the RF Integrated Systems and Circuits group, which today counts more ...

We report on two novel routes to generating a train of attosecond pulses from a broad discrete spectrum in the near-infrared–visible–ultraviolet range. One extends an integer-temporal-Talbot (ITT) ...

It is shown that an ergodic measure preserving transformation with quasi-discrete spectrum is conjugate to: (a) the skew-product of an ergodic measure preserving transformation with discrete spectrum ...

In this paper, we introduce the B-discrete spectrum of an unbounded closed operator and we prove that a closed operator has a purely B-discrete spectrum if and only if it has a meromorphic resolvent.

HANNOVER, Germany, June 15, 2018 /PRNewswire/ -- At CEBIT 2018, Huawei released its 4.5G-based, 5G-oriented eLTE Discrete Spectrum Aggregation (eLTE-DSA) solution. This solution provides energy ...
