Inquiry into FDI Pattern of China and the Economies along the Belt & Road  [PDF]
Junrong Liu, Yuan Liu
Technology and Investment (TI) , 2018, DOI: 10.4236/ti.2018.93012
Abstract: This paper empirically analyzes the FDI Pattern of China and the other economies along the Belt & Road Initiative. The analysis results show that 1) the mutual FDI between China and the economies along the Belt & Road regions has continuously increased, and the mutual dependence of FDI continues to deepen, but there still is some imbalance existing in FDI dependence and distribution; 2) the Belt & Road Initiative has its objective material basis and subjective willingness for regional FDI cooperation; 3) China and the other economies along the Belt & Road Initiative, need to further utilize the complementary advantages in their industrial and economic structures for deepening the bilateral and multilateral FDI cooperation; 4) China and the countries along the Belt & Road need to clear the investment barriers and achieve a win-win situation for international investment and cooperation, in order to promote the continuous deepening of the Belt & Road Initiative and realize regional common prosperity.
Principal Factors Affecting IDBT Evolution  [PDF]
Changqing Liu, Haili Yuan
Journal of Service Science and Management (JSSM) , 2011, DOI: 10.4236/jssm.2011.44050
Abstract: Studies on Italian Double-entry Bookkeeping Thought (IDBT) evolution are seldom found in such aspects as accounts with persons (AP), accounts with goods (AG), and accounts equilibria (AE), etc., so we studied IDBT evolution in the aspects stated above and the principal factors for IDBT evolution, including their selection, contribution and sequence in this thesis. By our analysis, IDBT evolved in such aspects as accounts with persons (AP), accounts with goods (AG), loss and net income accounts (LNIA), capital accounts (AC) and accounts equilibria (AE), etc., and ripened in the period of 1430-1482. Principal factors affecting IDBT evolution can be ordered by contribution as follows: social conditions (SCS3) and relationships between supply and demand of accounting thought (RBSDAT2). And our related advice is as follows: governments should adopt appropriate policy, and help to build proper social conditions and strengthen the relationships between supply and demand of accounting thought to promote the evolution of accounting thought. Especially as to social conditions, IDBT evolution is mainly owing to external causes from the outside of Italy. Once the outside motive disappeared, IDBT would lose the strong power of evolution and slow down its pace. So governments should place more emphases on building proper social conditions by encouraging internal powers from the inside of Italy.
Intracranial aneurysm with neck indistinguishable from surrounding artery branches by cerebral angiography  [PDF]
Zheng Liu, Bangqing Yuan
World Journal of Neuroscience (WJNS) , 2013, DOI: 10.4236/wjns.2013.34040

The aim of this study is to examine morphology of intracranial aneurysm with neck indistinguishable from surrounding artery branches by cerebral angiography and discuss whether such aneurysms can be treated by interventional embolization. 6 patients who had not been treated by embolization due to irregular wide-necked aneurysms indistinguishable from surrounding artery branches by cerebral angiography received craniotomy for aneurysm clipping. The operations succeeded. Morphologically, neck width and location of the aneurysms were carefully observed and photographed from different directions and multi-angles during operation. The intraoperative findings were compared with the preoperative CTA and DSA images. Walls of the 6 patients’ aneurysms tightly clung to or adhered to surrounding branches and oppressed the branches into arcs, similar to the aneurysm walls in shape, and arterial branches and aneurysm walls suffered from segmental adhesion. In addition, abnormalities of communicating arteries to vary degrees were observed in 4 patients. However, after successful surgical clipping, it was revealed that the aneurysms would have been better treated by embolization since they are basically saccular aneurysms with regular sizes. Deformations in preoperative angiography may be due to anatomical variations of surrounding vessels near the aneurysms, aneurysm wall oppression or incomplete adhesion of surrounding arterial branches. Such deformations can be recognized by careful observation in preoperative angiography from different directions and multi-angles.


High-Power 30-Element Helical Antenna Array  [PDF]
Yuan Liang, Qingxiang Liu
Journal of Computer and Communications (JCC) , 2018, DOI: 10.4236/jcc.2018.612004
A new radial-line helical array (RLHA) using dual-branch helical antennas has been designed for improving the power capacity of RLHAs. The helical element is cavity-backed to lower the mutual coupling and its power capacity is higher than the conventional ones. The components of the proposed array are discussed and the power capacity is obtained by simulation. Compared with the typical RLHAs, the proposed sub-array has not only higher power capacity but also uses fewer elements. Experimentally, the measured results of an array prototype indicate that high gain as well as circular polarization has been successfully achieved.
Social Cognitive Neuroscience Perspective for Unification Psychology  [PDF]
Wangbing Shen, Chang Liu, Yuan Yuan
Psychology (PSYCH) , 2011, DOI: 10.4236/psych.2011.28128
Abstract: As a direct part of these disciplines which focuses on human’s soul and mind, psychology has a history of more than one hundred years. However, there are still many people who have lots of doubts for psychology, especially on the division and integration of psychology which dates back to Spence (1987). Many studies in the past have sought for many paradigms to integrate psychology, but they failed, such as cognitive psychology paradigm. One challenge to the traditional perspective comes from works of social cognitive neuroscience. More and more specific studies showed that social cognitive neuroscience can integrate psychological science. Therefore, increasing psychologists, including theoretical psychologists focus their sights on social cognitive neuroscience. The article gave an overview analysis to those problems, including the integration from social cognitive neuroscience is possible and its prospect framework of integration
Analysis and Evaluation of Organizational Change Approaches

International Journal of Business and Management , 2009, DOI: 10.5539/ijbm.v4n12p234
Abstract: Organizational change is the trend for the further development and which been explained is the enduring quest of scholars in many disciplines. Prescriptive approach and emergent approach are two main types of models for organizational change. The ‘Seven S Framework’ from Peters and his colleague to show the interrelationships between different aspects of corporate strategy. Mintzberg developed his rational concept of an organisation as composed of five segments and uses his model flexibly to develop five different configurations of structure
Measuring the Differential Threshold by the Speed of the Music
LIU Yuan
Journal of Chongqing Normal University , 2009,
Abstract: This experment is based on the method of minimal change way to measure the difference threshold by the speed of the music. The materials are in the use of the two kinds of the standard music, speed of j=80 and j=120(choir Amazing Grace and Beethoven's Minuet in G, all in Midi files), by using Finale Notepad 2008 to edit and the Windows Media Player 11 to play. The compared materials are 10 pieces of the different speed but the same tune to each piece of the standard materials , descending or ascending 2 beats for Amazing Grace, while 4 beats for Minuet in G. The experiment is done by using 30 undergraduates from Beijing Normal University to judge if there is difference between the compared and standard music, each time presents 2 pieces. The result demonstrates that when j=80, the differential threshold is 2.5; while j=120, the value goes to 5, which shows a significant difference between the two speeds. It also illustrates that, the speed increases ,the difference threshold increases as well. The Fechner-Weber's law is tested to some extent but not precisely, needing a further study to juustify the theory. On the other hand ,it has something to do with our daily life, as wellas music listening, comprehension and music teaching.
Wavelet Fuzzy Neural Network based on MQPSO for Network Anomaly Detection
Yuan Liu
Journal of Networks , 2011, DOI: 10.4304/jnw.6.9.1344-1350
Abstract: Neural network (NN) employed to settle network anomaly has become prevalent. However, traditional training algorithm for NN is not optimum, that is, often suboptimum, and encountering complicated network anomaly, an adaptive yet efficient NN or hybrid NN model should be better considered. Therefore, this paper proposes a novel network anomaly detection method employing wavelet fuzzy neural network (WFNN) to use modified Quantum-Behaved Particle Swarm Optimization (QPSO). In this paper, wavelet transform is applied to extract fault characteristics from the anomaly state. Fuzzy theory and neural network are employed to fuzzify the extracted information. Wavelet is then integrated with fuzzy neural network to form the wavelet fuzzy neural network (WFNN). The Quantum-Behaved Particle Swarm Optimization, which outperforms other optimization algorithm considerably on its simple architecture and fast convergence, has previously applied to solve optimum problem. However, the QPSO also has its own shortcomings. So, there exists a modified QPSO which is used to train WFNN in this paper. Experimental result on KDD99 intrusion detection datasets shows that this WFNN using the novel training algorithm has high detection rate while maintaining a low false positive rate.
Finding binary active galactic nuclei by the centroid shift in imaging surveys
Yuan Liu
Physics , 2015, DOI: 10.1051/0004-6361/201526266
Abstract: The census of binary active galactic nuclei (AGNs) is important in order to understand the merging history of galaxies and the triggering of AGNs. However, there is still no efficient method for selecting the candidates of binary AGNs. The non-synchronous variations of the two AGNs in one binary system will induce the shift of the image centroid. Since the astrometric error is normally much smaller than the angular resolution of telescopes, it is possible to detect such shifts even in the unresolved system via multi-epoch observations. We perform some simulations and find that hundreds of observations are required to discover compact binary AGNs. This method is suitable for the future large-scale surveys, e.g., the Large Synoptic Survey Telescope, and it might lead to a large sample of binary AGNs with a 1-2 yr survey.
Gaussian integrability of distance function under the Lyapunov condition
Yuan Liu
Mathematics , 2014, DOI: 10.1214/ECP.v20-3838
Abstract: In this note we give a direct proof of the Gaussian integrability of distance function as $\mu e^{\delta d^2(x,x_0)} < \infty$ for some $\delta>0$ provided the Lyapunov condition holds for symmetric diffusion Markov operators, which answers a question proposed in Cattiaux-Guillin-Wu [6, Page 295]. The similar argument still works for diffusions processes with unbounded diffusion coefficients and for jump processes such as birth-death chains. An analogous discussion is also made under the Gozlan's condition arising from [9, Proposition 3.5].
