sufficient conditions are investigated for the global stability of the solu tions to models based on nonlinear impulsive differential equations with ＂supremum＂ and variable impulsive perturbations. the main tools are the Lyapunov functions and Razu mikhin technique. two illustrative examples are given to demonstrate the effectiveness of the obtained results.

the level of genetic variation among individuals may affect performance by reducing the ability of prey to detect and escape from predators if lack of genetic variation reduces flight ability directly or indirectly through reduced parasite resistance. We investigated vulnerability of common avian prey species to predation by the sparrowhawk Accipiter nisus and the goshawk A. gentilis in relation to an index of genetic similarity among adults of potential prey species. We estimated a prey vulnerability in- dex that reflects the abundance of prey relative to the expected abundance according to local population density, and related this index to band sharing coefficients based on analyses of minisatellites for adults in local breeding populations. the prey vulnera- bility index was positively correlated with the band sharing coefficient in both predators, even when controlling for potentially confounding variables. these findings indicate that prey species with high band sharing coefficients, and hence low levels of genetic variation, are more readily caught by avian predators. therefore, predation may constitute a major cost of low levels of genetic variation in extant populations of prey [Current Zoology 61（1）： 1-9, 2015].

In response to peripheral nerve injury, the inflammatory response is almost entirely comprised of infiltrating macrophages. Macrophages are a highly plastic, heterogenic immune cell, playing an indispensable role in peripheral nerve injury, clearing debris and regulating the microenvironment to allow for efficient regeneration. there are several cells within the microenvironment that likely interact with macrophages to support their function – most notably the schwann cell, the glial cell of the peripheral nervous system. schwann cells express several ligands that are known to interact with receptors expressed by macrophages, yet the effects of schwann cells in regulating macrophage phenotype remains largely unexplored. this review discusses macrophages in peripheral nerve injury and how schwann cells may regulate their behavior.

Graftech公司的Apollo电极系统在2008年年初应用于安赛乐米塔尔公司卢森堡迪弗丹格厂直流电弧炉上,目的是为了降低其石墨电极的总成本。在稳定的电炉操作条件下,2008年上半年电极单耗出现了显著和稳定的改善。这个积极效果来自于两方面:真正地消除了电极残头损失以及持续降低电极折断率。通过提供增值技术服务和支撑,Graftech公司也在减少电极折断和相关损失方面提供了帮助:首先,对废钢塌方和非导电的检测制度进行了微调,同时也对伺服器的信号低频过滤器进行了优化;其次,通过使用sMED(单分快速换模法)精益管理方法,电极操作的稳定性和效率也得到了改善;最后,Graftech公司对于破损的零碎电极提供再加工服务,然后成功投入二次使用,这种服务也减少了电极的实际统计消耗,使得电极统计消耗接近于净损耗。此外,电极消耗也得益于电炉操作条件的改进(废钢预热)带来的电能消耗降低,不过这个改进因素需单独考虑其影响。以上措施,在过去的两年里促进电极单耗和相关的碳排放减少了35%。本文主要目的是想通过阐述使用Apollo石墨电极系统的方法,如使用Apollo石墨电极系统消除电极残头、改进电极使用制度减少折断、应用电极sMED方法提高生产力以及优化电炉操作条件等,来帮助其他电炉钢厂降低石墨电极的总成本。

We address a framework for the analysis of extended fuzzy logic(FLe) and elaborate mainly the key characteris-tics of FLe by proving several qualification theorems and proposing a new mathematical tool named the A-granule. specifically, we reveal that within FLe a solution in the presence of incomplete information approaches the one gained by complete infor-mation. It is also proved that the answers and their validities have a structural isomorphism within the same context. this rela-tionship is then used to prove the representation theorem that addresses the rationality of FLe-based reasoning. As a conse-quence of the developed theoretical description of FLe, we assert that in order to solve a problem, having complete information is not a critical need; however, with more information, the answers achieved become more specific. Furthermore, reasoning based on FLe has the advantage of being computationally less expensive in the analysis of a given problem and is faster.

Plant cell walls contain elaborate polysaccharide networks and regulate plant growth, development, mechanics, cell-cell communication and adhesion, and defense. Despite conferring rigidity to support plant structures, the cell wall is a dynamic extracellular matrix that is modified, reorganized, and degraded to tightly control its properties during growth and development. Far from being a terminal carbon sink, many wall polymers can be degraded and recycled by plant cells, either via direct re-incorporation by trans- glycosylation or via internalization and metabolic salvage of wall-derived sugars to produce new precur- sors for wall synthesis. However, the physiological and metabolic contributions of wall recycling to plant growth and development are largely undefined. In this review, we discuss long-standing and recent evi- dence supporting the occurrence of cell-wall recycling in plants, make predictions regarding the develop- mental processes to which wall recycling might contribute, and identify outstanding questions and emerging experimental tools that might be used to address these questions and enhance our understanding of this poorly characterized aspect of wall dynamics and metabolism.

In recent years, experienced rapid economic the Pearl River Delta has growth which may create a substantial burden to its ecology. In this study, the wetlands of the Pearl River Delta are investigated. through the use of remote sensing methods, we analyze spatial and temporal variations of wetlands in this area over the past twenty years. the support vector machine （sVM） method is proven to be an effective approach for classifying the wetlands of the Pearl River Delta, and the total classifica- tion resolution reaches 94.94% with a Kappa coefficient exceeding 0.94, higher than other comparable analysis methods. Our results show that wetland areas were reduced by 36.9% during the past twenty years. the change detection analysis method shows that there was a 95.58% intertidal zone change to other land-use types, most of which （57.12%） was converted to construction land. In addition, farmland was reduced by 54.89% during the past twenty years, 47.19% of which was changed to construction land use. the inland water area increased 19.02%, but most of this growth （18.77%） was converted from the intertidal zone.

We argue that in Universes where future and past differ only by the entropy content a psychological arrow of time pointing in the direction of entropy increase can arise from natural selection in biological evolution. We show that this effect can be demonstrated in very simple toy computer simulations of evolution in an entropy increasing or decreasing environment.
