This paper describes tracking studies of FFAGs and radial-sector cyclotrons with reverse bends using the cyclotron equilibrium orbit code CYCLOPS. The results for FFAGs confirm those obtained with lumped-element codes, and suggest that cyclotron codes will prove to be important tools for evaluating the measured fields of FFAG magnets. The results for radial-sector cyclotrons show that the use o...

In this paper we address the problem of covering narrow indoor or outdoor pathways using a network of mobile Cyclops cameras. We propose and validate a 1D sensingperformance model for the detection behavior of the camera. Based on this, we formulate the covering problem as a new type of 1D locational optimization problem that explicitly accounts for the camera-location dependence of the sensing...

Pax6 and Pax2 are members of the Pax family of transcription factors that are both expressed in the developing visual system of zebrafish embryos. Pax6 protein is present in all cells that form the neural retina and pigment epithelium, whereas Pax2 is located primarily in cells that will give rise to the optic stalk. In this study, we have addressed the role of midline signalling in the regulat...

This research note reports on an on-going study of guinea worm infection, dracunculiasis, in Kwara State of Nigeria. Work already undertaken illustrates the linkage between urbanisation, population mobility and the recent rapid diffusion of the disease. Prevalence surveys are being carried out to identify the extent of the problem. Studies of local water sources and water collection practices a...

A 69 year old female presented in 2005, with painful swelling and discharging sinus of right ankle of 1 week duration. She was under treatment for bone marrow confirmed myelodysplastic syndrome. On examination she had pallor, swelling of the right ankle and a discharging sinus on the lateral aspect with a thick-thread like structure coming out of it. The thick-thread like structure was initiall...
