Design as a means of exploring the emotional component of scent

This paper demonstrates how industrial designers can generate engaging solutions by applying new technology to the area of scent-delivery through the use of practice-based research. It discusses works by Jason Morenikeji, Nick Rhodes and other designers contrasting these with developments in the scent and nano-technology industries. The paper also presents a series of designs by industrial designer Ben Hughes, namely ‘Fontenay aux Roses.’ It also includes a collection of wearable, smart interactive scent delivery devices designed for Jenny Tillotson’s e-Scent research project at CSM. 'Fontenay aux Roses 1' is a wearable bag-type device that houses a battery and pump unit to deliver three types of scent, controllable by the user. The prototype was made by award-winning bag designer Ann Chui. Fontenay is a brooch -type device that attaches to a garment with a magnetic snap-fastening. Three different snap-on covers show how the device might be customised by the user, branded by the scent manufacturer, or added to by a third-party. In both its design and its co-engineering by Murray Tidmarsh and Ben Hughes, it is an exploration of the use of rapid-manufacturing technology for this type of object. This work has evolved to incorporate devices for insect repellent under the title “E.Mos”, two of which Ben Hughes designed and created the prototype for

Four loop MSbar mass anomalous dimension in the Gross-Neveu model

We compute the four loop term of the mass anomalous dimension in the two dimensional Gross-Neveu model in the MSbar scheme. The absence of multiplicative renormalizability which results when using dimensional regularization means that the effect of the evanescent operator, which first appears at three loops in the 4-point Green's function, has to be properly treated in the construction of the renormalization group function. We repeat the calculation of the three loop MSbar beta-function and construct the beta-function of the evanescent operator coupling which corrects earlier computations.Comment: 20 latex pages, 7 figure

Capturing the essence of folding and functions of biomolecules using Coarse-Grained Models

The distances over which biological molecules and their complexes can function range from a few nanometres, in the case of folded structures, to millimetres, for example during chromosome organization. Describing phenomena that cover such diverse length, and also time scales, requires models that capture the underlying physics for the particular length scale of interest. Theoretical ideas, in particular, concepts from polymer physics, have guided the development of coarse-grained models to study folding of DNA, RNA, and proteins. More recently, such models and their variants have been applied to the functions of biological nanomachines. Simulations using coarse-grained models are now poised to address a wide range of problems in biology.Comment: 37 pages, 8 figure
