多芯光纤可大幅提高光纤的传输容量,但芯间串扰会导致网络资源分配面临更大挑战。文章分析了多芯光纤网络的路由、纤芯选择和频谱分配问题,建立了考虑纤芯间串扰的优化模型,以最小化网络最大占用频隙号为优化目标,首次设计了一种基于协同进化的优化算法,以解决路由、纤芯选择和频谱分配问题。根据最大请求优先排序策略将连接请求降序排列,利用整数编码分别为路由和纤芯选择设立不同种群,结合单点交叉与均匀变异,采用差异化的精英保留进化策略,以搜索路由、纤芯选择和频谱分配问题的全局最优解。完成所提算法在两种不同网络拓扑下的性能评估,实验结果表明,所提算法可实现网络频谱资源的高效利用,业务承载分布更均衡。

Osteoporosis is one of the most common and frequently-occurring diseases．The research of the pathogenesis and prevention of osteoporosis become more important．In recent years， studies have shown that decrease of bone mass often accompanied with the increase of adiposite tissue in the bone marrow．The occurrence of osteoporosis may be related to the proportion of adipogenesis and osteogenesis in the bone metabolism．Bone marrow adipose tissue plays an important supporting role in bone formation and hematopoiesis．It has the endocrine function of releasing a series of important secretory factors， such as leptin， adiponectin， chemerin， resistin， visfatin， etc．， in the regulation of adipocyte differentiation by bone marrow stormal cells （BMSCs）．Chemerin is a newly identified adipokine．It plays an important role in the immune respone， lipid metabolism， carbohydrate metabolism， inflammation， and other physiological and pathological processes．Chemerin as well as leptin and adiponectin are involved in the regulation of bone metabolism and in maintenance of the balance of bone metabolism．Activation of chemerin and its receptor CMKLR１ signal pathway may regulates the differentiation of BMSCs， stimulates the formation of osteoblasts， and further affects bone remodeling．The mechanism of the effect of chemerin ／CMKLR１ signal pathway on bone metabolism is not clear．In-depth study of the relation between chemerin of osteoporosis may further understand the pathogenesis of osteoporosis， and provide new ways for treatment and prevention of the disease． [ABSTRACT FROM AUTHOR]

Based on the research concept of catalytic depolymerization, using the Gary-King retort, the effect of catalyst and accessory ingredient in the catalytic depolymerization of Inner Mongolia lignite were investigated by adding catalyst with accessory ingredient, only adding catalyst and only adding accessory ingredient. The results showed that the addition of catalyst or accessory ingredient intervened the coal pyrolysis and products yield of gases or liquid phases. When only adding accessory ingredient, the fracture degree of the hydroxyl and fat side chains in the coal is deepened; when only adding catalyst, the fracture, dehydrogenation and aromatization of the bridge bond in coal are promoted; and when adding catalyst with the accessory ingredient, the superposition results of only adding catalyst and only adding accessory ingredient are reflected in all aspects, but the increase in tar yield reflects a certain degree of synergistic effect. Adding catalyst with the accessory ingredient is more beneficial for the formation of tar, which increased from 5. 84% of raw coal tar yield to 7. 28%. [ABSTRACT FROM AUTHOR]

Influenza virus is one of major threats to human health. To explore effective strategies for prevention a novel influenza pandemic, the effectiveness of the prevention interventions including border quarantine, case treatment, case isolation, social-antiviral prophylaxis, and vaccination for four different influenza were computed based on the constructed computational epidemic model of Beijing. The main results were as follows: border quarantine could only play very limited role in preventing an influenza pandemic; for novel influenza virus with transmissibility similar to A (HlNl)/2009 virus, only positive treatment of cases could effectively prevent pandemic in local; for novel influenza virus with transmissibility similar to A(H2N2)/1958 virus, high intensity treatment of cases plus isolation of these treated cases could effectively prevent pandemic; for novel influenza virus with transmissibility similar to A(HN1)/1918 virus, high intensity treatment of cases plus isolation of these treated cases and social-antiviral prophylaxis of treated cases could have a chance to prevent pandemic; for novel influenza virus with super transmissibility (Ro > 3.3), only broad-spectrum vaccine with certain effectiveness could prevent pandemic. These results had significant value for further developing emergency preparedness plans to response a novel influenza pandemic in huge cities of China. [ABSTRACT FROM AUTHOR]
