Brown rice(BR)is a traditional health food being rich in various active substances, which have effective preventive and therapeutic effects on many diseases. In this review, we systemically summarized the efficacy of BR on cardiovascular diseases(CVDs), hyperlipidemia, hypertension, diabetes, obesity, osteoporosis, neurodegenerative diseases, cancer, immune disorders, inflammation, anxiety, liver and stomach damage, etc. Underlying mechanisms have also been analyzed, which include regulating lipid synthesis and metabolism, improving insulin levels and increasing glucose metabolism, anti-oxidation, promoting the immune system, transcription and non-transcriptional regulation, blocking cell cycle, thereby improving disease symptoms and reducing its recurrence rate. Generally, BR has been almost disappeared in modern society, but it is promising to exploit the potential to become a functional food. Further research on the nutritional value, variety differences, storage problems, taste and molecular mechanism of BR will be conducive to help meticulously design clinical intervention trials and ultimately improve the treatment and prevention of various diseases.

Over the last decade, Augmented reality (AR) has witnessed a significant increase in popularity largely. Consequently, as a central component of these applications, large-scale 3D reconstruction has gained more and more attention. One of the promising solutions is using the camera and the Structure from Motion(SfM) method, especially with the advent of multi-camera devices. However, most of these methods are susceptible to failure in some high-traffic commercial street scenarios due to lots of moving objects and texture-free scenes. Besides, these methods treat each image as a separate source of information, which significantly degrades the performance of the multi-camera acquisition systems now commonly used. Hence, this paper presents a two-stage reconstruction pipeline to obtain an accurate large-scale 3D map in the central business district with multi-camera devices. In the first stage, we enhance the robustness of the incremental SfM method by using the pose prior obtained from the multi-camera visual-inertial system(VINS) and advance the accuracy of the reconstruction result in the second stage by performing the global optimization considering the multi-camera extrinsic constraints. Experiments show that our method yields more complete and accurate maps than its counterpart. © 2023 Technical Committee on control Theory, Chinese Association of Automation.

The simultaneous removal of methylene blue (MB) and Ca2+ by recyclable adsorbents based the scales derived from coal gasification system

Environmental science and Pollution Research 2024年第22期31卷 32519-32537页

作者： An, Bai-Hong Xu, Da-Mao Wang, Run-Ting Wen, Ye-Xuan Geng, Rui Wu, Jia-Yun Tang, Xian-Chun Chen, Hong-Bin State Key Laboratory of Pollution Control and Resource Reuse College of Environmental Science and Engineering Tongji University Shanghai200092 China National Engineering Research Center for Urban Pollution Control Tongji University Shanghai200092 China Department of Materials Science Fudan University Shanghai200433 China Sinopec Ningbo Engineering Co. LTD Ningbo315103 China

The transformation of solid wastes from industrial production into effective adsorbents could significantly contribute to wastewater treatment. In this study, after acidizing and burning soft scale (SS) from coal gasification system, two magnetic adsorbents (mag-ASS and mag-BASS) were prepared via the combination of magnetite with ultrasonic, respectively. The treatment effects of mag-ASS and mag-BASS were then investigated for simulated wastewater containing macromolecular organic matter [i.e., methylene blue (MB)] and Ca2+. The results indicated that the pseudo second order kinetic, Elovich, Freundlich, Langmuir and Temkin model could well describe the adsorption behavior of MB and Ca2+ onto mag-ASS and mag-BASS. The maximum adsorption capacities of mag-ASS for MB and mag-BASS for Ca2+ were 600.53 mg/g and 102.54 mg/g, respectively. Surprisingly, the adsorption abilities of mag-ASS for MB and mag-BASS for Ca2+ show significantly higher than the others. The adsorption mechanisms of MB mainly included electrostatic interaction, π-π conjugate interaction and cation exchange, while those of Ca2+ were mainly electrostatic interaction and cation exchange. The diffusion of MB and Ca2+ onto the magnetic adsorbents might be controlled by the combined effects of intraparticle and liquid film diffusion. There was no significant reduction in adsorption capacity after 8 cycles of adsorption and desorption, indicating that SS-based magnetic adsorbents had good recyclability and stability. Moreover, the removal efficiency of mag-BASS for total hardness and total organic carbon in real coal gasification gray water (CGGW) was 82.60 and 64.10%, respectively. The treatment of CGGW and the resource of wastes would significantly promote the reasonable disposal of coal gasification scales.
