The role of psychological resilience in driving anger expression: The mediating effect of cognitive emotion regulation

Emotions that occur while driving, especially anger, can significantly impact driving-related safety. Due to the potential risks of aggressive driving behaviour, which include hazardous driving and traffic accidents, it is important to explore strategies to effectively manage anger, thereby enhancing driving-related safety. This study aimed to investigate the relationships among psychological resilience, cognitive emotional regulation, driving anger, and the expression of driving anger. A total of 350 drivers (aged 21&ndash;50 years) completed online questionnaires, including the Connor&ndash;Davidson Psychological Resilience Scale (CD-RISC), the Cognitive Emotion Regulation Questionnaire (CERQ), the Driving Anger Scale (DAS), and the Driver Anger Expression Inventory (DAX). The results indicated that a higher level of psychological resilience is associated with a greater tendency to employ positive cognitive emotion regulation strategies and a greater tendency to exhibit more adaptive expressions of driving anger. In contrast, a lower level of psychological resilience is associated with negative cognitive emotion regulation strategies, resulting in elevated levels of driving anger and a higher frequency of nonadaptive expressions. Additionally, cognitive emotion regulation mediated the relationship between psychological resilience and driving anger. These findings suggest that drivers with high levels of psychological resilience and those who engage in effective cognitive emotion regulation strategies are more likely to remain calm in irritating driving situations, thereby enhancing overall driving-related safety.</p

Broadband absorption tailoring of SiO2/Cu/ITO arrays based on hybrid coupled resonance mode

Sub-wavelength artificial photonic structures can be introduced to tailor and modulate the spectrum of materials, thus expanding the optical applications of these materials. On the basis of SiO2/Cu/ITO arrays, a hybrid coupled resonance (HCR) mechanism, including the epsilon-near-zero (ENZ) mode of ITO, local surface plasmon resonance (LSPR) mode and the microstructural gap resonance (GR) mode, was proposed and researched by systematically regulating the array period and layer thickness. The optical absorptions of the arrays were simulated under different conditions by the finite-difference time-domain (FDTD) method. ITO films were prepared and characterized to verify the existence of ENZ mode and Mie theory was used to describe the LSPR mode. The cross-sectional electric field distribution was analyzed while SiO2/Cu/ITO multilayers were also fabricated, of which absorption was measured and calculated by Macleod simulation to prove the existence of GR and LSPR mode. Finally, the broad-band tailoring of optical absorption peaks from 673 nm to 1873 nm with the intensities from 1.8 to 0.41 was realized, which expands the applications of ITO-based plasmonic metamaterials in the near infrared (NIR) region.Published versio

ITO-Induced Nonlinear Optical Response Enhancement of Titanium Nitride Thin Films

A series of TiN/ITO composite films with various thickness of ITO buffer layer were fabricated in this study. The enhancement of optical properties was realized in the composite thin films. The absorption spectra showed that absorption intensity in the near-infrared region was obviously enhanced with the increase of ITO thickness due to the coupling of surface plasma between TiN and ITO. The epsilon-near-zero wavelength of this composite can be tuned from 935 nm to 1895 nm by varying the thickness of ITO thin films. The nonlinear optical property investigated by Z-scan technique showed that the nonlinear absorption coefficient (β = 3.03 × 10−4 cm/W) for the composite was about 14.02 times greater than that of single-layer TiN films. The theoretical calculations performed by finite difference time domain were in good agreement with those of the experiments

This paper presents a groundbreaking Ku-band 20W RF front-end power amplifier (PA), designed to address numerous challenges encountered by satellite communication systems, including those pertaining to stability, linearity, cost, and size. The manuscript commences with an exhaustive discussion of system design and operational principles, emphasizing the intricacies of low-noise amplification, and incorporating key considerations such as noise factors, stability analysis, gain, and gain flatness. Subsequently, an in-depth study is conducted on various components of the RF chain, including the pre-amplification module, driver-amplification module, and final-stage amplification module. The holistic design extends to the inclusion of the display and control unit, featuring the power-control module, monitoring module, and overall layout design of the PA. It is meticulously tailored to meet the specific demands of satellite communication. Following this, a thorough exploration of electromagnetic simulation and measurement results ensues, providing validation for the precision and reliability of the proposed design. Finally, the feasibility of that design is substantiated through systematic system design, prototype production, and exhaustive experimental testing. It is noteworthy that, in the space-simulation environmental test, emphasis is placed on the excellent performance of the Star Ku-band PA within the 13.75GHz to 14.5GHz frequency range. Detailed power scan measurements reveal a P1dB of 43dBm, maintaining output power flatness </div
