In this letter, a new decomposition algorithm of type-IV discrete cosine transform/type-IV discrete sine transform (DCT-IV/DST-IV) and architecture of a hardware accelerator for realizing fast inverse modified discrete cosine transform (IMDCT) computation are presented. The comparisons of computational complexity with some well-known algorithms show that(More)
Of 18,365 patients who underwent coronary angiography with a 4F or 5F universal catheter between April 2004 and May 2007, 24 (0.131%) experienced sustained ventricular tachycardia or ventricular fibrillation during the procedure. There was no significant difference in any clinical or angiographic characteristic between patients who had a ventricular(More)
To simulate pulse wave propagation, we set up a wave propagation model using blood-wall interaction in previous work. In this paper, our purpose is to investigate wall stress and deformation of the wave propagation model. The finite element method is employed for solving the governing equations of blood and wall. Our results suggest that there are two peaks(More)
OBJECTIVE The clinical features of patients with mediastinal and/or neck hematoma after transradial cardiac catheterization were reviewed and analyzed to help the clinicians to recognize this complication, and try their best to avoid the complication and treat the complication properly. METHODS A total of 8 patients with mediastinal and/or neck hematoma(More)
BACKGROUND In recent years, most drug-eluting stents (DESs) were domestically produced in China, but how domestic DESs perform compared to imported DESs was still unknown. METHODS A total of 9011 consecutive cases with DESs implantation in a single center throughout 2013 were prospectively collected. Two-year clinical outcomes were evaluated between(More)
