Does the Method of Amalgamation Affect Cost Inefficiency of the New Municipalities?

Municipal amalgamation has been done in many countries in recent years as the result of a push to enlarge the size and coverage of local government units, which in turn is driven mainly by the prospect of economies of scale. However, while municipality amalgamation or boundary reform raises population size, it introduces organizational changes in the local government that might increase administrative inefficiency. The choice for the method of integration of administrative functions before amalgamation might affect to public expenditure after amalgamation. This study uses Japanese municipal-level data and argues for a relation between the choice for the method of integration of administrative functions and cost inefficiency after amalgamation. The results show that the fully distributed facility method is more likely to be adopted in a larger administrative jurisdiction and in one with large differences in finances or political structures between amalgamated sub-regions. Moreover, the results of stochastic frontier regression show that new municipality adopting fully distributed facility method can possibly increase inefficiency by expanding organizational slack because the new administration system will be insufficient integration of administrative functions.

Federated selective aggregation for on-device knowledge amalgamation

In the current work,we explored a new knowledge amalgama-tion problem,termed Federated Selective Aggregation for on-device knowledge amalgamation(FedSA).FedSA aims to train an on-device student model for a new task with the help of several decentralized teachers whose pre-training tasks and data are different and agnos-tic.The motivation to investigate such a problem setup stems from a recent dilemma of model sharing.Due to privacy,security or in-tellectual property issues,the pre-trained models are,however,not able to be shared,and the resources of devices are usually limited.The proposed FedSA offers a solution to this dilemma and makes it one step further,again,the method can be employed on low-power and resource-limited devices.To this end,a dedicated strategy was proposed to handle the knowledge amalgamation.Specifically,the student-training process in the current work was driven by a novel saliency-based approach which adaptively selects teachers as the par-ticipants and integrated their representative capabilities into the stu-dent.To evaluate the effectiveness of FedSA,experiments on both single-task and multi-task settings were conducted.The experimental results demonstrate that FedSA could effectively amalgamate knowl-edge from decentralized models and achieve competitive performance to centralized baselines.

Natural Silicate as a Solid Support for the Calix[4]Thiophosphorus Derivative for Removal Mercury (II), as Picrate from Water

Currently a technique widely used for gold extraction is mercury by amalgamation technique, the tailing produced pollutes water of all kinds, so it is necessary to develop a form of selective mitigation, for which it is necessary to use complexing agents based on calixarene functionalized with mercury sequestering agents. These are immobilized by adding supports based on natural silica to form polymers and make them insoluble in all types of solvents, so that they can be used as an extractor and at the same time regenerate to their original properties for continuous reuse.

The Causes and Consequences of China's Municipal Amalgamations:Evidence from Population Redistribution

Along with China's urbanization,the spatial redistribution of the country's population has led to difficulties for local governance,especially in areas experiencing population outflows.Municipal amalgamation is an ffctive response.This study uses administrative system code data that are accurate at the community and village level to verify the causal relationship between migration and village or community municipal amalgamation.It shows that migration has been an important reason for municipal amalgamation.Counties with greater population outflow have experienced more frequent amalgamation,manifesting a decrease in the numbers of villages and communities.This study,also examined the consequences of this amalgamation,finding that it can significantly alleviate local governments'fiscal pressures and promote public services in the long term.It is of great importance for improving the grassroots governance of population outflow areas during rapid urbanization in China.

The Dual of the Two-Variable Exponent Amalgam Spaces (Lq(),lp())(Ω)

Wiener amalgam spaces are a class of function spaces where the function’s local and global behavior can be easily distinguished. These spaces are ex-tensively used in Harmonic analysis that originated in the work of Wiener. In this paper: we first introduce a two-variable exponent amalgam space (Lq(),lp())(Ω). Secondly, we investigate some basic properties of these spaces, and finally, we study their dual.

3D modeling of deepwater turbidite lobes:a review of the research status and progress

Deepwater turbidite lobe reservoirs have massive hydrocarbon potential and represent one of the most promising exploration targets for hydrocarbon industry.Key elements of turbidite lobes internal heterogeneity include the architectural hierarchy and complex amalgamations at each hierarchical level leading to the complex distribution of shale drapes.Due to limitation of data,to build models realistically honoring the reservoir architecture provides an effective way to reduce risk and improve hydrocarbon recovery.A variety of modeling techniques on turbidite lobes exist and can be broadly grouped into pixel-based,process-based,process-oriented,surface-based,object-based and a hybrid approach of two or more of these methods.The rationale and working process of methods is reviewed,along with their pros and cons.In terms of geological realism,object-based models can capture the most realistic architectures,including the multiple hierarchy and the amalgamations at different hierarchical levels.In terms of data conditioning,pixel-based and multiple-point statistics methods could honor the input data to the best degree.In practical,dif?ferent methods should be adopted depending on the goal of the project.Such a review could improve the understanding of existing modeling methods on turbidite lobes and could benefit the hydrocarbon exploration activities of such reservoirs in offshore China.

Building,Amalgam和关联几何(II)——Building和关联几何

这里将要介绍的Building和关联几何的主要思想和不少理论都是由Tits提出和创立的.Tits最初提出Building这个几何结构是为了对例外复李群的存在加以几何解释.1955年Chevalley发表了李型群的开创性文章[9].文章中给出了一个一般性方法,使得对每一个复的单李代数和任何一个域,都构造出一个相应的李型群.这样一来,任意域上的例外李型群都获得了一个几何解释.但是,Tits所提出的Building这个几何结构对于研究相应群的各种性质仍然具有基本的意义,从而在有限李型单群的结构理论和表示论。

Gold mining has an impact on the contamination not only in industrial but in residential territories too. The mutual Russian Chinese investigation on mercury contamination of the Amur (Heilongjiang) River was proposed. The program of solving of the problems of mercury contamination in Russian gold mining areas is discussed.

Mercury-Free Gold Extraction Using Borax for Small-Scale Gold Miners

Small-scale gold mining is the largest anthropogenic contributor of mercury pollution on planet Earth. The miners grind gold ore together with mercury in order to recover the fine gold grains. The gold amalgam is burned whereby the mercury evaporates and gold is left behind. This processing extracts only a fraction of the gold in the ore and the released mercury causes serious global health and environmental problems. However, a mercury-free method described below has proved to extract up to twice as much gold without need of investment in new processing equipment and without longer processing time. The method has successfully been tested in the Philippines, Indonesia, Tanzania, Bolivia and Zimbabwe.

PA-DDS算法在HBV模型参数优化中的应用

影响水文模型预报精度的因素有很多,其中模型参数的优化对模拟结果起到至关重要的作用,目前用于参数优化的方法包括单目标优化和多目标优化两种。随着参数率定方法研究的深入,多目标分析问题越来越受到关注。Pareto存档动态维度搜索(Pareto-Archived Dynamically Dimensioned Search,PA-DDS)作为多目标优化算法,通过在求解过程中动态存储Pareto前沿以防止最优解的丢失,在寻优速度以及解的稳定性方面比较有优势。精英非支配排序遗传算法(NSGA-Ⅱ)具有寻优速度快、解集收敛性能好等优点,已经成为检验其他多目标优化算法性能的标准;AMALGAM算法通过对四种相关算法分配权重从而实现信息交换同时寻优,解的收敛性能较好。因此本文将PA-DDS算法与AMALGAM算法和精英非支配排序遗传算法(NSGA-Ⅱ)在收敛性能方面进行了对比,并将非劣解分布的均匀性及解的相似性方面与AMALGAM进行比较,利用尼泊尔巴格玛蒂河流域2005-2011年期间实测洪水日径流过程资料作为HBV模型参数率定系列,运用PA-DDS算法对模型参数进行优化,得出Pareto最优解,并利用2013年5场洪水日径流过程进行模型检验。结果表明:PA-DDS算法比AMALGAM算法能够更快地得到Pareto最优解且解的质量较好,拟合历史洪水平均确定性系数达到0.86,模型预报精度高,表明PA-DDS优化算法在解决多参数多目标优化问题中具有优势。

Electromagnetic Waves Collected by a Dental Amalgam Filling Induced Balance Dysregulation and Dizziness over a Period Exceeding 10 Years

This case report describes a woman aged approximately 50 years who has suffered from balance dysregulation and dizziness for more than 10 years. Although the subject underwent several examinations to confirm the etiology of her symptoms, the root cause remained unknown. The symptoms were thought to be caused by electromagnetic wave hypersensitivity because the subject experienced uneasiness and dizziness when a cell phone was held close to her body. A cell phone was used to diagnose the collection of harmful electromagnetic waves, and an amalgam filling was determined to be the cause. The amalgam filling was removed under strict protection, and the subject’s symptoms completely disappeared soon after the filling was removed.

寒区岩屑堆中汞化合物行为研究(英文)

At gold mining in the 19th～20th centuries on technogenous deposits of cryolitozone, considerable amounts of mercury-containing elements (amalgams) have been accumulated. Urgency of their utilization is caused by necessity of providing safe vital activity. It can be achieved when elaborating up-to-date technologies providing self-support of utilization as a consequence of extracting precious metals. Difficulty of this problem realization is caused by the absence of theoretical and applied elaborations of making the appropriate works in cryolitozone. The main trends of the problem solving on the grounds of creating scientific method foundations for investigating the cryolitozone amalgams transformation have been considered in the paper. Dynamics has been shown and the revealed regularities of their transformation, testifying of the occurrence of hydrometallurgic processes in cryolitozone massifs in situ, resulted in the decline of gold reserves at decreasing dispersity and increasing hallmarking, have been analyzed.

Near-Dead Cells to Special Tetraploidy to First Cells to Cancer Diagnostic Morphology: Unlikely Therapy-Gain from For-Profit Industrial Goliath

The objective in this experimental article is to gain evidential proof of near-dead cells, (sick-cells in relapse tumor) responding with recovery growth from special 4n, multi-chromatid chromosomes. Note, near-dead normal human cells with such converted chromosome structure gave rise to proliferative, fitness-gained, diploid first cells, which further gave rise to three different cell shape changed, recovery growth patterns. Previously, two cell shape changes had been recovered from same type normal human cells, transiently exposed to amino acid glutamine deficient growth medium with recovery growths also associated with presence of the special 4n cells. The 4n cell-division had been concluded to be a meiotic-like two-step division system to the fitness-gained diploid cells in numerous experiments. The main characteristics of this division system, was firstly whole genomes without polar oriented bent centromeres moving apart followed by much rarer simple fission division to two or three diploid cells, selectable for first cell proliferation. In general these 4n cells showed metaphase type rosette figures moving apart not in the normal spindle associated mitotic shape with centromeres polar-pointing with sloping arms. This sequence of events induced by glutamine-deficiency, was earlier shown to cause DNA breakage in metabolic studies however, the near-death condition was only assumed from normal fibro-blastic cell-sheet shrinkage. This was rectified by an RNA virus (Coxakie-B3), which virology known is a highly cell killing virus (4+ CPE on their scale). This virus replicates only in replicating cells, which led to recovery growths with progressive phenotypic cell-shape changes (spindle, polygonal and roundness cells), each intervened by “total” cell destruction. These three different growth patterns had morphologies, indistinguishably from today’s cancer diagnostic morphologies. “Mitotic” analyses of beginning growths for the three phenotypes revealed the special rosette figure separations from special 4n and higher ploidy level cells, and also total absence of spindle type mitoses. Tumorigenesis-relevant was centromere-puffing with premature chromatid separation, and chromatin compaction, a mechanism, that was suggested to protect the genome from damage (text). We suggest that the multi-chromatid polyploid cells with their genome reductive division system, can be a tractable in vitro model system for therapy information, when repeated from a cell-killing agent, producing virus-free recovery growths. Will it be enacted upon? Not likely with profit-greedy industrial Goliath in the helm of cancer research. But, a not for profit cancer organization, could change this appalling situation.
