Memoryless Dual-Observer-Based Output Feedback Stabilization of Linear Systems With Input and Output Delays.

This article focuses on the dual-observer-based stabilization of linear systems with delays in both the inputs and outputs. By a model reduction approach the system can be converted to an equivalent linear system without delays, for which a dual-observer-based stabilizing controller can be designed. However, such a controller is infinite dimensional or memory-based.

Detecting coexisting oscillatory patterns in delay coupled Lur'e systems.

This work addresses the problem of pattern analysis in networks consisting of delay-coupled identical Lur'e systems. We study a class of nonlinear systems, which, being isolated, are globally asymptotically stable. Assembling such systems into a network via time-delayed coupling may result in the change of network equilibrium stability under parameter variation in the coupling.

Robust partial synchronization of delay-coupled networks.

Networks of coupled systems may exhibit a form of incomplete synchronization called partial synchronization or cluster synchronization, which refers to the situation where only some, but not all, systems exhibit synchronous behavior. Moreover, due to perturbations or uncertainties in the network, exact partial synchronization in the sense that the states of the systems within each cluster become identical, cannot be achieved. Instead, an approximate synchronization may be observed, where the states of the systems within each cluster converge up to some bound, and this bound tends to zero if (the size of) the perturbations tends to zero.

Benefits of short educational programmes in preventing drink-driving recidivism: A ten-year follow-up randomised controlled trial.

Background: One fifth of drivers convicted of drink-driving for the first time will be convicted again for the same offence in subsequent years. Lecture-based educational programmes are believed to reduce recidivism. Little is known about the modalities of enhancing the benefits of such programs.

Trigeminal neuralgia relief with intrathecal ziconotide.

Objective: We report a case of a 59-year-old female with severe TN who experienced satisfactory symptom relief from a single-shot trial of intrathecal ziconotide.

Method: Performed a 1 μg single-shot trial of Prialt.

Results: Report of satisfaction, no side effects, and complete face and back relief briefly but most notably relief from the TN.
