    Abstract Minerals are very significant components of coal from both academic and practical perspectives. Minerals may react when the coal is burned, either forming an ash residue, or, in many cases, releasing volatile components, or being needed to be removed as slag from the blast furnace during metallurgical processing. Minerals in coal can also be a source of unwanted abrasion, stickiness, corrosion, or pollution associated with coal handling and use. Minerals in coal, in some cases, are major carriers of valuable metals, such as Ga, Al, and rare earth elements, and these coals with highly-evaluated valuable metals have the potential to be raw sources for industry use. From the genetic point of view, the minerals in coal are products of the processes associated with peat accumulation and rank advance, as well as other aspects of epigenetic processes, and, thus, the minerals in coal can provide information on the depositional conditions and geologic history of individual coal beds, coal-bearing sequences, and regional tectonic evolution. This Special Issue, "Minerals in Coal", focuses on providing an up-to-date series of papers, covering research and technological developments in the nature, origin, and significance of the minerals in coal, and productions derived from combustion and gasification

    Abstract The pooling layer in convolutional neural networks plays a crucial role in reducing spatial dimensions, and improving computational efficiency. However, standard pooling operations such as max pooling or average pooling are not suitable for all applications and data types. Therefore, developing custom pooling layers that can adaptively learn and extract relevant features from specific datasets is of great significance. In this paper, we propose a novel approach to design and implement customizable pooling layers to enhance feature extraction capabilities in CNNs. The proposed T-Max-Avg pooling layer incorporates a threshold parameter T, which selects the K highest interacting pixels as specified, allowing it to control whether the output features of the input data are based on the maximum values or weighted averages. By learning the optimal pooling strategy during training, our custom pooling layer can effectively capture and represent discriminative information in the input data, thereby improving classification performance. Experimental results show that the proposed T-Max-Avg pooling layer achieves good performance on three different datasets. When compared to LeNet-5 model with average pooling, max pooling, and Avg-TopK methods, the T-Max-Avg pooling method achieves the highest accuracy on CIFAR-10, CIFAR-100, and MNIST datasets.

    Abstract [Purpose/Significance] This paper aims to explore whether there are differences in the title and abstract, citation content, and full-text content on research topic, and analyze whether the topic content in the title and abstract can reveal the research content of the full text and the effect of the citation content on the content of the citing literature, so as to provide theoretical support for analyzing the research content of the full text based on the title and abstract of the literature. [Method/Process] This paper conducts an empirical study using Chinese journal papers in the field of COVID-19, extracts feature words from the titles and abstracts, citations and full-text contents of the literature, uses the clustering algorithm to cluster the feature words, and then uses manual interpretation to identify the research topics, and conducts a comparative study to analyze the topic differences among the three parts. [Results/Conclusions] The results show that: the research topics are different in the title and abstract, citation content and full-text content of the literature; compared with the title and abstract, the full text contains more topic content, but the difference in the topic content is small, so the topic content in the title and abstract can be used to represent the research content of the full text; the content of the citation is related to the topic of the citing literature, and they can complement each other.

    Abstract The electrochemical interfacial interaction of electrode materials with liquid electrolytes in electrochemical energy storage systems including supercapacitors, metal ion batteries, and metal-based batteries have become a research hotspot and play a decisive role in electrochemical energy storage in terms of charging and discharging reaction principles of the electrode materials. However, there is still a long way from maturity due to the challenges related to the unsatisfactory electrolyte-philicity of electrode materials. In the last 20 years, several studies have been directed at discovering strategies to improve the electrolyte-philicity of electrode materials, optimizing the electrochemical interfacial interaction of the electrode materials with liquid electrolytes and exploring the relationship between electrolyte-philicity and electrochemical energy storage performance in the charging and discharging processes of the electrode materials. Unfortunately, the systematic and in-depth understanding of electrolyte-philicity of electrode materials has not been grasped in electrochemical energy storage systems. In this review, we highlight the fundamental scientific understanding of electrolyte-philicity of electrode materials and the relationship among electrolyte-philicity and electrochemical energy storage performance of electrode materials. The definition of electrolyte-philicity of electrode materials is first proposed based on the interaction between the electrode material and electrolyte ions as the essence of electrochemical energy storage of the electrode materials. More important, how the electrolyte-philicity of electrode materials optimizes the electrochemical energy storage performance of the electrode materials has been expounded from the rapid and effective contact of the electrode materials with electrolyte ions under uncharged state to electrochemical interfacial interaction between the electrode materials and electrolytes under the charged state. Then, the fundamental physical and chemical interactions so that the electrode materials may be electrolyte-philic are summarized, and the mechanisms of improving the electrolyte-philicity of electrode materials by surface modification are illustrated based on those interactions. Finally, the future perspectives for important areas of electrolyte-philicity of electrode materials are presented.

    Abstract Although cirrhosis is one of the most common causes of portal hypertension, noncirrhotic portal hypertension can result from hemodynamic perturbations occurring in the prehepatic, intrahepatic, and posthepatic circulation. Intrahepatic portal hypertension can be further subclassified relative to the hepatic sinusoids as presinusoidal, sinusoidal, and postsinusoidal. For many of these differential diagnoses, the etiology is known but the cause of idiopathic noncirrhotic portal hypertension, recently included in porto-sinusoidal vascular disease (PSVD), remains poorly understood. Herein, we discuss the diagnostic pathological features of noncirrhotic portal hypertension, with an emphasis on PSVD.

    Abstract Concentrations of trace elements in coal and coal combustion products are commonly analyzed by inductively coupled plasma-mass spectrometry (ICP-MS) due to large number of elements detected and the relatively the low detection limits of this technique. Like other geological samples, complete dissolution of coal and coal combustion products is also essential for accurate ICP-MS results. In this study, Sr and Ba in coal and coal combustion products (fly and bottom ashes) from two coal-combustion power plants from North China analyzed by XRF and ICP-MS were comparatively studied. The concentrations of Sr and Ba analyzed by ICP-MS, when a mixture of acids (2 ml HF + 5 ml HNO
