Reliability of PCR decontamination systems.

An Efficient Multistrategy DNA Decontamination Procedure of PCR Reagents for Hypersensitive PCR Applications

BACKGROUND PCR amplification of minute quantities of degraded DNA for ancient DNA research, forensic analyses, wildlife studies and ultrasensitive diagnostics is often hampered by contamination problems. The extent of these problems is inversely related to DNA concentration and target fragment size and concern (i) sample contamination, (ii) laboratory surface contamination, (iii) carry-over con...

An Evaluation of the Systems Reliability Using Fuzzy Lifetime Distribution

Uncoordinated pilot decontamination in massive MIMO systems

This work concerns wireless cellular networks applying time division duplexing (TDD) massive multiple-input multiple-output (MIMO) technology. Such systems suffer from pilot contamination during channel estimation, due to the shortage of orthogonal pilot sequences. This paper presents a solution based on pilot sequence hopping, which provides a randomization of the pilot contamination. It is sh...

Contamination and Decontamination in Majority-Based Systems

The dynamics of majority voting has always been of interest in the area of discrete dynamical systems. In recent years, there has been a growing interest on this process also in the distributed computing field, due to its links to fault-tolerance, reliability, and virus disinfection. In fact, local voting mechanisms are often employed in distributed systems and networks as a decision tool for a...

Fuzzy Reliability Optimization Models for Redundant Systems

In this paper, a special class of redundancy optimization problem with fuzzy random variables is presented. In this model, fuzzy random lifetimes are considered as basic parameters and the Er-expected of system lifetime is used as a major type of system performance. Then a redundancy optimization problem is formulated as a binary integer programming model. Furthermore, illustrative numerical ex...
