No full textTranscript (45 pages) of a phone interview by Becky B. Lloyd with Fernando Torres-Gil in Los Angeles on September 18, September 23, and October 15, 2010Torres-Gil (b. 1948) was born in Salinas, California. He was six months old when he contracted polio while living in Castroville, California. He was initially sent to Monterey County General Hospital in Salinas for treatment. His parents were immigrants from Mexico and were agricultural workers in California. He discusses his immediate and extended family, the family dynamics related to his illness, recovery and subsequent surgeries, and the support system developed with his family. He was locally treated by his physician, Dr. Englehorn. When initial treatments proved ineffective, Dr. Englehorn, a Shriner, arranged for Torres-Gil\u27s treatment at Shriners Hospital in San Francisco. His first hospital stay was at age 2 in 1950. He left the hospital after that stay using braces and crutches. He was subsequently hospitalized, for lengthy stays ranging from three to nine months, for various surgeries between 1954 and 1966. He describes these surgeries and his recollections of care and activities while in the hospital. He continues to use braces and crutches. He has never regained use of his right leg. Torres-Gil discusses his schooling, both while in the hospital and through the public school system. He talks about his progress, challenges and accommodation. He earned Associate and Bachelor degrees in California; Master\u27s and Doctorate degrees at Brandeis University. He has served on various councils for three US presidents, including currently on the Council on Aging. The interview concludes with Dr. Torres-Gil discussing the onset of, challenges with and adapting to post-polio syndrome. Interview is part of the Polio Oral History Project. Interviewer: Becky B.

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)

Pará: São Geraldo do Araguaia, Serra dos Martírios-Andorinhas, caminho para o morro do Passat, 6°17’33.6” S, 48°32’40.5” W, 24 May 2019, fl., fr., K .N.L. Alves, A.S.B. Gil, L. Schneider, C.S. Nunes, J.M. Cardoso, R. Batista-Silva, R. Nunes & N.P. Pinto-Silva 244 (holotype: MG; isotypes: IAN, RB). Diagnosis:— Similar to Triumfetta lappula, but it differs from it for having 6-celled ovary, glands on the androgynophore and lack of membranous urceolus. It differs from all other species of Triumfetta due to ten glands on androgynophore. Shrubs ca. 2 m tall. Stems brownish, cylindrical, pubescent, with yellowish stellate trichomes of slender, long and thicker, shorter hairs. Leaves simple; stipules 3.1–5.2 × 0.9–1.1 mm, elliptic, ciliate, with simple and biradiated trichomes, apices acute; petioles 0.3–6 cm long, tomentose, with yellowish stellate trichomes; blades 1.2–9.2 × 0.4– 6.8 cm, entire to slightly 3-lobed, discolor, ovate (basal ones) to elliptic (upper ones), base cuneate with 3 basal teeth on each side with cupuliform glands, margins irregularly serrate, apices acuminate, adaxial surface pubescent, with slender biradiated and stellate trichomes over the surface and thicker stellate trichomes on the nerves, abaxial surface pubescent to tomentose, with slender and elongated stellate trichomes over the surface, and thicker and elongated stellate trichomes on the nerves. Inflorescence axillary, cymes 3-flowered; peduncles 1.4–2.2 mm long; bracts 2.4–3.5 × 0.7–1 mm, lanceolate, pubescent, with simple and biradiated trichomes densely toward the apex; pedicels 0.8–1.9 cm long, pubescent, with simple and stellate trichomes; bracteoles 1.2–1.6 × 0.1 mm, lanceolate to oblong, ciliate, with simple and biradiated trichomes. Flower pentamerous, hermaphroditic; floral bud oblong, 1.7–2.7 mm long; sepals 2.7–3.3 × 0.2–0.4 mm, oblong, pubescent, with biradiated and stellate trichomes, appendices ca. 0.1 mm long; petals absent; androgynophore 0.4–0.5 mm long, glands 10, orbicular; without membranaceous urceolus; stamens 10–12, free, filaments 1–2.4 mm long, glabrous, anthers bi-thecate; ovary ovoid, ca. 0.1 × 0.1 mm, 6-celled, style 2–2.4 mm long, glabrous, stigma 1, bifid. Fruits immature, 0.2 × 0.1 mm, globose, epicarp pubescent, with glandular trichomes, ca. 50 uncinate spines, hyaline, glabrous; seeds not seen. Distribution and habitat:— This species is only known from its type-locality in São Geraldo do Araguaia County, Serra dos Martírios-Andorinhas, Pará State, Northern Brazil (Fig. 3). Serra dos Martírios-Andorinhas is limited by two conservation units: Área de Proteção Ambiental de São Geraldo do Araguaia (APA Araguaia) and Parque Estadual da Serra dos Martírios-Andorinhas (PESAM) (SECTAM 2006; Silva 2009; IDEFLOR-BIO 2019). The area is in the Cerrado -Amazon ecotone and hosts different habitats such as alluvial ombrophilous dense forest, campo cerrado, campo sujo and secondary vegetation (SECTAM 2006). It is in the “arc of deforestation”, which is the region mostly threatened by deforestation in the Brazilian Amazon (Silva 2009, IDEFLOR-BIO 2019). The new species grows on the roadside of a pasture, at elevation of ca. 170 m. Conservation status:— The new species was found at APA Araguaia, in a pasture area, by the roadside. Despite being placed at a conservation unit, the area suffers intense anthropic stress, with agribusiness expansion. Only one sample of Triumfetta decaglandulata was collected and it was impossible to obtain information of its extent of occurrence (EOO) and area of occupancy (AOO). The genus Triumfetta is widely distributed in Brazil, and it is often present in open areas, but few specimens are represented in herbaria. Thus, this lack of distribution data frequently affects the conservation status assessment of the species. According to the IUCN Red List Categories and Criteria (2012), Triumfetta decaglandulata should be considered as Data Deficient (DD) because only the typespecimen is known and appropriate data on abundance and/or distribution are unknown. However, we emphasize that its natural habitat located at APA Araguaia is under anthropic impact, and therefore, attention should be redirected to the preservation of this unique known population. Etymology:— The epithet “ decaglandulata ” refers to the ten glands observed in the species’ androgynophore. Taxonomic affinities:— According to the classification by Lay (1950), T. decaglandulata fits the Triumfetta sect. Lappula DC. based on its rigid spines, as well as the series Uncinatae Sprague & Hutch., based on its uncinate spines. The new species is mainly featured by the ten glands on the androgynophore and by the absence of membranaceous urceolus and petals (Fig. 1F). Most of Triumfetta have pentamerous flowers and five glands on the androgynophore (Lay 1950; Halford 1997), except for Triumfetta acahuizotlanensis González-Martínez, J. Jiménez Ram. & Rios-Carrasco (2016: 273), which has tetramerous flowers and four glands (Jiménez-Ramírez et al. 2016), as well as for T. lappula, which is the only species lacking glands (Lay 1950). T. decaglandulata is the only known species belonging to genus Triumfetta that has ten glands on the androgynophore. Triumfetta decaglandulata possess absent petals, character also shared with T. lappula and T. centralis Halford (1997: 543). Triumfetta albida (Domin) Halford (1997: 562) and T. longipedunculata Halford (1997: 562) also have absent petals or, when present, often inconspicuous. Although the new species and T. lappula, are registered in the Americas, T. albida, T. centralis, and T. longipedunculata occur in Australia. Triumfetta albida differs from the new species by the presence of 30 or more stamens (vs. 10-12 stamens) and ovary 2-celled (vs. ovary 6-celled). Triumfetta centralis also differs by the ovary 2-celled (vs. ovary 6-celled), and the toothed stigma (vs. bifid stigma). Triumfetta longipedunculata differs by the presence of ca. 60 stamens (vs. 10-12 stamens) and 3-lobed stigma (vs. bifid stigma). Triumfetta decaglandulata resembles T. lappula in stem indument and leaf shape, lack of petals and geographic distribution – both species are recorded in Pará State, Northern Brazil. However, it differs from T. lappula because it has 10-12 stamens (vs. 15 stamens), ovary 6-celled (vs. 2-celled), ten glands on the androgynophore (vs. androgynophore absent) and lack of membranaceous urceolus (vs. inconspicuous urceolus) (see Gual-Díaz & Pérez 2018).Published as part of Cardoso, Jesiane Miranda, Fernandes-Júnior, Aluísio José & Gil, André Dos Santos Bragança, 2022, Triumfetta decaglandulata (Grewioideae, Malvaceae), a new species from the Cerrado-Amazon ecotone, Northern Brazil, pp. 287-293 in Phytotaxa 545 (3) on pages 288-292, DOI: 10.11646/phytotaxa.545.3.4, http://zenodo.org/record/654154
On the aberration–retardation effects in pulsars
No full textThe magnetospheric locations of pulsar radio emission region are not well known. The actual form of the so-called radius-to-frequency mapping should be reflected in the aberration-retardation (A/R) effects that shift and/or delay the photons depending on the emission height in the magnetosphere. Recent studies suggest that in a handful of pulsars the A/R effect can be discerned with respect to the peak of the central core emission region. To verify these effects in an ensemble of pulsars, we launched a project analysing multifrequency total intensity pulsar profiles obtained from the new observations from the Giant Meterwave Radio Telescope (GMRT), Arecibo Observatory (AO) and archival European Pulsar Network (EPN) data. For all these profiles, we measure the shift of the outer cone components with respect to the core component, which is necessary for establishing the A/R effect. Within our sample of 23 pulsars, seven show the A/R effects, 12 of them (doubtful cases) show a tendency towards this effect, while the remaining four are obvious counterexamples. The counterexamples and doubtful cases may arise from uncertainties in the determination of the location of the meridional plane and/or the core emission component. Hence, it appears that the A/R effects are likely to operate in most pulsars from our sample. We conclude that in cases where those effects are present the core emission has to originate below the conal emission region
