Unreliability will be a major issue for computers built from components at nanometer scales.
      
Systematic results of major and trace element geochemistry and Sm-Nd isotopic geochemistry on detrital sedimentary rocks of Precambrian to Triassic in the Ganzi-Songpan block and Longmen Mountains are presented.
      
Leaves and soil samples were simultaneously collected from the ten major distribution areas in Northwest China at altitudes from 394 m to 1 987 m above sea level, at latitudes from 36°10'N to 44°33'N, and at longitudes from 81°43'E to 106°37'E.
      
There are 61 major peraluminous granitic bodies in Tibet (TPGs) along the south of the Bangong Co-Gêrzê-Amdo-Nujiang suture, whose lithology includes tourmaline granite, muscovite granite and two-mica granite.
      
The salt exclusion effect during the gas hydrate formation will cause an increase in major ion concentrations in the pore waters that diffused upward such as Cl.
      
By quick neutron mobilization method, an 40Ar-39Ar age of mica from the major ore vein is determined, yielding ore-forming ages of 144 Ma and 147 Ma.
      
Combining these age data with the occurrences of the main granite body, the patched body, the major ore veins and Na-Ta mineralization, the paper discusses their formation orders and relationships.
      
This paper reviews major advances in the studies of ore genesis and metallogenic regularity and progresses in mineral exploration of porphyry Cu deposits in the belt.
      
This paper briefly presents the research progress of the State Major Basic Research Project 2001CB309400, "Theory and Application for Retrieval and Fusion of Spatial and Temporal Quantitative Information from Complex Natural Environment".
      
By means of the analysis method of wave processes, major cycles of sedimentary wave process in this basin have been studied.
      
Authors collected 38 sedimentary boreholes and numerous seismic profiles from previous publications to delineate the Holocene sedimentation rate of six major depositional sinks in the middle-lower Changjiang River basins and its river coast.
      
In this century, China started facing five major challenges in the energy field: energy supply, shortage of liquid fuel, environmental pollution, green house gas (GHG) emission, and energy supply in rural areas.
      
Compared with the expanded trials in clinics, only very limited efforts were made to probe the engineering issues involved, which turns out to be a major obstacle for the successful operation of brain hypothermia resuscitation.
      
From the viewpoint of biothermal medical engineering, the major theories and strategies for administering brain cooling can generally be classified into three categories: heat transfer, oxygen transport and cooling strategy.
      
The experimental results showed that the major congener was octa-chlorinated dibenzo-p-dioxin (OCDD) in the gas phase and the low chlorinated congeners were the major products in the solid phase.
      
With the rapid improvement of computer performance, tremendous heat generation in the chip becomes a major serious concern for thermal management.
      
The intensive soil-water interaction in unsaturated expansive soil is one of the major reasons for slope failures.
      
Life cycle and performance based seismic design of major bridges in China
      
The idea of life cycle and performance based seismic design of major bridges is introduced.
      
The vulnerability analysis and progressive collapse analysis, as well as risk assessment, are also proposed to be the important issues to study in order to guide the seismic design of major bridges in the future.
