Revista Colombiana de Estadística, 2008 The election of the smoothing parameter or bandwidth is, probably, the most important concern in the statistical smoothed techniques. The relevance of this parameter, on the obtained results difficult, the use of these methods in statistical inference ...

Intelligent Acousto‐Electrical Metamaterials (IAM) for Sound Source Detection
Advanced Materials, EarlyView.Our proposed metamaterial concept enables sound source detection using a single material, in contrast to conventional arrays that require dozens or even hundreds of transducers. We show that the coupled acoustic–vibrational–electrical responses in piezoelectric metamaterials give rise to topology‐governed charge transport, producing distinct voltage ...

Metamaterial Antennas Enhance MRI of the Eye and Occipital Brain
Advanced Materials, EarlyView.A radiofrequency antenna platform comprising planar and bend configurations is developed, incorporating structurally integrated epsilon‐negative metamaterial unit cells to enhance MRI. These antennas enable high‐resolution in vivo human MRI of the eye, orbit, and occipital brain. Comprehensive validation, including simulations, phantom experiments, SAR,

Optimal Bandwidth Choice for the Regression Discontinuity Estimator [PDF]
We investigate the problem of optimal choice of the smoothing parameter (bandwidth) for the regression discontinuity estimator. We focus on estimation by local linear regression, which was shown to be rate optimal (Porter, 2003).

Arm‐Length‐Controlled CsPbBr3 Nanocrystals for Tunable Optical and Assembly Behavior
Advanced Materials, EarlyView.In this work, the synthesis parameters that dictate the formation of armed CsPbBr3 nanocrystals are described, and routes enabling precise control over arm length are proposed. Direct links between morphology and optoelectronic behavior are established.

Variational methods in simultaneous optimum interpolation and initialization [PDF]
The duality between optimum interpolation and variational objective analysis, is reviewed. This duality is used to set up a variational approach to objective analysis which uses prior information concerning the atmospheric spectral energy distribution ...
