Ratio of kaon and pion leptonic decay constants with N f = 2 + 1 + 1 Wilson-clover twisted-mass fermions
No full textWe present a determination of the ratio of kaon and pion leptonic decay constants in isosymmetric QCD (ISOQCD), fK/fπ, making use of the gauge ensembles produced by the Extended Twisted Mass Collaboration with Nf = 2 + 1 + 1 flavors of Wilson-clover twisted-mass quarks, including configurations close to the physical point for all dynamical flavors. The simulations are carried out at
three values of the lattice spacing ranging from ∼0.068 to ∼0.092 fm with linear lattice size up to L ∼ 5.5 fm. The scale is set by the particle data group (PDG) value of the pion decay constant, fISOQCD π = 130.4(2) MeV, at the ISOQCD pion point, MISOQCD π = 135.0(2) MeV, obtaining for the gradient-flow scales the values w0 = 0.17383(63) fm, .....t0 = 0.14436(61) fm and t0/w0 =
0.11969(62) fm. The data are analyzed within the framework of SU(2) chiral perturbation theory without resorting to the use of renormalized quark masses. At the ISOQCD kaon point MISOQCD K = 494.2(4) MeV we get (fK/fπ)ISOQCD = 1.1995(44), where the error includes both statistical and systematic uncertainties. Implications for the Cabibbo-Kobayashi-Maskawa matrix element jVusj and for the first-row Cabibbo-Kobayashi-Maskawa unitarity are discussed
Wechselrede. Rhetorische Anmerkungen zur europäischen Brieftheorie
No full textDer briefliche Dialog berücksichtigt Regeln, deren Ursprünge in den Theorien der Rhetorik liegen, welche ihrerseits Voraussetzung der individuellen Freiheit eines jeden Briefschreibers sind.Seit der Antike sind die Briefrhetorik und die ihr zugrunde liegende Wechselrede Objekt gattungstheoretischer Reflexionen. Schon Aristoteles untersucht die briefliche Wechselrede und verleiht ihr eine (staats)-bürgerliche Dimension. Jeder Bürger kann zugleich Autor und Leser sein und berücksichtigt seine Adressaten. Cicero verlängert diese Reflexion und führt zugleich eine Unterscheidung zwischen informativen, freundschaftlichen bzw. familiären und politischen Briefen ein. Diese Dreiteilung existiert bis ins Mittelalter und wird in Hinblick auf die jeweiligen Adressaten präzisiert.Die Variationen der folgenden Jahrhunderte betreffen vor allem den intimen Brief, der zwischen Ordnung und Phantasie, Spontanität und Anwendung der Regeln schwankt. Noch Gellert verwendet das antike Modell, bezieht sich auf Cicero und Quintilian und behält das Prinzip der Wechselrede bei. Er wendet sich jedoch von der strengen imitatio zu Gunsten der Stilistik ab. Die Mechanismen der Sprache (Philologie) und deren kommunikative Dimension (Geselligkeit) treten in den Vordergrund. Briefliche Kommunikation wird zur Vermittlung der Affekte unter Einbeziehung der räumlichen Distanz.Les épistoliers, hommes et femmes de dialogue, observent des conventions puisant leur origine dans des théories rhétoriques qui servirent de prémices à la liberté individuelle. Depuis l’Antiquité, la rhétorique épistolaire et le dialogisme qui y préside font l’objet des réflexions des théoriciens. L’article en présente les strates successives. Aristote déjà analyse le dialogisme épistolaire et lui confère une tournure civique, chaque citoyen ayant vocation à être à la fois auteur et lecteur puisqu’il prend en compte son destinataire. Cicéron prolonge la réflexion en opérant une distinction entre lettre informative, confidence amicale et familière, et démonstration à finalité politique. Cette tripartition sera conservée au Moyen Âge et alors ajustée au statut social du destinataire. Les variantes ultérieures concernent surtout la lettre intime, qui oscille entre ordre et fantaisie, respect des règles et spontanéité. Le modèle antique reste celui de Gellert qui conserve le principe du dialogisme mais abandonne une imitatio servile et privilégie la stylistique. Cela illustre le fonctionnement même de la langue (philologie) et sa vocation à permettre la communication entre les hommes (sociabilité). Converser par lettre incitera à travailler à transposer ses affects et à exploiter les ressources de l’éloignement du destinataire.Men and women of dialogue observe conventions that owe their origins to rhetorical theories, the latter serving as a premise for the individual freedom of every letter writer. Since ancient times, epistolary rhetoric and the dialogism that presides over it have been the subject of much debate by theorists. This article presents the successive strata. Aristotle had already analysed epistolary dialogism and provided it with a civic twist: that every citizen aspires to be both author and reader since he takes the recipient into account. Cicero expands on this idea by making a distinction between an informative letter, confiding in family or a friend, and communications for political ends. This tripartite division was to last into the Middle Ages and then be adapted to the recipient’s social status. The variants that arrive in subsequent centuries are mainly concerned with private letters, which oscillate between propriety and fantasy, respect for the rules and spontaneity. The model from Antiquity remains that of Gellert, who retains the principle of dialogism. But Gellert abandons a servile imitatio and promotes another aspect of rhetoric: style. This reflects the actual functioning of language (philology) and its purpose in enabling communication between people (sociability). Conversing by letter encourages an ever-greater attempt to translate affections and to exploit the resources of the physical distance of the recipient
Rhetorica movet. Acerca de la genealogía retórica del pathos
No full textThe history of ëpathosë since the 18th century is a history full of misconceptions and misinterpretations. This essay is an attempt to give a secure ground to the current discussion about the meaning of pathos by examining the rhetorical roots of the concept. Therefore, the author is taking a look at Aristotle’s fundamental definition of ëpathosí and his threefold scheme of types of appeal. Moreover Cicero’s modification of Aristotle’s concept is scrutinised. Emphasising Cicero’s importance for the discussion against the tendency to consider Longinus as the most substantial authority on ëpathosí opens a new perspective on the issue. As a result it becomes clear that ëpathosí is one means of persuasion among others and that the misuse of pathos in the 19th and 20th century is a result of ignoring the rhetorical insights into this mean of persuasion
Effects of Combined Plyometric and Sprint Training on Sprint Performance in Youth Soccer Players
No full textBackground/Objectives: Plyometrics is a widely used method to enhance the physical performance of athletes. Studies have demonstrated that the effectiveness of plyometrics increases when combined with other training methods. This study aims to determine whether the direct combination of plyometric and sprint training improves linear sprint speed and change-of-direction speed in youth soccer players. Methods: Twenty-eight male youth soccer players were randomly assigned to an intervention group (INT, n = 14, 12.9 ± 0.4 years) and a control group (CON, n = 14, 12.9 ± 0.7 years). The INT group performed two sessions per week, each including nine drop jumps, followed by a hurdle jump and one sprint. The CON group only performed nine sprints without any jumps. Both groups continued their regular soccer training over the 20-week intervention period. Pre- and post-intervention tests included 5 m, 10 m, and 30 m linear sprints and a modified agility t-test for change-of-direction speed. Results: Largest improvements were observed in the INT group (5 m = 6.7%, 10 m = 4.8%, 30 m = 2.7%, change-of-direction speed = 3.6%, 3.1%). A significant difference between the groups was noted for the 10 m sprint distance (p = 0.02). Furthermore, moderate to large correlations between linear sprint speed and change-of-direction speed were found in both groups (r = 0.33–0.82). Conclusions: Results suggest that the direct combination of plyometric training and sprint training over a 20-week period can improve both linear sprint speed and change-of-direction speed in youth soccer players, thus enhancing physical performance
Gradient-flow scale setting with Wilson-clover twisted-mass fermions
No full textWe present a determination of the gradient flow scales w0 , t0‾‾√
and t0/w0 in isosymmetric QCD, making use of the gauge ensembles produced by the Extended Twisted Mass Collaboration (ETMC) with Nf=2+1+1
flavours of Wilson-clover twisted-mass quarks including configurations close to the physical point for all dynamical flavours. The simulations are carried out at three values of the lattice spacing and the scale is set through the PDG value of the pion decay constant, yielding w0=0.17383(63) fm, t0‾‾√=0.14436(61) fm and t0/w0=0.11969(62)
fm. Finally, fixing the kaon mass to its isosymmetric value, we determine the ratio of the kaon and pion leptonic decay constants to be fK/fπ=1.1995(44)
