Abstract ：
The frequency diverse array (FDA) can generate a range-angle-coupled beampattern by introducing an additional frequency shift to its array element. The FDA has gained more and more attention due to its superiority over traditional phased array. However, different from phased arrays, frequency offset exists in the FDA as a unique parameter, its error will unavoidably affect the performance of the array, but current publications barely investigate into it. In this article, an approach based on interval analysis is proposed to analyze the tolerance of the power pattern, which is caused by the deviation of frequency offset in the manufacturing process. Numerical simulations are implemented to validate the proposed method and point out its characteristics and potential.

Abstract ：
当代青年是与网络联接最为紧密的群体，网络生活改变着他们的符号消费行为。符号消费动机可分为社会性和个我性两类。网络化和图像化转变或再造了消费的环境因素，如社会文化、消费情境、享用情境等，它们对青年符号消费两类动机的影响是不同的，总体来说，对阶层和财富炫耀倾向有抑制作用，对个性价值、审美需求有强化作用。通过消费行为表象探察当代青年特有的心理与情感诉求，从社会规范约束和学校教育等方面顺应积极趋势、杜绝不良商业诱导，可以更有效地引领青年群体形成积极健康的社会心态。

Abstract ：
Mosaic synthetic aperture radar (SAR) can achieve high resolution and wide swath (HRWS) imaging by steering its antenna beam elaborately. However, its unique time-frequency diagram and radiometric variation challenge the imaging. The conventional methods cannot be applied to mosaic SAR imaging directly. To address these problems, this article takes the imaging geometry into consideration, utilizing time frequency transform to suppress the spectrum ambiguity. Then, the azimuth nonlinear chirp scaling (NCS) algorithm is performed to compensate the variant modulation and the pattern weighting approach is used to correct the radiometric variance. Simulation results verify the effectiveness of the spectrum analysis and the proposed imaging algorithm.

Abstract ：
Different from traditional phased array (PA), frequency diverse array (FDA) employs an additional frequency offset to its array element so that the transmitted signal is angle-range-dependent. Therefore, FDA can be utilized to realize directional modulation (DM) in both angle and range dimensions. However, traditionalDMis mainly realized through optimization methods, which is time-consuming. This article proposes an analytical method to address this problem. For a transmitter withM + 1 elements, the proposed approach adopts a chaotic sequence to map out the frequency offsets and the weights of the first M elements. Then, the weight of the last element can be determined in an analyticalway. Numerical simulations are implemented to validate the proposed approach.

Abstract ：
Different from the conventional phased array radar, a frequency diverse array (FDA) applies additional frequency shift across the array elements, yielding a range-angle-dependent transmit beampattern that provides a huge potential opportunity for target estimation and range-dependent clutter and interference suppression. Generally, the conventional FDA employs a linear small frequency increment, forming a time-varying "S"-shape range-angle beampattern, which is range-angle coupled. In this article, a range-angle transmit beampattern synthesis method for FDA based on frequency offset optimization is proposed. Particle swarm optimization (PSO) is adopted in the FDA element frequency increment design to achieve a dot-shaped transmit beampattern. Meanwhile, matched weights are designed for time-modulation compensation. Numerical simulation results demonstrate that the proposed approach achieves better time-invariant performance over other FDA frameworks.

Abstract ：
The range-angle-dependent beampattern of frequency diverse array (FDA) makes it capable of dealing with range-dependent interference, which cannot be handled by conventional phased array. However, current publications pay more attention to the dot-shaped beam forming, which is not suitable for the range-dependent jamming signal suppression. To address this problem, this paper proposes a weight designing method to control the nulls distribution among range bins in the mainbeam. With the additional degrees of freedom provided by FDA, it is possible to flexibly adjust the positions and notch widths of the range nulls. The performance and effectiveness of the proposed weighted FDA are validated with numerical simulations.

Abstract ：
Tetrastigma hemsleyanum Diels et Gilg (THDG) is used as a Chinese traditional anti-inflammatory medicine for about thousands of years. In this work, Tetrastigma hemsleyanum Diels et Gilg's polysaccharide (TP) can inhibit E. coli's growth in initial dosing period. Compared with the antibacterial effect of Achyranthe's polysaccharide (AP) from their metabolic profile, it's obviously that their metabolic sites for E. coli were inconsistent. Moreover, TP could not only increase the level of fructose-6-phosphate (F6P), decrease the level of fructose-1,6-diphosphate (FBP), but also charge the amount of the two differential metabolic with the change of the concentration and the dosing time. Actually, F6P could transform into FBP by catalyze of 6-phosphofructokinase-1(6-PFK-1), which is an important process in glycolysis. Furthermore, FBP was considered have positively correlated with E. coifs growth rate. Therefore, TP can inhibit the E. coli's proliferation by interfering with the process for glycolysis and gluconeogenesis. Based on the experimental result, we proposed a new mouthwash method to evaluate the anti-bacterial activity. Compared with AP, TP can inhibit the E. coli's growth within 2 h with a low concentration (0.5%) and a short dosing time (5 min). This study extends the applications of THDG and establishes a new assessment method for the pharmacology activity of Chinese herbal medicine. (C) 2019 Elsevier B.V. All rights reserved.
