C15−F15Charge Symmetry and theC14(n,γ)C15Reaction Puzzle

Puzzle Generators and Symmetric Puzzle Layout

We present two abstract models of puzzles, permutation puzzles and cyclic puzzles, which can be modelled as puzzle graphs. Based on these models, we implement two puzzle generators and produce various layouts of the puzzles using graph drawing algorithms. Using these puzzle generators we can create new puzzles. Further, we can create new user interfaces of a puzzle by applying different layout ...

C - 15 F Charge Symmetry and the 14 C n ; 15 C Reaction Puzzle

0031-9007= The low-energy reaction 14C n; 15C provides a rare opportunity to test indirect methods for the determination of neutron capture cross sections by radioactive isotopes versus direct measurements. It is also important for various astrophysical scenarios. Currently, puzzling disagreements exist between the 14C n; 15C cross sections measured directly, determined indirectly, and calculat...

The Equity Premium Puzzle and the Risk-free Rate Puzzle

This paper studies the implications for general equilibnum asset pricing of a class of Kreps-Porteus nonexpected utility preferences characterized by a constant intertemporal elasticity of substitution and a constant, but unrelated, coefficient of relative risk aversion. It is shown that relaxing the parametric restriction on tastes imposed by the time-additive expected utility specification do...
