We describe the design, fabrication, and testing of an achromatic, athermalized quarterwave retarder, a key component for the Multiangle Spectro-Polarimetric Imager (MSPI), which is a candidate for the Aerosol-Cloud-Ecosystem (ACE) mission. The desired wavelength range of the instrument encompasses the UV, visible, near IR, and shortwave IR, extending from 355 nm to 2130 nm, with polarimetric c...

in this paper, based on the coupled-mode and carrier rate equations, a dynamic model and numerical analysis of a multi quantum well (mqw) chirped distributed feedback semiconductor optical amplifier (dfb-soa)  all-optical flip-flop is precisely derived. we have analyzed the effects of strains of qw and mqw and cross phase modulation (xpm) on the dynamic response, and rise and fall times of the ...

The correlation between female labor force participation rate (FPR) and total fertility rate (TFR) across developed countries has switched from negative to positive. This paper provides a structural explanation of the historical pattern via changes in substitutability between mother’s direct childcare and indirect market care. Analysis of a life-cycle model of married women’s labor supply and f...

The detection and correction of erroneous Chinese characters is an important problem in many applications. This paper proposed an automatic method for correcting erroneous Chinese characters. The method is divided into two parts, which separately handle two types of erroneous character: the occurrence of an erroneous character in a word length of one, and the occurrence in a word length of two ...
