This paper presents a new nonparametric method to simulate probability density functions of some random variables raised in characterizing an anomaly based intrusion detection system (ABIDS). A group of kernel density estimators is constructed and the criterions for bandwidth selection are discussed. In addition, statistical parameters of these(More)
Diabetes exacerbates cardiovascular disease, at least in part through suppression of macrophage cholesterol efflux and levels of the cholesterol transporters ATP binding cassette transporter A1 (ABCA1) and ABCG1. The receptor for advanced glycation end products (RAGE) is highly expressed in human and murine diabetic atherosclerotic plaques, particularly in(More)
In the title complex, [Co(C2N3)2(C12H12N6)2] n the Co(II) atom lies on a centre of symmetry and displays a slightly distorted octa-hedral coordination geometry. The 1,2-bis-[(1,2,4-triazol-1-yl)meth-yl]benzene ligands link adjacent metal atoms into polymeric chains parallel to the c axis, forming centrosymmetric 26-membered metallamacrocycles. The(More)
Nearly monodispersed Ag3PO4 nanocrystals with size of 10 nm were prepared through a colloidal chemical route. It was proven that the synthesized Ag3PO4 nanoparticles have intrinsic peroxidase-like catalytic activity. They can quickly catalyze oxidation of the peroxidase substrate 3, 3, 5, 5-tetramethylbenzidine (TMB) in the presence of H2O2, producing a(More)
