Constructing Boolean Functions Using Blended Representations
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.

A Class of Nonlinear Schrödinger Equations with Concentrated Nonlinearity
The authors of this interesting paper consider the one-dimensional nonlinear Schrödinger equation with a nonlinearity concentrated in a finite number of points. The Schrödinger equation has the form: \[ i(\partial /\partial t)\psi (t)=-\triangle \psi (t)+\sum_{j=1}^n\alpha _j(t)\delta _{y_j}\psi (t), \quad \psi (0)=\psi _0, \] where \(\delta _{y_j ...

Testing for ARCH in the Presence of Nonlinearity of Unknown Form in the Conditional Mean [PDF]
Tests of ARCH are a routine diagnostic in empirical econometric and financial analysis. However, it is well known that misspecification of the conditional mean may lead to spurious rejections of the null hypothesis of no ARCH.

Objective Despite guideline recommendations, long‐term glucocorticoid (GC) use is common in rheumatoid arthritis (RA). We conducted a clinician survey nested within a large registry to identify patient and clinician factors associated with GC use. Methods Clinicians contributing patients to the CorEvitas Rheumatoid Arthritis Registry were surveyed ...

Asymptotically linear and superlinear elliptic equations with gradient terms
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

Ultrasonic Nonlinearity Evaluation of the Cracked Interface
This paper derives a novel analytical solution for acoustic nonlinearity evaluation of the cracked interface. When microcracks exist at the interface, the tensile and compressive effective moduli of the cracked interface are considered to be different ...
