In the past few decades, many mission projects have been held regularly in China. The purpose of this audit was a retrospective analysis of a 9-year cleft lip and palate charity project operated in a tertiary hospital in China Shenzhen Area to evaluate perioperative and postoperative complications. Nevertheless, understanding the risk profile is essential for establishing a sustainable in-house cleft service in Shenzhen. Methods: A detailed analysis of hospital centralized record in the The University of Hong Kong-Shenzhen Hospital (HKUSZH) was reviewed since the first charity project held in 2015. The parameters of this audit were focused on perioperative complications including anesthesia related problems, early postoperative complications in patients who underwent primary or secondary cleft surgeries. A total of 430 consecutive admitted cases of 311 non-syndromic cleft lip & palate patients were enrolled into the charity project from June 2015 to July 2024. The main anesthesia related complications that occurred during general anesthesia were respiratory tract problems, while intraoperative complication was excessive bleeding, so as wound local infection and reaction were the main early postoperative complications. Results: In our 9-year clinical audit of 430 cleft lip and palate charity surgeries in Shenzhen, we observed no mortalities and a anesthesia-related complication rate of 1.16%. Specific intraoperative complications included excessive bleeding, while early postoperative issues were dominated by wound infections. The fistula rate of 18.7% post palate repair and the average hospital stay of 3.71 days complete the profile of our surgical outcomes. These data underscore the project’s efficacy and offer a reference for international cleft missions aiming for safe and efficient surgical care. Conclusions: This study provides a thorough data review of the complications in the past 9 years charity missions for cleft lip and palate surgery in a well-structured hospital infrastructure and logistic support by local surgical team. There were no perioperative or postoperative death during the study period and the overall short-term complication rate was low. Therefore, it could be a reference model for other international cleft mission in developing country for a safe and efficient service in future.展开更多

The review consolidates findings that show the impact of AI in improving the efficiency, accuracy and justice delivery in the legal profession. The studies show increased efficiency in speed of document review and enhancement of the accuracy of the reviewed documents, with time efficiency estimates of 60% reduction of time. However, the review also outlines some of the problems that continue to characterize AI, such as data quality problems, biased algorithms and the problem of the opaque decision-making system. This paper assesses ethical issues related to patient autonomy, justice and non-malignant suffering, with particular focus on patient privacy and fair process, and on potential unfairness to patients. This paper’s review of AI innovations finds that regulations lag behind AI developments, leading to unsettled issues regarding legal responsibility for AI and user control over AI-generated results and findings in legal proceedings. Some of the future avenues that are presented in the study are the future of XAI for legal purposes, utilizing federated learning for resolving privacy issues, and the need to foster adaptive regulation. Finally, the review advocates for Legal Subject Matter Experts to collaborate with legal informatics experts, ethicists, and policy makers to develop the best solutions to implement AI in medical negligence claims. It reasons that there is great potential for AI to have a deep impact on the practice of law but when done, it must do so in a way that respects justice and on the Rights of Individuals.展开更多

The review consolidates findings that show the impact of AI in improving the efficiency, accuracy and justice delivery in the legal profession. The studies show increased efficiency in speed of document review and enhancement of the accuracy of the reviewed documents, with time efficiency estimates of 60% reduction of time. However, the review also outlines some of the problems that continue to characterize AI, such as data quality problems, biased algorithms and the problem of the opaque decision-making system. This paper assesses ethical issues related to patient autonomy, justice and non-malignant suffering, with particular focus on patient privacy and fair process, and on potential unfairness to patients. This paper’s review of AI innovations finds that regulations lag behind AI developments, leading to unsettled issues regarding legal responsibility for AI and user control over AI-generated results and findings in legal proceedings. Some of the future avenues that are presented in the study are the future of XAI for legal purposes, utilizing federated learning for resolving privacy issues, and the need to foster adaptive regulation. Finally, the review advocates for Legal Subject Matter Experts to collaborate with legal informatics experts, ethicists, and policy makers to develop the best solutions to implement AI in medical negligence claims. It reasons that there is great potential for AI to have a deep impact on the practice of law but when done, it must do so in a way that respects justice and on the Rights of Individuals.
文摘Fabric dyeing is a critical production process in the clothing industry and heavily relies on batch processing machines(BPM).In this study,the parallel BPM scheduling problem with machine eligibility in fabric dyeing is considered,and an adaptive cooperated shuffled frog-leaping algorithm(ACSFLA)is proposed to minimize makespan and total tardiness simultaneously.ACSFLA determines the search times for each memeplex based on its quality,with more searches in high-quality memeplexes.An adaptive cooperated and diversified search mechanism is applied,dynamically adjusting search strategies for each memeplex based on their dominance relationships and quality.During the cooperated search,ACSFLA uses a segmented and dynamic targeted search approach,while in non-cooperated scenarios,the search focuses on local search around superior solutions to improve efficiency.Furthermore,ACSFLA employs adaptive population division and partial population shuffling strategies.Through these strategies,memeplexes with low evolutionary potential are selected for reconstruction in the next generation,while thosewithhighevolutionarypotential are retained to continue their evolution.Toevaluate the performance of ACSFLA,comparative experiments were conducted using ACSFLA,SFLA,ASFLA,MOABC,and NSGA-CC in 90 instances.The computational results reveal that ACSFLA outperforms the other algorithms in 78 of the 90 test cases,highlighting its advantages in solving the parallel BPM scheduling problem with machine eligibility.

文摘As a new research direction in contemporary cognitive science,predictive processing surpasses traditional computational representation and embodied cognition and has emerged as a new paradigm in cognitive science research.The predictive processing theory advocates that the brain is a hierarchical predictive model based on Bayesian inference,and its purpose is to minimize the difference between the predicted world and the actual world,so as to minimize the prediction error.Predictive processing is therefore essentially a context-dependent model representation,an adaptive representational system designed to achieve its cognitive goals through the minimization of prediction error.
