Abstract Dynamical controls on terahertz (THz) wavefronts are crucial for many applications, but available mechanism requests tunable elements with sub-micrometer sizes that difficult to find in the THz regime. Here, different from local-tuning mechanism, we propose an alternative approach construct wavefront-control meta-devices combining specifically designed metasurfaces and globally tuned graphene layers. Coupled-mode-theory (CMT) analyses reveal serves as a loss drive whole meta-device...
We quantify the impact of residual hardware impairments (RHI) on a non-orthogonal multiple access (NOMA)-based relaying network, where source communications simultaneously with users via an amplify-and-forward relay. Specifically, exact and asymptotic expressions for outage probability are first derived in closed-form over Nakagami-m fading channels, accounting RHI at source, relay, all users. Our results show that performance loss induced by is small low signal-to-noise ratio (SNR) regime...
In this paper, a polarization-insensitive high transmittance bandpass filter with low radar cross section (RCS) in both S- and X-band is proposed. This the first study to use partition layout loading approach for conformal structures transmissive windows, reducing operating band RCS. Curved have stronger radiation at smaller angle incident wave, that how their scattering differs from uniform flat structures. The structure divided by analyzing radiative contribution of different regions....
Sleep quality is crucial for the personal well-being of healthcare professionals and health outcomes their patients. This study aims to explore relationship between psychological resilience (PR), perceived social support (PSS), distress (comprising anxiety,depression,and stress), sleep quality. It also examines whether PSS function as chain mediators PR A cross-sectional online survey was conducted using a convenient sampling method, with 454 participants included. The instruments included...
Medical staff are direct providers of medical services and a key element in the development health services, their life satisfaction is important to both work patients’ satisfaction, subsequently influencing quality care general. This cross-sectional study aimed explore mechanisms underlying influence perceived social support on staff’s satisfaction. Convenience sampling was used recruit participants from two non-tertiary hospitals Shaoguan City, Guandong Province, China. A total 533...
The study of synergistic drug combinations is vital in cancer treatment, enhancing efficacy, reducing resistance, and minimizing side effects through complementary actions. Drug-drug interaction (DDI) analysis offers essential theoretical support, with the rise data science, intelligent algorithms are increasingly replacing traditional vitro screening for predicting potential DDIs. Considering limitations previous computational methods, such as application a single view, overly direct...
The effect of unilateral and bilateral bone-filling mesh containers (BFC) on osteoporotic vertebral compression fracture (OVCF) was analyzed by the finite element method. CT scan data T12-L2 body were obtained from a healthy female volunteer with no history lumbar spine injury or obvious abnormality morphology. normal model osteoporosis established, models validated. L1 in used to simulate fracture, after which BFC simulated establish representing two surgical approaches. We changes...
Abstract Tracking and associating different views of the same target across moving cameras is challenging as its appearance, pose scale may vary greatly. Moreover, with multiple targets a management module needed for new entering old exiting field view each camera. To address these challenges, we propose DMMA, Distributed Multi-camera Multi-target Association real-time tracking that employs coupled local data-structure containing information on targets. The shares appearance label known...

This paper considers the application of polar codes in image transmissions. When codeword length is finite, information bits different positions experience but predictable unequal post-decoding error probabilities. Exploiting this property, we propose to order a according their erroneously transmission induced distortions. Specifically, most significant (MSB, left-most bits) each pixel an are transmitted through lower probability bit-channels (logical channel post code) and Least Significant...
