The biggest infection events show that the most dangerous viruses propagate via the Internet email systems. We propose a new solution to accelerate the identification of infected computers after an attack by e-mail viruses. Our approach uses trap e-mail addresses secured by a feasible cryptographic technique. The novelty of our work is the introduction of virtual e-mail addresses to identify vi...

Coordination in healthcare networks becomes more and more important to enable integrated care scenarios and to increase quality and efficiency in treatment processes. After identification of shortfalls in existing concepts and solutions a process-oriented approach is introduced which enhances integrated care scenarios by IT-driven coordination of interorganizational treatment processes – the co...

LetM = (M,OM) be a smooth supermanifold with connection ∇ and Batchelor model OM ∼= ΓΛE∗ . From (M,∇) we construct a connection on the total space of the vector bundle E →M . This reduction of∇ is well-defined independently of the isomorphism OM ∼= ΓΛE∗ . It erases information, but however it turns out that the natural identification of supercurves inM (as maps from R1|1 toM) with curves in E r...

As e-government plays an increasingly dominant role in modern public administrative management, its pervasive influence on organizations and individuals is apparent. It is, therefore, timely and relevant to examine e-governance—the fundamental mission of e-government. By adopting a stakeholder perspective, this study approaches the topic of e-governance in e-government from the three critical a...

For some scenarios of vehicle tracking and identification, it is desired that radio-frequency identification (RFID) interrogators can be deployed on roadside lampposts or high poles. In order to meet this requirement, active RFID electronic license plate (e-plate) with a slot-dipole antenna is proposed to provide up-tilted beams. Numerical simulations demonstrate that the proposed e-plate anten...

Between August 1994 and September 1996, 28 glycopeptide-resistant enterococci (GRE) were isolated from 8 infected patients and 11 intestinal carriers hospitalized at the University Hospital of Geneva. Identification to the species was made by both phenotypic (API 20 STREP and Rapid ID 32 STREP systems, and Vitek Gram Positive Identification Card) and genotypic methods using a multiplex PCR assa...

Four naphtho-γ-pyrones (fonsecinones A and C and aurasperones A and E) were identified as potential antibacterial agents against Escherichia coli, extended-spectrum β-lactamase (ESBL)-producing E. coli, Pseudomonas aeruginosa, Enterococcus faecalis, and methicillin-resistant Staphylococcus aureus (MRSA) in an in vitro antibacterial screen of 218 fungal metabolites. Fonsecinone A (2) exhibited t...

Identification of programs for computable functions from their graphs and identification of grammars (r. e. indices) for recursively enumerable languages from positive data are two extensively studied problems in the recursion theoretic framework of inductive inference. In the context of function identification, Freivalds, Kinber, and Wiehagen have shown that only those collections of functions...

This paper presents several statistical methods for topic identification on two kinds of textual data: newspaper articles and e-mails. Five methods are tested on these two corpora: topic unigrams, cache model, TFIDF classifier, topic perplexity, and weighted model. Our work aims to study these methods by confronting them to very different data. This study is very fruitful for our research. Stat...
