Communications and Network (CN) , 2013, DOI: 10.4236/cn.2013.51B005
Abstract: In recent years, the ZigBee network has been rapid develop in smart home. In order to solve the interconnection problem between the ZigBee network and the internet in the smart home, a wireless home gateway based on embedded is designed and implemented in this paper. The gateway is made up of the main controller S3C2440, the ZigBee module JN5148 and the Wi-Fi module VT6656. It is capable of converting Wi-Fi protocol data or ZigBee protocol data, and transmitting them to each other. The paper describes the design and implementation process of the gateway hardware and software, introduces the Wi-Fi protocol data and the ZigBee protocol data conversion method, and solve the bottleneck caused by the two protocol different transmission rates. Then the performance of the gateway is tested, and the results indicate that the performance is stable, and the Wi-Fi–ZigBee gateway is completely meeting the needs of the smart home.
The Effect of Surface Friction on the Development of Tropical Cyclones

FANG Juan,TANG Jianping,WU Rongsheng,

大气科学进展 , 2009,
Abstract: When tropical cyclones (hereafter referred as TCs) are over the ocean, surface friction plays a dual role in the development of TCs. From the viewpoint of water vapor supply, frictional convergence and Ekman pumping provide a source of moisture for organized cumulus convection and is propitious to the spin-up of TCs. On the other hand, surface friction leads to a dissipation of kinetic energy that impedes the intensification of TCs. Which role is dominant in the developing stage of TCs is a controversial issue. In the present work, the influence of surface friction on the growth of TCs is re-examined in detail by conducting two sets of numerical experiments initialized with different cyclonic disturbances. Results indicate that, because of the inherent complexities of TCs, the impact of surface friction on the evolution of TCs can not be simply boiled down to being positive or negative. In the case that a TC starts from a low-level vortex with a warm core, surface friction and the resultant vertical motion makes an important contribution to the convection in the early developing stage of the TC by accelerating the build-up of convective available potential energy (CAPE) and ensuring moisture supply and the lifting of air parcels. This effect is so prominent that it dominates the friction-induced dissipation and makes surface friction a facilitative factor in the spin-up of the TC. However, for a TC formed from a mesoscale convective vortex (MCV) spawned in a long-lasting mesoscale convective system (MCS), the initial fields, and especially the low-level humidity and cold core, enable the prerequisites of convection (i.e., conditional instability, moisture, and lifting), to be easily achieved even without the help of boundary-layer pumping induced by surface friction. Accordingly, the reliance of the development of TCs on surface friction is not as heavy as that derived from a low-level vortex. The positive effect of surface friction on the development of TCs realized through facilitating favorable conditions for convection is nearly cancelled out by the friction-induced dissipation. However, as SST is enhanced in the latter case, the situation may be changed, and different development speeds may emerge between model TCs with and without surface friction considered. In short, owing to the fact that TC development is a complicated process affected by many factors such as initial perturbations, SST, etc., the importance of surface friction to the intensification of TCs may vary enormously from case to case.
Predicting Adjuvant Chemotherapy Outcome by Simultaneous Analysis of Thymidylate Synthase Expression and p53 Nuclear Accumulation in Colorectal Cancer  [PDF]
Zihuan Yang, Dandan Huang, Lekun Fang, Xingzhi Feng, Huanliang Liu, Lei Wang, Jianping Wang
Journal of Cancer Therapy (JCT) , 2015, DOI: 10.4236/jct.2015.65048
Abstract:

Studies have shown that the tumor suppressor gene p53 may regulate thymidylate synthase (TS) activity in colorectal cancer (CRC) cells, hence attributed to chemo-resistance to 5-flurouracil in CRC. In this study, a total of 299 primary CRC patients who underwent surgery alone or received an adjuvant 5-FU-based chemotherapy were retrospectively studied. TS expression and p53 nuclear accumulation on paraffin embedded primary tumor tissue arrays were immunohistochemically assessed, and their relationship to patient overall survival (OS) and disease free survival (DFS) were analyzed. No correlation was found between TS and p53 expression. p53 nuclear accumulation was significantly correlated with tumor location. In all, multivariate analysis shows that TNM stage is a good indicator of patient survival. TS or p53 is not an independent prognostic or predictive factor in the CRCs. In chemotherapy-treated group, simultaneous analysis of TS and p53 indicates patients in the p53-/TS- or p53+/TS+ group have significant better OS and DFS than the group p53-/TS+ or p53+/TS- (P < 0.01). Thus, our study suggests that simultaneous evaluation of both TS and p53 can help to predict the therapeutic effect of CRCs with 5-FU-based adjuvant chemotherapy.

Improved Quantum-Behaved Particle Swarm Optimization  [PDF]
Jianping Li
Open Journal of Applied Sciences (OJAppS) , 2015, DOI: 10.4236/ojapps.2015.56025
Abstract: To enhance the performance of quantum-behaved PSO, some improvements are proposed. First, an encoding method based on the Bloch sphere is presented. In this method, each particle carries three groups of Bloch coordinates of qubits, and these coordinates are actually the approximate solutions. The particles are updated by rotating qubits about an axis on the Bloch sphere, which can simultaneously adjust two parameters of qubits, and can automatically achieve the best matching of two adjustments. The optimization process is employed in the n-dimensional space [-1, 1]n, so this approach fits to many optimization problems. The experimental results show that this algorithm is superior to the original quantum-behaved PSO.

Open Journal of Applied Sciences (OJAppS) , 2015, DOI: 10.4236/ojapps.2015.56024
Abstract: In this paper, a novel neural network is proposed based on quantum rotation gate and controlled- NOT gate. Both the input layer and the hide layer are quantum-inspired neurons. The input is given by qubits, and the output is the probability of qubit in the state . By employing the gradient descent method, a training algorithm is introduced. The experimental results show that this model is superior to the common BP networks.

Board Advising, Risk-Taking, and Firm Performance  [PDF]
Jianping Li
Journal of Financial Risk Management (JFRM) , 2016, DOI: 10.4236/jfrm.2016.53015
Abstract:
The corporate risk-taking has caught public attention due to the global financial crisis. Using a sample of listed companies in China from 2008 to 2015, this paper investigates how the role of board advising affects corporate risk-taking and the possible economics consequences of risk-taking. The empirical results show that the percentage of advisory directors is positively associated with the level of corporate risk-taking, and the interaction of the percentage of advisory directors and risk-taking is positively correlated with the future firm performance. However, these effects are not significant at all in the state-owned enterprises due to government’s interference.

Abstract: A regional air--sea coupled model, comprising the Regional Integrated Environment Model System (RIEMS) and the Princeton Ocean Model (POM) was developed to simulate summer climate features over East Asia in 2000. The sensitivity of the models behavior to the coupling time interval (CTI), the causes of the sea surface temperature (SST) biases, and the role of air--sea interaction in the simulation of precipitation over China are investigated. Results show that the coupled model can basically produce the spatial pattern of SST, precipitation, and surface air temperature (SAT) with five different CTIs respectively. Also, using a CTI of 3, 6 or 12 hours tended to produce more successful simulations than if using 1 and 24 hours. Further analysis indicates that both a higher and lower coupling frequency result in larger model biases in air--sea heat flux exchanges, which might be responsible for the sensitivity of the coupled models behavior to the CTI. Sensitivity experiments indicate that SST biases between the coupled and uncoupled POM occurring over the China coastal waters were due to the mismatch of the surface heat fluxes produced by the RIEMS with those required by the POM. In the coupled run, the air--sea feedbacks reduced the biases in surface heat fluxes, compared with the uncoupled RIEMS, consequently resulted in changes in thermal contrast over land and sea and led to a precipitation increase over South China and a decrease over North China. These results agree well observations in the summer of 2000.

Abstract:

Predicting the possible impacts of future climate change on cropping systems can provide important theoretical support for reforming cropping system and adjusting the distribution of agricultural production in the future. The study was based on the daily data of future B2 climate scenario (2011-2050) and baseline climate condition (1961-1990) from high resolution regional climate model PRECIS (~50 km grid interval). According to climatic divisions of cropping systems in China, the active accumulated temperature stably passing the daily average temperature of 0°C, the extreme minimum temperature and the termination date passing the daily average temperature of 20°C which were justified by dominance as a limitation of different cropping systems in zero-grade zone were investigated. In addition, the possible trajectories of different cropping systems in China from 2011 to 2050 were also analyzed and assessed. Under the projected future B2 climate scenario, from 2011 to 2050, the northern boundaries of double cropping area and triple cropping area would move northward markedly. The most of the present double cropping area would be replaced by the different triple cropping patterns, while current double cropping area would shift towards areas presently dominated by single cropping systems. Thus the shift of multiple cropping areas would lead to a significant decrease of single cropping area. Compared with China’s land area, the percentage cover of single cropping area and double cropping area would decrease slowly, while percentage cover of triple cropping area would gradually increase.
