From the recent measurement of parity nonconservation (PNC) in the Cs atom we have extracted the constant of the nuclear spin dependent electron-nucleon PNC interaction, κ = 0.44(7); the anapole moment constant, κa = 0.38(7); the strength of the PNC proton-nucleus potential, gp = 7 ± 1.4 (exp.) ± 1.5 (theor.); the π-meson-nucleon interaction constant, fπ ≡ hπ = [10 ± 2.5 (exp.) ± 3.5 (theor.)] ...

The self-energy and vertex QED radiative corrections (∼ Zα 2 f (Zα)) are shown to give a large negative contribution to the parity nonconserving (PNC) amplitude in heavy atoms. The correction −0.7(2)% found for the 6s − 7s PNC amplitude in 133 Cs brings the experimental result for this transition into agreement with the standard model. The calculations are based on a new identity that expresses...

We classify all possible limits of families of translates of a fixed, arbitrary complex plane curve. We do this by giving a set-theoretic description of the projective normal cone (PNC) of a subscheme, determined by the curve, of the P 8 of 3 × 3 matrices. In a sequel to this paper we determine the multiplicities of the components of the PNC. The knowledge of the PNC as a cycle is essential in ...

A preliminary all-order calculation of the spin-dependent (PNC) amplitude in Cs is carried out in an attempt to understand discrepancies in weak nucleon-nucleon coupling constants derived from atomic and nuclear experiments [W.C. Haxton and C.E. Wieman, Ann. Rev. Nucl. Part. Sci. 51, 261 (2001)]. We find that individual PNC matrix elements significantly change with more complete inclusion of th...

We consider the framework of Parameterized Complexity and we investigate the issue of which problems do admit eecient xed parameter parallel algorithms. In particular, we introduce two classes of eeciently parallelizable parameterized problems, PNC and FPP, according to the degree of eeciency we want to obtain. We sketch both some FPP-algorithms solving natural parameterized problems and a usef...

Physical-layer network coding (PNC) is a novel cooperative technique for two-way relay channel (TRC), where two users exchange information via intermediate relay node(s). On the other hand, the issue of green communications to reduce energy consumption has recently started to arouse much attention. This article studies the energyefficient resource allocation problem for orthogonal frequency div...

Parity nonconservation ~PNC! in atoms, described in the standard model of the electroweak interaction by exchange of Z bosons between bound electrons and nuclear quarks, leads to nonvanishing electric-dipole matrix elements between atomic states with the same parity. The dominant part of PNC matrix elements ~arising from the vector nucleon current! is proportional to a conserved weak charge QW ...

The class NC of problems solvable by bounded fan-in circuit families of logarithmic depth is known to be contained in logarithmic space L, but not much about the converse is known. In this paper we examine the structure of classes in between NC and L based on counting functions or, equivalently, based on arithmetic circuits. The classes PNC and C=NC, defined by a test for positivity and a test ...

Network Coding (NC) is a hot topic nowadays. Even though it has proven its applicability to wireless networks, there are still some questions whether network coding is feasible for small devices. To answer this question an implementation of the Partial Network Coding (PNC) buffer scheme is done on a wireless sensor and the results are described within this paper. Originally PNC was presented in...

The self-energy and vertex QED radiative corrections [approximately Zalpha2f(Zalpha)] are shown to give a large negative contribution to the parity nonconserving (PNC) amplitude in heavy atoms. The correction -0.73(20)% found for the 6s-7s PNC amplitude in 133Cs brings the experimental result for this transition into agreement with the standard model. The calculations are based on a new relatio...
