Microfluidics-based Low-Cost Medical Diagnostic Devices: Some Recent Developments

Low-cost, rapid-prototyping of digital microfluidics devices

An innovative and simple microfabrication method for digital microfluidics is presented. In this method, devices are formed from copper substrates or gold compact disks using rapid marker masking to replace photolithography. The new method is capable of forming devices with inter-electrode gaps as small as 50 lm. Saran wrap (polyethylene film) and commercial water repellants were used as dielec...

Some Recent Banking Developments

When I was invited to this banking conference, I agreed to talk about bank interest margins – in particular, the international comparison of these margins. As it turns out, we at the Reserve Bank have said about as much as can fruitfully be said on this subject in our recent Annual Report. Therefore, I will quickly summarise this subject in the first third of this talk, then move on to somethin...

Symbolic Summation | Some Recent Developments

In recent years, the problem of symbolic summation has received much attention due to the exciting applications of Zeilberger’s method for definite hypergeometric summation. This lead to renewed interest in the central part of the algorithmic machinery, Gosper’s “classical” method for indefinite hypergeometric summation. We review some of the recent (partly unpublished as yet) work done in this...

Some Recent Developments in Sphalerons

We review briefly the sphaleron and list some of its properties. We summarize some of the results in models which have an extended scalar sector. We also present our work on models dealing with physics beyond the standard model. We focus on the energy of the sphaleron which is important in determining the rate of baryon number violation at the electroweak scale.
