噛 This paper presents a parallel framework of grid-based numerical algorithms where data dependencies between grid zones can be modeled by a directed acyclic graph (DAG). It consists of three parts on how to partition, order and calculate the vertices of digraph. Numerical results using hundreds of processors on two parallel machines show the efficiencies(More)
Xeroderma pigmentosum group A (XPA) participates in modulating recognition of DNA damage during the DNA nucleotide excision repair process. The XPA A23G polymorphism has been investigated in case–control studies to evaluate the cancer risk attributed to the variant, but the results were conflicting. To clarify the effect of XPA A23G polymorphism in cancer(More)
Received (received date) Revised (revised date) Accepted (accepted date) We review the security requirements for a vehicle communication network. We also provide a critical assessment of the security communication architectures and perform an analysis of the keys to design an efficient and secure vehicular network. We propose a novel unconditionally secure(More)
A fully homomorphic encryption (FHE) scheme is envisioned as being a key cryptographic tool in building a secure and reliable cloud computing environment, as it allows arbitrarily evaluation of a ciphertext without revealing the plaintext. However, existing FHE implementations remain impractical due to their very high time and resource costs. Of the(More)
A fully homomorphic encryption (FHE) scheme is envisioned as a key cryptographic tool in building a secure and reliable cloud computing environment, as it allows arbitrary evaluation of a ciphertext without revealing the plaintext. However, existing FHE implementations remain impractical due to very high time and resource costs. To the authors' knowledge,(More)
Fast multipole method (FMM) may reduce the complexity of N-body problems from O(N 2) to O(N log N) or O(N). It was applied in problems ranging from electromagnetic scattering to dislocation dynamics. FMM can be divided into two parts: commonness and individuality. A parallel solver of FMM commonly used in various applications has been designed and(More)
Received (received date) Revised (revised date) Accepted (accepted date) In a former paper [Fluct. Noise Lett., 13 (2014) 1450020] we introduced a vehicular communication system with unconditionally secure key exchange based on the Kirch-hoff-Law-Johnson-Noise (KLJN) key distribution scheme. In this paper, we address the secure KLJN key donation to(More)
