The role of the histamine H3 receptor (H3R) in cerebral ischaemia/reperfusion (I/R) injury remains unknown. Here we show that H3R expression is upregulated after I/R in two mouse models. H3R antagonists and H3R knockout attenuate I/R injury, which is reversed by an H3R-selective agonist. Interestingly, H1R and H2R antagonists, a histidine decarboxylase(More)
Hydrogen sulfide (H2S) used to be known as a toxic gas. However, in the last two decades, accumulating evidence has revealed its role as a bioactive molecule in the biological systems. H2S has relatively high expression in the brain, exerting multiple functions in both health and diseases. It modulates neurotransmission by influencing behaviors of NMDA(More)
In this paper we show that the problem of minimizing a nonlinear objective function subject to a system of fuzzy relational equations with max-min composition can be reduced to a 0-1 mixed integer programming problem. The reduction method can be extended to the case of fuzzy relational equations with max-T composition as well as those with more general(More)
First, the paper shows a novel sorting method based on delaminating coupling and support vector clustering (SVC). Secondly, it presents a notion of type-entropy. And recognition technology of type-entropy is introduced into signal sorting system so that a novel radar sequence signal sorting system is to be presented. The experiment result shows that the(More)
The conventional superimposed pilot applied in OFDM system has drawback of low accuracy. An iterative channel estimation algorithm based on superimposed pilot is proposed for the combination of orthogonal frequency division multiplexing (OFDM) and bit-interleaved coded modulation (BICM) system. This algorithm makes full use of the information provided by(More)
As radar signal environments become denser and radar signals become more complex, the task of an ESM operator becomes more difficult. This paper presented a de-interleaving/recognition system of radar pulses based on the combination of SVC and K-means clustering. Compared the conventional de-interleaving system, it can produce more complex and compact(More)
The developments in e-commerce and logistics technologies have motivated manufacturers to establish a new channel for retailing directly. We consider the setting that a manufacturer operates an online store in addition to the existing retail channel. There are two segments of customers, the lower-end customers need only physical products and visit(More)
Modern electronic warfare faces complex and dense pulses environments, which brings a severe challenge to radar signal sorting. A novel sorting method is presented based on delaminating coupling and support vector clustering (SVC) in this paper. The 3-dimension feature information is composed of direction of arrival, radio frequency and pulse width in this(More)
