The aim of this study was to evaluate the differences in surgical capacity for head and neck cancer in the UK between the first wave (March‐June 2020) and the current wave (Jan‐Feb 2021) of the COVID‐19 pandemic.
Design
REDcap online‐based survey of hospital capacity.
Setting
UK secondary and tertiary hospitals providing head and neck cancer surgery.

3D technology facilitates reduction in wirelength by vertically stacking dies. Through-silicon-vias (TSVs) are used to connect inter-die signals, and the RC value of a single TSV depends on TSV dimensions, technology and used materials. The impact of TSVs on the delay also depends on the interaction between neighboring TSVs, on the length of wires connected to TSVs, and physical parameters of metal...
In this paper we derive sufficient conditions for passivity of neutral type time delay systems (TDS) with time varying parametric uncertainties. The delays in states and state derivatives are assumed to be time varying. Delay dependent sufficient conditions for robust passivity, are derived in terms of Linear Matrix Inequalities (LMIs). Feedback control law is formulated for robust passification of...
Channel estimation in orthogonal frequency division multiplexing (OFDM) systems is required for coherent demodulation. This paper deals with channel estimation in the OFDM based LTE system. In particular, two pilot-aided techniques are presented: the low-pass filter based estimator (LPFE), and the robust minimum mean square error estimator (MMSE). These techniques are characterized by their low complexity...
Integration between Ethernet Passive Optical Network (EPON) and Worldwide Interoperability for Microwave Access (WiMAX) is a promising solution for next generation access networks. In this paper, we devise a new architecture framework for EPON-WiMAX hybrid networks that is more reliable and extend the service coverage range. In addition, we propose a new bandwidth allocation algorithm for the proposed...
This paper addresses the impacts of RFID (radio frequency identification) adoption on the performance of emergency management organizations. The research question queries: What are the impacts of RFID adoption on the performance of emergency management operations? In order to investigate the hypothesized impacts including reduced response time, efficient tagging and tracking, compatibility, reduced...
