TL;DR: In this article, the authors reported the discovery of Ξc(3055)0, observed by its decay into the final-state ΛD0, and presented the first observation and evidence of the decays of the branching fractions, masses and widths with improved accuracy.
Abstract: We report the discovery of Ξc(3055)0, observed by its decay into the final-state ΛD0, and present the first observation and evidence of the decays of Ξc(3055)+ and Ξc(3080)+ into ΛD+. We also perform a combined analysis of the ΛD+ with the Σc++K- and Σc∗++K- decay modes to measure the ratios of branching fractions, masses and widths with improved accuracy. We measure the ratios of branching fractions B(Ξc(3055)+→ΛD+)/B(Ξc(3055)+→Σc++K-)=5.09±1.01±0.76, B(Ξc(3080)+→ΛD+)/B(Ξc(3080)+→Σc++K-)=1.29±0.30±0.15, and B(Ξc(3080)+→Σc∗++K-)/B(Ξc(3080)+→Σc++K-)=1.07±0.27±0.04, where the uncertainties are statistical and systematic. The analysis is performed using a 980 fb-1 data sample collected with the Belle detector at the KEKB asymmetric-energy e+e- collider.

TL;DR: In this paper, the work function of NiCo2O4 was calculated by density functional theory using the plane-wave basis set and used to estimate the field enhancement factor, which showed a low turn-on field of 1.86 V μm−1 at 1 μA cm−2 and current density of 686 μAcm−2 at 3.2 Vμm −1, with field enhancement factors β = 1460 and good field emission current stability.
Abstract: Electron emission properties of electrodeposited spinel NiCo2O4 nanosheet arrays grown on Ni foam have been studied. The work function of NiCo2O4 was calculated by density functional theory using the plane-wave basis set and used to estimate the field enhancement factor. The NiCo2O4 nanosheet arrays exhibited a low turn-on field of 1.86 V μm−1 at 1 μA cm−2 and current density of 686 μA cm−2 at 3.2 V μm−1, with field enhancement factor β = 1460 and good field emission current stability. The field emission properties of the NiCo2O4 nanosheet arrays showed enhanced performance compared to chemically prepared NiCo2O4 nanosheets. Hence, the nanosheet arrays have great potential as robust high performance vertical structure electron emitters for future flat panel displays and vacuum electronic device applications.

TL;DR: The first Belle search for a light CP-odd Higgs boson, A^{0), that decays into low mass dark matter, χ, in final states with a single photon and missing energy is reported on.
Abstract: We report on the first Belle search for a light CP-odd Higgs boson, A^{0}, that decays into low mass dark matter, χ, in final states with a single photon and missing energy. We search for events produced via the dipion transition ϒ(2S)→ϒ(1S)π^{+}π^{-}, followed by the on-shell process ϒ(1S)→γA^{0} with A^{0}→χχ, or by the off-shell process ϒ(1S)→γχχ. Utilizing a data sample of 157.3×10^{6} ϒ(2S) decays, we find no evidence for a signal. We set limits on the branching fractions of such processes in the mass ranges M_{A^{0}}<8.97 GeV/c^{2} and M_{χ}<4.44 GeV/c^{2}. We then use the limits on the off-shell process to set competitive limits on WIMP-nucleon scattering in the WIMP mass range below 5 GeV/c^{2}.

TL;DR: The results implicate a conserved, but largely unstudied, threonine residue of the Ssp DnaE intein (Thr69) as the mediator of conformational strain through hydrogen bonding and the strain imposed by this residue is shown to position the splice junction in a manner that enhances the rate of the N‐S acyl shift substantially.
Abstract: Protein splicing is an autocatalytic process where an “intein” self-cleaves from a precursor and ligates the flanking N- and C-“extein” polypeptides. Inteins occur in all domains of life and have myriad uses in biotechnology. Although the reaction steps of protein splicing are known, mechanistic details remain incomplete, particularly the initial peptide rearrangement at the N-terminal extein/intein junction. Recently, we proposed that this transformation, an N-S acyl shift, is accelerated by a localized conformational strain, between the intein's catalytic cysteine (Cys1) and the neighboring glycine (Gly-1) in the N-extein. That proposal was based on the crystal structure of a catalytically competent trapped precursor. Here, we define the structural origins and mechanistic relevance of the conformational strain using a combination of quantum mechanical simulations, mutational analysis, and X-ray crystallography. Our results implicate a conserved, but largely unstudied, threonine residue of the Ssp DnaE intein (Thr69) as the mediator of conformational strain through hydrogen bonding. Further, the strain imposed by this residue is shown to position the splice junction in a manner that enhances the rate of the N-S acyl shift substantially. Taken together, our results not only provide fundamental understanding of the control of the first step of protein splicing but also have important implications in various biotechnological applications that require precursor manipulation.
