Practical gamma scintillometry total count versus spectrometry

Producing 65Zn and 60Co gamma sources for energy and efficiency calibration of gamma spectrometry systems

Precise calibration of energy and efficiency of gamma spectrometry systems for different geometries is very important. In most cases, preparation of these sources for educational and research centers  is very difficult due to high costs and lack of access to the reactor. The purpose of this paper is to explain the procedure for production of calibration sources 65Zn and 60Co using instrumental ...

Constants Count: Practical Improvements to Oblivious RAM

Oblivious RAM (ORAM) is a cryptographic primitive that hides memory access patterns as seen by untrusted storage. This paper proposes Ring ORAM, the most bandwidth-efficient ORAM scheme for the small client storage setting in both theory and practice. Ring ORAM is the first tree-based ORAM whose bandwidth is independent of the ORAM bucket size, a property that unlocks multiple performance impro...

Gamow-Teller strength distribution in the beta-decay of l°°Ag from total-absorption gamma spectrometry

The EC//3+-decay of the odd-odd nucleus l°°Ag was studied by means of total absorption v-ray spectrometry. Most of the Gamow-Teller strength was found to be concentrated at an excitation energy of 5.6 MeV in mopd, the FWHM of this resonance being 1.5 MeV. The measured strength distribution which is interpreted within the BCS approximation as being due to the dominant population of four-quasipar...

Statistical versus Practical Significance

Practical versus Optimal Mechanisms

Designing simple mechanisms with desirable revenue guarantees has become a major research agenda in the economics and computation community. However, few mechanisms have been actually applied in industry. In this paper, we aim to bridge the gap between the “simple versus optimal” theory and practice, and propose a class of parameterized mechanisms, tailored for the sponsored search auction sett...
