Th...A new reliability-based multidisciplinary design optimization （RBMDO） framework is proposed by combining the single-loop-based reliability analysis （SLBRA） method with multidisciplinary feasible （MDF） method. The Kriging approximate model with updating is introduced to reduce the computational cost of MDF caused by the complex structure. The computational efficiency is remarkably improved as the lack of iterative process during reliability analysis. Special attention is paid to a turbine blade design optimization by adopting the proposed method. Results show that the method is much more efficient than the commonly used double-loop based RBMDO method. It is feasible and efficient to apply the method to the engineering design.展开更多

文摘BACKGROUND Hepatocellular carcinoma(HCC)ranks as the sixth most common cancer and the third-leading cause of cancer-related deaths worldwide.The multidisciplinary tumor board(MDTB)has been recognized for improving outcomes in cancer management,but its role in patients with HCC undergoing liver transplantation(LT)remains underexplored.AIM To evaluate the impact of an MDTB on survival outcomes in patients with HCC undergoing LT.METHODS We retrospectively analyzed 393 patients with HCC who underwent LT at our institution from October 2015 to October 2021.Patients were categorized into the MDTB and non-MDTB groups.We compared preoperative and postoperative characteristics,overall survival(OS),and disease-free survival(DFS)between the two groups.RESULTS Within the University of California,San Francisco(UCSF)criteria,no significant differences in OS and DFS were noted between the MDTB and non-MDTB groups.However,for patients who exceeded the UCSF criteria,the MDTB group exhibited a substantial improvement in both OS and DFS.The 1-year,3-year,and 5-year OS rates for the MDTB group in this subgroup were 88.68%,75.29%,and 61.78%,respectively,compared to 83.02%,64.07%,and 38.25%,respectively in the non-MDTB group.Similarly,DFS rates were 89.47%,71.35%,and 63.52%,respectively,vs 82.18%,53.78%,and 34.04%,respectively.CONCLUSION The MDTB approach was particularly beneficial for patients with HCC exceeding the UCSF criteria,significantly improving OS and DFS.These findings advocate for integrating MDTB into clinical practice for optimizing the management of high-risk patients with HCC undergoing LT.
文摘This letter discusses the critical yet underrecognized intersection of chronic renal insufficiency and Nocardia brasiliensis skin infection in the case reported by Zhang et al,emphasizing the diagnostic challenges and therapeutic complexities in the context of advanced age,comorbidities,and immunocompromised populations.The study’s strengths included its integration of immunological profiling and precision medicine,demonstrating that a tailored low-dose trimethoprimsulfamethoxazole regimen with pharmacokinetic monitoring can improve outcomes in geriatric patients with chronic renal insufficiency while mitigating nephrotoxicity risks.However,its limitations included a single-case design,reliance on phenotypic diagnostics,and the lack of information regarding comorbidity interactions.The findings support the use of advanced molecular tools for rapid pathogen identification and identification of co-infection.Future studies should prioritize elucidating the synergistic effects of chronic kidney disease-uremia and immunosuppression on Nocardia colonization,developing biomarkers for early detection,and conducting global epidemiological studies in endemic regions.This case underscores the importance of interdisciplinary collaboration and innovative diagnostics to optimize management of nocardiosis in vulnerable populations.

文摘Unlike traditional propeller-driven underwater vehicles,blended-wing-body underwater gliders(BWBUGs)achieve zigzag gliding through periodic adjustments of their net buoyancy,enhancing their cruising capabilities while mini-mizing energy consumption.However,enhancing gliding performance is challenging due to the complex system design and limited design experience.To address this challenge,this paper introduces a model-based,multidisciplinary system design optimization method for BWBUGs at the conceptual design stage.First,a model-based,multidisciplinary co-simulation design framework is established to evaluate both system-level and disciplinary indices of BWBUG performance.A data-driven,many-objective multidisciplinary optimization is subsequently employed to explore the design space,yielding 32 Pareto optimal solutions.Finally,a model-based physical system simulation,which represents the design with the largest hyper-volume contribution among the 32 final designs,is established.Its gliding perfor-mance,validated by component behavior,lays the groundwork for constructing the entire system’s digital prototype.In conclusion,this model-based,multidisciplinary design optimization method effectively generates design schemes for innovative underwater vehicles,facilitating the development of digital prototypes.

文摘A new reliability-based multidisciplinary design optimization （RBMDO） framework is proposed by combining the single-loop-based reliability analysis （SLBRA） method with multidisciplinary feasible （MDF） method. The Kriging approximate model with updating is introduced to reduce the computational cost of MDF caused by the complex structure. The computational efficiency is remarkably improved as the lack of iterative process during reliability analysis. Special attention is paid to a turbine blade design optimization by adopting the proposed method. Results show that the method is much more efficient than the commonly used double-loop based RBMDO method. It is feasible and efficient to apply the method to the engineering design.

文摘Design for modem engineering system is becoming multidisciplinary and incorporates practical uncertainties; therefore, it is necessary to synthesize reliability analysis and the multidisciplinary design optimization （MDO） techniques for the design of complex engineering system. An advanced first order second moment method-based concurrent subspace optimization approach is proposed based on the comparison and analysis of the existing multidisciplinary optimization techniques and the reliability analysis methods. It is seen through a canard configuration optimization for a three-surface transport that the proposed method is computationally efficient and practical with the least modification to the current deterministic optimization process.
