  • Publication number: 20260208612
    Abstract: A bi-level optimization (BLO) method based on a truck mobile charging station (TMCS) leasing mode includes the steps of: establishing a bi-level game model based on a TMCS leasing mode; introducing a Wasserstein distance distributionally robust model based on chance constraints through a distributionally robust optimization (DRO) strategy; balancing economy and robustness of the bi-level game model via the Wasserstein distance distributionally robust model; solving a TMCS operator (TMCO) model through a genetic algorithm (GA) to obtain a revenue-maximizing configuration and a leasing price; and solving a charging facility operator (CFO) two-stage distributionally robust chance-constrained optimization (DRCC) model via a nested column-and-constraint generation (NC&CG) algorithm to obtain a leasing plan and a scheduling strategy with maximum utility. Demands of various operators can be effectively balanced, which can improve the economy of CFOs while ensuring the revenue of TMCOs.

  • Publication number: 20260137676
    Abstract: A piperazine substituted phenol derivative and its applications in pharmaceutical chemistry are provided. The compound, depicted by formula I, exhibits excellent salt formation properties and water solubility, meeting formulation requirements. It also has a low minimum effective anesthetic dose, enabling rapid onset and recovery. This addresses the drawbacks of propofol and ciprofol prodrugs and lipid emulsions. The compound shows promise in developing drugs with sedative, hypnotic, and/or anesthetic effects, as well as in drugs for controlling status epilepticus.

  • Publication number: 20260134357
    Abstract: Related to the field of charging infrastructure optimization, a method for online coordinated optimization scheduling of truck mobile charging stations. A two-stage framework is proposed: (1) offline training stage, where a multi-period optimization decision model for TMCSs is constructed, and a look-ahead rolling horizon-value function approximation (LRH-VFA) algorithm is then developed to iteratively learn from historical EV charging data, considering the impact of current-period decisions on future profit; and (2) online scheduling stage, where TMCS scheduling decisions are dynamically updated based on the approximate value function obtained from offline training, along with short-term forecasts and real-time information. The method effectively accounts for the impact of uncertain EV charging demand on TMCS scheduling, dynamically adjusting decisions based on real-time updates.
