The Effect of Online-to-Mobile Trust Transfer on the Foundation of Mobile Banking Trust  [PDF]
Bangjun Wang, Chu Shan
Communications and Network (CN) , 2013, DOI: 10.4236/cn.2013.51B025

The paper mainly studies the influences of trust transfer on the establishment of consumers’ initial trust. Based on the theory of signal transmission and self-efficiency, the study builds a trust transfer model aiming at the same subject between different environments. The results shows that when the consumers’ perceived change of environment is little, prior successful experiences will improve the consumers’ perceptions of self-ability, which probably lowers the effect of bank’s role on the establishment of initial trust. Therefore, banks should cultivate consumers’ perceptions of their relative advantages in the original environment and thus improve the consumers’ dependency in the new environment to avoid the loss of consumers and build a long-term relationship.

Arrhythmogenic right ventricular cardiomyopathy associated ventricular tachycardia misdiagnosed as idiopathic right ventricular outflow tract origin and its management  [PDF]
Xiangmin Shi, Yutang Wang, Zhaoliang Shan
Case Reports in Clinical Medicine (CRCM) , 2013, DOI: 10.4236/crcm.2013.28121
Abstract: Arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) is an autosomal dominant genetic form of cardiomyopathy (CM), which primarily affects the right ventricle (RV) and results in life threatening ventricular arrhythmias and sudden cardiac death (SCD). Diagnosis is difficult due to the broad spectrum of phenoltypic variations, especially in the early stage. Clinical suspicion should be raised in the setting of refractory ventricular tachycardia originating from the RV, and the final diagnosis could be made based on the combination of electrocardiography, echocardiography, cardiac magnetic resonance imaging (CMRI) and myocardial biopsy. Implantable cardioverter-defibrillator (ICD) implantation is an effective option for the treatment of ARVC.
A Routing Scheme for IPv6-Based All-IP Wireless Sensor Networks
Wang Xiaonan,Zhong Shan
International Journal of Distributed Sensor Networks , 2012, DOI: 10.1155/2012/750681
Abstract: The paper proposes a routing scheme for IPv6-based all-IP wireless sensor networks. The paper creates the IPv6 address structure and the IPv6 address configuration algorithm for all-IP wireless sensor networks. Based on the IPv6 address structure, the paper proposes the routing algorithm in the link layer for all-IP wireless sensor networks. In the routing scheme, a sensor node stores the next channel-sampling time of its neighbor nodes. In this way, only during the next channel-sampling time, a sensor node keeps active. and during any other time it returns to sleep. Therefore, the routing performance is improved. and the power consumption is reduced. Finally, the paper discusses the reduced IPv6 protocol stack performing the routing scheme. The routing scheme’s performance parameters are evaluated, including routing power consumption and delay, and the data results show the correctness and efficiency of the scheme. 1. Introduction With the dramatic growth of the WSN (wireless sensor network) application space and the emergence of a variety of new applications, WSN is required urgently to achieve the point-to-point communication with the Internet [1]. IPv6 has both abundant address resources and steady communication performance, so it becomes the ideal solution for the point-to-point communication between WSN and the Internet. In the IPv6-based all-IP WSN, a sensor node has a globally unique IPv6 address and uses the IPv6 protocol to achieve the point-to-point communication with the Internet. Compared to traditional WSN, all-IP WSN has more extensive applications space. For example, in the modern agriculture field, farm laborers can use the Internet to access all-IP WSN in the agricultural environment and acquire the real-time agricultural parameters for monitoring without geographical location constraint. At present, the following key technologies on implementing IPv6-based all-IP WSN need further researches [2, 3]. Address Autoconfiguration The IPv6 address auto-configuration is the important technical feature of IPv6, and it can configure an IPv6 address for each interface in the absence of intervention. The feature is consistent with WSN’s design goals, such as self-organization and self-configuration. At present, there are still some problems in implementing the existing IPv6 address auto-configuration strategies in WSN. For example, the stateful address configuration causes a lot of control messages, and the stateless address configuration needs to perform DAD (duplicate address detection) to ensure an address’s uniqueness. Therefore, it is

Subarea Tree Routing (STR) in Multi-hop Wireless Ad hoc Networks  [PDF]
Guikai LIU, Chunli SHAN, Gang WEI, Hongjiang WANG
Wireless Sensor Network (WSN) , 2009, DOI: 10.4236/wsn.2009.11006
Abstract: Subarea Tree Routing (STR), a new routing protocol for multi-hop wireless ad hoc networks, is proposed. The novelty of the STR protocol is to divide the whole network into many subareas constructed as a result of establishing subarea trees. Its main idea is to identify root nodes by manual configuration or auto-discovery process firstly, then the root nodes originate the process of establishing subarea trees, and finally each node either joins in a subarea tree or become an interconnect node. STR belongs to hierarchical routing protocol and does not attempt to consistently maintain routing information in every node. Furthermore, through the use of tree’s intrinsic routing function, the STR protocol exhibits hybrid behavior of proactive and on-demand routing protocols. We prove the correctness of STR, and our simulation results show that the pro-posed scheme achieves lower route discovery delays, lower route discovery load and better performance of normalized routing load in large, mobile, ad hoc networks as compared with AODV.

Purpose: To investigate the alteration of left ventricular function in subjects with persistent atrial tachyarrhythmia induced cardiomyopathy (TIC) undergoing radiofrequency ablation, and to study the pathogenesis and effective treatment of TIC. Methods: A total of 25 cases with persistent atrial tachyarrhythmia and impaired left ventricular systolic function were studied (16 men and 9 women, aged 53.3 ± 15.2 years), and all subjects underwent electrophysiological study and radiofrequency ablation of atrial tachyarrhythmia under the guidance of CARTO system during 2006.9-2011.8. Indexes related to cardiac function, including left ventricular end diastolic diameter (LVEDD), left ventricular ejection fraction (LVEF), New York Heart Association functional classification (NYHA class), 6 minutes walking test (6MWT), N-terminal pro-brain natriuretic peptide (BNP) and 24 hours average heart rate (AHR), were analyzed at the time point of 7 days, 3 and 6 months after the procedure as well as 1 day before ablation. Results: No refractory atrial arrhythmia recurred in all cases after ablation, compared with LVEDD (51.7 ± 4.5 mm), LVEF (39.0% ± 4.3%), number of patients with NYHA class IV and III (n = 17), 6MWT (212 ± 56 m), BNP (3622 ± 1860 ng/L) and AHR (112.5 ± 23.2 bpm) before ablation, the index of LVEDD (45.2 ± 3.3 mm; 41.7 ± 2.5 mm; 40.5 ± 3.1 m), BNP (2429 ± 1355 ng/L; 1530 ± 866 ng/L; 1300 ± 520 ng/L), total number of patients of NYHA class IV and III (n = 11; 3; 2) and AHR (73.3 ± 15.3 bpm; 68.7 ± 13.5 bpm; 66.3 ± 13.6 bpm) significantly decreased (P < 0.05), LVEF (45.6 ± 3.5%; 51.5 ± 2.7%; 53.5 ± 3.1%) and 6MWT (262 ±

47 m; 305 ± 37 m; 313 ± 41 m) greatly increased (P < 0.05in 7 days, 3 and 6 months after ablation respectively. There was a statistical difference between 7 days and 3 or 6 months after ablation in above-mentioned indexes (P < 0.05) except AHR (P > 0.05), no significant difference existed between 3 and 6 months in all indexes (P > 0.05). Conclusion: long-lasting atrial arrhythmia with rapid ventricular response could impair left ventricle function, which could be reversed within weeks after successful ablation and restoration of sinus rhythm.

Agricultural Sciences (AS) , 2013, DOI: 10.4236/as.2013.412101

The volatile flavor compounds of Jin Xiang garlic and Tai’an garlic in chemical composition were detected and analyzed and the contents of them were compared and determinated. The volatile constituents of Jin Xiang garlic and Tai’an garlic were compared and analyzed by automatic static headspace and gas chromatography-mass spectrometry. Qualitative analysis of samples was made through the analysis of gas chromatography-mass spectrometry and NIST mass spectral library computer retrieval, and quantitative analysis was made by using area normalization method. The analysis results show that the slight difference of the volatile flavor compounds was detected in different places of origin garlic and Jin Xiang garlic was detected more total sulfur-containing compounds than Tai’an garlic. Meanwhile, the contents of sulfur compounds of the fresh garlic were more than the stored garlic and there were significant differences between them. The tests results indicated that flavor substances’ types were slightly different between Jin Xiang garlic and Tai’an garlic, and regional differences cannot affect the garlic flavor substances type. Jin Xiang garlic has more obvious flavor substances than Tai’an garlic which play a decisive role in the garlic flavor, such as 1,3-dithiane, and allyl trisulfide and allyl disulfide and diallyl tetrasulphide. The result of this research indicates that Automatic static headspace and gas chromatography-mass spectrometry is a fast, easy, efficient and accurate method to analyze and identify the volatile flavor components of garlic.

The Technical Analysis on Upgrade and Coupling of Low-Quality Coal  [PDF]
Bin Zhao, Qiang Yao, Shan Lu, Qinggong Wang, Junfu Lv
Energy and Power Engineering (EPE) , 2014, DOI: 10.4236/epe.2014.613039
Abstract: Experimental study was conducted with regard to upgrading low-quality coal by low temperature pyrolysis technology and fluidization classification technology, which laid the theoretical foundation for research and development of low-quality coal upgrading process. Firstly, a pyrolysis pilot experiment of long-flame coal was performed and the optimum pyrolysis conditions were found. When the final pyrolysis temperature was 450?C and the residence time was 10 minutes, the content of semicoke volatile dry ash-free was about 22.89% and the content of semicoke ash was about 16.1%. More than 5% of the ash needs to be removed before entering the pyrolysis fluidized bed. Thus, classification tests were carried out to pick out the coal particles with the target size of 500 μm, using a gas-solid fluidized bed coal picker. It was found that the separating effect of coal particles was the most satisfactory when the inlet velocity at the bottom was 3.27 m/s. The percentage of particles with diameters less than 500 μm was as low as 28.7% in the coarse samples. Based on the test results, a novel process of low-quality coal upgrade and coupling was proposed, which realized the sorting, grading, drying and pyrolysis of low-quality coal through the multi-stage fluidized bed integrated process.
