Abstract: A method is provided for synthesizing PLA/apatite composites with improved mechanical strength. In one aspect, a calcium-phosphate/phosphonate hybrid shell is developed to incorporate more reactive hydroxyl groups onto hydroxyapatite (HA) particles. PLA is covalently bonded to HA calcium phosphate hybrid shell, creating a strong interphase between HA and PLA, thus significantly improve the mechanical strength in comparison to that of non-modified HA.

Abstract: A method, computer program, and computer system is provided for fault detection in an electrical network. An inductance between a reference point and a fault is determined at a first time based on measuring a fault current. A resistance between the reference point and the fault may be determined at a second time based on measuring a differential of the fault current as zero. A location of the fault may be identified based on the inductance and the resistance.

Abstract: The present disclosure provides methods related to treating triple-negative breast cancer (TNBC) in a mammal by administering salvianolic acid B (or a salt or solvate thereof) to promote ceramide-mediated apoptosis. In one form, the ceramide-mediated apoptosis of TNBC cells occurs by decreasing the level of one or more of glucosylceramide synthase and GM3 synthase in the subject through the use of an effective amount of salvianolic acid B. In another aspect, salvianolic acid B or its pharmaceutically acceptable salt or solvate is used as a medicament or in the manufacture of a medicament for treating TNBC.
Abstract: An apparatus, the apparatus includes a simulator, an interface, and a microgrid. The simulator includes a model of a physical electrical network. The interface is coupled to the simulator. The microgrid is coupled to the interface and includes a plurality of electrical elements that represent aspects of the physical electrical network. The simulator receives requests to analyze performance of the physical electrical network, responsively produces signals that are converted to control signals by the interface and applied to the microgrid, the microgrid providing feedback.
