Secure beamforming and deployment design for rate-splitting multiple access-based UAV communications

引用

Science China(Information Sciences) 2025年第1期68卷 342-356页

作者： Bing WANG Xiaofeng TAO Shujun HAN Huici WU Kai yang Zhu HAN National Engineering Research Center of Mobile Network Technologies Beijing University of Posts and Telecommunications Peng Cheng laboratory Department of Electrical and Computer Engineering University of Houston

Rate-splitting multiple access(RSMA) has recently gained attention as a potential robust multiple access(MA)scheme for upcoming wireless networks. Given its ability to efficiently utilize wireless resources and design interference management strategies, it can be applied to unmanned aerial vehicle(UAV) networks to provide convenient services for large-scale access ground users. However, due to the line-of-sight(loS) broadcast nature of UAV transmission, information is susceptible to eavesdropping in RSMA-based UAV networks. Moreover, the superposition of signals at the receiver in such networks becomes complicated. To cope with the challenge, we propose a two-user multi-input single-output(MISO) RSMA-based UAV secure transmission framework in downlink communication networks. In a passive eavesdropping scenario, our goal is to maximize the sum secrecy rate by optimizing the transmit beamforming and deployment location of the UAV-base station(UAV-BS),while considering quality-of-service(QoS) constraints, maximum transmit power, and flight space limitations. To address the non-convexity of the proposed problem, the optimization problem is first decoupled into two subproblems. Then, the successive convex approximation(SCA) method is employed to solve each subproblem using different propositions. In addition, an alternating optimization(AO)-based location RSMA(l-RSMA) beamforming algorithm is developed to implement joint optimization to obtain the suboptimal solution. Numerical results demonstrate that(1) the proposed l-RSMA scheme yields a28.97% higher sum secrecy rate than the baseline l-space division multiple access(SDMA) scheme;(2) the proposed l-RSMA scheme improves the security performance by 42.61% compared to the l-non-orthogonal multiple access(NOMA) scheme.

Identification of long InDels through whole genome resequencing to fine map qIF05-1 for seed isoflavone content in soybean(Glycine max l. Merr.)

Soybean seed isoflavones are a type of secondary metabolites that can provide health and nutrition benefits for humans. In our previous study, a stable quantitative trait locus(QTl) qIF05-1 controlling the seed isoflavone content in soybean was detected on chromosome(Chr.) 05 in a recombinant inbred line(RIl) population from a cross of Huachun 2×Wayao. In this study, the parental lines were re-sequenced using the Illumina Solexa System with deep coverage. A total of 63,099 polymorphic long insertions and deletions(InDels)(≥15 bp)were identified between the parents Huachun 2 and Wayao. The InDels were unevenly distributed on 20chromosomes of soybean, varying from 1,826 in Chr. 12 to 4,544 in Chr. 18. A total of 10,002 long InDels(15.85% of total) were located in genic regions, including 1,139 large-effect long InDels which resulted in truncated or elongated protein sequences. In the qIF05-1 region, 68 long InDels were detected between the two parents. Using a progeny recombination experiment and genotype analysis, the qIF05-1 locus was mapped into a 102.2 kb genomic region, and this region contained 12 genes. By RNA-seq data analysis, genome sequence comparison and functional validation through ectopic expression in Arabidopsis thaliana, Glyma.05G208300(described as GmEGl3), which is a basic helix-loop-helix(bHlH) transcription factor in plants, emerged as the most likely confirmed gene in qIF05-1. These long InDels can be used as a type of complementary genetic method for QTl fine mapping, and they can facilitate genetic studies and molecular-assisted selection breeding in soybean.

Combined physiological and pathway analysis revealed the effect of Sporisorium destruens on photosynthesis in broomcorn millet(Panicum miliaceum l.)

引用

Journal of Integrative Agriculture 2025年第3期 1065-1079页

作者： Fei Jin lei Xu Zhihu lü Yuchuan Zhang Qinghua yang Qingfang Han Baili Feng College of Agronomy Northwest A&F University Key laboratory of Crop Physiology Ecology and Tillage Science in Northwestern Loess Plateau of Ministry of Agriculture and Rural AffairsNorthwest A&F University State Key laboratory of Crop Stress Biology for Arid Areas Northwest A&F University

Photosynthesis is the basis of crop growth and is sensitive to stress. Smut(Sporisorium destruens) is the primary disease in the production of broomcorn millet(Panicum miliaceum l.). This study evaluated the effects of infection with S. destruens on the photosynthesis of the resistant cultivar(BM) and susceptible cultivar(NF). After inoculation, there was a decrease in the chlorophyll content, gas exchange parameters, and chlorophyll fluorescence of the two cultivars. Observation of the ultrastructure of diseased leaves showed that the chloroplasts and mitochondria had abnormal morphology, and some vacuoles appeared. RNA-seq was performed on the flag leaves after inoculation. In addition to the resistant and susceptible cultivars, the diseased leaves developed from inflorescences were defined as S2. The analysis showed that the pathways related to photosynthesis stimulated some differentially expressed genes(DEGs) after infection with S. destruens. More DEGs were induced in the susceptible broomcorn millet NF than in the resistant broomcorn millet BM, and most of those genes were downregulated. The number of DEGs induced by S2 was greater than that in susceptible cultivar NF, and most of them were upregulated. These results indicate that infection with S. destruens affects the normal photosynthetic performance of broomcorn millet. Understanding the mechanism between S. destruens, photosynthesis, and broomcorn millet is an effective measure to prevent the occurrence of smut and enhance its resistance.
