Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
First evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)

Genetic heterogeneity in Cornelia de Lange syndrome (CdLS) and CdLS-like phenotypes with observed and predicted levels of mosaicism
Cornelia de Lange syndrome (CdLS) is a multisystem disorder with distinctive facial appearance, intellectual disability and growth failure as prominent features. Most individuals with typical CdLS have de novo heterozygous loss-of-function mutations in NIPBL with mosaic individuals representing a significant proportion. Mutations in other cohesin components, SMC1A, SMC3, HDAC8 and RAD21 cause less typical CdLS

Rise of subgen. Rhoicosphenula Lange-Bert. To the genus level, and description of a new Gomphosphenia s.s. species from Puerto Rico
The subgenus Rhoicosphenula Lange-Bert. has a unique character combination that differentiates it from Gomphosphenia subgen. Gomphosphenia Lange-Bert. In particular, Rhoicosphenula has striae/areola features that are similar to Gomphosphenia, but is di?erentiated from that genus by also having pseudosepta present on both poles of the valves, copulae with septa at one of the poles, and frustules almost rectangular in girdle view. Together, this character combination strongly supports it as an independent genus following modern diatom-taxonomy criteria. Moreover, the only species of Rhoicosphenula known so far was collected from a peculiar acidic and dystrophic habitat, whilst most Gomphosphenia s.s. species colonize medium-conductivity, alkaline inland waters. On the basis of LM and SEM studies, we also propose a species of Gomphosphenia (G. patrickiana Cantonati, Lange-Bert., Kociolek & A.A.Saber, sp. nov.) as new to science. Te new species is mainly defned by its valve outline and dimensions, length to breadth ratio, striation density, and geographical distribution. It was found in several samples of two streams in Puerto Rico, sometimes with high relative abundance. Gomphosphenia patrickiana Cantonati, LangeBert., Kociolek & A.A.Saber, sp. nov. was much more abundant in the stream with lower nutrient (in particular P) concentrations, and higher ecological integrity. Te new species seems to prefer moderately alkaline freshwater habitats with medium-high conductivity and oligo-to mesotrophic conditions, with moderate tolerance to N enrichment. Also noteworthy is the occurrence of the new species in streams with above-average magnesium concentrations (due to the local geology). Tis Neotropical, warm-water species might be a potential indicator of global warming effects

Search for B -> J/psi D decays
We report a search for B -> J/psi D decays, based on a sample of 124 x 10(6) B (B) over bar events collected with the BABAR detector at the PEP-II storage ring of the Stanford Linear Accelerator Center. No significant signal is found. We obtain upper limits on the branching fractions of 1.3 x 10(-5) for B-0 -> J/psi(D) over bar (0) and 1.2 x 10(-4) for B+ -> J/psi D+ at 90% confidence level

We perform a full amplitude analysis of the process , where refers to either or . A new charmoniumlike state that decays to is observed with a significance of . Its mass is () MeV/ and width is () MeV. The hypothesis is favored over the hypothesis at the level of . The analysis is based on the 980 data sample collected by the Belle detector at the asymmetric-energy collider KEKB
Search for the rare decays J/ψ → Dsρ+ + c.c. and J/ψ → D0K∗0 + c.c
A search for the rare decays of J/psi -> D-S(-) rho(+) + c.c. and J/psi -> <(D)over bar(0)<(K)over bar*(0) + c.c. is performed with a data sample of 225.3-million J/psi events collected with the Beijing Spectrometer III detector. No evident signal is observed. Upper limits on the branching fractions are determined to be beta(J/psi -> D-S(-)rho(+) + c.c.) < 1.3 x 10(-5) and beta(J/psi -> <(D)over bar(0)<(K)over bar*(0) + c.c.) < 2.5 x 10(-6) at the 90% confidence level.AuthorOverflow(378
