Moreover, we will suggest a possible u...

PURPOSE Compare performance of normalized reflectance index (NRI) and retinal nerve fiber layer thickness (RNFLT) parameters determined from optical coherence tomography (OCT) images for glaucoma and glaucoma suspect diagnosis. METHODS Seventy-five eyes from 71 human subjects were studied: 33 controls, 24 glaucomatous, and 18 glaucoma-suspects. RNFLT and NRI maps were measured using 2 custom-...

BACKGROUND The response of primary breast cancer to chemotherapy is usually expressed either as a pathological complete remission (pCR) or as 'no pCR'. A more quantitative measure is called for. PATIENTS AND METHODS The 'neoadjuvant response index' (NRI) was calculated by adding a breast response score (a number from a five-point scale) to an axillary response score (a number from a three-poi...

BACKGROUND The Net Reclassification Index (NRI) and its P value are used to make conclusions about improvements in prediction performance gained by adding a set of biomarkers to an existing risk prediction model. Although proposed only 5 years ago, the NRI has gained enormous traction in the risk prediction literature. Concerns have recently been raised about the statistical validity of the NRI...

The recent interest in negative refractive-index (NRI) metamaterials stems from Veselago’s early work predicting media that simultaneously exhibit negative permittivity and negative permeability. Metamaterial structures, such as split-ring resonator and stripwires and planar-loaded transmission line grids, are artificial dielectrics, made of periodically arranged inclusions. Thus, the design of...

The application of the Finite Difference Time Domain technique, equipped with periodic boundary conditions, can lead to the fast full-wave characterization of negative refractive index (NRI) structures. Employing the so-called sine-cosine method, the guiding and radiating properties of the NRI transmission-line medium are determined. Surface wave effects are captured, while the operation of the...

An effective negative refractive index (NRI) is demonstrated and experimentally verified for the first two propagation bands of a fishnet-like metamaterial at millimeter-wave frequencies. The dual-band NRI behavior is achieved by engineering the diffraction order (±1, ±1) associated with the internal mode supported between holey layers to correspond with the second propagation band. In addition...

A high gain patch antenna inspired by 4 layers of negative refractive index (NRI) metamaterial (MTM) superstrate is proposed to operate at downlink radio frequency (RF) band (935MHz to 960MHz) of GSM 900). The MTM unit cell consists of a nested split ring resonator (SRR) on one side and strip line laminated on other side of FR4 substrate. The effective permeability and permittivityof the unit c...
