In this paper we present a construction of Kari-Culik aperiodic tile set — the smallest known until now. With the help of this construction, we prove that this tileset has positive entropy. We also explain why this result was not expected.

We give the inflation rules for the decorated Mosseri–Sadoc tiles in the projection class of tilings T . Dehn invariants related to the stone inflation of the Mosseri–Sadoc tiles provide eigenvectors of the inflation matrix with eigenvalues equal to τ = 1+ √ 5 2 and (−τ).

P, adioactive S-alkyl glycerol ethers have been synlhesized with 3SS, 14C and 3tt labels as well as 311/35S double labels. Tile synthesized compounds were converted to various derivatives which can serve to characterize tile S-alkyl glycerol ethers. These included tile isopropylidene derivative, oxidation with periodate to the aldehyde followed by reduction with LiAIH4 to tile alcohol, and reac...

This paper addresses the problem of compiling perfectly nested loops for multicomputers (distributed memory machines). The relatively high communication startup costs in these machines renders frequent communication very expensive. Motivated by this, we present a method of aggregating a number of loop iterations into tiles where the tiles execute atomically – a processor executing the iteration...

In this paper, we investigate the abilities of systems self-assembling tiles which can each pass a constant number signals to their immediate neighbors create replicas input shapes. Namely, work within Signal-passing Tile Assembly Model (STAM), and provide universal STAM tile set is capable creating unbounded numbers assemblies shapes identical those assemblies. The be arbitrary 2-dimensional h...

Through tile alignment of definitions fronl two or more dilTerent sources, it is possible to retrieve pairs of words that can be used indistinguishably in the same sentence without changing tile meaning of the concept. As lexicographic work exploits common defining schemes, such as genus and dilTerentia, a concept is simihu'ly defined by different dictionaries. The dilTerence in words used betw...

Programming a multicore processor is difficult. It is even more difficult if the processor has software-managed memory hierarchy, e.g. the IBM Cyclops-64 (C64). A widely accepted parallel programming solution for multicore processor is OpenMP. Currently, all OpenMP directives are only used to decompose computation code (such as loop iterations, tasks, code sections, etc.). None of them can be u...
