The implementation of operating system functions can significantly affect the performance of parallel programs. In this paper, we describe our experience with a reconfigurable, multiprocessor threads package on a 32-node KSR1 supercomputer. We discuss static and dynamic configurations that address the on-line reconfiguration of threads schedulers and synchronization constructs. Experimental res...

Over the past 5 years or so, developmental geneticists studying the nematode and the fruit fly have provided many new insights into the signaling pathways linking cell surface receptor tyrosine kinases with nuclear transcription factors. A central component in this information transfer mechanism is the RAS protein, a low molecular weight GTP-binding protein that is a proto-oncogene product in m...

Abstract Amphibole-dominated dehydration melting of gabbro is the primary process responsible for genesis adakites, low-K tonalites, modern trondhjemites, and plagiogranites as well Archean tonalite-trondhjemite-granodiorite suites that represent earliest examples continental crust. Previous literature has mostly focused on role Al-rich amphibole during anatexis a mafic source many these studie...

The Chehel Kaman Formation of the upper Paleocene age formed from carbonate and siliciclastic sediments is located, in the Kapeh Dagh Sedimentary Basin. Two sections where considered for the purpose of research into the effective diagenetic processes of this formation. The Cheshmeh Qorban section with a thickness of 270.8m located 140km down the Mashhad – Sarakhs Highway while the Shourlog Sect...

According to the reports presented at the second Asian Radiology Forum (ARF) 2016, organized by the Korean Society of Radiology (KSR) during the Korean Congress of Radiology (KCR) in September 2016 in Seoul, there is an increasing need for the Asian-Oceanian Society of Radiology (AOSR) and its member societies to promote radiology together in the Asian-Oceanian region. In ARF 2016, the national...
