In the k-set agreement problem, each process proposes a value and has to decide a value in such a way that a decided value is a proposed value and at most k different values are decided. This problem can easily be solved in synchronous systems or in asynchronous systems prone to t process crashes when t < k. In contrast, it has been shown that k-set agreement cannot be solved in asynchronous sy...
متن کاملAlternative meiotic chromatid segregation in the holocentric plant Luzula elegans
Holocentric chromosomes occur in a number of independent eukaryotic lineages. They form holokinetic kinetochores along the entire poleward chromatid surfaces, and owing to this alternative chromosome structure, species with holocentric chromosomes cannot use the two-step loss of cohesion during meiosis typical for monocentric chromosomes. Here we show that the plant Luzula elegans maintains a h...

A framework for modelling memory consistency is presented. The framework is used to specify the operation of a total-store-order write buffer multiprocessor machine. The framework is used again to specify a more abstract “programmer-centric” model that does not refer to the write-buffer architecture. Finally, we prove that the abstract model correctly captures the computations of the operationa...
متن کاملD. G. C. Tasker
Born at Weston-super-Mare on the 25th May 1893, where his father was in business, he received his early education at Brynmellan School. From here in 1908 he entered the Medical School of the University College of Bristol, the year prior to the University receiving its charter. The Medical School was then situated in Tyndalls Park. A natural athlete, he played football, tennis and represented Gl...
متن کاملion desorption from condensed CD 4 ; C 2 D 2 ; C 2 D 4 ; C 2 D 6 and C 3 D 8 molecules induced by electron impact
The electron stimulated desorption of D anions from deuterated hydrocarbons condensed on a platinum substrate has been studied experimentally. D anion yield functions are reported for incident electron energies ranging from 0 to 20 eV: For each molecule studied, the yield function exhibits a single dissociative attachment resonance at approximately 10 eV: Above 15 eV; a linearly increasing D io...
