Sugarcane trash, consisting mainly of dried leaves, tops and cans, is often burned in fields, posing serious risks to human health, contributing to environmental pollution, and depleting soil nutrients. Black soldier fly larvae (BSFL) offer a promising solution for organic waste management by converting it into insect proteins. This study aimed to develop a microbial fermentation method to utilize sugarcane waste as feed for BSFL and investigate underlying mechanisms. Our results revealed that all fermented groups exhibited enhanced growth and developmental performance, with the combination of Bacillus subtilis, Enterococcus faecalis, and Saccharomyces cerevisiae leading to the highest increases in larval body weight, survival rate, substrate conversion efficiency, and protein content compared to the unfermented group. Metagenomic analysis revealed a notable increase in the phylum Firmicutes, along with its beneficial strains such as Bacillus licheniformis, B. safensis, B. pumilus, Cytobacillus kochii, and Lysinibacillus fusiformis, in the gut of BSFL reared on fermented sugarcane waste, leading to improved gut homeostasis and reduced pathogenic loads. Additionally, the BSFL fed with fermented sugarcane waste exhibited high abundances of carbohydrate-active enzymes (CAZymes) involved in cellulose, hemicellulose, and starch degradation at both class and family levels. Transcriptome analysis further indicated the upregulation of key genes associated with key physiological processes, such as carbohydrate metabolism, chitin biosynthesis, and defense mechanisms. Collectively, these findings demonstrate the synergistic potential of microbial fermentation and BSFL for sustainable sugarcane waste management while advancing the understanding of host-microbe-diet interactions in insect-based bioconversion systems.

The description of particles with spin can be attained by using a spin density matrix in high energy reaction. In this paper we present a parametrization of the spin density matrix for spin-3/2 particles in the Cartesian form. Comparing the standard form which is given by the spherical tensor operator with the Cartesian form yields four equations for the spin polarizations. These four equations can be used to eliminate the dependent spin polarizations. We also present the probabilistic interpretations of these spin polarizations by defining the spin operator in the spherical coordinate frame. These results can be used in the cross section to calculate the hadron polarizations. To illustrate this, we calculate the inclusive electron-positron annihilation process in terms of spin polarizations. Copyright © 2019, The Authors. All rights reserved.

Based on the acoustoelastic theory, the ultrasonic nondestructive testing method of stress distribution in the thickness direction or bolt axial direction (which is called the Z axis after) is studied. The detection formula was deduced by combining the shear wave and the longitudinal wave, and the stress coefficient is replaced by the acoustoelasticity coefficient to reduce the impacts of the test principle, the uneven thickness and inaccurate stress coefficient. Then the software of ultrasonic testing stress in Z axis direction is compiled by combining interpolation with cross-correlation algorithm, and the detection system is constructed. Tensile tests are conducted with bolts of different specification and length. Error of tensile stress detection, compared with the calculation, is extremely subtle. When the stress increases to over 100MPa, the relative error is less than 5%. The experiment results show that this reliability evaluation method for stress in the direction of thickness is feasible. © 2018 IEEE.

A Cascade Failure Model with Topology Variation

A Cascade Failure Model with Topology Variation

Chinese Control Conference

作者： Hao Fan Ning Huang Guoyi Wen School of Reliability and Systems Engineering Beihang University Beijing Key Laboratory of Science & Technology on Reliability & Environmental Engineering Beihang University Beijing

The exsiting cascade failure models mostly focus on the network paralysis caused by the removal of the nodes or edges. However, in a transportation network, traffic accidents happened on edges create new nodes. In this paper, a model with topology variation is established by adopting the method of topology variation in biomolecular network. To establish the cascade failure model with network topology variation, we introduced a congestion coefficient into the user equilibrium distribution model. The proposed cascade failure model can be used to evaluate and quantify cascade failures caused by traffic accidents in a transportation network.

The data detected by the cosmic-ray imaging detector used to imaging the distribution of nuclear fuel cannot be transmitted outside the vessel. An ultrasonic through-wall communication system is designed to support the true-wireless monitoring in NPPs. This system could transmit data through the Steel Lining or the concrete wall of the containment wirelessly without cables and penetration, which could protect the leakproofness and integrity of the containment and enhance the safety of NPPs. With 40 kHz ultrasonic carrier waves, this system could communicate at 4.8kbits/s baud rate through over 10cm concrete wall, over 10cm steel liner and 10cm lead + 5cm steel combination wall. An application test has been finished on the 20:1 experiment containment to AP1000 in the Beijing key laboratory of Passive Safety technology for Nuclear Energy, this system could operate steadily with 0 error rate.

In this paper, the thermal analysis and structural analysis of MLCC are carried out by using the commercial finite element software ANSYS. By comparing the thermal-mechanical analysis results of the structural optimization models of different schemes, the optimal optimization scheme is found. The model calculated the time required for MLCC to reach temperature stability considering thermal convection and heat conduction, and obtained the thermal deformation and thermal stress distribution of MLCC element. Based on the analysis results of MLCC original model, the thermal analysis under different wave soldering temperatures was carried out. Based on the simulated transient results, the structure and materials of MLCC key components were optimized. The results provide a basis for the optimal design of MLCC.

25th International Conference on Vibroengineering

It is crucial to effectively and accurately diagnose fault of rotating machinery. However, high dimension characteristic of features, which are extracted from vibration signals of Rotating machinery, makes it difficult to recognize accurately fault mode. To resolve this problem, t-distributed stochastic neighbor embedding (t-SNE) is introduced to reduce the dimensionality of the feature vector in this paper. Therefore, the article proposes a method for fault diagnosis of Rotating machinery based on local characteristic decomposition-sample entropy (LCD-SampEn), t-SNE and random forest (RF). Firstly, original vibration signals of rotating machinery are decomposed to a number of ISCs by the LCD. Then, feature vector is obtained through calculating SampEn of each ISC. Subsequently, the t-SNE is used to reduce the dimension of the feature vectors. Finally, the reconstructed feature vectors are applied to the RF for implementing the classification of fault patterns. Two cases are studied based on the experimental data of bearing and hydraulic pump fault diagnosis, in which the proposed method can achieve 98.22 % and 98.75 % of diagnosis rate respectively. Compared with the pear methods, the proposed approach exhibits the best performance. The results validate the effectiveness and superiority of the present method. © JVE International Ltd.
