Optimization of the Hydrological Model Using Multi-objective Particle Swarm Optimization Algorithm

An application of multi-objective particle swarm optimization （MOPSO） algorithm for optimization of the hydrological model （HYMOD） is presented in this paper. MOPSO algorithm is used to find non-dominated solutions with two objectives： high flow Nash-Sutcliffe efficiency and low flow Nash- Sutcliffe efficiency. The two sets＇ coverage rate and Pareto front spacing metric are two criterions to analyze the performance of the algorithms. MOPSO algorithm surpasses multi-objective shuffled complex evolution metcopolis （MOSCEM_UA） algorithr~, in terms of the two sets＇ coverage rate. But when we come to Pareto front spacing rate, the non-dominated solutions of MOSCEM_ UA algorithm are better-distributed than that of MOPSO algorithm when the iteration is set to 40 000. In addition, there are obvious conflicts between the two objectives. But a compromise solution can be acquired by adopting the MOPSO algorithm.

Tracing Changes in the Microbial Community of a Hydrocarbon-Polluted Soil by Culture-Dependent Proteomics

Hydrocarbon contamination may affect the soil microbial community, in terms of both diversity and function. A laboratory experiment was set-up, with a semi-arid control soil and the same soil but artificially contaminated with diesel oil, to follow changes in the dominant species of the microbial community in the hydrocarbon-polluted soil via proteomics. Analysis of the proteins extracted from enriched cultures growing in Luria-Bertani （LB） media showed a change in the microbial community. The majority of the proteins were related to gIycolysis pathways, structural or protein synthesis. The results showed a relative increase in the complexity of the soil microbial community with hydrocarbon contamination, especially after 15 days of incubation. Species such as Ralstonia solanacearum, Synechococcus elongatus and different Clostridium sp. were adapted to contamination, not appearing in the control soil, although Bacillus sp. dominated the growing in LB in any of the treatments. We conclude that the identification of microbial species in soil extracts by culture-dependent proteomics is able to partially explain the changes in the diversity of the soil microbial community in hydrocarbon polluted semi-arid soils, but this information is much more limited than that provided by molecular methods.

Community Structure and Seasonal Variation of Soil Arthropods in the Forest-Steppe Ecotone of the Mountainous Region in Northern Hebei,China

Soil fauna have been receiving more and more attention because they play an important role in nutrient cycling.However,there is a lack of information on soil arthropods in the forest-steppe ecotone in the mountainous region of northern Hebei,which makes it difficult to meet the need of protecting biodiversity in this area.Soil arthropod communities were investigated in the forest-steppe ecotone in northern Hebei province to provide basic information on changes in mountain soil fertility,which could promote the development of soil arthropod communities in mountain ecotones.From the preliminary identification,a total of 7994 individual soil arthropods were collected,which belonged to 25 groups,6 classes and 24 orders.Acarina,Hymenoptera and Collembola were the dominant groups in the ecotone.The number of Acarina was higher than Collembola,and this phenomenon was obviously different from other areas in the same climate zone.The increased abundance of rare groups in the Forest zone with the richer vegetation,higher arthropod abundance and more substantial litter depth,could be interpreted as a reaction to the suitable soil environment and food supply.And these rare groups were sensitive to environmental changes,which could be regarded as biotic indicators for evaluating soil quality.The analysis of community diversity showed that the abundance index (d),the Shannon-Wiener index (H'),the evenness index (J) and the density-group index (DG) were significantly higher in the forest zone,lower in the forest-steppe zone,and lowest in the meadow-steppe zone.Seasonal variations in community composition correlated with changes in average air temperature and precipitation in this ecotone.Groups and individuals of soil arthropod communities in the three zones were present in greater numbers in the middle of the rainy season than in the early or late periods of the rainy season as a whole.At the same time,seasonal changes in soil arthropod communities from different plots were also influenced by habitat condition.

Total Occlusion of Anterior Descending Artery （AD） without ST-Segment Elevation： DE Winter Pattern

The recognition of the presence of ST-segment elevation in the context of ACS （acute coronary syndrome） is fundamental for the good outcome of the case. However, some electrocardiographic patterns have been highlighted by the fact that there is no elevation, but they represent a severity similar to ACS with ST elevation. Hence, it is necessary that doctors who do the first service recognize these standards promptly.The electrocardiographic pattern of association between the ST-segment depression and the hyperacute T waves representing myocardial infarction in the anterior wall, localizing more specifically in the anterior descending artery, now known as the De Winter pattern, was first described by Dressler, and then described by Winter six years later. Winter observed that, out of a series of 1,452 cases, 2% of patients with anterior wall infarction had the pattern of ST-segment depression, positive and symmetrical T waves, and occasionally mild ST-segment elevation at AVR derivation. Those patients are admitted to the emergency room with a typical chest pain. However, because the electrocardiographic findings of this syndrome are not known to many health professionals, in many cases the patients do not receive adequate care and have fatal outcome, since mortality is relevant in these cases. Thus, the rapid recognition of this pattern is extremely necessary for the correct and effective intervention.

The Power of Money in FS. Fitzgerald＇s The Great Gatsby

The topic of this paper is the pursuit of cultural studies focusing on cultural hegemony, introduces the notion of the dominant groups＇ power to control society. It will also raise the issue of how hegemonic classes live in 1920s. The objective is to analyze, using cultural studies, Antonio Gramsci＇s Hegemony, Scott Fitzgerald＇s The Great Gatsby in order to come to some conclusions about depictions of aristocratic classes and powers in order to dominate powerless groups. Specifically, the research focuses on Jay Gatsby＇s struggles to face the hegemony of aristocratic groups, whose affluent supremacy. In the story, the new moneyed group, represented by Jay Gatsby, lives in West Egg while the aristocratic group, represented by Tom Buchanan, lives in East Egg. Tom is always the winner because he comes from the aristocratic groups, whose prestigious family. Therefore, Gatsby always loses compete against Tom no matter how hard Gatsby tries. By learning Gatsby＇s struggle in this novel, we gain a better understanding of how other powerless groups, not only in American society, but also other society in the world, who also struggle to compete with the aristocratic groups.

Cultural Binary Particle Swarm Optimization Algorithm and Its Application in Fault Diagnosis

Binary particle swarm optimization algorithm(BPSOA) has the excellent characters such as easy to implement and few set parameters.But it is tendentious to stick in the local optimal solutions and has slow convergence rate when the problem is complex.Cultural algorithm(CA) can exploit knowledge extracted during the search to improve the performance of an evolutionary algorithm and show higher intelligence in treating complicated problems.So it is proposed that integrating binary particle swarm algorithm into cultural algorithm frame to develop a more efficient cultural binary particle swarm algorithm (CBPSOA) for fault feature selection.In CBPSOA,BPSOA is used as the population space of CA;the evolution of belief space adopts crossover,mutation and selection operations;the designs of acceptance function and influence function are improved according to the evolution character of BPSOA.The tests of optimizing functions show the proposed algorithm is valid and effective.Finally,CBPSOA is applied for fault feature selection.The simulations on Tennessee Eastman process (TEP) show the CBPSOA can perform better and more quickly converge than initial BPSOA.And with fault feature selection,more satisfied performance of fault diagnosis is obtained.

Fault diagnosis for on-board equipment of train control system based on CNN and PSO-SVM hybrid model

Rapid and precise location of the faults of on-board equipment of train control system is a significant factor to ensure reliable train operation.Text data of the fault tracking table of on-board equipment are taken as samples,and an on-board equipment fault diagnosis model is designed based on the combination of convolutional neural network(CNN)and particle swarm optimization-support vector machines(PSO-SVM).Due to the characteristics of high dimensionality and sparseness of fault text data,CNN is used to achieve feature extraction.In order to decrease the influence of the imbalance of the fault sample data category on the classification accuracy,the PSO-SVM algorithm is introduced.The fully connected classification part of CNN is replaced by PSO-SVM,the extracted features are classified precisely,and the intelligent diagnosis of on-board equipment fault is implemented.According to the test analysis of the fault text data of on-board equipment recorded by a railway bureau and comparison with other models,the experimental results indicate that this model can obviously upgrade the evaluation indexes and can be used as an effective model for fault diagnosis for on-board equipment.

Rhizomic Identity, Performative Identity, In-Becoming Identity of the Characters in Maryse Cond6＇s Narratives

In Western culture, the symbol of the tree which divides into branches and has a foliage of the same lineage as its roots is the best symbol for describing identity and also for describing the Cartesian reasoning which proceeds by eliminating misconceptions and following thesingle true idea. In the West Indies culture, it is the rhizome that is the best symbol to describe the identity of these peoples. The rhizome as explained by Deleuze and Gattari in their Introduction Rhizome of the book .4 thousand plateaus, is a tuber that makes roots after being cut off from its original plant. In this respect, it is most appropriate to describe the people of the Caribbean who have been cut off from their African roots by slavery but who have thrived on the island, re-establishing links with the different peoples who came to work there. The rhizome is similar to the mangrove that protects the island from marine erosion, it intertwines with other plants so that it is impossible to distinguish the source plant. In this respect, it is the best symbol to describe the creole identity and the refusal of the West Indians to return to a racial and social system that promulgated the white race as superior to the black race during colonialism. The structure of the books of Maryse Cond6 is itself rhizomatic since it does not present the theme of its stories through the view point of an omnipotent author but through the view points of all the characters of the novel who by their discussions letthe reader discover their terrible history of slavery, and transform himinto a new man who would seek diversity.

The Role of Memory and Tradition in the Construction of Identity in the Nineteenth-Century Bahamas

Tradition has been defined as practices brought forward from the past into the present. In the context of enslavement and the cultural dislocation that accompanied it, memory became critical in the recreation of tradition. Individual memory contributed to the practices that created new traditions to be carried forward by subsequent generations. Archaeological evidence from Clifton Plantation, Bahamas, illustrates how memory and tradition shaped the identities of both enslaver and enslaved, and influenced the construction of an African Bahamian identity in the early nineteenth-century. In their consumer selections, the enslaved people of Clifton were constructing artifact assemblages that reflected their memories of their traditional cultural background. In the process they were creating an Afro-Bahamian aesthetic that would become a tradition for future generations of Bahamians. While the goods were not of their own manufacture, the choices were theirs from the selection available to them. At the same time, those of British heritage were signaling their British identity through their consumer choices. However, Clifton was unusual in being owned by a reformer who sought to ameliorate the conditions of slavery. The paper also briefly discusses whether these concepts are useful in understanding the material culture of enslaved Africans at other sites.

Personal Adaptation and Spiritual Potential in Childhood Today in the Lithuania

The Lithuania 2011 Childhood is not just a product of human development but also a product of society＇s educational and spiritual culture development. This paper aims to disclose how nowadays the family helps the child to develop adaptation instruments which would help to adapt to the society in a micromacro environment, to show what helps the child to become a member of a social group, of the society, what adaptation problems arise during the childhood. Problems of school adaptation of the first-formers have not been properly assessed and analysed so far, though they foresee the future. No proper attention has been paid to the development of the harmonious personality during the pre-school period and to the correction of their adaptation during the firstschool year. The paper deals with the child＇s experiences of the pre-school period as the factor influencing school adaptation in the first form. Variety and quality of children＇s experiences are directly related and most of all depend on the family of the spiritual institution, so its impact is the strongest in terms of the development of the child＇s personality. The goal is to disclose the importance of selfdevelopment in childhood, which determines future success. The object is selfdevelopment during childhood today in the Lithuania. Methods of investigation are： the analysis of pedagogical, psychological, philosophical literature; the analysis of empiri.cal researches and statistic data; and the method of observation. The hypothesis is： The cause of the firstformers＇ school adaptation difficulties incompletely realised adaptation potential during the preschool period.

山东沂水刘家店子春秋墓铜器三题

1977年冬、1978年2月,山东省沂水县刘家店子村发现和发掘了两座春秋中期的墓葬和一座车马坑,出土了包括青铜器在内的大批文物。其中,两件青铜鼎和两件青铜罍的形制、装饰纹饰具有早期青铜器特点,当为"古式"青铜器。车马坑内出土的部分青铜容器,可能与铭文中习见的"旅器"有关,表明这些祭器并非用于宗庙祭祀,而是"外用"之器。墓葬出土的青铜缶及青铜甗形盉为典型的"群舒"风格器物;此外,鲁东南地区出土的双耳兽首鼎形匜、青铜鼎耳装饰"点线纹"的作风也可能与"群舒"文化因素相关。

A physics-based hydro-geomorphologic simulation utilizing cluster parallel computing

To conduct a large-scale hydrologic-response and landform evolution simulation at high resolution,a complex physics-based numerical model,the Integrated Hydrology Model(InHM),was revised utilizing cluster parallel computing.The parallelized InHM(ParInHM) divides the simulated area into multiple catchments based on geomorphologic features,and generates boundary-value problems for each catchment to construct simulation tasks,which are then dispatched to different computers to start the simulation.Landform evolution is considered during simulating and implemention in one framework.The dynamical Longest-Processing-Time(LPT) first scheduling algorithm is applied to job management.In addition,a pause-integratedivide-resume routine method is used to ensure the hydrologic validity during the simulation period.The routine repeats until the entire simulation period is finished.ParInHM has been tested in a computer cluster that uses 16 processors for the calculation,to simulate 100 years' hydrologic-response and soil erosion for the 117-km2 Kaho'olawe Island in the Hawaiian Islands under two different mesh resolutions.The efficiency of ParInHM was evaluated by comparing the performance of the cluster system utilizing different numbers of processors,as well as the performance of non-parallelized system without domain decomposition.The results of this study show that it is feasible to conduct a regional-scale hydrologic-response and sediment transport simulation at high resolution without demanding significant computing resources.

Scale dependence in the phylogenetic relatedness of alien and native taxa

Aims Darwin’s naturalization hypothesis proposes that successfully established alien species are less closely related to native species due to differences in their ecological niches.Studies have provided support both for and against this hypothesis.One reason for this is the tendency for phylogenetic clustering between aliens and natives at broad spatial scales with overdispersion at fine scales.However,little is known about how the phylogenetic relatedness of alien species alters the phylogenetic structure of the communities they invade,and at which spatial scales effects may manifest.Here,we examine if invaded understorey plant communities,i.e.containing both native and alien taxa,are phylogenetically clustered or overdispersed,how relatedness changes with spatial scale and how aliens affect phylogenetic patterns in understorey communities.Methods Field surveys were conducted in dry forest understorey communities in south-east Australia at five spatial scales(1,20,500,1500 and 4500 m2).Standardized effect sizes of two metrics were used to quantify phylogenetic relatedness between communities and their alien and native subcommunities,and to examine how phylogenetic patterns change with spatial scale:(i)mean pairwise distance and(ii)mean nearest taxon distance(MNTD).Important Findings Aliens were closely related to each other,and this relatedness tended to increase with scale.Native species and the full community exhibited either no clear pattern of relatedness with increasing spatial scale or were no different from random.At intermediate spatial scales(20-500 m2),the whole community tended towards random whereas the natives were strongly overdispersed and the alien subcommunity strongly clustered.This suggests that invasion by closely related aliens shifts community phylogenetic structure from overdispersed towards random.Aliens and natives were distantly related across spatial scales,supporting Darwin’s naturalization hypothesis,but only when phylogenetic distance was quantified as MNTD.Phylogenetic dissimilarity between aliens and natives increased with spatial scale,counter to expected patterns.Our findings suggest that the strong phylogenetic clustering of aliens is driven by human-mediated introductions involving closely related taxa that can establish and spread successfully.Unexpected scale-dependent patterns of phylogenetic relatedness may result from stochastic processes such as fire and dispersal events and suggest that competition and habitat filtering do not exclusively dominate phylogenetic relationships at fine and coarse spatial scales,respectively.Distinguishing between metrics that focus on different evolutionary depths is important,as different metrics can exhibit different scale-dependent patterns.

The Production of Alternative Media in China's Mainland： A Case Study of the Journal Friend Exchange

Through an ethnographic study of the journal Friend Exchange that is part of the Health Prevention Project for Homosexuals in China's Mainland, this article explores the following two issues ： （ 1 ） Friend Exchange is used as an example for studying the dynamic operation of alternative media by analysing its production and circulation with a vision of multiculturalist equality, （ 2 ） Friend Exchange is a media representation of the gay community, which can reflect the construction of the public sphere for the underprivileged in China. The examination of these two issues will help us critically review contemporary communication studies.

Hitchhiker＇s guide to genetic diversity in socially structured populations

When selection increases the frequency of a beneficial gene substitution it can also increase the frequencies of linked neutral alleles through a process called genetic hitchhiking. A model built to investigate reduced genetic diversity in Pleistocene hominins shows that genetic hitchhiking can have a strong effect on neutral diversity in the presence of culturally mediated mi- gration. Under conditions in which genetic and cultural variants are transmitted symmetrically, neutral genes may also hitchhike to higher frequencies on the coattails of adaptive cultural traits through a process called cultural hitchhiking. Cultural hitchhiking has been proposed to explain why some species of matrilineal whales display relatively low levels of mitochondrial DNA diver- sity, and it may be applicable to humans as well. This paper provides a critical review of recent models of both types of hitch- hiking in socially structured populations. The models＇ assumptions and predictions are compared and discussed in the hope that studies of reduced genetic diversity in humans might improve our understanding of reduced genetic diversity in other species, and vice versa
