We calculate semiparametric efficiency bounds for a partially linear single-index model using a simple method developed by [1]. We show that this model can be used to evaluate the efficiency of several existing estimators.

Light trapping in subwavelength semiconductor nanowires (NWs) offers a promising approach to simultaneously reducing material consumption and enhancing photovoltaic performance. Nevertheless, the absorption efficiency of a NW, defined by the ratio of optical absorption cross section to the NW diameter, lingers around 1 in existing NW photonic devices, and the absorption enhancement suffers from...

INTRODUCTION Bimanual hand coordination is very important in carrying out day to day activities like buttoning the shirt, driving, picking up objects. It depends on various factors like age, gender, education, intactness of central and peripheral nervous system, Occupation and lifestyle. AIM The aim of the study was to compare the efficiency of bimanual hand coordination between right handed ...

Compression Ratio (CR) and Logical Operation Time (LOT) are two major measures of the efficiency of bitmap indexing. Previous works by [5, 9, 10, 11] compare the performance of bitmap compression schemes conducted separately on logical operation time and compression ratio. This paper will describe these works and recommend for consideration a new matrix – overall efficiency indicator. The overa...
