Distribution of Action Potential Duration and T-wave Morphology: a Simulation Study (2009)
Ryzhii, Elena, Ryzhii, Maxim, Wei, Daming
The results of a simulation study of the action potential duration (APD) distribution and T-wave morphology taking into account the midmyocardial cells (M-cells) concept are described. To investigate...
Improving the Parallelism of Iterative Methods by Aggressive Loop Fusion (2009)
Jingling Xue, Minyi Guo, Daming Wei
Abstract. Traditionally, loop nests are fused only when the data dependences in the loop nests are not violated. This paper presents a new loop fusion algorithm that is capable of fusing loop nests...
The initial Lorentz factors of fireballs inferred from the early X-ray data of SWIFT GRBs (2009)
Xue, Rongrong, Fan, Yizhong, Wei, Daming
We intend to determine the type of circumburst medium and measure directly the initial Lorentz factor $\Gamma_0$ of GRB outflows. If the early X-ray afterglow lightcurve has a peak and the whole...
GeV Emission from neutron-rich internal shocks of some long Gamma-ray Bursts (2008)
Xue, Rongrong, Fan, Yizhong, Wei, Daming
In the neutron-rich internal shocks model for gamma-ray bursts (GRBs), the Lorentz factors (LFs) of ion shells are variable, and so are the LFs of accompanying neutron shells. For slow neutron shells...
A Near Real-Time Approach for Convolutive Blind Source Separation (2008)
Shuxue Ding, Jie Huang, Daming Wei, Andrzej Cichocki
Abstract—In this paper, we propose an algorithm for real-time signal processing of convolutive blind source separation (CBSS), which is a promising technique for acoustic source separation in a...
ADivide-and-Conquer Algorithm for Irregular Redistribution in Parallelizing Compilers (2008)
Hui Wang, Minyi Guo, Daming Wei
Abstract. In order to achieve higher load balancing, it is necessary to solve irregular block redistribution problems, which are different from regular block-cyclic redistribution. High Performance...
Li, Yuan, Li, Aigen, Wei, Daming
The dust extinction of gamma-ray bursts (GRBs) host galaxies, containing important clues to the nature of GRB progenitors and crucial for dereddening, is still poorly known. Here we propose a...
Dust Extinction of Gamma-ray Burst Host Galaxies: Identification of Two Classes? (2006)
Chen, Shilun, Li, Aigen, Wei, Daming
Dust in the host galaxies of gamma-ray bursts (GRBs) dims and reddens their afterglow spectra. Knowledge of the nature of this dust is crucial for correcting for extinction, providing clues to the...
Message Scheduling for Irregular Data Redistribution in Parallelizing Compilers (2006)
WANG, Hui, GUO, Minyi, WEI, Daming
In parallelizing compilers on distributed memory systems, distributions of irregular sized array blocks are provided for load balancing and irregular problems. The irregular data redistribution is...
This paper proposes a lead method and a processing means for monitoring the 12-lead electrocardiogram (ECG) with four standard leads. Leads I,II of the M-L leads and leads V1, V6 of the chest leads...
Shape Deblurring with Unsharp Masking Applied to Mesh Normals (2002)
Yagou,Hirokazu, Belyaev,Alexander, Wei,Daming
Unsharp masking is a well-known image sharpening technique. Given an image and its smoothed version, amplifying high frequencies of the image via unsharp masking is achieved by linear extrapolation...
Mesh Median Filter for Smoothing 3-D Polygonal Surfaces (2002)
