The open cluster M67 has solar metallicity and an age of about 4 Gyr. The turn-off mass is close to the minimum mass for which solar metallicity stars develop a convective core during main sequence evolution as a result of the development of hydrogen burning through the CNO-cycle. The morphology of the color-magnitude-diagram (CMD) of M67 around the turn-off shows a clear hook-like feature, dir...

The cross section of the process e+e− → ηγ has been measured in the 600-1380 MeV c.m. energy range with the CMD-2 detector. The following branching ratios have been determined: B(ρ → ηγ) = (3.28 ± 0.37 ± 0.23) · 10 , B(ω → ηγ) = (5.10 ± 0.72 ± 0.34) · 10 , B(φ → ηγ) = (1.287 ± 0.013 ± 0.063) · 10 . Evidence for the ρ(1450) → ηγ decay has been obtained for the first time. Budker Institute of Nuc...

Recently, several philosophers have proposed fictionalist accounts of truthtalk, as a means for resolving the semantic pathology that the Liar Paradox appears to present. These alethic fictionalists aim to vindicate truth-talk as a kind of as if discourse, while rejecting that the talk attributes any real property of truth. Liggins (Analysis 74:566–574, 2014) has recently critically assessed on...
