Electromagnetic parameter retrieval from inhomogeneous metamaterials

We discuss the validity of standard retrieval methods that assign bulk electromagnetic properties, such as the electric permittivity epsilon and the magnetic permeability mu, fr...

A Generalization of Sampling Without Replacement From a Finite Universe

Abstract This paper presents a general technique for the treatment of samples drawn without replacement from finite universes when unequal selection probabilities are used. Two ...

Maximum Likelihood Approaches to Variance Component Estimation and to Related Problems

Abstract Recent developments promise to increase greatly the popularity of maximum likelihood (ml) as a technique for estimating variance components. Patterson and Thompson (197...

A Simple Cipher Governs DNA Recognition by TAL Effectors

TAL Order Xanthomonas bacteria attack their plant hosts by delivering their own transcription-activator–like (TAL) proteins into the plant cell nucleus and alter the plant's gen...

Magnetic Response of Metamaterials at 100 Terahertz

An array of single nonmagnetic metallic split rings can be used to implement a magnetic resonance, which arises from an inductor-capacitor circuit (LC) resonance, at 100-teraher...

Expectations, Performance Evaluation, and Consumers’ Perceptions of Quality

The author examines conceptual and operational issues associated with the “perceptions-minus-expectations” (P-E) perceived service quality model. The examination indicates that ...
