Adeq...Dipole Research EXperiment（DREX） is a new terrella device as part of the Space Plasma Environment Research Facility（SPERF） for laboratory studies of space physics relevant to the inner magnetospheric plasmas. Adequate plasma sources are very important for DREX to achieve its scientific goals. According to different research requirements, there are two density regimes for DREX. The low density regime will be achieved by an electron cyclotron resonance（ECR） system for the ‘whistler/chorus＇ wave investigation, while the high density regime will be achieved by biased cold cathode discharge for the desired ‘Alfvén＇ wave study. The parameters of ‘whistler/chorus＇ waves and ‘Alfvén＇ waves are determined by the scaling law between space and laboratory plasmas in the current device. In this paper, the initial design of these two plasma sources for DREX is described. Focus is placed on the chosen frequency and operation mode of the ECR system which will produce relatively low density ‘artificial radiation belt＇ plasmas and the seed electrons, followed by the design of biased cold cathode discharge to generate plasma with high density.展开更多

This review explores the synergistic application of AI and HTE, highlighting their role in accelerating catalyst discovery, optimizing reaction parameters, and understanding structure-performance relationships. HTE facilitates the rapid preparation, characterization, and evaluation of diverse catalyst formulations, generating large datasets essential for AI model training. Machine learning algorithms, including regression models, neural networks, and active learning frameworks, analyze these datasets to uncover the underlying relationships between the data, predict performance, and optimize experimental workflows in real-time. Case studies across heterogeneous, homogeneous, and electrocatalysis demonstrate significant advancements, including improved reaction selectivity, enhanced material stability, and shorten discovery cycles. The integration of AI with HTE has significantly accelerated discovery cycles, enabling the optimization of catalyst formulations and reaction conditions. Despite these achievements, challenges remain, including reliance on researcher expertise, real-time adaptability, and the complexity of large-scale data analysis. Addressing these limitations through refined experimental protocols, standardized datasets, and interpretable AI models will unlock the full potential of AI-HTE integration.展开更多

In this paper, numerical studies for the generation of chorus-like waves in a launching device, dipole research experiment （DREX）, are carried out by a hybrid code. The DREX plasma is generated b} electron cyclotron resonance （ECR）, which leads to an intrinsic temperature anisotropy of energetic electrons. Thus the whistler instability can be excited in the device. We then investigate the effects of three parameters, i.e., the cold plasma density no, the hot plasma density nh, and the parallel thermal velocity of energetic electrons, on the generation of chorus-like waves under the DREX design parameters. It is obtained that a larger temperature anisotropy is needed to excite chorus-like waves with a high nc with other parameters fixed. Then we fix the plasma density and parallel thermal velocity, while varying the hot plasma density. It is found that with the increase of nh, the spectrum of the generated waves changes from no chorus elements, to that with several chorus elements, and then further to broad-band hiss-like waves. Besides, different structures of chorus- like waves, such as rising-tone and/or falling-tone structures, can be generated at different parallel thermal velocities in the DREX parameter range.展开更多

This experiment has been selected to be used for processing model development and validation in the international project DECOVALEX-2011. The con- ceptual and mathematical representation of the engineered void, which itself forms a major part of the experiment and is not simply a boundary condition, is the subject of this paper. A variety of approaches have been examined by the contributors to DECOVALEX and a summary of their findings is presented here. Two major aspects are discussed. Firstly, the approaches for the treatment of the surface condition at the porous media/tunnel interface are examined, with two equivalent but differing formulations successfully demonstrated. Secondly, approaches for representing the tunnel with associated air and water vapour movement, when coupled with the hydro-mechanical （HM） representation of the porous medium, are also examined. It is clearly demonstrated that, for the experimental conditions of the ventilation experiment （VE） that abstracted physical and empirical models of the tunnel, can be used successfully to represent the hydraulic behaviour of the tunnel and the hydraulic interaction between the tunnel and the surrounding rock mass.展开更多

基金the context of the international DECOVALEX Project (DEmonstration of COupled models and their VALidation against EXperiments)EC project NF-PRO (Contract number FI6W-CT-2003-02389) under the coordination of ENRESA (Empresa Nacional de Residuos Radiactivos)
文摘At the Mont Terri Underground Research Laboratory （Switzerland）, a field-scale investigation has been conducted in order to investigate the hydro-mechanical and chemical perturbations induced in the argilla- ceous formation by forced ventilation through a tunnel. This experiment has been selected to be used for processing model development and validation in the international project DECOVALEX-2011. The con- ceptual and mathematical representation of the engineered void, which itself forms a major part of the experiment and is not simply a boundary condition, is the subject of this paper. A variety of approaches have been examined by the contributors to DECOVALEX and a summary of their findings is presented here. Two major aspects are discussed. Firstly, the approaches for the treatment of the surface condition at the porous media/tunnel interface are examined, with two equivalent but differing formulations successfully demonstrated. Secondly, approaches for representing the tunnel with associated air and water vapour movement, when coupled with the hydro-mechanical （HM） representation of the porous medium, are also examined. It is clearly demonstrated that, for the experimental conditions of the ventilation experiment （VE） that abstracted physical and empirical models of the tunnel, can be used successfully to represent the hydraulic behaviour of the tunnel and the hydraulic interaction between the tunnel and the surrounding rock mass.
文摘Purpose: To explore practical experience in home care of nursing interns. Methods: The phenomenological method for qualitative research was to interview 15 nursing interns in a semi-structured way, and then the collected data were analyzed and summarized by using the Colaizzi analysis method. Results: Interviewing results showed that there were five recurring themes, including: 1) personalized care;2) health education;3) humanistic care;4) solid professional foundation and sense of responsibility;5) expanded vision. Conclusion: Through home care practice, nursing interns deepened their cognitions of nursing connotation, stimulated their love for nursing and motivation of continuous learning, and improved their sense of identity to nursing career. In general, the practice of home care had a positive impact on nursing interns.

文摘When designing a wave power plant,reliable and fast simulation tools are required.Computational fluid dynamics(CFD)software provides high accuracy but with a very high computational cost,and in operational,moderate sea states,linear potential flow theories may be sufficient to model the hydrodynamics.In this paper,a model is built in COMSOL Multiphysics to solve for the hydrodynamic parameters of a point-absorbing wave energy device.The results are compared with a linear model where the hydrodynamical parameters are computed using WAMIT,and to experimental results from the Lysekil research site.The agreement with experimental data is good for both numerical models.
文摘This article examines the critical integration of reflexivity,cultural sensitivity,and emergent design in qualitative psychiatry research focused on lived experiences.While quantitative methods offer essential clinical insights,qualitative approaches provide a deeper understanding of the emotional,psychological,and social dimensions of mental health.Reflexivity enables researchers to remain aware of how their personal biases and professional backgrounds shape data interpretation.Cultural sensitivity ensures that mental health conditions are understood within their broader cultural contexts,helping avoid misrepresentation and promoting authentic participant expression.Emergent design offers flexibility in adapting the research process to evolving themes,particularly in the dynamic and multifaceted realm of psychiatric conditions.Together,these principles promote ethically sound,participant-centered research that captures the full complexity of lived experiences.The article also highlighted the practical implications of these principles for enhancing both academic knowledge and clinical practice in psychiatry.
