Abstract The increasing occurrence of corrosion-related damage in steel pipelines has led to the growing use of composite-based repair techniques as an efficient alternative to traditional replacement methods. Computer modeling and structural analysis were performed for the repair reinforcement of a steel pipeline with a composite bandage. A preliminary analysis of possible contact interaction schemes was implemented based on the theory of cylindrical shells, taking into account transverse shear deformations. The finite element method was used for a detailed study of the stress state of the composite bandage and the reinforced section of the pipeline. The… More >

Abstract Planning in lexical-prior-free environments presents a fundamental challenge for evaluating whether large language models (LLMs) possess genuine structural reasoning capabilities beyond lexical memorization. When predicates and action names are replaced with semantically irrelevant random symbols while preserving logical structures, existing direct generation approaches exhibit severe performance degradation. This paper proposes a symbol-agnostic closed-loop planning pipeline that enables models to construct executable plans through systematic validation and iterative refinement. The system implements a complete generate-verify-repair cycle through six core processing components: semantic comprehension extracts structural constraints, language planner generates text plans, symbol translator performs structure-preserving mapping,… More >

Abstract Automated Program Repair (APR) techniques have shown significant potential in mitigating the cost and complexity associated with debugging by automatically generating corrective patches for software defects. Despite considerable progress in APR methodologies, existing approaches frequently lack contextual awareness of runtime behaviors and structural intricacies inherent in buggy source code. In this paper, we propose a novel APR approach that integrates attention mechanisms within an autoencoder-based framework, explicitly utilizing structural code affinity and execution context correlation derived from stack trace analysis. Our approach begins with an innovative preprocessing pipeline, where code segments and stack traces are… More >

Abstract In erasure-coded storage systems, updating data requires parity maintenance, which often leads to significant I/O amplification due to “write-after-read” operations. Furthermore, scattered parity placement increases disk seek overhead during repair, resulting in degraded system performance. To address these challenges, this paper proposes a Cognitive Update and Repair Method (CURM) that leverages machine learning to classify files into write-only, read-only, and read-write categories, enabling tailored update and repair strategies. For write-only and read-write files, CURM employs a data-difference mechanism combined with fine-grained I/O scheduling to minimize redundant read operations and mitigate I/O amplification. For read-write files,… More >

Abstract Background: We evaluated surgical outcomes of biventricular repair for atrioventricular septal defect (AVSD) with tetralogy of Fallot (TOF) or double-outlet right ventricle (DORV). Methods: This retrospective pilot study included 12 patients who underwent biventricular repair of AVSD with TOF (n = 6) or DORV (n = 6) between 2004 and 2023. Right ventricular outflow tract (RVOT) reconstruction was performed using transannular patch (TAP, n = 4) or pulmonary valve preservation (PVP, n = 8). Clinical outcomes, including longitudinal pulmonary valve growth, RVOT obstruction, and pulmonary regurgitation, were reviewed descriptively, with particular focus on the feasibility of PVP.… More >

Abstract Background: During the surgical repair of complex congenital heart disease (CCHD), a subset of patients is unable to tolerate abrupt postoperative hemodynamic shifts, which can lead to significant complications. To mitigate this risk, certain abnormal venous channels are deliberately left open at the conclusion of surgery to provide a decompressive route, thereby reducing the likelihood of pulmonary hypertensive crises. Nevertheless, the continued patency of these vessels may induce chronic hemodynamic disturbances, often requiring subsequent treatment. This study was designed to assess the safety and efficacy of transcatheter intervention for such persistent anomalous systemic veins in CCHD… More >

Abstract 1 Introduction
Joint and cardiovascular diseases, such as osteoarthritis (OA) and myocardial infarction (MI), pose significant clinical challenges due to their limited regenerative capacity. The key to mitigating tissue damage and preventing the progression of OA and MI is to repair or even regenerate the infarcted tissue. At present, cell-based therapy is the primary strategy for tissue repair. Delivered cells could either differentiate into functional cells or secrete paracrine signals to promote onsite cell function. Both mechanisms have demonstrated potential in cartilage and cardiac tissue repair, both preclinically and clinically. In addition to cell therapy,… More >

Abstract Objective: The aim of the present study was to investigate long-term efficacy and safety of percutaneous stent implantation for residual pulmonary artery stenosis (PAS) in pediatric patients after surgical repair of complicated congenital heart diseases (CHDs). Methods: All pediatric patients diagnosed with residual PAS after surgical repair of complicated CHDs between 1996 and 2020 were retrospectively enrolled in the study. Results: A total of 41 patients (30 males, 11 females; median age 5.0 years, median weight 17 kg) were followed-up for a median of 7.1 years. Follow-up echocardiography results demonstrated that the target vessel diameter increased from… More >

Abstract Residual atrioventricular valve regurgitation after correction of complete atrioventricular septal defect (cAVSD) is still not ideal. As a modification of the double-patch method, our technique comprises a suture-bite-wide strip of a third patch that is incorporated to the upper margin of the left side of the ventricular septal defect (VSD) patch. This third patch counteracts not only the valvular tissue loss caused by the suture bites but also the rightward displacement of the VSD patch in a bulged fashion that occurs with increased left ventricular pressure after weaning from cardiopulmonary bypass. This unfavorable outcome was More >
