In many applications, and in systems/synthetic biology, in particular, it is desirable to solve the switching problem, i.e., to compute control policies that force the trajectory of a bistable system from one equilibrium (the initial point) to another equilibrium (the target point). It was recently shown that for monotone bistable systems, this problem admits easy-to-implement open-loop solutio...

In many applications, and in systems/synthetic biology in particular, it is desirable to compute control policies that force the trajectory of a bistable system from one equilibrium (the initial point) to another equilibrium (the target point), or in other words to solve the switching problem. It was recently shown that, for monotone bistable systems, this problem admits easyto-implement open-l...

Stochastic phenotype switching--often considered a bet hedging or risk-reducing strategy--can enhance the probability of survival in fluctuating environments. A recent experiment provided direct evidence for an adaptive origin by showing the de novo evolution of switching in bacterial populations propagated under a selective regime that captured essential features of the host immune response. T...

This study attempted to investigate the impact of teacher’s code-switching on the acquisition of a problematic grammatical structure, namely, object relative clauses, by intermediate EFL learners. Moreover, a secondary objective of the study was to determine the EFL learners’ attitudes and opinions regarding the effectiveness of teacher’s code-switching in their learning of a specific aspect of...

The free viewpoint switching is one of the most important features of multi-view video streaming. The key problem lies in how to achieve the best performance when the camera processing capability and the network bandwidth are limited. In this paper, we propose a novel free viewpoint switching scheme for multi-view video scenario, in which the distributed video coding technique is employed. In t...

We present the first comprehensive study of the large-signal switching characteristics of an AlGaAs/InGaAs modulation-doped field-effect transistor on a picosecond time scale. Electra-optic sampling is used to measure drain voltage response to a steplike gate input with a 2.8 ps rise time, at various dc biases. A large-signal switching time of 6.2 ps is obtained. Features deleterious to high-fr...
