Nitrogen removal is a critical process in water treatment plants(WIPs)and wastewater treatment plants(WWTPs).The recent discovery of a novel bacterial process,complete ammonia oxidation(comammox,CMX),has refuted a century-long perception of the two-step conversion of NH3to NO3-.Compared with canonical nitrifiers,CMX bacteria offer undeniable advantages,such as a high growth yield propensity and adaptability to nutrient-and growth-limiting conditions,which collectively draw attention to validate the aptness of CMX bacteria to wastewater *** there has been no comprehensive review on the relevance of CMX bacteria for sustainable water and wastewater treatment,this review is intended to discuss the roles and applications of CMX in the removal of nitrogen and pollutants from water and *** took into account insights into the metabolic versatilities of CMX bacteria at the clade and subclade *** focused on the distribution of CMX bacteria in engineered systems,niche differentiation,co-occurrence and interactions with cano nical nitrifiers for a better understanding of CMX bacteria in terms of their *** details on the reactor adaptability and stress response of CMX bacteria are *** potential of CMX bacteria to degrade micropollutants either directly or co-metabolically was evaluated,and these insights would be an indispensable advantage in opening the doors for wider applications of CMX bacteria in ***,we summarized future directions of research that are imperative in improving the understanding of CMX biology.

竞争中立规则,要求政府对公私企业的监管保持中立,不偏不倚,以确保公私企业公平竞争。最初,该规则的适用范围仅限于国有企业的经营行为。但近年来,美欧部分国家将其扩展到私营企业:将他国国有企业认定为公共机构,将国有企业与私有企业的正常商业交易,视为政府对私有企业的补贴,要求受补贴的私有企业适用该规则;或直接要求部分私有企业适用该规则。欧美竞争中立规则适用范围的扩张,会对我国对外投资贸易产生严重影响。我国应明确商业性国有企业的范畴;在国际贸易和投资争端解决中,坚决否认将国有企业认定为公共机构;坚持竞争中立规则不适用于私有企业;充分利用竞争中立规则例外条款,维护我国企业的海外贸易利益。

目的基于计算机的胸腔X线影像疾病检测和分类目前存在误诊率高,准确率低的问题。本文在视觉Transformer(vision Transformer,ViT)预训练模型的基础上,通过迁移学习方法,实现胸腔X线影像辅助诊断,提高诊断准确率和效率。方法选用带有卷积神经网络(convolutional neural network,CNN)的ViT模型,其在超大规模自然图像数据集中进行了预训练;通过微调模型结构,使用预训练的ViT模型参数初始化主干网络,并迁移至胸腔X线影像数据集中再次训练,实现疾病多标签分类。结果在IU X-Ray数据集中对ViT迁移学习前、后模型平均AUC(area under ROC curve)得分进行对比分析实验。结果表明,预训练ViT模型平均AUC得分为0.774,与不使用迁移学习相比提升了0.208。并针对模型结构和数据预处理进行了消融实验,对ViT中的注意力机制进行可视化,进一步验证了模型有效性。最后使用Chest X-Ray14和CheXpert数据集训练微调后的ViT模型,平均AUC得分为0.839和0.806,与对比方法相比分别有0.014~0.031的提升。结论与其他方法相比,ViT模型胸腔X线影像的多标签分类精确度更高,且迁移学习可以在降低训练成本的同时提升ViT模型的分类性能和泛化性。消融实验与模型可视化表明,包含CNN结构的ViT模型能重点关注有意义的区域,高效获取胸腔X线影像的视觉特征。
