We study Nevai’s condition that for orthogonal polynomials on the real line, Kn(x, x0)Kn(x0, x0)−1 dρ(x) → δx0 , where Kn is the Christoffel–Darboux kernel. We prove that it holds for the Nevai class of a finite gap set uniformly on the spectrum, and we provide an example of a regular measure on [−2,2] where it fails on an interval.

Diagnostics of faults in gears requires development of reliable condition indicators. A large number of condition indicators, which are based on statistical moments of the synchronous average and its derivatives (difference and residual signals) were previously suggested. This study evaluates the efficiency of different gear condition indicators that are based on statistical moments and compare...

While eye tracking is gaining popularity in IS research, pupillometry is relatively less explored in IS eye tracking studies. Research however suggests that pupillometry may serve as an excellent unobtrusive measure to study user information processing behavior. The Adaptive decision making theory asserts that task demand affects information processing behavior. Grounded in this theory, we argu...

Instruments based on airborne/structure borne ultrasound technology offer many opportunities for reducing energy waste and improving asset availability in plants. They expand the concept of ”Condition Monitoring” to include much more than basic mechanical fault inspections. Since these instruments detect friction, ionization and turbulence, their inspection capabilities range from trending bear...

The primary focus of this article is the provision of tests for additional conditional moment constraints in cross-section or short panel data contexts. The principal contribution is the explicit incorporation of conditional moment restrictions defining the maintained hypothesis in the formulation of the test statistics thus mirroring that of the classical parametric likelihood setting by defin...

OBJECTIVE: Men affected with Benign Prostate Hyperplasia (BPH) and Lower Urinary Tract Symptoms (LUTS) are demonstrating to require an increasing amount of attention from Urologists and Primary‐care Physicians. Over the years, common urological medications were based on either alpha‐blockers and/or 5alpha‐reductase inhibitors. During the last decade the phytotherapeutic drugs are gaining a more...

The Department of Defense has placed considerable emphasis on the identification of post-traumatic stress disorder (PTSD) in military personnel returning from Iraq and Afghanistan, and several mandatory screening tools are currently used by primary care clinicians to assist in this effort. PTSD has been shown to impair emotional and social functioning, and to affect physical health and quality ...

In this paper a new mixing condition for sequences of random variables is considered. This mixing condition is termed γ-mixing. Whereas mixing conditions such as α-mixing are typically defined in terms of entire σ-fields of sets generated by random variables in the distant past and future, γ-mixing is defined in terms of a smaller class of sets: the finite dimensional cylinder sets. This leads ...

We propose a scheme for classifying the entanglement of a tripartite pure qubit state. This classification scheme consists of an ordered list of seven elements. These elements are the Cayley hyper-determinant, and its six associated 2 × 2 subdeterminants. In particular we show that this classification provides a necessary and sufficient condition for separability.

45 eregulation of the energy market is bringing about a fundamental change in the way power equipment assets have to be operated, maintained and replaced. High power-equipment performance is key to cost-efficient energy trading and to the success of the efforts being made by utilities to satisfy end-user demand for high power quality . Three main trends are shaping power equipment life manageme...
