The spread of renewable energy (RE) generation not only promotes the economy and environmental protection, but also brings uncertainty to the power system. As the integration of hydrogen and electricity can effectively mitigate the fluctuation of RE generation, an electricity-hydrogen integrated energy system is constructed. Then, this paper studies the source-load uncertainties and corresponding correlation as well as the electricity-hydrogen price uncertainties and corresponding correlation. Finally, an optimal scheduling model considering economy, environmental protection, and demand response (DR) is proposed. The simulation results indicate that the introduction of the DR strategy and the correlation of electricity-hydrogen price can effectively improve the economy of the system. After introducing the DR, the operating cost of the system is reduced by 5.59%, 10.5%, and 21.06% in each season, respectively. When considering the correlation of EP and HP, the operating cost of the system is reduced by 4.71%, 6.47%, 1.4% in each season, respectively.

Early Palliative Care Following Aborted Cancer Surgery: Results of a Prospective Feasibility Trial.
Ann Surg Open
December 2024
Division of Palliative Medicine, Department of Internal Medicine, The Ohio State University Wexner Medical Center, Columbus, OH.
Background: Although resection is generally necessary for curative-intent treatment of most solid organ cancers, surgery is occasionally aborted due to intraoperative findings. Following aborted cancer surgery, patients have unique care needs that specialized palliative care (PC) providers may be best equipped to manage. We hypothesized that early ambulatory PC referral following aborted cancer surgery would be feasible and acceptable.

December 2024
Department of Radiation Oncology, Sun Yat-sen University Cancer Center, State Key Laboratory of Oncology in South China, Collaborative Innovation Center for Cancer Medicine, Guangdong Key Laboratory of Nasopharyngeal Carcinoma Diagnosis and Therapy, Guangzhou, China. Electronic address:
Purpose: To establish an artificial intelligence (AI)-empowered multistep integrated (MSI) radiation therapy (RT) workflow for patients with nasopharyngeal carcinoma (NPC) and evaluate its feasibility and clinical performance.
Methods And Materials: Patients with NPC scheduled for MSI RT workflow were prospectively enrolled. This workflow integrates RT procedures from computed tomography (CT) scan to beam delivery, all performed with the patient on the treatment couch.

Magnetic resonance imaging (MRI) is an essential tool in pediatric imaging. It offers detailed, high-contrast images without ionizing radiation, making it particularly suitable for children. Creating an efficient MRI service is challenging given the balancing priorities of image quality and scan time and the overlying logistical challenges, including MRI safety protocols, the need for sedation in certain patient populations, and flexibility to accommodate patients at different phases of care.
