The Chinese capital Beijing is one of the global megacities where the effects of rapid economic growth have led to complex air pollution problems that are not well understood. In this study, ambient particle number size distributions in Beijing between 2004 and 2006 are analysed as a function of regional meteorological transport. An essen-5 tial result is(More)
Stochastic models of tumorigenesis have been developed to investigate the implications of experimental data on tumour induction in wild-type and p53-deficient mice for tumorigenesis mechanisms. Conventional multistage models in which inactivation of each p53 allele represents a distinct stage predict excessively large numbers of tumours in p53-deficient(More)
Atmospheric CO 2 concentrations are higher now than they have been in the past 25 million years. It is becoming increasingly important to understand the nature and processes of the CO2 sinks, on a global scale, in order to make predictions of future atmospheric composition. Accurate measurements of tropospheric CO2 abundance with global-coverage, a few(More)
Anisotropic triangular graphene monolayers grown on a Ru(0001) surface represent unique two-dimensional templates for creating ordered, large-scale assembly of functional molecules. Using scanning tunneling mi-croscopy and spectroscopy, we demonstrate the selective adsorption and the formation of ordered molecular arrays of iron phthalocyanine and pentacene(More)
Either diagnostic delay or tumour biology are possible factors governing the degree of spread at diagnosis of cervical cancer. To try to identify the most important parameter contributing to advanced stage, the duration of symptoms were recorded from patients scheduled for radiotherapy (n = 141) or radical hysterectomy (n = 36). In 146 cases tumour(More)
This discussion paper is/has been under review for the journal Biogeosciences (BG). Please refer to the corresponding final paper in BG if available. Abstract Predictive understanding of northern peatland hydrology is a necessary precursor to understanding the fate of massive carbon stores in these systems under the influence of present and future climate(More)
Laser return intensity, delivering the surface reflectivity information in the laser wavelength, is function of many variables and ignored in most application projects. However, by a process of SILC (Spectral Imagery LIDAR Composite), laser return points can be fused with accurate spectral attributes from the high quality images provided by aerial cameras(More)
We report progress in assessing the feasibility of a new satellite-based laser-sounding instrument to measure CO2 concentrations in the lower troposphere from space. 1. Introduction CO 2 measurements from ice cores show that atmospheric CO 2 concentrations are higher now than they have been in the past 400,000 years. It is becoming increasingly important to(More)
