From musk to body odor: Decoding olfaction through genetic variation. by Bingjie Li, Marissa L Kamarck, Qianqian Peng, Fei-Ling Lim, Andreas Keller, Monique A M Smeets, Joel D Mainland, Sijia Wang

“…In both populations, consistent with previous studies, we replicated three previously reported associations (β-ionone/OR5A1, androstenone/OR7D4, cis-3-hexen-1-ol/OR2J3 LD-band), but not for odors containing aldehydes, suggesting that olfactory phenotype/genotype studies are robust across populations. …”

Electronic Structure of Hydrogenated and Surface-Modified GaAs Nanocrystals: Ab Initio Calculations by Hamsa Naji Nasir, Mudar A. Abdulsattar, Hayder M. Abduljalil

“…This is attributed to the broken symmetry and surface passivating atoms that split surface degenerate states and adds new levels inside and around the valence band. Bond length and tetrahedral angle result from full geometrical optimization indicate good convergence to the ideal zincblende structure at the centre of hydrogenated nanocrystal. …”

Look-up table predistorter based on non-iterative algorithm and indirect learning architecture for TWTA by WANG Yong1, XIANG Xin1, 2

“…Compared with the conven-tional predistorter based on LUT, the proposed predistorter could process distortion data offline without minimum cost function to update the LUT, which lowers the processing requirement of the predistortion system and avoids convergence problem of adaptive algorithm. Simulation results show that the predistorter can reduce in-band distortion and spectrum regrowth greatly introduced by the nonlinear effects of TWTA.…”

Challenge and strategy of 5G radio optimization by Jun ZHOU, Xiao QUAN, Jianhui MA

“…The era of network convergence,terminal and business diversification in 5G stage is coming.The radio network will have the situation of coexistence of GSM/TDD/FDD/NB/pre5G/5G/WLAN multi-mode and 900 MHz/1 800 MHz/ F/D/E/A6-band 15 frequency points.Due to the layered service carrying,the existing 4G and 5G interact with each other,which needs to be taken into account.The network structure will be unprecedented complex,and the wireless optimization work situation will be severe.The difficulties and challenges of 5G radio optimization were analyzed,and the strategies to deal with 5G radio optimization was put forward.…”

Doppler Positioning Performance of LEO Mega Constellation by Yulu ZHANG, Zhen LI, Chuang SHI, Guifei JING

“…This paper proposed a Doppler-only point-solution algorithm and analyzed the Doppler positioning performance based on the Starlink constellation.The Doppler positioning accuracy was about 3～6 m.To achieve the meter-level positioning accuracy, the satellite position and velocity errors should be within several meters and several centimeters per second, respectively.The ionospheric delay rates of C-band signal would cause about 2 m error in Doppler positioning.The positioning error would increase by dozens of meters if there were no corrections for the tropospheric errors.To ensure convergence in the LEO-based Doppler positioning, the initial receiver position error should be less than 300 km when the satellites orbit at an altitude of 550 km.…”

Empirical research on the diffusion effect of ICT innovation diffusion and prediction in China by Wenyu HU, Wenju WANG

“…Based on the characteristics of information and communication technology (ICT) in China,an empirical study was made on the diffusion effect of ICT innovation using Bass extension model.The results show that the curve fitting estimation effect of genetic algorithm was remarkable.In addition,non-cumulative adopter model was used to empirically analyze the diffusion effect of ICT innovation from the aspects of technology evolution,business,region and provinces.It was concluded that innovation diffusion was significantly driven by innovation effect along with the evolution of ICT,especially 3G/4G,broadband Internet,digital TV and their convergent business.Finally,the non-cumulative Bass model using genetic algorithm were used to predict the user size of fixed-line,mobile,broad-band,radio and television in the next five years.…”
