On the Leray-Hopf Extension Condition for the Steady-State Navier-Stokes Problem in Multiply-Connected Bounded Domains

Employing the approach of A. Takeshita [Pacific J. Math., Vol. 157 (1993), 151--158], we give an elementary proof of the invalidity of the Leray-Hopf Extension Condition for certain multiply connected bounded domains of R^n, n=2,3, whenever the flow through the different components of the boundary is non-zero. Our proof is alternative to and, to an extent, more direct than the recent one proposed by J.G. Heywood [J. Math. Fluid Mech. Vol. 13 (2011), 449--457]

Bs Mixing, DeltaGamma_s and CP Violation

We discuss the results from the Tevatron experiments on mixing and {\sf CP} violation in the $B_s-\bar{B}_s^0$ system, with particular emphasis to the first measurements of the decay width-difference $\Delta\Gamma_s$ and the {\sf CP} violating phase $\beta_s$ using flavor tagging information. We also briefly review the charge asymmetry measurements in semileptonic $B_s$ decays and in $B^\pm \to J/\psi K^\pm$ decays.Comment: 6 pages, 4 figures, Pub.

Mixmaster Chaoticity as Semiclassical Limit of the Canonical Quantum Dynamics

Within a cosmological framework, we provide a Hamiltonian analysis of the Mixmaster Universe dynamics on the base of a standard Arnowitt-Deser-Misner approach, showing how the chaotic behavior characterizing the evolution of the system near the cosmological singularity can be obtained as the semiclassical limit of the canonical quantization of the model in the same dynamical representation. The relation between this intrinsic chaotic behavior and the indeterministic quantum dynamics is inferred through the coincidence between the microcanonical probability distribution and the semiclassical quantum one.Comment: 9 pages, 1 figur

Norway's approach to monetary policy

The goal of monetary policy as conducted by Norges Bank is to maintain low and stable inflation. The operational target of monetary policy is explicitly defined in a consumer price inflation rate of approximately 2.5 percent over time. Norges Bank sets its interest rate instrument with a view to achieving the inflation target over a two-year horizon, and it will normally tolerate deviations of actual inflation from target that are not in excess of plus or minus 1 percentage point. In general, the direct effects on consumer prices resulting from changes in interest rates, taxes, excise duties, and extraordinary temporary circumstances shall not be taken into account.Monetary policy - Norway ; Banks and banking, Central - Norway ; Norges Bank

Japan's approach to monetary policy

The goal of monetary policy as conducted by the Bank of Japan is to contribute to the sound development of the national economy through the pursuit of price stability. The objective of price stability, however, is not precisely defined as it has been for other central banks. Following the implementation of the new Bank of Japan Law in 1998, the monetary policy framework is characterized by central bank independence, the primacy of the price stability objective, instrument independence, and policy decisions made by a monetary policy committee with regular meetings and published minutes. At its meetings, the monetary policy committee discusses the economic and financial situation and then decides matters relating to monetary policy, including the following: the guideline for money market operations; the official discount rate; reserve requirements ratios; the Bank's view of economic and financial developments; and the types, terms, and conditions of bills and bonds used in money market operations.Monetary policy - Japan ; Bank of Japan ; Banks and banking, Central - Japan

Switzerland's approach to monetary policy

Monetary policy as conducted by the Swiss National Bank is aimed at maintaining price stability in the medium term. Between 1980 and 1999, the Bank used the seasonally adjusted monetary base as monetary target and as indicator. Given the continually distorted indicator value of the monetary base after 1996, the Bank fundamentally reviewed its modus operandi. As of the beginning of 2000, the Swiss National Bank (SNB) considers price stability to be achieved with an annual inflation (CPI) rate of less than 2 percent. The Bank bases its monetary policy decisions on a medium-term (three-year) inflation forecast. Despite similarities to inflation targeting, the new framework differs from it in one important respect, namely, it does not contain an institutional commitment to an inflation target as the overriding objective of monetary policy.Monetary policy - Switzerland ; Banks and banking, Central - Switzerland ; Swiss National Bank
