Motivated by the recent determination of the top quark mass by the CDF collaboration, mt = 174 ± 10 −12 GeV, we review and update the constraints on the parameters of the quark flavour mixing matrix VCKM in the standard model. In performing our fits, we use inputs from the measurements of the following quantities: (i) |ǫ|, the CP-violating parameter in K decays, (ii) ∆Md, the mass difference du...

Bq−Bq mixing with q = d or q = s is governed byM −iΓ/2 with the hermitian 2×2 matrices M q and Γ. The (1, 2) element of M q − iΓ/2 induces Bq → Bq transitions. The mass matrix element M q 12 stems from the dispersive part of the box diagram in Fig. 1, which is obtained from the full diagram by replacing the loop integral with its real part. The decay matrix element Γq12 is calculated from the a...

The work described in this paper is focused on evaluating the effect of the processing method and nanoclay (montmorillonite) content on the tensile, compressive, and impact properties of clay-epoxy nanocomposites. Nanocomposites are synthesized by two methods: mechanical mixing and shear mixing. Both these methods are capable of producing bulk quantities of clay-epoxy nanocomposites. X-ray diff...

High-entropy (H-E) alloys, bulk metallic glasses (BMGs) and high-entropy BMGs (HE-BMGs) were statistically analyzed with the help of a database of ternary amorphous alloys. Thermodynamic quantities corresponding to heat of mixing and atomic size differences were calculated as a function of composition of the multicomponent alloys. Actual calculations were performed for configurational entropy (...

Accurate supersymmetric spectra are required to confront data from direct and indirect searches of supersymmetry. SuSeFLAV1 is a numerical tool which is capable of computing supersymmetric spectra accurately for various supersymmetric breaking scenarios applicable even in the presence of flavor violation. The program solves MSSM RGEs with complete 3× 3 flavor mixing at 2-loop level and one loop...

Statistics for the structure and time-evolution of a large, complex, evolving, real-world network is presented. The data comes from the communication flow in an Internet community of around 25 000 users with user activity logged for about 500 days. The vastness and precise time resolution of an Internet community offers unique possibilities to monitor social network formation and dynamics. The ...

Massive data sets describing vector fields from computational fluid dynamic simulations on high-performance computers can no longer be visualized directly by displaying the data values at each point in time and space, but require data reduction to analyze the essential properties. We describe early results of work in progress to visualize a dataset of 500GB of raw data, consisting out of multip...

Total alkalinity (TA) is one of the few measurable quantities that can be used together with other quantities to calculate concentrations of species of the carbonate system (CO2, HCO3 , CO3 , H, OH). TA and dissolved inorganic carbon (DIC) are conservative quantities with respect to mixing and changes in temperature and pressure and are, therefore, used in oceanic carbon cycle models. Thus it i...

The predictions of Galactic chemical evolution models for D and 3He are described in connection with those on the other Galactic quantities for which observational constraints are available. Models in agreement with the largest set of data predict deuterium depletions from the Big Bang to the present epoch smaller than a factor of 3 and do not allow for D/H primordial abundances larger than ∼ 4...
