Recent Progress on Nonlinear Schrödinger Systems with Quadratic Interactions
The Scientific World Journal, 2014 The study of nonlinear Schrödinger systems with quadratic interactions has attracted much attention in the recent years. In this paper, we summarize time decay estimates of small solutions to the systems under the mass resonance condition in 2 ...

Inducing Ferromagnetism by Structural Engineering in a Strongly Spin‐Orbit Coupled Oxide
Advanced Functional Materials, EarlyView.ABSTRACT Magnetic materials with strong spin‐orbit coupling (SOC) are essential for the advancement of spin‐orbitronic devices, as they enable efficient spin‐charge conversion, complex magnetic structures, spin‐valley physics, topological phases and other exotic phenomena.

Linear Systems of Real Quadratic Forms [PDF]
Proceedings of the American Mathematical Society, 1964 1. It is natural to consider invariantive properties of k-dimensional linear systems of real quadratic forms over Rn (or quadratic forms over Rn with values in RkI 2< k5 In(n + 1)), because of the occurrence of such objects at least in the following contexts: in the second fundamental form of classical differential geometry for n-dimensional manifolds ...

Algorithmic Design of Disordered Networks With Arbitrary Coordination: Application to Biophotonics
Advanced Functional Materials, EarlyView.Predictive Design of Disordered Networks: Disordered network‐like morphologies are abundant in nature, from cytoskeletal networks to bone structures and chalcogenide glasses. These structures are naturally hard to characterize. A new algorithmic tool extends the established Wooten–Weaire–Winer (WWW) algorithm to valencies above 4.

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.

Polynomial First Integrals of Quadratic Systems
Rocky Mountain Journal of Mathematics, 2001 The paper contains a classification and the topological phase portraits of all quadratic systems having minimal polynomial first integrals of degree at most 4. The authors prove the existence of minimal polynomial first integrals of any degree for quadratic systems and show that such systems having more than three invariant straight lines have no ...

Ultrasmall Platinum Nanoparticles for Radiation‐Enhanced Cancer Therapy
Advanced Functional Materials, EarlyView.This work proposes a nanomedicine‐based strategy to enhance X‐ray radiotherapy for cancer treatment. Ultrasmall Pt‐NPs exhibit catalase‐like activity that may contribute to modulation of the tumor microenvironment and amplify interactions between radiation and biological matter, leading to increased DNA damage.

Advanced Functional Materials, EarlyView.Efficient two‐photon resonant Raman scattering (TRRS) is observed in the layered perovskite (PEA)2PbI4, with the biexciton level acting as an intermediate state. TRRS undergoes two‐photon frequency shift upon input frequency tuning, persists up to 90 K, and shows clear threshold behavior and polarization selection rules.
