We study hadronic annihilation decays of B mesons within the perturbative QCD at collinear approximation. The regulation of endpoint divergences is performed with the help of an infrared finite gluon propagator characterized by a non-perturbative dynamical gluon mass. The divergences at twist-3 are regulated by a dynamical quark mass. Our results fit quite well the existent data of B0 → Ds K+ a...

We specify a function b0(t) in terms of the Lévy triplet such that lim supt→0Xt/b0(t) ∈ [1, 1.8] a.s. iff ∫ 1 0 Π (+)(b0(t))dt < ∞, for any Lévy process X with unbounded variation and Brownian component σ = 0. We show with example that there are cases when lim supt→0Xt/b(t) = 1 a.s., but b(t) is not asymptotically equivalent to b0(t), as t goes to 0. We achieve this by introducing an integral c...

Here u, b describe the flow velocity vector and the magnetic field vector respectively, p is a scalar pressure, ν > 0 is the kinematic viscosity and η > 0 is the magnetic diffusivity, while u0 and b0 are the given initial velocity and initial magnetic field respectively, with ∇ · u0 = ∇ · b0 = 0. If ν = η = 0, (1.1) is called the ideal MHD equations. Using the standard energy method, it can be ...

This study examined the safety of intracerebral inoculation of G207, an attenuated, replication-competent herpes simplex virus type 1 (HSV-1) recombinant, in nonhuman primates. Sixteen New World owl monkeys (Aotus nancymae [karyotype 1, formerly believed to be A. trivirgatus]), known for their exquisite susceptibility to HSV-1 infection, were evaluated. Thirteen underwent intracerebral inoculat...

If (A0, A1) and (B0, B1) are Banach couples and a linear operator T : A0 +A1 → B0 +B1 maps A0 compactly into B0 and maps A1 boundedly into B1, does T necessarily also map [A0, A1]θ compactly into [B0, B1]θ for θ ∈ (0, 1)? After 42 years this question is still not answered, not even in the case where T : A1 → B1 is also compact. But affirmative answers are known for many special choices of (A0, ...

ric energy e+e− collider. The fully reconstructed B+ → J/ψK+, B0 → J/ψK∗0, B+ → D̄0π+ and B0 → D−π+ decays are used to obtain the B+ and B0 production rates per bb̄ event, f (B+) = (67.5± 3.6± 4.8)% and f (B0) = (70.4+5.2 −5.1 ± 6.2)%. Assuming equal rates to B+ and B0 mesons in all channels produced at the Υ(5S) energy, we measure the fractions for bb̄ event transitions to the two-body and multi-...

We use the bootstrap procedure proposed by Storey (2002) and Storey, Taylor, and Siegmund (2004) to estimate the proportion of zero-alpha funds in the population, 0. This resampling approach chooses from the data such that an estimate of the Mean Squared Error ( ) of b0 ( ) dened as (b0 ( ) 0) is minimized. First, we compute b0 ( ) using equation (5) of the paper across a range of values ( = 0...
