Abstract: Disclosed is a method for inducing gelation and biomimetic mineralization of silk fibroin solution by means of alkalinephosphatase. The method introduces a micro-molecule polypeptide which is sensitive to ALP and has good biocompatibility and self-assembly characteristic to serve as a gelator precursor. The micro-molecule polypeptide can, under the catalytic action of the ALP, remove phosphate groups on molecules to generate NY and trigger supramolecular self-assembly, thereby synergistically inducing co-self-assembly with SF, and ultimately resulting in rapid formation of SF hydrogel. The ALP wrapped in an SF-NY hydrogel network still maintains its catalytic activity, and releases free phosphate ions by catalyzing β-glycerophosphate to induce the formation of apatite minerals in the gel. Due to the mild gelation process and the formation of apatite minerals in a gel matrix, the SF gel subjected to biomimetic mineralization not only can be used as a biomimetic scaffold to promote adhesion, proliferation and osteogenic differentiation of rat mesenchymal stem cells in vitro, but also can promote natural healing of femoral defect in a rat model.

Title: Component-level non-iterative construction method for on-board real-time model of variable cycle engine
Inventor: LU FENG
IPC: G06F30/15
Filed: 2021-01-07
Abstract: Provided is a component-level non-iterative construction method for an on-board real-time model of a variable cycle engine. The component-level non-iterative construction method for an on-board real-time model of a variable cycle engine is provided by using an existing nonlinear component-level dynamic universal model of a variable cycle engine and by combining same with a modeling thought of an LPV model of an aircraft engine. In an original nonlinear component-level universal model of a variable cycle engine, components are connected together by means of a set of nonlinear coworking equations, and characteristic parameters of each component are obtained by iteratively solving the set of nonlinear coworking equations. This process of iteratively solving a set of nonlinear equations consumes a long time in a model running process. In the component-level non-iterative method for a variable cycle engine, this process of iteratively solving a set of nonlinear equations is replaced by an LPV model, such that the time consumed by a variable cycle engine model can be remarkably shortened with less precision loss, and the real-time performance of the variable cycle engine model is improved.
