  • Discrete element method (DEM) contact model building method for reflecting weakening of seepage on rock and soil mass strength
    Patent number: 11977825
    Abstract: A discrete element method contact model building method includes: selecting a filling body in a disaster-causing structure to obtain a change rule of cumulative loss of the filling body; performing test simulation, and determining a relation function of each group of corresponding mesoscopic mechanical parameters in each time period and mesoscopic parameters of a DEM contact model representing a change rule of macroscopical parameters of the filling body; embedding each mesoscopic parameter relation function into an existing particle contact model, performing test simulation, and updating a fracture failure criterion of the contact model according to a corresponding relation of macro-mesoscopic strength during model failure; and based on a seepage failure indoor test, building a seepage failure discrete element calculation model, and simulating the seepage failure process of a rock and soil mass by using the obtained particle contact model and the fracture criterion of the particle contact model.

  • Herbicide-resistant proteins, encoding genes, and uses thereof
    Patent number: 9464117
    Abstract: Some embodiments of the present invention can include herbicide-resistant proteins, coding genes, and uses thereof. Certain herbicide-resistant proteins can comprises: (a) a protein consisting of an amino acid sequence shown in SEQ ID NO: 2; or (b) a protein consisting of an amino acid sequence at least 90% identical to that set forth in SEQ ID NO: 2. Other herbicide-resistant proteins of this disclosure can be suitable for expression in plants, can have resistance to herbicides (e.g., to phenoxy auxinherbicides), or both.
