The CBEM spiking neuron model establishes a new connection between the statistics of neural coding and the biophysical model. In order to narrow the gap between the CBEM model and the biophysical model, a coupled CBEM spike neuron model is proposed. A coupling filter was used to couple the single CBEM model. The correlation between different spiking sequences is considered in the coupled CBEM spiking neuron model, and the correlation information is used for sequence fitting. Through the spike rate visualization, Single-spike information and the AIC criterion show that the proposed coupled CBEM model can obtain more real spiking sequences simulation results, more spiking sequences information and the low model complexity while retaining the biophysical interpretability.

Background As the gatekeepers for rural residents' health, rural doctors are the main providers of health management services for rural populations. Their community health management ability directly affects the health level of rural residents. Objective This study aims to investigate the current status of health management ability of rural doctors in China and explore strategies for enhancing their community health management ability, thus providing a basis for strengthening the building of a rural doctor team. Methods In August 2020, a multi-stage stratified cluster sampling and purposive sampling methods were used to select 3 916 rural doctors from five provinces in east, central, and western China. Rural doctors were surveyed using an online questionnaire platform called "Wenjuanxing". The questionnaire content included the rural doctors' ability to manage the health of children, women, elderly, and chronic disease patients, and the degree to which these needs were met, all of which were self-evaluated by the rural doctors. Results Of the 3 916 rural doctors surveyed, 3 494 (89.22%), 3 175 (81.08%), 3 775 (96.40%), and 3 738 (95.45%) were found to had the ability to manage the health of children, women, the elderly, and patients with chronic diseases, respectively. The ability of female rural doctors to provide family planning guidance, prenatal health guidance, prevention and treatment of menopause-related diseases, and screening for common gynecological diseases was better than that of male rural doctors (P

Electrochemical technology detects analytes based on their electrochemical signals. Due to its advantages of simple operation, low cost, high precision and sensitivity, the application of electrochemical technology in food detection and analysis has attracted much attention, and some research progress has been made. In this article, the types, basic principles and applications of electrochemical methods in the field of food detection are reviewed, and prospects for the application and development of electrochemical technology are discussed to provide a reference for promoting the application of electrochemical technology in the field of food detection and analysis in order to meet the development needs of rapid food detection and analysis.
