BACKGROUND Transplant teams often hesitate to use the right kidney(RK)in living donor(LD)transplants due to the complexities of anastomosing the short,thin-walled right renal veins,which can potentially lead to graft loss or graft dysfunction.Nevertheless,circumstances may arise where selecting the RK over the left kidney(LK)is unavoidable.Consequently,it is crucial to thoroughly examine the implications of such a choice on the overall transplant outcome.AIM To compare transplant outcomes between recipients of RK and LK while examining the factors that influence these outcomes.METHODS We retrospectively analyzed data from adult patients who received LD kidney transplants involving meticulous patient selection and surgical techniques at our center from January 2020 to December 2023.We included all kidney donors who were over 18,fit to donate,and had undergone diethylenetriamine pentaacetic acid split function and/or computed tomography based volumetry.The variables examined comprised donor and recipient demographics,and outcome measures included technical graft loss(TGL),delayed or slow graft function(SGF),and post-transplant serum creatinine(SC)trends.We used a logistic regression model to assess the likelihood of adverse outcomes considering the donor kidney side.RESULTS Of the 250 transplants performed during the period,56(22%)were RKs.The recipient demographics and transplant factors were comparable for the right and LKs,except that the donor warm and cold ischemia time were shorter for RKs.TGL and SGF each occurred in 2%(n=1)of RKs and 0.5%(n=1)of LKs,the difference being insignificant.These complications,however,were not related to the venous anastomosis.One RK(2%)developed delayed graft function after 48 hours,which was attributable to postoperative hypoxia rather than the surgical technique.The post-transplant SC trend and mean SC at the last follow-up were similar across both kidney sides.CONCLUSION The donor kidney side has little impact on post-transplant adverse events and graft function in LD transplants,provided that careful patient selection and precise surgical techniques are employed. 展开更多

In the ISO,we have three pillars.The first pillar is the ISO members.Now we have 174 members,one representing one country.I would like to recognize that China plays a very important role in the governance of ISO,as China is a permanent member of the ISO Council and the Board of Directors,and also a permanent member of the Technical Management Board.The second pillar is our technical activities.We don’t write our standards,and the standards are written by technical experts appointed by the ISO members.Now we have around 800 technical committees and subcommittees,and an incredible portfolio of over 25,000 international standards.And 75%of the ISO members are developing countries. 展开更多

This study provides a systematic investigation into the influence of feature selection methods on cryptocurrency price forecasting models employing technical indicators.In this work,over 130 technical indicators—covering momentum,volatility,volume,and trend-related technical indicators—are subjected to three distinct feature selection approaches.Specifically,mutual information(MI),recursive feature elimination(RFE),and random forest importance(RFI).By extracting an optimal set of 20 predictors,the proposed framework aims to mitigate redundancy and overfitting while enhancing interpretability.These feature subsets are integrated into support vector regression(SVR),Huber regressors,and k-nearest neighbors(KNN)models to forecast the prices of three leading cryptocurrencies—Bitcoin(BTC/USDT),Ethereum(ETH/USDT),and Binance Coin(BNB/USDT)—across horizons ranging from 1 to 20 days.Model evaluation employs the coefficient of determination(R2)and the root mean squared logarithmic error(RMSLE),alongside a walk-forward validation scheme to approximate real-world trading contexts.Empirical results indicate that incorporating momentum and volatility measures substantially improves predictive accuracy,with particularly pronounced effects observed at longer forecast windows.Moreover,indicators related to volume and trend provide incremental benefits in select market conditions.Notably,an 80%–85% reduction in the original feature set frequently maintains or enhances model performance relative to the complete indicator set.These findings highlight the critical role of targeted feature selection in addressing high-dimensional financial data challenges while preserving model robustness.This research advances the field of cryptocurrency forecasting by offering a rigorous comparison of feature selection methods and their effects on multiple digital assets and prediction horizons.The outcomes highlight the importance of dimension-reduction strategies in developing more efficient and resilient forecasting algorithms.Future efforts should incorporate high-frequency data and explore alternative selection techniques to further refine predictive accuracy in this highly volatile domain. 展开更多

In this paper,the author follows the trail of C.Malabou,Q.Meillassoux,and G.Deleuze and tries to test three philosophical concepts that seem to be particularly threatened in the era of automatic digital reproduction.These three concepts are plasticity(defended for many years by C.Malabou),contingency(reconstructed by Q.Meillassoux),and virtuality(developed by G.Deleuze).The main task of the text will be to reflect on which of these three concepts better protects our thinking against automation and stays faithful to the ideal of creativity.In what sense are plasticity,contingency,and the possibility of virtualization the a priori condition of any transformation,physical or intellectual,affective or conceptual metamorphosis?In what sense are these three concepts the only conditions for the survival of every living being?Would a being without contingency,plasticity,and disposition to virtualization simply be a dead being? 展开更多

The application of generative artificial intelligence(GAI)in the judicial domain represents an innovative approach to achieving digital justice.GAI’s functionalities are primarily exhibited in the enhancement of judicial efficiency,improving the accuracy and fairness of adjudications,promoting the uniform application of the law,and enhancing transparency and engagement in judicial processes.However,these advancements are accompanied by potential risks and challenges in technology,adjudication,and ethics.It is thus essential to strengthen privacy protection during the processing and transmission of data,ensure data security and confidentiality,and establish and refine clear legal norms regarding the roles,responsibilities,and legal obligations of GAI in judicial settings.In addition,ethical guidelines that delineate the behavioral boundaries and value orientations of GAI need to be formulated.Collectively,these elements can form a trinary model of technical controls,legal norms,and ethical constraints,to facilitate the modernization and intelligent development of the judicial system. 展开更多

Addressing issues such as the disconnect between theory and practice and low student engagement in control system education,this paper uses the course“The Working Process of Open-Loop Control Systems”as a case study to explore the integration of AI technology with the“project-guided and task-driven”teaching model.By constructing a four-dimensional teaching framework of“situation-task-activity-evaluation,”AI tools are embedded in project practices such as the construction of a mechanical timed flower watering device and the optimization of a digital timed flower watering device,achieving precision,interactivity,and personalization in the teaching process.Teaching practice demonstrates that this model significantly enhances students’technical awareness,materialization capabilities,and engineering thinking,providing a reference for the teaching reform of technical courses in high school education. 展开更多

Term is a kind of limited language symbols,usually presented in a specific language or text and used to communicate and express ideas.With the globalization of economy,international trade has become more frequent,and chemical products have gradually become the hotspot of international import and export transactions,so the Chinese translation of the names of chemical products has become more important,and accurate translation can better promote the development of the domestic chemical industry and its dialogue and exchange with the international chemical industry.In this paper,we first explore the Chinese translation strategies of the semi-technical words in chemistry,and then investigate the translation strategies for technical words,subdividing the technical words into compounds,derivatives,and acronyms,with a view to providing ideas and references for translations of relevant texts. 展开更多
