The aim of this review paper is to expose a new state of matter exhibited by strongly correlated Fermi systems represented by various heavy-fermion （HF） metals, two-dimensional liquids like 3He, compounds with quantum spin liquids, quasicrystals, and systems with one-dimensional quantum spin liquid. We name these various systems HF compounds, since they exhibit the behavior typical of HF metals. In HF compounds at zero temperature the unique phase transition, dubbed throughout as the fermion condensation quantum phase transition （FCQPT） can occur; this FCQPT creates flat bands which in turn lead to the specific state, known as the fermion condensate. Unlimited increase of the effective mass of quasiparticles signifies FCQPT; these quasiparticles determine the thermodynamic, transport and relaxation properties of HF compounds. Our discussion of numerous salient experimen- tal data within the framework of FCQPT resolves the mystery of the new state of matter. Thus, FCQPT and the fermion condensation can be considered as the universal reason for the non-Fermi liquid behavior observed in various HF compounds. We show analytically and using arguments based completely on the experimental grounds that these systems exhibit universal scaling behavior of their thermodynamic, transport and relaxation properties. Therefore, the quantum physics of different HF compounds is universal, and emerges regardless of the microscopic structure of the compounds. This uniform behavior allows us to view it as the main characteristic of a new state of matter exhibited by HF compounds.

俄罗斯是世界上唯一的一个横跨亚洲和欧洲两个大洲的国家,并且传承了苏联最多遗址的国家,并且,它也是世界上领土面积最大的国家同时还是联合国五个常任理事国之一,其国家有着丰富的自然资源并且具备人口稀少即地广人稀的显著特点。中国在改革开放以来的发展越来越受到全世界的关注和重视,原因之一是中国的发展速度不断加快和实力的不断提高;另外,当今世界,对于世界十大经济体并且也是常任理事国之一的中国来说,地域问题和政治问题在历史舞台上的作用显得尤为重要。,中国和俄罗斯作为发展中的两个大国就现有的环境而言具备很好的投资合作空间和条件以及具备非常可观的发展前景空间。中俄两国地域相邻,历史渊源颇深。俄罗斯盛产矿产、石油、天然气等资源能源,是世界公认的能源大国、科技大国、军事大国,科研实力雄厚,但在物流设施、金融等方面比较落后;而中国是全球最大的加工业基地,生产能力强,互联网金融与物流行业发展迅速,但资源能源匮乏,对矿产、天然气等能源的需求极大,可见,中俄两国的投资经济存在很强的互补性。所以,研究中国对俄直接投资和中俄经济的关系可以为中俄未来的投资与经贸合作的战略转型提供依据,以充分发挥两者的互补效应。分析中国直接投资对俄罗斯经济产生的影响的研究不多,从1992到2017年关于中国对俄罗斯直接投资的资料比较少,并且也没有深入分析中俄投资合作的投资规模、投资地区分布、投资行业以及投资方式这方面的资料很重要,力求在理论上丰富中国直接投资对俄罗斯经济影响这一研究领域,将为中俄投资合作提供理论支持。目前双方的投资结构和投资规模对拉动双边经贸关系的战略升级所起的作用十分有限。为此,从俄罗斯人的角度来看直接投资问题的具有现实意义。本篇论文从投资规模、投资地区分布情况、投资行业以及投资方式四个方面全面分析中国对俄罗斯直接投资存在的问题。论文对中国对俄罗斯直接投资的过去、现在延续状况,对其特点、发展变化做出判断,然后从理论上探寻中国对俄罗斯直接投资怎么影响俄罗斯经济,为实证分析做铺垫。统计数据计算分析对象,建立数学模型,实证分析怎么中国投资影响俄罗斯经济。本文选取相应的指标作为解释变量,具体选取的指标有:国内投资率、劳动力投入、人力资源、政府总体消费支出占GDP的百分比、中国对俄罗斯直接投资流入量、中国的外商直接投资与国内投资之间的交互作用、人力资本和中国外商直接投资的交互项、俄罗斯经济政策和外国直接投资的交互作用。结果表明,劳动力投入、人力资本改善、国内投资增加、中国的外商直接投资流入增加均对俄罗斯的经济发展起到正向的促进作用,政府消费支出对经济增长起到负向的影响,但这种影响并不大,这可能是由于俄罗斯的经济财政政策还不太完善,政府消费支出没能正向的对经济发展起到作用。三个交互影响的变量中,中国外商直接投资与政府消费支出对经济发展起到正向的影响,而与预测不一致的是中国外商直接投资与国内投资的交互项和中国外商直接投资与人力资本的交互项,对经济发展的影响是负的。在宏观层面上,中国直接投资对俄罗斯的经济增长产生了积极作用,以及外国直接投资对其他经济增长贡献因素产生了溢出效应,可以预测在改善俄罗斯的腐败、贸易便利化不足等各种不良影响因素的情况下,其积极作用将更为明显。因此,本文提出一些可以为俄中投资与经济关系的发展提供新动力的政策建议。

本研究属于语言学研究范围,主要目的是研究使用机器翻译系统翻译俄文科技文本时遇到的问题。机器翻译系统中的文本翻译问题在不同国家都受到关注,以往有不少学者对不同语言间的机器翻译进行研究,并且已经针对某些语言组(如英汉、英法、日汉等)开发出自动分析文本可译性的系统。但是,在俄汉翻译方面,目前的研究数量还非常有限,现有的研究也不够详尽和深入。俄罗斯与中国的关系向来紧密,相互之间的政治、经济、文化交流一直非常频繁,俄语与汉语直接的翻译问题非常值得关注,在人机交互日益深入的今天,详细研究俄汉机器翻译问题十分必要。本研究以科技文献为主要研究对象,以三种最常用的在线机器翻译系统Google Translate,Yandex Translate,Baidu Translate为主要翻译工具,对大量文本进行详细考察,分析不同语言句子中可译性标记,研究整理了影响翻译结果的俄语语言特征,并根据这些语言特征来判断俄语文本可译性标记。该研究的实践部分包括三个阶段:首先,收集相应的翻译结果,根据已确定的可译性标记判断翻译效果;然后,对文本进行前后期编辑,以确定可改善翻译结果的可能性;最后,通过比较分析翻译结果,确定每个在线机器翻译系统句子翻译的正确率。通过这一研究,我们明确了俄语中对机器翻译影响最大的一些语言特征,并确定了辅助机器翻译的前后期编辑所需的步骤。最后,我们列出各种使句子翻译变得复杂的因素,形成文本可译性数据,以供翻译实践及研究者参考。本研究表明,目前的在线翻译系统总体来说能够提供相当令人满意的翻译结果,但是,句子中一些特定的可译性标记可能会影响文本的翻译输出,需要通过前后期编辑来辅助翻译,改善结果。这些在线翻译系统不断得到改进和发展,表明它们在科技文本翻译实践方面很有发展前景。

Holonic Architecture of the Smart Grid

Smart Grid and Renewable Energy 2013年第2期4卷 202-212页

作者： Ebisa Negeri Nico Baken Marjan popov Electrical Sustainable Energy Delft University of Technology Delft The Netherlands Network Architectures and Services Delft University of Technology Delft The Netherlands

With the growing concerns about sustainable energy, energy efficiency and energy security, the electrical power system is undergoing major changes. Distributed energy sources are becoming widely available at the lower parts of the grid. As a result, more and more end consumers are transforming from passive consumers to active “prosumers” that can autonomously generate, store, import and/or export power. As prosumers increasingly dominate the power system, the system demands capability that allows enormous number of stakeholders with heterogeneous types to exchange power on the grid. Unfortunately, the classical power system cannot efficiently handle this scenario since it was designed for centralized power distribution. Thus, restructuring the rather old power system is indispensable. In this paper, we apply the holonic approach to structure the smart grid as a system that is bottom-up organized from autonomous prosumers that are recursively clustered at various aggregation layers. Based on this, we present a control architecture of the smart grid using holonic concepts. Our control architecture is characterized by autonomy of the prosumers, distributed control, recursive self-similar control structures at different aggregation levels. Further, we present a service oriented architecture (SOA) framework that models the control functions that make up the holonic control architecture. Our proposed control architecture is tested using a simulation set-up.

Role of the receptor for advanced glycation end products in hepatic fibrosis

World Journal of Gastroenterology 2009年第46期15卷 5789-5798页

AIM： To study the role of advanced glycation end products （AGE） and their specific receptor （RAGE） in the pathogenesis of liver fibrogenesis. METHODS： In vitro RAGE expression and extracellular matrix-related gene expression in both rat and human hepatic stellate cells （HSC） were measured after stimulation with the two RAGE ligands, advanced glycation end product-bovine serum albumin （AGE- BSA） and N＇-（carboxymethyl） lysine （CML）-BSA, or with tumor necrosis factor-α （TNF-α）. In vivo RAGE expression was examined in models of hepatic fibrosis induced by bile duct ligation or thioacetamide. The effects of AGE-BSA and CML-BSA on HSC proliferation, signal transduction and profibrogenic gene expression were studied in vitro. RESULTS： In hepatic fibrosis, RAGE expression was enhanced in activated HSC, and also in endothelial cells, inflammatory cells and activated bile duct epithelia. HSC expressed RAGE which was upregulated after stimulation with AGE-BSA, CML-BSA, and TNF-α.RAGE stimulation with AGE-BSA and CML-BSA did not alter HSC proliferation, apoptosis, fibrogenic signal transduction and fibrosis- or fibrolysis-related gene expression, except for marginal upregulation of procollagen α1（ I ） mRNA by AGE-BSA. CONCLUSION： Despite upregulation of RAGE in activated HSC, RAGE stimulation by AGE does not alter their fibrogenic activation. Therefore, RAGE does not contribute directly to hepatic fibrogenesis.

The Phenomenological Approach in Teaching

The Phenomenological Approach in Teaching

引用

作者： Dmitriy popov Svetlana Kudryashova Vladimir Sokol Yaroslavl State University

Being one of the leading philosophical directions, phenomenology offers an approach for various scientific scopes to benefit from. Among these scopes, education and teaching constitute the most important ones. The phenomenological approach in teaching is widely applied in different educational spheres and in different countries. An analysis of this approach reveals a variety of contributing phenomenological schools. The paper also emphasizes the relevance and potential attainability of a unified basis for this approach.

Using ***'s Approach to Actualize ***'s Ideas

引用

作者： Dmitry popov Anton Skutin Vladimir Sokol Yaroslavl State University Ural Federal University Tyumen State University

In the course of research concerning the phenomenology approach, the authors have found out that many of E. Husserl's ideas lost their significance even in the phenomenology framework due to the transition to postphenomenology. When previously it happened to the ideas of I. Kant, H. Cohen managed to update them for the contemporary philosophy and influence the development of modern philosophy. Based on the H. Cohen's approach, the authors attempted to actualize E. Husserl's ideas and achieved approbated results applying phenomenology to the philosophy of consciousness, education, ethics and linguistic philosophy.

利用直流磁分离及脉冲阴极双激发源等离子弧薄膜沉积装置制备了含Ti底层和无Ti底层的类金刚石碳薄膜(DLC);采用纳米硬度计、原子力显微镜和X射线光电子能谱仪分析了薄膜的力学性能和结构;采用УСК-1型球-盘滑动摩擦磨损试验机考察了薄膜的摩擦性能.结果表明,同无Ti底层的DLC薄膜相比,含Ti底层的DLC薄膜的硬度和弹性模量较低;含Ti底层的DLC薄膜经真空400℃退火后表面层中存在TiO2,内部存在TiC;而无Ti底层的DLC薄膜经真空500℃退火处理后硬度、弹性模量和表面形貌几乎保持不变;无Ti底层的DLC薄膜经空气中500℃退火后摩擦系数明显降低,这是由于DLC薄膜在空气中热处理时更易发生石墨化所致.
