The ability of high performance Radar and Broadband Systems to detect weak targets in presence of strong interferers or clutter is given by their Spurious Free Dynamic Range (SFDR). Although the Signal-toNoise-Ratio (SNR) necessary for detection may be improved by well-known system processing gains, the dynamic range is ultimately limited by distortion terms caused by nonlinear behaviour of rec...

OBJECTIVES This study sought to determine the utility of quantitation of right ventricular (RV) function in predicting RV failure in patients undergoing left ventricular assist device (LVAD) implantation. BACKGROUND Clinical evaluation alone seems insufficient for predicting RV failure, an important cause of morbidity and mortality after LVAD implantation. METHODS Clinical, hemodynamic, and...

This paper presents a multi-bit reconfigurable intelligent surface (RIS) with high phase resolution, capable of beam-steering in the azimuthal plane at sub-6 Gigahertz (GHz). Field trials realistic indoor deployments have been carried out, coverage enhancement performance ascertained for three common wireless communication scenarios. Namely, serving users an open lobby mixed line sight and non-...

This work proposes an alternative to simulation-based receiver operating characteristic (ROC) analysis for assessment of fMRI data analysis methodologies. Specifically, we apply the rapidly developing nonparametric prediction, activation, influence, and reproducibility resampling (NPAIRS) framework to obtain cross-validation-based model performance estimates of prediction accuracy and global re...

A low noise 6th-order elliptic low-pass filter is proposed and implemented. For the high level integration of multi-standard wireless terminal at low cost, the direct conversion architecture is favored for the RF transceiver, and a low noise channel selection filter with enough out-of-band suppression takes a critical role for the direct conversion receiver. For the noise optimized filter desig...

Ubiquitous in-network caching is one of key features of Information Centric Network, together with receiver-drive content retrieval paradigm, Information Centric Network is better support for content distribution, multicast, mobility, etc. Cache placement strategy is crucial to improving utilization of cache space and reducing the occupation of link bandwidth. Most of the literature about cachi...

A bistatic radar network that consists of multiple separated radar transmitters (TXs) and receivers (RXs), aiming to detect a target on a set of points of interest (PoIs) is considered. The detection range of a bistatic radar depends on both locations of the TX and RX. The design of the bistatic radar network is investigated by studying the problem of optimally placing a number of radar transmi...

This paper presents an overview and description of the approach to be used to investigate the behavior and the defect sensitivity of various ultrasonic guided wave (UGW) modes propagating specifically in composite cylindrical vessels in the framework of the safety of hydrogen energy transportation such as hydrogen-powered aircrafts. These structures which consist of thick and multi-layer compos...

The Melbourne/Cochlear multiple-electrode extracochlear implant is designed for deaf patients who are unsuited to multiple-electrode intracochlear implantation. The implant consists of a receiver-stimulator package connected via a lead wire assembly to six individual stimulating electrodes. There is a choice of two alternative surgical procedures, both of which are via a combined middle ear app...

The role of birth parents in the management of childhood-onset long-term physical and mental health conditions is essential at many levels and continues throughout transition. For young people in local authority (LA) care, even if they have had a stable placement or social worker during their time in children's services, transition is a period when their social care support is likely to change....
