    Abstract: Understanding fluid flow behavior in coal is of great significance for coal-bed methane exploration. X-ray CT and image segmentation have been widely used to extract pore network and generate flow field grids for flow simulation in coal samples. However, these techniques have fundamental limitations for the multi-scale characterization of coal samples, where the sub-voxel scale details could not be resolved for millimeter scale macroscopic samples. This makes it difficult to simulate the multi-scale flow behavior of fluid transport in coal sample with varying pore scales. The primary challenge is to make connection between simulation results of different scales. In the present work, multi-scale fluid flow in an anthracite coal sample was simulated by incorporating the data-constrained modeling (DCM), molecular dynamics (MD) method and partially-percolating lattice Boltzmann method (PP-LBM). In this multi-scale simulation method, three-dimensional (3D) flow field containing multi-scale structural information of the coal sample was generated by combining DCM with multi-energy synchrotron radiation CT. Multi-scale fluid flow was simulated by PP-LBM. In PP-LBM, an effective percolation fraction parameter which represents the effective volume fraction of the fluid that contributed to the flow for the voxel was used as a bridge to connect the fluid flow pattern of sub-voxel scales and voxel scales. The effective percolation fraction of a voxel versus its porosity was derived by MD simulations at the sub-voxel size level. The 3D distribution of fluid speed in the coal sample and its permeability were obtained by this multi-scale method. The numerical results are consistent with published laboratory measurements. Our proposed approach incorporated multi-scale effects and offered a more realistic fluid transport simulation method for a coal sample with varying pore size scales from the microscopic to macroscopic level. The method would be applicable for fluid transport simulations for other multi-scale porous materials.

    Abstract: In this study, a multiobjective nonfragile control is proposed for a class of stochastic Takagi and Sugeno (T–S) fuzzy systems with mixed time delays to guarantee the optimal H2 and H∞ performance simultaneously. Firstly, based on the T–S fuzzy model, two form of nonfragile state feedback controllers are designed to stabilize the T–S fuzzy system, that is to say, nonfragile state feedback controllers minimize the H2 and H∞ performance simultaneously. Then, by applying T–S fuzzy approach, the multiobjective H2/H∞ nonfragile fuzzy control problem is transformed into linear matrix inequality (LMI)-constrained multiobjective problem (MOP). In addition, we efficiently solve Pareto optimal solutions for the MOP by employing LMI-based multiobjective evolution algorithm (MOEA). Finally, the validity of this approach is illustrated by a realistic design example.

    Abstract: Enabling lithium-ion batteries (LIBs) to operate in a wider temperature range, e.g., as low or high as possible or capable of both, is an urgent need and shared goal. Here we report, for the first time, a low-temperature electrolyte consisting of traditional ethylene carbonate, methyl acetate, butyronitrile solvents, and 1 M LiPF 6 salt, attributed to its very low freezing point ( T f = −126.3 °C) and high ion conductivity at extremely low temperatures (0.21 mS/cm at −100 °C), successfully extends the service temperature of a practical 9.6 Ah LIB down to −100 °C (49.6% capacity retention compared to that at room temperature), which is the lowest temperature reported for practical cells so far as we know, and is lower than the lowest natural temperature (−89.2 °C) recorded on earth. Meanwhile, the high-temperature performance of lithium-ion batteries is not affected. The capacity retention is 88.2% and 83.4% after 800 cycles at 25 °C and 45 °C, respectively. The progress also makes LIB a proper power supplier for space vehicles in astronautic explorations.

    Abstract: Acupuncture and moxibustion therapy, as a traditional medical treatment method of the motherland, is widely used in the treatment of mild cognitive dysfunction, with remarkable curative effect, and is increasingly recognized by the medical community. However, so far, there is no acupuncture prescription and acupoint usage rules for acupuncture treatment of mild cognitive impairment. Therefore, it is of great significance to collect, organize and data mining related data in order to summarize the relationship between acupuncture points and mild cognitive dysfunction, and to provide references for clinical treatment. This article standardizes the acupuncture points in the database. This paper uses Excel and SPS software to carry out frequency analysis, cluster analysis and association rules, and draws the rules of acupoints, meridians, positions, frequency of specific acupoints, clustering of acupoints and compatibility. In this paper, the number of cases in the treatment group and the control group, the main acupoints and matching points of the acupuncture prescription, the treatment methods, the efficacy evaluation indicators, and the total effective rate of the treatment group and the control group are extracted into the Excel table to form a mild cognition of acupuncture treatment Prescription database for dysfunction. This article studies the rules and characteristics of acupuncture points derived from data mining, takes the general rules and characteristics of clinical acupuncture and moxibustion treatment as a reference for clinical acupuncture and moxibustion, and verifies it with the results obtained. The experimental results show that in the analysis of association rules, taking Baihui and Shenting as examples, the support degree indicates that the probability that the two acupoints appear in the 126 heads at the same time is 51.83%, and the confidence and support for the occurrence of Baihui and Shenting are relatively high. High, it is considered to be a common compatible point pair for acupuncture treatment of mild cognitive dysfunction.

    Abstract: Background: The evaluation of treatment response to antidepressant therapy commonly depends on neuropsychologic assessments, as there are currently no suitable biomarkers. Previous research has identified a panel of increased proteins in patients with major depressive disorder (MDD), including antithrombin III (ATIII), as potential biomarkers of depression. Methods: A total of 90 MDD patients were recruited. Of these, 74 patients received occipital repetitive transcranial magnetic stimulation (rTMS) as individualized, standard, or sham treatment for 5 days, and underwent the complete procedure, including clinical assessments, blood collection, and protein measurement. Results: After treatment, ATIII was significantly decreased in both the individualized and standard groups (both p & lt; 0.001) relative to the sham group. In the individualized group, reduction in ATIII was associated with improvements in several neuropsychological assessments. Furthermore, ATIII at baseline in the standard group and after individualized rTMS showed good performance for evaluating or predicting the response to five-day treatment (AUC = 0.771, 95% CI, 0.571–0.971; AUC = 0.875, 95% CI, 0.714–1.000, respectively) and remission at follow-up (AUC = 0.736, 95% CI, 0.529–0.943; AUC = 0.828, 95% CI, 0.656–1.000, respectively). Lastly, both baseline ATIII and change in ATIII showed good predictive value for the 24-item Hamilton Depression Rating Scale at follow-up ( p = 0.024 and 0.023, respectively). Conclusion: Our study revealed a reduction in ATIII after occipital rTMS in MDD patients and a relationship between change in ATIII and therapeutic response. Taken together, these findings provide evidence for the potential of ATIII as a biomarker for the evaluation and prediction of antidepressive effects.

    Abstract: In extreme space environments with alternating and uneven temperature variations, the surface accuracy of cable-net antennas deteriorates significantly, thereby inducing a periodic failure or a significant deviation in the electrical performance. This is because of the lack of effective methods for controlling the surface shape during the service of the cable-net antenna. In this study, a method based on ‘two-way memory spring’ is proposed to actively control the surface of a cable-net antenna. Herein, first, an electro-thermo-mechanical model of the shape memory alloy (SMA) spring is deduced by combining the intrinsic model of the two-way shape memory effect and the resistance property of the SMA. Subsequently, a principle prototype is developed, and experiments related to active control are conducted to confirm the feasibility and effectiveness of the proposed method.

    Abstract: Background/Aims: The storage amount of liver glycogen could affect the liver fibrosis assessment made by MRI-based methods. However, it remained unclear whether glycogen amount could bias the estimation of liver fat content by proton density fat fraction. In this study, we aimed to investigate whether glycogen metabolism gene variants could contribute to the bias of PDFF by genetic association. Methods: We conducted an association study of the glycogen metabolism genes based on the PDFF data of 11,129 participants in the UK Biobank. The effect of the SNPs in these genes on non-alcoholic fatty liver disease was estimated by a meta-analysis of the available NAFLD case-control studies. Results: We identified significant associations of the SNPs near the genes encoding glycogen phosphorylase ( PYGM and PYGL ) and synthase ( GYS2 ) with PDFF (FDR-corrected p value & lt; 0.05). The genes encoding the regulatory proteins of glycogenolysis ( PHKB , CALM2/3 ), glucose transporter ( SLC2A1 ), and glucose kinase ( GCK ) were also associated with PDFF. The SNP rs5402 of SLC2A2 and rs547066 of PYGM were associated with NAFLD ( p & lt; 0.05) with others being insignificant. Except for the PYGM gene, the PDFF-associated SNPs showed no associations with NAFLD. In addition, the burden tests of rare variants in these genes were not significant after FDR correction. Conclusion: Liver glycogen metabolism genes associated with PDFF were not associated with NAFLD, which implicated a potential bias effect of glycogen storage on the quantification of liver fat content by PDFF.
