This study aimed to investigate the relationship between mental health literacy(MHL)and workplace well-being(WWB)of Chinese grassroots civil servants,with regulatory emotional self-efﬁcacy(RESE)and resilience as mediating variables.A questionnaire survey was conducted among Chinese grassroots civil servants,with a valid sample size of 2673 after excluding missing values and conducting relevant data *** PROCESS was used to examine the relationship between MHL,RESE,resilience,and *** study found that MHL among grassroots civil servants was positively and signiﬁcantly correlated with WWB(r=0.73,p<0.01).RESE partially mediated the relationship between MHL and WWB(β=0.25,95%CI[0.22,0.28]).Resilience partially mediated the relationship between MHL and WWB(β=0.22,95%CI[0.19,0.26]).MHL had a positive effect on WWB through the chain mediating effect of RESE and resilience(β=0.05,95%CI[0.03,0.07]).There is a close relationship between MHL and WWB,where Chinese grassroots civil servants with higher levels of MHL can develop stronger RESE and resilience,leading to higher *** results of this study remind organizational institutions of Chinese grassroots civil servants that enhancing MHL,RESE,and resilience is an important pathway to promoting their WWB.

6G wireless technologies involve dense device deployment, utilize large-scale antenna arrays, and operate in the millimeter-wave and terahertz bands. This will shift the challenges of communication and sensing from the far field to the radiative near field, where traditional models and algorithms may incur errors or even become obsolete due to mismatch. Therefore, there is an urgent need to discuss localization and communication issues in the near-field region.

Degree of freedom (DOF) is a key indicator for spatial multiplexing layers of a wireless channel. Traditionally， the channel of a multiple-input multiple-output (MIMO) half-wavelength dipole array has a DOF that equals the antenna number. However， recent studies suggest that the DOF could be less than the antenna number when strong mutual coupling is considered. We utilize a mutual-coupling-compliant channel model to investigate the DOF of the holographic MIMO (HMIMO) channel and give a upper bound of the DOF with strong mutual coupling. Our numerical simulations demonstrate that a dense array can support more DOF per unit aperture as compared to a half-wavelength MIMO system.

实现无线环境的智能可控是无线通信领域研究的热门课题之一。作为6G的关键技术之一,智能超表面(Reconfigurable Intelligent Surface, RIS)被认为是一种革命性的电磁环境调控技术。RIS以绿色、低成本的方式显著提升网络性能,通过对发射机和接收机以及传播环境的联合优化,重新定义无线系统的传播范式,构建智能可控的无线传播环境。RIS通常依赖于无源被动调控机制,但这种机制带来乘性路径损耗问题,超大规模调控单元的部署十分必要。随着阵列尺寸的扩大以及频率的提高,传统的平面波假设不再适用,近场传输不可避免。为了更精确地刻画RIS近场传输,需要研究近场球面波的传输模型及其在辐射近场区域的影响。深入分析RIS辅助的近场无线通信系统的信道模型,针对性地设计了适应性预编码方案和传输策略,旨在充分利用RIS辅助近场通信的潜在优势,提升整个无线通信系统的性能和效率。
