USING PROMPT NEUTRON DECAY CONSTANT MEASUREMENTS TO OBTAIN ADDITIONAL KINETICS INFORMATION

Precision Measurements in Neutron Decay

Free neutrons decay with a mean lifetime τn of about 15 minutes in electron, proton, and electron anti-neutrino: n → e p νe. The maximal kinetic energy of the electron is Emax(e) = 782 keV. For the proton, Emax(p) = 780 eV is three orders of magnitude smaller. Neutron decay – involving all particles of the first generation – constitutes an ideally suited laboratory to do particle physics at ver...

Using Incentives to Obtain Truthful Information

There are many scenarios where we would like agents to report their observations or expertise in a truthful way. Game-theoretic principles can be used to provide incentives to do so. I survey several approaches to eliciting truthful information, in particular scoring rules, peer prediction methods and opinion polls, and discuss possible applications.

Using Defeasible Information to Obtain Coherence

We consider the problem of obtaining coherence in a propositional knowledge base using techniques from Belief Change. Our motivation comes from the field of formal ontologies where coherence is interpreted to mean that a concept name has to be satisfiable. In the propositional case we consider here, this translates to a propositional formula being satisfiable. We define belief change operators ...

A novel method to obtain proximal plethysmographic information from distal measurements using the impedance plethysmogram

We present a novel method to detect proximal volume changes based on the impedance plethysmogram (IPG) measured from limb to limb with two electrode pairs symmetrically placed at distal areas of the upper or the lower limbs. Since the measurement is sensitive to changes along the whole current path, this method allows us to detect changes in arteries that are more proximal to the torso than the...
