Cosmological Implications of 5-dimensional Brans-Dicke Theory (2009)

Qiang, Li-e, Gong, Yan, Ma, Yongge, Chen, Xuelei

The five dimensional Brans-Dicke theory naturally provides two scalar fields by the Killing reduction mechanism. These two scalar fields could account for the accelerated expansion of the universe....

Cosmology with Photometric Surveys of Type Ia Supernovae (2009)

Gong, Yan, Cooray, Asantha, Chen, Xuelei

We discuss the extent to which photometric measurements alone can be used to identify Type Ia supernovae (SNIa) and to determine redshift and other parameters of interest for cosmological studies. We...

Primordial Non-Gaussianity from LAMOST Surveys (2009)

Gong, Yan, Wang, Xin, Zheng, Zheng, Chen, Xuelei

The primordial non-Gaussianity (PNG) in matter density perturbation is a very powerful probe of the physics of the very early Universe. The local PNG can induce a distinct scale-dependent bias on the...

Couplings between holographic dark energy and dark matter (2009)

Ma, Yinzhe, Gong, Yan, Chen, Xuelei

We consider the interaction between dark matter and dark energy in the framework of holographic dark energy, and propose a natural and physically plausible form of interaction, in which the...

Dark energy and neutrino mass constraints from weak lensing, supernova, and relative galaxy ages (2008)

Gong, Yan, Zhang, Tong-Jie, Lan, Tian, Chen, Xue-Lei

We use the current weak lensing data to constrain the equation of state of dark energy $w$ and the total mass of massive neutrinos $\sum m_{\nu}$. The constraint on $w$ would be weak if only the...

Proc 13th Intl Conference on Virtual Systems and Multimedia Augmented Virtuality Space: Enriching Virtual Design Environments with Reality (2008)

Xiangyu Wang, Yan Gong

Abstract. As compared with Virtual and Augmented Reality, Augmented Virtuality (AV) has rarely been explored for design applications. Augmented Virtuality refers to a predominantly virtual...

Cosmological constraints on unparticle dark matter (2008)

Gong, Yan, Chen, Xuelei

In unparticle dark matter (unmatter) models the equation of state of the unmatter is given by $p=\rho/(2d_U+1)$, where $d_U$ is the scaling factor. Unmatter with such equations of state would have a...

Cosmological Constraints on Invisible Decay of Dark Matter (2008)

Gong, Yan, Chen, Xuelei

The cold dark matter may be in a meta-stable state and decays to other particles with a very long lifetime. If the decaying products of the dark matter are weakly interacting, e.g. neutrinos, then it...

Features of holographic dark energy under the combined cosmological constraints (2007)

Ma, Yin-Zhe, Gong, Yan, Chen, Xuelei

We investigate the observational signatures of the holographic dark energy models in this paper, including both the original model and a model with an interaction term between the dark energy and...

Two Component Model of Dark Energy (2007)

Gong, Yan, Chen, Xuelei

We consider the possibility that the dark energy is made up of two or more independent components, each having a different equation of state. We fit the model with supernova and gamma-ray burst (GRB)...

Immersed-Interface Finite-Element Methods for Elliptic and Elasticity Interface Problems (2007)

Gong, Yan

The purpose of the research has been to develop a class of new finite-element methods, called immersed-interface finite-element methods, to solve elliptic and elasticity interface problems with...

Perceptions of augmented reality in the design sector (2007)

Wang, Xiangyu, Gu, Ning, Marchant, David, Gong, Yan, Kim, Mi Jeong

Nowadays the architectural design industry takes account of collaboration among design team members as seriously as geometric and spatial features of the design itself. Effective collaboration should...

CAPABILITIES AND ROUTINES IN NEW ORGANIZATIONS: (2006)

Yan Gong, Ted Baker, Anne S. Miner, Of Management, Human Resources

Emerging organizational research has proposed increasingly nuanced links between capabilities and routines, which in turn play vital roles in organizational survival and prosperity. We draw on prior...

Gong, Yan

RESUMEN RESUMEN   In this work, a class of new finite-element methods, called immersed-interface finite-element methods, is developed to solve elliptic interface problems with...

Sequential Inactivation of rdxA (HP0954) and frxA (HP0642) Nitroreductase Genes Causes Moderate and High-Level Metronidazole Resistance in Helicobacter pylori

Jeong, Jin-Yong, Mukhopadhyay, Asish K., Dailidiene, Daiva, Wang, Yipeng, Velapatiño, Billie, Gilman, Robert H., ...

Helicobacter pylori is a human-pathogenic bacterial species that is subdivided geographically, with different genotypes predominating in different parts of the world. Here we test and extend an...

Evidence for Serine/Threonine and Histidine Kinase Activity in the Tobacco Ethylene Receptor Protein NTHK21

Zhang, Zhi-Gang, Zhou, Hua-Lin, Chen, Tao, Gong, Yan, Cao, Wan-Hong, Wang, Yu-Jun, ...

Ethylene plays important roles in plant growth, development, and stress responses. Two ethylene receptors, ETR1 from Arabidopsis and NTHK1 from tobacco (Nicotiana tabacum), have been found to have...
