随着我国医药卫生体制的深度改革,特别是分级诊疗制度的推进,全科医生在基层医疗保健体系中的角色日益重要。全科医生不仅是居民健康的第一道防线,更是常见疾病预防、诊断、治疗及健康教育的关键执行者。国家对全科医生提出了“小病善治、大病善识、重病善转、慢病善管”的临床定位。本文通过问答形式,分析“小、大、重、慢”疾病的分类与全科医生的“4善”定位,探讨全科医生在新医改时代下的重要职能及挑战。访谈者认为虽然分级诊疗制度旨在优化医疗资源配置,但在实践中仍面临“大、小、重、慢”疾病分类的模糊性和基层医疗资源的不均衡分配等问题。全科医生在这个体系中扮演着至关重要的角色,其需要具备综合的临床诊疗能力,并与专科医生共同制定临床判断标准和诊疗标准。为了应对这些挑战并充分发挥全科医生在现代医疗体系中的作用,迫切需要对全科医学教育和实践进行进一步改革与优化,同时强化全科医生的角色定位,以确保在提升医疗服务质量和效率的同时,实现公平和可持续的健康保障体系。

Electromagnetic interference (EMI) shielding inhigh-frequency range, especially the rapidly growing terahertz(THz) frequency range, attracts increasing attention due tothe potential application of terahertz in 6G wirelesscommunication, and security inspection. However, traditionalconductive EMI films typically achieve high shieldingeffectiveness through strong reflection, which may causesecondary pollution to other devices. Here, a gradientstructure strategy was proposed to constructTi_(3)C_(2)Tx/hydroxypropyl methyl cellulose (HPMC) film, in whichthe content of Ti_(3)C_(2)Tx gradually increases along the thicknessdirection, resulting in different conductivity of the two surfaces(surface-M and surface-H) for the film. The obtained gradientfilmexhibits an EMI shielding efficiency of over 48.5 dB in theTHz range (0.2-1.6 THz) at a thickness of 40 μm. Especially,as the THz waves incident from the surface-H to the film, the absorption effectiveness reaches 48.2 dB (average absorbedpower loss up to 91.4%), and the reflection effectiveness is only 0.3 dB. In additions, the gradient-film also demonstrates ahigh absorption rate of 95.5% in the infrared band (2.5-16.7 μm). Moreover, the gradient-film exhibits an excellent tensilestress and Young’s modulus value of 173.1 MPa and 2.8 GPa, respectively. Therefore, the gradient-film proposed in thiswork, with excellent electromagnetic absorption in both THz and infrared band, provides a promising candidate for the nextgenerationEMI shielding applications.

Variable Selection for the Partial Linear Single-Index Model

引用

Acta Mathematicae Applicatae Sinica 2017年第2期33卷 373-388页

作者： Wu wang zhong-yi ZHU Department of Statistics School of Management Fudan University Shanghai 200433 China

In this paper, we consider the issue of variable selection in partial linear single-index models under the assumption that the vector of regression coefficients is sparse. We apply penalized spline to estimate the nonparametric function and SCAD penalty to achieve sparse estimates of regression parameters in both the linear and single-index parts of the model. Under some mild conditions, it is shown that the penalized estimators have oracle property, in the sense that it is asymptotically normal with the same mean and covariance that they would have if zero coefficients are known in advance. Our model owns a least square representation, therefore standard least square programming algorithms can be implemented without extra programming efforts. In the meantime, parametric estimation, variable selection and nonparametric estimation can be realized in one step, which incredibly increases computational stability. The finite sample performance of the penalized estimators is evaluated through Monte Carlo studies and illustrated with a real data set.

Capacity and failure mechanism of laterally loaded jet-grouting reinforced piles: Field and numerical investigation

引用

Science China(Technological Sciences) 2016年第5期59卷 763-776页

作者： HE Ben wang Li zhong HONG yi College of Civil Engineering and Architecture Zhejiang University

This study presents the results of field and numerical investigations of lateral stiffness, capacity, and failure mechanisms for plain piles and reinforced concrete piles in soft clay. A plastic-damage model is used to simulate concrete piles and jet-grouting in the numerical analyses. The field study and numerical investigations show that by applying jet-grouting sur- rounding the upper 7.5D （D = pile diameter） of a pile, lateral stiffness and beating capacity of the pile are increased by about 110% and 100%, respectively. This is partially because the jet-grouting increases the apparent diameter of the pile, so as to en- large the extent of failure wedge and hence passive resistance in front of the reinforced pile. Moreover, the jet-grouting pro- vides a circumferential confinement to the concrete pile, which suppresses development of tensile stress in the pile. Corre- spondingly, tension-induced plastic damage in the concrete pile is reduced, causing less degradation of stiffness and strength of the pile than that of a plain pile. Effectiveness of the circumferential confinement provided by the jet-grouting, however, diminishes once the grouting cracks because of the significant vertical and circumferential tensile stress near its mid-depth. The lateral capacity of the jet-grouting reinforced pile is, therefore, governed by mobilized passive resistance of soil and plastic damage of jet-grouting.
