The benefits and challenges of highly parallel array coils for head imaging were investigated through the development of a 3T receive-only phased-array head coil with 96 receive elements constructed on a close-fitting helmet-shaped former. We evaluated several designs for the coil elements and matching circuitry, with particular attention to sources of signal-to-noise ratio (SNR) loss, includin...

Using a computational approach based on the driven diffusion equation for dipolariton wave packets, we simulate diffusive dynamics of dipolaritons in an optical microcavity embedded with transition metal dichalcogenide (TMDC) heterogeneous bilayer encompassing [Formula: see text]-shaped channel. By considering exciton-dipolaritons, which are three-way superposition direct excitons, indirect exc...

Introduction: Whole-volume surface coils have been demonstrated to deliver a high signal to noise ratio (SNR) in the near-surface region of the sample volume without diminution of the SNR in the center. In recent years, several musculo-skeletal MRI studies have ventured into the development of high channel count coils (> 4 elements) for knee imaging [1]. A 16-channel whole-volume coil array con...

Glass micromachining is a basic technology to achieve microfluidic networks for lab-on-a-chip applications. Among several methods to microstructure glass, the simplest and most widely applied is wet chemical etching (WE). However, accurate control of the reaction conditions to perform reproducible, fast and safe glass etching is not straightforward. Herein, microwave-assisted WE is demonstrated...

A three-dimensional (3D) fin-shaped field-effect transistor structure based on III-V metal-oxide-semiconductor field-effect transistor (MOSFET) fabrication has been demonstrated using a submicron GaAs fin as the high-mobility channel. The fin-shaped channel has a thickness-to-width ratio (TFin/WFin) equal to 1. The nano-stacked high-k Al2O3 dielectric was adopted as a gate insulator in forming ...

This paper proposes and describes a new method that can be used to schedule individual traffic flows, which share a common channel and have been shaped/policed by means of a Token Bucket (TB) mechanism. The method can also be extended to dynamically allocate bandwidth to this channel, based on information derived from TB states. Simulation results are presented and discussed.

Microfluidic designs are advantageous and are extensively used in number of fields related to biomedical and biochemical engineering. The objective of this paper is to perform numerical simulations to optimize the design of microfluidic mixers in order to achieve optimum mixing. In the present study, fluid mixing in different type of micro channels has been investigated. Numerical simulations a...

The achievable transmission capacity of conventional optical fibre communication systems is limited by nonlinear distortions due to the Kerr effect and the difficulty in modulating the optical field to effectively use the available fibre bandwidth. In order to achieve a high information spectral density (ISD), while simultaneously maintaining transmission reach, multi-channel fibre nonlinearity...
