1板块构造机制在显生宙初期发生转变显示文摘虽然目前对于板块构造何时成为主要构造机制存在争议,但是研究者普遍认为在古太古代已经完成转变。元古代时期,哥伦比亚超大陆向罗迪尼亚超大陆的转换,并未发生超大陆的完全裂解和聚合,而是岩石圈和环境的相对稳定期。相比之下,成冰期至今则发育有大量的被动大陆边缘,以及在425~225 Ma期间大幅增加的裂谷和大陆岛弧长度,表明存在与潘吉亚超大陆形成密切相关的激烈板块构造活动。袁超(编译) Brown M Kirkland C L Johnson T E 2020矿物岩石地球化学通报2020,39,4:9

3慢性淋巴细胞白血病诊治指南显示文摘流行病学 慢性淋巴细胞白血病(CLL)在西方国家很常见,占65岁以上白血病患者的65%.中位发病年龄65~70岁.30岁以下极为罕见,但20%~30%病例于55岁前发病,年发病率约3/10万.欧洲、澳大利亚、北美白人以及黑人的发病率是印度、中国及日本的20~30倍.男女之比约2:1.无确凿证据显示,接触化学物质和射线、饮食、吸烟、病毒感染和自身免疫性疾病为本病的高危因素,但患者一级和二级亲属淋巴系统恶性肿瘤发病率增高.许多家族尚存在患者后代发病年龄更早、病情更重的现象.经治和未治患者第二肿瘤发病率增高.Oscier D Fegan C Hillman P Illide T Johnson S Maguir P Matutes M Milligan D 孙蕾 高举 2005国外医学(输血及血液学分册)2005,28,1:6
4Artificial intelligence in gastroenterology: A state-of-the-art review显示文摘The development of artificial intelligence(AI)has increased dramatically in the last 20 years,with clinical applications progressively being explored for most of the medical specialties.The field of gastroenterology and hepatology,substantially reliant on vast amounts of imaging studies,is not an exception.The clinical applications of AI systems in this field include the identification of premalignant or malignant lesions(e.g.,identification of dysplasia or esophageal adenocarcinoma in Barrett’s esophagus,pancreatic malignancies),detection of lesions(e.g.,polyp identification and classification,small-bowel bleeding lesion on capsule endoscopy,pancreatic cystic lesions),development of objective scoring systems for risk stratification,predicting disease prognosis or treatment response[e.g.,determining survival in patients post-resection of hepatocellular carcinoma),determining which patients with inflammatory bowel disease(IBD)will benefit from biologic therapy],or evaluation of metrics such as bowel preparation score or quality of endoscopic examination.The objective of this comprehensive review is to analyze the available AI-related studies pertaining to the entirety of the gastrointestinal tract,including the upper,middle and lower tracts;IBD;the hepatobiliary system;and the pancreas,discussing the findings and clinical applications,as well as outlining the current limitations and future directions in this field.Paul T Kröner Megan ML Engels Benjamin S Glicksberg Kipp W Johnson Obaie Mzaik Jeanin E van Hooft Michael B Wallace Hashem B El-Serag Chayakrit Krittanawong 2021World Journal of Gastroenterology2021,27,40:6
5Ammonia-oxidizing archaea and bacteria are structured by geography in biological soil crusts across North American arid lands显示文摘Introduction:Biological soil crusts(BSCs)can dominate surface cover in dry lands worldwide,playing an integral role in arid land biogeochemistry,particularly in N fertilization through fixation and cycling.Nitrification is a characteristic and universal N transformation in BSCs that becomes important for the export of N beyond the microscopic bounds of the crust itself.The contribution of ammonia-oxidizing bacteria(AOB)in BSCs has been shown,but the role and extent of the recently discovered ammonia-oxidizing archaea(AOA)have not.Methods:We sampled various types of crusts in four desert regions across the western United States and characterized the composition and size of ammonia-oxidizing communities using clone libraries and quantitative PCR targeting the amoA gene,which codes for the ammonia monooxygenase enzyme,universally present in ammonia-oxidizing microbes.Results:All archaeal amoA sequences retrieved from BSCs belonged to the Thaumarchaeota(Nitrososphaera associated Group I.1b).Sequences from the Sonoran Desert,Colorado Plateau,and Great Basin were indistinguishable from each other but distinct from those of the Chihuahuan Desert.Based on amoA gene abundances,archaeal and bacterial ammonia oxidizers were ubiquitous in our survey,but the ratios of archaeal to bacterial ammonia oxidizers shifted from bacterially dominated in northern,cooler deserts to archaeally dominated in southern,warmer deserts.Conclusions:Archaea are shown to be potentially important biogeochemical agents of biological soil crust N cycling.Conditions associated with different types of BSCs and biogeographical factors reveal a niche differentiation between AOA and AOB,possibly driven by temperature.Yevgeniy Marusenko Scott T Bates Ian Anderson Shannon L Johnson Tanya Soule Ferran Garcia-Pichel 2013Ecological Processes2013,2,1:4
6Prevalence of unsuspected thyroid nodules in adults on contrast enhanced 16-and 64-MDCT of the chest显示文摘AIM: To determine the prevalence of unsuspected thyroid nodules on contrast enhanced 16and 64-modified discrete cosine transform (MDCT) of the chest, in a population of adult outpatients imaged for indications other than thyroid disease. METHODS: This retrospective study involved review of intravascular contrast-enhanced MDCT scans of the chest from 3077 consecutive adult outpatients, to identify unsuspected thyroid nodules. Exclusion criteria included history of thyroid cancer, known thyroid nodules or thyroid disease and risk factors for thyroid cancer, as evidenced by their medical records. One of 9 radiologists recorded number of nodules, location and bidirectional measurement of largest nodule, as well as amount of thyroid visualized on the chest computed tomography (CT). Presence of nodule was correlated with age, gender, race and percentage of thyroid imaged. RESULTS: A total of 2510 (2510/3077 or 81.6%) study subjects were included in the data analysis; among them,one or more nodules were identified in 629 subjects (629/2510 or 25.1%), with 242 (242/629 or 38.5%) having multiple nodules. Patients with nodule(s) were significantly older than those without (64 ± 13 years vs 58 ± 14 years, P < 0.0001), and female gender was associated with presence of nodule(s) (373/1222 or 30.5% vs 256/1288 or 19.9%, P < 0.0001). Women were also more likely having multiple nodules (167/373 or 44.8%) compared to men (75/256 or 29.3%, P < 0.0001). The majority of nodules (427/629 or 67.9%) were less than 1 cm. CONCLUSION: This retrospective review revealed a prevalence of 25.1% for unsuspected thyroid nodules on contrast-enhanced chest CT.Sameer Ahmed Pamela T Johnson Karen M Horton Atif Zaheer Saline Tsai Elliot K Fishman 2012World Journal of Radiology2012,4,7:4

12尿酸是正常高值血压发展为高血压的一个重要危险标志物显示文摘正常高值血压常发展为高血压,是一个与心血管病和脑卒中高死亡率和高发病率相关的事件。然而,正常高值血压发展成高血压的危险因素仍不清楚。研究者采用年龄(52.1±11.0)岁日本成年高血压患者3584例(2081例为男性)的资料进行前瞻性群体研究,研究对象在2004年被发现处于正常高值血压阶段,并在2009年重新进行检查。黄洁 叶鹏 Kuwabara M Hisatome I Niwa K Hara S Roncal-Jimenez CA Bjornstad P Nakagawa T Andres-Hernando A Sato Y Jensen T Garcia G Rodriguez-Iturbe B Ohno M Lanaspa MA Johnson RJ 2017中华高血压杂志2017,25,12:2
13一种基于计算听觉场景分析的语音增强算法显示文摘选取ETSI语音增强系统作为研究对象.该系统使用传统维纳滤波方法,在信噪比较高时降噪性能优秀,但在信噪比较低的情况下,降噪能力弱,对于脉冲噪声无较好抑制.而模拟人耳听觉特性的计算听觉场景分析技术能够比较好地弥补这一缺陷.故在ETSI算法的基础上,结合计算听觉场景分析技术,提出一种新的算法,将维纳滤波器参数估计由原本的Mel域变换到Gammatone域,并进一步利用理想率掩蔽估计对带噪信号进行信噪分离,抑制脉冲噪声.该算法在TIMIT语音库上进行了实验,结果证明,与原算法相比,提出的新算法使听觉质量在低信噪比下提升较大,脉冲噪声抑制亦明显.在低信噪比的情况下,后端语音识别系统的识别率得到提升.张卫强 郭璁 张乔 康健 何亮 刘加 Johnson Michael T 2015天津大学学报(自然科学与工程技术版)2015,48,8:2

15Spectral reflectance response to nitrogen fertilization in field grown corn显示文摘This study was carried out to analyze the spectral reflectance response of different nitrogen levels for corn crops.Four different nitrogen treatments of 0%,80%,100%and 120%BMP(best management practice)were studied.Principal component analysis-loading(PCA-loading)was used to identify the effective wavelengths.Partial least squares(PLS)and multiple linear regression(MLR)models were built to predict different nitrogen values.Vegetation indices(VIs)were calculated and then used to build more prediction models.Both full and selected wavelengths-based models showed similar prediction trends.The overall PLS model obtained the coefficient of determination(R^(2))of 0.6535 with a root mean square error(RMSE)of 0.2681 in the prediction set.The selected wavelengths for overall MLR model obtained the R^(2) of 0.6735 and RMSE of 0.3457 in the prediction set.The results showed that the wavelengths in visible and near infrared region(350-1000 nm)performed better than the two either spectral regions(1001-1350/1425-1800 nm and 2000-2400 nm).For each data set,the wavelengths around 555 nm and 730 nm were identified to be the most important to predict nitrogen rates.The vogelmann red edge index 2(VOG 2)performed the best among all VIs.It demonstrated that spectral reflectance has the potential to be used for analyzing nitrogen response in corn.Chuanqi Xie Ce Yang Alexander Hummel Jr Gregg A Johnson Forrest T Izuno 2018International Journal of Agricultural and Biological Engineering2018,11,4:2
