A.J. Potter (1918-1980): The career and creative achievement of an Irish composer in social and cultural context
No full textA. J. Potter (1918-1980) was one of the most significant composers working in Ireland in the latter part of the twentieth century. This thesis surveys his career and creative achievement, which have not hitherto been subjected to detailed scrutiny. The opening chapter presents a biographical overview: its first part outlines the circumstances of Potter's childhood and early adulthood, including his studies with Vaughan Williams at the Royal College of Music in London, his period of service in the British Army during World War II and his subsequent three-year sojourn in Africa; the second continues the narrative from 1951, when he settled permanently in Ireland, up to his death in 1980. In addition to detailing events of note in his private and professional life, an important subsidiary focus of this section is to depict the impoverished and culturally marginalised nature of Irish musical life at this period and describe the frustrations that these conditions engendered for the composer and his contemporaries. The remaining chapters are devoted to an examination of Potter's major works. Chapter 2 considers four student compositions that were written or conceived in the late 1930s and were subsequently revised when he resumed composing in 1949 after a creative silence of over a decade. Chapter 3 is divided in two parts: the first delineates the salient features of his mature creative aesthetic, while the second provides an account of his later orchestral works. The remaining chapters explore his choral music and stage works, which, in addition to the scores previously described, constitute his most noteworthy achievements

Disturbances in peripheral blood B cell subpopulations in autoimmune patients
No full textA variety of cell surface markers are being used to identify B cell subpopulations in peripheral blood. Currently at least eight subpopulations have been identified. Analyses of healthy individuals indicate that in general the various B cell subpopulations exist in relatively similar ratios in unrelated individuals. It has been demonstrated that B lymphocyte homeostasis is disturbed during infection and autoimmune disease. In this review we compare the distribution of B cell subpopulations in the peripheral blood of patients with systemic lupus erythematosus, rheumatoid arthritis and primary Sjogren's syndrome with each other, and with healthy individuals. The different autoimmune diseases have distinct changes in the B cell subpopulations. Understanding the nature of these B subpopulation signatures will potentially impact understanding the mechanisms of disease, diagnosis and therapy
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
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
Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
No full textFirst 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)

Body color dark brown to black, wings fumose, macropterous; length of forewings 6.5-7.0 mm; length of body 7.5-8.5 mm. Ninth sternum with large, round lobe or vesicle, covered by dense mat of short hairs, directed toward and overlapping apex. Tenth tergum bisected medially. Ninth tergum with large V-shaped notch along posterior margin. Epiproct long and thin, apex extending over posterior margin of tergum 8; dorsal plate extending to 1/3 length of epiproct, apical aspect deeply notched, forming sharply pointed, paired processes; basal lobe long and thin and directed upward in sinuate shape laterally, with median groove dorsally that terminates in pointed apex, tip bearing small membranous section that might be expandable; ventral surface well sclerotized, smooth and covered by few pit-like sensory structures (Figs. 7-12). Female. Body and wing color similar to male, macropterous; length of forewings 9.0-10.0 mm; length of body 9.5- 10.5 mm. Subgenital plate broader than long, with narrow hairless area medially, posterior margin broadly rounded, bearing V-shaped median notch (Figs. 15-16). Larva. Length 9.0-11.0 mm. Head, thorax and abdomen clothed in short, fine hairs. Femur with few long hairs on dorsal surface, ventral margin with two rows of short stout spines; tibia with sparse row of long, thin hairs along ventral margin. Mesosternal Yridge with wide reaching arms that extend nearly to bases of mesocoxal legs. Right mandible, as in Stewart and Stark (2002), with both terminal and basal teeth large and forked, fringe of short spines covering basal half of mandible; lacinia pointed, spines below terminal teeth short, longer hair-like spines on outer margin, extending along ½ of outer margin. Epiproct directed posteriorly on male larva. Etymology. The species name is based on the fact that the type and most of the paratypes were collected in the Mission Mountains of Montana. Diagnosis. Bolshecapnia missiona is most similar to B. sasquatchi, but it can be separated in the details of the epiproct and the posterior margin of the female subgenital plate. The epiproct is long and very thin apically in B. missiona with a pointed tip (Fig. 7), while in B. sasquatchi it is much shorter and ends in a bluntly rounded tip (Fig. 1), appearing foot shaped in lateral aspect (Fig. 4). Also, the dorsal plate covers nearly half of the epiproct in B. sasquatchi (Fig. 6) while in B. missiona it only reaches the basal third (Fig. 12). The female of B. sasquatchi has a subgenital plate with a straight, flat posterior margin (Fig. 13- 14), but the female of B. missiona exhibits a rounded subgenital plate that terminates in a median Vshaped notch (Figs. 15-16). The notch is always present but varies somewhat in size and shape. However, the female illustrated by Nebeker and Gaufin (1967) shows little or no notch. The larva is similar to the B. spenceri description in Stewart and Stark (2002) but shows slight differences in the shape of the mandible and lacinia. Remarks. Bolshecapnia missiona is known mostly from first order and small second order streams at elevations from 750 to 1500 meters above sea level. Grant Creek is a freestone stream fed directly by snowmelt and cold seeps. High elevation reaches flow in small cascading pools and riffles over small angular cobble and gravel with an open southerly exposure. Twenty-meter-high steep slopes at streamside release cold seepage into thick moss over deep sand and gravel mixed with woody debris. Stream channels at lower elevation sites are mixed sand, gravel, and larger rounded cobble in long riffles forming a channel bordered by Alnus stands at streamside and open meadows on the floodplain. These lower reaches include an extensive hyporheic zone confirmed by nearby domestic water wells that penetrate 20-40 meters of saturated gravels as much as 200 meters laterally from the surface stream.
