The dependence of galaxy clustering on local density provides an effective method for extracting non-Gaussian information from surveys. two-point correlation function (2PCF) a complete statistical description Gaussian field. However, the late-time field becomes due to non-linear gravitational evolution and higher-order summary statistics are required capture all its cosmological information. Us...

The turn-on speed of nMOS transistors (nMOST) is of paramount importance for robust Charged Device Model (CDM) protection circuitry. In this paper the nMOST turn-on time has been measured for the first time in the sub-halve nanosecond range with a commercial e-beam tester. The method may be used to improve CDM-ESD hardness by investigating the CDM pulse responses within circuit. Furthermore it ...

Since global warming due to greenhouse gas emissions is no respecter of geographical boundaries of countries, concerted mitigation activities such as Clean Development Mechanism (CDM), are suitable. In this mechanism, some developed countries can gain certified emission reduction credits from emission reduction actions undertaken in developing countries. Thus, the data of greenhouse gas emissio...

By directly probing mass distributions, gravitational lensing offers several new tests of the CDM paradigm. Lens statistics place upper limits on the dark matter content of elliptical galaxies. Galaxies built from CDM mass distributions are too concentrated to satisfy these limits, so lensing extends the “concentration problem” in CDM to elliptical galaxies. The central densities of the model g...

Collaborative modelling enables dispersed users to develop component-based system models in group settings. A realization of such an approach requires coordinating and maintaining the causality of the users’ activities. We propose the Collaborative DEVS Modelling (CDM) approach and its realization based on the Computer Supported Collaborative Work (CSCW) and the Discrete Event System Specificat...

We devise a method to measure the abundance of satellite halos in gravitational lens galaxies, and apply our method to a sample of 7 lens systems. After using Monte Carlo simulations to verify the method, we find that substructure comprises f sat = 0.02 (median, 0.006 < f sat < 0.07 at 90% confidence) of the mass of typical lens galaxies, in excellent agreement with predictions of CDM simulatio...

We examine the constraints on theories of galaxy formation that are obtained from observations of damped Ly (DL) systems, assuming they are gaseous protodisks in dark matter halos. Using the Press-Schechter formalism, we nd that the mixed dark matter model, with HDM = 0:3, CDM = 0:65, b = 0:05, and h = 0:5, is ruled out because the number of galactic halos at z ' 3 is too small to account for t...
