Distinct but correct: generating diversified and entity-revised medical response

Science China(Information Sciences) 2024年第3期67卷 94-113页

作者： bin LI bin sun Shutao LI Encheng CHEN Hongru LIU Yixuan WENG Yongping BAI Meiling HU College of Electrical and Information Engineering Hunan University School of Mathematics Sun Yat-sen University JD Technology National Laboratory of Pattern Recognition Institute of AutomationChinese Academy of Sciences Xiangya Hospital of Central South University Teaching and Research Section of Clinical Nursing Xiangya Hospital of Central South University

Medical dialogue generation(MDG) is applied for building medical dialogue systems for intelligent consultation. Such systems can communicate with patients in real time, thereby improving the efficiency of clinical diagnosis. However, predicting correct entities and correctly generating distinct responses remain a great challenge. Inspired by actual doctors’ responses to patients, we consider MDG a two-stage task: entity prediction and dialogue generation. For entity prediction, we design an ent-mac post pre-training strategy by leveraging external medical entity knowledge to enhance the pre-trained model. For dialogue generation, we propose an entity-aware fusion MDG method in which predicted entities are integrated into the dialogue generation model through different encoding fusion mechanisms, using information from different sources. Because the diverse beam search algorithm can produce responses with entities that deviate from the predicted entities, an entity-revised diverse beam search is proposed to correct the entities entailed in the generated responses and make the generated responses more distinct. The experimental results on the China Conference on Knowledge Graph and Semantic Computing 2021(A/B tests) and the International Conference on Learning Representations 2021(online test) datasets show that the proposed method outperforms several state-of-the-art methods, which demonstrates its practicability and effectiveness.

Al-doped ZnO/WO_(3) heterostructure films prepared by magnetron sputtering for isopropanol sensors

Rare Metals 2024年第1期43卷 247-256页

作者： Wei-Xiang Gao Xue-Ting Chang Xiao-Jie Zhu Jun-Feng Li Ying-Chang Jiang Dong-Sheng Wang Chuan-Xiao Yang Shi-bin sun College of Logistics Engineering Shanghai Maritime UniversityShanghai 201306China College of Ocean Science and Engineering Shanghai Maritime UniversityShanghai 201306China Institute of Logistics Science and Engineering Shanghai Maritime UniversityShanghai 201306China

Metal oxide semiconductors(MOSs) are ideal sensing materials for detecting volatile organic compounds due to their low cost, diversity, high stability, and ease of production. However, it remains a grand challenge to develop the MOSs-based gas sensors for sensing isopropanol with desired performance via a simple, effective,and controllable method. Herein, we reported the preparation of the Al-doped Zn O(AZO)/WO_(3) heterostructure films by directly depositing the AZO coating onto the WO_(3) coating using a strategy of magnetron sputtering. The AZO/WO_(3) heterostructure films were constructed by numbers of irregular nanoparticles that were interconnected with each other. The AZO/WO_(3) heterostructure films-based gas sensors exhibited excellent isopropanolsensing performance with high response, promising selectivity, low detection limit, fast response rate, wide detection range, and ideal reproducibility. The promising isopropanol-sensing performance of the AZO/WO_(3) heterostructure films arises mainly from their high uniformity, unique microstructures with high surface roughness,and the construction of the heterostructure between the AZO and WO_(3) coatings. This work provides a versatile approach to prepare the MOSs-based heterostructure films for assembling the gas sensors.

为促进对纯离子模式下电喷雾推力器的深入理解,分析了电喷雾推力器单发射点受力、供液及离子蒸发行为,建立了发射电流理论模型,明确了电压、供液装置流阻等参数对发射电流的影响规律。所得结果与现有实验数据吻合良好。基于所得模型,进而对单发射点顶端用于发射离子的凸起结构进行了瑞利稳定性分析,得到了单发射点稳定发射的电流上限,并分析了流阻对电流上限的影响。结果表明:发射电流为外加电压的二次函数,与供液装置的流阻成反比关系;纯离子模式存在一个稳定发射电流上限,超过此上限,凸起结构便会破碎;流阻越大,发射电流上限越大。

董仲舒在《春秋繁露》一书中有大量关于义利观的论述,其在继承先秦儒家义利观的基础上,进一步结合当时的实际,创造出一套自己的理论体系和哲学范畴。在此基础上,董仲舒利用儒家义利观基本观点来塑造诸如“义利天赋观”“义贵于利观”及“兼利天下人观”等特色价值观。董仲舒对义利观的解读既是他治国理念的外在体现,又是他对经济生活的哲学观察。因此,把董仲舒的义利观与新儒商商业理念结合起来进行考察,对研究董仲舒儒学思想体系在商业领域的表现和价值具有重要意义。
