| 1 | Point mass filter based matching algorithm in gravity aided underwater navigation显示文摘Gravity-aided inertial navigation is a hot issue in the applications of underwater autonomous vehicle(UAV). Since the matching process is conducted with a gravity anomaly database tabulated in the form of a digital model and the resolution is 2' × 2',a filter model based on vehicle position is derived and the particularity of inertial navigation system(INS) output is employed to estimate a parameter in the system model. Meanwhile, the matching algorithm based on point mass filter(PMF) is applied and several optimal selection strategies are discussed. It is obtained that the point mass filter algorithm based on the deterministic resampling method has better practicability. The reliability and the accuracy of the algorithm are verified via simulation tests. | HAN Yurong WANG Bo DENG Zhihong FU Mengyin | 2018 | Journal of Systems Engineering and Electronics2018，29，1： | 7 |
| 2 | The RppC-AvrRppC NLR-effector interaction mediates the resistance to southern corn rust in maize显示文摘Southern corn rust(SCR),caused by the fungal pathogen Puccinia polysora,is a major threat to maize pro-duction worldwide.Efficient breeding and deployment of resistant hybrids are key to achieving durable control of SCR.Here,we report the molecular cloning and characterization of RppC,which encodes an NLR-type immune receptor and is responsible for a major SCR resistance quantitative trait locus.Further-more,we identified the corresponding avirulence effector,AvrRppC,which is secreted by P.polysora and triggers RppC-mediated resistance.Allelic variation of AvrRppC directly determines the effectiveness of RppC-mediated resistance,indicating that monitoring of AvrRppC variants in the field can guide the rational deployment of RppC-containing hybrids in maize production.Currently,RppC is the most frequently deployed SCR resistance gene in China,and a better understanding of its mode of action is crit-ical for extending its durability. | Ce Deng April Leonard James Cahill Meng Lv Yurong Li Shawn Thatcher Xueying Li Xiaodi Zhao Wenjie Du Zheng Li Huimin Li Victor Llaca Kevin Fengler Lisa Marshall Charlotte Harris Girma Tabor Zhimin Li Zhiqiang Tian Qinghua Yang Yanhui Chen Jihua Tang Xintao Wang Junjie Hao Jianbing Yan Zhibing Lai Xiaohong Fei Weibin Song Jinsheng Lai Xuecai Zhang Guoping Shu Yibo Wang Yuxiao Chang Weiling Zhu Wei Xiong Juan Sun Bailin Li Junqiang Ding | 2022 | Molecular Plant2022，15，5： | 6 |
| 3 | Assembly-enhanced triplet-triplet annihilation upconversion in the aggregation formed by Schiff-base Pt(Ⅱ) complex grafting-permethyl-β-CD and 9,10-diphenylanthracence dimer显示文摘Water-soluble triplet sensitizer with permethyl-β-cyclodextrin(PMCD)grafting on a Schiff-base Pt(II)complex(Pt-2),in which PMCD unit serves as a host for binding the acceptors and the Schiff-base Pt(II)complex serves as a triplet sensitizer,was synthesized to investigate the effect of supramolecular complexation and assembly on the triplet-triplet annihilation upconversion emission in water.9,10-Diphenylanthracence(DPA)carboxylate(A-1)and its dimer(A-2)in which two DPA carboxylate were covalently linked with an alkyl chain were synthesized as triplet acceptors which also play a role of guest molecules for PMCD.A-1 and A-2 showed high affinity with PMCD,and A-2 can readily aggregate in water and form micron sized assemblies due to the hydrophobic effect andπ-πstacking of anthracene core in A-2.The efficiency of TTA-UC was demonstrated to be enhanced by a synergistic effect of host-guest complexation of Pt-2 with A-2 and the self-aggregation of the acceptor A-2,which facilitated the energy transfer and energy fusion among donor and acceptor. | Hongxia Lai Ting Zhao Yurong Deng Chunyin Fan Wanhua Wu Cheng Yang | 2019 | Chinese Chemical Letters2019，30，11： | 1 |

| 5 | Accumulation, transportation, and distribution of tetracycline and cadmium in rice显示文摘Co-exposure to heavy metal and antibiotic pollution might result in complexation and synergistic interactions,affecting rice growth and further exacerbating pollutant enrichment.Therefore,our study sought to clarify the influence of different Tetracycline (TC) and Cadmium(Cd) concentration ratios (both alone and combined) on rice growth,pollutant accumulation,and transportation during the tillering stage in hydroponic system.Surprisingly,our findings indicated that the interaction between TC and Cd could alleviate the toxic effects of TC/Cd on aerial rice structures and decrease pollutant burdens during root elongation.In contrast,TC and Cd synergistically promoted the accumulation of TC/Cd in rice roots.However,their interaction increased the accumulation of TC in roots while decreasing the accumulation of Cd when the toxicant doses increased.The strong affinity of rice to Cd promoted its upward transport from the roots,whereas the toxic effects of TC reduced TC transport.Therefore,the combined toxicity of the two pollutants inhibited their upward transport.Additionally,a low concentration of TC promoted the accumulation of Cd in rice mainly in the root tip.Furthermore,a certain dose of TC promoted the upward migration of Cd from the root tip.Laser ablation-inductively coupled plasma mass spectrometry demonstrated that Cd mainly accumulated in the epidermis and stele of the root,whereas Fe mainly accumulated in the epidermis,which inhibited the absorption and accumulation of Cd by the rice roots through the generation of a Fe plaque.Our findings thus provide insights into the effects of TC and Cd co-exposure on rice growth. | Chunfeng He Jini Zhou Chen Yang Zhiyi Song Junheng He Ziqing Huang Yurong Deng Jinling Wang Yu Xiong Zhi Dang | 2023 | Journal of Environmental Sciences2023，，4： | 1 |

| 7 | Protective Effects of Flavonoids from Pteridium aquilinum on CCl_(4)-induced Acute Liver Injury in Mice显示文摘[Objectives]To explore the protective effects of flavonoids from Pteridium aquilinum(PAFL)on carbon tetracholoride(CCl_(4))-induced acute liver injury in mice and its potential mechanism.[Methods]All mice were randomly divided into four groups(n=10 in each),normal group,CCl_(4)group,CCl_(4)+PAFL groups[treated with PAFL(50 or 200 mg/kg)].Animal treatment was continued for 7 consecutive days.The blood was collected after injection of CCl_(4)for 24 h,and the liver tissue was removed from the mice and stored at-80℃.[Results]The PAFL(50 and 200 mg/kg)significantly inhibited the increase of aspartate aminotransferase(AST)and alanine aminotransferase(ALT)levels in serum caused by CCl_(4)treatment.PAFL administration not only increased the activity of antioxidant enzymes superoxide dismutase(SOD),Glutathione(GSH)and catalase(CAT)in mice,but also reduced the level of malondialdehyde(MDA).Meanwhile,PAFL administration decreased the expression of nuclear factor-kappa B(NF-κB)and Cyclooxygenase-2(COX-2)proteins and inhibited the release of pro-inflammatory factors tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β)and interleukin 6(IL-6).In addition,PAFL(200 mg/kg)treatment down-regulated extracellular regulated protein kinases(ERK)and c-Jun N-terminal kinase(JNK)protein levels in liver tissue.[Conclusions]These findings clearly indicate that the protective effects of PAFL on CCl_(4)-induced acute liver injury is related to its antioxidant and anti-inflammatory activity,which may be mediated by NF-κB and MAPKs signaling pathways. | Junyue ZHANG Xiang HAN Qi ZHANG Yurong ZHU Haowei DENG Hongyang LIU Shuangli LIU Xiaohui WANG | 2022 | Medicinal Plant2022，13，6： | 0 |
| 8 | Preventing HIV Epidemic in China:Policy Evolution and Coordination Mechanisms in the Past Four Decades显示文摘China has achieved commendable success in stabilizing human immunodeficiency virus(HIV)prevalence at a relatively low level of transmission(1).Nevertheless,the total number of people living with HIV in China rose to approximately 1.05 million,with cumulative reported acquired immune deficiency syndrome(AIDS)-related fatalities reaching 351,000 by the end of 2020(2).Since the initial infiltration of HIV into China in 1982(3),the nation has enacted over 471 national policies through 2021 to combat the epidemic.Initially,the outbreak was perceived primarily as a healthcare issue rather than the complex societal challenge that it manifested into.The Ministry of Health(MOH,now known as National Health Commission)was initially tasked with HIV prevention,issuing the nation’s first HIV/AIDS-related policy in 1984,which aimed to ban HIV-infected products and individuals from entry.Regrettably,this approach proved inadequate as significant HIV outbreaks unfolded.At this juncture,the State Council Research Office recognized the HIV epidemic as a grave societal and public health issue,posing a threat to the“Survival of the Chinese Nation”(4).Engagement at a higher governmental level became imperative to coordinate an effective response across diverse administrative agencies. | Yanli Liu Yurong Zhang Xiaoxin Xu Zhidi Deng Xiaobo Wang Duozhen Yuan Zelin Xue Xiulan Zhang | 2023 | China CDC weekly2023，5，48： | 0 |
| 9 | Ascorbic acid derived carbon dots promote circadian rhythm and contribute to attention deficit hyperactivity disorder显示文摘Attention deficit hyperactivity disorder(ADHD)is one of the most prevalent psychiatric disorders in children,and ADHD patients always display circadian abnormalities.While,the ADHD drugs currently used in clinic have strong side effects,such as psychosis,allergic reactions,and heart problems.Here,we demonstrated carbon dots derived from the ascorbic acid(VCDs)could strongly rescue the hyperactive and impulsive behaviour of a zebrafish ADHD disease model caused by per1b mutation.VCDs prolonged the circadian period of zebrafish for more than half an hour.In addition,the amplitude and circadian phase were also changed.The dopamine level was specifically increased,which may be caused by stimulation of the dopaminergic neuron development in the midbrain.Notably,it was found that the serotonin level was not altered by VCDs treatments.Also,the gene transcriptome effects of VCDs were discussed in present work.Our results provided the dynamic interactions of carbon dots with circadian system and dopamine signaling pathway,which illustrates a potential application of degradable and bio-safe VCDs for the treatment of the attention deficient and hyperactive disorder through circadian intervention. | Jian Huang Yun Wang Zhaomin Zhong Yurong Ma Keru Deng Changhong Liu Hui Huang Yang Liu Xin Ding Zhenhui Kang | 2022 | Nano Research2022，15，9： | 0 |
