Coupon Recalculation for the GPS Authentication Scheme
Equipping branded goods with RFID tags is an effective measure to fight the growing black market of counterfeit products. Asymmetric cryptography is the technology of choice to achieve strong authentication but suffers from its ample demand of area and power resources. The GPS authentication scheme showed that a coupon-based approach can cope with the limited resources of passive RFID tags. Thi...
متن کاملCMAJ's impact factor: room for recalculation.
he creation of citation indexes brought symmetry to the study of scientific developments. Whereas the reference lists appended to published articles allow scientific advances to be tracked backward to their earlier conceptual origins, a citation index allows one to follow the career of scientific papers forward to establish their role in subsequent progress. The indexing of citations therefore ...
متن کاملRecalculation of the calcium requirement of adult men.
BACKGROUND There is uncertainty about the calcium requirement with particular respect to age and sex differences and the calculation of skin calcium losses. OBJECTIVE We calculated the calcium requirement of adult men from a homogenous set of calcium balances and a robust estimate of calcium loss through the skin. DESIGN We reviewed available high-quality published calcium balances in men a...
متن کاملRecalculation of Proton Compton Scattering in Perturbative QCD
At very high energy and wide angles, Compton scattering on the proton (γp → γp) is described by perturbative QCD. The perturbative QCD calculation has been performed several times previously, at leading twist and at leading order in αs, with mutually inconsistent results, even when the same light-cone distribution amplitudes have been employed. We have recalculated the helicity amplitudes for t...
متن کاملAn Interim Sample Size Recalculation for Observational Studies
Interim sample size re-estimation (SSR) often affects the Type I and II error rates. We propose and investigate a method based on resampling the whole study design at the interim analysis. This resampling starts with SSR at the observed interim analysis values of nuisance parameters and finishes with the decision to accept or reject the null hypothesis. The proposed approach finds a new critica...
