The rolling system for stainless steel, particularly in the production of diamond plates, represents a complex industrial control scenario. The process requires precise load distribution to effectively manage pattern height, due to the high strength, hardness, and required dimensional accuracy of the material. This paper addresses the limitations of offline methods, which include heavy reliance on initial conditions, intricate parameter settings, susceptibility to local optima, and suboptimal performance under stringent constraints.

This study systematically investigates the formation mechanism and development characteristics of the "foamy oil" phenomenon during pressure depletion development of high-viscosity crude oil through a combination of physical experiments and numerical simulations. Using Venezuelan foamy oil as the research subject, an innovative heterogeneous pore-etched glass model was constructed to simulate the pressure depletion process, revealing for the first time that bubble growth predominantly occurs during the migration stage. Experimental results demonstrate that heavy components significantly delay degassing by stabilizing gas-liquid interfaces, while the continuous gas-liquid diffusion effect explains the unique development characteristics of foamy oil-high oil recovery and delayed phase transition-from a microscopic perspective.

Background And Aims: Morphological differences between the two genetically close wild radishes, Raphanus raphanistrum and R. pugioniformis, include differences in fruit structure that influence their dispersal ability and within population spatial structure. Here, we tested within- and among-populations genetic variation, hypothesizing that (i) short-distance dispersal of heavy fruits in R.

C-X-C chemokine receptor type 4 (CXCR4) is highly expressed in a range of pathologies, including cancers like multiple myeloma and non-Hodgkin lymphoma, inflammatory diseases such as rheumatoid arthritis, and viral infections like HIV. Currently, the most advanced radiotracer for CXCR4 imaging in clinics is [Ga]PentixaFor. However, its structure is prone to modifications, complicating the development of a specific CXCR4 fluorine-18-labeled tracer with good pharmacokinetic properties.
