Impulse control in a spectrally negative Lévy model with a level-dependent intensity of bankruptcy
We consider an optimal dividend problem with transaction costs where the surplus is modelled by a spectrally negative Lévy process in an Omega model. n this model, the surplus is allowed to spend time below the critical ruin level, but is penalised by a state-dependent intensity of bankruptcy. We show that under the spectrally negative model an optimal strategy is such that the surplus is reduced to a level $c_1$ whenever they are above another level $c_2$, and that such levels are unique unde…

Modeling and Mixed-Integer Nonlinear MPC of Positive-Negative Pressure Pneumatic Systems
Positive-negative pressure regulation is critical to soft robotic actuators, enabling large motion ranges and versatile actuation modes. However, it remains challenging due to complex nonlinearities, oscillations, and direction-dependent, piecewise dynamics introduced by affordable pneumatic valves and the bidirectional architecture. We present a model-based control framework that couples a physics-grounded switched nonlinear plant model (inflation/deflation modes) with a mixed-integer nonlinea…

Enhanced negative capacitance in La-doped Pb(Zr$_{0.4}$Ti$_{0.6}$)O$_3$ ferroelectric capacitor by tuning bias voltage pulse to induce intrinsic domain switching kinetics
We report a remarkable enhancement of specific negative capacitance in multidomain La-doped Pb(Zr$_{0.4}$Ti$_{0.6}$)O$_3$ (PLZT) ferroelectric capacitors when bias voltage pulse profile (amplitude and timescale) induces switching of the ferroelectric domains following intrinsic switching kinetics associated with minimum energy barrier. This is because of emergence of maximum domain wall density during ``switching" of the domains. Domain configuration changes from such an ``optimum" state if hig…

Negative Lyapunov exponent of circle maps forced by expanding circle endomorphisms
We study maps on the torus $\mathbb{T}^2$ that are of the form $F(x,y) = (bx, f_x(y))$, where $b\geq 2$ is an integer. We establish an open class of $C^1$-maps, with $f_x(y)$ that are typically non-monotonic in $x$, for which the Lyapunov exponents on the fibre are negative almost everywhere. For each fixed $f_x(y)$ and a base map $bx$ that is sufficiently expanding, we establish a uniform upper bound for the Lyapunov exponents; moreover, the uniform bound depends on selective characteristics o…
