The exchange of massless neutrinos between heavy fermions (e.g. e, p, n) gives rise to a long-range 2-body force. It is shown that the analogous many-body force can lead to an unphysically large energy density in white dwarfs and neutron stars. To reduce the energy density to a physically acceptable value, the neutrino must have a minimum mass, which is approximately 0.4 eV/c. Some recent quest...

statistical errors are common in scientific literature and about 50% of the published articles have at least one error. the assumption of normality needs to be checked for many statistical procedures, namely parametric tests, because their validity depends on it. the aim of this commentary is to overview checking for normality in statistical analysis using spss.

DEFINITION Publish/subscribe (pub/sub) is a many-to-many communication model that directs the flow of messages from senders to receivers based on receivers’ data interests. In this model, publishers (i.e., senders) generate messages without knowing their receivers; subscribers (who are potential receivers) express their data interests, and are subsequently notified of the messages from a variet...

Addressing knowledge communication with shared databases, this chapter focuses on an asynchronous, many-to-many type of computer-mediated communication (CMC). After an introduction, which characterizes this kind of CMC and provides definitions, various aspects are discussed that influence people’s behavior in knowledge communication with shared databases. This presentation focuses on psychologi...

We consider the many-to-many two-sided matching problem under a stringent domain restriction on preferences called the max-min criterion. We show that, even under this restriction, there is no stable mechanism that is weakly Pareto efficient, strategy-proof, or monotonic (i.e. respects improvements) for agents on one side of the market. These results imply in particular that three of the main r...
