The early Silurian conodonts are firstly described and illustrated from western Thailand. Samples were collected from the Kroeng Kravia Forest Park area for conodont and lithofacies analyses. An upper Telychian Lower Pterospathodus amorphognathoides amorphognathoides Subzone is recognized for the studied succession. Three lithofacies were identified from the carbonate succession, including stromatolite-thrombolite limestone, nodular limestone, and red limestone. Both analyses on lithofacies and conodont assemblages indicate a deeper marine depositional environment. The conodont fauna in the study area is similar to that from Baoshan of Yunnan Province and Langao of Shaanxi Province in West China and resembles that from similar depositional environments in Australia, Laurentia, and peri-Gondwana, suggesting good connections among these regions by ocean currents.

The reform stems from honesty and determination. Since 2005, organ donation and transplantation in China has undergone thorough reform, which complies with legislation requirements and ethical principles established by the World Health Organization(WHO). Reform in China has demonstrated the unwavering confidence and utmost determination of the Chinese government and the Chinese transplantation community. The year 2015 marked a historic turning point when voluntary donations from Chinese citizens became the sole legitimate source for organ transplantation. Since 2015, China has gradually established and refined the “Chinese Mode” and “China System” for organ donation and transplantation, fulfilling its political pledge of reform, and has garnered international recognition, and fostered a social culture which promotes organ donation. This article reviewed the history of reform on organ donation and transplantation in China, presented a new pattern of establishment of organ donation system in the new era of the country, and the direction of advances in the future.

Nuclear magnetic resonance (NMR) spectroscopy serves as a robust non-invasive characterization technique for probing molecular structure and providing quantitative analysis, however, further NMR applications are generally confined by the low sensitivity performance, especially for heteronuclear experiments. Herein, we present a lightweight deep learning protocol for high-quality, reliable, and very fast noise reduction of NMR spectroscopy. Along with the lightweight network advantages and fast computational efficiency, this deep learning (DL) protocol effectively reduces noises and spurious signals, and recovers desired weak peaks almost entirely drown in severe noise, thus implementing considerable signal-to-noise ratio (SNR) improvement. Additionally, it enables the satisfactory spectral denoising in the frequency domain and allows one to distinguish real signals and noise artifacts using solely physics-driven synthetic NMR data learning. Besides, the trained lightweight network model is general for one-dimensional and multi-dimensional NMR spectroscopy, and can be exploited on diverse chemical samples. As a result, the deep learning method presented in this study holds potential applications in the fields of chemistry, biology, materials, life sciences, and among others. © Editorial office of Acta Physico-Chimica Sinica.

针对新型电力系统背景下主动配电网存在的实时量测数据少、量测不确定性强等问题,提出一种基于σ-预算的主动配电网两阶段区间状态估计方法。在第一阶段,构建混合整数线性规划模型,采用伪量测数据替代辨识出的量测不良数据,提高区间状态估计算法的鲁棒性;在第二阶段,基于广义方和根误差合成理论建立基于σ-预算的量测不确定性集,作为区间状态估计模型的输入可行域,以克服区间估计算法高保守性的问题;结合稀疏矩阵构建区间状态估计线性优化迭代模型,从而更加高效地求解状态变量的区间上下界。通过修改的IEEE 33节点系统、IEEE 118节点系统和江苏某市26节点配电网仿真验证了所提方法的有效性。

在时下的无监督深度哈希研究领域中,基于对比学习而提出的方法占主流地位.但是对比学习所采用的随机抽取负样本方式,会带来采样偏差问题,从而对图像检索精度造成负面影响.为解决以上问题,本文提出了一种基于偏差抑制对比学习的无监督深度哈希(unsupervised deep hashing based on bias suppressing contrastive learning,BSCDH).本文在对比学习框架的基础上提出了偏差抑制方法(bias suppression,BSS),将错误负样本近似为极困难负样本,并设计了偏差抑制系数来抑制极困难负样本从而缓解采样偏差的负面影响.本文根据当前负样本与查询样本的相似度来确定其对应的抑制系数取值,并引入当前负样本与邻近的聚类中心间的距离关系对抑制系数进行取值修正,降低正常负样本被过度抑制的可能性.最终BSCDH的64位哈希码mAP@5000指标在CIFAR-10、FLICKR25K、NUS-WIDE数据集上分别达到0.696、0.833、0.819,相较baseline具有显著的性能优势.本文开展的大量实验证明了BSCDH在无监督图像检索方法中拥有较高的检索精度,且能有效应对采样偏差问题.
