Using M(atrix) Theory, the dualities of toroidally compactified M-theory can be formulated as properties of super Yang Mills theories in various dimensions. We consider the cases of compactification on one, two, three, four and five dimensional tori. The dualities required by string theory lead to conjectures of remarkable symmetries and relations between field theories as well as extremely unu...

Several loop transformations techniques have been designed to extract parallelism from nested loop structures. We rst review two important approaches, known as Generalized Cycle Shrinking presented by Shang, O'Keefe and Fortes and the Index Shift Method introduced by Liu, Ho and Sheu. The main result of the paper is a new methodology that permits to combine cycle shrinking techniques with the i...

Advancements in technology have enabled the integration of a great amount of processor cores on a single silicon die, known as multi-core systems. Quite a few commercial designs have been launched into market in recent years, for example, nVidia 128-core GeForce 8800 GPU [77] and ARM11 PrimeXsys platform [7]. Some research groups even predicted that thousand-core processors would be commerciali...

At the end of 20th century, phenomenon urban shrinkage received widespread attention, with population decline as its core characteristic. In 2020, Taiwanese had negative growth and faced a low fertility rate an aging population. This study used exploratory spatial data analysis to identify shrinking cities in Taiwan based on census registers. The results indicated that has 11 counties 202 towns...

We report on a comprehensive investigation of the flow behavior of colloidal thermosensitive core-shell particles at high densities. The particles consist of a solid core of poly(styrene) onto which a network of cross-linked poly(N-isopropylacrylamide) is affixed. Immersed in water the shell of these particles will swell if the temperature is low. Raising the temperature above 32 degrees C lead...
