Nonlinear Mixed-Effects Modeling of MNREAD Data
Investigative Opthalmology & Visual Science, 2008 It is often difficult to estimate parameters from individual clinical data because of noisy or incomplete measurements. Nonlinear mixed-effects (NLME) modeling provides a statistical framework for analyzing population parameters and the associated variations, even when individual data sets are incomplete. The authors demonstrate the application of NLME

New Oscillation Criteria for Second-Order Forced Quasilinear Functional Differential Equations
Abstract and Applied Analysis, 2013 We establish some new interval oscillation criteria for a general class of second-order forced quasilinear functional differential equations with ϕ-Laplacian operator and mixed nonlinearities.

On a Weak Solution of the Mixed Nonlinear Schrödinger Equations
Journal of Mathematical Analysis and Applications, 1994 We study the following Cauchy problem for the mixed nonlinear Schrödinger equation (mixed NSE): \[ U_ t=i\alpha U_{xx}+\beta U^ 2 \overline{U}_ x+\gamma| U|^ 2 U_ x+ig(| U|^ 2)U,\qquad U(x,0)=U_ 0(x), \] where \(\alpha\), \(\beta\), \(\gamma\) are real constants with \(\alpha\neq 0\), \(\overline U\) denotes the complex conjugate of \(U\), the real ...

On the Complexity of Nonlinear Mixed-Integer Optimization [PDF]
, 2011 This is a survey on the computational complexity of nonlinear mixed-integer optimization. It highlights a selection of important topics, ranging from incomputability results that arise from number theory and logic, to recently obtained fully polynomial time approximation schemes in fixed dimension, and to strongly polynomial-time algorithms for special

A mixed formulation of nonlinear-elastic problems
Computers & Structures, 1992 Summary: The objective is to present a systematic development of mixed finite element models within the context of nonlinear material models. The framework for this effort is the Hu-Washizu functional, due to the relative ease with which is incorporates nonlinear material laws.

Comparison Criteria for Nonlinear Functional Dynamic Equations of Higher Order
Discrete Dynamics in Nature and Society, 2016 We will consider the higher order functional dynamic equations with mixed nonlinearities of the form xnt+∑j=0Npjtϕγjxφjt=0, on an above-unbounded time scale T, where n≥2, xi(t)≔ri(t)ϕαixi-1Δ(t), i=1,…,n-1, with x0=x, ϕβ(u)≔uβsgnu, and α[i,j]≔αi⋯αj.
