摘要:For many years, the coexistence of Helicobacter pylori ( H. pylori ) infection and atherosclerotic diseases in a disproportional number of patients has inspired the presumption that a causal relationship exists between the conditions. This presumption was evidenced by the simulta...

摘要:The mechanical properties of a molding compound on a packaged integrated circuit (IC) were measured by spherical nanoindentation using a 50 μm radius diamond tip. The molding compound is a heterogeneous material, consisting of assorted diameters of glass beads embedded in an...

摘要:Soil microorganisms play an important role in regulating nutrient cycling in terrestrial ecosystems. Most of the studies conducted thus far have been confined to a single forest biome or have focused on one or two controlling factors, and few have dealt with the integrated e...

摘要:This paper develops a multivariable integrated evaluation (MVIE) method to measure the overall performance of climate model in simulating multiple fields. The general idea of MVIE is to group various scalar fields into a vector field and compare the constructed vector field again...

摘要:Vector quantities, e.g., vector winds, play an extremelyimportant role in climate systems. The energy and water exchanges betweendifferent regions are strongly dominated by wind, which in turn shapes theregional climate. Thus, how well climate models can simulate vector fieldsdir...

摘要:This paper investigates the performance analysis of diversity combining over flat fading channels subject to additive impulsive noise. Specifically, the impulsive noise follows the symmetric α-stable (SαS) distribution. Tradi- tionally, this is a difficult problem since the ...

摘要:Physically based distributed hydrological models are widely used forhydrological simulations in various environments. As with conceptual models,they are limited in data-sparse basins by the lack of streamflow data forcalibration. Short periods of observational data (less than 1 y...

摘要:The volatility of organic aerosols remains poorly understood due to thecomplexity of speciation and multiphase processes. In this study, weextracted humic-like substances (HULIS) from four atmospheric aerosolsamples collected at the SORPES station in Nanjing, eastern China, ...

摘要:In order to investigate the negative ions in the boreal forest we have performed measurements to chemically characterise the composition of negatively charged clusters containing highly oxygenated molecules (HOMs). Additionally, we compared this information with the chemical...

摘要:The determination of area-averaged evapotranspiration (ET) at the satellite pixel scale/model grid scale over a heterogeneous land surface plays a significant role in developing and improving the parameterization schemes of the remote sensing based ET estimation models and genera...
