Published: May 2014

We previously reported that transcription factor XBP1S is upregulated during chondrocyte differentiation and demonstrates the temporal and spatial expression pattern during skeletal development. Herein, we found that XBP1S stimulates chondrocyte differentiation from mesenchymal stem cells in vitro and endochondral ossification ex vivo. In addition, XBP1S activates granulin-epithelin precursor (GEP), a growth factor known to stimulate chondrogenesis, then enhances GEP-stimulated chondrogenesis and endochondral bone formation. Collectively, these findings demonstrate that XBP1S positively regulates endochondral bone formation by activating GEP chondrogenic growth factor.

Authors: Qin Chun Lei , Huang Ming , Yang Jing Jing , Shen Li , Liang Ying Hong
Published: May 2014

This paper introduces a feasible patch antenna to generate OAM-carrying radio beams. Eight identical printed dipole antennas with microstrip balun feedline are arranged in an octahedron cylindrical substrate. Every printed dipole is fed with unit amplitude but with a successive phase difference from element to element. We can change the phase difference at the steps of 0, ±45o, ±90o, and ±135o to obtain mode numbers 0, ±1, ±2, and ±3. Simulation shows that the OAM states of ±1, ±2 and-3 achieve the expected results well, while the state of +3 produce a deviation due to the radiation difference of the designed antenna element and traditional tripole antenna. Furthermore, we achieve the impedance matching of every port and increase the directivity of the antenna. Thus, the proposed antenna is a promising candidate to generate OAM in engineering.

“Threshold-Deciding” Policy in Distributed Multiuser Opportunistic Spectrum Access
Authors: Wang Yu Meng , Shen Liang , Gao Xiang , Xu Cheng Long , Li Xiao Ya , Lin Yong
Published: May 2014

This paper studies the problem of distributed multiuser Opportunistic Spectrum Access based on Partially Observable Markov Decision Process (POMDP). Due to the similarity of spectrum environment, secondary users may choose the same channel adopting their own single user approach, which leads to collision. Referring to the previous works, we propose a more flexible and adaptive policy named “threshold-deciding”. Firstly, the SU gets a channel by adopting the random policy. Secondly, the SU decides whether to sense the channel by comparing the available probability with the given threshold. The policy not only decreases the collisions among SUs but also reduces the consumption of time and energy. The simulation results shows that the upgrade of performance is up to 100% compared with the existing random policy, which demonstrate the advantage of the proposed policy.

Authors: Leng Yan , Qi Guang Hui , Xu Xin Yan , Wang Xiao Peng , Li Deng Wang
Published: May 2014

Currently, most researchers select clustering-based algorithms to generate the initial training set for active learning. Considering that for such algorithms, a single clustering is not stable, we propose an initial training set selection algorithm which combines multi-clustering results to select samples. Specifically, after each clustering, it delimits several representative regions. If a sample falls into its corresponding representative region, then the algorithm casts a vote for it to mark that it is a potential representative sample. Finally, after several clustering, the samples with the most votes are selected. Experimental results show that our algorithm can efficiently select the informative samples, and can make the classifier have a more stable performance.

A 1000 hour hydrotreating experiment was performed to investigate the hydrotreating behavior of heteroatom compounds (first stage) and HDM catalyst deactivation (second stage) using Venezuela De-Asphalted Oil. The effect of reaction severity on impurities removal was the expected one, the deeper the hydrotreating degree, the higher the conversion of impurities. The Characterization of spent HDM catalyst shows that the content of coke deposition on spent HDM catalyst is only 4 wt% while that of metal is more than 30 wt%. Vanadium compounds in DAO with less diffusion resistance can deposit inside of the HDM catalyst grain. Lower coke formation also retard the HDM catalyst by keeping the diffusion pores and active cites. The removal of asphaltenes largely improved the stability of the HDM catalyst.

In computer graphics, Stereo Vision has been a research hotspot for many years, and it is been widely used in many areas. Stereo Vision is a technique which utilizes computer to simulate human eye system. In order to achieve this simulation, two main problems need to be solved: camera calibration and stereo matching. We focus on stereo matching in this paper. After years of development some achievements have been made in stereo matching, but some problems remain unsolved. The two most important things concerned in stereo vision trend to be contradictory: accuracy and efficiency. This paper presents a method called Advanced-Census which is a good combination of SAD and Census. When finding corresponding pixel in left and right image, SAD can get high accuracy with low speed and Census have the opposite result. Advanced-Census has advantages of both SAD and Census. It retains the speed of Census while having the accuracy of SAD. Although it has the speed of Census but not enough for practical applications, so we speed up Advanced-Census using multi-thread technique and edge detection. After speeding up, Advanced-Census gets nearly real-time performance.

Published: May 2014

The computing power of mobile devices makes it possible to transplant the applications which run on PCs to mobile devices. However, the power is still too weak to meet the requirements for some kinds of applications which are highly in real-time. In augmented reality applications, feature extraction, as well as feature matching is critical. In this paper .we focus on the part of feature extraction, and modify SURF as an example to fit the hardware characteristics of mobile devices. To solve the mismatch between the small cache size and the data access pattern. We proposed the content-aware tiling based SURF according to the small cache capacity. Experiments show that the accelerated SURF achieves a 1.5x-1.7x speedup without sacrificing recognition accuracy.

Authors: Chen Tian Xiao , Li Chun Mei , Cheng Nan Pu , Jia Hui Na
Published: May 2014

The direct extrusion process by using a newly designed die with different angle and feeder plate numbers has been simulated to systematically investigate the effects of different geometric parameters angle and feeder plate number on the strain distribution, the load and the axial hole defect. The simulation results show that the extrusion process with multiple feeder plate die is similar to that of the extrusion for many times. The angle and feeder plate make the material flow more fluently and ameliorate the axial hole defect. The larger angle reduces the load while the feeder plate increases it. Suitable geometrical parameters can significantly enhance strain in workpiece.
