An evaluation of the Cheshire Sexual Health Promotion project

This project report discusses an evaluation study of the Sexual Health Promotion project in Cheshire, which ran from 2000 to 2004.The project was commissioned by the steering group of the Sexual Health Promotion project and funded by South Cheshire Health Authority

Is it possible to establish reference values for ankle muscle isokinetic strength? A meta-analytical study

BACKGROUND: The importance of measuring ankle muscle strength (AMS) has been demonstrated in a variety of clinical areas. Much data has been accumulated using the Cybex Norm isokinetic dynamometer but a uniform framework does not exist. OBJECTIVE: To identify pertinent studies which have used the Cybex Norm to measure AMS in order to establish reference values. METHODS: A narrative review of the literature was used to identify papers that have used the Cybex Norm to measure isokinetic concentric and eccentric AMS. RESULTS: Fifty five research papers were identified but each study used a different isokinetic protocol. CONCLUSIONS: It is not possible to produce AMS reference values due to the wide variation in data collection methods. This is therefore an area of research that needs further exploration

The ISRS GN Model, an Efficient Tool in Modeling Ultra-Wideband Transmission in Point-to-Point and Network Scenarios

An analytical model to estimate nonlinear performance in ultra-wideband optical transmission networks is presented. The model accurately accounts for inter-channel stimulated Raman scattering, variably loaded fibre spans and is validated through C+L band simulations for uniform and probabilistically shaped 64-QAM

Towards 50G/100G Passive Optical Networks with Digital Equalisation and Coherent Detection

Increasing bandwidth demand in residential, business, and Wi-Fi/cellular backhaul applications means that passive optical networks (PONs) with dense wavelength division multiplexing and bit rates per wavelength channel of 50 or 100 Gb/s will soon be required [1]. However, PON technologies need to be low cost, particularly the optical network units (ONUs). Additionally, the high optical losses arising from the optical splitters used at remote nodes to distribute the signals to and from multiple ONUs, lead to the requirement for high receiver sensitivity. Coherent receivers, since they surpass the sensitivity limitations of the intensity-modulated direct-detection (IMDD) systems currently used, are an attractive solution [2] - [4]. Besides its sensitivity, coherent detection provides other advantages. The local oscillator achieves good wavelength selectivity, avoiding the need for narrow optical bandpass filters. The use of digital signal processing (DSP) enables spectrally efficient signalling and digital equalization of optical transmission impairments
