No full textGenus Bharatalbia Cook, 1967 Bharatalbia: Cook, 1974 a, pp. 363–364, figs. 1605–1612. Bharatalbia: Smith, 1991, pp. 487–496, figs. 31–41. Bharatalbia: Smith & Cook, 1991, p. 577. Bharatalbia: Smith et al., 2001, p. 613, figs. 378, 379. Bharatalbia: Smith et al., 2010, p. 554, figs. 15.379, 15.380. Diagnosis. Larva: Unknown. Adults (modified from Smith 1991): Idiosoma elliptical in shape. Dorsal and ventral shields separate from one another, with ventral shield extending well onto dorsal surface of idiosoma anteriorly and completely surrounding dorsal shield. Dorsal shield with surface reticulate or with an embossed appearance; ventral shield with surface coarsely reticulate and with rough, scaly edges. Dorsal shield bearing one pair of glandularia and lacking or bearing one pair of well-defined longitudinal ridges. Dorsal furrow bearing no glandularia, one pair of glandularia and one pair of setae on pair of anterolateral platelets, or two pairs of glandularia on two pairs of platelets, one anterolateral and other posterolateral. Fourth coxal plate bearing coxoglandularium II, and bearing large projection associated with opening for insertion of fourth leg. Ventral shield bearing one pair of glandularia in region posterior to fourth coxal plates. Genital field subterminal and bearing sixteen to twenty pairs of acetabula; excretory pore borne dorsally on ventral shield; acetabular plates fused with ventral shield in females. First leg of males with distal segments unmodified or slightly modified; third leg of males with tibia bearing or lacking a ventral projection; fourth leg of males with distal segments unmodified or slightly modified. Pedipalp with all segments, but especially femur and tibia, extremely slender and long; tibia lacking ventral projection and bearing two sessile, slender setae distoventrally. Type species. Bharatalbia sucirapalpis Cook. Species included. Bharatalbia (s. s.) sucirapalpis Cook (India), B. (Bharatalbiella) talinapalpis Cook (India), B. (Japonalbia) ibarakiensis Imamura (Japan), B. (J.) cooki Smith (western North America), B. (J.) ohitaensis Imamura (Japan), B. (J.) longipalpis Imamura (Japan), B. (J.) tsugaruensis Imamura (Japan), B. (J.) rotunda Imamura (Japan), B. (J.) surensis Smith (western North America). Distribution. Holarctic (India, Japan, western North America). Discussion. Cook (1974 a) and Smith (1991) considered Bharatalbia to be a distinct genus. Smith & Cook (1991) and Smith et al. (2001, 2010) followed this treatment, as we do here. See Smith (1991) for a discussion of the subgeneric classification of this genus.Published as part of Smith, Ian M., Cook, David R. & Gerecke, Reinhard, 2015, Revision of the status of some genus-level water mite taxa in the families Pionidae Thor, 1900, Aturidae Thor, 1900, and Nudomideopsidae Smith, 1990 (Acari: Hydrachnidiae), pp. 111-156 in Zootaxa 3919 (1) on page 132, DOI: 10.11646/zootaxa.3919.1.6, http://zenodo.org/record/24458
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

Navinaxonopsis Cook 1967
No full textSubgenus Navinaxonopsis Cook, 1967 Axonopsis (Navinaxonopsis): Cook, 1974 a, p. 334, figs. 1393, 1397, 1398, 1400, 1406. Diagnosis of adults. Character states of genus Brachypodopsis. Fourth leg of males with tibia slender proximally but greatly expanded distally, and with tarsus curved. Type species. Axonopsis (Navinaxonopsis) abnormipes Cook. Species included. Brachypodopsis (N.) abnormipes (Cook) (India), B. (N.) persica (Pešić) (Iran, Turkey). Distribution. India and western Asia. Discussion. Cook (1974 a) considered Navinaxonopsis to be a subgenus of Axonopsis and Pešić (2004) followed that treatment. Here we propose to transfer the taxon as a subgenus to the genus Brachypodopsis. As in the case of Kalobrachypoda, the species of Navinaxonopsis appear to represent a divergent offshoot of the species complex typified by Brachypodopsis baumi Halik and the status of this taxon will also need to be reevaluated when the phylogeny of the genus Brachypodopsis is more completely known.Published as part of Smith, Ian M., Cook, David R. & Gerecke, Reinhard, 2015, Revision of the status of some genus-level water mite taxa in the families Pionidae Thor, 1900, Aturidae Thor, 1900, and Nudomideopsidae Smith, 1990 (Acari: Hydrachnidiae), pp. 111-156 in Zootaxa 3919 (1) on page 140, DOI: 10.11646/zootaxa.3919.1.6, http://zenodo.org/record/24458
