The Cauchy-Schwarz (CS) inequality-one of the most widely used and important inequalities in mathematics-can be formulated as an upper bound to the strength of correlations between classically fluctuating quantities. Quantum-mechanical correlations can, however, exceed classical bounds. Here we realize four-wave mixing of atomic matter waves using colliding Bose-Einstein condensates, and demons...

We calculate the electromagnetic corrections to the isospin invariant mixing angle and to the two eigenphases for the s-, p1/2and p3/2-partial waves for π −p elastic and charge exchange scattering. These corrections have to be applied to the nuclear quantities in order to obtain the two hadronic phase shifts for each partial wave. The calculation uses relativised Schrödinger equations containin...

The neutrino signal from SN1987A is analysed with respect to spin-flavour oscillations between electron antineutrinos, ν̄e, and muon neutrinos, νμ, by means of a maximum likelihood analysis. Following Jegerlehner et al. best fit values for the total energy released in neutrinos, Et, and the temperature of the electron antineutrino, Tν̄e , for a range of mixing parameters and progenitor models are...

We extend the resummation of dimensionally-regulated amplitudes to next-to-next-to-leading poles. This requires the calculation of two-loop anomalous dimension matrices for color mixing through soft gluon exchange. Remarkably, we find that they are proportional to the corresponding one-loop matrices. Using the color generator notation, we reproduce the two-loop single-pole quantities H introduc...

We suggest a simple highly predictive ansatz for charged lepton and light neutrino mass matrices, based on the assumption of universality of Yukawa couplings. Using as input the charged lepton masses and light neutrino masses, the six parameters characterizing the leptonic mixing matrix VPMNS , are predicted in terms of a single phase φ, which takes a value around φ = π 2 . Correlations among v...

Mixing rubber in an internal mixer is a complex nonlinear process in which viscosity of the rubber is one of the key quantities concerning end product quality. Since viscosity can’t be measured online, soft sensor methods for modelling viscosity are investigated to establish an online control of viscosity. This paper presents a black-box approach to modelling viscosity using an adaptive neuro-f...

At modern electron accelerators with highly polarized, intense, high duty factor beams double polarization coincidence experiments became feasible with good statistical accuracy. The strong potential towards the precise determination of small nucleon structure quantities is illustrated by two recent examples from MAMI. The measurement of GE in the quasifree reaction D(~e, e′~n)p lead to a new p...

Some thermodynamic quantities were obtained for the interactions of poly [2-(3-mesityl-3-methylcyclobutyl)2-hydroxyethyl methacrylate] with alcohols, ketones, acetates, aromatics and alkanes by inverse gas chromatography in the temperature range 160-200◦C. The specific retention volumes, V ◦ g , weight fraction activity coefficients of solute probes at infinite dilution, Ω1 , Flory-Huggins ther...

The polymerase chain reaction (PCR) is one of the most widely used techniques in the field of molecular biology. PCR makes it possible to produce useable quantities of any particular sequence of DNA by systematic amplification of a single sample. The basic process involves mixing the template sequence with a collection of the four deoxyribosenucleotides and DNA polymerase along with a starting ...

We present a new technique for simultaneous measurement of chromatic dispersion and Brillouin shift distribution along conventional, single-mode optical fibers used in telecommunications. It is based on performing Brillouin Optical Time Domain Analysis (BOTDA) over the four-wave mixing generated by two low-power pumps (<10 mW). Unlike others, this technique can measure any arbitrary value ofdis...
