Hawthorn (CFS) has commonly been applied as an important traditional Chinese medicine and food for thousands of years. The raw material of CFS is commonly processed by stir-frying to obtain yellow (CFY), dark brown (CFD), and carbon dark (CFC) colored products, which are used for different clinical uses. In this study, an intelligent sensory system (ISS) was used to obtain the color, gas, and flavor samples data, which were further employed to develop a novel and accurate method for the identification of CFS and its processed products using principal component analysis. Moreover, this research developed a model of an artificial neural network, which could be used to predict the total organic acid, total flavonoids, citric acid, hyperin, and 5-hydroxymethyl furfural via determination of the color, odor, and taste of a sample. In conclusion, the ISS and the artificial neural network are useful tools for rapid, accurate, and effective discrimination of CFS and its processed products.

In order to develop a lightweight cement based composite with dual-function of EM wave absorption and thermal insulation, sandwich structure was designed to achieve excellent EM absorption capacity, and expanded perlite and carbon black were used as lightweight aggregates and EM absorbent, respectively. The EM absorption properties were studied by arching reflected method, and the results indicate that the sandwich structure design can obviously enhance the EM absorption capacity of cement composites. The sandwich structured composites exhibit better EM absorption properties than the traditional gradient multi-layer structured composites. The reflection loss of three-layer and four-layer sandwich structured composites can be less than -10 dB and -15 dB in the whole X-band. The thermal conductivity test results shows that the developed cement composites possess thermal insulation function.

This study provides a novel broadband gypsum composite for electromagnetic (EM) radiation protection by the design of 3D circular periodic structure, and using carbon black (CB) as absorbent. The EM absorption performance was investigated by arch reflecting method in 2–18 GHz, and the obtained results indicate that the proposed gypsum absorber exhibits more than 90% absorption of EM radiation in the frequency range of 2–18 GHz. The EM wave absorption can be obviously affected by the variation of CB content, periodic cylinder height and diameter. The optimum CB content is 2 wt%, simultaneously, the absorption peak can be promoted to shift to lower frequency by the increase of periodic cylinder height and the increase of periodic cylinder diameter is beneficial to widen the effective bandwidth. The λ/4 interference of reflected waves, energy dissipation of CB particles, and multi-reflection, resonance, edge diffractions, and impedance matching caused by 3D periodic structural design work synergistically to achieve the high EM absorption efficiency and wide frequency band. It is expected that the proposed 3D circular periodic structured gypsum absorber has great potential in indoor EM radiation prevent.

PURPOSE This study uses the extended model of goal-oriented behavior to predict and test the behavioral intentions of Chinese public Taekwondo consumers. Based on the original MGB, the study adds five variables related to Taekwondo consumption characteristic to investigate the influencing factors of general Taekwondo consumers' consumption decision-making process. METHOD This study conducts an online survey of 417 students studying in the Chinese Taekwondo Gymnasium and uses IBM SPSS statistical software 26.0 and AMOS 23.0 to analyze the data. Then, the data analysis is divided into two stages. In the first stage, confirmatory factor analysis (CFA) is used to test the reliability and validity of the scale. In the second stage, a structural equation modeling (SEM) analysis is employed to test the proposed hypotheses. RESULT The CFA test shows that the data and the model have a good fit, and the model has high combined reliability and convergence validity. And through the modification of the model, a SEM is established. CONCLUSION The results show that desire has the most significant impact on consumers' behavioral preference, followed by past satisfaction and Taekwondo coach image. Past satisfaction significantly affects desire, which in turn affects consumersʼ behavioral preference. The two constructs of Taekwondo cognition and perspective form a positive and significant relationship. In addition, perspective has developed a considerable influence relationship with past satisfaction and Taekwondo coach image, which influences behavior preferences. Expected emotions significantly affect past satisfaction, which indirectly affects desire and consumer behavioral intentions.

Glomerular mesangial cell (GMC) proliferation is a histopathological alteration in human mesangioproliferative glomerulonephritis (MsPGN) or in animal models of MsPGN, e.g., the rat Thy‐1 nephritis (Thy-1N) model. Although sublytic C5b-9 assembly on the GMC membrane can trigger cell proliferation, the mechanisms are still undefined. We found that sublytic C5b-9-induced rat GMC proliferation was driven by extracellular signal‐regulated kinase 1/2 (ERK1/2), sry-related HMG-box 9 (SOX9), and Cyclin D1. Here, ERK1/2 phosphorylation was a result of the calcium influx-PKC-α-Raf-MEK1/2 axis activated by sublytic C5b-9, and Cyclin D1 gene transcription was enhanced by ERK1/2-dependent SOX9 binding to the Cyclin D1 promoter (−582 to −238 nt). In addition, ERK1/2 not only interacted with SOX9 in the cell nucleus to mediate its phosphorylation at serine residues 64 (a new site identified by mass spectrometry) and 181 (a known site), but also indirectly induced SOX9 acetylation by elevating the expression of general control non-repressed protein 5 (GCN5), which together resulted in Cyclin D1 synthesis and GMC proliferation. Moreover, our in vivo experiments confirmed that silencing these genes ameliorated the lesions of Thy‐1N rats and reduced SOX9 phosphorylation, acetylation and Cyclin D1 expression. Furthermore, the renal tissue sections of MsPGN patients also showed higher phosphorylation or expression of ERK1/2, SOX9, and Cyclin D1. In summary, these findings suggest that sublytic C5b-9-induced GMC proliferation in rat Thy-1N requires SOX9 phosphorylation and acetylation via enhanced Cyclin D1 gene transcription, which may provide a new insight into human MsPGN pathogenesis.

A practical single photon source for fiber-based quantum information processing is still lacking. As a possible 1.55-µm quantum-dot single photon source, an InGaAsP/InP-air-aperture micropillar cavity is investigated in terms of fabrication tolerance. By properly modeling the processing uncertainty in layer thickness, layer diameter, surface roughness and the cavity shape distortion, the fabrication imperfection effects on the cavity quality are simulated using a finite-difference time-domain method. It turns out that, the cavity quality is not significantly changing with the processing precision, indicating the robustness against the imperfection of the fabrication processing. Under thickness error of ±2 nm, diameter uncertainty of ±2%, surface roughness of ±2.5 nm, and sidewall inclination of 0.5°, which are all readily available in current material and device fabrication techniques, the cavity quality remains good enough to form highly efficient and coherent 1.55-µm single photon sources. It is thus implied that a quantum dot contained InGaAsP/InP-air-aperture micropillar cavity is prospectively a practical candidate for single photon sources applied in a fiber-based quantum information network.

Particle shape influence the bearing capacity of calcareous sand foundations in island reef engineering. An improved Computer Image Analysis method that combined with mathematical statistics was proposed to categorize and sort different shapes of calcareous sand particles within the size range of 5 – 10 mm. Three single-shape calcareous sand specimens (granular ᅠ ᅠshape, dendritic shape, long strip shape) were obtained. A new self-developed vibration device was used measuring the maximum density of calcareous, the shape and content as the variables in the orthogonal test. On this basis, the lateral compression tests were carried out to assess the influence of particle shape on the density, compressive performance of calcareous sand. Test results showed that better discriminability was achieved by taking mean flatness (EL/B) as the quantification parameter of the particle shapes. The average flatness EL/B of specimens is approximately normally distributed in the statistical results. The shape and content of sand particles had an obvious influence on the density of calcareous sand. The compressive properties of calcareous sands with different particle shapes have obvious differences. After loaded, the particle size distribution of specimen improved, the average flatness EL/B of the granular-shaped specimens increased, while that of the dendritic-shaped and the long-strip-shaped specimens decreased, the average flatness EL/B of the specimens tended to be uniform. The relative fracture rate Br and the load value Pmax satisfied the exponential function fitting relationship. Therefore, it can be argued that particle shape should be taken into consideration when optimizing the foundation design in island reef engineering to achieve better compressive performance of the foundation.
