Can “Zombie Enterprises” Find Self-Help Road through Technological Innovation?  [PDF]
Jingru Liang
Chinese Studies (ChnStd) , 2017, DOI: 10.4236/chnstd.2017.63017
Abstract: “Cutting overcapacity” is the primary task of supply-side structural reform in China, which focuses on “disposing and eliminating zombie enterprises firmly”. “Zombie enterprises” usually refer to those who fall into a financial crisis but rely on the support of the government or the bank to survive. At present, the research of “zombie enterprise” by scholars at home and abroad is mainly concentrated in the macro level. But this paper argues that the enterprise is a specific market player, therefore, if you want to crack the “zombie enterprise” problem fundamentally, you should ultimately start from the enterprise, promoting the efficient use of resources through technological innovation, which helps enterprises to establish core competitiveness and drives the sustainable development of enterprises.

American Journal of Industrial and Business Management (AJIBM) , 2018, DOI: 10.4236/ajibm.2018.85088
Abstract: Using the patent applications data of listed firms in China from 2005 to 2014, this paper examines how the pay gap in the top management team influences enterprise innovation. The result shows that the number of patent applications especially the number of patents for invention increases significantly when the pay gap enlarges. It means the enlargement of the pay gap in the top management team could incent executives to make innovation decisions, to promote outputs of high-quality patents for invention. Finally the quality of enterprise innovation has been improved. Especially, the incentive effect of the pay gap in the top management team is more significant in private enterprises and enterprises with strong financing constraints. Therefore, enterprises in these two groups have better innovation behaviors.
Methodology of life cycle impact assessment for Chinese products

Yang Jianxin,WANG Rusong,Liu Jingru,

环境科学学报 , 2001,
Abstract: The methodological basis and procedures for determination of Chinese normalisation references and weighting factors in life cycle impact assessment for Chinese products is described. The normalisation reference is determined by the per capita environmental impact potential for the area in question in 1990 (EP(j)90). The weighting factor is determined as the normalisation reference (ER(j)90) divided by society's target contribution in the year 2000 based on Chinese reduction plans, ER(j)T2000. Two simple indicators, environmental impact load(EIL) and resource depletion index(RDI) are recommended.

International Journal of Molecular Sciences , 2013, DOI: 10.3390/ijms14023556
Abstract: Basic fibroblast growth factor (FGF-2) is an important member of the FGF gene family. It is widely used in clinical applications for scald and wound healing in order to stimulate cell proliferation. Further it is applied for inhibiting stem cell differentiation in cultures. Due to a shortage of plasma and low expression levels of recombinant rbFGF in conventional gene expression systems, we explored the production of recombinant rbFGF in rice grains ( Oryza sativa bFGF, OsrbFGF). An expression level of up to 185.66 mg/kg in brown rice was obtained. A simple purification protocol was established with final recovery of 4.49% and resulting in a yield of OsrbFGF reaching up to 8.33 mg/kg OsrbFGF. The functional assay of OsrbFGF indicated that the stimulating cell proliferation activity on NIH/3T3 was the same as with commercialized rbFGF. Wound healing in vivo of OsrbFGF is equivalent to commercialized rbFGF. Our results indicate that rice endosperm is capable of expressing small molecular mass proteins, such as bFGF. This again demonstrates that rice endosperm is a promising system to express various biopharmaceutical proteins.

People can obtain the different intension of service with different knowledge background and technique. In this paper, service is recognized in the views of 12 levels. Through the description and analysis of these 12 levels, the method for existing services is summarized. Thereby the important impact on service science is elaborated in the modern economy.
Metabolism and driving forces analysis of Chinese urban households

LIU Jingru,WANG Rusong,WANG Zhen,YANG Jianxin,

生态学报 , 2003,
Abstract: The household sector is the key field of sustainable consumption research. To analyze the ecological impacts of household consumption, HOMES project introduced the concepts of Household Metabolism. In ecological science, metabolism refers to the material cycles and energy flow that determine the viability and continuation of organism-environment interaction. On household level, the concept of household metabolism is a metaphor to study the integral pattern of natural resource flows into and out of households.First, we introduced the concept model of household metabolism, which includes three key factors and three kinds of main flows. The key factors are direction, quantity and velocity of flow. The three kinds of flows are water, energy and material. Then using this model we analyzed the change of household metabolism of Chinese urban household during the last twenty years. Rather than taking into account all the natural resources of household consumption, we just focused on water and energy flow. The increasing trends of urban household metabolism are very clear in China. Natural, economic and social factors are the main driving forces behind these trends. According to the experiences of developed counties, we concluded that the increasing trends will keep on in a short-middle period.
Computing the Rectilinear Center of Uncertain Points in the Plane
Haitao Wang,Jingru Zhang
Computer Science , 2015,
Abstract: In this paper, we consider the rectilinear one-center problem on uncertain points in the plane. In this problem, we are given a set $P$ of $n$ (weighted) uncertain points in the plane and each uncertain point has $m$ possible locations each associated with a probability for the point appearing at that location. The goal is to find a point $q^*$ in the plane which minimizes the maximum expected rectilinear distance from $q^*$ to all uncertain points of $P$, and $q^*$ is called a rectilinear center. We present an algorithm that solves the problem in $O(mn)$ time. Since the input size of the problem is $\Theta(mn)$, our algorithm is optimal.

The distribution and morphology alterations of microfilaments and microtubules in the mesophyll cells and root-tip cells of wheat seedlings, which had been radiated by enhanced ultraviolet-B (10.08 KJ·m-2·d-1), were examined through the confocal laser scanning microscope (Model FV1000, Olympus, Japan). Microtubule was labeled with an indirect immunofluorescence staining method, and microfilament was labeled with fluorescein isothiocyanate-phalloidin (FITC-Ph) as probes. The results indicated that microtubules in mesophyll cells, compared with the controls, would be depolymerized significantly, and dispersed randomly showing some spots or short rods in the cytoplasm, under the enhanced UV-B radiation condition. The microtubule bundles tended to be diffused, and the fluorescence intensity of that significantly decreased. The distribution pattern of microfilaments, which usually arranged parallelly in control cells, was broken up by enhanced UV-B radiation. We further investigated the distribution and morphology of microtubules in root-tip cells during every stage of cell division, and found that these aberrant phenomena of microtubules were often associated with abnormal cell division. Our findings suggested that the distribution, morphology and structure of cytoskeleton in mesophyll cells and root-tip cells of wheat seedlings would be affected by enhanced UV-B radiation, which might be related to abnormal cell division caused by enhanced UV-B radiation as an extracellular signal.

Abstract: Overexpression of manganese superoxide dismutase (MnSOD) can sensitize a variety of cancer cell lines to many anticancer drugs. Recent work has shown that cancer cells can be sensitized to cell killing by raising peroxide levels through increased manganese superoxide dismutase (MnSOD) when combined with inhibition of peroxide removal. Here we utilize the mechanistic property of one such anticancer drug, BCNU, which inhibits glutathione reductase (GR), compromising the glutathione peroxidase system thereby inhibiting peroxide removal. The purpose of this study was to determine if anticancer modalities known to produce superoxide radicals can increase the antitumor effect of MnSOD overexpression when combined with BCNU. To enhance MnSOD, an adenoviral construct containing the cDNA for MnSOD (AdMnSOD) was introduced into human breast cancer cell line, ZR-75-1. AdMnSOD infection alone did not alter cell killing, however when GR was inhibited with either BCNU or siRNA, cytotoxicity increased. Futhermore, when the AdMnSOD + BCNU treatment was combined with agents that enhance steady-state levels of superoxide (TNF-α, antimycin, adriamycin, photosensitizers, and ionizing radiation), both cell cytotoxicity and intracellular peroxide levels increased. These results suggest that the anticancer effect of AdMnSOD combined with BCNU can be enhanced by agents that increase generation of superoxide.

Abstract: Short-cut nitrification and denitrification was started up and maintained in a lab-scale A2/O process treating low C/N ratio domestic wastewater by controlling DO concentration in low level and decreasing the aerobic actual hydraulic retention time (AHRT).The average nitrite accumulation rate reached about 90% and above 95% of ammonia nitrogen (NH4+-N) could be removed.The genome DNA of the enriched ammonia oxidizing bacteria (AOB) culture was extracted and amplified,and then electrophoresed on agarose gel twice.The DNA fragments in reamplified agarose gel bands were recovered and purified,and then used as standard molecule.A standard curve of real-time fluorescent PCR was set up for AOB quantification.The numbers of the AOB in sludge samples under different operational conditions and nitrite accumulation rates were monitored and compared by using real-time quantitative PCR.The results showed that the numbers of AOB significantly increased with increasing of nitrite accumulation rates.The numbers of AOB in the complete nitrification activated sludge and short-cut nitrification activated sludge were 5.28×109 cells/g MLVSS and 3.95×1010 cells/g MLVSS,respectively.Moreover,the decrease of the nitrite accumulation rates lagged behind the decline of AOB numbers.
