St. Petersburg Polytechnical University Journal: Physics and MathematicsIn order to reveal the effect of nonlinear (cubic) parametric excitation (NPE) on the interaction of forced, parametric, and self-oscillation with a limited-power energy source, a widely used computed model of a self-oscillating system receiving energy ...

Numerical simulation of unsteady viscous flows [PDF]
Most unsteady viscous flows may be grouped into two categories, i.e., forced and self-sustained oscillations. Examples of forced oscillations occur in turbomachinery and in internal combustion engines while self-sustained oscillations prevail in vortex ...

Advanced Functional Materials, EarlyView.Ferroelectric memcapacitors enable non‐volatile, voltage‐programmable capacitance tuning for adaptive electronics. A TiN/HfZrO/TiN device stack demonstrates more than eight stable capacitance states within a 24 pF memory window in compact 60 ×$\times$ 60 μm2$\umu{\rm m}^{2}$ devices at low operating voltages.

Advanced Functional Materials, EarlyView.We present ultrathin flexible transparent electrodes through iCVD‐enabled molecular control of 10 nm gold films on poly(dimethylaminomethylstyrene). In vivo validation demonstrated photoelectric artifact reduction vs. opaque electrodes and preservation of natural neural dynamics.

Forced oscillations for delay motion equations on manifolds
Electronic Journal of Differential Equations, 2007 We prove an existence result for $T$-periodic solutions of a $T$-periodic second order delay differential equation on a boundaryless compact manifold with nonzero Euler-Poincare characteristic.

Longitudinal oscillations of the sugar beet root crop body at vibrational digging up from soil
Research in Agricultural Engineering, 2005 The longitudinal vibrations theory of a continuous elastic body with one fixed extremity is designed. The Ostrogradskii-Hamilton principle of a stationary operation is applied.

Adaptive Hydrogels With Spatiotemporal Stiffening Using pH‐Modulating Enzymes
Advanced Functional Materials, EarlyView.The chemomechanical coupling in an adaptive hydrogel is studied to further the development of adaptive hydrogels. This coupling is achieved by embedding a pH‐modulating enzyme in a pH‐responsive hydrogel. The enzymatic reaction can be triggered locally, which generates a pH‐decreasing wave throughout the system, increasing the crosslinking density and ...

Sensitivity analysis of stochastically forced quasiperiodic self-oscillations
Electronic Journal of Differential Equations, 2016 We study a problem of stochastically forced quasi-periodic self-oscillations of nonlinear dynamic systems, which are modelled by an invariant torus in the phase space.
