Biometrika, 1988 The paper presents at first an outline of the basic linear algebra of the classical biplot. Let X be an \(n\times p\) matrix containing numerical information on p variables for each of n samples. The graphical representation of X in a biplot is based on the singular value decomposition \(X=UGV'\), where U and V are \(n\times n\) and \(p\times p ...

Solitary wave solutions of hierarchy with non-local nonlinearity
Applied Mathematics Letters, 2020 The hierarchy of nonlinear differential equations with non-local nonlinearity is considered. Solitary wave solutions of the hierarchy are found. The case of solitary waves for twelfth-order nonlinear differential equation is analyzed in detail.

Second order nonlinear frequency generation at the nanoscale in dielectric platforms
Advances in Physics: X, 2022 Nonlinear frequency generation at the nanoscale is a hot research topic which is gaining increasing attention in nanophotonics. The generation of harmonics in subwavelength volumes is historically associated with the enhancement of electric fields in the

Optimizing the Nonlinearity and Dissipation of a SNAIL Parametric Amplifier for Dynamic Range [PDF]
Physical Review Applied, 2018 We present a new quantum-limited Josephson-junction-based 3-wave-mixing parametric amplifier, the SNAIL Parametric Amplifier (SPA), which uses an array of SNAILs (Superconducting Nonlinear Asymmetric Inductive eLements) as the source of tunable ...

Dizhen xuebao, 2019 为了分析总谐波失真度和互调失真度这两个非线性指标的测试方法、输入信号幅值等变化对其测试结果的影响，本文从总谐波失真信号、互调失真信号的产生原理出发，详细地给出了两种指标的测试方法、数据处理方法及相关影响分析，并通过实际应用中不同类型的输入信号进行了总谐波失真度和互调失真度试验。测试结果表明：信号模式和信号幅值对总谐波失真度的影响显著；输入信号幅值对互调失真度的影响较大；输入信号的频率变化对两指标的测试结果无影响。本研究进一步细化了地震数据采集器性能指标的标准化测试方法 ...

Nonlinearity of root trait relationships and the root economics spectrum
Nature Communications, 2019 The root economics spectrum (RES), a common hypothesis postulating a tradeoff between resource acquisition and conservation traits, is being challenged by conflicting relationships between root diameter, tissue density (RTD) and root nitrogen ...

Nonlinearity in a dynamo [PDF]
, 2009 Using a rotating flat layer heated from below as an example, we consider effects which lead to stabilizing an exponentially growing magnetic field in magnetostrophic convection in transition from the kinematic dynamo to the full non-linear dynamo.
