Urban cultural space(UCS) has been of great social and economic value for sustainable development, and the existing researches about it mainly focus on some specific aspects, such as historical heritage or cultural service facility. However, UCS hasn't been quantitatively assessed as an independent system with clear definition and comprehensive classification. Thus, we present a quantitative analysis based on the statistic of UCS provision in different categories between 44 sub-districts in Xi'an and find its inequalities. Xi'an urban land use data and population data of sub-district level are introduced in the analysis process with GIS,SPSS and MATLAB. Our results indicate that inequalities of UCS in Xi'an are mainly reflected in three aspects, including categories, geospatial and population. Among the four categories of UCS, historical heritage and cultural park account for higher percentage, while cultural service facility and religious space are lower. The inequalities in geospatial could be estimated from two indicators. The first indicator named cultural space rate ranges from 0 to 66.88%, while the other named distance between residential and cultural space varies from 100.47 m to 2004.75 m. The inequalities in population could be assessed by cultural space per capita and Gini coefficient. The results indicate that per capita ranges from 0 m^2 to 214.79 m^2. The Gini coefficient of Xi'an is 0.86, which means that the UCS distribution in population is extremely inequitable. Our studies would further the research on UCS and provide constructive suggestions in urban planning and policy formulation to ensure adequate UCS provision and improve its distributional order in Xi'an.

In order to realize the fact that operational tasks can be decomposed flexibly with new tasks random adding, role-based approaches for operational tasks model and the flexibility decomposition are proposed. Firstly, aiming at the shortcomings of previous task decomposition methods, operational role concepts are introduced to design a computing framework of task flexibility decomposition. Within the framework, task structure matrixes are constructed for tasks decomposition with the mapping relations of information interaction and action process among tasks. On basis of this, via giving operational decomposition granularity, a flexibility approach of operational task decomposition is put forward with three parts about task decomposition granularity adjustment, tasks module partition with different operational role patterns and task decomposition scheme evaluation. Finally, as an application case shown, it is validated that the proposed approaches for tasks modeling and decomposition are available. By comparing with previous decomposition approaches, the proposed approach, within three types of operational roles, has strong environmental adaptability and scheme diversity, which can restrain calculation complexity increment for realizing task flexible decomposition effectively. © 2016 Beijing Institute of Aerospace Information.

Mathematical analysis of urban land use change in Xi'an city wall area by using parcel-level data

引用

Science China(Technological Sciences) 2019年第4期62卷 687-697页

作者： wang shusheng ZHAO Zi Liang XU YuQian LI XiaoLong State Key Laboratory of Green Building in Western China Xi'an University of Architecture and Technology College of Architecture Xi'an University of Architecture and Technology

Nowadays, more and more interdisciplinary approaches have been applied in urban planning, such as computer, mathematics and geography. However, the sophisticated mathematical methods such as transition matrix, joint-count, Bayes rules and Markov chain have not been deeply utilized in urban land use analysis. Furthermore, the newborn parcel-level urban land use data method has just been tested in a few cases and has not yet been adopted in ancient city area. Based on the above, this paper uses a series of mathematical methods and parcel-level urban land use data for quantification study in the Xi'an city wall area. Digitizing the maps compiled in 1935, 1963, 1995, 2007 and 2017 of the study area leads to the acquisition of the parcel-level urban land use data concerning the following four categories: Residential(R), Service(S), Culture(C) and Other(O). Then five parcel maps of different times will be built up. Through a series of mathematical analysis, the result shows that urban land use change in this area has three kinds of characteristics. For urban land use change speed, the period between 1995 and 2007 is the fastest while the period from 1963 to 1995 is the slowest. For the transition of urban land use, R and S are the main categories, and transition from R to S is the dominant change. Besides, dominated neighbors have positive effects on their transition. C is consistently increasing and has a clustering distribution. For the influence of other factors such as environment and policy, C is a special category that has the highest sensitivity to policies. The result clearly explains the data from the research into the evolution of urban land use in the study area work as a powerful support for land use planning and policy. The mathematical methods would provide a new perspective for the study in ancient Chinese cities.

Chinese Science Bulletin 2002年第20期47卷 1673-1679页

作者： Ml Zhiyong wang shusheng WU Naihu Institute of Developmental Biology Chinese Academy of SciencesBeijing 100080China Academy of Life Sciences Peking UniversityBeijing 100871China

Using an improved version of mRNA differential display technology, we have obtained a differentially displayed fragment RDP-8. Homologous comparison indicated that the fragment RDP-8 has high homology with the gene encoding maize small GTP-binding protein. By screening cDNA library of the rice Nongken 58N panicle using the newly obtained fragment RDP-8 as probe, we further found the full-length cDNA of osRACD gene that encodes a rice small GTP-binding protein. As compared with maize RACD gene, the osRACD of rice shows remarkable homology in both nucleotide sequence and amino acid sequence, 88% and 97% respectively. Evidence from RT-PCR study indicates that osRACD gene is related to photoperiod fertility conversion of photoperiod sensitive genie male sterility (PSGMS) rice.

Modern Significance of Chinese Urban Planning Traditions

引用

China City Planning Review 2020年第4期29卷 73-81页

作者： wang shusheng School of Architecture Xi'an University of Architecture and TechnologyXi'anP.R.China

China has an outstanding urban planning tradition, which lays down the historical foundation for a theoretical planning system with Chinese characteristics. Thus, revealing the significance of the Chinese urban planning tradition in a modern context becomes the key link. Based on the historical experience of Chinese urban planning, this paper attempts to reveal the significance of traditional Chinese urban planning in a modern context from four aspects: urban planning integrated with the natural landscape, urban humanistic and cultural space planning, urban heritage conservation and culture inheritance, and urban planning during an economically prosperous period. Traditional Chinese urban planning emphasizes the integration between city and natural landscape and is good at setting up a baseline of urban order based on the ingenuity of landscape. Moreover, Chinese urban planning focuses on the design of humanistic and cultural space structures as well as the role of urban planning in the cohesion of "the will of the people," inspiration of cultural pursuit, and historical spirit inheritance. Besides, Chinese planning tradition pays attention to the transformation of urban space through economic development and emphasizes the fundamental principle that new space should adhere to the original spatial order.

Upregulation of Spinal Voltage-Dependent Anion Channel 1 Contributes to Bone Cancer Pain Hypersensitivity in Rats

引用

Neuroscience Bulletin 2017年第6期33卷 711-721页

Voltage-dependent anion channel 1（VDAC1） is thought to contribute to the progression of tumor development. However, whether VDAC1 contributes to bone cancer pain remains unknown. In this study, we found that the expression of VDAC1 was upregulated in the L2–5 segments of the spinal dorsal horn at 2 and 3 weeks after injection of tumor cells into the tibial cavity. Intrathecal injection of a VDAC1 inhibitor significantly reversed the pain hypersensitivity and reduced the over-expression of Toll-like receptor 4（TLR4）. Intrathecal injection of minocycline, an inhibitor of microglia, also attenuated the pain hypersensitivity of rat models of bone cancer *** results suggest that VDAC1 plays a significant role in the development of complicated cancer pain, possibly by regulating the expression of TLR4.

Effect of Ultrasound-Assisted Extraction of Phenolic Compounds on the Characteristics of Walnut Shells

引用

Food and Nutrition Sciences 2018年第8期9卷 1034-1045页

Walnuts are one of nature’s more waste-heavy products. 67% of the nut is shell and husk, low value by-products that are rich in phenolic compounds. The phenolic compounds extracted from walnut shells are potentially good natural sources of antioxidants for the food and pharmaceutical industries. In this study, phenolic compounds were extracted using an ultrasonic bath, an ultrasonic probe and a standard shaking method. The extraction yield achieved with an ultrasonic probe was 51.2 mg GAE/g DW, two times higher than both the shaking method and the ultrasonic bath method which were 20.6 mg GAE/g DW and 25.8 mg GAE/g DW, respectively. Phenolic extraction was further improved by a size reduction of the walnut shells. The best extraction yield of 52.8 mg GAE/g DW was attained when the particle size was between 45 - 100 mesh. The ultrasonic probe treatment is the best method for extraction of phenolic compounds from walnut shells. Scanning electron microscopy (SEM) imaging indicated that the ultrasonic probe treatment could better rupture the hard structure of the cells, increasing the penetration of solvents and thus the extraction yield.
