Let D be a digraph, V (D) and A(D) will denote the sets of vertices and arcs of D, respectively. A (k, l)-kernel N of D is a k-independent set of vertices (if u, v ∈ N then d(u, v), d(v, u) ≥ k) and l-absorbent (if u ∈ V (D) \N then exists v ∈ N such that d(u, v) ≤ l). A k-kernel is a (k, k − 1)-kernel. We propose an extension of the definition of (k, l)-kernel to (arc-)weighted digraphs, verif...

We present new cryptographic protocols for multi-authority secret ballot elections that guarantee privacy, robustness, and universal verifiability. Application of some novel techniques, in particular the construction of witness hiding/indistinguishable protocols from Cramer, Damg̊ard and Schoenmakers, and the verifiable secret sharing scheme of Pedersen, reduce the work required by the voter or ...

The essential oil from flowering aerial parts of Nepeta macrosiphon Boiss. growing wild in Kermanshah Province, Iran, was analyzed by GC/MS. This essential oil was prepared by a modified Likens-Nickerson’s simultaneous distillation-extraction (SDE) method. Forty-five compounds consisting 95.1% of the total components were identified from the oil obtained with a yield of 0.1%w/w. Among them, spa...

This paper presents an asymptotical analysis of the MUSIC and Pencil-MUSIC methods for estimating 2-D angles and polarizations using crossed dipoles. The explicit first order expressions for the variances of the MUSIC and Pencil-MUSIC estimates are derived. Both the theoretical and simulation results are used to analyze and compare the performances of the MUSIC and Pencil-MUSIC methods. A numbe...

In this paper we examine the notion of plaintext awareness as it applies to hybrid encryption schemes. We apply this theory to the Cramer-Shoup hybrid scheme acting on fixed length messages and deduce that the Cramer-Shoup scheme is plaintext-aware in the standard model. This answers a previously open conjecture of Bellare and Palacio on the existence of fully plaintext-aware encryption schemes.
