An ophthalmic adaptive optics (AO) imaging system is especially affected by pupil edge effects due to the higher noise and aberration level at the edge of the human pupil as well as the impact of head and eye motions on the pupil. In this paper, a two-step approach was proposed and implemented for reducing the edge effects and improving wavefront slope boundary condition. First, given an imagin...

The slippery slope argument has been the mainstay of many of those opposed to the legalisation of physician-assisted suicide and euthanasia. In this paper I re-examine the slippery slope in the light of two recent studies that examined the prevalence of medical decisions concerning the end of life in the Netherlands and in Australia. I argue that these two studies have robbed the slippery slope...

T w o series of pyroxenes have been found in a layered teschenite sill, 22 m thick, emplaced in Late Permian coal measures in the Sydney Basin, New South Wales, Australia. The sill consists of 12 m of homogeneous teschenite, overlain by 6 m of picrite, then by 4 m of a layered sequence. The layering unit of this sequence is teschenite, a pyroxene-rich layer and a narrow leucocratic band. A whol...

Apparent particle size grading is the most important characteristic of super-high dumping site. On the basis of the development of the HHC-CA model and on-site survey of granular size distribution, the slope model of current situation, had considered the features of particle size grading, was established according to a super-high dumping site. FLAC was used to analyze the slope stability of cur...

The detectability of planetesimal impacts on imaged exoplanets can be measured using Jupiter during the 1994 comet Shoemaker-Levy 9 events as a proxy. By integrating the whole planet flux with and without impact spots, the effect of the impacts at wavelengths from 2 4 μm is revealed. Jupiter’s reflected light spectrum in the near-infrared is dominated by its methane opacity including a deep ban...

In this paper, a new algorithm to solve the discrete logarithm problem is presented which is similar to the usual baby-step giant-step algorithm. Our algorithm exploits the order of the discrete logarithm in the multiplicative group of a finite field. Using randomization with parallelized collision search, our algorithm indicates some weakness in NIST curves over prime fields which are consider...

We study the giant magnon solutions in the near horizon geometry of the Neveu-Schwarz (NS) 5-brane background. In conformal gauge, we find magnon dispersion relation in the large angular momentum (J) limit. We further show that the giant magnon poses uniform distribution of the angular momentum along the string world-sheet as in case of AdS5 × S5 spacetime.
