Many analog-mixed-signal (AMS) circuits and control systems are naturally modeled as hybrid systems: state machines with a continuous dynamics given by ordinary differential equations (ODEs) at each state, and transitions whose guard conditions depend on the values of the continuous variables. The continuous dynamics for these models are often weakly non-linear. In particular, the intended beha...
UNLABELLED Nanobodies are single-domain antigen-binding fragments derived from heavy-chain antibodies that are devoid of light chains and occur naturally in Camelidae. We have shown before that their small size and high affinity and specificity for their target antigen make Nanobodies ideal probes for in vivo tumor imaging. In the present study, we have evaluated the use of Nanobodies as a gene...
Special-purpose stream-processing systems are becoming increasingly popular due to the demands of multimedia applications, digital signal processing, and cryptography. In stream-processing systems, algorithms are typically implemented as a series of hardware stages. Each hardware stage receives the data stream from the previous stage and, after processing, sends the new data stream to the next ...
We show that using recurrent networks with finite time constants is not contradictory to arbitrary fast signal transmission in a closed loop with appropriate feedbacks. This surprising result is due to the occurrence of infinitely amplifying subloops, which we formally describe by differential inclusions. The theory then shows that the transmission speed depends crucially on the gain of the tra...
The power spectrum of the optical intensity at the output of a single-mode-fiber recirculating delay line driven by a multimode semiconductor laser is shown to exhibit a spectral structure with notches at zero frequency as well as at other multiples of 1/(loop delay). A theoretical model based on laser phase noise is suggested to explain the experimental data.
