Angle-sensitive Pixels Based on Subwavelength Compound Gratings
Yunlong Meng,Xuemei Hu,Cheng Yang,Xinyu Shen,Xueyun Cao,Lankun Lin,Feng Yan,Tao Yue 한국광학회 2022 Current Optics and Photonics Vol.6 No.4
In this paper, we present a new design for angle-sensitive pixels (ASPs). The proposed ASPs take advantage of subwavelength compound gratings to capture the light angle, which enables pixel size to reach the wavelength scale of 0.7 μm × 0.7 μm. The subwavelength compound gratings are implement-ed by the wires of the readout circuit inherent to the standard complementary metal–oxide–semiconductor manufacturing process, thus avoiding additional off-chip optics or post-processing. This technique allows the use of two pixels for horizontal or vertical angle detection, and can determine the light’s angle in the range from −45° to +45°. The proposed sensor enables surface-profile reconstruction of mi-croscale samples using a lensless imaging system.
Evaluating the Market Potential for Mobile Phone Service in Chinese Provinces
남찬기,이홍규,Bin Duan,Xuemei Meng,김성철 에스케이텔레콤 (주) 2008 Telecommunications Review Vol.18 No.5
The Chinese mobile phone market has enjoyed impressive growth, however, each province in China shows different progresses. This article examines several factors explaining the different mobile phone adoption rates and presents the most efficient point of mobile phone service adoption in 31 provinces of China, based on national statistic data from 2001 through 2007, using the Stochastic Frontier Analysis Model. The results show that fixed phone penetration, network capacity, occupation structure, disposable income, and geographic location are the important factors that may influence the mobile phone adoption rate in each province. The results also present the relative market potential of each province by calculating the most efficient point of mobile phone adoption. In particular, our results imply that the market potentials are still big not only in the rich Yangtze River delta region such as Shanghai, Zhejiang and Jiangsu but also in the rural central and western areas.

The 23-valent polysaccharide vaccine and the 7-valent pneumococcalconjugate vaccine are licensed vaccines that protectagainst pneumococcal infections worldwide. However,the incidence of pneumococcal diseases remains high in lowincomecountries. Whole-cell vaccines with high safety andstrong immunogenicity may be a favorable choice. We previouslyobtained a capsule-deficient Streptococcus pneumoniaemutant named SPY1 derived from strain D39. As anattenuated live pneumococcal vaccine, intranasal immunizationwith SPY1 elicits broad serotype-independent protectionagainst pneumococcal infection. In this study, forsafety consideration, we inactivated SPY1 with 70% ethanoland intranasally immunized BALB/c mice with killed SPY1plus cholera toxin adjuvant for four times. Results showedthat intranasal immunization with inactivated SPY1 inducedstrong humoral and cellular immune responses. Intranasalimmunization with inactivated SPY1 plus cholera toxin adjuvantelicited effective serotype-independent protection againstthe colonization of pneumococcal strains 19F and 4 as well aslethal infection of pneumococcal serotypes 2, 3, 14, and 6B. The protection rates provided by inactivated SPY1 againstlethal pneumococcal infection were comparable to those ofcurrently used polysaccharide vaccines. In addition, vaccinespecificB-cell and T-cell immune responses mediated theprotection elicited by SPY1. In conclusion, the 70% ethanolinactivatedpneumococcal whole-cell vaccine SPY1 is a potentiallysafe and less complex vaccine strategy that offersbroad protection against S. pneumoniae.

Background Taste preference varies geographically in China. However, studies on Chinese people’s taste preference in different regions of China are limited, and are lack of research on the mechanism of diferences in taste preference, especially in genetics. Objective This study aims to investigate the characteristics of taste preference of Chinese men, and estimate whether diverse taste preference in Chinese have genetic underpinning. Methods We conducted a questionnaire survey on taste preferences on 1076 males from 10 regions of China, and collected another 1427 males from the same regions which genotyped by microarray. We compared the correlation between diferent taste preference, and evaluated the correlation between the mutation frequency of inhouse database and diferent taste preference. The putative taste-preference-related genes were further utilized to estimate the candidate relationship on gene and gene network in diferent taste preference. Results There was a correlation between diferent taste preferences in Chinese men. We found 31 SNPs associated with 6 kind of taste preferences. These SNPs located within or nearby 36 genes, and the tastes associated with 4 of these genes (TRPV1, AGT, ASIC2 and GLP1R) are consistent with the previous studies. Moreover, in diferent tastes which were suggested to be associated with each other, some putative related genes were the same or in the same gene network, such as pathways related with blood pressure, response to stimulus and nervous system. Conclusions This study indicates that the diverse taste preference of Chinese men may have genetic underpinning.
