We report on measurements of low-mass electron pairs in 450 GeV p-Be, p-Au, and 200 GeV/nucleon S-Au collisions at central rapidities. For the proton induced interactions, spectra are, within systematic errors, satisfactorily explained by from hadron decays, whereas system an enhancement over hadronic contributions a factor 5.0±0.7(stat)±2.0(syst) invariant mass range 0.2<m<1.5GeV/c2 is observed. The properties excess suggest that it arises two-pion annihilation ππ→e+e−.Received 2 March...
The status of the research on muon colliders is discussed and plans are outlined for future theoretical experimental studies. Besides continued work parameters a 3-4 0.5 TeV center-of-mass (CoM) energy collider, many studies now concentrating machine near 0.1 that could be factory s-channel production Higgs particles. We discuss various components in such colliders, starting from proton accelerator needed to generate pions heavy-Z target proceeding through phase rotation decay ($\pi \to \mu...
ConspectusMolecular mechanical force fields have been successfully used to model condensed-phase and biological systems for a half century. By means of careful parametrization, such classical can be provide useful interpretations experimental findings predictions certain properties. Yet, there is need further improve computational accuracy the quantitative prediction biomolecular interactions properties that depend on wave functions not just energy terms. A new strategy called explicit...
Abstract Recent studies of the high energy‐conversion efficiency nanofluidic platform have revealed enormous potential for efficient exploitation electrokinetic phenomena in nanoporous membranes clean‐energy harvesting from salinity gradients. Here, reverse electrodialysis (NF‐RED) consisting vertically aligned boron‐nitride‐nanopore (VA‐BNNP) is presented, which can efficiently harness osmotic power. The power density VA‐BNNP reaches up to 105 W m −2 , several orders magnitude higher than...
A sample of 4 x 10(5) events from the decay K(+)-->pi(+)pi(-)e(+)nu(e) (K(e4)) has been collected in experiment E865 at Brookhaven Alternating Gradient Synchrotron. The analysis these data yields new measurements K(e4) branching ratio [(4.11+/-0.01+/-0.11) 10(-5)], s-wave pi scattering length [a(0)(0) = 0.216+/-0.013(stat)+/-0.004(syst)+/-0.005(theor)], and form factors F, G, H hadronic current their dependence on invariant mass.

A sample more than 400,000Ke4 events with low background has been collected by Experiment 865 at Brookhaven Alternate Gradient Synchrotron.

A search for lepton flavor violating decays, K+ --> mu+ pi-, e+ pi+ mu-, and pi0 was performed using the data collected in Experiment E865 at Brookhaven Alternating Gradient Synchrotron. No signal found any of decay modes. At 90% confidence level, branching ratios are less than 3.0x10(-9), 6.4x10(-10), 5. 2x10(-10), 5.0x10(-10), 3.4x10(-9), respectively.
Scanning X-ray microprobes are unique tools for the nanoscale investigation of specimens from life, environmental, materials and other fields sciences. Typically they utilize absorption fluorescence as contrast mechanisms. Phase is a complementary technique that can provide strong with reduced radiation dose weakly absorbing structures in multi-keV range. In this paper development segmented charge-integrating silicon detector which provides simultaneous differential phase reported. The be...
ABSTRACT The main results of this paper show how asymptotic relations are preserved when integrated or differentiated in the sense fractional operators. In some them, concept regular variation plays a role. We derive extension Karamata integration theorem and monotone density theorem, among others. offer several approaches that provide deeper insight into relationships between different concepts. Illustrative applications differential equations also presented.
