Cosmological Parameter Estimation: Method [PDF]
, 2003 CMB anisotropy data could put powerful constraints on theories of the evolution of our Universe. Using the observations of the large number of CMB experiments, many studies have put constraints on cosmological parameters assuming different frameworks ...

$\mu$ Parameter from Dynamical Rearrangement of U(1) and $\theta$ Parameter [PDF]
, 2011 We study the generation of $\mu$ parameter from the dynamical rearrangement of local U(1) symmetry in a five-dimensional model and discuss phenomenological implications on the $\theta$ parameter, under the assumption that supersymmetry is broken by the ...

Nonlinear current response of one- and two-band superconductors
, 2005 We have calculated the nonlinear current of a number of single band s-wave electron-phonon superconductors. Among issues considered were those of dimensionality, strong electron-phonon coupling, impurities, and comparison with BCS.

Second international workshop on particle physics and the early universe (COSMO-98), 1999 The discussion of cosmological parameters used to be a source of embarrassment to cosmologists. Today, measurements of the cosmological parameters are leading the way into the era of precision cosmology. The CMB temperature is measured to four significant figures, T_0=2.7277+/-0.002 K; the Hubble constant is now determined with a reliable error ...

On a Reverse Half-Discrete Hardy-Hilbert’s Inequality with Parameters
Mathematics, 2019 By means of the weight functions, the idea of introduced parameters, and the Euler-Maclaurin summation formula, a reverse half-discrete Hardy-Hilbert’s inequality and the reverse equivalent forms are given.

Theory of the critical current in two-band superconductors with application to MgB2
, 2005 Using a Green's function formulation of the superfluid current j_s, where a momentum q_s is applied to the Cooper pair, we have calculated j_s as a function of q_s, temperature, and impurity scattering for a two-band superconductor.

Probe of process of multiple-loop chains of parallel and consecutive joints [PDF]
E3S Web of Conferences, 2020 The article describes the formation of low-frequency currents in ferromagnetic oscillatory circuits. As a result of parallel and serial connection of multi-loop ferroresonance circuits, the frequencies of harmonics of the second-order amplitude of soft ...

, 1995 A parameter-free, mean-field, multi-orbital Hubbard model with nonspherical Coulomb and exchange interactions, implemented around all-electron local-density approximation (LDA) calculations, correctly predicts the band-gap energy, the absence of ...

Optimal hedging and parameter uncertainty [PDF]
, 2007 We explore the impact of drift parameter uncertainty in a basis risk model, an incomplete market in which a claim on a non-traded asset is optimally hedged using a correlated traded stock.
