Recent research has shown that implementations with variable execution timing may allow attackers to extract secret cryptographic keys stored on the device. Timing variances can occur due to implementation choices (e.g. data-dependent branches) or due to the internal architecture of the processor core (e.g. cache lines). In order to overcome this problem one needs to find alternative implementa...

From 4-5 June 2002 a group of 22 participants and 3 observers (See appendix) gathered in Boulder, Colorado to develop a plan for standardized equipment needs and measurements for all NEON observatories. As in previous workshops, the group enthusiastically endorsed the proposed development of a national network of ecological observatories. This report provides examples of how NEON will expand re...

Aims. To determine the neon-to-oxygen abundance in the quiet Sun, a proxy for the photospheric abundance ratio. Methods. An emission measure method applied to extreme ultraviolet emission lines of Ne iv–vi and O iii–v ions observed by the Coronal Diagnostic Spectrometer on the SOHO satellite. is suggested, in good agreement with the most recent compilation of solar photospheric abundances, but ...

'Filling-in' occurs when a retinally stabilized object subjectively appears to vanish following perceptual fading of its boundaries. The term 'filling-in' literally means that information about the apparently vanished object is lost and replaced solely by information arising from the surrounding background. However, we find evidence that the mechanism of 'filling-in' can actually involve a proc...

Fraunhofer diffraction patterns of human enamel samples were photographed with a helium-neon laser beam (lambda = 633 nm). The first-order diffraction angle was in reasonable agreement with a prediction based upon enamel prisms acting as a two-dimensional grating. These results support the hypothesis that enamel diffracts light because of the periodic structure of enamel prisms with interprisma...

The diffusion of Ne in Ag is investigated by bombarding Ag sheet with energetic Ne ions and observing the Ne release during constant temperature anneals; giving D=2.5 * 1.5 exp (-59.5 5 2.0 x 103 Cal/mole/ RT), for volume diffusion. The activation energy is not consistent with previous values found for other inert gases in Ag but agrees with the predictions of impurity diffusion theory for diff...

Neon Racer is a multi-user Augmented Reality racing game adapting the simple and powerful gameplay of racing games to an Augmented Reality tabletop setting. The game combines an intuitive and tangible interface with quality content. The active setting for the game is provided by the real world. Physical objects act as collision obstacles and influence the course of the race itself. In this pape...
