An efficient method to measure reliability of underwater acoustic communication links
Journal of Ocean Engineering and Science, 2016 We consider the problem of evaluating the reliability of underwater acoustic communication (UWAC) systems. Reliability is a requirement for any communication system and is often defined as the probability to achieve a target bit error rate. Evaluation of

High Performance Robust Adaptive Beamforming in the Presence of Array Imperfections
International Journal of Antennas and Propagation, 2016 A high performance robust beamforming scheme is proposed to combat model mismatch. Our method lies in the novel construction of interference-plus-noise (IPN) covariance matrix. The IPN covariance matrix consists of two parts.

A novel adaptive beamforming scheme for array signal data processing
EURASIP Journal on Wireless Communications and Networking, 2023 When the desired signal data exists in the array received data or the steering vector has a mismatch problem, the current traditional adaptive beamformers will suffer from the effect of the desired signal cancelation phenomenon, resulting in a sharp ...

Molecular Oncology, EarlyView.This study identifies somatostatin receptor 4 (Sstr4) as a critical tumor suppressor against skin and head/neck cancers (HNSCC, cSCC, and BCC). The loss of Sstr4 removes a check on cell growth, causing hyperactivation of the MAPK‐ERK signaling pathway (↑).

FEBS Open Bio, EarlyView.KDAC6 has been associated with cell motility and actin structures, but specific domain contributions are not established. The two catalytic domains have differential effects on motility and F‐actin regulation, affecting cortical F‐actin density, motility, stress fibers, and cell spreading.

Efficient joint power allocation for mitigating intracluster interference in clustered NOMA system
ETRI JournalIn recent years, the growing demand for massive connectivity has focused researchers’ attention on next-generation radio access techniques. Nonortho-gonal multiple access (NOMA) is a candidate for supporting massive connec-tivity.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Neurochemical levels measured by brain MR spectroscopy (MRS) have been proposed as endpoints for clinical trials in early‐stage spinocerebellar ataxia (SCA) trials. We tested their trial‐readiness by quantifying neurochemicals in three affected brain regions in early‐stage cohorts of SCA2 and SCA3, examining their reproducibility in ...

Joint transceive beamforming for multistatic radar system by semi‐definite relaxation method
IET Radar, Sonar & NavigationThe joint transmit and receive beamforming algorithm has been envisioned to optimise the target's signal‐to‐interference‐plus‐noise ratio by co‐designing the transmit and receive beamforming vectors simultaneously.
