2881   Two new mixture models: Living with collinearity but removing its influence Two new mixture models: Living with collinearity but removing its influence    2003 Fitting equations to mixture data collected from highly constrained regions has challenged modelers for the past 35 years. Computer roundoff error, low precision of the estimates, and collinearity among the terms in the models are just a few of the problems encountered. It is well known that, due to collinearity, fitted models can contain coefficient estimates with magnitudes many hundreds or even a thousand times greater that the magnitude of the data values themselves. This can be very problem... 查看全文

2882   Statistical design of rockfall protective structures using a stochastic trajectory analysis model Statistical design of rockfall protective structures using a stochastic trajectory analysis model    2009 Classically used trajectory analysis models do not really account for the stochastic nature of the trajectory of falling rocks related to the variability of the impact process. The presented work focuses on the bouncing phase modelling in the case of the interaction of a boulder with a coarse granular soil. Impact simulations are first held using a Discrete Element Method. A statistical analysis of the numerical results is performed in order to build a stochastic impact model relating boulder ve... 查看全文

The pollen-based climatic and biome reconstructions provide the input data for these statistical models, i.e., annual mean temperature, total annual precipitation, annual actual evapotranspiration, annual potential evapotranspiration and biome type with a spatial resolution of 0.5° × 0.5° longitude/latitude. ... 查看全文

2885   Assessment of the effect of driver age on traffic accident involvement using log-linear models Assessment of the effect of driver age on traffic accident involvement using log-linear models    1998 Statistical models were developed to help understand the relationship between the driver age and several important accident-related factors and circumstances such as injury severity, collision types, average daily traffic (ADT), roadway character, speed ratio, alcohol involvement, and accident location. By using techniques of categorial analysis on the 1994 and 1995 Florida accident database, four log-linear models with three variables in each model with all possible two-way interactions were de... 查看全文

Yashiki;T. Suda;S. Watanabe    0 To understand hydrogen behavior. in V and V‐based alloys, two kinds of tensile tests were carried out for hydrogen‐charged miniature specimens: One is with hydrogen charging prior to testing (static charging), and the other is with hydrogen charging during straining (dynamic charging) with the continuous and intermittent ways. Static hydrogen‐charging effect: From the results of gas emission and microstructure, it was indicated that hydrogen can be trapped by lattice defects, dislocations, vacan 查看全文

2887   Experience of Continuous Subcutaneous Insulin Infusion in the Outpatient Management of Diabetic Teenagers Experience of Continuous Subcutaneous Insulin Infusion in the Outpatient Management of Diabetic Teenagers Dr. P.H. Winocour, D. Bhatnagar, P. Kalsi, V.F. Hillier and D.C. Anderson    2009 Of forty-five adolescent diabetic patients offered continuous subcutaneous insulin infusion (CSII) as part of a large feasibility study, 13 (28.9%) initially chose the treatment, but only 4 out of 11 who actually started CSII continued for one year (64% discontinuation rate). In contrast 30.4% of adults approached chose CSII, and 32% had discontinued after one year. Improvement in glycaemic control was poor, and clinical problems were more common in pump-treated teenagers than in adults. CSII do... 查看全文

2888   A Simple Model Predicts Experimental Folding Rates and a Hub-Like Topology A Simple Model Predicts Experimental Folding Rates and a Hub-Like Topology Thomas J. Lane and Vijay S. Pande*    2012 A simple model is presented that describes general features of protein folding, in good agreement with experimental results and detailed all-atom simulations. Starting from microscopic physics, and with no free parameters, this model predicts that protein folding occurs remarkably quickly because native-like states are kinetic hubs. A hub-like network arises naturally out of microscopic physical concerns, specifically the kinetic longevity of native contacts during a search of globular conformat 查看全文

Seeds during Controlled Deterioration Anna Atlante, Antonella Bobba, Lidia De Bari, Fabrizio Fontana, Pietro Calissano, Ersilia Marra and    0 Seed deterioration is poorly understood but remains an active area of research. Seeds of elm (Ulmus pumila L.) were aged at 37°C above water (controlled deterioration treatment, CDT) for various lengths of time to assess programmed cell death (PCD) and reactive oxygen species (ROS) production in embryonic tissues during a 5-d period. The hallmarks of PCD were identified in the elm seeds during CDT including TUNEL experiments, DNA laddering, cytochrome c (Cyt c) leakage and enzymatic activiti... 查看全文

2896   Sensitivity of polysilicon and polycide antenna MOS capacitor to ion implantation charging effects Sensitivity of polysilicon and polycide antenna MOS capacitor to ion implantation charging effects Tomasz Brozek    0 Wafer-charging monitors based on MOS capacitor antennas are a popular tool to assess the ion-implantation induced charging in IC manufacturing. We have found that silicidation of polysilicon antennas prior to ion implantation exposure simplifies the test tasks and shortens the cycle time for tool monitoring. The paper presents comparison of ion-implantation charging obtained on polysilicon as well as polycide gate capacitors. For polysilicon antennas a rapid thermal treatment was applied to rein... 查看全文

2897   Modelling temperature distributions and radon emission at Stromboli Volcano using a non-extensive statistical approach Modelling temperature distributions and radon emission at Stromboli Volcano using a non-extensive statistical approach    2004 Studying the hydrothermal features in a volcanic field is an important step in understanding eruption mechanisms as well as volcanically induced earthquakes. These processes can occur cyclically in a volcanic systems and could be explained by modern thermo-fluidodynamics theory. A computer model has been performed on the basis of field measurements. Radon emission are strictly correlated with magma degassing, the local temperature gradient, rock porosities and permeabilities. Anomalies in radon ... 查看全文

2898   Evaluating modeled intra- to multidecadal climate variability using running mann-whitney Z statistics Evaluating modeled intra- to multidecadal climate variability using running mann-whitney Z statistics    2012 An analysis method previously used to detect observed intra- to multidecadal (IMD) climate regimes was adapted to compare observed and modeled IMD climate variations. Pending the availability of the more appropriate phase 5 Coupled Model Intercomparison Project (CMIP-5) simulations, the method is demonstrated using CMIP-3 model simulations. Although the CMIP-3 experimental design will almost certainly prevent these model runs from reproducing features of historical IMD climate variability, these... 查看全文

2900   Quantification of CD-SEM wafer global charging effect on CD and CD uniformity of 193-nm lithography Quantification of CD-SEM wafer global charging effect on CD and CD uniformity of 193-nm lithography Chih-Ming Ke    0 For 90 nm technology and below, we need to fight for every nanometer to improve the CD uniformity (CDU). New materials, especially for low-k material, bring about not only complicated integration challenges, but also new metrology difficulties such as SEM image focus failure if using low landing energy (300V) on charging wafer (e.g. -300V). The wafer global charging will also distort the CD SEM magnification and result in CD measurement error. CD SEM venders propose that the distortion be correc... 查看全文
