Joseph Milford Nicholson (b. 1935) : pioneer trombone historian
No full textInterest in the history and development of the trombone and its literature escalated during the last half of the twentieth century. As curricula for doctoral degrees began to develop during the 1950s, trombonists in advanced degree programs began to recognize lapses in the history of the instrument. One of the earliest doctoral documents that focused upon creating a more comprehensive single source of trombone heritage was entitled, "A Historical Background of the Trombone and Its Music" (1967), by Joseph Milford Nicholson (b. 1935). Joseph Nicholson was born in Penoke, Kansas, on August 15, 1935. Raised in a musical family, he learned to play the trombone in the public school bands of his hometown, Fruita, Colorado. Later, Nicholson enrolled at Southwestern Bible Institute (1952-1955) and graduated from Texas Wesleyan College (B.Mus 1957). He earned the MME (1961) from North Texas State University and the D.M.A. (1967) from the Conservatory of Music at the University of Missouri at Kansas City (UMKC). Nicholson taught at Southwestern beginning in 1956, but left in 1960 to teach at Evangel College, Springfield, MO, where he taught until 1991. During his years at Evangel, Nicholson was chair of the Fine Arts Department (1967-1981), the principal trombonist in the Springfield (MO) Symphony (1966-1977), and an active member of the Springfield Brass Quintet (1966-1977). Nicholson pursued his interest in trombone history and literature while studying at UMKC. Because his text summarized into one document the current knowledge of the time about the history and literature of the trombone, Nicholson's work was one of the earliest to appear outside the context of the music dictionaries. Through his writing, teaching, and presentations, Nicholson is thought to have spurred interest among the next generation of trombonists who began to develop a more comprehensive chronicle of the trombone. Nicholson's legacy continues through his influence upon trombonists and the citations in later, more era-specific histories of the instrument."--Abstract from author supplied metadata

The exponential ordering for nonautonomous delay systems with applications to compartmental Nicholson systems
No full textProducción CientíficaThe exponential ordering is exploited in the context of nonautonomous delay
systems, inducing monotone skew-product semiflows under less restrictive conditions
than usual. Some dynamical concepts linked to the order, such as semiequilibria, are
considered for the exponential ordering, with implications for the determination of
the presence of uniform persistence or the existence of global attractors. Also, some
important conclusions on the long-term dynamics and attraction are obtained for
monotone and sublinear delay systems for this ordering. The results are then applied
to almost periodic Nicholson systems and new conditions are given for the existence
of a unique almost periodic positive solution which asymptotically attracts every
other positive solution.The first three authors were partly supported by MICIIN/FEDER project RTI2018- 096523-B-I00 and by Universidad de Valladolid under project PIP-TCESC-2020. The fourth author was partly supported by MICINN/FEDER under projects RTI2018-096523-B-I00 and PGC2018-097565-B-I0
Transposon-associated lincosamide resistance lnu(C) gene identified in Brachyspira hyodysenteriae ST83
No full textTreatment of Swine Dysentery (SD) caused by Brachyspira hyodysenteriae (B. hyodysenteriae) is carried out using antimicrobials such as macrolides, lincosamides and pleuromutilins leading to the selection of resistant strains. Whole genome sequencing of a multidrug-resistant B. hyodysenteriae strain called BH718 belonging to sequence type (ST) 83 revealed the presence of the lincosamide resistance gene lnu(C) on the small 1724-bp transposon MTnSag1. The strain also contains an A to T substitution at position 2058 (A2058T) in the 23S rRNA gene which is known to be associated with macrolide and lincosamide resistance in B. hyodysenteriae. Testing of additional strains showed that those containing lnu(C) exhibited a higher minimal inhibitory concentration (MIC) of lincomycin (MIC ≥ 64 mg/L) compared to strains lacking lnu(C), even if they also harbor the A2058T mutation. Resistance to pleuromutilins could not be explained by the presence of already reported mutations in the 23S rRNA gene and in the ribosomal protein L3. This study shows that B. hyodysenteriae has the ability to acquire mobile genetic elements conferring resistance to antibiotics
Ehecatl Quetzalcoatl vs. Topiltzin Quetzalcoatl of Tollan: a Problem in Mesoamerican Religion and History
No full textThis article by Henry B. Nicholson explores the complex relationship between two key figures in Mesoamerican thought: Ehecatl-Quetzalcoatl, the wind deity, and Topiltzin Quetzalcoatl, the legendary ruler of Tollan. Through a thorough review of pictographic sources, colonial texts, and historical analysis, the author identifies interpretative challenges surrounding the conceptual merging or separation of these figures. The study provides valuable insights into the religious and ideological evolution of ancient Mexico, as well as the symbolic construction of power in theocratic contextsEste artículo, escrito por Henry B. Nicholson, examina la compleja relación entre dos figuras centrales del pensamiento mesoamericano: Ehécatl-Quetzalcóatl, deidad del viento, y Topiltzin Quetzalcóatl, gobernante legendario de Tollan. A través de una cuidadosa revisión de fuentes pictográficas, textos coloniales y análisis históricos, el autor identifica problemas de interpretación en torno a la fusión o separación conceptual de ambas entidades. El estudio aporta claves importantes para comprender la evolución religiosa e ideológica del México antiguo, así como la construcción simbólica del poder en contextos teocráticosInstituto de Investigaciones Históricas, Universidad Nacional Autónoma de Méxic
Crank-Nicholson difference scheme for the system of nonlinear parabolic equations observing epidemic models with general nonlinear incidence rate
No full textIn this work, we study second order Crank-Nicholson difference scheme (DS) for the approximate solution of problem (1). The existence and uniqueness of the theorem on a bounded solution of Crank-Nicholson DS uniformly with respect to time step τ is proved. In practice, theoretical results are presented on four systems of nonlinear parabolic equations to explain how it works on one and multidimensional problems. Numerical results are provided. © 2021 the Author(s), licensee AIMS Press

No full textWe present results from a search for the flavor-changing neutral current decays B --> Kl(+)l(-) and B --> K*l(+)l(-), where l(+)l(-) is either an e(+)e(-) or mu(+)mu(-) pair. The data sample comprises 22.7 x 10(6) Y (4S) --> BB decays collected with the BABAR detector at the PEP-II B Factory. We obtain the 90% C. L. upper limits B (B --> Kl(+)l(-)) K*l(+)l(-)) Ke(+/-) mu(-/+) and B --> K* e(+/-) mu(-/+)

Angular distributions in the decay B -> K*l(+)l(-)
No full textWe use a sample of 384 X 10(6) B (B) over bar events collected with the BABAR detector at the PEP-II e(+)e(-) collider to study angular distributions in the rare decays B -> K(*)l(+)l(-), where l(+)l(-) is either e(+)e(-) or mu(+)mu(-). For low dilepton invariant masses, m(ee) 3.2 GeV/c(2), we measure A(FB) = 0.76(-0.32)(+0.52) +/- 0.07 F-L = 0.71(-0.22)(+0.20) +/- 0.04

Clifford: 409, Aster 17 (BM-000647099). Current name: Felicia fruticosa (L.) G. Nicholson (Asteraceae). Note: Grau (in Mitt. Bot. Staatssamml. München 9: 275. 1973) indicated both 997.6 and 997.7 (LINN) as types. These collections do not form part of a single gathering (so Art. 9.15 does not apply) and Wijnands (Bot. Commelins: 75. 1983) was correct to reject this as an ineffective type choice. Jones & Hiepko appear to have been the first to make an explicit type choice.Published as part of Jarvis, Charlie, 2007, Chapter 7: Linnaean Plant Names and their Types (part A), pp. 252-342 in Order out of Chaos.
