MHNG 2270.056, 2, 21.5 – 23.8 mm SL, same locality and collectors as MHNG 2228.075, 19 March 1985. Diagnosis. Hemigrammus changae differs from most congeners except from H. barrigonae, H. lunatus, H. machadoi, and H. ulreyi by possessing a wide dark horizontal stripe across the eye (vs. eye stripe absent or, when present, vertical). The new species can be additionally distinguished from all congeners, with the exception of Hemigrammus barrigonae, H. boesemani, H. geisleri, H. lunatus, H. machadoi, H. mimus, and H. ulreyi, by presenting a well-defined narrow dark stripe at the basis of the anal fin (vs. absence of dark stripe at the basis of anal fin). It can be distinguished from H. boesemani, H. geisleri, and H. mimus by lacking a blotch on caudal peduncle or any distinct patch of pigmentation on caudal fin (vs. a dark blotch on caudal peduncle or at the base of caudal fin present). Hemigrammus changae can be additionally diagnosed from Hemigrammus geisleri and H. mimus by lacking a pseudotympanum (vs. presence of a conspicuous pseudotympanum). The new species can be diagnosed from H. barrigonae, H. lunatus, and H. machadoi by presenting an oval, horizontally elongated humeral blotch (vs. a diffuse, vertically-elongated humeral blotch in H. barrigonae; a small rounded humeral blotch in H. lunatus; a rectangular, vertically-elongated blotch in H. machadoi). Hemigrammus changae can be distinguished from H. ulreyi by the absence of a patch of dark pigmentation on the basis of anteriormost dorsal-fin rays (vs. presence of a patch of dark pigmentation on the basis of anteriormost dorsal-fin rays). The new species can be additionaly distinguished from H. ulreyi, as well as from H. barrigonae, by lacking a conspicuous midlateral stripe (vs. presence of a conspicuous midlateral stripe). Hemigrammus changae can be additionally diagnosed from H. machadoi by presenting 6–7 gill-rakers on upper branch and 10–12, mode 12, on lower (vs. 4–5, and 9–10, mode 9, respectively), and more vertebrae (34–35 vs. 32–33), and from H. lunatus by presenting a higher number of cusps on maxillary largest tooth (5 vs. 1–3). Description. Morphometric data summarized in Table 1. Body compressed, moderately high; greatest body depth anterior to dorsal-fin origin. Dorsal profile of head slightly convex from tip of snout to anterior naris; straight to gently concave from latter point to tip of supraoccipital spine.

Anal-fin hooks were observed in males of Hemigrammus changae collected in August (MUSM 3927, 1, 23.7 mm SL), December (ZUEC 17027, 4, 22.2–23.6 mm SL; FMNH 138666, 2, 24.0– 24.5 mm SL; MCZ 173322, 1, 23.5 mm SL; CAS 246141, 3, 23.5–24.0 mm SL), or February (INPA 57938, 2, 23.0– 23.1 mm SL; MUSM 22018, 5, 23.3–25.0 mm SL; and MUSM 22040, 2, 23.0– 23.3 mm SL). Anal fin with 7–11 tiny hooks, arranged over the last unbranched ray and anteriormost 3–5 branched fin rays, one pair per ray segment. Pelvic-fin hooks were not observed in any specimens. Larger specimens (equal or above 26.0 mm SL) always lack anal-fin hooks and presumably are all females, which consequently are inferred to grow larger than males (the largest specimen examined with anal-fin hooks has 25.0 mm SL, MUSM 22018). Distribution. Hemigrammus changae is so far known from the río Madre de Dios and from the río Mamoré basins, upper río Madeira basin, in southeastern Peru and Bolivia (Fig. 3). The new species is apparently endemic from the freshwater ecorregion Mamoré-Madre de Dios Piedmont (Abell et al., 2008). Ecological notes. Most localities from where Hemigrammus changae is known are slow-flowing streams at "aguajales" (wetlands dominated by Mauritia flexuosa palms). These streams typically possess black water, a large amount of decayed organic matter, and are typically shallow. The type locality was a former a gold mining area that is in the process of recovery due to the implantation of a private conservation concession. Hemigrammus changae is also recorded from oxbow lakes and, in Bolivia, from lakes and streams at the llanos (seasonally flooded savannahs). The species is sympatric, and in some localities syntopic with Hemigrammus lunatus, but the latter species is more commonly found in floodplain lakes from white water rivers, a type of habitat where H. changae is apparently uncommon. Etymology. The specific name honors the late Fonchii Ingrid Chang Matzunaga, a Peruvian ichthyologist, from Chinese and Japanese ancestry, born on April 30, 1963 in Lima, Peru, who drowned when the boat she was in capsized on August 15, 1999, during an expedition at río Pastaza, Peru. We dedicate to her the new species as a tribute for her considerable contribution in surveying the fishes of her native country, in the relatively little time she was active, which included collecting part of the material herein examined of H. changae. A genitive noun.Published as part of Ota, Rafaela P., Lima, Flávio C.

    Romances contra Hidalgo y Marroquín de Francisco Estrada y Terán

    No full text
    This essay presents two romances of historical character, writings in favour of the State and the Spanish Crown and in opposition to the insurgent movement; in these texts one attacks, especially, the priest Hidalgo and the bullfighter Agustin Morroquin, who was nominated a deputy by the own Hidalgo. The romances were printed in the moment itself in which there were provoked the events of the War of Independence and appeared without author, my search has made possible that now we know the one who was his author: the Licentiate Francisco Estrada y Teran. The essay does the times of introduction and, at the same time, there are checked his literary and historical characteristics; the romances are reproduced, with spelling and punctuation modernized, to the philologic use and with a device of notes of character historically. There treats about the first two of the literary manifestations novohispanas of thematic counterinsurgent and they recover about the celebrations of the bicentenary of the beginning of the heroic Mexican exploit.Este ensayo presenta dos romances de carácter histórico escritos en favor del Estado y la Corona española y en contra del movimiento insurgente. En estos textos se ataca en particular al cura Hidalgo y al torero Agustín Morroquín, quien fue nombrado lugarteniente por el propio Hidalgo. Los romances fueron impresos en el momento mismo en que se suscitaban los acontecimientos de la guerra de Independencia y aparecieron sin firma, mi búsqueda ha hecho posible que ahora sepamos quién fue su autor: el licenciado Francisco Estrada y Terán. El ensayo hace las veces de introducción, y al mismo tiempo, se revisan sus características literarias e históricas; se reproducen los romances, con ortografía y puntuación modernizadas al uso filológico y con un aparato de notas de carácter histórico. Se trata de dos de las primeras manifestaciones literarias novohispanas de temática contrainsurgente y se recuperan a propósito de las celebraciones del bicentenario del inicio de la heroica gesta mexicana

    The Knops blood group antigen erythrocyte polymorphisms have been associated with reduced falciparum malaria-based in vitro rosette formation (putative malaria virulence factor). Having previously identified single-nucleotide polymorphisms (SNPs) in the human complement receptor 1 (CR1/CD35) gene underlying the Knops antithetical antigens Sl1/Sl2 and McC(a)/McC(b), we have now performed genotype comparisons to test associations between these two molecular variants and severe malaria in West African children living in the Gambia. While SNPs associated with Sl:2 and McC(b+) were equally distributed among malaria-infected children with severe malaria and control children not infected with malaria parasites, high allele frequencies for Sl 2 (0.800, 1,365/1,706) and McC(b) (0.385, 658/1706) were observed. Further, when compared to the Sl 1/McC(a) allele observed in all populations, the African Sl 2/McC(b) allele appears to have evolved as a result of positive selection (modified Nei-Gojobori test Ka-Ks/s.e.=1.77, P-valu

    Este artículo aporta al estudio de la crítica de Hilarión Frías y Soto (El Portero del Liceo Hidalgo) sobre la obra de Ángel de Campo Micrós. Analiza la narrativa de éste en la prensa capitalina de fin del siglo XIX, pasando por su filiación al nacionalismo y su necesidad de adaptarse a la nueva estética decadentista; todo esto bajo la luz de algunos conceptos de la sociología literaria de Pierre Bourdieu. A partir de las observaciones que Ángel Rama hace sobre el régimen porfiriano en nuestra capital en La ciudad letrada, también se estudia la obra de Micrós en la Revista Azul, poniendo de relieve su eclecticismo nacionalista y modernista

    Quantum SL(2,R)SL(2,\mathbb{R}) and its irreducible representations

    We define for real qq a unital *-algebra Uq(sl(2,R))U_q(\mathfrak{sl}(2,\mathbb{R})) quantizing the universal enveloping *-algebra of sl(2,R)\mathfrak{sl}(2,\mathbb{R}). The *-algebra Uq(sl(2,R))U_q(\mathfrak{sl}(2,\mathbb{R})) is realized as a *-subalgebra of the Drinfeld double of Uq(su(2))U_q(\mathfrak{su}(2)) and its dual Hopf *-algebra Oq(SU(2))\mathcal{O}_q(SU(2)), generated by the equatorial Podle\'s sphere coideal *-subalgebra Oq(K\SU(2))\mathcal{O}_q(K\backslash SU(2)) of Oq(SU(2))\mathcal{O}_q(SU(2)) and its associated orthogonal coideal *-subalgebra Uq(k)Uq(su(2))U_q(\mathfrak{k}) \subseteq U_q(\mathfrak{su}(2)). We then classify all the irreducible *-representations of Uq(sl(2,R))U_q(\mathfrak{sl}(2,\mathbb{R})).Comment: 22 pages; author accepted manuscrip

    On the sheaf-theoretic SL(2, C) Casson–Lin invariant

    No full text
    We prove that the (τ-weighted, sheaf-theoretic) SL(2, C) Casson–Lin invariant introduced by Manolescu and the first author is generically independent of the parameter τ and additive under connected sums of knots in integral homology 3-spheres. This addresses two questions asked by Manolescu and the first author. Our arguments involve a mix of topology and algebraic geometry, and rely crucially on the fact that the SL(2, C) Casson–Lin invariant admits an alternative interpretation via the theory of Behrend functions.</p

    Candidatus Rhetoricae (or Novus Candidatus).

    No full text
    This little book is a find whatever it finally turns out to be! For now it seems to be a Jesuit collegium text in rhetoric following the Progymnasmata of Aphthonius. If one works from the back of the book, there is an apparently independent 48-page work, Angelus Pacis by Nicolas Caussini (Latinized name), S.J. The rest of the book seems to be a commentary on or presentation of Aphthonius' Progymnasmata in 3 parts covering 435 pages, followed by a T of C and an AI, which is often one page off. Pars II is titled Rhetoricae Praecepta, Pars III De Panegyrico seu Laudatione. Pars I seems to be Apparatus ad Fabulam et Narrationem. Fable is handled on 15-31. After the famous Greek definition of Theion done into Latin ( sermo falsus veritatem effingens ), the author distinguishes rational (human) and moral (animal) fables, with mixed fables including both. He holds (19) that the sense of the fable generally needs to be expressed; otherwise people often miss the point of a fable. His Latin for promythium is praefabulatio, for epimythium affabulatio. Apologus and parabola are identical for him with fabula. After describing the qualities and uses of fables, the author presents some nine fables that exemplify various levels of style, twice telling the same stories on two levels (WL and FC). The last example is of the florid style: The Silkworm and the Spider takes four pages to tell! I found this book sitting in a box of disparate, unmarked, old books. It pays to look!This is a hardbound book (hard cover)Language note: Bilingual: Greek/LatinElzevers

    Searches for New Physics effects in b →sl-sl+ transitions

    No full text
    The dissertation aims at presenting the current situation in the measurements of electroweak penguin diagrams dominated decays: b → sl−l+1 . These decays have been a smoking gun for hunting for New Physics effects over many years, but in the last three years the research on these phenomena has intensified due to new measurements. Enormous progress has been made both on the theoretical and the experimental sides to understand the measured deviations from the current Standard Model predictions, referred to in what follows as “anomalies”. The author of this dissertation has been one of the main authors of the angular analysis of B0→ K∗ 0µ+µ− decay in the LHCb experiment, which has been widely regarded as one of the most important results of the flavour physics sector in recent years. He has proposed a method called “the method of moments” to measure the angular terms of this decay, which he has later successfully applied in the measurement itself. Moreover, he has been the driving force behind the two other important analyses in LHCb: the measurement of the angular distribution and branching ratio of the B0→ K∗ 0 (1430)µ+µ− decay, where again the method of moments has been used to obtain the angular coefficients, and the search for the light scalar particle that can be produced in the b → s transitions and that decays to a dimuon pair. In this case no signal has been observed and the upper limits on the branching fraction have been set, later to be used for constraining the inflaton model. The dissertation is organized as follows: the brief introduction is followed by, the second chapter devoted to a theoretical description of rare B decays, where the effective field theory formalism is introduced. Furthermore, the author discusses the current theoretical problems in calculating the Standard Model predictions for the b → sl−l+ processes. Last but not least, the optimised angular observables that are less dependent on the form factors uncertainness are derived. The third chapter describes the experimental apparatus used in the b → sl−l+ measurements. Special focus is put on the sub-detectors that play an important role in the studies of b → sl−l+ transitions. Chapters 4, 5, 6 are devoted to describing the data analyses performed by the author in the LHCb experiment. In Chapter 7 the global analysis of electroweak penguin decays is presented. This kind of global analysis has become extremely popular in the past few years as it helps to constrain and pin down those New Physics models that are likely to be responsible for the observed anomalies. The author of this monograph is involved in one of the biggest collaborations performing New Physics fits, where he is the convenor of the Flavour Working group. Furthermore, the author presents his own study on separating the long distance effects in the B0→ K∗ 0µ+µ−decay. This is the state of the art way of determining those contributions. The chapter ends with a description of possible New Physics models that can explain the observed discrepancies

    SL(n)\operatorname{SL}(n) contravariant function-valued valuations on polytopes

    We present a complete classification of SL(n)\operatorname{SL}(n) contravariant, C(Rn{o})C(\mathbb{R}^n\setminus\{o\})-valued valuations on polytopes, without any additional assumptions.It extends the previous results of the second author [Int. Math. Res. Not. 2020] which have a good connection with the LpL_p and Orlicz Brunn-Minkowski theory. Additionally, our results deduce a complete classification of SL(n)\operatorname{SL}(n) contravariant symmetric-tensor-valued valuations on polytopes
