The major immunoregulatory effects of vasoactive intestinal peptide (VIP) are mediated by structurally distinct types I (VIPR1) and II (VIPR2) G protein-associated receptors on some T cells, B cells, and macrophages. Identification of the separate immunologic activities of each type of VIPR has been complicated by the usual expression of only VIPR2 or of(More)
A great many algorithms of video encryption have been proposed nowadays with the necessity of data rights management, especially the selective video encryption algorithms, which ensure the security of the information and meanwhile reduce the data to encrypt. The residue data, intra-prediction modes, inter-prediction modes and motion vectors are key elements(More)

In this paper, we propose a novel in-situ pair-wise key establishment scheme based on master key updating and knowledge of post deployment for large-scale distributed wireless sensor networks. Our scheme aims at achieving a satisfying key sharing probability among sensors with low memory overhead. Our scheme employs location information of post deployment(More)

A number of self-healing group key distribution schemes have been proposed recently, however, though practicality analysis and simulation of the commonly used self-healing group key distribution schemes, we show that almost none of the existing schemes are suitable for large-scale and resource-constricted wireless sensor networks in real-world applications,(More)
Hexakis(m-phenylene ethynylene) macrocycles 1 bearing multiple hydrogen-bonding side chains and containing inner cavities modified with different functional groups are synthesized based on Pd-catalyzed (Sonogashira) coupling of monomeric building blocks to trimeric precursors that are recombined and coupled to give macrocycles with different substitution(More)
Water biostability is of particular concern to water supply as a major limiting factor for heterotrophic bacterial growth in water distribution systems. This study focused on bacterial growth dynamics in the series dilution of water samples with TOC (total organic carbon) values determined beforehand. The results showed that the specific growth rate of(More)
Physical-layer authentication can address physical layer vulnerabilities and security threats in wireless sensor networks, and has been considered as an effective complementary enhancement to existing upper-layer authentication mechanisms. In this paper, to advance the existing research and improve the authentication performance, we propose a novel physical(More)
This article mainly introduced one kind of key assignment scheme based on traditional symmetrical cryptogram system. It divides keys in system from lowers to high into three ranks - primary key, secondary key and the host master key. The primary keys cannot appear in the plaintext form, but are transmitted and preserved in the form of encryption. The(More)
