Entanglement has been recognized as being crucial when implementing various quantum information ***, quantifying entanglement for an unknown quantum state requires nonphysical operations or post-processing measurement data. For example, evaluation methods via quantum state tomography require vast amounts of measurement data and likely estimation.

Journal of Thermal Science 2012年第4期21卷 302-310页

Unsteady behaviors as well as unsteady cascade flow fields of a single-stage axial flow compressor were experi- mentally investigated by detail measurements of unsteady performance characteristics and casing wall pressure and internal flow velocity fluctuations. The main feature of the test compressor is a capacity tank connected di- rectly to the compressor outlet in series through slits and a concentric duplex pipe, and also jet nozzles in order to inject compressed air toward the rotor tip region. Research attention is focused on the post-stall characteristics of surge and rotating stall which occur simultaneously. When the compressor was connected to the capacity tank, surge was generated with rotating stall in accordance with the capacitance increment of whole compressor system The surge behavior changed irregularly with throttling valve installed behind the compressor, and several types of surge cycles were observed. In addition, the surge cycle changed by jet injection to the rotor tip region. The re- suits suggested that the blockages of the cascade flow which were generated by a stall cell play an important role in deciding the surge behaviors.

目前,日本民俗学的艺术研究基本处于停滞状态。然而,日本民俗类艺术研究的这种停滞状态仅为现状。在20世纪10至30年代,包括山本鼎的“农民美术运动”、柳宗悦的“民艺运动”、柳田国男与竹内胜太郎等人的“民俗艺术论”、今和次郎的“考现学”、柳田国男的艺术论、鹤见俊辅的“限界艺术论”在内,民俗类艺术论以如今已难以想象的百花齐放之态得到了积极的讨论。这些艺术论本是各自独立诞生的,但在关注偏离中心的艺术即“vernacular艺术”这方面有着共通之处。因此,探讨在当下民俗学中不断开辟新局面的vernacular概念,从将其应用于艺术的vernacular艺术的视角出发回顾日本的民俗类艺术论,并探究新的民俗类艺术论是有必要的。vernacular艺术这一视角,对于深入探讨游离于官方、正式、正统抑或主流、高蹈的,带有权威性和中心性的艺术之外的、属于普通人的艺术有着重要意义。同时,这一视角不仅关注传统,还将生活在“此刻·此处”的普通人不受“传统”桎梏的创作活动纳入研究视野,也为拓展当代民俗学和艺术人类学的研究领域和研究对象做出了重要贡献。

We study an M/PH/1 queue with phase type working vacation and vacation interruption where the vacation time follows a phase type distribution. The server serves the customers at a lower rate in a vacation period. The server comes back to the regular busy period at a service completion without completing the vacation. Such policy is called vacation interruption. In terms of quasi birth and death process and matrix-geometric solution method, we obtain the stationary queue length distribution. Moreover we obtain the conditional stochastic decomposition structures of queue length and waiting time when the service time distribution in the regular busy period is exponential.

本文论述了日本农村近代化过程中出现的vernacular式的所有权观念和资源利用方式。日本政治和经济的近代化始于19世纪中叶,政府积极引入了西方的法律、制度、技术及知识。然而,生活在农村地区的人们,一边自觉或不自觉地游离于西方逻辑之外,一边创造出与自身独立和自我生存相关的vernacular经济形式。既往的经济史和法律史研究侧重于正统历史,鲜有涉及vernacular经济问题,而本文则聚焦日本农村的vernacular经济现象,揭示出蕴含其中的“半”思想。

AIM: To observe the regional distributions and morphological features of nesfatin-1/nucleobindin-2 (NUCB2) immunoreactive (IR) cells in the rodent digestive system. METHODS: Paraffin-embedded sections of seven organs (pancreas, stomach, duodenum, esophagus, liver, small intestine and colon) dissected from sprague-dawley (SD) rats and institute of Cancer Research (ICR) mice were prepared. The regional distributions of nesfatin-1/NUCB2 IR cells were observed by immunohistochemical staining. The morphological features of the nesfatin-1/NUCB2 IR cells were evaluated by hematoxylin and eosin (HE) staining. Fresh tissues of the seven organs were prepared for Western blotting to analyze the relative protein levels of NUCB2 in each ***: Immunohistochemical staining showed that the nesfatin-1/NUCB2 IR cells were localized in the central part of the pancreatic islets, the lower third and middle portion of the gastric mucosal gland, and the submucous layer of the duodenum in SD rats and ICR mice. HE staining revealed that the morphological features of nesfatin-1/NUCB2 IR cells were mainly islet cells in the pancreas, endocrine cells in the stomach, and Brunner’s glands in the duodenum. Western blotting revealed that NUCB2 protein expression was higher in the pancreas, stomach and duodenum than in the esophagus, liver, small intestine and colon (P = 0.000). CONCLUSION: Nesfatin-1/NUCB2 IR cells are expressed in the pancreas, stomach and duodenum in rodents. These cells may play an important role in the physiological regulation of carbohydrate metabolism, gastrointestinal function and nutrient absorption.
