摘要:A novel worm gear, named roller enveloping end face internal engagement worm gear, with multiple worm-wheel meshing is proposed to provide multiple outputs with high transmission efficiency and good lubrication for furthering industrial advances. As such, an original worm tr...

摘要:Circulating tumor cell (CTC) count and the host inflammatory response are two independent predictors for patients with various malignant disease. Several inflammation-based indicators have been demonstrated to have prognostic value in many malignant solid tumors, including system...

摘要:In plants, flavonoids play roles not only in development, but also in responses to biotic and abiotic stresses. We analyzed the transcriptome data of NaCl-treated Reaumuria trigyna , a small, highly haloduric desert shrub, focusing on the flavonoid biosynthetic pathway. We identi...

摘要:Abstract(#br)In this paper, we proposed a smoothing iterative method to solve the finite minimax problems based on the exponential penalty function of Kort and Bertsekas (1972). This approach can be viewed as the extension of one conjugate gradient method. Under suitable conditio...

摘要:The volatility of organic aerosols remains poorly understood due to thecomplexity of speciation and multiphase processes. In this study, weextracted humic-like substances (HULIS) from four atmospheric aerosolsamples collected at the SORPES station in Nanjing, eastern China, ...

摘要:Flow instability in a miniature centrifugal pump is numerically simulated with the RANS equations and the SST k-ω turbulence model. The energy gradient method is adopted to analyze the flow instability at design load and two off-design loads, and the results are compared wit...
