If tanβ is large, down-type quark mass matrices and Yukawa couplings cannot be simultaneously diagonalized, and flavour violating couplings of the neutral Higgs bosons are induced at the 1-loop level. These couplings lead to Higgsmediated contributions to the decays Bs → μ+μ− and Bd → τ+τ−, at a level that might be of interest for the current Tevatron run, or possibly, at B-factories. We evalua...

We review the result of SUSY parameter fits based on frequentist analyses of experimental constraints from electroweak precision data, (g−2)μ, B physics and cosmological data. We investigate the parameters of the constrained MSSM (CMSSM) with universal soft supersymmetry-breaking mass parameters, and a model with common non-universal Higgs mass parameters in the superpotential (NUHM1). Shown ar...

A previously unknown intrinsic nonlinearity of standard fractionalsynthesizers is identified. A general analytical model for fractionalphased-locked loops (PLLs) that includes the effect of the nonlinearity is derived and an improvement to the synthesizer topology is discussed. Also, a new methodology for behavioral simulation is presented: the proposed methodology is based on an object-oriente...

The structure of the commutative Moufang loops (CML) with minimum condition for subloops is examined. In particular it is proved that such a CML Q is a finite extension of a direct product of a finite number of the quasicyclic groups, lying in the centre of the CML Q. It is shown that the minimum conditions for subloops and for normal subloops are equivalent in a CML. Moreover, such CML also ch...

Computation models such as circuits describe sequences of computation steps that are carried out one after the other. In other words, algorithm design is traditionally subject to the restriction imposed by a fixed causal order. We address a novel computing paradigm, replacing this assumption by mere logical consistency: We study non-causal circuits, where a fixed time structure within a gate is...

In 1981, SANDERS et al [1) described the "saw-tooth" sign, a sequence of rapid oscillations of the flow-volume loop tracing, as an aid for the detection of sleep apnea in awake patients. Such flow oscillations had been recognised before in fact ever since the flowvolume loop came into clinical practice at the beginning of the sixties but generally were discarded as a noisy disturbance, created ...

The regulation of biological networks relies significantly on convergent feedback signaling loops that render a global output locally accessible. Ideally, the recurrent connectivity within these systems is self-organized by a time-dependent phase-locking mechanism. This study analyzes recurrent fractal neural networks (RFNNs), which utilize a self-similar or fractal branching structure of dendr...

The polarization of Cosmic Microwave Background (CMB) photons is rotated as they pass through (ultralight-) axion string loops. Studying this birefringence can reveal valuable information about the axion-photon coupling and structure network. We develop an approximate analytic formalism identify a kernel function that be used to calculate two-point correlation for CMB induced by arbitrary Using...
