In the context of the dual-carbon goal, improving the level of scientific and technological innovation of modern carbon emissions and achieving comprehensive green development are not only one of the trends and important reform directions of today’s world development, but also the core content of achieving sustainable development. Taking the power industry as an important breakthrough, this paper uses blockchain technology and privacy computing technology to integrate data from the government, power grid, taxation and banks, and proposes a blockchain-based privacy computing algorithm for carbon emission scores to create an execution environment for trusted sharing of carbon emission data, expand channels for carbon emission data collection, and give full play to the value of big data on carbon emissions. Promote the realization of dual carbon goals as soon as possible.

In view of the limitations of modulated flooding technology in low permeability high temperature reservoirs, the water/oil emulsion with the effect of expanding sweep volume and its influence on the effect of modulated flooding were studied. Under the condition of high water content (80% water content), the dispersion system formed by emulsifier 55# and crude oil is mainly water/oil emulsion. At the same time, the influence of surfactant type, water content, temperature and other factors on the formation of water/oil emulsion system was investigated, and the influence of emulsion properties on the effect of displacement was analyzed. The low permeability core experiment shows that the emulsifier with the effect of expanding sweep volume can improve the oil recovery by 17.93% on the basis of water flooding, which is obviously higher than that of polymer flooding. At the same time, emulsifier has good temperature resistance, which is of great significance for enhancing oil recovery in high temperature and low permeability water drive reservoirs.

The objective of this research was to evaluate the influence of high-voltage electrostatic field (HVEF) on the freezing of human epidermal melanocytes (HEM) with respect to the degree of cell deformation, survival and proliferation rate after cell resuscitation. As a result, the degree of supercooling is increased by enhancing the strength of the static electric field in the range of 15 kV/m, and the maximum supercooling degree is 7.83±0.05 °C at 15 kV/m. By contrast, the morphology of the electric field assisted freezing cell after resuscitation was significantly improved, and the best electric field strength for cryopreservation is 15 kV/m. The survival rate of human epidermal melanocytes recovered was 88.03%, which was higher than that of the control group. The proliferation rate at 24, 48 and 72 hours are 17%, 28% and 25%, respectively, which are higher than that of the control cells. These findings demonstrate that the freezing HVEF can protect the cell physiological activity, and reduce the freezing damage. Therefore, the optimal HVEF cryopreservation technology be of great significance for the research of tissue engineering in repairing wounds, infections, and promote the development of food, medicine and other fields.

This paper analyzes the status quo of financial supervision in the Northeast Asia Free Trade Zone and finds that the coordination and cooperation of financial supervision in the Northeast Asia Free Trade Zone is in the exploratory stage. There is room for cooperation in financial supervision, which creates conditions for the implementation of the "supervisory sandbox" in the region. It demonstrates the significance of introducing the “regulatory sandbox” model in the Northeast Asia Free Trade Zone from three aspects: balancing financial innovation and supervision, promoting the realization of inclusive finance, and improving the global shared supervision database. Build a relatively complete "supervision sandbox" operation process design. Finally, the countermeasures and suggestions for the introduction of the "supervisory sandbox" model in the Northeast Asia Free Trade Zone are proposed.

The combination of network pharmacological methods and experimental verification has revealed the underlying molecular mechanism of Corilagin in the treatment of breast cancer. In this study, we used Swiss Target Prediction database network to predict the possible candidate targets and pathways of Coilagin, and collect breast cancer targets and pathways of CooLGeN. The result of network pharmacological screen indicated that Bcl is a key pathway for Corilagin in the treatment of breast cancer. The CCK-8 experiment also proved that Corilagin could inhibit the proliferation of MCF-7 cells. Western Blot was used for the validation of network pharmacological results, which showed that Corilagin could increase the apoptosis rates (Bcl-2/Bax) of MCF-7 cells, and up-regulates the apoptotic protein Caspase-3 and changes the Bcl-2 family proteins expression in MCF-7 cells. All results suggest that Corilagin has the potential therapeutic effects on breast cancer, and may be useful for adjuvant chemotherapy.

Reheating experiments and semisolid compression tests were conducted on two hot-extruded magnesium-rare earth (Mg-RE) alloys, Mg-8.20Gd-4.48Y-0.36Zr-3.34Zn and Mg-3.75Gd-5.15Y-0.75Zr-3.05Zn by using a multistage hot compression test machine. Dissolution of eutectic compounds, growth of grains, and partial melting took place during the reheating of these Mg-RE alloys and resulted in spherical semisolid slurries at certain temperatures (580 °C for Mg–8.20Gd–4.48Y–3.34Zn–0.36Zr, 560 °C for Mg-3.75Gd-5.15Y-0.75Zr-3.05Zn). Owing to the different alloying element contents of these two Mg-RE alloys, eutectic compounds with different morphologies were found inside them after reheating and rapid cooling processes. The forming characteristics of these two Mg-RE alloys in semisolid state were discussed based on the results of compression tests.

Optical display and measurement of transverse jet flow field under supersonic inflow is performed with continuous xenon lamp color schlieren, strobo light color schlieren and strobo light monochrome schlieren. Characteristic of fuel transverse jet in scramjet combustion chamber is studied. Results indicate that wave structure can be displayed through images obtained from long time exposure of schlieren, exposure time in dozens of nanoseconds is suitable for the display of turbulent structure, and comparing with color schlieren, amounts of information obtained from monochrome schlieren are few, whose sensitivity is much lower, either.

Hydraulic Engine Mounts (HEM) are important vibration isolation components with compound structure in the vehicle powertrain mounting system. They have the characteristic that large damping and high dynamic stiffness in the high frequency region, and small damping and low dynamic stiffness in the low frequency region, which can meet the requirements of the vehicle powertrain mounting system better. The method to identify the lumped parameters of the HEM is not only the necessary work for the analysis and calculation in dynamic performance and can also provide the theory for the performance optimization and structure optimization of product in the future. The parameter identification method based on coupled fluid-structure interaction (FSI) and finite element analysis (FEA) was established in this study to identify the equivalent piston area of the rubber spring, the volume stiffness of the upper chamber, as well as the inertia coefficient and damping coefficient of the liquid through the inertia track. The simulated dynamic characteristic curves of the HEM with the parameters identified are in accordance with the measured dynamic characteristic curves well.

Complex Event Processing (CEP) has become the key part of Internet of Things (IoT). Proactive CEP can predict future system states and execute some actions to avoid unwanted states which brings new hope to intelligent transportation control. In this paper, we propose a proactive CEP architecture and method for intelligent transportation control. Based on basic CEP technology and predictive analytic technology, a networked distributed Markov decision processes model with predicting states is proposed as sequential decision model. A Q-learning method is proposed for this model. The experimental evaluations show that this method works well when used to control congestion in in intelligent transportation systems.
