Novel disjoint path selection scheme based on link availability in ASON

The Journal of China Universities of Posts and Telecommunications 2007年第3期14卷 70-73页

Risk-disjoint routing is an efficient way to improve network survivability. In this article, a partial risk-disjoint routing algorithm based on link availability （PRDRA-LA） is proposed based on the complete risk-disjoint routing algorithm （CRDRA）. While calculating the protection path with PRDRA-LA, the links that share risks with the links in the working path are filtered by link availability. In addition, the risk disjoint degree between the protection path and the working path can be adjusted freely. Simulation results showed that when compared with CRDRA, routing connections with PRDRA-LA can achieve improved survivability while the number of connections that can be successfully routed over the current network is kept from serious decline.

Objective: To evaluate the effectiveness and safety of Chinese medicine(CM) for Idiopathic pulmonary fibrosis(IPF) patients. Methods: To screened relevant articles, Pub Med, Cochrane Library, Excerpta Medica Datase(EMBASE), China National Knowledge Infrastructure(CNKI), Chinese VIP Information(VIP), Wanfang Database and Chinese Biomedical Database(CBM) were searched in English or Chinese until December 2015 for randomized controlled trials, which compared CM treatment(CM group) with Western medicine or placebo(control group) on IPF. The outcome measures included acute exacerbation, pulmonary function, the St George’s respiratory questionnaire(SGRQ) scores, 6-minute walk test(6 MWT) distance, adverse events and mortality. Results: This meta-analysis included 25 randomized controlled trials involving 1,471 patients. Compared with the control group, CM group was superiori in reducing the risk of exacerbation [relative risk(RR)=0.40, 95% CI 0.22 to 0.72, P0.05). This meta-analysis also revealed that CM therapy significantly decreased the SGRQ score(SMD=–0.60, 95% CI –1.14 to –0.05, P0.05) between CM and control groups. Conclusions: The pooled outcomes suggest that CM treatment appears benefit in reducing the risk of exacerbation, improving lung function and decreasing the incidence of adverse effects and enhancing the quality of life. However, the outc

Chinese Science Bulletin 2002年第6期47卷 470-475页

作者： Xiaofeng Zhang Yan gu Zhimin feng Liqin Ban Meifu feng National Laboratory of Biomembrane and Membrane Biotechnology Institute of Zoology Chinese Academy of Sciences Beijing China

Cellular immune response is a major barrier to xenotransplantation. Human tumor necrosis factor-α (hTNF-α) possesses cross-species activity and directly amplifies the immune rejection via the upregulation of adhesion molecules on porcine endothelium. We investigated the role of protein tyrosine phosphorylation in the induction of expression of E-selectin and vascular cell adhesion molecule-1 (VCAM-1), and the augmentation of adhesion of human peripheral blood monocytes (PBMo) and natural killer cells (PBNK), after rhTNF-α-stimulation of porcine aortic endo-thelial cells (PAEC) in vitro. rhTNF-α-increased adhesiveness of PAEC for both PBMo and PBNK was dose-dependently reduced by pretreatment of PAEC with the selective protein tyrosine kinase (PTK) inhibitor genistein. The inhibitory effect occurred at the early time of PAEC activation triggered by rhTNF-α, and was completely reversible. PTK activity assay indicated that genistein also suppressed rhTNF-α stimulated activation of protein tyrosine

A novel and facile method of introducing 4-hydroxyl group into the aromatic ring of azabenzanthrone compounds was carried out by reacting azabenzanthrone compounds with hydrazine hydrate or hydroxylamine hydrochloride and sodium hydroxide in diethylene glycol （DEG） solvent. The mechanism of reaction may involve an amino intermediate and follow a hydroxyl substitution process.

Genetic algorithm for autonomic joint radio resource management in end-to-end reconfigurable systems

引用

The Journal of China Universities of Posts and Telecommunications 2008年第1期15卷 11-17页

作者： ZENG xian MA Tao LIN Yue-wei feng Zhi-yong Key Laboratory of Universal Wireless Communications Beijing University of Posts and Telecommunications Ministry of Education Beijing 100876 China

This article presents the genetic algorithm （GA） as an autonomic approach for the joint radio resource management （JRRM） amongst heterogeneous radio access technologies （RATs） in the end-to-end reconfigurable systems. The joint session admission control （JOSAC） and the bandwidth allocation are combined as a specific decision made by the operations of the genetic algorithm with certain advisable modifications. The proposed algorithm is triggered on the following two conditions When a session is initiated, it is triggered for the session to camp on the most appropriate RAT and select the most suitable bandwidth for the desired service. When a session terminates, it is also used to adjust the distribution of the ongoing sessions through the handovers. This will increase the adjustment frequency of the JRRM controller for the best system performance. Simulation results indicate that the proposed autonomic JRRM scheme not only effectively reduces the handover times, but also achieves well trade-off between the spectrum utility and the blocking probability.

Effect of rotational excitation on stereodynamics for the N(2D)+H_(2)(v =0,j =0 - 5)→NH(v',j')+H collision reactions is investigated by employing the quasiclassical trajectory *** on an accurate 12 A″ potential energy surface,three angular distributions P(θr),P((φ)r),P(θr,(φ)r),and polarized-dependent differential cross section 2π/σ dσ00/dwt are calculated at a collision energy of 5.1 kcal/*** is found that the P(θr) distribution has a distinct peak at about θr =90°.The P((φ)r) distribution has a small peak at about (φ)r =270° and no peak at about (φ)r =90°.This implies that the product angular momentum j' is not only aligned perpendicular to k,but also orientated to the negative direction of the y *** product rotational alignment and orientation become increasingly weaker with an increase of the rotational quantum number j of H_(2).Analysis of trajectory propagation demonstrates that the title collision reaction has a dominant indirect insertion mechanism and a minor direct H-abstraction mechanism.

Phase Transition and Oxygen Ion Diffusion in （La1-xLnx）2Mo2O9 （Ln=Nd, Gd, x=0.05-0.25） Using Dielectric Relaxation Method

引用

Chinese Journal of Chemical Physics 2008年第3期21卷 270-274页

作者： Qian-feng Fang Zhong Zhuang xian-ping Wang Dan Li Jian-xin Wang Ningbo Institute of Material Technology and Engineering Chinese Academy of Sciences Ningbo315040 China Key Laboratory of Materials Physics Institute of Solid State Physics Chinese Academy of SciencesHefei 230031 China

Dielectric relaxation method was employed to study the properties of oxygen ion diffusion and phase transition in the oxide-ion conductors （Lal-xLnx）2Mo209 （Ln=Nd, Gd, x=0.05-0.25）. Two dielectric loss peaks were observed： peak Pd at about 600 K and peak P5 around 720 K. Peak Pd is a relaxational peak and associated with the short-range diffusion of oxygen ions, while peak P5 hardly changes its position and dramatically decreases in height with increasing frequency, exhibiting non-relaxational nature. With increasing Ln^3＋ concentration, the heights of peak Ph and Pd increase at first and then decrease after passing a maximum at 15% doping. It is suggested that peak P5 is related to the phase transition of a static disordered state to a dynamic disordered state in oxygen ions/vacancies distribution. It is found that the 15%Gd or 15%Nd doped La2Mo209 samples exhibit the highest conductivity in accordance with the highest height of peak Pd at this doping content.
