First detection of CO lines in a water fountain star (2008)

He, J. H., Imai, H., Hasegawa, T. I., Campbell, S. W., Nakashima, J.

[Context] Water fountain stars are very young post-AGB stars with high velocity water maser jets. They are the best objects to study the onset of bipolar jets from evolved stars due to their young...

A spectral line survey in the 2 mm and 1.3 mm windows toward the carbon rich envelope of IRC +10216 (2008)

He, J. H., Kwok, S., Mueller, H. S. P., Zhang, Y., Hasegawa, T., ...

We present the results of our spectral line surveys in the 2 mm and 1.3 mm windows toward the carbon rich envelope of IRC +10216. Totally 377 lines are detected, among which 360 lines are assigned to...

Envelope density pattern around wide binary AGB stars: a dynamical model (2007)

He, J. H.

The goal is to build up a simple dynamical model for the out-flowing circumstellar envelope around AGB stars in a wide binary system to explore the parameter dependence of the geometrical...

Three-dimensional effect on the effective thermal conductivity of porous media (2007)

Wang, Moran R, Wang, J K, Pan, N, Chen, S Y, He, J H

A three- dimensional mesoscopic method is developed for predicting the effective thermal conductivity of multiphase random porous media. The energy transport equations are solved by a lattice...

An energy-efficient adaptive DSC scheme for wireless sensor networks (2007)

Tang, Z. Y., Glover, I. A., Evans, A. N., He, J. H.

Distributed source coding (DSC) has been proven in theory that it can be used to compress correlated signals with or without loss. Recently this coding method has been used for the application of...

Modelling and fabrication of low operation temperature microcages with a polymer/metal/DLC trilayer structure (2006)

Luo, J.K., Huang, R., He, J.H., Fu, Y.Q., Flewitt, A.J., Spearing, S.M., ...

Multi-finger microcages with metal/diamond like carbon (DLC) bilayer and polymer/metal/DLC trilayer structures were analyzed, simulated and fabricated. Modelling by finite element analysis showed...

On the difference between type E and A OH/IR stars (2005)

He, J. H., Chen, P. S.

The observed SEDs of a sample of 60 OH/IR stars are fitted using a radiative transfer model of a dusty envelope. Among the whole sample, 21 stars have reliable phase-lag distances while the others...

The OH 1612 MHz maser pump rates of stellar, interstellar and post-AGB OH masers (2005)

He, J. H.

(Pseudo) radiative pumprate of OH 1612 MHz masers is defined for a sample of 44 OH/IR sources (infrared sources with OH 1612 MHz maser), irrespective of the real maser pumping mechanisms. The...

Synthesis of Si-Ge Oxide Nanowires via the Transformation of of Si-Ge Thin Films with Self-Assembled Au Catalysts (2005)

He, J. H., Wu, T. H., Hsin, C. L., Chen, L. J., Wang, Z. L.

A technique has been developed to transform a Si-Ge thin film into Si-Ge oxide nanowires with the assistance of Au particles through a three-step annealing process. A honeycomb network of Au...

Fabrication and characterization of diamond-like carbon/Ni bimorph normally closed microcages (2005)

Luo, J.K., He, J.H., Fu, Y.Q., Flewitt, A.J., Spearing, S.M., Fleck, N.A., ...

Normally closed microcages based on highly compressively stressed diamond-like carbon (DLC) and electroplated Ni bimorph structures have been simulated, fabricated and characterized. Finite-element...

He, J. H., Wu, T. H., Hsin, C. L., Chen, L. J., Wang, Z. L. (Zhong Lin)

A technique has been developed to transform a Si-Ge thin film into Si-Ge oxide nanowires with the assistance of Au particles through a three-step annealing process. A honeycomb network of Au...

Search for radiative pumping lines of OH masers: I. The 34.6um absorption line towards 1612 MHz OH maser sources (2004)

He, J. H., Szczerba, R., Chen, P. S., Sobolev, A. M.

The 1612 MHz hydroxyl maser in circumstellar envelopes has long been thought to be pumped by 34.6um photons. Only recently, the Infrared Space Observatory has made possible spectroscopic observations...

Searching for radiative pumping lines of OH masers: II. The 53.3um absorption line towards 1612MHz OH maser sources (2004)

He, J. H., Chen, P. S.

This paper analyzes the 53.3um line in the ISO LWS spectra towards a similar sample of OH/IR sources. We find 137 LWS spectra covering 53.3um and associated with 47 galactic OH/IR sources. Ten of...

Radiative pumping of 1612 MHz OH masers: OH/IR sources with IRAS LRS spectra and 34.6 micrometer absorption feature (2002)

Szczerba, R., He, J. H., Chen, P. S.

The population inversion which leads to the 1612 MHz OH maser emission has long been thought to be radiatively pumped. Since OH rotational lines involved in this pumping scheme lie in the...
