Performance engineering of service compositions

John C. Grundy, John G. Hosking, Lei Li, Na Liu
SOSE '06
2006

While a service-oriented approach to software engineering has become popular in recent times, the actual performance of systems composed from many distributed parts is still largely unpredictable. We… (More)

A Well-Balanced Symplecticity-Preserving Gas-Kinetic Scheme for Hydrodynamic Equations under Gravitational Field

Jun Luo, Kun Xu, Na Liu
SIAM J. Scientific Computing
2011

A well-balanced scheme for an isolated gravitational hydrodynamic system is defined as a scheme which exactly preserves an isothermal hydrostatic solution. In this paper, a well-balanced gas-kinetic… (More)

A label-free immunosensor based on graphene nanocomposites for simultaneous multiplexed electrochemical determination of tumor markers.

Xinle Jia, Zhimin Liu, Na Liu, Zhanfang Ma
Biosensors & bioelectronics
2014

Here we prepared a label-free electrochemical immunosensor employing indium tin oxide (ITO) sheets as working electrodes and graphene nanocomposites as supporting matrix for simultaneous… (More)

Optimal Pricing, Modularity, and Return Policy Under Mass Customization

Na Liu, Tsan-Ming Choi, Chun-Wah Marcus Yuen, Frankie Ng
IEEE Transactions on Systems, Man, and…
2012

Mass customization (MC) is a pertinent industrial practice. Different from the non-MC products, consumer return for MC products is typically prohibited. MC retailers can thus gain significant… (More)

A social identity perspective on participation in virtual healthcare communities

Virtual healthcare communities are incorporating social network features to motivate more participation. Using the lens of social identity theory, this study looks at how the social network structure… (More)

Platinum porous nanoparticles hybrid with metal ions as probes for simultaneous detection of multiplex cancer biomarkers.

Zifeng Wang, Na Liu, Zhanfang Ma
Biosensors & bioelectronics
2014

In this work, platinum porous nanoparticles (PtPNPs) absorbed metal ions as electrochemical signals were fabricated. Clean-surface PtPNPs were prepared by a surfactant-free method and decorated with… (More)

Mixed Finite Element Method for 2 D Vector Maxwell ’ s Eigenvalue Problem in Anisotropic Media

Wei Jiang, Na Liu, Yifa Tang, Qing Huo Liu
2014

It is well known that the conventional edge element method in solving vector Maxwell’s eigenvalue problem will lead to the presence of nonphysical zero eigenvalues. This paper uses the mixed finite… (More)

Nanoantenna-enhanced gas sensing in a single tailored nanofocus

Na Liu, Ming Lee Tang, Mario Hentschel, Harald Giessen, A Paul Alivisatos
CLEO: - Laser Science to Photonic Applications
2011

We demonstrate antenna-enhanced hydrogen sensing at the single-particle level. We place a single palladium nanoparticle near the tip region of a gold nanoantenna and detect the changing optical… (More)

Three-dimensional plasmon rulers.

Na Liu, Mario Hentschel, Thomas Weiss, A Paul Alivisatos, Harald Giessen
Science
2011

Plasmon rulers can be used to determine nanoscale distances within chemical or biological species. They are based on the spectral shift of the scattering spectrum when two plasmonic nanoparticles… (More)

Coupling effects in optical metamaterials.

Na Liu, Harald Giessen
Angewandte Chemie
2010

Metamaterials have become one of the hottest fields of photonics since the pioneering work of John Pendry on negative refractive index, invisibility cloaking, and perfect lensing. Three-dimensional… (More)
