A search for baryon-number violating Ξ_{b}^{0} oscillations is performed with a sample of pp collision data recorded by the LHCb experiment, corresponding to an integrated luminosity of 3  fb^{-1}. The baryon number at the moment of production is identified by requiring that the Ξ_{b}^{0} come from the decay of a resonance Ξ_{b}^{*-}→Ξ_{b}^{0}π^{-} or Ξ_{b}^{'-}→Ξ_{b}^{0}π^{-}, and the baryon n...

We investigate the properties of r-mode and inertial mode of slowly rotating, non-isentropic, Newtonian stars, by taking account of the effects of the Coriolis force and the centrifugal force. The Coriolis force is the dominant restoring force for both r-mode and inertial mode, which are also called rotational mode in this paper. For the velocity field produced by the oscillation modes the r-mo...

introduction: acute kidney injury (aki) is a common postoperative complication of cardiac surgery, which is associated with an increased risk of morbidity and mortality. this study investigated the frequency of postoperative aki in low risk adult patients undergoing off-pump coronary artery bypass grafting (cabg).materials & methods: all consecutive adult patients of american society of anesthe...

Figure 1: Left: Principle of operation of superconducting microresonator detectors, following[1]. The absorbed photon energy breaks Cooper electron pairs in a thin superconducting film (a) which is part of a lithographed microresonator circuit (b). The breaking of Cooper pairs causes a change in the surface reactance and resistance of the film, leading to a shift in the resonance frequency fr a...

A general theoretical analysis of a 3D generic TENG structure is presented. Using dimensionless formulation, it demonstrated that the optimal geometry does not depend on frequency moving dielectric but external ohmic impedance for maximum power output inversely proportional to frequency. It also found energy cube size TENG, square triboelectric charge density σT, and angular ω dielectric. In ca...

This work proposes a microwave angular displacement sensor with wideband matching based on impedance transformer. According to the design requirement of microstrip transformer (load-to-source 250-to-50 Ω, centre frequency 2.40 GHz) Chebyshev response, proposed is explored for high bandwidth sensitivity 11.18 MHz/degree.

The statistics of velocity fluctuations of turbulent Taylor-Couette flow are examined. The rotation rates of the inner and outer cylinders are varied while keeping the Taylor number fixed to 1.49×10(12) [O(Re)=10(6)]. The azimuthal velocity component of the flow is measured using laser Doppler anemometry. For each experiment 5×10(6) data points are acquired and carefully analyzed. Using extende...

We show that the proportionately spaced emission bands in the dynamic spectrum of the Crab pulsar (Hankins T. H. & Eilek J. A., 2007, ApJ, 670, 693) fit the oscillations of the square of a Bessel function whose argument exceeds its order. This function has already been encountered in the analysis of the emission from a polarization current with a superluminal distribution pattern: a current who...

– Glasses have an excess number of low-frequency vibrational modes in comparison with most crystalline solids. We show that such a feature necessarily occurs in solids with low coordination. In particular, we analyze the density D(ω) of normal-mode frequencies ω and the nature of the low-frequency normal modes of a recently simulated system [1], comprised of weakly compressed spheres at zero te...
