1Broadband diffusion of terahertz waves by multi-bit coding metasurfaces显示文摘The terahertz region is a special region of the electromagnetic spectrum that incorporates the advantages of both microwaves and infrared light waves.In the past decade,metamaterials with effective medium parameters or gradient phases have been studied to control terahertz waves and realize functional devices.Here,we present a new approach to manipulate terahertz waves by using coding metasurfaces that are composed of digital coding elements.We propose a general coding unit based on a Minkowski closed-loop particle that is capable of generating 1-bit coding(with two phase states of 0 and 180°),2-bit coding(with four phase states of 0,90°,180°,and 270°),and multi-bit coding elements in the terahertz frequencies by using different geometric scales.We show that multi-bit coding metasurfaces have strong abilities to control terahertz waves by designing-specific coding sequences.As an application,we demonstrate a new scattering strategy of terahertz waves—broadband and wide-angle diffusion—using a 2-bit coding metasurface with a special coding design and verify it by both numerical simulations and experiments.The presented method opens a new route to reducing the scattering of terahertz waves.Li-Hua Gao Qiang Cheng Jing Yang Shao-Jie Ma Jie Zhao Shuo Liu Hai-Bing Chen Qiong He Wei-Xiang Jiang Hui-Feng Ma Qi-Ye Wen Lan-Ju Liang Biao-Bing Jin Wei-Wei Liu Lei Zhou Jian-Quan Yao Pei-Heng Wu Tie-Jun Cui 2015Light(Science & Applications)2015,4,1:31
2Current concepts on the role of nitric oxide in portal hypertension显示文摘Portal hypertension(PHT) is defined as a pathological increase in portal venous pressure and frequently accompanies cirrhosis.Portal pressure can be increased by a rise in portal blood flow,an increase in vascular resistance,or the combination.In cirrhosis,the primary factor leading to PHT is an increase in intra-hepatic resistance to blood flow.Although much of this increase is a mechanical consequence of architectural disturbances,there is a dynamic and reversible component that represents up to a third of the increased vascular resistance in cirrhosis.Many vasoactive substances contribute to the development of PHT.Among these,nitric oxide(NO) is the key mediator that paradoxically regulates the sinusoidal(intra-hepatic) and systemic/splanchnic circulations.NO deficiency in the liver leads to increased intra-hepatic resistance while increased NO in the circulation contributes to the hyperdynamic systemic/splanchnic circulation.NO mediated-angiogenesis also plays a role in splanchnic vasodilation and collateral circulation formation.NO donors reduce PHT in animals models but the key clinical challenge is the development of an NO donor or drug delivery system that selectively targets the liver.Liang Shuo Hu Jacob George Jian Hua Wang 2013World Journal of Gastroenterology2013,19,11:18
3Trocar-site hernia after gynecological laparoscopic surgery: a 20-year, single-center experience显示文摘Background:Trocar-site hernia(TSH)is a serious complication after laparoscopic procedures.Although it is a rare entity,it have life-threatening consequences.This study aimed to retrospectively analyze the potential associated factors for TSH following gynecologic laparoscopy and summarize prevention strategies based on our experience.Methods:We searched for gynecological laparoscopic surgeries in the medical records system of Peking Union Medical College Hospital(PUMCH)from August 1998 to July 2018 and further sifted through the results for cases involving TSH.All included patients were divided into different groups according to patient characteristics,and the rate of TSH was compared among groups.Moreover,the detailed information of all patients with TSH was recorded and analyzed.Statistical analyses were performed with GraphPad Prism 6.Results:The approximate total rate of post-operative TSH among gynecologic laparoscopy procedures performed at PUMCH in the last 20 years was 0.016%(9/55,244).The rate of TSH was significant higher in elder patients(>60 years old;3/2686,0.112%)than in younger patients(<60 years old,6/52,558;0.011%,P=0.008).Moreover,the approximate rate of TSH was significantly higher after single-incision laparoscopic surgery(SILS,2/534,0.357%)than conventional laparoscopic surgery(7/54,710,0.013%,P=0.003).The average age of patients with TSH was 53.4 years(range,35.0-79.0 years).Two of the nine patients had late-onset TSH following SILS;the other seven had early-onset TSH following conventional laparoscopy.Five TSH cases occurred at right lateral port sites,and the remaining three occurred at the umbilical port site.All patients underwent repair surgery,and one required small bowel resection.Conclusion:Older age and SILS are potential associated factors for TSH development,while reducing excessive manipulation and improving suturing skills,especially at the umbilical trocar site following SILS and the right lateral trocar site,can avoid herniation.Ya-Pei Zhu Shuo Liang Lan Zhu Zhi-Jing Sun Jing-He Lang 2019Chinese Medical Journal2019,,22:16
4Haemoglobin,albumin,lymphocyte and platelet predicts postoperative survival in pancreatic cancer显示文摘BACKGROUND Systemic inflammation and nutrition status play an important role in cancer metastasis.The combined index of hemoglobin,albumin,lymphocyte,and platelet(HALP),consisting of haemoglobin,albumin,lymphocytes,and platelets,is considered as a novel marker to reflect both systemic inflammation and nutrition status.However,no studies have investigated the relationship between HALP and survival of patients with pancreatic cancer following radical resection.AIM To evaluate the prognostic value of preoperative HALP in pancreatic cancer patients.METHODS The preoperative serum levels of hemoglobin,albumin,lymphocyte counts,and platelet counts were routinely detected in 582 pancreatic adenocarcinoma patients who underwent radical resection.The relationship between postoperative survival and the preoperative level of HALP was investigated.RESULTS Low levels of HALP were significantly associated with lymph node metastasis(P=0.002),poor tumor differentiation(P=0.032),high TNM stage(P=0.008),female patients(P=0.005)and tumor location in the head of the pancreas(P<0.001).Low levels of HALP were associated with early recurrence[7.3 mo vs 16.3 mo,P<0.001 for recurrence-free survival(RFS)]and short survival[11.5 mo vs 23.6 mo,P<0.001 for overall survival(OS)]in patients with resected pancreatic adenocarcinoma.A low level of HALP was an independent risk factor for early recurrence and short survival irrespective of sex and tumor location.CONCLUSION Low levels of HALP may be a significant risk factor for RFS and OS in patients with resected pancreatic cancer.Shuai-Shuai Xu Shuo Li Hua-Xiang Xu Hao Li Chun-Tao Wu Wen-Quan Wang He-Li Gao Wang Jiang Wu-Hu Zhang Tian-Jiao Li Quan-Xing Ni Liang Liu Xian-Jun Yu 2020World Journal of Gastroenterology2020,26,8:14
5Impact of dissolved organic matter on the photolysis of the ionizable antibiotic norfloxacin显示文摘Norfloxacin(NOR), an ionizable antibiotic frequently used in the aquaculture industry, has aroused public concern due to its persistence, bacterial resistance, and environmental ubiquity.Therefore, we investigated the photolysis of different species of NOR and the impact of a ubiquitous component of natural water — dissolved organic matter(DOM), which has a special photochemical activity and normally acts as a sensitizer or inhibiter in the photolysis of diverse organics; furthermore, scavenging experiments combined with electron paramagnetic resonance(EPR) were performed to evaluate the transformation of NOR in water. The results demonstated that NOR underwent direct photolysis and self-sensitized photolysis via hydroxyl radical(U OH) and singlet oxygen(1O2) based on the scavenging experiments. In addition, DOM was found to influence the photolysis of different NOR species, and its impact was related to the concentration of DOM and type of NOR species. Photolysis of cationic NOR was photosensitized by DOM at low concentration, while zwitterionic and anionic NOR were photoinhibited by DOM, where quenching of U OH predominated according to EPR experiments, accompanied by possible participation of excited triplet-state NOR and1O2. Photo-intermediate identification of different NOR species in solutions with/without DOM indicated that NOR underwent different photodegradation pathways including dechlorination, cleavage of the piperazine side chain and photooxidation, and DOM had little impact on the distribution but influenced the concentration evolution of photolysis intermediates. The results implied that for accurate ecological risk assessment of emerging ionizable pollutants, the impact of DOM on the environmental photochemical behavior of all dissociated species should not be ignored.Chen Liang Huimin Zhao Minjie Deng Xie Quan Shuo Chen Hua Wang 2015Journal of Environmental Sciences2015,27,1:11
6Predictive Values of Postoperative and Dynamic Changes of Inflammation Indexes in Survival of Patients with Resected Colorectal Cancer显示文摘The aim of the present study was to evaluate the prognostic potential of postoperative scores of inflammation indexes and the dynamic changes of scores before and after tumor resection in colorectal cancer patients.The study included 516 colorectal cancer patients with primary colorectal tumor resection.Cox regression was applied to estimate the associations of postoperative and dynamic changes of inflammation indexes with progression-free survival and overall survival.As results,we found that higher postoperative neutrophil to lymphocyte ratio (NLR),neutrophil and monocyte to lymphocyte ratio (NMLR),platelet to lymphocyte ratio (PLR) and systemic immune inflammation index (SII)were associated with shorter progression-free survival.The increased NLR,NMLR,PLR,SII and C-reaction protein (CRP)to albumin (ALB) ratio (CAR)were associated with poor progression-free survival,with HRs (95% CIs)of 1.92 (1.27-2.90),1.46(1.11-2.09),2.10(1.34-3.30),1.81(1.22-2.70)and 1.65(1.03-2.67), respectively.Postoperative NMLR,SII,CAR,and their dynamic changes were also significantly correlated with overall survival,with the HRs (95% CIs)of 2.63(1.30-3.97), 2.44(1.43-4.17),2.74(1.31-5.74),2.08(1.21-3.60),1.97(1.12-3.45)and 2.55(1.21-5.38)respectively.In conclusion,postoperative inflammation indexes and their dynamic changes,particularly for NMLR,SII and CAR are promising prognostic predictors of CRC patients.Zi-quan ZHOU Shuo PANG Xing-chen YU Qi XUE Hong-yu JIANG Xin-jun LIANG Li LIU 2018Current Medical Science2018,38,5:10
7Numerical simulation of aerodynamic interaction for a tilt rotor aircraft in helicopter mode显示文摘A rotor CFD solver is developed for simulating the aerodynamic interaction phenomenon among rotor, wing and fuselage of a tilt rotor aircraft in its helicopter mode. The unsteady Navier–Stokes equations are discretized in inertial frame and embedded grid system is adopted for describing the relative motion among blades and nacelle/wing/fuselage. A combination of multi-layer embedded grid and ‘‘extended hole fringe' technique is complemented in original grid system to tackle grid assembly difficulties arising from the narrow space among different aerodynamic components, and to improve the interpolation precision by decreasing the cell volume discrepancy among different grid blocks. An overall donor cell searching and automatic hole cutting technique is used for grid assembly, and the solution processes are speeded up by introduction of Open MP parallel method. Based on this solver, flow fields and aerodynamics of a tilt rotor aircraft in hover are simulated with several rotor collective angles, and the corresponding states of an isolated rotor and rotor/wing/fuselage model are also computed to obtain reference solution.Aerodynamic interference influences among the rotor and wing/fuselage/nacelle are analyzed,and some meaningful conclusions are drawn.Ye Liang Zhang Ying Yang Shuo Zhu Xinglin Dong Jun 2016Chinese Journal of Aeronautics2016,29,4:10
8Review of Remotely Sensed Imagery Classification Patterns Based on Object-oriented Image Analysis显示文摘With the wide use of high-resolution remotely sensed imagery, the object-oriented remotely sensed informa- tion classification pattern has been intensively studied. Starting with the definition of object-oriented remotely sensed information classification pattern and a literature review of related research progress, this paper sums up 4 developing phases of object-oriented classification pattern during the past 20 years. Then, we discuss the three aspects of method- ology in detail, namely remotely sensed imagery segmentation, feature analysis and feature selection, and classification rule generation, through comparing them with remotely sensed information classification method based on per-pixel. At last, this paper presents several points that need to be paid attention to in the future studies on object-oriented RS in- formation classification pattern: 1) developing robust and highly effective image segmentation algorithm for multi-spectral RS imagery; 2) improving the feature-set including edge, spatial-adjacent and temporal characteristics; 3) discussing the classification rule generation classifier based on the decision tree; 4) presenting evaluation methods for classification result by object-oriented classification pattern.LIU Yongxue LI Manchun MAO Liang XU Feifei HUANG Shuo 2006Chinese Geographical Science2006,16,3:9
9Numerical study on flow fields and aerodynamics of tilt rotor aircraft in conversion mode based on embedded grid and actuator model显示文摘A method combining rotor actuator disk model and embedded grid technique is presented in this paper, aimed at predicting the flow fields and aerodynamic characteristics of tilt rotor aircraft in conversion mode more efficiently and effectively. In this method, rotor's influence is considered in terms of the momentum it impacts to the fluid around it; transformation matrixes among different coordinate systems are deduced to extend actuator method's utility to conversion mode flow fields' calculation. Meanwhile, an embedded grid system is designed, in which grids generated around fuselage and actuator disk are regarded as background grid and minor grid respectively, and a new method is presented for ‘donor searching' and ‘hole cutting' during grid assembling. Based on the above methods, flow fields of tilt rotor aircraft in conversion mode are simulated, with threedimensional Navier–Stokes equations discretized by a second-order upwind finite-volume scheme and an implicit lower–upper symmetric Gauss–Seidel(LU-SGS) time-stepping scheme. Numerical results demonstrate that the proposed CFD method is very effective in simulating the conversion mode flow fields of tilt rotor aircraft.Zhang Ying Ye Liang Yang Shuo 2015Chinese Journal of Aeronautics2015,28,1:8

11The expression and binding properties of the rice WRKY68 protein in the Xa21-mediated resistance response to Xanthomonas oryzae pv. Oryzae显示文摘Plant WRKY transcription factors are involved in various physiological processes, including biotic and abiotic stress responses, as well as developmental processes. In this study, the expression patterns of the WRKY68 protein during interactions between rice 4021 containing the bacterial blight resistance gene Xa21 and Xanthomonas oryzae pv. oryzae(Xoo) were investigated. A possible modified form of the WRKY68 protein appeared in the Xa21-mediated disease resistance response, and its expression levels were similar in compatible and incompatible responses, but differed significantly from that of the mock control treatment, suggesting that WRKY68 may be involved in the bacterial blight response in rice. To further understand WRKY68's roles in the resistance signaling pathway, WRKY68 recombinant protein was expressed in Escherichia coli and a microscale thermophoresis analysis was performed to investigate the interactions between WRKY68 and cis-elements in crucial pathogenesis-related(PR) genes. The results showed that the WRKY68 protein binds to W-boxes in the PR1 b promoter region, with an apparent dissociation constant of 25 nmol L–1, while the binding between WRKY68 and PR10 a was W-box independent. The results suggested that a possible modified form of the WRKY68 protein was induced during the interaction between rice and Xoo, which then regulated the activity of the downstream PR genes by binding with the W-boxes in the PR1 b gene's promoter region. Moreover, the constitutive transcription of the WRKY68 gene in dozens of rice tissues and the expression of the WRKY68 protein in leaves during all growth stages suggests that WRKY68 plays important roles in rice during normal growth processes.YANG Shuo ZHOU Liang MIAO Liu-yang SHI Jia-nan SUN Cai-qiang FAN Wei LAN Jin-ping CHEN Hao LIU Li-juan DOU Shi-juan LIU Guo-zhen LI Li-yun 2016Journal of Integrative Agriculture2016,15,11:6
12Kinetics of Oxidation Reaction for Magnetite Pellets显示文摘An experiment for the oxidation process of single magnetite pellet and theoretical analysis based on modified unreacted core shrinking(MUCS)model were carried out,and the controlling mechanisms of the initial and developing reactions were examined,respectively.From the study of the initial reaction,it was found that the chemical reaction of surface is the controlling step of the overall reaction when the temperature is up to about 750K,while the mass transfer through the gaseous boundary layer dominates the reaction rate when the temperature is above 750K.As the reaction developing within the pellet,the mass transfer through the produced layer becomes the controlling step.In addition,the effects of reaction conditions(such as oxygen concentration,temperature)on the fractional oxidation of magnetite pellet were determined.LIANG Ru-quan YANG Shuo YAN Fu-sheng HE Ji-cheng 2013Journal of Iron and Steel Research(International)2013,20,9:6

18Whole Genome Analyses of Chinese Population and De Novo Assembly of A Northern Han Genome显示文摘To unravel the genetic mechanisms of disease and physiological traits,it requires comprehensive sequencing analysis of large sample size in Chinese populations.Here,we report the primary results of the Chinese Academy of Sciences Precision Medicine Initiative(CASPMI)project launched by the Chinese Academy of Sciences,including the de novo assembly of a northern Han reference genome(NH1.0)and whole genome analyses of 597 healthy people coming from most areas in China.Given the two existing reference genomes for Han Chinese(YH and HX1)were both from the south,we constructed NH1.0,a new reference genome from a northern individual,by combining the sequencing strategies of PacBio,10×Genomics,and Bionano mapping.Using this integrated approach,we obtained an N50 scaffold size of 46.63 Mb for the NH1.0 genome and performed a comparative genome analysis of NH1.0 with YH and HX1.In order to generate a genomic variation map of Chinese populations,we performed the whole-genome sequencing of 597 participants and identified 24.85 million(M)single nucleotide variants(SNVs),3.85 M small indels,and 106,382 structural variations.In the association analysis with collected phenotypes,we found that the T allele of rs1549293 in KAT8 significantly correlated with the waist circumference in northern Han males.Moreover,significant genetic diversity in MTHFR,TCN2,FADS1,and FADS2,which associate with circulating folate,vitamin B12,or lipid metabolism,was observed between northerners and southerners.Especially,for the homocysteine-increasing allele of rs1801133(MTHFR 677T),we hypothesize that there exists a “comfort”zone for a high frequency of 677T between latitudes of 35–45 degree North.Taken together,our results provide a high-quality northern Han reference genome and novel population-specific data sets of genetic variants for use in the personalized and precision medicine.Zhenglin Du Liang Ma Hongzhu Qu Wei Chen Bing Zhang Xi Lu Weibo Zhai Xin Sheng Yongqiao Sun Wenjie Li Meng Lei Qiuhui Qi Na Yuan Shuo Shi Jingyao Zeng Jinyue Wang Yadong Yang Qi Liu Yaqiang Hong Lili Dong Zhewen Zhang Dong Zou Yanqing Wang Shuhui Song Fan Liu Xiangdong Fang Hua Chen Xin Liu Jingfa Xiao Changqing Zeng 2019Genomics, Proteomics & Bioinformatics2019,17,3:4
