Application of Bifurcation Method to the Generalized Zakharov Equations
Ming Song
Abstract and Applied Analysis , 2012, DOI: 10.1155/2012/308326
Abstract: We use the bifurcation method of dynamical systems to study the traveling wave solutions for the generalized Zakharov equations. A number of traveling wave solutions are obtained. Those solutions contain explicit periodic blow-up wave solutions and solitary wave solutions.
A High Power Carbon/LiMxOy Hybrid Cathode for Non-Aqueous Li-O2 Battery  [PDF]
Ming Song, Jing Peng, Xiang Yu
Advances in Materials Physics and Chemistry (AMPC) , 2017, DOI: 10.4236/ampc.2017.710029
Abstract: Among all the issues that restrict the application of Li-air battery, poor power performances of O2 cathode comes first. In this paper, we establish carbon (Super P)/LiMxOy (LiMn2O4/LiFePO4/LiNi1/3Co1/3Mn1/3O2) hybrid cathode to promote the power output of conventional carbon cathode through continuous Li+-insertion reaction of LiMxOy and Li+ transportation in bulk LiMxOy during the discharging process. Weight and volume specific power performances of the hybrid cathode are much higher than those of traditional Super P carbon cathode. The mechanism of improving power performance of O2 cathode has also been discussed through electrochemical impedance spectroscopy and cyclic voltammetry method in this paper.
Traveling Wave Solutions for the Generalized Zakharov Equations

Ant-Based Transmission Range Assignment Scheme for Energy Hole Problem in Wireless Sensor Networks
Ming Liu,Chao Song
International Journal of Distributed Sensor Networks , 2012, DOI: 10.1155/2012/290717
Abstract: We investigate the problem of uneven energy consumption in large-scale many-to-one sensor networks (modeled as concentric coronas) with constant data reporting, which is known as an energy hole around the sink. We conclude that lifetime maximization and the energy hole problem can be solved by searching optimal transmission range for the sensors in each corona and then prove this is an NP-hard optimization problem. In view of the effectiveness of ant colony algorithms in solving combinatorial optimization problems, we propose an ant-based heuristic algorithm (ASTRL) to address the optimal transmission range assignment for the goal of achieving life maximization of sensor networks. Experimentation shows that the performance of ASTRL is very close to the optimal results obtained from exhaustive search method. Furthermore, extensive simulations have also been performed to evaluate the performance of ASTRL using various simulation parameters. The simulation results reveal that, with low communication cost, ASTRL can significantly mitigate the energy hole problem in wireless sensor networks with either uniform or nonuniform node distribution. 1. Introduction Rapid technological advances in microelectromechanical systems (MEMS) and low-power wireless communications have enabled the deployment of large scale wireless sensor networks (WSNs). The potential applications of sensor networks are highly varied, such as environmental monitoring, target tracking, and battlefield surveillance [1, 2]. Due to limited and nonrechargeable energy provision, the energy resource of sensor networks should be managed wisely to extend the lifetime of sensors [3–7]. The sink node in a WSN receives the data from the sensor nodes and forwards these data to the applications over the WSN. Usually, the sensor nodes closest to the sink tend to deplete their energy budget more rapidly than others [8–10] because such nodes need to transmit more data than other nodes. This causes the problem of energy hole around the sink. A WSN suffering from the energy hole problem cannot deliver more data, and consequently the network lifetime has been greatly shortened, although most of the sensor nodes can still work properly. Recently, there have been a number of studies done on the energy hole problem for improving the network lifetime. Generally, these studies aiming to mitigate or solve the energy hole problem can be divided into 3 categories: (i) assistant approaches, such as deployment assistance, traffic compression, and aggregation in [11]; (ii) node distribution strategies.

Search for Higgs, Leptoquarks, and Exotics at Tevatron
Song Ming Wang
Physics , 2004,
Abstract: This paper reviews some of the most recent results from the CDF and DZERO experiments on the searches for Standard Model and Non-Standard Model Higgs bosons, and other new phenomena at the Tevatron. Both experiments examine data from proton anti-proton collision at sqrt{s} = 1.96 TeV, of integrated luminosity ~200$ pb**-1 (per experiment), to search for Higgs predicted in the Standard Model and beyond Standard Model, supersymmetric particles in the Gauge Mediated Symmetry Breaking scenario, leptoquarks, and excited electrons. No signal was observed, and limits on the signatures and models are derived.
