A methodology for evaluating wound care products in complex chronic wounds
No full textThe question of whether particular methodologies can generate knowledge of a sufficiently rigorous and relevant standard to guide patients’ interventions is regularly debated. This debate tends to be polarised between those who advocate the randomised controlled trial (RCT) as the ultimate scientific methodology and those who find RCTs wanting in terms of the information derived and their limited generalisability beyond the immediate trial population. This paper argues for a suite of methodologies that can evaluate wound care interventions; it also details a novel methodology for use in complex chronic and palliative wound care.Aim: To outline a methodology that can evaluate the clinical performance of wound care products in the context of complex treatment and care.Methods: The methodology is informed by the UK Medical Research Council framework for the design of complex evaluations, and is an N-of-1 design.Results: A novel methodology for evaluating the effectiveness of wound care technologies in complex chronic wound care and palliative wound care has been proposed.Conclusion: The methodology requires validation in prospective studies. The purpose of this paper is to open a constructive debate

Tapered silicon core fibres for supercontinuum generation
No full textA series of silicon-core fibre tapers are designed that allow for longitudinal variation of their nonlinear and dispersion parameters with length. A supercontinuum (SC) is generated in the waist region of the taper due to the increased nonlinearity there. The long-wavelength edge of the SC is then boosted by up-tapering to a specific core diameter which is chosen to optimise the phase-matching conditions for four-wave mixing. This means that the bulk of the initially-generated SC can be used as pump sources for transferring power to the long-wavelength edge. Each design targets a specific wavelength range with a 0.25 µm bandwidth. The design work is driven by simulations of mid-infrared laser pulse propagation through the fibres, which work by solving the generalised nonlinear Schrödinger equation (GNLSE). This incorporates numerous nonlinear effects in silicon affecting SC generation, including two-photon absorption (TPA), three-photon absorption and free-carrier effects. The wavelength-dependence of linear loss and the effective area of the fundamental mode is incorporated into the GNLSE, which is extended to also incorporate the wavelength-dependence of TPA. The possibility of using these taper design principles is also explored for silicon on-insulator waveguides
