单位制度变迁视阈下社会转型对医患信任的影响

社会转型是医患信任嬗变的历史背景,医患信任嬗变是反映社会转型的基本侧面,单位制度变迁是透视二者关系的良好视角。新时期我国社会转型的重要表现是从“熟人社会”转向“生人社会”,直接引发了医患关系从互信到互不信的明显转变。“熟人社会”中医患信任主要是基于熟悉的人际信任,“生人社会”则呼唤基于规范的制度信任。人际信任加速失效、制度信任尚未完全建立造成信任结构断裂是医患信任危机发生的根源。“人际信任”与“制度信任”各有优势和不足,重建医患信任必须努力实现二者的有机结合。

Algorithm for Determining Time Series of Phase Transformations in the Solid State Using Long-Short-Term Memory Neural Network

In the numerical analysis of manufacturing processes of metal parts, many material properties depending on, for example, the temperature or stress state, must be taken into account. Often these data are dependent on the temperature changes over time. Strongly non-linear material property relationships are usually represented using diagrams. In numerical calculations, these diagrams are analyzed in order to take into account the coupling between the properties. An example of these types of material properties is the dependence of the kinetics of phase transformations in the solid state on the rate and history of temperature change. In literature, these data are visualized Continuous Heating Transformation (CHT) and Continuous Cooling Transformation (CCT) diagrams. Therefore, it can be concluded that time series analysis is important in numerical modeling. This analysis can also be performed using neural networks. This work presents a new approach to storing and analyzing the data contained in the discussed CCT diagrams. The application of Long-Short-Term Memory (LSTM) neural networks and their architecture to determine the correct values of phase fractions depending on the history of temperature change was analyzed. Moreover, an area of research was elements that determine what type of information should be stored by LSTM network coefficients, e.g., whether the network should store information about changes of single phase transformations, or whether it would be better to extract data from differences between several networks with similar architecture. The purpose of the studied network is strongly different from typical applications of artificial neural networks. The main goal of the network was to store information (even by overfitting the network) rather than some form of generalization that allows computation for unknown cases. Therefore, the authors primarily investigated in the ability of the layer-based LSTM network to store nonlinear time series data. The analyses presented in this paper are an extension of the issues presented in the paper entitled “Model of the Austenite Decomposition during Cooling of the Medium Carbon Steel Using LSTM Recurrent Neural Network”.

冷适应过程中大鼠脑垂体、下丘脑和血浆生物活性肽的变化及其对免疫功能的影响

我们采用RP-HPLC方法研究了SD纯系雄性大鼠冷适应期间脑垂体(P)、下丘脑(HT)和血浆(BP)生物活性肽变化。冷适应期间P、HT和BP肽类(MW≤30000)RP-HPLC图谱均出现一些新的肽洗脱峰。而且,所有这些肽类都能增强淋巴细胞(LC)转化活性。在P和HT肽类刺激下,脾LC[~3H]-TdR参入分别增加725 cpm(P<0.01)和1274 cpm(P<0.001)。将这些肽类进一步经Sep-Pack C_(18)柱纯化后仍分别增加[~3H]-TdR参入cpm值597(P<0.05)和333。这些结果表明了免疫系统(ImS)与神经内分泌系统(NES)双向调节环路的一个方面:NES作用于ImS。     

Predictions and Experiments on the Distortion of the 20Cr2Ni4A C-ring during Carburizing and Quenching Process

This paper focuses on the effect of gear steel on distortion due to phase transformation in carburizing and quenching. The carburizing and quenching process of C-rings under suspension was studied by using the finite element method based on the thermo-mechanical theory, considering phase transformation. The phase transformation kinetics parameters, depending on different carbon contents, were measured by Gleeble-3500. The distortion behavior of the carburized C-ring during the cooling stage was analyzed, as well as the carbon concentration distribution and martensite volume fractions. The accuracy of the simulation was also verified by comparing the experimental data with the simulated result of the distortion and microstructure. A reliable basis is provided for predicting the distortion mechanism of gear steels in carburizing and quenching.
