Nonlinear response of Q-boosting metasurfaces beyond the time-bandwidth limit
Nanophotonics, 2022 Resonant nanostructures, such as photonic metasurfaces, have created an unprecedented case for enhanced light–matter interactions through local field engineering. However, the presence of resonances fundamentally limits the bandwidth of such interactions.

Bipartite Consensus on Coopetition Networks With Time-Varying Delays
IEEE Access, 2018 In this paper, the bipartite consensus problem is investigated for multiagent systems with second-order dynamics and antagonistic interactions. We consider bipartite consensus under two kinds of protocols.

The extinction probability in systems randomly varying in time
Nuclear Engineering and Technology, 2017 The extinction probability of a branching process (a neutron chain in a multiplying medium) is calculated for a system randomly varying in time. The evolution of the first two moments of such a process was calculated previously by the authors in a system

An invariance principle for time-varying systems
2012 IEEE 51st IEEE Conference on Decision and Control (CDC), 2012 In this paper we propose an invariance principle for time-varying dynamical systems. We first present a novel proof of the Krasovskii-Lasalle invariance principle for forward time using invariance properties of regions of attraction, rather than the invariance property of the limit set.

Quadratic Performance Analysis of Switched Affine Time–Varying Systems
International Journal of Applied Mathematics and Computer Science, 2018 We analyze quadratic performance for switched systems which are composed of a finite set of affine time-varying subsystems, where both subsystem matrices and affine vectors are switched, and no single subsystem has desired quadratic performance.

Metzler asymptotic stability of initial time linear time-varying real-order systems
Franklin Open, 2023 Determining the asymptotics of many time-varying systems associated with real orders remains a challenging issue in qualitative asymptotic theory. This paper introduces a new concept of Metzler asymptotic stability to linear time-varying real-order ...

Positivity and stability of fractional descriptor time–varying discrete–time linear systems
International Journal of Applied Mathematics and Computer Science, 2016 The Weierstrass–Kronecker theorem on the decomposition of the regular pencil is extended to fractional descriptor time-varying discrete-time linear systems. A method for computing solutions of fractional systems is proposed.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background PIK3CA‐related overgrowth spectrum (PROS) includes several rare overgrowth disorders resulting from somatic gain‐of‐function mutations in PIK3CA. Despite treatment advances, including the recent approval of alpelisib for PROS in the United States, literature detailing the patient experience with PROS is limited.

Time-varying Lense–Thirring system [PDF]
Classical and Quantum Gravity, 2008 We consider bound geodesic orbits of test masses in the exterior gravitational field of a rotating astronomical source whose proper angular momentum varies linearly with time. The linear perturbation approach of Lense and Thirring is herein extended to the nonstationary case.
