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.
Does the Pay Gap in the Top Management Team Incent Enterprise Innovation?—Based on Property Rights and Financing Constraints  [PDF]

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.
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.

PLOS ONE , 2014, DOI: 10.1371/journal.pone.0102969
Abstract: Background Sex plays an important role in the clinical expression and prognosis of various cardiovascular diseases. This study was designed to observe the effects of sex on hypertrophic cardiomyopathy (HCM). Methods and Results A total of 621 unrelated patients with HCM without heart failure (460 males) were enrolled from 1999 to 2011. Compared to male patients, at baseline female patients were older at diagnosis (49.6±17.2 years vs. 46.7±14.4 years, P = 0.033), and had greater frequency of left ventricular outflow tract obstruction (72/161, 44.7% vs. 149/460, 32.4%, P = 0.005). During the average four year follow-up period (range 2–7 years), survival analysis showed that the incidences of mortality from all causes, cardiovascular death and progression to chronic heart failure were greater in women than in men (P = 0.031, 0.040 and 0.012, respectively). After adjustment for multiple factors that may confound survival and cardiac function, female sex remained an independent risk factor for all-cause mortality, cardiovascular death, and chronic heart failure [hazard ratio (HR) 2.19, 95% confidence interval (CI) 1.21–3.95, P = 0.010; HR 2.19, 95% CI 1.17–4.09, P = 0.014; HR 1.73, 95% CI 1.12–2.69, P = 0.014, respectively] in HCM patients. Subgroup analysis revealed that female sex as a risk factor was identified only in patients younger than 50 years old (P = 0.011, 0.011 and 0.009, respectively), but not for those 50 years or older. Conclusion Our results suggest that female sex is associated with worse survival and heart failure in HCM patients. Further studies are required to determine whether female hormones modify the clinical expression and prognosis of HCM.

American Journal of Plant Sciences (AJPS) , 2014, DOI: 10.4236/ajps.2014.522358
Abstract:
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.

The veterinary education is subjected to a new requirement due to the performance of the national standard veterinarian qualification examination. In the current review, the overview of veterinary education in Heilongjiang Bayi Agricultural University (HBAU) was described, and some positive suggestions were provided about the veterinary clinical diagnostics course, which is an important compulsory course undertaken by undergraduate, based on the national standard veterinarian qualification examination in China.
CL and FTIR analysis on the diamonds in Wafangdian, Liaoning Province
Meihua Chen,Fengxiang Lu,Jingru Di,Jianping Zheng
Chinese Science Bulletin , 2000, DOI: 10.1007/BF02909693
Abstract: The CL images show that the internal structures of the diamonds in Wafangdian, Liaoning Province is classified as three types: simple growth girdle zone, multi-stage growth complex girdle zone, and rare agate-like structure. These internal features reflect the complexity of growth processes of the diamonds. The FTIR analyses in micro area on diamond plates reveal the heterogeneity of the impurities of nitrogen and hydrogen. The variety of nitrogen contents and nitrogen aggregation states have been revealed not only in different diamonds from one kimberlite pipe but also in different zones of one diamond. The extent of conversion A defects to the aggregated B form is a function of the nitrogen aggregation temperature (T NA), mantle residence time (t MR), and nitrogen concentration of diamond. The interval of 0.6–0.7Ga from core to rim of diamond growth is obtained by using the FTIR curves and some geological data. The long period of diamond growth is identical with the feature in CL image.

Jingru ZHANG,Nan SONG,Xinshan JIA,Shanliang SUN
Chinese Journal of Lung Cancer , 2009,
Abstract: Background and objective Although there are increasing reports on localization of tracheal stem cells, the mechanism of proliferation and differentiation of tracheal stem cells remains unclear. Methods In this study, we developed an ex vivo model of murine tracheal epithelial injury and regeneration induced by 5-FU. The regenerationprocess of murine tracheal epithelium was observed and analyzed by morphological, immunofluorescence and microarray methods. Results After treatment with 5-FU, the differentiated mature cells were dead and desquamated. Only a few cells remained in G0 phase and located on the basement membrane. After being put back in normal culture media, the cells became flat, cubic and restored as pseudostratified epithelium at last. These G0 phase cells were ABCG2 positive. We detected the differences of stem cell genes between normal tracheal epithelial cells and regenerated epithelial cells at 24 h and 48 h after injured by 5-FU using stem cell differentiation gene microarray. At 24 h, 8 genes were up-regulated and 31 genes were down-regulated. At 48 h, 5 genes were up-regulated and 42 genes were down-regulated. Conclusion The differently expressed genes were mainly associated with cell cycle regulation, intercellular junction, FGF, BMP, Notch and Wnt signaling pathways, which suggested these alterations might be closely associated with the proliferation and differentiation of tracheal stem cells.
An Improved Model for Nucleation-Limited Ice Formation in Living Cells during Freezing
Jingru Yi, Xin M. Liang, Gang Zhao, Xiaoming He
PLOS ONE , 2014, DOI: 10.1371/journal.pone.0098132
Abstract: Ice formation in living cells is a lethal event during freezing and its characterization is important to the development of optimal protocols for not only cryopreservation but also cryotherapy applications. Although the model for probability of ice formation (PIF) in cells developed by Toner et al. has been widely used to predict nucleation-limited intracellular ice formation (IIF), our data of freezing Hela cells suggest that this model could give misleading prediction of PIF when the maximum PIF in cells during freezing is less than 1 (PIF ranges from 0 to 1). We introduce a new model to overcome this problem by incorporating a critical cell volume to modify the Toner's original model. We further reveal that this critical cell volume is dependent on the mechanisms of ice nucleation in cells during freezing, i.e., surface-catalyzed nucleation (SCN) and volume-catalyzed nucleation (VCN). Taken together, the improved PIF model may be valuable for better understanding of the mechanisms of ice nucleation in cells during freezing and more accurate prediction of PIF for cryopreservation and cryotherapy applications.
