Optomechanical systems open new possibilities in fundamental research at the interface between quantum information and gravity. Recently, an ambitious experimental proposal was suggested by Bose et al. [S. Bose, A. Mazumdar, G. W. Morley, H. Ulbricht, M. Toro\ifmmode \check{s}\else \v{s}\fi{}, Paternostro, Geraci, P. F. Barker, S. Kim, Milburn, Phys. Rev. Lett. 119, 240401 (2017)] to measure en...

Confident witnesses are deemed more credible than unconfident ones, and accurate witnesses are deemed more credible than inaccurate ones. But are those effects independent? Two experiments show that errors in testimony damage the overall credibility of witnesses who were confident about the erroneous testimony more than that of witnesses who were not confident about it. Furthermore, after makin...

The random 3-satisfiability (3-SAT) problem is in the unsatisfiable (UNSAT) phase when the clause density α exceeds a critical value α(s)≈4.267. Rigorously proving the unsatisfiability of a given large 3-SAT instance is, however, extremely difficult. In this paper we apply the mean-field theory of statistical physics to the unsatisfiability problem, and show that a reduction to 3-XORSAT, which ...

According to law enforcement, many witnesses are intoxicated either at the time of the crime, the interview, or both (Evans et al., Public Policy Law 15(3):194-221, 2009). However, no study to date has examined whether intoxicated witnesses' recall is different from sober witnesses' and whether they are more vulnerable to misinformation using an ecologically valid experimental design. Intoxicat...

Subjects of both sexes individually witnessed the staged theft of a calculator. The 127 witnesses were then given the opportunity to identify the thief from a six-person picture array; from this sample, 24 accurate-identification witnesses and 18 inaccurate-identification witnesses were cross-examined with either leading or nonleading questions. Jurors were unable to distinguish accurate from i...
