We propose a security architecture that provides two fundamental security services for VANETS: i) non-repudiation and ii) privacy enhancement. Due to a new PKI concept, referred to as PKI+, users are autonomous in deriving public keys, certificates and pseudonyms which minimizes the communication to the certificate authority. Security techniques are(More)
—Universal approximation is the basis of theoretical research and practical applications of fuzzy systems. Studies on the universal approximation capability of fuzzy systems have achieved great progress in recent years. In this paper, linear Takagi–Sugeno (T–S) fuzzy systems that use linear functions of input variables as rule consequent and their special(More)

Abstract—Analysis of neural data with multiple modes and high density has recently become a trend with the advances in neuroscience research and practices. There exists a pressing need for an(More)
• We designed an approach to measure the synchronization strength of non-stationary nonlinear data against phase differences. • We demonstrated that the synchronization analysis was an effective indicator of an epileptic focus location. • We developed a parallelized approach with general-purpose computing on the graphics processing unit (GPGPU), and it(More)
BACKGROUND Oleic acid (OA) stimulates vascular smooth muscle cell (VSMC) proliferation and migration. The precise mechanism is still unclear. We sought to investigate the effects of peroxisome proliferator-activated receptor gamma (PPARgamma) coactivator-1 alpha (PGC-1alpha) on OA-induced VSMC proliferation and migration. PRINCIPAL FINDINGS Oleate and(More)
