Published: August 2014

This work deals with a methodology to evaluate residual stresses within microelectronic devices by using MOS (Metal Oxide Semiconductor) rosette stress sensors. The stress tensor was evaluated by carrying out electrical measurements on test vehicle: the bridge from electrical to stress values was ensured by the piezoresistive relations and, prior to further in-house calibration, coefficients from literature were employed. For correlation purpose, numerical simulations were performed in order to evaluate stresses induced by TSV (Through Silicon Via). In this paper, the whole framework is described, and stress fields evaluated from in-situ electrical measurements on CMOS65 rosette sensor are compared to simulated ones. Some of the ultimate targets of this work are to develop a validated framework to deeply understand TSV induced thermo-mechanical stresses and to allow design rules definitions for products reliability and transistor performances.

Published: August 2014

Robotics has been widely applied in all kinds of such fields as production, service and special operation, but its integrated intelligence has been limited by the capability of equipped chips. To improve the capability, robots use the services offered by background clusters through the network. The load balancing in cloud robot, in fact, describes the problem of assigning tasks to the front or the back. So far, the load balancing strategy is only for the data server and metadata server load balancing, and does not take the load balancing of task between client and server. In this paper, we put forward an adaptable load balancing of task (ALBT), which is based on the client’s running condition and network delay cost, including basic load balancing of task (BLBT) and dynamic adjusting algorithm (DAA). The basic task load balancing can balance task between robot and cluster system according to the current condition of robot and the complexity of task. In addition, the dynamic adjusting algorithm can in real time transfer task load between them using an event mechanism. ALBT adjusts itself to the environment which can meet robot’s requirements with good performance and robustness.

Collected root exudates were subjected to the soil with winter wheat cultivation and wasteland. Soil available nutrition contents, enzyme activities and microorganism population were determined. The results showed that the root exudates of M. jalapa could significantly reduce the contents of the available K, available N and P in soil under the higher input. But higher input of M. jalapa root exudates significantly improved ( P<0.05) the organic matter in soil. The exudates could reduce the soil enzyme activities except for protease, and which was elevating along with the raising input. The difference was significant when the input of root exudates was middle level. But higher input of M. jalapa root exudates significantly enhanced ( P<0.05) the activity of protease in soil. The amount of bacteria and actinomycetes in treatment LC and HC showed an evident reduction in the population of living microorganisms. However, the population of fungi increased under treatment LC and MC, which was almost twice as much as that in corresponding control when the root exudates was middle concentration. But the fungi population in treatment HC was significantly lower than that in corresponding control.

Authors: Long Zi Yuan , Han Xu , Wang Wen Jun
Published: August 2014

Human behavior is one kind of complicated phenomena. Comprehensive and profound understanding of their behavioral characteristics has been the direction of the tireless efforts of people. In recent years, studies have shown that: if the time series of human behavior is a Poisson process, its probability distribution is exponential distribution interval. However, currently a number of empirical analyses show that: some of the probability distribution of the interval of events triggered by human behavior are Power-law distribution and the process is an intermittency process. In this paper, based on a statistical analysis of about 1300000 user log of TJU-ACM from 2004 to 2013, we found that distribution of the interval of submit time of users follows a power law with an exponent characteristic, which is a difference from the analysis results of the previous wording. After investigation, we knew the reason for this result is that the answer to the question of ACM online is driven by a specific interaction of interest. It also further demonstrates that for the time series of some natural phenomena and human behavior, its time domain features are shown a strong episodic, and its distribution characteristics are driven by specific factors.

Typical arrest at G2/M phase was induced, and the apoptosis rate of U87-MG cells was significantly higher in the 20S-Rg3 treatment group than in the control group. Electrophysiological results showed that 80 μmol/L 20S-Rg3 substantially inhibited voltage-gated K+currents of U87-MG cells. Together, these results suggest that the suppression of voltage-gated K+currents might play an important role in the 20S-Rg3-induced cell death, and these new findings provide useful data for further study of the antitumor effect of 20S-Rg3.

Authors: Wang Chun Mei , Chen Bao Feng
Published: August 2014

Research achievements of the ASTP Policy-Oriented cannot generate directly economic benefit, social benefit and ecological benefit. It would realize benefit of ASTP only if the outputs can be transformed practical productive forces. In this paper, the mechanism and pathway of achieving benefit of ASTP is analyzed deeply based on the logical framework model. Then the empirical studies shows that the inputs (research investment) have positive correlation with outputs (research achievement), extension and outcomes (changes in productivity). Although the inputs have a certain influence to agricultural economics, it mainly affects indirectly agricultural development by research achievements and extension. Therefore, the benefits of ASTP should not be evaluated according by inputs/outputs methods. We must analyze and assess the anticipated chain of cause/effect relationships of ASTP based on the program “theory-driven” approach. It can promote agricultural research and extension projects to integrated closely, at the same time the benefit of ASTP can be improved greatly.

Published: August 2014

The processes for absorbing knowledge become an essential element for innovation and competitiveness in enterprises. Despite the huge growth in the absorptive capacity literature, a method gap still remains about a certain ambiguity in the measurement of the construct specifying its theoretical domain. The aim of this paper is to contribute to the research on absorptive capacity through the construction of four aspects, based on a thorough analysis of the literature and field research, to measure the key components of the absorptive capacity construct: acquisition capacity, assimilation capacity, transformation capacity and application capacity. The evaluation model based on entropy weights and interval TOPSIS is established which focuses on measuring absorptive capacity. The practical case study is conducted to illustrate the application of the proposed method for the knowledge absorptive capacity and verify effectiveness and feasibility.

Published: August 2014

Aimed at combination weighting in multiple attribute decision making, a new approach for combining different weighting vectors is proposed. The proposed approach considers the randomicity of weights themselves and the consistency among weighting vectors, constructs a constrained weighted relative entropy model. Aimed at the disadvantage in the TOPSIS based on Euclidean distance, the TOPSIS based on Mahalanobis distance is adopted to solve the coefficients of optimal weight vector. Finally, an example is conducted and the results show the proposed approach is effective and is more reasonable than three other combination approaches.

Given the problems associated with the escalation in methamphetamine (METH) use, the identification of more effective treatment strategies is essential.l-stepholidine (l-SPD) is an alkaloid extract of the Chinese herb Stephania intermedia with dopamine D1 receptor partial agonistic and D2 receptor antagonistic dual actions. The unique pharmacological profile ofl-SPD suggests thatl-SPD may be effective for the treatment of METH addiction. The aim of this study was to characterize the effect ofl-SPD on METH self-administration on a fixed-ratio 1 schedule. We found that 5 and 10 mg/kg ofl-SPD attenuated METH self-administration behavior. These results demonstrate thatl-SPD which possesses dual actions on dopamine D1 and D2 receptors, attenuates METH self-administration on a fixed-ratio 1 schedule.
