This work investigates the problem of distinguishing modelling assumptions and numerical errors in sparseLagrangian FDF (Filtered Density Function) methods. A new interpretation of sparse modelling with Curl’s mixing, which does not require an additional observation scale nor filtering, is given. The diffusion effects induced by mixing, which were previously interpreted as numerical errors, are...

In the usual sequential addition enzyme immunoassays for drugs, the activity of the drug-labeled enzyme decreases continuously with time as more of it is bound to antibody. Sensitivity also decreases; the activity immediately after mixing is the most sensitive indicator of drug concentration. The reaction of enzyme-drug with antibody can be stopped by saturating the antibody with a larger quant...

Motivated by the recent determination of the top quark mass by the CDF collaboration, mt = 174± 10 −12 GeV, we review and update constraints on the parameters of the quark flavour mixing matrix VCKM in the standard model. In performing these fits, we use inputs from the measurements of |ǫ|, the CP-violating parameter in K decays, xd = (∆M)/Γ, the mixing parameter in B d-B 0 d mixing, the presen...

We compute isospin-violating meson-nucleon coupling constants and their consequent charge-symmetry-breaking nucleon-nucleon potentials. The couplings result from evaluating matrix elements of quark currents between nucleon states in a nonrelativistic constituent quark model; the isospin violations arise from the difference in the up and down constituent quark masses. We find, in particular, tha...

We propose an analysis framework to investigate different flow quantities such as vorticity, λ2 or the acceleration magnitude along vortex merge graphs and within their regions of influence. The explicit extraction of vortex merge graphs enables the application of statistical tools to investigate the vortex core lines themselves. The analysis tool provides common plots as scatter plots and para...

Anticipating improved determinations of mt, | Vub/Vcb |, BK and FB √ BB in the next five years we make an excursion in the future in order to find a possible picture of the unitarity triangle, of quark mixing and of CP-violation around the year 2000. We then analyse what impact on this picture will have the measurements of four possibly cleanest quantities: BR(K+ → π+νν̄), xd/xs, sin(2α) and sin...

Using the latest determinations of several theoretical and experimental parameters, we update the Unitarity Triangle analysis in the Standard Model. The basic experimental constraints come from the measurements of |Vub/Vcb|, ∆md, the lower limit on ∆ms, εK , and the measurement of the phase of the Bd–Bd mixing amplitude through the time-dependent CP asymmetry in B0 → J/ψK0 decays. In addition, ...

We investigate the effect on the sphaleron in the two Higgs doublet electroweak theory of including CP violation in the Higgs potential. To have better control over the relation between the sphaleron energy and the physical quantities in the theory, we show how to parametrize the Higgs potential in terms of physical masses and mixing angles, one of which causes CP violation. By altering this CP...

Low energy physics and left-right symmetry. Bounds on the model parameters. Abstract In any gauge model with spontaneous symmetry breakdown the gauge boson masses and their mixings are not independent quantities. They are interconnected through the vacuum expectation values (VEVs) of the Higgs sector. We discuss the low-energy experiments, namely electron-hadron, neutrino-hadron and neutrino-el...

Although there have been several numerical studies on particle dispersion in mixing layers, most of them have been conducted for temporally evolving mixing layers. In this study, numerical simulations of a spatially developing mixing layer are performed to investigate particle dispersion under various conditions. The full compressible Navier–Stokes equations are solved with a high-order compact...
