At present, Rapid IO has been widely used in embedded platforms due to its high transmission efficiency and low transmission delay, making the software of the embedded platform a new speed. Windows system has the advantages of friendly interface, wide user base, easy maintenance and upgrade, etc., which has received extensive attention in the industry, but the real-time performance is poor and it is impossible to directly communicate with the embedded processor directly through Rapid IO, which makes it impossible to become a semi-physical simulation system. Therefore, the TSI721 driver development based on the RTX environment is designed. The internal structure of Rapid IO protocol, RTX real-time subsystem and Tsi721 switch chip is briefly described. Detailed description of the development framework and interface design of the Tsi721Pcie driver, the main process of RTX driver development. Experiments verify that PCIe and RTX drivers are stable, reliable, and capable of completing tasks in real time. © 2019 Association for Computing Machinery.

The rapid advancement of the photovoltaic (PV) industry has elevated the recycling and reuse of decommissioned PV modules to critical challenges, essential for tackling environmental concerns and achieving resource reutilization. To facilitate the efficient layering of PV modules and recovery of valuable materials, this study proposes a PV module degradation and recycling process utilizing supercritical n-butanol. A systematic evaluation was conducted to assess the effects of various factors on the dissolution ratio of PV modules, with an appropriate range of process parameters selected for optimization. A second-order regression model was developed to predict the dissolution ratio of the EVA film. Comparison of actual dissolution ratio with model predictions confirmed the high accuracy of the fitted model. Finally, characterization and elemental analysis of cells recovered from the supercritical process demonstrated the effectiveness of this recycling method, achieving more thorough degradation on the cell surfaces.

Case study on the combined use of surface seawater injection and depressurization for sustainable natural gas hydrate extraction

JOURNAL OF CLEANER PRODUCTION 2025年 494卷

In response to the issue of inefficient extraction of natural gas hydrates due to a lack of heat supplementation during long-term production, a combined extraction method integrating surface seawater injection and depressurization has been proposed. Under the premise that the surface seawater injection pipeline possesses certain thermal insulation properties, this method can sustainably harness solar energy to replenish the thermal energy of gas hydrate reservoirs. Numerical simulations based on a validated three-dimensional heterogeneous model from the 2013 Nankai Trough pilot production in Japan demonstrate that this method significantly enhances hydrate extraction efficiency compared to depressurization alone. The results show that, over a 500-day production scenario, methane recovery efficiency can be enhanced by up to 150%. The study reveals that only an appropriate injection temperature can effectively improve the efficiency of hydrate exploitation. Compared to the depressurization-only method, this extraction approach increases the temperature driving force (TDF) near the injection well improved by up to 12 K. However, higher injection rates suppress depressurization effects, requiring a balance between injection temperature and rate. The proposed approach also facilitates more uniform reservoir deformation, reducing localized subsidence risks. These findings suggest that the combined surface seawater injection and depressurization method provides an effective and environmentally friendly solution for sustainable hydrate exploitation.

Satellite prediction of very high frequency (VHF) Data Exchange (VDE)-Terrestrial (VDE-TER) ship-to-ship Self-Organized Networks (SON) service traffic information is crucial for wireless resource allocation of VHF Data Exchange System (VDES). Due to the VDE-TER, channel load observed by the satellite changes rapidly and the historical information cached on the satellite is limited;the prediction of VDE-TER service traffic is difficult. This paper proposes a multilayer bidirectional long short-term memory (LSTM) neural network model (MLB-LSTM), which controls the amount of forgetting of historical information and the amount of memory of current information through the LSTM unit, so that the model can better learn the nonlinear changes of service traffic. The bidirectional LSTM module combines forward and backward time series data, reducing the amount of data required for prediction and enhancing the prediction accuracy of the model. Numerical results show that the proposed prediction model significantly outperforms traditional methods and is able to adapt to rapidly changing VDE-TER data.

Biomimetic Dendrimer-Peptide Conjugates for Early Multi-Target Therapy of Alzheimer's Disease by Inflammatory Microenvironment Modulation

Current therapeutic strategies for Alzheimer's disease (AD) treatments mainly focus on beta-amyloid (A beta) targeting. However, such therapeutic strategies have limited clinical outcomes due to the chronic and irreversible impairment of the nervous system in the late stage of AD. Recently, inflammatory responses, manifested in oxidative stress and glial cell activation, have been reported as hallmarks in the early stages of AD. Based on the crosstalk between inflammatory response and brain cells, a reactive oxygen species (ROS)-responsive dendrimer-peptide conjugate (APBP) is devised to target the AD microenvironment and inhibit inflammatory responses at an early stage. With the modification of the targeting peptide, this nanoconjugate can efficiently deliver peptides to the infected regions and restore the antioxidant ability of neurons by activating the nuclear factor (erythroid-derived 2)-like 2 signaling pathway. Moreover, this multi-target strategy exhibits a synergistic function of ROS scavenging, promoting A beta phagocytosis, and normalizing the glial cell phenotype. As a result, the nanoconjugate can reduce ROS level, decrease A beta burden, alleviate glial cell activation, and eventually enhance cognitive functions in APPswe/PSEN1dE9 model mice. These results indicate that APBP can be a promising candidate for the multi-target treatment of AD.

The temperature fluctuation of a cesium oven has a significant impact on the performance of time-keeping cesium beam frequency standards. We have designed a circuit system for the precise temperature control of the cesium oven used in it. The use of a 24-bit analog-to-digital converter ensures a temperature measurement resolution more than 0.5 mK within the working range. The digital PID algorithm guarantees the accuracy of error signal computation, and a 16-bit digital-to-analog converter improves the resolution of the control current adjustment. Ultimately, we achieved the goal of keeping the temperature fluctuation of the cesium oven to less than 4 mK within a working range of 120 degrees C. The results indicate that the circuit system effectively ensures the performance of the cesium beam frequency standard.
