A research paper by scientists at Beijing Friendship Hospital develop a systematic approach for automated ossicular-chain segmentation and measurement using ultra-high-resolution computed tomography (U-HRCT).

Exciton polaritons are hybrid light-matter quantum states arising from strong coupling, offering a unique platform for exploring macroscopic quantum phenomena. However, how the coherence of external driving laser field is transferred to polaritons has remained an open question. Recently, the team of Prof. Jian Wu at East China Normal University achieved a critical breakthrough in this area. By combining femtosecond angle-resolved spectroscopic imaging with interferometry, they directly observed the transfer of laser coherence to resonantly excited exciton polaritons within hundreds of femtoseconds at room temperature. They further uncovered the physical mechanism by which non-resonant polaritons lose coherence under high pump power due to a decoherence process mediated by the exciton reservoir. These findings have been published under the title "Femtosecond coherence dynamics of exciton polaritons" in National Science Review. Haoyuan Jia, a PhD candidate at East China Normal University, is the first author, with co-corresponding authors including Prof. Jian Wu and Prof. Hui Li (East China Normal University), Dr. Junhui Cao (Moscow Institute of Physics and Technology), and Prof. Tim Byrnes (NYU Shanghai).

This study systematically evaluates the effects of straw returning practices—specifically the timing, depth, and amount—on the occurrence of major maize diseases (northern leaf blight and ear rot), the infestation by Ostrinia furnacalis, and grain yield in dryland farming. It provides practical guidelines for tailoring straw management strategies to differentially manage airborne diseases, soil-borne pathogens, and overwintering pests.
