Gabriel Guerrero Trío, trío de jazz (Colombia / Estados unidos)
No full textConcierto interpretado por el trío de jazz Gabriel Guerrero Trío. Guerrero quien hoy ha alcanzado un estatus importante en el ámbito del jazz en Nueva York. Su notable ascenso, huelga decirlo, discreto y pausado, se ha materializado con su trío, en sus colaboraciones aliado del titán Jerry Bergonzi, de Bruce Gertz y de Danilo Pérez, así como en sus proyectos junto a Matana Roberts y Dan Blake.
En contraste con su personalidad tranquila y reservada, el estilo de Gabriel Guerrero es enérgico. Esta noche, en compañía de dos músicos excepcionales como el contrabajista Will Slater y el baterista Richie Barshay, lo que se presenció fue una explosión de telepatía y sutileza
Impact parameter representation of the leading proton spectrum in the diffractive region
No full textRecent experiment indicates that there is no limiting value for the pion invariant inclusive cross section at x=0 at the highest energies reached by the CERN intersecting storage rings. The author first notes that a recently proposed integral representation of the leading proton spectrum is physically equivalent to representing this spectrum in terms of very narrow multiplicity distributions from each initial impact parameter, with a single factorizable function for the average multiplicity at any impact parameter b, (n(s, b/R(s)))=N(s)n(b/R(s)). He then observes that, in this approach, the explicit form for the scaled part of the spectrum for mod x mod <0.97 and p/sub T/ approximately 0 depends essentially upon the assumed asymptotic form for the growth of average multiplicity with energy s. The data do not exclude the empirical possibility of N(s varies as s/sup epsilon /, epsilon <1/4. (19 refs)
Trente ans après, que reste-t-il du modèle d'azilianisation proposé au Morin par F. Bordes et D. de Sonneville-Bordes ?

At the end of the 1970's F. Bordes and D. de Sonneville Bordes proposed the progressive Azilianisation model for Tardiglacial human populations in Dordogne Valley based on the sites of Morin and Gare-de-Couze. More recent excavations of key series such as Pont d'Ambon by Guy Cé lé rier or Bois Ragot by Andre Chollet contrasted with this paradigm by characterizing an internal Azilian phasing with no Magdalenian elements. As part of the ANR Magdatis project, we reassessed the emblematic series of Morin in order to test the model advanced by F. Bordes and D. de Sonneville-Bordes in 1979. Abri Morin (Gironde, France) was excavated by Deffarge at the end of the 1950s. The site stratigraphy proposed by Deffarge consists of two main units (A and B). The lower unit B is divided into two levels, BII and BI. Unit A is divided into four levels (AIV at the base to AI at the top). The site yielded a large collection of lithic objects attributed to the Upper and Final Magdalenian (Magdalenian V and VI), as well as many faunal remains (Delpech, 1983), a large quantity of worked bone and antler (Deffarge et al. 1974 a-b) and/or engraved objects (Deffarge et al. 1975; Guy 1993; Paillet and Man-Estier 2014). Prior to our work, only one radiocarbon date was available (Delibrias et al. 1974; Delibrias et Evin 1974). This date (Gif-2105 10 480 ± 200 years BP) appeared to be very recent in comparison to the chronology of archaeological complexes related to the end of the Magdalenian. The reassessment of the lithic material focuses on the armatures. More than 2,000 remains were studied but our analysis is limited to the distribution of five morphotypes in the stratigraphic sequence proposed by Deffarge (Figure 2). Unit B can be attributed to an early phase of the Upper Magdalenian (Figure 4), but unit A contains unprecedented morphotype associations, comprising typically Magdalenian elements (shouldered point, Laugerie Basse type point) with elements characterizing the early Azilian (backed bi-point), the recent Azilian (backed point with tapered base) and the Laborian (backed Malaurie type point). The faunal remains were studied by Delpech (1983) and are mainly composed of reindeer remains associated with Bovine (Bison and/or Aurochs), horse, red deer, and to a lesser extent roe deer and wild boar remains. Avian remains are abundant and diversified (Mourer-Chauvire 1975; Delpech 1983; Gourichon 1994), with a predominance of snowy owl remains. The reassessment of the faunal material resulted in the identification of more than 5,000 remains (Table 1). The proportion of the different taxa is not significantly different from previous publications. Three additional taxa were identified from several remains. These are the dog (Canis familiaris, Boudadi-Maligne et al. 2012), and in lesser proportions, the mammoth and the chamois. Refits were carried out on the faunal material. Most of the associations were from objects from the same level but some of them concern objects found in different levels and in both units (A and B, Figures 5 and 6). In the light of these results, twenty-two faunal remains of known stratigraphic provenance were radiocarbon dated (Table 2). These dates enabled us to test the stratigraphy proposed by Deffarge, but also to document the different problems linked to the appearance or disappearance of different taxa from the region (Szmidt et al. 2009; Boudadi-Maligne et al. 2012; Costamagno et al. 2016), or the dates of the different technocomplexes from the end of the Tardiglacial (Barshay-Szmidt et al. 2016), or the evolution of armature elements made of antler (Pe tillon 2016). The dating results were calibrated with the OxCal software, version 4.3.2 (Bronk Ramsey 2009) with the IntCal13 curve (Reimer et al. 2013) (Figure 7). The cross-analysis of the dates obtained in relation to the stratigraphy proposed by Deffarge reveals numerous discrepancies. The organization of the dates by chronological order is not consistent with the stratigraphic order of the Deffarge levels (figure 7). However, two units can be observed. The first comprises dates between 16 ka calBP and 14 ka calBP. The second comprises four dates obtained on a barbed Azilian type point ("flat harpoon": Deffarge et al., 1974b, Fig. 6, n° 8), a rabbit remain and two wild boar remains. In comparison with the corpus of dates from the different technocomplexes from the end of the Paleolithic (Barshay-Szmidt et al. 2016; Fat Cheung et al. 2014; Langlais et al. 2012, 2014), these four dates can be excluded from what is usually found during the Upper Magdalenian. They correspond more to the early Azilian (wild rabbit), the recent Azilian (wild boar) and the Laborian (barbed Aziloid type point). These results imply that the Morin stratigraphy was not limited to an occupation by the last Magdalenians and must have been much more complex than previously thought. It is very probable that the site was occupied not only by the last Magdalenians, but also during an early and recent phase of the Azilian, and again by Laborian groups. We thus refute the Azilianization model proposed by Bordes and de Sonneville-Bordes and we support hypotheses of gradual evolution brought to light at well studied sequences such as Pont d'Ambon du Bois Ragot, Murat or Rochereil

Translation of humour with special reference to the cartoons in 'Leman' and other popular weekly humour magazines of Turkey
No full textIn this dissertation, the various strategies of humour translation have
been analysed by taking various cartoons with speech bubbles from the popular
Turkish humour weekly magazine Leman and other similar publications.
Generally considered as an extremely problematic, sometimes next to impossible,
task within the translation studies, humour translation requires and deserves
special attention since, as it was explained in the related sections, it may unite or
separate people within the context of one single joke. As we also have stated elsewhere
in the text, the description of both humour and translation, as two
separate concepts, are not available in certain and decisive terms. This is
especially true for the concept of humour which also covers the areas of laughter,
jokes, wit, satire, irony and many others which are all interchangeable with each
other. This fact makes an all-round definition very difficult. We also tried to
show that, the visual humour or the visual aspect of humour could be a valuable
asset for a foreign recipient who genuinely wishing to understand humour
products from a different and remote culture. We wanted to show, and to some
extent share, that the cartoons, provided they are not strictly political or crammed
with regional issues and accents, could be fathomed by an outsider with the help
of a decent translation and an adequate amount of contextual and cultural
background information. We have assumed, from the very beginning of this
project, that the contemporary Turkish humour, particularly cartoons that are
represented in Leman and other similar publications, was interesting enough to
become a dissertation subject, particularly those with stock types or characters
since they have the potential of becoming snapshots of a country which is still considered as alien (or other) by the West. As far as this writer concerned, the
main points of interest concerning Turkey by the British public could roughly be
summarised in two points: a bargain trip to the seaside during the summer season
and some occasional football matches Manchester United plays against Turkish
teams in Istanbul. Especially the latter always attracts heavy press coverage
during and after a match. We wanted to show that there are other cultural aspects
exist in Turkey as well and such aspects could be transferred to other cultures by
ways of translation. The material we have chosen is both visual and prose at the
same time and although they function as a unity, they also complement each other.
It is proposed that, although a perfect translation is always a desirable concept in
almost every field, the translation of humour is possible within certain
frameworks. The visual side of cartoons, as in situation comedies, contributes
immensely to the comprehension of the message, which should be considered as
the most important feature of the joke. To this end, a variety of cartoons are
selected from both Lenicyn and other similar humour weeklies and translated with
an adequate amount of background and contextual information that provided
beforehand. This background information also includes, as far as the material in
question permits, a close analysis of the language and the subject matter. To
provide a better insight for the reader, a summary of Turkish humour and humour
magazines are added alongside a section on the issue of humour itself

Measurement of Charmless Hadronic Two-Body Rare B Meson Decays and Evidence of Direct CP Violation in B -> K+pi- at Belle
No full text基於Belle偵測器所收集到253/fb的資料，我們量測了B介子至不含魅夸克的強子之稀有二體衰變，其中包含了K與π介子兩種強子。在這些衰變模式中，測量了它們衰變分支比以及直接電荷宇稱的不對稱性。基於3.9個標準差，我們得到了Ｂ介子衰變至Ｋ介子與π介子的直接電荷宇稱對稱破壞之證據。同時，以5.8個標準差的信心水準，我們觀測到了Ｂ介子衰變至兩個中性π介子的衰變模式。With integrated luminosity 253/fb data acquired at Belle,
we have studied two body charmless hadronic B-> h h decay modes, where h stands for charged or neutral K/pi mesons.
Among these modes, we have measured the branching fractions and charge asymmetries. The evidence of charge asymmetry for B^0 -> K^+pi^- is found with 3.9 sigma and the branching
fraction of B^0 -> pi^0 pi^0 is observed with 5.8 sigma standard deviation from zero.{1}Introduction{1}
