Relativistic Distorted-Wave Calculations of Electron Impact Excitation Cross Sections of Be-Like C2＋ Ions

引用

Chinese Physics Letters 2007年第3期24卷 691-694页

作者：蒋军董晨钟颉录有王建国颜君 stephan Fritzsche College of Physics and Electronic Engineering Northwest Normal University Lanzhou 730070 National Laboratory of Heavy-Ion Accelerator of Lanzhou Lanzhou 730000 Institute of Applied Physics and Computational Mathematic Beijing 100088 Institute für Physlk Universitat Kassel D-34132 Kassel Germany

A fully relativistic distorted-wave program is developed based on the Grasp92 and Ratip packages to calculate electron impact excitation （EIE） cross sections. As a first application of the program, the EIE cross sections of Be-like C^α＋ ions from the metastable 1s^22s2p^3 p to 1s^22p^2 ^3 p excitation and the inner-shell excitations are calculated systematically. Meanwhile, the correlation effects of target states are discussed. It is found that the correlation effects play an important role in the low energy EIE cross sections. An excellent agreement is found when the results are compared with previous calculations and recent measurements.

Monodisperse hollow silica spheres： An in-depth scattering analysis

Nano Research 2016年第5期9卷 1366-1376页

作者： Pia Ruckdeschel Martin Dulle Tobias Honold stephan Forster Matthias Karg Markus Retsch Physical Chemistry 1 - Polymer Systems University ofBayreuth Universitatsstr. 30 95447 Bayreuth Germany Physical Chemistry 1 University of Bayreuth Universitatsstr. 30 95447 Bayreuth Germany Physical Chemistry 1 - Colloidal Systems University of Bayreuth Universitatsstr. 30 95447 Bayreuth Germany

Herein, we fabricate hollow silica nanoparticles with exceptionally narrow size distributions that inherently possess two distinct length scales-tens of nanometers with regards to the shell thickness, and hundreds of nanometers in regards to the total diameter. We characterize these structures using dynamic and static light scattering （DLS and SLS）, small angle X-ray scattering （SAXS）, and transmission electron microscopy （TEM）, and we demonstrate quantitative agreement among all methods. The ratio between the radius of gyration （SLS） and hydrodynamic radius （DLS） in these particles equals almost unity, corresponding to ideal capsule behavior. We are able to resolve up to 20 diffraction orders of the hollow sphere form factor in SAXS, indicating a narrow size distribution. Data from light and X-ray scattering can be combined to a master curve covering a q-range of four orders of magnitude assessing all hierarchical length scales of the form factor. The measured SLS intensity profiles noticeably change when the scattering contrast between the interior and exterior is altered, whereas the SAXS intensity profiles do not show any significant change. Tight control of the aforementioned length scales in one simple and robust colloidal building block renders these particles suitable as future calibration standards.

Excitation and decay dynamics of 1s2s inner-shell double-vacancy states of neon atoms

Chinese Physics B 2008年第2期17卷 592-598页

The photo-excitation and Auger decay processes of inner-shell double vacancy states 1s2s2p^6（1,3^S）3s3p of neutral neon atoms have been studied theoretically. Multi-configuration Dirac-Fock （MCDF） calculations have been carried out, with electron correlation effects taken into consideration. The relaxation of core and excited orbitals and configuration interaction are found to be crucial to creating the double vacancy states by single photo-absorption. The predominant decay paths for the double vacancy states turn out to be of the LLM Auger decay to 1s 2s^22p^53s（3p）, KLL Auger decay to 1s^22s2p^43s3p, and KLM Auger decay to 1s^22p^63s（3p）. They lead to further Auger decay, creating the neon ions of multiple charge states. For both double and single vacancy states the spectator type of Auger process is dominated in all the Auger decay processes. Theoretical Anger electron spectra are presented for further investigations, experimental and theoretical.

Conditionally Optimal Weights of Evidence

引用

Acta Mathematicae Applicatae Sinica 2005年第2期21卷 247-256页

作者： stephan Morgenthaler Robert G.Staudte Ecole polytechnique federale de Lausanne (EPFL) SB IMA Station 8 1015 Lausanne SwitzerlandStatistics Department LaTrobe University Melbourne 3086 Australia

A weight of evidence is a calibrated statistic whose values in [0, 1]indicate the degree of agreement between the data and either of two hypothesis, one being treated asthe null (H_0) and the other as the alternative (H_1). A value of zero means perfect agreement withthe null, whereas a value of one means perfect agreement with the alternative. The optimality weconsider is minimal mean squared error (MSE) under the alternative while keeping the MSE under thenull below a fixed bound. This paper studies such statistics from a conditional point of view, inparticular for location and scale models.

Ontology Dynamics in a Data Life Cycle: Challenges and Recommendations from a Geoscience Perspective

引用

Journal of Earth Science 2014年第2期25卷 407-412页

作者： Xiaogang Ma Peter Fox Eric Rozell Patrick West stephan Zednik Tetherless World Constellation School of Science Rensselaer Polytechnic Institute

Ontologies are increasingly deployed as a computer-accessible representation of key semantics in various parts of a data life cycle and, thus, ontology dynamics may pose challenges to data management and re-use. By using examples in the field of geosciences, we analyze challenges raised by ontology dynamics, such as heavy reworking of data, semantic heterogeneity among data providers and users, and error propagation in cross-discipline data discovery and re-use. We also make recommendations to address these challenges：（1） communities of practice on ontologies to re- duce inconsistency and duplicated efforts; （2） use ontologies in the procedure of data collection and make them accessible to data users; and （3） seek methods to speed up the reworking of data in a Semantic Web context.

On Northern Hemisphere Wave Patterns Associated with Winter Rainfall Events in China

引用

Advances in Atmospheric Sciences 2018年第8期35卷 125-138页

作者： Claudia Christine stephan Yan Ho NG Nicholas P. KLINGAMAN National Centre for Atmospheric Science - Climate Department of Meteorology University of Reading Reading RG6 6BB United Kingdom Department of Meteorology University of Reading Reading RG6 6BB United Kingdom

During extended winter （November-April）, 43% of the intraseasonal rainfall variability in China is explained by three spatial patterns of temporally coherent rainfall, These patterns were identified with empirical orthogonal teleconnection （EOT） analysis of observed 1982-2007 pentad rainfall anomalies and connected to midlatitude disturbances. However, ex- amination of individual strong EOT events shows that there is substantial inter-event variability in their dynamical evolution, which implies that precursor patterns found in regressions cannot serve as useful predictors. To understand the physical nature and origins of the extratropical precursors, the EOT technique is applied to six simulations of the Met Office Unified Model at horizontal resolutions of 200-40 km, with and without air-sea coupling. All simulations reproduce the observed precursor patterns in regressions, indicating robust underlying dynamical processes. Further investigation into the dynamics associated with observed patterns shows that Rossby wave dynamics can explain the large inter-event variability. The results suggest that the appaxently slowly evolving or quasi-stationaxy waves in regression analysis are a statistical amalgamation of more rapidly propagating waves with a variety of origins and properties.

Prompted by a unique case of an ectomesenchymal chondromyxoid tumor(ECT) of the palate in a 54-year-old female, we reviewed the English and German literature on this entity until the end of 2016 using Pub Med. The search produced 74 lingual cases with a nearly equal sex distribution and a mean age of 39.3 years, and two extra-lingual cases sharing histological and immunohistological features including nodular growth, round, fusiform or spindle-shaped cellular architecture, and chondromyxoid *** showed the majority of cases to be positive for glial fibrillary acidic protein(GFAP), S-100 protein,glycoprotein CD57, pancytokeratin (AE1/AE3), and smooth muscle actin(SMA); in isolated cases there was molecular-genetic rearrangement or gain of Ewing sarcoma breakpoint region 1 (EWSR1) but no rearrangement of pleomorphic adenoma gene 1 (PLAG1). At present, ectomesenchymal cells that migrate from the neural crest are considered to play a pivotal role in tumor *** cases had a benign course, although there were three recurrences. Because of the rarity of this tumor and the need for differential diagnostic differentiation from myoepithelioma and pleomorphic adenoma, both oral surgeons and pathologists should be aware of this entity.
