Symmetry Breaking Metamaterial Sleeve Actuators

Advanced Intelligent Systems
Inflatable soft actuators hold promise for applications that require large and complex deformations. Although they adapt readily to their environment and are inherently safe, they still require a large amount of tethers which limit their applicability ...

Constructing Boolean Functions Using Blended Representations

IEEE Access, 2019
In this paper, we study blended representations of Boolean functions, and construct the following two classes of Boolean functions. Two bounds on the $r$ -order nonlinearity were given by Carlet in the IEEE Transactions on Information Theory, vol.

Nonlinear Rayleigh Quotients and Nonlinear Spectral Theory [PDF]

Symmetry, 2019
We give a new and simplified definition of spectrumfor a nonlinear operator F acting in a real Banach space X, and study some of its features in terms of (qualitative and) quantitative properties of F such as the measure of noncompactness, α ( F ) , of F. Then, using as a main tool the Ekeland Variational Principle, we focus our attention on the

Use of a Molecular Signature Response Classifier to Inform Treatment Selection Improves Clinical Disease Activity Among Patients with Rheumatoid Arthritis Initiating a Biologic or Targeted Synthetic Disease‐Modifying Antirheumatic Drug

Arthritis Care &Research, EarlyView.
Objective We assessed the effectiveness of PrismRA to improve clinical outcomes among patients with rheumatoid arthritis (RA) initiating treatment with a biologic or targeted synthetic disease‐modifying antirheumatic drug (b/tsDMARD). Methods PrismRA incorporated 19 gene expression features and four clinical features to assess a patient's likelihood of

Asymptotically linear and superlinear elliptic equations with gradient terms

Electronic Journal of Differential Equations, 2020
In this article we establish the existence of solutions for elliptic problem involving a gradient term. To handle the so-called non-variational problem, we use a variational methods. We assume that the nonlinear term satisfies an asymptotically linear

Design of an Ultrahigh Birefringence Photonic Crystal Fiber with Large Nonlinearity Using All Circular Air Holes for a Fiber-Optic Transmission System

Photonics, 2018
This paper proposes a hexagonal photonic crystal fiber (H-PCF) structure with all circular air holes in order to simultaneously achieve ultrahigh birefringence and high nonlinearity.

Frailty Predicts Incident Osteoporotic Fractures in Veterans with Rheumatoid Arthritis

Arthritis Care &Research, Accepted Article.
Background/Objective Rheumatoid arthritis (RA) is associated with an increased risk of frailty and osteoporosis, but the relationship between frailty and incident osteoporotic fractures in RA is underexplored. Methods Data were from the Veterans Affairs Rheumatoid Arthritis (VARA) Registry.

A Q‐Learning Algorithm to Solve the Two‐Player Zero‐Sum Game Problem for Nonlinear Systems

International Journal of Adaptive Control and Signal Processing, Volume 39, Issue 3, Page 566-581, March 2025.
A Q‐learning algorithm to solve the two‐player zero‐sum game problem for nonlinear systems. ABSTRACT This paper deals with the two‐player zero‐sum game problem, which is a bounded L2$$ {L}_2 $$‐gain robust control problem. Finding an analytical solution to the complex Hamilton‐Jacobi‐Issacs (HJI) equation is a challenging task.

Nonlinear Absorptions

Journal of Functional Analysis, 1993
Let \(A\) be an \(m\)-completely accretive operator in \(L^ 1(\Omega)\), where \((\Omega,{\mathcal B},\mu)\) is a \(\sigma\)-finite measure space. Let \(j: \Omega\times\mathbb{R}\to [0,\infty]\) be measurable in \(x\in\Omega\), convex and lower semicontinuous in \(r\in\mathbb{R}\), with \(j(x,0)=0\).

Adaptive Observer for Coupled Wave PDE and Infinite ODE With Sampled Data and Unknown Input: Application to Brain Hemodynamics Estimation

International Journal of Adaptive Control and Signal Processing, EarlyView.
This article proposes a convergent adaptive observer for a damped wave PDE and an infinite‐dimensional ODE coupled in cascade using sampled‐in‐space ODE state measurements. The proposed observer estimates the distributed states of the PDE and ODE along with unknown PDE parameters and spatial input.
