In order to reduce the repeated work intensity of drilling personnel and the risks faced by high-risk environments during oilfield exploitation, an intelligent manipulator is introduced into the drilling platform, and a dynamic target tracking control method of the manipulator based on deep reinforcement learning is proposed in this paper. In this paper The digital twin of the manipulator is constructed in the virtual drilling simulation environment, and multi-agent parallel training is carried out using the machine learning agents(ML-Agents) framework and proximal policy optimization(PPO) algorithm. The ideal training algorithm model is deployed to the virtual manipulator on the virtual drilling platform, and the virtual and real manipulator can track the dynamic target synchronously through serial communication. The experimental results indicate that synchronous tracking of dynamic targets with virtual and real robotic arms is feasible and accurate, providing a new approach for the digital twin application in the oil and gas industry.

[Objective] Globally, biobanks have become an essential tool for the protection and development of human genetic resources, and their development has played a very pivotal role in promoting basic research in life sciences and clinical diagnosis and treatment of major diseases. High-quality and standardized biobanks have become essential for basic research, translational clinical medicine research, and the implementation of precision medicine strategies. Recently, China has established some national or regional alliance-level biobanks; however, the issue of sharing mechanisms has always been a long-term factor restricting the full utilization of biological resources. There are a few examples of colleges and universities coordinating resources to promote the construction of school-level biobanks. [Methods] Herein, the focus is on constructing biobanks in medical colleges and universities in China, analyzing the difficulties and bottlenecks in sharing, and corresponding optimization policy references are proposed. The research methods employed are literature review, typical case analysis, survey questionnaire, and in-depth interviews, among others, to conduct multichannel and all-around research on the problem. [Results] Based on the literature survey, this paper summarizes the problems hindering biobank sharing into internal construction systems, external institutional management, and ethical issues, such as imperfect sample quality standardization and information access, informed consent, benefit sharing, and other specific issues. Through questionnaires, semi-structured interviews, and in-depth interviews, the results reveal that insufficient willingness to share, incomplete information disclosure, unclear benefit-sharing mechanism, lack of standardization of sample and information quality, and ethical concerns are the prominent problems hindering sharing. The relatively successful mechanism of the international and domestic representative biobanks in promoting sharing includes the formulation and implementation of unified biobank construction standards and norms, establishment of public and open information platforms, standardization of sharing rules and processes, benefit-sharing and distribution mechanism, and full implementation of scientific and reasonable ethical principles. [Conclusion] By referring to international and domestic successful cases while considering the advantages and foundations of medical colleges and universities, this paper proposes the following suggestions for biobank construction in medical colleges and universities. First, it is crucial to strengthen the top-level design and to create a "centralized and disaggregated" biological sample storage platform and network-sharing platform. Second, it is necessary to continuously strengthen the scientific construction of biological sample banks, promote the standardization of biological sample bank technology, boost the strength of professional management teams, and pay great attention to the disciplinary construction of biobanks. Third, strengthening the construction of the ethical governance system and ensuring reasonable informed consent and data security are important measures to promote effective data sharing while ensuring data privacy. Last, drawing on agreements signed by both parties for sample and data sharing, it is essential to establish the life cycle of research result data, constantly improve the sharing management mechanism, and innovate the benefit-sharing model.

[Objective] With increasing scientific research activities in university laboratories, the laboratory safety management system must be urgently optimized to address various laboratory accidents. Owing to the complexity of risk factors and difficulty in detecting safety hazards in university laboratories, analyzing factors influencing laboratory accidents plays a crucial role in preventing accidents. Based on the fuzzy-set qualitative comparative analysis (fsQCA) method, this study examines the effects of different condition configurations on laboratory accidents to explore the complex causal relationship between laboratory accidents and various factors. [Methods] First, based on the "human-machine-environment-management," a safety management system is constructed to analyze the factors influencing university laboratory accidents, and six causal conditions are extracted from the management system to investigate the condition configuration of the accident. Second, data regarding 30 typical accidents in Chinese universities are collected. According to the collected accident data, fuzzy assignment is attributed to the condition and result variables of each accident. Finally, the collected laboratory case data are analyzed using the fsQCA3.0 software, and the analysis results are processed according to the fsQCA handling method. Moreover, six configuration types affecting the severity of laboratory accident consequences are obtained. [Results] The results of the study show the following: management condition deficiencies or instrument and equipment failures are the core conditions affecting the occurrence of accidents, and unsafe people's behavior and accident handling often appear as the marginal conditions of accidents. The following rules were established based on the configuration analysis results: the lack of management conditions may not be the sole factor leading to accidents, but as a core condition, it will considerably impact the consequences of accidents; equipment accidents have complex path combinations; and human factors are typically present as marginal conditions in configuration, combined with other factors to form the causative path of laboratory accidents. Lastly, suggestions on laboratory safety management are proposed according to the rules displayed by configuration types. [Conclusions] Through the configuration analysis of accidents in university laboratories using the fsQCA method, six configuration types of accidents are obtained, three rules are summarized, and some suggestions for laboratory safety management are provided in this paper. This paper tries to deduce the causal relationship of multiple and concurrent laboratory accidents in Chinese universities from the configuration perspective. In addition, the proposed method introduces a new causal explanation mechanism for the occurrence of laboratory accidents and a new perspective for laboratory safety management.

[Objective] The rapid development of the intelligent transportation industry brings new opportunities and challenges for talent cultivation. The traditional cultivation system and teaching platforms for transportation majors face the following problems: 1) The cultivation modes of talents are not suitable for the rapid development of the industry. 2) The teaching methods are not coordinated with the development of industrial technologies. 3) The construction of a practical teaching platform is not synchronized with industrial development. 4) There is no sustainable and effective cooperation mechanism in the integration of industry and education. To solve the above problems, a teaching reform method based on the digital twin is proposed in this paper. [Methods] First, this paper analyzed the demand for transportation innovation talents and the significance of technological innovation capabilities, interdisciplinary comprehensive capabilities, and industry foresight capabilities. Meanwhile, a double-closed-loop innovative talent cultivation system of the integration of industry and education was established. One closed loop was theoretical teaching and professional skills practice, and the other closed loop was industrial demand and school supply. Second, a transportation digital twin method was proposed based on the five-dimensional model of the digital twin. The five dimensions of physical space, cyberspace, service system, digital twin data, and connection were deeply integrated with traffic scenarios. Based on the transportation digital twin method, this paper combined hardware (e.g., intelligent roadside devices, driving simulators, and miniature intelligent vehicles) with software (e.g., PreScan, Matlab, and PyCharm) to build the transportation digital twin experimental platform. The platform comprised three parts: the real traffic road, the cyberspace, and the semiphysical traffic simulation scene. Using this platform, real field tests can be replaced by digital twin experiments in the laboratory. Third, a typical experimental example of autonomous driving was selected to demonstrate the operating steps, including data collection and preprocessing, data conversion and traffic scenario construction, and autonomous driving algorithm development. Finally, six indexes were selected to evaluate the transportation digital twin teaching reform method, including learning attitude, cognition of majors, practical participation, course satisfaction, academic performance, and science and technology competition. [Results] The final evaluation results showed the following: 1) The proposed method can meet the learning needs of students, allow students to have a deep understanding of the practical applications of transportation professional courses, and improve their learning attitudes and cognition of majors. 2) Cyber space can provide students with repeated practice opportunities, effectively stimulating their enthusiasm for innovation and creativity, thereby improving their practical participation and course satisfaction. 3) There is a positive effect in promoting students' class performance, experimental results, and exam results, among others. This plays an important role in science and technology competitions. [Conclusions] The proposed teaching reform method based on the digital twin solved the problems existing in traditional transportation talent training systems and teaching platforms, which is of great significance for the cultivation of innovative talents of transportation majors.

[Objective] Epoxy asphalt mixtures are primarily used in pavements of long-span steel bridge decks. The heavy load traffic and orthotropic structural characteristics of steel bridge decks require epoxy asphalt mixtures with high deformation performance, material strength, and fatigue performance. The issues encountered with epoxy asphalt mixtures include ecracking and fatigue damage. Due to the high hardness and strength of epoxy asphalt mixtures, when the steel bridge deck deforms under sea wind loads, the internal stress of the material cannot be fully transmitted. Over time, microcracks can develop within the materialunder heavy traffic and vehicle loads. This results indeclined durability and causes cracks, pits, and other deformations, leading to functional impairment of the pavement layer. Therefore, we propose incorporating fibers to enhance the cooperative deformation capacity and service life of epoxy asphalt mixtures. [Methods] In this paper, the epoxy asphalt mixture was reinforced to satisfy the requirements of anticracking, antifatigue,etc., and the reinforcing effects of different fibers (basalt fiber, glass fiber, and polyester fiber) on the epoxy asphalt mixture were studied. First, tensile tests were performed on epoxy asphalt to determine its construction temperature and elongation at break. Using the Marshall test, the mixture design of EA-10 epoxy asphalt mixtures with basalt, glass, and polyester fibers and without fiber was conducted to measure the mineral composition and optimal oil--stone ratio of the four EA-10 epoxy asphalt mixtures. The research findings revealed that the retention time and tensile strength of epoxy asphalt satisfy the engineering requirements, and the optimal oil--stone ratios of the epoxy asphalt mixture without fiber and with basalt, glass, and polyester fibers are 6.5%, 6.7%, 6.6%, and 6.8%, respectively. Second, the road performance of the four EA-10 epoxy asphalt mixtures was examined by rutting, low-temperature small beam, immersed Marshall, and freeze--thaw splitting tests. Compared with the mixture without fibers, the fibers improved high-temperature rutting and low-temperature crack resistance, and their water stability performance was also improved to a certain extent. This shows that the fibers can improve the road performance of the mixture and that the basalt fiber has the best improvement effect. Finally, the toughening effects of the four EA-10 epoxy asphalt mixtures were exploredby impact testing. [Results] The results indicated that the impact toughness at -10 °C is significantly lower than that at 15 °C. At the same time, doping fibers can improve the impact toughness of the mixture, with the impact toughness of basalt fiber being optimal. 1 The hot-mixed epoxy asphalt was subjected to viscosity tests at different temperatures (140, 150, 160, 170, 180 °C) and elongation at break tests, which showed that the construction temperature of epoxy asphalt mixtures is optimal for construction temperatures of 160-170 °C, and the construction retention time was approximately 2 h. 2 The results of the low-temperature beam bending test to study the anticracking performance of the four EA-10 epoxy asphalt mixtures showed that fiber doping can significantly enhance the anticracking performance of epoxy asphalt mixtures, and basalt fiber-doped mixtures displayed the best anticracking effect. 3 The impact test demonstrated that the impact toughness of the fiber epoxy asphalt mixture at 15 °C is better than at -10 °C. [Conclusions] This paper provides a scientific basis for guiding the application of fibers in epoxy asphalt mixtures and a reference for researching fiber toughening technologies of epoxy asphalt mixtures.

[Objective] This paper focuses on the development of a bidirectional consolidated soil sample-making apparatus. The aim is to compare samples made by this apparatus with those created using compaction and static pressure methods and to analyze and verify the feasibility of the bidirectional properties. [Methods] In this paper, three types of test equipment were used to prepare consolidated soil samples of specified age. Several comparative tests were conducted, such as the unconfined compressive strength (UCS) test, the industrial electron microscopy test, the scanning electron microscopy test, and the mercury-in-pressure porosimetry test. These tests helped analyze and verify the feasibility of the bidirectional consolidated soil sample maker. They also enabled us to study the macro/fine/micro characteristics of the samples produced by the three test equipment from various angles, such as UCS and its destructive form, apparent porosity of the sample, microscopic porosity and filling of the curing product, microscopic pore volume, and pore size distribution. [Results] The results show that in terms of macro UCS of consolidated soil samples, the bidirectional sample has the highest UCS, followed by the static pressure sample and then the compaction sample. In terms of sample formation and destruction form, the bidirectional sample is uniform in color and has a stable destruction form (all are shear destruction). The static pressure sample is denser at the top and looser at the bottom, with destruction mostly in the weaker and lower parts. The compaction sample, however, shows distinct layering with varying shades and multiple forms of damage. Thus, the uniformity of the bidirectional sample is superior to that of the compacted and static compaction samples. Upon fine analysis, we found that compared with the static compaction sample (which has an apparent porosity that gradually increases from top to bottom) and the compaction sample (where the apparent porosity gradually decreases from top to bottom), the bidirectional sample has the smallest and most uniformly distributed apparent porosity. At the microscopic level, the bidirectional sample has the highest amount of curing products that can effectively fill the pores, making its internal microstructure the densest. It also has the least amount of mercury intake and is dominated by interparticle pores with smaller diameters. This is followed by the static pressure sample, while the compaction sample has the least amount of curing products, larger pores, the highest amount of mercury intake, and pores mainly distributed in the interparticle pores with larger diameters and the intragranular pores. [Conclusions] Therefore, the multiscale comparative study shows that the self-developed bidirectional sample-making instrument is better than that of the static pressure instrument outperforms both the static pressure and the three-segment mold (or double membrane) in terms of sample making. Not only does it deliver superior results, but it also exhibits a smaller margin of errors in tests. Consequently, this makes it a viable option for widespread adoption and application in geotechnical tests. [ABSTRACT FROM AUTHOR]

[Objective] Carbon dioxide (CO2) displacement and storage are the most viable technologies for achieving carbon neutralization and enhancing low-permeability reservoir recovery. The current research focused on the evaluation of CO2 storage capacity and mechanism under different geological conditions but ignored the problem of CO2 storage time being too long. When CO2 was injected into the stratum for geological burial, it mainly existed in the form of geological structure burial in the initial stage of injection (within several decades), and the safety was relatively low. In the middle stage of injection (within 100 years), it changed from geological structure burial to bound storage and gradually to dissolved storage, and the safety was relatively good at this time. In the later stage of injection (thousands of years), the storage forms were mainly dissolved storage and mineralized storage, and the safety was the highest. Therefore, through laboratory experiments, studying how to improve CO2 mineralization and storage speed and shorten the CO2 storage time using chemical agents is of great significance. [Methods] Based on the actual CO2 storage technology in reservoirs, a CO2 storage experimental device under formation temperature and pressure conditions was independently built, and multimedia-assisted CO2 storage experimental research was conducted. The precipitation of potassium carbonate through the utilization of the ethanol + KOH solution system enabled CO2 capture and carbonization. The reaction process in the solution system was affected by the ethanol concentration, resulting in different CO2 carbonization amounts with the change in the ethanol concentration. Simultaneously, the precipitation-generated potassium-based acid salt could undergo a reaction with water to facilitate ethanol regeneration. This paper utilized experimental methods to investigate the CO2 capture efficiency of the ethanol + KOH system, real-time monitoring of ethanol content in the solution, and identification of the optimal ethanol concentration for the formation temperature. The solution was supplemented with KOH, followed by the utilization of regenerated ethanol from the solution's carbonization reaction for subsequent carbonization, enabling the determination of the maximum CO2 capture capacity of the ethanol + KOH system. The CO2 burial experiment was conducted using a high-temperature and high-pressure core displacement device after injecting the ethanol + KOH solution. The characteristics of CO2 mineralization under different permeability/porosity conditions were discussed. [Results] The research results indicated that the 96% ethanol + 3-g KOH solution demonstrated effective CO2 capture, resulting in an average precipitation of 4.56 g per capture. Simultaneously, following the saturation of the core with the 96% ethanol + 3-g KOH solution, CO2 injection was conducted to induce sediment formation, resulting in a reduction in core permeability of approximately 16.01%. After CO2 mineralization and burial, the average porosity of the low-permeability core decreased by 7.07%, and the porosity change rate was positively correlated with porosity. The results of the CO2 storage experiment indicated that after the action of the 96% ethanol + 3-g KOH solution, CO2 could be effectively captured in the form of precipitates in the reservoir, with the largest degree of capture in medium to large pores. Compared with formation water, the composite solution studied in this paper can improve the CO2 storage efficiency by 30%. The 96% ethanol + 3-g KOH solution can accelerate the CO2 precipitation process in the reservoir and shorten the mineralization and storage time of CO2 in the reservoir. [Conclusions] This study proposed a new method to increase CO2 storage capacity by injecting a KOH + ethanol solution into a formation to improve CO2 mineralization and storage efficiency. Moreover, it realized the effective integration of the chemical industry and petroleum engineering disciplines and provided a new research approach for carbon peaking and carbon neutrality.

[Objective] Photothermal materials are materials that have strong absorption in the near-infrared region (760-1500 nm) and can convert the absorbed near-infrared light energy into heat, which have potential applications in the fields of energy conversion, photothermal imaging, bacterial infections, and photothermal treatment of tumors. However, the current preparation process of inorganic nano-photothermal materials has the problems of high cost, cumbersome synthesis process with long cycle time, and biocompatibility and cytotoxicity which bring some difficulties for clinical applications. In this paper, we propose to prepare near-infrared inorganic nanomaterials from pyritum (FeS2), a mineral drug included in the Chinese Pharmacopoeia, which has low cost, simple preparation process, abundant raw material sources, and excellent biocompatibility. Pyritum has the efficacy of dispersing blood stasis, relieving pain, renewing tendons and bones, and is mostly used for the treatment of bruises and injuries, tendon and bone fractures, bruises and pain, and it is one of the commonly used medicines in Chinese medicine for injuries in all the editions of Chinese Pharmacopoeia, which was firstly contained in Leigong Baozhi Lun in North and South Dynasties period, and has been used for more than 1,000 years, and there has not yet been any report on the preparation of nano-pyrophotothermal nanomaterials from the Chinese traditional Chinese medicine pyritum. [Methods] In this paper, the pyritum was calcined and then quenched in vinegar solution, after which it was finely ground into powder, which was mixed with surfactant F127 solution and put into ball mill for ball milling, and after ball milling, the powder was subjected to magnetic separation of impurities, and freeze-drying, which resulted in the desired photothermal nanomaterials of the mineral medicine pyritum. [Results] The prepared calcined pyritum nanoparticles are Fe7S8-dominated physical phase with Fe content of 60.62% at the calcination temperature of 800 °C, and have excellent light absorption properties in the wavelength range of 300 nm-800 nm,The pyritumprocessed product formed by roasting and vinegar quenching at 800 °C has many honeycomb and bubble-like protrusions and faults by acetic acid erosion, and is more easily crushed than the raw product. After ball milling for 6 h, the nanoparticles showed a hydrodynamic size of about 374.99 nm, an irregular spherical-like structure, and still in the physical phase of Fe7S8. Under the irradiation condition of near-infrared 808 nm wavelength light with a power of 0.39 W/cm², the temperature of the surface of the nanomaterials could be increased to 130.0 °C in 5 min, so they have an excellent photothermal effect. In the near-infrared five-cycle photothermal conversion experiments, the temperature of the 1st laser irradiated powder increased from 33.5 °C to 51.4 °C after 5 min; the temperature of the powder could be increased to -51 °C or so after 5 min of laser irradiation from the 2nd to the 5th time, which indicated that the photothermal performance of the concoction nanoparticles prepared by the pyritun fire calcination and vinegar quenching and ball milling and magnetic separation was stable. [Conclusion] This low-cost, simple preparation and synthesis process, good biocompatibility and excellent photothermal conversion ability of pyritum nanophotothermal materials have great potential for future applications in the biomedical field.
