Intergovernmental Allocation of Public Resources, Fiscal Decentralization and Economic Growth
Yue Lai,Tianzhu Cheng
International Journal of Information Engineering and Electronic Business , 2011,
Abstract: Incorporating a two-level government structure into an endogenous growth model, we discussed the growth impacts of different intergovernmental allocation of public resources, i.e. intergovernmental transfer payments and the power of revenue autonomy of the lower-level government, along with fiscal decentralization. we showed that (1) there was an “Inverted U-shaped” relationship between fiscal decentralization and economic growth; (2) Different intergovernmental allocation of public resources does not affect the “Inverted U-shape” relationship between fiscal decentralization and economic growth.

Open Journal of Earthquake Research (OJER) , 2014, DOI: 10.4236/ojer.2014.32010
Abstract: Objective: “5.12” Wenchuan Earthquake killed 70,000 people and left more than 90,000 people injured seriously. This study was to analyze the wound features and early treatments in Wenchuan earthquake victims and investigate treatment strategies in major disasters, to provide a reference to future disaster rescue. Methods: Total of 1420 earthquake patients who were admitted to Deyang People’s Hospital, Sichuan Province from May 12-30, 2008 were enrolled in the study. The wound features and early treatment were retrospectively analyzed. Results: Among 1420 patients, there were total 1821 injuries. In which, there were 1089 cases with single site injury (76.69%) and 331 cases with multiple injury (23.31%); injuries of limb, body surface and soft tissue were more than that of other sites; injury of single site was larger than that of multi-site (P < 0.01); most of the earthquake patients were admitted to hospital within 2 days after earthquake (68.80%), whose number was more than those at other times (P < 0.01); the number of the earthquake patients in 19 - 45 age group was more than that of other groups (P < 0.01); most of patients were treated within 12 hours after injury (P < 0.01). Conclusion: In disaster rescue, rescue speed is the key point. And the “golden time” and emphases of rescue should be within 2 days after earthquake; the principle of damage control surgery should be followed in the rescue. Enhancing mutual and self help practice and first-aid training at usual times may save more lives.

Health (Health) , 2009, DOI: 10.4236/health.2009.12014
Abstract: Objective: To observe the concentration of se-rum homocysteine in intellectuals and the re-lated influential factors. Methods: The concen-trations serum homocysteine and saliva cortisol were measured in 138 intellectuals from three cities, Tianjin, Guangzhou and Chengdu in China. All the subjects had senior titles of tech-nical post, aged 40-69 years. Results: The mean value of serum homocysteine concentration in intellectuals was 20.6±0.8μmol/L, higher than the reference value. With the increase of cortisol levels the homocysteine concentrations rise (P <0.05). The mean value of homocysteine con-centration was highest in 40-49 years old group. Men had higher homocysteine level than women in this investigation. According to the mean value of homocysteine concentration among different cities, Tianjin was highest, Chengdu medium, Guangzhou lowest. Conclusion: The serum homocysteine concentration of intellec-tuals is higher than the reference value. The stress level, gender and resident cities might contribute to the differences in serum homo-cysteine concentration in Chinese intellectuals.
Performance Improvement of the LM Device and Its Application to Precise Measurement of Motion Trajectories within a Small Range with a Machining Centre  [PDF]
Hua Qiu, Yong Yue, Akio Kubo, Chao Lin, Kai Cheng, Dehong Huo, Dayou Li
Modern Mechanical Engineering (MME) , 2012, DOI: 10.4236/mme.2012.23010
Abstract: In order to apply the LM device previously developed to precisely measuring small motion trajectories located on the different motion planes, three major improvements are successfully performed under the condition of completely maintaining the advantages of the device. These improvements include 1) development of a novel connection mechanism to smoothly attach the device to the spindle of a machining centre; 2) employment of a new data sampling method to achieve a high sampling frequency independent of the operating system of the control computer; and 3) proposal of a set-up method to conveniently install the device on the test machining centre with respect to different motion planes. Practical measurement experiment results with the improved device on a machining centre sufficiently demonstrate the effectiveness of the improvements and confirm several features including a very good response to small displacement close to the resolution of the device, high precision, repeatability and reliance. Moreover, based on the measurement results for a number of trajectories for a wide range of motion conditions, the error characteristics of small size motions are systematically discussed and the effect of the movement size and feed rate on the motion accuracy is verified for the machining centre tested.
Effect of Microwave Sintering on the Microstructure and Dielectric Properties of Bi2O3-Doped (Ba0.6Sr0.4)(Ti0.94Cu0.06)O3 Ceramics  [PDF]

New Journal of Glass and Ceramics (NJGC) , 2014, DOI: 10.4236/njgc.2014.41001

The effects of microwave sintering on the sintering behaviour, microstructure and dielectric properties of Bi2O3-doped (Ba0.6Sr0.4)(Ti0.94Cu0.06)O3 (BSTC) ceramics were investigated. The microstructure and dielectric properties of a BSTC ceramic were also studied given different amounts of Bi2O3 doping. Microwave heating with sintering temperatures below 1000°C significantly improves the densification of Bi2O3-doped BSTC ceramics. The BSTC ceramic with 1 wt% Bi2O3 addition sintered at 950°C in air for 30 min exhibited dielectric properties of er = 3756, dielectric loss of tanδ = 7 × 10-3 and bulk density > 96% of theoretical density.

Abstract: Red rice gains popularity as a functional crop owing to its high polyphenols content and antioxidant activity. However, active components are discarded in common milling. Superfine ground technology was employed in this paper. To evaluate the influence of superfine ground processing on the physicochemical properties and functional effect of red rice (Oryza sativa L.), four powders with the size of 156.74 μm, 69.53 μm, 26.35 μm, and 10.68 μm were prepared by superfine grinding technology in this paper. Results showed that the size was smaller for red rice powders, greater for the bulk density (from 0.624 g/ml to 0.745 g/ml), and smaller for the angle of repose (from 74.67° to 61.41°) and slide (from 38.99° to 26.42°). The values of water solubility index, water holding capacity and enzymatic digestibility by α-amylase significantly increased with the decreasing particle size (P < 0.05). In addition, antioxidant activity and phenolic content were enhanced by superfine ground. These results indicated that superfine ground would improve the physicochemical and functional properties of red rice, which was helpful to promote the overall quality and healthy effect of foods containing red rice.

Density Sensitive Hashing
Yue Lin,Deng Cai,Cheng Li
Computer Science , 2012,
Abstract: Nearest neighbors search is a fundamental problem in various research fields like machine learning, data mining and pattern recognition. Recently, hashing-based approaches, e.g., Locality Sensitive Hashing (LSH), are proved to be effective for scalable high dimensional nearest neighbors search. Many hashing algorithms found their theoretic root in random projection. Since these algorithms generate the hash tables (projections) randomly, a large number of hash tables (i.e., long codewords) are required in order to achieve both high precision and recall. To address this limitation, we propose a novel hashing algorithm called {\em Density Sensitive Hashing} (DSH) in this paper. DSH can be regarded as an extension of LSH. By exploring the geometric structure of the data, DSH avoids the purely random projections selection and uses those projective functions which best agree with the distribution of the data. Extensive experimental results on real-world data sets have shown that the proposed method achieves better performance compared to the state-of-the-art hashing approaches.
Hyaluronan Immobilized Polyurethane as a Blood Contacting Material
Feirong Gong,Yue Lu,Hui Guo,Shujun Cheng,Yun Gao
International Journal of Polymer Science , 2010, DOI: 10.1155/2010/807935
Abstract: Hyaluronan (hyaluronic acid, HA) was immobilized onto the surface of amino-functionalized polyurethane films with the goal of obtaining a novel kind of biomaterial which had the potential in blood-contacting applications. The amino-functionalized polyurethane was prepared by synthesized acidic polyurethane whose pendant carboxyl groups were treated with an excess amount of 1,3-diaminopropane in the presence of N,N-carbonyldiimidazole (CDI). Attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR), Raman spectroscopy (RS), scanning electron microscopy (SEM), and water contact angle measurement were used to confirm the surface changes at each step of treatment, both in morphologies and chemical compositions. APTT and PT results showed that HA immobilization could prolong the blood coagulation time, thus HA-immobilized polyurethane (PU-HA) exhibited improved blood compatibility. Cytotoxicity analysis showed that the PU-HA films synthesized in this study were cytocompatible and could support human vein endothelial cells (HUVECs) adhesion and proliferation. 1. Introduction Thermoplastic polyurethanes (PU) have been widely used for various biomedical applications due to their excellent mechanical properties and proper blood compatibility. Recently, much effort has been focused on polyurethanes as blood-contacting materials, such as cardiovascular biomaterials, hemodialysis blood line sets, central venous catheters (CVC), and IV bags [1, 2]. However, surface-induced thrombosis, protein fouling, and cytocompatibility have become the major drawbacks that hinder their further biomedical applications as blood-contacting materials. Surface modification is an effective approach to improve the blood compatibility, the size, shape, and mechanical properties of the original material maintained. Many studies have been performed on producing a blood-compatible surface by tailoring with poly(ethylene glycol) (PEG) [3, 4], heparin [5, 6], heparin-like [7–9], phospholipid polymer [10–13], hirudin [14], sulfobetaine [15, 16], and so on. Although many hydrogels or hydrophilized surfaces exhibit good blood compatibility, most of these are not truly antithrombogenic but only antithromboadhesive [17] as they curtail or inhibit platelets and blood cell adhesion rather than prolong the coagulation time. Hyaluronan (HA), a linear biopolymer naturally abundant in mammalian tissues, is composed of repeating units of N-acetyl-D-glucosamine and D-glucuronic acid, linked by -(1,4) and -(1,3) glycosidic junctions [18]. HA has been identified as a nontoxic,
Lecithin-Linker Microemulsion Gelatin Gels for Extended Drug Delivery
Xiao-Yue Xuan,Yu-Ling Cheng,Edgar Acosta
Pharmaceutics , 2012, DOI: 10.3390/pharmaceutics4010104
Abstract: This article introduces the formulation of alcohol-free, lecithin microemulsion-based gels (MBGs) prepared with gelatin as gelling agent. The influence of oil, water, lecithin and hydrophilic and lipophilic additives (linkers) on the rheological properties and appearance of these gels was systematically explored using ternary phase diagrams. Clear MBGs were obtained in regions of single phase microemulsions (μEs) at room temperature. Increasing the water content in the formulation increased the elastic modulus of the gels, while increasing the oil content had the opposite effect. The hydrophilic additive (PEG-6-caprylic/capric glycerides) was shown to reduce the elastic modulus of gelatin gels, particularly at high temperatures. In contrast to anionic (AOT) μEs, the results suggest that in lecithin (nonionic) μEs, the introduction of gelatin “dehydrates” the μE. Finally, when the transdermal transport of lidocaine formulated in the parent μE and the resulting MBG were compared, only a minor retardation in the loading and release of lidocaine was observed.
