K-Inflation with a Dark Energy Coupling
Yubei Yue,Bin Chen
Physics , 2009, DOI: 10.1103/PhysRevD.81.023506
Abstract: It is usually thought that the quintessence as a fundamental scalar field was already present during the inflationary epoch. While there are various models in which the quintessence couples to other species, it is attractive to anticipate a coupling between the quintessence and the inflaton in the very early universe as well. We consider such a coupling in the context of k-inflation. The coupling function and the potential of the quintessence are chosen to be of power law forms. We show such a coupling affects the speed of sound for the inflaton field as well as the power spectra of perturbations.
Reionization in the Warm Dark Matter Model
Bin Yue,Xuelei Chen
Physics , 2012, DOI: 10.1088/0004-637X/747/2/127
Abstract: Compared with the cold dark matter (CDM) model, in the warm dark matter (WDM) model formation of small scale structure is suppressed. It is often thought that this would delay the reionization of the intergalactic medium (IGM), as the star formation rate during the epoch of reionization (EOR) would be lowered. However, during the later stage of the EOR, a large portion of the ionizing photons are consumed by recombination inside the minihalos, where the gas has higher density and recombination rates than the gas in the IGM. The suppression of small scale structure would therefore reduce the recombination rate, and could potentially shorten the reionization process. This effect is investigated here by using the analytical "bubble model" of reionization. We find that in some cases, though the initiation of the EOR is delayed in the WDM model, its completion could be even earlier than the CDM case, but the effect is generally small. We obtain limits on the WDM particles mass for different reionization redshifts.

Natural Science (NS) , 2012, DOI: 10.4236/ns.2012.42013
Abstract: Command protection engineering is the important component of national protection engineering system. To raise the level of its construction, a deformation prediction model is given based on Genetic Algorithm (GA), Least Square Support Vector Machines (LSSVM) and markov theory. Genetic algorithm is used to improve the parameter of LSSVM. Markov predict method is used to improve the precision of the prediction model. Finally, be used to a certain command protection engineering, the accuracy of the algorithm is improved obviously. The model is proved to be credible and precise.
An Improved Equivalent Simulation Model for CMOS Integrated Hall Plates
Yue Xu,Hong-Bin Pan
Sensors , 2011, DOI: 10.3390/s110606284
Abstract: An improved equivalent simulation model for a CMOS-integrated Hall plate is described in this paper. Compared with existing models, this model covers voltage dependent non-linear effects, geometrical effects, temperature effects and packaging stress influences, and only includes a small number of physical and technological parameters. In addition, the structure of this model is relatively simple, consisting of a passive network with eight non-linear resistances, four current-controlled voltage sources and four parasitic capacitances. The model has been written in Verilog-A hardware description language and it performed successfully in a Cadence Spectre simulator. The model’s simulation results are in good agreement with the classic experimental results reported in the literature.
A Novel Apparatus for Surveillance of Green Energy System Based on WSSs  [PDF]
Joy I. -Z. Chen, Yue Hsin Gien, Wen Bin Wu, Chieh Wen Liou
Engineering (ENG) , 2013, DOI: 10.4236/eng.2013.51A019
Abstract:

The WSSs (wireless sensor systems) concept is applied to implement an uninterrupted solar energy surveillance system in this work. The completed system is comprised of three major sub-systems that include a charging sub-system, a control sub-system and a display sub-system. Based on several transmission standards, including Bluetooth, Wifi and Zigbee capability combined with wireless transmission techniques, the proposed surveillance system is designed for monitoring a solar energy system. The performance of the simulated WSSs is evaluated using statistical report results. The proposed surveillance system can be fully extended to several different kinds of applications, such as, health care and environmental inspection. The experimental measurement results significantly show that channel fading over the propagation channel dominates the developed system performance.

A multi-phenotypic cancer model with cell plasticity
Da Zhou,Yue Wang,Bin Wu
Quantitative Biology , 2013, DOI: 10.1016/j.jtbi.2014.04.039
Abstract: The conventional cancer stem cell (CSC) theory indicates a hierarchy of CSCs and non-stem cancer cells (NSCCs), that is, CSCs can differentiate into NSCCs but not vice versa. However, an alternative paradigm of CSC theory with reversible cell plasticity among cancer cells has received much attention very recently. Here we present a generalized multi-phenotypic cancer model by integrating cell plasticity with the conventional hierarchical structure of cancer cells. We prove that under very weak assumption, the nonlinear dynamics of multi-phenotypic proportions in our model has only one stable steady state and no stable limit cycle. This result theoretically explains the phenotypic equilibrium phenomena reported in various cancer cell lines. Furthermore, according to the transient analysis of our model, it is found that cancer cell plasticity plays an essential role in maintaining the phenotypic diversity in cancer especially during the transient dynamics. Two biological examples with experimental data show that the phenotypic conversions from NCSSs to CSCs greatly contribute to the transient growth of CSCs proportion shortly after the drastic reduction of it. In particular, an interesting overshooting phenomenon of CSCs proportion arises in three-phenotypic example. Our work may pave the way for modeling and analyzing the multi-phenotypic cell population dynamics with cell plasticity.
A New Reduced-Rank Linear Discriminant Analysis Method and Its Applications
Yue Selena Niu,Ning Hao,Bin Dong
Statistics , 2015,
Abstract: Many high dimensional classification techniques have been developed recently. However, many works focus on only the binary classification problem and can not be used directly for multi-class data. Most available classification tools for the high dimensional, multi-class data are either based on diagonal covariance structure or computationally complicated. In this paper, following the idea of reduced-rank linear discriminant analysis (LDA), we introduce a new dimension reduction tool with a flavor of supervised principal component analysis (PCA). The proposed method is computationally efficient and can incorporate the correlation structure among the features. Besides the theoretical insights, we show that our method is a competitive classification tool by simulated and real data examples.
Progress of the Application of Mesoporous Silica-Supported Heteropolyacids in Heterogeneous Catalysis and Preparation of Nanostructured Metal Oxides
Yuanhang Ren,Bin Yue,Min Gu,Heyong He
Materials , 2010, DOI: 10.3390/ma3020764
Abstract: Mesoporous silica molecular sieves are a kind of unique catalyst support due to their large pore size and high surface area. Several methods have been developed to immobilize heteropolyacids (HPAs) inside the channels of these mesoporous silicas. The mesoporous silica-supported HPA materials have been widely used as recyclable catalysts in heterogeneous systems. They have shown high catalytic activities and shape selectivities in some reactions, compared to the parent HPAs in homogeneous systems. This review summarizes recent progress in the field of mesoporous silica-supported HPAs applied in the heterogeneous catalysis area and preparation of nanostructured metal oxides using HPAs as precursors and mesoporous silicas as hard templates.
