"一带一路"倡议使向西开放战略进入以内陆开放为趋势的深度推进阶段,随着西部地区经济快速增长,资源耗竭和生态消费已经成为制约西部地区经济增长的桎梏。西部地区生态环境的先天脆弱性决定了其在实现地区经济快速增长的过程中应该强化产业共生和发展循环经济。基于循环经济的产业生态化建设思路是破解我国西部地区经济生态化发展中资源环境等多重制约的必然选择。本文基于循环经济的思想,以生态工业园区的热电转换过程为例,通过不确定性建模与优化的研究方法对西部地区生态工业园进行优化设计,解析工业园区产业生态化循环层面的实现方案,并以此为借鉴,提出推进西部地区生态工业园区建设的实施方案及进一步推进生态文明发展的对策。 展开更多

To the Editor:Artificial intelligence(AI)is revolutionizing the biomedical field by enabling advanced data analysis,predictive modeling,and personalized medicine,driving breakthroughs in diagnosis,treatment,and drug discovery.In pursuit of this goal,researchers are attempting to develop AI-based algorithms and establish models for use in clinical settings.Key challenges in this pursuit include ensuring the models’accuracy and consistency and addressing issues such as the interpretability of AI decisions,integration into existing clinical workflows,and ethical considerations like data privacy.Additionally,the AI model lies in the quality and diversity of training data—robust models require diverse and representative datasets to ensure generalizability across different patient populations,reduce dependence on extensive labeled data,and remain resilient to domain shifts,enabling adaptation to new and unseen cases.Nevertheless,this field continues to grow,especially in image-based AI models for diagnosing diseases,such as cardiovascular diseases. 展开更多

Modifying solution viscosity is a key functional application of polymers,yet the interplay of molecular chemistry,polymer architecture,and intermolecular interactions makes tailoring precise rheological responses challenging.We introduce a computational framework coupling topology-aware generative machine learning,Gaussian process modeling,and multiparticle collision dynamics to design polymers yielding prescribed shear-rate-dependent viscosity profiles.Targeting thirty rheological profiles of varying difficulty,Bayesian optimization identifies polymers that satisfy all lowand most medium-difficulty targets by modifying topology and solvophobicity,with other variables fixed.In these regimes,wefind and explain design degeneracy,where distinct polymers produce nearidentical rheological profiles.However,satisfying high-difficulty targets requires extrapolation beyond the initial constrained design space;this is rationally guided by physical scaling theories.This integrated framework establishes a data-driven yet mechanistic route to rational polymer design. 展开更多

Enhanced oil recovery by CO2 injection technology(CO2-EOR)plays a crucial role in enhancing oil production and the permanent sequestration of anthropogenic CO2 in depleted oil reservoirs.However,the availability of CO2 in oil field locations and its mobility in contrast with reservoir fluids are prime challenges in CO2-EOR.The cost of CO2 and its availability at the oil fields has prompted investigations on efficient injection of CO2 at the fields to achieve the best sweep efficiency possible.Injection strategies such as water-alternating-gas(WAG),simultaneous vertical and horizontal WAG,simultaneous water injection into the aquifer and vertical WAG,water and gas injection simultaneously but separately(SS-WAG),and water and gas injection simultaneously but not separately(SNS-WAG)play a significant role,as well as the purity of CO2.In this work,the significance of the above criteria was investigated indi-vidually and in combination.The coupled sequence of injection rate,soaking time,WAG ratio,and purity of injected CO2 for enhancement of oil production were delineated.A realistic reservoir simulation model conceptualizing the CO2-EOR system with five spot injection patterns was developed by the company CMG.The history-matched model that was developed was used to investigate the sensitivity of the coupled effects to the criteria listed above on oil recovery.Numerical investigations quantitatively emphasized that purity and soaking time of CO2 have an inverse effect in the oil production rate and that SNS-WAG resulted in a better oil production rate than SS-WAG. 展开更多
