For secure communications, the authors propose a underwater wireless optical communications code-division multiple-access (UOWC/CDMA) system with multiple relay assistance. Relay nodes employ the Chip Detect-and-Forward (CDF) technique to prevent the difficult multiuser decoding procedure. The proposed system performance, in terms of bit-error rate (BER) and transmission confidentiality, is analyzed in our study over fading channel.

In this study, we suggested an FSO system with RIS assistance to mitigate the effects of signal blockage in the communication system, atmospheric turbulence, and UAV’s misalignment-induced fading. In a free-space environment with obstacles, the probability density function and cumulative distribution functions of an FSO system made up of RIS are derived.

This paper proposes a model reference adaptive control (MRAC) design for vehicle active suspension systems with unknown spring stiffness and damping coefficients with the aim of improving the performance of suspension systems. A mathematical model of a half-car active suspension system is first presented, then a reference model of a half-car suspension system that utilizes the skyhook damping concept is proposed.

This paper investigates the system performance of hybrid time-power switching based relaying (TPSR) energy harvesting enabled in the multisource half-duplex relaying network over the Rayleigh fading channel. The outage probability (OP) of the proposed system model with implementing maximal ratio combining (MRC) and selection combination (SC) technique at the receiver is presented and analyzed.

Hypertension is associated with the risk of prostate cancer (PCa) and its progression, however, it remains unclear whether antihypertensive medicines alter PCa risk or prognosis. This systematic review evaluated the role of calcium channel blockers (CCBs) and renin-angiotensin system (RAS) inhibitors in the risk and prognosis of PCa. This review was performed in line with PRISMA 2020 guidelines.

Primary tumor removal by cytoreductive nephrectomy in synchronous metastatic renal cell carcinoma patients has been investigated in the context of various treatment regimens. Two randomized controlled trials investigated the role and timing of cytoreductive nephrectomy in the era of targeted therapy and demonstrated that upfront nephrectomy should no longer be performed when patients require systemic therapy.
