In 1978, Bollobás and Eldridge [5] made the following two conjectures. (C1) There exists an absolute constant c > 0 such that, if k is a positive integer and G1 and G2 are graphs of order n such that ∆(G1),∆(G2) n− k and e(G1), e(G2) ckn, then the graphs G1 and G2 pack. (C2) For all 0 < α < 1/2 and 0 < c < √ 1/8, there exists an n0 = n0(α, c) such that, if G1 and G2 are graphs of order n > n0 s...

The Business Process Modelling Notation (BPMN) and the Event-driven Process Chain (EPC) are both frequently used modelling languages to create business process models. While there is a well-defined standard for BPMN, such a standard is missing for EPC. As a standard would be beneficial to improve interoperability among different vendors, this paper aims at providing the means for future EPC sta...

23 Background: Early phase clinical trials usually include patients (pts) with advanced disease who have failed to standard therapies. palliative care (EPC) for these pts has shown improve quality of life and even survival. Pallia 10 score (from 1 10) is a tool developed by the French Palliative Care Society identify best time introduce care. Methods: We assessed other prognostic factors (age, ...

The term "Internet of Things (IoT)" expresses a huge network of smart and connected objects which can interact with other devices without our interposition. Radio frequency identification (RFID) is a great technology and an interesting candidate to provide communications for IoT networks, but numerous security and privacy issues need to be considered. In this paper, we analyze the security and ...

Bacterial translation initiation factor IF2 promotes ribosomal subunit association, recruitment, and binding of fMet-tRNA to the ribosomal P-site and initiation dipeptide formation. Here, we present the solution structures of GDP-bound and apo-IF2-G2 of Bacillus stearothermophilus and provide evidence that this isolated domain binds the 50 S ribosomal subunit and hydrolyzes GTP. Differences bet...

The EPCglobal Class-1 Generation-2 UHF tag standard is certain to become the de facto worldwide specification for inexpensive RFID tags. Because of its sharp focus on simple “license plate” tags, it supports only the most rudimentary of security and privacy features, and essentially none of the cryptographic techniques that underpin authentication and privacy-protection in higher-powered comput...

Polynomial Pythagorean hodograph (PH) curves form a remarkable subclass of polynomial parametric curves; they are distinguished by having a polynomial arc length function and rational offsets (parallel curves). Many related references can be found in the article by Farouki and Neff on C1 Hermite interpolation with PH quintics. We extend the C1 Hermite interpolation scheme by taking additional c...
