In ‘Corroborating Testimony, Probability and Surprise’, Erik J. Olsson ascribes to L. Jonathan Cohen the claims that if two witnesses provide us with the same information, then the less probable the information is, the more confident we may be that the information is true (C), and the stronger the information is corroborated (C*). We question whether Cohen intends anything like claims (C) and (...

The scandal of medical witnesses being retained on opposite sides in courts of law and crivin" what looks like partisan evidence is often the subject of remark and sneer, and it is mooted that if medical men cited as witnesses by opposing litigants were to meet in consultation before thecase came into court and were to arrive at some sort of agreement regarding the fact and the opinion founded ...

We derive a set of algebraic equations, the so-called multipartite separability eigenvalue equations. Based on their solutions, we introduce a universal method for the construction of multipartite entanglement witnesses. We witness multipartite entanglement of 10(3) coupled quantum oscillators, by solving our basic equations analytically. This clearly demonstrates the feasibility of our method ...

If gifts are reciprocated in the future, intra-household distribution of resources will depend on premarital gifts such as dowry, bride-price and parents’ gifts to a child such as schooling and nurturing. If such social norms of reciprocity exist, parental income effects on their child’s human capital will be asymmetric, and the effect will depend on the amount of intra-household transfers made...

Dimension witnesses allow one to test the dimension of an unknown physical system in a device-independent manner, that is, without placing assumptions about the functioning of the devices used in the experiment. Here we present simple and general dimension witnesses for quantum systems of arbitrary Hilbert space dimension. Our approach is deeply connected to the problem of quantum state discrim...

In England and Wales, in accordance with the adversarial principle of orality, witnesses in criminal proceedings are generally required to give evidence ‘live’ in open court. It is, nevertheless, now widely accepted that this obligation can place onerous demands on witnesses and militates against receipt of the best evidence potentially available in some cases. For victims of rape, the process ...

The problem of demonstrating entanglement is central to quantum information processing applications. Resorting to standard entanglement witnesses requires one to perfectly trust the implementation of the measurements to be performed on the entangled state, which may be an unjustified assumption. Inspired by the recent work of F. Buscemi [Phys. Rev. Lett. 108, 200401 (2012)], we introduce the co...
