Transmission of coherent light through photonic gratings with varying Kerr nonlinearity is modeled within a coupled-mode system derived from the Maxwell equations. The incident light waves are uniformly stable in time-dependent dynamics if the photonic grating has zero net-average Kerr nonlinearity. When the average nonlinearity is weak but nonzero, light waves exhibit oscillatory instabilities...

A paradigm for quantum synchronization is the analog of Stuart--Landau oscillator, which corresponds to a van der Pol oscillator in limit weak (i.e. vanishingly small) nonlinearity. Due this limitation, fails capture interesting nonlinearity-induced phenomena such as relaxation oscillations. To overcome deficiency we propose an alternative model approximates finitely large nonlinearities while ...

Projections of future climate change for given CO2 and other greenhouse gas emission scenarios depend on the response global climate-carbon cycle feedback, which consists carbon-concentration feedback (e.g., physiology effect land carbon sink) carbon-climate radiative sink). Previous studies have assumed no significant interaction between these two feedbacks within Earth system. This study quan...

Silicon physical unclonable functions (PUFs) are security primitives relying on intrinsic randomness of IC manufacturing. Strong PUFs have a very large input-output space which is essential for secure authentication. Several proposed strong PUFs use timing races to produce a rich set of responses. However, these PUFs are vulnerable to machine-learning attacks due to linear separability of the o...

The average strongto weak-motion amplification ratios during the 1989 Loma Prieta and 1987 Whittier Narrows earthquakes in California are estimated by modeling strong ground motions at soil sites in the linear-response assumption and comparing the simulated and observed records. The linear amplification function, used to synthesize ground motions, is the generic transfer function developed for ...

Strain-induced laterally ordered In0.4Ga0.6As on 311 A GaAs template quantum wires have been fabricated and identified with cross-section transmission electron microscopy technique to be of average length 1 m, and on average width and height of 23 and 2 nm, respectively, under InGaAs coverage of six monolayers. The photoluminescence spectrum of a sample demonstrates unusually strong optical non...

Starting from the car suspension system, nonlinear characteristics of a class two-degree-of-freedom oscillators with strong nonlinearity under periodic excitation are discussed by switching theory flow in discontinuous dynamical systems. Based on forces and different motions two masses, phase plane each mass is composed stick domain, nonstick domain (or free domain) separation boundary absolute...
