Abstract: Provided is a glutamic acid (Glu)-urea compound and a preparation method and use thereof. The Glu-urea compound and the nuclide-targeted probe have excellent in vivo biological properties and show a high specific uptake in lesions with high expression of a prostate-specific membrane antigen (PSMA) protein. The compound and probe have a high target/non-target ratio, low non-specific background activity, and significantly-enhanced tumor uptake and retention time. The compound and probe are suitable for use in the nuclide therapy and imaging of tumors, and can also reduce unnecessary radiation damage to normal tissues and organs. The compound and probe can also overcome the shortcomings such as low target organ uptake and short retention time of small-molecule PSMA, and improve the effects of PSMA-targeted nuclide therapy and imaging, thus exhibiting a potential to be widely used in clinical applications.

Abstract: A fully distributed island micro-grid attack elasticity control system and method are provided. The method includes following specific steps: collecting basic information of a local AC micro-grid bus of a distributed power generation unit and basic information of a neighbor distributed power generation unit connected through a directed communication topology; predicting, based on a dynamic equation of the distributed power generation unit, a sequence of states thereof within a set period of time, namely, the predicted sequence of states; judging whether a system is under attack according to a comparison result of the predicted sequence of states and a real-time state sampling value of a micro-grid, to obtain a sequence of optimal auxiliary control inputs ui*; and calculating an optimal angular frequency reference value ?i* at the next time point according to the sequence of optimal auxiliary control inputs ui*.

Abstract: Systems and methods of augmented reality mapping are disclosed. Tags associated with collections of interest, areas of interest, and/or points of interest may be superimposed over a video feed of a user device. In response to movement of the user device a single tag associated with a collection of interest may replace a plurality of tags associated with a plurality of points of interest within the collection of interest.
