Large body size for winning and large swords for winning quickly in swordtail males, Xiphophorus helleri

Contestants can either assess their own resource-holding potential relative to their opponent (mutual assessment) or rely solely on the assessment of their own fighting ability (self-assessment). To discriminate between these possibilities, we staged dyadic territorial contests between 'size-matched' male swordtails. These contests consist of a combination of ritualized displays and direct fighting. Although size differences were small, winners were larger than losers and smaller fish tended to be winners only when the size difference was negligible. Body size, however, did not influence contest duration and there was no increase in contest duration with mean body size; thus, there is no support for self-assessment in these animals. We also examined the effects of the sword, which comprises a sexually selected extension used in female choice that reduces swimming efficiency but increases acceleration. The length of the sword (adjusted for body size) did not differ between winners and losers; however, losers conceded earlier if the opponent had a large sword for its body size but this decision was independent of the loser's own sword length. Losers thus assessed the swords of winners, which precludes self-assessment; however, because winners appeared not to assess the swords of losers, this does not fully support the idea of mutual assessment.

Beowulf Hondbona: the Literary Context for Emending Line 1520b

In this article I consider the debate over whether line 1520b ought to be read as the emended “hond sweng” or the scribal “hord swenge.” It is a small point philologically but it raises interesting cultural and literary questions about the attitude of the Beowulf poet to arms and armour, to aggressive and defensive war gear, and to swords in particular. It has widely been assumed that swords are important in Beowulf and yet, the question of what their significance might be has received very little attention. Throughout the poem the hero is plagued by breaking, melting, and failing swords. He borrows, finds, and is given swords but unlike other English and Germanic heroes he is never identified with a single, great sword. I suggest that this is because, ultimately, Beowulf is conceived as a hondbana, a designation which has implications for what kind of a hero he proves to be.

Nilotinib 300mg BID as frontline treatment of CML:Prospective analysis of the Xpert BCR-ABL Monitor system and significance of 3-month molecular response

Sixty patients with early chronic phase CML (ECPCML) received Nilotinib on a phase II study which included a comparison of the Xpert BCR-ABL Monitor™ PCR system with standardized (IS) BCR-ABL1 real-time quantitative PCR (RQ-PCR). 88% patients achieved MMR with 45% achieving MR4.5. At 3 months BCR-ABL1/ABL1 IS >1% and

Algunas consideraciones acerca de la espada de Guadalajara: ¿Un excepcional depósito desarticulado del Bronce Medio de la Meseta?

An exceptional gold-hilted sword, presumably from the province of Guadalajara, which today is kept in Madrid at the National Museum of Archaeology, has usually been treated as an isolated find. However, early references to this piece, when it was kept in the Rodriguez Bauza collection, would seem to indicate that it may have formed part of a hoard together with two other swords, one of which apparently can be associated with fragments of a second hilt-cover of gold sheet, acquired originally with the complete sword. Furthermore, during re-restoration of the first sword, traces left on its surface from at least two different hilts, demonstrated that the current gold-covered design has to be considered a secondary modification. While some Mycenean influence in the design of these weapons and their ornaments cannot be ruled out, for technical reasons a production on the Meseta at least of the gold sheets seems more likely than in the Southeast, where the ElArgarculture is usually more readily associated with the diffusion of Aegean elements.
