1Barometric altimetry system as virtual constellation applied in CAPS显示文摘This work describes the barometric altimetry as virtual constellation applied to the Chinese Area Positioning System (CAPS), which uses the transponders of communication satellites to transfer navigation messages to users. Barometric altimetry depends on the relationship of air pressure varying with altitude in the Earth’s atmosphere. Once the air pressure at a location is measured the site altitude can be found. This method is able to enhance and improve the availability of three-dimensional positioning. The difficulty is that the relation between barometric pressure and altitude is variable in different areas and under various weather conditions. Hence, in order to obtain higher accuracy, we need to acquire the real-time air pressure corresponding to an altimetric region’s reference height. On the other hand, the altimetry method will be applied to satellite navigation system, but the greatest difficulty lies in how to get the real-time air pressure value at the reference height in the broad areas overlaid by satellite navigation. We propose an innovational method to solve this problem. It is to collect the real-time air pressures and temperatures of the 1860 known-altitude weather observatories over China and around via satellite communication and to carry out time extrapolation forecast uniformly. To reduce data quantity, we first partition the data and encode them and then broadcast these information via navigation message to CAPS users’ receivers. Upon the interpolations being done in receivers, the reference air pressure and temperature at the receiver’s nearby place is derived. Lastly, combing with the receiver-observed real air pressure and temperature, the site’s altitude can be determined. The work is presented in the following aspects: the calculation principle, formulae, data collection, encoding, prediction, interpolation method, navigation message transmission together with errors causes and analyses. The advantages and shortcomings of the technique are discussed at the end.AI GuoXiang SHENG PeiXuan DU JinLin ZHENG YongGuang CAI XianDe WU HaiTao HU YongHui HUA Yu LI XiaoHui 2009Science China(Physics,Mechanics & Astronomy)2009,52,3:22
2V4C3Tx MXene:A promising active substrate for reactive surface modification and the enhanced electrocatalytic oxygen evolution activity显示文摘Presented are the synthesis,characterizations,and reactive surface modification(RSM)of a novel nine atomic layered V4C3Tx MXene.With the advantages of the multilayered V4C3Tx MXene that can simultaneously support the RSM reaction and keep the inner skeleton stable,a series of amorphous Ni/Fe/Vternary oxide hydroxides thin layer can be successfully modified on the surface of the V4C3Tx MXene(denoted as MOOH@V4C3Tx,M=Ni,Fe,and V)without disrupting its original structure.Attributed to the in situ reconstruction of highly active oxide hydroxide layer,the nanohybrids exhibited an enhanced oxygen evolution reaction(OER)activity and excellent long-time stability over 70 hours.In particular,a current density of 10 mA cm−2 can be reached by the nanohybrid with the optimized Ni/Fe ratio at an overpotential(η)as low as 275.2 mV,which is comparable to most of the state-of-the-art OER catalysts and better than other MXene-based derivatives.Demonstrated by the tunable physicochemical properties and excellent structural stability of these nanohybrids,we may envision the promising role of the M4X3-based MXenes as substrates for a wide range of energy conversion and storage materials.Cheng-Feng Du Xiaoli Sun Hong Yu Wei Fang Yao Jing Yonghui Wang Shuiqing Li Xianhu Liu Qingyu Yan 2020InfoMat2020,2,5:8
3FAK-targeting PROTAC as a chemical tool for the investigation of non-enzymatic FAK function in mice显示文摘Dear Editor,Animal models,most commonly mice,that lack a protein of interest play an important role in phenotypic and functional studies of a target gene,allowing researchers to answer various biological questions(Chaible et al,2010).At pre-sent,a variety of tools act at the DNA or RNA level to enable researchers to model gene function(and thus protein)deficiency,including nucleic acid based RNA interference(EI-bashir et al.,2001),antisense oligonucleotides(Schoch and Miller,2017),and genome editing-based CRISPR-Cas9(Doudna and Charpentier,2014)strategies.However,challenges remain.Hongying Gao Chunwei Zheng Jian Du Yue Wu Yonghui Sun Chunsheng Han Kehkooi Kee Yu Rao 2020Protein & Cell2020,11,7:5
4Sedimentology and Sequence Stratigraphy of Marine to Lacustrine Deltaic Deposits in a Craton Basin and Their Controlling Factors: Shan 2 Member–He 8 Member(Guadalupian–Lopingian, Permian), Southeast Ordos Basin, North China显示文摘The Shan 2 Member, Shan 1 Member and He 8 Member of the Mid–Late Permian Shanxi and lower Xiashihezi formations, in the southeastern Ordos Basin, together comprise ~150 m of deltaic deposits. This sequence records an overall evolution from deep marine environment to shallow lake associated with braided river, braided river delta and meandering river delta. Core description, well log interpretation, and stable isotope analysis, including carbon, oxygen and strontium, were conducted to understand the sedimentary evolution of Shan 2 to He 8 Member. The Shanxi Formation, which consists of the Shan 2 and Shan 1 members, is characterized by a tidal-influenced meandering river delta environment and a higher δ^(13)C value and ^(87)Sr?(^(86)Sr) ratio and a lower δ^(18)O value. The He 8 Member, the basal part of the Xiashihezi Formation, is featured by a braided river to braided river delta system and a lower δ^(13)C value, ^(87)Sr?(^(86)Sr) ratio, and a higher δ^(18)O value. Four third-order depositional sequences separated by five sequence boundaries are determined. Coarsening upward sequences of the Shan 2 Member–He 8 Member indicate a general regression trend, which can be correlated to global sea-level fall occurring during the Roadian–Wuchiapingian, as also evidenced by previous published zircon U–Pb results. The coal-bearing sequence(Shanxi Formation) to non-coal-bearing sequence(He 8 Member), as well as a decrease of ^(87)Sr?(^(86)Sr), suggest a trend from humid to arid climates. A combined effect of sea-level drop and a small uplift at the end of Shanxi Formation are proposed.SHAN Xin YU Xinghe Peter CLIFT LI Yalong JIN Lina SU Dongxu DU Yonghui ZHOU Jinsong HAN Xiaoqin 2018Acta Geologica Sinica(English Edition)2018,92,1:4

8Combined nanosuspensions from two natural active ingredients for cancer therapy with reduced side effects显示文摘Tumor drug resistance and systemic side effects of chemotherapeutic drugs are the main reasons for the failure of cancer treatment.In recent years,it was found that some natural active ingredients can reverse MDR and regulate body immunity to enhance the efficacy and reduce toxicity of chemotherapeutic drugs.In this paper,a new nanosuspensions,HCPT and QUR hybrid nanosuspensions(HQ-NPs),was prepared by the microprecipitation-high pressure homogenization method to reverse tumor drug resistance,reduce toxicity,and increase therapeutic efficacy.The in vitro investigation results showed that HQ-NPs had a unique shape(particle size was about 216.3±5.9 nm),changed crystalline,and different dissolution rates compared with HCPT-NPs and QUR-NPs,which is attributed to the strong intermolecular forces between HCPT and QUR as indicated by the results of the molecule dock.It was verified that the HQ-NPs could double the retention of HCPT in cells and enhance the cytotoxicity to A549/PTX cells in vitro tests compared with HCPT-NPs.We also found that HQ-NPs can significantly enhance the accumulation of HCPT in tumor sites,improve the antitumor activity of HCPT,and protect the immune organs and other normal tissues(P<0.01),compared with HCPT-NPs.Therefore,hybrid nanosuspensions can offer promising potential as the drug delivery system for HCPT and QUR to increase the therapeutic efficacy and reduce the toxicity of HCPT.Yonghui Qiao Zhihao Wei Tingting Qin Rufeng Song Zhiqiang Yu Qi Yuan Juan Du Qingbing Zeng Lanlan Zong Shaofeng Duan Xiaohui Pu 2021Chinese Chemical Letters2021,32,9:1

10Phylogenetic analysis of aerobic anoxygenic phototrophic bacteria and their relatives based on farnesyl pyrophosphate synthase gene显示文摘The study aims to reveal phylogenetic and evolutionary relationship between aerobic anoxygenic phototrophic bacteria(AAnPB) and their relatives,anaerobic anoxygenic phototrophic bacteria(AnAnPB) and nonphototrophic bacteria(NPB,which had high homology of 16S rDNA gene with AAnPB and fell into the same genus),and validate reliability and usefulness of farnesyl pyrophosphate synthase(FPPS) gene for the phylogenetic determination.FPPS genes with our modified primers and 16S rDNA genes with general primers,were amplified and sequenced or retrieved from GenBank database.In contrast to 16S rDNA gene phylogenetic tree,AAnPB were grouped into two clusters and one branch alone with no intermingling with NPB and AnAnPB in the tree constructed on FPPS.One branch of AAnPB,in both trees,was located closer to outgroup species than AnAnPB,which implicated that some AAnPB would be diverged earlier in FPPS evolutionary history than AnAnPB and NPB.Some AAnPB and NPB were closer located in both trees and this suggested that they were the closer relatives than AnAnPB.Combination codon usage in FPPS with phylogenetic analysis,the results indicates that FPPS gene and 16S rRNA gene have similar evolutionary pattern but the former seems to be more reliable and useful in determining the phylogenic and evolutionary relationship between AAnPB and their relatives.This is the first attempt to use a molecular marker beside 16S rRNA gene for studying the phylogeny of AAnPB,and the study may also be helpful in understanding the evolutionary relationship among phototrophic microbes and the trends of photosynthetic genes transfer.FENG Fuying JIAO Nianzhi DU Hailian ZENG Yonghui 2010Acta Oceanologica Sinica2010,29,5:1
11Long noncoding RNA(lncRNA)H19:An essential developmental regulator with expanding roles in cancer,stem cell differentiation,and metabolic diseases显示文摘Recent advances in deep sequencing technologies have revealed that,while less than 2%of the human genome is transcribed into mRNA for protein synthesis,over 80%of the genome is transcribed,leading to the production of large amounts of noncoding RNAs(ncRNAs).It has been shown that ncRNAs,especially long non-coding RNAs(lncRNAs),may play crucial regulatory roles in gene expression.As one of the first isolated and reported lncRNAs,H19 has gained much attention due to its essential roles in regulating many physiological and/or pathological processes including embryogenesis,development,tumorigenesis,osteogen-esis,and metabolism.Mechanistically,H19 mediates diverse regulatory functions by serving as competing endogenous RNAs(CeRNAs),Igf2/H19 imprinted tandem gene,modular scaffold,cooperating with H19 antisense,and acting directly with other mRNAs or lncRNAs.Here,we summarized the current understanding of H19 in embryogenesis and development,cancer development and progression,mesenchymal stem cell lineage-specific differentiation,and metabolic diseases.We discussed the potential regulatory mechanisms underlying H19’s func-tions in those processes although more in-depth studies are warranted to delineate the exact molecular,cellular,epigenetic,and genomic regulatory mechanisms underlying the physiolog-ical and pathological roles of H19.Ultimately,these lines of investigation may lead to the development of novel therapeutics for human diseases by exploiting H19 functions.Junyi Liao Bowen Chen Zhenglin Zhu Chengcheng Du Shengqiang Gao Guozhi Zhao Piao Zhao Yonghui Wang Annie Wang Zander Schwartz Lily Song Jeffrey Hong William Wagstaff Rex CHaydon Hue HLuu Jiaming Fan Russell RReid Tong-Chuan He Lewis Shi Ning Hu Wei Huang 2023Genes & Diseases2023,10,4:1

14Ambient Temperature and Years of Life Lost:A National Study in China显示文摘Although numerous studies have investigated premature deaths attributable to temperature,effects of temperature on years of life lost(YLL)remain unclear.We estimated the relationship between temperatures and YLL,and quantified the YLL per death caused by temperature in China.We collected daily meteorological and mortality data,and calculated the daily YLL values for 364 locations(2013–2017 in Yunnan,Guangdong,Hunan,Zhejiang,and Jilin provinces,and 2006–2011 in other locations)in China.A time-series design with a distributed lag nonlinear model was first employed to estimate the location-specific associations between temperature and YLL rates(YLL/100,000 population),and a multivariate meta-analysis model was used to pool location-specific associations.Then,YLL per death caused by temperatures was calculated.The temperature and YLL rates consistently showed U-shaped associations.A mean of 1.02(95%confidence interval:0.67,1.37)YLL per death was attributable to temperature.Cold temperature caused 0.98 YLL per death with most from moderate cold(0.84).The mean YLL per death was higher in those with cardiovascular diseases(1.14),males(1.15),younger age categories(1.31 in people aged 65–74 years),and in central China(1.34)than in those with respiratory diseases(0.47),females(0.87),older people(0.85 in people R75 years old),and northern China(0.64)or southern China(1.19).The mortality burden was modified by annual temperature and temperature variability,relative humidity,latitude,longitude,altitude,education attainment,and central heating use.Temperatures caused substantial YLL per death in China,which was modified by demographic and regional characteristics.Tao Liu Chunliang Zhou Haoming Zhang Biao Huang Yanjun Xu Lifeng Lin Lijun Wang Ruying Hu Zhulin Hou Yize Xiao Junhua Li Xiaojun Xu Donghui Jin Mingfang Qin Qinglong Zhao Weiwei Gong Peng Yin Yiqing Xu Jianxiong Hu Jianpeng Xiao Weilin Zeng Xing Li Siqi Chen Lingchuan Guo Zuhua Rong Yonghui Zhang Cunrui Huang Yaodong Du Yuming Guo Shannon Rutherford Min Yu Maigeng Zhou Wenjun Ma 2021The Innovation2021,2,1:1
15Surface plasmon enhanced solar-blind photoresponse of Ga2O3 film with Ga nanospheres显示文摘Semiconductor solar-blind(220-280 nm)photodetectors(PDs),which have important applications both in civil and military aspects,are mainly based on diamond[1],Al Ga N[2],Mg Zn O[3],and Ga_2O_3[4-11].Among these materials,Ga_2O_3has a direct band gap(~4.9 e V)just falling in solarblind spectral range,which makes Ga_2O_3a desirable candidate for solar-blind photodetection.Up to now,many kinds of Ga_2O_3PDs have been demonstrated including bulk[4,5],film[6-8]and nanostructures[9-11],as summarized in Table 1.From the summary,we can see although bulkShujuan Cui Zengxia Mei Yaonan Hou Muhua Sun Quansheng Chen Huili Liang Yonghui Zhang Xuedong Bai Xiaolong Du 2018Science China(Physics,Mechanics & Astronomy)2018,61,10:0
