Simultaneous Interpreting: Principles and Training
Zhongmei Chen,Xiaobo Dong
Journal of Language Teaching and Research , 2010, DOI: 10.4304/jltr.1.5.714-716
Abstract: Nowadays, there is an increasing demand for simultaneous interpreting in China. This paper introduces the definition and the process of simultaneous interpreting. And then, it proposes the general principles and techniques for simultaneous interpreting, and provides practical self-training methods.

Invariance in the Seasonal Median Dates for Mono-Modal Monsoonal Rainfall Distribution over the Semi-Arid Ecotone of Sub-Saharan West Africa  [PDF]
Naraine Persaud, Moustafa Elrashidi, Xiaobo Zhou, Xining Zhao, Xiaoli Chen
International Journal of Geosciences (IJG) , 2013, DOI: 10.4236/ijg.2013.46A2001
Abstract:

Seasonal distribution of mono-modal, monsoonal rainfall across the semi-arid ecotone of sub-Saharan of West Africa is highly variable and unpredictable. The ever-present risk of drought and crop failure in this environment often results in food shortages that are met by emergency food aid. Humanitarian assistance planners would be better prepared for such interventions in a timely manner if they have reliable indicators that forewarn the impending failure of the rains. A good indicator would be a characteristic of the seasonal rainfall distribution that can be shown to be reasonably invariant over time and space. The objective of this study is to investigate whether such invariance existed for the seasonal median date (meaning the date when 50% of the seasonal total occurs). Such invariance is expected since the sun’s cyclic declination forces the advance and retreat of the Inter-tropical Front over West Africa. We examined the statistical properties of the seasonal median date for 1349 station-years of rainfall records for 30 rainfall stations in Burkina Faso and Niger with coordinates ranging from 9.88° to 18.5° north latitude and -4.77° to 13.2° longitude. The results showed that the median date was quite narrowly distributed over years with rather weak dependence on geographical coordinates. It can therefore be used as a reasonable ex-ante indicator of the success or failure of the rains as the rainy season progress.

Risk of Cardiovascular Disease Associated with the Exposure of Particulate Matter (PM2.5): Review  [PDF]
Rabina Sinkemani, Arjun Sinkemani, Xiaobo Li, Rui Chen
Journal of Environmental Protection (JEP) , 2018, DOI: 10.4236/jep.2018.96038
Abstract: Association of particulate matter (PM2.5) increases the risk of cardiovascular disease. Experimental and clinical evidences suggested that PM2.5 is directly linked with cardiovascular disease. PM2.5 also plays an important role in the biological mechanisms influencing in the cardiovascular system. Here in this review, we tried to discuss that PM2.5 is associated with the increase risk of cardiovascular disease in which PM2.5 air pollutants enter through the alveolar of the lungs through the systemic circulation inducing cardiovascular disease. More studies need to be done for further understanding to clarify the interactions of PM2.5 components associated with cardiovascular disease.

An Approach to Improving Bug Assignment with Bug Tossing Graphs and Bug Similarities
Liguo Chen,Xiaobo Wang,Chao Liu
Journal of Software , 2011, DOI: 10.4304/jsw.6.3.421-427
Abstract: In open-source software development a new bug firstly is found by developers or users. Then the bug is described as a bug report, which is submitted to a bug repository. Finally the bug triager checks the bug report and typically assigns a developer to fix the bug. The assignment process is time-consuming and error-prone. Furthermore, a large number of bug reports are tossed (reassigned) to other developers, which increases bug-fix time. In order to quickly identify the fixer to bug reports we present an approach based on the bug tossing history and textual similarities between bug reports. This proposed approach is evaluated on Eclipse and Mozilla. The results show that our approach can significantly improve the efficiency of bug assignment: the bug fixer is often identified with fewer tossing events.
Galilean invariance of lattice Boltzmann models
Xiaobo Nie,Xiaowen Shan,Chen Hudong
Physics , 2008, DOI: 10.1209/0295-5075/81/34005
Abstract: It is well-known that the original lattice Boltzmann (LB) equation deviates from the Navier-Stokes equations due to an unphysical velocity dependent viscosity. This unphysical dependency violates the Galilean invariance and limits the validation domain of the LB method to near incompressible flows. As previously shown, recovery of correct transport phenomena in kinetic equations depends on the higher hydrodynamic moments. In this Letter, we give specific criteria for recovery of various transport coefficients. The Galilean invariance of a general class of LB models is demonstrated via numerical experiments.
Resolving singular forces in cavity flow: Multiscale modeling from atoms to millimeters
Xiaobo Nie,Mark. O. Robbins,Shiyi Chen
Physics , 2005, DOI: 10.1103/PhysRevLett.96.134501
Abstract: A multiscale approach for fluid flow is developed that retains an atomistic description in key regions. The method is applied to a classic problem where all scales contribute: The force on a moving wall bounding a fluid-filled cavity. Continuum equations predict an infinite force due to stress singularities. Following the stress over more than six decades in length in systems with characteristic scales of millimeters and milliseconds allows us to resolve the singularities and determine the force for the first time. The speedup over pure atomistic calculations is more than fourteen orders of magnitude. We find a universal dependence on the macroscopic Reynolds number, and large atomistic effects that depend on wall velocity and interactions.
Lattice-Boltzmann Simulations of Fluid Flows in MEMS
Xiaobo Nie,Gary D. Doolen,Shiyi Chen
Physics , 1998,
Abstract: The lattice Boltzmann model is a simplified kinetic method based on the particle distribution function. We use this method to simulate problems in MEMS, in which the velocity slip near the wall plays an important role. It is demonstrated that the lattice Boltzmann method can capture the fundamental behavior in micro-channel flow, including velocity slip and nonlinear pressure drop along the channel. The Knudsen number dependence of the position of the vortex center and the pressure contour in micro-cavity flows is also demonstrated.
