This paper reports the purification and the properties of a thioredoxin from the fungus Aspergillus nidulans. This thioredoxin is an acidic protein which exhibits an unusual fluorescence emission spectrum, characterized by a high contribution of tyrosine residues. Thioredoxin from A. nidulans cannot serve as a substrate for Escherichia coli thioredoxin(More)
This paper proposes to investigate the impact of the channel model for authentication systems based on codes that are corrupted by a physically unclonable noise such as the one emitted by a printing process. The core of such a system is the comparison for the receiver between an original binary code, an original corrupted code and a copy of the original(More)
Due to demographic and economic growth in recent developing countries such as Viet Nam, traffic activities increase continuously and the problem of traffic management is urgently required. Consequently, the complexity of collecting traffic data as well as the traffic coordination carried over a control center are exponential. An Intelligent Transportation(More)
Matrix assisted laser desorption mass spectrometry provides a very fast and efficient way to check protein sequences by the analysis of whole proteolytic digests. This method has been applied to the sequence verification of E. coli isoleucyl tRNA synthetase, for which two different sequences are found in data banks. The result of this investigation clearly(More)
In this paper we propose to cast the problem of authentication of printed documents using binary codes into an optimization game between the legitimate source and the opponent, each player tries to select the best print and scan channel to minimize/maximize his authentication performance. It is possible to solve this game by considering accurate(More)
This paper combines the principles of statistical estimation and hypothesis testing to analyze the impact of parameter estimation on an authentication system based on graphical codes. The studied authentication system uses the fact that a code, once printed, undergoes a stochastic and non invertible alteration. A statistical test applies a likelihood ratio(More)
