Abstract Memory safety bugs continue to be a major source of security vulnerabilities in our critical infrastructure. The CHERI project has proposed extending conventional architectures with hardware-supported capabilities enable fine-grained memory protection and scalable compartmentalisation, allowing historically memory-unsafe C C++ adapted deterministically mitigate large classes vulnerabil...

The human hand has been used in art from the very beginnings, starting with stunning examples in Neolithic cave paintings. Early examples of the fist in graphic art can be found at least as far back as 1917 [1], with another example from Mexico in 1948 [2]. Fist images, in some form, were used in numerous political graphic genres, including the French and Soviet revolutions, the United States C...

Using data from the Southern Galactic Plane Survey we present a possible distant spiral arm in the fourth quadrant of the Milky Way. The very distinct and cohesive feature can be traced for over 70 as the most extreme positive velocity feature in the longitude-velocity diagram. The feature is at a Galactic radius between 18 and 24 kpc and appears to be the last major structure before the end of...

Several muscular degenerative diseases alter motor abilities of large muscles but spare smaller muscles, e.g. keeping hand motor skills relatively unaffected while upper limbs ones are altered. Thus, hand movements could be be used to control an arm exoskeleton for rehabilitation and assistive purpose. Using an infra-red sensors (IR) based interface for the exoskeleton control, this paper descr...

Stratospheric measurements of acetylene up to altitudes of 30 km are presented. The air samples were collected during three different balloon flights, two of them at 44°N, one at nON using balloon borne, liquid neon-eooled, cryosamplers. Their acetylene concentration was measured in the laboratory by flame ionisation gaschromatography. The different profiles at nON and 44°N are discussed with r...

A new visual illusion is presented. When two neon-coloured illusory bands overlap each other, the filling-in at the region of overlap is perceived as different from those of the overlapping bands, resulting in an additional illusory shape at the region of overlap. An experiment with ten na|« ve participants was performed to measure the illusory percept. The results show that illusory surfaces m...
