Quadratic harmonic morphisms and O-systems [PDF]
Annales de l'Institut Fourier, 1997 We introduce O-systems (Definition 3.1) of orthogonal transformations of ℝ m , and establish ℝ correspondences both between equivalence classes of Clifford systems and those of O-systems, and between O-systems and orthogonal multiplications of the form μ:ℝ n ×ℝ m →ℝ m , which allow us to solve the existence problems both for O-systems and for umbilical

Advanced Functional Materials, EarlyView.ABSTRACT Breathable membranes that reject chemical warfare agents (CWAs) are required for next‐generation protective apparel. A dual‐function graphene oxide (GO)‐polyamine architecture is introduced that addresses the long‐standing tradeoff between vapor transmission and CWA selectivity.

Regularity of Linear Systems of Differential Equations on the Axes and Pencils of Quadratic Forms
Communications in Advanced Mathematical Sciences, 2019 It is considered linear systems of differential equations and investigated questions of regularity of these systems. To explore the regularity it is comfortable to use quadratic form whose derivative with respect to the adjoint system is positive ...

Triplet‐Triplet Annihilation Enhances Photochemical Curing Contrast for Vat‐Based 3D Printing
Advanced Functional Materials, EarlyView.Triplet–triplet annihilation photopolymerization (TTAP) resins enhance curing contrast for digital light processing (DLP) 3D printing compared to conventional Type I and II photopolymerizations at matched optical densities. By exploiting a superlinear initiation response, TTAP preserves fine details, allowing reliable fabrication of complex structures ...

Advanced Functional Materials, EarlyView.Reprogrammable multi‐material smart textiles knitted from liquid crystal elastomer fibers undergo 2D and 3D deformation under thermal and photo stimuli. Circularly knitted tubular structures reversibly contract in radial and axial directions, enabling autonomous climbing, liquid release, and micro pumping.

QUADRATIC AND CUBIC NON-LINEARITIES IN A QUASI-LINEAR PARAMETRICALLY-EXCITED SYSTEM
Vietnam Journal of Mechanics, 1993 A quasi-linear oscillating system always contains weak factors (negative and positive frictions, exciting forces in resonances, non-linarites of restoring forces) usually characterized by a small parameters €.

Quadratic Jordan Triple Systems
Journal of Mathematics Research, 2019 In this work, We show that every Jordan triple system can be viewed as a T∗extension of another one or an ideal of co-dimension one of a Jordan triple system whose represent the T∗extension of another Jordan triple system. Moreover, several result involving the structure of quadratic Jordan triple systems are given.
