In this letter, we investigate a reconfigurable intelligent surfaces (RIS)-aided device to (D2D) communication system over Rician fading channels with imperfect hardware including both impairment at the transceivers and phase noise RISs. This letter has optimized shift by genetic algorithm (GA) method maximize achievable rate for continuous shifts (CPSs) discrete (DPSs). We also consider two sp...

Conventional centralized authentication techniques based on both digital cryptography and physical-layer attributes are prone to single-point failure due either compromised security keys or an abrupt change in the physical communication environment. Although these particular challenges could be mitigated by joint use of decentralized attributes, such schemes often exhibit unpredictable performa...

TeraHertz (THz) wireless communication constitutes a promising technique of satisfying the ever-increasing appetite for high-rate services. However, ultra-wide bandwidth THz communications requires high-speed, high-resolution analog-to-digital converters, which are hard to implement due their high complexity and power consumption. In this paper, deep learning-assisted receiver is designed, reli...

Educators increasingly request that child mental health clinicians in outpatient and school settings provide guidance about how to assess children who may carry weapons to school or who may pose a potential threat to the school community. They may also request help in determining if a student’s aggression is exacerbated by an untreated psychiatric disorder.Many schools have to make critical jud...
