Paget's disease of bone has been known for about 100 years and the usual deformities of bone, e.g. bowed tibia, large head, are well described in medical text books. However, there does not appear to have been a description of corrugation of the skull as a recognized deformity in Paget's disease. Three cases are now described to illustrate this deformity as an unusual but valuable sign in this ...

Abstract. Improvements in the resolution of sea-floor mapping techniques have revealed extremely regular, sub-metre-scale ridge landforms produced by tidal flexure ice-shelf grounding lines as they retreated very rapidly (i.e. at rates several kilometres per year). Guided such novel observations from Thwaites Glacier, West Antarctica, we present three mathematical models for formation these cor...

We analyze the monthly average wind velocity at about 12 km above sea level, between 1980 to 1995, for San Pedro Mártir, Mauna Kea, another existing observatories and some sites of interest. We compare the results obtained from two different data sets, the GGUAS and NCEP. Our results show that San Pedro Mártir and Mauna Kea are comparable and are amongst the most suitable sites to apply slow wa...

Nanoscale surface corrugation strongly determines the plasmonic response of gold nanoparticles with dimensions of several tens of nanometres. Scattering spectra of individual spheres with a rough surface were found to red-shift and broaden. The plasmon modes exhibited quadrupole damping, in contrast to particles with smooth surfaces. Additionally, rougher spheres display a higher SERS activity,...

We perform high quality, first principles calculations of the properties of Pb and Tl isolated monolayers. Among these, we consider the equilibrium lattice constant, the two dimensional compressibilities and the electronic density. Comparison is made with previous results obtained using more simplified models. The present results represent an improvement concerning the calculated compressibilit...

We discuss the optimal evaluation of endothelial shear stress for real-life case studies based on anatomic data acquisition. The fluid dynamic simulations require smoothing of the geometric dataset to avoid major artefacts in the flow patterns, especially in the proximity of bifurcations. A systematic series of simulations at different corrugation levels shows that, below a smoothing length of ...
