Measurement of the ratio of branching fractions B(B0→K∗0γ )/B(B0s→φγ ) and the directCP asymmetry inB 0→K∗0γ
No full textThe ratio of branching fractions of the radiative B decays B0→K⁎0γ and B0s→ϕγ has been measured using an integrated luminosity of 1.0 fb−1 of pp collision data collected by the LHCb experiment at a centre-of-mass energy of s√=7TeV. The value obtained is
B(B0→K⁎0γ)B(B0s→ϕγ)=1.23±0.06(stat.)±0.04(syst.)±0.10(fs/fd),
where the first uncertainty is statistical, the second is the experimental systematic uncertainty and the third is associated with the ratio of fragmentation fractions fs/fd. Using the world average value for B(B0→K⁎0γ), the branching fraction B(B0s→ϕγ) is measured to be (3.5±0.4)×10−5.
The direct CP asymmetry in B0→K⁎0γ decays has also been measured with the same data and found to be
ACP(B0→K⁎0γ)=(0.8±1.7(stat.)±0.9(syst.))%.
Both measurements are the most precise to date and are in agreement with the previous experimental results and theoretical expectations
Measurement of b-hadron masses
No full textMeasurements of b-hadron masses are performed with the exclusive decay modes B +→J/ψK +, B 0→J/ψK +, B0→J/ψKS0, Bs0→J/ψφ and Λb0→J/ψΛ using an integrated luminosity of 35pb -1 collected in pp collisions at a centre-of-mass energy of 7 TeV by the LHCb experiment. The momentum scale is calibrated with J/ψ→μ +μ - decays and verified to be known to a relative precision of 2 ×10 -4 using other two-body decays. The results are more precise than previous measurements, particularly in the case of the Bs0 and Λb0 masses
Stabilization of N-Myc is a critical function of Aurora A in human neuroblastoma
No full textIn human neuroblastoma, amplification of the MYCN gene predicts poor prognosis and resistance to therapy. In a shRNA screen of genes that are highly expressed in MYCN-amplified tumors, we have identified AURKA as a gene that is required for the growth of MYCN-amplified neuroblastoma cells but largely dispensable for cells lacking amplified MYCN. Aurora A has a critical function in regulating turnover of the N-Myc protein. Degradation of N-Myc requires sequential phosphorylation by cyclin B/Cdk1 and Gsk3. N-Myc is therefore degraded during mitosis in response to low levels of PI3-kinase activity. Aurora A interacts with both N-Myc and the SCF(Fbxw7) ubiquitin ligase that ubiquitinates N-Myc and counteracts degradation of N-Myc, thereby uncoupling N-Myc stability from growth factor-dependent signals
It worked yesterday: On (re-)performing electroacoustic music
No full textPlaying electroacoustic music raises a number of challenges for performers such as dealing with obsolete or malfunctioning technology and incomplete technical documentation. Together with the generally higher workload due to the additional technical requirements the time available for musical work is significantly reduced. Many of the issues have their roots in composers, publishers, performers and promoters considering how their work process could easily be adapted to the additional demands of electroacoustic music. It was also found that the employment of music technologists cannot sufficiently make up for incomplete documentation and inadequate archiving of compositions. Using case studies made up of single compositions and whole concerts, solutions are proposed, which the several parties could effortlessly employ to considerably ease the process of preparing and performing electroacoustic music. Finally hands-on methods on how performers can deal with the situation as it is today are proposed. It is being hoped that by implementing these strategies not only better performances of electroacoustic music will be facilitated but also that electroacoustic works in general will enjoy a longer life-span in the future, thus enabling the sustenance of a vivid electroacoustic repertoire
Calyptotheca tilbrooki Sebastian & Cumming 2016, n. sp.
No full textCalyptotheca tilbrooki n. sp. (Figs 3, 4, Table 2) Material examined. Holotype: MTQ G26785, GBR lagoon, Innisfail region, 17°59.1' S, 146°47.5' E, 29 April 2004, 34 m, coll. Seabed Biodiversity Project. Paratype: MTQ G26786, GBR lagoon, Shoalwater Bay region, 21°73.5' S, 149°.60.5' E, 4 October 2004, 16 m, coll. Seabed Biodiversity Project. Etymology. Honorific for Dr Kevin J. Tilbrook, in recognition of his contribution to the bryozoan collections at MTQ and to the taxonomy of Bryozoa. Description. Colony encrusting, multilaminar, forming thick upright multilamellar fronds (Fig. 3A, B), orange-red in ethanol; autozooids rectangular to irregularly polygonal (c. 0.5 x 0.5 mm; Table 2); frontal shield flattened to slightly convex with rounded pseudopores (average 23 per zooid), sparser or absent proximal to orifice, in zooid centre and towards zooid borders; interzooidal boundaries marked by thin raised lines of calcification with irregular marginal areolae. Primary orifice wider than long (c. 0.10 x 0.12 mm); lunula extending laterally, continuous with condyles; sinus a shallow rounded arc; condyles large, not serrate; raised nodular thickening proximal to orifice. Adventitious avicularia elongate-oval, some slightly wider distally (c 0.09 x 0.04 mm); marginal; most often in one or both proximal angles, sometimes on proximolateral margin; 0–3 per zooid, often absent; directed distally or distolaterally; proximal opesia semicircular, rostral foramen semielliptical, crossbar complete. Vicarious avicularia elongate-oval (c. 0.6 x 0.1 mm), without frontal shield; opesia oval, rostral foramen triangular with concave distal sides, crossbar complete, with large columella directed distally. Ooecium immersed, not raised above surrounding zooids, wider than long (c. 0.4 x 0.5 mm), sometimes crossed by sutural lines; pseudopores of both ooecium and ovicellate zooid frontal shield similar in size but in greater density (c. 73 vs 23 pseudopores per zooid) than autozooidal frontal shield, sometimes 2–3 pseudopores share same pit; pronounced orificial dimorphism, ovicellate orifice twice as wide (c. 0.24 vs 0.12 mm) and longer (c. 0.15 vs 0.10 mm) than autozooidal orifice; sinus wide and very shallow; condyles rounded, not serrate; suboral umbo present. Remarks. Calyptotheca tilbrooki n. sp. is distinguished by its growth form of thick multilamellar mounds and fronds, long, oval vicarious avicularia, elongate-oval, marginal adventitious avicularia, pronounced orificial dimorphism, and distinctive high-density pseudopores in the ooecia and frontal shields of ovicellate zooids. Seven Calyptotheca species have been described with vicarious avicularia, viz C. capitifera (Canu & Bassler, 1929), C. conica, C. inclusa, C. obscura Harmelin, López de la Cuadra & García-Gómez, 1989, C. orbiculata Harmer, 1957, C. reniformis Tilbrook, 2006 (unpubl. data in Cumming & Tilbrook 2014) and C. wulguru n. sp. All of these species except C. capitifera have the primitive form of vicarious avicularia that resemble autozooids with perforated frontal shields, but with greatly enlarged orifices. Those of C. capitifera therefore appear most similar to those of C. tilbrooki n. sp. (without a perforated frontal shield). Canu & Bassler (1929, pl. 32, fig. 5) described “the spatulate shape of interzooidal avicularia” of C. capitifera (not C. capitifera of Harmer 1957; see Cumming & Tilbrook 2014, p. 160). The vicarious avicularia of C. tilbrooki n. sp. are not spatulate but elongate-oval with acuminate rostral foramen, while those of C. capitifera, are semicircular and there are no adventitious avicularia. The combination of shape and position of the adventitious avicularia of C. tilbrooki n. sp. is unique within the genus. The elongate oval shape does not conform to the C. wasinensis subgroup described above, despite having a similarly marginal position. The adventitious avicularia of C. thornelyae are most similar to those of C. tilbrooki n. sp., but pseudopore density of autozooidal and ooecial calcification is identical; there is no orificial dimorphism and vicarious avicularia are lacking (Ryland & Hayward 1992, p. 260). Calyptotheca tilbrooki n. sp. has the most pronounced known orificial dimorphism amongst Calyptotheca species, with the ovicellate orifice double the width of the autozooidal orifice. A greater density of pseudopores on the ooecium was also described by Harmer (1957, p. 1020) in C. fossulata, which is distinguished from C. tilbrooki n. sp. by the lack of vicarious avicularia and having rounded marginal adventitious avicularia typical of the C. wasinensis subgroup. Distribution. Calyptotheca tilbrooki n. sp. is known only from the GBR lagoon. One colony was collected from the Innisfail area at 34 m and one colony from the Shoalwater Bay region, North of Yeppoon at 16 m.Published as part of Sebastian, Pascal & Cumming, Robyn L., 2016, Three new species of Calyptotheca (Bryozoa: Lanceoporidae) from the Great Barrier Reef, tropical Australia, pp. 467-479 in Zootaxa 4079 (4) on pages 472-475, DOI: 10.11646/zootaxa.4079.4.6, http://zenodo.org/record/105086
