Spectroscopy of neutron-rich nuclei produced by multinucleon transfer reactions at KISS by Watanabe Yutaka, Hirayama Yoshikazu, Mukai Momo, Niwase Toshitaka, Schury Peter, Rosenbusch Marco, Ishiyama Hironobu, Jeong Sun-Chan, Miyatake Hiroari, Wada Michiharu, Kimura Sota, Iimura Shun, Moon Jun Young, Hashimoto Takashi, Taniguchi Akihiro

“…Due to the lack of experimental nuclear data in the relevant extremely neutron-rich region, especially near and above N = 126, the predictions of theoretical nuclear models are crucial for simulating r-process nucleosynthesis. Experimental studies of the properties and structures of neutron-rich nuclei from near the β stability line up to the r-process path provide important inputs to these theoretical models, improving the accuracy of predictions for the nuclear properties involved in the rprocess. …”

Extensive composable entropy for the analysis of cosmological data by Constantino Tsallis, Henrik Jeldtoft Jensen

“…An entropy is composable if it satisfies that the entropy SA of a system A=B×C consisting of two statistically independent parts B and C is given in a consistent way as SA=Φ(SB,SC) where the composition function Φ(x,y) is obtained from group-theory.We further show that (α,γ)=(1,2/3) satisfactorily agrees with cosmological data measuring neutrinos, Big Bang nucleosynthesis and the relic abundance of cold dark matter particles, as well as dynamical and geometrical cosmological data sets.…”
