1专用气候数据空间插值软件ANUSPLIN及其应用显示文摘空间化的气候数据作为环境因子参数是区域气候模型和地学模型的基础,而插值软件是实现气候观测点数据空间化的工具。ANUSPLIN基于薄盘样条函数理论,引入多个影响因子作为协变量进行气象要素空间插值,大大提高插值精度,且能同时进行多个表面的空间插值,对时间序列的气象要素更加适合。刘志红 Tim R. McVicar Van Niel T. G 杨勤科 李锐 2008气象2008,34,2:180
2Retrospective study on mixed neuroendocrine non-neuroendocrine neoplasms from five European centres显示文摘BACKGROUND Mixed neuroendocrine non-neuroendocrine neoplasm(MiNEN)is a rare diagnosis,mainly encountered in the gastro-entero-pancreatic tract.There is limited knowledge of its epidemiology,prognosis and biology,and the best management for affected patients is still to be defined.AIM To investigate clinical-pathological characteristics,treatment modalities and survival outcomes of a retrospective cohort of patients with a diagnosis of MiNEN.METHODS Consecutive patients with a histologically proven diagnosis of MiNEN were identified at 5 European centres.Patient data were retrospectively collected from medical records.Pathological samples were reviewed to ascertain compliance with the 2017 World Health Organisation definition of MiNEN.Tumour responses to systemic treatment were assessed according to the Response Evaluation Criteria in Solid Tumours 1.1.Kaplan-Meier analysis was applied to estimate survival outcomes.Associations between clinical-pathological characteristics and survival outcomes were explored using Log-rank test for equality of survivors functions(univariate)and Cox-regression analysis(multivariable).RESULTS Sixty-nine consecutive patients identified;Median age at diagnosis:64 years.Males:63.8%.Localised disease(curable):53.6%.Commonest sites of origin:colon-rectum(43.5%)and oesophagus/oesophagogastric junction(15.9%).The neuroendocrine component was;predominant in 58.6%,poorly differentiated in 86.3%,and large cell in 81.25%,of cases analysed.Most distant metastases analysed(73.4%)were occupied only by a poorly differentiated neuroendocrine component.Ninety-four percent of patients with localised disease underwent curative surgery;53%also received perioperative treatment,most often in line with protocols for adenocarcinomas from the same sites of origin.Chemotherapy was offered to most patients(68.1%)with advanced disease,and followed protocols for pure neuroendocrine carcinomas or adenocarcinomas in equal proportion.In localised cases,median recurrence free survival(RFS);14.0 months(95%CI:9.2-24.4),and median overall survival(OS):28.6 months(95%CI:18.3-41.1).On univariate analysis,receipt of perioperative treatment(vs surgery alone)did not improve RFS(P=0.375),or OS(P=0.240).In advanced cases,median progression free survival(PFS);5.6 months(95%CI:4.4-7.4),and median OS;9.0 months(95%CI:5.2-13.4).On univariate analysis,receipt of palliative active treatment(vs best supportive care)prolonged PFS and OS(both,P<0.001).CONCLUSION MiNEN is most commonly driven by a poorly differentiated neuroendocrine component,and has poor prognosis.Advances in its biological understanding are needed to identify effective treatments and improve patient outcomes.Melissa Frizziero Xin Wang Bipasha Chakrabarty Alexa Childs Tu V Luong Thomas Walter Mohid S Khan Meleri Morgan Adam Christian Mona Elshafie Tahir Shah Annamaria Minicozzi Wasat Mansoor Tim Meyer Angela Lamarca Richard A Hubner Juan W Valle Mairéad G McNamara 2019World Journal of Gastroenterology2019,25,39:13

4Machine-learned multi-system surrogate models for materials prediction显示文摘Surrogate machine-learning models are transforming computational materials science by predicting properties of materials with the accuracy of ab initio methods at a fraction of the computational cost.We demonstrate surrogate models that simultaneously interpolate energies of different materials on a dataset of 10 binary alloys(AgCu,AlFe,AlMg,AlNi,AlTi,CoNi,CuFe,CuNi,FeV,and NbNi)with 10 different species and all possible fcc,bcc,and hcp structures up to eight atoms in the unit cell,15,950 structures in total.We find that the deviation of prediction errors when increasing the number of simultaneously modeled alloys is<1 meV/atom.Several state-of-the-art materials representations and learning algorithms were found to qualitatively agree on the prediction errors of formation enthalpy with relative errors of<2.5% for all systems.Chandramouli Nyshadham Matthias Rupp Brayden Bekker Alexander V.Shapeev Tim Mueller Conrad W.Rosenbrock Gábor Csányi David W.Wingate Gus L.W.Hart 2019npj Computational Materials2019,,1:8
5Oxygen radical formation does not have an impact in the treatment of severe acute experimental pancreatitis using free cellular hemoglobin显示文摘瞄准:Microcirculatory 机能障碍和免费的氧激进分子是在严重尖锐胰腺炎的致病的重要因素。另外的氧交货可能每氧化提高类脂化合物,但是可以也改进胰腺的微循环。这研究在严重尖锐胰腺炎的一个啮齿类动物模型在氧激进分子和微循环的形成上估计免费细胞的牛的血红素的效果。方法:在尖锐胰腺炎 Wistar 老鼠的正式就职以后的十五分钟收到了任何一个 0.8 mL 牛的血红素(HBOC-200 ) , hydroxyethyl 淀粉(HES ) 或保证血量正常替换的生理盐水的 2.4 mL。在检查的 6 h 以后,胰每氧化产品 malondialdehyde (MDA ) 为类脂化合物的间接测量被切除并且很快处理了并且在胰腺的织物减少了谷胱甘肽(GSH ) 。结果:HBOC-200 的单个申请改进了胰腺的微循环并且显著地减少了组织病理学说的织物损坏。MDA 的织物集中没在这些组之间不同。另外,在 GSH 层次的差别都没被检测。结论:不过 HBOC-200 和 HES 的单个申请改进胰腺的微循环,在类脂化合物的没有差别每氧化,产品被检测。另外的氧供应(HBOC-200 ) 的有益的效果不每氧化导致提高的类脂化合物。Helge Kleinhans Oliver Mann Paulus G Schurr Jussuf T Kaifi Bente Hansen Jakob R Izbicki Tim Strate 2006World Journal of Gastroenterology2006,12,18:6
6澳大利亚人乳头状瘤病毒疫苗计划实施5年对年轻人群生殖器疣患病情况的影响:国家调查数据分析显示文摘目的评估2007年中开始的澳大利亚人乳头状瘤病毒(HPV)疫苗计划对生殖器疣患病情况的影响。设计国家调查数据趋势分析。数据来源数据收集于2004--2011年度澳大利亚8所性健康服务机构;其中2所最大的临床中心收集了自我报告的本中心2009年度HPV疫苗现状。研究对象2004--2011年度首次就诊的85770名澳大利亚出生的国民;其中7686(9.0%)名患生殖器疣。主要结局测量比较前疫苗时期(2004—2007年中)和疫苗时期(2007年中-2001年末)不同人群生殖器疣新发病率变化趋势。结果疫苗时期21岁以下和21~30岁女性诊断患有生殖器疣的比例明显下降,发病率分别从2007年度的11.5%和11.3%下降至2011年度的0.85%和3.1%,P均〈0.001。在30岁以上的女性中未发现发病率的明显下降。在21岁以下和21~30岁异性恋男性人群中疫苗时期生殖器疣的发病率较前疫苗时期明显下降,分别由2007年度12.1%和18.2%下降至2011年度2.2%和8.9%,P均〈0.001。30岁以上的异性恋男性人群中发病率无明显下降。2011年235名21岁以下女性在使用HPV疫苗后无新发生殖器疣病例。结论年轻女性生殖器疣发病率的显著下降和2011年度部分年轻女性使用疫苗后的零发病率,说明HPV疫苗获得实验室外的良好功效。异性恋男性生殖器疣发病率的显著下降可能是由于群体免疫所致。Hammad Ali,lecturer Basil Donovan, professor HandanWand,senior lecturer Tim R H Read, sexual health physician David G Regan,senior lecturer Andrew E Grulich, professor Christopher K FaMey, professor Rebecca J Guy, associate professor 尹婕(译) 潘凌亚(校) 2013英国医学杂志中文版2013,16,4:4

16Coherent interaction of atoms with a beam of light confined in a light cage显示文摘Controlling coherent interaction between optical fields and quantum systems in scalable,integrated platforms is essential for quantum technologies.Miniaturised,warm alkali-vapour cells integrated with on-chip photonic devices represent an attractive system,in particular for delay or storage of a single-photon quantum state.Hollow-core fibres or planar waveguides are widely used to confine light over long distances enhancing light-matter interaction in atomic-vapour cells.However,they suffer from inefficient filling times,enhanced dephasing for atoms near the surfaces,and limited light-matter overlap.We report here on the observation of modified electromagnetically induced transparency for a non-diffractive beam of light in an on-chip,laterally-accessible hollow-core light cage.Atomic layer deposition of an alumina nanofilm onto the light-cage structure was utilised to precisely tune the high-transmission spectral region of the light-cage mode to the operation wavelength of the atomic transition,while additionally protecting the polymer against the corrosive alkali vapour.The experiments show strong,coherent light-matter coupling over lengths substantially exceeding the Rayleigh range.Additionally,the stable non-degrading performance and extreme versatility of the light cage provide an excellent basis for a manifold of quantum-storage and quantumnonlinear applications,highlighting it as a compelling candidate for all-on-chip,integrable,low-cost,vapour-based photon delay.Flavie Davidson-Marquis Julian Gargiulo Esteban Gómez-López Bumjoon Jang Tim Kroh Chris Müller Mario Ziegler Stefan A.Maier Harald Kübler Markus A.Schmidt Oliver Benson 2021Light(Science & Applications)2021,10,7:1
