We characterize the wetting properties of graphene oxide by performing classical molecular dynamics simulations. With oxygen-containing functional groups on the basal plane, graphene becomes hydrophilic and the water contact angle decreases with their concentration, c. The concentration dependence displays a transition at c ≈ 11% as defined by the interacting range of hydrogen bonds with oxidiz...

The atmospheric wind and temperature can be estimated through the traveltimes of infrasound between pairs of receivers. The traveltimes can be obtained by infrasonic interferometry. In this study, the theory of infrasonic interferometry is verified and applied to modeled stratospherically refracted waves. Synthetic barograms are generated using a raytracing model and taking into account atmosph...

In most lineages, cell cycle exit is correlated with the growth of a primary cilium. We analyzed cell cycle exit and ciliogenesis in human retinal cells and found that, contrary to the classical view, not all cells exiting the cell division cycle generate a primary cilium. Using adhesive micropatterns to control individual cell spreading, we demonstrate that cell spatial confinement is a major ...

We address the problem of time to depth conversion of time migrated seismic images and show that the Dix velocities estimated from time migration velocities are the true seismic velocities divided by the geometrical spreading of image rays. We pose an inverse problem: to find seismic velocities from Dix velocities and suggest two algorithms for solving this problem. One algorithm is based on th...

Optical CDMA technology is being explored as a multiplexing technology for high speed access networks, with optical fibre as transmission medium and also processing ie. the spreading/dispreading of the CDMA sequences. For fibre-optic code division multiple access (FO-CDMA) scheme to be a practically implement able one as a high speed access network, two main challenges are, design of (1) codes ...

The term necrotizing fasciitis /NF/ was probably first described by Jones in 1871 as "hospital gangrene". NF, with its fast spreading from the local infection to massive necrosis of the underlying tissues, ie. superficial fascia and subcutaneous layers, is a potentially fatal disease, unless diagnosed early and properly treated. NF is more frequent in frail patients with chronic debilitating il...
