Understanding the mechanisms of monogenic and monoallelic transcription of the large repertoire of olfactory receptor genes represents a challenging task. A picture is now emerging in which odorant receptor choice and stabilization involve an escape from silencing followed by the activation of an unconventional feedback loop.

The paper addresses the stabilization of periodic orbits in a wedge billiard with actuated edges. It is shown how the rich dynamical properties of the open-loop dynamics, e.g. ergodicity properties and KAM curves, can be exploited to design robust stabilizing feedbacks with large basins of attraction.

A wide range of options is available to surgeons for fixation of the proximal interphalangeal joint when arthrodesis is undertaken for repair of the hammertoe deformity. In this technical report, we describe the use of an intraosseous loop of stainless-steel wire for permanent stabilization of the interface between the proximal and middle phalanges during fusion of the interphalangeal joint.

This paper deals with the stabilization problem for a class of uncertain stochastic systems with Markovian jumps via the static output feedback control, where the uncertain parameters are norm bounded. A static output feedback controller that makes the closed-loop systems asymptotically mean-square stable is designed, which is obtained by solving some linear matrix inequalities.

In this paper, we study the problem of asymptotic stabilization by closed loop feedback for a scalar conservation law with a convex flux and in the context of entropy solutions. Besides the boundary data, we use an additional control which is a source term acting uniformly in space.

In this paper, we propose to regulate the output of an autocatalytic bioprocess by means of a recirculation loop. We show that controlling the recirculation flow rate allows the stabilization of a particular output under a constant or even an unknown input flow. Furthermore, we obtain a convergence in finite time with a smooth feedback law Copyright c ©2005 IFAC.

The semiglobal stabilization of null-controllable linear systems with delayed inputs which are bounded is achieved and the robustness of the closed loop scheme with respect to uncertainty in the parameters, in the delay and input bounded disturbances is proved. A delayed oscillator is stabilized with a bounded control law. Copyright c °2002 IFAC

The global stabilization of a class of feedforward systems having an exponentially unstable Jacobian linearization is achieved by a high gain feedback saturated at a low level. The control law forces the derivatives of the state variables to small values along the closed loop trajectories. This “slow control” design is illustrated with a benchmark example and its limitations are emphasized.

The question of transient stability control is revisited, various types of controls are identified, and a general approach to closed-loop emergency control is proposed. The focus is on feasibility aspects, general salient features and illustration of stabilization capabilities of an emergency control scheme relying on generation shedding.

In this paper we consider the problem of stabilizing continuous-time linear systems containing input nonlinearities and time delays. Specifically, a fixed-order (i.e., fulland reduced-order) dynamic output feedback control technique is proposed and sufficient conditions involving a closed-loop modified Riccati equation is presented for stabilization of systems with sector bounded input nonlinea...
