    LIN-2 and FRM-3 regulate the synaptic abundance but not surface expression level of AChRs.

    No full text
    (A-D) ACR-16::RFP and UNC-29::RFP synaptic abundance were decreased in lin-2null and frm-3null mutants. Representative images (A, C, scale bar 10 μm) and mean puncta intensity (B, D) are shown. The wild type is normalized to 1. (E-H) ACh- and Levamisole-activated currents were unaltered in lin-2null and frm-3null mutants. Representative traces (E, G) and mean current amplitude (F, H) are shown. (I, J) GABA-activated currents were decreased by 50% in lin-2null mutants but were unchanged in frm-3null mutants. Data are mean ± SEM (***, p < 0.001 when compared to control; one-way ANOVA). The number of worms analyzed for each genotype is indicated in the bar.</p

    Inverse systems of spectra and generalizations of a theorem of W.H. Lin

    In this thesis we generalize a theorem of W. H. Lin. Lin's results are concerned with the homotopy and cohomotopy of an inverse system of spectra {P-k }. Using the quadratic construction we construct an inverse system of spectra {P-k(E)} We generalize Lin's results by studying the homotopy and cohomotopy of {P-k(E)}

    A 2 h periodic variation in the low-mass X-ray binary Ser X-1

    No full text
    Spectroscopy of the low-mass X-ray binary Ser X-1 using the Gran Telescopio Canarias have revealed a ?2 h periodic variability that is present in the three strongest emission lines. We tentatively interpret this variability as due to orbital motion, making it the first indication of the orbital period of Ser X-1. Together with the fact that the emission lines are remarkably narrow, but still resolved, we show that a main-sequence K dwarf together with a canonical 1.4 M? neutron star gives a good description of the system. In this scenario, the most likely place for the emission lines to arise is the accretion disc, instead of a localized region in the binary (such as the irradiated surface or the stream-impact point), and their narrowness is due instead to the low inclination (?10°) of Ser X-1

    LIN-39 does not regulate TRN fate markers in AVM.

    No full text
    (A) AVM was posteriorly displaced in lin-39(n1760) mutants, but the expression of TRN fate marker uIs115[mec-17p::TagRFP] was not affected in lin-39 mutants. (B) The displaced AVM also expressed the TRN fate marker zdIs5[mec-4p::GFP] in lin-39 mutants. Scale Bars = 100 μm. (TIF)</p

    Search for new hadronic decays of h c and observation of h c → p p ¯ η ppη p\overline{p}\eta

    Abstract A search for the hadronic decays of the h c meson to the final states p p ¯ pp p\overline{p} π + π − π 0, p p ¯ η ppη p\overline{p}\eta , and p p ¯ pp p\overline{p} π 0 via the process ψ(3686) → π 0 h c is performed using (4.48 ± 0.03) × 108 ψ(3686) events collected with the BESIII detector. The decay channel h c → p p ¯ η ppη p\overline{p}\eta is observed for the first time with a significance greater than 5σ and a branching fraction of (6.41 ± 1.74 ± 0.53 ± 1.00) × 10 −4, where the uncertainties are statistical, systematic, and that from the branching fraction of ψ(3686) → π 0 h c . Strong evidence for the decay h c → p p ¯ pp p\overline{p} π + π − π 0 is found with a significance of 4.9σ and a branching fraction of (3.84 ± 0.83 ± 0.69 ± 0.58) × 10 −3. The significances include systematic uncertainties. No clear signal of the decay h c → p p ¯ pp p\overline{p} π 0 is found, and an upper limit of 6.59 × 10 −4 on its branching fraction is set at the 90% confidence level
