A method of analyzing the observable degree of time-varying linear systems as piece-wise constant systems(PWCS) is applied to the analysis of in-flight alignment(IFA) of inertial navigation systems(INS) whose estimability is known to be enhanced by maneuvers. It is shown that through the method based on mutual information, we can not only determine which(More)
BACKGROUND Transcatheter closure of patent ductus arteriosus (PDA) is a well established procedure and an accepted treatment modality for small to moderate-sized PDA. This study aimed to evaluate the immediate and follow-up results of transcatheter closure of large PDAs with severe pulmonary arterial hypertension (PAH) in adults. METHODS After a complete(More)
AIMS There existed an ambiguity in the current echo literature about the identification of the pulmonary veins imaged by echocardiography. This study was designed to identify the site and blood flow of individual pulmonary veins by transthoracic echocardiography. METHODS AND RESULTS Transthoracic echocardiography was used to display individual pulmonary(More)

BACKGROUND It is generally believed that three-dimensional (3D) echocardiography can provide unique en face views of atrial septal defects (ASDs), whereas conventional two-dimensional (2D) transthoracic echocardiography (TTE) cannot. The purpose of this study was to develop a special 2D TTE-based en face view of ASDs. METHODS En face views of ASDs on 2D(More)
OBJECTIVE To improve the early and late benefits (the patency and total myocardium revascularization) of coronary artery bypass grafting, stimulate us using only bilateral internal mammary artery (BIMA) composite Lima (left internal mammary artery)-Rima (right internal mammary artery) Y graft with off-pump, here is the early evaluation. METHODS From(More)
BACKGROUND Transcatheter closure of patent foramen ovale (PFO) is a promising alternative to surgical closure or anticoagulation therapy to prevent paradoxical embolic events in patients with PFO. Several different devices have been used for transcatheter PFO closure. The aim of the present study was to evaluate the safety and feasibility for closure of PFO(More)
AIM To evaluate the feasibility, safety and efficacy of the Spider™ patent foramen ovale (PFO) occluder for the treatment of PFOs in an animal model. METHOD The foramen ovale was punctured to establish an animal model of a PFO. Under fluoroscopic guidance, the PFO was occluded with the Spider PFO occluder. The piglets were electively sacrificed at months(More)
On account of the complex structure of the middle ear and that it is more difficult to carry out experiments to test the nature of the mechanical components, the relevant data is hard to obtain, which has become an obstacle restricting analysis of the middle ear mechanic. Based on spatial structure and mechanical properties of ossicular chain, the paper has(More)
