Biometrika, 1988 The classical biplot (Gabriel, 1971) of a multivariate sample X of n units by p variables is generalized for any Euclidean imbeddable metric dij. Sample-units are represented in the usual way by points in an ordination, most conveniently using principal coordinates. Variables are represented by a set of p concurrent nonlinear trajectories whose lengths

Progressive Myoclonus Epilepsy: Distinctive MRI Changes in Cerebellar and Motor Networks
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Progressive myoclonus epilepsy (PME) is a rare generalized epilepsy syndrome with a well‐characterized genetic basis. The brain networks that are affected to give rise to the distinctive symptoms of PME are less well understood. Methods Eleven individuals with PME with a confirmed genetic diagnosis and 22 controls were studied.

Demonstration of Fully Nonlinear Spectrum Modulated System in the Highly Nonlinear Optical Transmission Regime [PDF]
arXiv, 2016 We report a 3 dB increase in the nonlinear threshold of a 64*0.5Gbaud 16-QAM continuous-nonlinear-spectrum modulated signal by nonlinear multiplexing with QPSK modulated multi-solitons, showing the first ever fully nonlinear-spectrum modulated system in the highly nonlinear regime.

Annual Review of Economics, 2016 I examine the use of nonlinear pricing as a method of price discrimination, both with monopoly and oligopoly supply. Topics covered include an analysis of when it is profitable to offer quantity discounts and bundle discounts, connections between second- and third-degree price discrimination, the use of market demand functions to calculate nonlinear ...

Cerebral Amyloid Angiopathy Is Associated With Higher R2 Relaxation Rate: An MRI and Pathology Study
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Cerebral amyloid angiopathy (CAA) involves β‐amyloid deposition in the walls of cortical and leptomeningeal small vessels. Transverse relaxation rate (R2) is a major source of contrast in MRI. This study tested the hypothesis that CAA is associated with R2, extracted the spatial pattern of CAA‐related R2 abnormalities, and evaluated ...

Open Mathematics, 2016 The paper deals with the existence of positive ω-periodic solutions for a class of nonlinear delay differential equations. For example, such equations represent the model for the survival of red blood cells in an animal. The sufficient conditions for the

Nonlinear Schroedinger Dynamics and Nonlinear Observables [PDF]
arXiv, 1995 It is is explained why physical consistency requires substituting linear observables by nonlinear ones for quantum systems with nonlinear time evolution of pure states. The exact meaning and the concrete physical interpretation are described in full detail for a special case of the nonlinear Doebner-Goldin equation.

IEEE Transactions on Automatic Control, 1985 In this note we make some remarks about the general observer problem for nonlinear systems. We show how the existence of a partial observer without stability requirements is locally equivalent to the existence of a conditioned invariant distribution. We argue that by considering not only identity observers we can put the stability issue in a broader ...
