In this paper, we propose a novel opportunistic scheduling-based antenna-user selection (OBAUS) scheme to improve the secrecy performance of cooperative non-orthogonal multiple access (NOMA) systems in the presence of a passive eavesdropper. The proposed

On the Secrecy Performance of Pinching-Antenna Systems
Pinching-antenna systems have recently gained significant attention as a novel reconfigurable-antenna technology due to its exceptional capability of mitigating signal-propagation path loss. In this letter, we investigate the secrecy performance of a pinching-antenna system in the presence of an eavesdropper.

ABSTRACT Objectives Acute kidney injury (AKI) is a common but often underrecognized complication in ischemic stroke patients undergoing mechanical thrombectomy, particularly among those with pre‐existing renal impairment. This study evaluated the incidence, risk factors, and clinical impact of AKI in this high‐risk population.

Secure Multiuser Communications in Wireless Sensor Networks with TAS and Cooperative Jamming
In this paper, we investigate the secure transmission in wireless sensor networks (WSNs) consisting of one multiple-antenna base station (BS), multiple single-antenna legitimate users, one single-antenna eavesdropper and one multiple-antenna cooperative ...

Secrecy and Performance Analysis of Symmetric Key Encryption Algorithms
There can be two vital criteria of selecting an algorithm to fulfil one’s encryption requirement. The security level of the cipher (secrecy) and the encryption time (performance). There is less focus on secrecy of ciphers as a security measurement, thus in this research, Shannon’s theories on secrecy of ciphers are used in-order to calculate the ...

ABSTRACT Objective Isolated rapid eye movement sleep behavior disorder (iRBD) is a prodromal state for Lewy body disorders and exhibits biological heterogeneity that may influence clinical expression and progression. We examined clinical features in individuals with iRBD and biomarker‐defined synucleinopathy.

ABSTRACT Background Collaterals are crucial factors that influence the infarct growth rate (IGR). We aimed to determine whether a comprehensive multimodal collateral score (MCS), incorporating collateral assessment at the arterial, tissue, and venous levels, is associated with functional independence and provides incremental prognostic value over ...
