Research on leak monitoring of the primary circuit of a pressurized water reactor based on the 13N coincidence method [PDF]
To assess the characteristics of 13N decay, a monitoring method of the primary loop leakage rate based on the γ-γ coincidence method was proposed. In this work, sampling and measurement devices were designed, in which NaI (Tl) crystals were used

SmartTrack: efficient predictive race detection [PDF]
Widely used data race detectors, including the state-of-the-art FastTrack algorithm, incur performance costs that are acceptable for regular in-house testing, but miss races detectable from the analyzed execution. Predictive analyses detect more data races in an analyzed execution than FastTrack detects, but at significantly higher performance cost ...

BELL'S INEQUALITIES DETECT EFFICIENT ENTANGLEMENT [PDF]
We review the status of Bell's inequalities in quantum information, stressing mainly the links with quantum key distribution and distillation of entanglement. We also prove that for all the eavesdropping attacks using one qubit, and for a family of attacks of two qubits, acting on half of a maximally entangled state of two qubits, the violation of a ...

A mathematical model of semiconductor detector gamma-efficiency calibration for rectangular cuboid (brick-shape) sources [PDF]
Rectangular cuboid (rectangular parallelepiped), i. e., brick-shape sources are not really common in general gamma-spectrometry practice with semiconductor detectors, where axially symmetrical sources prevail.
