    Abstract This article is concerned with the path planning of mobile robots in dynamic environments. A new path planning strategy is proposed by integrating the improved ant colony optimization (ACO) and dynamic window approach (DWA) algorithms. An improved ACO is developed to produce a globally optimal path for mobile robots in static environments. Through improvements in the initialization of pheromones, heuristic function, and updating of pheromones, the improved ACO can lead to a shorter path with fewer turning points in fewer iterations. Based on the globally optimal path, a modified DWA is presented for the path planning of mobile robots in dynamic environments. By deleting the redundant nodes, optimizing the initial orientation, and improving the evaluation function, the modified DWA can result in a more efficient path for mobile robots to avoid moving obstacles. Some simulations are conducted in different environments, which confirm the effectiveness and superiority of the proposed path planning algorithms.

    Abstract Objective: Cynarin is a derivative of hydroxycinnamic acid presented in various medicinal plants, such as
    Methods and results: In this study, we investigated that cynarin alleviated clinical symptoms in animal models, including disease activity index (DAI) and histological damage. Furthermore, cynarin can attenuate colon inflammation through decreasing the proportion of neutrophils in peripheral blood, reducing the infiltration of neutrophils, and macrophages in colon tissue, inhibiting the release of pro-inflammatory cytokines and suppressing the expression of STAT3 and p65. In cellular inflammation models, cynarin inhibited the expression of M1 macrophage markers, such as TNF-α, IL-1β, and iNOS. Besides, cynarin suppressed the expression of STAT3 and p65 as well as the phosphorylation of STAT3, p65. Cynarin inhibited the polarization of RAW264.7 and J774A.1 cells toward M1 and alleviated LPS/IFN-γ-induced cellular inflammation.
    Conclusion: Considering these results, we conclude that cynarin mitigates experimental UC partially through inhibiting the STAT3/NF-кB signaling pathways and macrophage polarization toward M1. Accordingly, cynarin might be a potential and effective therapy for UC.

    Abstract In this paper, the chemical microstructure of coal samples is quantitatively analyzed experimentally before and after liquid nitrogen cold soaking, by using elemental analyzer, X-ray diffractometer, and Fourier infrared spectrometer, including the reverse side of chemical composition of elements, organic matter, and functional groups. It was found that with the increase of coal metamorphism, the contents of carbon, nitrogen, and sulfur elements gradually increase, while those of hydrogen and oxygen elements gradually decrease. In addition, as the degree of metamorphism increases, the graphitization phenomenon of coal becomes weaker, the interlayer spacing of aromatic rings (d

    Abstract Abstract Background High-intensity interval training (HIIT) has been shown to enhance cardiovascular health. However, there is a lack of research investigating the specific cardiovascular effects of different HIIT training modes. Therefore, this study aimed to compare the acute effects of cycling-type high intensity interval training (C-HIIT) and resistance-type high intensity interval training (R-HIIT) on arterial stiffness, cardiac autonomic modulation, and cardiac biomarkers in healthy young men. Methods This is a cross-over randomized trial. Eleven healthy active young men took part in both C-HIIT and R-HIIT. Cardio-ankle vascular index (CAVI), heart rate variability (HRV), and systolic blood pressure (SBP) were measured before, immediately and 30 min after the exercise in C-HIIT and R-HIIT. Meanwhile, blood samples for cardiac troponin-T (cTnT) and amino-terminal pro-B-type natriuretic peptide (NT-proBNP) were assessed using ELISA before, 5min and 35min after exercise. Results There was a significant time × group interaction effect (P = 0.019, η p 2 = 0.182) and time main effect for ⊿CAVI (P < 0.001, η p 2 = 0.729), and R-HIIT resulted in a more significant reduction in ⊿CAVI compared to C-HIIT (− 0.60 ± 0.30, P = 0.043, d = 0.924) immediately after exercise. There was a significant time main effect was observed for SBP (P = 0.001, η p 2 = 0.304). A significant time main effect for lnHF (P < 0.001, η p 2 = 0.782), lnRMSSD (P < 0.001, η p 2 = 0.693), and LF/HF (P = 0.001, η p 2 = 0.302) of HRV was observed. A significant time main effect was observed for cTnT (P = 0.023, η p 2 = 0.193) and NT-proBNP (P = 0.001, η p 2 = 0.334) of cardiac biomarkers. Conclusion R-HIIT and C-HIIT elicited similar acute responses in cardiac autonomic modulation and cardiac biomarkers. However, R-HIIT was more effective in reducing arterial stiffness in healthy young men. Furthermore, the increase in cardiac biomarkers induced by both C-HIIT and R-HIIT was reversible.

    Abstract In this paper, the chemical microstructure of coal samples is quantitatively analyzed experimentally before and after liquid nitrogen cold soaking, by using elemental analyzer, X-ray diffractometer, and Fourier infrared spectrometer, including the reverse side of chemical composition of elements, organic matter, and functional groups. It was found that with the increase of coal metamorphism, the contents of carbon, nitrogen, and sulfur elements gradually increase, while those of hydrogen and oxygen elements gradually decrease. In addition, as the degree of metamorphism increases, the graphitization phenomenon of coal becomes weaker, the interlayer spacing of aromatic rings (d₀₀₂) increases, the structure of coal crystal nucleus is loose, its order is weakened, the crystal volume becomes smaller, and the void structure unit increases. The FTIR spectra of each coal sample could be divided into four absorption bands, i.e., the aromatic structure, oxygen-containing functional group, aliphatic group, and hydroxyl absorption band. After cold soaking of liquid nitrogen, the peak intensity areas of aromatic and aliphatic structures decrease, while those of oxygenated functional groups and hydroxyl groups increase, and the values of A(C = O)/A(C-O) increase and those of A(CH₃)/A(CH₂) decrease, mainly due to the gradual decrease of methylene side chains and increase of methylene straight chains. The present results are helpful to further reveal the mechanism of adsorption-resolution deformation of coal body due to cold immersion of liquid nitrogen.
