1Chaotic laser synchronization and its application in optical fiber secure communication显示文摘In this paper, optical fiber chaotic secure communication is proposed by coupling chaotic laser synchronous system with optical fiber propagation channel. Feedback synchronous system of chaotic semiconductor lasers is presented and synchronous error and decoding formulae are demonstrated. Synchronization between two chaotic laser systems with distributed feedback semiconductor lasers at wavelength of 1.31 μm is simulatively achieved with almost zero synchronous error. Parameter mismatch, synchronous transient response and noise effect on the system are studied. Robustness of synchronization and anti-perturbation can increase by increasing the feedback coefficient of the system. Influence of group-velocity-dispersion and self-phase modulation of optical fiber on chaotic laser signal and synchronization are analyzed, and it is found that group-velocity-dispersion affects pulse shape, synchronization and decodin gand limits optical fiber propagation distances, and self-phase modulation does not affect pulse shape, while its product of nonlinear phase shift can affect synchronization and decoding, and restrict propagation distances of optical fiber chaotic communication system and hence the maximum optical power formula is educed. Injecting parameter modulation and amplitude modulation are numerically simulated in long-haul optical fiber secure communication systems.YAN Senlin CHI Zeying CHEN Wenjian Schoof of Electronic Engineering and Photoelectronic Technology, Nanjing University of Science and Technology, Nanjing 210094, China 2004Science in China(Series F)2004,47,3:10
2Establishment and analysis of global gridded Tm-Ts relationship model显示文摘In ground-based GPS meteorology, Tm is a key parameter to calculate the conversion factor that can convert the zenith wet delay(ZWD) to precipitable water vapor(PWV). It is generally acknowledged that Tm is in an approximate linear relationship with surface temperature Ts, and the relationship presents regional variation. This paper employed sliding average method to calculate correlation coefficients and linear regression coefficients between Tm and Ts at every 2°× 2.5° grid point using Ts data from European Centre for Medium-Range Weather Forecasts(ECMWF) and Tm data from 'GGOS Atmosphere', yielding the grid and bilinear interpolation-based Tm Grid model. Tested by Tm and Ts grid data, Constellation Observation System of Meteorology, Ionosphere, and Climate(COSMIC) data and radiosonde data, the Tm Grid model shows a higher accuracy relative to the Bevis Tm-Ts relationship which is widely used nowadays. The Tm Grid model will be of certain practical value in high-precision PWV calculation.Zeying Lan Bao Zhang Yichao Geng 2016Geodesy and Geodynamics2016,7,2:7
3A global assessment of recent trends in gastrointestinal cancer and lifestyle-associated risk factors显示文摘Background:Gastrointestinal(GI)cancers were responsible for 26.3%of cancer cases and 35.4%of deaths worldwide in 2018.This study aimed to analyze the global incidence,mortality,prevalence,and contributing risk factors of the 6 major GI cancer entities[esophageal cancer(EC),gastric cancer(GC),liver cancer(LC),pancreatic cancer(PC),colon cancer,and rectal cancer].Methods:Using the Global Cancer Observatory and the Global Health Observatory databases,we reviewed the current GI cancer incidence,prevalence,and mortality,analyzed the association of GI cancer prevalence with national human development indices(HDIs),identified the contributing risk factors,and estimated developing age-and sex-specific trends in incidence and mortality.Results:In 2020,the trend in age-standardized rate of incidence of GI cancers closely mirrored that of mortality,with the highest rates of LC,EC,and GC in Asia and of colorectal cancer(CRC)and PC mainly in Europe.Incidence and mortality were positively,but the mortality-to-incidence ratio(MIR)was inversely correlated with the national HDI levels.High MIRs in developing countries likely reflected the lack of preventive strategies and effective treatments.GI cancer prevalence was highest in Europe and was also positively correlated with HDIs and lifestyle-associated risk factors,such as alcohol consumption,smoking,obesity,insufficient physical activity,and high blood cholesterol level,but negatively correlated with hypertension and diabetes.Incidences of EC were consistently and those of GC mostly decreasing,whereas incidences of CRC were increasing in most countries/regions,especially in the younger populations.Incidences of LC and PC were also increasing in all age-gender populations except for younger males.Mortalities were decreasing for EC,GC,and CRC in most countries/regions, and age-specific trends were observed in PC and LC with adecrease in the younger but an increase in the older population.Conclusions: On the global scale, higher GI cancer burden was accompanied,for the most part, by factors associated with the so-called Western lifestylereflected by high and very high national HDI levels. In countries/regionswith very high HDI levels, patients survived longer, and increasing GI cancercases were observed with increasing national HDI levels. Optimizing GI cancer prevention and improving therapies, especially for patients with comorbidmetabolic diseases, are thus urgently recommended.Lili Lu Christina S.Mullins Clemens Schafmayer Sebastian Zeißig Michael Linnebacher 2021Cancer Communications2021,41,11:6
4Description and Evaluation Approach for Uncertainty of RS Images Classi- fication显示文摘与关于遥感图象的分类质量的研究的开发,研究人员们认为不确定性是影响分类质量的主要因素。这研究提出一条途径到不确定性表示,它从二个方面被开发:形式化的描述和全面评估。首先,我们用模糊监视途径完成分类,作为对分类不确定性的形式化的描述拿它。然后,我们为分类不确定性评估介绍一个混合的熵模型,它能满足几不确定性的全面思考的要求,当与对每个象素的错误率的不同贡献的完整的考虑从象素规模构造评估索引时。最后,一个应用程序例子将被学习检验新方法。结果证明评估结果充分反映分类质量,当与常规评估相比从单一的不确定性和范畴构造模型的方法可伸缩时。LAN Zeying LIU Yanfang TANG Xiangyun LIU Yang 2009Geo-Spatial Information Science2009,12,1:3
5Instrumental detection of cystic duct stones during laparoscopic cholecystectomy显示文摘Residual cystic duct stones (CDSs) after cholecystectomy have been recognized as a cause of post cholecystectomy pain. This study was undertaken to determine the incidence of CDSs during laparoscopic cholecystectomy(LC). A cohort of 330 consecutive patients (80 males and 250females) undergoing LC between November 2006 and May2010 was studied. Their age ranged between 16 and 88 years(median 50, IQR: 36.62). The data were prospectively collected of preoperative liver function tests, imaging, the presence of intraoperative CDSs, and common bile duct stones at on-table cholangiogram. CDSs were detected intraoperatively in 64 of the 330 patients (19%). Ultrasound failed to detect CDSs in any of these cases. Deranged liver function tests were noted in 73% of the patients with CDSs and in 57% without CDSs Common bile duct stones were detected in 9% (29) of the 330patients. CDSs occur commonly at routine cholecystectomy, and preoperative investigations are not helpful in their diagnosis As CDSs may lead to postoperative morbidity, they should be actively sought out during surgery if present.Amir Kambal Tomos Richards Harsha Jayamanne Zeyed Sallami Ashraf Rasheed Taha Lazim 2014Hepatobiliary & Pancreatic Diseases International2014,13,2:3

7Reducing relapse and accelerating osteogenesis in rapid maxillary expansion using an injectable mesoporous bioactive glass/fibrin glue composite hydrogel显示文摘Rapid maxillary expansion(RME),as a common treatment for craniomaxillofacial deformity,faces the challenge of high relapse rates and unsatisfactory therapeutic effects.In this study,a standardized Sprague-Dawley(SD)rat RME model was first established with a modified expander as well as retainer design and optimized anterior maxillary expanding force of 100 g which exerted the most synchronized mobility of mid-palatal suture and incisors.Via the standardized model,the high relapse rate was proven to be attributed to insufficient osteogenesis in expanded suture,requiring long-term retainer wearing in clinical situations.To reduce the relapse rate,mesoporous bioactive glass/fibrin glue(MBG/FG)composite hydrogels were developed for an in situ minimal invasive injection that enhance osteogenesis in the expanded palate.The component of 1 wt%MBG was adopted for enhanced mechanical strength,matched degradation rate and ion dissolution,excellent in vitro biocompatibility and osteoinductivity.Effects of 1%MBG/FG composite hydrogel on osteogenesis in expanded mid-palatal sutures with/without retention were evaluated in the standardized model.The results demonstrated that injection of 1%MBG/FG composite hydrogel significantly promoted bone formation within the expanded mid-palatal suture,inhibited osteoclastogenesis and benefited the balance of bone remodeling towards osteogenesis.Combination of retainer and injectable biomaterial was demonstrated as a promising treatment to reduce relapse rate and enhance osteogenesis after RME.The model establishment and the composite hydrogel development in this article might provide new insight to other craniomaxillofacial deformity treatment and design of bone-repairing biomaterials with higher regenerative efficiency.Hanjiang Zhao Xiangyu Wang Anting Jin Minjiao Wang Zeying Wang Xingtai Huang Jiewen Dai Xudong Wang Dan Lin Steve GF.Shen 2022Bioactive Materials2022,7,12:2
8高温质子交换膜燃料电池催化层孔尺度模拟显示文摘为了研究磷酸在高温质子交换膜燃料电池催化层中再分布对电极性能的影响,使用聚焦离子束电子扫描显微镜对自制的扩散电极成像,重构得到了三维的催化层几何模型;采用多弛豫时间格子玻尔兹曼模型对磷酸在催化层的迁移行为进行仿真,模拟得到递减型和准均匀型2种不同的磷酸分布形式;采用孔尺度模型求解不同条件下的电极传输性质。结果表明在磷酸含量较低时,准均匀型的磷酸分布具有稍优的电化学活性表面积和稍差的氧气和水蒸气有效扩散系数;在磷酸含量较高时,2种分布的电化学活性表面积相似,但是准均匀型分布具有更好的氧气和水蒸气有效扩散系数。段康俊 Roswitha ZEIS 隋邦傑 2022重庆大学学报2022,45,8:2
