Background Pulmonary artery stenosis is often associated with congenital heart disease. The aim of the study was to evaluate efficacy and safety stenting for branch pulmonary using a biodegradable nitride iron stent (IBS ® Angel™) right ventricular systolic diastolic function. Methods From July 2021 February 2022, total 11 cases (ages ranged from 36 86 months old) were included in this pre post-intervention, prospective, cohort preclinical study. All underwent transthoracic echocardiographic...

Early surgical closure is warranted to prevent aortic valve lesion and regurgitation (AR) in intracristal ventricular septal defects (icVSDs). Experiences for transcatheter device of icVSDs are still limited. Our objectives investigate AR progression following children explore the risk factors progression.From January 2007 December 2017, 50 with icVSD who had successfully undergone were enrolled. With 4.0 (interquartile range: 3.0-6.2) years follow-up, was observed 20% (10/50) patients after...

In this paper, we investigate disaster-recovery communications utilizing simultaneous wireless information and power transfer (SWIPT) enabled decode-and-forward (DF) relay D2D network. Specifically, there is a disaster area between the source node target node, cannot be installed in area. So optimal location for must found healthy Moreover, unlike existing with assumption of linear or piece-wise energy harvesting (EH) model, realistic scenario nonlinear EH model has been taken into account....

Objectives. To observe and analyze the long-term change of different types arrhythmias after transcatheter closure perimembranous ventricular septal defect (pmVSD). Methods. We retrospectively collected data patients who underwent pmVSD in our institution from March 2002 to December 2010. Results. One hundred thirty-nine met inclusion criteria, which 265 (25.5%) had early arrhythmia. They were classified into two categories: conduction abnormality (191/1039; 18.4%) origin (94/1039; 9.0%),...

Language models pre-trained on general text have achieved impressive results in diverse fields. Yet, the distinct linguistic characteristics of task-oriented dialogues (TOD) compared to limit practical utility existing language models. Current dialogue pre-training methods overlook one-to-many property conversations, where multiple responses can be appropriate given same conversation context. In this paper, we propose a novel model called DivTOD, which collaborates with LLMs learn...
